Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. 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.
In the present specification, the terms "upper", "lower", "left", "right", "middle", and the like are used for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.
Example 1
As shown in fig. 1 and 2, the present embodiment provides a soil column excavating tool for testing, which includes a shovel head 1, a ripper 2, and a shovel handle 3.
Preferably, as shown in fig. 2, the shovel head 1 has saw teeth 101 on one side and blades 102 on the other side, which makes the shovel head 1 more easily inserted into the earth pillar to shovel the earth, thereby better improving the digging efficiency of the digging tool.
Further preferably, the shovel head 1 is provided with a scale 4 in its axial direction, which makes it more convenient to measure the excavation depth of the earth pillar.
specifically, the upper part of the rod-shaped ripper 2 forms a conical sharp part 201, one end of the ripper 2 far away from the sharp part 201 is detachably connected with the shovel head 1, and one end of the ripper 2 close to the sharp part 201 is detachably connected with the shovel handle 3. Sharp portion 201 is used for turning over the soil to inseparabler soil to make things convenient for spade head 1 shovel more, and then improved this a soil column digging tool's for test digging efficiency. It should be noted that the spade handle 3 can also be directly connected to the spade head 1, so as to facilitate the spade operation of the spade head 1.
Preferably, the ripper 2 is in threaded connection with the shovel head 1, and the ripper 2 is in threaded connection with the shovel handle 3, so that the ripper 2 is more easily and conveniently mounted on the shovel head 1 and the ripper 2 is more conveniently mounted on the shovel handle 3.
further, the longitudinal section of the shovel handle 3 is T-shaped. Moreover, the earth pillar digging tool for the test comprises connecting parts 5, wherein the two connecting parts 5 are symmetrically arranged at two sides of the shovel handle 3; the connection part 5 is a quarter circle, and one end of the connection part 5 is connected with the horizontal part of the shovel handle 3, and the other end is connected with the vertical part of the shovel handle 3. Connecting portion 5 makes this a soil column digging tool for test more conveniently hang on the wall, and then more conveniently deposits.
