Description

Technical Field

[0001] The utility model relates to the technical field of seed screening, in particular to a screening device for highland barley seeds. Background Art

[0002] Seed screening equipment is a special device that uses mechanical or airflow power to remove various impurities mixed in the seed group and seeds that do not meet quality requirements based on the differences in physical properties between seeds and impurities, thereby obtaining high-quality seeds.

[0003] A Chinese patent discloses a seed screening machine (authorization announcement number CN109719030A). This patented technology can classify seeds into three categories according to their size, and the screening standards are unified, with high screening efficiency. It liberates traditional manual labor, solves the problems of inconsistent and error-prone manual screening standards, and is conducive to large-scale screening work.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the highland barley seed screening devices on the market lack effective seed falling flow control devices. When the user inadvertently puts an excessive amount of highland barley seeds into the screening device, these seeds will quickly accumulate in the screening basket, forming a pile phenomenon. This pile-up hinders the smooth movement of the seeds during the screening process, thereby affecting the efficiency and accuracy of the screening, making it difficult to effectively separate high-quality seeds from defective products. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing technology has the disadvantage that the seed screening equipment screening basket will produce piles of materials. For this reason, we propose a screening device for highland barley seeds.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a screening device for highland barley seeds, comprising a seed screening machine body, a screening basket is installed inside the seed screening machine body, a feed trough is installed on the top of the seed screening machine body, and adjustment grooves are provided on both sides of the feed trough. The inside of the feed trough is slidably connected with a flow control plate, and the bottom ends of both sides of the flow control plate are fixedly connected with a limiting block, the inside of the adjustment groove is slidably connected to the surface of the limiting block, and a movable groove is provided on both sides of the feed trough, and the inside of the movable groove is slidably connected with a transmission rod, and the side of the transmission rod close to the flow control plate is fixedly connected with a fixed block, and several fixed grooves are provided on both sides of the flow control plate, and the inside of the fixed groove is slidably connected to the surface of the fixed block, and the other side of the transmission rod is fixedly connected with a control block.

[0007] Preferably, both ends of the adjustment groove are provided with a first sliding groove, both ends of the limit block are fixedly connected with a first sliding block, and the surface of the first sliding block is slidably connected to the inside of the first sliding groove.

[0008] Preferably, a first spring is slidably connected to the surface of the transmission rod, and a side of the first spring close to the control block is fixedly connected to the control block, and a side of the first spring close to the discharge chute is fixedly connected to the discharge chute.

[0009] Preferably, a second sliding groove is provided at both ends of the movable groove, and a second sliding block is fixedly connected to both ends of the transmission rod, and the interior of the second sliding groove is slidably connected to the surface of the second sliding block.

[0010] Preferably, movable grooves are provided on both sides of the screening basket, a cleaning brush is slidably connected to the inside of the movable groove, two fixed plates are fixedly connected to one side of the screening basket, the top and bottom ends of one side of the cleaning brush are provided with mounting grooves, a second spring is fixedly connected to the inside of the mounting groove, one end of the second spring is fixedly connected to a fixing button, a through hole is provided on the surface of the fixing plate, and the surface of the fixing button is slidably connected to the inside of the through hole.

[0011] Preferably, the surface of the fixing button is fixedly connected to a limiting ring, and the interior of the mounting groove is slidably connected to the surface of the limiting ring.

[0012] Preferably, the inner diameter of the fixing groove and the outer diameter of the fixing block are matched to each other.

[0013] The technical effects and advantages of this utility model are:

[0014] In the present invention, the transmission rod is moved to drive the fixed block to move out from the inside of the fixed groove, thereby releasing the fixation between the flow control plate and the discharge trough. At this time, the flow rate of the seed discharge and screening can be adjusted by moving the discharge trough up and down. After the adjustment is completed, the fixed block is moved back to the inside of the fixed groove to complete the fixation again. By setting the discharge trough, we can achieve multi-gear precise adjustment of the seed flow rate. This setting effectively prevents unnecessary accumulation on the screening layer due to excessive amount of seeds put in at one time. The accumulation will not only hinder the smooth flow of seeds, but also seriously affect the efficiency and accuracy of screening.

[0015] In the utility model, the fixing button is moved out from the inside of the through hole by pressing the fixing button, thereby releasing the fixed position of the cleaning brush. After use, the cleaning brush is reset, and the elasticity of the second spring will automatically push the fixing button back to the inside of the through hole, thereby fixing the position of the cleaning brush. When the cleaning brush is set in the screening basket for seed screening, the screening holes on the surface of the screening basket are often blocked by seeds. The setting of the cleaning brush can quickly clean out the seeds blocked in the screening holes, thereby improving the screening efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of fixed grooves 13 are provided on both sides of the flow control plate 5, and the inside of the fixed groove 13 is connected to the surface of the limiting block 6. The surface of the fixed block 9 is slidably connected, and the control block 10 is fixedly connected to the other side of the transmission rod 8. By moving the transmission rod 8, the transmission rod 8 drives the fixed block 9 to move out from the inside of the fixed groove 13, thereby releasing the fixation between the flow control plate 5 and the discharge trough 3. At this time, the flow rate of the seed discharge and screening can be adjusted by moving the discharge trough 3 up and down. After the adjustment is completed, the fixed block 9 is moved back to the inside of the fixed groove 13 to complete the fixation again. By setting the discharge trough 3, we can achieve multi-gear precise adjustment of the seed flow rate. This setting effectively prevents unnecessary accumulation on the screening layer due to excessive amount of seeds put in at one time. The accumulation will not only hinder the smooth flow of seeds, but also seriously affect the efficiency and accuracy of screening.

[0025] Reference Figure 2 and Figure 3 As shown, in this embodiment: a first slide groove 11 is provided at both ends of the adjustment groove 4, and a first slider 12 is fixedly connected to both ends of the limit block 6. The surface of the first slider 12 is slidably connected to the inside of the first slide groove 11. By making the first slider 12 slide inside the first slide groove 11, the movement of the flow control plate 5 can be made more stable when the flow control plate 5 is moved and adjusted, and at the same time, the moving position of the flow control plate 5 is limited to ensure that the flow control plate 5 will not derail or move out of the slot.

[0026] Reference Figure 2 and Figure 4 As shown, in this embodiment: the surface of the transmission rod 8 is slidingly connected with a first spring 14, the side of the first spring 14 close to the control block 10 is fixedly connected to the control block 10, and the side of the first spring 14 close to the discharge chute 3 is fixedly connected to the discharge chute 3. By setting the first spring 14, the elasticity of the first spring 14 can pull the control block 10, so that the control block 10 will not drive the transmission rod 8 to move easily due to shaking and accidental collision, ensuring that the fixed block 9 is stable inside the fixed groove 13.

[0027] Reference Figure 4As shown, in this embodiment: second sliding grooves 15 are provided at both ends of the movable groove 7, and second sliders 16 are fixedly connected at both ends of the transmission rod 8. The interior of the second sliding groove 15 is slidably connected to the surface of the second slider 16. By sliding the second slider 16 inside the second sliding groove 15, it can be ensured that the transmission rod 8 moves to a predetermined position and does not rotate during movement, thereby ensuring the stability of the transmission rod 8 during movement.

[0028] Reference Figure 5 and Figure 6 As shown, in this embodiment: movable grooves 17 are provided on both sides of the screening basket 2, and a cleaning brush 18 is slidably connected inside the movable groove 17. Two fixed plates 19 are fixedly connected to one side of the screening basket 2. The top and bottom ends of one side of the cleaning brush 18 are provided with mounting grooves 20. A second spring 21 is fixedly connected inside the mounting groove 20. One end of the second spring 21 is fixedly connected to a fixing button 22. A through hole 23 is provided on the surface of the fixing plate 19. The surface of the fixing button 22 is slidably connected to the inside of the through hole 23. By pressing the fixing button 22, the fixing button 22 is moved out from the inside of the through hole 23, thereby releasing the position fixation of the cleaning brush 18. After use, the cleaning brush 18 is reset, and the elasticity of the second spring 21 will automatically push the fixing button 22 back to the inside of the through hole 23, thereby fixing the position of the cleaning brush 18. By setting the cleaning brush 18, when the screening basket 2 is used for seed screening, the screening holes on the surface of the screening basket 2 are often blocked by seeds. The setting of the cleaning brush 18 can quickly clean out the seeds blocked in the screening holes, thereby improving the screening efficiency.

[0029] Reference Figure 6 As shown, in this embodiment: the surface of the fixing button 22 is fixedly connected to the limiting ring 24, and the interior of the mounting groove 20 is slidably connected to the surface of the limiting ring 24. By setting the limiting ring 24, the moving position of the fixing button 22 can be ensured, so that the fixing button 22 will not move out from the interior of the mounting groove 20, nor will it be pushed out of the mounting groove 20 due to the elasticity of the second spring 21.

[0030] Reference Figure 2 As shown, in this embodiment: the inner diameter size of the fixing groove 13 is adapted to the outer diameter size of the fixing block 9. By making the outer diameter size of the fixing block 9 and the inner diameter size of the fixing groove 13 adapted to each other, the fixation between the flow control plate 5 and the discharge chute 3 can be made more stable, and the flow control system can be made more precise.

[0031] Working principle: by moving the transmission rod 8, the transmission rod 8 drives the fixed block 9 to move out from the inside of the fixed groove 13, thereby releasing the fixation between the flow control plate 5 and the discharge trough 3. At this time, the flow rate of the seed feeding and screening can be adjusted by moving the discharge trough 3 up and down. After the adjustment is completed, the fixed block 9 is moved back to the inside of the fixed groove 13 to complete the fixation again. By setting the discharge trough 3, we can achieve multi-gear precise adjustment of the seed flow rate. This setting effectively prevents unnecessary accumulation on the screening layer due to excessive amount of seeds put in at one time. The accumulation not only It will hinder the smooth flow of seeds and seriously affect the efficiency and accuracy of screening. By making the first slider 12 slide inside the first slide groove 11, the movement of the flow control plate 5 can be made more stable when the flow control plate 5 is moved and adjusted. At the same time, the moving position of the flow control plate 5 is limited to ensure that the flow control plate 5 will not derail or move out of the slot. By setting the first spring 14, the elasticity of the first spring 14 can pull the control block 10, so that the control block 10 will not drive the transmission rod 8 to move easily due to shaking and accidental collision, ensuring that the fixed block 9 is stable inside the fixed groove 13. By making the second slider 16 slide inside the second slide groove 15, it is ensured that the transmission rod 8 moves to the predetermined position without rotating during movement, thereby ensuring the stability of the transmission rod 8 during movement. By pressing the fixing button 22, the fixing button 22 is moved out from the inside of the through hole 23, thereby releasing the position fixation of the cleaning brush 18. After use, the cleaning brush 18 is reset, and the elasticity of the second spring 21 automatically pushes the fixing button 22 back to the inside of the through hole 23, thereby fixing the position of the cleaning brush 18. By setting the cleaning brush 18, when the screening basket 2 is used for seed screening, Sometimes the screening holes on the surface of the screening basket 2 are blocked by seeds. The setting of the cleaning brush 18 can quickly clean out the seeds blocked in the screening holes, thereby improving the screening efficiency. By setting the limit ring 24, the moving position of the fixing button 22 can be ensured, so that the fixing button 22 will not move out from the inside of the mounting groove 20, nor will it be pushed out of the mounting groove 20 due to the elasticity of the second spring 21. By making the outer diameter size of the fixing block 9 and the inner diameter size of the fixing groove 13 compatible with each other, the fixation between the flow control plate 5 and the discharge chute 3 can be made more stable, and the flow control system can be made more precise.
