[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the starting motor drives the screw to rotate, and the screw drives the movable frame to reciprocate left and right on the box body, and the movable frame also drives the crushing roller to move synchronously, and the movable frame drives the material box, the guide rod 1, the connecting frame, and the sealing plate to move synchronously left and right. The connecting frame will be blocked by the inclined block plate, and then the connecting frame will drive the sealing plate to slide upward on the guide rod 1, compressing the spring 1, and then the feeding port will be opened, and the fertilizer in the material box will fall from the feeding port onto the screen plate. When the connecting frame is separated from the inclined block plate, it will reset under the action of the spring 1, and the feeding port will be blocked again. The automatic intermittent feeding method reduces the one-time large-scale feeding, which causes a large amount of fertilizer to accumulate at a certain place of the screen plate, affecting the subsequent crushing quality. The provided crushing roller is convenient for crushing the block fertilizer on the screen plate, and it falls to the lower side of the box body through the screen plate, thereby avoiding the influence of large blocks on subsequent mixing.

[0017] 2. In the present invention, when the sealing plate moves upward, it will also drive the second rack to move upward synchronously, the second rack drives the gear shaft to rotate, the gear shaft drives the first rack to slide downward on the support frame, and the first rack simultaneously drives the rotating shaft and the auxiliary grinding plate to move downward synchronously, which is beneficial to the auxiliary crushing of the block fertilizer dropped from the discharge port onto the screen plate, thereby improving the crushing quality of the subsequent crushing roller; when the rotating shaft moves downward, it will also drive the connecting rod to move downward synchronously, and the connecting rod is blocked by the protrusion, which will drive the rotating shaft and the auxiliary grinding plate to rotate on the first rack, compressing the torsion spring, thereby improving the fertilizer crushing quality of the auxiliary grinding plate; at the same time, the self-rotating auxiliary grinding plate is also beneficial to push the small block fertilizer that can be sieved after crushing to the sieve holes on the sieve plate, so that it can accelerate the screening, reducing the accumulation of a large amount of fertilizer on the sieve plate, causing the sieve plate to be blocked.

[0018] 3. In the present invention, when the crushing roller moves to the left, it will contact with the protective scraper and push the protective scraper to move outward. The protective scraper can easily scrape off the fertilizer debris adhering to the surface of the rolling crushing roller, thereby reducing the fertilizer adhering to the crushing roller for a long time, causing fertilizer waste and deterioration, and also improving the crushing quality of the fertilizer on the screen plate by the crushing roller.

[0019] 4. In the present invention, when the protective scraper moves outward, it will also drive the pressure plate and the guide rod 2 to move outward synchronously, compressing the spring 2 and the hollow rubber bag. The gas in the hollow rubber bag is ejected from the nozzle tube, which is beneficial to blowing the fertilizer accumulated on the left and right sides of the upper end of the screen plate to the middle of the screen plate, so that the fertilizer can be crushed by the crushing roller, reducing the situation that the fertilizer on the left and right sides of the screen plate cannot be crushed by the crushing roller. At the same time, the protective scraper set can also reduce the situation that the fertilizer splashes outward when the nozzle tube blows the fertilizer on the left and right sides of the screen plate, ensuring neatness and saving the cost of fertilizer. When the material box moves to the right, the protrusion will contact and squeeze the protective scraper on the right side. At this time, the protective scraper on the right side will not contact the crushing roller, but will only prevent the fertilizer from splashing outward. In addition, a heating strip is provided inside the crushing roller, which can evaporate the moisture in the fertilizer adhering to the surface of the crushing roller and the upper end of the screen plate, reducing the situation that the fertilizer adheres to the crushing roller and the screen plate and cannot fall off and is blocked by screening.

[0020] 5. In the present invention, when the guide rod 2 moves outward, it will also drive the magnetic block to move outward synchronously. When the magnetic block passes the upper side of the magnetic plate, it will generate magnetic repulsion on the magnetic plate, pushing the magnetic plate and the knocking plate to slide downward on the box body, compressing the spring 3. When the magnetic block moves away from the upper side of the magnetic plate, under the action of the spring 3, the knocking plate and the magnetic plate are pushed to reset, and the knocking plate will knock on the screen plate, which is conducive to shaking off the fertilizer blocked in the sieve holes of the screen plate, ensuring the screening quality of the fertilizer, and reducing the blockage of the screen plate, thereby improving the crushing quality and efficiency of the fertilizer.

The ends of the guide rods 27 that are away from each other penetrate through the sliding installations on both sides. On the fixed plate 25, springs 28 are sleeved on the outer sides of the guide rods 27, and protective scrapers 29 are fixedly installed on the lower sides of the ends of the pressure plates 26 that are close to each other.
