Through the cooperation of the limiting groove 201 and the limiting block 202, the mixing tank 101 can slide up and down in the carrying frame 001.

[0023] The crushing and shaking assembly 003 disposed in the mixing tank 101 includes a transmission shaft 301, which is rotatably connected to the lower inner wall of the mixing tank 101. A sieve plate 302 is installed on the inner wall of the feed frame 102, and the center of the sieve plate 302 is connected to the transmission shaft 301 through the center. The sieve plate 302 can ensure that the fertilizer raw materials passing through the feed frame 102 are screened and the particle size thereof remains consistent, thereby improving the quality of fertilizer production.

[0024] The stirring assembly 004 disposed in the transmission shaft 301 includes a positioning cylinder 401 , which is sleeved and fixed on the transmission shaft 301 , and three groups of rotating cylinders 402 are rotatably connected to the outer side of the positioning cylinder 401 in a circular shape.

[0025] The transmission shaft 301 can drive the positioning cylinder 401 to rotate, so that the three groups of rotating cylinders 402 can stir and mix the fertilizer raw materials at the same time.

[0026] Furthermore, in the above structure, the stirring and shaking assembly 002 also includes a connecting tube 203, which is installed in a ring-shaped distribution below the inner wall of the supporting frame 001, and a T-shaped rod 204 is installed in a ring-shaped distribution at the bottom of the mixing tank 101, and the T-shaped rod 204 is connected to the corresponding connecting tube 203 in a limited sliding manner, and a spring 205 is sleeved on the T-shaped rod 204, and the two sides of the spring 205 are respectively fitted and connected to the upper part of the inner wall of the connecting tube 203 and the lower part of the T-shaped rod 204.

[0027] The T-shaped rod 204 can be kept in position in the connecting tube 203 by means of the spring 1 205 , so that the mixing tank 101 can be reset in time after moving upward in the carrying frame 001 .

[0028] Furthermore, in the above structure, a motor 206 is installed at the bottom of the supporting frame 001, an output shaft 207 is rotatably connected to the lower part of the supporting frame 001, and the output shaft 207 is axially connected to the output end of the motor 206, and a guide block 208 is symmetrically installed on the output shaft 207, a docking tube 209 is rotatably connected to the bottom of the mixing tank 101, and the docking tube 209 is axially connected to the transmission shaft 301, and a guide groove 210 is symmetrically opened on the inner wall of the docking tube 209, and the guide groove 210 is slidably connected to the corresponding guide block 208.

[0029] The output shaft 207 is driven to rotate by the motor 206 , and the cooperation between the guide block 1 208 and the guide groove 1 210 can make the docking sleeve 209 rotate, thereby rotating the transmission shaft 301 .

[0030] Furthermore, in the above structure, an extrusion ring 211 is installed at the bottom of the docking tube 209, and an extrusion ring 212 is installed below the inner wall of the supporting frame 001. The interior of the extrusion ring 212 is sleeved with the output shaft 207, and the extrusion ring 1 211 and the extrusion ring 2 212 are in contact with each other.

[0031] During the rotation of the docking tube 209, the extrusion ring 1 211 and the extrusion ring 2 212 are fitted together to form an extrusion fit, so that the extrusion ring 1 211 drives the docking tube 209 to move upward, thereby making the mixing tank 101 upward as a whole, and can be reset in time under the action of the spring 1 205, so that the mixing tank 101 produces a shaking effect, thereby stirring and shaking the mixed fertilizer to avoid sedimentation.

[0032] Furthermore, in the above structure, the crushing shaking assembly 003 also includes a fixed frame 303, which is installed above the inner wall of the feed frame 102, and a guide rod 304 is installed below the fixed frame 303, and the bottom of the guide rod 304 is connected to the top of the transmission shaft 301.

[0033] The cooperation between the guide rod 304 and the transmission shaft 301 allows the transmission shaft 301 to rotate more smoothly.

[0034] Furthermore, in the above structure, a second guide groove 305 is symmetrically opened on the upper inner wall of the transmission shaft 301, a protective tube 306 is sleeved on the guide rod 304 and the transmission shaft 301, a second guide block 307 is symmetrically installed on the inner wall of the protective tube 306, and the second guide block 307 is slidingly connected to the corresponding second guide groove 305, a second spring 308 is sleeved on the transmission shaft 301, and the two sides of the second spring 308 are respectively in contact with the bottom of the guide rod 304 and the inner wall of the protective tube 306.

[0035] Through the cooperation of the second guide groove 305 and the second guide block 307 , the protective tube 306 can rotate along with the transmission shaft 301 , and the second spring 308 can ensure the stability of the position of the protective tube 306 during the rotation process.

[0036] Furthermore, in the above structure, three groups of extrusion rollers 309 are rotatably connected to the outside of the protective cylinder 306, and the extrusion rollers 309 are in contact with the surface of the sieve plate 302. An extrusion ring 310 is installed below the protective cylinder 306, and an extrusion ring 4 311 is installed above the sieve plate 302. The interior of the extrusion ring 4 311 is penetrated by the transmission shaft 301, and the extrusion ring 4 311 is in contact with the extrusion ring 310.

[0037] Through the cooperation of the extrusion ring four 311 and the extrusion ring three 310, the protective cylinder 306 can be continuously shaken up and down during the rotation process, so that the extrusion roller 309 can be continuously shaken up and down when rotating on the surface of the screen plate 302, so that the fertilizer can be effectively rolled and crushed, so that the fertilizer raw materials can be transported downward along the screen plate 302.

[0038] Furthermore, in the above structure, the stirring assembly 004 also includes three sets of bevel gears 403, which are installed on the outside of the three sets of rotating cylinders 402. A bevel gear ring 404 is installed on the inner wall of the mixing tank 101, and the bevel gear ring 404 is engaged with the three sets of bevel gears 403. There are multiple sets of fixed cylinders 405 distributed in a ring shape on the inner wall of the rotating cylinder 402 and fixedly connected therewith. A stirring rod 406 is positioned and connected inside the fixed cylinder 405, and a bevel gear 2 407 is installed on the end of the stirring rod 406 close to the inside of the fixed cylinder 405.

[0039] Through the cooperation of bevel gear 1 403 and bevel gear ring 404, the rotating cylinder 402 can rotate itself while following the rotation of the transmission shaft 301, so that the stirring rod 406 can turn the mixed raw materials to prevent them from sinking to the bottom, and can also stir and mix them.

[0040] Furthermore, in the above structure, three groups of fixed shafts 408 are installed in a ring-shaped distribution on the outside of the positioning cylinder 401, and the fixed shafts 408 are rotatably connected to the inner wall of the corresponding rotating cylinder 402. Bevel gear three 409 is sequentially sleeved and fixed on the three groups of fixed shafts 408, and bevel gear three 409 is engaged with the corresponding bevel gear two 407.

[0041] The rotation of the rotating drum 402 can cause the stirring rod 406 to rotate, so that the bevel gear 2 407 can move along the bevel gear 3 409, thereby causing the stirring rod 406 to rotate, achieving the self-rotation effect of the stirring rod 406, thereby increasing its stirring effect.

[0042] like Figure 1-9 As shown, by placing the fertilizer raw materials into the feed frame 102, by starting the motor 206, the motor 206 drives the output shaft 207 to rotate, thereby rotating the transmission shaft 301, and the mixing tank 101 as a whole will vibrate up and down, and the extrusion roller 309 will roll up and down on the sieve plate 302 to crush the raw materials, so that the raw materials can be effectively crushed. At the same time, the overall vibration of the mixing tank 101 can ensure that the crushed raw materials are shaken and flattened, so that the raw materials fall into the mixing tank 101 along the sieve plate 302. At this time, after each group of raw materials is crushed and falls into the inside of the mixing tank 101, the transmission shaft 301 can drive the three groups of rotating drums 402 to rotate as a whole, and the bevel gear 1 403 moves along the bevel gear ring 404, so that the rotating drum 402 drives the stirring rod 406 to rotate, so that the rotating drum 402 can rotate as a whole to stir the raw materials while also stirring them by self-rotation.

[0043] At the same time, during the rotation of the rotating drum 402, each group of stirring rods 406 can rotate independently, thereby improving the stirring effect while also turning over the mixed raw materials, and cooperating with the shaking of the mixing tank 101 can effectively avoid sedimentation. Through this structure, various raw materials can be effectively crushed before mixing, which can avoid agglomeration and ensure that the particle size of each group of raw materials remains consistent. During the mixing process, the transmission shaft 301 can drive the rotating drum 402 to rotate and stir, so that the rotating drum 402 rotates, and the stirring rods 406 can rotate independently, thereby avoiding sedimentation of the raw materials, achieving the effect of improving the stirring quality, and thus improving the overall quality of fertilizer processing.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
