Technical Field

[0001] This invention relates to the field of crushing equipment technology, and in particular to a high-efficiency corn cob crushing and recycling device for agricultural production. Background Technology

[0002] Corn cob is an agricultural byproduct made from threshed corn kernels. It is characterized by its uniform texture, suitable hardness, good toughness, strong water absorption, and good wear resistance, but it is easily broken during use. Nutritional components of corn cob: Corn cob contains 54.5% sugar, 2.2% crude protein, 0.4% crude fat, 29.7% crude fiber, and 1.2% minerals. When using corn cob as pig feed, it must first be processed and ground into a fine powder.

[0003] For example, patent application number CN201822163806.9 discloses "a corn cob crushing and filtering device", which includes a vertical crushing cylinder, with vertical left and right rotating shafts symmetrically arranged on the left and right sides inside the crushing cylinder. The left and right rotating shafts are rotatably connected to the crushing cylinder, and the top ends of the left and right rotating shafts extend out of the top wall of the crushing cylinder at corresponding positions. A driving component for driving the left and right rotating shafts to rotate is provided above the crushing cylinder.

[0004] However, in the above-mentioned device, the corn cob is crushed by multiple sets of crushing blades at once and then falls from the discharge pipe. This can easily result in incomplete crushing of the corn cob pieces, which affects the crushing quality of the corn cob and its subsequent recycling. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art where corn cobs are crushed by multiple sets of crushing blades at once and fall from the discharge pipe, which easily results in incomplete crushing of corn cob pieces, thus affecting the crushing quality of corn cobs and subsequent recycling. Therefore, this invention proposes a high-efficiency corn cob crushing and recycling device for agricultural production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency corn cob crushing and recycling device for agricultural production includes a crushing box, wherein a reciprocating screw is provided in the middle of the crushing box; It also includes a crushing mechanism for crushing corn cobs in the crushing box.

An electric push rod is fixedly installed on the rear side of the upper end of the push plate and is fixedly connected to the rear end of the crushing box.

[0009] Preferably, an arc rack is fixedly installed at the lower end of the slide bar, a straight rack is engaged at the left end of the arc rack, the upper end of the straight rack is slidably connected to the filter plate, a guide rod two is fixedly installed on the lower side of the left end of the straight rack, and a sliding groove plate is fixedly installed on the lower side of the crushing box corresponding to the guide rod two, and the guide rod two is slidably installed on the sliding groove plate.

[0010] Preferably, a cavity is provided inside the lower side of the reciprocating screw, and a downward-opening nozzle is connected to the cavity on the lower side of the reciprocating screw. An air guide pipe is rotatably connected to the lower end of the reciprocating screw, and a fan is provided on the right side of the crushing box corresponding to the air guide pipe.

[0011] Preferably, a cutting aid plate is symmetrically mounted on the middle part of the filter plate with a reciprocating lead screw, and the two cutting aid plates are fixedly connected by a connecting plate. An electric push rod II is fixedly mounted on the connecting plate, and the upper end of the electric push rod II is fixedly connected to the filter plate.

[0012] Preferably, the upper end of the cutting aid plate is symmetrically fitted with gripping plates on both sides, the gripping plates are arranged in a figure-eight shape, and the ends of the gripping plates that are far apart from each other are fixedly equipped with limiting teeth.

[0013] Preferably, each of the gripping plates is rotatably mounted with a rotating shaft, the lower end of which is fixedly mounted on the cutting aid plate, and a torsion spring is sleeved on the outer side of each rotating shaft.

[0014] Preferably, a top strip is slidably installed through the two gripping plates on the middle part of the cutting aid plate, and the top strip abuts against the gripping plates on both sides.

[0015] Preferably, the cutting aid plate has through grooves on the top strips in the middle, and the ends of the top strips that are far apart from each other are abutted and attached to inclined plates, and the upper ends of the inclined plates are fixedly connected to the filter plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the starting motor drives the reciprocating screw and the crushing rod to rotate, and the corn cob to be crushed is poured into the crushing box. The corn cob is crushed by the rotation of the crushing rod and falls onto the filter plate. The crushed small pieces of corn cob pass through the filter holes on the filter plate and fall into the collection box on the lower side, thus completing the crushing and recycling of corn cob.

[0017] 2. In this invention, when the reciprocating screw rotates, it also drives the filter plate to slide up and down on the inner wall of the crushing box. This helps to lift the incompletely crushed corn cob pieces that have fallen onto the filter plate and allow them to contact the crushing rod on the lower side for further crushing. This facilitates the complete crushing of the corn cobs in the crushing box, preventing a large accumulation of incompletely crushed corn cob pieces on the filter plate. It eliminates the need for regular manual cleaning of the filter plate and prevents clogging, thereby improving the crushing efficiency and quality of the corn cobs. At the same time, when the corn cob pieces on the filter plate are crushed by the rotation of the crushing rod on the lower side, it also facilitates the stirring of the corn cobs on the filter plate, which helps the crushed corn cob pieces to quickly pass through the filter holes on the filter plate.

[0018] 3. In this invention, when the filter plate moves the corn cob blocks upwards synchronously, the corn cob blocks will rise into the collecting grinding plate. The electric push rod is activated to drive the push plate forward until the push plate and the collecting grinding plate cooperate to squeeze the corn cob blocks in the collecting grinding plate. This makes it easier to crush the corn cob blocks that are not completely crushed, which is beneficial for the subsequent crushing rod to crush the corn cob blocks, thus improving the crushing quality and efficiency.

[0019] 4. In this invention, when the reciprocating screw rotates, it also drives the active impact bar to rotate. The active impact bar will intermittently strike the passive impact bar, causing the passive impact bar to drive the collecting grinding plate and guide rod to slide outward on the crushing box, stretching the spring. At this time, the collecting grinding plate and the push plate will crush the corn cob between them, thereby improving the crushing quality of the corn cob.

[0020] 5. In this invention, when the filter plate reciprocates up and down, it also drives the straight rack and guide rod two to move up and down synchronously. The guide rod two slides along the S-shaped trajectory of the slide plate, thereby driving the straight rack to reciprocate back and forth on the lower side of the filter plate. The straight rack drives the arc rack to rotate, and the arc rack drives the slide rod, ring plate and cutter to rotate synchronously along the arc groove. The cutter is designed to cut the corn cob fragments or corn cob skin that are blocked at the connection between the reciprocating screw and the filter plate, effectively preventing the corn cob fragments or corn cob skin from further entering and causing blockage at the connection between the reciprocating screw and the filter plate. This ensures the normal and smooth threaded connection between the filter plate and the reciprocating screw, avoids jamming of the corn cob crushing device, and improves work efficiency.

[0021] 6. In this invention, when the cutter reciprocates to cut the corn cob pieces or corn cob skin at the connection between the reciprocating screw and the filter plate, the electric push rod 2 pushes the auxiliary cutting plate to rise to the upper part of the filter plate. The auxiliary cutting plate facilitates the concentration of corn cob fragments or corn cob skin around the connection between the reciprocating screw and the filter plate, which is beneficial for the cutter's circumferential cutting and improves the cutting efficiency and quality of the cutter.

[0022] 7. In this invention, when the cutting aid plate rises, it also drives the top bar and the gripper plate to rise synchronously. The top bar slides upward on the inclined plate until its lower end contacts the inclined surface of the inclined plate. At this time, the torsion spring drives the gripper plate to rotate on the rotating shaft in the direction of the reciprocating screw. The gripper plate pushes the top bar to slide outward along the inclined surface of the inclined plate in the through groove. The gripper plate and the limiting teeth make it easy to firmly grip the corn cob skin at the connection between the reciprocating screw and the filter plate and adhere it to the surface of the reciprocating screw. This makes it easier for the cutter to cut the blocked corn cob skin at the connection between the reciprocating screw and the filter plate, reducing the corn cob skin from blocking the connection between the reciprocating screw and the filter plate, and improving the crushing quality and efficiency of the corn cob.

[0026] Reference Figures 1-16 A high-efficiency corn cob crushing and recycling device for agricultural production includes a crushing box 1, with a reciprocating screw 2 located in the center of the crushing box 1; and a crushing mechanism for crushing the corn cobs in the crushing box 1. The crushing mechanism includes a motor 3 located at the upper end of the reciprocating screw 2, which is fixedly connected to the upper end of the crushing box 1. Crushing rods 4 are fixedly installed at equal intervals on the outer side of the reciprocating screw 2. A filter plate 5 is threadedly installed on the lower side of the reciprocating screw 2, with both ends of the filter plate 5 slidably connected to the inner wall of the crushing box 1. A collection device is located inside the crushing box 1 between the two lower crushing rods 4. A grinding plate 6 is collected and a guide rod 7 is fixedly installed on the left end of the grinding plate 6. The left end of the guide rod 7 is slidably installed on the crushing box 1. A spring 8 is sleeved on the outer side of the guide rod 7. The left and right ends of the spring 8 are fixedly connected to the guide rod 7 and the crushing box 1, respectively. A passive impact bar 601 is fixedly installed at the front end of the collecting grinding plate 6. An active impact bar 602 is fixedly installed on the outer side of the reciprocating screw 2 corresponding to the passive impact bar 601. A push plate 9 is slidably installed on the rear side of the crushing box 1 corresponding to the collecting grinding plate 6. An electric push rod 10 is fixedly installed on the rear side of the upper end of the push plate 9. The electric push rod 10 is fixedly connected to the rear end of the crushing box 1. During operation, the starter motor 3 drives the reciprocating screw 2 and the crushing rod 4 to rotate, pouring the corn cobs to be crushed into the crushing box 1. The corn cobs are crushed by the rotation of the crushing rod 4 and fall onto the filter plate 5. The small pieces of crushed corn cobs pass through the filter holes on the filter plate 5 and fall into the collection box below, completing the crushing and recycling of the corn cobs. When the reciprocating screw 2 rotates, it also drives the filter plate 5 to slide up and down on the inner wall of the crushing box 1, which helps to lift the incompletely crushed corn cob pieces that fall onto the filter plate 5 and contact the crushing rod 4 below for further crushing. This ensures that the corn cobs in the crushing box 1 are completely crushed, preventing a large accumulation of incompletely crushed corn cob pieces on the filter plate 5. This eliminates the need for regular manual cleaning of the filter plate 5 and prevents clogging, thus improving the crushing efficiency and quality of the corn cobs. Simultaneously, when the corn cob pieces on the filter plate 5 are crushed by the rotation of the crushing rod 4 below, they also... The agitation of the corn cobs on the filter plate 5 helps the crushed corn cob pieces to quickly pass through the filter holes on the filter plate 5. When the filter plate 5 moves the corn cob pieces upward synchronously, the corn cob pieces will rise into the collecting grinding plate 6. The electric push rod 10 is activated to drive the push plate 9 forward until the push plate 9 cooperates with the collecting grinding plate 6 to squeeze the corn cob pieces in the collecting grinding plate 6. This makes it easier to crush the corn cob pieces that are not completely crushed, which is beneficial for the subsequent crushing rod 4 to crush the corn cob pieces, improving the crushing quality and efficiency. When the reciprocating screw 2 rotates, it will also drive the active impact bar 602 to rotate. The active impact bar 602 will intermittently hit the passive impact bar 601, causing the passive impact bar 601 to drive the collecting grinding plate 6 and the guide rod 7 to slide outward on the crushing box 1, stretching the spring 8. At this time, the collecting grinding plate 6 and the push plate 9 will crush the corn cob between them, thereby improving the crushing quality of the corn cob.

[0027] As an embodiment of the present invention, an anti-clogging mechanism is also provided to prevent blockage at the connection between the reciprocating lead screw 2 and the filter plate 5. The anti-clogging mechanism includes a ring plate 11 that is abutting and fitted at the middle of the upper end of the filter plate 5. Cutters 12 are symmetrically fixedly installed on the left and right sides of the inner side of the ring plate 11. The cutters 12 are in contact with the surface of the reciprocating lead screw 2. A slide rod 13 is fixedly installed on the lower left side of the ring plate 11. An arc-shaped groove 14 is opened on the middle of the filter plate 5 corresponding to the slide rod 13. The slide rod 13 is slidably installed on the filter plate 5. The lower end of the slide rod 13 is fixedly fixed. An arc-shaped rack 15 is fixedly installed, with a straight rack 16 meshing at its left end. The upper end of the straight rack 16 is slidably connected to the filter plate 5. A guide rod 17 is fixedly installed on the lower side of the left end of the straight rack 16. A sliding groove plate 18 is fixedly installed on the lower side of the crushing box 1, corresponding to the guide rod 17. The guide rod 17 is slidably installed on the sliding groove plate 18. A cavity is opened inside the lower side of the reciprocating screw 2. A downward-opening nozzle 19 is connected to the cavity on the lower side of the reciprocating screw 2. An air guide pipe 20 is rotatably connected to the lower end of the reciprocating screw 2. A fan 21 is installed on the right side of the box 1, corresponding to the air duct 20. A cutting aid plate 22 is symmetrically mounted on the middle of the filter plate 5, slidingly through a reciprocating screw 2. The two cutting aid plates 22 are fixedly connected by a connecting plate, on which an electric actuator 221 is fixedly mounted. The upper end of the electric actuator 221 is fixedly connected to the filter plate 5. A gripping plate 23 is symmetrically abutted against and fitted on the upper end of each cutting aid plate 22. The gripping plates 23 are arranged in a "V" shape, and each gripping plate 23 has a limiting tooth 24 fixedly mounted on its opposite ends. A rotating shaft 25 is rotatably mounted through each plate 23. The lower end of the rotating shaft 25 is fixedly mounted on the cutting aid plate 22. A torsion spring 26 is sleeved on the outer side of each rotating shaft 25. A top strip 27 is slidably mounted through each of the two gripping plates 23 in the middle of the cutting aid plate 22. The top strip 27 abuts against the gripping plates 23 on both sides. A through groove 28 is opened in the middle of the cutting aid plate 22 corresponding to the top strip 27. An inclined plate 29 is abutted and attached to the opposite end of the top strip 27. The upper end of the inclined plate 29 is fixedly connected to the filter plate 5. During operation, when the filter plate 5 reciprocates up and down, it also drives the rack 16 and guide rod 17 to move up and down synchronously. The guide rod 17 slides along the S-shaped trajectory of the slide plate 18, which in turn drives the rack 16 to reciprocate back and forth on the lower side of the filter plate 5. The rack 16 drives the arc rack 15 to rotate, and the arc rack 15 drives the slide rod 13, the ring plate 11, and the cutter 12 to rotate synchronously along the arc groove 14. The cutter 12 is designed to easily remove corn cob fragments or corn cob debris that are blocked at the connection between the reciprocating screw 2 and the filter plate 5. The cutting blade 12 effectively prevents corn cob fragments or outer skin from further entering and causing blockage at the connection between the reciprocating screw 2 and the filter plate 5. This ensures the normal and smooth threaded connection between the filter plate 5 and the reciprocating screw 2, avoiding jamming of the corn cob crushing device and thus improving work efficiency. When the cutter 12 reciprocates to cut the corn cob pieces or outer skin at the connection between the reciprocating screw 2 and the filter plate 5, the electric push rod 221 pushes the auxiliary cutting plate 22 to rise to the upper side of the filter plate 5. The cutting plate 22 facilitates the collection of corn cob fragments or corn cob husks surrounding the connection between the reciprocating screw 2 and the filter plate 5, which is beneficial for the circumferential cutting of the cutter 12 and improves the cutting efficiency and quality of the cutter 12. At the same time, when the auxiliary cutting plate 22 rises, it also drives the top bar 27 and the gripper plate 23 to rise synchronously. The top bar 27 slides upward on the inclined plate 29 until the lower end of the top bar 27 contacts the inclined surface of the inclined plate 29. Then, the torsion spring 26 drives the gripper plate 23 to move towards the reciprocating screw 2 on the rotating shaft 25. When the screw rotates, the gripper 23 pushes the top bar 27 to slide outward along the inclined surface of the inclined plate 29 in the through groove 28. The gripper 23 and the limiting teeth 24 make it easy to grip the corn cob skin at the connection between the reciprocating screw 2 and the filter plate 5 and adhere it to the surface of the reciprocating screw 2. This makes it easier for the cutter 12 to cut the blocked corn cob skin at the connection between the reciprocating screw 2 and the filter plate 5, reducing the amount of corn cob skin blocking the connection between the reciprocating screw 2 and the filter plate 5, and improving the crushing quality and efficiency of the corn cob.

[0028] Working principle: In use, the starting motor 3 drives the reciprocating screw 2 and the crushing rod 4 to rotate. The corn cobs to be crushed are poured into the crushing box 1. The corn cobs are crushed by the rotation of the crushing rod 4 and fall onto the filter plate 5. The small pieces of crushed corn cobs pass through the filter holes on the filter plate 5 and fall into the collection box on the lower side, completing the crushing and recycling of corn cobs. When the reciprocating screw 2 rotates, it also drives the filter plate 5 to slide up and down on the inner wall of the crushing box 1. This helps to lift the incompletely crushed corn cob pieces that fall onto the filter plate 5 and contact the crushing rod 4 on the lower side for further crushing. This ensures that the corn cobs in the crushing box 1 are completely crushed, avoiding a large accumulation of incompletely crushed corn cob pieces on the filter plate 5. It eliminates the need for manual cleaning of the filter plate 5 at regular intervals and prevents clogging of the filter plate 5. The filter plate 5 is plugged, which improves the crushing efficiency and quality of the corn cob. Simultaneously, when the corn cob pieces on the filter plate 5 are crushed by the rotation of the lower crushing rod 4, it also facilitates the agitation of the corn cob pieces on the filter plate 5, helping the crushed corn cob pieces to quickly pass through the filter holes on the filter plate 5. When the filter plate 5 drives the corn cob pieces to rise synchronously, the corn cob pieces will rise into the collecting grinding plate 6. The electric push rod 10 is then activated, driving the push plate 9 forward until the push plate 9 cooperates with the collecting grinding plate 6 to squeeze the corn cob pieces in the collecting grinding plate 6. This facilitates the crushing of incompletely crushed corn cob pieces, which is beneficial for the subsequent crushing work of the crushing rod 4, improving the crushing quality and efficiency. Furthermore, when the reciprocating screw 2 rotates, it also drives the active impact bar 602 to rotate, and the active impact bar 602 will intermittently... The intermittent impact of the passive impact bar 601 causes the passive impact bar 601 to drive the collecting grinding plate 6 and the guide rod 1 7 to slide outward on the crushing box 1, stretching the spring 8. At this time, the collecting grinding plate 6 and the push plate 9 will crush the corn cobs between them, thereby improving the crushing quality of the corn cobs. When the filter plate 5 moves up and down, it will also drive the straight toothed rack 16 and the guide rod 2 17 to move up and down synchronously. The guide rod 2 17 slides along the S-shaped trajectory of the slide plate 18, thereby driving the straight toothed rack 16 to move back and forth on the lower side of the filter plate 5. The straight toothed rack 16 drives the arc toothed rack 15 to rotate. The arc toothed rack 15 drives the slide rod 13, the ring plate 11 and the cutter 12 to rotate synchronously along the arc groove 14. The cutter 12 is designed to easily remove corn cob fragments or corn cobs that are blocked at the connection between the reciprocating screw 2 and the filter plate 5. The outer skin is cut, effectively preventing corn cob fragments or outer skin from further entering and causing blockage at the connection between the reciprocating screw 2 and the filter plate 5. This ensures the normal and smooth threaded connection between the filter plate 5 and the reciprocating screw 2, avoiding jamming of the corn cob crushing device and thus improving work efficiency. When the cutter 12 reciprocates to cut the corn cob pieces or outer skin at the connection between the reciprocating screw 2 and the filter plate 5, the electric push rod 221 pushes the auxiliary cutting plate 22 to rise to the upper side of the filter plate 5. The auxiliary cutting plate 22 facilitates the concentration of corn cob fragments or outer skin around the connection between the reciprocating screw 2 and the filter plate 5, which is beneficial for the cutter 12 to perform circumferential cutting, improving the cutting efficiency and quality of the cutter 12. At the same time, when the auxiliary cutting plate 22 rises...This also causes the top bar 27 and the gripper plate 23 to rise synchronously. The top bar 27 slides upward on the inclined plate 29 until its lower end contacts the inclined surface of the inclined plate 29. At this point, the torsion spring 26 drives the gripper plate 23 to rotate on the rotating shaft 25 towards the reciprocating screw 2. The gripper plate 23 then pushes the top bar 27 to slide outward along the inclined surface of the inclined plate 29 within the through groove 28. The gripper plate 23 and the limiting teeth 24 effectively grip the corn cob husk at the connection between the reciprocating screw 2 and the filter plate 5, ensuring it adheres to the surface of the reciprocating screw 2. This facilitates the cutter 12's cutting of the blocked corn cob husk at the connection between the reciprocating screw 2 and the filter plate 5, reducing corn cob husk blockage and improving the crushing quality and efficiency of the corn cob.
