Description

Technical Field

[0001] The utility model relates to the field of fertilizer manufacturing, in particular to a pulverizing device for fertilizer manufacturing. Background Art

[0002] In the process of fertilizer manufacturing, the feces pellets need to be crushed so that the feces pellets meet the size of granulation. In the feces pellets that have been initially crushed, insufficient crushing may occur. The feces pellets are too large to meet the granulation requirements and need to be crushed again. During the crushing and screening process, the screen may be blocked, reducing the efficiency of crushing and screening. Utility Model Content

[0003] In view of the defects in the prior art that the current equipment does not sufficiently crush feces particles, resulting in oversized feces particles and the screen being blocked during screening, a crushing device for fertilizer manufacturing is provided, which can throw feces particles up for crushing and prevent the screen from being blocked.

[0004] A crushing device for fertilizer manufacturing includes a throwing box, a motor is fixedly connected to the outer side of the throwing box, two connecting shafts are rotatably connected inside the throwing box, one of the connecting shafts is fixedly connected to the output shaft of the motor, a pulley is fixedly connected to each of the connecting shafts, a conveyor belt is wound between the two pulleys, a plurality of screens are clamped on the conveyor belt, and a throwing mechanism for throwing up fecal particles is provided on the throwing box.

[0005] Furthermore, the flipping mechanism includes a toothless gear, and both ends of the connecting shaft away from the motor are fixedly connected with the toothless gear, and the two toothless gears are symmetrically arranged. The outer side of the flipping box is rotatably connected to two column gears 1, and the two column gears 1 are symmetrically arranged. The toothless gear is meshed with the column gear 1, and the flipping box is rotatably connected with a mounting shaft, and the mounting shaft passes through the flipping box. A loading plate is fixedly connected to the mounting shaft, and both ends of the mounting shaft are fixedly connected with column gear 2, and the two column gears 2 are symmetrically arranged. The column gear 2 is meshed with the column gear 1, and a torsion spring 1 is connected between the side of the two column gears 2 close to each other and the flipping box, and the two torsion springs 1 are symmetrically arranged, and a crushing net is fixedly connected in the flipping box.

[0006] Furthermore, it also includes a knocking mechanism, which includes a cam, and cams are fixedly connected to both ends of the two connecting shafts. Four fixing frames are fixedly connected to the inner wall of the flip box, and knocking frames are rotatably installed on the four fixing frames. Two torsion springs are connected between the knocking frames and the fixing frames.

[0007] Furthermore, the conveyor belt is provided with a plurality of installation grooves.

[0008] Furthermore, the screen is made of steel wire mesh.

[0009] The beneficial effects of the utility model are as follows: 1. The rotation of column gear 2 will drive the side of the loading plate away from column gear 2 to swing downward. The downward swinging of the loading plate will cause the torsion spring 1 to be twisted. When the toothless gear rotates to the notch, the toothless gear no longer meshes with column gear 1. The torsion spring will reset and drive column gear 2 to rotate in the opposite direction, thereby driving the side of the loading plate away from column gear 2 to swing upward, throwing the larger feces particles on the loading plate onto the crushing net, and being able to crush the incompletely crushed feces particles so that the feces particles meet the granulation standards, thereby improving the quality of the feces particle raw materials.

[0010] 2. The rotation of the connecting shaft will drive the cam to rotate, and the rotation of the cam will squeeze one end of the knocking frame, causing the other end of the knocking frame to swing. The swinging of the knocking frame will cause the torsion spring 2 to twist. When the cam is separated from one end of the knocking frame, the torsion spring 2 will reset and drive the other end of the knocking frame to swing and knock on the screen, so that the feces that may be stuck on the screen will fall off, preventing the screen from being blocked, and improving the efficiency of crushing and screening.

DETAILED DESCRIPTION

[0017] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0018] Embodiment 1: A crushing device for fertilizer production, such as Figure 1-Figure 2 As shown, it includes a throwing box 1, the outer side of the throwing box 1 is fixedly connected to a motor 2, and two connecting shafts 21 are rotatably connected inside the throwing box 1, one of the connecting shafts 21 is fixedly connected to the output shaft of the motor 2, and a pulley 3 is fixedly connected to each of the connecting shafts 21, and a conveying belt 4 is wound between the two pulleys 3. A plurality of screens 5 are clamped on the conveying belt 4, and the screens 5 are used to screen the preliminarily crushed feces particles. The throwing box 1 is provided with a throwing mechanism for throwing up feces particles.

[0019] The flipping mechanism includes a toothless gear 6, and both ends of the connecting shaft 21 away from the motor 2 are fixedly connected with the toothless gear 6, and the two toothless gears 6 are symmetrically arranged. The outer side of the flipping box 1 is rotatably connected with two column gears 7, and the two column gears 7 are symmetrically arranged. The toothless gear 6 is meshed with the column gear 7, and the flipping box 1 is rotatably connected with a mounting shaft 9, and the mounting shaft 9 passes through the flipping box 1. A loading plate 10 is fixedly connected to the mounting shaft 9, and the loading plate 1 0 is used to throw up feces particles, both ends of the installation shaft 9 are fixedly connected with column gears 2 12, the two column gears 2 12 are symmetrically arranged, the column gears 2 12 are meshed with the column gear 1 7, and a torsion spring 11 is connected between the side of the two column gears 2 12 close to each other and the throwing box 1, the two torsion springs 11 are symmetrically arranged, and a crushing net 131 is fixedly connected in the throwing box 1, and the crushing net 131 is used to crush the feces particles discarded by the loading plate 10.

[0020] Initially, the loading plate 10 is locked by meshing the column gear 1 7 and the column gear 2 12. The loading plate 10 is tilted. The staff pours the preliminarily crushed feces particles from the top of the flip box 1. The staff starts the motor 2. The rotation of the output shaft of the motor 2 drives the connecting shaft 21 to rotate. The rotation of the connecting shaft 21 drives one of the pulleys 3 to rotate. The rotation of one of the pulleys 3 drives the other pulley 3 to rotate through the conveyor belt 4, and causes the conveyor belt 4 to rotate. The preliminarily crushed qualified feces particles will fall from the screen 5 when the screen 5 moves, and the larger feces particles will remain on the screen 5 and be transported forward to the loading plate 10. The rotation of the pulley 3 drives the toothed gear 6 to rotate. The rotation of the toothed gear 6 drives the column gear 1 7 to rotate in the opposite direction. The rotation of wheel 1 7 will drive column gear 2 12 to rotate. The direction of rotation of column gear 2 12 is consistent with the direction of rotation of toothless gear 6. The rotation of column gear 2 12 will drive the side of loading plate 10 away from screen 5 to swing downward. The downward swinging of loading plate 10 will cause torsion spring 11 to be twisted. When toothless gear 6 rotates to the gap, toothless gear 6 no longer meshes with column gear 1 7. Torsion spring 11 will reset and drive column gear 2 12 to rotate in the opposite direction, thereby driving the side of loading plate 10 away from screen 5 to swing upward, and throwing larger feces particles on loading plate 10 onto crushing net 131, so that the larger feces particles are crushed. The larger feces particles can be crushed so that the feces particles meet the granulation standards, thereby improving the quality of feces particle raw materials.

[0021] Embodiment 2: Based on embodiment 1, Figure 3-Figure 5 As shown, it also includes a knocking mechanism, which includes a cam 14. Both ends of the two connecting shafts 21 are fixedly connected to the cams 14. The inner wall of the flip box 1 is fixedly connected to four fixing frames 15. The four fixing frames 15 are rotatably mounted with knocking frames 16. The knocking frames 16 will be pushed by the cam 14, so that the knocking frames 16 knock on the screen 5. Two torsion springs 17 are connected between the knocking frames 16 and the fixing frames 15.

[0022] The conveyor belt 4 is provided with a plurality of mounting grooves.

[0023] The material of the screen 5 is a steel wire mesh.

[0024] When the output shaft of the motor 2 drives the connecting shaft 21 to rotate, the rotation of the connecting shaft 21 will drive the cam 14 to rotate, and the rotation of the cam 14 will squeeze one end of the knocking frame 16, so that the other end of the knocking frame 16 swings, and the swinging of the knocking frame 16 will cause the torsion spring 2 17 to twist. When the cam 14 disengages from one end of the knocking frame 16, the torsion spring 2 17 will reset and drive the other end of the knocking frame 16 to swing and knock on the screen 5. The rotation direction of the two cams 14 close to the loading plate 10 is consistent with the rotation direction of the two cams 14 away from the loading plate 10, but the two knocking frames 16 close to the loading plate 10 and the two knocking frames 16 away from the loading plate 10 knock in opposite directions. Through the above operation, feces that may be stuck on the screen 5 can fall off, preventing the screen 5 from being blocked, and the efficiency of crushing and screening can be improved.

[0025] The screen 5 can be removed from the mounting groove on the transmission belt for replacement.
