Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, in particular to a material pushing device for a self-loading and unloading garbage truck. Background Art

[0002] Garbage trucks are an indispensable part of urban garbage cleaning. A garbage truck generally includes a chassis and a carriage located on the chassis. A garbage inlet and a trash can lifting and dumping mechanism are arranged at the tail of the carriage. The trash can lifting and dumping mechanism is used to lift the trash can filled with garbage above the carriage, and then pour the garbage into the open garbage inlet.

[0003] Since the garbage contains a certain amount of relatively large compressible garbage, this type of garbage will occupy a large amount of the carriage volume in the expanded state;

[0004] On the other hand, when feeding the garbage, most of the garbage will accumulate at the garbage inlet and will not actively enter the inner layer of the carriage. To avoid this situation, a baffle is usually installed at the feeding port to push down the crowded garbage. To prevent the garbage from spilling during transportation, the upper end of the carriage including the garbage inlet is in a closed state;

[0005] Due to the interference of the upper end closing plate of the carriage, the movable stroke of most baffles extending into the carriage is short, and the garbage cannot be directly pushed to the other end of the carriage, resulting in the ineffective use of the space at the end of the carriage far from the feeding port and a small loading capacity.

[0006] Aiming at the problems existing in the above-mentioned prior art, the utility model designs and manufactures a material pushing device for a self-loading and unloading garbage truck to overcome the above defects. Utility Model Content

[0011] Both ends of the extension plate are respectively provided with a lower connecting block and an upper connecting block that cooperate with the upper hook block and the lower hook block. When the lower hook block abuts against the upper connecting block, the sliding plate and the extension plate can be linked, and when the upper hook block cooperates with the lower connecting block, the movement of the extension plate can be limited.

[0012] Preferably, the material pushing component includes a push plate and two hydraulic cylinders. One end of the push plate is hinged to the sliding plate, and both ends of the hydraulic cylinder are respectively hinged to the sliding plate and the push plate, and the hydraulic cylinder can control the rotation of the push plate.

[0013] Preferably, a plurality of raking teeth are installed at one end of the push plate that is not hinged to the sliding plate.

[0014] Preferably, the raking teeth are detachably installed on the push plate.

A sliding seat that cooperates with the reciprocating lead screw is installed on the slider 17 close to the reciprocating lead screw side. Installing it on the side wall can prevent the reciprocating lead screw from blocking the feeding port 15 and interfering with the dumping of garbage, and can also extend the stroke of the sliding plate 5 to the greatest extent;

[0030] A fixed plate 3 is installed at one end of the feeding port 15 of the utility model, and the fixed plate 3 is located below the sliding plate 5. An extension plate 4 is slidably installed on the inner wall of the compartment 1, and the extension plate 4 is located between the fixed plate 3 and the sliding plate 5. One end of the fixed plate 3 is fixed to the compartment 1, and the other end of the fixed plate 3 is provided with an upper hook block 12, and one end of the sliding plate 5 is provided with a lower hook block 11;

[0031] Specifically, the two ends of the extension plate 4 are respectively provided with a lower connecting block 13 and an upper connecting block 10 that cooperate with the upper hook block 12 and the lower hook block 11. The abutment between the lower hook block 11 and the upper connecting block 10 can enable the sliding plate 5 to be linked with the extension plate 4, and the cooperation between the upper hook block 12 and the lower connecting block 13 can limit the movement of the extension plate 4.

[0032] Specifically, a guide plate 9 inclined downward along the direction of the fixed plate 3 is provided at the end of the feeding port 15 away from the fixed plate 3. When garbage is dumped into the compartment 1 from one end of the guide plate 9, part of the garbage will slide toward the end of the compartment 1 close to the fixed plate 3 due to its own gravity, which can prevent garbage from piling up.

[0033] A material-pickup assembly is installed at the other end of the sliding plate 5 of the utility model. When the upper hook block 12 and the lower connecting block 13, the lower hook block 11 and the upper connecting block 10 are all abutted, the material-pickup assembly can be buckled on the upper end of the guide plate 9, and the fixed plate 3, the extension plate 4, the sliding plate 5 and the material-pickup assembly can close the entire feeding port 15 to prevent garbage from falling during transportation and causing pollution to the environment.

[0034] Specifically, a limiting rod 2 is provided at the connection between the fixed plate 3 and the body 1, and the limiting rod 2 can limit the sliding plate 5 and the extension plate 4 to prevent the extension plate 4 from falling out of the connection between the fixed plate 3 and the body 1.

[0035] A support rod 14 is installed inside the car body 1 of the utility model, which is against the lower end surface of the fixed plate 3. The support rod 14 is located between the limit rod 2 and the upper hook block 12. Both ends of the limit rod 2 and the upper hook block 12 are fixed to the car body 1, which plays the role of fixing and supporting the fixed plate 3. At the same time, the two side plates of the car body 1 can be connected as a whole to improve the overall strength of the car body 1.

[0036] The material shifting assembly of the utility model comprises a shifting plate 7 and two hydraulic cylinders 6, one end of the shifting plate 7 is hinged on the sliding plate 5, and the two ends of the hydraulic cylinder 6 are respectively hinged on the sliding plate 5 and the shifting plate 7, and the hydraulic cylinder 6 can control the rotation of the shifting plate 7. When there is a lot of garbage piled on one end of the guide plate 9 of the compartment 1, the hydraulic cylinder 6 controls the shifting plate 7 to rotate and contact the garbage, and the motor controls the sliding plate 5 to slide. During the sliding process, the shifting plate 7 pushes the garbage toward the end of the compartment 1 away from the guide plate 9, and gradually pushes the garbage to the end of the compartment 1 for compression, thereby improving the space utilization rate and the loading capacity, and indirectly reducing the transportation cost.

[0037] One end of the shifting board 7 of the utility model, which is not hinged to the sliding board 5, is provided with a plurality of raking teeth 8. The raking teeth 8 are detachably mounted on the shifting board 7, and whether to install the raking teeth 8 is selected according to different working environments.

[0038] Specific working process

[0039] First step, the motor rotates to control the sliding board 5 to move away from the guide board 9. At the same time, the hydraulic cylinder 6 shortens to control the shifting board 7 to rotate upward, opening the closed feeding port 15 to avoid interference with the dumping of garbage.

[0040] Second step, after the garbage is dumped, the hydraulic cylinder 6 extends to control the shifting board 7 to rotate downward so that the shifting board 7 contacts the garbage. At the same time, the motor rotates again to control the sliding board 5 to slide towards the fixed board 3, and the garbage also moves along with the pushing of the shifting board 7.

[0041] Third step, the hinged ends of the sliding board 5 and the shifting board 7 are flush with one end of the fixed board 3 close to the guide board 9, and the motor stops rotating. At this time, the garbage has been pushed by the shifting board 7 to one end of the box body 1 away from the guide board 9 and is pressed against the inner wall of the box body 1 for compression.

[0042] Fourth step, the hydraulic cylinder 6 shortens to make the shifting board 7 rotate upward to reset. At this time, garbage can also be dumped towards the guide board 9 again. After the garbage is dumped, the motor rotates again to control the sliding board 5 to move back to its original position.

[0043] Fifth step, repeat the above second, third, and fourth steps until the inside of the box body 1 is filled, making effective use of the space inside the box. Without changing the volume of the box body 1, the transportation volume is increased.

[0044] Fifth step, the motor rotates to control the sliding board 5 to move towards the guide board 9 until the upper hook block 12 and the lower connection block 13, and the lower hook block 11 and the upper connection block 10 are in contact with each other for limiting, and then the motor stops rotating. At this time, the hydraulic cylinder 6 extends to make the shifting board 7 rotate downward and buckle on the upper end of the guide board 9. The fixed board 3, the extension board 4, the moving board and the shifting board 7 close the feeding port 15 of the box body 1, which can avoid garbage spilling out and polluting the environment during transportation.
