Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, specifically a vegetable seed screening device for vegetable cultivation. Background Technology

[0002] Seeds are the reproductive bodies unique to gymnosperms and angiosperms, formed from ovules through pollination and fertilization. Seed formation allows the young sporophyte ovules to be protected by the parent plant and to receive sufficient nutrients, much like a mammalian fetus. Seeds also have structures suitable for dispersal or resistance to adverse conditions, creating favorable conditions for the continuation of the plant species. Vegetable seeds are used to produce vegetables. Vegetable seeds are selected through a series of cultivation and selection processes. During the selection process, sieving devices are used to remove impurities and bad seeds, thus selecting superior seeds to ensure the quality of vegetable seeds and guarantee vegetable yield.

[0003] However, most existing vegetable seeds that require screening lack multi-stage screening structures, resulting in low overall screening efficiency and limited practicality. Furthermore, screening often relies on the seed's own weight, which can easily cause blockages and reduce the screening device's efficiency. Therefore, a novel vegetable seed screening device for vegetable cultivation is needed to address these technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a vegetable seed screening device for vegetable cultivation, which has the advantages of multi-stage screening, anti-clogging and smooth screening, and solves the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vegetable seed sieving device for vegetable cultivation, comprising: a sieving box, a sieving container and a sliding frame slidably connected inside the sieving box; a connecting rod rotatably connected outside the sieving container; a turntable rotatably connected outside the connecting rod; a sieving motor fixedly connected outside the turntable; a screen fixedly connected inside the sliding frame; four sliding rods fixedly connected to the bottom of the sliding frame; sleeves fitted around the four sliding rods; a rotating rod rotatably connected inside the sieving box; striking rods evenly fixedly connected to the outside of the rotating rod; a drive motor fixedly connected to the end of the rotating rod; a collection box slidably connected inside the bottom of the sieving box; and a sorting window opened outside the sieving box. During sieving, seeds are first placed inside the sieving box, and then sieving is performed using the sieving motor... The machine drives the turntable to rotate, causing the connecting rod to rotate centrifugally along the outside of the turntable. This allows the connecting rod to push and pull the sieve box back and forth, further enabling the sieve box to slide back and forth inside the sieve chamber, achieving primary sieving of the seeds. Large particles of impurities are filtered and sorted out. Finally, the seeds and smaller dust particles fall onto the top of the screen for further sieving. When the seeds and fine dust enter the screen, the drive motor drives the rotating rod to rotate, which in turn drives the external striking rod to rotate. As the striking rod rotates, it repeatedly strikes the screen, causing the screen's synchronous sliding frame to vibrate up and down inside the sieve chamber. This further separates the seeds and fine dust particles inside, allowing the fine dust to pass through the screen and enter the collection box for collection. This achieves multi-stage sieving while avoiding the need to rely solely on gravity for sieving and clogging prevention.

[0006] Preferably, the sieving box slides horizontally inside the sieving box, the sliding frame slides vertically inside the sieving box, and the four sleeves are all fixedly connected to the inner wall of the sieving box. The sliding frame is located at the bottom of the sieving box. The sieving box can sieve large particles of impurities in the seeds, and the sieve can filter fine dust particles of impurities in the seeds, thus achieving a multi-stage sieving effect.

[0007] Preferably, the screening motor is fixedly connected to the outside of the screening box, and the connecting rod is rotatably connected to the outside of the turntable. The connecting rod is rotatably connected to the edge of the turntable, so that when the turntable rotates, the connecting rod can rotate centrifugally, realizing repeated pushing and pulling of the screening box.

[0008] Preferably, sliders are fixedly connected to the exterior of both sides of the sieving box, and two retaining sleeves are fixedly connected to the interior of the sieving box. The sliders are engaged inside the retaining sleeves, allowing the sieving box to slide back and forth inside the sieving box.

[0009] Preferably, the rotating rod shaft is connected inside the screening box, and the drive motor is fixedly connected to the outside of the screening box. The drive motor drives the rotating rod to rotate, and the rotating rod can drive the external striking rod to rotate, so that the striking rod can repeatedly strike the screen as the rotating rod rotates, thereby improving the screening efficiency of the screen.

[0010] Preferably, each of the four sleeves is fitted with a return spring, and the outside of the collection box is fixedly connected with a handle. The elastic force of the return spring can act in the opposite direction on the sliding rod, which can cause the screen to slide up and down inside the screening box, thereby improving the screening efficiency.

[0011] Preferably, the bottom of each of the four sliding rods is fixedly connected to a limiting plate, which is sleeved inside the sleeve. The limiting plate ensures that the sliding rod will not come out of the sleeve when it slides inside the sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] I. In the screening process of this utility model, the seeds are first put into the screening box. The screening motor drives the turntable to rotate, which causes the connecting rod to rotate centrifugally along the outside of the turntable. This allows the connecting rod to push and pull the screening box back and forth, and further allows the screening box to slide back and forth inside the screening box, thus achieving one screening of the seeds. Large particles of impurities can be filtered and sorted. Finally, the seeds and smaller dust particles fall into the top of the screen for further screening.

[0014] II. In this utility model, when seeds and fine dust enter the inside of the sieve, the drive motor drives the rotating rod to rotate, which in turn drives the external striking rod to rotate. When the striking rod rotates, it repeatedly strikes the sieve, causing the sieve's synchronous sliding frame to shake up and down inside the sieving box. This further separates the seeds and fine dust particles inside, allowing the fine dust to pass through the sieve and enter the collection box for collection. This achieves multi-stage sieving while avoiding the purpose of sieving and preventing clogging by relying solely on its own weight. Attached Figure Description

The connecting rod 7 is rotatably connected to the edge of the turntable 6, so that when the turntable 6 rotates, the connecting rod 7 can rotate centrifugally, realizing repeated pushing and pulling of the screening box 4.

[0025] Both sides of the screening box 4 are fixedly connected to sliders 10. The inside of the screening box 1 is fixedly connected to two sleeves 11. The sliders 10 are locked inside the sleeves 11, which allows the screening box 4 to slide back and forth inside the screening box 1.

[0026] The rotating shaft of the rotating rod 12 is connected to the inside of the screening box 1, and the drive motor 14 is fixedly connected to the outside of the screening box 1.

[0027] Each of the four sleeves 16 is fitted with a return spring 17. The collection box 2 is fixedly connected to a handle. The elastic force of the return spring 17 can act in the opposite direction on the slide rod 15, which can make the screen 9 slide frame 8 move up and down inside the screening box 1, thereby improving the screening efficiency.

[0028] When this vegetable seed screening device is in use, the screening motor 5 drives the turntable 6 to rotate, which causes the connecting rod 7 to rotate centrifugally along the outside of the turntable 6. This allows the connecting rod 7 to push and pull the screening box 4 back and forth, and further allows the screening box 4 to slide back and forth inside the screening box 1, thus achieving one-time screening of the seeds.
