[0030] Example

[0031] like Figure 1-Figure 3 As shown, the utility model provides a soilless cultivation planting tower, including a planting tower body 100, a liquid storage tank 200, a liquid supply pipe, a planting hole 110, a planting tube 400, a bracket 500 and a water receiving tray 600.

[0032] The planting tower body 100 is a three-dimensional structure with a thick bottom and a thin top. The material of the planting tower body 100 can be metal or plastic, preferably PVC plastic, which is corrosion-resistant, pollution-free, light and easy to install. The three-dimensional tower structure with a thick bottom and a thin top can avoid the problem of light blocking between the crops on the upper and lower layers, effectively increase the lighting effect, and thus solve the problems of low space utilization and poor crop lighting in existing soilless cultivation.

[0033] Furthermore, the structure of the planting tower body 100 can be a truncated cone or a prism structure, and its vertical section is a trapezoid, preferably a quadrangular cone, which has a simple structure and is easy to process. The quadrangular cone-shaped planting tower body 100 can be formed by integrally forming or splicing four trapezoidal boards.

[0034] On the side of the planting tower body 100, multiple layers of planting holes 110 are arranged, and each layer of planting holes 110 is arranged equidistantly, and each layer of planting holes 110 is arranged in a staggered manner to avoid affecting light and water flow. The planting holes 110 can be round holes, elliptical holes, etc., preferably upwardly inclined conical holes. The method for opening the conical holes is as follows: first use an angle grinder to open a long strip on the PVC board, and then use a hot air gun to heat around the cut. When the board becomes slightly soft, use a hole opener to expand and deform the cut to form a conical hole. The shape of the hole opener is preferably a half-sectioned bullet head shape cut along the axial direction.

[0035] The liquid storage tank 200 is arranged at the bottom of the planting tower body 100. The shape of the upper end surface of the liquid storage tank 200 is adapted to the shape of the bottom surface of the planting tower body 100. Any shape that can stably place the planting tower body 100 on the liquid storage tank 200 is acceptable. The liquid storage tank 200 arranged at the bottom of the tetrahedral planting tower body 100 is preferably a cubic structure with an upper opening. The liquid storage tank 200 is used to store nutrient solution or water. A water inlet pipe and a drain pipe are arranged at the bottom of the side of the liquid storage tank 200.

[0036] A liquid supply pipe and a water pump are arranged in the liquid storage tank 200. The liquid supply pipe is connected to the water pump. The liquid supply pipe is divided into a liquid supply main pipe 310 and a plurality of liquid supply branch pipes 320. The liquid supply main pipe 310 is arranged at the center of the liquid storage tank 200. The liquid supply main pipe 310 is placed vertically. The liquid supply branch pipes 320 are arranged at the bottom of the liquid supply main pipe 310. The liquid supply branch pipes 320 are perpendicular to the liquid supply main pipe 310 and are evenly distributed along the radial direction of the liquid supply main pipe 310. The liquid supply branch pipes 320 are used to irrigate the crops at the bottom of the planting tower. The top of the liquid supply main pipe 310 and the end of the liquid supply branch pipe 320 are both provided with nozzles 330. The height of the liquid supply main pipe 310 is slightly lower than the top surface height of the planting tower body 100. After turning on the water pump, the surrounding crops can be sprayed with the nozzles 330 on the liquid supply main pipe 310 and the liquid supply branch pipes 320. The nutrient solution is sprinkled through the liquid supply main pipe 310 and the liquid supply branch pipe 320, which can ensure that crops at different heights in the planting tower can obtain the required nutrient solution in a balanced manner.

[0037] Furthermore, the nozzle 330 is preferably an atomizing nozzle, which can disperse the liquid into tiny mist particles, which can better cover the surface of the crop. The atomized nutrient solution can dissolve more oxygen and contact with the plant roots more fully, thereby improving the spray effect.

[0038] Furthermore, the planting tower adopts intelligent control. An electrical box is arranged next to the planting tower. The electrical box includes a box body and a controller. The controller is electrically connected to the water pump to control the water supply time and frequency of the water pump.

[0039] Furthermore, a solenoid valve is provided on the water inlet pipe of the liquid storage tank 200, and a liquid level sensor is provided in the liquid storage tank. The liquid level sensor, the solenoid valve and the controller are electrically connected to cooperate in controlling the water inlet. When the liquid level of the liquid storage tank 200 is lower than the set height, the controller controls the solenoid valve on the water inlet pipe to open and automatically replenish water.

[0040] Furthermore, the planting tower is provided with a timer, which can set an appropriate time interval for starting the water pump to ensure that the roots of the plants are fully moistened while saving electricity.

[0041] Plants are planted in the planting holes 110, and the roots of the plants extend into the planting holes 110. A planting tube 400, a bracket 500, and a water tray 600 are provided on the inner wall of the planting tower body 100 at positions corresponding to the planting holes 110. The plant roots extending into the hole are placed in the planting tube 400 to prevent the plants from slipping and facilitate full contact between the plant roots and the liquid. The planting tube 400 is placed on the water tray 600, and the water tray 600 is fixed on the inner wall of the planting tower body 100 through the bracket 500. A plurality of drainage holes 410 are provided on the bottom wall of the planting tube 400. Excess water in the planting tube 400 will flow out through the drainage holes 410 and be stored in the water tray 600. The liquid overflowing from the water tray 600 will flow back into the liquid storage tank 200 for recycling. Air enters the planting tube 400 through the planting holes 110 to ensure that the plant roots have sufficient oxygen.

[0042] Furthermore, the planting tube 400 may be a cylindrical or rectangular structure, preferably adapted to the shape of the planting tower body, so that the planting tube 400 is close to the inner wall of the planting tower body 100, and the plant roots pass through the planting holes 110 and extend into the planting tube 400. The presence of the planting tube 400 makes it unnecessary to frequently open the water pump, which plays an energy-saving role.

[0043] Furthermore, the water receiving tray 600 may be a disk-shaped structure or a rectangular parallelepiped with flanges. The shape of the water receiving tray is preferably adapted to the shape of the inner wall of the planting tower. The height of the water receiving tray 600 is relatively low, and the height of the water receiving tray 600 is preferably 2-5 cm.

[0044] Further, rollers 700 are arranged at the four corners of the bottom of the liquid storage tank 200 to facilitate the movement of the planting tower. Preferably, the rollers 700 are provided with a brake function to ensure that the rollers can be firmly locked so that the planting tower can be stably stopped at any position.

[0045] Furthermore, a box cover 800 is provided on the top of the planting tower body 100 to prevent dirt from entering the liquid storage tank 200 and ensure the cleanliness of the nutrient solution in the liquid storage tank 200. The shape of the box cover 800 is adapted to the top surface shape of the planting tower body 100, thereby sealing the planting tower.

[0046] Furthermore, a humidity sensor is provided in the planting tower body 100 to detect the humidity value in the planting tower and send the humidity value to the controller. When the humidity value is less than the set humidity, the controller controls the water pump to turn on to increase the ambient humidity. When the humidity value reaches the set humidity, the controller controls the water pump to turn off. The water pump start time is set according to the actual water consumption required by the crop, and the excess water or nutrient solution flows back to the liquid storage tank 200 for reuse, with almost no waste. This irrigation method is more scientific and water-saving than the traditional sprinkler irrigation method.

[0047] Furthermore, the outer wall of the liquid storage tank 200 is set to black to avoid the formation of green algae.

[0048] Furthermore, the inner wall of the liquid storage tank 200 is set to black, creating an ecological dark environment that is conducive to the root system absorbing nutrients and allowing crops to grow better.

[0049] Furthermore, a lighting device is provided on the top of the planting tower, and the lighting device is preferably an LED plant growth lamp, which is an artificial light source that uses LED (light-emitting diode) as a light source to meet the lighting conditions required for plant photosynthesis. The spectrum can be customized according to the different cultivated crops. The main influence on plants is the visible light with a wavelength between 400-700nm. The light formula can be tailored for different plants according to the plant species to meet the light requirements of plants at different stages such as growth, flowering, and fruiting.

[0050] At night, it can provide light for the crops cultivated in the planting tower, so that the crops can also carry out photosynthesis at night, thereby promoting their growth.

[0051] Furthermore, a brightness sensor is arranged on the outer wall of the planting tower body 100, and the brightness sensor and the lighting device are connected to the controller. When the ambient brightness value is lower than the preset brightness value, the controller controls the lighting device to turn on to realize lighting, thereby promoting growth.

[0052] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. Various adjustments or changes may be made to the exemplary embodiments of the present invention specification without departing from the scope or spirit of the present invention. The scope of the claims should be based on the broadest interpretation to cover all modifications and equivalent structures and functions.
