Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a large dust box installed in an urban area or housing complex.

[0002]

[Prior Art]

 In the one-point hanging type dust box, it is necessary to open and close the lower lid directly by operating the handle lever, and it is also necessary to eliminate the disadvantage that dust is accumulated in one direction. Therefore, as shown in Japanese Utility Model Publication No. 53-31668, for example, the lower lid can be opened / closed from the passenger compartment of the garbage collection vehicle, and the lower lid is opened / closed from the center by a double door, so that the dust A three-point suspension type dust box that can average and accumulate the items has already been devised.

This conventional three-point hanging dust box will be described with reference to FIG. The main body 1 of the dust box is provided with one main suspension ring 2 provided on the upper part and two suspension upper and lower members 3 provided on both side surfaces of the main body 1 of the dust box. The suspending / lowering member 3 includes an auxiliary suspending wheel 4 and a sliding member 5 to which the auxiliary suspending wheel 4 is fixed.

One end of each of the pulling rods 6a and 6b is rotatably connected to the sliding member 5, and the other end of each of the drafting rods 6a and 6b is a blanket projecting from a side surface of the lower lids 7a and 7b. It is connected to 8a and 8b. Reference numerals 9a and 9b denote hinge portions that connect the dust box body 1 and the lower lids 7a and 7b to each other, and enable opening and closing of the lower lids 7a and 7b, and 10a and 10b are feet of the dust box.

Inserting lids 13a and 13b are formed so as to be openable and closable via hinges 12a and 12b provided on the upper part of the dust box body 1, and dust introduced by opening the inserting lids 13a and 13b is lower lid 7a. , 7b.

When collecting dust from the dust box, the dust box is lifted by a crane or the like at three points of the main suspension wheel 2 and the auxiliary suspension wheels 4 on both sides, and the dust is collected on the dust collection chamber of the garbage truck. If only the auxiliary suspension wheel 4 is separated, the suspension up-and-down member 3 slides on the guide rail 14 and moves downward, so that the lower lids 7a and 7b are opened with the hinge portions 9a and 9b as fulcrums, and the dust collected inside is lowered. Are dumped.

[0007]

[Problems to be solved by the device]

 However, the garbage truck that collects dust from the three-point suspension type dust box must be a large vehicle of 4 tons or more. Therefore, a garbage truck for three-point suspension type can be installed in a narrow road. Since it is not possible, single-point hanging dust boxes are still used.

Therefore, since the structure of the garbage truck for the three-point hanging type dust box and the garbage truck for the one-point hanging type dust box is different, each municipality has a cleaning vehicle for the one-point hanging type. Since it has to be used together with a three-point hanging type garbage truck, there is a drawback in having more garbage trucks than necessary.

[0009] In addition, when a single-point hanging type garbage truck carries out a garbage collecting activity, even if there is a three-point hanging type dust box in the middle of the collection, it is not possible to collect it. There was also the drawback that it was inefficient because the collection vehicle had to be sent to the same place, and it was troublesome twice.

Therefore, the present invention makes it possible to collect dust even with a three-point hanging type dust box or a single-point hanging garbage truck, thereby reducing the number of garbage trucks coexisting in each municipality. The purpose is to provide a dust box that enables efficient garbage collection activities.

[0011]

[Means for Solving the Problems] However, the gist of the present invention is to provide a main suspension ring on the upper part of the dust box body and a lower part on the lower end of the dust box body for opening and closing the dust thrown in through the dust input port. In a dust box that opens with a lid and is dumped to the outside, a lifting and lowering member having an auxiliary suspending ring that slides up and down through guide rails provided on both sides of the dust box body, and one end of the lifting and lowering member. A first lower lid opening / closing device having a tow bar connected to the lower lid and the other end connected to the lower lid, a handle lever rotatably attached to the dust box body, and a relay lever attached to the handle lever. A crank connected through the shaft, a shaft fixed to the side surface of the dust box body so as to rotate together with the crank, and integrally rotated with the shaft, The serial lower lid is to have a lower lid closing device second constituted by a lockable rotation lock so that the closing stop.

[0012]

[Action]

 Therefore, in this invention, when the dust is collected using the single-point hanging type garbage truck, the handle lever of the second lower lid opening / closing device is operated in advance and the lower lid of the dust box is rotated by the rotation lock. The main suspension ring on the top of the dust box is hooked on a crane to lift it, and the handle lever is operated on the dust collection chamber of the garbage collection vehicle to remove the rotation lock from the lower lid. Open the lower lid and discard the trash.

Further, when collecting dust using a three-point suspension type garbage truck, the handle lever of the second lower lid opening / closing device is operated in advance to rotate the rotation lock from the lower lid. After removing it, hook the main suspension ring and the auxiliary suspension ring on a crane to lift them up, remove the auxiliary suspension ring on the garbage collection chamber of the garbage truck as before, open the lower lid, and discard the dust.

Therefore, even a single-point hanging type garbage collection vehicle can collect dust from the three-point hanging type dust box, so that a three-point hanging type garbage collecting vehicle is not required to the left. It is possible to reduce the number of combined use of the point suspension type garbage truck and the single point suspension type garbage truck.

[0015] Furthermore, since it is possible to prevent the single-point suspension type garbage collection vehicle and the three-point suspension type garbage collection vehicle from carrying out the garbage collection activities through the same route, it is possible to reduce the number of garbage collection vehicles. You can save time and effort and collect garbage efficiently.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. However, since the points that overlap with the above-mentioned conventional technology have already been described in detail, the same symbols will be attached and the explanation thereof will be omitted, and only the important points will be explained.

FIG. 1 and FIG. 2 show a dust box according to an embodiment of the present invention. In the dust box, the lifting and lowering member 3 having the auxiliary hanging wheels 4 provided on opposite side surfaces 32a is provided. A first lower lid opening / closing device 15 including the tow bars 6a and 6b, and a second lower lid opening / closing device 31, which is a feature of the present invention, are provided.

The second lower lid opening / closing device 31 has a manually-operated convex handle lever 16, and the handle lever 16 is provided on a flange portion 33b of the side surface 32b adjacent to the side surface 32a. It is fixed to the lever fixture 17 with a pin 18 so that a slight gap is formed. The handle lever fixture 17 is provided so as to stand upright between the handle lever 16 and the side surface 32b, and the handle lever 16 is several tens of degrees with respect to the handle lever fixture 17 with the pin 18 as a fulcrum. It is possible to rotate at an angle of.

A switching device 19 for switching the dust box between the three-point suspension type and the one-point suspension type is provided between the handle lever 16 and the handle lever fixing device 17. Will be described later.

One end of the relay lever 21 is bent from the inside and locked in a laterally extending slot 20 provided at a predetermined position above the pin 18 of the handle lever 16. The other end of the relay lever 21 is fixed so as to be bent from the inside to pass through a hole 23 provided at an upper portion of a crank 22 provided at a corner of the dust box body 1.

A hole 24 is provided in the lower portion of the crank 22, and a shaft 25 is firmly inserted into the hole 24. The shaft 25 has an L-shaped fixing member 26 attached to a corner portion of the flange portion and an L-shaped attachment portion that is attached to the flange portion 33 a on the lower side surface where the auxiliary suspension ring 4 is provided so as to contradict each other. The fixing members 27 and 28 are fixed inside the tow rod 6a, but the fixing members 26 and 28 are rotatable because they are slightly relaxed.

Between the fixture 27 and the fixture 28, a key claw-shaped rotation lock 29 is fixed so as to rotate integrally with the shaft 25, and the rotation lock 29 and the rotation lock 29 are attached to the lower lid 7a. The protrusions 30 are formed so as to mesh with each other. As a result, the tip portion of the rotary lock 29 is locked to the lower lid 7a and the lower lid can be prevented from being opened.

Further, in the downward direction of the lower lid 7a locked by the rotation lock 29, there is provided a mating surface correction foot 11 which has a substantially arcuate shape with a predetermined width, and the bulging portion of which is in contact with the ground. A part of the mating surface correction foot 11 is adapted to be applied to the lower lid 7b at the time of grounding. Accordingly, at the time of grounding, the lower lid 7b is prevented from being opened not only by the pulling rod 6 but also by the mating surface correction foot 11, so that a small dust in the dust box or waste water of the dust can be removed from the lower lid 7b. It is possible to further prevent the leak from coming out.

However, when the handle lever 16 is rotated in the direction of the arrow, the relay lever 21 and the crank 22 also move in the same direction as shown in FIG. 3, and the shaft 25 also rotates accordingly. Also rotates in the direction of the arrow in accordance with the rotation of the shaft 25, so that the lock is released and the lower lid 7a is opened. On the other hand, since the handle lever 16 is provided with a spring (not shown), when the hand is released from the handle lever 16, the handle lever 16 automatically returns to the original position, and again by the rotation lock 29, the lower lid 7a. Is locked.

A relay lever extending in the opposite direction to the relay lever 21 is symmetrically attached to the handle lever 16 with respect to the pin 18, and the opening / closing mechanism is also provided on the side surface having an auxiliary suspension ring on the opposite side. Although they are provided in the same manner, the structure thereof is the same, so the description thereof will be omitted. Further, the shape of the handle lever or the like is not limited as long as it can exhibit its function.

From the above, when collecting dust with a single-point hanging type garbage truck, the second lower lid opening / closing device 31 is provided even if only the main suspension wheel 2 of the dust box is lifted by a crane or the like. Immediately after the lower lid 6a is not opened, the dust can be dumped by moving the handle lever 16 on the dust collection chamber of the garbage truck.

However, when collecting garbage with a three-point hanging type garbage collection vehicle, if the garbage is dumped by the handle lever 16 on the garbage collection box or the like each time during the collection work, It becomes complicated, and the advantage of being able to operate it from the cabin of the garbage truck of the three-point suspended dust box is lost.

Therefore, when collecting dust with a three-point hanging type garbage truck, the switching tool 19 is used. The switching tool 19 is supported near the lower end corner of the handle lever 16 so as to allow the distance from the handle lever fixing tool 17 to be changed, and is located between the handle lever 16 and the handle lever fixing tool 17. The handle lever 16 blocks the movement in the axial direction during the operation. Only when the handle lever is tilted at a predetermined angle, the handle lever 16 does not block the handle lever 16 and The distance can be extended.

Therefore, when the handle lever 16 is rotated a predetermined angle from the state shown by the solid line in FIG. 3 and the switching tool 19 is pulled toward you, the handle lever 16 is moved by the switching tool 19 as shown in FIG. It is locked so that it does not return to its original state at the position indicated by the broken line in Figure 3, and the closed state of the lower lid by the rotary lock 30 remains released. Like the normal three-point suspension dust box, three-point suspension The garbage can be dumped simply by operating it from the passenger compartment of the garbage truck for ceremony. On the contrary, when the handle lever 16 is locked and the switching tool 19 is pushed, the lock of the handle lever 16 is released, and the handle lever 16 functions as a one-point hanging dust box.

[0030]

[Effect of the device]

 As described above, according to the present invention, even a single-point hanging type garbage truck can collect dust from the three-point hanging type dust box, so that the three-point hanging type garbage truck can be used. Even though there is a single-point hanging type garbage truck, it is not necessary to purchase a new one, and a three-point hanging type garbage truck and a single-point hanging type garbage truck are more than necessary. The combined use can be reduced.

Further, according to this invention, the single-point hanging type garbage collecting vehicle and the three-point hanging type garbage collecting vehicle do not have to carry out the garbage collecting activity through the same route, and It is possible to prevent the trouble of collecting the waste twice and to collect the waste efficiently.
