Abstract
Description
Technical Field
[0001] This utility model belongs to the field of crop breeding technology, and specifically relates to a crop breeding shading device. Background Technology
[0002] In the process of crop breeding, proper shading can be more conducive to the germination of crop seeds.
[0003] Currently, Chinese utility model patent CN218417494U discloses a shading device for crop breeding. However, while existing shading devices can effectively block light during the crop breeding process, the shading plate can only be adjusted between full shading and no shading. It cannot adjust the light intensity when no shading is applied according to the seed germination process, thus limiting its practicality. Furthermore, because existing shading devices cannot adjust the height of the shading plate, it cannot be raised after seed germination to expand the space above the seedlings, thus hindering seedling growth and impacting subsequent development. Utility Model Content
[0004] The purpose of this invention is to provide a crop breeding shading device, which has the advantages of being able to adjust the light intensity when shading and not shading, and can also be raised to expand the seed growth space.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a crop breeding shading device, including a fixed frame, a shading plate bolted inside the fixed frame, a first through hole opened inside the shading plate, a sliding plate slidably connected to the fixed frame at the top of the shading plate, a second through hole opened inside the sliding plate to cooperate with the first through hole, an L-shaped slider welded to one end of the sliding plate, and a threaded rod rotatably connected to the L-shaped slider through a threaded connection at the end of the fixed frame near the L-shaped slider.
[0006] By employing the above technical solution, the sliding plate can be moved within the fixed frame, allowing adjustment of the area where the second and first through holes overlap. This allows for adjustment of the light intensity passing through the second and first through holes as the hole size changes during overlap, meeting the breeding needs of different crops and improving practicality. Furthermore, by raising the fixed frame, the support legs slide within the fixed cylinder, and the spring force drives the insertion rod to extend from the support legs, limiting and fixing the height of the fixed frame. This allows for adjustment of the seed growth space, preventing interference with seedling growth after breeding.
[0007] The present invention is further configured such that: a support leg is bolted to the bottom of the fixed frame, a fixed cylinder is slidably sleeved to the bottom of the support leg, an insertion hole is opened on one side of the fixed cylinder, a spring is bolted to the inside of the support leg, and an insertion rod that is slidably inserted into the insertion hole is bolted to the side of the spring near the insertion hole.
[0008] By adopting the above technical solution, the fixed frame can be raised to adjust the growth space of crop seeds, thereby avoiding the impact on seedling growth after breeding.
[0009] The present invention is further configured such that: both sides of the sliding plate are slidably connected to ball bearings that are rotatably connected to the fixed frame.
[0010] By adopting the above technical solution, the friction of the sliding plate sliding inside the fixed frame is reduced, and the sliding stability is improved.
[0011] The present invention is further configured such that a waterproof lens bonded to the sliding plate is disposed inside the second through hole.
[0012] By adopting the above technical solution, dust or sewage can be prevented from falling into the bottom of the fixed frame and affecting crop seeds when the second through hole and the first through hole are connected.
[0013] The present invention is further configured such that: the end of the threaded rod away from the L-shaped slider is bolted with a handle that is rotatably connected to the fixed frame.
[0014] By using the above technical solution, the position of the sliding plate can be adjusted by rotating the screw rod through the handle.
[0015] The present invention is further provided that: an anti-slip pad is adhered to the bottom of the fixed cylinder.
[0016] By adopting the above technical solution, the friction at the bottom is increased, thereby improving the stability of placement.
[0017] In summary, this utility model has the following beneficial effects:
[0018] 1. By sliding the sliding plate inside the fixed frame, the area where the second through hole overlaps with the first through hole can be adjusted. This allows for adjustment of the intensity of light passing through the second and first through holes as the hole size changes during overlap, meeting the breeding needs of different crops and improving practicality.
[0019] 2. By raising the fixed frame, the support legs slide inside the fixed cylinder, and the spring force drives the insertion rod to extend from inside the support legs to limit and fix the height of the fixed frame. This allows for adjustment of the growth space for crop seeds, preventing interference with seedling growth after breeding. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Example 1:
[0027] refer to Figure 1 , Figure 2 , Figure 3 A crop breeding shading device includes a fixed frame 1, a shading plate 2 bolted inside the fixed frame 1, a first through hole 3 inside the shading plate 2, a sliding plate 4 slidably connected to the fixed frame 1 at the top of the shading plate 2, a second through hole 5 inside the sliding plate 4 that cooperates with the first through hole 3, an L-shaped slider 15 welded to one end of the sliding plate 4, and a threaded rod 16 rotatably connected to the L-shaped slider 15 through a threaded connection at the end of the fixed frame 1 near the L-shaped slider 15. By sliding the sliding plate 4 inside the fixed frame 1, the area where the second through hole 5 overlaps with the first through hole 3 can be adjusted. Thus, when the size of the holes changes during overlap, the intensity of light passing through the second through hole 5 and the first through hole 3 can be adjusted to meet the breeding needs of different crops and improve practicality.
[0028] refer to Figure 3 Both sides of the sliding plate 4 are slidably connected to ball bearings 11 that are rotatably connected to the fixed frame 1. This reduces the friction of the sliding plate 4 sliding inside the fixed frame 1 and improves sliding stability.
[0029] refer to Figure 2 , Figure 3A waterproof lens 12, bonded to the sliding plate 4, is installed inside the second through hole 5. This prevents dust or sewage from falling into the bottom of the fixed frame 1 and affecting the crop seeds when the second through hole 5 and the first through hole 3 are connected.
[0030] refer to Figure 1 , Figure 2 The end of the threaded rod 16 away from the L-shaped slider 15 is bolted with a handle 14 that is rotatably connected to the fixed frame 1. By rotating the handle 14, the threaded rod 16 can be rotated, thereby allowing the position of the sliding plate 4 to be adjusted.
[0031] Brief description of the operation: By rotating the threaded rod 16, which engages with the fixed frame 1, the threaded rod 16 drives the sliding plate 4 to slide inside the fixed frame 1 via the waterproof lens 12. Then, by controlling the overlap between the second through hole 5 inside the sliding plate 4 and the first through hole 3 inside the light-shielding plate 2, light can pass through the second through hole 5 and the first through hole 3 to irradiate the crop seeds at the bottom of the fixed frame 1. By sliding the sliding plate 4, the overlapping area of the second through hole 5 and the first through hole 3 can be adjusted, changing the size of the holes and thus adjusting the intensity of light irradiation through the second through hole 5 and the first through hole 3. Simultaneously, by moving the sliding plate 4, the second through hole 5 and the first through hole 3 are staggered, ensuring that light can only pass through the second through hole 5 and is blocked by the light-shielding plate 2, thereby shading the crop seeds.
[0032] Example 2:
[0033] refer to Figure 1 , Figure 3 , Figure 4 A crop breeding device includes a fixed frame 1 with a support leg 6 bolted to its bottom. A fixed cylinder 7 is slidably fitted onto the bottom of the support leg 6. An insertion hole 8 is opened on one side of the fixed cylinder 7. A spring 10 is bolted inside the support leg 6, and an insertion rod 9, which slides into the insertion hole 8, is bolted to the side of the spring 10 closest to the insertion hole 8. By raising the fixed frame 1, the support leg 6 slides inside the fixed cylinder 7, and the spring force of the spring 10 drives the insertion rod 9 to extend out of the support leg 6, thus limiting and fixing the height of the fixed frame 1. This allows for adjustment of the growth space for crop seeds, preventing interference with seedling growth after breeding.
[0034] refer to Figure 1 , Figure 3 The bottom of the fixing cylinder 7 is glued with an anti-slip pad 13. This increases the friction at the bottom and improves the stability of the placement.
[0035] Brief description of usage: By pressing the insertion rod 9, the spring 10 is compressed, causing it to overcome the elastic force of the spring 10 and slide into the support leg 6 from inside the insertion hole 8. Then, by raising the fixing frame 1, the support leg 6 slides inside the fixing cylinder 7. Afterwards, the rebound force of the spring 10 is used to drive the insertion rod 9 to extend out of the support leg 6 again, so that the insertion rod 9 is locked in the insertion hole 8, thus limiting and fixing the height of the fixing frame 1.
[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
