[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] 1. The utility model provides a screening device for crop seeds. After the seeds are added to the top of the main body, they first contact the screening mechanism, and the seeds are accumulated on the screen of the screening mechanism. The screening mechanism is driven to move back and forth by the driving mechanism to screen the seeds.

[0017] 3. The utility model provides a screening device for crop seeds. The screening mechanism reciprocates to screen the seeds. The screened seeds fall downward onto the conveyor belt of the discharging mechanism. The industrial fan inhales external air and blows in the direction of the partition net, so that the seeds falling onto the conveyor belt pass through the air duct. Hollow seeds and seeds that are not full enough are lighter than qualified full seeds. Therefore, they are blown to the side of the partition net when passing through the air duct, and are blown out of the screening device through the partition net.

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] like Figure 1 As shown, the utility model provides a screening device for crop seeds, including a main body 1, a screening mechanism 3 is arranged on the top of the main body 1, one end of the screening mechanism 3 is fixedly connected to a driving mechanism 2, and a discharging mechanism 4 is arranged on the bottom of the main body 1.

[0026] like Figure 2 As shown, the utility model provides a technical solution: preferably, the screening mechanism 3 includes a base plate 34, the base plate 34 is slidably limited and inserted into a limit plate 33, a screen 32 is fixedly installed on the limit plate 33, a handle 31 is fixedly installed at one end of the limit plate 33, the screening mechanism 3 is slidably clamped in the top of the main body 1, and is fixedly connected to the driving mechanism 2 through the base plate 34.

[0027] In this embodiment, after the seeds are added to the top of the main body 1, they first contact the screening mechanism 3, and the seeds are accumulated on the screen 32 of the screening mechanism 3. The screening mechanism 3 is driven back and forth by the driving mechanism 2 to screen the seeds. When the screen 32 is blocked, or when another batch of seeds of different specifications and sizes need to be screened, the screen 32 can be directly pulled out from one side of the base plate 34 through the handle 31 and the limiting plate 33, and the screen 32 can be cleaned or replaced with screens 32 of different specifications. The flexible and adjustable screening mechanism 3 can adapt to the screening needs of different seeds for different crop types and different planting requirements.

[0028] like Figure 3 As shown, the utility model provides a technical solution: preferably, the driving mechanism 2 includes a slide rail 24, a slider 23 is slidably connected to the slide rail 24, a connecting rod 22 is rotatably installed on one side of the slider 23, the slider 23 is connected to the motor 21 through the connecting rod 22, the slide rail 24 is fixedly installed on the inner wall of the main body 1, and one side of the screening mechanism 3 is fixedly connected to the slider 23.

[0029] In this embodiment, the motor 21 drives one end of the connecting rod 22 to rotate, so that the connecting rod 22 pulls the slider 23 at the other end to slide back and forth on the slide rail 24. One side of the screening mechanism 3 is fixedly connected to the slider 23, thereby driving the screening mechanism 3 to reciprocate to screen the seeds, and the screened seeds fall downward into the discharging mechanism 4.

[0030] like Figure 4-5 As shown, the utility model provides a technical solution: preferably, the discharging mechanism 4 includes an industrial fan 41, and the discharging mechanism 4 also includes a partition net 43 and a conveyor belt 42, the conveyor belt 42 is located below the partition net 43 and the industrial fan 41, and the partition net 43 is located opposite to the industrial fan 41.

[0031] In this embodiment, the screening mechanism 3 reciprocates to screen the seeds, and the screened seeds fall downward onto the conveyor belt 42 of the discharging mechanism 4. The industrial fan 41 sucks in external air and blows in the direction of the partition net 43, so that the seeds falling downward onto the conveyor belt 42 pass through the air duct. The hollow seeds and seeds that are not full are lighter than the qualified full seeds, so they are blown to the side of the partition net 43 when passing through the air duct, and are blown out of the screening device through the partition net 43. The seeds that finally fall onto the conveyor belt 42 are all qualified full seeds. The screening device for crop seeds is convenient for replacing the screen, has the functions of wind selection and conveying, has strong functional integration, can meet the needs of modern agricultural production, improve the efficiency and quality of seed screening, and thus promote the development of agricultural production.

[0032] The working principle of the screening device for crop seeds will be specifically described below.

[0033] like Figure 1-5As shown, after the seeds are added to the top of the main body 1, they first contact the screening mechanism 3, and the seeds are accumulated on the screen 32 of the screening mechanism 3. The screening mechanism 3 is driven back and forth by the driving mechanism 2 to screen the seeds. When the screen 32 is blocked, or when another batch of seeds of different specifications and sizes need to be screened, the screen 32 can be directly pulled out from one side of the base plate 34 through the handle 31 and the limiting plate 33, and the screen 32 can be cleaned or replaced with screens 32 of different specifications. The flexible and adjustable screening mechanism 3 can adapt to the screening needs of different seeds for different crop types and different planting requirements and seeds of different specifications. The motor 21 drives one end of the connecting rod 22 to rotate, so that the connecting rod 22 pulls the slider 23 at the other end to slide back and forth on the slide rail 24, and one side of the screening mechanism 3 is fixedly connected to the slider 23, thereby driving the screening mechanism 3 reciprocates to screen the seeds, and the screened seeds fall downward into the discharging mechanism 4. The screening mechanism 3 reciprocates to screen the seeds, and the screened seeds fall downward onto the conveyor belt 42 of the discharging mechanism 4. The industrial fan 41 inhales external air and blows in the direction of the partition net 43, so that the seeds falling downward onto the conveyor belt 42 pass through the air duct. The hollow seeds and the seeds that are not full are lighter than the qualified full seeds, so they are blown to the side of the partition net 43 when passing through the air duct, and are blown out of the screening device through the partition net 43. The seeds that finally fall onto the conveyor belt 42 are all qualified full seeds. The screening device for crop seeds is convenient for replacing the screen, has the functions of wind selection and conveying, has strong functional integration, can meet the needs of modern agricultural production, improve the efficiency and quality of seed screening, and thus promote the development of agricultural production.
