Description

Technical Field

[0001] The utility model belongs to the technical field of planting equipment, and particularly relates to a seedling-raising rack. Background Technique

[0002] Seedling raising means cultivating seedlings, which refers to cultivating seedlings in a nursery, hotbed or greenhouse for transplantation into the land for planting, such as the seedling raising of tea trees and flowers. Through centralized seedling raising, it is convenient to manage in the early stage, especially pest control; after the seedlings are transplanted and planted, there is no slow seedling stage, and the plants grow neatly; the nutrient formula of the substrate used for seedling raising is reasonable, the cultivated seedlings are strong, the roots are developed, the growth is fast, the flower bud differentiation is good, the yield is increased and the market can be entered earlier; the special substrate for seedling raising is free of germs and toxins, reducing the occurrence of soil-borne diseases; the plastic tray seedling raising is convenient for transportation, saving labor, time and effort.

[0003] At present, in the process of seedling raising, in order to save space, seedlings are generally cultivated on a planting rack, and the shelf boards of the seedling-raising rack are set to be pull-out type, which is convenient for hierarchical management of seedling varieties. For example, in the prior art, a seedling-raising rack for flower planting disclosed in the utility model with the application number 202121484724.x includes a support frame and universal wheels. The bottom end of the support frame is fixedly connected with universal wheels. The support frames are connected by sliding rods, and sliders are sleeved on the surfaces of the sliding rods. By setting the sliders and the placing plate, by pulling the placing plate, the placing plate can be conveniently pulled out of the inside of the support frame, facilitating the maintenance and arrangement of flower seedlings layer by layer, avoiding the need to remove the flower seedlings from the surface of the placing plate when the flower seedlings need to be maintained and arranged, and effectively improving the efficiency of flower seedling maintenance and arrangement.

[0004] However, in the actual application process, the applicant found that, for example, the seedling-raising rack provided by the above technical solution, although using the seedling-raising rack to save space and facilitating hierarchical management of seedlings through the pull-out design of the placing plate, when raising seedlings, the placing plate must carry the soil or nutrient solution for raising seedlings. When the placing plate is pulled out of the seedling-raising rack, most of the area of the placing plate is in a suspended state. It is very difficult to keep the pulled-out placing plate stable only by the cooperation of the slider and the sliding rod. There is a problem that the seedlings fall due to the overload of the suspended part of the placing plate and the resulting tipping. Therefore, we propose a seedling-raising rack for flower planting to solve the above problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] This embodiment provides a seedling-raising rack, and its structural schematic diagram is as Figures 1-5 shown, including four vertical and interconnected vertical arms 1. Specifically, a connecting plate 4 is connected between the bottoms of two adjacent vertical arms 1, and a connecting rod 5 is connected between the tops of two adjacent vertical arms 1 for connecting and fixing the four vertical arms 1 to form a seedling-raising rack body. A roller 6 is installed at the bottom end of each vertical arm 1 to facilitate the movement of the seedling-raising rack body.

[0029] As a preferred technical solution in this embodiment, multiple support plates 2 are horizontally arranged between the four vertical arms 1. A support block 3 located at the bottom of the support plate 2 is provided on the side of the vertical arm 1 facing the support plate 2. The support block 3 is used to support and limit the support plate 2. By stacking multiple support plates 2 in the rack body composed of the four vertical arms 1, the occupied space is reduced, and the support of the support plate 2 by the support blocks 3 on the four vertical arms 1 is utilized. By pulling the support plate 2, the support plate 2 and the seedling-raising box 8 can be pulled out together from the inside of the rack body composed of the four vertical arms 1, which is convenient for the planting and cultivation of seedlings.

[0030] In this embodiment, a seedling-raising box 8 is provided on the upper surface of the support plate 2 for raising seedlings. A rear baffle 9 is provided on the side of the vertical arm 1 close to the first pulley 13 for limiting the rear end of the seedling-raising box 8. A pull ring 10 is provided on the side of the support plate 2 away from the first pulley 13 for pulling the support plate 2. A third pulley 17 is embedded on the upper surface of the support block 3. The third pulley 17 is arranged along the length direction of the support plate 2, and the lower surface of the support plate 2 is in contact with the third pulley 17. The rolling of the third pulley 17 makes the pulling of the support plate 2 smoother.

[0031] As a preferred technical solution in this embodiment, guide plates 7 are provided at both ends of each pallet 2. The guide plates 7 are fixed on two adjacent vertical arms 1, specifically by bolt connection, which is convenient for disassembly and assembly. A first limiting guide groove 11 and a second limiting guide groove 12 are formed in the guide plate 7 along the length direction. A first pulley 13 embedded in the first limiting guide groove 11 is provided on the end face of the pallet 2. An auxiliary arm 14 extending vertically downward is provided at the end of the pallet 2. A second pulley 15 embedded in the second limiting guide groove 12 is provided at the bottom of the auxiliary arm 14. An inclined reinforcing arm 16 is provided between the bottom of the auxiliary arm 14 and the lower surface of the pallet 2. During the pulling process of the pallet 2, the first pulley 13 at the end of the pallet 2 rolls along the first limiting guide groove 11, and the second pulley 15 on the auxiliary arm 14 at the bottom of the pallet 2 rolls along the second limiting guide groove 12. In addition, with the cooperation of the inclined reinforcing arm 16 connecting the auxiliary arm 14 and the bottom of the pallet 2, the pallet 2 can be supported auxiliary, improving the stability of the pallet 2, making the pulled-out pallet 2 maintain a stable state as much as possible, and avoiding the problem that the seedling-raising box 8 is too heavy when the pallet 2 is pulled out, resulting in the pallet 2 tipping downward and the seedling-raising box 8 falling. Moreover, the first pulley 13 and the second pulley 15 are respectively in sliding fit with the first limiting guide groove 11 and the second limiting guide groove 12, which can limit the pallet 2 during the pulling process and avoid the problem that the pulling distance of the pallet 2 is too large and it falls out between the four vertical arms 1.

[0032] Further, in this embodiment, the first pulley 13 and the auxiliary arm 14 are arranged near the side edge at the end of the pallet 2, which can make the pallet 2 pull out as much area as possible. The supporting block 3 and the auxiliary arm 14 are arranged in a dislocation manner along the width direction of the pallet 2 to avoid obstruction between the auxiliary arm 14 and the supporting block 3 during the pulling process of the pallet 2.

[0033] Further, in this embodiment, both the first pulley 13 and the second pulley 15 are rotatably installed, and the first pulley 13 and the second pulley 15 are respectively in sliding contact with the inner walls of the first limiting guide groove 11 and the second limiting guide groove 12. During the pulling process of the pallet 2, the first pulley 13 and the second pulley 15 can respectively roll in the first limiting guide groove 11 and the second limiting guide groove 12, making the pulling of the pallet 2 as smooth as possible while providing auxiliary limiting support. Flanges are provided at the ends of the first pulley 13 and the second pulley 15 away from the pallet 2, and the flanges are in sliding contact with the surface of the guide plate 7 away from the pallet 2 for limiting the two ends of the pallet 2.

[0034] Working principle:

[0035] During use, by stacking multiple pallets 2 inside the frame formed by the four vertical arms 1, the occupied space is reduced. Moreover, with the support of the supporting blocks 3 on the four vertical arms 1 for the pallet 2, by pulling the pallet 2, the pallet 2 and the seedling-raising box 8 can be pulled out together from the inside of the frame formed by the four vertical arms 1, facilitating the planting and cultivation of tea saplings in the seedling-raising box 8 and making the operation convenient. Further, during the pulling process of the pallet 2, the first pulley 13 at the end of the pallet 2 rolls along the first limiting guide groove 11, and the second pulley 15 on the auxiliary arm 14 at the bottom of the pallet 2 rolls along the second limiting guide groove 12. Together with the reinforcing support arm 16 that is obliquely connected between the auxiliary arm 14 and the bottom of the pallet 2, it can provide auxiliary support for the pallet 2, improve the stability of the pallet 2, and keep the pulled-out pallet 2 as stable as possible, avoiding the problem that the seedling-raising box 8 drops due to the overweight of the seedling-raising box 8 when the pallet 2 is pulled out and the pallet 2 tilts downward, thus enhancing the performance of this seedling-raising rack.

[0036] All the technical features in this embodiment can be freely combined according to actual needs.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
