Description

Technical Field

[0001] This utility model relates to the field of agricultural planting, and in particular to a device for cultivating Polygonatum seedlings. Background Technology

[0002] Polygonatum is a traditional Chinese medicine. It is a perennial herb belonging to the Polygonatum genus of the Liliaceae family. It is widely used in the field of traditional Chinese medicine and has high medicinal and economic value.

[0003] There are two main methods for cultivating Polygonatum seedlings: rhizome propagation and seed propagation. Rhizome propagation is the primary method used in production, while seed propagation is mostly used for seedling research or large-scale seedling production.

[0004] Chinese Patent Publication No. CN222465530U discloses an agricultural seedling rack, including a support frame; multiple seedling frames, one of which is mounted on the top surface of the support frame; and an extension structure fixed to the support frame. The extension structure includes multiple support blocks mounted on the support frame. The two lower support blocks each have a sliding groove inside. A connecting rod is slidably connected inside the upper sliding groove. A sliding frame is slidably connected inside the lower support block. A limiting sliding frame is fixedly connected to the end of the lower support block. This device, through the support frame and the extension structure in conjunction with the seedling frames, simplifies the structure of the seedling rack. Furthermore, depending on the characteristics of the plant being cultivated, pulling the lowermost seedling frame simultaneously extends the upper seedling frames, resulting in a trapezoidal structure. Compared to existing technologies, this design is more symmetrical and stable, and the telescopic linkage is simple and convenient.

[0005] Although the equipment described in the aforementioned literature can be used for seedling cultivation, it cannot adjust the height of each layer, cannot adapt to seedlings at different growth stages, and cannot regulate sunlight exposure. This may lead to problems such as insufficient light, excessive light, and uneven light distribution, affecting seedling survival rate and growth. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 and Figure 2 As shown, a Solomon's Seal seedling cultivation device includes a seedling rack assembly 1. Several placement components 2 arranged in a linear array are slidably connected to the middle of the seedling rack assembly 1. Adjustment components 3 are slidably connected to both sides of the seedling rack assembly 1. Positioning components 4 are fixedly connected to the upper parts of both sides of the seedling rack assembly 1. The seedling rack assembly 1 includes a base plate 11. Universal wheels 12 are fixedly connected to the four corners of the lower end of the base plate 11. Two upright columns 13 are fixedly connected to the left side of the upper end of the base plate 11. Two upright columns 24 are fixedly connected to the right side of the upper end of the base plate 11. Several slide rails 15 arranged in a linear array are fixedly connected to the ends of the two upright columns 13 that are close to each other. The slide rails 15 are fixedly connected to the adjacent upright column 24. A top plate 16 is fixedly connected to the upper ends of the two upright columns 13 and the two upright columns 24.

[0026] like Figure 3 As shown, the placement component 2 includes a sliding plate 21, which is slidably connected to two slide rails 15 at the same height. A rectangular groove 22 is provided in the middle of the sliding plate 21, and a tray 23 is slidably connected in the rectangular groove 22. Several placement grooves 24 are provided at the upper end of the sliding plate 21, and several round holes 25 are provided on the bottom wall of the inner surface of the several placement grooves 24.

[0027] In this embodiment, the layer height can be adjusted according to the growth of the Polygonatum seedlings. The sliding plate 21 is slid into the slide rail 15 at a suitable height, and then the container containing the Polygonatum seedlings is placed in the placement trough 24. During the breeding process, the tray 23 can be taken out periodically for cleaning.

[0028] Example 2

[0029] Based on Embodiment 1, this embodiment adds adjustment component 3 and positioning component 4. The opening angle of the sunshade can be adjusted according to the growth stage of the Polygonatum seedlings to adapt to the light requirements of the Polygonatum seedlings under different conditions, and the adjusted sunshade can be positioned to prevent the sunshade from shifting.

[0030] like Figure 4As shown, the adjustment assembly 3 includes a gear 31 rotatably connected to the upper side of the column 2 14. One end of the gear 31 has a positioning groove 32. Several gears 33 are slidably connected to the middle of the column 2 14. Each gear 33 is fixedly connected to a connecting rod 34 on its left side. Each connecting rod 34 is rotatably connected to a connecting rod 35 on its lower side. Each connecting rod 35 is fixedly connected to a gear 36 on its lower side. Each gear 36 is slidably connected to the column 2 14. Each gear 36 is fixedly connected to a connecting piece 37 on its right side. The gears 33 and 36 that are close to each other are meshed. The gears 33 and 36 that are close to each other are rotatably connected to a fixing plate 38. The two connecting pieces 37 located at the same height are fixedly connected to a sunshade 39 on their right sides.

[0031] Specifically, both gears 1 31 mesh with a gear 2 33 that is close to each other, and the gear 2 33 that is close to the gear 1 31 is rotatably connected to the column 2 14.

[0032] Furthermore, the two gears 31 are fixedly connected to each other at their close ends with a connecting rod, and the connecting rod is rotatably connected to the upper side of the two columns 14.

[0033] like Figure 5 As shown, the positioning component 4 includes a support 41 fixedly connected to one side of the top plate 16. A rotating plate 42 is rotatably connected to the upper side of the support 41. A rod 43 is rotatably connected to the lower side of the rotating plate 42. A rod 44 is fixedly connected to the end of the rod 43 that is far away from the column 14. One end of the rod 44 passes through the support 41 and is slidably connected to the support 41. A spring 45 is fixedly connected to one end of the rod 43. The spring 45 is sleeved on the outer surface of the rod 44. A gear 46 is fixedly connected to the end of the rod 43 that is close to the column 14.

[0034] Specifically, gear 46 meshes with positioning groove 32.

[0035] The seeds of Polygonatum are sensitive to strong light during germination and seedling stages. Direct sunlight can easily cause leaf burn, growth stagnation, or even death. Seedlings need 60%-70% shading to approximate the diffused light environment under the forest.

[0036] As the seedlings grow, the shading rate can be gradually reduced to 40%-50% to promote photosynthesis and root development.

[0037] During the cultivation of Polygonatum seedlings, the light conditions need to be adjusted according to their growth stage and environment.

[0038] In this embodiment, when it is necessary to adjust the light distribution, the rotating plate 42 is rotated. The rotating plate 42 drives the rod 43 to move. The rod 43 drives the gear 46 to move away from the positioning groove 32, so that the gear 46 separates from the positioning groove 32. Thus, the sunshade 39 can be rotated. When the sunshade 39 rotates, it drives the gear 36 to rotate. The gear 36 drives the gear 2 to rotate, which in turn drives the connecting rod 34 and the connecting rod 2 to rotate. This causes the gear 2 33 and the gear 36 to slide in the vertical direction, rotating the sunshade 39 to a suitable position.

[0039] After releasing the rotating plate 42, under the elastic force of the spring 45, the first rod 43 and the fourth gear 46 are pushed to move towards the positioning groove 32. After the fourth gear 46 engages with the positioning groove 32, the first gear 31 can be positioned so that the first gear 31 cannot rotate, thus fixing the position of several sunshades 39.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
