Through the pipe connecting the storage barrel 101 and the screening barrel 105, the naked oats in the storage barrel 101 flow into the screening barrel 105. The motor on each of the two fan-shaped brackets 103 drives the two swing rods 104 to rotate, thereby driving the side round rods 108 to move along the slide groove on the fan-shaped bracket 103, thereby driving the screening barrel 105 and the rotating sleeve 106 to rotate, and further driving the screening barrel 105 and the rotating sleeve 106 to change from a vertical state to a horizontal state; After the screening barrel 105 is changed from a vertical state to a horizontal state, the cylindrical gear 114 is driven to rotate by the motor on the square plate 112, thereby driving the large gear 115 to rotate, and further driving the stirring rod 116 to move along the slide groove on the square plate 112, so that the multiple stirring rods 116 are stretched out and the distance to the inner wall of the screening barrel 105 is shortened, so that the naked oats are squeezed to a place close to the inner wall, and the naked oats are screened and peeled; the connecting bracket 113 is driven to rotate by the small motor 109, thereby driving the square plate 112, the cylindrical gear 114, the large gear 115 and the stirring rod 116 to rotate, so that the multiple stirring rods 116 are continuously rotated to screen and peel the naked oats inside the screening barrel 105; After the oatmeal is initially screened and peeled, it is straightened by the screening barrel 105, and then the motor on the screening barrel 105 drives the bottom baffle 107 to rotate, thereby opening the bottom baffle 107, so that the oatmeal falls from the inside of the screening barrel 105. In the process of the oatmeal falling into the small conical rack 206, the hair dryer 205 is used to blow air on the oatmeal to blow away light impurities, and the oatmeal falls into the cylindrical barrel 207 and the cylindrical long tube 208.

After a certain period of time, the water is drained from the storage barrel 211 to leave the oatmeal. Then, the electromagnetic valve under the storage barrel 211 is opened to let the oatmeal flow out and fall onto the conical block of the large conical frame 212, and then fall onto the circular plate of the large conical frame 212 along the inclined surface of the conical block, and then the two electric cylinders 218 are synchronously extended and retracted to drive the ring bracket 213, the long rod 214, and the first The connecting rocker 215, the circular plate 216, and the second connecting rocker 217 descend, causing the circular plate 216 to squeeze the oatmeal. Subsequently, the motor on the annular bracket 213 drives the long rod 214 to move, thereby driving the first connecting rocker 215 and the second connecting rocker 217 to swing, thereby driving the circular plate 216 to rotate, further causing the circular plate 216 to grind off the skin of the oatmeal. Subsequently, the two electric cylinders 218 drive the two trough-shaped support plates 219 to rise. Subsequently, the oatmeal on the circular plate of the large conical rack 212 is manually cleaned into the collection box 220 for drying and subsequent screening. If the first screening and peeling effect is good and the oats can be directly ground, the two screw moving mechanisms 201 drive the bottom support plate 202 and the rectangular support plate 204 to move synchronously. When the oats are screened and peeled for the second time, the storage barrel 211 is moved to the bottom of the cylindrical tube 208. When the oats are directly ground, the two screw moving mechanisms 201 drive the bottom support plate 202 and the rectangular support plate 204 to move synchronously, and the grinder 203 is moved to the bottom of the cylindrical tube 208.
