Description

Technical Field

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

[0002] As the core equipment for urban solid waste transportation, the efficiency of garbage trucks in the garbage loading process directly affects the overall operational efficiency. In the current mainstream system, the dumping of garbage bins mainly relies on conveyor chain or hook-type lifting devices. This mode requires sanitation workers to manually drag or push the garbage bins to the side of the vehicle to a fixed lifting point for hooking or positioning before the lifting mechanism can be started. During this process, workers need to frequently travel between the garbage bin parking point and the vehicle to carry heavy loads, resulting in high labor intensity and a harsh working environment. At the same time, due to the mechanical characteristics of traditional lifting structures (such as chain tracks or hook constraints), garbage bins can usually only reach a certain tilt angle (such as 45°-70°) when lifted and dumped, making it difficult to achieve a near-vertical (such as above 85°) complete dumping state. Adhesive garbage (such as wet garbage and compressed garbage) remaining at the bottom or inner wall of the bin cannot be completely emptied, leading to garbage retention, odor generation, and even affecting the subsequent normal use of the bin. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a garbage truck lifting and dumping structure, the specific technical solution of which is as follows:

[0004] The present invention provides a garbage truck lifting and dumping structure, comprising a base, an active arm and a driven arm. A main shaft is rotatably mounted on the base, and a power wheel is fixed on the main shaft. The active arm includes two side arms arranged opposite to each other and a plurality of connecting columns connecting the two side arms. One end of each of the two side arms is mounted on the main shaft. An arc-shaped opening coaxial with the main shaft is opened on one of the side arms near the base, and an adjusting arm is inserted into the arc-shaped opening.

[0005] One end of the driven arm is rotatably connected to the other ends of the two side arms. The other end of the driven arm is provided with a clamping unit. Parallel auxiliary arms 1 are provided on both the driven arm and the adjusting arm. The two auxiliary arms 1 are rotatably connected to each other through auxiliary arms 2.

[0006] Furthermore, the base is provided with an arc-shaped groove coaxial with the main shaft, and a slider is slidably disposed in the arc-shaped groove. The slider moves within a specified stroke. The adjusting arm is fixedly connected to the slider. The slider and the base are connected by an elastic body. The elastic body is used to push the slider to one end of its stroke. The main shaft is provided with a lever plate that cooperates with the slider.

[0007] Furthermore, a turntable is provided between the driven arm and the clamping unit, the turntable rotates on the driven arm, and the clamping unit is fixed on the turntable;

[0008] The clamping unit includes a helical gear disposed on the end face of the turntable and two helical gear columns located on both sides of the helical gear. The helical gear is connected to the helical gear columns in a driving manner, and each of the helical gear columns is provided with a side push part for clamping the trash can.

[0009] Furthermore, the side push part includes a movable arm, a clamping plate one and two clamping plates two. The movable arm is fixedly connected to the helical tooth column. The clamping plate one is located between the two clamping plates two and is rotatably connected to the clamping plates two. The clamping plates two are rotatably connected to the movable arm, and an elastic body three is provided between the clamping plates two and the movable arm.

[0010] The connection point between clamp plate one and clamp plate two is located between the two connection points of clamp plate two and the movable arm.

[0011] Furthermore, the clamp is provided with several adsorption structures.

[0012] Furthermore, the adsorption structure includes a fixing cylinder that is inserted and fixed on a clamping plate, with one end of the fixing cylinder open and the other end sealed.

[0013] A piston is provided inside the fixed cylinder. An elastic body four is provided on one side of the piston. The elastic body four is located on the opening side of the fixed cylinder and is connected to the fixed cylinder. A movable tube is provided on the other side of the piston. An air hole is provided on the outer wall of the movable tube. The end of the movable tube slides out of the fixed cylinder and is provided with a suction cup.

[0014] Furthermore, along the axis of the turntable, the driven arm is provided with slider two and slider three, and slider three slides on the driven arm. Slider two and slider three are respectively provided with threaded sleeves and threaded rods, and the threaded sleeve is rotatably connected to slider two. The threaded sleeve is threadedly connected to the threaded rod, and the threaded sleeve is provided with a transmission wheel that is connected to the turntable transmission.

[0015] The slider three and the auxiliary arm two are rotatably connected by the auxiliary arm three.

[0016] Furthermore, the second slider slides within a predetermined stroke on the driven arm, and the second slider and the third slider are connected by an elastic body.

[0017] The beneficial effects of this invention are as follows:

[0018] By employing a rotating lifting mechanism to raise the garbage bins above the truck bed, the tilting angle of the bins can be freely controlled, facilitating garbage disposal and preventing the garbage from being restricted from falling due to a small tilting angle. The articulated boom structure, composed of an active and driven boom, can be easily folded and concealed between the truck bed and cab, thus reducing the width of the garbage truck. Furthermore, the grab-and-dump method eliminates the need for workers to move the garbage bins to a designated location, saving manpower and reducing prolonged contact between workers and the garbage bins.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on this invention.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0032] 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 mounted on the base 1, and a power wheel 3 is fixed on the main shaft 2. The active arm includes two opposing arms 4 and a plurality of connecting columns 5 connecting the two arms 4. One end of each of the two arms 4 is mounted on the main shaft 2. An arc-shaped opening 6 coaxial with the main shaft 2 is opened on the arm 4 closest to the base 1, and an adjusting arm 7 is inserted into the arc-shaped opening 6.

[0033] One end of the boom 8 is rotatably connected to the other end of the two arms 4. A clamping unit 11 is provided at the other end of the boom 8. Parallel auxiliary arms 9 are provided on both the boom 8 and the adjusting arm 7. The two auxiliary arms 9 are rotatably connected by auxiliary arms 2 10.

[0034] In this invention, to save space, the dumping structure is generally installed between the front and the bucket of the garbage truck. This way, the overall structure does not occupy 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 with bolts. The main shaft 2 provides support for the driving arm and the driven arm 8. Since the main shaft 2 needs to rotate, a power wheel 3 can be connected to the main shaft 2 to provide power. Specifically, a motor or other power structure can be set on the base 1 to drive the power wheel 3 to rotate, thereby driving the driving arm to rotate. The arrangement of the two side arms 4 can provide installation space for the auxiliary arms 1 9 and 2 10, allowing the auxiliary arms 1 9 and 2 10 to be hidden. Between the two side arms 4, this structural arrangement of the two side arms 4 can reduce the weight of the active arm, thereby reducing the weight of the overall structure; several connecting columns 5 connect and fix the two side arms 4, and the connection between the connecting columns 5 and the side arms 4 can be achieved by bolts, welding, snap-fitting, etc.; the arc-shaped opening 6 can provide a space for the adjusting arm 7 to pass through, and since the active arm and the main shaft 2 need to rotate, the adjusting arm 7 can move within a specified angle range along the circumference of the main shaft 2 within the arc-shaped opening 6. This provides a connection position for the main shaft 2 and the side arms 4, provides support space for the adjusting arm 7, and allows relative movement between the main shaft 2 and the adjusting arm 7.

[0035] It should be noted that the active arm and the driven arm 8 can form a curved arm structure to facilitate the support of the clamping unit 11 and carry the clamping unit 11 to move. By using the arrangement of the two auxiliary arms 1 9 and auxiliary arm 2 10, a parallelogram structure can be formed. When the main shaft 2 rotates, auxiliary arms 1 9 and 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 motion. When the adjusting arm 7 actively moves 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 motion. Thus, by controlling the movement mode and timing of the adjusting arm 7, the driven arm 8 can be controlled in multiple ways.

[0036] In use, the active arm and driven arm 8 bend and retract within the space between the garbage truck's bucket and cab. When the garbage truck reaches the designated position, the main shaft 2 and drive wheel 3 rotate, and the adjusting arm 7 comes to a standstill. 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 garbage bin position and clamp the garbage bin. Afterward, 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 garbage can in an arc motion, thereby lifting the garbage can above the front of the vehicle and flipping the garbage can so that the opening of the garbage can faces downward, so that the garbage can fall into the truck bed; during the garbage dumping process, the driven arm 8 can be moved relative to the driving arm by controlling the adjusting arm 7 to be stationary or moving, thereby causing the garbage can to vibrate and making it easier for the garbage inside the garbage can to fall out; since the adjusting arm 7 and the main shaft 2 have multiple modes of movement, a separate power source can be set up for the adjusting arm 7;

[0037] By employing a rotating lifting mechanism to raise the garbage bins above the truck bed, the tilting angle of the bins can be freely controlled, facilitating garbage disposal and preventing the garbage from being restricted from falling due to a small tilting angle. The articulated boom structure, composed of an active boom and a driven boom, can be easily folded and concealed between the truck bed and the cab, thus reducing the width of the garbage truck. Furthermore, the grab-and-dump method eliminates the need for workers to move the garbage bins to a designated location, saving manpower and preventing workers from prolonged contact with the garbage bins.

[0038] Furthermore, an arc-shaped groove 12 coaxial with the main shaft 2 is provided on the base 1. A slider 13 is slidably arranged in the arc-shaped groove 12 and moves within a specified stroke. The adjusting arm 7 is fixedly connected to the slider 13. The slider 13 is connected to the base 1 through an elastic body 14. The elastic body 14 is used to push the slider 13 to one end of its stroke. A lever 15 is provided on the main shaft 2 to cooperate with the slider 13.

[0039] Because the end of the arc-shaped chute 12 restricts 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 the position of the adjusting arm 7 is fixed at this time. 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. After the clamping unit 11 completes the gripping 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 chute 12, and the adjusting arm 7 moves synchronously with the main shaft 2, thereby rotating and lifting the garbage can to the top of the truck bed. The driven arm 8 and the driving arm are relatively stationary. By controlling the movement state of the adjusting arm 7, the movement mode of translation and flipping of the driven arm 8 can be realized. Moreover, this sequential movement mode does not require additional power, and its operation is simple and easy to control.

[0040] Furthermore, a turntable 16 is provided between the driven boom 8 and the clamping unit 11. The turntable 16 rotates on the driven boom 8, and the clamping unit 11 is fixed on the turntable 16.

[0041] The clamping unit 11 includes a helical gear 24 disposed on the end face of the turntable 16 and two helical gear columns 25 located on both sides of the helical gear 24. The helical gear 24 and the helical gear columns 25 are connected in a transmission manner. Each helical gear column 25 is provided with a side push part for clamping the garbage can.

[0042] The turntable 16 supports the helical gear 24 and helical gear 25. The rotation axis of the helical gear 25 is perpendicular to the rotation axis of the helical gear 24. When the helical gear 24 rotates, it drives the helical gear 25 to rotate. The side push parts on the two helical gears 25 move closer together and close or open and separate. When the clamping unit 11 moves to the side of the garbage can, the side push parts on the two helical gears 25 move closer together and clamp and fix the garbage can. The transmission method of the helical gear 24 and the helical gear 25 is utilized. It can realize the reversal of the power direction; since the two push parts only perform the opening and closing movement, when idle, the two push parts can open and separate. So when clamping the trash can, it is only necessary to bring them close together. However, the open state of the two push parts will occupy a large space, which is not conducive to the recovery of the clamping unit 11. Therefore, the two push parts can be distributed vertically by rotating the turntable 16 on the driven arm 8. When the two push parts are performing clamping work, the two push parts are distributed relative to each other on the horizontal plane.

[0043] Furthermore, the side-pushing part includes a movable arm 26, a clamping plate 27, and two clamping plates 28. The movable arm 26 is fixedly connected to the helical tooth column 25. The clamping plate 27 is located between the two clamping plates 28 and is rotatably connected to the clamping plates 28. The clamping plates 28 are rotatably connected to the movable arm 26, and an elastic body 29 is provided between the clamping plates 28 and the movable arm 26.

[0044] Among them, the connection position of clamping plate 1 27 and clamping plate 28 is located between the two connection positions of clamping plate 28 and movable arm 26;

[0045] When the side pusher approaches the side of the trash can, clamp plate 27 will first contact the trash can. At this time, clamp plate 27 stops moving, and the movable arm 26 will continue to provide a pushing force to the two clamp plates 28. The two clamp plates 28 rotate on clamp plate 27 and come together with each other. Thus, the two clamp plates 27 are used to clamp the trash can from left to right, and the two clamp plates 28 on each clamp plate 27 are used to clamp the trash can from front to back. At this time, the clamping unit 11 completes the surrounding clamping method of the trash can.

[0046] Furthermore, the clamping plate 27 is provided with several adsorption structures 30; when the clamping unit 11 completes the clamping and fixing of the trash can, the adsorption effect of the adsorption structure 30 on the trash can is used to avoid the clamping plate 27 and the clamping plate 28 from slipping on the side wall of the trash can, thereby improving the clamping effect.

[0047] Furthermore, the adsorption structure 30 includes a fixing cylinder 31 that is inserted and fixed on the clamping plate 27, with one end of the fixing cylinder 31 open and the other end sealed.

[0048] A piston 32 is provided inside the fixed cylinder 31. An elastic body 33 is provided on one side of the piston 32. The elastic body 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 provided on the other side of the piston 32. An air hole 35 is provided on the outer wall of the movable tube 34. The end of the movable tube 34 slides out of the fixed cylinder 31 and a suction cup 36 is provided at the end of the movable tube 34.

[0049] When the clamp 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. The fixed cylinder 31 moves relative to the piston 32. The space in the fixed cylinder 31 facing the suction cup 36 increases and a negative pressure environment is formed. The negative pressure is transmitted to the suction cup 36 and the trash can through the air hole 35 and the movable tube 34, thereby realizing the adsorption of the trash can. This adsorption effect can be achieved by the structure itself without the need for external air pumps or other structures. When the piston 32 moves in the fixed cylinder 31, the elastic body 33 undergoes elastic deformation.

[0050] Furthermore, along the axis 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. A threaded sleeve 19 and a threaded rod 20 are respectively provided on the second slider 17 and the third slider 18. 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. A transmission wheel 22 that is connected to the turntable 16 is provided on the threaded sleeve 19.

[0051] Slider 3 18 and auxiliary arm 2 10 are rotatably connected by auxiliary arm 3 21;

[0052] When the adjusting arm 7 is stationary and the main shaft 2 rotates, the secondary arm 10 will rotate relative to the driven arm 8. The secondary arm 10 pulls the slider 18 on the driven arm 8 through the secondary arm 21. The slider 18 pulls the threaded rod 20 and the threaded sleeve 19 to move relative to each other. Since the threaded rod 20 and the threaded sleeve 19 are threadedly connected, the threaded rod 20 will drive the threaded sleeve 19 to rotate. The threaded sleeve 19 drives the turntable 16 to rotate through the transmission wheel 22. Thus, when the driving arm and the driven arm 8 move relative to each other, the turntable 16 moves synchronously. The slider 17 can support the threaded sleeve 19.

[0053] Furthermore, slider 2 17 slides within a specified stroke on driven arm 8, and slider 2 17 and slider 3 18 are connected by elastic body 2 23;

[0054] Using the second elastic body 23, in the natural state, the third slider 18 and the second slider 17 approach each other. When the main shaft 2 rotates and the adjusting arm 7 is stationary, the force of the third auxiliary arm 21 on the third slider 18 will use the second elastic body 23 to pull the second slider 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 second slider 17 moves to the specified position, the second slider 17 stops moving, and the clamping unit 11 extends to the side of the garbage truck. At this time, the third slider 18 and the second slider 17 move relative to each other, the second elastic body 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.

[0055] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
