Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening device technology, specifically a screening device. Background Technology
[0002] Soybean seed screening is a crucial step in ensuring high yield and quality. The main purpose is to remove inferior seeds and retain healthy, plump seeds with high germination rates. Current seed screening methods typically involve wind selection followed by further screening. Wind selection first uses air force to blow away light impurities (such as shriveled seeds and weed seeds), retaining heavy and plump seeds. Then, the seeds are screened through a fixed-gap sieve based on their size, shape, and other characteristics to remove those that do not meet the requirements.
[0003] The existing method for screening seeds involves a ramp with screening openings of different sizes. Each screening opening is fitted with a sieve, and the sieve spacing varies at different locations to facilitate the screening of soybean seeds of different sizes. The seeds are then stored in storage boxes located at fixed positions at the bottom of the sieves. However, most of the existing storage boxes are placed separately, and the weight of the boxes and the piled-up seeds makes it difficult to move them manually after screening.
[0004] Therefore, it is necessary to provide a new screening device to solve the above-mentioned technical problems. Utility Model Content

The seeds can be air-selected by the set fan in conjunction with the collection trough.
[0011] Preferably, the top of both sets of movable frames is fixedly connected to a screening slope, and screening ports of different sizes are opened sequentially at the center of the two sets of screening slopes. The inner walls of the multiple sets of screening ports are fixedly connected to screens with different gaps between them. The screens can be used to screen seeds of different sizes separately.
[0012] Preferably, both sets of movable frames are fixedly connected to limit rings inside, and multiple sets of limit rings are provided. Each set of limit rings is slidably connected to a storage box inside. The top opening of each set of storage boxes is connected to the bottom of the screening port.

[0016] Compared with related technologies, the screening device provided by this utility model has the following beneficial effects:
[0017] This utility model provides a screening device;
[0018] 1. This utility model can transport the sorted seeds using a movable frame. When it is necessary to move and transport the sorted seeds, the movable frame can be pulled outward from the connecting groove by manually holding the push rod. This causes the sliding grooves on both sides of the movable frame to slide through the sliders. The rotation of the movable wheels drives the movable frame to move, pulling it out of the connecting groove. By pushing the push rod, the movable frame and the seeds stored inside the internal storage box can be moved, thereby realizing the transportation of the sorted seeds.
[0019] 2. This utility model can screen seeds using a set of sieves. When seed screening is required, seeds are transported to a platform via a rotating conveyor belt on a conveyor frame. The drop between the platform and the conveyor belt causes the seeds to fall. Simultaneously, the blower is activated by operating the external controller to blow air onto the falling seeds, blowing impurities in the seeds to a baffle plate. The seeds then fall into a collection box that is slidably connected inside the collection trough for collection. Seeds that fall onto the platform are separated onto movable frames on both sides via a separation ramp. The seeds slide along the screening ramp and fall into a storage box through multiple sets of sieves with different gaps installed at the screening ports, thereby achieving the screening of seeds of different sizes.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0027] Please see Figures 1 to 4 The present invention provides a screening device, the screening device comprising:
[0028] Platform 1, with surrounding plates 2 fixedly connected to both sides of platform 1;
[0029] The movable frame 10 has a connecting groove 9 on one side of the surrounding plate 2. There are two sets of connecting grooves 9, and the movable frame 10 is slidably connected inside the two sets of connecting grooves 9. The two sets of movable frames 10 have sliding grooves 18 on both sides. The inner walls of the two sets of connecting grooves 9 are fixedly connected to sliders 19. The two sets of movable frames 10 are slidably connected to sliders 19 through sliding grooves 18. The two sets of movable frames 10 have push rods 11 fixedly connected to one side.
[0030] It should be noted that when the sorted seeds need to be moved and transported, the moving frame 10 can be pulled outward from the connecting groove 9 by manually holding the push rod 11. This causes the sliding grooves 18 on both sides of the moving frame 10 to slide through the slider 19, and the moving wheels 17 to rotate, thus moving the moving frame 10 out of the connecting groove 9. By pushing the push rod 11, the moving frame 10 and the seeds stored inside the internal storage box 15 can be moved, thereby realizing the transportation of the sorted seeds. When the seeds need to be sorted, they can be transferred to the platform 1 via the rotating conveyor belt 6 on the transfer frame 4. The seeds fall due to the drop between platform 1 and conveyor belt 6. As they fall, the fan 21 is activated by the controller on the outside. The fan 21 blows air onto the falling seeds, blowing impurities in the seeds to the baffle plate 22. The seeds fall through the baffle plate 22 and are collected in the collection box 24 that is slidably connected inside the collection tank 23. The seeds that fall onto platform 1 are separated by the separation ramp 8 and placed on the moving frames 10 on both sides. The seeds slide through the screening ramp 12 and fall into the storage box 15 through the screens 26 with different gaps installed in multiple sets of screening ports 13. This achieves the screening of seeds of different sizes.
[0031] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 A push rod motor 20 is fixedly connected to the top of the platform 1. A hinge 3 is fixedly connected to the top of the push rod motor 20. A transmission frame 4 is fixedly connected to the top of the hinge 3. A rotary motor 5 is fixedly connected to one side of the transmission frame 4. A through hole is opened on one side of the transmission frame 4. The output end of the rotary motor 5 passes through the through hole to the inside of the transmission frame 4. A transmission belt 6 is sleeved on the output end. Seeds can be transferred to the platform 1 for screening through the transmission belt 6.
[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 4A separation ramp 8 is fixedly connected to the top of the platform 1. A fan 21 is fixedly connected to one side of the separation ramp 8. A collection trough 23 is provided on the side of the separation ramp 8 near the push rod motor 20. A baffle plate 22 is fixedly connected to the side of the collection trough 23 near the push rod motor 20. The seeds can be air-selected by the fan 21 in conjunction with the collection trough 23.
[0033] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 Both sets of movable frames 10 are fixedly connected to the top of a screening slope 12. The center of the two sets of screening slopes 12 is provided with screening ports 13 of different sizes. The inner walls of the multiple sets of screening ports 13 are fixedly connected with screens 26. The gaps between the screens 26 are different. Seeds of different sizes can be screened separately through the screens 26.
[0034] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 Both sets of movable frames 10 are fixedly connected to the inside of the limit rings 14. There are multiple sets of limit rings 14. The storage boxes 15 are slidably connected inside the multiple sets of limit rings 14. The top opening of the multiple sets of storage boxes 15 is connected to the bottom of the screening port 13. The outside of the multiple sets of storage boxes 15 is fixedly connected to the handles 16. The position of the storage boxes 15 can be placed and fixed by the limit rings 14.
[0035] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 One end of the collection trough 23 is opened on one side of the platform 1. A collection box 24 is slidably connected inside the collection trough 23. A pull rod 25 is fixedly connected to one side of the collection box 24. Impurities in the seeds can be collected through the collection box 24.
[0036] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 Both sets of movable frames 10 are fixedly connected to the bottom of each set of movable frames 10. Multiple sets of movable frames 17 are provided, and the movable frames 10 can be moved by the movable frames 17.
[0037] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 One side of the rotary motor 5, push rod motor 20 and fan 21 is fixedly connected with wires 7, through which power and control signals can be transmitted to each electronic component.
[0038] The working principle of the screening device provided by this utility model is as follows:
[0039] In use, when it is necessary to move and transport the sorted seeds, the push rod 11 can be manually held to pull the moving frame 10 outward from the connecting groove 9. This causes the sliding grooves 18 on both sides of the moving frame 10 to slide through the slider 19, and the rotation of the moving wheels 17 drives the moving frame 10 to move, pulling it out of the connecting groove 9. By pushing the push rod 11, the moving frame 10 and the seeds stored inside the internal storage box 15 can be moved, thereby realizing the transportation of the sorted seeds. When it is necessary to sort the seeds, the seeds can be transferred to the platform 1 via the rotating conveyor belt 6 on the transfer frame 4. The seeds fall due to the drop between platform 1 and conveyor belt 6. Simultaneously, the blower 21 is activated by the controller on the outside, blowing air onto the falling seeds and dispersing impurities to the baffle plate 22. The seeds then fall through the baffle plate 22 into the collection box 24, which is slidably connected inside the collection trough 23. The seeds that fall onto platform 1 are separated onto the movable frames 10 on both sides by the separation ramp 8. The seeds slide through the screening ramp 12 and fall into the storage box 15 through the screens 26 with different gaps installed in multiple sets of screening ports 13, thereby achieving the screening of seeds of different sizes.
