[0049] A method for preparing a biological bottom modification particle for aquaculture comprises the following steps:

[0050] Step 1: First, by running the motor 1 207, the fixedly connected rotating frame 210 can drive the push plate 211 to rotate inside the unloading frame 208, and then the material can be evenly transferred to the inside of the crushing box 301 by cooperating with the discharge port 209, thereby preventing the crushing roller 302 from being blocked during operation and improving the reliability of the device;

[0051] Step 2: After the material is transported to the crushing box 301, the motor 2 305 is operated, and then the bevel gear 1 307 and the bevel gear 2 309 are used together to achieve the work of crushing and grinding the material, and then the material is transported to the inside of the mixing barrel 401 through the crushing port 303, wherein the rotation of the connecting shaft 308 can drive the bevel gear 3 310 to rotate, and then under the action of the mounting frame 404 and the stirring blade 1 406 and the stirring blade 2 407, the material is crushed and mixed, thereby solving the problem of production rate;

[0052] Step three, by running the working motor three 417, the third gear 418 is rotated, and with the cooperation of the gear ring 416 and the rotating ring 414, the multiple trapezoidal blocks 415 can be rotated in a ring, and then the roller 413 will drive the connecting plate 412 and the scraper frame 409 to reciprocate and rise and fall, thereby achieving the effect of cleaning the inner wall of the mixing barrel 401.

[0053] Working principle: When the present invention is used, solid raw materials can first be placed into the material unloading frame 208 through the material box 205, and then the motor 207 is operated, so that the fixedly connected rotating frame 210 drives the push plate 211 to rotate inside the material unloading frame 208, and then the material is evenly unloaded into the crushing box 301 under the cooperation of the opened discharge port 209, thereby preventing the material from clogging the material inlet of the crushing box 301, so that the normal operation of the crushing component 3 can be effectively guaranteed;

[0054] After the material is transported to the crushing box 301, the motor 2 305 can be operated to rotate the fixed connecting shaft 308, thereby causing the two fixed bevel gears 2 309 to rotate at the same time. At this time, the two bevel gears 1 307 meshing with it will rotate towards each other at the same time, allowing the two fixedly connected crushing rollers 302 to rotate towards each other inside the crushing box 301, thereby achieving the effect of crushing and grinding the material. The crushed material can be transported to the mixing barrel 401 below through the crushing port 303. After the crushed powder is transported to the mixing barrel 401, the required body fluid raw materials, a certain amount of plasticizer and an appropriate amount of water can be injected into the mixing barrel 401. At the same time, after the connecting shaft 308 is rotated, The bevel gear 310 that is fixedly connected is rotated, thereby making the bevel gear 412 that is meshed with it drive the rotating shaft 313 to rotate, and then the first gear 402 that is fixedly connected will drive the second gear 403 that is meshed with it to rotate, and then the mounting frame 404 located inside the mixing barrel 401 will drive the two sets of stirring shafts 405 to rotate, and by setting the stirring blade 1 406 and the stirring blade 2 407, the mixing effect inside the mixing barrel 401 can be improved. After the materials are mixed, the raw materials can be taken out from the mixing barrel 401 by opening the valve 410, thereby achieving the mixing of the materials, thereby solving the problem that the crushing needs to be operated step by step during mixing, resulting in low efficiency and affecting the preparation production rate;

[0055] When the inner wall of the mixing barrel 401 needs to be cleaned, the motor 3 417 is run to rotate the third gear 418 fixedly connected thereto. At this time, the gear ring 416 meshing with the third gear 418 rotates under the action of the rotating ring 414. Then, with the cooperation of a number of trapezoidal blocks 415, the roller 413 drives the connecting plate 412 to move up and down. Subsequently, the top shaft 411 fixedly connected thereto drives the scraper frame 409 to move up and down under the action of the sliding shaft 408, thereby realizing the work of cleaning the inner wall of the mixing barrel 401.
