[0027] Reset springs 7 are fixedly installed at the bottom ends of both sides of the inner part of the limiting guide groove 3, and the top of the reset spring 7 is fixedly connected to the bottom end of the limiting end plate 4. A driving cam 8 is rotatably connected to the inner middle part of the limiting guide groove 3, and one side of the driving cam 8 is connected to a driving motor 9 through a driving shaft. The driving motor 9 is powered by an external power supply. The driving cam 8 is fixedly connected to the output shaft of the driving motor 9 through the driving shaft, and the driving motor 9 is fixedly installed on the outer edge of the processing box 1, so that the driving motor 9 can drive the driving cam 8 to rotate stably. Discharge grooves 10 are opened on both side edges of the processing box 1 corresponding to the limiting end plates 4, and the edge of the processing box 1 is fixedly connected with a guide groove plate 11 at the edge position of the discharge groove 10.

[0028] A distribution air box 12 is symmetrically arranged at the bottom edge positions on both sides of the interior of the processing box 1, and the edge ends of the distribution air box 12 are evenly connected with nozzles 13. The distribution air box 12 is embedded and installed in the side wall of the processing box 1, and a gas collecting box 14 is fixedly installed on the side edge of the distribution air box 12 away from the nozzle 13. Three groups of fans 15 are equidistantly installed on the edge of the gas collecting box 14. The distribution air box 12 and the gas collecting box 14 are interconnected, and the cross-sectional shape of the gas collecting box 14 is trapezoidal, which is convenient for centrally conveying the airflow generated by the fan 15 to the distribution air box 12, thereby improving the uniformity of the airflow distributed by the nozzle 13.

A handle 20 is installed in the middle of the front side of the collecting bottom box 16.

[0030] Working principle and use process of the utility model: In the actual application process of the rice processing stone removal device, the driving motor 9 is first started, and the driving motor 9 drives the driving cam 8 to rotate, and the driving cam 8 cooperates with the reset spring 7 to make the limit end plate 4 reciprocate along the limit guide groove 3. The limit end plate 4 drives the screen frame 5 and the screening screen 6 to reciprocate and rise and fall;

[0031] Next, the rice to be processed is added into the processing box 1 through the feed hopper 2. At this time, the mesh frame 5 and the screening net 6 in the processing box 1 both vibrate back and forth, thereby realizing that the screening net 6 shakes the rice with the reciprocating vibration, making it easier to separate the sand and stones from the rice, thereby improving the stone removal efficiency and stone removal effect of the rice in the actual processing process. In the process of the rice being screened through the screening net 6, the rice further falls through the screening net 6, and the sand and stones with large particle sizes in the rice will stay on the screening net 6. By setting the mesh frame 5 with a high middle and low sides, the sand and stones with large particle sizes can be quickly discharged along the two sides of the screening net 6 during the process of the screening net 6 screening the rice, and finally discharged from the processing box 1 through the discharge trough 10 and the guide trough plate 11, thereby improving the convenience of the sand and stone screening and removal process;

[0032] When the rice continues to fall after passing through the screening net 6, the fan 15 is started, and the airflow generated by the fan 15 is quickly and evenly blown into the processing box 1 through the distribution air box 12, the nozzle 13 and the air collecting box 14. When the rice passes through the screening net 6, the rice can enter the blowing area of ​​the nozzle 13 more evenly and dispersedly, so as to ensure the effect of airflow sorting. In this way, by arranging the processing airflow on both sides of the interior of the processing box 1, it is convenient to drive the rice and sand to be blown by airflow blowing. Due to the different qualities of rice and sand, the collection bottom box 16 and the middle collection chamber 17, the first side collection chamber 18 and the second side collection chamber 19 arranged therein are combined to facilitate the effective classification and collection of rice and sand according to their blowing distances.

[0033] Finally, when a certain amount of sand and rice is collected in the collecting bottom box 16, the collecting bottom box 16 can be conveniently pulled out from the bottom of the processing box 1 through the handle 20, so as to facilitate the subsequent effective classification and processing of rice and sand.

[0034] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
