Factors affecting soil fertility include the thickness of the soil tillage layer, the texture and structure of the tillage layer, the content of soil organic matter, the content of soil nutrients, and the pH value of the soil.

[0044] The preparation method of the soil conditioner comprises the following steps:

[0045] S01, placing the composite amino acid, sodium ferric EDTA and magnesium sugar alcohol in the corresponding storage boxes 616 respectively, and then controlling the storage boxes 616 on the linkage carrying ring 101 to synchronously perform circumferential motion, so that the raw materials in the storage boxes 616 are alternately dispersed and fall into the mixing preparation tank 1;

[0047] S03, the raw materials falling into the mixing preparation tank 1 are rotated and mixed by the multi-directional mixing mechanism 3 on the lifting control mechanism 2, and the multi-directional mixing mechanism 3 is moved up and down by the reciprocating screw 203 during the rotational mixing process;

[0048] S04. During the rotational mixing process, the horizontal conveyance of the raw materials is achieved by the rotation of the horizontal auger 305 on the multi-directional mixing mechanism 3, and the vertical conveyance of the raw materials is achieved by the rotation of the vertical auger 318 on the multi-directional mixing mechanism 3;

[0049] S05. Continue to place the biochar, bamboo powder and fine soil in the corresponding storage boxes 616, and mix the raw materials according to the above steps S01 to S04.

[0050] In this embodiment of the present invention, a linkage support ring 101 is rotatably installed on the top of the mixing preparation tank 1, and a travel transmission rod 102 is rotatably arranged on the linkage support ring 101, and a first travel gear 103 is fixedly installed on the top of the travel transmission rod 102.

After opening the control valve 107 on the water inlet pipe 105, a certain amount of water can be transported to the mixing preparation tank 1 through the water inlet pipe 105. After fully mixing the various raw materials in the mixing preparation tank 1, the control valve 107 on the material extraction pipe 106 is opened to extract the prepared slurry from the mixing preparation tank 1 and enter the granulation equipment to achieve granulation. After granulation, the granular soil conditioner can be obtained after drying.

[0051] In this embodiment of the present invention, the lifting control mechanism 2 includes an annular base 201 rotatably engaged in the annular mounting groove 104, and two scraping parts 202 are symmetrically fixedly installed on the top of the annular base 201, and the scraping parts 202 slide and fit on the inner wall of the mixing preparation tank 1. During the rotation of the lifting control mechanism 2, the raw materials attached to the inner wall of the mixing preparation tank 1 can be continuously dropped down by the rotating scraping parts 202, thereby improving the mixing effect between different raw materials. The reciprocating screw 203 is rotatably connected with the corresponding scraping part 202, and the upper end of the reciprocating screw 203 slides through the linkage bearing ring 101 and is fixedly installed with a second traveling gear 204. An outer tooth ring 205 is arranged on the top of the linkage bearing ring 101, and the reciprocating screw 203 and the traveling transmission rod 102 are both rotatably connected with the outer tooth ring 205, thereby enabling the reciprocating screw 203, the traveling transmission rod 102 and the outer tooth ring 205 to always be able to revolve synchronously with the linkage bearing ring 101.

[0052] In this embodiment of the present invention, the multi-directional mixing mechanism 3 includes a first connecting seat 301 slidably mounted on the reciprocating screw rod 203 and a second connecting seat 302 slidably fitted inside the corresponding scraper portion 202, a horizontal conveying pipe 303 is fixedly installed between the first connecting seat 301 and the second connecting seat 302, the horizontal conveying pipe 303 and the inner cavity of the second connecting seat 302 are communicated with each other, a partition plate 304 is fixedly arranged inside the horizontal conveying pipe 303, a horizontal auger 305 is arranged inside the horizontal conveying pipe 303 and is rotatably connected to the partition plate 304, and the horizontal conveying pipe 303 A first inlet 306 is provided on the side close to the first connecting seat 301, and a first outlet 307 is provided on the side close to the second connecting seat 302 of the horizontal conveying pipe 303. In the process of controlling the lifting control mechanism 2 to rotate, the raw materials at the first inlet 306 can be gradually transported into the horizontal conveying pipe 303 through the continuously rotating horizontal auger 305, and then discharged from the horizontal conveying pipe 303 through the first outlet 307, thereby achieving sufficient mixing of the raw materials in the horizontal direction inside the mixing preparation tank 1, thereby greatly improving the mixing effect between different raw materials.

[0053] In this embodiment of the present invention, a vertical sleeve 308 that slides with the corresponding scraper part 202 is fixedly installed on the top of the first connecting seat 301, the vertical sleeve 308 is sleeved on the reciprocating screw rod 203 and a lifting control part 309 is fixed on the top of the vertical sleeve 308, the lifting control part 309 and the reciprocating screw rod 203 are in transmission cooperation, a first bevel gear 310 located in the inner cavity of the second connecting seat 302 is fixedly installed at one end of the horizontal auger 305, a second bevel gear 311 that meshes with the first bevel gear 310 is connected to the inner cavity of the second connecting seat 302 through a rotating shaft, a vertical linkage pipe 312 that slides with the corresponding scraper part 202 is fixedly installed on the top of the rotating shaft, a limited position groove is provided on the side surface of the travel transmission rod 102, and the vertical linkage pipe 312 is sleeved on the travel transmission rod 102 The limit piece fixed on the inner wall of the vertical linkage pipe 312 is slidably fitted in the limit groove. In the process of controlling the lifting control mechanism 2 to rotate, the self-rotating travel transmission rod 102 drives the vertical linkage pipe 312 to rotate through the cooperation of the limit piece and the limit groove. The second bevel gear 311 rotating synchronously with the vertical linkage pipe 312 drives the first bevel gear 310 to rotate, thereby realizing the continuous rotation of the horizontal auger 305. The continuously rotating horizontal auger 305 can gradually transport the raw materials at the first inlet 306 to the inside of the horizontal conveying pipe 303, and then discharge the horizontal conveying pipe 303 from the first outlet 307, thereby realizing the full mixing of the raw materials in the horizontal direction inside the mixing preparation tank 1.

[0054] In this embodiment of the present invention, a supporting seat 313 is fixedly installed on the side of the horizontal conveying pipe 303, and a vertical conveying pipe 314 is fitted on the top of the supporting seat 313. A second inlet 315 and a second outlet 316 are respectively opened on the side of the vertical conveying pipe 314. A vertical limit rod 317 is fixedly installed on the top of the vertical conveying pipe 314. The vertical limit rod 317 can only move up and down but cannot rotate, thereby ensuring that the vertical conveying pipe 314 can only move up and down, and the bottom of the vertical conveying pipe 314 is always against the top of the supporting seat 313. The vertical auger 318 is arranged inside the vertical conveying pipe 314 and is fixedly connected to the supporting seat 313. During the rotation of the multi-directional mixing mechanism 3, the multi-directional mixing mechanism 3 rotates synchronously with the lifting control mechanism 2, so that the rotating horizontal conveying pipe 303 drives the vertical auger 318 to rotate, while the vertical conveying pipe 314 remains stationary. Under the action of the rotating vertical auger 318, the raw materials at the second inlet 315 in the mixing preparation tank 1 are gradually conveyed upward along the vertical conveying pipe 314, and then discharged from the vertical conveying pipe 314 through the second outlet 316, thereby realizing the vertical conveying of the raw materials. Under the joint action of horizontal conveying and vertical conveying, the mixing effect of different raw materials in the mixing preparation tank 1 can be greatly improved, thereby improving the efficiency of the mixing processing between various raw materials.

[0055] In this embodiment of the present invention, a mixing control mechanism 4 is installed on the mixing preparation tank 1, and the mixing control mechanism 4 includes a mixing control assembly 5; wherein the mixing control assembly 5 includes a supporting frame 501 fixedly installed on the mixing preparation tank 1, and an inner gear ring 502 fixedly connected to the supporting frame 501 is arranged above the mixing preparation tank 1, and the inner gear ring 502 is meshed with the first traveling gear 103 inside thereof. In the process of controlling the rotation of the lifting control mechanism 2, the multi-directional mixing mechanism 3 rotates synchronously with the lifting control mechanism 2, thereby causing the first traveling gear 103 to roll and travel along the inner wall of the inner gear ring 502, and the traveling transmission rod that rotates synchronously with the first traveling gear 103 102 drives the vertical linkage tube 312 to rotate, and the second bevel gear 311 that rotates synchronously with the vertical linkage tube 312 drives the first bevel gear 310 to rotate, thereby realizing the continuous rotation of the horizontal auger 305 while controlling the rotation of the multi-directional mixing mechanism 3. An arc-shaped inner gear seat 503 is installed on the circumference of the inner gear ring 502 through a connecting frame, and the second traveling gear 204 is adapted to the arc-shaped inner gear seat 503. A horizontal mounting frame 504 fixedly connected to the supporting frame 501 is provided on the mixing preparation tank 1, and a power gear 506 is connected to the output end of the mixing control motor 505 installed on the top of the horizontal mounting frame 504, and the power gear 506 is meshed with the outer gear ring 205.

[0056] After placing the complex amino acid, sodium ferric ethylenediaminetetraacetic acid and magnesium sugar alcohol respectively in the corresponding storage box 616, the mixing control motor 505 is started to control the power gear 506 to rotate, and the outer gear ring 205 is rotated under the meshing action of the power gear 506 and the outer gear ring 205. Since the reciprocating screw rod 203 and the travel transmission rod 102 are both installed on the outer gear ring 205, the reciprocating screw rod 203 and the travel transmission rod 102 can revolve synchronously with the outer gear ring 205. At the same time, since the reciprocating screw rod 203 and the travel transmission rod 102 are installed through the linkage bearing ring 101, the entire lifting control mechanism 2 can always revolve synchronously with the linkage bearing ring 101. 05 During the synchronous movement, the first traveling gear 103 on the top of the traveling transmission rod 102 rolls along the inner wall of the inner gear ring 502, and the traveling transmission rod 102 that rotates synchronously with the first traveling gear 103 drives the vertical linkage tube 312 to rotate, and the second bevel gear 311 that rotates synchronously with the vertical linkage tube 312 drives the first bevel gear 310 to rotate, thereby achieving continuous rotation of the horizontal auger 305 while controlling the rotation of the multi-directional mixing mechanism 3, and the rotating horizontal conveying pipe 303 drives the vertical auger 318 to rotate. Under the joint action of horizontal conveying and vertical conveying, the mixing effect of different raw materials in the mixing preparation tank 1 can be greatly improved, thereby improving the efficiency of mixing processing between various raw materials.

[0057] When the second traveling gear 204 contacts the arc-shaped inner tooth seat 503 and rolls along the arc-shaped inner tooth seat 503, the reciprocating screw 203 that rotates synchronously with the second traveling gear 204 drives the lifting control part 309 to move upward (the lifting control part 309 is initially located at the bottom of the spiral structure on the reciprocating screw 203). When the second traveling gear 204 is separated from the arc-shaped inner tooth seat 503, the lifting control part 309 moves up a short distance, and the vertical sleeve 308 that moves up synchronously with the lifting control part 309 drives the horizontal conveying pipe 303 to move up the same distance. The vertical linkage pipe 312 that moves upward synchronously with the horizontal conveying pipe 303 moves upward the same distance along the travel transmission rod 102, and then the horizontal auger 305 can be rotated to realize horizontal conveying and mixing of the raw materials at this position, and the rotating vertical auger 318 can be used to convey and mix the raw materials at this position in the vertical direction. When the second travel gear 204 contacts the arc-shaped inner gear seat 503 again and rolls along the arc-shaped inner gear seat 503, the horizontal auger 305 and the vertical auger 318 move upward the same distance again, and then the water is used again. The rotation of the horizontal auger 305 realizes the horizontal conveying and mixing of the raw materials at this position, and the rotating vertical auger 318 is used to convey and mix the raw materials at this position in the vertical direction.
