[0002] Millet is a cereal crop, which is called "millet" after being shelled. It is rich in nutrients such as carbohydrates, proteins, vitamins and minerals. After millet is shelled, in order to improve its quality and purity, it is necessary to remove impurities such as bran and dust remaining in the millet. Winnowing is a method or technology that uses wind power to separate millet from bran, dust and other debris. However, since the bran is the outer shell of millet and its shape is relatively irregular, millet may get stuck in the bran. In this case, the bran cannot be directly removed by wind due to the weight of the millet, which affects the quality and purity of the millet. Summary of the invention

DETAILED DESCRIPTION

[0015] See also Figure 1-Figure 3The utility model provides the following technical solution: including an outer shell 1 and a fan 14, characterized in that: the inner walls on both sides of the outer shell 1 are respectively provided with a fixing block 12 and a fixing block 2 13, the bottoms of the fixing blocks 12 and 13 are both provided with an elastic pad 121, the inner walls on both sides of the outer shell 1 are respectively provided with a receiving plate 1 2 and a receiving plate 2 3, the tops of the receiving plates 1 2 and 2 3 are both provided with an elastic pad 21, and the tops of the receiving plates 1 2 and 2 3 are both inclined surfaces, and the elastic pad 2 A plurality of springs 212 are arranged inside 21, a fixed block 12 and a receiving plate 2 are respectively located on the inner walls on both sides of the outer shell 1, the receiving plate 2 is lower in height than the fixed block 12, a fixed block 13 is located at the bottom of the receiving plate 2, a receiving plate 23 is located at the bottom of the fixed block 12, the receiving plate 23 is lower in height than the fixed block 2 13, a debris discharge port 15 is opened on one side of the outer shell 1, a fan 14 is located on the other side of the outer shell 1, and a millet discharge port 16 is opened at the bottom of the outer shell 1.

[0016] In this embodiment, it includes an outer shell 1 and a fan 14. When the millet passes in front of the fan 14, the fan 14 can remove impurities such as bran mixed in the millet, thereby achieving the purpose of improving the quality and purity of the millet. The inner walls on both sides of the outer shell 1 are respectively provided with a fixed block 12 and a fixed block 2 13. The fixed block 12 and the fixed block 2 13 are staggered with each other. The height of the fixed block 12 is higher than the fixed block 2 13. The top and bottom of the fixed block 12 and the fixed block 2 13 are both inclined surfaces. When the millet falls to the top of the fixed block 12 or the fixed block 2 13, it can fall downward along the inclined surface. The bottoms of the fixed block 12 and the fixed block 2 13 are both provided with an elastic pad 121. The elastic pad 121 is made of a high elastic material. The inner walls on both sides of the outer shell 1 are respectively provided with a fixed block 12 and a fixed block 2 13. A receiving plate 1 2 and a receiving plate 2 3 are separately provided. The receiving plate 1 2 and the fixing block 2 13 are located on the same side, and the receiving plate 2 3 and the fixing block 1 12 are located on the same side. The tops of the receiving plate 1 2 and the receiving plate 2 3 are both provided with an elastic pad 21. When the millet falls downward to the top of the elastic pad 21, the millet can bounce upward by the elastic force of the elastic pad 21, so that the bran can be separated from the millet by the vibration and upward bouncing action when the millet falls multiple times, and the dispersion rate of the millet can also be improved at the same time. The tops of the receiving plate 1 2 and the receiving plate 2 3 are both inclined surfaces. When the millet falls onto the elastic pad 21 on the top of the receiving plate 1 2 or the receiving plate 2 3, it will tilt and bounce upward. When the bouncing of the millet stops, the millet will move along the receiving plate 1 2 and the receiving plate 2 3 moves downward at an inclination angle, and a plurality of springs 212 are arranged inside the elastic pad 21. The plurality of springs 212 are conducive to improving the elastic force of the elastic pad 21, so that the Xiaomi's bounce amplitude is larger. The fixed block 12 and the receiving plate 2 are respectively located on the inner walls of both sides of the outer shell 1, and the height of the receiving plate 2 is lower than the fixed block 12. The fixed block 12 is located obliquely above the receiving plate 2. When Xiaomi falls onto the elastic pad 21 at the top of the receiving plate 2, it will tilt upward and bounce up to contact the elastic pad 121 at the bottom of the fixed block 12. The elastic force of the elastic pad 121 will make Xiaomi rebound to the elastic pad 21 at the top of the receiving plate 2. Therefore, Xiaomi will experience multiple bounces when passing between the receiving plate 2 and the fixed block 12. The second fixing block 13 is located at the bottom of the receiving plate 2, and the receiving plate 23 is located at the bottom of the fixing block 12. The millet passing between the receiving plate 2 and the fixing block 12 will fall to the top of the receiving plate 23. The height of the receiving plate 23 is lower than the fixing block 13. The same as the receiving plate 2 and the fixing block 12, when the millet passes between the receiving plate 23 and the fixing block 13, it will also experience multiple bounces and rebounds. A debris discharge port 15 is provided on one side of the outer shell 1, and the fan 14 is located on the other side of the outer shell 1. When the millet passes between the receiving plate 23 and the fixing block 13, it will fall downward.Thus, the millet can pass between the fan 14 and the debris discharge port 15, and the fan 14 can blow the impurities such as chaff in the millet toward the debris discharge port 15, so that the impurities such as chaff are discharged outward from the position of the debris discharge port 15. A millet discharge port 16 is provided at the bottom of the outer shell 1. When the millet passes through the fan 14, since the weight of the millet is greater than the impurities such as chaff, the millet will directly fall downward from the position of the millet discharge port 16, which is convenient for collecting the millet. , fixed block 12, receiving plate 23, fixed block 213, elastic pad 121 and elastic pad 21 make the millet bounce and rebound many times before being selected by wind, so that the millet and the bran are separated in the multiple contacts with elastic pad 21 and elastic pad 121, avoiding the situation that the millet and the bran are stuck together, resulting in the decrease of the wind selection efficiency, which is beneficial to improve the quality and purity of the millet. At the same time, through the multiple bounces and rebounds of the millet, the millet can be fully dispersed, further improving the efficiency of the wind selection.

[0017] A feed trough 11 is provided at the top of the outer shell 1, and the feed trough 11 corresponds to the position of the millet outlet 16. A receiving plate 2 is located at the bottom of the feed trough 11, and a plurality of support rods 17 are provided at the bottom of the outer shell 1. When millet enters the interior of the outer shell 1 from the position of the feed trough 11, the millet will fall to the top of the receiving plate 2 below.

[0018] The bottom of the fixed block 12 is an inclined surface, and the fixed block 12 has the same size as the fixed block 2 13; the fixed block 12 has the same function as the fixed block 2 13, which is used to intercept the bounced millet and make it rebound through the elastic pad 121.

[0019] The sizes of the receiving plate 1 2 and the receiving plate 2 3 are the same, and the bottom of the fixed block 12 is parallel to the top of the receiving plate 2, and the elastic pad 121 and the elastic pad 21 which are in close position are parallel; the position of the fixed block 12 and the receiving plate 2 are close, and Xiaomi will pass between the fixed block 12 and the receiving plate 2, and the position of the fixed block 2 13 and the receiving plate 2 3 are also close, and Xiaomi will also pass between the fixed block 2 13 and the receiving plate 2 3.

[0020] An empty slot 211 is provided inside the second elastic pad 21 , and a plurality of springs 212 are located inside the empty slot 211 ; the plurality of springs 212 are located inside the second elastic pad 21 so as not to be exposed to the outside.

[0021] The working principle and use process of the utility model are as follows: when in use, the millet to be processed needs to be put into the interior of the outer shell 1 from the position of the feed trough 11, and the millet will fall onto the elastic pad 21 at the top of the receiving plate 2, and the elastic force of the elastic pad 21 will make the millet tilt and bounce upward, and the fixed block 12 is located at the upper side of the receiving plate 2. When the millet falls onto the elastic pad 21 at the top of the receiving plate 2, it will tilt and bounce upward and contact the elastic pad 121 at the bottom of the fixed block 12, and the elastic force of the elastic pad 121 will make the millet rebound to the elastic pad 21 at the top of the receiving plate 2. Therefore, when the millet passes between the receiving plate 2 and the fixed block 12, it will experience multiple bounces and rebounds, and then the millet will continue to be guided by the receiving plate 2. The millet continues to fall downward to the elastic pad 21 on the top of the receiving plate 23. When the millet passes between the receiving plate 23 and the fixed block 213, it will also bounce and rebound many times, which is conducive to separating the millet and the bran in multiple contacts with the elastic pad 21 and the elastic pad 121, and can also disperse the millet. After passing between the receiving plate 23 and the fixed block 213, the millet will fall downward, so that the millet can pass between the fan 14 and the debris discharge port 15. The fan 14 can blow the bran and other impurities in the millet toward the debris discharge port 15, so that the bran and other impurities are discharged outward from the position of the debris discharge port 15. Since the weight of the millet is greater than the bran and other impurities, the millet will directly fall downward from the position of the millet discharge port 16.
