[0002] Patent No. CN218156948U discloses a soil moisture sampling and analysis mechanism. The utility model has a reasonable structural design. The device realizes the lifting and lowering of the drill bit. Two sets of rotating wheels are installed at the rear end of the sliding seat.

DETAILED DESCRIPTION
[0019] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.
[0020] refer to Figure 1-3 The utility model provides a technical solution: a soil moisture sampling and analysis device, including a sampling box 1, the upper end surface of the sampling box 1 is fixedly connected with a first servo motor 4, by setting the first servo motor 4, when the first servo motor 4 is rotating, the soil is acquired and transferred to the sieve plate 7, the output end of the first servo motor 4 passes through the side wall of the sampling box 1 and is fixedly connected with an electric telescopic push rod 5, by setting the electric telescopic push rod 5, it is convenient to control the up and down movement of the spiral blade 6, and the model is set to ZC001A, the telescopic end of the electric telescopic push rod 5 is fixedly connected with the spiral blade 6, the left side of the sampling box 1 A second servo motor 12 is fixedly connected. By setting the second servo motor 12, the second servo motor 12 can control the rotation of the fixed rod 13 when working. The fixed rod 13 is installed at the output end of the second servo motor 12. A slide groove 8 is opened on the inner wall of the sampling box 1. A telescopic rod 10 is fixedly connected in the slide groove 8. The top of the telescopic rod 10 is fixedly connected to a sieve plate 7. By setting the sieve plate 7, the soil and the impurities carried can be screened. A soil moisture detector body 16 is fixedly installed on the side wall of the sampling box 1. By setting the soil moisture detector body 16, the moisture content in the soil can be detected.
[0021] A first through hole 9 is provided at the center of the upper end surface of the sieve plate 7 , and a second through hole 15 is provided in the sampling box 1 .
[0022] Among them, the end of the fixed rod 13 facing away from the second servo motor 12 passes through the side wall of the sampling box 1 and is fixedly connected with a cam 14. By setting the cam 14, when the side with a longer diameter of the cam 14 is facing downward, the screening plate 7 is hit to accelerate the screening of the soil. The side with a longer diameter of the cam 14 overlaps with the upper end surface of the screening plate 7.
[0023] Among them, a spring 11 is sleeved on the surface of the telescopic rod 10. By setting the spring 11, when the cam 14 is separated from the sieve plate 7, the spring 11 uses its own elastic force to control the sieve plate 7 to slide in the slide groove 8, thereby achieving the up and down hitting of the sieve plate 7.
[0024] The bottom end of the spring 11 is fixedly connected in the slide groove 8 , and the top end of the spring 11 is fixedly connected to the lower end surface of the sieve plate 7 .
[0025] Among them, an installation opening is opened on the front of the sampling box 1, and a box door 2 is installed in the installation opening. A handle 3 is fixedly connected to the front of the box door 2. By setting the handle 3, it is convenient to flip the box door 2.
[0026] The working principle of the utility model is as follows: when in use, the staff starts the first servo motor 4 and the second servo motor 12 at the same time. When the first servo motor 4 is working, it controls the electric telescopic push rod 5 and the spiral blade 6 to rotate. When the spiral blade 6 is screwed into the soil, the soil is sampled. After completing this process, the electric telescopic push rod 5 starts to control the spiral blade 6 to move upward. At this time, the first servo motor 4 rotates again to rotate the soil onto the sieve plate 7. At the same time, the second servo motor 12 starts to control the rotation of the fixed rod 13 and the cam 14. When the side with a longer diameter of the cam 14 is downward, the sieve plate 7 is struck. At the same time, the spring 11 and the telescopic rod 10 are squeezed. When the cam 14 is separated from the sieve plate 7, the spring 11 starts to use its own elastic force to control the sieve plate 7 to move upward, so as to achieve the up and down shaking of the sieve plate 7 and accelerate the screening of the soil. When it falls into the box, the soil will slide along the slope toward the soil moisture detector body 16 for easy detection.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and utility model concept of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
