A.

Known feed conveyors have a given angular position which is fixedly installed. The feed station of the feed conveyor is provided with a limiting surface that 'cuts' the thickness of the material layer transferred to the conveying conveyor belt when necessary to avoid excess capacity of the conveyor. Most simply, this confinement surface is a corresponding surface disposed on the conveyor belt in a manner that 'cuts' the opening or transverse boom or excess material. The material surface should be 'cut', especially when large batches of material are loaded into the feed station from a bucket, such as a wheel loader. The problem with this configuration is that the confinement surface is subjected to large forces and abrasion stresses, which may cause problems in the durability of the confinement surface. 'Cutting' the layer of material to an appropriate thickness by means of the limiting surface is achieved by a supply conveyor with sufficient power. The drive motors, power trains and conveyor belts of the feed conveyor are subject to great stress, which must be taken into account when dimensioning the components. In addition, known feed conveyors consume large amounts of energy to limit the thickness of the material layer to be conveyed, which naturally increases the operating cost of the feed conveyor.

It is an object of the present invention to provide a novel method of driving a feed conveyor, a feed conveyor and a shredder.

The method of the invention is characterized by monitoring the thickness of the material layer, and adjusting at least the slope of the inclination of the feed conveyor to adjust the thickness of the material layer.

In the conveyor of the present invention, the feed conveyor is connected to the carrier along one end of the at least one turning link and at the side of the feed station, the support member having at least one lifting device for adjusting the inclination of the inclination of the feed conveyor, The thickness of the material layer is characterized in that it is arranged to be adjusted by adjusting at least a part of the slope of the inclination.

In the shredder of the present invention, the feed conveyor is connected to the carrier at the conveyor end on the side of the feed station by a rotary link, the shredder of the feed conveyor on the side of the discharge station which adjusts the inclination of the feed conveyor with the inclination of the inclination with respect to the horizontal plane. One or more lifting devices for raising and lowering the ends, wherein the thickness of the material layer conveyed to the feed conveyor can be adjusted by varying the inclination of the inclination of the feed conveyor, the shredder lifting the feed conveyor in the longitudinal direction relative to the shredding unit. And at least one displacement device for displacing, wherein the position of the dropping point of the material flow falling from the feed opening of the shredding unit to the feed conveyor can be adjusted.

The second shredder of the present invention, the feed conveyor is connected to the carrier at the conveyor end on the side of the feed station by a rotary link, the shredder on the side of the discharge station which adjusts the inclination of the feed conveyor with the inclination of the inclination with respect to the horizontal plane. And at least one lifting device for raising and lowering the end of the feed conveyor, wherein the thickness of the material layer conveyed to the feed conveyor and the capacity of the conveyor can be adjusted by varying the slope of the inclination of the feed conveyor.

The idea of the present invention is that the thickness of the material layer conveyed to the feed conveyor is not limited by the mechanical limiting surface, but by adjusting the control parameters of the conveyor. By doing so, a material layer smaller than the shortest distance from the moving top surface of the conveyor belt to the closest fixed structure on the conveyor belt at the feed station is transferred to the feed conveyor. By adjusting the inclination of the inclination of the feed conveyor, it is possible to influence the thickness of the material layer batched on the conveyor belt at the feed station.

In an advantage of the present invention, the thickness control of the material layer does not apply any additional stress to the conveyor belt and power transmission device of the feed conveyor. Furthermore, no limiting surface is required to limit the thickness of the material layer. As a result, with the present invention, the load on the supply conveyor structure is smaller and the wear stress is smaller, which makes the supply conveyor more durable than before and reduces the need for maintenance. In addition, the energy consumption in the feed conveyor according to the invention can be clearly lower than in the case where the layer of material to be conveyed is cut by the mechanical confinement surface.

The idea of an embodiment of the present invention is to control the speed of the conveyor belt as well as the slope of the inclination to control the thickness of the material layer. By adjusting the inclination of the inclination and the speed of the belt, it can effectively affect the thickness of the material layer.

The idea of an embodiment of the invention is to adjust the speed of the belt and the inclination of the inclination to adjust the capacity of the feed conveyor. In this case, the capacity is adjusted based on the capacity of the shredder or other device following the feed conveyor. For example, the supply capacity required by the shredder may be determined based on the amount of material at the supply openings.

The idea of an embodiment of the present invention is to displace the feed conveyor in the longitudinal direction, to control the position of the material flow falling from the conveyor belt at the drop point at the discharge station and to adjust the position of the drop point.

The idea of an embodiment of the invention is that the feed conveyor comprises at least one measuring device for determining the thickness of the material layer being conveyed.

The idea of an embodiment of the present invention is that the shredding unit comprises a dropping station, and the position of the dropping station is preferably predetermined from the viewpoint of the operation of the shredding unit. In addition, at least one measuring device is arranged connected to the supply opening that determines the position of the dropping point of the material flow falling from the feed conveyor relative to the descent station. The operation of the feed conveyor can be controlled by a control unit arranged to adjust the feed conveyor in the longitudinal direction by a displacement device that sets the drop point at the determined dropping station.

The idea of an embodiment of the invention is that the feed conveyor has at least one lifting foot, by which the feeding conveyor can be driven from the transport position to the working position or vice versa. The lifting foot comprises a link mechanism, by which the discharge station of the feed conveyor is displaced from the transport position to the working position during upward displacement, while at the same time the entire conveyor is displaced longitudinally forward. In addition, by the action of the lifting foot, the discharging station of the feed conveyor is displaced from the working position to the transport position during the downward driving, and at the same time, the entire conveyor is displaced backward in length. Thereby, the discharge station of the conveyor can be driven upward of the shredding unit in the working position, and on the other hand, it can be driven laterally of the shredding unit in the transport position.

1 shows a shredder 1 which may comprise a movable carrier 2, a feed conveyor 3, a shredding unit 4 and a discharge conveyor 5. The feed conveyor 3 is used for transporting the material M to be treated, such as rock material, for example, into the feed opening 6 of the shredding unit 4, from which the shredding member breaks the material into smaller particle sizes. The material is conveyed toward (7). The shredding member 7 consists of an eccentrically rotating vertical shredding cone and a shredding chamber surrounding the cone, for example, whereby the treated material falls into a wedge space between the cone and the chamber and shreds into smaller particles. do. After the treatment, the material falls on the discharge conveyor 5 under the shredding unit 4, and the treated material can be transported, for example, into the pile 9 of the appropriate discharge site 8.

The feed conveyor 3 comprises two or more pulley drums 10, 11 on which a closed loop conveyor belt 12 is arranged. The at least one pulley drum 10 is a so-called drive pulley, which is rotated by the drive motor 13 and the required power transmission member around the longitudinal axis. The pulley drum 11 to which no rotational force is transmitted is a so-called return pulley, in which the conveyor belt 12 changes the moving direction. The drive pulley and the pulley drum may be arranged as shown in FIG. 1, or may optionally be arranged opposite to each other. In the upper part of the feed conveyor 3, the conveyance part 14 is provided, where the conveyor belt 12 advances in the conveying direction A. As shown in FIG. The return part 15 is provided in the lower part of the supply conveyor 3, where the conveyor belt 12 advances in the return direction B. As shown in FIG. The transport section 14 is provided with a supply station 16, and the conveyed material is supplied onto the movable upper surface of the conveyor belt 12. The material is discharged from the transport unit 14 in the discharge station 17. The feed station 16 may comprise a feed funnel 18, and the material to be conveyed may be fed into the feed funnel by, for example, another conveyor or wheel loader. The lower surface of the conveyor belt 12 can be supported by the plurality of support rolls 19 and the so-called impact bars in the transport portion 14.

In FIG. 1, the feed conveyor 3 is shown in the working position, in which the feed conveyor is provided with the conveyed material on the other hand such that the feed station 16 is preferably relatively low in terms of material supply. It is arranged inclined so as to fall from the discharge station 17 to the supply opening 6 located above the grinding unit 4. When the feed conveyor 3 is in the working position, the conveyor belt 12 in the conveying portion 14 has an inclination C of an uphill slope with respect to the horizontal plane. For example, the slope C of the uphill slope of the rock material is usually about 20 degrees. One or more lifting devices 20 can be arranged in connection with the feed conveyor 3, the slope C of the ascending slope being directed toward the end of the main body 21 of the feed conveyor 3 on the discharge station 17 side. It may be adjusted by moving to (D). The lifting device 20 may be, for example, a mechanical power member such as a suitable screw mechanism, or may be an actuator such as a pressure medium-driven actuator or an electronic actuator, for example. The end of the body 21 on the supply station 16 side may have one or more rotary links 22, and the feed conveyor 3 may be rotated about this link.

In addition, one or more displacement devices 23 can be arranged connected to the rotary link 22 to displace the feed conveyor 3 in the longitudinal direction. The longitudinal adjustment of the feed conveyor 3 affects the dropping point 24 of the material discharged from the conveyor as shown by the broken line in the figure. The shredding unit 4 may be provided with a predesigned lowering station in which the dropping point 24 is set in this position by displacing the feed conveyor 3. The lowering station can be preferably selected in view of the shredding treatment and durability of the shredding member 7. Most simply, the displacement device 23 is a mechanical power member such as a screw mechanism, an eccentric. On the other hand, the displacement device 23 may be, for example, a pressure medium drive actuator such as a hydraulic cylinder. The displacement device 23 may be arranged to move the rotary link 22, and alternatively, the main body 21 of the feed conveyor 3 is moved by the sliding mechanism 26 shown in FIGS. 3 and 4. It may be fixed to the rotary link 22, whereby a longitudinal movement E is made between the body 21 and the sliding mechanism 26.

The shredder 1 may comprise at least one control unit 27 which affects at least the operation of the feed conveyor 3. The control unit 27 may include a manual control member that affects the drive motor 13, the lifting device 20, and the displacement device 23. If the lifting device 20 and the displacement device 23 are mechanical power members, they are naturally adjusted manually without the control unit 27. On the other hand, the control unit 27 may be configured to automatically control the operation of the feed conveyor 3 according to the control strategy set for the feed conveyor. In this case, the control unit 27 may, for example, comprise programmable logic or a processor that executes a computer program to achieve the desired control action.

According to the concept of the present invention, the thickness P of the material layer 28 conveyed to the transport portion 14 is affected by adjusting at least the inclination C of the uphill slope of the feed conveyor 3. The thickness P of the material layer 28 may, for example, be adjusted to 300 to 400 mm. By increasing the slope C of the uphill slope, the thickness P of the material layer can be reduced, and on the other hand, the thickness P can be increased by decreasing the slope C of the uphill slope. The basic setting for the inclination C of the uphill slope of the feed conveyor 3 may be, for example, 20 °, and may be adjusted, for example, from 18 ° to 25 °. This is to ensure that the fixed surface 29 above the conveying portion 14 does not come into contact with the conveyed material layer 28, instead the thickness of the material layer 28 is controlled by adjusting the control parameters of the feed conveyor 3. Adjusted. The manner in which the conveyed material is batched on the conveyor belt 12 at the feed station 16 depends on, for example, the internal friction of the material, the friction between the conveyor belt 12 and the material and the environmental conditions. In addition to the slope C of the uphill slope, the speed V of the conveyor belt 12 can also be adjusted. If the conveyor is to be driven at a constant capacity, the following principles should be observed during control: The faster the speed V of the conveyor belt 12, the smaller the thickness of the material layer 28, and vice versa. Hold. As the drive motor 13, for example, a hydraulic motor can be used, and the rotational speed of the motor can be adjusted in a stepless manner.

2 shows the action associated with adjusting the thickness P of the material layer 28 to be transferred. The transport portion 14 of the feed conveyor 3 may be provided with one or more measuring devices 30, which can determine the thickness of the material layer 28 on the conveyor belt 12. For example, the operation of the measuring device 30 may be based on photocells, lasers, ultrasonic waves, and other non-contact measuring means may be applied to the measuring device. FIG. 2 shows that the measuring device includes a light emitter 30a for transmitting the light beam 31 to the feed conveyor 3 in the lateral direction, and a light receiver 30b for receiving the light beam 31. The light emitter 30a and the light receiver 30b may be disposed at a predetermined reference height, whereby the material layer 28 having a thickness P exceeding the reference height prevents the passage of light rays or the like. Based on the information, the slope C of the uphill slope can be increased to reduce the thickness of the material layer 28, and if necessary, the speed V of the conveyor can also be increased. If necessary, a plurality of measuring devices 30 may be used, and the measuring devices 30 may be arranged at two or more different reference heights, thereby allowing the thickness P of the material layer to be maintained between the upper and lower limits. do. Optionally, the measuring device 30 may be an apparatus 30c that measures the thickness of the material layer 28 and may be disposed, for example, on the structure 31 over the transport 14. For example, the measuring device 30c may be a laser distance measuring device, an ultrasonic radar, or the like. The measuring device 30 can be connected to the data transmission means 32, by which measurement data can be transmitted to the control unit 27. As described above, the control unit 27 may process the measurement data according to the control strategy imparted to the control unit, and also at least the supply conveyor (3) to control the operation of the lifting device 20 and the drive motor 13. The control parameters of 3) can be further adjusted.

Optionally, the operation of the feed conveyor 3 is controlled manually by the operator 33. The operator 33 can visually observe the thickness P of the material layer 28 on the transport portion, to adjust the lifting device 20 by the manual first control unit 27a and to control the manual second. The drive motor 13 may be adjusted by the unit 27b to adjust the thickness P of the desired material layer 28.

2 also shows the operation associated with the adjustment of the position of the dropping point 24. One or more measuring devices 34 may be provided in connection with the feed opening 6 of the shredding unit 4 to determine the location of the material flow descending from the discharge station 17. The shredding unit 4 may comprise a predesigned descent station 35, with the falling material flow preferably falling into the descent station in terms of the operation and durability of the device. In the case of a so-called gyratory or conical shredder, the descent station 35 may be located on the vertical axis of the shredder cone. The measuring device 34 is, for example, the light emitters 34a and 34c and the light receivers 34b and 34d to determine whether the drop point 24 is located between the limits 35a and 35b determined by the measuring device. It may also include. Alternatively, a measuring device 34e for measuring the position of the dropping point such as a laser distance measuring device, an ultrasonic radar or a non-contact measuring device, or the like may be used. The measurement data may be transmitted to the control unit 27 by the data transfer means 32, which may adjust the displacement device 23 according to the control strategy set in the control unit. The feed conveyor 3 may be displaced in the longitudinal direction such that the drop point 24 is at a desired point of the feed opening.

Optionally, the drop point 24 can be manually observed by the operator 33. The operator 33 can visually observe the position of the dropping point 24, and on the basis of this, the manual control unit 27c is used to adjust the mutual position of the feed conveyor 3 and the shredding unit 4. The displacement device 23 can be controlled.

The operator 33 can naturally inform the operator 33 of the measurement results of the measuring devices 30, 34 for observing the operation of the feed conveyor 3, and the operator can use the measurement data in the operation of the feed conveyor 3.

The processing capacity of the shredding unit 4 at each particular time can be determined by estimating the amount of material of the supply opening 6. The measuring device 34e may be arranged to measure the surface height, the thickness of the material layer, or optionally the operator may estimate the required material to be supplied to the crushing unit 4. On this basis, the capacity of the feed conveyor 3 can be adjusted, that is, the slope C and the belt speed of the uphill slope can be adjusted. Naturally, other methods of determining the necessity of supplying the material flow to the shredding unit 4 can also be used.

In FIG. 3, the feed conveyor 3 is in an inclined working position, and in FIG. 4, the feed conveyor is driven to a substantially horizontal transport position. The feed conveyor 3 may be supported by a part of the rear main body 2a of the carrier 2. The rear main body 2a may have a support 2b on which the feed conveyor 3 can be placed in the transport position. The end of the feed conveyor 3 on the discharge station 17 side may comprise a lifting foot 36 for displacement from the transport position to the working position and vice versa. One or more first lifting devices 37 are arranged connected to the lifting foot 36. The lifting foot 36 comprises a link mechanism and, when driven from the transport position to the drive position, the discharge station 17 is displaced upwards, while at the same time the entire conveyor is displaced forwards towards the shredding unit 4. 3 is displaced to different positions by the link mechanism. In this way, it is possible to drive the discharge station 17 above the supply opening 6. When the feed conveyor 3 is displaced in the carrier 2 from the working position to the transport position, the discharge station 17 of the conveyor is displaced downward, and at the same time the entire conveyor is displaced rearward. The displacement device 23 is disconnected during the time when the conveyor 3 is driven to a different position. For example, in the case of a mechanical displacement device 23 such as a turnbuckle screw shown in FIGS. 3 and 4, the device can be disconnected during displacement and reconnected when the conveyor is driven to the working position. . Thus, the feed conveyor 3 can move in the longitudinal direction during the displacement by the sliding mechanism 26 between the carrier 2 and the conveyor body 21. On the other hand, the displacement device 23 can be configured to enable longitudinal movement of the conveyor during displacement. As shown in FIG. 4, the lifting foot 36 may be bent under the feed conveyor 3 in the transport position because of the link system of the lifting foot. The first lifting device 37 in connection with the lifting foot 36 may be used only for the displacement between the transport position and the working position, and optionally, in some cases, to adjust the slope C of the uphill slope. . However, the lifting foot 36 may be provided with a tilt adjusting mechanism 38, which may include one or more second lifting devices 39 for adjusting the tilt C of the uphill slope. The operation and structure of the lifting foot 36 is described in detail with respect to FIGS. 5 to 9.

Feed station 16 may include one or more feed supports 40 that include one or more beams disposed away from the conveyor belt. Feed support 40 may comprise one or more conveyor longitudinal beams and one or more transverse beams. The feed support 40 can support a portion of the load of the material of the feed station 16 and can facilitate the batching performed in the feed station 16.

5 shows only the lifting foot 36 in a position corresponding to the working position for simplicity, and FIG. 6 shows a lifting foot in a position corresponding to the transport position. The lifting foot 36 may include a rotating beam 41 whose first end is connected to the support 43 or the carrier 2 by a first link 42. The carrier is optionally indicated by the broken line in FIG. 5. In addition, the second end of the rotating beam 41 includes a second link 44, which may be connected to the first end of the support arm 45 belonging to the tilt adjusting mechanism 38. The second end of the support arm 45 may be connected by a third link 46 to the body of the feed conveyor. In addition, the second lifting device 39 is connected to the first end portion of the support arm 45. This lifting foot 36 may be arranged on both sides of the feed conveyor. The lifting foot 36 may be interconnected with the transverse support 47. The first lifting device 37 may be connected to the lateral support 47 so that the lifting foot 36 can be driven by one common lifting device 37.

The first link 42 of the rotating beam 41 is preferably arranged at the height of the feed conveyor, for example when in the transport position by the vertical support 43. In this case, the rotating beam 41, the transverse support 47 and the tilt adjustment mechanism 38 can rotate between the feed conveyor and the carrier. Thus, in the transport position, the feed conveyor is relatively flat, thereby enabling conventional road transport.

In Fig. 7, the lifting foot 36 is driven to the upper position, and the second lifting device 39, preferably the hydraulic cylinder, on both sides of the feed conveyor is driven to the upper position to adjust the slope C of the uphill slope. It is. When the second lifting device 39 is used, the support arm 45 can rotate relative to the links 44, 46. In FIG. 8, the second lifting device 39 is driven to its lowest position. In this case, the slope C of the uphill slope is adjusted only by the second lifting device 39.

9 shows the transverse support 47, whereby the rotating beams 41 of the lifting foot on different sides of the conveyor are interconnected. The first lifting device 37 is connected to the lateral beam 49 by a first fixed lug 48a and a second fixed lug 48b. In this case, one first lifting device 37 is sufficient to move both lifting feet 36. Naturally, more first lifting devices 37 can be used. The stationary lugs 48a, 48b can be rotatably connected to each other by a link 50. When the feed conveyor is displaced in the longitudinal direction, the fixing lugs 48a and 48b can move relative to each other. At the same time, the second fixing lug 48b can rotate around the link 51 at the fixing point of the lifting device 37. When the conveyor is displaced to the right in FIG. 9 by the displacement device 23, the second fixing lug 48b rotates clockwise in the direction G in the drawing, which in the drawing direction of the discharge station of the feed conveyor Enable displacement. Thus, the lifting foot 36 rotates relative to the link 43 and the discharge station is displaced forward and upward at the same time. The magnitude of the upward displacement is influenced by the dimensions of the lug 48. In the series of cases described above, the lifting device 37 is not used. In the position shown in FIG. 9, the second fixing lug 48b opposes the lower surface of the transverse beam 49, thereby lifting device 37 for rotation of the lifting foot 36 relative to the link 43. Force can be transmitted to the transverse beam 49. In the situation shown in FIG. 9, even if the fixing lug 48b is affected by the force of the lifting device 37, this fixing lug cannot rotate counterclockwise.

For safety reasons, the supply station of the feed conveyor according to the invention may be provided with an opening, a boom or similar means for restricting the supply of material. However, limiting means are used only in special cases related to conveyor malfunctions and failures.

In some cases, the features presented in the present invention may be used by themselves regardless of other features. On the other hand, if necessary, the features described in the present invention may be combined in various combinations.

The drawings and their associated descriptions are intended only to illustrate the spirit of the invention. The detailed description of the invention may be modified within the scope of the claims.
