[0002] Soybean, also known as soybean, is an annual herb and one of the most important legume varieties in the world. It is widely used in the brewing industry as a raw material for the preparation of various condiments such as soy sauce and sauces. Yellow soybean is the most widely planted variety of soybean. Yellow soybean is most commonly used to make various soy products, brew soy sauce and extract protein. Bean dregs or ground into coarse powder are also commonly used as poultry and livestock feed. When used as various soy products, squeezing soybean oil, brewing soy sauce and extracting protein, high-quality soybeans with full particles and no broken particles need to be selected. Therefore, the soybeans must be screened before cleaning and crushing.

[0032] In the embodiment of the present invention, specifically, the mesh sizes of the multiple screening grids 14 are different and can be replaced according to the size of the screened soybeans;

[0033] In the embodiment of the present invention, further, a conical diverter frame 7 is slidably installed inside the screening body 1, an elastic connecting tube 701 is connected between the top surface of the conical diverter frame 7 and the feed hopper 4, a guide plate 12 is fixed inside the conical diverter frame 7, and a conical unloading frame 13 is provided below the guide plate 12, and a plurality of unloading ports 1301 are provided inside the conical unloading frame 13, and a driving component is provided outside the conical diverter frame 7 for driving the conical diverter frame 7 to reciprocate inside the screening body 1, so that the soybeans fall evenly to the screening grid frame 14 below, with reference to Figure 4-Figure 6 The guide plate 12 is installed obliquely. When the soybeans enter the conical diverter frame 7 through the elastic connecting tube 701, the soybeans can roll along the guide plate 12 until they pass through the guide plate 12 and are discharged through multiple discharge ports 1301. At this time, the soybeans can evenly fall through the bottom of the conical diverter frame 7 until they fall on the top of the screening grid frame 14 for screening. As the conical diverter frame 7 reciprocates inside the screening body 1, the soybeans poured into the feed hopper 4 can be evenly laid on the top of the screening grid frame 14, which effectively improves the screening efficiency and ensures the subsequent air selection effect.

[0034] In the embodiment of the present invention, further, an arc-shaped collecting rack 11 is fixed to the side of the conical diverter rack 7, a negative pressure pipe 1102 is connected to the outside of the arc-shaped collecting rack 11, and the end of the negative pressure pipe 1102 passes through the screening body 1 and is connected to the negative pressure pump body 3, the negative pressure pump body 3 is fixed to the outside of the screening body 1, and a blowing rack 8 is fixed to the side of the conical diverter rack 7 away from the arc-shaped collecting rack 11, and a blower is connected to the end of the blowing rack 8, which is used to blow impurities, debris and unqualified soybeans to the arc-shaped collecting rack 11 when the soybeans fall through the conical diverter rack 7, and then extract them through the operation of the negative pressure pump body 3, refer to Figure 3-Figure 6 The blowing rack 8 is used for air separation.
