[0002] The grading and screening of corn is an important link in seed treatment and grain processing. The purpose is to classify corn kernels according to their size, shape, color and other physical characteristics to ensure the quality and consistency of the final product. By grading and screening, it is ensured that the seeds have a high germination rate and consistency, so as to achieve uniform growth of crops and increase the yield of crops; seeds of different sizes are suitable for different planting densities and depths, and the sowing strategy can be optimized through grading and screening.

[0003] Most of the existing corn grading and screening devices set multiple screens with different mesh sizes from top to bottom. The corn seeds are poured into the top layer, and the corn kernels are screened through the screens with different mesh sizes. Finally, the corn on different screens is classified and collected, so as to realize the grading and screening of corn seeds. In this way, after each screening, it is necessary to collect the corn kernels on different screens, which affects the screening efficiency and is inconvenient to operate during collection.

[0004] Based on this, it is necessary to design a fully automatic rapid grading device for corn seeds to realize the functions of efficient screening and classified collection of corn. Summary of the Utility Model

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: A fully automated rapid corn seed grading device, as Figures 1 - 3As shown in the figure, it includes a box body 1, a feeding frame 2, a support rod 3, an inverted L-shaped cover plate 4, a partition plate 7, a screening frame 8, and an electric slide rail two 10. On the left side of the top of the box body 1, a feeding frame 2 is arranged through a support rod 3. The feeding frame 2 is funnel-shaped. The bottom end of the feeding frame 2 is communicated with the inner cavity of the box body 1. The inner cavity of the box body 1 is divided into three storage chambers with accommodation spaces by a partition plate 7. The height of the partition plate 7 decreases successively from left to right. Three screening frames 8 for grading and screening corn seeds are arranged in the inner cavity of the box body 1. The screening frames 8 are gradually inclined downward from left to right. The space between two adjacent screening frames 8 is in a stepped shape with one high and one low. This stepped shape decreases successively from left to right. The way of being inclined downward from left to right and in a stepped shape facilitates the rolling of corn seeds from the left screening frame 8 to the right screening frame 8, realizing the function of automatically screening seeds without power; The screening frames 8 are arranged above the storage chambers. The mesh apertures of the screening nets of the screening frames 8 decrease successively from left to right. Thus, the corn grains screened out by the screening frames 8 from left to right are getting larger and larger. A second collection box 6 is slidably arranged at the bottom inside the box body 1. The second collection box 6 is arranged directly below the screening frame 8. The second collection box 6 is used to collect the corn seeds screened by the corresponding screening frame 8, realizing the function of classifying and collecting the screened corn seeds; Electric slide rails two 10 are symmetrically arranged on the front and rear sides of the top of the box body 1. An inverted L-shaped cover plate 4 is slidably arranged on the electric slide rails two 10. The front and rear sides of the inverted L-shaped cover plate 4 are in contact and fit with the top of the front and rear sides of the box body 1. The lower end of the right side of the inverted L-shaped cover plate 4 is in contact and fit with the top of the partition plate 7. The inverted L-shaped cover plate 4 is arranged above the screening frame 8. Thus, the corn seeds in the corresponding screening frame 8 are blocked on the corresponding screening frame 8, preventing corn seeds of different particles from falling into the non-corresponding second collection box 6 when moving from left to right, thereby ensuring the accuracy of classification and collection.

[0021] During use, the corn seeds are added to the screening frame 8 closest to the feeding frame 2 through the feeding frame 2. The corn grains with a diameter smaller than the mesh aperture of the screening frame 8 will fall into the second collection box 6 below it for collection, thereby realizing the primary screening of corn; Subsequently, the electric slide rail two 10 works to drive the inverted L-shaped cover plate 4 to move upward. The right end of the inverted L-shaped cover plate 4 is separated from the partition plate 7, thereby releasing the blockage of the corn. Since the three screening frames 8 in the box body 1 are inclined downward successively from left to right, therefore, the corn on the screening frame 8 will fall to the next screening frame 8 on the right. Then, the inverted L-shaped cover plate 4 moves downward to reset. By analogy, the corn is screened successively from left to right, so as to obtain corn seeds with consistent particle sizes. The seeds screened by the screening frame 8 fall into the corresponding second collection box 6 for collection.

[0022] As Figures 3 - 4As shown in the figure, it further includes a T-shaped rod 41, a wavy plate 801, a loosening rake 802, a connecting rod 803, a first electric slide rail 804, a spring 805, a guide rod 806 and a sliding block 807. The inverted L-shaped cover plate 4 is provided with a horizontal chute and the first electric slide rail 804 is arranged in the chute. The slider of the first electric slide rail 804 is slidably connected with the loosening rake 802 through the connecting rod 803. The T-shaped rod 41 is slidably connected to the inverted L-shaped cover plate 4. The lower end of the T-shaped rod 41 is connected with the sliding block 807. The sliding block 807 is slidably connected with one end of the loosening rake 802 away from the first electric slide rail 804. The teeth of the loosening rake 802 are made of soft material and the end part is curved. The loosening rake 802 is arranged above the screening box 8 and its teeth are in contact and cooperation with the screening box 8. A wavy plate 801 which is in intermittent extrusion cooperation with the teeth of the loosening rake 802 is arranged on the longitudinal inner wall of the inverted L-shaped cover plate 4. A guide rod 806 is slidably arranged between the slider of the first electric slide rail 804 and the top of the loosening rake 802. A spring 805 is arranged between the protrusion through which the top of the loosening rake 802 is slid through by the guide rod 806 and the end of the guide rod 806. When the first electric slide rail 804 drives the loosening rake 802 to perform horizontal movement back and forth, the teeth of the loosening rake 802 are extruded against the protrusions of the wavy plate 801, and the loosening rake 802 horizontally moves in the direction away from the first electric slide rail 804 and compresses the spring 805 deforming. When the teeth of the loosening rake 802 approach the recesses of the wavy plate 801, the spring 805 resets and the loosening rake 802 resets to the right. Through the back-and-forth and left-and-right horizontal movement of the loosening rake 802, the corns on the screening box 8 are loosened, thereby improving the screening efficiency.

[0023] When the first electric slide rail 804 works, the slider on the first electric slide rail 804 drives the loosening rake 802 to perform horizontal movement in the front and back directions through the connecting rod 803. Under the intermittent extrusion action of the teeth of the loosening rake 802 on the wavy plate 801 and with the cooperation of the guide rod 806 and the spring 805, the loosening rake 802 performs horizontal movement in the left and right directions between the connecting rod 803 and the sliding block 807, thereby loosening the corns on the screening box 8 to prevent them from piling up, thus improving the screening efficiency.

[0024] As Figure 1 and Figure 5 As shown in the figure, a fan 9 is installed at the rear side of the box body 1. The fan 9 is arranged below the screening box 8. A first collection box 5 is slidably arranged at the front side of the box body 1, and an air outlet is opened above the first collection box 5 and a wire mesh 501 is arranged at the air outlet.

[0025] When the fan 9 works, it blows the corn husks and debris falling from the screening box 8 into the corresponding first collection box 5 for collection.

[0026] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
