（2）机架用来固定驱动轴和被动轴，使选料带能绕驱动轴和被动轴旋转，机架

(2) The frame is used to fix the drive shaft and the passive shaft, so that the material selection belt can rotate around the drive shaft and the passive shaft. The frame itself has a certain inclination. When the material reaches the material selection belt from the feeding hopper, the accompanying direction Move after moving. Since the material selection belt has a corresponding shaping angle with the frame, the entire belt surface forms a curved surface. When the material moves along this curved belt surface, the whole grain and good roundness material will also be downward and leftward. The movement of the belt surface (because the belt surface is low left, right high, front low and rear high), finally flows into the whole grain discharge hopper on the left side of the machine, and is collected. The broken half-grain material is easy to contact the belt surface without rolling, and The material selection belt continues to move backwards until it is collected in the broken half-grain discharge hopper at the rear of the machine, and the whole and half-grain materials are separated.

(2) the frame is used to secure the drive shaft and passive shaft, so that the picking belt can be rotated around the drive shaft and passive shaft, the rack itself has a certain inclination, when the material from the feeding bucket to the picking belt, with the band moving backward. Since the picking strip with the rack also has the corresponding shaping angle, the entire strip surface forms a surface, when the material moves with this ribbon face, wherein the whole grain of well-rounded material also produces downward and left movement (due to the band left low, right high, front low high after), and finally into the left side of the machine in the whole batch of the hopper collected, and the broken half of the material is easy to form a surface contact with the strip surface, do not roll, and with the picking belt continues to move backward, until the back of the machine is collected in the crushed half-grain hopper, The whole grain is thus separated from the crushed half grain.

(2) The rack is used to fix the drive shaft and the passive shaft, so that the material selection belt can rotate around the drive shaft and the passive shaft. The frame itself has a certain inclination angle. When the material reaches the material selection belt from the feeding bucket, it moves with the belt backward. As the material selection belt has the corresponding setting angle along with the rack, the whole belt surface forms a curved surface. When the material moves along with the curved belt surface, the material with good roundness will move downward and left (because the belt surface is low in the left, high in the right, low in the front and high in the back), and finally flows into the whole grain discharge hopper on the left side of the machine for collection, and the materials with half grains are easy to form with the belt surface Face to face contact and do not roll, but continue to move backward with the selection belt until they are collected in the discharge hopper at the rear of the machine, so that the whole grain and the broken half grain material are separated.<br>
