A torsion spring A is installed between the two ends of the ratchet 10, one side of the ratchet 10 is rotatably connected to the eccentric shaft 12, one end of the eccentric shaft 12 controls the hydraulic device 21 to work through the transmission assembly 13, the hydraulic device 21 includes a sleeve 201, a sealing plug 202, a special-shaped tube 203, a telescopic tube 204, an oil storage tank 205, an oil delivery pipe 206 and an oil inlet pipe 207, the sleeve 201 is fixedly connected to the extrusion plate 7, the outer side of the sealing plug 202 is slidably connected to the inner wall of the sleeve 201, the sealing plug 202 is fixedly connected to the special-shaped tube 203, the special-shaped tube 203 is connected to the telescopic tube 204 and the oil storage tank 205, and the oil storage tank 205 is fixedly connected to the housing 1 The oil storage tank 205 is connected with the telescopic tube 204, the oil pipeline 206 and the oil inlet pipe 207. The inside of the special-shaped tube 203 and the oil pipeline 206 are both installed with a one-way valve 208. One end of the telescopic tube 204 and the oil inlet pipe 207 are both installed with valves. The transmission assembly 13 includes a push-pull plate 131, a movable part 132, a straight rod 133 and a piston 134. The push-pull plate 131 is rotatably connected to the eccentric shaft 12, and the movable part 132 is rotatably connected to the push-pull plate 131 through a rotating shaft. The two ends of the straight rod 133 are fixedly connected to the movable part 132 and the piston 134 respectively, and the piston 134 and the straight rod 133 are both slidably connected to the special-shaped tube.

[0031] When in use, firstly, the cans to be cut and crushed are put into the crushing area of ​​the shell 1 from the feed port 104 of the shell 1. At the same time, the rotating shaft 2 is driven to rotate by the driving motor 301. Since the two rotating shafts 2 are respectively fixed to the two synchronous wheels 302, and the two synchronous wheels 302 are connected by a multi-groove belt transmission, when one of the rotating shafts 2 rotates, the two rotating shafts 2 can rotate synchronously under the action of the transmission connection of the two synchronous wheels 302, and then the two rotating shafts 2 drive the two-layer tool group 4 to rotate, and each layer of the tool group 4 includes a plurality of spaced crushing knives 40. 1, and the crushing knife 401 of the knife set 4 includes a straight blade knife 4011 and a serrated knife 4012. When the serrated knife 4012 rotates, its serrated structure can grasp the surface of the can when it contacts the can. When the knife disc 402 drives the serrated knife 4012B to rotate, the serrated teeth are like a saw, and the can is torn by repeated biting and tearing actions. In particular, for the top and bottom of the can, which have a more complex structure, the serrated knife 4012 can effectively tear them apart. For example, the pull ring of the can may be torn apart by the serrated knife 4012. 12, the serrations of the cutter 4011 bite the can, and then it is torn off as the cutter rotates; when the cutter disc 402 equipped with the straight-edged cutter 4011 starts to rotate, the straight-edged cutter 4011 rotates rapidly with the cutter disc 402, and after the can enters the crushing chamber, the straight-edged cutter 4011 contacts the can with its sharp blade. Due to the fast rotation speed, the blade exerts a strong cutting force on the can, just like cutting an object with a knife. The straight-edged cutter 4011 can cut the barrel of the can along the axial or circumferential direction. For example, for a complete can, the straight-edged cutter 4011A may first cut the body of the can into several long strips of fragments. The straight-edged tool 4011 and the serrated tool 4012 cooperate with each other in the crushing process. The straight-edged tool 4011A mainly cuts the main part of the can, while the serrated tool 4012 focuses on tearing the complex structural parts of the can. For example, after the straight-edged tool 4011 cuts the body of the can into larger fragments, the serrated tool 4012 can further tear and refine the edges or connecting parts of these fragments, thereby improving the overall crushing effect.

[0032] Next, the crushed can fragments pass through the gaps between the rollers 503 and enter the bottom of the frame 502, and then fall onto the baffle 6. When the can fragments at the baffle 6 accumulate to a certain amount, the gravity of the can fragments will force the baffle 6 to open. At this time, the baffle 6 drives the rotating shaft relative to it to rotate, causing the torsion spring B to undergo elastic deformation. When the can fragments fall into the compaction area 102, the elastic deformation force of the torsion spring B is used to reset the baffle 6. Therefore, whenever the can fragments at the baffle 6 accumulate to a certain amount, the baffle 6 will open to collect the can fragments in the compaction area 102.

[0033] Next, when the can fragments in the compacting area 102 reach a predetermined value, the drive motor 301 is started to drive the rotating shaft 2 to reverse. On the one hand, the rotating shaft 2 can drive the straight-edged tool 4011 and the serrated tool 4012 to rotate in the opposite direction. During the crushing process, some tough materials, such as plastic film, may be entangled on the tool. When the serrated tool 4012 rotates in the opposite direction, the reverse movement of the saw teeth can help clean up these entangled materials, because the reverse rotating saw teeth will make the entangled materials receive a force opposite to the winding direction, making it easier to fall off the serrated tool 4012, thereby reducing the equipment failure rate caused by material entanglement. For the materials that have been initially crushed, the reverse rotating serrated tool 4012 can cut them again, and some larger fragments can be removed by the reverse rotating saw teeth. Under the action of the teeth, the material will be cut again from different angles to further refine the material. If some materials, such as waste materials containing sticky components, are blocked on the blade of the straight-edged tool 4011 during the crushing process, the reverse rotation can help clean the blade. When the straight-edged tool 4011 rotates in the reverse direction, the material blocked on the blade will be subjected to the reverse force, causing it to loosen and fall off the blade, keeping the blade clean and ensuring that the cutting performance of the tool is not affected. In addition, for some irregularly shaped materials, the reverse rotating long-cut tool can cut the material from different angles. After forward rotation cutting, some materials may not be fully crushed due to their shape or position. When rotating in the reverse direction, the tool can contact these materials at a new angle for additional cutting, thereby improving the crushing effect and uniformity of the material.On the other hand, when the rotating shaft 2 rotates in the opposite direction, the pawl 11 and the ratchet 10 can cooperate with each other, and the pawl 11 can drive the ratchet 10 to rotate, and the ratchet 10 drives the eccentric shaft 12 to do circular motion, and the eccentric shaft 12 drives the transmission component 13 to work, and the piston 134 in the transmission component 13 moves back and forth linearly along the inner wall of the special-shaped tube 203. When the piston 134 rises, the pressure in the special-shaped tube 203 is reduced, the one-way valve 208 in the special-shaped tube 203 is closed, and the one-way valve 208 in the oil pipeline 206 is opened, and the hydraulic oil in the oil storage tank 205 enters the special-shaped tube 203 through the oil pipeline 206. Conversely, when the piston 134 descends, the pressure in the special-shaped tube 203 is increased, the one-way valve 208 in the special-shaped tube 203 is opened, and the one-way valve 208 in the oil pipeline 206 is closed, and the hydraulic oil in the special-shaped tube 203 enters the upper end of the sleeve 201. At this time, the hydraulic oil is located above the sealing plug 202, and the position of the special-shaped tube 203 remains unchanged. Under the action of the hydraulic pressure, the extrusion plate 7 begins to rise and squeezes the fragments in the compaction area 102 and performs compaction work. At this time, the two baffles 6 are closed. During the extrusion process, the can fragments located above support the two baffles 6, and the baffles 6 contact the inner top wall of the compaction area 102, making the baffles 6 more stable, which is conducive to the normal compaction work. The compacted cans save space and are convenient for subsequent transportation. In addition, during the compaction process, since a number of filter holes 8 are opened in the extrusion plate 7, the water in the cans will fall into the water collection area 103 through the filter holes 8, and then enter the collection box 22 from the drainage port of the water collection area 103 along the inclined surface at the bottom of the water collection area 103, and finally open the valve to discharge the water from the drainage pipe at the bottom of the collection box 22. ;

[0034] Finally, after the compaction work is completed, the driving motor 301 is used to drive the rotating shaft 2 to rotate forward again. During the relative rotation of the ratchet 10 and the pawl 11, the ratchet 10 will not rotate. During the rising process of the extrusion plate 7, since the spring 20 will be in a stretched state, when the ratchet 10 does not rotate, the elastic force of the spring 20 will drive the extrusion plate 7 to drop to its original position, and then pull the handle at the sealing plate 24 to drive the two sealing plates 24 to move, and the compacted cans can be taken out.
