Description

Technical Field

[0001] This application relates to the field of seedling transplanting technology, specifically to a mechanical clamp for preventing damage during transplanting of vegetable plug seedlings. Background Technology

[0002] In the vegetable cultivation industry, transplanting seedlings into plug trays is a crucial step. Traditional methods of transplanting vegetable plug tray seedlings have several drawbacks. Manual transplanting relies on fingers to directly grasp the seedlings, making it difficult to ensure the integrity of the root system and soil layer, easily leading to seedling damage and affecting survival rates. Furthermore, manual operation is inefficient and cannot meet the needs of large-scale planting. Some existing transplanting machinery has an inadequate structural design, unable to accurately adapt to the shape of the plug tray seedlings and the structure of the tray. Transplanting clamps are prone to instability when grasping seedlings, causing them to fall during transplanting. In addition, the force between the machinery and the plug tray is difficult to control during transplanting, often resulting in damage to the plug tray due to excessive force.

[0003] Therefore, in order to improve the efficiency and quality of vegetable planting, there is a need for a mechanical clamp for transplanting vegetable seedlings from seedling trays that can stably grasp seedlings, is easy to operate, and does not easily damage seedlings and seedling trays. Summary of the Invention

[0004] In response to the above-mentioned technical problems, this application solves the problems that when transplanting vegetable seedlings from plug trays, the seedlings are not firmly grasped, the transplanting operation is difficult, and the seedlings and plug trays are easily damaged.

[0005] To achieve the above objectives, the technical solution adopted in this application is: a mechanical clamp for preventing damage during transplanting of vegetable seedlings in plug trays, comprising a support component, a transplanting component, a limiting component, a control component, and a reset component. The transplanting component slides at an angle on the support component. The limiting component is used to restrict the sliding of the transplanting component and maintain its stability. The control component is used to control the sliding of the transplanting component. The reset component is disposed inside the control component and the support component and is used to reset the control component.

[0006] The support assembly includes an outer support rod, a vertical support rod, and an inner support rod. The vertical support rod and the inner support rod are fixedly installed on the outer support rod. The outer support rod, the vertical support rod, and the inner support rod are all L-shaped structures, and an inclined surface is provided on the end of the inner support rod away from the outer support rod. This inclined surface is used for the sliding of the transplanting assembly.

[0007] The transplanting assembly includes a connecting plate, and three insert plates are provided, which slide at the two ends of the L-shaped structure of the inner support rod and at the corner, respectively. The insert plates are L-shaped and match the structure at the corner of the inner support rod.

[0008] Preferably, the control assembly includes an inner connecting rod, a top plate, and an outer limiting plate. The inner connecting rod is slidably disposed on the inner side of the vertical support rod. The top plate is fixedly installed on the end of the inner connecting rod away from the outer support rod. The outer limiting plate and the outer sliding plate are interlocked to form a vertical cylinder. The vertical cylinder is sleeved on the vertical support rod and the reset assembly, and the vertical cylinder is fixedly connected to the top plate.

[0009] Preferably, the control component includes an inner slide plate, which is fixedly connected to a vertical support rod. The inner slide plate is disposed inside the outer slide plate, and the outer slide plate slides vertically on the inner slide plate.

[0010] Preferably, the reset assembly includes an upper telescopic rod, a lower telescopic rod, and a spring. The upper telescopic rod is fixedly connected to the top plate, and the lower telescopic rod is fixedly mounted on the vertical support rod. The upper telescopic rod is sleeved on the lower telescopic rod, and the upper and lower telescopic rods form a telescopic rod. The spring is sleeved on the telescopic rod, and the control assembly is reset through the spring and the telescopic rod.

[0011] Preferably, the support assembly includes a central baffle, which is fixedly mounted on a vertical support rod and fixedly connected to the reset assembly. The central baffle is used to support the bottom end of the reset assembly.

[0012] Preferably, the support assembly includes a central support plate, which is fixedly installed on a vertical support rod. The central support plate is located outside the vertical support rod, and the vertical support rod is used by the operator to control the movement of the support assembly after the transplanting assembly is inserted.

[0013] Preferably, the transplanting assembly includes a connecting plate located at the top of the insert plates and slidably connected to the three insert plates. The connecting plate is located below the inner connecting rod, and an extension plate is provided at one end of the inner connecting rod near the connecting plate. The connecting plate and the extension plate are slidably connected horizontally. The extension plate is used by the inner connecting rod to push the connecting plate and the transplanting assembly to move.

[0014] Preferably, the transplanting assembly includes three sliders, which are respectively fixedly installed on the sliding parts of the three insert plates on the outer support rod. The two outer sides of the L-shaped structure of the insert plates are provided with sliding grooves that match the sliders.

[0015] Preferably, the limiting component includes a vertical sliding frame and a horizontal sliding rod. The vertical sliding frame is fixedly installed on the outer support rod and has a vertical sliding groove.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] like Figures 1 to 6 As shown, the vegetable seedling transplanting anti-damage mechanical clamp includes a support component 100, a transplanting component 200, a limiting component 300, a control component 400, and a reset component 500. The transplanting component 200 slides inclined on the support component 100. The limiting component 300 is used to restrict the sliding of the transplanting component 200 and maintain the stability of the transplanting component 200. The control component 400 is used to control the sliding of the transplanting component 200. The reset component 500 is disposed inside the control component 400 and the support component 100 and is used to reset the control component 400.

[0031] Specifically, the staff holds the control component 400 and moves the support component 100 to the seedling to be transplanted in the seedling tray. Because the hole in the seedling tray has an inverted conical protrusion structure, the transplanting component 200 is tilted on the support component 100. When the control component 400 pushes the transplanting component 200 downward, the transplanting component 200 tilts and slides on the support component 100, inserting into the hole in the seedling tray, separating the outer end of the seedling from the seedling tray. Then, the staff controls the support component 100 to tilt at a certain angle, and uses the support component 100 to drive the transplanting component 200 to gently tap the soil layer of the seedling, making it slide upward along the inclined surface in the hole of the seedling tray until it is detached from the seedling tray.

[0032] like Figure 2 As shown, the support assembly 100 includes an outer support rod 101, a vertical support rod 102, and an inner support rod 104. The vertical support rod 102 and the inner support rod 104 are fixedly installed on the outer support rod 101. The outer support rod 101, the vertical support rod 102, and the inner support rod 104 are all L-shaped structures, and an inclined surface is provided on the end of the inner support rod 104 away from the outer support rod 101. This inclined surface is used for the sliding of the transplanting assembly 200.

[0033] Specifically, when using it, the outer support rod 101 is placed on the seedling tray. Because the outer support rod 101 has an L-shaped structure and the outer support rod 101 is the same size as the seedling tray opening, the two rods of the outer support rod 101 are placed on one corner of the upper end of the seedling tray opening. When using it, the transplanting component 200 can be inserted into the three corners of the seedling soil layer, making it convenient to grasp the seedling.

[0034] like Figure 2 As shown, the transplanting assembly 200 includes a connecting plate 201 and three insert plates 202, which slide at the two ends of the L-shaped structure of the inner support rod 104 and at the corner, respectively. The insert plates 202 are L-shaped and match the corner structure of the inner support rod 104.

[0035] Specifically, the L-shaped structure of the insert plate 202 is designed to adapt to the shape of the seedling's corners, allowing one insert plate 202 to support two sides of the seedling. Three insert plates 202 support multiple corners of the seedling, ensuring the seedling receives sufficient force from multiple angles and preventing soil collapse. The lower end of the insert plate 202 has a chamfered angle, allowing it to be easily inserted into the space between the seedling and the seed tray.

[0036] like Figures 2 to 6 As shown, the control component 400 includes an inner connecting rod 401, a top plate 402, and an outer limiting plate 403. The inner connecting rod 401 is slidably disposed on the inner side of the vertical support rod 102. The top plate 402 is fixedly installed on the end of the inner connecting rod 401 away from the outer support rod 101. The outer limiting plate 403 and the outer sliding plate 404 are interlocked to form a vertical cylinder. The vertical cylinder is sleeved on the vertical support rod 102 and the reset component 500, and the vertical cylinder is fixedly connected to the top plate 402.

[0037] Specifically, the vertical projections of the top plate 402, the outer limiting plate 403, and the outer sliding plate 404 cover the vertical projection of the vertical support rod 102, so that the vertical cylinder formed by the outer limiting plate 403 and the outer sliding plate 404 slides vertically on the vertical support rod 102, and isolates and protects the reset component 500 inside the vertical support rod 102, preventing external soil and other dust from entering the interior of the vertical cylinder and affecting the reset component 500's reset of the control component 400.

[0038] In use, the operator holds the outer limiting plate 403 and the outer sliding plate 404 with their hands and controls the top plate 402 to slide downward. The top plate 402 pushes the inner connecting rod 401 to slide downward on the vertical support rod 102, and the inner connecting rod 401 pushes the transplanting component 200 to slide on the inclined surface of the outer support rod 101.

[0039] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the control component 400 includes an inner slide plate 405, which is fixedly connected to the vertical support rod 102. The inner slide plate 405 is disposed inside the outer slide plate 404, and the outer slide plate 404 slides vertically on the inner slide plate 405.

[0040] Specifically, when the vertical cylinder formed by the outer limit plate 403 and the outer slide plate 404 moves downward, the vertical cylinder slides vertically on the outer end face of the vertical support rod 102 and the inner slide plate 405. The vertical cylinder, the vertical support rod 102 and the inner slide plate 405 shield the reset assembly 500 to prevent external debris from entering and affecting the operation of the reset assembly 500.

[0041] like Figures 3 to 5 As shown, the reset assembly 500 includes an upper telescopic rod 501, a lower telescopic rod 502, and a spring 503. The upper telescopic rod 501 is fixedly connected to the top plate 402, and the lower telescopic rod 502 is fixedly mounted on the vertical support rod 102. The upper telescopic rod 501 is sleeved on the lower telescopic rod 502, and the upper telescopic rod 501 and the lower telescopic rod 502 form a telescopic rod. The spring 503 is sleeved on the telescopic rod, and the control assembly 400 is reset through the spring 503 and the telescopic rod.

[0042] Specifically, when the vertical cylinder moves downward, it drives the top plate 402 to push the upper end of the telescopic upper rod 501 and compress the spring 503. This causes the telescopic upper rod 501 to slide downward on the telescopic lower rod 502, adapting to the movement of the vertical cylinder. After the seedlings are removed from the seedling tray, the staff releases control of the vertical cylinder, and the spring force of the spring 503 pushes the top plate 402 upward to reset it.

[0043] like Figures 3 to 6 As shown, the support assembly 100 includes a central baffle 105, which is fixedly installed on the vertical support rod 102. The central baffle 105 is fixedly connected to the reset assembly 500 and is used to support the bottom end of the reset assembly 500.

[0044] Specifically, a space is provided between the central baffle 105 and the vertical support rod 102 for the vertical support rod 102 to move. The central baffle 105 provides fixed support for the lower end of the telescopic lower rod 502, allowing the spring 503 fitted on it to accumulate elastic force for subsequent reset. The central baffle 105, the inner sliding plate 405, the inner connecting rod 401, and the vertical support rod 102 together isolate the space above the central baffle 105.

[0045] like Figures 2 to 6As shown, the support assembly 100 includes a central support plate 103, which is fixedly installed on the vertical support rod 102. The central support plate 103 is located outside the vertical support rod 102. The vertical support rod 102 is used by the staff to control the movement of the support assembly 100 after the transplanting assembly 200 is inserted.

[0046] Specifically, the vertical movement of the vertical cylinder is restricted by the central support plate 103. When the vertical cylinder moves downwards on the vertical support rod 102, it contacts the central support plate 103, which stops its downward movement. At this point, the operator can use their fingers to grip the lower end of the central support plate 103, thereby tilting the entire device and pushing the seedling in the seedling tray, causing it to slide along the tilted surface of the tray and detach from it. The operation of gripping the central support plate 103 reduces the force applied to the seedling tray body during tilting, concentrating the force on the upper part of the vertical support rod 102. This utilizes the upper end of the seedling tray hole as a fulcrum, leveraging the principle to pry the seedling off, thus preventing damage to the seedling tray or other components due to excessive force.

[0047] like Figure 2 As shown, the transplanting assembly 200 includes a connecting plate 201, which is located at the top of the insert plates 202. The connecting plate 201 is slidably connected to the three insert plates 202. The connecting plate 201 is located below the inner connecting rod 401. An extension plate is provided at one end of the inner connecting rod 401 near the connecting plate 201. The connecting plate 201 is horizontally slidably connected to the extension plate. The extension plate is used by the inner connecting rod 401 to push the connecting plate 201 and the transplanting assembly 200 to move.

[0048] Specifically, the connecting plate 201 is slidably connected to the upper ends of the three insert plates 202, controlling the synchronous movement of the three insert plates 202 and restricting the upper ends of the three insert plates 202 to make them slide stably on the slider 203. The extension plate of the inner connecting rod 401 can vertically push the connecting plate 201 to move, and the connecting plate 201 can also slide on the horizontal surface of the extension plate of the inner connecting rod 401.

[0049] In use, the vertical cylinder pushes the inner connecting rod 401, and the extension plate at the lower end of the inner connecting rod 401 pushes the connecting plate 201 to slide downward. The connecting plate 201 pushes the three insert plates 202 to slide obliquely on the inclined surface of the inner support rod 104. When the insert plates 202 slide, the position of their upper ends gradually changes, so that the upper ends of the two outer insert plates 202 slide on the lower end surface of the connecting plate 201, while the insert plate 202 at the corner of the connecting plate 201 moves away from the vertical support rod 102. The insertion plates 202 adapt to the displacement of the end horizontal surface caused by the sliding of the tapered inclined direction.

[0050] like Figure 2 and Figure 3 As shown, the transplanting assembly 200 includes three sliders 203, which are respectively fixedly installed on the sliding parts of the three insert plates 202 on the outer support rod 101. The two outer sides of the L-shaped structure of the insert plate 202 are provided with sliding grooves, which match the sliders 203.

[0051] Specifically, the movement of the insert plate 202 is restricted by the cooperation of the groove on the outer side of the insert plate 202 and the slider 203, so that it is stably inserted into the space between the seedling and the seedling tray on the inclined surface of the inner support rod 104.

[0052] like Figure 2 and Figure 3 As shown, the limiting component 300 includes a vertical sliding frame 301 and a horizontal sliding rod 302. The vertical sliding frame 301 is fixedly installed on the outer support rod 101, and a vertical sliding groove is provided on the vertical sliding frame 301. The horizontal sliding rod 302 is fixedly connected to the transplanting component 200 and slides on the vertical sliding groove of the vertical sliding frame 301. The horizontal sliding rod 302 is used to limit the movement of the transplanting component 200.

[0053] Specifically, each of the two rods of the L-shaped structure of the connecting plate 201 is equipped with a limiting component 300. When the connecting plate 201 is pushed by the inner connecting rod 401, the connecting plate 201 drives the horizontal slide rod 302 to slide vertically downward on the vertical slide groove of the vertical sliding frame 301. When the connecting plate 201 is displaced on the horizontal plane due to the tapered angle sliding of the insert plate 202, the connecting plate 201 slides on the extension plate of the inner connecting rod 401, thereby pulling the horizontal slide rod 302 to slide laterally on the vertical slide groove of the vertical sliding frame 301.

[0054] like Figure 2 and Figure 3 As shown, the limiting component 300 includes a nut 303 and a stabilizing rod 304. The nut 303 is threadedly installed on the horizontal slide bar 302 at one end away from the transplanting component 200. The nut 303 is used to limit the distance the transplanting component 200 moves in the horizontal direction.

[0055] Specifically, the stabilizer 304 is fixedly connected to the vertical support rod 102 and the vertical sliding frame 301, and the stabilizer 304 is used to stabilize the vertical sliding frame 301. The nut 303 restricts the lateral sliding of the horizontal slide bar 302 on the vertical slide groove of the vertical sliding frame 301, limiting its movement distance.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
