[0002] Agriculture is one of the key industries of society, which is related to people's daily diet, etc. In the development process, many methods and ways of increasing yield and ensuring seedling survival rate have emerged, for example, targeted planting of seedlings is a relatively typical one. When the seedlings are planted, the current method generally uses a seedling raising tray to cooperate with human intervention to plant the environment, so the seedling raising tray is one of the commonly used devices in the process.

[0003] The existing seedling raising tray generally does not have an automatic watering function when in use, and some use manual watering. This method greatly increases the workload of the staff in the seedling raising process.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] Embodiment one:

[0038] Please refer to Figures 1-4 and Figures 5-8As shown, the present application is a seedling tray with automatic watering function, including water storage seat 1, the top of water storage seat 1 is provided with guide hole 5, and the bottom of guide hole 5 is reserved with first water storage tank 6, one side of the inside of first water storage tank 6 is provided with second water storage tank 7, the inside of guide hole 5 is provided with seedling tray body 8, the four corner positions of the top of seedling tray body 8 are all installed with hanging ring 9, the bottom of seedling tray body 8 is provided with hole, the hole can also be provided at the position close to the bottom of the side wall, thereby facilitating the absorption of water from below through the adsorption of soil and water pressure;

[0039] One end of water storage seat 1 is installed with transparent window 2, one end of water storage seat 1 close to transparent window 2 is provided with scale line 3, and the four corner positions of the bottom of water storage seat 1 are all installed with supporting leg 4, facilitating the staff to check the specific water level height in water storage seat 1 through transparent window 2 and scale line 3, and scale line 3 is processed in the way of sunken engraving, and supporting leg 4 can be replaced with universal wheel with parking part;

[0040] The cross-sectional shape of first water storage tank 6 is trapezoidal, and the height inside first water storage tank 6 is the same as the height inside second water storage tank 7, so that when seedling tray body 8 is in the early stage of plant growth, water in first water storage tank 6 can be absorbed from below as the height decreases, and the deeper the depth of the decrease, the more water can be absorbed with the same height of subsequent decrease, so as to be more consistent with the increase of water required by plants in the later growth stage;

[0041] The four corner positions of the top of water storage seat 1 are all installed with installation supporting column 12, and the top of installation supporting column 12 is installed with water storage bin 13, the inside of water storage bin 13 is provided with water-retaining sponge block 16, the top of water-retaining sponge block 16 is provided with extrusion plate 17, one end of the top of extrusion plate 17 is reserved with water adding hole 18, the four corner positions of the top of extrusion plate 17 are all installed with connecting plate 19, the bottom of connecting plate 19 is installed with spring 20, the bottom of water storage bin 13 is uniformly provided with drainage hole 22, the bottom of water storage bin 13 is uniformly installed with lamp mounting seat 23, and lamp mounting seat 23 and drainage hole 22 are transversely staggered;

[0042] So that when water-retaining sponge block 16 is extruded from above, the water in water-retaining sponge block 16 can be extruded and dropped to seedling tray body 8 through drainage hole 22, and the falling is relatively uniform, thereby realizing the task of relatively uniform watering from top to bottom in the early stage, facilitating the absorption of seedlings with insufficient root development;

[0043] The connecting plate 19 is provided with a lifting mechanism for supporting the seedling tray body 8, which comprises a winding roller 26 installed at the bottom of the connecting plate 19 near the water storage compartment 13, and a connecting rope 27 wound outside the winding roller 26, and a hook 28 installed at the bottom end of the connecting rope 27, and the hook 28 is connected with the hanging ring 9, so that the plant can transmit the pressure to the pressing plate 17 through the connecting rope 27, the winding roller 26 and the connecting plate 19 after gaining weight, and then the pressing plate 17 can extrude the water-retaining sponge block 16, thereby completing the watering task from top to bottom;

[0044] After the above process, the water-retaining sponge block 16 can be further extruded after being extruded to a certain extent, but the remaining water is insufficient, but the bottom of the seedling tray body 8 has contacted with the water level in the water storage seat 1 and is supplied by the water in the water storage seat 1 at this time;

[0045] And since the connecting rope 27 is wound on the winding roller 26, the staff can adjust the number of winding turns of each group of connecting rope 27 on the winding roller 26 during lifting according to the actual situation, so that the seedling tray body 8 can be lifted at a specified height while the connecting plate 19 remains in contact with the bottom of the water storage compartment 13, thereby meeting more complex real use conditions, such as replacement of the seedling tray body 8 model, etc;

[0046] It should be noted that after the seedling tray body 8 is lifted, as the plant grows and gains weight by absorbing carbon dioxide and other substances in the air, the extrusion plate 17 begins to extrude downward, and the water in the water-retaining sponge block 16 is extruded out and falls into the seedling tray body 8, causing the weight of the seedling tray body 8 to further increase, but at this time the plant does not absorb carbon dioxide and other substances in the air, so the seedling tray body 8 will decrease slightly, but eventually stop at a certain extent, and then further downward movement of the extrusion plate 17 will be driven by the full weight gain of the plant;

[0047] The above process is repeated, and when the bottom of the seedling tray body 8 contacts with the liquid level in the guide hole 5, the soil in the seedling tray body 8 begins to absorb water in the guide hole 5, and for the same reason, the seedling tray body 8 will decrease slightly due to the absorption of water, but the water on the liquid surface is not completely absorbed, and not enough carbon dioxide is absorbed, so it will eventually stop at a certain extent, and then continue to move downward to ensure the supply of water in the subsequent process by absorbing carbon dioxide and fully absorbing the water on the liquid surface;

[0048] Meanwhile, the length of the protruding part at the bottom of the seedling tray main body 8 can be longer than that of the existing similar devices, so as to facilitate contact with the liquid surface, and the bottom part is used for adsorbing water. Since the seedling tray main body 8 is not completely immersed in water, the water pressure received is small, so the water content of the middle part is always lower than that of the bottom part, but it can meet the needs of plant growth and will not cause excessive water, thereby realizing self-watering from bottom to top to guide the development of plant root system in the later stage of plant growth;

[0049] Embodiment 2

[0050] Based on the above embodiment 1, referring to Figures 1-2 As shown in the figure, the water storage seat 1 is provided with an adjusting mechanism for adjusting the internal capacity thereof. The adjusting mechanism comprises a first threaded rod 10 which penetrates through one side of the water storage seat 1 close to the second water storage tank 7, and a sealing piston 11 is arranged at one end of the first threaded rod 10 close to the water storage seat 1. The first threaded rod 10 is in threaded connection with the water storage seat 1, and the first threaded rod 10 is in rotational connection with the sealing piston 11, so that the staff can drive the sealing piston 11 to move horizontally correspondingly by rotating the first threaded rod 10, thereby changing the total capacity in the water storage seat 1;

[0051] The water storage seat 1 is provided with an operating mechanism for adjusting the initial compression degree of the spring 20. The operating mechanism comprises a fixed plate 29 which is installed on one side of the water storage seat 1 away from the second water storage tank 7. A second threaded rod 30 penetrates through the bottom of the fixed plate 29, and an active frame 31 is arranged at the top end of the second threaded rod 30. Connection columns 32 are installed at the four corner positions of the top of the active frame 31, and the connection columns 32 are connected with the bottom end of the spring 20. The second threaded rod 30 is in threaded connection with the fixed plate 29, and the second threaded rod 30 is in rotational connection with the active frame 31, thereby assisting the support of the connecting plate 19 and the extrusion plate 17 in cooperation with the spring 20, avoiding that the weight of the seedling tray main body 8 directly causes excessive extrusion to the water-retaining sponge block 16;

[0052] Meanwhile, the staff can drive the active frame 31 to move up and down correspondingly by rotating the second threaded rod 30, and the bottom of the connecting plate 19 always keeps in contact with the bottom of the water storage bin 13 in this process, thereby changing the initial compression degree of the spring 20, so that the gravity required for the subsequent descent of the seedling tray main body 8 is different;

[0053] It should be noted that before lifting the seedling tray body 8, the staff can lift the seedling tray body 8 according to the subsequent needs of the self-weight, by rotating the second threaded rod 30 so that the connecting plate 19 keeps in contact with the bottom of the water storage bin 13 after the seedling tray body 8 is lifted, so that the water-retaining sponge block 16 is not initially extruded, and then the first threaded rod 10 is adjusted according to the compression degree of the spring 20 at this time, so that the subsequent seedling tray body 8 The water obtained in the water storage seat 1 at the compression state of the spring 20 matches the growth rule of the plant;

[0054] Further, when the plants or nutrients on the seedling tray body 8 are different so that the initial self-weight is larger, the second threaded rod 30 can be further rotated to change the initial compression degree of the spring 20 on the basis of the above, and the first threaded rod 10 is rotated to change the water capacity in the water storage seat 1, at this time, although the compression degree of the spring 20 is further increased, the subsequent seedling tray body 8 is increased in weight, and the unit decrease degree is lower, but the water capacity of the water storage seat 1 at the same liquid level is further increased by the sealing piston 11, so that the subsequent seedling tray body 8 The drop rate is still ensured to match the supplied water and the cultivated plant by adjusting;

[0055] Meanwhile, the first threaded rod 10 and the spring 20 can be provided with corresponding scales, which can be processed by brushing, so as to number the adjustment degree, and then the adjustment task can be completed before the seedling tray body 8 is lifted.

[0056] Embodiment 3

[0057] Based on the above embodiment 1, referring to Figure 5 and Figure 8 It is shown that the two sides of the water storage bin 13 are provided with handles 14, and the outer wall of the handle 14 is provided with a rubber protective sleeve 15, and the water storage bin 13 is communicated with the water storage seat 1 through the communication pipe 21, and the staff can lift and move or push the device through the handle 14 and the rubber protective sleeve 15, and when water is added before lifting the seedling tray body 8, the water can be added through the water adding hole 18 on the pressing plate 17, and then the water-retaining sponge block 16 starts to absorb water, and after the water-retaining sponge block 16 absorbs water, the excess water can fall into the water storage seat 1 through the drain hole 22;

[0058] When the water cannot fall from the drain hole 22 in the above process, it will further flow into the first water storage tank 6 through the communication pipe 21, so as to avoid the phenomenon that the water flows out from the water storage bin 13;

[0059] The inside of the drain hole 22 is provided with a blocking block 24, the two sides of the outer wall of the blocking block 24 are both provided with a connecting block 25, and the connecting block 25 is connected with the water storage bin 13, so that when the pressing plate 17 extrudes the water retaining sponge block 16, the water in the water retaining sponge block 16 falls from the drain hole 22 to the seedling tray body 8, and the blocking block 24 can make each group of water falling from the drain hole 22 fall in a nearly annular area, so as to avoid the position where the seedling tray body 8 is completely aligned with the seedling, and avoid the water directly adhering to the seedling and not reaching the soil to be absorbed by the seedling.

[0060] The working principle of the present application: the device can be used in a designated greenhouse, the lamp is installed on the lamp mounting seat 23, a specified amount of water is added to the water storage bin 13 through the water adding hole 18 according to the type of plant, the water retaining sponge block 16 starts to absorb water, when the water retaining sponge block 16 is full, the subsequent water flows into the inside of the first water storage tank 6 through the drain hole 22 and the connecting pipe 21, then the second threaded rod 30 is rotated according to the initial weight of the seedling tray body 8 and the seedling tray body 8 and the nutrient on the seedling tray body 8, to ensure that after the subsequent seedling tray body 8 is hung, the connecting plate 19 can still be attached to the water storage bin 13, and the first threaded rod 10 is rotated and adjusted according to the type of plant and the rotation amplitude of the second threaded rod 30 at this time, until the subsequent seedling tray body 8 is hung and the downward speed of the seedling tray body 8 driven by the growth matches the absorbable water amount in the water storage seat 1, then the winding number of the connecting rope 27 on the corresponding winding roller 26 is adjusted and determined, to ensure that the seedling tray body 8 can be at a specified height after being hung, and the seedling tray body 8 can be hung through the cooperation of the hanging ring 9 and the corresponding hook 28;

[0061] The lamp mounting seat 23 is opened, then the plant starts to grow and increase in weight by relying on the initial water and carbon dioxide in the nutrient, the pressing plate 17 starts to extrude the water retaining sponge block 16 as the plant increases in weight, the water in the water retaining sponge block 16 falls to the periphery of the plant in a nearly annular state through the gap between the blocking block 24 and the inner side wall of the drain hole 22, so as to facilitate the plant to absorb, after falling a certain amplitude, the overall weight of the seedling tray body 8 is insufficient to stop falling continuously because the plant does not absorb enough carbon dioxide and other substances, the above process is repeatedly performed until the bottom of the seedling tray body 8 starts to contact the liquid surface in the water storage seat 1, at this time, the water retaining sponge block 16 can be continuously extruded, but the contained water is obviously insufficient, the mud in the bottom of the seedling tray body 8 can absorb the contacted water, and the mud can be upwardly dredged through the absorption effect of the mud and the water pressure, so that the middle layer of the mud always maintains sufficient humidity to provide water for the plant, and the seedling tray body 8 can continue to fall as the plant continuously grows and increases in weight, so that the bottom of the seedling tray body 8 can always provide sufficient water and will not completely exceed the required amount;

[0062] In the whole above process, not only the automatic watering task can be realized, but also the water supply gradually increases, the watering from top to bottom when the root system of the plant in the early growth period is insufficient, the watering from bottom to top in the late growth period to guide the development of the root system of the plant, and the effect of using different kinds of plants is adjusted.

[0063] The above has carried out the detailed explanation to one embodiment of the application, but the content is only the preferred embodiment of the application, and cannot be considered to be used for limiting the implementation range of the application. Any equivalent change and improvement made according to the application scope of the application should still belong to the patent coverage range of the application.
