Description

Technical Field

[0001] The utility model belongs to the technical field of vegetable planting, and in particular relates to a seed screening device. Background Art

[0002] When planting vegetables, in order to improve the quality of seeds, screening devices are needed to screen out impurities (mud, sand and gravel, seeds of other crops, weed seeds, galls, husks, etc.), blighted grains and small seeds in the seeds, and select high-quality seeds that are large, full and neat.

[0003] The screening device screens out small seeds and inclusions by the size of the screen mesh. Different seeds use different screens (for example, the screen mesh for screening broad beans is larger than that for screening edamame). In the prior art, the screen is fixed inside the screening device, which is inconvenient to replace the screen according to the size of the seeds to be screened, thereby reducing the flexibility of the device when used. Therefore, a technical measure is proposed to solve the problem that in the prior art, the screen is fixed inside the screening device, which is inconvenient to replace the screen according to the size of the seeds to be screened, thereby reducing the flexibility of the device when used.

When the seeds move, the vibration motor 8 drives the sieve plate 14 to vibrate, so that the seed screening efficiency is improved. When the seeds move, small seeds raise the sieve holes 17 and enter the lower part of the box body 1, and then the small seeds fall through the discharge port 7, and qualified seeds fall into the discharge plate 5. A collecting bucket is provided below the discharge plate 5 to collect the seeds. When the vibration motor 8 is working, the vibration force is transmitted to the connecting plate 6, and then transmitted to the mounting plate 11 and the first spring 18 through the connecting plate 6. The first spring 18 absorbs the vibration force. When the sieve plate 14 needs to be replaced, the connecting assembly 2 is used to take out the sieve plate 14 as a whole and replace it with a new sieve plate 14.

[0026] Reference Figure 1 , Figure 2 and Figure 4As shown, the connection assembly 2 includes a connection block 201, and the connection block 201 has two groups. The lower parts of the two groups of connection blocks 201 are fixedly connected to the sieve plate 14. The connection block 201 is T-shaped, and a limiting hole 203 is provided on the upper part of the connection block 201. A round hole 202 is provided on the lower part of the connection block 201.

[0027] Working principle: When using the device to screen seeds, the seeds are placed in the feed box 12, and then the vibration motor 8 is started. When the vibration motor 8 is started, the draw plate 19 is pulled upward synchronously, and the draw plate 19 moves upward to release the seed blockade, and the seeds fall into the sieve plate 14, and the seeds roll down along the sieve plate 14. When the seeds move, the vibration motor 8 drives the sieve plate 14 to vibrate, so that the seed screening efficiency is improved. When the seeds move, small seeds increase the sieve hole 17 and enter the lower part of the box body 1, and then the small seeds fall through the discharge port 7, and the qualified seeds fall into the discharge plate 5. A collection bucket is set below the discharge plate 5 to collect the seeds. The combination of the draw plate 19 and the current limiting frame 13 facilitates the control of the seed falling amount.

[0028] When the vibration motor 8 is working, the vibration force is transmitted to the connecting plate 6, and then transmitted to the mounting plate 11 and the first spring 18 through the connecting plate 6. The first spring 18 absorbs the vibration force, thereby reducing the overall vibration amplitude of the machine;

[0029] When the sieve plate 14 needs to be replaced, the connecting component 2 is used to take out the sieve plate 14 as a whole and replace it with a new sieve plate 14. The specific method is to press the pressing plate 208, and the pressing plate 208 moves horizontally to drive the pressure plate 205 to move horizontally. The pressure plate 205 moves horizontally to compress the second spring 204, and the pressure plate 205 moves horizontally to drive the vertical plate 206 to move horizontally. The vertical plate 206 moves horizontally to drive the insertion rod 207 to move horizontally. The insertion rod 207 moves horizontally and disengages from the socket 16. Then, the connecting block 201 is lifted upward to drive the sieve plate 14 to disengage from the box body 1, and then the new sieve plate 14 is installed. Through the setting of the connecting component 2, the movable connection between the sieve plate 14 and the box body 1 is realized, so that the sieve plate 14 can be flexibly replaced according to the size of the seeds, and the replacement operation is convenient, which improves the flexibility of the device when used.
