Description

Technical Field

[0001] The utility model relates to the technical field of seed screening, in particular to a seed sorting device used for grain planting. Background Art

[0002] Before sowing grain seeds, in order to select the best varieties, it is usually necessary to select large and full seeds for sowing. This is especially true for seeds such as peanuts, corn, and peas. Seeds that are not large or full enough not only have a low survival rate, but also due to genetic characteristics, the fruits produced by the seedlings after planting are relatively small.

[0003] Before agricultural sowing, seeds need to be screened to screen out the shriveled seeds, dust and pebbles inside the seeds. Most existing screening methods use wind power for screening, and wind screening uses air to blow out the shriveled seeds and dust inside the full seeds, but the impurities and dust contained in the seeds are difficult to discharge, resulting in incomplete screening. At the same time, when seeds of different sizes need to be screened, the screen needs to be constantly replaced, and after replacement, it needs to be repositioned and installed, affecting the screening efficiency. Utility Model Content

Baffles 212 are fixedly installed at both ends of the first sieve 21, and the baffles 212 can prevent seeds from splashing, thereby causing more seeds to be damaged.

[0021] During specific use, the utility model is a seed sorting device for grain planting. First, seeds are introduced through the feed port at the top of the sorting box 1, and then the motor 26 is driven. The motor 26 drives the circular plate 24 to rotate, the circular plate 24 drives the round rod 25 to rotate, the round rod 25 drives the slide plate 23 to do horizontal reciprocating motion, the slide plate 23 drives the slide bar 22 to do horizontal reciprocating motion, and the slide bar 22 drives the first screen 21 to do horizontal reciprocating motion, so that the first screen 21 can continuously perform shaking screening, further improving the screening efficiency, and through the action of the scraper 211 at the top of the first screen 21, the scraper 211 can scrape away the seeds blocked at the top of the first screen 21, so as to avoid the top of the first screen 21 being blocked and causing damage to the first screen 21.

[0022] Embodiment 2:

[0023] On the basis of the first embodiment, Figure 3 and Figure 4 As shown, the bottom end of the screening mechanism 2 is provided with an auxiliary mechanism 3 with an auxiliary screen 33, and the bottom end of the first screen 21 is provided with two auxiliary screens 33. The seeds can be screened synchronously multiple times through the separated auxiliary screens 33, thereby further improving the screening efficiency. The first screen 21 and the auxiliary screens 33 are tiltedly arranged inside the sorting box 1, and the first spring 31 and the second spring 32 are fixedly installed between the two auxiliary screens 33 and the first screen 21, respectively. The first spring 31 and the second spring 32 facilitate the reset of the auxiliary screen 33, thereby achieving screening of larger seed particles. An electric push rod 36 is fixedly installed on the inner bottom wall of the sorting box 1, and a push rod 35 is fixedly installed on the output end of the electric push rod 36. The push rod 35 A limit rod 34 is fixedly installed on the top of the auxiliary screen 21, and the limit rod 34 slides through the first screen 21, and a limit block is fixedly installed on the surface of the limit rod 34 at the bottom of the auxiliary screen 33. By moving the auxiliary screen 33, the sorting box 1 can quickly screen seeds of different sizes, further improving the screening efficiency. A guide plate 37 is fixedly installed on the inner wall of the sorting box 1, and the guide plate 37 is located between the auxiliary screen 33 and the electric push rod 36. A discharge pipe 4 and a waste pipe 5 are provided on the outer surface of the sorting box 1. The discharge pipe 4 is connected and installed at a position close to the first screen 21. Qualified seeds after screening can be discharged through the discharge pipe 4, and the waste pipe 5 is connected and installed at a position close to the guide plate 37. Waste can be discharged through the guide plate 37.

[0024] In specific use, the utility model is a seed sorting device for grain planting. When screening grain seeds, when screening larger seeds, the first screen 21 can be directly used for screening, so as to screen out larger qualified seeds, and the auxiliary screen 33 is kept away from the first screen 21 by the action of the first spring 31 and the second spring 32. At this time, the seeds can be screened multiple times synchronously through the separated auxiliary screen 33, so as to further improve the screening efficiency. When it is necessary to screen smaller seeds, the electric push rod 36 is started at this time. The electric push rod 36 drives the push rod 35 to move, and the limit rod 34 of the push rod 35 moves. The limit rod 34 drives the auxiliary screen 33 to move and compresses the first spring 31 and the second spring 32 through the action of the limit block, until the first screen 21 and the auxiliary screen 33 with the same mesh number are merged. Since the grids of the original first screen 21 and the auxiliary screen 33 are arranged in an alternating manner, the mesh number of the merged screen will be reduced at this time, thereby realizing the screening of smaller seeds, so that the sorting box 1 can quickly screen seeds of different sizes, thereby further improving the screening efficiency.
