It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0025] Embodiment 1

[0026] To solve the problems that the overall length of the existing electric soil sampler is inconvenient to adjust, and thus it is not convenient to carry, and it is difficult to conveniently take soil samples at different heights, please refer to Figures 1-4 , a portable electric soil sampler provided by the present utility model can conveniently adjust the overall length of the soil sampler and can conveniently take soil samples at different heights. It includes an installation tube 3 and a soil sampling tube 1 detachably fixed to the front end of the installation tube 3. A serrated ring 2 is detachably fixed to the front end of the soil sampling tube 1 to facilitate soil sampling. A handheld driving mechanism 4 for driving the installation tube 3 to rotate is provided at the rear end of the installation tube 3. By driving the installation tube 3 to rotate through the handheld driving mechanism 4, the installation tube 3 drives the soil sampling tube 1 to rotate, and the soil sampling tube 1 drives the serrated ring 2 to rotate. The soil is rotationally cut by the serrated ring 2, and during the downward pressing process of the electric soil sampler, the soil is guided into the soil sampling tube 1.

[0027] The soil sampling tube 1 is spliced by at least one tube body unit 101, and adjacent tube body units 101 are detachably fixed. The lengths of the tube body units 101 are set in multiple specifications, specifically, different length specifications such as 1 cm, 2 cm, 4 cm, 5 cm, and 10 cm can be set. Multiple tube body units 101 with different lengths are combined and spliced into a soil sampling tube 1 with the required length, which can meet the soil sampling requirements of different needs.

[0028] The docking surfaces between the serrated ring 2 and the pipe body unit 101, between the installation pipe 3 and the pipe body unit 101, and between adjacent pipe body units 101 are all fixed through a plug-in structure. The plug-in structure includes a plug rod 101a located on one end surface of the docking surface, a jack 101b located on the other end surface of the docking surface, and a groove 101d corresponding to the position of the jack 101b. The plug rod 101a is movably inserted into the jack 101b, and a setscrew knob 101c for locking the plug rod 101a is provided in the groove 101d; an arc-shaped plate 101e for closing the groove 101d is provided at the groove 101d. One side of the arc-shaped plate 101e is hinged to the pipe body unit 101, and the other side is buckled to the pipe body unit 101.

[0029] When the pipe body units 101 are spliced, insert the plug rod 101a into the jack 101b, then lock the plug rod 101a in the jack 101b through the setscrew knob 101c, and then close the arc-shaped plate 101e; the segmented design of the soil sampling pipe 1 enables it to adjust the length of the entire soil sampling pipe 1 based on actual needs, obtain soil samples at different depths, and ensure the integrity of the soil samples at the same time.

[0030] The hand-held driving mechanism 4 includes a mounting seat 402 and a motor 401 fixed on the end surface of the mounting seat 402; the output shaft of the motor 401 is fixedly inserted into the center of the end surface of the installation pipe 3. A rechargeable battery is installed in the mounting seat 402, and two armrests 403 are fixed on the side surface of the mounting seat 402. A switch for controlling the operation of the motor 401 is integrated on one of the armrests 403. The entire soil sampler can be easily picked up and placed through the two armrests 403.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, in order to improve the integrity of the soil sample, as Figure 5 shown, it further includes a cover plate 6 that matches the pipe body unit 101. After the sampling is completed, both ends of the soil sampling pipe 1 are closed by the cover plate 6; elastic clamping columns 601 are provided on the cover plate 6, and clamping holes 101f are provided on the end surface of the pipe body unit 101. The elastic clamping columns 601 are in clamping fit with the clamping holes 101f.

[0033] After taking the soil sample, directly disassemble the pipe body unit 101, and then close both ends of the disassembled pipe body unit 101 through the two cover plates 6 to ensure the integrity of the taken soil sample.

[0034] Embodiment 3

[0035] On the basis of Embodiment 1 and Embodiment 2, in order to further improve the integrity of the soil sample and ensure that the end surface of the soil sample can remain flat when the pipe body unit 101 is separated, as Figure 4As shown in the figure, perforations 301 are provided on the cylindrical surface of the installation pipe 3, and a cutting plate 5 for cutting off soil samples is inserted into the perforations 301. A pulling hole 501 is provided on the cutting plate 5, and three inserting rods 101a are provided, which are distributed on the end surface of the pipe body unit 101 at intervals of 90 degrees, and an opening gap for inserting the cutting plate 5 is formed.

[0036] When multiple pipe body units 101 need to be disassembled to obtain soil samples at different depths and are also convenient to carry after disassembly, first loosen the setscrew knob 101c and pull the pipe body unit 101 outwards for a short distance. At this time, the inserting rod 101a is still inserted into the insertion hole 101b, and a gap for inserting the cutting plate 5 is formed between the pipe body units 101. Pull out the cutting plate 5 from the installation pipe 3 and insert it into the gap to separate the soil and ensure the flatness of the end surface.

[0037] The above embodiments only represent one implementation manner of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
