Abstract
Description
Technical Field
[0001] This utility model relates to the field of impurity removal technology, specifically to a sieving and impurity removal device for seed processing. Background Technology
[0002] Grains, including rice, wheat, millet, and soybeans, are mainly plant seeds and fruits and are a traditional staple food for many Asian people. In order to ensure the germination rate of grain seeds during the cultivation process, grain seeds need to be screened in order to cultivate high-quality grain seeds.
[0003] A wind-separation seed selection and processing device disclosed in authorization announcement number CN221657177U includes a wind-separation box. The top of the wind-separation box is connected to a feed hopper, the right side of the wind-separation box is connected to a discharge pipe, a collection box is slidably connected inside the wind-separation box, and the left side of the wind-separation box is connected to a discharge pipe extending into the interior of the wind-separation box. A C-shaped plate is fixedly connected to the left side of the wind-separation box. A wind-separating fan sorts the seeds entering the wind-separation box, thus performing preliminary screening of impurities such as leaves mixed in with the seeds. Simultaneously, the impurities are discharged through the discharge pipe. A connecting rod, driven by the rotation of an eccentric disc, causes the screen plate to shake. With the cooperation of four elastic plates, the screen plate automatically resets, thereby vibrating and screening the seeds on the screen plate, further removing particles and stones from the seeds and separating unqualified small seeds, thus improving the seed selection process. However, when using the above device, the speed of adding seeds needs to be manually controlled. If too many seeds are added in a short period, the sorting effect will be reduced.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Please see Figures 1-4A seed processing screening and impurity removal device includes an air classifier body 1 and a motor 2. The upper surface of the air classifier body 1 is connected to a feeding pipe 3, and a baffle 4 is rotatably connected to the inner wall of the feeding pipe 3. A material groove 5 is opened on the outer wall of the baffle 4, and a connecting shaft 6 is fixedly connected to one end of the baffle 4.

By setting the worm gear 7, worm 8 and rotating shaft 9 to work together, when the motor 2 starts, the motor 2 can drive the rotating shaft 9 to rotate through the connecting adjustment component. The rotating shaft 9 can drive the connecting shaft 6 to rotate through the worm 8 and worm gear 7. The rotating connecting shaft 6 drives the baffle 4 to rotate, thus completing the stable feeding.

By setting the first multi-stage pulley 11 and the second multi-stage pulley 12 to work together, when the motor 2 starts, the motor 2 can drive the second multi-stage pulley 12 to rotate, and the rotating second multi-stage pulley 12 drives the first multi-stage pulley 11 and the rotating shaft 9 to rotate through the transmission belt 13.
[0023] Furthermore, both the first multi-stage pulley 11 and the second multi-stage pulley 12 are composed of multiple pulleys of different sizes fixed together. By setting the first multi-stage pulley 11 and the second multi-stage pulley 12, which are composed of pulleys of different sizes, the position of the transmission belt 13 can be adjusted to adjust the rotation speed of the motor 2 driving the rotating shaft 9, thereby adjusting the stable feeding speed.
[0024] Furthermore, a protrusion 15 is rotatably connected to one end of the rotating shaft 9, and the protrusion 15 is fixedly connected to the air separator body 1; by setting the protrusion 15, one end of the rotating shaft 9 can be supported, increasing the stability of the rotation of the rotating shaft 9.
