Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed screening technology, specifically a vegetable seed screening device. Background Technology
[0002] Vegetable seeds are seeds used to produce vegetables. They are divided into conventional seeds and hybrid seeds. During the storage stage, some seeds may develop mold, insect infestation, or other problems. When growing vegetables, seed screening devices are needed. However, most of the existing seed screening devices cannot screen and remove the seed coat, which can easily affect vegetable cultivation. In addition, most screening devices have low screening efficiency and are inconvenient to use.
[0003] Existing screening devices typically use a water-passing method to remove bad seeds. Good seeds sink to the bottom, while bad seeds float to the surface. However, currently, the seeds are poured into the water in a short time before being mixed, resulting in incomplete contact between the seeds and water. This leads to a significant number of good seeds floating on the surface, severely reducing the screening quality. Therefore, we propose a vegetable seed screening device. Utility Model Content
[0004] In addressing the shortcomings of existing devices where seeds do not fully contact water, resulting in a significant number of good seeds floating and severely reducing screening quality, this invention provides a vegetable seed screening device that ensures sufficient contact between seeds and water, and whose multi-layered filter can effectively improve screening efficiency, thus solving the problems mentioned in the background art.
[0005] The technical solution of this utility model is implemented as follows: A vegetable seed screening device includes a box, with multiple sliding mechanisms installed inside the box. Each sliding mechanism includes a support base connected to the box, and a sliding groove is provided on the top of each of the two support bases. A sliding block is connected in the sliding groove. A U-shaped push rod is slidably installed on one side of the box, with both ends of the push rod extending through into the sliding groove and fastened to one end of the sliding block. An electric telescopic rod is connected between the other side of the push rod and the outer wall of the box. Multiple filter barrels are connected between two sliding blocks. The multiple filter barrels are placed coaxially and their diameter gradually decreases from the outside to the inside. Ear plates are symmetrically connected to the top of the filter barrels, and positioning holes are provided through the ear plates. A positioning rod that mates with the positioning hole is vertically connected to the top of the sliding block. The device also includes a control box, which contains a controller. The electric telescopic rod is connected to the controller.
[0006] Optionally, the push rod is hollow inside, and the end of the groove away from the push rod is connected to the first guide rod, and the other end of the first guide rod passes through the sliding block and extends into the push rod.
[0007] Optionally, a connecting seat is fitted onto the other side of the push rod, and the end of the electric telescopic rod is connected to the connecting seat.
[0008] Optionally, a motor connected to the bottom of the support base is installed between adjacent filter barrels. The motor is connected to the controller, and the output end of the motor is connected to a threaded rod that is rotatably connected to the bottom surface of the housing. A base is threaded onto the threaded rod, and multiple support plates extending to the bottom of the filter barrel are connected to both sides of the base.
[0009] Optionally, a threaded tube is connected to the base, and the threaded rod is connected to the threaded tube.
[0010] Optionally, a sleeve is connected to the support plate, and a second guide rod is installed through the sleeve. The ends of the second guide rod are fastened to the support base and the inner bottom surface of the box, respectively.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Reference Figures 1 to 3 This utility model provides a technical solution: a vegetable seed screening device, including a box 23, with multiple sliding mechanisms installed inside the box 23. Each sliding mechanism includes a support base 3 connected inside the box 23. The top of each of the two support bases 3 is provided with a sliding groove 22, and a sliding block 5 is connected in the sliding groove 22. A push rod 8 with a U-shaped structure is slidably installed on one side of the box 23. Both ends of the push rod 8 extend through into the sliding groove 22 and are fastened to one end of the sliding block 5. An electric telescopic rod 9 is connected between the other side of the push rod 8 and the outer wall of the box 23. The electric telescopic rod 9 drives the push rod 8 to extend and retract, thereby enabling the sliding block 5 to slide stably in the sliding groove 22 and to slide back and forth, which is beneficial for the rapid screening of seeds.
[0021] like Figure 1 , 2 As shown, in order to improve the connection stability between the electric telescopic rod 9 and the push rod 8, a connecting seat 10 is sleeved on the other side of the push rod 8. The end of the electric telescopic rod 9 is connected to the connecting seat 10. The push rod 8 has an internal hollow structure, and a first guide rod 4 is connected to the end of the slide groove 22 away from the push rod 8. The other end of the first guide rod 4 passes through the sliding block 5 and extends into the push rod 8. When the push rod 8 moves back and forth, the sliding block 5 slides on the first guide rod 4, thereby ensuring that the sliding block 5 moves stably.
[0022] Meanwhile, multiple filter barrels 2 are connected between the two sliding blocks 5. The number of filter barrels 2 gradually increases from the inside to the outside. The multiple filter barrels 2 are placed coaxially and their diameter gradually decreases from the outside to the inside. Ear plates 6 are symmetrically connected to the top of the filter barrels 2, and positioning holes 13 are provided through each ear plate 6. Positioning rods 7 that cooperate with the positioning holes 13 are vertically connected to the top of the sliding block 5. During the screening operation, the seeds to be screened are placed in the filter barrels 2 located inside, and water for screening is placed in the box 23. The electric telescopic rod 9 is controlled to push the push rod 8 to move back and forth, so that the seeds and water can be fully mixed. Under the layered filtration of multiple filter barrels 2, the seeds can also be screened quickly, which improves the screening efficiency.
[0023] like Figure 2 , 3 As shown, a motor 17 is connected to the bottom of the support base 3 between adjacent filter barrels 2. The output end of the motor 17 is connected to a threaded rod 16 that is rotatably connected to the bottom surface of the housing 23. A base 15 is threaded onto the threaded rod 16. Multiple support plates 18 extending to the bottom of the filter barrel 2 are connected to both sides of the base 15. Under the control of the motor 17, the base 15 can slide up and down on the threaded rod 16. With the support of the support plates 18 on both sides of the base 15, the bottom of the filter barrel 2 can be supported and moved upward, thereby automatically pushing the seeds and the filter barrel 2 out of the housing 23, saving a lot of manpower.
[0024] In order to improve the stability of the movement of the base 15, a threaded tube 21 is connected to the base 15, and a threaded rod 16 is connected to the threaded tube 21. A sleeve 20 is connected to the support plate 18, and a second guide rod 14 is installed through the sleeve 20. The end of the second guide rod 14 is fastened to the support base 3 and the inner bottom surface of the box 23 respectively. The second guide rod 14 can guide the movement of the support plate 18 and the base 15, further improving the stability of the lifting and lowering of the filter barrel 2.
[0025] In summary, when in use, this vegetable seed screening device also includes a control box 1, which contains a controller. The motor 17 and the electric telescopic rod 9 are connected to the controller. A connecting pipe 12 is connected to one side of the housing 23, and a solenoid valve 11 is connected to the connecting pipe 12. The solenoid valve 11 is connected to the controller, which facilitates the rapid drainage of water inside the housing 23. In order to improve the overall stability of the housing 23, support legs 19 are connected to the four corners of the bottom of the housing 23.
[0026] During the sieving operation, seeds are placed in the inner filter bucket 2, and multiple filter buckets 2 are placed in the housing 23. The ear plate 6 cooperates with the positioning rod 7 to achieve stable placement of the filter bucket 2. After placement, the push rod 8 is pushed by the electric telescopic rod 9 to slide, which can drive the filter bucket 2 to slide horizontally between the support base 3. This allows for full contact between the seeds and water. Plump seeds sink, while shriveled seeds remain on the water surface. At the same time, smaller seeds gradually sink and are filtered in layers by the filter bucket 2. After filtration, the rotation of the motor 17 pushes the base 15 and support plate 18 upward, which lifts the filter bucket 2 upward, making it convenient for workers to remove the filter bucket 2 and saving a lot of manpower. This utility model is not only simple in structure, but also effectively improves the full contact between seeds and water, and can not only achieve layered filtration, but also improve the seed sieving efficiency.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
