Description

Technical Field

[0001] This utility model relates to the technical field of municipal solid waste treatment devices, specifically to a municipal solid waste compression and transfer device. Background Technology

[0002] With the acceleration of urbanization, the amount of domestic waste generated continues to rise. Efficient treatment and transportation have become important issues in urban environmental management. Domestic waste compression and transfer devices can significantly improve transportation efficiency and reduce transportation costs by compressing and reducing the volume of waste, making them key equipment in the waste collection and transportation system.

[0003] Currently, most waste compression and transfer devices on the market use hydraulic cylinders to drive corresponding lower plates to compress household waste. However, these devices typically have openings on both sides for unloading. In practice, a pusher assembly is usually installed on one side of the opening to push the compressed waste outwards through the other side. While this method works, it is cumbersome, occupies horizontal space, and is inconvenient for users. Therefore, we propose a new household waste compression and transfer device. Utility Model Content

[0004] The purpose of this invention is to provide a municipal solid waste compression and transfer device to address the deficiencies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A municipal solid waste compression and transfer device includes a main frame base plate installed on an external waste transfer vehicle. The main frame base plate has a central material discharge hole. A storage box is fixedly installed on the upper surface of the main frame base plate by two front and rear support frames. A sealing plate for sealing operation is provided at the bottom of the storage box. The sealing plate is driven by a first hydraulic cylinder. A fixing frame is fixedly installed on the top surface of the storage box. Two symmetrical second hydraulic cylinders are fixedly installed on the top plate of the fixing frame. A lower pressure plate is detachably installed at the end of the telescopic shaft of the two second hydraulic cylinders. The lower pressure plate is located inside the storage box and is slidably connected to the storage box.

[0007] Preferably, after the main chassis base plate is installed on the external vehicle body, the distance between the main chassis base plate and the ground is greater than or equal to the height of the storage box;

[0008] This setting allows the compressed waste to fall normally from the central discharge port.

[0009] Preferably, the two side plates of the support frame are fixedly installed on the main base plate of the vehicle frame and the storage box, respectively. After the sealing plate is unfolded, the compressed waste in the storage box falls out along the bottom of the central discharge hole.

[0010] Preferably, a bolt plate is fixedly installed at the end of the telescopic shaft of the second hydraulic cylinder, and the lower pressure plate is detachably installed on the bottom surface of the bolt plate.

[0011] Preferably, a feeding hopper is fixedly installed on one side plate of the storage box, and the feeding hopper is set at an upward inclination of 45°~60°.

[0012] Preferably, a U-shaped frame is fixedly installed on the end face of the sealing plate, an end plate is fixedly installed on the top surface of the U-shaped frame, a steel plate is fixedly installed at the end of the telescopic shaft of the second hydraulic cylinder, and the end plate is detachably installed on the side of the steel plate.

[0013] Preferably, guide rails are fixedly installed on both the left and right sides of the bottom box of the storage box, and a sliding groove is provided in the guide rail along the length of the guide rail. Sliding strips are fixedly installed on the top surfaces of both sides of the sealing plate, and the sliding strips are located in the sliding grooves and are slidably connected to the sliding grooves.

[0014] Preferably, both the slide bar and the slide groove have T-shaped cross-sections, and the dimensions of the slide bar are adapted to the dimensions of the slide groove;

[0015] The above two settings make the structure of the sealing plate more stable.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model uses a first hydraulic cylinder to drive the sealing plate to slide along the guide rail, thereby opening and closing the bottom of the storage box. Combined with the central discharge hole on the main base plate of the frame, the compressed waste can fall directly from the bottom to complete the unloading, replacing the traditional method of pushing material through openings on both sides. This avoids occupying horizontal space and achieves vertical unloading, thus simplifying operation and saving space.

[0018] 2. This utility model uses a second hydraulic cylinder to drive the lower pressure plate to slide up and down in the storage box, thereby vertically compressing the waste. The inclined design of the feed hopper facilitates waste input, and the bolt plate facilitates the disassembly and maintenance of the lower pressure plate, achieving efficient compression and convenient feeding, thus improving compression efficiency and equipment maintenance convenience.

[0019] 3. This utility model enhances the stability of the sealing plate during sliding by using a T-shaped sliding bar and a sliding groove. The U-shaped frame and end plate ensure a firm connection between the first hydraulic cylinder and the sealing plate. The support frame provides stable support for the storage box. The overall structure improves the reliability of the device's operation and achieves the effect of adapting to high-frequency garbage compression and transfer work. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Please see Figures 1-4This utility model provides a technical solution: a municipal solid waste compression and transfer device, including a main frame base plate 1 installed on an external waste transfer vehicle. The main frame base plate 1 is provided with a central discharge hole 10. A storage box 12 is fixedly installed on the upper surface of the main frame base plate 1 by two front and rear support frames 11. A sealing plate 23 for sealing operation is provided at the bottom of the storage box 12. The sealing plate 23 is driven by a first hydraulic cylinder 2. A fixing frame 3 is fixedly installed on the top surface of the storage box 12. Two symmetrical second hydraulic cylinders 30 are fixedly installed on the top plate of the fixing frame 3. A lower pressure plate 32 is detachably installed at the end of the telescopic shaft of the two second hydraulic cylinders 30. The lower pressure plate 32 is located inside the storage box 12 and is slidably connected to the storage box 12, so as to realize the compression operation from top to bottom and the unloading operation from the central discharge hole 10, which is convenient to use.

[0030] In this embodiment, after the main chassis plate 1 is installed on the external vehicle body, the distance between the main chassis plate 1 and the ground is greater than or equal to the height of the storage box 12, ensuring that the compressed waste can fall smoothly from the central discharge hole 10, avoiding obstruction of unloading due to insufficient space, and ensuring a smooth unloading process.

[0031] Specifically, the two side plates of the support frame 11 are fixedly installed on the main base plate 1 of the vehicle frame and the storage box 12 respectively. After the sealing plate 23 is unfolded, the compressed waste in the storage box 12 falls out along the bottom of the central discharge hole 10, which enhances the stability of the storage box 12 installation. With the sealing plate 23 unfolded, the waste is guided to fall out from the central discharge hole 10, so as to achieve stable unloading.

[0032] like Figure 2 As shown, a bolt plate 31 is fixedly installed at the end of the telescopic shaft of the second hydraulic cylinder 30. The lower pressure plate 32 is detachably installed on the bottom surface of the bolt plate 31 by multiple fastening bolts, so that the lower pressure plate 32 can be detached and installed, which facilitates the disassembly, replacement and cleaning of the lower pressure plate 32 and improves the convenience of equipment use.

[0033] like Figure 1 As shown, a feeding hopper 14 is fixedly installed on one side plate of the storage box 12. The feeding hopper 14 is set at an upward tilt of 45°~60° to facilitate the smooth input of garbage into the storage box 12, reduce the scattering of garbage during disposal, and improve the feeding efficiency.

[0034] In addition, a U-shaped frame 22 is fixedly installed on the end face of the sealing plate 23, and an end plate 21 is fixedly installed on the top surface of the U-shaped frame 22. A steel plate 20 is fixedly installed at the end of the telescopic shaft of the second hydraulic cylinder 30. The end plate 21 is detachably installed on the side of the steel plate 20 by multiple fastening bolts, so that the sealing plate 23 is firmly connected to the first hydraulic cylinder 2, and at the same time, it is convenient for later disassembly and maintenance.

[0035] It is worth noting that guide rails 13 are fixedly installed on both the left and right sides of the bottom of the storage box 12. The guide rails 13 are provided with sliding grooves 131 arranged along the length of the guide rails 13. Sliding strips 24 are fixedly installed on the top surfaces of both sides of the sealing plate 23. The sliding strips 24 are located in the sliding grooves 131 and are slidably connected to the sliding grooves 131, providing guidance for the sliding of the sealing plate 23 and ensuring its smooth movement.

[0036] It is worth noting that the cross-sections of both the slide bar 24 and the slide groove 131 are T-shaped, and the size of the slide bar 24 is matched with the size of the slide groove 131 to prevent the sealing plate 23 from detaching from the guide rail 13 when sliding, thereby further enhancing the stability of the movement of the sealing plate 23 and the reliability of the structure.

[0037] Finally, it should be noted that the first hydraulic cylinder 2, the second hydraulic cylinder 30, the corresponding control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0038] When using the household waste compression and transfer device of this utility model, the main base plate 1 of the frame is installed on the external waste transfer vehicle, ensuring that the distance between it and the ground is not less than the height of the storage box 12. Waste is put into the storage box 12 through the feeding hopper 14. At this time, the sealing plate 23 is in a closed state, and the T-shaped slide bar 24 is stuck in the slide groove 131 of the guide rail 13.

[0039] The second hydraulic cylinder 30 is activated, which drives the lower pressure plate 32 at the bottom of the bolt plate 31 to slide downward in the storage box 12 to compress the waste;

[0040] Start the first hydraulic cylinder 2, and pull the sealing plate 23 along the guide rail 13 through the steel plate 20, end plate 21 and U-shaped frame 22 to open the bottom of the storage box 12. At this time, the telescopic shaft of the second hydraulic cylinder 30 continues to extend, so that the compressed garbage is squeezed out through the central discharge hole 10 and falls to the corresponding transfer position. After the unloading is completed, the first hydraulic cylinder 2 pushes the sealing plate 23 to reset and close, and repeats the above steps to perform the next round of operation.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
