[0035] The first screening mechanism 2 includes a first screening box 201, a water inlet pipe 202 and a water outlet pipe 204 provided on the first screening box 201, and a stirring mechanism 8 provided inside the first screening box 201. The water outlet pipe 204 is located in the upper middle portion of the side wall of the first screening box 201.

[0036] Four brackets 1 are provided at the lower end of the first screening mechanism 2 and the brackets 1 are located at the four corners, wherein the second screening mechanism 3 is located at the upper end of the first screening mechanism 2; a discharge port 6 is installed on the lower end surface of the first screening box 201, and the discharge port 6 is convenient for discharging;

[0037] Specifically, by setting up four brackets 1, good support can be provided for the device. By setting up the first screening mechanism 2, the seeds screened inside the second screening mechanism 3 can be collected and screened for the second time, thereby improving the screening efficiency.

[0038] Reference Figure 1 、 Figure 2 A hopper 7 is provided at the upper end of the feed port; the setting of the hopper 7 is convenient for feeding raw materials.

[0039] Reference Figure 3 、 Figure 4A fixed plate 308 is provided on one side of the inner wall of the second screening box 309, a limit rod 306 is installed on the upper end of the fixed plate 308, the screen plate 304 is slidably set on the limit rod 306 through the screening frame 303 and the movable plate 305, and a connecting block 302 is provided at the lower end of the vibration motor 301; a spring 307 is sleeved on the outer circumference of the limit rod 306, and the spring 307 is located between the movable plate 305 and the fixed plate 308;

[0040] Specifically, a vibration motor 301 is provided and a connecting block 302 is fixedly provided at the output end. The connecting block 302 shakes and screens the screen plate 304 at the bottom of the screening frame 303 through the vibration of the vibration motor 301, and two fixed plates 308 are provided to support the screening frame 303 and the movable plate 305. The spring 307 and the bottom of the limit rod 306 are fixed to the fixed plate 308, and the top of the spring 307 is fixed to the movable plate 305. When the vibration motor 301 drives the screen 304 to shake, the force of the spring 307 can make the shaking amplitude larger. Through shaking and screening, larger particles and seeds can remain on the upper end of the screen plate 304, and qualified seeds of the same size fall into the first screening mechanism 2 for water screening.

[0046] Specifically, the casing 801 can provide support and protection for the driving motor 802 inside, the output end of the driving motor 802 is connected with the stirring shaft 803, which can drive the stirring shaft 803 and the stirring blades 804 to stir, so that the seeds in the first screening box 201 are fully and uniformly stirred with the brine, and the seeds that are lighter and drier float on the water, which is convenient for removal.

[0047] The scheme disclosed in the present application sets the water inlet pipe 202 and the water outlet pipe 204, and the brine in the water tank 5 enters the first screening box 201 through the first water pump 203 and the second water pump 205, and the stirring shaft 803 and the stirring blades 804 are driven by the driving motor 802 to stir the inside of the first screening box 201, so that the seeds that are lighter, not fully developed, worm-eaten and cannot develop into seedlings float in the water tank 5, and are discharged to the collecting mechanism 4 through the water outlet pipe 204, avoiding waste, and qualified seeds can be discharged by finally opening the discharge port 6;

[0048] The scheme disclosed in the present application drives the connecting block 302 to pull and shake the screen plate 304 through the vibration motor 301, and sets the spring 307 to make the amplitude of the screen plate shaking larger, so that the qualified seeds of a certain size can enter the inside of the first screening box 201 through the screen plate 304, and the combination of the screen and the water screen can screen according to the size and specific gravity of the seeds at the same time, improving the comprehensiveness and accuracy of screening.
