Description

Technical Field

[0001] This application relates to the technical field of soilless cultivation, and particularly to a soilless cultivation box for rice. Background Art

[0002] Soilless cultivation is a new planting technique. In some areas without soil, such as deserts and beaches, the soilless cultivation technique can be used to grow crops, achieving the effect of maximizing the utilization of resources.

[0003] The current soilless cultivation techniques include hydroponics, aeroponics, and substrate cultivation. Among these cultivation techniques, aeroponics requires less water and has no requirements for solid substrates, so the overall resource consumption is less. Since the roots of plants are in a mixed environment of water and air during aeroponics, in order to simulate the dark environment in the soil, a plate-like structure for blocking light is usually installed on the cultivation box, such as the cross plate in CN216722542U. In the dark environment, the plant roots can grow normally, ensuring the good growth of the whole plant.

[0004] However, the above patent is for the soilless cultivation of potatoes. Since the vines of potatoes do not need to be upright, the vines can spread horizontally after extending from the cross plate. However, the rice plants need to be upright, and the height of the stem will gradually increase as the plant grows. The cross plate not only creates a dark environment for the roots but also provides support for the stem. However, the cross plate in the prior art cannot adjust its height as the plant grows taller, resulting in the low height of the cross plate being unable to meet the support requirements of the rice stem when the rice grows to a relatively large height, which may cause the rice to lodge. Summary of the Utility Model

[0005] The embodiments of this application provide a soilless cultivation box for rice to solve the problem in the prior art that the height of the cross plate cannot be adjusted, resulting in insufficient support for the stem of rice.

[0006] The embodiments of this application provide a soilless cultivation box for rice, including a box body, a cross plate, and a spray pump. A plurality of groups of support plates are arranged on the inner side surface of the box body. Each group of support plates includes support plates at the same height on two opposite inner side surfaces of the box body. The cross plate includes a fixed plate and a movable plate. The movable plate is rotatably connected to both ends of the fixed plate. The width of the fixed plate is less than the distance between the same group of support plates, and the sum of the widths of the fixed plate and the movable plates at both ends is greater than the distance between the same group of support plates but less than the width inside the box body.

[0007] In a possible implementation, the fixed plate and the movable plate are rotatably connected through a hinge, and the hinge is connected to the bottom surfaces of the fixed plate and the movable plate.

[0008] In a possible implementation, the fixed plate and the movable plate are integrally formed, and are connected by a flexible connecting portion located on the bottom surfaces of the fixed plate and the movable plate.

[0009] In a possible implementation, a handle is provided on the top surface of the fixed plate.

[0010] In a possible implementation, a plurality of support holes are provided on the fixed plate and the movable plate.

[0011] In a possible implementation, the spray pump is provided on the outer side surface of the box body, a spray pipe is provided inside the box body, the water outlet of the spray pump is connected to the spray pipe, and the water inlet of the spray pump is connected to a water supply pipe.

[0012] In a possible implementation, the spray pipe includes a main water pipe and branch water pipes. The main water pipe is connected to the water outlet of the spray pump. The number of the branch water pipes is multiple, the multiple branch water pipes are arranged in parallel, and each of the multiple branch water pipes is connected to the main water pipe.

[0013] In a possible implementation, a plurality of supporting plates are provided inside the box body. Each supporting plate is located directly below a support hole, and the branch water pipes are located above the side of the supporting plate.

[0014] The soil-less rice cultivation box in this application has the following advantages:

[0015] By setting the cross plate to a bendable structure and providing supporting plates with different heights on the inner side surface of the box body, the height of the cross plate can be adjusted as the rice grows, so that the cross plate can provide good support for the rice at any growth stage, avoiding lodging.

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a 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 of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] Figures 1-4 Schematic diagram of the structure of the soilless rice cultivation box provided by the embodiment of the present application. The embodiment of the present application provides a soilless rice cultivation box, including a box body 100, a cross plate 200 and a spray pump 300. A plurality of groups of support plates 101 are arranged on the inner side surface of the box body 100. Each group of support plates 101 includes support plates 101 at the same height on two opposite inner side surfaces of the box body 100 respectively. The cross plate 200 includes a fixed plate and a movable plate. The movable plate is rotatably connected to both ends of the fixed plate. The width of the fixed plate is less than the distance between the same group of support plates 101, and the sum of the widths of the fixed plate and the movable plates at both ends is greater than the distance between the same group of support plates 101, but less than the width inside the box body 100.

[0024] Exemplarily, the box body 100 in the embodiment of the present application is relatively long to support the cultivation requirements of a large number of rice plants. After the rice seedlings are raised, they are transplanted into the box body 100 of the embodiment of the present application. The roots of the rice seedlings are located inside the box body 100 and under the cross plate 200. In the initial stage of growth, the stems of the rice are still relatively short. At this time, the cross plate 200 can be placed on the support plate 101 at the lowest height. As the rice seedlings grow and the height of the stems gradually increases, the height of the rice stems can be measured regularly. If the increase in the stem height reaches a certain value, the cross plate 200 can be moved upward to a higher support plate 101 to adapt to the growth of the rice. As the rice grows taller and the cross plate 200 is gradually moved upward, the support position of the cross plate 200 on the rice stem can also gradually rise, so that the cross plate 200 can provide sufficient support for the rice at any growth stage, reducing or even avoiding the occurrence of rice lodging.

[0025] In an embodiment of the present application, a plurality of support holes 210 are provided on the fixed plate and the movable plate. The support holes 210 are preferably circular holes, and their diameters should not be too large or too small. The diameter of the support holes 210 should be slightly larger than the diameter of the rice stem during harvesting. If the diameter of the support holes 210 is too large, it is easy for external light to have an adverse effect on the roots below the cross plate 200. If the diameter of the support holes 210 is too small, it cannot meet the support requirements during all growth stages of the rice.

[0026] Specifically, although the fixed plate and the movable plate are rotatably connected, when both the fixed plate and the movable plate are in a horizontal position, the fixed plate and the movable plate can form a complete flat plate. The support holes 210 need to be distributed only on the fixed plate to avoid the situation where when the support holes 210 are provided on the movable plate, the movable plate is blocked by the rice stem when it rotates downward and cannot rotate.

[0027] Further, there are two ways of the connection structure between the fixed plate and the movable plate. In the first way, the fixed plate and the movable plate are rotatably connected by a hinge, and the hinge is connected to the bottom surfaces of the fixed plate and the movable plate.

[0028] Specifically, after using the hinge connection, since the connection position is on the bottom surfaces of the fixed plate and the movable plate, when the fixed plate is lifted, the movable plate can rotate downward to a vertical state. At this time, under the action of the hinge, the movable plate can rotate freely. And because the thickness of the movable plate is small, after the movable plate rotates to the vertical state, the width of the fixed plate and the sum of the thicknesses of the two movable plates are still smaller than the distance between the support plates 101 in the same group. Therefore, when the fixed plate is lifted upward, the fixed plate and the movable plate in the vertical state can be moved upward to a position above the higher support plate 101. When the fixed plate is put down, since the hinge allows the movable plate to be in a free state, in order to make the movable plate rotate to an inclined state so that a part of the movable plate is directly above the support plate 101, a pull rope can be connected to the top surface of each movable plate. When the fixed plate is lifted upward, the pull rope is in a slack state, enabling the movable plate to rotate to the vertical state. When the fixed plate is put down, the pull rope can be pulled upward to drive the movable plate upward, and then drive the movable plate to rotate to the inclined state. At this time, a part of each of the two movable plates is located directly above the support plate 101. Therefore, after the fixed plate is put down, the movable plate can be placed on the support plate 101. At the same time, since the connection position is on the bottom surfaces of the fixed plate and the movable plate, after the movable plate rotates upward to the horizontal state, the movable plate is blocked by the fixed plate and cannot continue to rotate upward, thereby making both the fixed plate and the movable plate in the horizontal state. The states of the cross plate 200 when it is lifted upward and after it is put down are respectively as Figure 2 shown by the solid line and the dotted line in

[0029] In the second way, the fixed plate and the movable plate are integrally formed, and the fixed plate and the movable plate are connected by a flexible connecting part, and the connecting part is located on the bottom surfaces of the fixed plate and the movable plate.

[0030] Specifically, when adopting the one-piece molding method, the fixed plate and the movable plate can be made of the same material, preferably plastic, and the connecting part is the plastic with a smaller thickness. Through this one-piece molding connection method, while the movable plate rotates, the connecting part maintains a certain elasticity. Under the action of this elasticity, when the fixed plate is lifted upward, the movable plate can rotate downward under its own weight and the action of the upper support plate 101 until the fixed plate and the bent movable plate can pass through the space between the support plates 101. And when passing through the space between the support plates 101, under the elastic action of the connecting part, the movable plate can rotate upward by a certain angle so that a part of the movable plate is located above the support plate 101. At this time, when the fixed plate is lowered, the movable plate can be placed on the support plate 101, and then the fixed plate and the movable plate form a complete cross plate 200 and are horizontally located above the support plate 101.

[0031] In a possible embodiment, a handle is provided on the top surface of the fixed plate.

[0032] Exemplarily, the handle can be of a fixed or movable structure, and an operator can lift the fixed plate through the handle, and then move the entire cross plate 200 upward.

[0033] After adopting the cooperation method of the cross plate 200 and the support plate 101 provided by the embodiment of the present application, when the cross plate 200 is moved upward, the main body of the cross plate 200, that is, the fixed plate, can move horizontally upward without being blocked by the rice leaves due to excessive height at one end of the fixed plate caused by inclination.

[0034] In a possible embodiment, the spray pump 300 is arranged on the outer side surface of the box body 100, a spray pipe is arranged inside the box body 100, the water outlet of the spray pump 300 is connected to the spray pipe, and the water inlet of the spray pump 300 is connected to the water supply pipe 310.

[0035] Exemplarily, the water supply pipe 310 is connected to a water storage tank, and the water storage tank stores a nutrient solution in which nutrients are dissolved. The nutrient solution is transported to the spray pump 300 through the water supply pipe 310. The spray pump 300 squeezes and transports the nutrient solution to the spray pipe, so that the nutrient solution is sprayed out through the nozzles on the spray pipe, and the sprayed mist-like nutrient solution drops onto the roots of the rice, providing the nutrients required for the growth of the rice.

[0036] In the embodiment of the present application, the spray pipe includes a main water pipe 400 and branch water pipes 410. The main water pipe 400 is connected to the water outlet of the spray pump 300. The number of the branch water pipes 410 is multiple, the multiple branch water pipes 410 are arranged in parallel, and the multiple branch water pipes 410 are all connected to the main water pipe 400.

[0037] Specifically, after the water pipe connected to the water outlet of the spray pump 300 is inserted into the box body 100 from the side of the box body 100, the water pipe is parallel to the width direction of the box body 100. Therefore, this water pipe will also be connected to the main water pipe 400 in the same direction. The branch water pipe 410 is parallel to the length direction of the box body 100. Therefore, after the flow direction of the nutrient solution in the main water pipe 400 changes by 90 degrees, it can flow into the branch water pipe 410 and finally be sprayed out from the nozzles on the branch water pipe 410. It should be understood that in order to ensure the stability of the main water pipe 400 and the branch water pipe 410, the main water pipe 400 and the branch water pipe 410 need to be fixed on the inner side surface of the box body 100. A protrusion with a structure similar to that of the support plate 101 can be used to place the main water pipe 400 and the branch water pipe 410 on this protrusion.

[0038] Furthermore, a plurality of support plates 500 are arranged inside the box body 100. Each support plate 500 is located directly below a support hole 210, and the branch water pipe 410 is located above the side of the support plate 500.

[0039] Specifically, the support plate 500 is used to support rice plants. The roots of the rice are located on the support plate 500, while the stems and leaves pass through the support holes 210 and are located outside the box body 100. A plurality of water permeable holes need to be arranged on the support plate 500 so that the excessive nutrient solution can drip to the inner bottom of the box body 100, and the nutrient solution accumulated at the inner bottom of the box body 100 can be discharged from the drain outlet (not shown in the figure). After the support plate 500 is arranged, the branch water pipe 410 is located between adjacent rows of support plates 500. And when there are support plates 500 on both sides of a branch water pipe 410, nozzles need to be arranged on both sides of the branch water pipe 410, and at least the nozzles arranged on the branch water pipe 410 need to correspond to each support plate 500 so that the rice roots on each support plate 500 can receive sufficient nutrient solution.

[0040] Although the preferred embodiments of the present application have been described, those skilled in the art can make additional changes and modifications to these embodiments once they learn the basic creative concepts. Therefore, the appended claims are intended to be interpreted to include the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application is also intended to include these modifications and variations.
