[0035] Three storage boxes 11 are provided, so that soil under different vegetation can be placed inside the three storage boxes 11 respectively.

[0036] The drying mechanism includes a vertical plate 17. The vertical plate 17 is fixed to one end of the top of the bottom plate 1 away from the electronic scale 16. A hot air blower 18 is fixed to the top of one side of the vertical plate 17. The air outlet end of the hot air blower 18 is connected to an air supply pipe 19. The end of the air supply pipe 19 passes through the interior of the vertical plate 17. A nozzle 20 is arranged at the bottom of the air supply pipe 19.

The design of the dust filter 22 has a dust blocking effect, thereby improving the accuracy of the experiment.

[0038] Working principle: When using the soil moisture content detection device for the rainwater storage capacity experiment of different vegetation, firstly, put the soil under different vegetation into the three storage boxes 11, and ensure that the soil is in a broken state, then use the electronic scale 16 to obtain the weight of the three storage boxes 11 filled with soil, and ensure that the weight is the same, and obtain the total weight of the undried soil and the storage box 11, and record it;

[0039] Then, the three storage boxes 11 are placed inside the three grooves 10 respectively, and then the handle 14 is rotated. At this time, the handle 14 drives the screw rod 12 to rotate. Since the middle part of one side of the clamping plate 13 is rotatably mounted with the screw rod 12 through the bearing, the movable plate 4 and the screw rod 12 are threadedly connected, and the limit rod 15 and the movable plate 4 are slidably connected, the screw rod 12 pushes the clamping plate 13 to move close to the storage box 11, cooperates with the inner wall of the groove 10, and completes the fixation of the storage box 11. Similarly, the fixation of the other two storage boxes 11 is completed;

[0040] Then, the hot air blower 18 is started, and the hot air generated by the hot air blower 18 is sprayed from the three nozzles 20 to the inside of the three storage boxes 11 through the air supply pipe 19, so as to dry the soil inside the three storage boxes 11 at the same time, thereby improving the working efficiency;

[0041] Then, the motor 9 is started, and then the motor 9 drives the cam 8 to rotate through the rotating shaft 7. When the protruding end of the cam 8 is close to the movable plate 4, the cam 8 pushes the movable plate 4 to move upward, and the spring 5 is compressed. When the protruding end of the cam 8 is away from the movable plate 4, the elastic force generated by the spring 5 causes the movable plate 4 to move downward. As a result, when the motor 9 keeps rotating, the movable plate 4, the three storage boxes 11, and the soil inside the three storage boxes 11 vibrate up and down at the same time, so that the soil can fully contact with the hot air, thereby improving the efficiency of soil drying.

[0042] When the soil is dried, the three storage boxes 11 are measured separately by an electronic scale 16 to obtain the total weight of the dried soil and the storage box 11, which is recorded. Then, the total weight of the undried soil and the storage box 11 is subtracted from the total weight of the undried soil and the storage box 11 to obtain the weight of the water. Then, the weight of the undried soil is subtracted from the weight of the storage box 11 to obtain the weight of the undried soil. Then, the weight of the water is divided by the weight of the undried soil to obtain the soil moisture content. Then, the soil moisture content under three groups of different vegetation is obtained according to the above calculation method, and the rainwater storage capacity of different vegetation can be judged.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
