Description

Technical Field

[0001] The present application relates to the technical field of hydroponic equipment, and specifically discloses a hydroponic device for agricultural planting. Background Art

[0002] Hydroponic technology has a wide range of applications in agricultural planting and brings many advantages. For example, through hydroponics, vegetables can grow in a soilless environment, reducing the occurrence of soil diseases and pests, while improving the quality and yield of vegetables; hydroponics is also commonly used in the cultivation of flowers, such as roses, carnations, chrysanthemums, etc. Hydroponic flowers not only have a short growth cycle, but also have excellent quality and strong market competitiveness. Through hydroponics, flowers can better absorb nutrients, extend the flowering period, and improve the ornamental value; in addition to vegetables and flowers, hydroponics can also be used to grow other crops, such as rice, wheat and other food crops, as well as strawberries, grapes and other cash crops. These crops can achieve higher yields and better quality through hydroponics.

[0003] A hydroponic device is a device used to hydroponically grow crops in agricultural planting. For example, a hydroponic rack has multi-layered hydroponic boxes that can provide hydroponic space for multiple layers of crops in the vertical space, effectively improving the utilization rate of the vertical space, thereby hydroponically growing more crops, thereby increasing the yield and benefits of agricultural planting without increasing excessive site costs.

[0004] However, in the current hydroponic racks, each layer of the hydroponic box needs to be supplied with water separately, and the water level in the hydroponic box is controlled by valves, etc. As the number of layers of the hydroponic box increases, a large number of pipes need to be installed due to the installation of the water pipe positions, which increases the longitudinal installation space for the pipe installation, not only occupying the cultivation site, but also requiring the width of the hydroponic box to be increased, resulting in the crops in the center of the hydroponic box being unable to be illuminated by external light, that is, it is necessary to configure an additional lighting lamp on the top of the hydroponic box, further increasing the planting cost, and it is also inconvenient to take the crops in the center of the hydroponic box. Therefore, in view of this, the present invention provides a hydroponic device for agricultural planting to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that in a traditional hydroponic rack, each layer of the hydroponic box needs to be supplied with water separately, the pipeline installation space is large, the pipeline occupies the cultivation site and increases the planting cost.

[0006] In order to achieve the above-mentioned object, the basic scheme of the present invention provides an agricultural planting hydroponic device, comprising:

[0007] Frame;

[0008] A plurality of hydroponic boxes are vertically arranged on the frame in sequence;

[0009] A water supply assembly, comprising a water storage tank disposed on the top of the frame, a water supply main disposed at the bottom of the water storage tank, a plurality of water supply branches respectively connected to each hydroponic box, and a connecting pipe disposed between the water supply main and the water supply branches;

[0010] The regulating component includes a buoyancy member arranged in the regulating pipe, and sealing members respectively arranged at the top and bottom of the buoyancy member and capable of sealing the side wall of the water supply pipe. A water guide hole is arranged between the sealing members. When the water level in the hydroponic box reaches a threshold value, the sealing member arranged at the top of the buoyancy member seals the side wall of the water supply pipe.

[0011] The principles and effects of this basic solution are:

[0012] Compared with the prior art, the present invention supplies water to each hydroponic box by setting a water supply component, and utilizes the mutual cooperation of the buoyancy member and the sealing member in the regulating component. When the water level in one of the hydroponic boxes reaches the threshold, the sealing member seals the side wall of the water supply pipe, thereby preventing the nutrient solution and the like from continuing to enter the hydroponic box, so as to adjust the liquid level in each hydroponic box. In addition, due to the setting of the water guide holes, the liquid level adjustment and supply in each hydroponic box are independent of each other and do not interfere with each other, so that the liquid level of each hydroponic box can be independently adjusted with a smaller space and cost, and is not restricted by the increase in the number of layers of hydroponic boxes. This effectively solves the problem that in the traditional hydroponic rack, each layer of hydroponic boxes needs to be supplied with water separately, and the pipeline installation space is large, resulting in the pipeline occupying the cultivation site and increasing the planting cost.

[0013] Furthermore, the sealing member includes a top piston disposed on the top of the buoyancy member and capable of sealing the water supply pipe, and a bottom piston disposed on the bottom of the buoyancy member and capable of sealing the water supply pipe. When the water level in the hydroponic tank reaches a threshold value, the top piston seals the side wall of the water supply pipe disposed on the top of the connecting pipe. With this arrangement, the buoyancy member floats on the liquid surface to reflect the liquid level in the connecting pipe, that is, to reflect the liquid level in the hydroponic tank, so that when the liquid level increases, the top piston can seal the inner wall of the water supply pipe located at the upper part of the conversion pipe to block the water supply pipe from supplying water to the connecting pipe.

[0014] Furthermore, the water level in the water supply branch pipe is aligned with the set threshold water level in the hydroponic box, so as to avoid the liquid level difference between the water supply branch pipe and the hydroponic box affecting the adjustment of the liquid level in the hydroponic box.

[0015] Further, the buoyancy member comprises:

[0016] a buoyancy box, floating on the liquid surface in the connecting pipe;

[0017] A sliding piston, slidably connected in the buoyancy box;

[0018] A piston rod is slidably and sealingly connected to the buoyancy box and passes through the buoyancy box to be connected to the top piston;

[0019] The hydroponic device also includes an adjustment mechanism for adjusting the movement of the sliding piston.

[0020] With this arrangement, the position of the sliding piston is adjusted using an adjusting mechanism, thereby adjusting the distance between the top piston and the buoyancy box, and further adjusting the height of the buoyancy box when the top piston seals the inner wall of the water supply pipe, that is, the liquid level height of the conversion pipe and the hydroponic box, so as to adjust the water level in the hydroponic box to different heights according to the needs of different crop growth cycles.

[0021] Further, the sliding piston is slidably and sealingly connected to the inner wall of the buoyancy box, and the adjustment mechanism includes:

[0022] A regulating pipe, arranged on the outer wall of the connecting pipe;

[0023] The pneumatic piston is connected to the regulating tube with a sliding seal.

[0024] A driving member, which is arranged on the regulating tube and drives the pneumatic piston to move;

[0025] The air pipe is arranged between the regulating pipe and the buoyancy box.

[0026] With this arrangement, the position of the pneumatic piston is adjusted by a driving member, thereby adjusting the air pressure in the regulating tube and transmitting the air pressure to the buoyancy box through the air pipe, thereby using the air pressure to push the regulating piston to move and adjust the position of the sliding piston.

[0027] Furthermore, the sliding piston divides the buoyancy box into a first cavity and a second cavity which are independent of each other, the air pipe is connected to the first cavity, and a return spring is arranged in the second cavity. This method facilitates the use of air pressure to push the sliding piston to move so as to adjust the position of the sliding piston.

[0028] Furthermore, the driving member includes an adjusting rod threaded with the adjusting tube, one end of the adjusting rod is located outside the adjusting tube and is provided with a knob, and the other end of the adjusting rod extends into the adjusting tube and is rotatably connected with the pneumatic piston. In this way, by utilizing the threaded cooperation between the adjusting rod and the adjusting tube, when the adjusting rod rotates, it also generates relative movement with the adjusting tube, thereby driving the pneumatic piston to move.

[0029] Furthermore, the gas pressure piston and the regulating tube form a closed regulating chamber on a side away from the regulating rod, and the gas tube is connected to the regulating chamber, so that pressure changes are generated when the gas pressure piston moves, and the regulating piston is pushed to move by the action of gas pressure to adjust the position of the sliding piston.

[0030] Furthermore, a mounting seat is provided at the end of the regulating rod located in the regulating tube, the pneumatic piston is connected to the mounting seat, and baffles are provided on the mounting seat respectively located at the top and bottom of the pneumatic piston, so that the regulating rod drives the pneumatic piston to move vertically.

[0031] Based on the same inventive concept, the present invention provides a hydroponic method for agricultural planting, including using the above-mentioned hydroponic device to hydroponic crops, and supplying water to each hydroponic box through the above-mentioned water supply component during the hydroponic process and adjusting the water level in the hydroponic box through the above-mentioned regulating component. By setting the water supply component to supply water to each hydroponic box, and utilizing the mutual cooperation of the buoyancy member and the sealing member in the regulating component, when the water level in one of the hydroponic boxes reaches the threshold, the sealing member seals the side wall of the water supply main pipe, thereby preventing the nutrient solution and the like from continuing to enter the hydroponic box, and the liquid level in each hydroponic box can be adjusted. In addition, due to the setting of the water guide hole, the liquid level adjustment and supply in each hydroponic box are independent of each other and do not interfere with each other, so that the liquid level of each hydroponic box can be independently adjusted with a smaller space and cost, and is not limited by the increase in the number of hydroponic boxes, which effectively solves the problem that each layer of hydroponic boxes in the traditional hydroponic rack needs to be supplied with water separately, and the pipeline installation space is large, resulting in the pipeline occupying the cultivation site and increasing the planting cost.

[0039] The bracket is formed by welding multiple sections of channel steel together and fixed to the ground by rivets or the like. The top of the hydroponic box 2 is provided with a carrier plate 3 for placing hydroponic crops. A plurality of hydroponic holes 4 are symmetrically arranged on the carrier plate 3.

[0040] like Figure 1 and Figure 2 As shown, the water supply assembly includes a water storage tank 5 disposed on the top of the frame 1, a water supply main pipe 7 disposed at the bottom of the water storage tank 5, a plurality of water supply branch pipes 8 respectively connected to each hydroponic box 2, and a connecting pipe 9 disposed between the water supply main pipe 7 and the water supply branch pipe 8. The water storage tank 5 is also connected to several water inlet pipes 6, and valves and water pumps are arranged on the water inlet pipes 6 to supply water to the water storage tank 5.

The horizontal height in the water supply branch pipe 8 is level with the set threshold water level in the hydroponic box 2.

The water supply branch pipe 8 is arranged horizontally, and the bottom of the water supply branch pipe 8 is lower than the minimum liquid level required by the crop, and the top of the water supply branch pipe 8 is higher than the maximum liquid level required by the crop. Under this arrangement, the water levels of the hydroponic box 2, the water supply branch pipe 8 and the connecting pipe 9 are level with each other, and when the water level in one of the hydroponic boxes 2 reaches the threshold, the seal seals the side wall of the water supply main pipe 7 to prevent the nutrient solution from continuing to enter the hydroponic box 2, thereby realizing the adjustment of the liquid level in each hydroponic box 2.

[0042] In the process of the buoyancy member being raised and lowered by the liquid level, the bottom piston 19 is always sealedly connected to the top inner wall of the water supply main pipe 7 located at the bottom of the connecting pipe 9 .

[0043] The buoyancy member includes a buoyancy box 13 floating on the liquid surface in the connecting pipe 9, a sliding piston 14 slidingly and sealingly connected to the inner wall of the buoyancy box 13, and a piston rod 16 connected to the movable piston. The top of the piston rod 16 passes through the top of the buoyancy box 13 and is interconnected with the top piston 17. When the position of the sliding piston 14 changes, it drives the piston rod 16 and the top piston 17 to move, thereby adjusting the distance between the top piston 17 and the buoyancy box 13, and then adjusting the height of the position of the buoyancy box 13 when the top piston 17 seals the inner wall of the water supply main pipe 7, that is, the liquid level height of the conversion pipe and the hydroponic box 2, so as to adjust the water level in the hydroponic box 2 to different heights according to the needs of different crop growth cycles.

[0044] A water pipe 18 is provided between the top piston 17 and the top piston 17, which passes through the top piston 17, the piston rod 16, the sliding piston 14, the buoyancy box 13 and the bottom piston 19. A water guide hole is provided in the water pipe 18, so as to guide the water flow in the upper section of the water supply main pipe 7 into the lower section of the water supply main pipe 7, so as to facilitate water supply and liquid level adjustment for the water supply branch pipe 8 and the hydroponic box 2 below, and the liquid level adjustment and supply in each hydroponic box 2 are independent of each other and do not interfere with each other.

[0045] like Figure 3 As shown, an adjusting mechanism for adjusting the position of a sliding piston 14 is provided on the side wall of the connecting pipe 9, and the adjusting mechanism includes an adjusting pipe 10 installed to the outer wall of the connecting pipe 9 through a connecting plate 11, a pneumatic piston connected in a sliding seal in the adjusting pipe 10, a driving member for driving the pneumatic piston to move, and an air pipe 20 for ventilation, wherein the driving member includes an adjusting rod 12 threaded with the adjusting pipe 10, one end of the adjusting rod 12 is located outside the adjusting pipe 10 and is provided with a knob, the other end of the adjusting rod 12 extends into the adjusting pipe 10 and is rotatably connected to the pneumatic piston through a mounting seat 22, and baffles are provided on the mounting seat 22, which are respectively located at the top and bottom of the pneumatic piston, and the pneumatic piston and the side of the adjusting pipe 10 away from the adjusting rod 12 form a closed adjusting chamber, and the sliding piston 14 divides the buoyancy box 13 into a first cavity and a second cavity that are independent of each other, and the air pipe 20 is connected between the adjusting cavity and the first cavity, and a reset spring 15 is provided in the second cavity, and the air pipe 20 adopts a rubber tube with strong anti-deformation ability to avoid the air pipe 20 being squeezed and blocked by water pressure.

[0046] Based on the same inventive concept, this embodiment provides a hydroponic method for agricultural planting, including using the above-mentioned hydroponic device to hydroponically cultivate crops, and supplying water to each hydroponic box 2 through the above-mentioned water supply component during the hydroponic process; adjusting the water level in the hydroponic box 2 through the above-mentioned adjustment component; and adjusting the position of the sliding piston 14 through the above-mentioned adjustment mechanism to adjust the set liquid level height of the water level in each hydroponic box 2.

[0047] Compared with the prior art, the present embodiment supplies water to each hydroponic box 2 by setting a water supply component, and utilizes the mutual cooperation of the buoyancy member and the sealing member in the regulating component. When the water level in one of the hydroponic boxes 2 reaches the threshold, the sealing member seals the side wall of the water supply main pipe 7, thereby preventing the nutrient solution and the like from continuing to enter the hydroponic box 2, so as to adjust the liquid level in each hydroponic box 2. In addition, due to the setting of the water guide hole, the liquid level adjustment and supply in each hydroponic box 2 are independent of each other and do not interfere with each other, so that the liquid level of each hydroponic box 2 can be independently adjusted with a smaller space and cost, and is not restricted by the increase in the number of layers of the hydroponic box 2. This effectively solves the problem that in the traditional hydroponic rack, each layer of the hydroponic box 2 needs to be supplied with water separately, and the pipeline installation space is large, resulting in the pipeline occupying the cultivation site and increasing the planting cost.
