Abstract
Description
[0001] This invention relates to the field of screening technology, and in particular to a screening device for Chinese cabbage seeds. Background Technology
[0002] Seed screening, one of the methods for cleaning crop seeds, uses seed sieves with different mesh sizes and shapes to remove impurities such as mud lumps, sand particles, seeds of other crops, weed seeds, insect galls, husks, chaff, and small seeds, retaining large, plump, and uniform high-quality seeds to improve seed quality. Screening machines are used to separate seeds of different sizes. A motor drives a reducer, which in turn drives a vibrator. The vibrator is equipped with a screen, and the seeds on the screen bounce due to the vibration. Seeds passing through the screen are classified, and the remaining seeds are screened again to select the better ones. Finally, the smaller, lower-quality seeds remain. Therefore, a seed screening device for Chinese cabbage is needed.
[0003] Therefore, patent publication number CN219464061 discloses a seed screening device, belonging to the technical field of seed screening devices. The screening device includes a housing with supporting feet on its sides and foot pads installed at the bottom of the supporting feet. A partition plate is installed inside the housing, and a sieve disc is installed above the partition plate. The sieve disc is connected to a sieve rod, the top of which is connected to the top of the housing.

[0007] In operation, seeds to be screened are first added to the screening box from the feed hopper. The suction component on one side of the third screen uses its own suction to draw dust from the seeds and empty seeds from the screening box into the dust collection box. At the same time, the first motor drives the rotating shaft to rotate, which in turn drives the gear at one end to rotate. The first gear drives the second gear to rotate, which in turn drives the third gear at the top to rotate. This causes the first top plate at one end of the gear to vibrate the third screen connector, thus causing the third screen to vibrate. Then, the hydraulic cylinder drives the plunger to move, which in turn drives the scraper at one end to move forward. Larger debris such as weeds are pushed from the third screen to the side of the fan, greatly increasing the efficiency of seed screening and removing debris from the seeds.

[0016] The advantages of the seed screening device for Chinese cabbage provided by this invention are as follows: by adding the seeds to be screened into the screening box through the inlet, the suction component on one side of the third screen is adjusted to suck the dust in the seeds and the empty seeds in the screening box into the dust collection box through its own suction force. At the same time, the first motor drives the rotating shaft to rotate, the rotating shaft drives the gear at one end to rotate, the first gear drives the second gear to rotate, and the third gear at the top to rotate, thereby driving the first top plate at one end of the gear to vibrate the third screen connecting part, thereby causing the third screen to vibrate. Then, the hydraulic cylinder drives the plunger to move, driving the scraper at one end to move forward. Larger debris such as weeds are pushed from the third screen to the side of the fan, which greatly increases the efficiency of seed screening and removes the debris in the seeds, thereby achieving the purpose of dust removal for the Chinese cabbage seed screening device. The second motor drives the rotating shaft to rotate, which in turn drives the roller at one end to rotate. A spring is installed at one end of the roller to increase the intensity of the vibration. The rotation of the roller drives the threaded rod at one end to rotate, which in turn drives the second top plate at the top to rotate. Since the second top plate is located between the first screen and the second screen, the rotation of the second top plate during the screening process causes the first screen and the second screen to vibrate simultaneously, which allows the Chinese cabbage seeds to be screened quickly and improves the screening efficiency. This achieves the purpose of improving the screening efficiency of the Chinese cabbage seed screening device. By installing a slot at one end of the screening box and setting a locking block at one end of the first and second screens, the first and second screens are connected by a connecting block and a connecting rod. When in use, simply pull the handle at one end of the connecting rod, and the screen will disengage from the slot at one end of the screening box, making it easy for the user to remove the screen. When installing the screen, simply insert the first and second screens directly into the slots at both ends of the integrated sleeve of the device. This disassembly and assembly method is more labor-saving and time-saving, and can greatly improve the disassembly efficiency of the screen, thereby achieving the purpose of convenient disassembly of the screen of the vegetable seed screening device.
