Description

Technical Field

[0001] This utility model relates to the field of compressed garbage truck technology, specifically a compressed garbage truck with a garbage bin lifting structure. Background Technology

[0002] In recent years, with the development of waste disposal technology, garbage trucks have emerged. Highly mechanized garbage trucks can collect and clean up the huge amount of garbage generated in modern cities every day in a timely manner, alleviating urban waste problems. Therefore, they play a very important role in the field of modern waste disposal.

[0003] A relevant reference is Chinese utility model patent CN218663541U, which discloses a compressed garbage truck, including a truck body and a loader located at the rear of the truck body; a locking mechanism for locking the loader is provided between the loader and the truck body; a sealing plate mechanism is slidably mounted on the loader; an arc-shaped loading chamber is provided inside the loader; and a loading device that can operate in a first set area and a second set area is slidably mounted inside the loader; when the loading device slides and operates in the first set area, the loading device moves along the arc surface of the arc-shaped loading chamber; when the loading device slides and operates in the second set area, the loading device moves upward in a bent shape in coordination with the feed inlet of the truck body. As can be seen from the above description, by having the loading device operate in the first and second set areas, the garbage inside the loader enters the truck body without residue for compression, while the sealing plate mechanism can seal the garbage during transportation. The structure is simple and easy to operate, reducing the pollution of the environment by garbage odor.

[0004] The aforementioned compressed garbage truck uses an arc-shaped loading bin to hold garbage, and the scraper of the loading device moves the garbage inside the loading bin into the truck body. When the scraper moves the garbage, it can get stuck between the scraper and the bottom plate of the loading bin, requiring multiple transfer operations to completely move the garbage from the loading bin into the truck body, which affects the transfer efficiency. Furthermore, most of the internal compression components of existing compressed garbage trucks are flat structures, which cannot quickly deform structures with a certain degree of hardness, such as wood and metal, during the garbage compression process, thus affecting the compression efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a compressed garbage truck with a garbage bin lifting structure, which solves the problems of garbage not being able to fully enter the truck compartment during transportation and low compression efficiency.

A fixed plate is fixedly installed inside the receiving hopper. A movable plate is fitted below the fixed plate. A transmission piston is installed between the movable plate and the fixed plate. A connecting rod is fixedly installed above the movable plate. A scraper is movably installed below the movable plate. An auxiliary piston is movably installed above the scraper.

[0008] Preferably, the floor of the inner cavity of the carriage is provided with a sliding groove that fits into the protruding structure at the bottom of the push plate, one side of the push plate is provided with a toothed protrusion, one end of the multi-stage piston is rotatably connected to the push plate, and the other end of the multi-stage piston is rotatably connected to the tractor through a connecting base.

[0009] Preferably, the bottom of the receiving hopper has an arc-shaped structure, and a triangular cavity is provided at the bottom of the receiving hopper. A water channel is provided between the cavity structure at the bottom of the receiving hopper and the inner wall of the receiving hopper. One end of the lifting piston is rotatably connected to the carriage, and the other end of the lifting piston is rotatably connected to the receiving hopper.

[0010] Preferably, the movable plate and the fixed plate are slidably connected, and both the movable plate and the fixed plate are provided with a protrusion structure connected to the transmission piston on their upper surfaces. The fixed plate is provided with a groove that fits into the connecting rod on its upper surface. The top end of the connecting rod is rotatably connected to one end of the auxiliary piston. The scraper is rotatably connected to the bottom end of the movable plate, and a rod-shaped protrusion that forms a rotatable connection with the auxiliary piston is provided diagonally above the scraper.

[0011] Preferably, the lifting mechanism includes a drive shaft movably mounted on the outside of the receiving bucket, a connecting rod movably mounted above the drive shaft, a drive frame fixedly mounted below the drive shaft, and drive pistons movably mounted at both ends of the drive shaft.

[0012] Preferably, a baffle structure is provided above the drive shaft to limit the position of the trash can, and "L"-shaped drive rods are provided at both ends of the drive shaft. The front ends of the drive rods at both ends of the drive shaft are rotatably connected to the receiving hopper. The center of the drive shaft is provided with equally spaced obliquely upward protrusions. The top of the drive shaft is rotatably connected to the receiving hopper through connecting rods on both sides, and one end of the connecting rod is provided with a protrusion to limit the rotation angle. The front end of the drive piston is rotatably connected to the receiving hopper, and the rear end is rotatably connected to the lower ends of the drive rods at both ends of the drive shaft. Beneficial effects

[0013] This utility model provides a compressed garbage truck with a garbage bin lifting structure. Compared with the prior art, it has the following advantages:

[0014] (1) The compressed garbage truck with garbage bin lifting structure, through the setting of the auxiliary piston, the fixed plate can restrict the movement direction of the movable plate. The movable plate can move under the drive of the transmission piston, so that the rotation axis of the scraper below is in the same straight line as the center of the arc structure at the bottom of the receiving bucket. Thus, before transferring the garbage, the angle of the scraper is restricted by the auxiliary piston, so that when the rotation axis is in the same straight line as the center of the arc at the bottom of the receiving bucket, the bottom end of the scraper contacts the rear end of the receiving bucket, and the receiving bucket is closed. Then the auxiliary piston drives the scraper to rotate so that the outer edge of the scraper can fit into the arc at the bottom of the receiving bucket during the rotation process. The slope of the upward slope structure at the rear end of the receiving bucket is consistent with the tilt angle of the movable plate. Thus, after the scraper rotates, it can move upward along the slope structure of the receiving bucket and carry the garbage into the truck body. This method can prevent the garbage from getting stuck between the bottom end of the scraper and the bottom surface of the inner cavity of the receiving bucket during the transfer of garbage.

[0015] (2) The compressed garbage truck with garbage bin lifting structure has a toothed protrusion on one side of the push plate and a toothed protrusion on the rear side of the movable plate. The spacing between the toothed protrusions of the movable plate is greater than the spacing between the toothed structures of the push plate. This method can make the pressure on the garbage during the compression process non-uniform, so that the local pressure is concentrated at the tip of the toothed structure, so as to quickly break up large pieces of garbage with a certain hardness and reduce the probability of jamming.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a compressed garbage truck with a garbage bin lifting structure, including a tractor 1, a compartment 11 fixedly installed on the top of the tractor 1, a push plate 12 fitted inside the compartment 11, a multi-stage piston 13 movably installed on the back of the push plate 12, a connecting base 14 movably installed at the front end of the multi-stage piston 13, a sliding groove provided on the inner cavity floor of the compartment 11 that fits into the bottom protrusion structure of the push plate 12, a toothed protrusion provided on one side of the push plate 12, one end of the multi-stage piston 13 being rotatably connected to the push plate 12, and the other end of the multi-stage piston 13 being rotatably connected to the tractor 1 through the connecting base 14.

[0023] Specifically, the tractor 1 can move the carriage 11, the carriage 11 can limit the pulling position, the push plate 12 can move inside the carriage 11 under the drive of the multi-stage piston 13 and squeeze the garbage towards the rear of the carriage 11, the connecting base 14 can limit the position of the front end of the multi-stage piston 13, the multi-stage piston 13 passes through the front end of the carriage 11 and is connected to the tractor 1 through the connecting base 14.

[0024] A conveying mechanism 2 for transferring garbage is installed on the rear side of the carriage 11. The conveying mechanism 2 includes a receiving hopper 21 movably installed at the rear end of the carriage 11. A lifting piston 22 is fixedly installed on the outer side of the receiving hopper 21. A fixed plate 23 is fixedly installed inside the receiving hopper 21. A movable plate 24 is fitted below the fixed plate 23. A transmission piston 25 is installed between the movable plate 24 and the fixed plate 23. A connecting rod 26 is fixedly installed above the movable plate 24. A scraper 27 is movably installed below the movable plate 24. An auxiliary piston 28 is movably installed above the scraper 27. The bottom of the receiving hopper 21 has an arc-shaped structure and a triangular cavity is provided at the bottom of the receiving hopper 21. A water channel is provided between the cavity structure of the part and the inner wall of the receiving bucket 21. One end of the lifting piston 22 is rotatably connected to the carriage 11, and the other end of the lifting piston 22 is rotatably connected to the receiving bucket 21. The movable plate 24 and the fixed plate 23 are slidably connected. The upper part of the movable plate 24 and the fixed plate 23 are provided with a protrusion structure that connects to the transmission piston 25. The upper part of the fixed plate 23 is provided with a groove that fits into the connecting rod 26. The top end of the connecting rod 26 is rotatably connected to one end of the auxiliary piston 28. The scraper 27 is rotatably connected to the bottom end of the movable plate 24. The upper side of the scraper 27 is provided with a rod-shaped protrusion that forms a rotatable connection with the auxiliary piston 28.

[0025] Specifically, the receiving hopper 21 can receive the garbage poured out of the garbage bin. The lifting piston 22 can rotate the receiving hopper 21 around the axis of the top cylindrical protrusion structure, so that the garbage inside the truck compartment 11 can be discharged from the rear of the truck compartment 11 under the action of the push plate 12. The fixed plate 23 can restrict the movement direction of the movable plate 24. The movable plate 24 can move under the action of the transmission piston 25, so that the rotation axis of the lower scraper 27 is in the same straight line as the center of the arc-shaped structure at the bottom of the receiving hopper 21, so that the outer edge of the scraper 27 can be aligned with the bottom of the receiving hopper 21 during rotation. The arc-shaped fitting and the upward slope of the rear end of the receiving hopper 21 are consistent with the inclination angle of the movable plate 24. As a result, after the scraper 27 rotates, it can move obliquely upward along the slope of the receiving hopper 21. The auxiliary piston 28 can drive the scraper 27 to rotate. During the downward movement of the movable plate 24, the scraper 27 points to the rear side and is driven by the movable plate 24 to press down the garbage. During the garbage compression process, the liquid that seeps out can enter the bottom triangular cavity through the water channel on the inclined surface of the inner cavity of the receiving hopper 21. A solenoid valve is installed at the bottom of the cavity for discharging sewage.

[0026] A lifting mechanism 3 for dumping garbage bins is installed on the rear side of the carriage 11. The lifting mechanism 3 includes a drive shaft 31 movably installed on the outside of the receiving hopper 21. A connecting rod 32 is movably installed above the drive shaft 31. A transmission frame 33 is fixedly installed below the drive shaft 31. Drive pistons 34 are movably installed at both ends of the drive shaft 31. A baffle structure restricting the position of the garbage bin is provided above the drive shaft 31. "L"-shaped transmission rods are provided at both ends of the drive shaft 31. The front ends of the transmission rods at both ends of the drive shaft 31 are rotatably connected to the receiving hopper 21. The center of the drive shaft 31 is provided with equidistantly distributed obliquely upward protrusions. The top of the drive shaft 31 is rotatably connected to the receiving hopper 21 through the connecting rods 32 on both sides. One end of the connecting rod 32 is provided with a protrusion restricting the rotation angle. The front end of the drive piston 34 is rotatably connected to the receiving hopper 21, and the rear end is rotatably connected to the lower ends of the transmission rods at both ends of the drive shaft 31.

[0027] Specifically, the equidistant protrusions on the left side and the plate-like protrusions on the right side of the drive shaft 31 can engage with the protruding structure on the outer side of the top of the trash can, so that the position between the trash can and the drive shaft 31 can be restricted when the drive shaft 31 rotates. By driving the piston 34 to drive the drive shaft 31 to rotate, the trash can is flipped upward under the drive of the drive shaft 31 and the drive frame 33. After the limiting protrusion at the right end of the connecting rod 32 contacts the receiving hopper 21, the rotation axis is transferred to the top of the connecting rod 32, so that the trash can is inverted to facilitate the dumping of trash. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0028] During operation, the fixed plate 23 restricts the movement direction of the movable plate 24. The movable plate 24 moves under the drive of the transmission piston 25, ensuring that the rotation axis of the lower scraper 27 is aligned with the center of the arc-shaped structure at the bottom of the receiving hopper 21. Before transferring waste, the auxiliary piston 28 restricts the angle of the scraper 27, ensuring that when its rotation axis is aligned with the center of the arc-shaped structure at the bottom of the receiving hopper 21, the bottom of the scraper 27 contacts the rear end of the receiving hopper 21, sealing the hopper 21. Then, the auxiliary piston 28 drives the scraper 27 to rotate, allowing its outer edge to engage with the arc-shaped structure at the bottom of the receiving hopper 21 during rotation. The upward slope of the rear end of the receiving hopper 21 is consistent with the movement of the movable plate 24. The inclination angles of the plates 24 are consistent, so that after the scraper 27 rotates, it can move obliquely upward along the slope structure of the receiving hopper 21, and carry the garbage into the compartment 11. This method can prevent the garbage from getting stuck between the bottom end of the scraper 27 and the bottom surface of the inner cavity of the receiving hopper 21 during the garbage transfer process. One side of the pusher 12 is provided with toothed protrusions, and the rear side of the movable plate 24 is also provided with toothed protrusions. The spacing between the toothed protrusions of the movable plate 24 is greater than the spacing between the toothed structures of the pusher 12. This method can make the pressure on the garbage during the compression process non-uniform, so that the local pressure is concentrated at the tip of the toothed structure, so as to quickly break up large pieces of garbage with a certain degree of hardness and reduce the probability of jamming.
