Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, and in particular to a seedling cultivation tray with an automatic watering function. Background Art

[0002] Agriculture is one of the key industries in society, which is related to people's daily diet, etc. In the process of development, many methods and ways have emerged to increase production and ensure the survival rate of seedlings. For example, targeted planting of seedlings is a typical one. The current method of targeted planting of seedlings is generally to use seedling trays in combination with human intervention in the planting environment. Therefore, seedling trays are one of the commonly used devices in this process.

[0003] When in use, the existing seedling trays generally do not have an automatic watering function, and some are watered manually. This method greatly increases the workload of the staff during the seedling raising process. Some of them have an automatic watering function, but they are generally completed by intelligent equipment in conjunction with a pipeline system, and the overall operating cost of this method is relatively high. At the same time, most of the current seedling trays are watered either only from the top or only from the bottom. Watering only from the top is not conducive to the root development of the seedlings because the roots of the plants will automatically extend to places with richer water systems. Watering only from the bottom makes it difficult for the seedlings to obtain sufficient water due to insufficient root development in the early stage. Summary of the invention

[0004] The purpose of the present invention is to provide a seedling tray with automatic watering function to solve the problems in the above background that watering the seedling tray consumes manpower or has high operating costs, is not conducive to the development of the seedling root system, or is difficult to obtain sufficient water in the early stage.

[0009] The connecting plate is provided with a hoisting mechanism for supporting the main body of the seedling tray;

[0010] The water storage seat is provided with an operating mechanism for adjusting the initial compression degree of the spring.

[0012] As a further solution of the present invention: the cross-sectional shape of the first water storage tank is trapezoidal, and the height inside the first water storage tank is the same as the height inside the second water storage tank.

[0013] As a further solution of the present invention: the adjustment mechanism includes a first threaded rod, the first threaded rod penetrates through a side of the water storage seat close to the second water storage tank, and a sealing piston is provided at one end of the first threaded rod close to the water storage seat.

[0014] As a further solution of the present invention: the first threaded rod is threadedly connected to the water storage seat, and the first threaded rod is rotationally connected to the sealing piston.

[0015] As a further solution of the present invention: handles are installed on both sides of the water storage tank, and rubber protective sleeves are installed on the outer walls of the handles. The water storage tank and the water storage seat are connected through a connecting pipe. Lamp mounting seats are evenly installed on the bottom of the water storage tank, and the lamp mounting seats and the drainage holes are horizontally staggered.

[0016] As a further solution of the present invention: a blocking block is arranged inside the drainage hole, connecting blocks are installed on both sides of the outer wall of the blocking block, and the connecting blocks are connected to the water storage tank.

[0017] As a further solution of the present invention: the lifting mechanism includes a winding roller, which is installed at the bottom of the connecting plate close to the water storage tank. A connecting rope is wound around the outside of the winding roller, a hook is installed at the bottom end of the connecting rope, and the hook is connected to the hanging ring.

[0018] As a further solution of the present invention: the operating mechanism includes a fixed plate, which is installed on a side of the water storage seat away from the second water storage tank, a second threaded rod passes through the bottom of the fixed plate, and a movable frame is provided at the top of the second threaded rod, connecting columns are installed at the four corners of the top of the movable frame, and the connecting columns are connected to the bottom end of the spring.

[0019] As a further solution of the present invention: the second threaded rod is threadedly connected to the fixed plate, and the second threaded rod is rotationally connected to the movable frame.

[0020] Beneficial effects of the present invention:

[0021] (1) The present invention provides a squeezing plate and a connecting plate on the water-retaining sponge block, and the connecting plate is connected to the main body of the seedling tray by a hoisting mechanism. Therefore, as the plant absorbs carbon dioxide and other substances to increase its weight, the squeezing plate can squeeze the water-retaining sponge block to implement automatic watering from top to bottom in the early stage, and the main body of the seedling tray is immersed in the water storage seat to achieve water replenishment from bottom to top in the later stage, thereby achieving automatic watering while meeting the water replenishment and development needs of the plant root system;

[0022] (2) The cross-sectional shape of the first water storage tank of the present invention is a trapezoid, so that when the main body of the seedling tray drops a unit height in the later stage of plant growth, the amount of water that can be absorbed in the first water storage tank will also increase, thereby meeting the increase in water required by the plant growth law;

[0023] (3) The present invention provides an adjustment mechanism for adjusting the internal capacity of the water storage seat on the water storage seat, provides an operating mechanism for adjusting the initial elastic force of the spring on the water storage seat, and connects the connecting plate to the main body of the seedling tray via a hoisting mechanism, thereby adjusting the water storage capacity in the water storage seat and the initial elasticity of the spring according to the initial weight and water demand of different plants, thereby ensuring that the subsequent descent rate of the plants matches the water supply;

[0024] (4) The present invention connects the water storage tank and the water storage seat through a connecting pipe, so that when adding water before use, water can be directly added to the water storage tank. When the water-retaining sponge block in the water storage tank absorbs full water, the excess water can enter the first water storage tank through the drainage hole and the connecting pipe, thereby making water addition more convenient and less likely to overflow.

[0025] (5) By arranging a blocking block and a connecting block in the drainage hole, when water is squeezed out by the water-retaining sponge block in the early stage, the water can fall through the annular gap between the blocking block and the inner wall of the drainage hole, thereby preventing the water from easily falling on the branches of the plant and affecting the watering effect.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] See also Figure 1-Figure 4 as well as Figure 5-Figure 8As shown, the present invention is a seedling tray with automatic watering function, including a water storage seat 1, a guide hole 5 is opened on the top of the water storage seat 1, and a first water storage tank 6 is reserved at the bottom of the guide hole 5, a second water storage tank 7 is opened on one side of the first water storage tank 6, a seedling tray body 8 is arranged inside the guide hole 5, and hanging rings 9 are installed at the four corners of the top of the seedling tray body 8. A hole is opened at the bottom of the seedling tray body 8, and the hole can also be opened at a position near the bottom of the side wall, so as to facilitate the absorption of water from below through the adsorption force of the soil and the water pressure;

[0039] A transparent window 2 is installed at one end of the water storage seat 1, and a scale line 3 is set at the end of the water storage seat 1 close to the transparent window 2, and support feet 4 are installed at the four corners of the bottom of the water storage seat 1, so that the staff can check the specific water level in the water storage seat 1 through the transparent window 2 and the scale line 3, and the scale line 3 is processed by engraving, and the support foot 4 can be replaced by a universal wheel with a parking part;

[0040] The cross-sectional shape of the first water storage tank 6 is a trapezoid, and the height inside the first water storage tank 6 is the same as the height inside the second water storage tank 7, so that when the seedling tray body 8 is in the early stage of plant growth, as the height decreases, it can absorb water from the first water storage tank 6 from below, and as the depth of the descent increases, the amount of water that can be absorbed by the subsequent descent of the same height will also increase, so it is more in line with the increase in the amount of water required for plant growth in the later stage;

[0041] The four corners of the top of the water storage seat 1 are all installed with mounting support columns 12, and the top of the mounting support columns 12 is installed with a water storage tank 13, the interior of the water storage tank 13 is provided with a water-retaining sponge block 16, the top of the water-retaining sponge block 16 is provided with an extrusion plate 17, and one end of the top of the extrusion plate 17 is reserved with a water-adding hole 18, the four corners of the top of the extrusion plate 17 are all installed with connecting plates 19, and the bottom of the connecting plate 19 is installed with a spring 20, the bottom of the water storage tank 13 is evenly opened with drainage holes 22, the bottom of the water storage tank 13 is evenly installed with lamp mounting seats 23, and the lamp mounting seats 23 and the drainage holes 22 are horizontally staggered;

[0042] When the water-retaining sponge block 16 is squeezed from above, the water in the water-retaining sponge block 16 can be squeezed through the drainage holes 22 and fall onto the seedling tray body 8, and the water falls more evenly, thereby achieving a more even top-down watering task in the early stage, which is convenient for the seedlings with insufficient root development to absorb;

[0043] The connecting plate 19 is provided with a hoisting mechanism for supporting the main body 8 of the seedling tray, and the hoisting mechanism includes a winding roller 26, which is installed at the bottom of the connecting plate 19 close to the water storage tank 13. A connecting rope 27 is wound around the outer side of the winding roller 26, and a hook 28 is installed at the bottom end of the connecting rope 27. The hook 28 is connected to the hanging ring 9, so that after the plant gains weight, the pressure can be transmitted to the squeezing plate 17 through the connecting rope 27, the winding roller 26 and the connecting plate 19, so that the squeezing plate 17 squeezes the water-retaining sponge block 16, thereby cooperating to complete the watering task from top to bottom;

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

[0045] And because the connecting rope 27 is wound on the winding roller 26, the staff can adjust the number of windings of each group of connecting ropes 27 on the winding roller 26 according to actual conditions during the hoisting process, so that the seedling tray body 8 can be hoisted at a specified height while the connecting plate 19 is kept in contact with the bottom of the water storage tank 13, thereby meeting more complex actual usage conditions, such as replacement of the model of the seedling tray body 8;

[0046] It should be noted that after the seedling tray body 8 is hoisted, as the plants grow and absorb carbon dioxide in the air and gain weight, the squeezing plate 17 begins to squeeze downward, and the water in the water-retaining sponge block 16 is squeezed out and falls into the seedling tray body 8, which further increases the weight of the seedling tray body 8. However, at this time, the plants do not absorb carbon dioxide and other substances in the air, so the seedling tray body 8 will drop slightly, but eventually stop at a certain level, and then as the plants grow and gain weight sufficiently, the squeezing plate 17 will be further driven to move down one end distance;

[0047] Repeat the above process, when the bottom of the seedling tray body 8 contacts the liquid surface in the guide hole 5, the soil in the seedling tray body 8 begins to absorb the water in the guide hole 5. Similarly, at this time, the seedling tray body 8 will drop slightly due to the absorbed water, but the water on the liquid surface is not completely absorbed, and sufficient carbon dioxide is not absorbed, so it eventually stops at a certain level, and then grows with the absorption of carbon dioxide, and the subsequent full absorption of the water on the liquid surface can continue to move downward, thereby ensuring the subsequent water supply;

[0048] At the same time, the protrusion at the bottom of the seedling tray body 8 can be longer than that of the existing similar devices, so that it is convenient to contact the liquid surface while the bottom part is used to absorb water. Moreover, since 8 is not completely immersed in water, the water pressure 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 without causing excessive water, thereby realizing bottom-up water supply to guide the development of plant roots in the later stage of plant growth;

[0049] Example 2

[0050] Based on the above embodiment 1, refer to Figure 1-Figure 2 As shown, the water storage seat 1 is provided with an adjustment mechanism for adjusting its own internal capacity, and the adjustment mechanism includes a first threaded rod 10, the first threaded rod 10 penetrates through a side of the water storage seat 1 close to the second water storage tank 7, and a sealing piston 11 is provided at one end of the first threaded rod 10 close to the water storage seat 1, the first threaded rod 10 is threadedly connected to the water storage seat 1, and the first threaded rod 10 and the sealing piston 11 are rotatably connected, so that the staff can drive the sealing piston 11 to move horizontally accordingly by rotating the first threaded rod 10, thereby changing the overall 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, and the operating mechanism includes a fixed plate 29, and the fixed plate 29 is installed on the side of the water storage seat 1 away from the second water storage tank 7. The bottom of the fixed plate 29 is penetrated by a second threaded rod 30, and the top of the second threaded rod 30 is provided with a movable frame 31, and connecting columns 32 are installed at the four corners of the top of the movable frame 31, and the connecting column 32 is connected to the bottom end of the spring 20, the second threaded rod 30 is threadedly connected to the fixed plate 29, and the second threaded rod 30 is rotatably connected to the movable frame 31, and then the spring 20 can be cooperated to realize auxiliary support for the connecting plate 19 and the extrusion plate 17, so as to avoid the deadweight of the seedling tray body 8 directly causing excessive extrusion of the water-retaining sponge block 16;

[0052] At the same time, the staff rotates the second threaded rod 30 to drive the movable frame 31 to move up and down accordingly, and in this process, the bottom of the connecting plate 19 always keeps in contact with the bottom of the water storage tank 13, so that the initial compression degree of the spring 20 can be changed, so that the gravity required for the subsequent descent of the seedling tray body 8 is different;

[0053] It should be noted that before hoisting the seedling tray body 8, the staff can hoist the seedling tray body 8 according to the subsequent needs by its own weight, and rotate the second threaded rod 30 so that when the seedling tray body 8 is hoisted, the connecting plate 19 remains in contact with the bottom of the water storage tank 13, so that the water-retaining sponge block 16 will not be squeezed in the initial state, and then the first threaded rod 10 is rotated according to the compression degree of the spring 20 at this time to adjust the sealing piston 11, so that the subsequent descending rate of the seedling tray body 8 under the compression state of the spring 20 matches the water obtained in the water storage seat 1 with the growth law of the plant.

[0054] Furthermore, when the plants or nutrients on the seedling tray body 8 are different and the initial deadweight is larger, the second threaded rod 30 can be further rotated on the basis of the above to change the initial compression degree of the spring 20, and the first threaded rod 10 can be rotated to change the internal capacity of the water storage seat 1. At this time, although the compression degree of the spring 20 is further increased, the unit descent degree is lower after the subsequent seedling tray body 8 increases in weight, but the water capacity of the water storage seat 1 at the same liquid level is further increased by the sealing piston 11. Therefore, the subsequent descent rate of the seedling tray body 8 and the water supply can still be ensured to match the cultivated plants through adjustment;

[0055] At the same time, corresponding scales can be set on the first threaded rod 10 and the spring 20, and the scales can be processed by brushing, so as to quantify the adjustment degree, and then the adjustment task can be completed before the seedling tray main body 8 is hoisted.

[0056] Example 3

[0057] Based on the above embodiment 1, refer to Figure 5 and Figure 8 As shown, handles 14 are installed on both sides of the water storage bin 13, and rubber protective sleeves 15 are installed on the outer walls of the handles 14. The water storage bin 13 is connected to the water storage seat 1 through a connecting pipe 21. The staff can lift, move or push the device through the handles 14 and the rubber protective sleeves 15. At the same time, when adding water before hoisting the seedling tray body 8, water can be added through the water adding holes 18 on the squeezing plate 17, and then the water retaining sponge block 16 starts to absorb water. After the water retaining sponge block 16 is fully absorbed, the excess water can fall into the water storage seat 1 through the drainage hole 22;

[0058] In the above process, when the water does not have time to fall from the drainage hole 22, it will further flow into the first water storage tank 6 through the connecting pipe 21, thereby preventing the phenomenon of water overflowing from the water storage tank 13;

[0059] An obstruction block 24 is provided inside the drainage hole 22, and connecting blocks 25 are installed on both sides of the outer wall of the obstruction block 24, and the connecting block 25 is connected to the water storage tank 13, so that when the squeezing plate 17 squeezes the water-retaining sponge block 16 and the water in the water-retaining sponge block 16 falls from the drainage hole 22 to the seedling tray main body 8, the obstruction block 24 can make each group of water falling from the drainage hole 22 fall downward in a manner close to the annular area, thereby avoiding the position on the corresponding seedling tray main body 8 where the seedlings are completely aligned, preventing the water from directly adhering to the seedlings and unable to reach the soil to be absorbed by the seedlings.

[0060] Working principle of the present invention: the device can be used in a designated greenhouse, the lamp is installed on the lamp mounting seat 23, and a designated amount of water is added to the water storage tank 13 through the water adding hole 18 according to the type of plant, and the water retaining sponge block 16 begins to absorb the water. When the water retaining sponge block 16 is fully absorbed, the subsequent water flows into the first water storage tank 6 through the drainage hole 22 and the connecting pipe 21, and then the second threaded rod 30 is rotated according to the initial weight of the seedling tray body 8 and the nutrients on the seedling tray body 8 and the plants to ensure that after the subsequent seedling tray body 8 is hoisted, The connecting plate 19 can still maintain the fit with the water storage tank 13, and the first threaded rod 10 can be 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 hoisted and the descending rate of the seedling tray body 8 driven by the growth matches the absorbable water amount in the water storage seat 1, and then the number of winding circles 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 hoisting, and the seedling tray body 8 can be hoisted through the cooperation of the hanging ring 9 and the corresponding hook 28;

[0061] The lamp mounting seat 23 is turned on, and then the plant begins to grow and gain weight by relying on the initial water and carbon dioxide in the nutrients. As the weight of the plant increases, the squeezing plate 17 begins to squeeze the water-retaining sponge block 16. The water in the water-retaining sponge block 16 falls to the surrounding of the plant in a nearly annular state through the gap between the blocking block 24 and the inner wall of the drainage hole 22, so as to facilitate the plant to absorb. After falling to a certain extent, the overall weight of the seedling tray main body 8 is insufficient because the plant has not absorbed enough carbon dioxide and other substances and stops falling. The above process is repeated until the bottom of the seedling tray main body 8 begins to contact the liquid surface in the water storage seat 1. At this time, although the water-retaining sponge block 16 can continue to be squeezed, the water contained in it begins to be obviously insufficient. The soil at the bottom of the seedling tray main body 8 can absorb the water it contacts, and through the adsorption effect of the soil and the water pressure, it is dredged upward, so that the middle layer of the soil always maintains sufficient moisture to provide water for the plant, and as the plant continues to grow and the weight continues to increase, the seedling tray main body 8 can continue to fall, so that the bottom of the seedling tray main body 8 can always provide sufficient water and will not completely exceed the required amount.

[0062] During the entire above process, not only can the automatic watering task be achieved, but the water supply can also be gradually increased. When the root system of the plant is not fully developed in the early stage of growth, watering can be carried out from top to bottom. In the later stage of plant growth, water can be supplied from bottom to top to guide the development of the plant root system. The effect of use on different types of plants can also be adjusted.

[0063] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
