Description

Technical Field

[0001] This invention relates to the field of fertilizer production technology, and specifically to a cooling device for fertilizer production that prevents fertilizer granules from melting. Background Technology

[0002] Fertilizer production is a category within the fertilizer industry. It is an industrial production sector that uses minerals, water, and air as raw materials to manufacture chemical fertilizers through chemical and mechanical processing. It is an important component of the chemical industry. Most of the products of the fertilizer industry are inorganic fertilizers. The vast majority of fertilizers produced by the fertilizer industry are inorganic compounds, hence fertilizer production belongs to inorganic chemistry. Fertilizer is one of the main means of increasing agricultural output, and many fertilizer products and products closely related to fertilizer production have wide applications in industry.

[0003] In existing technologies, fertilizer production often requires high-temperature treatment. After the fertilizer granules are produced, they need to be cooled. Typically, this cooling process involves feeding piles of fertilizer granules into a cooling device. During this process, the clumps of granules are affected by the concentrated heat, causing some of them to melt and clump together. However, existing fertilizer cooling equipment often uses stirring and tossing during feeding and cooling. In this method, the fertilizer remains clumped during the stirring and cooling process, and gravity causes it to sink and clump together. Consequently, the stirring structure in the cooling device cannot completely break up the clumps of fertilizer granules. Then, during subsequent cooling, the bottom granules cannot be tossed to the top, resulting in uneven cooling and partial surface melting, which affects the particle size and subsequent performance of the fertilizer. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cooling device for fertilizer production that prevents fertilizer granules from melting, thereby solving the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A cooling device for fertilizer production to prevent fertilizer granules from melting includes a distributing tank, a cooling pipe fixedly sleeved on the outer circular wall of the distributing tank, a cooling cylinder fixedly installed on the top surface of the cooling pipe, a feeding cylinder fixedly installed on the top surface of the cooling cylinder, a cover rotatably connected to the top surface of the feeding cylinder, and a feeding pipe fixedly installed on one side of the feeding cylinder.

[0007] A material distribution disc is fixedly sleeved on the inner circular wall of the feed cylinder. A second connecting shaft is rotatably connected inside the material distribution disc. Several dispersing paddles are rotatably connected on the outer circular wall of the second connecting shaft. Several positioning frames are fixedly sleeved on the inner circular wall of the feed cylinder.

[0008] A fixed frame is fixedly sleeved on the inner circular wall of the feed cylinder. A drive shaft is rotatably connected inside the fixed frame. A first connecting shaft is fixedly installed on the bottom surface of the drive shaft. A pusher is fixedly sleeved on the outer circular wall of the first connecting shaft. A mounting cover is fixedly sleeved on the inner circular wall of the cooling cylinder. Several cooling rings are fixedly sleeved on the inner circular wall of the mounting cover. Cooling pipes are fixedly sleeved inside each of the several cooling rings. The cooling pipes penetrate and extend to the outside of the cooling cylinder.

[0009] A mounting shell is fixedly installed on the top surface of the dispensing tray. A mounting frame is movably sleeved inside the mounting shell. Several rubber pressure plates are rotatably connected to the bottom surface of the mounting frame. Every two rubber pressure plates form a group. A return spring is movably sleeved inside the mounting shell. Two positioning posts are fixedly installed on the top surface inside the mounting shell. The positioning posts pass through the mounting frame. A connector is fixedly installed on the bottom surface of the positioning posts. The connector is rotatably connected to the rubber pressure plates.

[0010] By adopting the above technical solution, during use, the operator pours the fertilizer to be cooled into the feed cylinder through the feed pipe or by opening the cover. At this time, the rotation of multiple dispersing paddles breaks up the pile of fertilizer under the action of the dispersing paddles and the positioning frame paddles, thus dispersing large clumps of fertilizer into smaller pieces. These smaller pieces of fertilizer then automatically fall onto the surface of the distribution plate. The rotation of the mounting frame causes it to contact multiple protrusions on the surface of the distribution plate. The rotational force of the mounting frame is converted into an upward moving force due to the influence of the protrusions. This upward movement of the mounting frame compresses the return spring inside the mounting housing. Simultaneously, during the upward movement of the mounting frame, multiple rubber pressure plates, rotatably connected to the bottom of the mounting frame and rotatably connected to the immovable connector, rotate away from each other as the mounting frame moves upward, thus opening the plates. Then, the mounting frame moves away from the distribution plate. When the raised portion of the distributing disc is opened, multiple rubber pressure plates will reset, allowing them to move up and down repeatedly and compress small pieces of fertilizer on the surface of the distributing disc. This disperses the fertilizer particles into granules, which fall through the mesh on the surface of the distributing disc. The falling fertilizer particles will then land on the surface of multiple mounting frames inside the mounting hood. The hot fertilizer particles will then come into contact with the copper mounting frames, and the cooling fluid inside the cooling pipe will continuously exchange heat with the hot fertilizer, thus rapidly cooling the fertilizer on the mounting frame surface and preventing it from melting and clumping again due to high temperature. After the above steps are completed, the operator can rotate the first connecting shaft to drive the pusher to discharge the cooled fertilizer particles from the surfaces of the multiple mounting frames. This achieves the effect of dispersing and cooling the fertilizer particles, preventing them from clumping due to high temperature melting during cooling, which would make them difficult to cool completely.

[0011] Preferably, a first rotating shaft is rotatably connected inside the feed cylinder, a first motor is fixedly installed on the outer circular wall of the feed cylinder, one end of the drive shaft of the first motor is fixedly installed with the first rotating shaft, a driving bevel gear is fixedly sleeved on the outer circular wall of the first rotating shaft, a second driven bevel gear is fixedly installed on the bottom surface of the second connecting shaft, the driving bevel gear and the second driven bevel gear are meshed together, and a first driven bevel gear is fixedly installed on the top surface of the transmission shaft, the first driven bevel gear and the driving bevel gear are meshed together.

[0012] By adopting the above technical solution, the operator uses a first motor, and the rotation of the drive shaft of the first motor will drive the first rotating shaft and the active bevel teeth on its surface to rotate. Then, since the active bevel teeth mesh with the second driven bevel teeth and the first driven bevel teeth respectively, the active bevel teeth will drive the second driven bevel teeth and the first driven bevel teeth to rotate. Then, the second connecting shaft and the transmission shaft will rotate simultaneously. Then, the rotating second connecting shaft will drive multiple dispersing paddles to rotate. At the same time, the rotation of the transmission shaft will drive the first connecting shaft and the pusher frame to rotate, thereby facilitating the rotation of multiple dispersing paddles and the pusher frame.

[0013] Preferably, the dispensing tank is equipped with a filter hopper inside, and two mounting plates are fixedly installed on the top surface of the filter hopper. An adjusting plate is fixedly installed on one side of each mounting plate. A second rotating shaft is rotatably connected inside the dispensing tank, passing through the mounting plates. Two adjusting wheels are fixedly sleeved on the outer circular wall of the second rotating shaft. A second motor is fixedly installed on the outer circular wall of the dispensing tank, and one end of the drive shaft of the second motor is fixedly installed to the second rotating shaft. A third rotating shaft is rotatably connected inside the dispensing tank, and a mounting plate is fixedly installed on the top surface of the third rotating shaft. The device includes a tray with several brush holders fixedly installed on its bottom surface, and several mounting cylinders fixedly installed on the inner circular wall of the dispensing tank. A first connecting column is movably sleeved inside the mounting cylinder, and a first spring is movably sleeved on the outer circular wall of the first connecting column. A limit ring is fixedly sleeved inside the mounting cylinder and movably sleeved with the first connecting column. The top surface of the first connecting column is fixedly installed with the bottom surface of the filter hopper. A third motor is fixedly installed on the bottom surface of the dispensing tank, and the top surface of the drive shaft of the third motor is fixedly installed with the third rotating shaft.

[0014] By adopting the above technical solution, when fertilizer granules are pushed and discharged by the pusher, they fall onto the surface of the filter hopper. At this time, the operator uses a second motor, and the drive shaft of the second motor rotates, which in turn drives the second rotating shaft to rotate. The rotation of the second rotating shaft then drives the adjusting wheel to rotate. At this time, the multiple protrusions on the surface of the adjusting wheel continuously contact the protrusions at the bottom of the adjusting plate, thereby lifting the adjusting plate and causing the filter hopper to move up and down repeatedly. Then, the operator uses a third motor to drive the third rotating shaft, its top mounting plate, and multiple brush holders to rotate. At this time, the plastic brushes at the bottom of the multiple brush holders continuously contact the fertilizer granules at the top of the filter hopper, thereby brushing away the accumulated fertilizer granules and preventing secondary melting and adhesion caused by residual heat. At the same time, the up-and-down reciprocating movement of the filter hopper can prevent the mesh on the surface of the filter hopper from becoming clogged, facilitating the further discharge of fertilizer granules.

[0015] Preferably, two filter media discs are fixedly installed inside the dispensing tank, and two sleeve rods are fixedly sleeved on the outer circular wall of the third rotating shaft. Each sleeve rod corresponds to one of the filter media discs. A movable frame is rotatably connected inside the sleeve rod, a connecting plate is fixedly installed on the bottom surface of the movable frame, a brush plate is fixedly installed on the bottom surface of the connecting plate, a first mounting cap is fixedly installed on the top surface inside the sleeve rod, a second spring is movably sleeved inside the first mounting cap, a second connecting column is slidably connected inside the first mounting cap, and the bottom surface of the second connecting column is rotatably connected to the movable frame.

[0016] By adopting the above technical solution, when the fertilizer granules at the top of the filter hopper are fed, the fertilizer granules will enter the top of the filter disc. At this time, the rotation of the third rotating shaft will drive the two sleeve rods to rotate. Then, the rebound force of the second spring will cause the moving frame at the bottom of the sleeve rod to drive the connecting plate and brush plate to stick to the surface of the filter disc and complete the feeding operation. This allows the pile of fertilizer granules to be fed through the mesh on the surface of the filter disc, while also slowing down the time for the fertilizer granules to fall and discharge, thus providing sufficient time for the fertilizer granules to undergo secondary cooling.

[0017] Preferably, a plurality of positioning tubes are fixedly installed on the inner circular wall of the dispensing tank, the positioning tubes extend to the outside of the dispensing tank, and a nozzle is fixedly sleeved on the inner circular wall of each of the positioning tubes, and the outer circular wall of the cold air pipe is fixedly sleeved with the inner circular wall of the positioning tube.

[0018] By adopting the above technical solution, when the fertilizer granules fall onto the surface of the two filter media discs, the staff connects the external air conditioner to the air pipe through a hose. Then, the cold air is sprayed into the interior of the distribution tank through the air pipe and nozzle, and the fertilizer granules on the surface of the filter media discs are cooled by secondary air cooling. This facilitates the elimination of residual heat inside the fertilizer granules and achieves the effect of completely cooling the fertilizer granules.

[0019] Preferably, the movable frame has two second mounting caps fixedly sleeved inside, a third spring movably sleeved inside the second mounting cap, and a third connecting post slidably connected inside the second mounting cap. The bottom surface of the third connecting post is fixedly installed with the connecting plate.

[0020] By adopting the above technical solution, the gap between the brush plate and the connecting plate and the moving frame can be flexibly adjusted, thereby making it easier to adapt to fertilizer particles of different sizes.

[0021] Preferably, a baffle is fixedly installed on the bottom surface of the dispensing tray.

[0022] By adopting the above technical solution, it is convenient to carry out protective treatment on the second driven bevel tooth, the driving bevel tooth and the first driven bevel tooth, thereby preventing fertilizer particles from entering between their meshing grooves and affecting their use.

[0023] Preferably, two rubber sealing films are fixedly installed on the top and bottom surfaces of the mounting frame, and the rubber sealing films are fixedly installed on the inner wall surface of the mounting shell.

[0024] By adopting the above technical solution, fertilizer particles can be prevented from entering the interior of the casing and affecting its use.

[0025] Preferably, a dispersing paddle is fixedly sleeved on the outer circular wall of the third rotating shaft, and a discharge channel is fixedly installed on the outer circular wall of the distributing tank.

[0026] By adopting the above technical solution, it is easy to discharge the cooled fertilizer granules from the inside of the distribution tank.

[0027] In summary, the present invention has the following main beneficial effects:

[0028] The rotation of multiple dispersing paddles breaks up the pile of fertilizer under the action of the dispersing paddles and positioning frame blades, thus dispersing large clumps of fertilizer into smaller pieces. The rotation of the mounting frame causes it to contact multiple protrusions on the surface of the distribution plate. The upward movement of the mounting frame compresses the return spring inside the mounting shell, and at the same time, multiple rubber pressure plates rotate upward and open. This allows the multiple rubber pressure plates to move up and down repeatedly, compressing the small pieces of fertilizer on the surface of the distribution plate, thereby dispersing them into fertilizer particles that fall through the mesh on the surface of the distribution plate. This achieves the effect of dispersing and cooling the fertilizer particles, preventing the fertilizer from clumping due to high temperature melting during the cooling process, which would make it difficult to cool completely.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 11A cooling device for fertilizer production to prevent fertilizer granules from melting includes: a distribution tank 1, a cooling pipe 2 fixedly sleeved on the outer circular wall of the distribution tank 1, a cooling cylinder 3 fixedly installed on the top surface of the cooling pipe 2, a feeding cylinder 4 fixedly installed on the top surface of the cooling cylinder 3, a cover 6 rotatably connected to the top surface of the feeding cylinder 4, and a feeding pipe 10 fixedly installed on one side of the feeding cylinder 4; a distribution plate 11 fixedly sleeved on the inner circular wall of the feeding cylinder 4, a second connecting shaft 56 rotatably connected inside the distribution plate 11, and several dispersing paddles 15 rotatably connected to the outer circular wall of the second connecting shaft 56; the feeding cylinder 4... The inner circular wall of the feed cylinder 4 is fixedly fitted with several positioning frames 16; the inner circular wall of the feed cylinder 4 is fixedly fitted with a fixing frame 58, the inside of the fixing frame 58 is rotatably connected to a drive shaft 41, the bottom surface of the drive shaft 41 is fixedly installed with a first connecting shaft 21, the outer circular wall of the first connecting shaft 21 is fixedly fitted with a pusher frame 22, the inner circular wall of the cooling cylinder 3 is fixedly fitted with a mounting cover 12, the inner circular wall of the mounting cover 12 is fixedly fitted with several cooling rings 19, and the inside of each of the several cooling rings 19 is fixedly fitted with a cooling pipe 20, which penetrates and extends to the outside of the cooling cylinder 3;A mounting shell 17 is fixedly installed on the top surface of the dispensing tray 11. A mounting frame 19 is movably sleeved inside the mounting shell 17. Several rubber pressure plates 47 are rotatably connected to the bottom surface of the mounting frame 19, with two rubber pressure plates 47 forming a group. A return spring 45 is movably sleeved inside the mounting shell 17. Two positioning posts 49 are fixedly installed on the top surface inside the mounting shell 17, penetrating the mounting frame 19. A connector 50 is fixedly installed on the bottom surface of the positioning posts 49, rotatably connected to the rubber pressure plates 47. In use, the operator pours the fertilizer to be cooled into the inside of the feeding cylinder 4 through the feeding pipe 10 or by opening the cover 6. The rotation of multiple dispersing paddles 15 causes the piled fertilizer to be broken up by the action of the paddles 15 and the positioning frame 16, thus dispersing large clumps of fertilizer into smaller pieces. These smaller pieces then automatically fall onto the surface of the distribution plate 11. The rotation of the mounting frame 19 causes it to contact multiple protrusions on the surface of the distribution plate 11. The rotational force of the mounting frame 19 is converted into an upward moving force due to the influence of the protrusions. This upward movement of the mounting frame 19 compresses the return spring 45 inside the mounting housing 17. Simultaneously, during the upward movement of the mounting frame 19, multiple rubber pressure plates 47, due to their rotational connection to the mounting housing 17, compress the return spring 45. The bottom of the mounting frame 19 is rotatably connected to the immovable connector 50. During the upward movement of the mounting frame 19, multiple rubber pressure plates 47 rotate away from each other, opening upwards. Then, as the mounting frame 19 leaves the protruding portion of the distribution plate 11, the multiple rubber pressure plates 47 return to their original position. This allows the multiple rubber pressure plates 47 to move up and down repeatedly, squeezing small pieces of fertilizer on the surface of the distribution plate 11, dispersing them into fertilizer granules that fall through the mesh on the surface of the distribution plate 11. The falling fertilizer granules then drop into the mounting cover 12, where multiple mounting frames 19 are installed. The hot fertilizer particles come into contact with the copper mounting frame 19, and the cooling fluid inside the cooling pipe 20 continuously exchanges heat with the hot fertilizer, thus rapidly cooling the fertilizer on the surface of the mounting frame 19 and preventing it from melting and clumping again due to high temperature. After the above steps are completed, the operator can rotate the first connecting shaft 21 to drive the pusher 22 to discharge the fertilizer particles that have been cooled on the surface of the mounting frame 19. This achieves the effect of breaking up and cooling the fertilizer particles, preventing them from clumping due to high temperature melting during the cooling process, which would make them difficult to cool completely.

[0046] Example 2

[0047] Based on the above embodiment one, refer to Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 and Figure 12The feed cylinder 4 is rotatably connected to a first rotating shaft 18. A first motor 7 is fixedly installed on the outer circular wall of the feed cylinder 4. One end of the drive shaft of the first motor 7 is fixedly installed to the first rotating shaft 18. A driving bevel gear 43 is fixedly sleeved on the outer circular wall of the first rotating shaft 18. A second driven bevel gear 44 is fixedly installed on the bottom surface of the second connecting shaft 56. The driving bevel gear 43 and the second driven bevel gear 44 are meshed together. A first driven bevel gear 42 is fixedly installed on the top surface of the transmission shaft 41. The first driven bevel gear 42 is meshed with the driving bevel gear 43. When the operator uses the first motor 7, the drive shaft of the first motor 7 rotates, which drives the first rotating shaft 18 and the driving bevel gear 43 on its surface to rotate. Then, because the driving bevel gear 43 is respectively engaged with the second driven bevel gear 44 and the first driven bevel gear 43, the first driven bevel gear 42 is meshed with the driving bevel gear 43. When the driven bevel gear 42 engages, the driving bevel gear 43 drives the second driven bevel gear 44 and the first driven bevel gear 42 to rotate. Consequently, the second connecting shaft 56 and the transmission shaft 41 rotate simultaneously. The rotating second connecting shaft 56 then drives multiple dispersing paddles 15 to rotate. At the same time, the rotation of the transmission shaft 41 drives the first connecting shaft 21 and the pusher frame 22 to rotate, thus facilitating the rotation of multiple dispersing paddles 15 and the pusher frame 22. The inside of the distribution tank 1 is equipped with a filter hopper 13. Two mounting plates 24 are fixedly installed on the top surface of the filter hopper 13. An adjusting plate 51 is fixedly installed on one side of the mounting plate 24. The inside of the distribution tank 1 is rotatably connected to a second rotating shaft 23, which passes through the mounting plate 24. The outer circle of the second rotating shaft 23... Two adjusting wheels 52 are fixedly fitted on the wall. A second motor 8 is fixedly installed on the outer circular wall of the dispensing tank 1. One end of the drive shaft of the second motor 8 is fixedly installed with a second rotating shaft 23. A third rotating shaft 27 is rotatably connected inside the dispensing tank 1. A mounting plate 25 is fixedly installed on the top surface of the third rotating shaft 27. Several brush holders 26 are fixedly installed on the bottom surface of the mounting plate 25. Several mounting cylinders 29 are fixedly installed on the inner circular wall of the dispensing tank 1. A first connecting post 32 is movably fitted inside the mounting cylinder 29. A first spring 33 is movably fitted on the outer circular wall of the first connecting post 32. A limit ring 34 is fixedly fitted inside the mounting cylinder 29. The limit ring 34 is movably fitted with the first connecting post 32. The top surface of the first connecting post 32 is fixedly installed with the bottom surface of the filter hopper 13. A third motor 9 is fixedly installed on the bottom surface of the dispensing tank 1. The top surface of the drive shaft of the third motor 9 is fixedly installed with the third rotating shaft 27. When the fertilizer granules are pushed out by the pusher 22, the fertilizer granules will fall onto the surface of the filter hopper 13. At this time, the operator uses the second motor 8, and the drive shaft of the second motor 8 rotates, which drives the second rotating shaft 23 to rotate. Then, the rotation of the second rotating shaft 23 drives the adjusting wheel 52 to rotate. At this time, the multiple protrusions on the surface of the adjusting wheel 52 will continuously contact the protrusions at the bottom of the adjusting plate 51, and the adjusting plate 51 will be lifted, causing the filter hopper 13 to move up and down repeatedly. Then, the operator uses the third motor 9 to drive the third rotating shaft 27, the mounting plate 25 on its top, and multiple brush holders 26 to rotate.At this time, the plastic brushes at the bottom of the multiple brush holders 26 continuously contact the fertilizer granules at the top of the filter hopper 13, thereby brushing away the accumulated fertilizer granules and preventing secondary melting and adhesion caused by residual heat. Simultaneously, the up-and-down reciprocating movement of the filter hopper 13 prevents clogging of the mesh on its surface, facilitating further feeding of the fertilizer granules.

[0048] Example 3

[0049] Based on the above embodiment one or two, refer to Figure 2 , Figure 3 , Figure 7 and Figure 9 Two filter media discs 14 are fixedly installed inside the distribution tank 1. Two sleeve rods 28 are fixedly sleeved on the outer circular wall of the third rotating shaft 27. Each sleeve rod 28 corresponds to a filter media disc 14. A movable frame 35 is rotatably connected inside the sleeve rod 28. A connecting plate 39 is fixedly installed on the bottom surface of the movable frame 35. A brush plate 40 is fixedly installed on the bottom surface of the connecting plate 39. A first mounting cap 36 is fixedly installed on the top surface inside the sleeve rod 28. A second spring 37 is movably sleeved inside the first mounting cap 36. A second connecting column 38 is slidably connected inside the first mounting cap 36. The bottom surface of the second connecting column 38 is rotatably connected to the movable frame 35. When fertilizer granules are fed from the top of the filter media hopper 13, the fertilizer granules will enter the top of the filter media disc 14. At this time, the rotation of the third rotating shaft 27 will drive the two sleeve rods 28 to rotate. Then, the rebound force of the second spring 37 will cause the movable frame 35 at the bottom of the sleeve rod 28 to drive the connecting plate 39 and the brush plate 40. Plate 40 is attached to the surface of filter media disc 14 and completes the feeding operation, allowing the pile of fertilizer granules to be fed through the mesh on the surface of filter media disc 14. At the same time, it helps to slow down the falling and discharging time of fertilizer granules, allowing sufficient time for secondary cooling of fertilizer granules. Several positioning tubes 30 are fixedly installed on the inner circular wall of the distribution tank 1. The positioning tubes 30 extend to the outside of the distribution tank 1. Spray nozzles 31 are fixedly sleeved on the inner circular wall of the positioning tubes 30. The outer circular wall of the cooling pipe 2 is fixedly sleeved with the inner circular wall of the positioning tubes 30. When fertilizer granules fall to the surface of the two filter media discs 14, the operator connects the external cooling machine to the cooling pipe 2 through the hose. Then, the cold air will be sprayed into the interior of the distribution tank 1 through the cooling pipe 2 and the spray nozzles 31, and perform secondary air cooling on the surface of the filter media disc 14, thereby eliminating the residual heat inside the fertilizer granules and achieving the effect of completely cooling the fertilizer granules.

[0050] Example 4

[0051] Based on the above embodiments one, two, or three, and referring to... Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 9 , Figure 11 and Figure 13 The movable frame 35 has two second mounting caps 53 fixedly sleeved inside. A third spring 54 is movably sleeved inside each second mounting cap 53. A third connecting post 46 is slidably connected inside each second mounting cap 53. The bottom surface of the third connecting post 46 is fixedly installed with the connecting plate 39, allowing for elastic adjustment of the gap between the brush plate 40, the connecting plate 39, and the movable frame 35. This facilitates adaptation to fertilizer particles of different sizes. A baffle 55 is fixedly installed on the bottom surface of the distributing disc 11, facilitating the adjustment of the second driven bevel tooth 44 and the active... The bevel teeth 43 and the first driven bevel teeth 42 are protected to prevent fertilizer particles from entering between their meshing grooves and affecting their use. Two rubber sealing films 48 are fixedly installed on the top and bottom surfaces of the mounting frame 19, respectively. The rubber sealing films 48 are fixedly installed on the inner wall of the mounting shell 17 to prevent fertilizer particles from entering the interior of the mounting shell 17 and affecting its use. A dispersing paddle 15 is fixedly sleeved on the outer circular wall of the third rotating shaft 27. A discharge channel 5 is fixedly installed on the outer circular wall of the distribution tank 1 to facilitate the discharge of cooled fertilizer particles from the interior of the distribution tank 1.

[0052] Working principle: Please refer to Figures 1-13As shown, during use, the operator pours the fertilizer to be cooled into the feed cylinder 4 through the feed pipe 10 or by opening the cover 6. At this time, the rotation of multiple dispersing paddles 15 causes the piled fertilizer to be broken up by the action of the dispersing paddles 15 and the positioning frame 16, thereby dispersing large clumps of fertilizer into smaller pieces. The smaller pieces of fertilizer then automatically fall onto the surface of the distribution plate 11. Then, the rotation of the mounting frame 19 causes the mounting frame 19 to contact multiple protrusions on the surface of the distribution plate 11. At this time, the mounting frame 19 rotates. The force will be converted into an upward moving force due to the influence of the protrusion. As the mounting frame 19 moves upward, it will compress the return spring 45 inside the mounting housing 17. Simultaneously, during the upward movement of the mounting frame 19, multiple rubber pressure plates 47, rotatably connected to the bottom of the mounting frame 19 and rotatably connected to the immovable connector 50, will rotate away from each other as the mounting frame 19 moves upward. Consequently, the multiple rubber pressure plates 47 will rotate upward and open, and then the mounting... When the frame 19 leaves the protruding part on the surface of the distribution plate 11, multiple rubber pressure plates 47 will reset, allowing them to move up and down repeatedly and squeeze the small pieces of fertilizer on the surface of the distribution plate 11, thus dispersing them into fertilizer particles that fall through the mesh on the surface of the distribution plate 11. At this time, the falling fertilizer particles will fall onto the surface of multiple mounting frames 19 inside the mounting cover 12, where the high-temperature fertilizer particles will come into contact with the copper mounting frames 19. Then, the cooling fluid inside the cooling pipe 20 will continuously exchange heat with the high-temperature fertilizer, thereby rapidly cooling the fertilizer on the surface of the mounting frames 19 and preventing it from melting and clumping again due to high temperature. After the above steps are completed, the operator can rotate the first connecting shaft 21 to drive the pusher 22 to discharge the fertilizer particles that have been cooled on the surface of the multiple mounting frames 19. This achieves the effect of dispersing and cooling the fertilizer particles, preventing them from clumping due to high temperature melting during cooling, which would make them difficult to cool completely.
