Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides an agricultural soil detects with device of fetching earth, includes a soil sampling section of thick bamboo 10, handle 20 and cross cutting knife 30, the symmetrical welding in soil sampling section of thick bamboo 10 top has handle 20, soil sampling section of thick bamboo 10 bottom is provided with the broken tool bit 11 of annular, the center department welding of soil sampling section of thick bamboo 10 outer wall both sides has running-board 12, the broken tool bit 11 of annular is inside to have cross cutting knife 30 through bolt fixed mounting, the cross-section of cross cutting knife 30 is the isosceles triangle structure, the edge of a knife of cross cutting knife 30 is seted up and is located the bottom.

Wherein, the front side of the outer wall of the soil sampling cylinder 10 is uniformly provided with scale marks 13; the scale marks 13 are arranged on the surface of the soil sampling cylinder 10, so that the depth of the soil sampling cylinder 10 extending into the soil can be determined, and the soil sampling depth of the soil sampling cylinder 10 can be determined.

The annular soil breaking cutter head 11 and the soil sampling cylinder 10 are of an integrated structure; the annular soil breaking cutter head 11 and the soil sampling cylinder 10 are arranged into an integral structure, so that the strength of the annular soil breaking cutter head 11 is improved, and the annular soil breaking cutter head 11 is prevented from deviating relative to the soil sampling cylinder 10.

The section of the annular soil breaking cutter head 11 is in a right-angled triangle structure, the opening of the edge of the annular soil breaking cutter head 11 is positioned at the bottom, and the opening inclination angle of the edge of the annular soil breaking cutter head 11 is 30 degrees; after the annular soil breaking cutter head 11 is inserted into soil, the annular soil breaking cutter head 11 is firstly contacted with the ground, and then the soil is broken by a knife edge at the bottom of the annular soil breaking cutter head 11, so that the soil taking cylinder 10 can conveniently extend into the soil.

Wherein, the height dimension of the bottom of the cross cutter 30 is larger than that of the bottom of the annular ground breaking cutter head 11; when carrying out the borrowing, the edge of a knife of the broken soil tool bit 11 bottom of annular contacts with ground earlier, then break open soil, then the broken soil tool bit 11 of annular stretches into soil, it is cut off by cross cutting knife 30 to enter into the inside earth pillar of a soil sampling section of thick bamboo 10 simultaneously, then the earth pillar after the cutting enters into a soil sampling section of thick bamboo 10, treat that a soil sampling section of thick bamboo 10 stretches into behind the appointed degree of depth, rotate a soil sampling section of thick bamboo 10 through handle 20, thereby drive cross cutting knife 30 and cut off the inside earth pillar bottom of a soil sampling section of thick bamboo 10, and hold the earth pillar after the cutting through the upper surface of cross cutting knife 30, then take out a soil sampling section of thick bamboo 10 through handle 20.

Wherein, the top angle of the isosceles triangle enclosed by the cross cutter 30 is 30 degrees.

The working principle is as follows: when the soil taking device is used, a proper soil taking place is selected firstly, then sundries on the soil taking ground are cleaned up, then the soil taking device is cut into the ground through the annular soil breaking cutter head 11, then a soil taking person steps on the pedal plate 12 to step the soil taking barrel 10 into the soil, after the soil taking barrel 10 extends into the specified depth, the soil taking barrel 10 is rotated through the handle 20, so that the cross cutting knife 30 is driven to cut off the bottom of a soil column inside the soil taking barrel 10, the cut soil column is supported through the upper surface of the cross cutting knife 30, then the soil taking barrel 10 is taken out through the handle 20, and the soil column is lifted out of the ground, so that the soil column is prevented from being separated from the soil taking barrel 10 in the lifting process, and the use is facilitated.
