Description

Technical Field

[0001] This invention relates to the field of environmental solid waste treatment technology, specifically to an energy-saving and environmentally friendly solid waste treatment device. Background Technology

[0002] The acceleration of industrialization and urbanization has led to an exponential increase in the amount of solid waste generated globally. Currently, conventional methods for treating solid waste mainly include landfill, incineration, simple crushing and sorting, and composting. However, these methods all have obvious technical defects and application limitations, making it difficult to meet the high standards of energy conservation, environmental protection, and resource recycling. Among them, traditional landfill methods occupy a large area, have limited site selection, and are prone to generating large amounts of leachate and landfill gas. High concentrations of pollutants in leachate can pollute groundwater and soil, while methane in landfill gas can exacerbate the greenhouse effect. At the same time, the landfill process wastes usable resources in solid waste.

[0003] Patent publication number CN210332805U includes a main body of a crushing device. The main body has a feed inlet at its top, and a movable plate below the feed inlet. The movable plate is located on top of a second support plate and a first support plate. One side of the movable plate is connected to a cylinder. A first guide plate is located below the movable plate and is inclined at the top of a first processing chamber. The main body of the crushing device contains a first processing chamber and a second processing chamber, with the first processing chamber located to the right of the second processing chamber. This environmentally friendly industrial solid waste crushing device separates the moisture contained in the industrial solid waste before crushing it, ensuring that the industrial solid waste is in a dry state during crushing. This avoids the accumulation of wastewater inside the crushing device and corrosion of the crushing gears, thereby ensuring the service life of the crushing device.

[0004] The aforementioned technology can separate moisture from industrial solid waste, ensuring that the solid waste is crushed in a dry state. This avoids the accumulation of sewage inside the crushing device and prevents corrosion of the crushing gears, effectively guaranteeing the service life of the crushing device. However, during the crushing of solid waste, the sewage separated from the waste and the moist components carried by the waste itself are prone to the growth of various bacteria. During the bacterial reproduction process, the organic components in the waste will decompose, thereby producing a large amount of foul-smelling gas, which can easily have an impact on the environment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an energy-saving and environmentally friendly solid waste treatment device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving and environmentally friendly solid waste treatment device, comprising a housing, a bracket mounted on the housing, and a servo motor mounted on the housing; the energy-saving and environmentally friendly solid waste treatment device further includes: A crushing mechanism, installed on the housing, is used to crush and pulverize solid waste for reuse. An extrusion mechanism, mounted on the housing, is used to extrude solid waste to improve the destructive effect of the solid waste; A spraying mechanism, installed on the housing, is used to suppress dust during the crushing process and remove bacteria from the waste.

[0007] The crushing mechanism includes a crushing roller installed on the output end of the servo motor and a toothed disc installed on the central shaft of the crushing roller. When solid waste needs to be processed, the solid waste falling on the surface of the crushing roller can be crushed, thereby crushing large and irregular waste into uniform fine particles, significantly reducing the volume of solid waste, achieving preliminary volume reduction, and improving the utilization rate of subsequent processing space. The extrusion mechanism includes an inclined frame mounted on the outer shell, a sliding rod mounted on the inclined frame, an eccentric wheel mounted on the crushing roller, a reset rod mounted on the inclined frame, a convex rod mounted on the reset rod, a moving rod mounted on the sliding rod, a pressing rod mounted on the moving rod, a bending rod mounted on the inclined frame, and a pressure plate mounted on the bending rod. During operation, the pressure plate comes into contact with the solid waste. In the process of crushing the waste, it effectively increases the contact area between the waste and the crushing roller, thereby significantly improving the crushing effect and overall treatment efficiency. It also increases crushing efficiency, shortens processing time, reduces drive energy consumption, and achieves energy-saving and environmentally friendly operation. Furthermore, it avoids problems such as slippage, missed cutting, and incomplete local crushing. The spraying mechanism includes a reagent tank mounted on the outer casing, a chamfered block mounted on the outer casing, a second pressing rod mounted on the pressure plate, a rotating rod mounted on the chamfered block, a spraying plate mounted on the rotating rod, and a force-bearing rod mounted on the rotating rod. The spraying plate is connected to the reagent tank via a hose. During the crushing of the fertilizer, the rotation of the bending rod drives the second pressing rod to rotate, activating the water pump inside the reagent tank and delivering the deodorizing and antibacterial agent to the spraying plate through a pipeline. Subsequently, the deodorizing and antibacterial agent is sprayed out through the spraying plate onto the surface of the solid waste, thereby inhibiting the spread of odors and bacterial growth at the source, significantly improving the environmental protection effect of the device, preventing odor leakage and pollution of the surrounding environment, and ensuring that the agent adheres evenly to the surface of the waste particles during the crushing process, achieving all-round coverage treatment, slowing down the decomposition and deterioration of organic waste, reducing the generation of leachate and harmful gases, and thus rendering the waste harmless to the surrounding environment.

[0008] The crushing rod is rotatably connected to the outer shell. The surface of the reset rod is provided with a spring. The spring is used to pull the convex rod to reset. The convex rod is slidably connected to the reset rod. The convex rod is in contact with the eccentric wheel. The pressing rod is in contact with the bending rod.

[0009] The extrusion mechanism also includes a screening mechanism mounted on the sliding rod. The screening mechanism includes a pull rod mounted on the convex rod, a screening plate mounted on the outer shell, an elastic telescopic rod mounted on the outer shell, and a support plate mounted on the elastic telescopic rod. The support plate supports the screening plate and assists in its resetting. When crushing fertilizer, it supports the screening plate to prevent damage during its up-and-down reciprocating movement. Simultaneously, the shaking of the screening plate causes the waste accumulated on the surface to shake synchronously. Smaller waste pieces fall through the screening plate, while larger pieces that are not completely crushed are shaken out when the screening plate rotates downwards. This allows for the separation and screening of qualified and poorly crushed waste, significantly improving the continuity, energy efficiency, environmental protection, and resource utilization rate of solid waste treatment. Furthermore, incompletely crushed waste can be returned to the crushing mechanism for secondary crushing, avoiding equipment blockage or incomplete processing due to uneven material size.

[0010] The screening mechanism also includes an elastic rod mounted on the pressure plate and an arc-shaped pressure plate mounted on the elastic rod. The surface of the elastic rod is provided with a spring, and the arc-shaped pressure plate is used to further compress the solid waste. The screening mechanism is used to separate larger pieces of waste material that have not been completely crushed.

[0011] The support plate and the screen plate are in contact with each other. During operation, the pull rod will drive the screen plate to move synchronously. During the extrusion of waste, the support rod can continue to apply force to the waste even when it is bending away from the waste. This provides a moderate and stable clamping force to the waste during the crushing process, making the loose material tightly adhere to the crushing roller, significantly increasing the contact area between the two, improving the uniformity of crushing and processing efficiency. At the same time, the elastic pressure provided by the spring can automatically adjust the degree of clamping according to the thickness and hardness of the waste. This ensures effective compaction of waste of different hardness, avoids jamming, overload and equipment damage caused by rigid extrusion, improves operational reliability, and prevents the waste from bouncing and slipping under the action of elastic extrusion. It also makes the crushing more thorough and the particles more uniform, laying a good foundation for subsequent pyrolysis, conversion and resource utilization.

[0012] The screening mechanism also includes a pushing mechanism mounted on the bending rod. The pushing mechanism includes a pushing plate mounted on the outer shell, a connecting rod mounted on the pressing rod, and a connecting rod mounted on the connecting rod. The pushing plate is used to push the fertilizer remaining on the outer shell to move. During the crushing process, it can effectively ensure the continuous and stable feeding of solid waste, improve the overall treatment efficiency and operational reliability, and prevent waste from accumulating at the inlet. At the same time, uniform pushing can make the waste enter the working area at a stable rate, making the crushing, extrusion, and chemical spraying processes more uniform and sufficient, preventing poor crushing effect and incomplete extrusion due to inconsistent feeding speed. Stable and continuous feeding can also reduce the idle energy consumption of the equipment and reduce the losses caused by frequent start-stop of the servo motor, further achieving energy-saving operation. The pushing mechanism is used to improve the feeding effect of solid waste.

[0013] The pushing mechanism also includes a perforated block mounted on the screen plate, a pressing plate mounted on the perforated block, a transmission wheel mounted on the pressing plate, and a protrusion mounted on the outer casing. The outer casing is equipped with a protective plate for protecting the elastic telescopic rod. During the discharge process, the transmission wheel will contact the outer casing and knock on it, which can effectively prevent the processed waste from sticking, accumulating, or blocking at the discharge position, ensuring smooth discharge and continuous and stable operation of the device. The vibration generated by the intermittent knocking can cause the adhered material to fall off and the loosely accumulated material to fall smoothly, avoiding the accumulation of internal material due to poor discharge, which would affect the normal operation of the front-end processes such as crushing and extrusion.

[0014] The outer casing is in contact with the transmission wheel, and the push plate is rotatably connected to the connecting rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when solid waste needs to be processed, the solid waste falling onto the surface of the crushing roller can be crushed, thereby breaking large, irregular pieces of waste into uniform, fine particles, significantly reducing the volume of solid waste, achieving initial volume reduction, and improving the utilization rate of subsequent processing space. During the crushing process, the contact area between the waste and the crushing roller can be effectively increased, thus significantly improving the crushing effect and overall treatment efficiency. It can also improve crushing efficiency, shorten processing time, and reduce drive energy consumption, achieving energy-saving and environmentally friendly operation. Furthermore, it can avoid problems such as slippage, missed cutting, and incomplete local crushing. During the crushing process of the fertilizer, the rotation of the bending rod will drive the second pressing rod to rotate. The water pump inside the agent tank will start and deliver the deodorizing and antibacterial agent to the spray plate through the pipeline. Then, the deodorizing and antibacterial agent will be sprayed out through the spray plate and sprayed onto the surface of the solid waste. This can inhibit the spread of odor and the growth of bacteria from the source, significantly improve the environmental protection effect of the device, and prevent odor leakage from polluting the surrounding environment. At the same time, the agent is evenly attached to the surface of the waste particles during the crushing process, which can achieve all-round coverage treatment, slow down the decomposition and deterioration of organic waste, reduce the generation of leachate and harmful gases, and thus make the waste harmless to the surrounding environment.

[0016] 2. In this invention, when crushing fertilizer, the screen plate can be supported to prevent damage during its reciprocating movement. Simultaneously, the shaking of the screen plate will cause the waste accumulated on the surface to shake synchronously. At this time, smaller waste will fall through the screen plate, while larger pieces of waste that are not completely crushed will be shaken out when the screen plate rotates downward. This allows for the separation and screening of waste that is properly crushed from waste that is poorly crushed. This can significantly improve the continuity, energy conservation, environmental protection, and resource utilization rate of solid waste treatment. At the same time, waste that is not thoroughly crushed can be returned to the crushing mechanism for secondary crushing, avoiding equipment blockage or incomplete treatment caused by uneven material size.

[0017] 3. In this invention, during the extrusion of waste materials, force can be continuously applied to the waste materials even when the bending rod leaves the waste materials. This provides a moderate and stable clamping force to the waste materials during the crushing process, making the loose materials tightly adhere to the crushing rollers, significantly increasing the contact area between the two, improving the uniformity of crushing and processing efficiency. At the same time, the elastic pressure provided by the spring can automatically adjust the degree of clamping according to the thickness and hardness of the waste materials. This ensures effective compaction of waste materials of different hardnesses, while avoiding material jamming, overload, and equipment damage caused by rigid extrusion, thus improving operational reliability. Under the action of elastic extrusion, the waste materials are less likely to bounce or slip, and the crushing is more thorough, resulting in more uniform particles, laying a good foundation for subsequent pyrolysis, conversion, and resource utilization.

[0018] 4. In this invention, during the crushing process, the continuous and stable feeding of solid waste can be effectively ensured, improving the overall treatment efficiency and operational reliability, preventing waste from accumulating at the inlet. At the same time, the uniform feeding allows the waste to enter the working area at a stable rate, making the crushing, extrusion, and chemical spraying processes more uniform and thorough, preventing poor crushing effect and incomplete extrusion due to inconsistent feeding speed. The stable and continuous feeding also reduces the idle energy consumption of the equipment and reduces the losses caused by frequent start-stop of the servo motor, further achieving energy-saving operation. During the discharge process, the transmission wheel will contact the outer shell and knock on the outer shell, which can effectively prevent the treated waste from sticking, accumulating, or blocking at the discharge position, ensuring smooth discharge and continuous and stable operation of the device. The vibration generated by the intermittent knocking can cause the adhered material to fall off and the loosely accumulated material to fall smoothly, avoiding the accumulation of internal material due to poor discharge, which would affect the normal operation of the front-end processes such as crushing and extrusion.

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

[0022] Example 1: Please see Figures 1-7 One embodiment of the present invention is: an energy-saving and environmentally friendly solid waste treatment device, comprising a housing 1, a bracket 2 mounted on the housing 1, and a servo motor 3 mounted on the housing 1. The energy-saving and environmentally friendly solid waste treatment device further includes: The crushing mechanism, installed on the outer casing 1, is used to crush and pulverize solid waste for reuse, thereby crushing large and irregular waste into uniform and fine particles, significantly reducing the volume of solid waste, achieving initial volume reduction, and improving the utilization rate of subsequent processing space. The extrusion mechanism, installed on the housing 1, is used to extrude solid waste to improve the crushing effect of solid waste, thereby effectively increasing the contact area between the waste and the crushing roller 4, and thus significantly improving the crushing effect and overall treatment efficiency. The spraying mechanism, installed on the outer casing 1, is used to suppress dust during the crushing process and remove bacteria from the waste, thereby suppressing the spread of odors and the growth of bacteria, significantly improving the environmental protection effect of the device, preventing odor leakage from polluting the surrounding environment, and rendering the waste harmless. The crushing mechanism includes a crushing roller 4 mounted on the output end of the servo motor 3 and a toothed disc 5 mounted on the central shaft of the crushing roller 4; The extrusion mechanism includes an inclined frame 7 mounted on the outer shell 1, a sliding rod 8 mounted on the inclined frame 7, an eccentric wheel 9 mounted on the crushing roller 4. During the rotation of the eccentric wheel 9, it will contact the convex rod 11 and push the convex rod 11 downward through the extrusion force. The mechanism also includes a reset rod 10 mounted on the inclined frame 7, a convex rod 11 mounted on the reset rod 10, a moving rod 12 mounted on the sliding rod 8, a pressing rod 13 mounted on the moving rod 12, a bending rod 14 mounted on the inclined frame 7, and a pressure plate 15 mounted on the bending rod 14. During operation, the pressure plate 15 will contact the solid waste. During the rotation of the pressure plate 15, it will contact the solid waste and generate a downward extrusion force on the waste. The spraying mechanism includes a reagent tank 6 mounted on the outer casing 1, a chamfered block 16 mounted on the outer casing 1, a pressing rod 17 mounted on the pressing plate 15, a rotating rod 18 mounted on the chamfered block 16, a spraying plate 19 mounted on the rotating rod 18, and a force-bearing rod 22 mounted on the rotating rod 18. The spraying plate 19 is connected to the reagent tank 6 via a hose.

[0023] In this embodiment, when solid waste needs to be processed, the solid waste is fed into the interior of the outer shell 1 through the inlet, causing the waste to fall onto the surface of the crushing roller 4. After the waste is fed in, the servo motor 3 starts and drives the crushing roller 4 to rotate. The rotation of the crushing roller 4 drives the toothed disc 5 to rotate, and the rotation of the toothed disc 5 drives the right toothed disc 5 to rotate in the opposite direction through its teeth. The rotation of the right toothed disc 5 drives the right crushing roller 4 to rotate synchronously, thereby crushing the solid waste falling onto the surface of the crushing roller 4. This crushes large, irregular pieces of waste into uniform, fine particles, significantly reducing the volume of solid waste, achieving initial volume reduction, and improving the utilization rate of subsequent processing space. During the crushing process, the rotation of the crushing roller 4 drives the eccentric wheel 9 to rotate. During the rotation of the eccentric wheel 9, it contacts the convex rod 11 and pushes the convex rod 11 downward through the squeezing force. The downward movement of the convex rod 11 pulls... When the spring on the surface of the resetting rod 10 does not contact the convex rod 11 at the protrusion of the eccentric wheel 9, the spring on the surface of the resetting rod 10 will contract and drive the convex rod 11 to move upward. The up and down movement of the convex rod 11 will synchronously drive the moving rod 12 to move. The downward movement of the moving rod 12 will drive the pressing rod 13 to move downward. The downward movement of the pressing rod 13 will generate a squeezing force on the bending rod 14, forcing the bending rod 14 to rotate downward. The rotation of the bending rod 14 will drive the pressure plate 15 to rotate synchronously. During the rotation of the pressure plate 15, it will come into contact with the solid waste and generate a downward squeezing force on the waste, thereby effectively increasing the contact area between the waste and the crushing roller 4, thus significantly improving the crushing effect and overall treatment efficiency, improving the crushing efficiency, shortening the processing time, reducing drive energy consumption, achieving energy-saving and environmentally friendly operation, and avoiding problems such as slippage, missed cutting, and incomplete crushing in some areas.

[0024] The crushing rod 4 is rotatably connected to the outer shell 1. The surface of the reset rod 10 is provided with a spring, which is used to pull the convex rod 11 to reset. The convex rod 11 is slidably connected to the reset rod 10. The convex rod 11 is in contact with the eccentric wheel 9. The first pressing rod 13 is in contact with the bending rod 14. The rotation of the bending rod 14 will drive the second pressing rod 17 to rotate.

[0025] During the crushing process of fertilizer, the rotation of the bending rod 14 drives the second pressing rod 17 to rotate. During the rotation of the second pressing rod 17, it comes into contact with the force rod 22 and pushes the force rod 22 to rotate through the squeezing force. The rotation of the force rod 22 drives the rotating rod 18 to rotate, and the rotation of the rotating rod 18 drives the spraying plate 19 to rotate synchronously. At the same time, during the rotation of the spraying plate 19, the water pump inside the agent tank 6 starts and delivers the deodorizing and antibacterial agent to the inside of the spraying plate 19 through the pipeline. Then, the deodorizing and antibacterial agent is sprayed out through the spraying plate 19 and sprayed onto the surface of the solid waste, thereby inhibiting the diffusion of odor and the growth of bacteria, significantly improving the environmental protection effect of the device, preventing odor leakage and pollution of the surrounding environment. At the same time, the agent is evenly attached to the surface of the waste particles during the crushing process, which can achieve all-round coverage treatment, slow down the decomposition and deterioration of organic waste, reduce the generation of leachate and harmful gases, and thus make the waste harmless to the surrounding environment.

[0026] Example 2: Please see Figures 5-7 Based on the above embodiments, in another embodiment of the present invention, the extrusion mechanism further includes a screening mechanism 20 mounted on the sliding rod 8. The screening mechanism 20 includes a pull rod 201 mounted on the convex rod 11, a screening plate 202 mounted on the outer shell 1, an elastic telescopic rod 203 mounted on the outer shell 1, and a support plate 204 mounted on the elastic telescopic rod 203. The downward movement of the support plate 204 will cause the elastic telescopic rod 203 to be compressed. The support plate 204 is used to support the screening plate 202 and assist it in resetting.

[0027] In this embodiment, during fertilizer crushing, the crushed fertilizer falls onto the surface of the screen plate 202. Simultaneously, the convex rod 11 moves up and down, contacting the screen plate 202 and causing it to rotate. As the screen plate 202 rotates downwards, it contacts the support plate 204, exerting a downward compressive force on it, forcing the support plate 204 to move downwards. This downward movement of the support plate 204 compresses the elastic telescopic rod 203. When the convex rod 11 moves upwards, the pulling rod 201 simultaneously rotates the screen plate 202 upwards. At this time, the elastic telescopic rod 203 moves upwards to reset and also moves the support plate 204 upwards. The screen plate 202 is moved to support it, preventing damage during its reciprocating movement. Simultaneously, the shaking of the screen plate 202 causes the waste material accumulated on its surface to shake synchronously. Smaller pieces of waste fall through the screen plate 202, while larger pieces that are not fully crushed are shaken out as the screen plate 202 rotates downwards. This allows for the separation of properly crushed and poorly crushed waste, significantly improving the continuity, energy efficiency, environmental friendliness, and resource utilization rate of solid waste treatment. Furthermore, incompletely crushed waste can be returned to the crushing mechanism for secondary crushing, avoiding equipment blockage or incomplete processing caused by uneven material size.

[0028] The screening mechanism 20 also includes an elastic rod 205 mounted on the pressure plate 15 and an arc-shaped pressure plate 206 mounted on the elastic rod 205. The movement of the elastic rod 205 will compress the spring provided on the surface of the arc-shaped pressure plate 206. The surface of the elastic rod 205 is provided with a spring, and the arc-shaped pressure plate 206 is used to further compress the solid waste. The screening mechanism 20 is used to separate larger pieces of waste material that have not been crushed. The support plate 204 and the screen plate 202 are in contact with each other. During operation, the pull rod 201 will drive the screen plate 202 to move synchronously. During the downward rotation of the screen plate 202, it will come into contact with the support plate 204.

[0029] During the extrusion of waste material, the rotation of the pressure plate 15 drives the elastic rod 205 to rotate synchronously. The rotation of the elastic rod 205 drives the arc-shaped pressure plate 206 to rotate. During the rotation of the arc-shaped pressure plate 206, it exerts extrusion force on the waste material. At this time, the elastic rod 205 continues to move, and the movement of the elastic rod 205 compresses the spring on the surface of the arc-shaped pressure plate 206. When the bending rod 14 moves in the opposite direction, the spring on the surface of the elastic rod 205 will reset and extrude extrusion force on the arc-shaped pressure plate 206, pushing the arc-shaped pressure plate 206 to move. Thus, even when the bending rod 14 leaves the waste material, it can still continuously apply force to the waste material. This allows for a continuous and stable clamping force on the waste material during the crushing process, ensuring that the loose material adheres tightly to the crushing roller, significantly increasing the contact area between the two, improving crushing uniformity and processing efficiency. At the same time, the elastic pressure provided by the spring can automatically adjust the clamping degree according to the thickness and hardness of the waste material, ensuring effective compaction of waste materials of different hardness, while avoiding material jamming, overload, and equipment damage caused by rigid extrusion, thus improving operational reliability. Under the action of elastic extrusion, the waste material is less likely to bounce or slip, and the crushing is more thorough, resulting in more uniform particles, laying a good foundation for subsequent pyrolysis, conversion, and resource utilization.

[0030] Example 3: Please see Figures 7-8 Based on the above embodiments, in another embodiment of the present invention, the screening mechanism 20 further includes a pushing mechanism 21 mounted on the bending rod 14. The pushing mechanism 21 includes a pushing plate 211 mounted on the outer shell 1, a connecting rod 212 mounted on the pressing rod 17, and a connecting rod 213 mounted on the connecting rod 212. The pushing plate 211 is used to push the fertilizer remaining on the outer shell 1 to move. The pushing mechanism 21 is used to improve the feeding effect of solid waste. The connecting rod 212 will drive the pushing plate 211 to move to the right.

[0031] In this embodiment, during the crushing process, when the pressure rod 17 rotates downward, it generates a compressive force on the connecting rod 212, forcing the connecting rod 212 to move to the left. The leftward movement of the connecting rod 212 generates a compressive force on the connecting rod 213, causing the connecting rod 213 to move under the compressive force. During the movement of the connecting rod 213, it drives the push plate 211 to move. Conversely, when the bending rod 14 rotates upward, the connecting rod 212 drives the push plate 211 to move to the right, thereby pushing the waste material remaining on the surface of the outer shell 1 to move. This effectively ensures continuous and stable feeding of solid waste, improves overall treatment efficiency and operational reliability, and prevents waste material from accumulating at the inlet. At the same time, uniform feeding allows the waste material to enter the working area at a stable rate, making the crushing, compressing, and chemical spraying processes more uniform and thorough. This prevents poor crushing effect and inadequate compressing caused by inconsistent feeding speed. Stable and continuous feeding also reduces the idle energy consumption of the equipment and reduces the losses caused by frequent start-stop of the servo motor 3, further achieving energy-saving operation.

[0032] The driving mechanism 21 also includes a perforated block 214 mounted on the screen plate 202, a pressing plate 215 mounted on the perforated block 214, a transmission wheel 217 mounted on the pressing plate 215, and a protrusion 216 mounted on the housing 1. A protective plate 218 for protecting the elastic telescopic rod 203 is installed on the housing 1.

[0033] The outer casing 1 is in contact with the transmission wheel 217. During the rotation of the transmission wheel 217, it will contact the protrusion 216 and exert a squeezing force on the transmission wheel 217, which will push the plate 211 and the connecting rod 213 to rotate and connect.

[0034] During the discharge process, when the screen plate 202 rotates downward, it drives the hollow block 214 to move downward. The downward movement of the hollow block 214 will exert a squeezing force on the pressure plate 215, forcing the pressure plate 215 to rotate. The rotation of the pressure plate 215 will drive the transmission wheel 217 to rotate. During the rotation, the transmission wheel 217 will contact the protrusion 216 and exert a squeezing force on the transmission wheel 217, forcing the transmission wheel 217 to move upward. After the transmission wheel 217 passes the protrusion 216, the transmission wheel 217 will contact the outer shell 1 and knock on the outer shell 1. This can effectively prevent the processed waste material from sticking, accumulating or blocking at the discharge position, ensuring smooth discharge and continuous and stable operation of the device. The vibration generated by intermittent knocking can cause the sticky material to fall off and the loosely accumulated material to fall smoothly, avoiding the accumulation of internal material due to poor discharge, which would affect the normal operation of the front-end processes such as crushing and extrusion.
