Then, during the rotation process of the second driving wheel 46, the second belt 48 is driven to start moving, and the second driven wheel 49 is driven to start rotating, so that the second driven wheel 49 also drives the driving gear 57 to rotate together.
Finally, when the driving motor 41 is running, the reciprocating rod 63 and the rotating disc 52 move simultaneously, so that the first screen 3 and the second screen 61 can keep good screening effect, not only can the first screen 3 and the second screen 61 be prevented from being blocked at the same time, but also the screening smoothness can be kept, and further the screening efficiency can be increased.
The application method and the working principle of the device are as follows: firstly, the finished product after rice processing is poured into the feed inlet 13, so that the material is piled up on the surface of the second screen 61, and at this time, the material contains dust, impurities, rice hulls and rice, so that the rice and the rice hulls are separated by using meshes on the surface of the second screen 61, and then the rice is screened according to different sizes by the second screen 3, in the screening process, the driving motor 41 starts to operate, the first driving wheel 42 is driven to start rotating, the first belt 47 is driven to start moving, the first driven wheel 43 starts rotating, and then the first rotating rod 45 also starts rotating, therefore, when the first rotating rod 45 rotates, the rotating plate 62 at one end is driven to rotate together, and at the same time, the second driving wheel 46 at the other end is also driven to start rotating.
Then, during the rotation process of the second driving wheel 46, the second belt 48 is driven to start moving, and the second driven wheel 49 is driven to start rotating, so that the second driven wheel 49 also drives the driving gear 57 to rotate.
Therefore, when the driving gear 57 rotates, the driven gear 58 is driven to rotate together to drive the rotating disc 52 to rotate, so that the pushing rod 53 on the surface of the rotating disc 52 starts to perform circular motion, and the pushing rod 53 drives the moving rod 54 to move while moving, and because one side of the moving rod 54 is fixedly connected with the power rod 55, the power rod 55 can only perform linear motion under the action of the limiting frame 56, and therefore, the moving rod 54 can only perform linear reciprocating motion under the driving of the pushing rod 53, so that the power rod 55 reciprocates up and down.
In the moving process, the power rod 55 gradually approaches the stress plate 31 and then moves away from the stress plate 31 to reciprocate along the track, and in the moving process, the power rod 55 can strike the stress plate 31, so that the first screen 3 can move downwards. However, when the first screen 3 is forced to move downwards, the four brackets 91 are driven to move together, and the brackets 91 can squeeze the springs 93 when moving, so when the power rod 55 is far away, the springs 93 start to reset, and the first screen 3 can also be driven to reset, so that the first screen 3 is in the process of jumping once, the first screen 3 is jumped for a plurality of times, the rice with blocked surface meshes can be ejected, and the condition of reduced screening efficiency caused by blockage is avoided.
In the rotating process of the rotating plate 62, the connecting end of the reciprocating rod 63 and the rotating plate 62 can move along the rotating plate 62 in a circular way, so that the other end of the reciprocating rod 63 can control the second screen 61 to start reciprocating movement through the connecting piece 64, the screening efficiency of the second screen 61 is improved, rice and rice hulls can be prevented from being accumulated on the surface of the second screen 61, the surface of the second screen 61 can be prevented from being blocked, and in the process, the guide block 66 can slide along the surface of the sliding rail 65 to limit the movement track of the second screen 61;
finally, the finished product after the rice processing also can produce the raise dust when pouring into, and second screen cloth 61 also can produce the raise dust when reciprocating motion sieves, axial fan 15 begins the motion this moment, can blow dust and some rice husk to the dirt outlet 16 to reach the effect of separation rice husk, some straw rice husk can pile up on second screen cloth 61 surface, and qualified rice can flow from the first screen cloth 3 one end that the slope set up, and some less, unqualified and broken rice can pile up inside the recovery tank 21.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
