Problems solved by technology
The discharge port of this traditional grain screening machine is relatively large. When the rice enters the discharge bin from the discharge port at the bottom of the casing, the discharge of the rice will be too fast, causing the induced draft fan to be too late to suck out all the shriveled grains in the rice. Causes the screened rice to contain more shriveled grains

The invention discloses a grain screening machine. The grain screening machine comprises a chassis. The top of the chassis is provided with a housing. A screening drum is installed inside the housing obliquely. An inlet end of the screening drum is provided with a transmission gear ring and a power device that are in transmission connection. The screening drum is further provided with a plurality of wheel belts, wherein a riding wheel device is installed inside the housing below the wheel belts at an outlet end of the screening drum; the riding wheel device is in rolling connection with the wheel belts. A catch wheel device which is matched with the wheel belts is further installed between the riding wheel device and the power device. The bottom of the housing is provided with a plurality of impurity discharge hoppers. The right end of the housing is provided with a feed port and provided with an oblique feed pipe that extends inside the screening drum. The bottom at the left end of the housing is provided with a discharge port and is in butt joint with a discharge chamber. A draft fan is installed on the left side of the housing at the top of the chassis. The bottom of the draft fan is provided with a shriveled kernel discharge chamber. An exhaust pipe is installed between the draft fan and the top of the discharge chamber; and a set of screw feeding machine is installed at the discharge port. The grain screening machine is able to clear the shriveled kernels in the grains thoroughly. The screening rate is increased greatly; and the grain screening machine is mainly used for removing impurities in grains.
Description
technical field [0001] The invention relates to the field of agricultural machinery, in particular to a grain screening machine. Background technique [0002] Grain impurity removal is an essential step in the grain processing process. Its main purpose is to screen out the mud, stones, dust and shriveled grains in the grain to obtain clean grain for further processing into rice. [0003] The traditional grain screening machine has a frame, the top of the frame is equipped with a casing, and the casing is equipped with an inclined screen drum. The inlet end of the screen drum is equipped with a transmission ring gear, and a power device is installed in the casing below the transmission ring gear. The power device is connected in transmission with the transmission ring gear. There are also several wheel belts installed on the screen cylinder, among which the wheel belt at the discharge end of the screen cylinder is located in the casing and is equipped with a support roller d...
