[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 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. The movable frame also drives the crushing roller to move synchronously, and the movable frame drives the material box, guide rod 1, connecting frame, and sealing plate to move left and right synchronously. The connecting frame will be blocked by the inclined block plate, and then push the connecting frame to drive the sealing plate to slide upward on the guide rod 1, compressing the spring 1. At this time, the discharge port is opened, and the fertilizer in the material box will fall from the discharge port onto the screen plate. When the connecting frame is separated from the inclined block plate, it is reset under the action of the spring 1, and the discharge port is blocked again. The automatic intermittent discharge method reduces the one-time large-scale discharge, which causes a large amount of fertilizer to accumulate at a certain place on the screen plate, affecting the subsequent crushing quality. The provided crushing roller is convenient for crushing the block fertilizer on the screen plate and dropping it to the lower side of the box through the screen plate, thereby avoiding the influence of large blocks on subsequent mixing.

[0021] 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 synchronously 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 will be 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.

[0022] 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, reducing the fertilizer from 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.

[0023] 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 will be ejected from the nozzle tube, which is conducive 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 provided can also reduce the situation that the fertilizer is splashed outward when the nozzle tube blows the fertilizer on the left and right sides of the screen plate, ensuring neatness and saving fertilizer costs. 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 the screening.

[0024] 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 generates a magnetic repulsive force 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.

At the same time, the self-rotating auxiliary grinding plate 14 is also beneficial to push the small block fertilizer that can be sieved after crushing to the sieve hole on the sieve plate 2, so that it can accelerate the screening, reducing a large amount of fertilizer accumulation on the sieve plate 2 and causing the sieve plate 2 to be blocked.

[0038] As an embodiment of the present invention, a screening mechanism is further provided for allowing the crushed fertilizer to pass through the sieve plate 2. The screening mechanism includes nozzle tubes 23 arranged on the left and right sides of the inside of the sieve plate 2. The ends of the nozzle tubes 23 that are away from each other are connected through connecting tubes and are provided with hollow rubber bags 24. The ends of the hollow rubber bags 24 that are away from each other are fixedly installed with fixing plates 25. The fixing plates 25 are respectively fixedly connected to the left and right ends of the sieve plate 2. The ends of the hollow rubber bags 24 that are close to each other are fixedly installed with pressure plates 26. The ends of the pressure plates 26 that are away from each other are symmetrically fixed with guide rods 27. The ends of the guide rods 27 that are away from each other are respectively penetrated and slidably installed on both sides. On the fixed plate 25, the outer side of the guide rod 27 is sleeved with a spring 28, and the lower side of the end of the pressure plate 26 that is close to each other is fixedly installed with a protective scraper 29, and the lower end of the protective scraper 29 is in contact with the upper end of the sieve plate 2.

[0040] Working principle:

[0041] When the present invention is used, the starting motor 6 drives the screw 5 to rotate, and the screw 5 drives the movable frame 4 to reciprocate left and right on the box body 1. The movable frame 4 also drives the crushing roller 3 to move synchronously, and the movable frame 4 drives the material box 7, the guide rod 11, the connecting frame 10, and the closing plate 9 to move left and right synchronously. The connecting frame 10 will be blocked by the inclined block plate 13, and then push the connecting frame 10 to drive the closing plate 9 to slide upward on the guide rod 11, compressing the spring 12, and then the discharge port 8 will be opened, and the fertilizer in the material box 7 will fall from the discharge port 8 onto the screen plate 2. When the connecting frame 10 is separated from the inclined block plate 13, it is reset under the action of the spring 12, and the discharge port 8 is blocked again. The automatic intermittent discharge method reduces the one-time large-scale discharge, which causes a large amount of fertilizer to accumulate on the screen. The crushing roller 3 is convenient for crushing the fertilizer block on the screen plate 2 and dropping it to the lower side of the box body 1 through the screen plate 2, thereby avoiding the influence of large blocks on the subsequent mixing. When the sealing plate 9 moves upward, it will also drive the rack 2 16 to move upward synchronously, and the rack 2 16 drives the gear shaft 17 to rotate. The gear shaft 17 drives the rack 15 to slide downward on the support frame 18. The rack 15 synchronously drives the rotating shaft 19 and the auxiliary grinding plate 14 to move downward synchronously, which is beneficial to the auxiliary crushing of the fertilizer block dropped from the discharge port 8 onto the screen plate 2, thereby improving the crushing quality of the subsequent crushing roller 3. When the rotating shaft 19 moves downward, it will also drive the connecting rod 21 to move downward synchronously. The connecting rod 21 is affected by the protrusion 22 The blocking will drive the rotating shaft 19 and the auxiliary grinding plate 14 to rotate on the rack 15, compressing the torsion spring 20, thereby improving the fertilizer crushing quality of the auxiliary grinding plate 14. At the same time, the self-rotating auxiliary grinding plate 14 is also conducive to pushing the small pieces of fertilizer that can be sieved after crushing to the sieve holes on the screen plate 2, so that it can accelerate the screening, reducing a large amount of fertilizer accumulation on the screen plate 2, causing the screen plate 2 to be blocked. When the crushing roller 3 moves to the left, it will contact with the protective scraper 29 and push the protective scraper 29 to move outward. The protective scraper 29 is convenient for scraping off the fertilizer debris adhering to the surface of the rolling crushing roller 3, reducing the fertilizer from adhering to the crushing roller 3 for a long time, causing fertilizer waste and deterioration, and also improving the crushing of the fertilizer on the screen plate 2 by the crushing roller 3. Quality, when the protective scraper 29 moves outward, it will also drive the pressure plate 26 and the guide rod 27 to move outward synchronously, compressing the spring 28 and the hollow rubber bag 24. The gas in the hollow rubber bag 24 is ejected from the nozzle tube 23, which is conducive to blowing the fertilizer accumulated on the left and right sides of the upper end of the sieve plate 2 to the middle of the sieve plate 2, so that the fertilizer can be crushed by the crushing roller 3, reducing the situation where the fertilizer on the left and right sides of the sieve plate 2 cannot be crushed by the crushing roller 3. At the same time, the protective scraper 29 provided can also reduce the situation where the fertilizer splashes outward when the nozzle tube 23 blows the fertilizer on the left and right sides of the sieve plate 2, ensuring cleanliness and saving fertilizer costs. When the material box 7 moves to the right, the protrusion 22 will contact and squeeze the protective scraper 29 on the right side.At this time, the protective scraper 29 on the right side does not contact the crushing roller 3, but only plays a role in preventing the fertilizer from splashing outward. In addition, a heating strip is provided inside the crushing roller 3, which can evaporate the moisture in the fertilizer adhering to the surface of the crushing roller 3 and the upper end of the sieve plate 2, thereby reducing the situation where the fertilizer cannot fall off and is blocked during screening. When the guide rod 27 moves outward, it also drives the magnetic block 33 to move outward synchronously. When the magnetic block 33 passes the upper side of the magnetic plate 32, it Plate 32 generates a magnetic repulsive force, pushing the magnetic plate 32 and the knocking plate 30 downward on the box body 1, compressing spring three 31. When the magnet 33 moves away from the upper side of the magnetic plate 32, the spring three 31 pushes the knocking plate 30 and the magnetic plate 32 back to their original position. The knocking plate 30 knocks against the sieve plate 2, which helps to shake off the fertilizer stuck in the sieve holes of the sieve plate 2. This ensures the quality of the fertilizer screening and reduces the blockage of the sieve plate 2, thereby improving the quality and efficiency of the fertilizer crushing process.
