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. The existing peanut shelling machine usually puts peanuts 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, 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. Secondly, in the process of separating peanut shells and peanuts, the existing equipment directly uses wind power to blow out the peanut shells and dust, resulting in the generation of a large amount of dust, which may pose a potential threat to the health of the staff. Finally, 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 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 above 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 bottom surface of the screening bin is an open structure. The processing box (3) has a square hole on its top surface and is placed in the middle of the collection bin. The dust cover (29) is inserted into the hole on the top of the collecting bin. A handle (1) is fixedly disposed on the top surface of the dust cover (29). The support column (28) is fixedly placed on the bottom surface of the processing box (3), and there are four support columns (28), which are respectively placed near the four corners of the bottom surface. The support plate (32) is fixedly placed on the side and on the side of the screening bin. The water pump (31) is fixedly placed on the support plate (32). One end of the water pipe (30) is connected to the water outlet of the water pump (31), and the other end passes through a side surface and is placed in the screening bin. A drainage fan (33) is disposed on the side of the screening bin, and the side is opposite to the partition (19). Preferably, the lowest point of the drainage fan (33) is higher than the top of the partition (19). The filter water box (34) is placed in the collection bin. Preferably, the water filter box (34) is a rectangular parallelepiped structure, the water filter box (34) is an open top structure, and the length and width are smaller than the size of the collection bin, and the height of the water filter box (34) is less than or equal to the height of the partition (19). The water filter box (34) has a water filter hole (35) on the side thereof. Preferably, the water filter holes (35) are provided in plurality, and the plurality of water filter holes (35) are evenly distributed on the side of the water filter box (34). The screening box (39) is a square cylindrical structure, the outer side of the water pipe (30) is fixedly connected to the inner side of the screening bin, and is also fixedly connected to one side of the partition (19). Preferably, the top of the screening box (39) and the top of the partition (19) are on the same plane, the width of the screening box (39) remains constant from the top to the halfway point, and gradually decreases from the halfway point to the bottom, and the bottom width is not less than half of the top width. The ramp (40) is fixedly placed on the bottom surface of the screening box (39). Preferably, the inclined opening (40) is a rectangular parallelepiped structure, the height of which gradually decreases from one end close to the partition (19) to the other end, and the inclined opening (40) is a top open structure. The ramp opening (40) is provided with a square hole near the side of the partition (19). The sealing plate (37) is plug-in-connected and placed on the side hole of the inclined opening (40), and a rubber strip is clamped on the side. A first electric push rod (38) is disposed between the partition (19) and the sealing plate (37), one end of the first electric push rod (38) being fixedly connected to the partition (19), and the other end of the first electric push rod (38) being fixedly connected to the sealing plate (37). The collecting bin has a circular hole on the side near the bottom, and a filter screen is fixed on the hole. The screening box (39) has a circular hole on the side near the bottom, and a filter screen is fixed on the hole. The screening bin has a circular hole on the side near the bottom. Two water outlet valves (36) are provided, one of which is fixedly connected to a circular hole on the side of the collecting bin, and the other of which has one end fixedly connected to a circular hole on the side of the screening box (39) and the other end passing through the side of the screening bin and fixedly connected to a hole on the side of the screening bin. When in use, after starting the water pump (31), clean water is injected into the screening bin through the water pipe (30). When the water level is flush with the top of the partition (19), the speed of injecting water is reduced, and the shelling assembly is used to destroy the peanut shells, so that the peanut shells and peanut kernels are separated. As the peanut shells and peanut kernels fall off, they fall into the water together. In the process of falling into the water, the drainage fan (33) generates wind force on part of the peanut shells, causing them to fall into the water filter box (34). After the peanut kernels and the remaining peanut shells enter the water, the density of the peanut shells is lower than the density of water, while the density of the peanut kernels is higher than the density of water. This difference causes the peanut kernels to sink to the bottom of the water, while the peanut shells float on the surface of the water. In addition, due to the change in density and the influence of microbial activity, the rotten peanuts are There is a high possibility that the peanuts will float on the water surface. Subsequently, the drainage fan (33) generates wind force on the water surface, blowing the peanut shells floating on the water surface and the peanuts that may have deteriorated into the water filter box (34). After the screening process is completed, the water outlet valve (36) is opened, and water can flow out of the processing box (3) through the water filter hole (35) and the water outlet valve (36), while the peanut shells and impurities are left in the water filter box (34). The clean water in the screening box (39) flows out through the water outlet valve (36), driving the first electric push rod (38) to drive the sealing plate (37) to move toward the partition (19), so that the peanut kernels flow out through the side notch of the slope opening (40). Finally, the dust cover (29) is opened, and the water filter box (34) is raised to clean the peanut shells inside. Example 2

[0014] The difference between this embodiment and embodiment 1 is that: a placement plate (42) is fixedly arranged on the outer surface of the inner screening bin, and the side surface is opposite to the partition (19), a circular hole is opened on the side surface of the placement plate (42), and a circular hole is opened on the side surface connected to the placement plate (42), one end of the second electric push rod (43) is placed in the inner screening bin, and the other end passes through the placement plate (42), and the side surface of the second electric push rod (43) is fixedly connected to the side surface of the hole of the placement plate (42), a scraper (41) is fixedly arranged on the side surface of one end of the second electric push rod (43), the bottom end of the scraper (41) is slightly higher than the plane where the top end of the partition (19) is located, and the bottom surface of the scraper (41) is fixedly arranged on a silica gel strip. When in use, the electric push rod is driven to drive the scraper (41) to slide toward the collecting bin, so that the peanut shells left in the screening box (39) can be pushed into the water filter box (34), thereby ensuring that the peanut kernels are not mixed with peanut shells and impurities; Example 3

The inclined opening (40) is a rectangular parallelepiped structure, and its height gradually decreases from one end close to the partition (19) to the other end. The inclined opening (40) is a top opening structure. The side of the inclined opening (40) close to the partition (19) is provided with a square hole, which helps the material to move naturally to the lower end under the action of gravity, thereby promoting the discharge of the peanut kernels. The sealing plate (37) is pluggably connected and placed on the side hole of the slope opening (40), and a rubber strip is clamped on the side, thereby increasing the sealing effect of the entire device and preventing clear water from flowing out during the peanut screening process; The purpose of being able to distinguish peanuts and peanut shells through water, preliminarily cleaning the peanut kernels and improving the screening effect is achieved.

A notch is provided on the side of the collecting bin in the processing box (3), and the peanut shell collecting box (2) is slidably connected through the notch and placed in the collecting bin. Preferably, the peanut shell collection box (2) is a rectangular parallelepiped structure with an open top.

A fan (7) is disposed on the side of the screening bin in the processing box (3), and the side is opposite to the partition (19). Preferably, the fans (7) are provided in two groups, one group of the fans (7) is placed between the first screen (22) and the top surface of the processing box (3), and the other group of the fans (7) is placed between the second screen (23) and the first screen (22). When in use, after peanuts are poured into the feed port (4), the motor (6) is started to drive the transmission gear (17) to rotate. The meshing relationship between the crushing gear (16) and the transmission gear (17) drives the crushing gear (16) to rotate, and the crushing roller (15) can be rotated around the central axis of the connecting shaft (12) through the connecting shaft (12). During the rotation process, the distance between the crushing roller (15) and the processing chamber (14) changes, so that an extrusion force can be applied to the peanuts to achieve crushing. The peanuts after being squeezed fall into the screening bin of the processing box (3). At this time, the wind force generated by the fan (7) acts on the peanuts, so that the peanut shells and dust pass through the processing box (3) and the partition (19) on the top.

The fan (7) plays its role again, and uses wind force to blow the peanut shells and dust into the peanut shell collection box (2) through the conveying port (20), thereby achieving secondary screening. When the peanut shells and the peanut kernels fall on the first screen (22) and the second screen (23), a certain rebound force is generated, so that the peanut shells and the peanut kernels are lifted up again, making it easier for the fan (7) to screen them. Finally, the peanut kernels pass through the holes of the second screen (23) and fall into the peanut kernel collection box (8), thereby achieving shelling and screening of the peanuts. Example 2

[0017] The difference between this embodiment and embodiment 1 is that a connecting plate (25) is fixedly arranged between the feed port (4) and the processing cylinder (5); the connecting plate (25) is a rectangular parallelepiped structure; one side of the connecting plate (25) is an open structure; a hole is formed from the top to the bottom of the connecting plate (25); the diameter of the hole is the same as the diameter of the inner side of the processing cylinder (5); the hole and the processing cylinder (5) are coaxially arranged; the baffle (26) is slidably connected to the inner side of the connecting plate (25); when in use, the size of the hole on the connecting plate (25) can be controlled by pulling the baffle (26), thereby controlling the feeding speed of the peanuts; Example 3

[0018] The difference between this embodiment and embodiment 1 is that a protective ring (27) is fixedly disposed on the inner side of the processing chamber (14), and the protective ring (27) is made of rubber. When in use, the protective ring (27) can buffer the peanut kernels, effectively absorb and disperse the force generated during the extrusion process, and avoid damage to the peanut kernels during the extrusion process of the peanut shells. The feed inlet (4) has a cross-sectional diameter that remains constant from the top to the halfway point and gradually decreases from the halfway point to the bottom, so that the peanuts can smoothly enter the processing cylinder (5), reducing the risk of blockage and preventing the peanuts from scattering around the feed inlet (4), thereby reducing the cleaning work; There are four support rods (10), which are arranged equidistantly along the circumference of the support ring (11), and there are gaps between the support rods (10), which can fix the position of the support ring (11) and the components connected thereto, and can allow the peanuts to pass quickly, thereby avoiding clogging of the processing cylinder (5); The gear dust cover (9) is designed to be hollow cylindrical, which can effectively seal the crushing gear (16) and the transmission gear (17), prevent dust and debris from entering, and extend the service life of the gears; The cross-sectional diameter of the crushing roller (15) gradually increases from the top to four-fifths, and remains unchanged from the four-fifths to the bottom, and the diameter increasing speed from the top to one-fifth is greater than the diameter increasing speed from one-fifth to four-fifths. The top of the crushing roller (15) is designed in an arc-shaped structure. The smaller diameter of the upper part allows the material to be concentrated and guided downward, and can also perform preliminary crushing on peanut shells with a relatively large volume. The larger diameter design at the bottom ensures that peanut shells with a relatively small volume can also be crushed, thereby ensuring that the peanut shells can be fully crushed and reducing omissions. The diameter of the second sieve hole (24) is smaller than the diameter of the first sieve hole (21); the second sieve (23) is placed below the first sieve (22) and is designed with a certain distance, so that the peanuts can be screened twice, thereby improving the screening efficiency; The peanut shell collection box (2) is slidably connected to the collection bin via the notch, and the peanut kernel collection box (8) is slidably connected to the screening bin via the notch, thereby facilitating the collection of peanut shells and peanut kernels. The fans (7) are designed to be provided in two groups with different heights, thereby improving the efficiency of wind screening, so that the peanut shells and dust can be separated more thoroughly; The purpose of squeezing and crushing the peanut shells by the shelling component and collecting the peanut shells and peanuts separately by the screening component is achieved.
