[0022] The cultivation tube 2 is provided with upward opening holes at intervals, and the planting frame 201 is a cup-shaped structure, with a hollow groove at the lower end and the upper edge stuck in the opening hole.

[0023] The preferred scheme also includes a support frame 1, the support frame 1 is provided with a slope frame 101, a plurality of cultivation tubes 2 are provided on the slope frame 101, each cultivation tube 2 is connected end to end, the overflow main pipe 4 in each cultivation tube 2 is connected end to end, and a liquid pump 8 is provided at the bottom of the junction box 3, and the liquid pump 8 is connected to the inside of the cultivation tube 2 at the highest position.

[0024] One end of the overflow main pipe 4 in the highest cultivation tube 2 on the slope frame 101 is blocked, and the other end is connected to one end of the overflow main pipe 4 in the cultivation tube 2 of the next layer, and so on until it is connected to the overflow main pipe 4 in the cultivation tube 2 of the lowest layer. The end of the overflow main pipe 4 in the cultivation tube 2 of the lowest layer is connected to the junction box 3.

[0025] In a preferred embodiment, the culture tube 2 includes a hollow tube body 202 , and detachable end caps 203 are provided at both ends of the hollow tube body 202 . The end caps 203 are provided with overflow pipe passage holes 209 , and the overflow main pipe 4 passes through the overflow pipe passage holes 209 .

[0026] The overflow main pipe 4 and the overflow branch pipe 401 can be made of hard pipes. The funnel structure 403 is installed on the overflow branch pipe 401. The funnel structure 403 can be threadedly connected to the overflow branch pipe 401. After adjusting the height of the high funnel structure 403, the whole is inserted from the port of the hollow tube body 202. One end of the overflow main pipe 4 passes through the overflow pipe through hole 209 of the end cover 203, and the end cover 203 is buckled on the hollow tube body 202. Then, the other end of the overflow main pipe 4 is inserted into the overflow pipe through hole 209 of the other end cover 203, and the end cover 203 is buckled to close the culture tube 2.

[0027] A sealing rubber ring is provided at the overflow pipe through hole 209 .

[0028] In the preferred embodiment, the end cover 203 is provided with a through hole 205 eccentrically arranged relative to the circular end surface of the end cover 203, a rotatable circular baffle 208 is provided on the outer side of the through hole 205, and a nutrient solution inlet and outlet 204 eccentrically arranged relative to the circular baffle 208 is provided on the circular baffle 208. The end cover 203 is also provided with a pressure ring 206, which presses the circular baffle 208.

[0029] Since the sealing ring 207 is generally made of rubber, it generates a certain friction force on the outer wall of the circular baffle 208, so that the circular baffle 208 has a certain resistance when rotating, so that the nutrient solution inlet and outlet 204 can maintain this position after rotating.

[0030] A sealing ring 207 is provided on the outer edge of the circular baffle 208. The circular baffle 208 is stuck between the end cover 203 and the through hole 205 and rotates. Since the nutrient solution inlet and outlet 204 is eccentric, the circular baffle 208 can be rotated to adjust the height of the nutrient solution inlet and outlet 204 relative to the bottom end of the planting frame 201, thereby adjusting the height of the flowing liquid level. The nutrient solution enters from the nutrient solution inlet and outlet 204 at one end of the highest cultivation tube 2. Since the cultivation tubes 2 are connected in series, the final liquid outlet is the nutrient solution inlet and outlet 204 at one end of the lowest cultivation tube 2. The height adjustment function of each nutrient solution inlet and outlet 204, in conjunction with the height adjustment function of the funnel structure 403, can effectively adjust the dynamic liquid level of the nutrient solution flowing in the cultivation tubes 2 of each height layer to be consistent.

[0031] In a preferred solution, a sealing ring 7 is provided on the inner side of the end cover 203 , the sealing ring 7 is sleeved with the outer wall of the hollow tube body 202 , and a hoop 6 is sleeved on the outer side of the end cover 203 .

[0032] The end cover 203 is clamped by the hoop 6 and the joint is sealed by the sealing ring 7.

[0033] In the preferred embodiment, a pipe clamp 5 is further provided, which includes an arc groove portion 501, and support end feet 502 biased to one side are provided at both ends of the arc groove portion 501. The support end feet 502 are supported on the inner wall of the hollow tube body 202, and the arc groove portion 501 is clamped with the outer wall of the overflow main pipe 4.

[0034] The pipe clamp 5 clamps the overflow main pipe 4 to prevent the overflow main pipe 4 from rotating and causing the overflow branch pipe 401 to be skewed.

[0035] Each cultivation tube 2 is arranged obliquely according to the flow direction, and the nutrient solution inlet and outlet 204 at the lower end is connected to the nutrient solution inlet and outlet 204 at the higher end of the cultivation tube 2 of the next layer through a hose, and the nutrient solution inlet and outlet 204 at the lower end of the cultivation tube 2 of the lowest layer finally discharges liquid.

[0036] The overflow pipe is a circulation structure. The upper end of the overflow main pipe 4 in the cultivation tube 2 of the highest layer is closed, and the lower end is connected to the upper end of the overflow main pipe 4 of the next layer. The lower end of the overflow main pipe 4 of the lowest layer is connected to the inside of the junction box 3 through a hose. When the flow rate of the nutrient solution entering from the highest nutrient solution inlet and outlet 204 decreases, the liquid pump 8 can be manually or automatically turned on, and the nutrient solution stored in the junction box 3 can flow back and enter from the highest nutrient solution inlet and outlet 204 to replenish the nutrient solution in the cultivation tube 2.

[0037] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
