The general support frame 12 comprises a square pipe, a crank, a screw rod adjusting rod and a U-shaped clamp. The bottom edge of the drill bit 20 is provided with sawteeth, the diameter of the drill bit 20 is 5cm-7cm, and the height of a cavity inside the drill bit 20 is 8cm-10 cm. The electronic scale 41 is internally provided with a memory card, and the electronic scale 41 is a 0.01g high-precision miniature electronic balance scale. The drill bit 20 is of a hollow structure, and one surface of the drill bit is provided with a soil falling opening of one fifth of a circle. The support is divided into a fixed part and a movable part, the fixed part is arranged on the rotary support 23 through screws, the movable part is connected with the 775 motor 24 through a rotating shaft, the lead screw stepping motor 21 is fixed on the movable part, and the lead screw 22 penetrates through the movable part. A corresponding recess is provided at the contact between arcuate wing 31 and electronic scale 41, and the top surfaces of arcuate wing 31 and electronic scale 41 are located on the same horizontal line.

Before the device is installed, a proper installation address needs to be found, for example, a place with convenient electricity taking or large difference in natural environment, for example, a place with a big tree shadow or a place close to a river, should not be selected. After the address is selected, if the power is inconvenient to get, the solar cell panel can be used for supplying power.

When the light collecting plate is installed, the base 10 is fixed on the ground, then the main supporting frame 12 is sequentially installed, the light collecting plate 11 is installed on the main supporting frame 12, and the direction of the light collecting plate 11 can be adjusted through a crank and a lead screw adjusting rod on the main supporting frame 12. And then a cooktop ring support 13 is arranged above the water tank. The length from the central point of the aluminum box 30 to the position of the rotating support 23 is measured, and then the rotating support 23 and the base 10 are connected together through a connecting rod, so that the whole support is prevented from being turned over when the rotating support 23 rotates. Firstly, a fixed support is installed, then a rotary support 23 is installed on the fixed support, and then a screw rod stepping motor 21, a screw rod 22 and a drill bit 20 are sequentially installed. The aluminum box 30, the arc-shaped wing 31, the cross bracket 40 and the electronic scale 41 are installed in this order. In order to prevent the aluminum box 30 from being deviated by strong wind, it is preferable that a groove corresponding to the arc wing 31 is formed on the upper surface of the electronic scale 41 or the two are fixed by other means such as double-sided tape. The aluminum can 30 may be displaced downward when weighed. Therefore, there is no direct contact between the aluminum case 30 and the bezel bracket 13. Under the control of the electric cabinet, when taking out soil, the screw rod stepping motor 21 drives the screw rod 22 and the drill bit 20 to move downwards to drill soil, and soil is remained in the drill bit 20. Because the pressure that produces when getting soil makes the earth compaction of being got together, can not lead to earth to drop when drill bit 20 moves upwards, simultaneously, also because drill bit 20 inside is wide outside narrow, further guaranteed that soil can not be got promptly and drop promptly.

After taking the soil, 775 motor 24 drives the movable part of rotary support 23 to rotate, and rotates drill bit 20 to the upper side of aluminum box 30, the condition that part of soil falls off can occur in the process of movement, and the soil can be taken several times more or if the weight of the soil falling into aluminum box 30 is enough, the soil can be ignored slightly.

When soil rotates to the position right above the aluminum box 30, the screw rod stepping motor 21 rotates back and forth within the width range of the aluminum box 30 under the control of the electric cabinet, so that the soil can be shaken down into the aluminum box 30. At this time, the value obtained by the electronic weighing device 41 is continuously recorded, and the number of the highest weight is the weight of the soil taken this time. The solar energy collected by the light collector plate 11 heats the aluminum case 30. The moisture contained in the soil in the aluminum box 30 is heated and evaporated until the final weight data is not changed, and the weight of the moisture can be obtained. And then calculating by a formula to obtain the soil moisture content. The experimenter only needs to take down the memory card and read the data in the memory card. And collecting or filling the soil in the aluminum box 30 to the place where the soil is taken.

The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
