Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a seed screening device for Chinese cabbage. Background Technology

[0002] Bok choy is a common variety of Chinese cabbage, belonging to the Brassicaceae family and the Brassica genus. Its seeds are very small, spherical, and typically reddish-brown or dark brown. It is widely used in agricultural production, commercial cultivation, and home gardening. A bok choy seed screening device can effectively remove inferior seeds, significantly improving germination rates and ensuring uniform sowing, thus guaranteeing consistent seedling emergence.

[0003] However, existing seed screening devices for Chinese cabbage cannot quickly separate the seeds, resulting in a significant delay in the process. Furthermore, if the Chinese cabbage seeds are damp, they tend to stick together, and existing screening devices cannot effectively separate these sticky seeds, leading to the screening of defective seeds as well, thus affecting the screening quality.

[0004] Therefore, this application provides a seed screening device for Chinese spinach to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seed screening device for Chinese cabbage. This device can quickly screen seeds and can also screen moist and sticky seeds.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A seed screening device for Chinese spinach includes a screening box and a connecting frame. The screening box has three discharge ports at its front end, sliding grooves on both sides of its inner wall, and a hole in the middle of its rear end. A spoiled seed box is fixedly mounted on the upper surface of the screening box, and an interception box is fixedly connected to its front end. A sliding box is slidably mounted on the bottom surface of the interception box. A feeding box is fixedly mounted on the upper surface of the interception box. Soft brush rollers are rotatably mounted on both sides of the inner wall of the feeding box via bearings. An interception net is fixedly connected to the front end of both the feeding box and the interception box. Both the material box and the interception box are fixedly connected to a blower at their rear ends. An interception groove is opened on the lower end face of one side of the outer wall of the material box. Slider blocks are fixedly installed on both sides of the outer wall of the connecting frame. A bottom box is fixedly installed on both sides of the inner wall of the connecting frame at the lower end. Two screening boxes are fixedly installed on both sides of the inner wall of the connecting frame at the upper end of the bottom box. An inner discharge port is opened in the middle of the front end of the two screening boxes and the bottom box. A rotating seat is fixedly installed in the middle of the rear end of the connecting frame, and a connecting rod is rotatably installed in the middle of the rotating seat. A turntable is rotatably installed on one side of the outer wall of the connecting rod near the rear end via a rotating shaft.

[0007] Furthermore, a first motor is fixedly installed in the middle of the other side of the outer wall of the feeding box, and the output end of the first motor passes through the other side of the outer wall of the feeding box and is fixedly connected to one end of the outer wall of the soft roller.

[0008] Furthermore, a partition is slidably disposed inside the interception groove.

[0009] Furthermore, a second motor is fixedly installed at the rear end of the screening box on one side of the hole, and the output end of the second motor is fixedly connected to the middle of one side of the outer wall of the turntable.

Detailed Implementation

[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] Reference Figure 1 — Figure 6 This utility model provides an embodiment of a seed screening device for Chinese spinach, comprising a screening box 1 and a connecting frame 22. The screening box 1 has three outlet ports 2 at its front end, and sliding grooves 17 on both sides of its inner wall. A hole 11 is located in the middle of the rear end of the screening box 1. A spoiled seed box 3 is fixedly mounted on the upper surface of the screening box 1. An interception box 16 is fixedly connected to the front end of the spoiled seed box 3. A sliding box 5 is slidably mounted on the bottom surface of the interception box 16. A feeding box 6 is fixedly mounted on the upper surface of the interception box 16. Soft brush rollers 9 are rotatably mounted on both sides of the inner wall of the feeding box 6 via bearings. An interception net 4 is fixedly connected to the front ends of both the feeding box 6 and the interception box 16. Both the feeding box 6 and the intercepting box 16 are fixedly connected to the rear end of the blower 7. The lower end face of one side of the outer wall of the feeding box 6 is provided with an intercepting groove 15. Both sides of the outer wall of the connecting frame 22 are fixedly provided with sliders 18. Both sides of the inner wall of the connecting frame 22 are fixedly provided with a bottom box 20. Both sides of the inner wall of the connecting frame 22 are fixedly provided with two screening boxes 19 located above the bottom box 20. Both screening boxes 19 and the middle of the front end of the bottom box 20 are provided with an inner discharge port 21. A rotating seat is fixedly provided in the middle of the rear end of the connecting frame 22, and a connecting rod 14 is rotatably provided in the middle of the rotating seat. A turntable 13 is rotatably provided on one side of the outer wall of the connecting rod 14 near the rear end via a rotating shaft.

[0019] Specifically, when using this device, first check if the seeds are damp and sticky. If they are damp and sticky, slide the partition 10 into the interception trough 15, and then pour the seeds into the feeding box 6. Then, start the first motor 8 via the control panel to drive the soft roller 9 to rotate, and simultaneously start the blower 7 at the rear of the feeding box 6 via the control panel. The soft roller 9 continuously rotates the seeds, and the blower 7 continuously generates airflow to rotate the seeds, thereby removing moisture from the outer surface of the seeds and preventing sticking. Once the seeds are no longer sticky, start the blower 7 at the rear of the bad seed box 3 via the control panel, and then pull the partition 10 out of the interception trough 15, or control the seed flow rate by adjusting the position of the partition 10 inside the interception trough 15. Because bad seeds and seeds with underdeveloped kernels are lighter than normal seeds, the airflow generated by the blower 7 blows bad seeds and underdeveloped kernels into the interception box 16, where they fall into the sliding box 5. The seeds will then fall into the screening mesh box 19 in the middle of the connecting frame 22 for screening. The second motor 12 is activated via the control panel, causing the turntable 13 to rotate. This, in turn, moves the rear end of the connecting rod 14 in a circular motion, thereby moving the connecting frame 22 back and forth to sieve the seeds. The sieved seeds will be discharged through multiple internal discharge ports 21. Workers should connect the multiple external discharge ports 21 to the seed storage bags in advance. The seeds sieved from the top layer are perfect, plump seeds; the seeds sieved from the second layer are good seeds; and the seeds discharged from the bottom box 20 are smaller, inferior seeds.

[0020] Reference Figure 1 — Figure 3 A feeding box 6 is fixedly installed on the upper end face of the interception box 16. Soft brush rollers 9 are rotatably installed on both sides of the inner wall of the feeding box 6 via bearings. An interception net 4 is fixedly connected to the front end of both the feeding box 6 and the interception box 16. A blower 7 is fixedly connected to the rear end of both the feeding box 6 and the interception box 16. An interception groove 15 is opened on the lower end face of one side of the outer wall of the feeding box 6. A first motor 8 is fixedly installed in the middle of the other side of the outer wall of the feeding box 6. The output end of the first motor 8 passes through the other side of the outer wall of the feeding box 6 and is fixedly connected to one end of the outer wall of the soft brush roller 9. A partition 10 is slidably installed inside the interception groove 15.

[0021] Specifically, heavy assets can be placed in the feeding box 6. The first motor 8 drives the soft-bristled roller 9 to rotate, causing the seeds to tumble. Because the soft-bristled roller 9 has soft nylon bristles, it can effectively prevent damage to the seeds. The intercepting net 4 can prevent seeds from leaking out and also allow air containing moisture to escape. Sliding the partition 10 into the intercepting groove 15 can limit the downward slide of seeds, and adjusting its position can limit the flow rate of seeds.

[0022] Reference Figure 1 , Figure 2 , Figure 4Both the feeding box 6 and the intercepting box 16 are fixedly connected to the rear end of the blower 7. An intercepting groove 15 is opened on the lower end face of one side of the outer wall of the feeding box 6. A bad seed box 3 is fixedly installed on the upper end face of the screening box 1. An intercepting box 16 is fixedly connected to the front end of the bad seed box 3. A sliding box 5 is slidably installed on the bottom surface of the intercepting box 16. A control panel is fixedly connected to one side of the outer wall of the bad seed box 3.

[0023] Specifically, the blower 7 at the rear of the bad seed box 3 blows bad seeds and underdeveloped seeds into the sliding box 5 inside the interception box 16. The interception net 4 at the front of the interception box 16 prevents bad seeds and underdeveloped seeds from splashing around. The sliding box 5 quickly collects bad seeds and underdeveloped seeds. The device can be controlled via a control panel.

[0024] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 The connecting frame 22 has sliders 18 fixedly installed on both sides of its outer wall. A base box 20 is fixedly installed on the lower ends of both sides of the inner wall of the connecting frame 22. Two screening boxes 19 are fixedly installed on the upper ends of the base boxes 20 on both sides of the inner wall of the connecting frame 22. An inner discharge port 21 is opened at the center of the front end of both screening boxes 19 and the base box 20. A rotating seat is fixedly installed at the center of the rear end of the connecting frame 22, and a connecting rod 14 is rotatably mounted in the middle of the rotating seat. A turntable 13 is rotatably mounted on one side of the outer wall of the connecting rod 14 near its rear end via a rotating shaft. The screening box 1 has three discharge ports 2 at the front end. The inner walls of the screening box 1 are provided with sliding grooves 17 on both sides. The rear end of the screening box 1 has a hole 11 in the middle. The rear end of the screening box 1 is fixedly installed on one side of the hole 11. The output end of the second motor 12 is fixedly connected to the middle of one side of the outer wall of the turntable 13. Two sliders 18 are respectively slidably installed inside the two sliding grooves 17. The connecting frame 22 is slidably installed inside the screening box 1. The three inner discharge ports 21 are respectively slidably installed inside the three discharge ports 2.

[0025] Specifically, the two sliders 18 slide inside the two grooves 17, which restricts the movement direction of the connecting frame 22, allowing it to move only in a straight line back and forth. The second motor 12 drives the turntable 13 to rotate, which in turn drives the connecting rod 14 to move the connecting frame 22 back and forth, thus screening the seeds through the two screening boxes 19 and the bottom box 20. The screened seeds are discharged through multiple internal discharge ports 21 to prevent accumulation inside.

[0026] Working principle: When using this device, first connect the three seed storage bags to the three outflow ports 2 respectively. Then check if the seeds are damp and sticky. If they are, insert the partition 10 into the interception groove 15. Then start the blower 7 at the rear of the feeding box 6 and the first motor 8 to remove the moisture from the outer surface of the seeds. Then turn on the second motor 12 and the blower 7 at the rear of the bad seed box 3, and pull out the partition 10. The airflow generated by the blower 7 blows the bad seeds and unfilled seeds into the sliding box 5. The second motor 12 drives the connecting frame 22 to move back and forth, causing the seeds to shake and be screened.
