Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a liftable seedling rack. Background Technology

[0002] In agricultural production, seedling raising is a crucial step. Traditional seedling racks are mostly fixed structures, which have revealed numerous problems in practical use. For example, different types of seedlings have varying needs for light, ventilation, and operating space during their growth, and fixed-structure seedling racks cannot flexibly meet these diverse needs. When seedlings grow to a certain stage, because the spacing between the layers of the seedling rack is not adjustable, some seedlings may grow slowly due to insufficient light, or become susceptible to pests and diseases due to poor ventilation. At the same time, within a limited space, fixed-structure seedling racks are difficult to adjust flexibly according to the spatial layout, failing to make full use of space resources. Utility Model Content

[0003] The present invention mainly addresses the technical problems mentioned in the background art by providing a liftable seedling rack.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a liftable seedling rack, including a base frame, with wheels at the bottom of the base frame, and square support columns fixed at the four corners of the top of the base frame. Multiple seedling trays are arranged vertically between the four support columns. Each seedling tray has a bent flange around its bottom, and each seedling tray has a reinforcing fixing plate at its four corners. The reinforcing fixing plate and the bent flange have connecting grooves that mate with the inner walls of the support columns. The middle of the connecting groove and the inner corner of the support column have mutually cooperating locking fixing planes. A locking bolt is provided at the corresponding locking fixing plane on the reinforcing fixing plate. Each reinforcing fixing plate has an L-shaped adjusting sleeve covering the two outer walls of the support column on its outer side. The adjusting sleeve is fixed to the bent flange, and a second locking bolt is provided on the adjusting sleeve.

[0005] As a preferred embodiment, the outer edge of the adjusting sleeve is provided with a recessed connecting edge that is attached to the outer wall of the bent flange. The inner end of the recessed connecting edge is attached to the side wall of the supporting column, which facilitates the up-and-down sliding adjustment. The recessed connecting edge is provided with a fixing bolt. The outer ends of the reinforcing fixing angle plate are provided with fixing flanges that are attached to the inner wall of the bent flange. The fixing bolts pass through the bent flange and the fixing flange and are connected to fixing nuts, which can fix the adjusting sleeve plate, the bent flange and the reinforcing fixing angle plate into a whole, making the structure more stable.

[0006] As a preferred option, the inner side of the bent and folded edge is provided with an upward-facing L-shaped protective fold, which can form an inward-bent protective structure to prevent the operator's hand from being scratched at the edge when moving the seedling tray.

[0007] As a preferred option, each seedling tray has a fixing rib fixed along its length at the bottom, with the bottom ends of the fixing rib fixed to the top of the protective flange, increasing the overall strength of the seedling tray.

[0008] As a preferred embodiment, each seedling tray is fixed with L-shaped limiting strips around its top perimeter to prevent the seedling trays placed on the seedling trays from shifting on the seedling trays. Drainage gaps are provided between adjacent limiting strips to facilitate the drainage of excess water from the seedling trays.

[0009] As a preferred option, the bottom of the support column is fixed with a positioning boss, and the base frame is provided with a positioning groove that matches the positioning boss, which facilitates quick positioning of the support column during welding.

[0010] As a preferred embodiment, a pair of ear plates are fixed to the top of one end of the base frame, and a flipping shaft is rotatably installed between the pair of ear plates. Pull rods are fixed to both ends of the flipping shaft, and a traction sleeve is fixed to the other end of the pull rods, which can easily pull and move the device and can easily fix the position of the seedling rack.

[0011] As a preferred embodiment, the traction sleeve is equipped with a fixing pin, and the top of the base frame is equipped with a fixing hole for inserting the fixing pin. The inner wall of the fixing hole and the outer wall of the fixing pin are interference fit. When the traction sleeve is not in use, the fixing pin can be used to fix the traction sleeve to prevent shaking and noise when the seedling rack is moved.

[0012] This utility model has the following beneficial effects:

[0013] By loosening locking bolts one and two, the height of the seedling tray can be adjusted to meet the needs of seedlings at different growth stages for environmental factors such as light and ventilation. This allows for flexible adjustments based on the spatial layout, making full use of space resources. Each seedling tray has one corner secured by locking bolts one and two, ensuring a more secure lock and preventing loosening. Furthermore, each seedling tray has reinforced corner plates at its four corners, making the structure more stable. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: As Figure 1 -to Figure 6This utility model is a liftable seedling rack, including a base frame 6. The bottom of the base frame 6 is equipped with wheels. Square support columns 1 are fixed at the four corners of the top of the base frame 6. Multiple seedling trays 2 are arranged vertically between the four support columns 1. Each seedling tray 2 has a bent flange 10 around its bottom. Each seedling tray 2 has a reinforcing fixing plate 11 at each of its four corners. The reinforcing fixing plate 11 and the bent flange 10 have connecting grooves 15 that cooperate with the inner side wall of the support column 1. The middle of the connecting groove 15 and the inner corner of the support column 1 have mutually cooperating locking fixing planes 14. The reinforcing fixing plate 11 has a locking bolt 9 corresponding to the locking fixing plane 14. Each reinforcing fixing plate 11 has an L-shaped adjusting sleeve 4 covering the two outer walls of the support column 1. The adjusting sleeve 4 is fixed on the bent flange 10. The adjusting sleeve 4 has a locking bolt 5.

[0025] When in use, the height of the seedling tray 2 can be adjusted according to the type of seedling, its growth stage, and the actual operational needs. For example, when managing newly sown seedlings, since the seedlings are small and have relatively low light requirements, and in order to facilitate watering, fertilization, and other operations by staff, the locking bolts 9 and 5 on the corresponding seedling tray 2 can be loosened to adjust the spacing between adjacent seedling trays 2, and then the locking bolts 9 and 5 can be tightened.

[0026] When the seedlings grow to a certain stage and their need for light increases, loosen the locking bolts 9 and 5 on the corresponding seedling tray 2, increase the spacing between adjacent seedling trays 2 until the height allows the seedlings to receive sufficient light, and then tighten the locking bolts 9 and 5.

[0027] When placing the seedling tray, place the seedling tray on the seedling tray 2. During the seedling process, if it is necessary to move the seedling rack to another location, release the brakes on the walking wheels, push the seedling rack to the target location, and then lock the brakes on the walking wheels again to ensure that the seedling rack is placed stably.

[0028] In Example 2, based on Example 1, the outer side of the adjusting sleeve 4 is provided with a recessed connecting edge 8 that is attached to the outer wall of the bent flange 10. The inner end of the recessed connecting edge 8 is attached to the side wall of the supporting column 1. A fixing bolt is provided on the recessed connecting edge 8. The outer sides of both ends of the reinforcing fixing angle plate 11 are provided with fixing flanges 16 that are attached to the inner wall of the bent flange 10. The fixing bolts pass through the bent flange 10 and the fixing flanges 16 and are connected to fixing nuts. When installing the adjusting sleeve 4, the mounting holes on the recessed connecting edge 8 are aligned with the mounting holes on the bent flange 10, and then the fixing bolts and fixing nuts are inserted for fixation.

[0029] The inner side of the bending flange 10 is provided with an upward-facing L-shaped protective flange 13.

[0030] Each seedling tray 2 has a fixing rib 12 fixed along its length at the bottom, and the bottom ends of the fixing rib 12 are fixed to the top of the protective flange 13.

[0031] Each seedling tray 2 has L-shaped retaining strips 3 fixed around its top perimeter, with drainage gaps between adjacent retaining strips 3. When placing the seedling trays, the retaining strips 3 prevent displacement. Because of the drainage gaps between the retaining strips 3, excess water can drain away when watering the seedlings or during rainy weather (if the seedling rack is used outdoors), preventing water accumulation in the seedling trays and thus avoiding root rot.

[0032] A positioning boss 7 is fixed to the bottom of the support column 1, and a positioning groove that mates with the positioning boss 7 is provided on the base frame 6. When welding and fixing the support column 1, the positioning boss 7 is inserted into the positioning groove to complete the quick positioning, and then welding and fixing can be carried out.

[0033] A pair of ear plates are fixed to the top of one end of the base frame 6. A flipping shaft 20 is rotatably installed between the pair of ear plates. Pull rods 19 are fixed to both ends of the flipping shaft 20, and a traction sleeve 17 is fixed to the other end of the pull rods 19. When it is necessary to pull the seedling rack, the position of the bottom seedling tray 2 can be adjusted upward, and then the flipping shaft 20 can be rotated counterclockwise so that the traction sleeve 17 faces to the left. The traction sleeve 17 can then be hung on the towing vehicle for pulling. Alternatively, when it is necessary to fix the seedling rack outdoors, an insert rod is inserted into the traction sleeve 17 and then inserted into the ground to fix it.

[0034] The traction sleeve 17 is equipped with a fixing pin 18, and the top of the base frame 6 is equipped with a fixing hole for inserting the fixing pin 18. The inner wall of the fixing hole and the outer wall of the fixing pin 18 are interference fit. When the traction sleeve 17 is not in use, the fixing pin 18 can be inserted into the traction sleeve 17 and then inserted into the fixing hole for limiting and fixing.

[0035] 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.
