Description

Technical Field

[0001] This utility model relates to the field of agricultural facility technology, and in particular to a dual-purpose seedling tray structure for both blankets and pots. Background Technology

[0002] In agricultural production, seedling raising is a crucial step. Existing seedling trays are generally divided into blanket-type and pot-type trays. Blanket-type trays produce seedlings with dense, evenly distributed roots, suitable for mechanized transplanting, but the seedlings are generally weaker and have a longer recovery period after transplanting. Pot-type trays, on the other hand, produce robust seedlings with well-developed root systems, resulting in faster recovery and earlier greening after transplanting. However, pot-type trays have relatively lower sowing and transplanting efficiency and are difficult to implement on a large scale. Currently, there is a lack of seedling trays on the market that can combine the advantages of both blanket-type and pot-type trays, allowing for dual use, which to some extent limits the improvement of agricultural production efficiency and the reduction of planting costs. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dual-purpose seedling tray structure that can be used for both seedling trays and pots.

[0004] The purpose of this utility model is achieved through the following technical solution: a dual-purpose seedling tray structure, comprising:

[0005] A basic seedling tray is used for blanket-type seedling raising. Its bottom is a base surface, and several drainage holes are provided on the base surface so that excess water can be discharged through the drainage holes during the seedling raising process.

[0006] The movable seedling tray can be stretched and installed in the base seedling tray. The movable seedling tray is provided with a number of cavities that extend in the stretching direction. The cavities and the base surface form a pot for pot-type seedling raising.

[0007] The movable seedling tray is located above the base surface, and the distance between the movable seedling tray and the base surface does not exceed 3cm. The base seedling tray is rectangular. The movable seedling tray includes a scissor-type telescopic frame, a fixed plate installed at one end of the scissor-type telescopic frame, and a sliding plate installed at the other end of the scissor-type telescopic frame. The scissor-type telescopic frame is fixed to the end plate of the base seedling tray by the fixed plate, and the scissor-type telescopic frame extends and retracts due to the movement of the sliding plate. The base seedling tray has end plates on both sides along the extension direction of the movable seedling tray, and side plates on the other two sides. The scissor-type telescopic frame is composed of multiple pairs of X-shaped hinged rods. The ends of adjacent rods are hinged to form a mesh structure to achieve the linkage of extension and retraction of the scissor-type telescopic frame. The area enclosed between the rods is the cavity. It should be noted that in this application, the hinged connecting rods can also be replaced by an elastic telescopic net with telescopic function. The scissor-type telescopic frame is an elastic telescopic net with multiple cavities. That is, the movable seedling tray can also include an elastic telescopic net, a fixed plate installed at one end of the elastic telescopic net, and a sliding plate installed at the other end of the elastic telescopic net, with multiple cavities in the elastic telescopic net. Both the scissor-type telescopic frame and the elastic telescopic net need to meet certain support strength requirements. Since the scissor-type telescopic frame adopts a hinged structure, the connecting rods of the scissor-type telescopic frame can be made of stainless steel, rigid plastic, etc. Common rigid materials such as polypropylene (PP) boards and polyethylene (PE) boards are particularly suitable for seedling cultivation. Because the scissor-type telescopic frame has high strength, it can be reused repeatedly and is particularly suitable for mechanized production operations. The elastic telescopic net includes thermoplastic elastomers (such as TPE, TPU, TPV, etc.) and rubber materials (such as natural rubber, styrene-butadiene rubber, etc.). Utilizing the plasticity of the materials themselves, the manufacturing cost is low and replacement is convenient.

[0008] The sliding plate is equipped with a slider for sliding in the groove, and both side plates are equipped with grooves for stretching the movable seedling tray. A first positioning hole is provided on the end face of the sliding plate facing the end plate, and a first fixing hole corresponding to the first positioning hole is provided on the end plate. When the sliding plate slides to its maximum stroke position, the first positioning hole and the first fixing hole align and are locked by a fixing component. It should be noted that, preferably, the sliding plate contacts the end plate when it slides to its maximum stroke position. If there is a certain distance between the sliding plate and the end plate, a connecting bolt of corresponding length can be used. Since the first positioning hole and the first fixing hole use hole-to-hole positioning, they can be connected by a screw. The first positioning hole is a through hole, and the first fixing hole is a threaded hole. The first positioning hole and the first fixing hole can be fixed with bolts and nuts. An operating pull rod is provided on the sliding plate, located on the upper end face for easy operation. When compressed, the width of the scissor-type telescopic frame is smaller than the width of the basic seedling tray.

[0009] This invention combines a basic seedling tray with a stretchable movable seedling tray, integrating blanket-style and pot-style seedling cultivation. Both ends of the scissor-type telescopic frame are detachably connected (bolt assembly) to a fixed plate and a sliding plate, respectively. When blanket-style seedling cultivation is needed, the scissor-type telescopic frame is compressed to its minimum stroke (the sliding plate has a second first positioning hole for fixing, and the side plate has a second first fixing hole corresponding to the second first positioning hole; the scissor-type telescopic frame is locked when at its minimum stroke; see the fixing of the first positioning hole and the first fixing hole for details). At this point, the basic seedling tray is the actual seedling tray used for practical purposes. When pot-style seedling cultivation is needed, the scissor-type telescopic frame is stretched to its maximum stroke, and the sliding plate is fixed to the end plate. The cavity and base surface of the scissor-type telescopic frame form a pot for pot-style seedling cultivation. The height of the cavity (scissor-type telescopic frame) is generally not less than 10cm, and the effective planting height of the pot is generally 7-8cm. When the scissor-type telescopic frame is extended to its maximum stroke, the resulting cavity is square. During compression, this cavity tightens as the scissor-type telescopic frame is compressed. Since the scissor-type telescopic frame can be detached from the base seedling tray, different seedling trays can be replaced by changing the size of the scissor-type telescopic frame.

[0010] The beneficial effects of this utility model are: (1) A stretchable movable seedling tray is set on the basic seedling tray, which combines the blanket seedling raising and the pot seedling raising. A stretchable pot seedling raising tray is formed on the basis of the blanket seedling raising tray, realizing the dual use of blanket and pot seedling, improving the efficiency and quality of seedling raising, reducing the cost of agricultural production, and is especially suitable for mechanized production; (2) The two ends of the movable seedling tray are detachable, which is suitable for seedling varieties of different specifications, greatly improving the versatility and practicality of the seedling raising tray, and meeting the needs of different planting scenarios and planting methods.

Detailed Implementation

[0022] The technical solution of this utility model is described in further detail below with reference to the accompanying drawings and embodiments, but the protection scope of this utility model is not limited to the following description.

[0023] Example 1

[0024] like Figures 1-3 As shown, a dual-purpose seedling tray structure includes:

[0025] A basic seedling tray 1 is used for blanket-type seedling raising, and its bottom is a base surface 2, on which several drainage holes 3 are provided;

[0026] The movable seedling tray 4 is stretchably installed in the base seedling tray 1. The movable seedling tray 4 is provided with a plurality of cavities 5 that extend in the stretching direction. The cavities 5 and the base surface 2 form a pot for pot-type seedling raising.

[0027] The movable seedling tray 4 is located above the base surface 2 and is in contact with the base surface 2. The base seedling tray 1 is a rectangular tray.

[0028] The movable seedling tray 4 includes a scissor-type telescopic frame 401, a fixed plate 402 installed at one end of the scissor-type telescopic frame 401, and a sliding plate 403 installed at the other end of the scissor-type telescopic frame 401. The scissor-type telescopic frame 401 is fixed to the end plate 101 of the base seedling tray 1 by the fixed plate 402. The scissor-type telescopic frame 401 is extended and retracted by the movement of the sliding plate 403. The base seedling tray 1 has end plates 101 on both sides along the stretching direction of the movable seedling tray 4, and side plates 102 on the other two sides. The height of the sliding plate 403 does not exceed the height of the side plate 102.

[0029] like Figures 4-7 As shown, the scissor-type telescopic frame 401 is composed of multiple pairs of X-shaped hinged connecting rods 404. The ends of adjacent connecting rods 404 are hinged to form a mesh structure to achieve the telescopic linkage of the scissor-type telescopic frame 401. The area enclosed between the connecting rods 404 is the cavity 5 (the area not enclosed is not considered as the pot body, such as the connection between the edge connecting rods 404 and the sliding plate 403 and the fixed plate 402). The sliding plate 403 is provided with a slider 405 for sliding in the sliding groove 103. Both sides of the side plate 102 are provided with sliding grooves 103 for stretching the movable seedling tray 4. The sliding grooves 103 are T-shaped grooves, and the sliders 405 are matched with them. The sliding plate 403 has a first positioning hole 406 on its end face facing the end plate 101. The end plate 101 has a first fixing hole 105 corresponding to the first positioning hole 406. When the sliding plate 403 slides to its maximum stroke position, the first positioning hole 406 and the first fixing hole 105 are aligned and locked by a fixing component. There are multiple first positioning holes 406, and the number of first fixing holes 105 matches the number of positioning holes 406. When locking, one or more of them can be aligned and fixed. The sliding plate 403 has a pull rod 407 for operation. When compressed, the width of the scissor-type telescopic frame 401 is smaller than the width of the base seedling tray 1.

[0030] Common seedling tray dimensions are 600mm*300mm*30mm, with internal dimensions of 580mm*280mm*30mm. However, since a movable seedling tray needs to be installed on the basic seedling tray, its height increases. In this application, the external dimensions of the basic seedling tray are 600mm*300mm*45mm, and the internal dimensions are 580mm*280mm*42mm. Before use, the fixing plate 402, the scissor-type telescopic frame 401, and the sliding plate 403 are installed in the basic seedling tray, and the slider 405 is placed into the sliding groove 103. During blanket-type seedling raising, the scissor-type telescopic frame 401 is not stretched. The position of the scissor-type telescopic frame 401 is locked by installing locking components (bolts) on the second positioning hole 408 on the side wall of the sliding plate 403 and the second fixing hole 104 on the side plate 102 (the sliding plate 403 is relatively long, and the second fixing hole 104 is a non-through threaded hole, with the second fixing hole 104 provided above and below the sliding groove 103). The second positioning hole 408 is a through hole and corresponds to the second fixing hole 104. At this time, the base surface 2 of the foundation seedling tray 1 is used for blanket-type seedling raising. During pot-type seedling raising, the sliding plate 403 is moved by the pull rod 407 until the scissor-type telescopic frame 401 reaches its maximum forming position. Then, the sliding plate 403 is fixed to the end plate 101 by locking components (bolts). At this time, the cavity 5 in the scissor-type telescopic frame 401 has the largest volume and forms a pot for pot-type seedling raising with the base surface 2. At this time, the seedling raising is switched from blanket-type seedling raising to pot-type seedling raising. Remove the sliding plate 403 from the end plate 101, compress the shear telescopic frame 401 to its original state and lock it, thus realizing the switch from pot-type seedling raising to blanket-type seedling raising.

[0031] Example 2

[0032] like Figure 8 As shown, the scissor-type telescopic frame 401 in Example 1 is replaced with an elastic telescopic net, which has multiple cavities 5. The remaining structure and working principle are the same as in Example 1.

[0033] Example 3

[0034] like Figures 9-10 As shown, the mesh structure formed by the hinged ends of adjacent connecting rods 404 in Embodiment 1 is replaced with multiple independent scissor telescopic units. Each scissor telescopic unit consists of connecting rods 404 that are hinged together in an X-shape. The area enclosed by the connecting rods 404 is the cavity 5. All scissor telescopic units are simultaneously mounted on the fixed plate 402 and simultaneously driven by the sliding plate 403. The remaining structure and working principle are the same as in Embodiment 1. In this embodiment, a single damaged scissor telescopic unit can be replaced individually, without needing to replace the entire scissor telescopic frame 401.

[0035] As illustrated above with reference to the accompanying drawings, one embodiment of the present invention has been described by way of example. However, those skilled in the art should understand that various improvements can be made to the embodiment proposed above without departing from the scope of the present invention, or equivalent substitutions can be made to some of the technical features.
