Technical Field

[0001] This utility model relates to the field of waste compression station technology, and more specifically to a waste pre-compression system based on a waste compression station. Background Technology

[0004] In the prior art, including the aforementioned patent, the compressed waste is moved by moving the cleaning frame to facilitate the processing of the compressed waste. This common processing method results in a large volume of uncompressed waste when it is disposed of, especially for empty plastic bottles. Therefore, within the fixed volume, the proportion of empty bottles leads to a small number of bottles being compressed at one time, and the waste compression station does not fully utilize its compressible capacity, resulting in low compression efficiency.

[0011] Preferably, the bottom of the compression chamber is provided with an inclined guide groove, and a vibrating plate is slidably disposed in the inclined guide groove.

[0012] Preferably, the compression box is provided with a limiting platform, and the insertion rod provided on the vibration plate is slidably disposed on the limiting platform.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5As shown, a waste pre-compression system based on a waste compression station includes a compression box 1 and a compression chamber 11 therein. A feeding hopper 2 is fixedly installed on the compression box 1, and a main compression roller 41 and an auxiliary compression roller 42 rotating in opposite directions are provided in the feeding hopper 2. The auxiliary compression roller 42 is movably disposed in a groove 22 opened on the feeding hopper 2 and maintains a predetermined distance from the main compression roller 41. By feeding waste into the feeding hopper 2, the waste is pre-compressed by the opposing rotation of the main compression roller 41 and the auxiliary compression roller 42. The compressed waste then slides down the feeding hopper 2 into the compression chamber 11 for further compression. By moving the auxiliary compression roller 42 within the groove 22, the distance between the main compression roller 41 and the auxiliary compression roller 42 can be adjusted to adjust the degree of pre-compression.

[0027] As a further technical solution provided by this utility model, an auxiliary gear 44 is rotatably provided on the feeding hopper 2, and the auxiliary gear 44 meshes with the main gear 43 fixedly installed at the first end of the main extrusion roller 41. The output end of the main motor 4 fixedly installed on the feeding hopper 2 is fixedly installed at the second end of the main extrusion roller 41.

[0028] Specifically, such as Figure 2 As shown, the main motor 4 drives the main extrusion roller 41 to rotate for pre-compression of waste, and then the main gear 43 and auxiliary gear 44 on the main extrusion roller 41 mesh to drive the auxiliary gear 44 to rotate.

[0029] Furthermore, a slider 64 is slidably arranged between the baffles 23 symmetrically arranged on the feeding hopper 2. The auxiliary extrusion roller 42 is rotatably arranged on the slider 64, and the first single-rail wheel 63 fixedly installed at the end of the auxiliary extrusion roller 42 and the double-rail wheel 6 fixedly installed at the end of the shaft of the auxiliary gear 44 are driven by a belt.

[0030] Specifically, the slider 64 slides between the baffles 23 to improve the stability of the auxiliary extrusion roller 42 during sliding. The main gear 43 and the auxiliary gear 44 mesh to make the double-rail pulley 6 and the main extrusion roller 41 rotate in opposite directions. The double-rail pulley 6 and the first single-rail pulley 63 are driven by a belt so that the double-rail pulley 6 drives the first single-rail pulley 63 to rotate in the same direction, thereby enabling the main extrusion roller 41 and the auxiliary extrusion roller 42 to rotate in opposite directions.

[0031] Furthermore, a U-shaped guide frame 24 is slidably mounted on the feeding hopper 2, and a buffer spring 66 is fixedly installed between the adjusting block 65 slidably mounted inside the U-shaped guide frame 24 and the U-shaped guide frame 24. A second monorail wheel 62 is fixedly mounted at the end of the shaft rotatably mounted on the adjusting block 65, and the first monorail wheel 63, the second monorail wheel 62 and the double-rail wheel 6 are driven by a belt.

[0032] Specifically, such as Figure 5As shown, when the main extrusion roller 41 and the auxiliary extrusion roller 42 extrude solid materials such as hard metals, the extrusion and counter-force between the main extrusion roller 41 and the auxiliary extrusion roller 42 forces the auxiliary extrusion roller 42 to move away from the main extrusion roller 41. At this time, the movement of the auxiliary extrusion roller 42 causes the adjusting block 65 to move upward and the buffer spring 66 to deform and store force. Thus, under the movement of the auxiliary extrusion roller 42 and the buffer deformation of the buffer spring 66, a certain amount of extrusion force is maintained on plastic bottles and the like. For solid waste, the deformation of the buffer spring 66 and the movement of the auxiliary extrusion roller 42 allow the waste to pass over the main extrusion roller 41 and the auxiliary extrusion roller 42 and fall into the compression chamber 11. Compared with the extrusion rollers at fixed points, this avoids the waste from being unable to be compressed and blocking the extrusion rollers, while ensuring that the waste receives a certain amount of extrusion force. Furthermore, during the extrusion process, the first monorail roller 63, the second monorail roller 62, and the double-rail roller 6 always maintain transmission so that the auxiliary extrusion roller 42 keeps rotating to extrude waste.

[0033] Furthermore, a compression plate 31 is movably arranged above the compression chamber 11 in the compression box 1. Guide rods 3 symmetrically fixed on the compression plate 31 are slidably arranged on the compression box 1. A hydraulic cylinder 32 is fixedly installed between the compression plate 31 and the compression box 1. A discharge plate 33 is movably arranged on one side of the inner wall of the compression chamber 11 in the compression box 1.

[0034] Specifically, the compression plate 31 is moved down by the hydraulic cylinder 32 to compress the waste in the compression chamber 11, while the discharge plate 33 is flipped to discharge the compressed waste.

[0035] Furthermore, an inclined guide groove 12 is provided at the bottom of the compression chamber 11, and a vibrating plate 53 is slidably arranged in the inclined guide groove 12.

[0036] Specifically, such as Figure 4 As shown, the vibrating plate 53 slides in the inclined guide groove 12, so that the vibrating plate 53 can move in the inclined upward direction, thereby realizing the vertical and horizontal movement of the garbage in the compression chamber 11 to disperse the garbage, thereby improving the dispersion effect of the garbage.

[0037] Furthermore, a limiting platform 13 is provided on the compression box 1, and the insertion rod 54 provided on the vibration plate 53 is slidably disposed on the limiting platform 13. A vibration spring 55 is fixedly installed between the bottom of the vibration plate 53 and the compression box 1, and the first end of the rocker arm 52 hinged on the compression box 1 is movably disposed at the bottom of the vibration plate 53.

[0038] Specifically, by pressing down the second end of the rocker arm 52, the first end of the rocker arm 52 pushes against the bottom of the vibrating plate 53, causing the vibrating plate 53 to move along the inclined guide groove 12 in an upward direction to shake the material. At the same time, the vibration spring 55 deforms and stores force, and when the second end of the rocker arm 52 moves upward, the vibration spring 55 pulls the vibrating plate 53 to quickly return to its original position, so that the vibrating plate 53 hits the limiting table 13 to produce the effect of vibrating and shaking the material.

[0039] Furthermore, the pressure rod 51, which is slidably disposed inside the compression box 1, is movably disposed at the second end of the rocker arm 52, and the cam 45, which is rotatably disposed on the feeding hopper 2, is movably disposed on the pressure plate 5, which is fixedly installed at the top of the pressure rod 51.

[0040] Specifically, the cam 45 rotates on the pressure plate 5, thereby driving the pressure rod 51 to move vertically. When the pressure rod 51 is squeezed downward by the cam 45, the pressure rod 51 presses down on the second end of the rocker arm 52, causing the first end of the rocker arm 52 to push the vibrating plate 53 to move upward along the inclined guide groove 12. When the protrusion on the cam 45 moves away from the pressure plate 5 and stops squeezing the pressure rod 51, the vibration spring 55 resets the vibrating plate 53 to move downward and reset. Thus, under the action of multiple equally spaced protrusions on the cam 45 and in conjunction with the vibration spring 55, the vibrating plate 53 is vibrated and shaken to achieve the effect of shaking and shaking the material.

[0041] Furthermore, a third monorail pulley 61 is fixedly mounted on one end of the cam 45 shaft, and the third monorail pulley 61 and the double rail pulley 6 are driven by a belt.

[0042] Specifically, the rotation of the double-rail wheel 6 drives the auxiliary extrusion roller 42 to rotate, and at the same time, it drives the cam 45 to rotate.

[0043] Furthermore, a limit plate 21 is fixedly installed on the inner wall of the delivery bucket 2.

[0044] Specifically, the limiting plate 21 is used to ensure that the waste falls more accurately between the main extrusion roller 41 and the auxiliary extrusion roller 42.

[0045] Working principle: The main extrusion roller 41 and the auxiliary extrusion roller 42 rotate in opposite directions to compress pre-compress waste. When the main extrusion roller 41 and the auxiliary extrusion roller 42 compress hard metal or other solids, the compression and counter-pushing force between the main extrusion roller 41 and the auxiliary extrusion roller 42 forces the auxiliary extrusion roller 42 to move away from the main extrusion roller 41. At this time, the movement of the auxiliary extrusion roller 42 causes the adjusting block 65 to move upward and the buffer spring 66 to deform and store energy. Thus, under the movement of the auxiliary extrusion roller 42 and the buffer deformation of the buffer spring 66, a certain amount of extrusion force is maintained on plastic bottles and the like. For solid waste, the deformation of the buffer spring 66 and the movement of the auxiliary extrusion roller 42 allow the waste to pass over the main extrusion roller 41 and the auxiliary extrusion roller 42 and fall into the compression chamber 11. Compared with the extrusion rollers at fixed points, this method can avoid the waste being unable to be compressed and thus blocking the extrusion rollers, while ensuring that the waste receives a certain amount of extrusion force. During the extrusion process, the first single-track roller 63, the second single-track roller 62, and the double-track roller 6 maintain continuous transmission to keep the auxiliary extrusion roller 42 rotating to extrude waste. The rotation of the double-track roller 6 drives the cam 45 to rotate, which in turn moves the cam 45 onto the pressure plate 5, causing the pressure rod 51 to move vertically. When the pressure rod 51 is extruded and moves downward by the cam 45, it presses down on the second end of the rocker arm 52, causing the first end of the rocker arm 52 to push the vibrating plate 53 to move upward along the inclined guide groove 12. When the protrusion on the cam 45 moves away from the pressure plate 5 and stops extruding the pressure rod 51, the vibration spring 55 resets the vibrating plate 53, causing it to move downward and reset. The action of multiple equally spaced protrusions on the cam 45, combined with the vibration spring 55, achieves the effect of shaking and vibrating the material on the vibrating plate 53.

Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
