detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following, in which the technical solutions in the embodiments of the present application are clearly and completely described. The embodiments are only a part of the embodiments of the present application, and not all of them. Based on the embodiments in the present application, those of ordinary skill in the art obtain the following without creative work. All other embodiments obtained are intended to fall within the scope of the present application.

1 is a schematic view of a stone mining equipment according to an embodiment of the present application, which mainly includes a base 100, a cutting unit 200, a grinding unit 300, and a driving unit, wherein the driving unit is not shown in the figure. The entire stone mining equipment is described in detail below with reference to FIG. 2 to FIG. 10: the cutting unit 200 includes a plurality of transmissions 201 that are arranged side by side on the edge of the base body. In addition, the transmission unit 201 is provided with a cutting head 202, and the cutting head 202 is specifically See Figure 9 and Figure 10 for the shape. The number of transmissions 201 is plural, and is arranged side by side in the slots 101 of the edge of the base 100, and at least two of the plurality of transmissions are opposite in rotation when rotated about the base; the drive unit and the cutting unit 200 are further Cooperate, the transmission 201 for driving the cutting unit 200 is rotated about the base.

The above mentioned at least two of the plurality of transmissions have opposite rotation directions when rotating around the base body, so the number of the driving units herein may be plural or one, wherein the one driving unit includes a plurality of sub driving units. When the driving unit drives the transmission device, part of the driving unit (drive subunit) drives the transmission device to rotate clockwise along the base body, and part of the driving unit (drive subunit) drives the transmission device to rotate counterclockwise along the base body.

In addition, as can be seen from FIG. 1, the grinding unit 300 includes a grinding plate mounted on the side of the base body 100 and protruding from the side of the base body. The number of the grinding discs herein may be one or more, and only two in FIG. For example, a grinding disc. Thus, after the cutting unit is cut forward, the above-mentioned protrusion of the base grinding sheet can serve the purpose of grinding the cutting surfaces on both sides of the slit in time.

One of the preferred embodiments is that the number of the transmissions 201 is two, and the two transmissions are opposite to each other in the direction of rotation of the base. Similarly, the number of the slots 101 on the outer edge of the base 100 is two, and one slot 101 is mounted. The transmission 201, the schematic diagram of the slot 101 can be specifically seen in FIG. The transmission 201 herein may be specifically a chain, and of course other shapes, such as a flexible metal string, such that the cutting heads 202 are evenly distributed at a periphery of the transmission 201 at a certain interval. When the transmission device 201 is specifically a chain, the cutting head 202 can be mounted and fixed on the periphery of the chain at a predetermined interval, and the cutting blade of the cutting head 202 faces outward, as shown in FIG. 7 in addition, and can also be cut. The driving hole 203 and the chain hole 204 are disposed on the head 202, and the chain is passed through the chain hole 204 for the purpose of connecting and fixing the cutting head. Then, the driving unit is used to drive the transmission device to rotate around the base 100 through the driving hole 203.

It should be noted that the driving unit herein may be specifically a driving gear, and may of course be other The driving method is as long as it can drive the transmission to rotate around the base. Another implementation manner is that the driving unit is specifically a driving gear, and the transmission device is specifically a chain, so that a card slot can be arranged on the chain, and the card slot meshes with the gear teeth of the driving gear, and finally the driving gear rotates to drive the chain. Rotating around the substrate, the device can continuously cut the stone before the device or other materials through the chain around the periphery of the substrate and the cutting head disposed on the chain during the forward movement, and is installed on the side of the substrate at the same time. The grinding piece protruding from the side of the base body smoothes the cutting faces on both sides of the kerf, and the effect of mining and grinding is synchronized.

In other embodiments of the present application, the transmission and the cutting head may be assembled together by assembly, and of course may be directly a unitary member, such as a chain with a cutting head, such that the transmission is integral with the cutting head. It is no longer necessary to securely connect the transmission to the cutting head through the chain holes as described in the above embodiments. Either way, as long as the above-described integral transmission and cutting head, or the transmission and the cutting head that are separated and assembled together, surround the edge of the base 100 and can rotate around the base 100, can.

When the stone mining equipment provided by the embodiment of the present application is used for mining stone, the driving unit drives the transmission device, thereby driving the cutting unit to rotate around the base body, and the cutting head on the cutting unit cuts the rock according to a preset direction, thereby forming a slit on the rock. At the same time, the grinding unit located on the side of the base body and protruding from the side of the base body smoothes the surface of the stone on the side of the slit, which reduces the process of stone mining in the prior art and improves the mining efficiency of the stone. For example, the mining stone is taken as an example. Of course, the technical solution provided by the embodiment of the present application is not limited to mining stone, and can also be used for cutting materials such as concrete materials and soft materials.

It should be noted that the stone mining equipment provided by the embodiments of the present application may also need some other process cooperation when mining the stone, for example, the non-stone material of the mine is stripped, the large surface of the mining is flattened, and then the equipment can be used for cutting. Grinding, so as to form a slit, and finally only need to borrow other equipment to cut the bottom of the stone that has been cut and polished, and cut it into a plate of the specification size, omitting the exploitation of the stone material in the prior art - the stone material is corrected to Blocks - the logistics of the blocks to the processing area - the finishing of the surface of the large cut - large cut - rough grinding - fine grinding and other processes.

The above is only a brief introduction to the main components of the stone mining equipment and the way of working. The details of the main components of the entire stone mining equipment, the preferred alternatives or the components that can be included in the entire equipment are detailed below. For example, for the above-mentioned substrate, the shape of the substrate can also Other shapes such as a sector, a semicircle, a circle, or a star shape may be such that the cutting unit can be rotated around the base of the above shape. The shape of the base body shown in FIG. 2 is only a preferred solution. When the apparatus is used for the production of the base body shown in FIG. 2, the plates of different widths can be mined by controlling the depth of the feed, and the equipment is continuously cut forward to form a length direction. Restricted sheet.

Since the stone mining equipment provided by the present application comprises a large number of constituent units, in order to facilitate the distinction, some constituent units may be combined and replaced by a name, for example, a unit body in which a base body, a cutting unit and a grinding unit may be combined. For a cutting group, the number of the above cutting groups can be one, of course, it can also work for multiple parallel working, and the cutting groups working in parallel can double the mining efficiency, as long as the cutting groups are kept according to the requirements of the stone mining specifications. The intervals are separated, and the plurality of cutting groups are fixedly connected by a central axis. By controlling the interval between the cutting groups, the thickness of the finally formed cut sheet can be controlled.

As can be seen from the foregoing, the number of transmissions is plural, and is wound in parallel in the slots of the edge of a base body. The plurality of transmissions can rotate a plurality of the same movement direction around the base during operation, as long as at least The two transmissions may be rotated in the opposite direction of rotation about the base body, so that when the stone is mined, the stone can be provided with a shearing force to form a slit. In a preferred embodiment of the present application, the number of the transmission devices is specifically two. When the device is in operation, the two transmission devices have opposite movement directions, that is, one transmission device rotates clockwise around the base body, and the other transmission device Rotating counterclockwise around the base, such a cutting group can provide the rock with shearing force in two directions when working, and the two shearing forces are opposite in direction, and multiple cutting groups can work in parallel The formation of group shears is more conducive to cutting and forming slits for stone materials with higher strength and poor shear resistance.

For the grinding piece mounted on the side of the base body and protruding from the side of the base body, the grinding piece can be reciprocated in a predetermined direction on the base body, thereby rapidly grinding the cutting surface of the stone, which is still shown in FIG. For example, when the device is cut to the left in the direction shown in Figure 1, the entire circular cutting surface can be ground by reciprocating up and down. In the embodiment shown in Figure 1, the abrasive sheet is placed adjacent the edge of the substrate. This is a specific way of setting the grinding piece at the position of the base body, which can make the grinding piece have a larger grinding area. Of course, the grinding piece can also be mounted at other positions on the base body, and the shape of the grinding piece is not in the shape of a circular arc. Limited.

When the grinding disc can reciprocate in a predetermined direction on the base body, for the base body, the specific A dovetail groove 102 is provided on the base such that the refining plate 301 reciprocates in the longitudinal direction of the dovetail groove 102. The shape of the dovetail groove 102 and the grinding plate 301 on the base can be seen in FIGS. 11 to 13. When installing the grinding disc on the dovetail groove, the near-arc-shaped grinding piece as shown in FIG. 13 may be first inserted from one end of the dovetail groove 102, and then the above-mentioned grinding piece is continuously pushed forward until the length direction of the grinding piece is The length of the dovetail groove is completely coincident so that the plate is mounted on the substrate. The upper surface of the grinding blade 301 shown in Fig. 12 is attached to the bottom of the dovetail groove, and the grinding blade grinding head 302 is protruded from the side of the base body, thereby serving the purpose of grinding the cutting faces on both sides of the slit when the device moves forward. . When the grinding blade 301 reciprocates in the longitudinal direction of the dovetail groove 102, the lateral width of the grinding blade shown in Fig. 12 can be slightly smaller than the lateral width of the dovetail groove, so that the length of the grinding plate in the dovetail groove can be realized. Reciprocating motion.

When the grinding blade 301 reciprocates in the longitudinal direction of the dovetail groove 102, the grinding unit 300 further includes a lever connected to one end of the grinding plate, wherein the lever can reciprocate around the lever central axis 312 to drive the grinding plate Reciprocating in the longitudinal direction of the dovetail groove. It can be seen from FIG. 14 and FIG. 15 that the number of the grinding plates can be two on one side of the base body, so that two levers can be disposed here, that is, the first lever 310 and the second lever 311, the first dial The rod 310 and the second lever 311 respectively drive the two grinding discs. It should be noted that, as shown in FIG. 14 and FIG. 15, the two levers are separated from each other in a direction perpendicular to the illustrated direction, and the two levers are connected to the same lever center shaft 312, but only The length of one of the levers from the center axis 312 of the lever to the joint of the lever and the plate is greater than the length of the same position of the other lever, and the other shapes are equal in geometry. Referring to the schematic diagram of the grinding plate of Fig. 13, the grinding piece is connected to the shifting rod through the upper connecting hole 303 of the upper end of the grinding plate, and the "connection" here can directly connect the grinding piece with the shifting rod, and of course, the grinding piece shown in Fig. 15 It is indirectly connected to the lever through the connecting piece 313. The lever moves around the center axis 312 of the lever in a direction indicated by an arrow in FIG. 15 to drive the grinding plate to reciprocate up and down.

In addition, one end of the grinding disc is connected to the shifting rod, and the other end of the grinding disc can also be connected with an elastic member 320 which can be stretched or compressed. The elastic member 320 herein may be specifically a spring, and may of course be other elastic media. One end of the elastic member 320 is connected to the under-grain connection hole 304 of the above-mentioned plate, and the other end is mounted on the substrate as shown in FIGS. 16 and 17.

The lever reciprocates around the central axis 312 of the lever. When the lever applies a force to the blade, that is, the lever moves in the direction indicated by the upward arrow in FIG. 15, the blade is simultaneously driven, and the whole is in the dovetail slot. Moving upward, the elastic member 320 connected to the lower end of the grinding plate is forced to be stretched by the pulling force; when the lever is applied to the grinding blade When the force disappears, the elastic potential energy stored in the elastic member 320 is released, and the elastic member 320 pulls the grinding piece to move downward in the dovetail groove to return the grinding piece to the original position.

In order to improve the grinding effect on the stone, the grinding piece may further comprise a coarse grinding piece and a fine grinding piece. Referring to FIG. 15, the first rotating rod 310 drives the coarse grinding piece to reciprocate, and the second rotating rod 311 drives the fine grinding piece to reciprocate. Wherein the diameter of the abrasive grains on the rough grinding head is larger than the diameter of the abrasive grains on the fine grinding head grinding head, so that after the cutting head is cut into the front to form the slit, the rough grinding sheet first has a thick cutting surface on the side of the slit Grinding, forming a rough grinding surface, the fine grinding sheet continues to grind the rough grinding surface after the coarse grinding sheet, and finally forms a finely ground cutting surface. In this way, the cut surface is separately ground by the coarse grinding piece and the fine grinding piece, so that the grinding effect is better. In addition, the height value of the rough grinding piece protruding from the side portion of the base body is smaller than the height value of the portion of the fine grinding piece protruding from the side surface of the base body. Of course, the height value of the rough grinding piece protruding from the side portion of the base body is equal to the fine grinding piece protruding from the base body. The height value of the side portion is also possible, but the grinding effect is not as good as the above preferred solution.

The above-mentioned grinding sheet is disposed on one side of the base body to serve the purpose of grinding the stone material, and the above-mentioned coarse grinding piece and fine grinding piece may be respectively disposed on both sides of the base body, so as to grind the cutting surfaces on both sides of the kerf, and finally A finely ground cut surface is formed on both sides of the kerf. In one embodiment, when the grinding disc is disposed on both sides of the base body, that is, one side of the base body is provided with a rough grinding piece and a fine grinding piece, and at the same time, a rough grinding piece and a fine grinding piece are disposed at positions symmetrical on the other side of the base body. In addition, the grinding pieces which are symmetrically distributed on both sides of the base body may be connected together by rivets, so that the trajectory of the up-and-down reciprocating motion of the symmetrically distributed grinding pieces is kept uniform, and the grinding rivet holes 305 are provided on the grinding piece while being on the base body. A long hole penetrating the base body is provided so that the grinding piece on both sides of the base body simultaneously provides a movement space for the rivet when moving up and down.

In addition, the device inevitably generates noise during operation, so a muffling device can be provided on the device to reduce noise. Specifically, the muffler device can be disposed on the substrate. One achievable manner is to arrange a plurality of silencing holes 110 on the substrate, see FIG. According to the vibration frequency of the running vibration of the device, the plurality of silencing holes are arranged on the substrate to avoid resonance of the device. By providing a plurality of silencing holes 110 on the substrate, not only the noise can be reduced, but also the weight of the substrate and the entire device can be reduced. In addition, during the operation, the device generates a large amount of heat due to friction, so it is also possible to reduce the heat generated during the operation of the device by providing the heat dissipation holes 120 on the substrate. It should be noted that the number, size, shape, position or any combination of the sound absorbing holes and the heat dissipation holes herein are not limited to the illustration of the embodiment.

In order to serve the purpose of fixing a plurality of cutting groups, the above stone mining equipment may further comprise a chassis, The chassis and the base 100 are connected by a central shaft. The central axis hole 603 of the chassis on the chassis can be seen from FIG. 18. Referring back to the central shaft hole 130 on the base of FIG. 2, the central axis can be simultaneously passed through the chassis and the base. The central shaft hole connects the base body to the chassis, and the central axis here is not shown in the figure, so that the connection between the chassis and the base body serves as a fixed cutting group. In addition, a dust removing hole 600, a main power source heat dissipation hole 601, a chassis lifting hole 602, and the like may be disposed on the chassis. The dust removal hole is mainly provided to reduce the dust generated during the operation of the device, so as to achieve the purpose of cleaning work, the above-mentioned chassis lifting hole is arranged, thereby facilitating lifting the chassis and the cutting group connected to the chassis by borrowing other equipment.

It is also possible to mount a front pusher axle and a rear pusher axle on the chassis, see FIGS. 20 and 22, wherein the front pusher axle is mounted with a drive device 415, and the rear pusher axle is also mounted with a drive device 415, the drive device and the transmission device 201 mating drive unit mating connection. Both ends of the front push axle are connected to the chassis, and both ends of the rear push axle are connected to the chassis. An implementation manner is: the driving device is specifically a gear, and the driving unit matched with the transmission device 201 is also specifically a driving gear, and a plurality of gears are mounted on the front pushing axle, and a plurality of gears are also mounted on the rear pushing axle. The gear and the above-mentioned axle can be mounted by a keyway. The number of the plurality of gears is specifically determined by the number of the cutting unit 200. Through the above-mentioned installation and cooperation, the rotation of the wheel shaft drives the gear to rotate, the rotation of the gear drives the rotation of the driving gear, and the rotation of the driving gear finally drives the transmission device 201 to rotate around the base body 100.

It should be noted that the above-mentioned driving device is coupled with the driving unit, and the “mating connection” here may directly connect the gear and the driving gear as described in the above embodiments, and may also be other connection manners. When the drive unit is a drive gear, the main purpose is to achieve the coordinated speed, and finally the effect of the connection between the drive unit and the drive unit is also achieved.

It should also be noted that both the number of drives on the front push axle, the number of drives on the rear push axle, and the number of drive units should be the same as the cutting set, and the drive in a cutting set. The quantity is based. For example, one implementable method is that the entire stone mining equipment is equipped with a total of 20 cutting groups, and one cutting group has two transmissions with opposite rotation directions, so that 20 driving devices can be arranged on one front pushing axle. In cooperation with it, 20 driving devices are arranged on the wheel axle, and then a set of front pushing wheel shafts and rear pushing wheel shafts opposite to the direction of rotation of the front pushing wheel shaft are arranged, and 20 driving devices are respectively mounted on each of the tops, and finally two Front push axle, two rear push axles, a total of 80 drive units, 80 drive units, where the drive unit is specifically a drive gear. In addition, the interval between the driving devices, the interval between the driving units is also the interval between the cutting groups Based on. Of course, only one embodiment is schematically illustrated here. For the above-mentioned "all should be combined with the cutting group and the number of transmissions in one cutting group", it is of course also possible to drive a plurality of axially wide driving units. The cutting group is not limited by this application.

In order to drive the front pusher axle and the rear pusher axle, a front pusher wheel 412 can also be mounted on the front pusher axle, and a rear pusher wheel 413 can be mounted on the rear pusher axle to drive the pusher axle rotation by the pusher wheel rotation, see FIGS. 19 and 21. The front push wheel 412 is mounted at the axial end position of the front push wheel shaft, and the rear push wheel 413 is mounted at the axial end position of the rear push wheel shaft. Here, the axial end position may be selected from only one end of the shaft, or both ends of the shaft, wherein the shaft end position is not shown in FIG. 20 and FIG. It has been mentioned that the driving device on the front pusher axle and the rear pusher axle drives the drive unit. Therefore, the front pusher wheel can drive the front pusher axle to rotate. Similarly, the pushback wheel drives the rear axle to rotate, and the inference rotation finally ends. Drive the drive unit to work. The connection between the push wheel and the axle can be performed by a shaft keying. Here, the front push wheel and the rear push wheel are collectively referred to as a push wheel. Here, the front push wheel axle and the rear push wheel axle are collectively referred to as an axle.

In a previous preferred embodiment, it is mentioned that "the number of transmissions on one substrate is two, and the movement of the above two transmissions is opposite when the device is in operation", so that two sets of pushes with opposite movement directions can also be set here. The wheel, that is, the push wheel set shown in Fig. 19 and the push wheel set shown in Fig. 21 move in opposite directions, one set rotates clockwise and the other rotates counterclockwise. In addition, the rotation speeds of the two moving direction opposite transmissions are preferably equal, so as to achieve synergistic work for better cutting of stone materials, and further, because there is a certain interval between the cutting heads on the transmission device, The optimum cutting effect can be achieved by controlling the spacing between the cutting heads, increasing the number of cutting heads by reducing the spacing, or increasing the spacing to reduce the number of cutting heads.

In order to provide external driving force to the entire device, the device may further include a main power source 400, a speed reducer 402, a driving wheel 410, and a chassis. The main power source 400 is fixed on the chassis, and the main power source 400 may be a power device such as a motor or an internal combustion engine. In addition, the speed reducer 402 is connected to the power output shaft 401 of the main power source, and the driving wheel 410 is connected to the power output shaft 403 of the reducer. Also included may be a bearing support 404, a centrifugal clutch 405, etc., see in particular Figures 23 and 24. Through the above connection relationship, it can be seen that the main power source provides power to drive the main power source power output shaft to rotate, and the main power source power output shaft further drives the speed reducer to operate. Here, the speed reducer mainly plays the role of matching speed and transmitting torque. It can be a gear reducer, a worm reducer or a planetary gear reducer; it can also be a single or multi-stage reducer; It can be an expansion type, split flow or coaxial reducer, and the reducer is equipped with a reducer power output shaft. The power provided by the final main power source is transmitted to the power take-off shaft of the reducer, and the drive wheel is connected with the power output shaft of the reducer. Finally, the power provided by the main power source will drive the driving wheel to rotate.

In addition, the main power source is fixed on the chassis, and the fixing manner here may be bolt fixing or other fixing manner. In addition, the main power source generates heat during operation, so the main power source louver 601 can be disposed on the chassis to avoid heat accumulation. FIG. 18 schematically shows four symmetrically distributed main power source louvers. The small hole located between the cooling holes of the main power source is the main power source fixing hole, which is not shown in FIG.

In order to achieve the purpose of driving the front wheel and the rear wheel, the entire stone mining equipment may further include a transmission mechanism 414, as shown in FIGS. 19 and 21, such that the front push wheel 412 and the rear push wheel 413 pass through the transmission mechanism 414. The driving wheel 410 is connected, and an auxiliary tensioning wheel 411 can be added to tension and limit the movement of the transmission mechanism 414, so that the rotation of the reduction gear power output shaft 403 drives the driving wheel 410 to rotate, and the driving mechanism 414 can simultaneously drive the front pushing wheel. The 412 and the rear push wheel 413 rotate. The transmission mechanism here may be specifically a chain or a belt. When the transmission mechanism is a chain, teeth may be provided on the front push wheel 412, the rear push wheel 413, the drive wheel 410 and the tension wheel 411 to cooperate with the chain.

As can be seen in conjunction with Figures 19 and 21, although both of the push wheel sets shown in Figures 19 and 21 are coupled to one of the drive wheels 410, the two push wheel sets are coupled by the position of the drive mechanism and the push wheel. The direction of rotation is reversed. For example, when the driving wheel rotates in the clockwise direction, the push wheel set shown in Fig. 19 rotates counterclockwise, and the push wheel set shown in Fig. 21 rotates clockwise.

It has been mentioned that the movement of the lever drives the movement of the grinding plate. In order to power the lever, a lever cam shaft can also be provided. As shown in FIG. 25 and FIG. 26, a cam is mounted on the cam shaft of the lever, that is, the first cam 314, and The second cam 315 rotates around the lever cam shaft to drive the lever to reciprocate. The two ends of the lever cam shaft are connected to the chassis, and the chassis is not shown in the figure. It should be noted that the lever cam shaft for mounting the first cam and the lever cam shaft for mounting the second cam shown in FIG. 25 and FIG. 26 are mounted in different concentric axes, and the figure only shows schematically. The positional relationship between the two, so that the first cam and the second cam can rotate independently, the rotation speed does not affect each other, and the two lever cam shafts also rotate independently of each other, and are respectively driven by different driving devices installed at the shaft end. In addition, Figures 25 and 26 only schematically show two cams. In practical applications, the number of cams and the levers that cooperate with the cams should be based on the number of cutting groups and the number of plates on a cutting group. .

For the lever camshaft, a drive device 415 can also be mounted on the above-mentioned lever camshaft, and the different drive devices are connected to the drive wheel via different transmission mechanisms. In this way, the driving wheel rotation can indirectly drive the rotation of the different lever cam shafts, and the rotation speed of the different lever cam shafts can be adjusted by adjusting the wheel diameter of the driving device.

In order to make the whole stone mining equipment more stable, it is also possible to add a rack. See Figure 27 and Figure 28. The above rack and chassis can be connected through the central axis. See Figure 27 for the center axis hole 701 of the rack, the chassis and the central axis. Not marked in the middle. In addition, four rack lifting holes 702 can be placed around the top of the rack to facilitate lifting the rack, the chassis, and the cutting group connected to the chassis frame by borrowing other equipment.

In order to move the entire device, a leg 501 can also be mounted on the frame, see FIGS. 29 to 31. The lower end of the leg 501 has a walking wheel 502, so that the walking wheel 502 can walk on a preset track, and the leg can be installed. In the preset sleeve on the frame, and then fixed by bolts or screws, the legs can also be directly welded and fixed to the preset position of the frame. For the walking wheel at the lower end of the leg, an implementable manner is to mount the leg on the rotating shaft of the traveling wheel, so that the traveling wheel can roll forward on the preset track to drive the frame and the entire device to move. Another way to do this is to attach the legs directly to the walking wheel, the running wheel can be rotated, or it can remain relatively stationary with the legs without rotation.

In addition, a travel drive is mounted on the track, and the travel drive is used to drive the walking wheel and even the entire device. The stone mining equipment in the prior art, such as a combination saw, a circular saw, etc., can only mine a mining face with a slope of less than 25 degrees, and can not do anything for a mining face with a large slope. In this embodiment, the above-mentioned walking wheel, track, The travel drive, as well as the lifting of the mobile chassis and racks by other equipment, can directly mine slopes of 35 degrees, 45 degrees, or even 90 degrees and other difficult mining faces, greatly improving the application range of the equipment.

In order to protect the entire device, a cover 503 and a protective cover 504 can also be added on the outside of the device, as shown in FIG. 32, wherein the cover 503 is located outside the frame to protect the entire frame and the chassis, and the protective cover 504 is located. The outer side of the substrate mainly protects the substrate and the plurality of cutting groups. For the whole equipment, since most of the parts are made of metal, the working environment of the equipment is usually operated in the open air in the field. The external environment will inevitably affect the equipment. When the equipment stops working, it can be prevented by adding the above cover and protective cover. Rainwater erosion can also protect equipment during transportation.

In order to achieve a better cutting effect, the above device further comprises a vibration unit, which in turn can be subdivided into a driven wheel 801, a driven wheel shaft 802, a vibration connecting arm 803, a cam 804 and a vibrating arm connecting shaft 805, as shown in FIG. 33. And shown in FIG. 34, wherein the driven wheel 801 is mounted on the driven wheel shaft 802, the driven wheel 801 is coupled to the driving wheel 410 via a transmission mechanism 414, and the driven wheel shaft 802 is mounted with a cam 804, the upper end of the cam 804 and the vibrating connecting arm 803 The lower end of the vibration connecting arm 803 is mounted on the vibrating arm connecting shaft 805; both ends of the vibrating arm connecting shaft 805 are connected to the chassis and the frame. Thus, the driving wheel 410 rotates to drive the driven wheel 801 to rotate, the driven wheel 801 drives the driven wheel shaft 802 to rotate, and the cam 804 mounted on the driven wheel shaft 802 drives the vibration connecting arm 803 to move up and down with high frequency, because the lower end of the vibration connecting arm 803 is connected The vibrating arm is coupled to the shaft 805, and both ends of the vibrating arm connecting shaft 805 are connected to the chassis and the frame.
