[0002] Organic fertilizers are mainly derived from plants and (or) animals. They are carbon-containing materials that are applied to the soil to provide plant nutrition. They are processed from biological materials, animal and plant waste, and plant residues, eliminating toxic and harmful substances, and are rich in beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. They can not only provide comprehensive nutrition for crops, but also have a long fertilizer effect, increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of the soil.

A one-way valve is provided in the first air guide pipe 36 and the second air guide pipe 37, and one end of the first air guide pipe 36 and the second air guide pipe 37 that are connected to the drying pipe 16 are both located on the side of the sliding plug 17 away from the long rod 18, and one end of the second air guide pipe 37 away from the drying pipe 16 is connected to the heating box 5, and a blowing box 34 located between the bottom plate 19 and the first material guide plate 31 is fixedly installed between the inner walls of both sides of the box body 1, and the blowing box 34 is located on the side of the baffle 14 close to the first material guide plate 31, and one end of the first air guide pipe 36 away from the drying pipe 16 is connected to the blowing box 34;

[0030] The box body 1 is provided with a feeding mechanism connected with the extrusion mechanism, and the feeding mechanism includes a circular tube 15 fixedly installed between the inner walls on both sides of the box body 1, the circular tube 15 is fixedly installed at the bottom of the baffle 14 and the first guide plate 31, and the top and bottom of the circular tube 15 are provided with entry slots 40, and the upper entry slot 40 is located between the baffle 14 and the first guide plate 31. A first rotating shaft 9 is rotatably connected between the inner walls on both sides of the box body 1, and a round roller 38 slidably connected to the inner wall of the circular tube 15 is fixedly installed on the outer wall of the first rotating shaft 9. Four evenly arranged feeding slots 39 are provided on the outer wall of the round roller 38, and the entry slots 40 and the feeding slots 39 are adapted to each other. One end of the first rotating shaft 9 passes through a side wall of the box body 1 and extends out, and a gear 10 is installed at one end of the first rotating shaft 9 outside the box body 1 through a one-way bearing. A rack 8 is fixedly installed on the connecting rod 6 on a side wall outside the box body 1, and the rack 8 is meshed with the gear 10.

[0031] When the present invention is used, the servo motor 13 is started and the fermented fertilizer is introduced into the feeding port 4. The servo motor 13 causes the second rotating shaft 23 to rotate clockwise and counterclockwise intermittently. When the second rotating shaft 23 rotates clockwise, the third rotating shaft 24 is rotated by setting the second transmission assembly 32. By setting the crushing roller 21, the introduced fertilizer can be crushed. After crushing, the fertilizer is guided by the second guide plate 33 to fall onto the bottom plate 19 and is located between the extrusion plate 27 and the third partition plate 28. By setting the first transmission assembly 12, the third rotating shaft 24 is rotated. The threaded rod 22 is driven to rotate in one direction, so that the extrusion plate 27 moves toward the direction close to the third partition plate 28. When the extrusion plate 27 moves, the auxiliary plate 35 prevents the crushed fertilizer from falling between the extrusion plate 27 and the first partition plate 11. The extrusion plate 27 squeezes the crushed fertilizer out of the opening 26. The rotation of the threaded rod 22 drives the blade 29 to rotate, so that the extruded fertilizer is cut into particles. The granular fertilizer slides along the surface of the first guide plate 31 and falls into one of the guide grooves 39 adapted to the inlet slot 40 through the upper inlet slot 40.

[0032] During the movement of the extrusion plate 27 toward the third partition plate 28, the connecting block 30 and the connecting rod 6 are provided to make the long rod 18 and the sliding plug 17 move away from the first partition plate 11, thereby generating an extrusion effect, and the hot air in the drying tube 16 is squeezed into the blowing box 34 through the first air guide tube 36 and blown out through the nozzle on the blowing box 34. The blown hot air can dry the fertilizer on the first guide plate 31. At the same time, the connecting rod 6 makes the rack 8 move away from the first partition plate 11, and the gear 10 is rotated in one direction through the meshing connection between the rack 8 and the gear 10. Since the gear 10 and the first rotating shaft 9 are installed and connected through a one-way bearing, and the inner and outer rings of the one-way bearing are idling and cannot be transmitted at this time, the first rotating shaft 9 cannot rotate at this time, that is, the round roller 38 does not rotate;

[0033] When the extrusion plate 27 moves to the point where the extrusion plate 27 is close to the third partition plate 28, the servo motor 13 causes the second shaft 23 to rotate counterclockwise, and by setting the second transmission assembly 32, the third shaft 24 and the first transmission assembly 12, the threaded rod 22 is rotated in the other direction, so that the extrusion plate 27 moves toward the first partition plate 11 and returns to the initial position. During this process, the crushed material that falls to the top of the auxiliary plate 35 will be pushed between the extrusion plate 27 and the third partition plate 28 through the limit of the second guide plate 33. By setting the connecting block 30 and the connecting rod 6, the long rod 18 and the sliding plug 17 are moved toward the first partition plate 11, thereby generating a suction effect, and the heated gas in the heating box 5 is sucked into the drying tube 16 through the second air guide pipe 37 for the next After heating once, the connecting rod 6 moves the rack 8 toward the first partition plate 11, so that the gear 10 rotates in the other direction. At this time, the inner and outer rings of the one-way bearing are locked and can transmit the power, so that the first rotating shaft 9 rotates. When the rack 8 returns to the initial position, the first rotating shaft 9 rotates ninety degrees. The rotation of the first rotating shaft 9 drives the round roller 38 to rotate, so that the round roller 38 rotates, so that one of the feed troughs 39 containing the dried granular fertilizer rotates ninety degrees, and the other feed trough 39 on the round roller 38 rotates to match the upper inlet slot 40, and so on. When one of the feed troughs 39 containing the dried granules matches the lower inlet slot 40, the dry granular fertilizer in the feed trough 39 can fall out through the lower inlet slot 40 for transportation or bagging.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
