Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0029] like Figures 1-6 As shown, a breeding screening device includes a loading component 1 that can respectively guide the screened seeds and impurities out of the device, a screening component 2 for sustainable and efficient seed screening is provided in the loading component 1, and a feeding component 3 that can guide the seeds to be screened into the screening component 2 is provided on one side of the loading component 1.

[0030] In this embodiment: the loading component 1 includes a frame 101, and a discharge rack 102 is fixedly connected to the bottom side of the frame 101; the frame 101 provides an installation position for components such as the discharge rack 102, the hanger 201, and the motor 210 to ensure the stable operation of the device, and the discharge rack 102 receives seeds or impurities contained in the seeds that fall from different positions of the screening component 2.

[0031] In this embodiment: the screening assembly 2 includes a rotating member that can rotate continuously to fully screen the seeds, a flow blocking member that can enable the seeds injected into the rotating member to move stably laterally, and a driving member that can enable the rotating member to rotate as needed, the rotating member includes a hanger 201 fixedly installed in the frame 101, a first barrel 202 is movably connected between the hangers 201, a first filter screen 203 is fixedly installed on the outer side of the first barrel 202, a second barrel 204 is fixedly installed in the first barrel 202, a fixing frame 205 is fixedly connected to one side of the first barrel 202, and a second filter screen 206 is fixedly installed on the outer side of the second barrel 204, the flow blocking member includes a first spiral blocking piece 207 fixedly connected to the inner side of the first barrel 202, and a second spiral blocking piece 208 is fixedly connected to the inner side of the second barrel 204, the driving member includes a gear ring 209 fixedly connected to the outer side of the first barrel 202, a motor 210 is fixedly installed in the frame 101, and the output end of the motor 210 is fixedly connected to the driving gear 211;

[0032] The hanger 201 is rotatably connected to the first barrel 202. The first filter screen 203 and the second filter screen 206 are both integrally formed with filter holes. The filter hole diameter of the first filter screen 203 is smaller than the filter hole diameter of the second filter screen 206. The ring gear 209 is meshed with the driving gear 211.

[0033] The first barrel 202 is installed by the hanger 201 so that the first barrel 202 can rotate stably under the action of external power, the seeds or impurities falling to the inner side of the first barrel 202 can be screened through the first filter 203, the seeds injected by the feeding component 3 are received by the second barrel 204, and the position change of the second barrel 204 connected to the first barrel 202 at one end in the device is further restricted by the fixing frame 205, so that the first barrel 202 and the second barrel 204 remain coaxial, and the seeds or impurities falling to the inner side of the first barrel 202 can be screened through the first filter 203. The net 206 screens the seeds that fall into the second barrel 204, and prevents the seeds that fall between the inner side of the first barrel 202 and the outer side of the second barrel 204 from flowing horizontally too quickly or accumulating somewhere without moving horizontally through the first spiral blocking piece 207. The second spiral blocking piece 208 prevents the seeds that fall into the second barrel 204 from flowing horizontally too quickly or accumulating somewhere without moving horizontally. The rotation of the output end of the motor 210 is transmitted to the first barrel 202 through the driving gear 211 and the ring gear 209.

[0034] In this embodiment: the feeding assembly 3 includes a feed hopper 301 fixedly installed on one side of the frame 101, and a material guide pipe 302 is fixedly connected to the bottom of the feed hopper 301; the seeds to be screened are placed in the feed hopper 301, and the seeds injected into the feed hopper 301 are introduced into a certain depth in the second barrel 204 through the material guide pipe 302.

[0035] Working principle: When the device is installed and used for breeding and screening, the motor 210 drives the first barrel 202 to rotate relative to the hanger 201 through the driving gear 211 and the ring gear 209, and the seeds to be screened are continuously fed into the feed hopper 301;

[0036] Under the action of gravity, the seeds in the feed hopper 301 will enter the second barrel 204 through the guide tube 302. Since the first barrel 202 rotates continuously and the second spiral blocking piece 208 can prevent the seeds from moving sideways in an disordered manner, the seeds will fully contact the second filter screen 206 in the second barrel 204 that rotates with the first barrel 202, and qualified seeds and smaller impurities will pass through the second filter screen 206 and fall between the first barrel 202 and the second barrel 204. Impurities that cannot pass through the second filter screen 206 will be trapped in the second barrel 204 and, under the action of the second spiral blocking piece 208 that rotates with the second barrel 204, leave the second barrel 204 from the end of the second barrel 204 away from the guide tube 302 until they fall into the separated right area of ​​the unloading rack 102 and leave the device.

[0037] Similarly, the first filter screen 203 will screen the seeds and impurities that fall to the surface, and retain the seeds with a particle size that meets the breeding requirements in the first barrel 202, and allow the unqualified seeds and impurities with smaller particle sizes to fall to the separated left area of ​​the unloading rack 102 and then leave the device. The seeds with a particle size that meets the requirements will be moved horizontally to the fixed rack 205 under the action of the first spiral blocking plate 207 that rotates with the first barrel 202, and after passing through the fixed rack 205, fall to the separated middle area of ​​the unloading rack 102 and then leave the device.

[0038] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of technicians in the relevant technical field without departing from the purpose of the present invention.
