[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 9 As shown, a squeeze compartment for a garbage truck of the present invention comprises: A base structure 1, mounted on a garbage truck; The carriage 2 is used to store garbage and is installed on the base structure 1. The bottom shape of the rear opening of the carriage 2 is set as an arc-shaped collection area 3; The squeezing plate 4 is used to squeeze the garbage in the compartment 2. The squeezing plate 4 is composed of an upper plate 5 located on the upper side and a lower plate 6 located on the lower side. A plurality of first sliders 7 are vertically slidably arranged on the side wall of the upper plate 5. A rotating shaft 8 is rotatably inserted through the plurality of first sliders 7. The lower plate 6 is fixed on the rotating shaft 8. A pushing structure, used for pushing the extrusion plate 4 to move obliquely in the carriage 2; The lower plate 6 cooperates with the shape of the arc-shaped collecting area 3 through the rotation trajectory of the rotating shaft 8 on the upper side.

[0019] In detail, the carriage 2 is installed on the garbage truck through the base structure 1, and workers can pour garbage directly into the arc-shaped collection area 3. The shape of the arc-shaped collection area 3 can help collect the garbage. When the lower plate 6 is rotated to a horizontal state on the first slider 7 through the rotating shaft 8, the bottom of the extrusion plate 4 is open. At this time, the garbage in the arc-shaped collection area 3 can enter the carriage 2 through the opening, and the lower plate 6 can be rotated and use the plane thereon to assist in pushing the garbage in the arc-shaped collection area 3 into the carriage 2, so as to realize automatic garbage collection.

[0020] When in use, the extrusion plate 4 is located near the rear opening of the carriage 2, and the extrusion plate 4 is vertical. At this time, the axis of the rotating shaft 8 coincides with the axis of the arc-shaped collecting area 3, so that the first slider 7 slides upward on the upper plate 5 and lifts the lower plate 6. The lower plate 6 is in a vertical state and moves upward. When the first slider 7 moves to the end of its stroke, the first slider 7 stops moving and rotates the rotating shaft 8. The rotating shaft 8 drives the lower plate 6 to rotate. The lower plate 6 rotates from a vertical state to a horizontal state. After that, the first slider 7 moves down to the initial position, and the rotating shaft 8 is rotated in the opposite direction. The rotating shaft 8 drives the lower plate 6 to rotate. The lower plate 6 moves The garbage is pushed into the arc-shaped collection area 3 and into the carriage 2, thereby realizing the garbage collection work. When there is a lot of garbage collected in the carriage 2, the squeezing plate 4 can be pushed to move horizontally in the carriage 2 through the pushing structure, and the squeezing plate 4 is in an inclined state, and the squeezing plate 4 is inclined upward toward the surface of the inner side of the carriage 2. In this way, when the squeezing plate 4 contacts the garbage, the squeezing plate 4 will shovel the garbage, so that part of the garbage on the lower side of the carriage 2 gathers to the upper side of the carriage 2, thereby making the garbage evenly distributed in the vertical direction, and the squeezing plate 4 extrude and compact the garbage.

[0021] It should be pointed out here that since the squeezing plate 4 exerts a tilting force on the garbage, relatively more garbage is gathered on the upper side of the interior of the carriage 2, which can leave more space on the lower side of the interior of the carriage 2 to facilitate the subsequent entry of garbage. Of course, the squeezing plate 4 can also be tilted when shoveling the garbage through the pushing structure, and the squeezing plate 4 can be vertical when squeezing the garbage to achieve a planar squeezing effect on the garbage.

[0022] By utilizing the squeezing plate 4 to achieve the working effect of tilting and squeezing the garbage, the garbage in the carriage 2 can be conveniently gathered to the upper side of the interior of the carriage 2, thereby facilitating the uniform distribution of the garbage in the vertical direction of the carriage 2, and avoiding the garbage only gathering on the lower side of the interior of the carriage 2, while the upper space inside the carriage 2 cannot be effectively utilized; since the garbage can be filled in the vertical direction inside the carriage 2, the inner wall of the carriage 2 can be conveniently used to limit the garbage, and combined with the squeezing of the squeezing plate 4, the squeezing and cohesion force of the garbage can be made more direct and effective, thereby improving the garbage squeezing effect, and avoiding the phenomenon that the upper side of the garbage inside the carriage 2 is not effectively limited in the traditional way, resulting in the garbage being easily loosened; by adopting the combination of the lower plate 6 and the upper plate 5, and utilizing the multi-form movement of the lower plate 6, the automatic introduction and gathering of the garbage can be realized, and the garbage can be conveniently passed through the squeezing plate 4 into the carriage 2, thereby reducing manual intervention and improving work efficiency.

[0023] Furthermore, the upper plate 5 is composed of a first partition plate 9 and a second partition plate 10 which are distributed up and down. The first partition plate 9 and the second partition plate 10 are connected by a plurality of first cylinders 11. A sealing edge 12 is provided on the working surface of the second partition plate 10. The sealing edge 12 is attached to the working surface of the first partition plate 9, and the first partition plate 9 is vertically slidably connected to the sealing edge 12.

[0024] In detail, when the extrusion plate 4 is in the rear opening position of the carriage 2, the extrusion plate 4 is vertical. At this time, the rotation of the lower plate 6 can better push and collect the garbage. When the extrusion plate 4 is shoveling the garbage, the extrusion plate 4 needs to be in an inclined state. At this time, in order to ensure that the upper and lower ends of the extrusion plate 4 can still contact the upper and lower sides of the inner wall of the carriage 2, the overall length of the extrusion plate 4 needs to be increased, so that the extrusion plate 4 can completely seal the interior of the carriage 2. The specific operation can be achieved by the first cylinder 11 pushing the second sub-plate 10 to slide on the first sub-plate 9. The edge sealing 12 will seal the gap between the first sub-plate 9 and the second sub-plate 10, so that the extrusion plate 4 can still maintain a complete plane.

[0025] Furthermore, a second cylinder 13 is rotatably provided on the second split plate 10, a first cross bar 14 is provided at the movable end of the second cylinder 13, first oblique arms 15 are provided at both ends of the first cross bar 14, the first cross bar 14 is rotatably connected to the first oblique arms 15, and the first oblique arms 15 are fixed on the outer wall of the rotating shaft 8; When the lower plate 6 is vertical, the first oblique arm 15 tilts downward, and a locking structure is provided between the rotating shaft 8 and the first sliding block 7 .

[0026] In detail, the locking structure is used to lock the first slider 7 and the rotating shaft 8. When the lower plate 6 needs to be lifted, the second cylinder 13 contracts, and the second cylinder 13 pulls the rotating shaft 8, the first slider 7 and the lower plate 6 upward through the first cross bar 14 and the first oblique arm 15, and the lower plate 6 is vertical. When the first slider 7 moves to the end of its stroke, the first slider 7 stops moving. At this time, the locking structure releases the first slider 7 and the rotating shaft 8, and the second cylinder 13 continues to contract and pulls the rotating shaft 8 to rotate on the first slider 7 through the first cross bar 14 and the first oblique arm 15, so that The lower plate 6 rotates from a vertical state to a horizontal state, and the locking structure locks the first slider 7 and the rotating shaft 8 again. Then the second cylinder 13 extends, and the lower plate 6 in the horizontal state moves downward. When the first slider 7 moves downward to the initial position, it stops moving, and the locking structure is unlocked. The second cylinder 13 continues to extend and pushes the lower plate 6 and the rotating shaft 8 to rotate on the first slider 7 through the first cross bar 14 and the first inclined arm 15. At this time, the lower plate 6 pushes the garbage in the arc-shaped collection area 3 into the carriage 2, thereby realizing the control and transformation of various functional movement forms of the lower plate 6.

[0027] Further, the outer wall of the first sliding block 7 is arranged to be arc-shaped, and teeth are arranged on the arc-shaped outer wall of the first sliding block 7; The locking structure includes an arc-shaped tooth 18 used in conjunction with the teeth on the first slider 7 and a fixed sleeve 16 fixed on the side wall of the lower plate 6. A sliding rod 17 is slidably inserted into the fixed sleeve 16. One end of the sliding rod 17 is fixedly connected to the arc-shaped tooth 18, and the other end of the sliding rod 17 is connected to the lower plate 6 through a first leaf spring 19.

[0028] In detail, the first leaf spring 19 provides an elastic thrust to the slide rod 17 and the arc-shaped tooth slope 18, so that the arc-shaped tooth slope 18 maintains a locking state with the teeth on the first slider 7, thereby locking the first slider 7 and the rotating shaft 8. When the first slider 7 moves to the end position of its stroke, the first slider 7 cannot continue to move. At this time, the second cylinder 13 continues to contract or extend, and the second cylinder 13 will overcome the elastic force of the first leaf spring 19 and push the arc-shaped tooth slope 18 and the teeth on the first slider 7 to produce a staggered tooth movement, thereby causing the lower plate 6 to rotate on the first slider 7.

[0029] Further, the pushing structure includes two moving seats 20 slidably installed on the top of the inner wall of the carriage 2 along the length direction of the carriage 2, the moving seat 20 and the first split plate 9 on the extrusion plate 4 are mutually attached and connected by a second leaf spring 24, an arc groove 21 is opened on the side wall of the moving seat 20, a second slider 22 is slidably arranged in the arc groove 21, the second slider 22 is fixedly connected to the first split plate 9 on the extrusion plate 4, and the two second sliders 22 on the two moving seats 20 are connected by a second cross bar 23, and a plurality of third cylinders 25 are arranged on the carriage 2, and a second oblique arm 26 is rotatably arranged at the movable end of the third cylinder 25, and the second oblique arm 26 is rotatably connected to the second cross bar 23; The center of the arc groove 21 coincides with the center point of the top of the first sub-plate 9 .

[0030] In detail, since the center of the arc groove 21 coincides with the center point of the top of the first dividing plate 9, when the second sliding block 22 slides on the arc groove 21, the top of the first dividing plate 9 can always contact the top of the inner wall of the carriage 2, and the top position of the first dividing plate 9 is relatively stationary with respect to the moving seat 20. The second leaf spring 24 can provide an elastic thrust for the first dividing plate 9. In the initial position, the squeezing plate 4 is vertical, the second leaf spring 24 is in an elastically deformed state, and the moving seat 20 is at the end of its stroke. When it is necessary to squeeze the garbage, the third cylinder 25 extends and passes through the second inclined arm 26 and the second cross arm 24. The rod 23 pushes the second slider 22 to slide on the arc groove 21. Due to the action of the second leaf spring 24, the second slider 22 will first push the first dividing plate 9 to move, that is, the first dividing plate 9 rotates from a vertical state to an inclined state. At this time, the extrusion plate 4 is tilted as a whole. When the second slider 22 moves to the end of its stroke in the arc groove 21, the second slider 22 stops moving, and the third cylinder 25 uses the second slider 22 to push the moving seat 20 to move horizontally. At this time, the moving seat 20 and the extrusion plate 4 move horizontally synchronously, and the extrusion plate 4 in the inclined state shovels the garbage.

[0031] Since the squeezing plate 4 and the moving seat 20 are connected by the second leaf spring 24, when the squeezing plate 4 squeezes the garbage, the lower part of the squeezing plate 4 is subjected to a larger reaction force from the garbage, and the reaction force overcomes the elastic force of the second leaf spring 24 and restores the squeezing plate 4 from an inclined state to a vertical state, and the second slider 22 moves in the arc groove 21 to the other end of the stroke of the second slider 22, and the pushing structure generates a thrust on the squeezing plate 4 in the vertical state and uses the squeezing plate 4 in this state to complete the squeezing work on the garbage.

[0032] Further, the carriage 2 rotates on the base structure 1; The side wall of the carriage 2 facing the front of the garbage truck is set as the head of the carriage 2. The head of the carriage 2 is open, and the garbage in the carriage 2 is discharged through the head opening of the carriage 2. The upper cover of the head opening of the carriage 2 is equipped with two sealing plates 27, which are distributed up and down. The two sealing plates 27 are rotatably connected to each other. The top of the upper sealing plate 27 is rotatably mounted on the carriage 2, and the bottom of the lower sealing plate 27 is provided with a connecting shaft 30 on the front and rear side walls. Vertical beams 28 are vertically arranged on the front and rear side walls of the carriage 2, and a third slider 29 is slidably arranged in the vertical beam 28. The connecting shaft 30 is rotatably mounted on the third slider 29; Among them, a side plate 31 is vertically arranged on the side wall of the upper sealing plate 27, and the top of the side plate 31 is arranged as an outer inclined portion 32, which is inclined in a direction away from the carriage 2, and the outer inclined portion 32 is connected to the carriage 2 through a fourth cylinder 33.

[0033] In detail, the fixed end of the fourth cylinder 33 is rotatably mounted on the carriage 2, and the movable end of the fourth cylinder 33 is rotatably mounted on the outer oblique portion 32. When the garbage truck carries the carriage 2 and the garbage inside to the specified position, the carriage 2 is rotated 90 degrees on the base structure 1. At this time, the head of the carriage 2 faces the side of the garbage truck, and the fourth cylinder 33 contracts. The fourth cylinder 33 drives the upper sealing plate 27 to rotate through the outer oblique portion 32 and the side plate 31, and the upper sealing plate 27 pulls the lower sealing plate 27 to rotate synchronously. The lower sealing plate 27 drives the third slider 29 to slide on the vertical beam 28 through the connecting shaft 30. The vertical beam 28, the third slider 29 and the connecting shaft 30 guide and limit the bottom of the lower sealing plate 27, so that the two sealing plates 27 are gradually flipped from a vertical coplanar state to a horizontal coplanar state, and the two sealing plates 27 are fitted to each other. Both sealing plates 27 are located on the upper side of the head opening of the carriage 2, so that the garbage can be discharged smoothly through the head opening of the carriage 2 by the pushing action of the squeezing plate 4.

[0034] Furthermore, the bottom of the side plate 31 is configured as a lower edge 34 , and the lower edge 34 is used to block the side wall of the sealing plate 27 at the lower side.

[0035] In detail, the lower edge 34 extends downward to the outer wall position of the lower side sealing plate 27, so that when the two sealing plates 27 are in a blocked state, the lower edge 34 can generate a lateral thrust on the lower side sealing plate 27, thereby improving the overall blocking strength of the two sealing plates 27, and this method does not affect the normal opening of the two sealing plates 27.

[0036] Furthermore, the base structure 1 includes a turntable 35 fixed to the bottom of the carriage 2, a fixed cylinder 36 is sleeved on the outer side of the turntable 35, the turntable 35 rotates on the fixed cylinder 36, a bottom plate 37 is fixed to the bottom of the fixed cylinder 36, the bottom plate 37 is fixed to the garbage truck, a fifth cylinder 38 is rotatably arranged on the bottom plate 37, the movable end of the fifth cylinder 38 is eccentrically mounted on the bottom end surface of the turntable 35, and the fifth cylinder 38 is rotatably connected to the turntable 35.

[0037] In detail, the turntable 35 , the fixed cylinder 36 and the fifth cylinder 38 can support the carriage 2 . When the fifth cylinder 38 is extended or retracted, the fifth cylinder 38 can push the turntable 35 to rotate on the fixed cylinder 36 , thereby controlling the direction of the carriage 2 .

[0038] The above is only a preferred embodiment 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.
