Description

Technical Field

[0001] The utility model relates to the technical field of air separators, in particular to a wheat seed air separator. Background Art

[0002] Wheat is a general term for plants of the genus Triticeae, and its representative species is common wheat, which is a grass plant and a cereal crop widely grown all over the world. The caryopsis of wheat is one of the staple foods of humans. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. When breeding wheat, it is necessary to air-select the wheat seeds to screen out the unfull wheat seeds and grade the wheat seeds according to the fullness of the wheat seeds. For example, the patent with publication number CN217094437U discloses a wheat grading air-selection device, including an air-selection box, one side of which is provided with an exhaust port; a feeding hopper, which is arranged on the top of the air-selection box; a feeding pipe, which is arranged at the bottom of the feeding hopper; three air-selection collection boxes, which are fixedly installed at the bottom of the air-selection box; three discharge pipes, which are respectively arranged at the bottom of the three air-selection collection boxes, and the bottom ends of the three discharge pipes extend to the outside of the air-selection box; and three material valves, which are respectively arranged on the three discharge pipes. The device feeds wheat seeds into a winnowing box through a feeding hopper for winnowing. However, when feeding, a large amount of wheat seeds will enter the winnowing box, resulting in poor winnowing effect, thereby affecting the grading of the wheat seeds.

[0003] To this end, the utility model provides a wheat seed winnowing machine. Utility Model Content

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a wheat seed air separator, including an air separator body 1, a sieve cylinder 12 is rotatably fitted in the air separator body 1, an anti-blocking structure is fixed in the air separator body 1, the anti-blocking structure corresponds to the sieve cylinder 12, a fan 3 is fixed on one side of the air separator body 1, an air outlet 4 is opened on the other side of the air separator body 1, a plurality of baffles 5 are fixed at the bottom in the air separator body 1, a plurality of discharge openings 6 are opened at the bottom in the air separator body 1, and a damper 7 is fixed on one side of the air separator body 1 close to the air outlet 4.

[0022] In this embodiment, a support base 9 is fixed on one side of the air separator body 1, a motor 10 is fixed on the support base 9, and the output end of the motor 10 is fixedly connected to the sieve cylinder 12.

[0023] The sieve cylinder 12 can be driven to rotate by the motor 10, so that the wheat seeds in the sieve cylinder 12 can fall dispersedly, preventing the wheat seeds from accumulating together and directly entering the air separator body 1 for air separation.

[0024] A support ring 8 is fixed on one side of the air outlet 4, the cross section of the support ring 8 is an L-shaped structure, an air inlet 2 is opened on the side of the air separator body 1 opposite to the air outlet 4, and the fan 3 is fixed on one side of the air inlet 2.

[0025] A collection bag can be installed through the support ring 8. When air separation is carried out, the fan 3 is started, and the fan 3 blows air into the air separator body 1 through the air inlet 2, and then the collection bag can filter the blown air and collect the dust in the wheat seeds to prevent air pollution.

[0026] The discharge opening 6 is located between two adjacent baffles 5, and the discharge opening 6 is a conical structure.

[0027] Specifically, when air separation is carried out, wheat seeds of different weights will be blown to different positions by the wind, and the wheat seeds fall into different discharge openings 6, so that the wheat seeds can be classified.

[0028] There are two mounting frames 11 fixed inside the air separator body 1. The mounting frames 11 are rotatably connected to the sieve cylinder 12. The anti-blocking structure includes a fixing rod 15. A plurality of bristles 16 are fixed on the fixing rod 15. The bristles 16 are hard bristles. The bristles 16 are in contact with the sieve cylinder 12. The fixing rod 15 is fixed between the two mounting frames 11.

[0029] Specifically, when wheat seeds are put in while rotating, at this time, the bristles 16 are inserted into the sieve holes of the top sieve cylinder 12, so that the sieve holes can be dredged, thereby preventing the sieve cylinder 12 from being blocked.

[0030] The mounting frame 11 is of a triangular structure. The sieve cylinder 12 is inclined and arranged inside the air separator body 1. One side of the air separator body 1 is fixed with a feed pipe 13. One end of the feed pipe 13 is rotatably connected to the sieve cylinder 12. The other end of the feed pipe 13 is fixed with a feed funnel 14.

[0031] Specifically, when wheat seeds are put in, the wheat seeds are put into the feed funnel 14, and then the wheat seeds enter the sieve cylinder 12 through the feed pipe 13. As the sieve cylinder 12 rotates, the wheat seeds can be sent into the air separator body 1, and then air separation can be carried out.
