Abstract
Description
Technical Field
[0001] This utility model relates to the field of cabbage seed impurity removal technology, specifically to a cabbage seed impurity removal device. Background Technology
[0002] Cabbage seeds are usually round or nearly round, with a flat appearance and a diameter of about 2-4 mm. This shape helps them to move and take root easily in the soil. They come in a variety of colors, including yellow, brown, and black, and the surface is usually smooth, but sometimes there may be some lines or depressions.
[0003] However, during the processing and storage of cabbage seeds, impurities such as soil, weed seeds, withered leaves, and pebbles may be present. These impurities may carry pathogens, insect eggs, or harmful substances. When they come into direct contact with cabbage seeds, they may cause mold, pests, or chemical contamination, reducing the germination rate and seedling survival rate. Furthermore, the presence of weed seeds can compete for soil nutrients, affecting the growth of cabbage seedlings. Therefore, a device for removing impurities from cabbage seeds is needed during the processing and storage of cabbage seeds. Utility Model Content
[0004] This utility model addresses the technical problems existing in the prior art by providing a device for removing impurities from cabbage seeds.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cabbage seed impurity removal device includes a support frame, a separation component is provided at the upper end of the support frame, a feed hopper is fixedly installed at the rear end of the separation component and a discharge hopper is fixedly installed at the left end of the separation component and at the upper end of the support frame; the separation component includes a fixing plate fixedly installed at the right end of the support frame, a sealing cover is fixedly connected to the left end of the fixing plate, an outer cylinder is rotatably connected to the left end of the sealing cover, a plurality of equidistant holes are opened on the inner wall of the outer cylinder, an inner cylinder is provided inside the outer cylinder, a limiting ring is fixedly connected to the left end of the inner cylinder, a plurality of equidistant connecting rods are fixedly connected to the left end of the limiting ring, and the left ends of the plurality of connecting rods are all fixedly connected to a fixing plate fixedly installed at the left end of the support frame.
[0006] Furthermore, a first gear is fitted onto the outer wall of the outer cylinder.
[0007] Furthermore, a first motor is fixedly connected to the left end of the fixing plate, and a second gear that meshes with the first gear is fixedly connected to the transmission end of the first motor.
[0008] Furthermore, the right end of the sealing cover is fixedly connected to a feed pipe that communicates with the inside of the outer cylinder, and the end of the feed pipe away from the sealing cover is connected to the feed hopper.
[0009] Furthermore, a second motor is fixedly connected to the right end of the fixed disk, and a spiral rod that passes through the limiting ring and extends into the inner cylinder is fixedly connected to the transmission end of the second motor.
[0010] Furthermore, the top of the discharge hopper is provided with a guide groove adapted to the outer cylinder.
[0011] Furthermore, a matching inner cylinder receiving groove is provided at the top of the discharge hopper and on the left side of the guide chute.
[0012] Furthermore, the inner cylinder is V-shaped and the bottom of the inner cylinder is rounded.
[0013] The beneficial effects of this utility model are:
[0014] 1. The centrifugal force generated by the rotation of the outer cylinder, combined with the friction and guidance of the material by the grooves on the inner wall, and the pushing action of the screw rod while the inner cylinder remains stationary, forms a dual-effect separation mechanism. Due to the difference in physical properties, seeds and impurities separate rapidly in relative motion. Fine impurities are discharged with the outer cylinder, while pure seeds are directionally conveyed by the screw rod. The impurity removal rate is high, effectively ensuring seed purity.
[0015] 2. Through the integrated design of the feeding hopper, separation components and discharge hopper, combined with the stable operation mode of gear transmission and motor drive, the seed processing process is simplified. The guide chute and receiving chute are precisely connected to the outlet of the outer cylinder and the inner cylinder, realizing automatic material diversion and reducing manual intervention.

[0027] Support 1: Provides stable support, ensures that the positions of each component are fixed, and facilitates material transfer and separation operations;
[0028] Feed hopper 2 and discharge hopper 3: respectively realize the input of seeds and the output of separated materials, forming a complete processing flow;
[0029] Outer cylinder 403 holes: used for seed embedding. When the outer cylinder 403 is rotated, seeds will be embedded in the holes on the inner wall of the outer cylinder 403. Round or nearly round cabbage seeds are embedded in the holes and are carried to a certain height as the drum rotates. Then, due to gravity, they fall into the inner cylinder 411. Irregularly shaped impurities (such as fragments, flat square stones) cannot be embedded in the holes and slide along the inner wall of the drum to the end and are discharged.
[0030] Inner cylinder 411 and fixed plate 409: The inner cylinder is fixed to the fixed plate by the connecting rod 410 to keep it stationary and is used to receive seeds that fall from the holes of the outer cylinder 403.
[0031] The outer wall of the outer cylinder 403 is fitted with the first gear 404;
[0032] First gear 404: As a transmission component, it is easy to connect to an external power source to drive the outer cylinder 403 to rotate and provide power for the separation process.

[0034] The first motor 405 drives the second gear 406 to rotate, and the second gear 406 drives the first gear 404 to rotate, thereby achieving stable rotation of the outer cylinder 403 and ensuring continuous operation of the separation process.
[0035] The right end of the sealing cover 402 is fixedly connected to a feed pipe 407 that communicates with the inside of the outer cylinder 403. The end of the feed pipe 407 away from the sealing cover 402 is connected to the feed hopper 2.
[0036] Feed pipe 407 and sealing cover 402: The sealing design prevents material leakage and guides the seeds smoothly from the feed hopper 2 into the inner cylinder 403, ensuring that the feeding process is controllable.
[0037] The right end of the fixed plate 409 is fixedly connected to a second motor 412, and the transmission end of the second motor 412 is fixedly connected to a spiral rod 413 that passes through the limiting ring 408 and extends into the inner cylinder 411.
[0038] The second motor 412 and the screw rod 413: The screw rod rotates inside the inner cylinder 411, which can push the material to move axially, thereby conveying the separated seeds from one end of the inner cylinder to the discharge hopper 3.
[0039] Limiting ring 408: Fixes the position of the inner cylinder 411, ensuring the stability of the inner cylinder 411 when the spiral rod 413 rotates, and preventing shaking from affecting the seed export effect.
[0040] The top of the discharge hopper 3 is provided with a guide groove adapted to the outer cylinder 403;
[0041] The feed chute is designed to match the size of the outer cylinder 403, guiding materials separated from the outer cylinder, such as impurities or large particles, to fall smoothly into the discharge hopper 3, preventing spillage or accumulation.
[0042] A receiving groove for the inner cylinder 411 is provided at the top of the discharge hopper 3 and on the left side of the guide chute.
[0043] Receiving trough: Aligned with the outlet of the inner cylinder 411, ensuring that the pure seeds separated in the inner cylinder are pushed directly into the discharge hopper 3 by the screw rod, thereby achieving the separation and collection of impurities and seeds.
[0044] The inner cylinder 411 is V-shaped and the bottom of the inner cylinder 411 is rounded.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
