Description

Technical Field

[0001] This utility model belongs to the technical field of garbage compressors, specifically a household waste compressor. Background Technology

[0002] A garbage compactor is a device specifically designed for compressing and processing garbage. When processing household waste, a garbage compactor is used to compress the garbage, which not only reduces the space occupied by the garbage, but also effectively reduces the amount of garbage and the cost of garbage disposal. When compressing garbage, the door of the garbage compactor is closed, and then the garbage is put into the machine body through the preset channel above the door. After the garbage is put in, the hydraulic cylinder is activated, and its power pushes the pressure plate downward to compress the garbage inside the machine body.

[0003] In existing technologies, however, during actual processing, when many small, lightweight waste items such as cardboard boxes and milk cartons are placed into and piled up inside the machine, some of the piled-up waste tends to overflow from the feeding channel above the door panel. When the subsequent pressure plate moves downward to compress the waste, these overflowing small cardboard boxes and milk cartons are excluded from the compression process. To achieve effective compression of all waste, it is necessary to rely on hydraulic cylinders to drive the pressure plate to move up and down repeatedly. Moreover, after each upward movement of the pressure plate, the operator needs to manually push the overflowing waste back into the machine using special tools. This method greatly increases the working danger of the operator, as the operator needs to be in close contact with the operating equipment parts. In addition, the frequent manual intervention severely slows down the overall waste compression process, resulting in a significant reduction in waste compression efficiency.

[0004] In existing technology, when compressing garbage, the door panel on the machine body is closed, and then the garbage is put into the machine body through the channel above the door panel. Then, the hydraulic cylinder is activated to push the pressure plate downward to compress the garbage. However, when some small waste paper boxes and milk cartons are put into the machine body for compression, if too many small waste paper boxes and milk cartons are put in, they are easy to overflow from the door panel. At this time, if the pressure plate moves downward, the small waste paper boxes and milk cartons that overflow outward cannot be compressed. It is necessary to drive the pressure plate up and down repeatedly through the hydraulic cylinder. After the pressure plate moves upward, personnel need to use tools to push the small waste paper boxes and milk cartons that overflow outward back into the machine body to push them back into the machine body. This not only increases the danger of personnel operation, but also causes the garbage compression efficiency to decrease. To address this issue, we propose a household waste compressor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a municipal solid waste compressor, comprising a body, a door panel, and a pressure plate, wherein a pre-push-in mechanism is provided on the front side of the body, the pre-push-in mechanism comprising:

[0007] An upper plate is mounted on the machine body via a rotating shaft. An L-shaped push plate is slidably mounted on the back of the upper plate. A central column is fixedly mounted on the front of the upper plate, and a rod is fixedly mounted at the end of the central column.

[0008] A rod frame and a drive motor are fixedly installed on the front side of the upper plate, and a lead screw is fixedly installed at the working end of the drive motor. A nut seat is installed on the outside of the lead screw.

[0009] Preferably, a fixing plate is fixedly provided on the free end surface of the upper plate, a locking stud is slidably provided inside the fixing plate, and a screw hole is provided on the surface of the machine body;

[0010] An L-shaped frame is fixedly installed on the top of the nut seat, and a sliding frame is fixedly installed on one side of the nut seat.

[0011] Preferably, the end of the rod passes through the interior of the L-shaped frame, and two sets of sliding rings are provided on the outside of the rod. The interior of the sliding rings is connected to a locking screw by a thread.

[0012] Preferably, the pre-insertion mechanism further includes a puncture assembly, which includes multiple sets of needles slidably disposed on the upper plate and the L-shaped push plate, and a spiral frame is fixedly disposed at the end of the L-shaped frame.

[0013] Preferably, the nut seat is provided with a cleaning component for removing foreign matter adhering to the outer surface of the lead screw. The cleaning component includes two sets of ring tubes and two sets of ring brushes disposed outside the nut seat, and the inner wall of the ring tubes has multiple sets of blow holes.

[0014] Preferably, a pipeline is fixedly installed on the nut seat, and the outer walls of the ring pipe and the ring brush are fixed on the pipeline. A blower is also fixedly installed on the nut seat.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) This utility model, through its pre-push mechanism, after the door panel is closed, rotates the upper plate clockwise to close it, causing the L-shaped push plate on the back to move. This promptly pushes small pieces of waste that have accumulated and overflowed above the door panel into the machine body, preventing the waste from overflowing and becoming uncompressible. Simultaneously, before the L-shaped push plate is pushed in, the drive motor causes the needles to move into the machine body first, piercing small waste paper boxes, milk cartons, and other waste. This squeezes out the air inside the waste, effectively reducing its volume and increasing its density, making the subsequent compression process more efficient. The mechanism controls the time it takes for the L-shaped push plate to move and compress the waste after the needles pierce it. Different textures and accumulation states of waste can be adapted to the corresponding compression rhythm.

Detailed Implementation

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This utility model provides a technical solution: a municipal solid waste compressor, including a body 100, a door panel 103, and a pressure plate 102. The free end of the door panel 103 is fixedly connected to the body 100 by a latch, facilitating the opening of the door panel 103. The right side of the door panel 103 is rotatably connected to the body 100 by a rotating shaft. A pre-push-in mechanism is provided on the front of the body 100, the pre-push-in mechanism including:

[0031] The upper plate 200, which is mounted on the machine body 100, is rotated by a pivot. An L-shaped push plate 203 is slidably mounted on the back of the upper plate 200. The needle 211 first extends to puncture the garbage, and then the L-shaped push plate 203 moves to squeeze and compress the garbage. A central column 206 is fixedly mounted on the front of the upper plate 200 of the L-shaped push plate 203, and a rod 214 is fixedly mounted at the end of the central column 206.

[0032] A rod frame 209 and a drive motor 215 are fixedly installed on the front of the upper plate 200. When the working end of the drive motor 215 rotates forward, it can drive the needle 211 and the L-shaped push plate 203 to move inward toward the machine body 100. When the working end of the drive motor 215 rotates in reverse, it can drive the needle 211 and the L-shaped push plate 203 to move away from the machine body 100. A lead screw 207 is fixedly installed on the working end of the drive motor 215. The end of the lead screw 207 is rotatably connected to the rod frame 209. A nut seat 208 is provided on the outside of the lead screw 207.

[0033] A fixing plate 202 is fixedly installed on the free end surface of the upper plate 200. A locking stud 201 is slidably installed inside the fixing plate 202. The locking stud 201 can fix the free end of the upper plate 200 to the machine body 100. A screw hole is opened on the surface of the machine body 100. The working end of the locking stud 201 extends into the screw hole. A fixing ring is fixedly installed on the outside of the locking stud 201.

[0034] An L-shaped frame 210 is fixedly installed on the top of the nut seat 208. The end of the L-shaped frame 210 is fixedly connected to the upper plate 200. A sliding frame 216 is fixedly installed on one side of the nut seat 208. The sliding frame 216 can slide back and forth on the rod 209.

[0035] The end of the rod 214 passes through the interior of the L-shaped frame 210. Two sets of sliding rings 213 are provided on the outside of the rod 214. The inside of the sliding rings 213 is connected to a locking screw 212 by a thread. The working end of the locking screw 212 extends to the surface of the rod 214. During use, the distance between the two sets of sliding rings 213 can be adjusted, thereby adjusting the time when the L-shaped push plate 203 moves and squeezes the garbage after the needle 211 punctures the garbage. This allows the operator to flexibly adjust the distance between the two sets of sliding rings 213 according to the actual situation of the garbage, and control the time when the L-shaped push plate 203 starts to move after the needle 211 punctures the garbage. Garbage of different textures and accumulation states can be adapted to the corresponding compression rhythm, which enhances the adaptability of the equipment to various types of domestic waste and ensures that a good compression effect can be achieved under various conditions.

[0036] The pre-insertion mechanism also includes a piercing assembly, which includes multiple sets of needles 211 slidably disposed on the upper plate 200 and the L-shaped push plate 203. A loop frame 205 is fixedly disposed at the end of the L-shaped frame 210, and the needles 211 are fixed above the loop frame 205. The upper plate 200 and the L-shaped push plate 203 are both provided with through holes for the needles 211 to pass through. A magnet 204 is embedded in the front of the upper plate 200, and an iron plate 218 is installed on the right side of the body 100. When the magnet 204 and the iron plate 218 are attracted together, they can attract and limit the opening of the upper plate 200.

[0037] This invention utilizes a pre-push mechanism. After the door panel 103 is closed, the upper plate 200 is rotated clockwise to close it, causing the L-shaped pusher plate 203 on the back to move. This promptly pushes small pieces of waste that have accumulated and overflowed above the door panel 103 into the machine body 100, preventing waste from overflowing and becoming uncompressible. Simultaneously, before the L-shaped pusher plate 203 is pushed in, the drive motor 215 moves the piercing needles 211 into the machine body 100 to puncture small waste such as cardboard boxes and milk cartons, squeezing out internal air, effectively reducing waste volume, increasing its density, and making the subsequent compression process more efficient. The mechanism controls the time it takes for the L-shaped pusher plate to move and compress the waste after the piercing needles 211 puncture it. Different textures and accumulation states of waste can be adapted to different compression rhythms.

[0038] Example 2

[0039] Please refer to Example 1. Figures 1-7The nut seat 208 is provided with a cleaning component for removing foreign matter attached to the outer surface of the lead screw 207. The cleaning component includes two sets of ring tubes 300 and two sets of ring brushes 301 provided outside the nut seat 208. Multiple sets of blow holes are opened on the inner wall of the ring tubes 300.

[0040] A pipe 302 is fixedly installed on the nut seat 208. The outer walls of the ring pipe 300 and the ring brush 301 are fixed on the pipe 302. A blower 303 is also fixedly installed on the nut seat 208. The pipe 302 is connected to the ring pipe 300.

[0041] This utility model, through the designed cleaning component, with the ring tube 300 and the ring brush 301 working together, can effectively and promptly remove dust and foreign objects from the outer surface of the lead screw 207 during the movement of the nut seat 208, keeping the surface of the lead screw 207 clean, greatly reducing the wear between the lead screw 207 and the nut seat 208, and ensuring the stable and continuous operation of the equipment.

[0042] In this embodiment, a hydraulic cylinder 101 is fixedly installed on the machine body 100. The working end of the hydraulic cylinder 101 is fixedly connected to the pressure plate 102. Two sets of limiting rods are fixedly installed on the top of the pressure plate 102, and the top of the limiting rods extends to the outer side of the top of the machine body 100.

[0043] In this embodiment, a hydraulic rod 105 is fixedly installed on the back of the machine body 100, and a rear push plate 104 is fixedly installed at the working end of the hydraulic rod 105.

[0044] Working principle and usage process of this utility model:

[0045] In use, the door panel 103 is closed, and small waste paper boxes, milk cartons, and other trash are placed into the machine body 100 through the upper channel of the door panel 103. At this time, some of the small waste paper boxes and milk cartons accumulated inside the machine body 100 overflow outwards. Then, the free end of the upper plate 200 is turned clockwise to close it. At this time, the magnet 204 on the upper plate 200 is no longer magnetically attracted to the iron plate 218 on the machine body 100. After closing the upper plate 200, the working end of the locking stud 201 is passed through the inside of the fixing plate 202 and screwed into the corresponding screw hole on the machine body 100. Then, the fixing ring on the outside of the locking stud 201 contacts the front of the fixing plate 202, and the locking stud 201 is tightened. This tightens the fixing plate 202. 2. Once fixed to the body 100, the upper plate 200 is secured. When the upper plate 200 is rotated clockwise and closed, the L-shaped push plate 203 on the back of the upper plate 200 moves. The L-shaped push plate 203 then pushes the small waste paper boxes, milk cartons, and other waste materials that have accumulated and overflowed above the door panel 103 into the body 100. After the upper plate 200 is closed, the drive motor 215 is started. The working end of the drive motor 215 rotates slowly, causing the lead screw 207 to rotate slowly. Then, the nut seat 208 on the lead screw 207 moves closer to the lead screw 207, causing the sliding frame 216 to slide on the rod frame 209. At the same time, it also causes the L-shaped frame 210 to move, thereby moving the U-shaped frame 20 5. The piercing needle 211 moves along with the machine body 100, and its working end moves into the machine body 100 to pierce small waste paper boxes, milk cartons, and other waste, squeezing out the air inside and reducing their volume and density. As the L-shaped frame 210 moves, it contacts the sliding ring 213 located near the loop frame 205. The sliding ring 213 then moves the rod 214 and the central column 206. The central column 206 then moves the L-shaped push plate 203, dislodging the small waste paper boxes, milk cartons, and other waste accumulated inside the machine body 100 and above the top of the door panel 103. The compression is partially applied towards the back of the machine body 100. After compression, the compression stops, and then the working end of the drive motor 215 reverses. At this time, the lead screw 207 reverses, and the nut seat 208 moves towards the front of the machine body 100. This first moves the loop frame 205 and multiple needles 211. Then, the working ends of the needles 211 move to the inside of the L-shaped push plate 203. As the nut seat 208 continues to move, the L-shaped frame 210 contacts the sliding ring 213 near the L-shaped frame 210. This causes the sliding ring 213 near the L-shaped frame 210, the central column 206 of the rod 214, and the L-shaped push plate 203 pushed into the machine body 100 to move towards the front of the machine body 100 until the L-shaped push plate 203 moves to its original position.At this point, the hydraulic cylinder 101 can be activated to drive the lower pressure plate 102 downwards. The pressure plate 102 then compresses the waste inside the machine body 100. After compression, the hydraulic cylinder 101 moves the pressure plate 102 upwards to its original position. Then, following the reverse principle of closing the door panel 103 and the upper plate 200, open the upper plate 200 and door panel 103. Finally, activate the hydraulic rod 105 to drive the rear push plate 104 towards the front of the machine body 100, pushing the compressed, blocky waste outwards, completing the waste compression process.

[0046] When the nut seat 208 reciprocates on the lead screw 207, it also drives the blower 303, ring pipe 300, ring brush 301 and pipeline 302 to move. At the same time, the blower 303 is turned on, and the blower 303 generates air force that blows into the ring pipe 300 through the pipeline 302. Then, high-pressure air is blown out from multiple sets of blow holes on the inner wall of the ring pipe 300 to the outer wall of the lead screw 207, blowing away some dust and foreign objects attached to the outer surface of the lead screw 207. At the same time, the ring brush 301 can also sweep away some dust and foreign objects attached to the outer surface of the lead screw 207, preventing external dust and foreign objects from adhering to the outer wall of the lead screw 207 and causing wear between the lead screw 207 and the nut seat 208.

[0047] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
