Background Art

[0002] Peanut shelling machine is an important equipment in agricultural mechanized production. Its main task is to peel the shell of peanuts for subsequent processing or consumption. In the existing peanut shelling machine, peanuts are usually put into the machine manually. The peanuts first fall into the coarse screen. The peanut shells are peeled off by the rotation of the screen and the rubbing force between the fixed screen bars and the concave plates. Then, the peanut kernels and shells fall through the screen at the same time, and through the air duct, most of the peanut shells are blown out of the machine by wind. However, there are many disadvantages in its use. First, during the shelling process, the peanut shelling machine may cause a high crushing rate of the peanut kernels due to the relatively hard overall material of the machine and the rubbing back and forth on the surface of the peanuts. Secondly, the existing peanut shelling machine is easy to get stuck in the gap of the shelling net during the shelling process, resulting in blockage and affecting the shelling efficiency. Finally, in the process of separating peanut shells and peanuts, the existing equipment directly uses wind power to blow out the peanut shells and dust, which leads to the generation of a large amount of dust, which may pose a potential threat to the health of the staff. In addition, the peanuts are not filtered twice during the separation process, which may lead to poor separation effect and more peanut shells in the peanuts.

[0003] Announcement No. CN108685111B discloses a peanut shelling machine, which effectively solves the problems of low efficiency, large proportion of broken peanut kernels, low degree of automation, high cost, difficult operation, and inability to shell in large quantities in traditional peanut shelling; the technical solution is as follows: it includes a box body, a first cylinder is installed in the box body, a second cylinder is mounted on the outside of the first cylinder, a first long strip is provided on the inner wall of the first cylinder, and a second long strip is provided in the first cylinder; a slide is fixed on the inner wall of the box body cavity, two sliders are arranged in the slide, a chuck that can rotate on the slider is arranged on the side of each slider close to the second cylinder, a cylindrical block is fixed on the outer wall of the second cylinder, and the two chucks are close to or away from each other to limit the intermittent rotation of the second cylinder; Announcement No. CN106690339A discloses a peanut shelling machine, including a collecting hopper, a primary shelling box, a primary rotating scraper, a secondary shelling Box, secondary rotating scraper, grid, collecting body, peanut shell outlet, blower, peanut kernel outlet, residual grain collecting port, primary vibrating screen, secondary vibrating screen, peanut microwave heating chamber, spring and collecting plate, the grid is arranged on the box wall at the lower end of the secondary shelling box; an inclined primary vibrating screen is arranged at the lower end of the grid, a secondary vibrating screen is arranged obliquely below the primary vibrating screen, springs are arranged on the primary vibrating screen and the secondary vibrating screen, a collecting plate is arranged below the secondary vibrating screen, a residual grain collecting port is arranged at the lower end of the collecting plate, a blower is arranged between the primary vibrating screen and the secondary vibrating screen, the peanut shelling machine is easy to get stuck in the gap of the shelling net during the process of shelling peanuts, resulting in blockage, affecting the shelling efficiency, which not only reduces the production efficiency, but also the overall material of the structure for crushing peanuts is hard, which is easy to damage the peanut kernels.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A Peanut Shelling and Screening Machine", which uses a shelling component to squeeze and crush the peanut shells, and a screening component to collect the peanut shells and peanuts separately. However, the peanut shelling and screening machine cannot distinguish the quality of peanut kernels. During the shelling process, there may be dirt, dust and other fine impurities on the surface of the peanut kernels, and wind screening cannot effectively clean these impurities. In humid or rainy seasons, peanuts and their shells may contain high moisture content. The wet peanut shells may not be easily blown by the wind due to the increased weight. In this case, wind screening may not be effective. Summary of the invention

The screening box (13) is a rectangular parallelepiped structure with an open top. Preferably, the width of the screening box (13) gradually increases from the bottom to the quarter, and the bottom of the screening box (13) is a flat structure. The screening box (13) has a discharge port (28) at the middle of the bottom end. One side of the separation box (31) is fixedly connected to the side of the screening box (13). Preferably, the separation box (31) is a rectangular parallelepiped structure with an open top. A notch is formed at the top to one quarter of the connecting portion of the screening box (13) and the separation box (31). The first support plate (35) is fixedly placed on the other side of the screening box (13), which side is opposite to the side connected to the separation box (31). The blower (33) is fixedly placed on the first support plate (35). One end of the air blowing pipe (32) is connected to the air outlet of the blower (33), and the other end of the air blowing pipe (32) is connected to the screening box (13). The blower (33) is connected to the inside of the screening box (13) through the air blowing pipe (32). The bottom end is higher than the bottom end of the side notch. The water inlet pipe (34) is placed on the first support plate (35), one end of the water inlet pipe (34) is fixedly connected to the side of the screening box (13), and the water inlet pipe (34) and the screening box (13) are in communication. The second support plate (36) is fixedly placed on the other side of the separation box (31). The air pump (37) is fixedly placed on the top surface of the second support plate (36). The slag collecting box (39) is placed on the top surface of the second support plate (36); the slag collecting box (39) is in a rectangular parallelepiped structure and has a hollow structure inside; holes are opened on the top and one side of the slag collecting box (39); and a protective net is placed on the hole on the side of the slag collecting box (39). One end of the connecting air duct (38) is connected to the air inlet of the air pump (37), and the other end of the connecting air duct (38) is snap-connected to the side of the slag collecting box (39), and the connecting air duct (38) communicates with the slag collecting box (39) through a hole on the side of the slag collecting box (39). The hose (40) is fixedly placed on the top surface of the slag collecting box (39), and the hose (40) is made of a pulsator hose (40). Preferably, the hose (40) is in a cylindrical structure, and the hose (40) extends obliquely upward from one end connected to the slag collecting box (39) to a halfway point, and is bent in an arc shape from the halfway point to the other end. The slag inlet (41) is fixedly disposed at the other end of the hose (40). Preferably, the slag inlet (41) is of cylindrical structure, the cross-sectional diameter of the hose (40) gradually increases from one end to the other end, and the slag inlet (41) is connected to the interior of the slag collecting box (39) through the hose (40). When in use, the water screen structure is installed on the peanut shelling and screening machine, and clean water or salt water of a certain concentration is injected into the screening box (13) through the water inlet pipe (34). The height of the water is higher than the bottom of the separation box (31) and the connected side notch. The peanut shell is destroyed by the shelling component, so that the peanut shell and the peanut kernel are separated. As the peanut shell and the peanut kernel fall off, they fall into the water together. Since the density of the peanut shell is lower than the density of water, and the density of the peanut kernel is higher than the density of water, this difference causes the peanut kernel to sink to the bottom of the water, while the peanut shell floats on the water surface. In addition, due to the change in density and the influence of microbial activity, the rotten peanuts are likely to float on the water surface. Subsequently, the blower (33 ) is started to generate wind force into the screening box (13) through the air blowing pipe (32). This wind force blows the peanut shells floating on the water surface and the peanuts that may have deteriorated toward the surface of the clean water in the separation box (31). The air pump (37) is started to form a low-pressure area inside the slag collecting box (39), thereby guiding the peanut shells above the separation box (31) and the floating impurities to be sucked into the slag collecting box (39) through the slag inlet (41) and the hose (40). After the screening process is completed, the water and the screened peanuts can be discharged by opening the clamp to disconnect the air duct and the slag collecting box (39). Then, the slag collecting box (39) can be removed, and the peanut shells and impurities therein can be easily poured out from the side holes. Example 2
