[0002] In the production process of compound fertilizer, the various components need to be mixed in proportion to form a slurry to obtain compound fertilizer raw materials, and then the compound fertilizer raw materials are granulated and dried to form granular fertilizer.

[0003] There are many qualities of compound fertilizers, but the effective period of compound fertilizers is very short, generally 50-60 days, due to the restrictions of nitrogen fertilizers, phosphorus fertilizers and potassium fertilizers, which cannot meet the nutrient needs of crops throughout the entire growth period. This not only reduces the overall fertilizer application effect, but also increases the input cost of farmers, increases the burden on farmers, and limits farmers' enthusiasm for using compound fertilizers. At present, the proportion of compound fertilizers with a ratio of 15:15:15 is the largest. This nutrient ratio is only suitable for base fertilizer application and is difficult to apply in the growth stages of crops in late winter and early spring. Therefore, different types of compound fertilizers are deployed according to the different growth processes of crops.

[0004] In view of the above-mentioned related technologies, it is required to simplify the fertilization procedure in agricultural production. It is difficult to adapt to the production needs by constantly adjusting the formula of compound fertilizers. Summary of the invention

[0007] In this embodiment, the preferred potassium chloride is 33 parts, monoammonium phosphate is 29 parts, potassium ammonium sulfate is 36 parts, magnesium sulfate is 5 parts and potassium sulfate is 8 parts. Potassium chloride is used to supplement potassium to crops, monoammonium phosphate is used to supplement phosphorus and ammonium to crops, potassium ammonium sulfate is used to supplement sulfur and ammonium to crops, magnesium sulfate is used to supplement sulfur and magnesium to crops, and potassium sulfate is used to supplement sulfur to crops. Sulfur is used to promote protein synthesis, enzyme activity and the generation of certain secondary metabolites.

[0008] In other embodiments, the ratio of potassium chloride, monoammonium phosphate, potassium ammonium sulfate, magnesium sulfate and potassium sulfate can be adaptively adjusted according to the soil conditions, for example, 30 parts of potassium chloride, 25 parts of monoammonium phosphate, 33 parts of potassium ammonium sulfate, 3 parts of magnesium sulfate and 5 parts of potassium sulfate, or for example, 35 parts of potassium chloride, 33 parts of monoammonium phosphate, 38 parts of potassium ammonium sulfate, 8 parts of magnesium sulfate and 15 parts of potassium sulfate.

[0009] The compound fertilizer ratio in this embodiment provides sulfur nutrition to plants, promotes crop growth and improves crop quality, increases crop resistance to cold and drought, and enables smooth growth in late winter and early spring, making the compound fertilizer suitable for more crops and different stages of crop growth, thereby simplifying the fertilization procedure.

[0012] After the materials in the mixing chamber are mixed, the mixing chamber is connected to the extrusion chamber so that the mixed materials in the mixing chamber fall between the two extrusion rollers. The extrusion drive member drives the extrusion rollers to rotate so that the materials between the extrusion rollers are extruded and formed in the molding groove.

[0013] The extruded material falls into the separation chamber, and the transmission assembly drives the separation rod to rotate synchronously when the extrusion roller rotates, so that the separation rod breaks up the agglomerated finished products, so that the finished products separated by particles are discharged from the screening bucket, and the remaining material blocks are screened out from the screening hole.

[0015] Optionally, a recovery slope is provided below the screening hopper, the recovery slope extends into the feed box, and one end of the feed box where the recovery slope is located is lower than another end below the screening hopper.

[0016] By adopting the above technical solution, the setting of the recovery slope recovers the remaining material blocks into the feed box, so that they can be reused in the next granulation process.

[0017] Optionally, a rotating seat is fixedly connected to the output shaft of the mixing drive component, and the stirring rod is fixedly connected to the rotating seat.

When the rotating seat rotates, the stirring rod and the crushing element are driven to rotate synchronously around the axis of the rotating seat. The stirring rod and the crushing element rotate synchronously in the mixing chamber, so that the crushing element can break up the material blocks remaining in the mixing chamber into materials again, thereby avoiding the problem of difficult molding caused by the material blocks in the subsequent extrusion granulation process. At the same time, the stirring rod is used to fully mix the recycled material and the newly added material, so that the material ratio of the finished product is more uniform.

The crushing rod is vertically rotatably connected to the rotating seat, the crushing leaves are fixedly connected to the end of the crushing rod away from the bottom of the granulation box, and the synchronous element is used to connect the stirring rod and the crushing rod so that the crushing rod is driven to rotate around its own axis when the stirring rod rotates.

[0020] By adopting the above technical solution, when the stirring rod rotates around the axis of the rotating seat, the stirring rod drives the crushing rod to rotate around its own axis through the synchronous member, thereby driving the crushing blades to rotate and re-crush the material blocks squeezed in the mixing chamber into materials, thereby improving the compactness of the particles during the granulation process.

[0022] By adopting the above technical solution, when the stirring rod rotates around the axis of the rotating seat, the stirring rod drives the fixed plate and the rotating gear ring to rotate synchronously around the axis of the rotating seat. At this time, the fixed gear ring drives the meshing rotating gear ring to rotate, and the rotation of the rotating gear ring drives the crushing gear to rotate rapidly. The rapid rotation of the crushing gear drives the crushing rod and the crushing leaves to rotate rapidly, thereby crushing the material blocks into materials again.

[0023] Optionally, a cleaning rod is arranged between the squeezing roller and the separation rod, and a plurality of cleaning brushes are fixedly connected to the cleaning rod. The cleaning brushes abut against the surface of the squeezing roller. The cleaning rod is connected to the transmission assembly, and the rotation direction of the cleaning rod is opposite to the rotation direction of the squeezing roller.

[0024] By adopting the above technical solution, the cleaning rod is used to further clean the residual materials on the surface of the extrusion roller, so that the surface of the cleaning rod is cleaner, which is convenient for the next extrusion granulation of the extrusion roller.

[0026] By adopting the above technical solution, the hybrid drive member is used to drive the active toothed disc and the extrusion roller to rotate synchronously, and the active toothed disc drives the driven toothed disc to rotate, so that the sides of the two extrusion rollers that are in contact with each other are synchronously extruded and rotated downward to complete the extrusion of the material.

[0027] The rotation of the squeezing roller drives the cleaning rod to rotate using a transmission belt. The rotation direction of the cleaning rod is the same as that of the squeezing roller. Therefore, the moving directions of the cleaning brush and the squeezing roller are opposite, so that the cleaning brush can smoothly clean the residue on the squeezing roller.

[0028] When the cleaning rod rotates, the driving gear, the main transmission gear, the slave transmission gear and the driven gear are used to drive the separation rod to rotate, so that the sides of the separation rods close to each other rotate upward, thereby separating the materials squeezed by the squeezing roller, so that the finished products are clearly separated.

[0029] Through the transmission of the driving toothed disc, the driven toothed disc, the transmission belt, the driving gear, the main transmission gear, the driven transmission gear and the driven gear, the coordinated movement of the rod extrusion roller, the cleaning rod and the separation rod can be synchronously driven by the power source of one extrusion driving member.

[0030] Optionally, the conveying member includes an active roller, a driven roller, a conveying motor, a conveyor belt and a partition plate. The feed box extends to the mixing chamber.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-7This application is described in further detail.

[0046] The embodiment of the present application discloses a compound fertilizer.

[0047] A compound fertilizer comprises the following raw materials in parts by weight: 30-35 parts of potassium chloride, 25-33 parts of monoammonium phosphate, 33-38 parts of potassium ammonium sulfate, 3-8 parts of magnesium sulfate and 5-15 parts of potassium sulfate.

[0048] By adopting the above technical solution, potassium chloride is used to supplement potassium elements for crops, monoammonium phosphate is used to supplement phosphorus and ammonium elements for crops, potassium ammonium sulfate is used to supplement sulfur elements and ammonium elements for crops, magnesium sulfate is used to supplement sulfur elements and magnesium elements for crops, and potassium sulfate is used to supplement sulfur elements for crops. Sulfur elements are used to promote protein synthesis, enzyme activity and the generation of certain secondary metabolites. By supplying plants with sulfur nutrition, crop growth and crop quality are promoted, and crop resistance and drought resistance are increased. Crops can grow smoothly in late winter and early spring, so that compound fertilizers can be adapted to more crops and different stages of crop growth, thereby simplifying the fertilization procedure.

[0049] The embodiment of the present application also discloses a compound fertilizer granulation device, including.

[0050] Reference Figure 1-3 A compound fertilizer granulation equipment comprises a granulation box 1, a feeding assembly 2, a mixing assembly 3, an extrusion assembly 4, a separation assembly 5, a transmission assembly 6 and a discharging assembly 7. The granulation box 1 is provided with a mixing chamber 11, an extrusion chamber 12 and a separation chamber 13 from top to bottom, wherein the mixing assembly 3 is installed in the mixing chamber 11, the extrusion assembly 4 is installed in the extrusion chamber 12, and the separation assembly 5 is installed in the separation chamber 13. The feeding assembly 2 is installed on one side of the granulation box 1, and the top of the feeding assembly 2 extends into the mixing chamber 11, so as to transport the material into the mixing chamber 11. The transmission assembly 6 is installed between the extrusion assembly 4 and the separation assembly 5, so that when the extrusion assembly 4 moves, it can synchronously drive the separation assembly 5 to move. The discharging component 7 is a screening hopper 71 installed below the separation component 5. A plurality of screening holes 72 are provided on the screening hopper 71. One end of the screening hopper 71 is fixedly connected to the granulation box 1, and the other end passes through the granulation box 1. The screening hopper 71 is tilted, and the end passing through the granulation box 1 is tilted downward, so that the screening hopper 71 discharges distinct compound fertilizer particles.

[0051] The feed assembly 2 includes a feed box 21 and a conveying member 22. The feed box 21 is installed on one side of the granulation box 1. A feed port 23 is provided on the upper side of the feed box 21. One end of the conveying member 22 is connected to the feed box 21, and the other end is connected to the mixing chamber 11.

[0052] In this embodiment, the conveying member 22 includes an active roller 221, a driven roller 222, a conveying motor, a conveyor belt 223 and a partition plate 224. The feed box 21 extends to the mixing chamber 11. The active roller 221 and the driven roller 222 are both rotatably connected to the feed box 21. The conveying motor is coaxially fixedly connected to the active roller 221. The conveyor belt 223 is sleeved between the active roller 221 and the driven roller 222. The partition plate 224 is vertically fixedly connected to the outer surface of the conveyor belt 223.

[0053] The material is filled into the feed box 21 through the feed port 23, and the conveying motor drives the active roller 221 to rotate. The rotation of the driving roller causes the upper surface of the conveyor belt 223 to move toward the mixing chamber 11 with the cooperation of the driven roller 222, thereby continuously transferring the material in the feed box 21 toward the mixing chamber 11.

[0054] The partition plate 224 prevents the material from rolling down due to the influence of gravity, so that the conveyor belt 223 can smoothly convey the material to the mixing chamber 11.

[0055] A recovery slope 8 is provided below the screening bucket 71, and the recovery slope 8 extends into the feed box 21, and one end of the feed box 21 is lower than the other end below the screening bucket 71. The setting of the recovery slope 8 allows the remaining materials screened by the screening bucket 71 to enter the feed box 21 again along the recovery slope 8, and be reused in the granulation process, thereby avoiding waste of materials.

[0056] Since the recycled materials are extruded by the extrusion assembly 4 to form material blocks, when the material blocks are mixed and extruded again for granulation, the material blocks will cause difficulty in forming in the subsequent extrusion granulation process. Therefore, the mixing assembly 3 in this embodiment includes a mixing drive 31, a stirring rod 32 and a crushing member 33.

[0057] When the feeding component 2 conveys the material and the material blocks into the mixing chamber 11 synchronously, the mixing drive 31 drives the stirring rod 32 and the crushing element 33 to move at the same time, so that the stirring rod 32 can fully mix the material in the mixing chamber 11, and at the same time the crushing element 33 can break up the material blocks in the mixing chamber 11 into materials again, thereby avoiding the problem of difficult molding caused by the material blocks in the subsequent extrusion granulation process.

[0058] Reference Figure 4-5The mixing drive member 31 in this embodiment is installed on the top of the granulation box 1, and a rotating seat 34 is coaxially fixedly connected to the output shaft of the mixing drive member 31. The rotating seat 34 is located at the top of the mixing chamber 11. The stirring rod 32 is fixedly connected to the rotating seat 34, and the stirring rod 32 is located at the eccentric position of the output shaft of the mixing drive member 31. The stirring rod 32 is set in a semi-arc shape, so that the stirring rod 32 can destroy the symmetry of the circulation path during the stirring process, thereby effectively suppressing the swirling phenomenon, thereby reducing the flow dead zone of material mixing, and making the mixing effect of the materials during the stirring process better.

[0059] The crushing member 33 is rotatably connected to the rotating seat 34, and the crushing member 33 is also located at an eccentric position of the output shaft of the mixing drive member 31. The crushing member 33 is located on one side of the stirring rod 32, and the output shaft of the mixing drive member 31 is located between the crushing member 33 and the stirring rod 32. When the mixing drive member 31 drives the rotating seat 34 to rotate, the stirring rod 32 is driven to rotate. During the rotation of the stirring rod 32, different mixed materials are continuously pushed onto the crushing member 33, and the material blocks in the mixed materials are continuously crushed by the crushing member 33 to re-form powdered materials. Therefore, the stirring rod 32 not only has the effect of making the mixing effect of the materials better, but also has the effect of facilitating the crushing member 33 to fully crush.

[0060] The stirring rod 32 and the crushing member 33 are installed on the rotating seat 34, so that the mixing drive member 31 drives the rotating seat 34 to rotate, and at the same time drives the stirring rod 32 and the crushing member 33 to rotate around the axis of the mixing drive member 31, so that the materials in the mixing chamber 11 are fully mixed.

[0061] The crushing member 33 includes a crushing rod 331, a crushing leaf 332 and a synchronous member 333. The crushing rod 331 is connected to the rotating seat 34 in a vertical rotation manner, and the crushing leaf 332 is fixedly connected to the end of the crushing rod 331 away from the bottom of the granulation box 1. The synchronous member 333 includes a fixed gear ring 3331, a fixed plate 3332, a rotating gear ring 3333 and a crushing gear 3334. In other embodiments, the synchronous member 333 can also adopt a synchronous wheel, which is used to cooperate with the inner wall of the accommodating cavity to drive the crushing rod 331 to rotate.

[0062] The fixed gear ring 3331 is horizontally opened on the inner wall of the mixing chamber 11, the fixed plate 3332 is fixedly connected to the stirring rod 32, the rotating gear ring 3333 is rotatably connected to the fixed plate 3332, and the rotating gear ring 3333 is meshed with the fixed gear ring 3331, and the crushing gear 3334 is fixedly connected to the crushing rod 331, and the crushing gear 3334 is meshed with the inner side of the rotating gear ring 3333.

[0063] The diameter of the rotating gear ring 3333 in this embodiment is much larger than the diameter of the crushing gear 3334, so the crushing rod 331 has a larger transmission ratio. Therefore, when the rotating seat 34 rotates to drive the stirring rod 32 and the crushing rod 331 to rotate synchronously, the outer ring of the rotating gear ring 3333 rotates under the engagement with the fixed gear ring 3331, and the inner ring of the rotating gear ring 3333 drives the crushing gear 3334 to rotate under the engagement with the crushing gear 3334. Since the diameter of the rotating gear ring 3333 is much larger than the diameter of the crushing gear 3334, the crushing gear 3334 rotates several times for each rotation of the rotating gear ring 3333, so the rotation speed of the crushing gear 3334 is faster, and the rotation speed of the crushing gear 3334 is synchronized to the crushing rod 331, so that the rotation speed of the crushing rod 331 is faster, and then the crushing rod 331 drives the crushing blade 332 to rotate faster. The stirring rod 32 is used to push the material blocks in the mixed material toward the crushing blade 332 during the rotating mixing process, so that the crushing blade 332 can fully collide with the material blocks in the mixed material during the rapid rotation, thereby crushing the material blocks in the mixed material into powdery materials, so that the crushing effect of the crushing blade 332 is better, and the proportion of material blocks in the mixing chamber 11 is greatly reduced.

[0064] The mixing drive member 31 is used to drive the rotating seat 34 to rotate. When the rotating seat 34 rotates, the stirring rod 32 and the crushing rod 331 are driven to rotate synchronously around the axis of the rotating seat 34. When the stirring rod 32 and the crushing rod 331 rotate around the axis of the rotating seat 34, the recycled material and the newly added material are fully mixed, so that the material ratio of the finished product is more uniform.

[0065] When the stirring rod 32 rotates around the axis of the rotating seat 34, the stirring rod 32 drives the fixed plate 3332 and the rotating gear ring 3333 to rotate synchronously around the axis of the rotating seat 34. At this time, the fixed gear ring 3331 drives the meshing rotating gear ring 3333 to rotate. The rotation of the rotating gear ring 3333 drives the crushing gear 3334 to rotate rapidly. The rapid rotation of the crushing gear 3334 drives the crushing rod 331 and the crushing leaves 332 to rotate rapidly, thereby crushing the material blocks into materials again, avoiding the problem of difficult molding of the material blocks in the subsequent extrusion granulation process, thereby improving the compactness of the particles in the granulation process.

[0066] Reference Figure 1 and Figure 2A blocking plate 24 is installed at the connection between the mixing chamber 11 and the extrusion chamber 12, and a telescopic cylinder 25 is fixedly connected to one side of the blocking plate 24. The telescopic cylinder 25 drives the blocking plate 24 to extend and retract, thereby controlling the connection between the mixing chamber 11 and the extrusion chamber 12. When the mixing chamber 11 and the extrusion chamber 12 need to be connected, the telescopic cylinder 25 contracts so that the blocking plate 24 is separated from the connection between the mixing chamber 11 and the extrusion chamber 12, so that the mixing chamber 11 and the extrusion chamber 12 are connected; and when the mixing chamber 11 and the extrusion chamber 12 need to be separated, the telescopic cylinder 25 extends so that the blocking plate 24 is located at the connection between the mixing chamber 11 and the extrusion chamber 12, so that the mixing chamber 11 and the extrusion chamber 12 are separated.

[0067] The extrusion assembly 4 includes two extrusion rollers 41 that are attached to each other and an extrusion driving member 42 that drives the extrusion rollers 41 to rotate. In this embodiment, the hybrid driving member 31 and the extrusion driving member 42 are both driving motors.

[0068] The extrusion rollers 41 are rotatably connected in the extrusion chamber 12, and a plurality of molding grooves 43 are correspondingly opened on the surfaces of the two extrusion rollers 41. The extrusion driving member 42 is used to drive the two extrusion rollers 41 that are in contact with each other to rotate downward. The two extrusion rollers 41 that are in contact with each other are used to extrude the material so that the material is filled in the molding grooves 43, and the powdered material is formed into granules.

[0069] In this embodiment, a cleaning rod 9 is further provided between the squeezing roller 41 and the separation rod 51, and a plurality of cleaning brushes 91 are fixedly connected to the cleaning rod 9, and the cleaning brushes 91 abut against the surface of the squeezing roller 41. The cleaning rod 9 is connected to the transmission assembly 6, so that when the squeezing roller 41 rotates, the rotation direction of the cleaning rod 9 is opposite to the rotation direction of the squeezing roller 41. The cleaning rod 9 is used to further clean the residual material on the surface of the squeezing roller 41, so that the surface of the cleaning rod 9 is cleaner, which is convenient for the next extrusion granulation of the squeezing roller 41.

[0070] The separation assembly 5 includes two rotating separation rods 51 , which are rotatably connected to the granulation box 1 , and a plurality of separation sticks 52 are fixedly connected to the two separation rods 51 , and the separation sticks 52 on adjacent separation rods 51 are arranged alternately.

[0071] Reference Figure 3 and Figure 6 The transmission assembly 6 in this embodiment includes a driving gear plate 61, a driven gear plate 62 and a transmission belt 63. The driving gear plate 61 is coaxially fixedly connected to the hybrid drive member 31, the driving gear plate 61 is coaxially fixedly connected to one of the squeezing rollers 41, and the driven gear plate 62 is coaxially fixedly connected to the other squeezing roller 41. The driving gear plate 61 is meshed with the driven gear plate 62, so that when the hybrid drive member 31 drives the driving gear plate 61 and the squeezing roller 41 on one side to move, the driven gear plate 62 and the squeezing roller 41 on the other side move synchronously.

[0072] The transmission belt 63 is sleeved between the cleaning rod 9 and the squeezing roller 41 which are closest to each other, that is, the two vertical cleaning rods 9 and the squeezing roller 41 are mutually transmitted by the transmission belt 63. When the squeezing roller 41 rotates, the cleaning rod 9 is driven to rotate, so that the cleaning brush 91 on the cleaning rod 9 rotates to clean the material residue on the squeezing roller 41.

[0073] Each cleaning rod 9 is coaxially fixedly connected with a driving gear 64, and each separating rod 51 is coaxially fixedly connected with a driven gear 65. A main transmission gear 66 and a slave transmission gear 67 are arranged between the driving gear 64 and the driven gear 65 arranged vertically, and the main transmission gear 66 is meshed with the driving gear 64, and one side of the slave transmission gear 67 is meshed with the main transmission gear 66 and the other side is meshed with the driven gear 65. When the cleaning rod 9 rotates, the separation rod 51 is driven to rotate by the transmission of the driving gear 64, the main transmission gear 66, the slave transmission gear 67 and the driven gear 65, so that the sides of the separation rods 51 that are close to each other rotate upward, thereby separating the materials squeezed by the squeezing roller 41, so that the finished products are clearly separated.

[0074] The hybrid drive member 31 is used to drive the active toothed disc 61 and the squeezing roller 41 to rotate synchronously, and the active toothed disc 61 drives the driven toothed disc 62 to rotate, so that the sides of the two squeezing rollers 41 that are in contact with each other are synchronously squeezed and rotated downward to complete the squeezing of the material.

[0075] The squeezing roller 41 rotates to drive the cleaning rod 9 to rotate using the transmission belt 63. The rotation direction of the cleaning rod 9 is the same as that of the squeezing roller 41. Therefore, the moving directions of the cleaning brush 91 and the squeezing roller 41 are opposite, so that the cleaning brush 91 can smoothly clean the residue on the squeezing roller 41.

[0076] When the cleaning rod 9 rotates, the driving gear 64 is driven to rotate, and the driving gear 64 rotates synchronously to drive the main transmission gear 66 to rotate, and the main transmission gear 66 rotates to drive the meshing slave transmission gear 67 to rotate, and the slave transmission gear 67 rotates to drive the driven gear 65 to rotate, so that the separation rod 51 is rotated, and the rotation direction of the separation rod 51 is opposite to the rotation direction of the cleaning rod 9, so that the separation rod 52 on the side close to each other of the separation rod 51 rotates upward, thereby breaking up the finished products stuck together into separated particles.

[0077] Through the transmission of the driving toothed disc 61, the driven toothed disc 62, the transmission belt 63, the driving gear 64, the main transmission gear 66, the slave transmission gear 67 and the driven gear 65, the coordinated movement of the rod squeezing roller 41, the cleaning rod 9 and the separation rod 51 can be synchronously driven by the power source of the squeezing driving member 42.

[0078] The implementation principle of a compound fertilizer granulation equipment in an embodiment of the present application is: the compound fertilizer is added into the feed box 21 from the feed port 23 according to the proportion of the ingredients, the conveying motor drives the active roller 221 to rotate, and the driving roller rotates so that the upper surface of the conveyor belt 223 moves toward the mixing chamber 11 with the cooperation of the driven roller 222, and the partition plate 224 continuously transfers the material in the feed box 21 toward the mixing chamber 11, so that the material is transferred to the mixing chamber 11.

[0079] Then, the mixing drive 31 is started to control the stirring rod 32 to stir the mixing chamber 11 fully. The stirring rod 32 and the output shaft of the mixing drive 31 are eccentrically arranged so that the stirring rod 32 can destroy the symmetry of the circulation path during the stirring process, thereby effectively suppressing the swirling phenomenon, thereby reducing the flow dead zone of the material mixing, and making the material mixing more uniform. After the materials in the mixing chamber 11 are mixed, the telescopic cylinder 25 contracts and drives the blocking plate 24 to separate from the connection between the mixing chamber 11 and the extrusion chamber 12, and connects the mixing chamber 11 with the extrusion chamber 12 so that the mixed materials in the mixing chamber 11 fall between the two extrusion rollers 41, and the extrusion drive 42 drives the active toothed disc 61 to rotate, and the active toothed disc 61 rotates to drive the driven toothed disc 62 to rotate, and the active toothed disc 61 and the driven toothed disc 62 rotate to respectively drive the two extrusion rollers 41 to rotate downward synchronously on the sides of the two extrusion rollers 41 that are in contact with each other, so that the materials located between the extrusion rollers 41 are extruded and formed in the molding groove 43.

[0080] The extruded material falls into the separation chamber 13, and the rotation of the extrusion roller 41 drives the transmission belt 63 to rotate, and the rotation of the transmission belt 63 drives the cleaning rod 9 to rotate. The rotation of the cleaning rod 9 causes the cleaning brush 91 to rotate, so that the cleaning brush 91 moves in the opposite direction to the extrusion roller 41, so that the cleaning brush 91 cleans the material residue on the extrusion roller 41.

[0081] At the same time, the cleaning rod 9 rotates to drive the driving gear 64, and the driving gear 64 rotates synchronously to drive the main transmission gear 66 to rotate. The main transmission gear 66 rotates to drive the meshing slave transmission gear 67 to rotate, and the slave transmission gear 67 rotates to drive the driven gear 65 to rotate, so that the separation rod 51 rotates, and the rotation direction of the separation rod 51 is opposite to the rotation direction of the cleaning rod 9, so that the separation rod 52 on the side of the separation rod 51 that is close to each other rotates upward, so that the separation rod 52 breaks up the agglomerated finished products, so that the finished products separated by particles are discharged from the screening bucket 71, and the remaining material blocks are screened out from under the screening hole 72.

[0082] The screened material blocks are recovered into the feed box 21 along the recovery slope 8 , so that the recovered material blocks and the newly added material are transported to the mixing chamber 11 again by the conveying member 22 .

[0083] The mixing drive member 31 is started again, and the mixing drive member 31 drives the rotating seat 34 to rotate. When the rotating seat 34 rotates, the stirring rod 32 and the crushing rod 331 are driven to rotate synchronously around the axis of the rotating seat 34. When the stirring rod 32 rotates around the axis of the rotating seat 34, the stirring rod 32 continuously pushes different mixed materials onto the crushing member 33 during the rotation process. At the same time, the stirring rod 32 drives the fixed plate 3332 and the rotating gear ring 3333 to rotate synchronously around the axis of the rotating seat 34. The outer ring of the rotating gear ring 3333 is aligned with the fixed gear ring 33 31, the inner ring of the rotating gear ring 3333 drives the crushing gear 3334 to rotate under the engagement with the crushing gear 3334. Since the diameter of the rotating gear ring 3333 is much larger than the diameter of the crushing gear 3334, each rotation of the rotating gear ring 3333 will drive the crushing gear 3334 to rotate several times. Therefore, the rotation speed of the crushing gear 3334 is faster. The rapid rotation of the crushing gear 3334 drives the crushing rod 331 and the crushing blade 332 to rotate rapidly, thereby crushing the material blocks into materials again.

[0084] The recycling slope 8 is used to recycle the material blocks to avoid waste. At the same time, the stirring rod 32 and the crushing rod 331 crush the material blocks into material powder, avoiding the problem of difficult molding caused by the material blocks in the subsequent extrusion granulation process, thereby improving the compactness of the particles in the granulation process.

[0085] The present application also discloses a granulation method comprising: Reference Figure 1 , use S1, add materials → S2, convey materials → S3, mix materials → S4, extrude materials → S5, separate finished products to complete the granulation of compound fertilizer.

[0087] First, potassium chloride, monoammonium phosphate, potassium ammonium sulfate, magnesium sulfate and potassium sulfate are poured into the feed box 21, and the materials in the feed box 21 are transported to the mixing chamber 11 by the conveying member 22. After the mixing is completed, the mixing chamber 11 is opened, and the mixed materials in the mixing chamber 11 fall between the two squeezing rollers 41. The squeezing driving member 42 drives the squeezing rollers 41 to rotate, and the materials between the two squeezing rollers 41 are squeezed into shape. The extruded compound fertilizer particles are driven by the transmission component 6 to rotate the separation rod 51, and the rotation of the separation rod 51 drives the separation rod 52 to separate the compound fertilizer particles that are stuck together after squeezing, so that the compound fertilizer particles with distinct particles are discharged from the screening bucket 71.

[0088] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
