[0044] In the third embodiment, on the basis of the first and second embodiments, referring to Figures 10 to 12 As shown in the figure, the liquid guide assembly 3 comprises a water culture box 32, the water culture box 32 is provided in three groups, the surfaces of the three groups of water culture boxes 32 are all provided with a flow guide groove 33, the outer surfaces of the flow guide grooves 33 are all fixedly installed with a positioning ring 34, the inside of the positioning ring 34 is fixedly installed with a filter cover 35, and the outer surface of the filter cover 35 is fixedly installed with a bent pipe 31. The culture solution is sprayed into the water culture box 32 through the spraying pipe 41, the bent pipe 31 installed outside the water culture box 32 guides the flow of the culture solution, so that the sprayed culture solution is transported into the multi-layer water culture box 32 along the bent pipe 31, and the filter cover 35 installed in the inside of the flow guide groove 33 filters and separates the impurities and precipitates in the water culture box 32, so that the vegetable seedlings placed in the cultivation assembly 6 are in contact with the culture solution soaked in the water culture box 32, and the impurities and precipitates in the culture solution during the transportation do not cause the blockage of the bent pipe 31.

[0045] The water culture box 32 is fixedly installed at the top of the positioning frame 44, the water culture box 32 is installed between the opposite surfaces of the side support frame 43 through the positioning frame 44, and the water culture boxes 32 are connected through the bent pipes 31.

[0046] The filter cover 35 comprises an extension pipe 351, a clamping frame 352 is fixedly installed on the outer surface of the extension pipe 351, a support strip 354 is clamped in the inside of the clamping frame 352, and a protective net 353 is fixedly installed on the surface of the support strip 354.

[0047] The extension pipe 351 is fixedly installed on the surface of the positioning ring 34, and extends through the flow guide groove 33 to the surface of the bent pipe 31. When the culture solution flows in the water culture box 32, impurities and precipitates in the water culture box 32 will flow to the position of the protective net 353 along with the liquid flow. The support strip 354 and the protective net 353 intercept and filter the impurities and precipitates. The support strip 354 arranged in a semicircular shape enables the protective net 353 to be arranged in an arc shape. The convex arc-shaped protective net 353 can reduce the contact area with the impurities, thereby avoiding that the impurities block the flow guide groove 33 when the culture solution flows. The support strip 354 and the clamping frame 352 are detachably connected, so as to facilitate the disassembly and cleaning of the protective net 353.

[0048] In use, the staff plants the vegetable seedlings in the cultivation assembly 6, and then starts the hydraulic jack cylinder 2 to drive the positioning rod 5 and the cultivation assembly 6 to move downward. At this time, the cultivation assembly 6 slides on the surface of the spraying assembly 4 to above the liquid guide assembly 3. Then the staff starts the spraying assembly 4 to spray the culture solution into the cultivation assembly 6 to cultivate the vegetable seedlings, and to collect the culture solution in the liquid guide assembly 3. The liquid guide assembly 3 delivers the culture solution in layers, so that the vegetable seedlings can be in uniform contact with the culture solution, and the nutrient solution can be uniformly distributed in the liquid guide assembly 3, avoiding local over-concentration or under-concentration.

[0049] The staff plants the vegetable seedlings in the seedling tray 63 in the cultivation groove 62, and starts the spraying pipe 41 to spray the culture solution to collect in the water culture box 32. Then the staff starts the hydraulic jack cylinder 2 to drive the positioning rod 5 and the sleeve frame 65 installed outside the positioning rod 5 to move above the water culture box 32, so as to adjust the position of the root system of the vegetable seedlings and the culture solution.

[0050] The shelf plate 633 groove seat 631 is installed between the cultivation groove 62 and the horizontal rod 61. When the vegetable seedlings are planted, the root system will spread outward through the arc groove 636. The inclined guide pad 635 arranged at the bottom of the groove seat 631 is arranged in a special-shaped structure with high middle and four low seats, which can prevent impurities in the culture solution from accumulating below the root system of the vegetable seedlings, thereby reducing the accumulation of bacteria and microorganisms around the root system. The cultivation semicircular cover 632 is independently arranged to separate the planting positions of the vegetable seedlings, so that the root system of each vegetable seedling can uniformly absorb the nutrients in the culture solution.

[0051] The valve of the spraying pipe 41 is opened to spray the culture solution into the cultivation assembly 6.

Then the staff member discharges the culture solution in the liquid guide assembly 3, sprays new culture solution into the cultivation assembly 6 through the spraying pipe 41, which can reduce the accumulation of bacteria and microorganisms around the root system, and make the water flow and air contact area larger, which is helpful for oxygen to dissolve into water.

[0052] The culture solution is sprayed into the water culture box 32 through the spraying pipe 41. The bending pipe 31 installed outside the water culture box 32 guides the culture solution to be sprayed to be transported to the multi-layer water culture box 32 along the bending pipe 31. When the culture solution flows, the filter cover 35 installed inside the guide groove 33 filters the impurities and precipitates in the water culture box 32, so that the vegetable seedling placed in the cultivation assembly 6 contacts with the culture solution soaked in the water culture box 32, and the impurities and precipitates in the culture solution during transportation do not cause the bending pipe 31 to be blocked.

[0053] When the culture solution flows in the water culture box 32, the impurities and precipitates in the water culture box 32 will gather at the position of the protective net 353 along with the liquid flow. The support strip 354 and the protective net 353 intercept and filter the impurities and precipitates. The support strip 354 is arranged in a semicircular shape, so that the protective net 353 is arranged in an arc shape. The convex arc-shaped protective net 353 can reduce the contact area with the impurities, so as to avoid that the impurities block the guide groove 33 when the culture solution flows. The support strip 354 and the clamping frame 352 are detachably connected, so that the protective net 353 can be disassembled and cleaned.
