[0018] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] The following further elaborates on a seed screening device of the present utility model in conjunction with the attached drawings.

[0020] Combined with the attached Figures 1-4 , the present utility model is introduced in detail.

[0021] A seed screening device includes a support frame 1, a screening drum 2 and a driving motor 3; a receiving container 4 is arranged below the screening drum 2 for collecting the screened seeds. The support frame 1 includes a bottom support 5 and a motor support 6. A drum mounting ring 7 is provided at the top of the bottom support 5, and the side wall of the screening drum 2 is rotatably connected to the drum mounting ring 7. The motor support 6 extends upward from one side of the bottom support 5 and bends and then extends above the main body of the screening drum 2. A controller 8 electrically connected to the driving motor 3 is provided on the motor support 6. The driving motor 3 is fixed on the motor support 6 and connected to the screening drum 2 to drive its rotation.

[0022] The screening drum 2 is a conical drum, and its bottom extends horizontally above the bottom support 5. The large-mouth end of the conical drum is the seed inlet, and the small-mouth end is the seed outlet. The screening drum 2 is a mesh drum, and the mesh holes on the mesh drum gradually increase from the seed inlet end to the seed outlet end for grading screening according to the seed size.

[0023] In an embodiment of the present application, a plurality of receiving containers are provided and arranged in sequence from the seed inlet end to the seed outlet end for collecting seeds of different sizes.

[0024] In order to more conveniently introduce seeds into the screening drum 2, a guiding cylinder 9 rotatably connected to the screening drum 2 is provided at the seed inlet end of the screening drum 2. The opening of the guiding cylinder 9 is inclined upward to facilitate the smooth entry of seeds into the screening drum 2.

[0025] In order to stably drive the rotation of the screening drum 2, a belt groove 10 is provided around the circumferential direction of the side wall of the screening drum 2, and the driving motor 3 drives the screening drum 2 to rotate by connecting the belt groove 10 through a belt 11.

[0027] The specific implementation process of a seed screening device of the present utility model is as follows:

[0028] In actual use, the seeds to be screened are poured into the guiding cylinder 9, and the seeds enter the screening drum 2 through the guiding cylinder 9. The driving motor 3 is started through the controller 8, and the driving motor 3 drives the screening drum 2 to rotate through the belt 11. The seeds roll in the screening drum 2 as the drum rotates. Since the screening drum 2 is conical and the bottom is in a horizontal state, during the rotation of the screening drum 2, the seeds will gradually move forward; due to the gradually increasing mesh holes, seeds of different sizes will fall into the lower receiving containers through different mesh holes respectively, realizing the grading screening of the seeds.

[0029] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
