DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-6 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the utility model.

[0027] According to one embodiment of the utility model, Figure 1 and Figure 6 As shown: This embodiment provides a cleaning device 200 of a rice-rough separator 100 screen plate 101, comprising a rice-rough separator 100, a screen plate 101 is obliquely arranged on the inner side wall of the rice-rough separator 100, a discharge port 102 is opened at the lower side of the screen plate 101, a box body 103 is arranged on the outer side wall of the rice-rough separator 100, and a cleaning device 200 is arranged in the box body 103;

[0028] The cleaning device 200 includes a cleaning component 300 and a dust removal component 400. A driving motor 201 is arranged on the outer wall of the box body 103. A screw rod 202 is connected to the output shaft of the driving motor 201. A driving block 203 is sleeved on the screw rod 202. A slide groove 204 is provided on the inner wall of the grain-rough separator 100. A slider 205 is provided on the driving block 203 corresponding to the slide groove 204. An electric telescopic push rod 206 is provided at the bottom of the driving block 203. A fixing seat 207 is connected to the lower side of the electric telescopic push rod 206. A notch 1 208 and a notch 209 are provided at the bottom of the fixing seat 207. A vibration motor 210 is arranged on the inner wall of the grain-rough separator 100. The output end of the vibration motor 210 contacts the sieve plate 101.

[0029] When the grain screening separator has finished working and needs to clean the sieve plate 101 of the grain screening separator, the staff needs to start the vibration motor 210 first. The two motors arranged inside the vibration motor 210 rotate synchronously in opposite directions, so that the output end of the vibration motor 210 generates a reverse exciting force, causing the sieve plate 101 to vibrate. When the sieve plate 101 vibrates, a part of the rough grain residues and rice flour blocked on the sieve plate 101 fall off due to the vibration, and then the drive motor 201 is started. The control unit of the drive motor 201 converts high-voltage direct current into alternating current, which is supplied to the motor through the three-phase power input terminals on the drive motor 201. When the three-phase power is input at each input terminal, a rotating magnetic field is generated in the stator, and at the same time, an induction is generated in the rotor. The current is applied, and the output shaft of the driving motor 201 starts to rotate under the effect of the magnetic field force. A coupling is provided on the output shaft of the driving motor 201, and the output shaft is connected to the screw rod 202 through the coupling. The coupling can facilitate the staff to disassemble and replace the screw rod 202 when the screw rod 202 is damaged, thereby reducing the staff's work difficulty and improving the staff's work efficiency. The output shaft of the driving motor 201 rotates to drive the screw rod 202 to rotate synchronously. The end of the screw rod 202 is arranged between the balls in the groove. The balls can reduce the extrusion force generated when the screw rod 202 rotates, reduce the friction at the end of the screw rod 202, and extend the service life of the screw rod 202. The extrusion force generated when the screw rod 202 rotates drives the driving block 203 to rotate synchronously. The dovetail slider 205 on the driving block 203 moves along the dovetail slot 204. The settings of the dovetail slider 205 and the dovetail slot 204 can ensure the stability of the driving block 203 when it moves, and prevent the driving block 203 from tilting. When the driving block 203 moves, the pipe used to connect the booster nozzle 303 and the suction nozzle 403 in the fixed seat 207 is synchronously extended along with the fixed seat 207, and the electric telescopic push rod 206 on the driving block 203 moves synchronously. The electric telescopic push rod 206 is extended to make the fixed seat 207 close to the sieve plate 101, and then the negative pressure fan 402 is started. The negative pressure fan 402 makes the suction nozzle 403 generate suction, and driven by the driving block 203, part of the residue on the sieve plate 101 is sucked into the sewage storage The booster pump 302 is then started, and the booster pump 302 pressurizes the water in the water tank 301 and sprays it out through the booster nozzle 303, so as to clean the sieve plate 101 for the second time. The sewage after cleaning is discharged from the discharge port 102 along the inner wall of the grain screening separator, and the cleaning of the sieve plate 101 is completed. After the cleaning of the sieve plate 101 is completed, the cleaning component 300 is returned to the box body 103, which does not affect the subsequent use of the grain screening separator. By arranging the cleaning device 200 in the grain-rough separator 100, the staff does not need to remove the sieve plate 101 to clean it, which not only reduces the work content and labor intensity of the staff, but also improves the cleaning efficiency of the sieve plate 101.

[0030] The use of this utility model:

[0031] When the grain screening separator is finished and the sieve plate 101 of the grain screening separator needs to be cleaned, the staff needs to start the vibration motor 210 first. The two motors arranged inside the vibration motor 210 rotate synchronously in opposite directions, so that the output end of the vibration motor 210 generates a reverse exciting force, causing the sieve plate 101 to vibrate. When the sieve plate 101 vibrates, part of the rough grain residues and rice flour blocked on the sieve plate 101 fall off due to the vibration, and then start the drive motor 201. The control unit of the drive motor 201 converts high-voltage direct current into alternating current, and supplies the power to the machine through the three-phase power input terminals on the drive motor 201. When the three-phase power is input at each input end, a rotating magnetic field is generated in the stator, and an induced current is generated in the rotor. Under the action of the magnetic field force, the output shaft of the drive motor 201 starts to rotate, and the rotation of the output shaft of the drive motor 201 drives the screw rod 202 to rotate synchronously. The extrusion force generated when the screw rod 202 rotates drives the drive block 203 to move synchronously, and the drive block 203 The electric telescopic push rod 206 moves synchronously, the electric telescopic push rod 206 extends to make the fixing seat 207 close to the sieve plate 101, and then the negative pressure fan 402 is started, the negative pressure fan 402 makes the suction nozzle 403 generate suction, and part of the residue on the sieve plate 101 is sucked into the dirt storage tank under the drive block 203, and then the booster pump 302 is started, and the booster pump 302 pressurizes the water in the water storage tank 301 and sprays it out through the booster nozzle 303, so as to clean the sieve plate 101 for the second time. The sewage after cleaning is discharged from the discharge port 102 along the inner wall of the grain screening separator, completing the cleaning of the sieve plate 101. After the cleaning of the sieve plate 101 is completed, the cleaning component 300 is returned to the box body 103; by arranging the cleaning device 200 in the grain-rough separator 100, the staff no longer needs to remove the sieve plate 101 to clean it, which not only reduces the work content and labor intensity of the staff, but also improves the cleaning efficiency of the sieve plate 101.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
