Abstract
Description
Technical Field
[0001] This utility model relates to the field of soilless crop cultivation technology, and in particular to a soilless cultivation device for uniform crop growth. Background Technology
[0002] Soilless cultivation refers to a cultivation method that uses water, peat moss, forest compost, vermiculite, or other media as a substrate to anchor the plant's roots, allowing the roots to directly contact the nutrient solution. In soilless cultivation, the composition of the nutrient solution is easily controlled and can be adjusted at any time. There are two main types of soilless cultivation: hydroponics and substrate culture. Hydroponics involves the plant roots directly contacting the nutrient solution without using a substrate. Substrate culture uses a solid substrate to anchor the plant roots, allowing them to absorb nutrients and oxygen through the substrate.
[0003] In existing technologies, water tanks are set up inside greenhouses, and seedlings are grown hydroponically within these tanks. Figure 1 As shown, the system includes a nutrient solution tank, a hydroponic solution tank, and seedling trays. The seedling trays are placed on the hydroponic solution within the hydroponic solution tank. During cultivation, the hydroponic solution from the nutrient solution tank is pumped to the first end of the hydroponic solution tank. The hydroponic solution at the first end slowly flows to the second end of the tank and then returns to the nutrient solution tank. During this flow, the hydroponic solution provides nutrients to the seedlings. However, as the hydroponic solution flows from the first end to the second end, the seedlings closer to the first end absorb nutrients first, causing the nutrient content in the solution flowing to the second end to gradually decrease. This results in insufficient nutrition for the seedlings growing closer to the second end, leading to uneven seedling growth. Consequently, seedlings on one side (the first end) grow excessively, while growth on the other side (the second end) is inhibited. Summary of the Invention
[0004] Based on this, the present invention provides a soilless cultivation device for uniform crop growth, in order to solve the technical problem in the prior art where seedlings near the first end of the hydroponic solution tank absorb the hydroponic solution first, while seedlings at the second end of the hydroponic solution tank do not have enough hydroponic solution, resulting in excessive growth of seedlings on one side (the first end) and inhibited growth of seedlings on the other side (the second end), thus causing uneven growth of seedlings.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A soilless cultivation device for uniform crop growth, comprising:
[0007] A seedling raising mechanism includes a hydroponic solution tank, a seedling tray, and a nutrient solution pipe. The hydroponic solution tank contains hydroponic solution, and the seedling tray is placed on the hydroponic solution in the hydroponic solution tank. A nutrient solution outlet is provided on one side of the hydroponic solution tank. The nutrient solution pipe is located inside the hydroponic solution tank, with one end of the nutrient solution pipe located on the side of the hydroponic solution tank where the nutrient solution outlet is located. The nutrient solution pipe extends in a direction away from the nutrient solution outlet, and a plurality of liquid outlets are provided on the nutrient solution pipe. The liquid outlets are inclined in a direction away from the nutrient solution outlet.
[0008] A nutrient solution tank is installed underground. The nutrient solution tank is connected to the nutrient solution pipe through an inlet pipe, and the nutrient solution tank is connected to the nutrient solution outlet through an outlet pipe.
[0009] Preferably, the nutrient solution tube is further provided with several branch tubes, which are inclined in the direction away from the nutrient solution outlet, and each branch tube is provided with several outlets on its periphery.
[0010] Preferably, each of the branch pipes is also provided with a liquid outlet at its end.
[0011] Preferably, a water pump is provided on the inlet pipe, and the water pump is used to pump the hydroponic solution in the nutrient solution tank into the nutrient solution pipe through the inlet pipe.
[0012] Preferably, the hydroponic solution tank is provided with a water storage film, which is used to hold the hydroponic solution.
[0013] Preferably, the water storage membrane is a plastic membrane.
[0014] Preferably, a fixing member is provided above the side wall of the hydroponic liquid tank, and the fixing member is used to fix the water storage film.
[0015] Preferably, it also includes a partition plate, which is disposed on the hydroponic liquid tank. The lower surface of the partition plate is provided with a plurality of legs, which are distributed in the middle area of the lower surface of the partition plate. The plurality of legs are supported on the inner bottom of the hydroponic liquid tank, and the plurality of legs are detachably connected to the hydroponic liquid tank.
[0016] Preferably, it further includes a heat insulation layer, which is disposed on the lower surface and peripheral surface of the hydroponic solution tank, and the heat insulation layer is used to insulate the hydroponic solution tank.
[0017] Preferably, a support frame is also provided below the insulation layer, which is used to increase the distance between the ground and the insulation layer.
[0018] Compared with the prior art, the present invention has at least the following advantages:
[0019] This utility model provides a soilless cultivation device for uniform crop growth, comprising a hydroponic solution tank, a seedling tray, nutrient solution pipes, and a nutrient solution tank. The seedling tray is placed on the hydroponic solution in the hydroponic solution tank. The hydroponic solution in the nutrient solution tank is pumped into the nutrient solution pipe through the inlet pipe, and the hydroponic solution is pumped into the hydroponic solution tank through the outlet of the nutrient solution pipe. Because the outlet is tilted away from the nutrient solution outlet, the hydroponic solution in the hydroponic solution tank gradually flows towards the nutrient solution outlet. At this time, the hydroponic solution entering the hydroponic solution tank through the outlet mixes with the water flowing from the hydroponic solution tank towards the nutrient solution outlet. The cross-flow of the nutrient solution allows the two to impact each other, stirring the hydroponic solution in the hydroponic tank. In other words, the hydroponic solution entering the tank through the outlet flows against the flow of the nutrient solution flowing towards the outlet. This stirring keeps the hydroponic solution in the tank constantly mixed, resulting in a uniform distribution of nutrients throughout the tank. This prevents seedlings from growing excessively on one side while inhibiting growth on the other, ensuring that the seedlings grow evenly as they absorb nutrients. Attached Figure Description

Detailed Implementation
[0027] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0028] Please refer to Figures 2 to 6 A soilless cultivation device for uniform crop growth, comprising:
[0029] A seedling raising mechanism includes a hydroponic solution tank 100, a seedling tray 110, and a nutrient solution pipe 120. The hydroponic solution tank 100 contains hydroponic solution, and the seedling tray 110 is placed on the hydroponic solution in the hydroponic solution tank 100. A nutrient solution outlet 131 is provided on one side of the hydroponic solution tank 100. The nutrient solution pipe 120 is located inside the hydroponic solution tank 100, with one end of the nutrient solution pipe 120 located on the side of the hydroponic solution tank 100 where the nutrient solution outlet 131 is located. The nutrient solution pipe 120 extends away from the nutrient solution outlet 131, and has several outlets on the nutrient solution pipe 120. The outlets are inclined away from the nutrient solution outlet 131.
[0030] The nutrient solution tank 200 is installed underground. The nutrient solution tank 200 is connected to the nutrient solution pipe 120 through the inlet pipe 140, and the nutrient solution tank 200 is connected to the nutrient solution outlet 131 through the outlet pipe 150.
[0031] Specifically, this application provides a soilless cultivation device for uniform crop growth, including a hydroponic solution tank 100, a seedling tray 110, a nutrient solution pipe 120, and a nutrient solution tank 200. The seedling tray 110 is placed on the hydroponic solution in the hydroponic solution tank 100. The hydroponic solution in the nutrient solution tank 200 is pumped into the nutrient solution pipe 120 through the inlet pipe 140. The nutrient solution pipe 120 is placed inside the hydroponic solution tank 100. The hydroponic solution is pumped into the hydroponic solution tank 100 through the outlet of the nutrient solution pipe 120. The hydroponic solution in the nutrient solution tank 200 flows away from the nutrient solution outlet 131, realizing the circulation of the hydroponic solution in the nutrient solution tank within the hydroponic solution tank 100. During this process, because the outlet is tilted away from the nutrient solution outlet 131, the hydroponic solution in the hydroponic solution tank 100 gradually flows towards the nutrient solution outlet 131. At this time, the hydroponic solution entering the hydroponic solution tank 100 through the outlet and the hydroponic solution flowing towards the nutrient solution outlet 131 in opposite directions cause them to impact each other, thus agitating the hydroponic solution in the hydroponic solution tank 100. In other words, the hydroponic solution entering through the outlet... The hydroponic solution in tank 100 flows counter-currently to the nutrient solution outlet 131. This agitates the hydroponic solution in tank 100, ensuring continuous mixing and even distribution of nutrients throughout the tank. This prevents excessive growth of seedlings on one side of the tank while inhibiting growth on the other, resulting in uniform growth of seedlings in the tank.
[0032] In a preferred embodiment, the nutrient solution pipe 120 is further provided with a plurality of branch pipes 130, the plurality of branch pipes 130 being inclined in a direction away from the nutrient solution outlet 131, each branch pipe 130 having a plurality of outlets on its periphery, and each branch pipe 130 also having an outlet at its end.
[0033] Specifically, several branch pipes 130 are inclined on the nutrient solution pipe 120 in a direction away from the nutrient solution outlet 131. Several liquid outlets are provided on the periphery and end of the branch pipes 130. Since the liquid outlets are located at various positions in the hydroponic solution tank 100, there are many stirring points in the hydroponic solution tank 100, resulting in good effect. The liquid outlets spray the hydroponic solution crosswise in the hydroponic solution tank 100, which effectively stirs all positions in the hydroponic solution tank 100, so that the seedlings grow evenly in the process of absorbing nutrients.
[0034] In a preferred embodiment, a water pump 141 is provided on the inlet pipe 140, and the water pump 141 is used to pump the hydroponic solution in the nutrient solution tank 200 into the nutrient solution pipe 120 through the inlet pipe 140.
[0035] Specifically, a water pump 141 is installed on the inlet pipe 140 to pump the hydroponic solution in the nutrient solution tank 200 into the water pump 141. After the water pump 141 is started, under the action of centrifugal force generated by the high-speed rotation of the impeller, the solution is pumped into the nutrient solution pipe 120 through the inlet pipe 140. The hydroponic solution is then transported to the hydroponic solution tank 100 through the nutrient solution pipe 120 to add hydroponic solution to the hydroponic solution tank 100, providing nutrition for the seedlings.
[0036] In a preferred embodiment, a water storage film is provided inside the hydroponic solution tank 100. The water storage film is a plastic film and is used to hold the hydroponic solution.
[0037] Specifically, a water storage membrane is provided inside the hydroponic solution tank 100. The water storage membrane can be a waterproof cloth membrane, a polyethylene geomembrane, or a plastic film. Preferably, in this application, the water storage membrane is a transparent water storage membrane. A large water storage membrane is placed on the opening of the hydroponic solution tank 100 and stretched down. The inner side of the water storage membrane is in contact with the inner bottom of the hydroponic solution tank 100. At the same time, the portion of the water storage membrane that extends beyond the opening of the hydroponic solution tank 100 is bent to the outer wall of the hydroponic solution tank 100 and fixed by the fastener 160. The water storage membrane has good waterproof performance and can prevent water penetration. Placing the water storage membrane inside the hydroponic solution tank 100 creates a water storage area inside the water storage membrane, providing nutrition to the seedlings and supplementing the seedlings with nutrients.
[0038] In a preferred embodiment, a fixing member 160 is provided on the side wall of the hydroponic liquid tank 100, the fixing member 160 being used to fix the water storage film.
[0039] Specifically, the fixing element 160 can be a hook, buckle, cloth strip, clip, etc. Preferably, in this application, the fixing element 160 is a clip. The fixing element 160 is set above the side wall of the hydroponic liquid tank 100. The part of the water storage film that exceeds the opening of the hydroponic liquid tank 100 is bent to the outer side wall of the hydroponic liquid tank 100 by the fixing element 160 and fixed to the side wall of the hydroponic liquid tank 100 by the fixing element 160. It is aesthetically pleasing and facilitates the setting of the water storage film. For example, during the setting process, if the setting is not proper and there is not enough space in a certain place, the water storage film will not be able to be laid in the hydroponic liquid tank 100 at that place. The fixing element 160 can fix it and avoid this situation.
[0040] In a preferred embodiment, the system further includes an isolation plate 170, which is disposed on the hydroponic liquid tank 100. The lower surface of the isolation plate 170 is provided with a plurality of legs 171, which are distributed in the middle area of the lower surface of the isolation plate 170. The plurality of legs 171 are supported on the inner bottom of the hydroponic liquid tank 100, and the plurality of legs 171 are detachably connected to the hydroponic liquid tank 100.
[0041] Specifically, the isolation plate 170 is a grid, the seedling tray 110 is set on the isolation plate 170, and several roots of the seedling can be set opposite to the isolation plate 170, with one root corresponding to one grid on the isolation plate 170, and are introduced into the hydroponic solution for nutrient absorption. Several legs 171 are distributed and arranged in the middle area of the lower surface of the isolation plate 170. The legs 171 can be steel pipes, wooden sticks, iron rods, etc. Preferably, in this application, the legs 171 are wooden sticks. The legs 171 support the inner bottom of the hydroponic liquid tank 100. The height of the legs 171 is higher than the liquid level of the hydroponic liquid in the hydroponic liquid tank 100. The legs 171 are distributed in the central area of the lower surface of the isolation plate 170 and supported in the inner bottom of the hydroponic liquid tank 100. The legs 171 can be detachably connected to the hydroponic liquid tank 100 for easy removal. By setting several legs 171, the isolation plate 170 can be prevented from bending under excessive load, thus providing support for the isolation plate 170.
[0042] Preferably, it further includes a heat insulation layer 180, which is disposed below the hydroponic liquid tank 100 and is used to insulate the hydroponic liquid tank 100.
[0043] Specifically, the insulation layer 180 can be a perlite insulation layer, polyurethane foam, or a polyurethane insulation layer. Preferably, in this application, the insulation layer 180 is a polyurethane insulation layer. The insulation layer 180 has moisture-proof and waterproof properties, as well as a low thermal conductivity and good thermal performance.
[0044] During cultivation, because the greenhouse is a closed space exposed to direct sunlight, the temperature inside the greenhouse gradually rises, as does the ground surface temperature. For example, with all car windows closed, the interior temperature increases rapidly under direct sunlight. Similarly, as the greenhouse and ground temperatures rise, the temperature of the hydroponic solution in the hydroponic solution tank 100 also increases. Excessively high temperatures in the hydroponic solution tank 100 can, in severe cases, burn the seedlings, resulting in waste. Therefore, a heat insulation layer 180 is installed on the lower and surrounding surfaces of the hydroponic solution tank 100. This heat insulation layer 180 consists of several heat insulation panels, and adjacent panels can be detachably connected for easy placement and replacement. Several heat insulation boards are spliced together and attached to the lower and surrounding surfaces of the hydroponic solution tank 100. The hydroponic solution tank 100 is insulated by the heat insulation layer 180. Due to the excellent heat insulation performance of the heat insulation layer 180, as the temperature of the greenhouse increases, it can block the heat radiation from the ground and the heat inside the greenhouse. This prevents the temperature of the hydroponic solution in the hydroponic solution tank 100 from rising with the temperature of the greenhouse, which is beneficial to the growth of seedlings, avoids the seedlings being burned, and improves the survival rate of the seedlings.
[0045] In a preferred embodiment, a support frame 181 is further provided below the insulation layer 180, the support frame 181 being used to increase the distance between the ground and the insulation layer 180.
[0046] Specifically, the support frame 181 can be an iron frame, a wooden frame, or a stone block, etc. Preferably, in this application, the support frame 181 is a stone block. Since the greenhouse is a closed space and is exposed to direct sunlight, the temperature inside the greenhouse will increase, and the ground surface temperature will also rise. By setting the support frame 181 below the insulation layer 180, the distance between the insulation layer 180 and the ground is increased through the support frame 181. This increases the heat radiation distance from the ground to the insulation mechanism, thereby reducing the heat radiation intensity from the ground to the hydroponic solution tank 100, and further preventing the temperature of the hydroponic solution in the hydroponic solution tank 100 from rising due to heat radiation from the ground.
[0047] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
