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 pass through the air duct, using wind to blow most of the peanut shells out of the machine. 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 to blow out the peanut shells and dust, resulting in the generation of a large amount of dust near the shelling machine, posing a potential threat to the health of the staff. Finally, the peanuts are not filtered twice during the separation process, the separation effect is poor, and there are more peanut shells in the 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 or elastically 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 or elastically 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; The second sieve (23) has a second sieve hole (24), and a plurality of the second sieve holes (24) are provided.

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

[0014] 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

[0015] 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.

[0016] It should be noted that, unless otherwise clearly specified and limited, the terms "placed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection method such as a folding connection, a rivet connection, a pin connection, a bonding connection and a welding connection, or a detachable connection method such as a threaded connection, a snap connection and a hinge connection, or an integral connection, or an electrical connection, or a direct connection, or an indirect connection through an intermediate medium, or the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
