The working principle is as follows: when broken rice in the rice is screened, the motor 701 drives the rotating block 702 to rotate, a clamping block 705 is arranged in a clamping cavity 704 formed in the rotating block 702, since the top of the extension spring 706 is fixedly connected with the bottom of the transmission shaft 703, and the extension spring 706 is continuously in a stretched state, so that the friction force exists between the top of the rotating block 702 and the bottom of the transmission shaft 703, and the transmission shaft 703 is driven to rotate under the action of the friction force, then the centrifugal concave block 2 fixedly connected with the top is driven to rotate, then the rice to be screened is guided into the surface of the centrifugal concave block 2 in the box body 1, under the effect of centrifugal force, normal rice strikes sieve 3 with garrulous rice, and later garrulous rice can reach the opposite side of sieve 3 through the filtration pore of sieve 3, drops baffle 4's surface, flows out through seting up the hole in the 1 side of box adjacent with baffle 4 afterwards.
In this in-process, vibrate wheel 5 and rotate continuously, the arch of its side constantly strikes sieve 3, under supporting spring 6's effect, and sieve 3 can be controlled and vibrate, has avoided garrulous rice to block up sieve 3, and when the most advanced of normal rice inserted sieve 3 filter the downthehole portion and can't drop, explains that rice centrifugal force is too big, and the degree that the rice inserted filter the hole is darker.
The sieve plate 3 drives the cam 710 to rotate through the linkage rod 711, and the bulge part of the cam 710 is not contacted with the bottom of the receiving plate 709 initially, so that a gap exists between the bulge part and the bottom of the receiving plate 709, so that the bulge part on the side surface of the cam 710 cannot press the receiving plate 709, when normal rice is inserted into the filtering holes on the surface of the sieve plate 3, the weight of the sieve plate 3 is increased, the inertia force is increased after the normal rice is impacted by the oscillating wheel 5, the moving amplitude of the sieve plate 3 is increased, the linkage rod 711 is driven to further move, and the bulge part on the side surface of the cam 710 can press the receiving plate 709.
Because the friction block 707 is initially connected with the limit toothed plate 713 through the spring and has friction with the transmission shaft 703, the receiving plate 709 is pressed to further press the side surface of the transmission shaft 703 through the buffer spring 708, the ratchet rod 712 synchronously moves along with the receiving plate 709, and the ratchet rod 712 is meshed with the limit toothed plate 713 in a direction away from the transmission shaft 703 in one direction, so that the reset after the receiving plate 709 moves is avoided, the resistance to the rotation of the transmission shaft 703 is increased, the rotation speed of the transmission shaft 703 is reduced, the centrifugal force of the rice is reduced, the force of the rice impacting the sieve plate 3 is reduced, when the rice is continuously inserted into the filtering hole, the insertion degree is reduced, the rice can fall off through the vibration of the sieve plate 3, the rice is prevented from being continuously inserted into the filtering hole of the sieve plate 3 and cannot fall off, and the rice cannot be continuously blocked in the filtering hole of the sieve plate 3, thereby when having reached the broken rice in the screening rice, avoided the most advanced effect that influences the screening process that inserts in the filtration pore of screening board of a large amount of normal rice.
When the rice is screened, when the rotating speed of the centrifugal concave block 2 is reduced, it is indicated that part of the normal rice is inserted into the filtering holes of the sieve plate 3, a user knows through a rotating speed sensor installed inside the centrifugal concave block 2, then the guide rod 804 drives the extrusion air plate 803 to move towards the inner side of the box body 1 inside the air pressure pipe 802, because the air pressure pipe 802 is communicated with the air spring 6 through the guide pipe 801, the air pressure inside the air spring 6 is gradually increased, the extrusion force on the sieve plate 3 is increased, and the speed of the oscillation wheel 5 for extruding the sieve plate 3 is unchanged, so the vibration degree of the sieve plate 3 is increased, and the normal rice inserted into the filtering holes on the surface of the sieve plate 3 is vibrated and falls off, thereby the effect that the rice can fall off in the screening process when the rice is inserted into the filtering holes on the surface of the sieve plate 3 is achieved.
