A rectangular cultivation box A4 is placed below the centers of the placement bracket A1 and the placement brackets B7, and a rectangular cultivation box B5 is placed above the centers of the placement bracket A1 and the placement brackets B7. The shapes, sizes, and structural compositions of the placement bracket A1 and the placement brackets B7 are the same. The placement bracket A1 is mainly composed of two placement columns and two placement rods. The two placement columns are symmetrically arranged front and rear, and the two placement rods are respectively welded to the upper and lower sides of the centers of the two placement columns. The rectangular cultivation box A4 and the rectangular cultivation box B5 are respectively placed on the two placement rods. The placement columns and the placement rods are both made of aluminum alloy. The bottom ends of the placement columns are welded with placement bases, and the length and width of the placement bases are both greater than those of the placement columns. The distance between the two placement columns is greater than the widths of the rectangular cultivation box A4 and the rectangular cultivation box B5. When using the soilless cultivation device for vegetable planting, first, the placement bracket A1 and the placement brackets B7 need to be stably and firmly placed in the planting greenhouse. At this time, the placement bracket A1 and the placement brackets B7 are connected into a firm whole by the two metal connecting frames A2 and the two metal connecting frames B. Then, the rectangular cultivation box A4 and the rectangular cultivation box B5 need to be respectively placed on the two groups of placement rods. At this time, the rectangular cultivation box A4 and the rectangular cultivation box B5 are both placed in a horizontal state. Then, the cultivation box covers 9 need to be respectively placed on the tops of the rectangular cultivation box A4 and the rectangular cultivation box B5. Then, it is necessary to prepare for soilless cultivation of vegetables on the rectangular cultivation box A4 and the rectangular cultivation box B5.

[0021] As Figure 1 and Figure 2As shown in the figure, drain pipe heads 8 are provided at the right ends of the cuboid cultivation box A4 and the cuboid cultivation box B5, and water inlet pipe heads are provided at the left ends of the cuboid cultivation box A4 and the cuboid cultivation box B5. The water inlet pipe heads and the drain pipe heads 8 can be connected to the external water supply pipe and the drain pipe. Cultivation box covers 9 are provided at the tops of the cuboid cultivation box A4 and the cuboid cultivation box B5. A plurality of cultivation holes 10 are equidistantly arranged inside the cultivation box covers 9, and cultivation net covers 11 are placed in the cultivation holes 10. When soilless cultivation of vegetables is carried out on the cuboid cultivation box A4 and the cuboid cultivation box B5, the water supply pipe head and the drain pipe head 8 need to be connected to the external water supply pipe and the drain pipe respectively. Then, the vegetable seedlings to be planted are placed into the cultivation net covers 11 inside the cultivation holes 10, and the cultivation liquid is injected into the cuboid cultivation box A4 and the cuboid cultivation box B5 through the water supply pipe. The vegetable seedlings in the cultivation net covers 11 will absorb the nutrients in the cultivation liquid and grow, so as to achieve the purpose of soilless cultivation.

[0022] As Figure 1 , Figure 3 and Figure 4 shown in the figure, cultivation box lifting devices 6 are provided at the bottoms of the cuboid cultivation box A4 and the cuboid cultivation box B5. The cultivation box lifting device 6 at the bottom of the cuboid cultivation box B5 includes a metal lifting frame 12, a lifting screw 13, a screw perforation 14 and an adjusting nut 15. A plurality of screw perforations 14 are arranged inside both metal connecting frames B3. Lifting screws 13 are provided at the tops of the front and rear ends of the metal lifting frame 12. The metal lifting frame 12 is located at the bottom of the cuboid cultivation box B5. The two lifting screws 13 respectively pass through the screw perforations 14 inside the two metal connecting frames B3, and adjusting nuts 15 are threadedly sleeved on the outsides of the two lifting screws 13. The two adjusting nuts 15 are respectively located at the tops of the two metal connecting frames B3.

[0023] As Figure 1 , Figure 3 and Figure 4As shown in the figure, the lifting screw 13 can move up and down in the screw perforation 14. The adjusting nut 15 can move up and down outside the lifting screw 13 by rotation. Both the lifting screw 13 and the metal lifting frame 12 are made of aluminum alloy. After the cuboid cultivation box A4 and the cuboid cultivation box B5 are both placed on the placement bracket A1 and the placement bracket B7, multiple cultivation box lifting devices 6 are needed to respectively support the suspended bottoms of the cuboid cultivation box A4 and the cuboid cultivation box B5 to prevent damage to the suspended parts of the cuboid cultivation box A4 and the cuboid cultivation box B5 due to excessive weight. Taking the cultivation box lifting device 6 at the bottom of the cuboid cultivation box B5 as an example, first, the adjusting nuts 15 outside the two lifting screws 13 need to be removed. Then, the two lifting screws 13 need to be passed through the screw perforations 14 inside the two metal connecting frames B3 from bottom to top. Then, the two adjusting nuts 15 are sleeved onto the outside of the tops of the two lifting screws 13 again, and the two adjusting nuts 15 are rotated so that the two adjusting nuts 15 are fully threadedly sleeved on the outside of the two lifting screws 13. Then, the adjusting nuts 15 are continuously rotated, and the adjusting nuts 15 continue to move downward outside the lifting screws 13. Since the adjusting nuts 15 are blocked at the top of the metal connecting frame B3, as the adjusting nuts 15 continue to move downward outside the lifting screws 13, the lifting screws 13 will be pulled upward by the blockage of the metal connecting frame B3. And the upward movement of the lifting screws 13 will slowly lift the metal lifting frame 12 until the metal lifting frame 12 supports the bottom of the cuboid cultivation box B5. Then, the multiple cultivation box lifting devices 6 are installed on the two metal connecting frames B3 in the same operation manner, and the multiple cultivation box lifting devices 6 are adjusted. In this way, the multiple metal lifting frames 12 will all support the suspended positions at the bottom of the cuboid cultivation box B5. When a large amount of cultivation liquid is injected into the cuboid cultivation box B5, the metal lifting frame 12 can resist the weight of the cultivation liquid at the suspended part at the bottom of the cuboid cultivation box B5, thereby avoiding the deformation and damage of the suspended part at the bottom of the cuboid cultivation box B5 due to excessive weight.
