[0025] Please refer to 3 - Figure 4 , in the embodiment of the present invention: The circulation device 8 includes a water supply tank 81, a circulation pump 82, a measuring tank 83, a shunt pipe 84, an electric control valve 85, a return tank 86, a soil discharger 87, and a return pipe 88. A circulation pump 82 is installed at the front end of the water supply tank 81. The circulation pump 82 is connected to the right end of the measuring tank 83. The shunt pipe 84 is connected to the right end of the measuring tank 83. The shunt pipe 84 is connected to the top of the liquid spraying nozzle 6. An electric control valve 85 is installed inside the shunt pipe 84. The return tank 86 is installed inside the incubator 1. A return pipe 88 is arranged at the rear end of the return tank 86. The top of the return pipe 88 is connected to the water supply tank 81. The soil discharger 87 is fixed inside the water supply tank 81. The measuring tank 83 and the circulation pump 82 are arranged horizontally at the front end of the water supply tank 81. An observation scale is provided on the outer side of the measuring tank 83 in contact, and a position measuring float is placed inside. An electric control valve 85 is arranged at the center of the shunt pipe 84.

[0026] Please refer to FIG. 5. In the embodiment of the present utility model: The soil discharger 87 includes a mounting frame 871, a filter screen 872, a driving motor 873, and a driving connecting rod 874. The mounting frame 871 is rotationally fitted with the inner bottom end of the water supply tank 81. The filter screen 872 is fixed to the inside of the mounting frame 871. The driving motor 873 is fixed to the inside of the water supply tank 81. The driving motor 873 is drivingly connected to the bottom of the driving connecting rod 874 by a coupling. The driving connecting rod 874 is drivingly connected to the bottom of the mounting frame 871. The top of the return tank 86 is an inverted trapezoid. The top of the mounting frame 871 is provided with a rectangular mounting groove, and the internal size of the mounting groove is the same as the size of the filter screen 872.

[0027] Reference Figure 1 - Figure 5 , during use, after opening the maintenance door 2, start the adjusting push cylinder 7 to push the culture rack 9 downward to a suitable position, then put the seeds and soil used during cultivation into the inside of the culture vessel and put them into the inside of the culture rack 9 together. Then turn on the temperature controller 3 and the sunlight lamp 5 to simulate the cultivation environment of the seeds, and then close the maintenance door 2;

[0028] At the same time, start the circulation pump 82 to pump the water and nutrient solution in the water supply tank 81 into the measuring tank 83. By observing the scale on the outside of the measuring tank 83 and the floating buoy placed inside, the measurement of the water source and nutrient solution to be sprayed can be observed, which is beneficial for experimental personnel to collect experimental data;

[0029] Start the electric control valve 85, so that the shunt pipe 84 guides the nutrient solution inside the measuring tank 83 into the inside of the liquid spraying nozzle 6 respectively, and then the liquid spraying nozzle 6 sprays it onto the culture rack 9, so that the seeds inside the culture vessel can normally adsorb nutrients and gradually grow inside the culture box 1;

[0030] Furthermore, by arranging the return tank 86 below the culture rack 9, the overflowing nutrient solution flows back to the return tank 86. During this process, start the driving motor 873 to drive the driving connecting rod 874 to swing. Since the driving connecting rod 874 pushes the mounting frame 871 to swing up and down along the return tank 86, the filter screen 872 shakes accordingly and filters the soil or impurities in the passing nutrient solution, preventing them from entering the inside of the circulation pump 82. Then, start the soil discharger 87 to discharge the soil and impurities carried in the nutrient solution, preventing the soil and impurities from causing the blockage of the circulation pump 82. Then, the filtered nutrient solution is guided back to the inside of the water supply tank 81 by the return pipe 88, which plays a role in recycling and reducing waste of the nutrient solution. Thus, the nutrient solution is recycled through the circulation device 8, and the recycled nutrient solution is filtered to ensure that the circulation pump will not be blocked when it flows back, thereby solving the problem that in traditional equipment, the soil is easily separated and enters the inside of the circulation pump along with the nutrient solution, causing the blockage of the circulation pump.
