[0049] Reference Figure 1-Figure 11This embodiment also proposes a method for preparing mineral source fertilizer for sandy saline-alkali soil, which is applicable to the above-mentioned device for preparing mineral source fertilizer for sandy saline-alkali soil, and the steps are as follows:

[0050] S1: Put the mineral source fertilizer raw material into the inside of the feeding funnel 509, and then start the second motor 510. The mineral raw material falls to the top of the second filter plate 502 after being stirred by the spiral knife 508, and is ground for the first time under the grinding of the grinding roller 506;

[0051] S2: The mineral raw materials after the first grinding fall to the top of the first filter plate 311, and the reciprocating motor 304 is started. The reciprocating motor 304 drives the threaded cylinder 305 to rotate, and then the third threaded rod 309 drives the first filter plate 311 to move downward, so that the steel ball 403 falls to the top of the first filter plate 311;

[0052] S3: Driven by the second motor 510, the movable rod 416 and the hammer head 417 rotate, and under the action of centrifugal force, the hammer head 417 beats the scraper 413, so that the scraper 413 scrapes the inner wall of the dry powder cylinder 401, and the hammer head 417 stirs the mineral raw material;

[0053] S4: The stirred mineral raw materials fall into the soaking cylinder 201 for soaking, and driven by the first motor 202, the vertical stirring plate 208 stirs the mixture up and down, and the aeration head 224 aerates the mixture;

[0054] S5: The soaked solution is discharged through the discharge port at the bottom of the base 1, and packaging or granulation operation is selected according to needs.

[0055] Specifically, the working process or working principle of the mineral source fertilizer preparation device for sandy saline-alkali soil is as follows: first, the staff starts the first motor 202 and the second motor 510 through the control panel, and the second motor 510 can drive the spiral cutter 508 to rotate, and the spiral cutter 508 can crush the ore to decompose the volume of the ore into particles of a size suitable for grinding. The rotation of the spiral cutter 508 can drive the rotation of the half gear 503. When the half gear 503 rotates, the fourth gear 504 can be rotated intermittently, and the rotation of the fourth gear 504 can drive the mounting rod 505 to rotate, so that the grinding roller 506 can intermittently grind the mineral raw materials on the top of the second filter plate 502, and the ground mineral raw materials pass through the second filter plate 5 02 falls onto the surface of the first filter plate 311. When the half gear 503 rotates, it can drive the second mounting plate 415 to rotate. At the same time, the rotation of the second mounting plate 415 can drive the telescopic rod 414 to rotate, and then drive the first filter plate 311 to rotate. When the second mounting plate 415 rotates, it can drive the movable rod 416 to rotate. The movable rod 416 rotates under the action of centrifugal force, so that the movable rod 416 changes from a vertical state to an inclined state. When the movable rod 416 tilts, the hammer head 417 at the end of the movable rod 416 can hammer the scraper 413. Under the hammering of the hammer head 417, the scraper 413 slides inside the second sliding groove 411, so that the inner wall of the dry powder cylinder 401 can be scraped.

[0056] When there are enough mineral raw materials on the top of the first filter plate 311, the reciprocating motor 304 is started, and the reciprocating motor 304 can drive the threaded barrel 305 to reciprocate. When the threaded barrel 305 rotates, the rotating threaded barrel 305 can make the third threaded rod 309 move downward, and the downward movement of the third threaded rod 309 can drive the first filter plate 311 to move downward. The first filter plate 311 moving downward can make the third gear 407 rotate, and then drive the second gear plate 408 to move upward, so that the baffle plate 406 slides upward on the surface of the first slide rod 405, so that the baffle plate 406 no longer contacts the first mounting groove 408. 04 is blocked, at this time, the steel balls 403 inside the placement box 402 fall onto the surface of the first filter plate 311, and the rotation of the first filter plate 311 can make the steel balls 403 on the top of the first filter plate 311 collide with each other, so that the mineral raw materials can be mixed in different directions. When the first filter plate 311 rotates, the mineral raw materials on the top of the first filter plate 311 fall into the gap between the grinding seat 308 and the first filter plate 311 through the filter holes on the surface of the first filter plate 311. The rotating first filter plate 311 and the grinding seat 308 can perform secondary grinding on the mineral raw materials to make the mineral particles finer and increase their specific surface area.

[0057] When the first gear 203 rotates driven by the first motor 202, the rotating first gear 203 can drive the second gear 222 to rotate, and then drive the first rotating shaft 205 to rotate. The rotation of the first rotating shaft 205 can drive the rotating disk 213 to rotate. The rotation of the rotating disk 213 can drive the eccentric plate 214 to rotate eccentrically. The rotation of the eccentric plate 214 can make the cross bar 215 reciprocate, and then drive the first mounting plate 216 to reciprocate. The reciprocating motion of the first mounting plate 216 can drive the second threaded rod 217 to reciprocate inside the gear rod 206, so that the gear rod 206 can rotate reciprocatingly. The reciprocating rotation of the gear rod 206 can drive the first tooth plate 210 to reciprocate up and down inside the first sliding groove 209, and the up and down reciprocating motion of the first tooth plate 210 can drive the vertical stirring plate 208 to reciprocate up and down, so that the mineral raw materials accumulated at the bottom of the soaking cylinder 201 can be stirred.

[0058] When the first mounting plate 216 performs reciprocating motion, the reciprocating rod 218 can be driven to perform reciprocating motion, thereby driving the piston 219 to perform reciprocating motion. When the piston 219 performs reciprocating motion inside the gas cylinder 221, the gas inside the gas cylinder 221 can be compressed, and the airflow passes through the first air pipe 220 and the main pipe 223 and is ejected from the aeration head 224, so that the interior of the soaking cylinder 201 can be aerated. At the same time, the airflow enters the interior of the jet head 512 through the second air pipe 511, and blows air to the surface of the second filter plate 502 to avoid blockage of the second filter plate 502 and affect the filtration efficiency.
