[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Please see the appendix Figure 1-6 This application provides the following technical solutions.
[0025] The waste system crushing and decomposition mechanism includes a crushing mechanism 1 and a screening mechanism 2. The screening mechanism 2 is fixedly connected to the bottom of the crushing mechanism 1. The screening mechanism 2 includes a screening box 21 and a buffer plate 22. The buffer plate 22 is rotatably connected to one side of the screening box 21 via a rotating shaft. An installation groove 29 is provided on one side of the screening box 21. A screening plate 23 is provided on the inner wall of the installation groove 29. The screening plate 23 is inclined. A filter groove 24 is provided on the top of the buffer plate 22. A rotating rod 28 is fixedly connected to the side of the buffer plate 22 away from the rotating shaft of the screening box 21. Rotating grooves 26 are provided on both sides of the screening box 21. The rotating grooves 26 are arc-shaped. Buffer components 27 are provided at both ends of the rotating rod 28 passing through the two rotating grooves 26. The screening box 21 has a screening port 210 on the side away from the installation chute 29, and a discharge port is provided at the bottom of the screening box 21. A guide plate 25 is movably installed on the inner wall of the discharge port, and the guide plate 25 passes through the two ends of the screening box 21 and is threaded with fixing nuts.
[0026] It should be noted that when the crushed waste material and impurities fall to the top of the screen 233, the standard particles fall to the top of the guide plate 25 after being screened by the screen 233. After being guided by the guide plate 25, they flow into the receiving equipment. The larger waste material and impurities that do not meet the standards roll from the top of the mounting frame 231 to the screening port 210 and are discharged to the side opposite to the guide plate 25. The operator can re-inject or otherwise process the discharged material. The buffer 27 includes a shrink tube 272 and a rotating ring 275. The inner wall of the rotating ring 275 is rotatably connected to the rotating rod 28. The top of the rotating ring 275 is fixedly connected to a pull rod 274. The upper part of the pull rod 274 is movably inserted into the shrink tube 272 through anti-detachment blocks. The outer wall of the pull rod 274 located inside the shrink tube 272 is provided with a spring 273. The top of the shrink tube 272 is fixedly connected to a rotating block 271. One side of the rotating block 271 is rotatably connected to the screening box 21.
[0027] It should be noted that larger waste materials and impurities cannot pass through the filter tank 24 and directly impact the buffer plate 22, causing the buffer plate 22 to rotate. This causes the rotating rod 28 to move along the inner wall of the rotating groove 26, which in turn causes the rotating ring 275 to rotate on the outer wall of the rotating rod 28. This causes the pulling rod 274 to slide downward along the inner wall of the contraction tube 272. The anti-detachment quick-pressing spring 273 generates compression deformation, which can further offset the impact force. Subsequently, the larger waste materials and impurities roll down from the lower position to the top of the screen 233. After the impact ends, the spring 273 extends and releases elastic potential energy, causing the pulling rod 274 to pull the buffer plate 22 to move and reset, in order to resist the next impact.
[0028] The screening plate 23 includes a mounting frame 231, the thickness of which is equal to that of the mounting groove 29. The mounting frame 231 is slidably connected to the inner wall of the mounting groove 29. A handle 232 is fixedly connected to the outer side of the mounting frame 231 located in the mounting groove 29. A screen 233 is provided on one side of the mounting frame 231 located inside the screening box 21. The screen 233 is located below the buffer plate 22. Both sides of the mounting frame 231 are provided with locking blocks 234. When the mounting frame 231 is located inside the mounting groove 29, the side wall of the screening box 21 is between the mounting frame 231 and the locking blocks 234. At the same time, one end of the mounting frame 231 is inserted into the screening port 210 and overlaps the lower side. The orientation of the guide plate 25 is opposite to that of the mounting frame 231.
[0029] It should be noted that when a lot of impurities accumulate on the top of the screen 233 and affect filtration, the operator can pull the handle 232 to slide the screening plate 23 out obliquely upward from the inner wall of the installation groove 29. After cleaning and maintenance are completed, the screening plate 23 is reinserted so that the screening box 21 is in the fixed groove formed by the locking block 234 and the installation frame 231.
[0030] The crushing mechanism 1 includes a support frame 11, a crushing box 12 is fixedly connected to the top of the support frame 11, a crushing roller 14 is rotatably connected to the inner wall of the crushing box 12, and a feeding box 13 is fixedly connected to the top of the crushing box 12.
[0031] It should be noted that the operator first uses equipment to divide the waste material into sizes that can be put into the top of the feeding box 13, and then the waste material enters the crushing box 12 from the feeding box 13. The crushing roller 14 is then activated to crush the waste material, and the crushed material falls through the gap of the crushing roller 14 into the screening box 21.
[0032] In operation, the operator first uses equipment to cut the waste material into sizes that can be fed into the top of the feeding box 13. The waste material then enters the crushing box 12 from the feeding box 13. The crushing roller 14 is activated to crush the waste material. The crushed material falls through the gaps in the crushing roller 14 into the screening box 21, reaching the top of the buffer plate 22. Smaller waste materials are filtered by the filter tank 24 and fall directly onto the screen 233. Larger waste materials and impurities cannot pass through the filter tank 24 and directly impact the buffer plate 22, causing it to rotate. This rotates the rotating rod 28 along the inner wall of the rotating groove 26, causing the rotating ring 275 to rotate on the outer wall of the rotating rod 28. This causes the pulling rod 274 to slide downwards along the inner wall of the contraction tube 272. The anti-detachment quick-pressing spring 273 generates compression deformation, thus further offsetting the impact force. Subsequently, larger waste materials and impurities roll from the lower position to the top of the screen 233, impacting... After the impact, the spring 273 extends and releases its elastic potential energy, causing the pull rod 274 to pull the buffer plate 22 to move and reset, resisting the next impact. When the crushed waste material and impurities fall to the top of the screen 233, the standard particles fall to the top of the guide plate 25 after being screened by the screen 233. After being guided by the guide plate 25, they flow into the receiving equipment. The larger waste material and impurities that do not meet the standards roll from the top of the mounting frame 231 to the screening port 210 and are discharged to the side opposite to the guide plate 25. The operator can put the discharged material back in or process it separately. When a lot of impurities accumulate on the top of the screen 233 and affect filtration, the operator can pull the handle 232 to slide the screening plate 23 obliquely upward from the inner wall of the mounting groove 29. After cleaning and maintenance, the screening plate 23 is reinserted, so that the screening box 21 is in the fixed groove formed by the locking block 234 and the mounting frame 231.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
