[0002] With the development of society and the improvement of people's living standards, there are more and more types of garbage, and the methods of garbage disposal are constantly developing, so that more garbage can be recycled, thereby reducing the waste of resources. However, there is a lot of solid waste in life. Due to its fixed structure, it is inconvenient to recycle. Therefore, it needs to be crushed and pre-treated before recycling.

[0003] In the prior art, a crushing device is usually used to recycle and pre-process solid waste. When the crushing teeth are used to crush the garbage, the solid garbage is easily stuck on the crushing teeth, which will reduce the crushing effect of the crushing teeth on the subsequent solid garbage.

[0033] A partition 112 is fixedly connected to the middle position inside the sleeve 11, and two augers 9 with opposite rotation directions are rotatably connected on both sides of the partition 112. The setting of the augers 9 can transport the solid waste preliminarily crushed by the crushing teeth 21 from the middle to the two sides of the crushing shaft 8, avoiding the solid waste from being concentrated in the middle position and unable to be fully crushed by the crushing knife 7 on the crushing shaft 8, thereby improving the efficiency of solid waste crushing.

[0034] The driving mechanism includes a bracket 6, a motor 5, a belt 4 and a pulley 3. Two brackets 6 are provided and are symmetrically fixed to the outer wall of the processing box 1. Motors 5 are fixed inside the brackets 6. The output shaft of one motor 5 is directly fixed to the transmission shaft of one of the augers 9, and the motor 5 directly drives the augers 9 to rotate. The output shaft of the other motor 5 is fixed to pulley 2 10, and pulley 2 10 is fixed to the transmission shaft of the other augers 9. One end of the crushing shaft 8 passes through the processing box 1 and is fixed to pulley 3. A belt 4 is installed between pulley 3 and pulley 2 10. When the motor 5 rotates, the crushing shaft 8 and the augers 9 are driven to rotate at the same time through the cooperation of pulley 3, pulley 2 10 and belt 4, thereby simultaneously realizing the conveying of solid waste by the augers 9 and the rotation and crushing of solid waste by the crushing knife 7.

[0035] A collection box 12 is fixedly connected to the top of the sleeve 11, and the collection box 12 is connected to the sleeve 11. A discharge port is provided at a position corresponding to the collection box 12 on the upper guide plate 2. The guide plate 2 is inclined. A discharge trough 111 is provided at the lower end of the sleeve 11. After the solid waste is initially crushed by the crushing teeth 21, it is centrally guided by the guide plate 2 at the top to slide into the collection box 12, and then enters the sleeve 11 from the collection box 12.

[0036] The cutting mechanism includes a cutting plate 16, a pull rod 23, a rotating plate 22 and a moving frame 15. A plurality of cutting plates 16 are provided and are respectively arranged between adjacent crushing teeth 21. The cutting plates 16 cooperate with the rotation of the crushing teeth 21 to cut off both sides of the solid garbage stuck on the crushing teeth 21, so as to prevent the garbage from being stuck on the crushing teeth 21 and affecting the crushing effect of the solid garbage. A right-angle hook is provided at one end of the cutting plate 16 close to the crushing teeth 21. The right-angle hook is arranged downward and the bottom of the right-angle hook is arranged in a cone shape. When part of the garbage cannot be completely cut off by the cutting plate 16, the right-angle hook can clamp the solid garbage when the cutting plate 16 moves away from the crushing teeth 21, thereby pulling the solid garbage off the crushing teeth 21.

[0037] The other ends of the multiple cutting plates 16 all slide through the inner wall of the processing box 1 and are commonly fixed with a T-shaped plate 26. The moving frame 15 is fixed to the other end of the T-shaped plate 26. A fixed cover 13 is also fixed to the outer wall of the processing box 1. The moving frame 15 is slidably installed inside the fixed cover 13. The upper and lower ends of the moving frame 15 are fixed with guide rods 151. The fixed cover 13 is provided with a guide groove that cooperates with the guide rod 151. A rack is provided on the inner wall of the moving frame 15. A gear 14 is rotatably installed on the fixed cover 13. The gear 14 is a half gear and the gear 14 is meshed with the rack. The gear 14 is driven by a motor. When the gear 14 rotates, since the gear 14 is meshed with the rack, it will drive the moving frame 15 to move back and forth, and the moving frame 15 drives the cutting plate 16 to move back and forth through the T-shaped plate 26.

[0038] A fixed plate 25 is provided above the cutting plate 16, and the fixed plate 25 is fixedly connected to the inner wall of the processing box 1, and there are two fixed plates 25, and the two fixed plates 25 are respectively rotatably connected with a rotating plate 22, and the opposite side walls of the two rotating plates 22 are respectively fixedly connected with elastic ropes 24, and a pull rod 23 with a triangular cross-section is provided between the elastic ropes 24, and a spring 20 is fixedly connected between the fixed plate 25 and the inner wall of the processing box 1. When the crushing teeth 21 rotate to crush the solid waste, the pull rod 23 cooperates with the rotation of the crushing teeth 21 to pull the solid waste stuck on the crushing teeth 21 off the crushing teeth 21. Since the rotating plate 22 is rotatably connected and the elastic rope 24 is elastic, the pull rod 23 has a certain swing angle, and further the pull rod 23 can effectively detach from the rotating crushing teeth 21 to prevent the pull rod 23 from being stuck by the rotating crushing teeth 21. The spring 20 can make the pull rod 23 follow the crushing teeth 21 and then reset after swinging a certain angle.

[0039] The cleaning mechanism includes a motor 19, a hard brush 28 and a disc 33. The motor 19 is fixedly connected to the upper end of the processing box 1 and is electrically connected to the controller. The motor 19 can be automatically controlled by the controller or manually controlled. The output shaft of the motor 19 passes through the processing box 1 and extends to the inside of the processing box 1. The end of the output shaft is fixedly connected to the disc 33. The lower end of the disc 33 is fixedly connected to the hard brush 28. The rotation of the motor 19 drives the disc 33 to rotate, and the disc 33 drives the hard brush 28 to rotate, so as to comprehensively clean the residual solid waste on the crushing teeth 21 to avoid affecting the subsequent crushing effect of the crushing teeth 21 on the solid waste.

[0040] The lubrication mechanism includes an oil injection ring 27, an oil tank 18, a transition pipe 31 and a plug pipe 39. The oil injection ring 27 is sleeved on the outside of the hard brush 28. A connecting frame 32 is fixedly connected between the oil injection ring 27 and the disc 33. The oil tank 18 is fixedly connected to the inner wall of the processing box 1. An oil pipe 29 is installed inside the oil tank 18. A pump body 30 is installed at one end of the oil pipe 29 away from the oil tank 18. One end of the transition pipe 31 is connected to the pump body 30. The pump body 30 and the transition pipe 31 are respectively fixedly connected to the inside of the processing box 1 through a connecting block. An oil injection component and a control component are arranged inside the transition pipe 31. The oil tank 18 is connected to the processing box 1 through the oil pipe with the cooperation of the pump body 30. 29 and the transition pipe 31 inject the lubricating oil in the oil tank 18 into the oil injection ring 27, and the oil injection ring 27 sprays the lubricating oil onto the hard brush 28. The hard brush 28 can apply lubricating oil to the crushing tooth 21 while cleaning the residual solid garbage on the crushing tooth 21. On the one hand, it can prevent the crushing tooth 21 from rusting, increase the service life of the crushing tooth 21, ensure the sharpness of the crushing tooth 21, and improve the crushing effect of the solid garbage. On the other hand, it can make the surface of the crushing tooth 21 relatively smooth, so that the subsequent cutting mechanism can more easily pull the solid garbage stuck on the crushing tooth 21 off the crushing tooth 21.

[0041] The oil filling assembly includes a connecting column 48, a blocking column 34, a plug 39, a baffle 35 and a second spring 36. The connecting column 48 is fixedly connected to the inner wall of the pipeline of the transition pipe 31. The blocking column 34 is fixedly connected to the connecting column 48. The blocking column 34 is used to block the internal pipeline of the plug 39 to prevent the plug 39 from not being plugged into the socket 273 when the pump body 30 is pumping oil, and the oil directly flows out of the plug 39, causing waste. The baffle 35 is fixedly connected to the plug 39 and the baffle 35 is slidably connected to the inner wall of the pipeline of the transition pipe 31. A fixing ring 38 is fixedly connected to the inner wall of the pipeline opening of the transition pipe 31, and the plug 39 slides through the fixing ring 38. The end of the plug 39 away from the baffle 35 is set in an arc shape and has an oil filling port. The second spring 36 is sleeved on the outside of the plug 39 and fixed to the baffle The setting of spring 236 between the plug tube 39 and the fixing ring 38 can make the plug tube 39 automatically disengage from the plug sleeve 273 and reset after the oil injection is completed. The diameter of the baffle 35 is larger than the diameter of the plug tube 39. The baffle 35 is provided with a through hole 37 connected to the plug tube 39. The fixing ring 38 is provided with an air valve 49. When the pump body 30 pumps oil into the transition pipe 31, since the inner wall diameter of the pipe of the plug tube 39 is smaller than the inner wall diameter of the pipe of the transition pipe 31, the flow rate of the plug tube 39 is smaller than the flow rate of the transition pipe 31. Therefore, when the oil enters the plug tube 39, it will also drive the plug tube 39 to move towards the direction close to the plug sleeve 273 under the action of the baffle 35, so that the plug tube 39 is plugged and matched with the plug sleeve 273 to realize oil injection into the injection ring 27.

[0042] The fuel injection ring 27 is provided with a socket 273 that matches the insert pipe 39. The socket 273 is provided with a port connected to the inner cavity of the fuel injection ring 27. A cross 272 is fixedly connected to the inside of the fuel injection ring 27. Both the cross 272 and the fuel injection ring 27 are provided with fuel injection ports 271.

[0043] The control assembly includes a light emitter 41, a light receiver 40, a slide 42 and a slide plate 47. The light emitter 41 and the light receiver 40 are both electrically connected to the controller. The light emitter 41 is installed at the end of the transition pipe 31 close to the injection ring 27. The light receiver 40 is installed on the side wall of the injection ring 27. The position of the light receiver 40 corresponds to the plug sleeve 273. The cooperation of the light receiver 40 and the light emitter 41 can ensure that the plug pipe 39 can be automatically aligned with the plug sleeve 273 when the injection ring 27 is injected with oil, thereby ensuring stable and efficient injection of oil. The slide 42 is arranged on the inner wall of the transition pipe 31 and is located between the baffle 35 and the fixing ring 38. The slide 42 is provided in the inner wall of the transition pipe 31. A piston plate 43 is slidably connected to the part, and a moving rod 44 is fixedly connected to one end of the piston plate 43. The moving rod 44 slides through the transition tube 31, and a slide plate 47 is fixedly connected to the transverse part of the moving rod 44. The end of the transition tube 31 is located above the light emitter 41 and is fixedly connected to a fixing rod 45. The slide plate 47 slides through the fixing rod 45, and a spring three 46 is sleeved on the slide plate 47. The spring three 46 is fixedly connected between the moving rod 44 and the fixing rod 45. The setting of the slide plate 47 can block the light emitted by the light emitter 41 after the oil injection is completed, thereby preventing the controller from automatically controlling the disc 33 to stop when the disc 33 rotates, affecting the crushing work of the crushing teeth 21.

[0044] How it works

[0045] When the solid waste is recycled and pre-processed, the insert tube 39 and the insert sleeve 273 are separated at this time, and will not affect the rotation of the oil injection ring 27. At the same time, the slide plate 47 is in a position to block the light emitted by the light emitter 41, and will not affect the opening and closing of the motor 2 19. The switch of the motor 2 19 is manually turned on. When the motor 2 19 is started, it drives the disc 33 to rotate, and the disc 33 drives the hard brush 28 to rotate, so as to comprehensively clean the residual solid waste on the crushing tooth 21 to avoid affecting the subsequent crushing effect of the crushing tooth 21 on the solid waste. When the crushing tooth 21 rotates to the position where the cutting mechanism is located, the gear 14 is driven by the motor, and when the gear 14 rotates, it drives the moving frame 15 to move back and forth, and the moving frame 15 drives the cutting through the T-shaped plate 26. The cutting plate 16 moves back and forth, and the cutting plate 16 cooperates with the rotation of the crushing teeth 21 to cut off both sides of the solid garbage stuck on the crushing teeth 21, so as to avoid the garbage being stuck on the crushing teeth 21 and affecting the crushing effect of the solid garbage. When part of the garbage cannot be completely cut off by the cutting plate 16, the right-angle hook can clamp the solid garbage when the cutting plate 16 moves away from the crushing teeth, thereby pulling the solid garbage off the crushing teeth 21; when the crushing teeth 21 rotate to the position of the pull rod 23, the pull rod 23 cooperates with the rotation of the crushing teeth 21 to pull the solid garbage stuck on the crushing teeth 21 off the crushing teeth 21, so as to more effectively remove the solid garbage from the crushing teeth 21, thereby avoiding reducing the subsequent crushing effect of the crushing teeth 21 on the solid garbage;

[0046] After the solid waste is initially crushed by the crushing teeth 21, it is guided by the guide plate 2 at the top to slide into the collection box 12, and then enters the sleeve 11 from the collection box 12. The two motors 5 are started to drive the auger 9 to rotate. When the auger 9 rotates, the solid waste is transported from the middle position to the two sides of the crushing shaft 8. At the same time, with the cooperation of pulley 1 3, pulley 2 10 and belt 4, the crushing shaft 8 is synchronously driven to drive the crushing knife 7 to rotate, and the solid waste is crushed again to improve the crushing effect of the solid waste. Finally, a group of guide plates 2 at the bottom will concentrate the solid waste again to facilitate subsequent collection and processing.

[0047] When it is necessary to apply lubricating oil to the crushing teeth 21, the switch of the motor 2 19 is manually turned on again. When the motor 2 19 drives the disc 33 and the oil injection ring 27 to rotate, the optical receiver 40 on the oil injection ring 27 rotates to a position corresponding to the position of the optical transmitter 41, and the optical receiver 40 transmits a signal to the controller, which immediately and automatically controls the motor 2 19 to be turned off. At the same time, the pump body 30 is started, and the pump body 30 pumps the lubricating oil in the oil tank 18 into the pipeline of the transition pipe 31 through the oil pipe 29. In the initial state, under the action of the spring 2 36, the internal pipeline of the plug 39 is inserted by the blocking column 34. This prevents the plug 39 from flowing out directly from the plug 39 when the plug 39 has not yet moved to the plug sleeve 273 under the push of the oil. When the oil enters the transition pipe 31, it will push the baffle 35 to drive the plug 39 to compress the spring 2 36 and move toward the plug sleeve 273. When the arc-shaped end of the plug 39 is plugged into the plug sleeve 273, the plug 39 stops moving under the obstruction of the plug sleeve 273, and the oil injection port of the plug 39 injects oil into the port of the plug sleeve 273, thereby spraying oil to the hard brush 28 through the oil injection ring 27, and the hard brush 28 lubricates the crushing tooth 21 with oil during the subsequent rotation.

[0048] When the oil filling is completed, the pump body 30 stops pumping oil, and the insert tube 39 moves in the direction away from the sleeve 273 under the action of the second spring 36, so that the other end of the insert tube 39 is engaged with the blocking column 34 again. When the insert tube 39 moves in the direction away from the sleeve 273, a negative pressure will be formed inside the slide groove 42, so that the piston plate 43 drives the moving rod 44 to move downward, and the moving rod 44 compresses the spring three 46 to drive the slide plate 47 to move downward. The slide plate 47 blocks the light emitted by the light emitter 41 to avoid affecting the opening and closing of the motor when the solid waste is crushed later. When oil is filled again, the baffle 35 drives the insert tube 39 to move in the direction close to the sleeve 273 under the drive of the oil, and the baffle 35 pushes the gas inside the transition pipe 31 to move into the slide groove 42, thereby pushing the piston plate 43 to move upward, thereby driving the slide plate 47 to move upward under the cooperation of the third spring 46, and no longer blocking the light emitter 41, and oil filling is realized again later.
