A linear motor is pre-installed in each of the two sliding grooves 9, which can drive the two second sliding blocks to move up and down in the sliding groove 9 after starting, and drive the circular ring 7 to move up and down synchronously.

[0043] As a technical optimization scheme of the present application, the third sliding block 21 is slidingly installed in the second circular groove 20, the top of the third sliding block 21 is rotatably installed with a rotating block, the end of the rotating block away from the third sliding block 21 is connected with a mounting seat 23 through a fifth electric telescopic rod 22, the inside of the mounting seat 23 is symmetrically hinged with a fan 8 and a plurality of telescopic pipes 24, the telescopic ends of the plurality of telescopic pipes 24 are all installed with spray heads 19, the bottom end of the mounting seat 23 is installed with a protruding part 25, and the ends of the two moving plates 14 away from each other are all provided with a slot 38 matched with the protruding part 25.

An arc linear motor is pre-installed in the second circular groove 20, which can drive the third sliding block 21 to move in the second circular groove 20.

[0044] In the present application, when a user uses the device, the soil block to be crushed is placed in the inside of the feeding box 3, and the soil block is located between the first filter plate 13 and the push plate 11. The extension of the telescopic end of the two first electric telescopic rods 10 is controlled to move the push plate 11 towards the first filter plate 13, so that the push plate 11 and the first filter plate 13 cooperate to crush the soil block. The light impurities and heavy objects such as stones mixed in the soil block will remain on the top of the second filter plate 12 after the soil block is crushed. The soil block crushed once will fall through the first filter plate 13 and the second filter plate 12 to the inside of the crushing box 2. The plurality of crushing knives 26 driven by the high-speed rotating shaft 4 can crush the soil block twice. Finally, the crushed soil after two crushing processes will accumulate on the inner bottom surface of the crushing box 2.

[0045] In order to meet the nutrients for rice seedling raising, the fertilizer can be put into the inside of the crushing box 2 through the feeding port 18. At this time, the plurality of crushing knives 26 in the crushing box 2 can crush the granular fertilizer. Then, the rotating rod and the plurality of stirring blades 29 on the outer wall thereof are driven by the second motor 28 to mix and stir the crushed soil and the fertilizer. Then, after the two sealing plates 30 are controlled to be opened, the crushed soil falls downward to the inside of the sieve plate 32 through the discharge port. After the screening treatment of the sieve plate 32, the crushed soil directly falls downward to the seedling tray pre-placed at the bottom of the crushing box 2 for tray filling. At this time, the linear motor in the two sliding grooves 9 can be controlled to start, so that the two second sliding blocks drive the annular ring 7 to move downward to the appropriate position. Then, the plurality of telescopic pipes 24 drive the plurality of spray heads 19 to rotate towards the direction close to the crushing box 2. By starting the external water outlet mechanism, the plurality of spray heads 19 can spray water near the discharge port of the crushing box 2, which is convenient for removing the dust generated in the process of filling the crushed soil into the tray and reducing the influence of dust on the surrounding environment.

[0046] Before the push plate 11 and the first filter plate 13 cooperate to squeeze and crush the relatively dry soil blocks, the linear motors inside the two chutes 9 can be controlled to drive the second slider and the circular ring 7 to move upward to the bottom of the first motor 6, and then the third slider 21 drives the mounting seat 23 and other components to move together in the second circular groove 20 to the position of the front of the equipment close to the chute 9, and then the rotating block drives the fifth electric telescopic rod 22 and the mounting seat 23 and other components upward by 90 degrees to a vertical state in the third slider 21. The mounting seat 23 itself is controlled to rotate with the fifth electric telescopic rod 22 as the center of the circle, so that the multiple nozzles 19 are now facing the feeding box 3, and before the push plate 11 pushes the soil blocks, the multiple nozzles 19 spray a certain amount of water on the surface of the soil blocks, so that the dry soil blocks are easily crushed in the subsequent squeezing process of the push plate 11 and the first filter plate 13; and after the soil blocks are crushed, a large amount of dust will overflow from the top of the feeding box 3. At this time, the multiple nozzles 19 can also be used to remove the dust by spraying to prevent the dust from affecting the surrounding air quality.

[0047] At the same time, after the push plate 11 and the first filter plate 13 have crushed the soil blocks once, the debris mixed in the soil blocks remains on the top of the second filter plate 12 and slides from the inclined part of the top of the second filter plate 12 to the horizontal part to accumulate. At this time, the mounting seat 23 and other components can be controlled to reset to Figure 1 The state shown is then controlled, and the sliding plate 15 at the bottom of the feeding box 3 is moved and opened, and the bottom of the second filter plate 12 is no longer blocked. By starting the fan 8 and blowing air toward the second filter plate 12, the lightweight debris accumulated on the top of the second filter plate 12 is blown out to the inside of the feeding box 3, thereby realizing automatic classification of different types of debris; and when there is no need to use the fan 8 to blow the debris inside the feeding box 3, the third slider 21 can be controlled to drive the mounting seat 23 and other components to move together in the second circular groove 20 to the bottom of the first motor 6, and the fan 8 is used to blow air upward toward the first motor 6, so as to facilitate the heat dissipation of the first motor 6 that has been working for a long time and improve the working efficiency of the first motor 6.

[0048] After the sieved soil is introduced into the seedling tray placed in the bottom of the crushing box 2, the two sealing plates 30 can be controlled to block the discharge port, and the extension ends of the two third electric telescopic rods 37 are controlled to extend downward to drive the two moving plates 14 and the sieve plate 32 to move downward, and then drive the plurality of round rods 40 at the bottom of the sieve plate 32 to extend into the seedling tray, and the sieve plate 32 and the plurality of round rods 40 are driven by the cam 34 to move back and forth in the seedling tray, which can scatter and flatten the soil filled in the seedling tray, so that the soil filled in the seedling tray is more uniform and flat; and at this time, the circular ring 7 and the dust removal mechanism and other components are located at the bottom of the crushing box 2, the rotating block can be controlled to drive the fifth electric telescopic rod 22 and the mounting seat 23 and other components to rotate downward by 90 degrees, and then the extension end of the fifth electric telescopic rod 22 is controlled to extend downward and push the protruding part 25 at the bottom of the mounting seat 23 to be inserted into the slot 38 opened at one end of one of the moving plates 14, and then the extension end of the fourth electric telescopic rod 33 is controlled to retract upward to drive the cam 34 to move above the fixed rod 36, and after the electromagnet in the first circular groove 31 is controlled to be de-energized, the third sliding block 21 can be moved in the second circular groove 20 while synchronously driving the two first sliding blocks 35 to rotate in the first circular groove 31, and then the sieve plate 32 in the seedling tray can be synchronously rotated, so that the plurality of round rods 40 can more uniformly scatter and flatten the soil in the seedling tray.

[0049] When the discharge port is blocked, the soil in the crushing box 2 cannot be quickly discharged downward into the sieve plate 32, the fourth electric telescopic rod 33 can be controlled to retract upward after the two sealing plates 30 are opened, the cam 34 is moved into the discharge port, the rotating rod and the fourth electric telescopic rod 33 are driven by the second motor 28 to rotate, the cam 34 is synchronously rotated in the blocked position, and the extension end of the fourth electric telescopic rod 33 is reciprocatingly retracted to drive the rotating cam 34 to synchronously retract, so that the blocked discharge port can be dredged, and the efficiency of soil discharge is improved.

[0050] Moreover, since the plurality of round rods 40 are arranged at the bottom of the sieve plate 32, the plurality of round rods 40 have a certain blocking effect on the falling soil at the bottom of the sieve plate 32 during the sieving and downward discharging of the sieve plate 32, so that the soil sieved by the sieve plate 32 can be more accurately dropped into the seedling tray, and the accuracy of soil filling into the seedling tray is improved; and before the sieve plate 32 sieves the soil, the plurality of nozzles 19 can be controlled to spray water on the surfaces of the plurality of round rods 40, so that the dust generated below the sieve plate 32 during the subsequent sieving of the sieve plate 32 can be adsorbed by the water attached to the surfaces of the plurality of round rods 40, the overflow of dust during the soil filling process is reduced, and the pollution of the surrounding environment by the dust is reduced.

[0051] After the soil in the seedling tray is flattened, the plurality of nozzles 19 can be controlled to face the discharge port, at which time the water sprayed by the plurality of nozzles 19 can be sprayed in the interior of the seedling tray to pre-wet the soil filled in the interior of the seedling tray. After the soil in the interior of the seedling tray is wetted, the thickness of the soil in the interior of the seedling tray is reduced, and a certain amount of soil filled in the interior of the seedling tray can be continuously discharged downward through the discharge port, so that the seedling tray can be filled with enough soil, and the problem that the thickness of the soil is thinned after the seedling tray is filled with soil and is subjected to watering and the soil needs to be continuously added, thereby increasing the labor of the staff, is avoided.

[0052] At the same time, after the seedling tray is filled with enough soil, the extension ends of the two third electric telescopic rods 37 can be controlled to extend downward to drive the two moving plates 14 and the sieve plate 32 to move downward, so that the plurality of round rods 40 at the bottom of the sieve plate 32 can be inserted into the soil containing water again, so that the soil has holes with the same diameter, which facilitates the staff to put the rice seeds into the holes in which the round rods 40 are inserted, and improves the efficiency of rice seedling raising.

[0053] After the equipment is used, the second sliding block can be controlled to drive the circular ring 7 and the plurality of components provided at the top of the circular ring 7 to move to the bottom of the crushing box 2, and the plurality of nozzles 19 can be controlled to spray water toward the sieve plate 32, so that the dust attached to the surfaces of the sieve plate 32 and the round rods 40 can be cleaned. The circular ring 7 can also be controlled to move upward, so that the plurality of nozzles 19 can spray water upward and toward the surfaces of the crushing box 2 and the feeding box 3, so that the dust attached to the surfaces of the crushing box 2 and the feeding box 3 and the surfaces of the first filter plate 13 and the second filter plate 12 can be cleaned. After the dust on the surfaces of the entire equipment is cleaned, the mounting seat 23 can be controlled to rotate by itself to drive the fan 8 to rotate to a position close to the surfaces of the equipment, and the above steps can be repeated, so that the air outlet of the fan 8 can accelerate the drying of the surfaces of the entire equipment, thereby facilitating the storage and use of the equipment.
