Qualified repair fertilizer material will naturally fall into the collecting machine box for collection. At the same time, when the rotating shaft is passively rotated, it will also drive the meshing transmission component to rotate synchronously, thereby driving the corresponding screw to rotate. The two rotating screws can jointly drive the circular arc brush plate to translate, and the circular arc brush plate in horizontal movement can sweep the screening mesh plate that is closely connected, thereby cleaning the sieve holes on the screening mesh plate.

[0017] When the screw rod is passively rotated, the cam 1 connected with the thread will be driven to rotate synchronously, and the cam 1 will be driven to rotate and translate on the screw rod during the translation process of the arc brush plate, thereby contacting and pushing the inclined plate on the rotating rod, and synchronously driving the rotating rod and the torsion springs installed on both sides of the rotating rod to rotate at a certain angle, and the passively inclined inclined plate will drive the two connected vibration ball plates to move in the sleeve rod. It is worth mentioning that a section of the plate body in the cam 1 that contacts the inclined plate is specifically made of natural rubber material, so when the cam 1 is passively rotated 90 When the ball passes through the arc groove, it will separate from the inclined plate in contact because of a section of rubber material. That is, the inclined plate, which is no longer subjected to force and tilted in the opposite direction, will be immediately reset by the two deformed torsion springs, thereby driving the two vibration ball plates to reset, and then the two passively moving vibration ball plates will make a brief and powerful contact and hit the surface of the screen mesh plate, producing a vibration effect on the screen mesh plate.

[0034] Each of the vibration structures includes a cam 27 threadedly connected to the screw rod 22.

[0035] The above scheme is adopted: when the screw rod 22 rotates passively, it will also drive the threaded cam 27 to rotate synchronously, and in the translation process of the arc brush plate 25, it will also push the cam 27 to rotate and translate on the screw rod 22, thereby contacting and pushing the inclined plate 232 on the rotating rod 230, and synchronously driving the rotating rod 230 and the torsion springs 231 installed on both sides of the rotating rod 230 to rotate at a certain angle, and the passively inclined inclined plate 232 will drive the two connected vibration ball plates 233 to guide and move in the sleeve rod 235. It is worth mentioning that a section of the plate body in the cam 27 that contacts the inclined plate 232 is specifically made of natural rubber material, so when the cam When one 27 passively rotates 90 degrees and passes through the arc groove 26, it will separate from the contacting inclined plate 232 because of a section of rubber material. That is, the inclined plate 232, which is no longer subjected to force and tilted in the opposite direction, will be immediately reset by the two deformed torsion springs 231, thereby driving the two vibrating ball plates 233 to reset, and then the two passively moving vibrating ball plates 233 will make a brief and powerful contact and hit the surface of the sieve plate 13, producing a vibration effect on the sieve plate 13. Through the vibration, some materials that may be stuck in the sieve holes of the sieve plate 13 can be discharged to avoid continuous clogging of the sieve holes. The above can achieve a secondary through-hole effect on the sieve holes of the sieve plate 13.

[0036] Each rotary lifting structure includes a cylindrical rod 236 fixedly connected to the other end of the screw rod 22, and a clamping block 237 is fixedly connected to the outer wall of both ends of the cylindrical rod 236.

The cylindrical rod 236 and the inner wall of one end of the sliding rod 238 are rotatably connected, and the two clamping blocks 237 can intermittently fit and rotate with the inner wall of the annular groove 239. The two clamping blocks 237 can intermittently fit and engage with the inner walls of the two clamping grooves 240 respectively, a cam 241 is fixedly connected to the rod body of the sliding rod 238, and a semicircular bracket 242 can be intermittently fit and engage with the outer wall of the bottom end of the cam 241, and a guard plate 243 is provided on the bottom end of the semicircular bracket 242, and the outer wall of one end of the guard plate 243 is fixedly connected to the outer wall of one end of the solid support plate 24, and a rectangular groove 244 is opened on one side of the top of the guard plate 243, and the bottom end of the semicircular bracket 242 and the inner wall of the rectangular groove 244 are fit and slidably connected.

[0037] By adopting the above scheme: the semicircular bracket 242 is manually clamped on the bottom end of the cam 241 in advance, the rotating screw 22 will synchronously drive the cylindrical rod 236 and the two clamping blocks 237 to rotate in the annular groove 239 and the two clamping grooves 240 in the sliding rod 238 respectively, and the semicircular bracket 242 is manually pushed to translate in the rectangular groove 244, and the T-shaped clamping plate 246 installed on the semicircular bracket 242 is clamped into the T-shaped groove 245 at one end of the rectangular groove 244.

A pressure rod 247 can be intermittently fitted and connected to the outer wall on one side of the bottom end of the cam 241.

An inclined ear plate 249 is fixedly connected to the bottom end of the pressure rod 247, and a multi-sheet material plug 250 is fixedly connected to the other end of the inclined ear plate 249. The multi-sheet material plug 250 can be intermittently and tightly clamped with the inner wall of each discharge port.

[0039] By adopting the above scheme: the offset semicircular bracket 242 can no longer limit the cam 241, and the sliding rod 238 and the cam 241 will rotate synchronously with the rotation of the screw 22, thereby the cam 241 will drive the pressure rod 247 to move downward in the limiting square plate 248, and the downward pressure rod 247 can drive the inclined ear plate 249 and the connected multi-sheet plug 250 to move downward synchronously, thereby driving the multi-sheet plug 250 to disengage from the corresponding card-connected discharge port, so that the materials collected and screened in the receiving box 1 can be discharged uniformly, thereby improving production efficiency.

[0040] The working principle and use process of the present invention are as follows: by taking out the sealing cover 14 in the inner wall at one end of the sieve plate 13, the material to be sieved can be put into the sieve plate 13, and then after the sealing cover 14 is blocked again for the sieve plate 13 by the staff, the motor 11 is started to drive the rotating shaft 12 and the sieve plate 13 to rotate synchronously, so that the repair fertilizer material in the sieve plate 13 can be rotated and screened, and the qualified repair fertilizer material will naturally fall into the collecting machine box 1 for collection. At the same time, when the rotating shaft 12 is passively rotated, it will also drive the meshing transmission component 21 to rotate synchronously, thereby driving the corresponding screw 22 to rotate. The two rotating screws 22 can jointly drive the circular arc brush plate 25 to translate, and the circular arc brush plate 25 in horizontal movement can sweep the sieve plate 13 connected to the sieve plate 13, so as to clean the sieve holes on the sieve plate 13, and the contact between the rotating sieve plate 13 and the translated circular arc brush plate 25 can greatly improve the effect and efficiency of hole cleaning. At the same time, when the screw 22 is passively rotated, it will also drive the threaded cam 27 to rotate synchronously, and the translation process of the circular arc brush plate 25 will also push the cam 27 to rotate and translate on the screw 22, and the cam 27 that has been rotated and moved will contact and push the rotating rod 2 The inclined plate 232 on the cam 27 is passively tilted, and the inclined plate 232 will synchronously drive the rotating rod 230 and the torsion springs 231 installed on both sides of the rotating rod 230 to rotate at a certain angle, so that the two torsion springs 231 are deformed on the corresponding arc plates 29, and the passively tilted inclined plate 232 will drive the two connected vibration ball plates 233 to move in the sleeve rod 235. It is worth mentioning that a section of the plate body in the cam 27 that contacts the inclined plate 232 is specifically made of natural rubber material, so when the cam 27 is passively rotated 90 degrees through the arc groove 26, it will be because of the section of the rubber material of the plate body itself to contact with the connecting ball plate 233. The contacted inclined plate 232 is separated without affecting the normal passive rotation of the cam 27. That is, the inclined plate 232, which is no longer subjected to force and produces a reverse tilt, will be immediately driven to reset by the two deformed torsion springs 231, thereby driving the two vibrating ball plates 233 to reset, and then the two passively moving vibrating ball plates 233 will make a brief and powerful contact and hit the surface of the sieve plate 13, generating a vibration effect on the sieve plate 13, and the vibration can make some materials that may be stuck in the sieve holes of the sieve plate 13 be discharged to avoid continuous clogging of the sieve holes, so as to achieve a secondary through-hole effect on the sieve holes of the sieve plate 13, thereby greatly improving the screening efficiency of the repair fertilizer;

[0041] At the same time, during the passive rotation of the screw 22, the semicircular bracket 242 is manually connected to the bottom end of the cam 241 in advance, so that the rotating screw 22 will synchronously drive the cylindrical rod 236 and the two blocks 237 to rotate in the annular groove 239 and the two grooves 240 in the slide bar 238 respectively. When the arc brush plate 25 is passively swept to the position where the sealing cover 14 is located in the sieve plate 13, the semicircular bracket 242 can be manually pushed to translate in the rectangular groove 244, and the T-shaped clamping plate 246 installed on the semicircular bracket 242 is connected to the T-shaped groove 245 at one end of the rectangular groove 244. That is, the offset semicircular bracket 242 can no longer limit the cam 241, and the slide bar 238 and the cam 241 will rotate synchronously with the rotation of the screw rod 22, thereby the cam 241 will drive the pressure rod 247 to move downward in the limiting square plate 248, and the downward pressure rod 247 can drive the inclined ear plate 249 and the connected multi-sheet plug 250 to move downward synchronously, thereby driving the multi-sheet plug 250 to disengage from the corresponding card-connected discharge port, so that the materials collected and screened in the receiving machine box 1 can be discharged uniformly, avoiding manual removal and plugging of the multi-sheet plug 250 in the discharge port, thereby improving production efficiency.
