Description

Technical Field

[0001] This invention relates to the field of building decoration construction technology, and in particular to a dustproof crushing and recycling device and recycling process for building decoration waste. Background Technology

[0002] Construction and decoration waste, as an important component of construction waste, mainly comes from the interior decoration of new buildings, the secondary renovation of existing buildings, and demolition and decoration projects. Generally, construction and decoration waste includes tiles, waste bricks, cement mortar blocks, wood, etc. Among them, solid waste such as tiles and waste bricks are relatively common and have recycling value, for example, they can be used as floor fillers. Directly discarding them would result in a waste of resources.

[0003] Currently, the recycling and processing of solid waste such as tiles and bricks from construction and decoration waste is carried out using common and universal material crushers. The solid waste is mainly fed into the crusher manually, and then fully crushed by the crushing components inside the crusher, such as crushing rollers and crushing blades. During the crushing process, the equipment is covered with a dust cover to prevent dust generated during crushing from spreading and causing pollution. The crushed waste is then bagged and recycled for subsequent use.

[0004] However, most current material crushers have funnel-shaped fixed guide channels for their feed inlets. Some construction and decoration solid waste may be excessively long, such as rectangular tiles. In such cases, it is impossible to directly feed the waste into the crusher through the inlet. The waste must be manually broken into pieces and then fed into the crusher. Although it is possible to insert the waste vertically into the inlet, the bottom of the waste will contact the crushing components first, causing the top of the waste to become unbalanced and tilt, easily falling out from the edge of the inlet. In the end, manual collection and processing are still required. At the same time, during the process of feeding construction and decoration waste into the crushing equipment, dust is generated when the waste is crushed at the moment of feeding. The dust spreads directly outward from the inlet, causing pollution. Summary of the Invention

[0005] The purpose of this invention is to provide a dustproof crushing and recycling device and recycling process for construction and decoration waste, so as to solve the technical problem in the prior art that it is inconvenient to put long solid waste within a certain range into the crusher for processing.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution: A dustproof crushing and recycling device for construction and decoration waste includes a dustproof casing and a crusher. A feed inlet is provided on one side of the dustproof casing, and the crusher is located at the bottom of the dustproof casing. A recycling inlet for discharging the crushed waste is provided on one side of the bottom of the crusher. The device also includes: An auxiliary feeding mechanism includes a tilting pallet and an auxiliary clamping mechanism. The tilting pallet is rotatably disposed on one side of the bottom of the feed inlet. The tilting pallet tilts and drives the waste material into the feed inlet. The auxiliary clamping mechanism includes two sets of crushing clamps symmetrically distributed on the tilting pallet. The two sets of crushing clamps slide from both sides to the middle and crush the waste material during the tilting process of the tilting pallet. A dust extraction mechanism is used to extract dust during the feeding process of the flipped pallet to the feed inlet.

[0007] Preferably, the auxiliary feeding mechanism further includes a hydraulic telescopic rod and a linkage mechanism. The hydraulic telescopic rod is vertically fixed to one side of the outer wall of the dustproof housing. The telescopic end of the hydraulic telescopic rod drives the flipping tray to flip through the linkage mechanism.

[0008] Preferably, the linkage mechanism is provided in two sets and symmetrically distributed on both sides of the flipping tray. Each set of the linkage mechanism includes a connecting guide rail and a connecting slider. The connecting guide rail is fixedly connected to the edge of the flipping tray in parallel. The connecting slider is slidably connected to the connecting guide rail. The telescopic end of the hydraulic telescopic rod is fixedly connected to a lifting frame. The end of the lifting frame is rotatably connected to the connecting slider through a rotating shaft.

[0009] Preferably, each set of linkage mechanisms further includes a first rack, a transmission gear, and a second rack; the first rack is fixedly connected to the corresponding connecting slider, and the first rack is distributed parallel to the connecting guide rail; the transmission gear is rotatably disposed on one side of the flipping pallet, and the second rack is fixedly connected to the corresponding crushing clamp; the second rack is perpendicular to the first rack, and both the second rack and the first rack mesh with the transmission gear.

[0010] Preferably, a plurality of slitting blades are fixedly connected at equal intervals on the inner side of the feed inlet, and a plurality of through cuts that are aligned and cooperate with the slitting blades are opened at equal intervals on the flip plate.

[0011] Preferably, the device also includes an inclined guide plate, which is inclinedly positioned below the tilting tray and fixedly connected to the crusher. An auxiliary inlet is provided on the top of the crusher near the inclined guide plate. The inclined guide plate is used to catch the crushed material leaking from the through cut and guide the crushed material into the crusher through the auxiliary inlet.

[0012] Preferably, the device further includes a dust collection mechanism, which includes a negative pressure dust collection device, a main dust collection pipe, a secondary dust collection pipe, and an adjustable external dust collection component. The main dust collection pipe is connected to the negative pressure end of the negative pressure dust collection device and is positioned above the crusher. Two sets of adjustable external dust collection components are provided and symmetrically distributed on both sides of the tilting tray. The adjustable external dust collection components are connected to the main dust collection pipe through the secondary dust collection pipe.

[0013] Preferably, the adjustable external vacuum assembly includes a square box and a sealing plug. The square box is fixedly connected to the dustproof housing and is vertically distributed on the side of the flip-up tray. The auxiliary vacuum pipe is fixedly connected to the top of the square box, and the diameter of the auxiliary vacuum pipe is smaller than the cross-sectional width of the square box. Multiple negative pressure nozzles are longitudinally and equidistantly distributed on the side of the square box near the flip-up tray. The sealing plug is fitted inside the square box and is used to seal the auxiliary vacuum pipe. The sealing plug rises and falls synchronously with the telescopic end of the hydraulic telescopic rod.

[0014] Preferably, a crushing roller is installed at the top of the crusher; a rotating crushing blade is provided on one side of the bottom of the crusher.

[0015] A dust-proof crushing and recycling process for construction and decoration waste includes the following steps: Step 1: Place the construction and decoration waste onto the tilting pallet and control the tilting pallet to tilt; The second step involves the flipping of the pallet. During the flipping process, the two sets of crushing clamps clamp each other from both sides toward the middle, thus pre-crushing the waste material passing through the feed inlet. The third step is that the pre-crushed waste enters the dustproof casing through the feed inlet and falls into the crusher for crushing. Step 4: Place the dustproof bag on the recycling port and discharge the crushed waste into the dustproof bag through the recycling port.

[0016] The beneficial effects of this invention are: 1. In this invention, when the waste material is fed into the side-mounted feed inlet by the flipping action of the flipping pallet, the pair of crushing clamps distributed on both sides of the flipping pallet automatically clamp towards the middle, which facilitates the crushing and centering of waste material that is too long within a certain size range, so that the waste material can fully and effectively enter the device from the feed inlet for crushing and recycling.

[0017] 2. The present invention uses the extension end of the hydraulic telescopic rod to pull the rotating connecting slider, causing the connecting slider to slide along the connecting guide rail on the flipping pallet, thereby realizing the flipping pallet flipping. In addition, during the sliding process of the connecting slider relative to the connecting guide rail, the first rack, the second rack and the transmission gear cooperate to drive the crushing clamps distributed on both sides of the flipping pallet to automatically clamp and stably complete the feeding pre-treatment crushing process.

[0018] 3. This invention uses a negative pressure dust collection device to generate negative pressure in both the main and auxiliary dust collection pipes. The main dust collection pipe can directly collect dust from the inside of the crushing device, while the auxiliary dust collection pipe, in conjunction with the square box and the negative pressure nozzle, collects dust around the tilting pallet during the feeding process. This prevents dust generated during the pre-crushing of waste materials by the tilting pallet from being released into the surrounding environment and causing pollution.

[0019] 4. During the process of driving the tilting pallet to tilt and feed material, the hydraulic telescopic rod of the present invention simultaneously drives the sealing plug set in the square bar box to move. When the tilting pallet completes feeding and blocks the feed inlet, the sealing plug just blocks the port of the auxiliary dust suction pipe, so that the negative pressure is concentrated through the main dust suction pipe to act on the dust generated in the crushing process of the crusher, avoiding the need to continue to rely on the auxiliary dust suction pipe to do useless work under negative pressure outside the device.

Detailed Implementation

[0022] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] like Figures 1 to 9 As shown, a dustproof crushing and recycling device for construction and decoration waste is mainly used to crush solid construction and decoration waste such as ceramic tiles and concrete blocks to obtain crushed stone materials for recycling. The device includes a dustproof housing 1 and a crusher 3. A feed inlet 11 for feeding construction and decoration waste is provided on one side of the dustproof housing 1. The crusher 3 is located at the bottom of the dustproof housing 1. When the waste is fed in through the feed inlet 11, it falls into the crusher 3 and is crushed by the crusher 3. The dustproof housing 1 is used to reduce the amount of dust that spreads outward during the crushing process. A recycling port 31 for discharging the crushed waste is provided on one side of the bottom of the crusher 3. It should also be noted that the bottom of the entire device is evenly distributed with casters with self-locking function, which facilitates the free movement of the entire device to the corresponding area for waste recycling.

[0024] The recycling device also includes an auxiliary feeding mechanism 2 and a dust collection mechanism 4. The auxiliary feeding mechanism 2 includes a flipping pallet 21 and an auxiliary clamping mechanism. The flipping pallet 21 is rotatably set on one side of the bottom of the feed inlet 11. The flipping pallet 21 flips and drives the waste into the feed inlet 11. The auxiliary clamping mechanism includes two sets of crushing clamps 23 symmetrically distributed on the flipping pallet 21. The two sets of crushing clamps 23 slide from both sides to the middle to crush the waste during the flipping process of the flipping pallet 21, so as to avoid the waste being too long and not easy to effectively enter the feed inlet 11. At the same time, it is initially crushed during the feeding process, which is convenient for subsequent crushing processing.

[0025] It should be noted that when the tilting pallet 21 is disengaged from the feed inlet 11 and in the open state, the tilting pallet 21 can be in a horizontal position. At this time, the crushing clamp 23 stays at the edge of the tilting pallet 21. The length of the tilting pallet 21 is greater than the size of the feed inlet 11. Therefore, the distance between the two sets of crushing clamps 23 is greater than the lateral length of the feed inlet 11. In order to prevent the crushing clamp 23 from directly contacting the outer wall of the dustproof housing 1 and causing motion interference during the tilting pallet 21's tilting and approaching the feed inlet 11, the crushing clamp 23 can be kept at a certain distance from the outer wall of the dustproof housing 1 when it is in a horizontal position.

[0026] The dust collection mechanism 4 is used to collect dust during the feeding process from the flipping pallet 21 to the feed inlet 11.

[0027] A dust-proof crushing and recycling process for construction and decoration waste includes the following steps: Step 1: Place the construction and decoration waste on the tilting pallet 21 and control the tilting pallet 21 to tilt. The second step is that during the flipping process of the flipping pallet 21, the two sets of crushing clamps 23 clamp each other from both sides to the middle, so that the waste material passing through the feed inlet 11 is pre-crushed. The third step is that the pre-crushed waste enters the dustproof housing 1 through the feed inlet 11 and falls into the crusher 3 for crushing. Step 4: Place the dustproof bag into the recycling port 31, and discharge the crushed waste into the dustproof bag through the recycling port 31.

[0028] In some specific implementation plans, combined with Figure 1 and Figure 4 As shown, the auxiliary feeding mechanism 2 also includes a hydraulic telescopic rod 24 and a linkage mechanism 26. The hydraulic telescopic rod 24 is vertically fixed to one side of the outer wall of the dustproof housing 1 and is on the same side as the feed inlet 11. The telescopic end of the hydraulic telescopic rod 24 faces downward. The telescopic end of the hydraulic telescopic rod 24 drives the flipping tray 21 to flip through the linkage mechanism 26. For example, when the hydraulic telescopic rod 24 retracts, the flipping tray 21 rotates and fits onto the feed inlet 11. When the hydraulic telescopic rod 24 extends, the flipping tray 21 rotates and disengages from the feed inlet 11.

[0029] In a further specific implementation, two sets of linkage mechanisms 26 are provided and symmetrically distributed on both sides of the tilting pallet 21. Each set of linkage mechanisms 26 includes a connecting guide rail 261 and a connecting slider 262. The connecting guide rail 261 is fixedly connected to the edge of the tilting pallet 21 in parallel, and the connecting guide rail 261 can be located on the side of the tilting pallet 21 away from the feed inlet 11. The connecting slider 262 is slidably connected to the connecting guide rail 261. The connecting slider 262 can be I-shaped and is limited to the connecting guide rail 261, preventing it from falling off. The telescopic end of the hydraulic telescopic rod 24 is fixedly connected to a lifting frame 25. Both ends of the lifting frame 25 are bent downward and extend vertically to the corresponding positions of the connecting slider 262, and are rotatably connected to the connecting slider 262 through a rotating shaft. It should also be noted that the tilting pallet 21 and the feed inlet 11 are connected to the connecting guide rail 262 in parallel. The bottom edge of the feed inlet 11 can be rotated to the midpoint of the end of the connecting guide rail 261. When the hydraulic telescopic rod 24 is extended, the tilting pallet 21 is in a horizontal position, and the connecting slider 262 is at the end of the connecting guide rail 261 near the feed inlet 11. When it is necessary to feed solid construction waste into the device for crushing and recycling, the waste is placed on the tilting pallet 21, and then the hydraulic telescopic rod 24 is retracted. The extension end of the hydraulic telescopic rod 24 pulls the rotating connecting slider 262 through the lifting frame 25. The connecting slider 262 then drives the tilting pallet 21 to tilt towards the feed inlet 11. During this process, the connecting slider 262 rotates relative to the lifting frame 25 and slides along the connecting guide rail 261 away from the rotation axis of the tilting pallet 21. For details, please refer to [reference needed]. Figure 7 As shown, this gradually rotates the flipping tray 21 from a horizontal position to a vertical position that fits the feed inlet 11, making it easier for waste material to enter the feed inlet 11.

[0030] In some specific implementation schemes, refer to Figures 4 to 6 As shown, each linkage mechanism 26 also includes a first rack 263, a transmission gear 264, and a second rack 265. The first rack 263 is fixedly connected to the corresponding connecting slider 262, and the first rack 263 is distributed parallel to the connecting guide rail 261. The transmission gear 264 is rotatably mounted on one side of the flipping tray 21 via a shaft bracket, and maintains a certain distance from the edge of the flipping tray 21. The second rack 265 is fixedly connected to the corresponding crushing clamp 23, and the second rack 265 is parallel to the flipping tray 21. The second rack 265 is perpendicular to the first rack 263, and both the second rack 265 and the first rack 263 mesh with the transmission gear 264. The transmission gear 264 can be in the shape of a toothed column, which facilitates the first rack 263 and the second rack 265 to be staggered and avoid mutual interference.

[0031] When the hydraulic telescopic rod 24 drives the tilting pallet 21 to tilt and feed material into the feed inlet 11 via the connecting guide rail 261 and the connecting slider 262, the connecting slider 262 slides along the connecting guide rail 261. This causes the connecting slider 262 to drive the first rack 263 to move synchronously. The first rack 263 then drives the transmission gear 264 to rotate, which in turn drives the second rack 265 to move. The second rack 265 then drives the corresponding crushing clamp 23 to move towards the center of the tilting pallet 21. Thus, the crushing clamps 23 on both sides of the tilting pallet 21 can move towards the center. The clamping mechanism facilitates the crushing of excessively long waste materials. When the crushing clamp 23 moves with the tilting pallet 21 to the vertical plane where the feed inlet 11 is accessible, the crushing clamp 23, which moves from both sides of the tilting pallet 21 towards the middle, enters the opening range of the feed inlet 11. At this time, the crushing clamp 23 cuts into the feed inlet 11, avoiding collision with the side wall of the dustproof housing 1. Finally, when the tilting pallet 21 closes and seals the feed inlet 11, the crushing clamp 23 is also completely cut into the feed inlet 11. This allows even excessively long waste materials to be effectively fed into the feed inlet 11, while also achieving initial crushing.

[0032] In some specific implementation schemes, in order to further facilitate the effective passage of waste material through the feed inlet 11 and achieve pre-treatment crushing, refer to Figure 4 As shown, multiple slitting blades 27 are fixedly connected at equal intervals on the inner side of the feed inlet 11, and multiple through cuts 22 that are aligned and cooperate with the slitting blades 27 are equally spaced on the flip plate 21. It should be noted that the slitting blades 27 extend a portion out of the feed inlet 11.

[0033] When the flipping pallet 21 flips and fits into the feed inlet 11, the cutting blade 27 cuts into the through cut 22, which facilitates the initial cutting of the waste pushed by the flipping pallet 21 into multiple segments, thus making it easier for the waste to pass through the feed inlet 11.

[0034] In a further specific implementation plan, to prevent some debris from leaking directly out from the through incision 22, refer to Figure 9 As shown, the device also includes an inclined guide plate 5, which is inclined and positioned below the tilting tray 21. The inclined guide plate 5 is fixedly connected to the crusher 3. An auxiliary inlet is provided on the top of the crusher 3 near the inclined guide plate 5. The inclined guide plate 5 is used to catch the crushed material leaking from the through cut 22 and guide the crushed material into the crusher 3 through the auxiliary inlet.

[0035] In some specific implementation schemes, refer to Figure 1 and Figure 9 As shown, the dust collection mechanism 4 includes a negative pressure dust collection device 41, a main dust collection pipe 42, a secondary dust collection pipe 46, and an adjustable external dust collection component. The negative pressure dust collection device 41 can be installed on the top of the dustproof housing 1, and the negative pressure dust collection device 41 can be a vacuum cleaner or an industrial negative pressure pump. The main dust collection pipe 42 is connected to the negative pressure end of the negative pressure dust collection device 41, and the main dust collection pipe 42 extends into the dustproof housing 1 and is positioned above the crusher 3. The bottom port of the main dust collection pipe 42 is equipped with a dust collection port. Two sets of adjustable external dust collection components are provided and symmetrically distributed on both sides of the flip tray 21. The adjustable external dust collection components are connected to the main dust collection pipe 42 through the secondary dust collection pipe 46.

[0036] Among them, reference Figure 8 As shown, the adjustable external vacuum assembly includes a square box 43 and a sealing plug 44. The square box 43 is fixedly connected to the dustproof housing 1 via a bracket and is vertically distributed on the side of the flip tray 21. The auxiliary vacuum pipe 46 is fixedly connected to the top of the square box 43, and the diameter of the auxiliary vacuum pipe 46 is smaller than the cross-sectional width of the square box 43. Multiple negative pressure suction nozzles 431 are longitudinally and equidistantly distributed on the side of the square box 43 near the flip tray 21. The sealing plug 44 is fitted inside the square box 43 and is used to seal the auxiliary vacuum pipe 46. The sealing plug 44 and the extension end of the hydraulic telescopic rod 24 are raised and lowered synchronously. Specifically, a connecting rod 45 can be fixedly connected between the sealing plug 44 and the lifting frame 25 connected to the extension end of the hydraulic telescopic rod 24. A sealing ring can be installed at the position where the connecting rod 45 passes through the auxiliary vacuum pipe 46.

[0037] When the tilting pallet 21 is in a horizontal position and ready for loading, the sealing plug 44 is located near the bottom of the square strip box 43. After the waste material is loaded onto the tilting pallet 21 and the hydraulic telescopic rod 24 is controlled to retract and drive the tilting pallet 21 to tilt and feed the material, the negative pressure dust collection device 41 is activated. The negative pressure dust collection device 41 generates negative pressure suction at the ports of the main dust collection pipe 42 and the auxiliary dust collection pipe 46. The square strip box 43, which is connected to the auxiliary dust collection pipe 46, is suctioned by the distributed negative pressure nozzles 431, which facilitates the removal of dust scattered around the tilting pallet 21 during the tilting process and the dust emitted during the crushing and extrusion process. Dust is sucked in to prevent it from polluting the surrounding environment. The main dust suction pipe 42 is directly above the crusher 3, that is, inside the dustproof housing 1, to facilitate the suction of dust generated by the waste material entering the crusher 3 for crushing. During the retraction of the hydraulic telescopic rod 24, the sealing plug 44 is gradually raised. When the flipping plate 21 is attached to the sealing feed inlet 11, the sealing plug 44 blocks the port of the auxiliary dust suction pipe 46. This allows the negative pressure to be concentrated at the port of the main dust suction pipe 42, which facilitates the thorough treatment of dust generated during the crushing process of the crusher 3 and achieves dust prevention.

[0038] Additionally, it should be noted that the size of the sealing plug 44 can be between the cross-sectional dimensions of the auxiliary suction pipe 46 and the square strip box 43. Of course, the sealing plug 44 can also be made to have the same cross-sectional dimensions as the inner cavity of the square strip box 43, and the bottom of the square strip box 43 is provided with a balancing air hole. In this way, the sealing plug 44 gradually rises relative to the square strip box 43 as the flipping tray 21 gradually approaches the feed inlet 11, ensuring that the negative pressure is exerted through the negative pressure suction nozzle 431 close to the flipped tray 21. Because the space below the flipped tray 21 has less dust, it may mainly be concentrated between the flipped tray 21 and the feed inlet 11.

[0039] In some specific implementation schemes, refer to Figure 3 As shown, a crushing roller 32 is installed at the top of the crusher 3. Two crushing rollers 32 are arranged in pairs to perform primary crushing of the falling waste. A rotating crushing blade 33 is set on one side of the bottom of the crusher 3. An inclined plate is set below the crushing roller 32 to guide the falling crushed material to slide towards the rotating crushing blade 33, which facilitates secondary crushing of the material. The recovery port 31 is set below the rotating crushing blade 33 to facilitate the discharge of crushed material and recycling. A bag can be placed at the recovery port 31, and a screen can be set between the recovery port 31 and the rotating crushing blade 33 to prevent excessively large crushed material from being discharged directly.

[0040] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: First, place the fixed construction and decoration waste that needs to be crushed, such as tiles and bricks, on the tilting pallet 21. Then, start the control hydraulic telescopic rod 24 to retract. The telescopic end of the hydraulic telescopic rod 24 pulls the rotating connecting slider 262 through the lifting frame 25. The connecting slider 262 then drives the tilting pallet 21 to tilt towards the feed inlet 11. During this process, the connecting slider 262 rotates relative to the lifting frame 25 and slides along the connecting guide rail 261 away from the rotation axis of the tilting pallet 21, thereby gradually rotating the tilting pallet 21 from a horizontal position to a vertical position that fits the feed inlet 11. During the flipping process of the tilting pallet 21, the connecting slider 262 slides along the connecting guide rail 261, thus driving the first rack 263 to move synchronously. The first rack 263 drives the transmission gear 264 to rotate, and the transmission gear 264 drives the second rack 265 to move. The second rack 265 drives the corresponding crushing clamp 23 to move towards the middle position of the tilting pallet 21. In this way, the crushing clamps 23 on both sides of the tilting pallet 21 can clamp the material in the middle, making it easy to crush extra-long waste materials. 23 When the flipping pallet 21 moves to the vertical plane where the feed inlet 11 is accessible, the crushing clamp 23, which moves from both sides of the flipping pallet 21 toward the middle, enters the opening range of the feed inlet 11. At this time, the crushing clamp 23 cuts into the feed inlet 11, which can avoid collision with the side wall of the dustproof housing 1. Finally, when the flipping pallet 21 closes and seals the feed inlet 11, the crushing clamp 23 also cuts completely into the feed inlet 11, which makes it convenient for waste materials to be effectively fed into the feed inlet 11 even if they are too long, and at the same time, it also achieves preliminary crushing.

[0041] At the same time, when the flipping pallet 21 flips and fits into the feed inlet 11, the cutting blade 27 cuts into the through cut 22, which facilitates the initial cutting of the waste pushed by the flipping pallet 21 into multiple segments, so that the waste can pass through the feed inlet 11.

[0042] Furthermore, during the flipping process of the pallet 21, the negative pressure dust collection device 41 generates negative pressure suction at the ports of both the main dust collection pipe 42 and the auxiliary dust collection pipe 46. The square box 43, which is connected to the auxiliary dust collection pipe 46, relies on the distributed negative pressure suction nozzles 431 to suction, which facilitates the suction of dust scattered around the pallet 21 during the flipping process and dust emitted during the crushing process, preventing dust pollution of the surrounding environment. The main dust collection pipe 42 directly suctions the space above the crusher 3, i.e., inside the dustproof housing 1, which facilitates the suction of dust generated by the waste material entering the crusher 3 for crushing. During the retraction of the hydraulic telescopic rod 24, the sealing plug 44 gradually rises. When the pallet 21 is attached to the sealing feed inlet 11, the sealing plug 44 blocks the port of the auxiliary dust collection pipe 46. This allows the negative pressure to be concentrated at the port of the main dust collection pipe 42, which facilitates the thorough treatment of dust generated by the waste material entering the crusher 3, thus achieving dust prevention.

[0043] Finally, the scrap material is discharged from recycling port 31, making it convenient to directly pack it into bags for processing.

[0044] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
