[0002] Greenhouse hydroponics is a method of growing plants in a greenhouse environment using hydroponic technology. Greenhouse hydroponics combines the advantages of greenhouse cultivation and hydroponic technology to provide plants with a controllable growth environment. In a greenhouse, conditions such as temperature, humidity, and light can be effectively regulated to meet the needs of plants at different growth stages. Hydroponic technology replaces the traditional soil planting method by providing plants with liquid rich in minerals and nutrients, allowing plants to absorb nutrients more directly and efficiently.

[0003] The cultivation cycles of hydroponic plants in the greenhouse are different, and the absorption efficiency of nutrient solution is also different. In order to ensure that hydroponic plants can have sufficient water and nutrients during the growth process, it is necessary to ensure that the content of nutrient solution used for cultivation is not lower than the predetermined value. Artificial irrigation efficiency is slow, and the value of nutrient solution irrigation is difficult to grasp, so it is necessary to achieve the effect of automatic irrigation for plant cultivation in the greenhouse.

[0028] A guide groove 33 is provided on the water flow dividing plate 28 .

[0029] A laser transmitter 34 and a receiver 35 are respectively provided at both ends of the culture pool, and a float 36 is also provided in the culture pool. The receiver 35 is connected to the central controller 37 via a data cable. At the same time, the central controller 37 is connected to the motor driving the crawler 7 via an electric wire. The irrigation hollow plate 26 is connected to an external water pipe, and the water pipe is connected to the water tank.

[0030] In specific use, a variety of plants are cultivated in a greenhouse by hydroponics. Each plant has a different absorption rate of nutrient solution. When the nutrient solution of the cultivated plants is lower than the preset liquid level, the root system of the plant will extend downward, expand the root system to ensure that it can absorb more water. Plants with swollen root systems are more difficult to harvest and have a poor appearance. In order to ensure that the culture solution is maintained at a predetermined liquid level, the existing culture irrigation system is adjusted; when the liquid level in the culture tank drops, the height of the float 36 decreases, and the light signal emitted by the laser transmitter 34 is captured by the receiver 35. The receiver 35 converts the light signal into an electrical signal, which is transmitted to the central controller 37. The crawler 7 moves to move the equipment to the water-deficient culture tank, and the multi-axis connecting arm 10 adjusts the angle of the equipment. At the same time, the motor drives the bracket three 22 to rotate. Under the connection action of the short bracket two 21, the long bracket one 20 deflects, and under the coordinated action of the bracket four 23, the long bracket five 24 deflects, thereby causing the fastening connecting rod 25 to move. The multi-axis connecting arm 10 makes the pressing irrigation device 5 press on the edge of the culture pool, and the pressing contact plate 29 moves upward after being pressed. Under the limiting action of the limiting ring 32, the connecting rod 31 moves vertically upward, the upper connecting plate 30 moves upward, and drives the water flow dividing plate 28 to move upward. After the guide groove 33 in the middle of the water flow dividing plate 28 moves upward, the irrigation hollow plate 26 is connected, and the water flows through the irrigation hollow plate 26 into the culture pool; when the liquid level in the culture pool rises, the water level in the culture pool rises. After it reaches a high position, the float 36 rises accordingly, the light signal emitted by the laser transmitter 34 is blocked by the float 36, the electrical signal emitted by the receiver 35 is interrupted, the central controller 37 controls the motor connected to the bracket three 22 to reverse, and the multi-axis connecting arm 10 moves in the opposite direction to restore to the initial state; when the contact plate 29 is pressed to separate from the culture tank, the water flow dividing plate 28 moves vertically downward under the action of the spring on the connecting rod 31, and the guide groove 33 is hidden in the partition slide groove 27, thereby realizing the flow interruption work of the irrigation hollow plate 26.
