[0028] First Embodiment

[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a corn breeding cultivation rack provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure; Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of part B is shown. A corn breeding cultivation rack includes: a base plate 1;

[0030] Support plate 2, which is fixedly installed on the top of the base plate 1, and a through groove 22 is provided on the side of the support plate 2;

[0031] The take-up and release assembly 3 is disposed on the side of the support plate 2. The take-up and release assembly 3 includes a rotating shaft 31. One end of the rotating shaft 31 is rotatably connected to one side of the inner side of the through groove 22. Both ends of the outer side of the rotating shaft 31 are fixedly installed with take-up wheels 32. The other end of the rotating shaft 31 is fixedly installed with a worm gear 34. The bottom of the worm gear 34 is engaged with a worm 35. One end of the worm 35 is fixedly installed with a crank handle 36. The other end of the worm 35 is rotatably connected to a mounting frame 33. The mounting frame 33 is fixedly installed on the end face of the support plate 2.

[0032] The shielding assembly 5 is respectively disposed on the top of both sides of the support plate 2. The shielding assembly 5 includes a rotating seat 51, which is fixedly installed on the top of the side of the support plate 2. The shielding plate 52 is rotatably connected inside the rotating seat 51. A pull rope 6 is fixedly installed on one side of the shielding plate 52, and one end of the pull rope 6 is fixedly installed on the outer side of the winding wheel 32.

[0033] Both ends of the top of the support plate 2 are fixedly installed with support frames 4, and the top of the inner side of the support frame 4 is rotatably connected with two guide rods 41.

[0034] The bottom of the pull rope 6 is attached to the top of the guide rod 41.

[0035] Rollers 11 are fixedly installed around the bottom of the base plate 1.

[0036] Multiple planting frames 21 are provided on both sides of the support plate 2.

[0037] The worm gear 34 and worm 35 mesh and drive the system, which has a self-locking function. When the cover plate 52 is opened or retracted, the worm 35 will not easily rotate, ensuring the stability of the cover plate 52 position and preventing the cover plate 52 from affecting the shading effect on the corn or causing the cover plate 52 to retract accidentally during use. In addition, multiple planting frames 21 are set on both sides of the support plate 2, which makes it convenient for researchers to conduct breeding experiments on multiple different corn varieties at the same time, improving the space utilization and experimental efficiency of the cultivation rack. Rollers 11 are installed around the bottom of the base plate 1, making the entire cultivation rack easy to move. Researchers can flexibly adjust the position of the cultivation rack according to actual needs, providing more convenience for corn breeding experiments.

[0038] The working principle of the corn breeding cultivation rack provided by this utility model is as follows:

[0039] When in use, if the cover plate 52 needs to be opened to cover the corn, the user can turn the crank handle 36, which will drive the worm 35 to rotate. Since the worm 35 and the worm wheel 34 mesh with each other, the worm 35 will drive the worm wheel 34 to rotate. The worm wheel 34 is fixedly installed on the rotating shaft 31, so when the worm wheel 34 rotates, it will drive the winding wheel 32 to rotate through the rotating shaft 31. During the rotation of the winding wheel 32, the pull rope 6 wound on the outer side is released. One end of the pull rope 6 is fixed to the outer side of the winding wheel 32, and the other end is connected to the baffle plate 52. At this time, one end of the baffle plate 52 will rotate and open on the inner side of the rotating seat 51 with the rotating seat 51 as the axis. The baffle plate 52 gradually unfolds and plays the role of covering the corn. During this process, the bottom of the pull rope 6 overlaps the top of the guide rod 41. The guide rod 41 can guide the pull rope 6, making the pull rope 6 more stable during the movement, avoiding the pull rope 6 from deviating, and ensuring that the baffle plate 52 can be opened smoothly.

[0040] When the shielding is not needed, the crank handle 36 can be reversed. The crank handle 36 drives the worm gear 35 to rotate in the opposite direction, which in turn drives the worm wheel 34 to rotate in the opposite direction. The worm wheel 34 drives the take-up wheel 32 to rotate in the opposite direction via the rotating shaft 31, causing the pull rope 6 to rewind around the outer side of the take-up wheel 32. During the winding process, one end of the pull rope 6 pulls the shielding plate 52, causing the shielding plate 52 to rotate around the rotating seat 51 until it is parallel to the support plate 2, thus serving to store the shielding plate 52. Similarly, the guide rod 41 guides the pull rope 6 during its retraction, ensuring that the pull rope 6 can be smoothly wound onto the take-up wheel 32 and that the shielding plate 52 can be smoothly stored.

[0041] Compared with related technologies, the corn breeding cultivation rack provided by this utility model has the following advantages:

[0042] Beneficial effects:

[0043] The structure, consisting of a base plate 1, a support plate 2, a retraction assembly 3, a shielding assembly 5, and a pull rope 6, works together to open and close the shielding plate 52 simply by turning the crank 36. Compared to the cumbersome operation process of existing cultivation rack rain shield retraction methods, this method saves a lot of time and effort, improves work efficiency, and better meets the needs of researchers to conduct corn breeding experiments efficiently.
