Description

Technical Field

[0001] This application relates to the technical field of seedling trays, and specifically relates to a rice seedling tray. Background Art

[0002] Rice is a major food crop for humans. The traditional rice seedling raising method is to soak the seeds until they start to germinate and then carry out field management for seedling raising. The field is moistened by rain, which easily causes the soil to become compacted, making it impossible for the germinated rice seedlings to grow vigorously. To save the amount of seeds used, reduce production costs, ensure uniform emergence of seedlings, and facilitate centralized management, most current rice seedling raising is carried out using seedling trays for hydroponic seedling raising.

[0003] Existing rice seedling trays are generally of an integral structure, with several seedling holes constructed on the tray body. Rice seedlings are cultivated in the seedling holes. After seedling raising is completed, the seedlings need to be removed from the seedling tray one by one. Currently, the removal method is to take them out from the top of the seedling tray. The soil easily adheres to the seedling grooves of the seedling tray, and there is no force application point for upward removal of the seedlings. When the soil adheres too tightly, it is necessary to apply force by holding the seedlings, that is, hold the seedlings and remove them from the seedling tray. At this time, it is easy to damage the seedlings. Therefore, this application proposes a rice seedling tray. Utility Model Content

[0004] The purpose of this application is to provide a rice seedling tray to solve the problem that when removing seedlings from the existing seedling tray, there is no force application point, and it is necessary to apply force by holding the seedlings, which is easy to damage the seedlings.

[0005] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0006] A rice seedling tray, comprising:

[0007] A top tray, at the bottom of which a plurality of cavity shells are connected in an array, the caliber of the cavity shells decreases sequentially from top to bottom and its bottom is an opening;

[0008] A bottom tray, detachably installed at the bottom of the top tray and sealing the bottom openings of a plurality of cavity shells. A plurality of sleeve shells are connected in an array on the bottom tray, and the plurality of sleeve shells are respectively inserted into the plurality of cavity shells, and a plurality of water seepage holes are penetratedly opened on the sleeve shells.

[0009] Further, connection bands are connected to the four corners of the top tray, and insertion holes are penetratedly opened on the connection bands. Plug connectors are arranged at the four corners of the bottom tray, and the four plug connectors are respectively in plug-in fit with the four insertion holes.

[0010] Further, the caliber of the sleeve shell gradually increases from top to bottom, and the water seepage holes are opened at the top of the sleeve shell.

[0011] Further, the height of the sleeve shell is one-third of the height of the cavity shell.

[0012] Furthermore, an insertion groove is formed at the bottom end of the cavity shell, and a sealing ring is arranged on the chassis. The sealing ring is inserted and matched with the insertion groove.

[0013] Furthermore, a groove is formed at the top of the top plate, and a plurality of overflow holes are formed through the inner wall of the groove. The plurality of overflow holes are respectively communicated with the plurality of cavity shells.

[0014] Furthermore, an extension plate is communicated with one side of the groove.

[0015] Furthermore, a plurality of support bars are arranged in an array at the bottom of the chassis.

[0016] The beneficial effects of the present application are as follows:

[0017] 1. In the present application, the seedling-raising tray is composed of a top plate and a chassis. The sleeve shell and the cavity shell form a complete seedling-raising cavity to raise rice seedlings. When the rice seedling raising is completed, the top plate is removed from the chassis. At this time, the cavity shell and the sleeve shell are separated, and the bottom of the seedling-raising cavity is directly exposed. When taking the seedlings, only need to reach out and apply force from the bottom of the cavity shell to the soil, and push the soil out upward from the cavity shell, then the seedlings can be taken out, so that the seedlings will not be damaged during the seedling-taking process, thus improving the practicability.

[0018] 2. In the present application, the diameter of the sleeve shell gradually increases from top to bottom, and the water seepage holes are formed at the top of the sleeve shell. When the sleeve shell and the cavity shell form a complete seedling-raising cavity, the bottom of the cavity is in a stepped shape, and the height of the water seepage holes is higher than the bottom of the cavity, which can not only discharge the excess water or nutrient solution to avoid excessive water accumulation affecting growth, but also intercept a part of the non-exceeding water to supply the normal growth and development of the seedlings, thus improving the practicability.

Detailed implementation manners

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0027] As Figures 1-6 shown, a rice seedling tray proposed in an embodiment of the present application includes:

[0028] A top plate 1, at the bottom of which a plurality of cell shells 2 are connected in an array. The caliber of the cell shells 2 decreases sequentially from top to bottom and the bottom thereof is open. Preferably, the cell shell 2 is configured as a conical square shell;

[0029] A bottom plate 3, detachably installed at the bottom of the top plate 1 and sealing the bottom openings of a plurality of cell shells 2. A plurality of sleeve shells 4 are connected in an array on the bottom plate 3. The plurality of sleeve shells 4 are respectively inserted into the plurality of cell shells 2. A plurality of water seepage holes 5 are formed through the sleeve shells 4. The sleeve shells 4 and the cell shells 2 form a complete seedling-growing cell. Soil is filled in the seedling-growing cell formed by the sleeve shells 4 and the cell shells 2, and seeds are scattered in the soil in the seedling-growing cell for seedling cultivation. Through the opened water seepage holes 5, excess water or nutrient solution is discharged. At the same time, the ventilation effect of the substrate (soil) is increased, and the cultivation effect on rice seedlings is improved. To make the solution more reasonable, preferably, the aperture of the water seepage hole 5 is 0.3 to 0.5 millimeters. When ensuring the functions of liquid drainage and ventilation, the soil in the seedling-growing cell will not be overly omitted;

[0030] When cultivating rice seedlings, first place the top plate 1 on the bottom plate 3, and make the plurality of sleeve shells 4 respectively inserted into the plurality of cell shells 2. The sleeve shells 4 and the cell shells 2 form a complete seedling-growing cell, and then fix the two to cultivate rice. When the rice seedling cultivation is completed, move the top plate 1 away from the bottom plate 3. At this time, the cell shells 2 and the sleeve shells 4 are separated, and the bottom of the seedling-growing cell is directly exposed. Since the soil will condense into soil blocks after being placed in the seedling-growing cell for a period of time for cultivation, when taking the seedlings, only need to reach into the bottom of the cell shell 2 and apply force to the soil to push the soil out upward from the cell shell 2, and then the seedlings can be taken out. In the process of taking seedlings, applying force to the soil from below will not damage the seedlings. The cell shell 2 is configured as a cone, and its caliber gradually decreases from top to bottom. Therefore, after the soil is pushed upward, even if the cell shell 2 has a certain depth, the subsequent soil will not excessively rub against the inner wall of the cell shell 2, making it convenient to take out the seedlings, thus improving the practicability.

[0031] As Figure 6As shown, in some embodiments, connection straps 6 are connected to the four corners of the top plate 1. Insertion holes 7 are formed through the connection straps 6. Plug connectors 8 are provided at the four corners of the bottom plate 3. The four plug connectors 8 are respectively inserted and matched with the four insertion holes 7. Preferably, the connection straps 6 are made of rubber material. A rubber ring is provided on the inner wall of the insertion hole 7. The plug connector 8 includes a plug post fixed on the bottom plate 3. A sphere is connected to the end of the plug post. The diameter of the sphere is greater than the inner diameter of the rubber ring. When connecting the top plate 1 and the bottom plate 3, the plug connector 8 is inserted through the insertion hole 7. By utilizing the deformable property of the rubber ring material and applying a certain force, the sphere can be inserted through the rubber ring, thus completing the connection. When disassembling, only a certain force needs to be applied to pull out the plug connector 8 from the insertion hole 7. The installation or removal is relatively simple and convenient.

[0032] As Figure 5 shown, in some embodiments, the diameter of the sleeve 4 gradually increases from top to bottom. The water seepage holes 5 are opened at the top of the sleeve 4. Preferably, the sleeve 4 is configured as a conical square shell, and the end with a larger bottom diameter is smaller than the end with a smaller bottom diameter of the sleeve 4. When the sleeve 4 is inserted into the hole shell 2, a rectangular partition cavity is formed between the sleeve 4 and the hole shell 2. The water seepage holes 5 are opened at the top of the sleeve 4, so that the height of the water seepage holes 5 is higher than the lowest end of the hole shell 2. This can not only drain the excess water or nutrient solution to avoid excessive water accumulation affecting growth, but also intercept a part (when the intercepted part meets the normal supply, it will not affect the seedling cultivation), thereby improving the practicability.

[0033] As Figure 5 shown, in some embodiments, the height of the sleeve 4 is one-third of the height of the hole shell 2. By setting the height of the sleeve 4 to be one-third of the height of the hole shell 2, when performing spray cultivation, the retained water can be controlled at most one-third. In this way, it can ensure that there is water at one-third of the bottom of the seedling cultivation hole at any time, which is beneficial to continuously supply the seedlings, thereby improving the practicability.

[0034] As Figure 5 shown, in some embodiments, an embedding groove 9 is opened at the bottom end of the hole shell 2. A sealing ring 10 is provided on the bottom plate 3. The sealing ring 10 is inserted and matched with the embedding groove 9. By opening the embedding groove 9 at the bottom of the hole shell 2 and providing the sealing ring 10 on the bottom plate 3, when the top plate 1 is placed on the bottom plate 3, under the gravity of the top plate 1, the soil and the seedlings, the sealing ring 10 is inserted into the embedding groove 9, which not only ensures the connection between the top plate 1 and the bottom plate 3, but also ensures that part of the water can be effectively intercepted at the bottom of the cultivation hole, ensuring the normal growth of the seedlings.

[0035] As Figure 1 and Figure 3As shown, in some embodiments, a groove 11 is formed at the top of the top plate 1. A number of overflow holes 12 are formed through the inner wall of the groove 11, and the number of overflow holes 12 are respectively connected to a number of cavity shells 2. Preferably, the groove 11 includes a number of connected first grooves and second grooves, and the first groove and the second groove are vertically connected to form a network groove. The number of cavity shells 2 are respectively located in the grid gaps of the network groove. When cultivating seedlings, nutrient solution will be added. Some nutrient solutions are not convenient to be directly sprayed on the seedling leaves by spraying. The drip irrigation method can be adopted to transport the nutrient solution into the groove 11. The nutrient solution flows along the groove 11 and then overflows into the cavity shell 2 through the overflow holes 12, so that the nutrient solution is applied to the soil and acts on the seedlings by overflowing, thereby improving the practicability.

[0036] As Figure 1 and Figure 3 shown, in some embodiments, an extension plate 13 is connected to one side of the groove 11. Through the connected extension plate 13, when cultivating and irrigating, water or nutrient solution is poured or dripped into the groove 11 through the extension plate 13, so that the water or nutrient solution will not spill to the outside when being poured, avoiding waste of water or nutrient solution.

[0037] As Figure 1 and Figure 4 shown, in some embodiments, a number of support bars 14 are arranged in an array at the bottom of the chassis 3. By arranging the support bars 14 at the bottom of the chassis 3, after the chassis 3 is placed on the ground or other placement racks, the bottom of the chassis 3 will not be in direct contact with the ground, will not block the sleeve 4, does not affect the normal discharge of excess water, and is also convenient for ventilation.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
