[0031] Further as Figure 1-4As shown, it is worth explaining in detail that, in order to enable the blowing structure, the vibration structure and the intermittent feeding structure to be realized through the linkage of a single electric device, a linkage intermittent feeding structure 6 is provided, which includes a worm gear a61 fixedly connected to the outer side of an extension portion of one end of the rotating shaft a32 away from the upper discharge port, the outer side of the worm gear a61 is meshingly connected with a worm a62, the worm a62 is fixedly connected to the outer side of a transmission shaft 63, both ends of the transmission shaft 63 are rotatably connected to the left side wall of the screening box 1 through a bearing seat, the bottom end extension portion of the transmission shaft 63 is fixedly connected to the output shaft of the motor 68, the motor 68 is fixedly connected to the left side wall of the screening box 1, the top end extension portion of the transmission shaft 63 is fixedly connected to a turntable 613, the surface edge of the turntable 613 is fixedly connected to a transmission column 612, An L-shaped movable plate 69 is movably sleeved on the outer side of the movable column 612, and a transmission channel 611 matching the transmission column 612 is provided on the L-shaped movable plate 69. The L-shaped movable plate 69 is movably inserted into the feed square tube 2. A material passage 610 opened on the L-shaped movable plate 69 is provided on the right side of the feed square tube 2. A cam 67 is movably overlapped at the bottom end of the slider 14. The cam 67 is rotatably connected to the groove provided on the inner wall of the screening box 1 through the rotating shaft b66.

In addition, the rotating shaft b66 drives the cam 67 to rotate, so that the U-shaped lifting plate 11 can be reciprocated up and down. Combined with the action of the spring 15, the vibration screening of the screen plate 12 is realized, and the qualified rice is discharged outward through the upper discharge port, and the impurities such as stones that are screened out slide down to the outside through the discharge inclined plate 5;

[0034] In summary, the linkage of the blowing structure, the intermittent feeding structure and the vibration structure can be realized through a single motor 68, thereby greatly reducing the manufacturing cost of the equipment and achieving good use effect. In addition, by loosening the two hand screws 132, the screen plate 12 can be conveniently pulled out and replaced, which is easy to use.
