[0022] Figure 1 Schematic diagram of a crop seed screening device provided by an embodiment of the utility model. Figure 1 , Figure 2 and Figure 4As shown, a crop seed screening device comprises a screening mechanism 1, a cleaning mechanism 2 is arranged on the outer side of the screening mechanism 1, the cleaning mechanism 2 is composed of a fixed seat 20, a support rod 21, a movable part 22, a limiting rod 23, a baffle 24, a top plate 25, a connecting strip 26, a brush head 27 and a reset spring 28, both ends of the support rod 21 are fixedly connected with the fixed seat 20, the front and back sides of the screening mechanism 1 are provided with support rods 21, the outer side of the support rod 21 is slidably connected with the movable part 22 located between the two fixed seats 20, the inner side of the movable part 22 is sleeved with the limiting rod 23, the bottom end of the limiting rod 23 is fixedly connected with the baffle 24, the top end of the baffle 24 is fixedly connected to the bottom of the top plate 25, the bottom of the top plate 25 is fixedly connected with the connecting strip 26, the bottom of the connecting strip 26 is fixedly connected with the brush head 27, and the movable part 22 and the baffle 24 are respectively welded to the two ends of the reset spring 28.

[0023] In this embodiment, it should be specifically explained that the function of the screening mechanism 1 is to screen the seeds and select high-quality seeds with large, full and neat grains. The function of the cleaning mechanism 2 is to clean the screen 15 and peel the seeds. When the screening mechanism 1 is screening the seeds, when some seeds are embedded in the screen 15, the top plate 25 can be pressed down to make the brush head 27 contact with the seeds in the screen 15. During the contact process, the top plate 25 is moved, and the brush head 27 will sweep out the embedded seeds. After cleaning, stop applying pressure to the top plate 25, and under the action of the reset spring 28, the connecting strip 25 is pressed down. 26 is reset to facilitate normal seed screening. The movable part 22 is T-shaped, and a limiting hole is provided on the movable part 22. The limiting hole and the limiting rod 23 are sleeved, which can limit the movement of the connecting strip 26 to avoid it from tilting during movement, so that the brush head 27 can accurately contact the seeds. The connecting strip 26 is located between the two limiting rods 23, and the length of the connecting strip 26 is less than the distance between the two side guard plates 13. The connecting strip 26 can make the brush head 27 fully contact with the screen 15 after being pressed down, thereby increasing the cleaning efficiency of the brush head 27 for seeds embedded in the screen 15.

[0024] like Figure 3 As shown, the screening mechanism 1 includes a material storage box 10, a material guide cover 11, a base 12, a side guard plate 13, a material guide hopper 14, a screen 15, a recovery container 16 and a handle 17. The top of the material storage box 10 is fixedly connected with the material guide cover 11, the bottom of the material storage box 10 is fixedly connected with the base 12, the top of the base 12 is fixedly connected with two side guard plates 13 located on the right side of the material storage box 10, the right side of the side guard plate 13 is fixedly connected with the material guide hopper 14, the top of the base 12 is provided with a feeding port, the interior of the feeding port is fixedly connected with the screen 15, the interior of the base 12 is slidably connected with the recovery container 16, and the left side of the recovery container 16 is fixedly connected with the handle 17.

[0025] In the present embodiment, it should be specifically explained that the inner side of the material guide cover 11 is designed to be inclined, so that the seeds can be quickly introduced into the storage box 10 when entering. The storage box 10 is connected to the material guide cover 11, and a discharge port is provided at the bottom of the right side of the storage box 10, so that the seeds in the storage box 10 can be introduced into the base 12. The two side guard plates 13 protect the seeds to prevent them from scattering. Since the top of the base 12 is an inclined surface, the poorly developed seeds can fall into the recovery container 16 in the base 12 under the action of the screen 15, and the high-quality seeds will be concentratedly discharged under the action of the material guide hopper 14. After the screening is completed, the recovery container 16 can be pulled out from the opening provided on the left side of the base 12 by pulling the handle 17 outward, which is also convenient for centralized processing of the poorly developed seeds.

[0026] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0027] The above specific implementations do not constitute a limitation on the protection scope of the present utility model. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
