In the technical scheme of the application, rapeseeds to be screened enter the particle size screening box 110 and firstly fall on the coarse separation plate 110, and particles with the particle size smaller than the sieve pores of the coarse separation plate 110 pass through the coarse separation plate 110 and fall on the fine separation plate 120; particles having a particle size larger than the sieve holes of the coarse separator plate 110 slide down from the surface of the coarse separator plate 110 and are discharged from the second discharge hole 142. Among the particles falling on the fine classification plate 120, particles having a particle size larger than the mesh opening of the fine classification plate 110 slide down from the top surface of the fine classification plate 110 and enter the duct 300 from the first discharge port 141; particles having a particle size smaller than the mesh of the fine classification plate 110 pass through the fine classification plate 120, fall on the guide plate 130, and are discharged by sliding from the surface of the guide plate 130 into the second discharge hole 142. Through the screening of the grain size screening box 100, rapeseeds which do not meet the grain size requirement are removed together with large-volume impurities. The particles entering the duct 300 enter the chambers of the core 220 from the weep holes 310 and follow the rotation of the core 220. When the chamber rotates to the third discharging hole 212, the door 222 corresponding to the chamber is opened, and the particles in the chamber are thrown out, and the distance of throwing out is different due to different densities of the particles. According to the throwing distance of the particles, the density of the rapeseed oil can be distinguished. By respectively arranging the granularity screening box 100 and the density screening box 200, the rapeseeds to be screened are screened from two aspects of granularity and density, so that the selected rapeseeds are ensured to meet the requirements.
In this embodiment, the aperture of the material leaking hole 310 is in the range of 50mm-100 mm. By controlling the aperture of the weep holes 310, the amount of particles entering each of the chambers can be controlled. When the amount of particles in each chamber is too large, the particles are stacked in the chamber, and when the particles are thrown out, the distance difference between the particles and the axis of the core 220 is large, so that the initial velocity difference in the horizontal direction is large, thereby affecting the distance to be thrown out, and also affecting the accuracy of screening. When there are too few particles in each of the chambers, the screening efficiency will be reduced.

Preferably, the motor is a speed-adjustable motor.
The faster the rotation speed of the core part 220 is, the farther the rapeseeds are thrown out, the longer the required collecting tank 400 is, and at the moment, the more the rapeseeds with different densities are dispersed, so that the rapeseeds with different densities can be screened more finely; the slower the speed of rotation of the core 220, the closer the rapeseeds are thrown, the shorter the collection gutter 400 required, and the more concentrated the rapeseeds of different density. The operator can vary the rotational speed of the core 220 by adjusting the rotational speed of the motor as desired.
