Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary structures of garbage trucks, in particular to a lifting and dumping structure of a garbage truck. Background Art

[0002] Garbage trucks are core equipment for urban solid waste transportation, and the efficiency of their loading process directly impacts overall operational effectiveness. In current mainstream systems, trash cans are primarily emptied through chain-type or hook-type lifting mechanisms. This requires sanitation workers to manually drag or push the trash cans to fixed lifting points on the side of the vehicle, attach or position them, and then activate the lifting mechanism. This process requires workers to frequently move back and forth between the trash can's parking spot and the vehicle, performing heavy lifting and handling. This is labor-intensive and creates a harsh working environment. Furthermore, due to the mechanical characteristics of traditional lifting mechanisms (such as chain tracks or hook constraints), the trash cans can typically only reach a certain tilt angle (e.g., 45°-70°) during lifting and dumping, making it difficult to achieve a near-vertical dumping position (e.g., above 85°). This prevents adherent waste (such as wet and compressed waste) remaining on the bottom or walls of the bin from being completely emptied, resulting in waste stagnation, odor generation, and even impacting the bin's subsequent use.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 7 As shown, a garbage truck lifting and dumping structure of the present invention includes a base 1, an active arm and a driven arm 8. A main shaft 2 is rotatably provided on the base 1, and a power wheel 3 is fixed on the main shaft 2. The active arm includes two side arms 4 arranged opposite to each other and a plurality of connecting columns 5 connecting the two side arms 4. One end of each side arm 4 is mounted on the main shaft 2. An arc-shaped opening 6 coaxial with the main shaft 2 is opened on the side arm 4 close to the base 1, and an adjusting arm 7 is inserted into the arc-shaped opening 6. One end of the driven arm 8 is rotatably connected to the other end of the two side arms 4. A clamping unit 11 is provided at the other end of the driven arm 8. A mutually parallel auxiliary arm 1 9 is provided on the driven arm 8 and the adjusting arm 7. The two auxiliary arms 1 9 are rotatably connected via an auxiliary arm 2 10. In the present invention, in order to save space, the dumping structure is generally installed between the front of the garbage truck and the truck bed, so that the overall structure will not take up a large space on the side of the garbage truck, reducing the width of the garbage truck; the base 1 can be fixed to the garbage truck by bolts, and the main shaft 2 provides support for the active arm and the driven arm 8. Since the main shaft 2 needs to rotate, the power wheel 3 can be connected to provide power for the main shaft 2. Specifically, a power structure such as a motor can be set on the base 1, and the power structure is used to drive the power wheel 3 to rotate, thereby driving the active arm to rotate; the arrangement of the arms 4 on both sides can provide installation space for the auxiliary arm 9 and the auxiliary arm 2 10, so that the auxiliary arm 9 and the auxiliary arm 2 10 are hidden Between the two side arms 4, and this structural mode of the two side arms 4 can reduce the weight of the active arm, thereby reducing the weight of the overall structure; a number of connecting columns 5 connect and fix the two side arms 4, and the connection mode of the connecting column 5 and the side arm 4 can be through bolts, welding, clamping, etc.; the arc-shaped opening 6 can provide an insertion space for the adjustment arm 7, and because the active arm and the main shaft 2 need to rotate, the adjustment arm 7 can move within a specified angular range along the circumference of the main shaft 2 within the arc-shaped opening 6, so that it can provide a connection position for the connection between the main shaft 2 and the side arm 4, and provide a support space for the adjustment arm 7, and also allow the main shaft 2 and the adjustment arm 7 to move relative to each other; It should be pointed out that the active arm and the driven arm 8 can form a curved arm structure to facilitate supporting the clamping unit 11 and carrying the clamping unit 11 for movement; by using the arrangement of the two auxiliary arms 19 and the auxiliary arm 2 10, a parallelogram structure can be formed. When the main shaft 2 rotates, the auxiliary arm 19 and the auxiliary arm 2 10 can guide the driven arm 8 so that the direction of the driven arm 8 remains unchanged and it performs translational movement. When the adjusting arm 7 actively moves circumferentially around the main shaft 2 in the arc-shaped opening 6, the auxiliary arm 2 10 will pull the driven arm 8 to move. When the adjusting arm 7 rotates synchronously with the main shaft 2, the driven arm 8 performs circular movement. Therefore, by controlling the movement mode and movement timing of the adjusting arm 7, the driven arm 8 can be controlled in multiple forms of movement. When in use, the active arm and the driven arm 8 are bent and retracted in the space between the bucket and the front of the garbage truck. When the garbage truck travels to the designated position, the main shaft 2 and the power wheel 3 are rotated, and the adjusting arm 7 is stationary. At this time, the active arm drives the driven arm 8 to extend outward, and the driven arm 8 performs a translational movement, thereby causing the clamping unit 11 to translate to the position of the garbage bin and clamp the garbage bin. After that, the main shaft 2 continues to rotate, and the adjusting arm 7 moves synchronously with the main shaft 2. At this time, the driven arm 8 is relatively stationary with the active arm, that is, the driven arm 8 rotates synchronously with the main shaft 2. The driven arm 8 uses the clamping unit 11 to carry the trash can in an arc motion, thereby lifting the trash can above the front of the vehicle and flipping the direction of the trash can so that the opening of the trash can faces downward to facilitate the garbage to fall into the truck bucket; during the process of dumping the garbage, the driven arm 8 can be moved relative to the active arm by controlling the adjusting arm 7 to be stationary or in motion, thereby causing the trash can to vibrate and facilitate the removal of garbage from the trash can; since the adjusting arm 7 and the main shaft 2 have multiple movement modes, a separate power source can be set for the adjusting arm 7; By adopting a rotary lifting method to lift the garbage bin above the truck bed, the dumping angle of the garbage bin can be arbitrarily controlled, which facilitates the falling of garbage and avoids the restriction of the falling of garbage due to the small dumping angle of the garbage bin; by adopting a crank arm structure composed of an active arm and a driven arm 8, the structure can be conveniently folded and hidden between the truck bed and the front of the garbage truck, thereby reducing the width of the garbage truck; by adopting a grabbing and dumping method, there is no need for workers to move the garbage bin to a designated location, thereby saving manpower and avoiding workers from contacting the garbage bin for a long time.

[0019] Furthermore, the base 1 is provided with an arc-shaped chute 12 coaxial with the main shaft 2, and a slider 13 is slidably provided in the arc-shaped chute 12, and the slider 13 moves within a prescribed stroke. The adjustment arm 7 is fixedly connected to the slider 13, and the slider 13 is connected to the base 1 through an elastic body 14, and the elastic body 14 is used to push the slider 13 to one end of its stroke. The main shaft 2 is provided with a paddle 15 used in conjunction with the slider 13; Due to the restriction of the end of the arc-shaped slide groove 12 on the slider 13, the elastic thrust provided by the elastic body 14 to the slider 13 can fix the position of the slider 13, and at this time the position of the adjusting arm 7 is fixed; when the main shaft 2 rotates, it will drive the dial plate 15 to move synchronously. At this time, the main shaft 2 and the adjusting arm 7 move relative to each other. When the clamping unit 11 completes the grabbing work, the dial plate 15 abuts against the adjusting arm 7, the main shaft 2 rotates and uses the dial plate 15 to push the adjusting arm 7 to move, the slider 13 slides in the arc-shaped slide groove 12, and the adjusting arm 7 moves synchronously with the main shaft 2, thereby rotating and lifting the trash can above the bucket, and the driven arm 8 and the active arm are relatively stationary, thereby utilizing the control of the movement state of the adjusting arm 7 to realize the translation and flipping movement of the driven arm 8, and this chronotropic movement does not require additional power, and its operation is simple and convenient to control.

[0020] Furthermore, a turntable 16 is provided between the driven arm 8 and the clamping unit 11 , the turntable 16 rotates on the driven arm 8 , and the clamping unit 11 is fixed on the turntable 16 ; The clamping unit 11 includes a helical gear 24 provided on the end surface of the turntable 16 and two helical tooth columns 25 located on both sides of the helical gear 24. The helical gear 24 is in transmission connection with the helical tooth columns 25. Each helical tooth column 25 is provided with a side thrust portion for clamping the trash can. The turntable 16 can support the helical gear 24 and the helical gear column 25 thereon. The rotation axis of the helical gear column 25 is perpendicular to the rotation axis of the helical gear 24. When the helical gear 24 rotates, the helical gear 24 can drive the helical gear column 25 to rotate. The side pushers on the two helical gear columns 25 approach each other and close or open and separate. When the clamping unit 11 moves to the side of the trash can, the side pushers on the two helical gear columns 25 approach each other and clamp the trash can. The transmission method of the helical gear 24 and the helical gear column 25 is used. , which can realize the reversal of the power direction; since the pushing parts on both sides only perform the movement of opening and closing, the pushing parts on both sides can be opened and separated when idle, so that when clamping the trash can, they only need to be brought close to each other, and the opened state of the pushing parts on both sides will take up a large space, which is not conducive to the recovery of the clamping unit 11. Therefore, the push parts on both sides can be distributed up and down by rotating the turntable 16 on the driven arm 8. When the pushing parts on both sides perform the clamping work, the pushing parts on both sides are relatively distributed on the horizontal plane.

[0021] Furthermore, the side thrust portion includes a movable arm 26, a first clamping plate 27, and two second clamping plates 28. The movable arm 26 is fixedly connected to the helical tooth column 25. The first clamping plate 27 is located between the two second clamping plates 28. The first clamping plate 27 is rotatably connected to the second clamping plate 28. The second clamping plate 28 is rotatably connected to the movable arm 26. An elastic body 3 29 is provided between the second clamping plate 28 and the movable arm 26. The connection position of the first clamping plate 27 and the second clamping plate 28 is located between the two connection positions of the second clamping plates 28 and the movable arm 26; When the side pushing part approaches the side of the trash can, the splint 1 27 will first contact the trash can. At this time, the splint 1 27 stops moving, and the movable arm 26 will continue to provide side thrust for the two splints 28. The two splints 28 rotate on the splint 1 27, and the two splints 28 are close to each other, thereby utilizing the two splints 1 27 to realize the left and right clamping of the trash can, and utilizing the two splints 28 on each splint 1 27 to realize the front and back clamping of the trash can. At this time, the clamping unit 11 completes the surrounding clamping method of the trash can.

[0022] Furthermore, a plurality of adsorption structures 30 are provided on the clamping plate 1 27; when the clamping unit 11 completes the clamping and fixing work of the trash can, the adsorption effect of the adsorption structure 30 on the trash can is utilized to prevent the clamping plate 1 27 and the clamping plate 2 28 from slipping on the side wall of the trash can, thereby improving the clamping effect.

[0023] Furthermore, the adsorption structure 30 includes a fixed tube 31 inserted and fixed on the clamping plate 27, one end of the fixed tube 31 is open and the other end is sealed; A piston 32 is disposed within the fixed cylinder 31. An elastic member 33 is disposed on one side of the piston 32. The elastic member 33 is located on the opening side of the fixed cylinder 31 and is connected to the fixed cylinder 31. A movable tube 34 is disposed on the other side of the piston 32. An air hole 35 is formed on the outer wall of the movable tube 34. The end of the movable tube 34 slides out of the fixed cylinder 31 and is provided with a suction cup 36. When the splint 27 approaches the side of the trash can, the suction cup 36 will first contact the side wall of the trash can. At this time, the suction cup 36, the movable tube 34 and the piston 32 cannot move, and the fixed cylinder 31 moves relative to the piston 32. The space in the fixed cylinder 31 on the side where the piston 32 faces the suction cup 36 increases and a negative pressure environment is formed. The negative pressure is transmitted to the space between the suction cup 36 and the trash can through the air hole 35 and the movable tube 34, thereby achieving the adsorption of the trash can. This adsorption effect can be achieved by the structure itself without the need for an external air pump or other structure; when the piston 32 moves in the fixed cylinder 31, the elastic body 4 33 undergoes elastic deformation.

[0024] Furthermore, along the axis direction of the turntable 16, a second slider 17 and a third slider 18 are provided on the driven arm 8, and the third slider 18 slides on the driven arm 8. The second slider 17 and the third slider 18 are respectively provided with a threaded sleeve 19 and a threaded rod 20, and the threaded sleeve 19 is rotatably connected to the second slider 17, and the threaded sleeve 19 is threadedly connected to the threaded rod 20. The threaded sleeve 19 is provided with a transmission wheel 22 that is transmission-connected to the turntable 16. The slider 3 18 and the auxiliary arm 2 10 are rotatably connected via the auxiliary arm 3 21; When the adjusting arm 7 is stationary and the main shaft 2 rotates, the auxiliary arm 2 10 will rotate relative to the driven arm 8. The auxiliary arm 2 10 pulls the slider 3 18 to move on the driven arm 8 through the auxiliary arm 3 21. The slider 3 18 pulls the threaded rod 20 and the threaded sleeve 19 to move relative to each other. Since the threaded rod 20 is threadedly connected to the threaded sleeve 19, the threaded rod 20 will drive the threaded sleeve 19 to rotate. The threaded sleeve 19 uses the transmission wheel 22 to drive the turntable 16 to rotate. Therefore, when the active arm and the driven arm 8 move relative to each other, the turntable 16 moves synchronously; the slider 2 17 can support the threaded sleeve 19.

[0025] Furthermore, the second slider 17 slides within a prescribed stroke on the driven arm 8, and the second slider 17 is connected to the third slider 18 via the second elastic body 23; By utilizing elastic body 23, in the natural state, slider three 18 and slider two 17 are close to each other. When the main shaft 2 rotates and the adjusting arm 7 is stationary, the force of the auxiliary arm three 21 on the slider three 18 will utilize the elastic body 23 to pull the slider two 17 to move synchronously. At this time, the clamping unit 11 only follows the driven arm 8 to perform translational movement, and the turntable 16 is stationary on the driven arm 8. When the slider two 17 moves to the specified position, the slider two 17 stops moving, and the clamping unit 11 extends to the side of the garbage truck. At this time, the slider three 18 and the slider two 17 move relative to each other, the elastic body two 23 undergoes elastic deformation, and the threaded sleeve 19 will drive the turntable 16 to rotate through the transmission wheel 22. The orientation of the push parts on both sides of the turntable 16 changes from vertical distribution to horizontal distribution.

[0026] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
