The utility model discloses a method for using device fetches earth in agriculture and forestry ground, including following step:

(1) sampling soil: the position of the soil sample point to be detected is selected, the soil drill is vertically inserted into the soil, the rectangular column extension rod 2 and the soil-taking drill bit 5 are provided with scale values of standard length sizes from bottom to top, so that the distance of the soil drill extending into the soil can be observed, and the soil sample can be obtained by directly pulling out the soil drill.

When the texture to be taken is hard, the handle 3 can be rotated, the wrench 6 is taken out from the wrench clamping groove 4 and inserted into the handle 3, and the wrench is rotated; if still rotate motionlessly, then block the end opening card of spanner 6 on the outer pipe wall of rectangular column extension rod 2, the point of choosing is decided along with the degree of depth that the earth drill head inserted into soil, can adjust at will, rotates 6 handles of spanner and can drive the earth drill and rotate.

(2) And (4) retaining a soil sample: after the depth of the soil layer is observed, the soil in the soil taking drill bit is cleaned to a prepared soil sample aluminum box by a scraper, and a mark is made for researching the soil property at the later stage.

In the using process, attention needs to be paid to:

(1) the wrench 6 can be fixed on the wrench slot 4, can be inserted into the handle 3, and can also be inserted into the outer pipe wall of the rectangular column extension rod 2. When loose soil is taken, the wrench 6 can be vertically inserted into the wrench clamping groove 4 (namely, the wrench 6 is not used), and the handle 3 is rotated to finish soil taking; when harder soil is taken, the wrench 6 can be directly inserted into the handle 3, the insertion length is adjusted as required, and the handle becomes a long stress point by utilizing the lever principle, so that two persons can cooperatively take the soil, and more labor is saved; when getting darker soil, when independent twist grip 3 does not have the effect, can insert the end opening of spanner 6 on the outer pipe wall of rectangular column extension rod 2, through rotating spanner 6, make whole auger rotate.

(2) The width of the wrench 6 is approximately equal to the inner diameter of the wrench clamping groove 4, approximately equal to the inner diameter of the T-shaped handle 3 circular tube, and approximately equal to the width of the extension rod rectangular column 2, so that the wrench 6 can be well fitted on the extension rod rectangular column.

(3) In general, according to most soil drills in the market, the handle 3 is 29.6cm, the rectangular column extension rod 2 is 77.1cm, the soil sampling drill bit 5 is preferably 25.1cm, and the wrench 6 is preferably 59.1cm, so that the requirements of soil sampling measurement can be basically met.

In practical application, when the length of the handle 3 is 29.6cm, the length of the wrench 6 is not more than 77.1cm and not less than 59.1cm, so that the force points with a certain distance can be guaranteed when a person holds the handle, and the wrench 6 can be easily taken down after being inserted into the wrench clamping groove 4. The thickness of the wrench is preferably 1cm, which not only can make the wrench 6 have good strength, but also can make the wrench 6 not too heavy, so as to be convenient to carry.

(4) The whole earth drill is preferably made of stainless steel; because the bottom end of the soil taking drill bit is provided with the annular cutter edge, the soil taking drill bit is light in weight and can be conveniently and vertically inserted into soil with different depths and materials.

(5) In the case of the soil sampling device which is not practical, the wrench 6 is preferably inserted into the wrench clamping groove 4, so that not only can the space be saved, but also the soil drill can be conveniently carried to the field.

In summary, the soil sampling device provided by the utility model comprises a handle 3, a rectangular column extension rod 2, a wrench slot 4, a soil sampling drill bit 5 and a rubber handle sleeve 1, wherein the handle 3, the rectangular column extension rod 2 and the soil sampling drill bit 5 are welded into a whole, and the rectangular column extension rod 2 is provided with a scale value with standard size, so that the soil sampling device can be vertically inserted into the soil to complete soil sampling; when the earth drill is not moved, the wrench 6 can be extended into the handle 3 for continuous use, or the wrench 6 can be directly inserted into the proper position of the rectangular column extension rod 2 for continuous use. Therefore, the utility model discloses an agroforestry soil sampling device not only easily operates, conveniently carries, can bore moreover and get the harder soil sample of soil, and this has important meaning to open-air soil sampling. Meanwhile, the wrench 6 can be inserted into the slot 4 when the device is not used, so that the device is convenient to carry.
