The grading bin is provided with fixing holes corresponding to the positions of the threaded holes. The ends of the non-porous plate and the mesh plate are integrally connected with a discharge port;

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 4 As shown, a raw grain grading device of the present invention includes a base frame 1, through holes 2 are provided at the four corners of the base frame 1, a grading bin 3 is placed on the upper side of the base frame 1, a guide rod 4 is fixedly connected to the bottom of the grading bin 3, the guide rod 4 is slidably installed in the through hole 2, a spring 5 is installed between the grading bin 3 and the base frame 1, the spring 5 is located outside the guide rod 4, a vibration motor 6 is fixedly installed on the base frame 1, and the output end of the vibration motor 6 contacts the center position of the outer bottom of the grading bin 3;

[0026] The grading bin 3 is open only on the upper side and one end. Multiple groups of slideways 7 are symmetrically installed on the left and right sides of the grading bin 3. A non-porous plate 8 is placed in the slideway 7 on the lowermost side, and mesh plates 9 are placed in the other slideways 7. The aperture size of each mesh plate 9 is different. The larger the aperture size of the mesh plate 9, the closer it is installed. Threaded holes 10 are provided on the left and right sides of the non-porous plate 8 and the mesh plate 9. The grading bin 3 is provided with fixing holes 11 corresponding to the positions of the threaded holes 10. The ends of the non-porous plate 8 and the mesh plate 9 are integrally connected with a discharge port 12;

[0027] A hopper 13 is installed on the top of the grading bin 3, and the output end of the hopper 13 corresponds to the top surface of the mesh plate 9 located at the uppermost side.

[0028] In this embodiment, when a raw grain grading device is used, the raw materials enter the grading bin 3 from the hopper 13. During the grading process, the vibration motor 6 runs, and cooperates with the spring 5 to make the entire grading bin 3 vibrate on the upper side of the base frame 1;

[0029] Under the shaking effect, the raw grains move from the hopper 13 to the mesh plate 9 and are flattened. Under the squeezing of the flattening, the raw grains slowly move toward the discharge port 12. During this process, the raw grains passing through the holes of the mesh plate 9 fall into the mesh plate 9 of the next layer until they fall onto the non-porous plate 8 at the lowest position. In this way, the purpose of obtaining raw grains of different particle sizes from the discharge ports 12 on the mesh plates 9 at different heights is achieved.

[0030] By loosening the fasteners at the position of the threaded hole 10, the mesh plate 9 can be pulled out of the slide 7, so that the mesh plate 9 can be replaced and maintained. By replacing the mesh plate 9 with different mesh apertures, the raw grain with the required aperture can be graded.

[0031] Preferably, the discharge port 12 is provided with a discharge barrel 14, and the discharge barrel 14 and the fixing hole 11 are matched with locking screws. The end of the discharge barrel 14 is connected to a drainage bag 15. Such a design is conducive to quickly draining the graded raw grain to the collection position for collection. In fact, drainage measures can also be considered according to specific circumstances.

[0032] Preferably, a baffle 16 is installed on the side of the hopper 13, and the baffle 16 is provided with a waist-shaped hole 17, in which a screw threadedly connected to the side of the hopper 13 is installed. With this design, the baffle 16 can control the amount of raw grain flowing out of the hopper 13, thereby controlling the grading efficiency. In fact, the structure for controlling the discharge efficiency can also be considered according to specific circumstances.

[0033] Preferably, the slideway 7 is installed obliquely on the grading bin 3. Such a design is conducive to the movement of the raw grain toward the discharge port 12. In fact, the angle of inclination can also be considered according to specific circumstances.

[0034] Preferably, there are at least three groups of slideways 7. Such a design ensures the number of graded levels. In fact, the number of slideways 7 can also be considered according to specific circumstances.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
