Technical Field

[0001] This application relates to the field of crusher technology, specifically to a solid waste crusher and a solid waste treatment system. Background Technology

[0002] A solid waste crusher is a machine used to crush solid waste, such as urban construction waste (also known as construction debris). Currently designed solid waste crushers are large in size, occupy a lot of space, require significant space for application, and are inconvenient to transport. Therefore, there is an urgent need to design a compact and small-sized solid waste crusher. Utility Model Content

[0003] This application provides a solid waste crusher and a solid waste treatment system, the main purpose of which is to make the solid waste crusher more compact and smaller.

[0004] According to a first aspect of this application, a solid waste shredder is provided, comprising:

[0005] The machine casing is equipped with a feeding port;

[0006] Two crushing structures are spatially spaced apart. Each crushing structure includes a power unit and a pendulum unit. The power unit includes a drive shaft fixed inside the housing. The pendulum unit includes multiple hammer plates and multiple hammer heads. The multiple hammer plates are spaced apart and fixed to the drive shaft. The hammer heads and hammer plates are rotatably connected.

[0007] Along the axial direction of the drive shaft, the hammers on different drive shafts are staggered, and the space between two adjacent drive shafts forms a feeding area. The feeding port is used to provide solid waste to the feeding area.

[0008] The hammer head has a retracted state and an extended state. When the drive shaft rotates, the hammer head is in the extended state, and when the drive shaft does not rotate, the hammer head is in the retracted state.

[0009] In one embodiment, the hammer plate has multiple circumferentially spaced mounting holes, and the pendulum unit further includes multiple hammer rods. The number of hammer rods does not exceed the number of mounting holes. The hammer rods pass through the mounting holes and are sleeved on the multiple hammer plates, and the multiple hammer rods are parallel to the drive shaft. An assembly cavity or an empty cavity is formed between adjacent hammer plates. The assembly cavities and empty cavities on the same crushing structure are staggered, and the assembly cavities on different crushing structures are staggered. The hammer head is rotatably sleeved with the hammer rod at the assembly cavity.

[0010] In one embodiment, the pendulum unit further includes a sleeve that is fitted over the hammer rod in the vacant cavity.

[0011] In one embodiment, an even number of mounting holes are provided on the hammer plate, and the number of hammer rods is half the number of mounting holes. Multiple hammer rods that are sleeved on the same hammer plate are distributed circumferentially at intervals.

[0012] In one embodiment, the power unit further includes a plurality of bushings, which are sleeved on the transmission shaft between adjacent hammer plates.

[0013] In one embodiment, the power unit further includes a disc, and two discs are configured. The two discs are respectively sleeved and fixed to both ends of the transmission shaft inside the housing, and there are gaps between the disc and the side wall of the housing and between the disc and the hammer plate.

[0014] In one embodiment, one end of the hammer head is rotatably connected to the hammer plate, and the other end is provided with an arc-shaped sidewall.

[0015] In one embodiment, an auxiliary opening and closing power component is further included. The housing includes a front housing and a rear housing that are detachably connected. One end of the auxiliary opening and closing power component is fixed to the front housing, and the other end is fixed to the rear housing. The auxiliary opening and closing power component is used to assist the rear housing in opening and closing relative to the front housing. One of the crushing structures is fixed to the front housing, and the other crushing structure is fixed to the rear housing.

[0016] In one embodiment, the crushing structure on the rear housing is higher than the crushing structure on the front housing.

[0017] In one embodiment, the system further includes a base, with the front housing and the base fixedly connected, and the rear housing and the base rotatably connected.

[0018] In one embodiment, the device further includes a feeding bin, which is fixed to the outer side wall of the front housing, and the feeding port is provided on the feeding bin; and / or, a guide is provided at the bottom of the housing, which is used to assist the processed solid waste from flowing out of the housing.

[0019] In one embodiment, the crushing structure further includes a plurality of guide bars, which are fixed side by side inside the housing and are closer to the feed port than the hammer plate. The plurality of guide bars are used to disperse the clumps of solid waste to prevent the solid waste from entangled in the drive shaft and / or the hammer head.

[0020] In one embodiment, the guide bar and the empty cavity on the same crushing structure are positioned correspondingly, and a first guide gap is formed between the guide bar and the empty cavity; a second guide gap is formed between the hammer on one crushing structure and the empty cavity on another crushing structure.

[0021] According to a second aspect of this application, a solid waste treatment system is provided, comprising a first conveyor belt, a solid waste crusher, a second conveyor belt, a drum screen, a third conveyor belt, an air separation room, and a sorting room connected in sequence, wherein the solid waste crusher is the aforementioned solid waste crusher.

[0022] In one embodiment, a fourth conveyor belt is further included, which traverses the sorting chamber, with one end extending to the air separation chamber and connecting with the third conveyor belt, and the other end extending to the outside of the sorting chamber; a sorting space is provided on the bottom side of the sorting chamber away from the top, and the sorting space is divided into multiple collection areas from the side closer to the air separation chamber to the side farther away from the air separation chamber, and each collection area is provided with a conveyor belt, each conveyor belt being used to transport different types of processed solid waste.

[0023] According to the solid waste crusher in the above embodiment, two spaced-apart crushing structures are arranged in space. The drive shaft of each crushing structure is fixed inside the machine casing, and multiple hammer plates are fixed on each drive shaft at axial intervals. A hammer head is rotatably fixed on each hammer plate. The hammer heads on different drive shafts are staggered along the axial direction of the drive shaft, and the hammer heads have a retracted state and an extended state. When the drive shaft rotates, the hammer head is in the extended state. When the drive shaft does not rotate, the hammer head is in a naturally suspended state due to its own weight, and the space it occupies is retracted compared to the extended state. This makes the two crushing structures more compact in space, which facilitates a more compact and miniaturized solid waste crusher and also facilitates the transportation of the manufactured solid waste crusher.

[0040] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0041] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0042] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0043] One embodiment of this application provides a solid waste crusher 200, which is mainly used to crush urban construction waste into smaller blocks or granular structures for screening in subsequent processing. Of course, the solid waste crusher 200 can also crush other types of solid waste, such as rural solid waste (further, for example, rural solid fertilizer).

[0044] Please see Figures 1-13 The solid waste crusher 200 includes: a housing 10 and two crushing structures 20.

[0045] The housing 10 has a feeding port 10a on its shell wall.

[0046] Two crushing structures 20 are spatially spaced apart. Each crushing structure 20 includes a power unit 21 and a pendulum unit 22. The power unit 21 includes a drive shaft 215 fixed inside the housing 10. The pendulum unit 22 includes multiple hammer plates 221 and multiple hammer heads 222. The multiple hammer plates 221 are spaced apart and fixed to the drive shaft 215. Multiple circumferentially spaced mounting holes 2211 are opened on the hammer plates 221. At least some of the mounting holes 2211 are provided with hammer heads 222. The hammer heads 222 and hammer plates 221 are rotatably connected.

[0047] Along the axial direction of the drive shaft 215, the hammers 222 on different drive shafts 215 are staggered, and the space between two adjacent drive shafts 215 forms a feeding zone. The feeding port 10a is used to provide solid waste to the feeding zone.

[0048] The hammer head 222 has a retracted state and an extended state. When the drive shaft 215 rotates, the hammer head 222 is in the extended state. When the drive shaft 215 does not rotate, the hammer head 222 is in a naturally suspended state due to its own weight, and the space it occupies is in the retracted state compared to the extended state.

[0049] The solid waste crusher 200 described in the above embodiment features two spaced-apart crushing structures 20. The drive shaft 215 of each crushing structure 20 is fixed within the housing 10. Multiple hammer plates 221 are axially spaced and fixed on each drive shaft 215, with a hammer head 222 rotatably fixed on each hammer plate 221. The hammer heads 222 on different drive shafts 215 are staggered along the axial direction of the drive shaft 215, and each hammer head 222 has a retracted state and an extended state. When the drive shaft 215 rotates, the hammer head 222 is in the extended state; when the drive shaft 215 does not rotate, the hammer head 222 is in the retracted state. This design makes the two crushing structures 20 more compact in space, facilitating a more compact and miniaturized solid waste crusher 200, and also facilitating the transportation of the manufactured solid waste crusher 200.

[0050] The hammer plate 221 has multiple circumferentially spaced mounting holes 2211, and at least some of the mounting holes 2211 are provided with hammer heads 222. For example, the hammer plate 221 has six circumferentially spaced mounting holes 2211, and hammer heads 222 can be rotatably fixed at all six mounting holes 2211, or hammer heads 222 can be rotatably fixed at only one mounting hole 2211, or hammer heads 222 can be rotatably fixed at four of the mounting holes 2211.

[0051] Specifically, in some embodiments, an even number of mounting holes 2211 are provided on the hammer plate 221, and multiple hammer heads 222 rotatably connected to the same hammer plate 221 are circumferentially spaced. For example, six circumferentially spaced mounting holes 2211 are provided on the hammer plate 221, and three hammer heads 222 rotatably connected to the same hammer plate 221 are circumferentially spaced. In this case, the six mounting holes 2211 on the hammer plate 221 are divided into two groups, one group is used to connect the hammer heads 222, and the other group is left empty. The empty group of mounting holes 2211 can be used as spare holes. For example, if the mounting holes 2211 at the hammer heads 222 are worn or damaged due to long-term use and cannot be used, three hammer heads 222 can be rotatably fixed to the hammer plate 221 at the other group of mounting holes 2211.

[0052] Please see Figure 6 In addition to multiple circumferentially spaced mounting holes 2211 on the hammer plate 221 for rotatable connection with the hammer head 222, the hammer plate 221 also has a shaft hole 2212 at its center. The hammer plate 221 is sleeved and fixed to the drive shaft 215 through the shaft hole 2212. To facilitate the connection between the hammer plate 221 and the drive shaft 215, a keyway is also provided at the shaft hole 2212 of the hammer plate 221, and a corresponding keyway is also provided on the drive shaft 215. The connection between the hammer plate 221 and the drive shaft 215 is achieved by the cooperation of a pin and the keyways on both sides.

[0053] Please see Figures 7-8 In some embodiments, the hammer 222 corresponds to both its retracted and extended states. One end of the hammer 222 is rotatably connected to the hammer plate 221, while the other end has an arc-shaped sidewall. When the hammer 222 comes into contact with solid waste via the arc-shaped sidewall at its end, combined with the rotatable connection between the hammer 222 and the hammer plate 221, the hammer 222 exhibits good flexibility and can be adaptively adjusted according to the shape or size of the solid waste. This reduces the likelihood of jamming and facilitates smoother and more efficient crushing of solid waste.

[0054] Please see Figure 3 Specifically, in some embodiments, the power unit 21 includes a power component 211, a drive wheel 212, a driven wheel 213, a transmission belt 214, a transmission shaft 215, a support base 216, and a protective cover 217.

[0055] The power component 211 is, for example, a motor. The motor's power shaft is connected to the drive wheel 212. The drive wheel 212 is indirectly connected to the driven wheel 213 via a transmission belt 214. The driven wheel 213 is connected to the transmission shaft 215. There are two support seats 216, each of which is fixed with a bearing. The two ends of the transmission shaft 215 are respectively sleeved with the bearings on the support seats 216.

[0056] To make the structure of the housing 10 more compact and small, the drive wheel 212, driven wheel 213, transmission belt 214, support base 216, and protective cover 217 are all located outside the housing 10. Loading plates or platforms can be installed on the side walls of the housing 10 to support and fix the support base 216. The protective cover 217 is fitted over the drive wheel 212, driven wheel 213, and transmission belt 214 to provide dust protection.

[0057] When the power unit 21 is working, the power component 211 is started. The power component 211 synchronously drives the drive wheel 212 to rotate. After the drive wheel 212 rotates, it will synchronously drive the transmission belt 214, the driven wheel 213, the transmission shaft 215 and the hammer plate 221 to rotate. At this time, the hammer head 222 on the hammer plate 221 is in the unfolded state and can strike the solid waste in the feeding area.

[0058] For a better option, please refer to Figure 5 and Figure 11 The power unit 21 also includes a disc 218, which is configured as two discs. The two discs 218 are respectively sleeved and fixed to both ends of the transmission shaft 215 inside the housing 10, and there are gaps between the disc 218 and the side wall of the housing 10, as well as between the disc 218 and the hammer plate 221.

[0059] Urban construction solid waste typically includes sand, steel wire, etc. If it is not properly managed or treated, this waste can easily get tangled on the hammer plate 221 (referring to the hammer plate 221 closest to the end of the drive shaft 215) and the housing 10, and then enter the bearing, causing the bearing to jam or even the machine to jam.

[0060] The designed disc 218 effectively guides waste such as sand and steel wire, keeping solid waste away from the side wall of the housing 10 or turning it into the housing 10, so that it can be processed by the pendulum unit 22 and enter the next stage. Specifically, the disc 218 is, for example, an anti-winding flange.

[0061] At the point where the drive shaft 215 is not fitted with the hammer plate 221, the outer wall of the drive shaft 215 is exposed inside the housing 10. If it is not protected, solid waste can easily damage the exposed outer wall of the drive shaft 215, causing severe wear or aggravating the wear of the drive shaft 215 and shortening its service life.

[0062] Based on this, for a better option, please refer to Figure 5The power unit 21 also includes multiple bushings 219, which are sleeved on the outside of the drive shaft 215 between adjacent hammer plates 221. The bushings 219 effectively protect the outer wall of the drive shaft 215 that is not sleeved on the hammer plates 221, effectively extending the service life of the drive shaft 215, and thus extending the service life of the power unit 21 and the solid waste crusher 200 using the power unit 21.

[0063] Please see Figure 5 In some embodiments, the pendulum unit 22 further includes multiple hammer rods 223, the number of which does not exceed the number of mounting holes 2211. The hammer rods 223 pass through the mounting holes 2211 and are sleeved with multiple hammer plates 221, and all hammer rods 223 are parallel to the drive shaft 215, meaning the multiple hammer rods 223 are circumferentially spaced relative to the hammer plates 221. Assembly cavities or empty cavities are formed between adjacent hammer plates 221. Assembly cavities and empty cavities on the same crushing structure 20 are staggered, and assembly cavities on different crushing structures 20 are staggered. The hammer head 222 is rotatably sleeved with the hammer rods 223 at the assembly cavity, and indirectly rotatably sleeved with the hammer plate 221 through the hammer rods 223. When an even number of mounting holes 2211 are provided on the hammer plate, the number of hammer rods 223 can be half the number of mounting holes 2211. In this case, the multiple hammer rods 223 sleeved with the same hammer plate 221 are circumferentially spaced.

[0064] Two fragmented structures 20 are spatially spaced and staggered, for example, Figure 5 As shown, there are two crushing structures 20 horizontally staggered at different heights. Each crushing structure 20 includes eight hammer plates 221, which are equally spaced along the axial direction of the drive shaft 215. The eight hammer plates 221 form four assembly cavities and four empty cavities, which are staggered. In the upper crushing structure 20, the assembly cavities are formed in the first, third, fifth, and seventh cavities, and the empty cavities are formed in the second, fourth, sixth, and eighth cavities. In the lower crushing structure 20, the empty cavities are formed in the first, third, fifth, and seventh cavities, and the assembly cavities are formed in the second, fourth, sixth, and eighth cavities. It can be understood that the order here is from left to right. Correspondingly, the first hammer plate 221 in the upper crushing structure 20 is aligned with the first hammer plate 221 in the lower crushing structure 20, and the eighth hammer plate 221 in the upper crushing structure 20 is aligned with the eighth hammer plate 221 in the lower crushing structure 20.

[0065] Since the hammer head 222 is not sleeved on the hammer rod 223 in the empty cavity, the hammer rod 223 in this position is exposed inside the housing 10 and is easily in contact with solid waste. It is worn by the impact of solid waste. Therefore, it is preferable that the pendulum unit 22 also includes a rod sleeve 224, which is sleeved on the outside of the hammer rod 223 in the empty cavity. The rod sleeve 224 effectively protects the hammer rod 223 in the empty cavity and extends the service life of the hammer rod 223.

[0066] Please see Figures 1-4 In some embodiments, the solid waste crusher 200 further includes an auxiliary opening and closing power component 30, and the housing 10 includes a front housing 11 and a rear housing 12 that are detachably connected. One end of the auxiliary opening and closing power component 30 is fixed to the front housing 11, and the other end is fixed to the rear housing 12. The auxiliary opening and closing power component 30 is used to assist the rear housing 12 in opening and closing relative to the front housing 11.

[0067] Specifically, for example, the front housing 11 and the rear housing 12 are detachably connected by multiple nuts and screws at their close end faces, or the front housing 11 and the rear housing 12 are detachably connected by a snap-fit. This application does not limit the specific detachable connection method, as long as the front housing 11 and the rear housing 12 can be detachably connected.

[0068] When a component inside the housing 10 of the solid waste crusher 200 needs to be replaced or repaired, the rear housing 12 needs to be opened. The rear housing 12 has a certain weight, and operating it manually would be slow or require several workers. In this case, the auxiliary opening / closing power component 30 can save manpower and quickly open or close the rear housing 12. The auxiliary opening / closing power component 30 can be, for example, a hydraulic cylinder. More specifically, a hydraulic cylinder has a piston cylinder and a piston fitted together, with the end of the piston cylinder away from the piston fixed to the front housing 11, and the end of the piston away from the piston cylinder fixed to the rear housing 12.

[0069] The system includes two crushing structures 20, one fixed to the front housing 11 and the other fixed to the rear housing 12. More preferably, the crushing structure 20 on the rear housing 12 is higher than the crushing structure 20 on the front housing 11, allowing the two crushing structures 20 to be spatially spaced, such as... Figure 1 As shown, the two crushing structures 20 are not only spaced apart in height (vertical direction), but also spaced apart in width (horizontal direction). This makes full use of the space inside the casing 10, making the two crushing structures 20 more compact and facilitating the compact and miniaturized design of the solid waste crusher 200.

[0070] Please see Figures 1-4The solid waste crusher 200 also includes a base 60. The front housing 11 is fixedly connected to the base 60, and the rear housing 12 is rotatably connected to the base 60. The base 60 is, for example, made of steel, and has a certain structural strength to provide support for the housing 10 on it. The front housing 11 and the base 60 are fixedly connected, for example, by threaded connection or welding. The two sides of the rear housing 12 away from the front housing 11 are rotatably connected to the base 60. For example, a support plate is provided on the end face of the base 60 facing the housing 10, and the rotating shaft passes through the support plate and holes opened in the side wall of the rear housing 12 to achieve the rotatable connection between the rear housing 12 and the base 60. The base 60 facilitates the direct use of the solid waste crusher 200 without the need for further installation and fixing operations.

[0071] Please see Figure 1 After the base 60 is installed, the power component 211 of the crushing structure 20 on the front housing 11 can be fixed on the base 60, reducing the load on the housing 10. Since the crushing structure 20 on the rear housing 12 is higher than the crushing structure 20 on the front housing 11, a corresponding platform or plate can be provided on the outer side wall of the rear housing 12 to facilitate the fixing of the corresponding power component 211 in the rear housing 12.

[0072] Please see Figures 1-4 The solid waste crusher 200 also includes a feeding bin 40, which is fixed to the outer wall of the front housing 11. A feeding port 10a is provided on the feeding bin 40. Specifically, the feeding bin 40 is a chamber with a certain volume. The feeding port 10a is provided on the side wall of the feeding bin 40. When feeding through the feeding bin 40, the amount of solid waste conveyed each time can be increased, or some solid waste can be temporarily stored in the space inside the feeding bin 40, thereby improving the solid waste conveying efficiency or reducing the number of solid waste conveying operations. In other embodiments, if the feeding bin 40 is not provided, the corresponding feeding port 10a can be directly provided on the side wall of the housing 10.

[0073] Please see Figures 1-2 A guide 50 is provided at the bottom of the housing 10, near the end close to the base 60. The guide 50 assists in the outflow of processed solid waste from the housing 10. The guide 50 only needs to guide the solid waste processed by the pendulum unit 22. The specific structure of the guide 50 can be, for example, multiple parallel rod-shaped members, relatively distributed guide plates, or a funnel-shaped structure. When the base 60 is provided, the base 60 can be an empty shell, with the guide 50 placed inside the base 60, and the solid waste directly enters the base 60 through the guide 50. In other embodiments, if the base 60 is not provided, and the housing 10 is suspended and fixed to the ground, the solid waste is piled on the ground through the guide 50, or piled on a storage box or conveying structure on the ground.

[0074] Please see Figures 1-3 as well as Figures 10-12 In some embodiments, the crushing structure 20 also includes a plurality of guide bars 23, which are fixed side by side inside the housing 10 and are closer to the feed port 10a than the hammer plate 221. The plurality of guide bars 23 are used to disperse the clumps of solid waste to prevent the solid waste from getting tangled in the drive shaft 215 and / or the hammer head 222.

[0075] Multiple guide bars 23 arranged side by side, for example Figure 10 As shown, the guide bars 23 in the two breaking structures 20 are distributed, for example as follows: Figure 1 As shown, the guide bar 23 on the rear housing 12 is located between the hammer plate 221 and the feeding bin 40, and the guide bar 23 on the front housing 11 is also located between the hammer plate 221 and the feeding bin 40. In this way, when solid waste is conveyed into the housing 10, the multiple guide bars 23 arranged side by side on each crushing structure 20 can effectively disperse the clumps or large piles of solid waste. The dispersed smaller solid waste flows through the gap between two adjacent guide bars 23 and enters the feeding area, effectively avoiding the phenomenon of solid waste entanglement on the drive shaft 215 and effectively avoiding the phenomenon of jamming or stalling. The guide bar 23 better ensures the smooth use and working efficiency of the solid waste crusher 200.

[0076] Preferably, the guide rods 23 on the same crushing structure 20 correspond to the positions of the empty cavities, and a first guide gap is formed between the guide rods 23 and the hammer rods 223 in the empty cavities to avoid unnecessary hard collisions or jamming between the guide rods 23 and the hammer rods 223 in the empty cavities. A second guide gap is formed between the hammer head 222 on one crushing structure 20 and the hammer rods 223 in the empty cavities of another crushing structure 20 to avoid unnecessary hard collisions or jamming between the hammer head 222 and the hammer rods 223 in the empty cavities of another crushing structure 20.

[0077] It should be noted that the two crushing structures 20 are the same in terms of overall structural composition and connection method. However, the hammers 222 in the two crushing structures 20 are in different orientations and need to be staggered. Similarly, the guide bars 23 in the two crushing structures 20 are in different orientations and also need to be staggered.

[0078] More preferably, the crushing structure 20 also includes a screw adjuster 24, and the guide bar 23 is connected to the screw adjuster 24. The screw adjuster 24 is used to adjust the angle or orientation of the guide bar 23 within the housing 10, so that the guide bar 23 can be adapted to solid waste crushers 200 of different sizes, thereby improving the flexibility or adaptability of the guide bar 23.

[0079] For a better option, please refer to Figures 9-10The guide rod 23 includes a sheath 231 and a fixed shaft 232, and the screw adjuster 24 includes an adjusting seat 241, a screw 242, a nut 243 and a connector 244.

[0080] The guide rods 23 and the sheaths 231 are arranged in a one-to-one correspondence, and the guide rods 23 and the sheaths 231 are fixedly connected. The sheaths 231 separate two adjacent guide rods 23. The fixed shaft 232 passes through multiple sheaths 231 and multiple guide rods 23. The fixed shaft 232 and the sheaths 231 can be engaged by keyways and pins. The adjusting seat 241 can be fixed to the outer wall of the housing 10. One end of the screw 242 is rotatably connected to the adjusting seat 241, and the other end of the screw 242 is a free end. The nut 243 is threadedly connected to the screw 242. The connecting piece 244 is a plate-shaped connecting piece. One end of the connecting piece 244 is detachably connected to the nut 243, and the other end of the connecting piece 244 is connected to the fixed shaft 232. Before using the solid waste crusher 200, the orientation or angle of the guide bars 23 can be adjusted according to the size of the solid waste. Specifically, this is achieved by changing the position of the nut 243 relative to the screw 242, which changes the orientation or angle of the multiple guide bars 23 within the casing 10. Since the screw 242 and the adjusting seat 241 are rotatably connected, the guide bars 23 can also be adaptively adjusted according to the actual size of the solid waste input during subsequent use of the solid waste crusher 200. Multiple guide bars are connected via the same fixed shaft 232, effectively simplifying the angle adjustment structure. Taking four guide bars 23 arranged side-by-side on the same fixed shaft 232 as an example, in actual use, depending on wear, all four guide bars 23 can be replaced as a whole in the same batch, or a single guide bar 23 can be replaced individually according to the actual situation, making it more flexible in use.

[0081] Because the hammers 222 in different crushing structures 20 are staggered, and the hammers 222 are fixed to the hammer rods 223 in the assembly cavity, the guide rods 23 and the hammer rods 223 in the empty cavity are positioned correspondingly. The guide rods 23 in one crushing structure 20 correspond to the hammers 222 in another crushing structure 20. At this time, a certain gap is also provided between the guide rods 23 and the corresponding hammers 222. When the guide rods 23 in one crushing structure 20 correspond to the hammers 222 in another crushing structure 20, it facilitates the hammers 222 striking solid waste without dead angles, improving the crushing effect and increasing crushing efficiency.

[0082] The operating principle of the solid waste shredder 200 is explained below:

[0083] The power units 21 in the two crushing structures 20 are activated, causing the hammers 222 in the pendulum unit 22 to operate inside the casing 10 and be in an deployed state. At this time, with Figure 1For example, the hammer 222 in the upper crushing structure 20 rotates clockwise with the drive shaft 215, and the hammer 222 in the lower crushing structure 20 rotates counterclockwise with the drive shaft 215.

[0084] Mixed solid waste to be processed is conveyed into the feeding area inside the casing 10 through the feeding port 10a.

[0085] After solid waste enters the housing 10, it first touches the upper and lower sets or rows of guide bars 23. The guide bars 23 guide the solid waste between the two drive shafts 215, preventing long strips of material from getting tangled in the drive shafts 215 and / or hammers 222. Material smaller than the gap reserved by the guide bars 23 (i.e., solid waste) will pass directly through. Material larger than the gap reserved by the guide bars 23 piles up on the guide bars 23. The hammers 222 inside the front housing 11 protrude from the gap reserved by the guide bars 23 and strike the bottom layer of material on the guide bars 23. Among them, the material close to the drive shaft 215 and the direction of the hammers 222 is first fluffed up by the hammers 222, so that the material is fluffed up and struck in an orderly manner. Material smaller than the gap reserved by the upper and lower drive shafts 215 is fluffed up in an orderly manner and accelerates to impact the lower guide member 50. Material larger than the pre-reserved gap between the upper and lower drive shafts 215 will be repeatedly struck by the hammers 222 on the upper and lower drive shafts 215 to make the material more fluffy. The material then impacts the lower guide 50, and the fluffed material falls to the discharge port below the guide 50 and is then transported by the conveyor belt to the next sorting stage. It should be noted that the pre-reserved gap of the guide bars 23 refers to the gap between two adjacent guide bars 23, and the pre-reserved gap between the two drive shafts 215 refers to the gap between the hammers 222 on both drive shafts 215 when they are in the extended state and the two hammers 222 are close to each other.

[0086] Solid waste is propelled upwards by the pendulum unit 22 of the front housing 11 to the hammer 222 at the rear housing 12. The solid waste then moves between the hammers 222 of the two crushing structures 20 and is struck again. After being struck, the solid waste moves to the guide member 50.

[0087] As a variety of mixed solid wastes enter the casing 10, due to differences in the hardness, type, and size of the materials, hard materials such as bricks, tiles, stones, and glass are effectively broken into sizes suitable for the next stage through repeated impacts.

[0088] Because the upper and lower pendulum units 22 are designed with corresponding gaps, they will not break soft materials. However, after the soft materials are hit by the hammers 222, they will become fluffy. This will cause the soft materials such as bags, wood, and plastics that are in clumps to fluff up and accelerate to hit the guide 50, so that this type of soft material can be effectively separated from other materials. Preserving the integrity of the soft materials helps to sort them in the next step.

[0089] Please see Figure 5In the figure, the upper and lower crushing structures 20 are close to each other, and the upper and lower hammers 222 are distributed alternately. There are a total of eight hammers 222 between the two crushing structures 20 on the side that are close to each other. From left to right, the gap between the hammers 222 and the hammer rod 223 will form a wavy gap path, which can improve the crushing effect of solid crushed materials.

[0090] Please see Figures 1-13 In another embodiment of this application, a solid waste treatment system is provided, including a first conveyor belt 100, a solid waste crusher 200, a second conveyor belt 300, a drum screen 400, a third conveyor belt 500, an air separation room 600, and a sorting room 700 connected in sequence. The solid waste crusher 200 is the solid waste crusher 200 in the above embodiment.

[0091] The solid waste treatment system also includes a fourth conveyor belt 800, which traverses the sorting chamber 700. One end of the fourth conveyor belt 800 extends to the air classifier 600 and connects with the third conveyor belt 500, while the other end extends to the outside of the sorting chamber 700. A sorting space is located on the bottom side of the sorting chamber 700 away from the top. This sorting space is divided into multiple collection zones from the side closest to the air classifier 600 to the side furthest away from it. Each collection zone contains a conveyor belt, and each conveyor belt is used to transport different types of processed solid waste.

[0092] Specifically, the end of the fourth conveyor belt 800 furthest from the air classifier 600 extends to the outside of the sorting chamber 700. Above the fourth conveyor belt 800 outside the sorting chamber 700, a powerful automatic magnetic separator 900 is installed. Magnetic components are placed on the powerful automatic magnetic separator 900 to attract magnetic metals. The powerful automatic magnetic separator 900 can attract more magnetic metals by rotating the conveyor belt. The drum screen 400 is a shaftless drum screen. A first transfer belt 410 can be installed below the drum screen 400, and a second transfer belt 420 is connected to its end. Inside the air classifier 600, the fourth conveyor belt 800 is equipped with an anti-winding fan 610 and a guide wheel 620. For example, three collection areas are set below the sorting room 700. For ease of description, the three collection areas are the first collection area 710, the second collection area 720 and the third collection area 730. The first collection area 710 is equipped with a first conveyor belt 711, the second collection area 720 is equipped with a second conveyor belt 721 and the third collection area 730 is equipped with a third conveyor belt 731.

[0093] The operating principle of the solid waste treatment system is explained below:

[0094] The side of the first conveyor belt 100 away from the solid waste crusher 200 is a material storage area. Material is picked up by a loader and fed onto the first conveyor belt 100. The first conveyor belt 100 transports the material to the feed port 10a of the solid waste crusher 200 and puts it into the casing 10.

[0095] After the solid waste crusher 200 crushes the incoming material, it flows out through the guide 50 into the second conveyor belt 300. The second conveyor belt 300 continues to transport the material to the drum screen 400. The drum screen 400 discharges the fine sand and gravel powder to the first transfer belt 410 directly below. The first transfer belt 410 transports the fine sand and gravel powder to the second transfer belt 420.

[0096] Large particles of material are conveyed through the drum screen 400 to the third conveyor belt 500. The third conveyor belt 500 continues to convey the material to the fourth conveyor belt 800. The fourth conveyor belt 800 uses the anti-winding fan 610 and the air separation guide wheel 620 to screen light materials into the air separation chamber 600, while the remaining materials enter the sorting chamber 700.

[0097] The sorting room 700 has three collection areas, each equipped with a sorter. The sorter in the first collection area 710 sorts light materials / combustible materials to the first conveyor belt 711, the sorter in the second collection area 720 sorts wood to the second conveyor belt 721, and the sorter in the third collection area 730 sorts rubber / plastic to the third conveyor belt 731.

[0098] After passing through the sorting chamber 700, the magnetic metals in the remaining material are adsorbed and collected by the powerful automatic iron remover 900. The remaining material is then transported by the fourth conveyor belt 800 and piled up. This part of the material is mostly brick slag aggregate, which can then be processed by specialized machines or operators.

[0099] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
