Description

Technical Field

[0001] This utility model relates to the field of agricultural planting equipment technology, and in particular to an isolation-type anti-immersion seedling tray for flue-cured tobacco black shank disease. Background Technology

[0002] Black shank in flue-cured tobacco is a common soil-borne disease in tobacco cultivation. Its occurrence is related to soil moisture, and it can spread through soil and water. In common seedling trays, if water seeps directly through the drainage holes during watering, it is difficult to control the humidity. If the holes are blocked, the seedling substrate will remain overly wet for a long time, creating conditions for pathogen reproduction and spread. Therefore, it is necessary to develop a seedling device with adjustable drainage and the ability to isolate the seedlings to block the spread of pathogens. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that create conditions for the reproduction and spread of pathogens, and to propose an isolation-type anti-immersion seedling tray for flue-cured tobacco black shank disease.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flue-cured tobacco black shank disease isolation and anti-waterlogging seedling tray includes a water receiving tray and a placement frame located on top. The water receiving tray and the placement frame are fixedly connected by multiple support pillars, and the bottom of the water receiving tray is provided with drainage holes.

[0006] The seedling tray is embedded in the placement frame from above. The seedling tray has multiple planting troughs arranged in a matrix, and each planting trough has a drainage hole at the bottom.

[0007] A sealing plate is located below the seedling tray. The surface of the sealing plate has multiple connecting holes, each of which is matched with a corresponding drainage hole.

[0008] The system allows the connecting hole to be connected to or misaligned with the drainage hole by moving the sealing plate, thus controlling the opening and closing of the drainage hole. Excess water is discharged through the drainage hole and connecting hole to the water receiving tray and then discharged through the drain hole. At the same time, the structure of the seedling tray with gaps and separations prevents pathogens from spreading through the soil.

[0009] In one possible design, a side shell is fixedly connected to the water receiving tray and the placement frame on the same side. A sliding plate is slidably arranged inside the side shell. An oblique guide hole is opened on the surface of the sliding plate. A bracket is fixedly arranged on one side of the sealing plate. The bracket extends into the side shell and is fixedly connected to a guide rod. One end of the guide rod is located in the oblique guide hole.

[0010] In one possible design, an auxiliary plate is fixedly connected to the other side of the water receiving tray and the placement frame, and a limit strip is fixedly provided on the other side of the sealing plate, the limit strip sliding through the interior of the auxiliary plate.

[0011] In one possible design, an upper sliding plate is also slidably disposed inside the side shell, and the lower sliding plate and the upper sliding plate are fixedly connected by a connecting plate;

[0012] A limiting plate is slidably provided inside the side of the placement frame. One end of the limiting plate extends above the seedling tray, and the other end extends into the side shell. The side wall of the limiting plate is connected to the placement frame by a tension spring.

[0013] The upper sliding plate has a slot on its side wall, and the other end of the limiting plate engages with the slot.

[0014] The surface of the lower slide plate is also provided with a horizontal guide hole, which is connected to the oblique guide hole.

[0015] In one possible design, the connecting plate is connected to an operating mechanism, the operating mechanism including a handle fixed to the side wall of the connecting plate, the handle extending to the outside of the side shell.

[0016] In one possible design, the operating mechanism includes an electric push rod installed inside the side housing, with the telescopic end of the electric push rod fixedly connected to the connecting plate.

[0017] In one possible design, the placement frame and side shell are detachable separate structures.

[0018] In this application, during actual use, when the staff detects that the soil moisture has reached the specified range, the connecting plate is moved. The connecting plate will move the upper and lower sliding plates together. When the lower sliding plate moves, the guide rod will abut against the inside of the inclined guide hole, causing the sealing plate to move horizontally. The connecting hole and the drainage hole will then connect. At this time, excess water will drip into the water collection tray through the drainage hole and the connecting hole and be discharged through the drain hole. When it is necessary to remove the seedling tray, the upper sliding plate will continue to move through the connecting plate. When the slot moves to one side of the limiting plate, the limiting plate will be subjected to the force of the tension spring, causing it to move horizontally as well. One end of the limiting plate will be inserted into the slot, while the other end will be removed from the top of the seedling tray to release the limiting of the seedling tray, thus allowing it to be removed. At this time, the guide rod will enter the inside of the horizontal guide hole to cooperate with the movement.

[0019] When reassembling and resetting the seedling trays, simply move the connecting plate in the opposite direction. The guide rod will be restricted by the guide groove again, causing the sealing plate to reset. The inclined surface of the slot will press against the inclined surface of the limiting plate, thereby pushing the limiting plate to move so that its end is positioned above the seedling tray and repositioned.

[0020] In this utility model, the isolated anti-waterlogging seedling tray for flue-cured tobacco black shank disease controls drainage by coordinating the opening and closing of the sealing plate and the drainage hole. This allows for control of drainage based on whether the soil moisture level is within acceptable limits. Furthermore, the seedling tray is designed with an air gap to prevent water from flowing between the irrigation holes, thus achieving an isolation effect.

[0021] In this utility model, the isolated anti-immersion seedling tray for flue-cured tobacco black shank disease, through the loading and unloading structure, can achieve the following: when the upper sliding plate moves to a specific position, the end of the limiting plate disengages from the top of the seedling tray to unlock it; when resetting, the slot inclined surface squeezes the limiting plate to automatically reset and lock it.

[0022] In this invention, the state of its drainage holes can be controlled during use, thereby reducing the possibility of creating conditions for the reproduction of pathogens. At the same time, it can achieve isolated breeding, preventing the spread between them through soil and water, thereby improving the survival rate. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In one embodiment: Reference Figure 1-2 A seedling tray includes: a water receiving tray 1, a placement frame 4, a seedling tray 5, and a sealing plate 8.

[0032] The water receiving tray 1 and the placement frame 4 are fixedly connected by four support pillars 2. A drainage hole 10 is opened at the bottom of the water receiving tray 1 for connecting to external drainage pipes or other drainage equipment, or a drainage ditch can be set under the seedling tray.

[0033] The seedling tray 5 is installed in the placement frame 4 from above. Multiple planting troughs are arranged in a matrix on its surface. Seedlings are planted in the planting troughs of the seedling tray 5, and the soil thickness is less than the depth of the planting trough. Drainage holes 7 are opened at the bottom of each planting trough. Excess water in the soil is drained into the water collection tray 1 through the drainage holes 7. The sealing plate 8 is set below the seedling tray 5. The surface of the sealing plate has connecting holes 9 corresponding to the drainage holes 7. When the sealing plate 8 is in the initial position, its top surface is in contact with the bottom of the seedling tray 5, so that it blocks the drainage holes and reduces water loss. When the staff manually uses a humidity detector or other detection methods to detect that the soil moisture reaches the specified range, the sealing plate 8 is moved so that its connecting holes 9 are connected to the drainage holes 7 to drain water.

[0034] refer to Figure 3-4 The water receiving tray 1 is fixedly provided with a side shell 3 and an auxiliary plate 6 on both sides, and the sealing plate 8 is provided with a bracket on both sides. The bracket is slidably provided inside the side shell 3 and the auxiliary plate 6, so as to achieve lateral sliding.

[0035] The side shell 3 has a sliding lower slide plate 12 and an upper slide plate 11, which are fixedly connected by a connecting plate 16 for easy control. The surface of the lower slide plate 12 has an oblique guide hole 14 and a horizontal guide hole 13. The bracket extending from the sealing plate 8 into the side shell 3 is fixedly equipped with a guide rod 15, one end of which is embedded in the oblique guide hole 14. When the connecting plate 16 moves the lower slide plate 12, the guide rod 15 will be constrained by the guide groove, causing it to move the sealing plate 8 laterally, thereby connecting the connecting hole 9 with the drain hole 7.

[0036] A limiting plate 19 is slidably installed inside the side of the placement frame 4, with one end extending above the seedling tray 5. The side wall is connected to the placement frame 4 via a tension spring 18. The end of the limiting plate 19 engages with the slot 17 on the side wall of the upper slide plate 11. When the control connecting plate 16 moves the upper slide plate 11, the slot 17 will move to one side of the limiting plate 19 to provide clearance. At this time, the limiting plate 19 will move, causing one end to detach from the top of the seedling tray 5, thus releasing the limiting state.

[0037] Specifically, when the staff manually uses a humidity detector or other detection methods to detect that the soil moisture has reached the specified range, the connecting plate 16 is moved. The connecting plate 16 will move the upper sliding plate 11 and the lower sliding plate 12 together. When the lower sliding plate 12 moves, the guide rod 15 and the inclined guide hole 14 cooperate to drive the sealing plate 8 to move and connect the connecting hole 9 with the drainage hole 7. At this time, excess water drips into the water receiving tray 1 through the drainage hole 7 and the connecting hole 9 and is discharged through the drain hole 10.

[0038] When it is necessary to remove the seedling tray 5, the upper slide plate 11 will continue to move through the connecting plate 16. When the slot 17 moves to one side of the limiting plate 19, one end of the limiting plate 19 will disengage from the top of the seedling tray 5 to release the limiting of the seedling tray 5, so that it can be removed. At this time, the guide rod 15 will enter the interior of the horizontal guide hole 13 to cooperate in the movement.

[0039] When the seedling tray 5 is reassembled and reset, simply move the connecting plate 16 in the opposite direction. The guide rod 15 will be restricted by the guide groove again, causing the sealing plate 8 to reset. The inclined surface of the slot 17 will press against the inclined surface of the limiting plate 19, thereby pushing the limiting plate 19 to move so that its end is above the seedling tray 5 and is repositioned.

[0040] This application can be used in the field of agricultural planting equipment, or in other fields applicable to this application.

[0041] In another embodiment: Reference Figure 5 A flue-cured tobacco black shank isolation and anti-immersion seedling tray provides a control method for the movement of the connecting plate 16. It is applied to the field of agricultural planting equipment. The side wall of the connecting plate 16 is provided with a handle 20 extending to the outside of the side shell 3, so as to achieve manual control.

[0042] Or refer to Figure 6 An electric push rod 21 is installed inside the side shell 3, so that the end of its telescopic shaft is connected to the connecting plate 16 to realize remote control.

[0043] Both the placement frame 4 and the side shell 3 are detachable split structures, which facilitates the installation of internal components and subsequent maintenance, such as the replacement of the tension spring 18.

[0044] However, as is well known to those skilled in the art, the working principle and wiring method of the electric actuator 21 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
