[0007] As a further optimization, in order to compress the waste stored inside the container, the compression mechanism includes: The hydraulic cylinder is vertically fixedly mounted on the end of the housing body away from the slope window. The telescopic end of the hydraulic cylinder is fixed with a pressure plate through the outer wall of the box body; A hydraulic system, whose input and output ends are fixedly connected to a hydraulic cylinder.

[0008] As a further optimization, in order to improve the wear resistance of the contact surface and extend its service life by using steel plates, stainless steel, which has good resistance to acid and alkali corrosion, is specifically used. The pressure plate includes: A flat plate, one side of which is fixedly connected to the telescopic end of the hydraulic system; A wedge-shaped groove is provided on the other side of the plate along its length. The steel plate has a wedge-shaped slider integrally formed on its outer wall corresponding to the wedge-shaped groove. The wedge-shaped slider is slidably inserted into the wedge-shaped groove; The steel plate is uniformly and integrally formed with an arched protrusion on the side away from the flat plate.

[0009] As a further optimization, in order to collect the leachate generated from waste compression and to periodically discharge the collected leachate, a leachate collection tank is installed at the lower end of the tank body, which includes: The mesh panel replaces the bottom surface of the box body; The upper end of the trough is fixedly connected to the lower end of the box body; The lower end of the outer wall of the tank is fixedly connected to a discharge pipe with a valve.

[0010] As a further optimization, in order to periodically backwash the inner cavity of the tank and avoid leachate residue, backwashing components are installed on both the left and right sides of the bottom surface of the tank, which include: A connecting pipe, which is fixedly connected to the bottom surface of the tank; The upper left and right sides of the connecting pipe are respectively fixed with a three-way pipe, and the other two ends extend to the left and right sides of the inner cavity of the tank. The lower end of the connecting pipe is fixedly connected to a connector, and a protective sleeve is screwed onto its exterior.

[0011] As a further optimization, in order to hinge the trough body to the garbage truck on the side near the slope window, the trough body and the container body are rotated around the hinge end by a lifting cylinder to achieve electric unloading.

The garbage truck control system controls the electromagnetic latch to open, and the container body is lifted and tilted to unload. The compressed waste is discharged from the sloping window, eliminating the need for manual control of the cover and achieving a more automated unloading process. Attached Figure Description

[0022] Furthermore, in the following description of this utility model, unless otherwise stated, "multiple", "multiple groups", or "multiple roots" means two or more.

[0023] Please see Figure 1-5The present invention provides a technical solution: an electric self-unloading garbage truck body with compression function. The body body 1 mainly includes a body 11 for containing garbage. At the rear end of the body 11, i.e. the unloading end, an inclined slope window 12 is provided. This window serves as both the garbage input and unloading outlet. The slope design facilitates the feeding of garbage. A cover plate 13 is hinged to the upper edge of the slope window 12 and can be flipped open and closed outward. When the cover plate 13 is fastened, it covers the outside of the slope window 12.

[0024] To ensure that the cover plate 13 will not be accidentally opened due to internal pressure during garbage compression and transportation, an electromagnetic latch lock 9 is installed on the front and rear sides of the non-hinged end of the cover plate 13, between the edge of the corresponding slope window 12 on the side wall of the container body 11. When the electromagnetic latch lock 9 is energized and locked, the cover plate 13 can be firmly locked in the closed position.

[0025] To achieve automated unloading, a pressure triggering structure 8 is installed on the inner bottom surface of the cover plate 13. Inside the container body 11, at the front end away from the slope window 12, a compression mechanism 5 is installed to compress the loose garbage put into the container body 11 and increase the loading capacity. The compression mechanism 5, the pressure triggering structure 8, and the electromagnetic latch lock 9 are all connected to the power supply system and control system of the garbage truck through circuits. The power supply system and control system of the garbage truck are conventional configurations in this field and therefore are not described in detail in this article. The garbage truck control system receives signals from the pressure triggering structure 8 and controls the operation of the electromagnetic latch lock 9 and the compression mechanism 5 accordingly.

[0026] Specifically, during the compression process, when the pressure on the pressure trigger structure 8 reaches a predetermined value, a signal is transmitted to the garbage truck control system. The garbage truck control system controls the electromagnetic latch lock 9 to open and simultaneously controls the compression mechanism 5 to stop working. As the container body 1 is lifted and flipped for unloading, the compressed garbage is discharged from the slope window 12 without the need for manual control of the cover plate 13, thus achieving a more automated unloading process.

[0027] like Figure 4As shown, the pressure triggering structure 8 is a key sensor component that triggers automatic opening and unloading. It includes a baffle 81 fixed to the bottom surface of the cover plate 13. Between the baffle 81 and the bottom surface of the cover plate 13, a pressure sensor 83 and a rubber ring 82 surrounding the pressure sensor 83 are fixed. The rubber ring 82 plays a sealing and protective role, preventing leachate from corroding the pressure sensor 83. Multiple pressure sensors 83 are evenly distributed on the baffle 81 and connected to the circuit in parallel, and then electrically connected to the garbage truck control system. When the compression mechanism 5 compresses the garbage, the garbage exerts upward pressure on the cover plate 13. This pressure is transmitted to the pressure sensor 83 through the baffle 81. When the pressure value reaches the preset threshold of the control system, indicating that the garbage has been compressed to the predetermined density, the garbage truck control system issues a command to control the operation of the electromagnetic latch lock 9 and the compression mechanism 5.

[0028] Furthermore, the wiring of the pressure sensor 83 passes through the reserved hole on the rubber ring 82. The size of the reserved hole is slightly smaller than the outer diameter of the cable to prevent the leakage liquid from entering between the reserved hole and the cable. Understandably, the cable located on the outside of the cover plate 13 has sufficient length to allow for the hinge movement of the cover plate 13.

[0029] like Figure 2 As shown, the compression mechanism 5 is used to compress garbage. It mainly includes a hydraulic cylinder 52 and a hydraulic system 51, such as a hydraulic pump station. The hydraulic cylinder 52 is vertically fixed at one end of the box body 11 away from the slope window 12. The piston rod of the hydraulic cylinder 52 passes through the box body 11 and is connected to a pressure plate 53. The hydraulic system 51 is connected to the inlet and outlet of the hydraulic cylinder 52 through oil pipes to provide power to the hydraulic cylinder 52. When working, the hydraulic system 51 drives the piston rod of the hydraulic cylinder 52 to extend, pushing the pressure plate 53 to move towards the slope window 12 at the rear end of the box body, thereby horizontally compressing the garbage.

[0030] Furthermore, the hydraulic system 51 is fixed to the outer wall of the box body 11 away from the slope window 12, and the lower end of the hydraulic system 51 is in contact with the frame of the garbage truck, using the frame to share the weight. Understandably, in this design, there is a gap between the container body 11 and the front of the garbage truck for the installation of the hydraulic system 51 and the hydraulic cylinder 52.

[0031] like Figure 3As shown, to further optimize the compression effect and improve durability, the pressure plate 53 adopts a modular design, which includes a flat plate 531 fixed to the piston rod of the hydraulic cylinder 52. On the side of the flat plate 531 facing the waste, a wedge-shaped groove 532 is formed along its length. A steel plate 533 is slidably inserted into the wedge-shaped groove 532 through a wedge-shaped slider 534 integrally formed on its back, so that the steel plate 533 can be installed on the flat plate 531 as a wear-resistant liner. The steel plate 533 is preferably made of corrosion-resistant stainless steel. On its working surface, there are evenly formed arched protrusions 535. These protrusions can better crush and squeeze the waste during compression, while improving the surface structural strength and wear resistance. When the steel plate 533 is severely worn, it can be easily slid off the flat plate 531 for replacement.

[0032] like Figure 2 As shown, in order to collect leachate generated during the garbage compression process and avoid environmental pollution, a leachate collection tank 3 is set below the tank body 11. Specifically, the bottom surface of the tank body 11 is replaced with a mesh plate 32 with dense through holes. The leachate can leak through the mesh holes. A tank body 31 is fixedly connected below the mesh plate 32, and its top is connected to the bottom of the tank body 11 for collecting leachate. A discharge pipe 33 with a valve is installed at the lower end of the outer wall of the tank body 31, and the valve can be opened periodically to discharge the accumulated leachate.

[0033] like Figure 5 As shown, to prevent impurities in the leachate from depositing and hardening inside the tank body 31, backwashing components 4 are installed on both the left and right sides of the bottom surface of the tank body 31. Each backwashing component 4 includes a connecting pipe 41 that communicates with the bottom surface of the tank body 31. The upper end of the connecting pipe 41 branches off to the left and right sides through a tee pipe 44. The lower end of the connecting pipe 41 is connected to a connector 42, which is protected by a protective sleeve 43. When flushing is required, an external high-pressure water source can be connected to the connector 42. The high-pressure water is sprayed out from the branch pipes on both sides through the tee pipe 44, backwashing the inner wall of the tank body 31 to achieve cleaning.

[0034] Please see Figure 1 and Figure 2 A lifting cylinder seat 6 is fixed on the bottom surface of the trough 31 away from the slope window 12, for hinged connection with the lifting cylinder on the garbage truck chassis. A box body tilting hinge seat 7 is fixed on the bottom surface of the trough 31 near the slope window 12, for hinged connection with the tilting hinge support on the garbage truck chassis. When unloading, the lifting cylinder pushes the lifting cylinder seat 6, causing the entire box body 1 to tilt backward around the hinge point of the box body tilting hinge seat 7. The slope window 12 tilts downward accordingly, and the garbage slides out under the action of gravity, realizing the electric self-unloading function of the garbage truck.

[0035] To ensure stability during lifting and transportation, two box support plates 61 are fixed along the length of the box body on the bottom surface of the tank body 31, located on the front and rear sides of the lifting cylinder seat 6, to provide stable support when the box body is horizontal. To enhance the structural strength of the housing 11, several longitudinal reinforcing ribs 2 are integrally formed on its top surface along the length direction, and several transverse reinforcing ribs 21 are integrally formed on its front and rear side walls along the height direction. In addition, protective pillars 22 are fixed at the four corners of the front exterior of the housing 11. Together, they form a protective frame to protect the hydraulic system 51 and hydraulic cylinder 52 located on the outer wall of the housing from collision damage.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
