Description

Technical Field

[0001] The invention relates to the technical field of soybean screening, and in particular to an intelligent screening device for soybean seeds. Background Art

[0002] Crop breeding is also known as variety improvement. High yield, stable yield, high quality and high efficiency are the goals of breeding. However, specific breeding goals must take into account the current status of local varieties, breeding basis, natural environment, farming system, cultivation level, economic conditions and other factors, and be adjusted continuously with the development of production. It is also necessary to use several varieties with large planting areas or representative varieties in the region as standards, clarify the directions that need to be maintained or improved, improved or overcome, and make breeding goals specific.

[0003] Soybean seed cultivation usually involves screening the seeds and selecting high-quality soybean seeds for cultivation. At this time, a screening device is needed to screen the soybeans.

[0004] A soybean screening and breeding device for agricultural planting disclosed in Chinese patent CN211802408U includes a base, a groove is opened inside the base, a screening mechanism is fixedly installed in the middle of the inner bottom wall of the groove, a guide plate 1, a guide plate 2 and a guide plate 3 are fixedly installed on the inner bottom wall of the groove, a support plate is fixedly installed on the inner bottom wall of the groove, and the left ends of the guide plate 1 and the guide plate 2 are fixedly connected to the right side surface of the support plate.

[0005] However, compared with the prior art and the comparative scheme, it can be seen that the screening device still has the following problems in actual use:

[0006] In the process of screening out inferior varieties such as moldy, shriveled, broken grains, and impurities such as bean stems and seed coats in existing spiral screens, gravity is generally used to make the soybeans roll and fall on the spiral plate. Under the action of centrifugal force, soybeans with larger mass and rounder shape roll to the outside of the spiral plate, while inferior varieties such as moldy, shriveled grains, and impurities such as bean stems and seed coats with lower mass and irregular shape are less affected by the centrifugal force and slide downward on the inside of the spiral plate, thus completing the separation of some inferior varieties and impurities in the soybeans. However, broken grains that are partially cracked but not completely broken are similar in quality and shape to normal soybean seeds and will be mixed with normal soybeans, making it difficult to separate them, thus affecting the screening effect. Summary of the invention

The number of the openings 211 is multiple, and the multiple openings 211 are respectively arranged at the connection between the connecting tube 201 and the second material guide plate 205 and the collecting plate 206;

[0037] like Figure 1 , Figure 2 , Figure 3 and Fig. 9 As shown, the rotating assembly 3 includes a rotating shaft 301, a toggle plate 302 and a transmission wheel 303. The rotating shaft 301 is rotatably connected to the connecting tube 201. The rotating shaft 301 is arranged between adjacent first material guide plates 204. The rotating shaft 301 is provided with a toggle plate 302. The toggle plates 302 are arranged in a circular array on the rotating shaft 301. The toggle plates 302 are adapted to the adapting groove 210. A transmission wheel 303 is arranged at one end of the rotating shaft 301. The transmission wheel 303 is arranged inside the connecting tube 201.

[0038] like Figure 2 , Figure 3 , Fig.10As shown, the circulation component 4 includes a spiral plate 401, a circulation pipe 402 and a driven wheel 403. The circulation pipe 402 is arranged at one end of the spiral plate 401, and the driven wheel 403 is arranged on the circulation pipe 402.

[0039] The working process is as follows:

[0040] S1: When in use, soybeans are added into the upper hopper 202, and fall onto the first guide plate 204 from the lower opening 203 on the upper hopper 202, and move downward along the first guide plate 204;

[0041] S2: When passing through the adjacent first guide plate 204, since the rotating assembly 3 is arranged between the adjacent guide plates, the soybeans push the shifting plate 302 during the movement, the shifting plate 302 drives the rotating shaft 301 to rotate, the rotating shaft 301 drives the transmission wheel 303 to rotate, the transmission wheel 303 drives the circulation pipe 402 through the driven wheel 403, and the circulation pipe 402 drives the spiral plate 401 to rotate;

[0042] S3: During the movement of the soybeans on the first guide plates 204, due to the height difference between the adjacent first guide plates 204, when the soybeans pass through the rotating assembly 3 and fall onto the subsequent first guide plates 204, the partially cracked but not completely broken particles collide with the subsequent first guide plates 204 due to the height difference, so that the partially cracked but not completely broken particles are broken into irregular shapes due to the collision;

[0043] S4: The soybeans and inferior varieties and impurities in the soybeans fall onto the second guide plate 205 along the first guide plate 204. In the process of moving downward along the second guide plate 205, the soybeans with larger mass and more rounded shapes and the broken grains that are partially cracked but not completely broken are thrown outward from the second guide plate 205 under the action of centrifugal force and fall onto the collecting plate 206, while inferior varieties such as moldy and shrunken grains with lower mass and irregular shapes and impurities such as bean stems and seed coats are less affected by the centrifugal force and slide downward on the inner side of the second guide plate 205;

[0044] S5: As the inferior soybeans such as moldy and shrunken beans, impurities such as bean stems and seed coats, and partially adulterated normal soybeans move along the second guide plate 205, part of them enter the connecting pipe 201 from the opening 211, and part of them are discharged from the first discharge port 208 along the second guide plate 205. The part of soybeans entering the connecting pipe 201 moves upward with the rotation of the spiral plate 401, and enters the upper hopper 202 along the circulation pipe 402 to be screened again;

[0045] S6: When normal soybeans and partially cracked but not completely broken grains fall on the collecting plate 206, they collide with the collecting plate 206, so that the partially cracked but not completely broken grains are completely broken into irregularly shaped grains, and the centrifugal force on the grains is relatively small;

[0046] S7: When the collecting plate 206 slides up and down, the crushed particles slide downward on the inner side of the collecting plate 206, and the crushed particles enter the connecting pipe 201 at the opening 211, enter the upper hopper 202 along the circulation pipe 402, and are discharged from the first discharge port 208 along the first guide plate 204 and the second guide plate 205;

[0047] S8: The complete soybeans slide downward along the outer side of the collecting plate 206 and are discharged at the second discharge port 209, thereby completing the separation of normal soybean seeds from inferior seeds such as moldy and shrunken seeds and impurities such as bean stems and seed coats.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
