Description

Technical Field

[0001] The present invention relates to the technical field of waste battery recycling, and specifically to a safe dismantling and recycling device for lead-acid batteries of new energy vehicles. Background Art

[0002] Lead-acid batteries are a common type of battery, widely used in fields such as automobiles, motorcycles, and UPS power supplies. Lead-acid batteries are composed of positive and negative plates, electrolyte, and a plastic container. Since they contain harmful substances, special attention needs to be paid to safety and environmental protection during recycling and treatment.

[0003] The patent with the patent announcement number CN218005002U relates to a device for recycling and utilization of waste lead-acid batteries by crushing, including a crushing chamber and a pretreatment box. Beneficial effects: This patent adopts a pretreatment box. When staff recycle waste lead-acid batteries, the waste lead-acid batteries can be put into the pretreatment box. The waste lead-acid batteries slide below the puncturing needle. The hydraulic cylinder starts to extend, pushing the puncturing needle to pierce the outer shell of the waste lead-acid battery. At the same time, the push plate moves upward due to the obstruction of the outer shell of the lead-acid battery, and the spring is compressed. The puncturing needle pierces the waste lead-acid battery, and the internal sulfuric acid and water flow out. The hydraulic rod shortens, pulling the mounting plate and the puncturing needle upward. The spring rebounds, pushing the push plate to push the punctured waste lead-acid battery off the surface of the puncturing needle. The sulfuric acid and water flow out along the water-permeable holes into the water receiving tank, completing the liquid discharge of the lead-acid battery, avoiding sulfuric acid corrosion of the roll crusher and subsequent treatment equipment, extending the service life of the equipment and the safety of the crushing treatment, and improving the recycling and crushing treatment efficiency.

[0004] In the above patent, it has the function of preprocessing lead-acid batteries. By using a hydraulic cylinder to push a puncturing needle to pierce the outer shell of the lead-acid battery, the sulfuric acid and water inside the lead-acid battery flow out through the water holes, avoiding the corrosion of the roll crusher by sulfuric acid during the crushing of lead-acid batteries, which helps to extend the service life of the roll crusher. However, when using a puncturing needle to pierce the outer shell of the lead-acid battery for liquid discharge, due to the small size of the water holes formed after puncturing, the rate of liquid discharge is slow, thus reducing the working efficiency. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a safe dismantling and recycling device for lead-acid batteries of new energy vehicles, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A safety demolition and recycling device for a lead-acid battery of a new energy vehicle, including a housing, a crushing mechanism is fixedly penetrated inside the housing, a cover plate is rotatably penetrated through the top of the housing, a pull plate is slidably penetrated through the surface of the housing, a hole slot is opened at the bottom of the housing near the pull plate, and a cutting device and a buffer device are also included; wherein, the cutting device includes a driving motor, a push plate, a cutting knife, a circular long rod, a rubber plate, an E-shaped plate and a blocking block. The push plate moves towards the pull plate direction, and the movement of the push plate drives the cutting knife to move towards the pull plate direction. The driving motor is fixedly penetrated through the surface of the housing, the push plate is fixedly installed on the output end of the driving motor, the cutting knife is fixedly installed on the surface of the push plate, the circular long rod is slidably penetrated through the surface of the push plate, the rubber plate is fixedly installed on the surface of the circular long rod, the movement of the push plate drives the circular long rod to move, and the movement of the circular long rod drives the rubber plate to move. The E-shaped plate is slidably penetrated through the surface of the cutting knife, and the blocking block is fixedly installed on the surface of the E-shaped plate close to the circular long rod. By clamping the lead-acid battery with the rubber plate and the pull plate, it is prevented that the lead-acid battery shakes during the cutting by the cutting knife, affecting the stability of the cutting.

[0007] According to the above technical solution, the bottom of the cutting knife contacts the inner wall bottom of the housing. A first spring is arranged between the circular long rod and the push plate. The movement of the push plate stretches the first spring, causing the first spring to be deformed by extrusion. A first corrugation is opened on the surface of the rubber plate away from the circular long rod. The movement of the rubber plate drives the lead-acid battery to move towards the pull plate direction. A second spring is arranged between the E-shaped plate and the cutting knife. A first arc surface is opened on the surface of the blocking block close to the rubber plate. By moving the E-shaped plate towards the cut lead-acid battery direction to expand the cut, it helps to accelerate the outflow rate of the electrolyte liquid from the inside of the lead-acid battery.

[0008] According to the above technical solution, the buffer device includes a fixed plate, a vertical sliding plate, an inclined plate, a sector plate, a contact block, a rotating plate and a bottom plate. The downward movement of the inclined plate drives the vertical sliding plate to move downward, and the downward movement of the vertical sliding plate drives the sector plate to move downward. The fixed plate is fixedly installed on the inner wall of the housing. The vertical sliding plate is slidably penetrated through the top of the fixed plate. The inclined plate is fixedly installed on the top plate of the vertical sliding plate. The sector plate is fixedly installed on the surface of the vertical sliding plate. The contact block is fixedly installed on the surface of the fixed plate close to the vertical sliding plate. The rotating plate is rotatably penetrated through the top of the inclined plate. The bottom plate is fixedly installed on the bottom of the rotating plate. The downward movement of the inclined plate drives the rotating plate to move downward. By controlling the downward movement speed of the lead-acid battery with the inclined plate, it is prevented that the lead-acid battery directly hits the crushing mechanism, which helps to extend the service life of the crushing mechanism.

[0009] According to the above technical solution, a third spring is provided between the vertical slide plate and the fixed plate. The sector plate is elastic. An arc surface two is formed on the surface of the contact block close to the sector plate. During the movement of the surface of the sector plate, it contacts with the arc surface two of the contact block. The bottom of the rotating plate contacts the top of the inclined plate. A first volute spring is provided between the rotating plate and the inclined plate. By changing the rotation angle of the rotating plate and the vibration generated during rotation, it is ensured that the lead-acid battery smoothly enters the crushing mechanism for crushing.

[0010] According to the above technical solution, the lubricating device includes a liquid storage box, a spray head, a rectangular plate, a lifting plate, a rotating column, a stirring blade and an extrusion plate. The downward movement of the lifting plate drives the extrusion plate to move downward. The downward movement of the extrusion plate squeezes the inside of the liquid storage box. The liquid storage box is fixedly penetrated through the inner and outer walls of the housing. The spray head is fixedly penetrated through the surface of the liquid storage box. The rectangular plate is fixedly installed on the top of the inner wall of the liquid storage box. The lifting plate slides through the top of the liquid storage box. The rotating column rotates through the surface of the rectangular plate. The stirring blade is fixedly installed on the surface of the rotating column close to the spray head. The extrusion plate is fixedly installed at the bottom of the lifting plate. Lubricating liquid is provided inside the liquid storage box. A first gear is fixedly installed on the surface of the lifting plate close to the rotating column. A second gear is fixedly installed on the surface of the rotating column close to the lifting plate. The first gear and the second gear are meshed. During the movement of the first gear of the lifting plate, it drives the second gear to rotate. The rotation of the second gear drives the rotating column to rotate. The stirring blade stirs the inside of the liquid storage box to prevent the lubricating liquid inside the liquid storage box from stratifying or settling to the bottom, which helps to improve the lubrication effect of the lubricating liquid.

[0011] According to the above technical solution, a sealing rubber part is provided inside the spray head. The lubricating liquid inside the spray head pushes open the sealing rubber part and sprays towards the output end of the crushing mechanism. A fourth spring is provided between the lifting plate and the liquid storage box. The top of the lifting plate contacts the bottom of the vertical slide plate. The surface of the extrusion plate contacts the surface of the rectangular plate. The surface of the extrusion plate contacts the inner wall of the liquid storage box. Automatic lubrication of the crushing mechanism is achieved through extrusion by the extrusion plate, which reduces the burden on the operator for manual lubrication and helps to extend the service life of the crushing mechanism.

[0012] According to the above technical solution, the recycling device includes a receiving housing, a filter plate, a Z-shaped piece, a pressing plate, a handle, and a limiting plate. The movement of the handle drives the filter plate to move away from the receiving housing, and the surface of the filter plate separates from the surface that contacts the receiving housing during the movement. The receiving housing is fixedly installed at the bottom of the housing. The filter plate is clamped on the inner and outer walls of the receiving housing. The Z-shaped piece is fixedly installed on the inner wall of the receiving housing. The pressing plate is fixedly installed on the surface of the Z-shaped piece. The handle is sleeved on the surface of the filter plate. The limiting plate is fixedly installed on the surface of the receiving housing. The limiting plate performs double limiting on the handle to ensure that the operator can only remove the filter plate for maintenance or replacement under correct operation, effectively improving the safety when replacing the filter plate.

[0013] According to the above technical solution, the Z-shaped piece has elasticity, and the stretched Z-shaped piece resets under the influence of its own elastic force. The surface of the pressing plate contacts the surface of the filter plate. A fifth spring is arranged between the handle and the filter plate. The surface of the handle contacts the surface of the limiting plate. Due to the elasticity of the Z-shaped piece itself, after the operator releases the limit between the handle and the limiting plate, the filter plate can automatically pop out, facilitating the operator to quickly remove the filter plate for maintenance and replacement.

[0014] The present invention provides a safety demolition and recycling device for lead-acid batteries of new energy vehicles. It has the following beneficial effects: (1) For the safety demolition and recycling device of the lead-acid battery of the new energy vehicle, during the movement of the first corrugation of the rubber plate, it contacts the surface of the lead-acid battery. By opening the first corrugation on the rubber plate, the rubber plate can stably clamp the lead-acid battery, preventing the lead-acid battery from shifting during the cutting process and affecting the cutting stability. During the movement of the E-shaped plate, it contacts the inner wall of the cut lead-acid battery. The E-shaped plate is used to expand the cut, enabling the electrolyte liquid inside the lead-acid battery to flow out more quickly, which helps to improve the recycling efficiency of the electrolyte liquid.

[0015] (2) For the safety demolition and recycling device of the lead-acid battery of the new energy vehicle, during the movement of the surface of the sector piece, it contacts the second arc surface of the contact block, causing the sector piece to deform. By intermittently contacting the sector piece and the contact block, the downward movement speed of the inclined plate is controlled, thereby buffering the fall of the lead-acid battery and preventing the lead-acid battery from directly hitting the crushing mechanism and affecting the service life of the crushing mechanism. During the downward movement of the sector piece, intermittent contact with the contact block generates vibration, causing vibration when the rotating plate rotates. By vibrating when the rotating plate changes the inclination, it ensures that the lead-acid battery on the top of the rotating plate can smoothly enter the crushing mechanism, which helps to improve the stable progress of the crushing work.

[0016] (3) The safe dismantling and recycling equipment for lead-acid batteries of new energy vehicles has a stirring blade that rotates to move the lubricating liquid inside the liquid storage box. The stirring blade stirs the lubricating liquid inside the liquid storage box, thereby improving the fluidity of the lubricating liquid inside the liquid storage box and avoiding stratification or sinking of the lubricating liquid, which helps to improve the use effect of the lubricating liquid. The downward movement of the extrusion plate allows the lubricating liquid inside the nozzle to push away the sealing rubber part and spray toward the crushing mechanism. The movement of the extrusion plate realizes automatic lubrication of the crushing mechanism, which reduces the lubrication burden of the operator and reduces the frequency of the operator's hands approaching the crushing mechanism, which helps to improve safety at work.

[0017] (4) The safe dismantling and recycling equipment for lead-acid batteries of new energy vehicles has a limit plate to limit the movement of the handle, and a secondary limit is imposed on the handle through the limit plate, so that the operator can only pull out the filter plate for maintenance and replacement after the secondary limit is released during the operation, thereby ensuring the safety when replacing the filter plate. The movement of the plate drives the filter plate to move away from the receiving shell. Through the elasticity of the Z-shaped piece itself, the filter plate can automatically pop out after the operator releases the limit, saving the operator's time in replacing the filter plate, thereby improving the replacement efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , an embodiment of the present invention is: A safety demolition and recycling device for lead-acid batteries of new energy vehicles, including a housing 1, a crushing mechanism 21 is fixedly penetrated inside the housing 1, a cover plate 22 is rotatably penetrated through the top of the housing 1, a pulling plate 23 is slidably penetrated through the surface of the housing 1, a hole slot is opened at the bottom of the housing 1 near the pulling plate 23, and a cutting device and a buffering device are further included; wherein, the cutting device includes a driving motor 31, a pushing plate 32, a cutting knife 33, a circular long rod 34, a rubber plate 35, an E-shaped plate 36 and a block 37. The output end of the driving motor 31 moves to drive the pushing plate 32 to move towards the pulling plate 23. The movement of the pushing plate 32 drives the cutting knife 33 to move towards the pulling plate 23. The driving motor 31 is fixedly penetrated through the surface of the housing 1. The pushing plate 32 is fixedly installed on the output end of the driving motor 31. The cutting knife 33 is fixedly installed on the surface of the pushing plate 32. The circular long rod 34 is slidably penetrated through the surface of the pushing plate 32. The rubber plate 35 is fixedly installed on the surface of the circular long rod 34. The movement of the pushing plate 32 drives the circular long rod 34 to move towards the pulling plate 23. The movement of the circular long rod 34 drives the rubber plate 35 to move towards the pulling plate 23. The E-shaped plate 36 is slidably penetrated through the surface of the cutting knife 33. The block 37 is fixedly installed on the surface of the E-shaped plate 36 close to the circular long rod 34. The lead-acid battery is clamped by the rubber plate 35 and the pulling plate 23 to prevent the lead-acid battery from shaking during the cutting by the cutting knife 33, which affects the stability of the cutting.

[0022] The bottom of the cutting knife 33 contacts the inner wall bottom of the housing 1. A first spring is arranged between the circular long rod 34 and the push plate 32. The push plate 32 moves to stretch the first spring, causing the first spring to be compressed and deformed. The deformed first spring exerts a reaction force on the circular long rod 34. A first corrugation is provided on the surface of the rubber plate 35 away from the circular long rod 34. During the movement of the first corrugation of the rubber plate 35, it contacts the surface of the lead-acid battery, causing the rubber plate 35 to move and drive the lead-acid battery to move towards the pull plate 23. A second spring is arranged between the E-shaped plate 36 and the cutting knife 33. An arc surface is provided on the surface of the abutting block 37 close to the rubber plate 35. By moving the E-shaped plate 36 towards the cut lead-acid battery, the cut is enlarged, which helps to accelerate the outflow rate of the electrolyte liquid from the inside of the lead-acid battery.

[0023] The buffer device includes a fixed plate 41, a vertical sliding plate 42, an inclined plate 43, a sector piece 44, a contact block 45, a rotating plate 46 and a bottom plate 47. The inclined plate 43 moves downward under the influence of the lead-acid battery. The downward movement of the inclined plate 43 drives the vertical sliding plate 42 to move downward. The downward movement of the vertical sliding plate 42 drives the sector piece 44 to move downward. The fixed plate 41 is fixedly installed on the inner wall of the housing 1. The vertical sliding plate 42 slidably penetrates through the top of the fixed plate 41. The inclined plate 43 is fixedly installed on the top plate of the vertical sliding plate 42. The sector piece 44 is fixedly installed on the surface of the vertical sliding plate 42. The contact block 45 is fixedly installed on the surface of the fixed plate 41 close to the vertical sliding plate 42. The rotating plate 46 rotatably penetrates through the top of the inclined plate 43. The bottom plate 47 is fixedly installed on the bottom of the rotating plate 46. The downward movement of the inclined plate 43 drives the rotating plate 46 to move downward. The downward movement of the rotating plate 46 drives the bottom plate 47 to move downward. The speed of the downward movement of the lead-acid battery is controlled by the inclined plate 43 to prevent the lead-acid battery from directly hitting the crushing mechanism 21, which helps to extend the service life of the crushing mechanism 21.

[0024] A third spring is arranged between the vertical sliding plate 42 and the fixed plate 41. The sector piece 44 is elastic. An arc surface is provided on the surface of the contact block 45 close to the sector piece 44. The downward movement of the vertical sliding plate 42 drives the sector piece 44 to move downward. During the movement of the surface of the sector piece 44, it contacts the arc surface of the contact block 45. The bottom of the rotating plate 46 contacts the top of the inclined plate 43. A first scroll spring is arranged between the rotating plate 46 and the inclined plate 43. By changing the rotation angle of the rotating plate 46 and the vibration generated during rotation, it is ensured that the lead-acid battery smoothly enters the crushing mechanism 21 for crushing.

[0025] When this embodiment is working, the cover plate 22 is manually rotated to move upward, and the lead-acid battery is placed into the interior of the housing 1, such that the bottom of the lead-acid battery contacts the bottom of the inner wall of the housing 1. The drive motor 31 is started, and the output end of the drive motor 31 moves to drive the push plate 32 to move in the direction of the pull plate 23. The movement of the push plate 32 drives the cutting knife 33 to move in the direction of the pull plate 23. The movement of the push plate 32 drives the circular long rod 34 to move in the direction of the pull plate 23. The movement of the circular long rod 34 drives the rubber plate 35 to move in the direction of the pull plate 23. During the movement of the corrugation one of the rubber plate 35, it contacts the surface of the lead-acid battery, such that the movement of the rubber plate 35 drives the lead-acid battery to move in the direction of the pull plate 23. During the movement of the surface of the lead-acid battery, it contacts the surface of the pull plate 23, such that the lead-acid battery is clamped by the rubber plate 35. The push plate 32 continues to move to stretch the first spring, such that the first spring deforms to exert a reaction force on the circular long rod 34, and the lead-acid battery is clamped through the rubber plate 35 to ensure the stable progress of cutting. The push plate 32 continues to move to drive the cutting knife 33 to move in the direction of the pull plate 23. The movement of the cutting knife 33 drives the E-shaped plate 36 to move in the direction of the pull plate 23. The movement of the E-shaped plate 36 drives the abutting block 37 to move in the direction of the pull plate 23. During the movement of the cutting knife 33, it contacts the surface of the lead-acid battery, such that the lead-acid battery is cut by the cutting knife 33, and the electrolyte liquid inside the lead-acid battery flows out through the cut. During the movement of the first arc surface of the abutting block 37, it contacts the surface of the rubber plate 35, such that the movement of the abutting block 37 is affected by the resistance of the rubber plate 35 and moves in the direction of the E-shaped plate 36. The movement of the abutting block 37 drives the E-shaped plate 36 to move backward. During the movement of the E-shaped plate 36, it contacts the inner wall of the cut lead-acid battery, such that the movement of the E-shaped plate 36 drives the cut lead-acid battery to move, and the cut is enlarged through the E-shaped plate 36, which helps to accelerate the outflow rate of the electrolyte liquid; After the electrolyte liquid inside the lead-acid battery is discharged, manually move the pull plate 23 away from the housing 1, so that the surface of the lead-acid battery in contact with the pull plate 23 is separated. Under the influence of the first spring, the rubber plate 35 drives the lead-acid battery to move towards the inclined plate 43. During the movement of the bottom of the lead-acid battery, it is separated from the bottom inner wall of the housing 1. Under the influence of gravity, the lead-acid battery moves downward and contacts the top of the inclined plate 43, causing the inclined plate 43 to move downward under the influence of the lead-acid battery. The downward movement of the inclined plate 43 drives the vertical slide plate 42 to move downward, and the downward movement of the vertical slide plate 42 drives the sector piece 44 to move downward. During the movement of the surface of the sector piece 44, it contacts the second arc surface of the contact block 45, causing the sector piece 44 to deform under the influence of the resistance of the contact block 45. By controlling the downward movement speed of the lead-acid battery through the inclined plate 43, it helps to extend the service life of the crushing mechanism 21. While the inclined plate 43 moves downward, it drives the rotating plate 46 to move downward, and the downward movement of the rotating plate 46 drives the bottom plate 47 to move downward. During the downward movement of the bottom of the bottom plate 47, it contacts the top of the fixed plate 41, causing the inclined plate 43 to continue to move downward and drive the rotating plate 46 to rotate towards the crushing mechanism 21. The rotation of the rotating plate 46 drives the lead-acid battery to move towards the crushing mechanism 21. During the movement of the bottom of the lead-acid battery, the surface in contact with the rotating plate 46 is separated. At the same time, during the downward movement of the sector piece 44, it intermittently contacts the contact block 45 to generate vibration, causing the rotating plate 46 to generate vibration when it rotates. By generating vibration when the rotating plate 46 rotates, it ensures that the lead-acid battery smoothly enters the crushing mechanism 21 for crushing.

[0026] Please refer to Figures 1-9, on the basis of the above embodiments, in another embodiment of the present invention, it further includes a lubricating device and a collecting device; the lubricating device includes a liquid storage box 51, a spray head 52, a rectangular plate 53, a lifting plate 54, a rotating column 55, a stirring blade 56 and a pressing plate 57. The downward movement of the lifting plate 54 drives the pressing plate 57 to move downward. The downward movement of the pressing plate 57 squeezes the inside of the liquid storage box 51. The liquid storage box 51 is fixedly penetrated through the inner and outer walls of the housing 1. The spray head 52 is fixedly penetrated through the surface of the liquid storage box 51. The rectangular plate 53 is fixedly installed at the top of the inner wall of the liquid storage box 51. The lifting plate 54 slides through the top of the liquid storage box 51. The rotating column 55 rotates through the surface of the rectangular plate 53. The stirring blade 56 is fixedly installed on the side of the rotating column 55 close to the spray head 52. The pressing plate 57 is fixedly installed at the bottom of the lifting plate 54. Lubricating liquid is provided inside the liquid storage box 51. A first gear is fixedly installed on the surface of the lifting plate 54 close to the rotating column 55. A second gear is fixedly installed on the surface of the rotating column 55 close to the lifting plate 54. The first gear and the second gear are meshed. During the movement of the first gear of the lifting plate 54, it drives the second gear to rotate. The rotation of the second gear drives the rotating column 55 to rotate. The rotation of the rotating column 55 drives the stirring blade 56 to rotate. The inside of the liquid storage box 51 is stirred by the stirring blade 56 to prevent the lubricating liquid inside the liquid storage box 51 from stratifying or settling to the bottom, which helps to improve the lubrication effect of the lubricating liquid.

[0027] A sealing rubber part is provided inside the spray head 52. The downward movement of the pressing plate 57 causes the lubricating liquid inside the spray head 52 to push open the sealing rubber part and spray towards the output end of the crushing mechanism 21. A fourth spring is provided between the lifting plate 54 and the liquid storage box 51. The top of the lifting plate 54 contacts the bottom of the vertical sliding plate 42. The surface of the pressing plate 57 contacts the surface of the rectangular plate 53. The surface of the pressing plate 57 contacts the inner wall of the liquid storage box 51. Automatic lubrication of the crushing mechanism 21 is achieved through the extrusion of the pressing plate 57, which reduces the burden on the operator for manual lubrication and helps to extend the service life of the crushing mechanism 21.

[0028] The recycling device includes a receiving housing 61, a filter plate 62, a Z-shaped piece 63, a resisting plate 64, a grip 65 and a limiting plate 66. Move the grip 65 in a direction away from the receiving housing 61. The movement of the grip 65 drives the filter plate 62 to move in a direction away from the receiving housing 61. The surface of the filter plate 62 separates from the surface in contact with the receiving housing 61 during the movement. The receiving housing 61 is fixedly installed at the bottom of the housing 1. The filter plate 62 is clamped on the inner and outer walls of the receiving housing 61. The Z-shaped piece 63 is fixedly installed on the inner wall of the receiving housing 61. The resisting plate 64 is fixedly installed on the surface of the Z-shaped piece 63. The grip 65 is sleeved on the surface of the filter plate 62. The limiting plate 66 is fixedly installed on the surface of the receiving housing 61. The grip 65 is double-limited by the limiting plate 66 to ensure that the operator can only take out the filter plate 62 for maintenance or replacement under the correct operation, effectively improving the safety when replacing the filter plate 62.

[0029] The Z-shaped piece 63 has elasticity. The stretched Z-shaped piece 63 resets under the influence of its own elastic force. The reset of the Z-shaped piece 63 drives the abutting plate 64 to move towards the grip 65. The surface of the abutting plate 64 contacts the surface of the filter plate 62. A fifth spring is arranged between the grip 65 and the filter plate 62. The surface of the grip 65 contacts the surface of the limiting plate 66. Through the elasticity of the Z-shaped piece 63 itself, after the operator releases the limit between the grip 65 and the limiting plate 66, the filter plate 62 can automatically pop out, facilitating the operator to quickly take out the filter plate 62 for maintenance and replacement.

[0030] When this embodiment works, when the vertical slide plate 42 moves downward, it drives the lifting plate 54 to move downward. During the movement of the first gear of the lifting plate 54, it drives the second gear to rotate. The rotation of the second gear drives the rotating column 55 to rotate. The rotation of the rotating column 55 drives the stirring blade 56 to rotate. The rotation of the stirring blade 56 drives the lubricating liquid inside the liquid storage box 51 to move. By stirring the inside of the liquid storage box 51 with the stirring blade 56, the lubricating effect of the lubricating liquid is improved. At the same time that the lifting plate 54 moves downward, it drives the pressing plate 57 to move downward. The pressing plate 57 moves downward to squeeze the lubricating liquid inside the liquid storage box 51. The lubricating liquid squeezed inside the liquid storage box 51 moves towards the inside of the nozzle 52. The continuous downward movement of the pressing plate 57 causes the lubricating liquid inside the nozzle 52 to push open the sealing rubber part and spray towards the output end of the crushing mechanism 21. Automatic lubrication is realized through the extrusion of the pressing plate 57, reducing the lubrication burden of the operator; When replacing the filter plate 62, manually move the grip 65 towards the filter plate 62. The surface of the grip 65 separates from the surface that contacts the limiting plate 66 during the movement, so that the limit of the limiting plate 66 on the grip 65 is released. Then rotate the grip 65 by ninety degrees and move the grip 65 in the direction away from the receiving housing 61. The movement of the grip 65 drives the filter plate 62 to move in the direction away from the receiving housing 61. The surface of the filter plate 62 separates from the surface that contacts the receiving housing 61 during the movement. Through the double limit of the limiting plate 66 on the grip 65, the situation of the operator making wrong operations is effectively reduced. At the same time that the grip 65 and the limiting plate 66 separate, the stretched Z-shaped piece 63 resets under the influence of its own elastic force. The reset of the Z-shaped piece 63 drives the abutting plate 64 to move towards the grip 65. The movement of the abutting plate 64 drives the filter plate 62 to move in the direction away from the receiving housing 61. Through the elasticity of the Z-shaped piece 63 itself, it is convenient for the operator to quickly take out the filter plate 62 for maintenance and replacement.

The scope of the present invention is defined by the appended claims and their equivalents.
