[0023] A trapezoidal collection box 2 has a screening box 3 welded to its top. One side of the top of the screening box 3 is provided with a rectangular feed inlet 4. In the middle of the trapezoidal collection box 2, a first screening plate 8 is welded. At the bottom of the trapezoidal collection box 2, a second screening plate 10 is welded. The longitudinal cross-sectional shapes of both the first screening plate 8 and the second screening plate 10 are "Z" - shaped (the first screening plate 8 is a vertical "Z" - shape, and the second screening plate 10 is a "Z" - shape that spreads outwards). One side of the top of the first screening plate 8 is equidistantly provided with first filtering holes 9, and one side of the top of the second screening plate 10 is equidistantly provided with second filtering holes 11. The aperture of the first filtering holes 9 is larger than that of the second filtering holes 11, which is convenient for the device to screen rice of different sizes. At the top of one end of the screening box 3, there is a discharge opening 12. Inside the discharge opening 12, a first baffle 13 is hingedly installed. At the top of one end of the trapezoidal collection box 2, a second baffle 14 is hingedly installed through a hinge. The use of the second baffle 14 can cover the area above the second screening plate 10. At the bottom of one end of the trapezoidal collection box 2, a third baffle 15 is hingedly installed through a hinge. On one side of the first baffle 13, one side of the second baffle 14, and one side of the third baffle 15, a U - shaped clamping block 16 is welded. At the position of the U - shaped clamping block 16 welded to the first baffle 13 on one side of the screening box 3, at the position of the U - shaped clamping block 16 welded to the second baffle 14 on the top of one side of the trapezoidal collection box 2, and at the position of the U - shaped clamping block 16 welded to the third baffle 15 on the bottom of one side of the trapezoidal collection box 2, a U - shaped fixing block 17 is welded.

The vibration motor 7 works to drive the trapezoidal collection box 2 to vibrate vertically along its inclined plane (which is convenient for the movement of rice inside the device). The first screening plate 8 and the second screening plate 10 vibrate synchronously with the trapezoidal collection box 2. After the vibration motor 7 runs stably, the staff pours the rice into the device through the rectangular feed inlet 4. When the rice contacts the first screening plate 8, the rice can be vibration - screened. The broken rice in the rice falls through the first screening plate 8 and contacts the second screening plate 10. Through the use of the second screening plate 10, the screened rice can be screened again. The rice after re - screening falls through the second screening plate 10 and contacts the bottom of the trapezoidal collection box 2. With the continuous vibration of the device, the rice gradually moves closer to the other side of the device;
[0025] After the device is used, the staff opens the No. 1 baffle 13 to collect the rice that meets the standards, opens the No. 2 baffle 14 to collect the inferior rice, and opens the No. 3 baffle 15 to collect the broken rice, so as to facilitate the staff to use the device.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
