Description

Technical Field

[0001] This utility model relates to the technical field of double-selection machines, specifically a double-selection machine. Background Technology

[0002] The compound seed separator integrates functions such as hulling, air separation, screening, dust removal, and gravity grading. It is suitable for crops such as wheat, rice, and corn, and features high stability and low failure rate. Existing technology involves pouring seeds into a hopper, filtering out larger impurities with a filter screen, and then the seeds enter the separator's main body. A motor rotates, and a connecting rod drives the mixing blades to disperse the seeds. Heavier impurities are filtered through a first screen and fall into a dust collection hopper for collection. Pulling the hopper out from the base removes the impurities, achieving a uniform removal of debris from the seeds. However, the screening process primarily uses a sieve to select the crop seeds. When changing seeds, the corresponding compound seed separator is usually replaced directly, without replacing the sieve itself. This necessitates manufacturers equipping each crop with dedicated equipment, increasing initial investment and maintenance costs.

[0003] Therefore, we propose a double-selection machine. Utility Model Content

[0004] The purpose of this utility model is to provide a double-selection machine to solve the problem mentioned in the background art that when changing the seeds to be screened, the corresponding double-selection machine is usually replaced directly without replacing the screen in the double-selection machine, which makes manufacturers need to equip each crop with special equipment, increasing the initial investment and maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-stage sorting machine, comprising a base, a feeding hopper fixedly connected to the base, a suction pipe for suction inside the feeding hopper, one end of the suction pipe connected to a cyclone dust collector screening body, a discharge pipe on one side of the cyclone dust collector screening body, the discharge pipe connected to the top of a cover, a cylinder fixedly connected to the cover, a support frame at the bottom of the cylinder, multiple discharge pipes fixedly connected to the outside of the cylinder, a motor fixedly connected to the bottom of the cylinder, the motor output shaft inserted into a linkage shaft, a lever fixedly connected to the linkage shaft, multiple screen plates rotatably connected to the linkage shaft, a spring inside each screen plate, the spring tightly pressing against a limiting block, and a sealing plate above the spring.

[0006] Preferably, the inside of the cylinder is provided with a limiting block groove for engaging the limiting block, and the limiting block groove is inserted into and engaged with the limiting block.

[0007] Preferably, the limiting block is slidably connected inside the sieve plate, and the limiting block tightly presses against the sealing plate.

[0008] Preferably, the sealing plate is fixedly connected to the top of the sieve plate, and the sealing plate is provided with a locking block, which tightly presses against the limiting block.

[0009] Preferably, one end of the linkage shaft is connected to a bearing, and the outer ring of the bearing is frictionally connected to the cylinder.

[0010] Preferably, the linkage shaft has a groove, which engages with the lever.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features a limiting block groove inside the cylinder for positioning the distance between screen plates. The limiting block groove engages with multiple limiting blocks inside the screen plate, and is tightly secured by springs. This ensures a stable connection between the screen plate and the cylinder. A sealing plate prevents material from entering between the spring and the limiting block, causing blockage and preventing movement. This makes it easy to replace the screen plate and reduces the cost for manufacturers to equip each crop with dedicated equipment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example

[0019] Please see Figures 1-3 The diagram shows a double-stage screening machine, including a base 1. A feeding hopper 2 is fixedly connected to the base 1. A suction pipe 3 for material suction is located inside the feeding hopper 2. One end of the suction pipe 3 is connected to a cyclone dust collector screening body 4. A discharge pipe 5 is located on one side of the cyclone dust collector screening body 4. The discharge pipe 5 is connected to the top of a cover 6. The cover 6 is fixedly connected to a cylinder 7. A support frame 701 is located at the bottom of the cylinder 7. Multiple discharge pipes 702 are fixedly connected to the outside of the cylinder 7. A motor 8 is fixedly connected to the bottom of the cylinder 7. The output shaft of the motor 8 is inserted into a linkage shaft 9. The linkage shaft 9 is fixedly connected to a lever 10. The linkage shaft 9 rotates... Multiple screen plates 11 are dynamically connected. Each screen plate 11 is equipped with a spring 12 inside. The spring 12 tightly presses against the limiting block 13. A sealing plate 14 is provided above the spring 12. This utility model uses a limiting block groove inside the cylinder to position the distance between the screen plates. The limiting block groove engages with multiple limiting blocks inside the screen plate, and the spring tightly limits the blocks, ensuring the stability of the connection between the screen plate and the cylinder. The sealing plate prevents material from entering between the spring and the limiting block and causing blockage, thus preventing the screen plates from moving. This makes it easy to replace the screen plates and reduces the cost for manufacturers to equip each crop with special equipment.

[0020] Furthermore, the cyclone dust collector screening body 4 generates negative pressure suction, which draws the material into the suction pipe through the feed hopper. The material rotates at high speed inside the cyclone dust collector screening body 4 and is separated into layers by centrifugal force.

[0021] Furthermore, the inside of the cylinder 7 is provided with a limiting block groove for engaging the limiting block 13. The limiting block groove is inserted into and engaged with the limiting block 13. The cylinder is provided with a groove inside to position the distance between the screen plates and to facilitate the connection between the cylinder and the screen plates.

[0022] Furthermore, the limiting block 13 is slidably connected to the inside of the screen plate 11, and the limiting block 13 tightly presses against the sealing plate 14. Through the cooperation of the limiting block and the sealing plate, the stability of the limiting block in the movement of the screen plate is ensured, as well as the stability of the screen plate in the movement.

[0023] Furthermore, the sealing plate 14 is fixedly connected to the top of the screen plate 11, and the sealing plate 14 is provided with a locking block 1401. The locking block 1401 tightly presses against the limiting block 13, thereby preventing the limiting block from sliding out of the screen plate.

[0024] Furthermore, one end of the linkage shaft 9 is connected to a bearing 15, the outer ring of the bearing 15 is frictionally connected to the cylinder 7, and the inner ring of the bearing is frictionally connected to the linkage shaft to ensure the stability of the linkage shaft under the drive of the motor.

[0025] Furthermore, the linkage shaft 9 has a groove that engages with the lever 10. The groove on the linkage shaft allows for quick determination of the lever's installation position and facilitates the separation of the linkage shaft from the bearing.

[0026] In this solution, the workflow is as follows: Ensure the equipment is completely stopped, use special calipers or a flathead screwdriver to separate the cover and the cylinder, use special calipers or a flathead screwdriver to pry open the sealing plate 14, and then separate the lever 10 from the linkage shaft 9.

[0027] Use calipers to clamp or pry the limiting block 13 to disengage it from the groove of the sieve plate 11, thus releasing the locking state.

[0028] Take out the sieve plate 11 and the lever 10 from the outside to the inside of the cylinder 7.

[0029] Insert the new sieve plate back into its original position, ensuring that the sealing plate 14 fits tightly against the inner wall of the cylinder 7.

[0030] The compression spring 12 embeds the limiting block 13 into the inner wall of the cylinder 7 of the screen plate 11, making it fit tightly against the groove of the limiting block.
