Description

Technical Field

[0001] This utility model relates to the field of seedling equipment technology, and in particular to a flip-type seedling tray that facilitates seedling removal. Background Technology

[0002] Seedling trays, as a key tool in modern agricultural production, are widely used in the large-scale, intensive seedling cultivation of crops such as vegetables, flowers, and trees. By cultivating seedlings centrally in the seedling holes of the trays, it is convenient to manage water and fertilizer and control the environment uniformly. Once the seedlings have grown to a suitable stage, they need to be removed from the trays and transplanted to the field or larger containers.

[0003] However, existing seedling trays generally have structural deficiencies in the seedling removal process. Traditional seedling trays are usually one-piece structures, designed primarily for the seedling process, without optimizing for ease and safety in seedling removal. When seedlings need to be removed, operators typically have to use manual methods, such as pushing them upwards through the drainage holes at the bottom of the tray with their fingers, or using tools to dig the seedlings and substrate together from above the seedling holes.

[0004] This method of seedling removal, which relies on external tools or purely manual labor, has significant drawbacks. Due to the difficulty in precisely controlling force and angle, the process of pushing or digging easily leads to the separation of seedling roots from the substrate clump, or directly causes mechanical damage to the roots, such as tearing or breaking. Damaged roots severely affect the seedling recovery speed and survival rate after transplanting, thus adversely impacting the overall efficiency of agricultural production. The root of the problem lies in the lack of auxiliary structures for seedling removal in existing seedling trays, forcing operators to use this rough and easily damaging method. Therefore, this invention proposes a flip-type seedling tray that facilitates seedling removal to address the shortcomings of existing technology. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a flip-type seedling tray that facilitates seedling removal, aiming to improve the problems of inconvenient seedling removal and easy damage to seedling roots caused by structural limitations in some existing flip-type seedling trays.

[0006] This utility model provides a flip-type seedling tray for easy seedling removal, including a seedling tray, a support plate slidably connected to the bottom of the seedling tray, and a push-out mechanism disposed inside the seedling tray.

[0007] The ejection mechanism includes an ejection assembly, which consists of a linkage frame, an ejection head connected to the linkage frame, a spring, and a retaining ring.

[0008] Furthermore, the fixing ring is fixed to the inner wall of the bottom of the seedling hole in the seedling tray, the spring surrounds the outer periphery of the rod of the ejector head, and the two ends of the spring abut against the inner bottom surface of the fixing ring and the bottom surface of the head of the ejector head, respectively; the tray is used to abut against and restrict the ejector head to compress the spring in the inserted state, and to release the ejector head in the withdrawn state. Through the structural combination, the seedling picking action is automated and non-destructive.

[0009] Preferably, the ejection mechanism further includes a handle, which is inserted through the side wall of the seedling tray and fixedly connected to the linkage frame. The handle is used to drive the linkage frame and all ejection heads to reset synchronously by pulling, thus simplifying the reset process of the seedling tray.

[0010] Preferably, the linkage frame has a hollow structure to reduce its own weight, and the ends of multiple ejector heads are fixedly connected to the linkage frame one by one. The structure ensures that during the ejection operation, all seedlings in the seedling holes can be ejected synchronously and smoothly.

[0011] Preferably, the flip-type seedling tray for easy seedling removal also includes a rotating mechanism, which includes a base, on which the seedling tray is directly placed to obtain stable support and a basis for subsequent rotation.

[0012] Preferably, the rotating mechanism further includes a support frame and a rotating shaft rotatably mounted on the support frame, with the bottom support fixedly connected to the rotating shaft, so that the seedling tray can be flipped with the rotating shaft, making it convenient for the user to operate from different angles.

[0013] Preferably, the rotating mechanism further includes a second base with the same structure as the base, which is also fixedly connected to the rotating shaft to support another seedling tray; and also includes a pull column and a fixing pin for linking the two bases, providing a structural basis for multi-tray linkage.

[0014] Preferably, the pulling column is rotatably connected to the side edge of the base via a fixing pin, and the other end of the pulling column is connected to the corresponding side edge of the second base, thereby forming a sophisticated linkage mechanism that can drive the other to rotate synchronously when one of the seedling trays is rotated.

[0015] Preferably, the support frame specifically includes a base for stable placement and a column extending vertically upward from the base, with the rotating shaft horizontally installed at the top of the column. This design ensures that the entire device maintains good structural stability and operational safety when carrying multiple seedling trays filled with substrate.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up an ejection mechanism consisting of a pull-out tray, a spring and an ejection head, solves the problem that manual seedling removal in the prior art easily damages the seedling root system, and achieves the technical effect of non-destructive, fast and batch seedling removal, significantly ensuring the integrity of the seedlings and the transplant survival rate.

[0017] 2. This utility model, by setting up a rotating mechanism consisting of a support frame, a rotating shaft and linkage components, realizes the synchronous flipping operation of multiple seedling trays, which solves the problems of inconvenient management and low operating efficiency of multiple seedling trays in the prior art, and achieves the technical effects of intensive management, improved space utilization and convenient operation for users.

[0018] 3. This utility model, by organically combining the ejection mechanism and the rotation mechanism, has a reasonable overall structural design and clear operating logic, which solves the problems of complex traditional seedling cultivation processes and high labor intensity. It achieves the technical effect of simplifying operation and reducing labor costs, and has strong practicality and promotion value. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example: Reference Figures 1 to 5 This utility model provides a flip-type seedling tray that facilitates seedling removal, aiming to solve the problem that the existing seedling trays are inconvenient to remove seedlings and easily damage the seedling roots due to their own structural limitations.

[0023] like Figures 1 to 4 As shown, the flip-type seedling tray for easy seedling removal includes a seedling tray 1 and a support plate 23 slidably connected to the bottom of the seedling tray 1. The seedling tray 1 is equipped with an ejection mechanism 2. The support plate 23 controls the locking and releasing of the ejection mechanism 2. The ejection mechanism 2 includes an ejection assembly 22, which consists of a linkage frame 221, an ejection head 222, a spring 223, and a fixing ring 224. The fixing ring 224 is fixed to the inner wall of the bottom of the seedling holes in the seedling tray 1, and the spring 223 surrounds the seedling holes. The outer periphery of the rod of the ejector head 222 and the two ends of the spring 223 respectively abut against the inner bottom surface of the fixing ring 224 and the bottom surface of the head of the ejector head 222. The end of the ejector head 222 is fixedly connected to the linkage frame 221. When the tray 23 is in the inserted state, its plate abuts against and restricts the ejector head 222, so that the spring 223 is compressed. When it is necessary to take the seedling, the tray 23 is pulled out, the restriction on the ejector head 222 is released, and the spring 223 extends and drives the ejector head 222 to move upward.

[0024] Reference Figure 2 , Figure 4 and Figure 5 The ejection mechanism 2 also includes a handle 21, which is inserted through the side wall of the seedling tray 1 and fixedly connected to the linkage frame 221. The linkage frame 221 is a hollow structure, and the ends of multiple ejection heads 222 are fixedly connected to the linkage frame 221. By pulling the handle 21, the linkage frame 221 can be moved, thereby causing all ejection heads 222 to reset synchronously and compress the spring 223 again. The flip-type seedling tray that facilitates seedling removal also includes a rotating mechanism 3. The seedling tray 1 is set on the base 33 of the rotating mechanism 3. The rotating mechanism 3 also includes a support frame 31 and a rotating shaft 32 rotatably mounted on the support frame 31. The base 33 is fixedly connected to the rotating shaft 32, so that the seedling tray 1 can rotate together with the rotating shaft 32 through the base 33.

[0025] Reference Figure 5To achieve synchronous rotation of multiple seedling trays 1, the rotating mechanism 3 also includes a second base 33 with the same structure as the base 33. Both the second base 33 and the base 33 are fixedly connected to the rotating shaft 32. The rotating mechanism 3 also includes a pulling column 34 and a fixing pin 35. The pulling column 34 is rotatably connected to the side edge of the base 33 through the fixing pin 35. The other end of the pulling column 34 is connected to the corresponding side edge of the second base 33, thereby forming a linkage. As another preferred embodiment, in order to improve the overall stability of the rotating mechanism 3, the support frame 31 specifically includes a base for stable placement and a column extending vertically upward from the base. The rotating shaft 32 is horizontally installed at the top of the column.

[0026] The implementation principle of this application embodiment is as follows: When it is necessary to remove the seedlings, the bottom plate 23 of the seedling tray 1 is pulled out along its sliding direction. As the plate 23 is moved out, the ejector head 222, which was originally resisted and restricted by the plate, is unrestrained. The elastic potential energy stored in the spring 223 is released, driving the ejector head 222 to move upward and pass through the hole at the bottom of the seedling tray 1, thus completely ejecting the seedlings and substrate from the seedling hole. After removing the seedlings, the handle 21, which is fixedly connected to the linkage frame 221, is pulled. The linkage frame 221 drives all the ejector heads 222 to return to their original position simultaneously, recompressing the spring 223. At this time, the plate 23 is inserted back into its original position, and the ejector mechanism 2 can be locked again.

[0027] When it is necessary to pick up or operate different seedling trays 1, move one of the seedling trays 1. The seedling tray 1 will drive the base 33 below it to rotate around the rotating shaft 32. During the rotation, the pulling column 34 connected to the base 33 through the fixing pin 35 will be driven, thereby pulling or pushing the other end connected to the second base 33, so that the second base 33 and the seedling tray 1 above it will rotate synchronously. The entire rotating mechanism 3, supported by the support frame 31, achieves the purpose of synchronously rotating multiple seedling trays 1, which is convenient for users to carry out intensive operation.
