[0024] Two balls 34 are embedded in the outer side of the slider 32 through the ball groove, and the surface of the balls 34 abuts against the inner wall of the separation box 1 .
[0025] The slider 32 is composed of two sliding ends and a cross - plate end. At the center position of the cross - plate end of the slider 32, an electric telescopic rod 35 is connected, and the end seat of the electric telescopic rod 35 is fixedly connected to the vertical plate 36. The bottom end of the vertical plate 36 is fixedly connected to the top - right side of the mesh basket frame 33.
[0026] A dust - proof net 39 is connected to the top - right side of the mesh basket frame 33 by bolts, and the length of the dust - proof net 39 is adapted to the length of the first filter plate 37.
[0027] The guiding member 4 includes a vertical plate 41, which is connected to the inner wall at the center position of the separation box 1. The top end of the vertical plate 41 is rotatably connected to a guiding plate 42 through a groove, and the central rotating shaft of the guiding plate 42 passes through the separation box 1 and is connected to a driving motor 43.
[0028] The vertical plate 41 divides the interior of the separation box 1. The right - hand side inside the separation box 1 is set as a discharge chamber, and a rectangular discharge port is opened at the bottom end of the discharge chamber.
[0029] A screen plate 61 is installed on the right - hand side inner wall of the separation box 1 by bolts, and a storage drawer 62 is arranged below the screen plate 61. The bottom end of the storage drawer 62 is in contact with the inner wall of the separation box 1, and the screen plate 61 is designed to be inclined.
[0030] By the movement of the slider 32 driving the ball 34 to rub, the contact area between the slider 32 and the inner wall of the separation box 1 is reduced. At the same time, the ball 34 rotates frictionally as it follows the movement of the slider 32, and the ball 34 guides the slider 32 during rotation, ensuring the smooth movement of the slider 32. The slider 32 is supported and controlled by the electric telescopic rod 35. At the same time, the slider 32 can drive the mesh basket frame 33 to swing during movement, and then the mesh basket frame 33 removes impurities from the corn kernels during swinging, causing the impurities to fall after being screened by the first filter plate 37. The swinging efficiency of the mesh basket frame 33 is controlled by the telescopic frequency of the electric telescopic rod 35 to control the impurity - removal effect of the corn kernels. The electric telescopic rod 35 is protected by the dust - proof net 39 to prevent the situation of impurity dust rebounding when pouring the corn kernels. The dust - proof net 39 can block the impurity dust, further improving the cleanliness of the corn kernels inside the mesh basket frame 33. Using the driving motor 43 as a power source, the guiding plate 42 is controlled to conduct side - guiding for the corn kernels and impurity particles falling inside the mesh basket frame 33, thus facilitating the secondary separation and guiding of the corn kernels and providing a basis for the secondary impurity - removal of the corn kernels. The secondary - screened corn kernels are stored in the discharge chamber of the separation box 1, which is convenient for guiding the screened corn kernels through the rectangular discharge port, facilitating the collection by the staff after impurity - removal. Due to the inclined setting of the screen plate 61, the corn kernels roll on the surface of the screen plate 61, so that the screen plate 61 conducts secondary screening on the corn kernels, improving the impurity - removal effect of the corn kernels.
[0031] Working principle: According to the attached Figure 2 And the attachedFigure 3 As shown, lift the top cover 2 and open it, pour the corn kernels containing impurities inside the mesh basket frame 33. At the same time, start the drive motor 43, the output end of the drive motor 43 drives the guide plate 42 to rotate, and the guide plate 42 tilts to the left during rotation. At this time, start the electric telescopic rod 35, the output end of the electric telescopic rod 35 reciprocates to drive the slider 32 to move, the slider 32 drives the mesh basket frame 33 to reciprocate during movement, and the mesh basket frame 33 swings back and forth during movement, so as to screen the impurities in the corn kernels, so that the impurity particles in the corn kernels fall onto the surface of the guide plate 42 after passing through the first filter plate 37, and the impurity particles slide out from the ash outlet 7 after being guided by the guide plate 42, and thus are collected by the staff with a cloth bag. After a large amount of impurities are screened, start the drive motor 43 to make the output end rotate in the reverse direction. During the rotation of the output shaft of the drive motor 43, the guide plate 42 is driven to tilt to the right. At this time, start the drive motor 38, the output end of the drive motor 38 drives the first filter plate 37 to rotate and open. After the corn kernels fall onto the guide plate 42 during the swing of the mesh basket frame 33, they slide down to the surface of the screen plate 61 after being guided by the guide plate 42. The screen plate 61 performs secondary screening on the impurities in the corn kernels, and the screened impurities fall into the storage drawer 62. At the same time, the corn kernels slide on the surface of the screen plate 61 and fall from the rectangular discharge port of the separation box 1, which is convenient for the staff to collect. When it is necessary to clean the bottom end inside the separation box 1, the door panel 5 can be rotated and opened, which is convenient for cleaning.
