Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, and in particular to a corn seed screening and sorting device. Background Technology

[0002] As a globally important food crop, the quality of corn seeds directly affects crop growth and yield. During natural harvesting, corn seeds are often affected by impurities, pests, diseases, or substandard seeds, resulting in low germination rates after sowing and even impacting the final harvest. Therefore, corn seed sorting technology has emerged to improve seed quality through precise sorting, effectively increase production efficiency, reduce planting costs, improve seed utilization, and ensure crop growth and yield.

[0003] Publication number CN221361018U discloses a corn seed sorting device, including a top plate, a feed inlet at the upper end of the top plate, a feed hopper at the feed inlet, a feeding mechanism below the feed hopper, a fixing block at the lower end of the top plate, a screening device connected to the fixing block, support columns around the lower end of the top plate, a connecting frame connected to the lower end of the support columns, and a shaking device for shaking the screening device at the upper end of the connecting frame.

[0004] This device uses a shaking mechanism. Activating the telescopic push rod moves the adjusting block left and right along the strip plate, causing the roller to move up and down on the adjusting block. The roller then drives the sliding rod to move up and down on the support frame, which in turn drives the square plate to move the feeding box up and down, thus shaking the feeding box. This allows the sorting device to process large quantities of corn seeds quickly and accurately, improving processing efficiency. However, while the sieve separates large particles from the corn seeds, smaller particles and broken corn seeds pass through the sieve together, resulting in incomplete screening. Furthermore, the large particles contain broken straw and other easily tangled impurities, which can clump together during vibration, causing blockages inside the device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a corn seed screening and sorting device.

[0006] The present invention is achieved by the following technical solution: a corn seed screening and sorting device, including a support block, an air separation mechanism is provided on the top of the support block, and a screening mechanism is provided on the surface of the air separation mechanism; The air separation mechanism includes a blower, an air supply pipe is fixedly connected to the output end of the blower, a discharge pipe is fixedly connected to the inner wall of the air supply pipe, a baffle is fixedly connected to the inner wall of the air supply pipe near the blower, an installation cylinder is fixedly connected to the end of the air supply pipe away from the blower, and a through pipe is rotatably connected to the inner wall of the installation cylinder.

[0007] The above technical solution, by setting up a baffle, can effectively prevent corn seeds from falling into the fan during the falling process, thus ensuring the reliability of the device.

[0008] As a further improvement to the above solution, the surface of the fan is fixedly connected to the top of the support block.

[0009] As a further improvement to the above solution, the mounting cylinder and the through pipe are set at a horizontal inclination of 5°.

[0010] The above technical solution involves setting up a fan, which generates airflow to blow out lighter impurities through an inclined pipe, while denser seeds remain in the pipe for sieving, thus preventing light impurities such as straw from clogging the sieve holes.

[0011] As a further improvement to the above solution, the screening mechanism includes a mounting block, a motor fixedly connected to the top of the mounting block, a sieve hole opened in the inner wall of the through pipe, a gear ring fixedly connected to the surface of the through pipe, a planetary gear meshing on the tooth surface of the gear ring, a connecting rod fixedly connected to the inner wall of the planetary gear, a wing plate fixedly connected to the surface of the connecting rod, an inner cylinder fixedly connected to the inner wall of the wing plate, a connecting box plate fixedly connected to the inner wall of the inner cylinder, and a collection box fixedly connected to the bottom of the connecting box plate.

[0012] As a further improvement to the above solution, the surface of the mounting block is fixedly connected to the surface of the mounting cylinder, and the output end of the motor is fixedly connected to one end of the connecting rod.

[0013] As a further improvement to the above scheme, the gear ring and planetary gears are provided in two sets, symmetrically arranged at both ends of the through pipe.

[0014] Through the above technical solution, by setting a gear ring and planetary gears, the motor drives the planetary gears and connecting rods. The meshing transmission between the gear ring and the planetary gears smoothly drives the through pipe with screen holes to rotate continuously. Smaller stones and broken seeds pass through the screen holes and fall into the collection box, while full seeds continue to fall and are discharged from the discharge pipe, ensuring the effectiveness of the device.

[0015] As a further improvement to the above solution, the surface of the wing plate is fixedly connected to the inner wall of the mounting cylinder, and the surface of the connecting box plate is fixedly connected to the inner wall of the mounting cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features an air-separation mechanism, specifically a fan. The airflow generated by the fan blows lighter impurities out through an inclined pipe, while denser seeds remain in the pipe for sieving. This prevents light impurities such as straw from clogging the sieve holes. By installing a baffle at the fan's output end, the corn seeds are effectively prevented from falling into the fan during the falling process, ensuring the reliability of the device.

[0017] This invention features a screening mechanism, specifically a gear ring and planetary gears. A motor drives the planetary gears and connecting rods, and the meshing transmission between the gear ring and the planetary gears smoothly drives the through-tube with sieve holes to rotate continuously. Smaller stones and broken seeds pass through the sieve holes and fall into the collection box, while fuller seeds continue to fall and are discharged from the outlet pipe, ensuring the effectiveness of the device.

[0021] Please combine Figure 1-5 The corn seed screening and sorting device of this embodiment includes a support block 1, an air separation mechanism 2 is provided on the top of the support block 1, and a screening mechanism 3 is provided on the surface of the air separation mechanism 2. The air separation mechanism 2 includes a blower 201. An air supply pipe 202 is fixedly connected to the output end of the blower 201. A discharge pipe 203 is fixedly connected to the inner wall of the air supply pipe 202. A baffle 204 is fixedly connected to the inner wall of the air supply pipe 202 near the blower 201. The baffle 204 at the output end of the blower 201 can effectively prevent corn seeds from falling into the blower 201 during the falling process. An installation cylinder 205 is fixedly connected to the end of the air supply pipe 202 away from the blower 201. A through pipe 206 is rotatably connected to the inner wall of the installation cylinder 205.

[0022] The surface of the fan 201 is fixedly connected to the top of the support block 1. The airflow generated by the fan 201 blows out lighter impurities through the inclined pipe 206, while the denser seeds remain in the pipe 206 for screening, thus preventing light impurities such as straw from clogging the sieve holes 303.

[0023] The mounting cylinder 205 and the through pipe 206 are set at a horizontal tilt of 5°.

[0024] The screening mechanism 3 includes a mounting block 301, a motor 302 fixedly connected to the top of the mounting block 301, a sieve hole 303 opened on the inner wall of the through pipe 206, a gear ring 304 fixedly connected to the surface of the through pipe 206, a planetary gear 305 meshing on the tooth surface of the gear ring 304, a connecting rod 306 fixedly connected to the inner wall of the planetary gear 305, a wing plate 307 fixedly connected to the surface of the connecting rod 306, an inner cylinder 308 fixedly connected to the inner wall of the wing plate 307, a connecting box plate 309 fixedly connected to the inner wall of the inner cylinder 308, and a collection box 310 fixedly connected to the bottom of the connecting box plate 309. The motor 302 drives the planetary gear 305 and the connecting rod 306, and the meshing transmission between the gear ring 304 and the planetary gear 305 smoothly drives the through pipe 206 with sieve holes 303 to rotate continuously. Small stones and broken seeds pass through the sieve holes 303 and fall into the collection box 310.

[0025] The surface of the mounting block 301 is fixedly connected to the surface of the mounting cylinder 205, and the output end of the motor 302 is fixedly connected to one end of the connecting rod 306.

[0028] The implementation principle of the corn seed screening and sorting device in this embodiment is as follows: When in use, the motor 302 is started to drive the planetary gear 305 and the connecting rod 306. The meshing transmission between the gear ring 304 and the planetary gear 305 smoothly drives the tube 206 with sieve holes 303 to rotate continuously. Seeds are thrown into the device from the top of the tube 206. Small stones and broken seeds pass through the sieve holes 303 and fall into the collection box 310. At the same time, the airflow generated by the blower 201 blows out the lighter impurities through the inclined tube 206, while the denser seeds remain in the tube 206 for screening, avoiding the blockage of the sieve holes 303 by light impurities such as straw. The baffle 204 at the output end of the blower 201 can effectively prevent corn seeds from falling into the blower 201 during the falling process. Full seeds continue to fall and are discharged from the discharge pipe 203, ensuring the effectiveness of the device.
