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, 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, which leads to 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 accurately control the amount of peanuts poured in, and more peanuts are piled up above the crushing roller, which may cause the peanut shells to be incompletely crushed during the shelling process. In order to ensure that the peanuts can be completely shelled, the operator needs to manually control the amount of peanuts added each time and continue to add peanuts slowly during the operation of the machine, which not only increases the labor intensity, but also reduces the overall work efficiency.

The rotating support block (34) is fixedly placed on the side surface of the other end of the transmission shaft (40). The transmission cylinder (39) is annular in structure, a support bearing is disposed between the inner ring surface of the transmission cylinder (39) and the side surface of the transmission shaft (40), and the connection block (33) is disposed between the transmission cylinder (39) and a cylinder with a larger diameter at the other end of the transmission shaft (40). A connecting column (37) is fixedly disposed on the side of the rotating support block (34), and the connecting column (37) is slidably connected to a movable groove (38). Another connecting column (37) is disposed on one side of the transmission cylinder (39), and the connecting column (37) is slidably connected to another movable groove (38), and the central axes of the two connecting columns (37) and the transmission shaft (40) are all on the same plane.

The design of the support (28) being located close to the middle of the height of the processing cylinder (5) can divide the processing cylinder (5) into two parts, with the upper part storing peanuts and the lower part crushing peanut shells. This layout reduces the floor space occupied and allows the peanuts to fall naturally under the action of gravity without the need for additional conveying equipment, thereby improving work efficiency. The inner side surfaces of the two side plates of the bracket (28) are provided with slide rails (36), which facilitates the smooth movement of the sliding plate (32) and improves the flexibility and efficiency of operation; The first curved plate (31) and the second curved plate (41) have the same diameter and are both smaller than the diameter of the inner side surface of the processing cylinder (5), thereby ensuring that the first curved plate (31) and the second curved plate (41) can be smoothly turned over inside the processing cylinder (5); The design that the arc surfaces of the first arc plate (31) and the second arc plate (41) are on the same circle ensures that the first arc plate (31) and the second arc plate (41) can form a continuous curved surface when closed, thereby dividing the interior of the processing cylinder (5) and effectively blocking the peanuts above; The purpose of achieving the purpose of being able to drive the first arc plate (31) and the second arc plate (41) to turn over synchronously by the electric push rod (35) is to realize automatic quantitative feeding and continuous shelling of peanuts.

Preferably, the peanut kernel collection box (8) is a rectangular parallelepiped structure with an open top.

The three sides of the second screen (23) are fixedly connected to the inner side of the screening bin in the processing box (3); the other side of the second screen (23) is fixedly connected to the partition (19); the second screen (23) is placed at an angle; the distance between the second screen (23) and the bottom surface of the processing box (3) gradually decreases from one end intersecting with the partition (19) to the other end.

Preferably, the diameter of the second sieve hole (24) is smaller than the diameter of the first sieve hole (21), and the second sieve (23) is placed below the first sieve (22) at a certain distance. The partition plate (19) is provided with a transfer port (20), and the transfer port (20) is disposed between the first screen (22) and the second screen (23). 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. The outer side of the peanut kernel collection box (8) is fixed with a handle (1), and the outer side of the peanut shell collection box (2) is fixed with a handle (1). 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 peanut shells and the peanut kernels fall into the peanut shell collection box (2) through the gap between the ends, while the peanut kernels and the peanut shells that have not been completely screened pass through the holes of the first screen (22) and reach the second screen (23). 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 design that the peanut shell collection box (2) is slidably connected to the collection bin through the notch, and the peanut kernel collection box (8) is slidably connected to the screening bin through the notch facilitates 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.
