Technical Field
[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampler. Background Art
[0002] Soil refers to a layer of loose material on the surface of the earth, composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals formed by weathering of rocks, animals and plants, organic matter produced by the decomposition of microbial residues, soil organisms, as well as water, air, and oxidized humus.
[0003] When testing the soil environment, a sampling tube is needed to sample the soil, insert the tube into the soil as a whole, and then lift it up to carry the soil out. However, for hard soil, it is not convenient to completely separate the soil block from the soil after the sampling tube is inserted. When lifting and extracting, the soil block is easily broken, and the sampling quality cannot be guaranteed. Therefore, we propose a soil sampler. Utility Model Content

[0024] See also Figure 1-4 The utility model provides a technical solution: a soil sampler, including a cylinder 1 and a vertical rod 2, the vertical rod 2 is vertically welded and fixed above the cylinder 1, the vertical rod 2 is connected to the middle position above the cylinder 1, and a grip 22 is horizontally fixed on the top of the vertical rod 2, and the grip 22 is fixed to the top of the vertical rod 2 by welding. Holding the vertical rod 2 by the handle can conveniently drive the cylinder 1 to move or raise or lower the height, and the grip can apply a force to the vertical rod 2 by the handle to drive the cylinder 1 to rotate an angle.
[0025] A ring knife 11 is arranged around the outer ring of the bottom of the cylinder 1, and the ring knife 11 is connected to the cylinder 1 as an integral structure. When the cylinder 1 is subjected to a downward pressure force, it can be pressed down into the soil through the ring knife 11, and a pedal rod 21 is transversely fixed at the bottom of the vertical rod 2. The vertical rod 2 vertically penetrates the middle position of the pedal rod 21, and the penetration position is fixed by welding. In order to make the cylinder 1 more smoothly pressed into the soil, the pedal rod 21 can be stepped on to apply force to the cylinder 1.
[0026] A rod 3 is vertically fixed in the middle of the cylinder 1, and a cone head 31 is provided at the bottom of the rod 3. The cone head 31 and the rod 3 are connected as an integral structure. When the cylinder 1 is subjected to a downward pressure, the rod 3 can be easily pressed down into the soil through the cone head 31. An annular groove 32 is provided around the outer ring of the bottom of the rod 3 above the cone head 31. The outer ring of the rod 3 is tied and connected with a steel wire 4 through the annular groove 32. A through hole 12 is provided on the surface of the cylinder 1 at the same height as the annular groove 32. The through hole 12 A groove 121 connected to the cylinder 1 is provided on the outer surface thereof, and the other end of the steel wire 4 passes through the cylinder 1 through the through hole 12 and is placed in the groove 121. A knot 41 is provided at the end of the steel wire 4, and the knot 41 is pressed against the inner surface of the groove 121, so that the steel wire 4 is tightened between the bottom of the insertion rod 3 and the cylinder 1. When the cylinder 1 and the insertion rod 3 are fully inserted into the soil, the steel wire 4 also breaks through the incision and is pressed into the soil, and then drives the cylinder 1 to rotate to cut the bottom of the soil sample and separate it from the soil.
[0027] When in use, the cylinder 1 and other structures below are held by the gripping rod 22 and the vertical rod 2, so that the cylinder 1 is against the soil surface at the position to be sampled, and the cylinder 1 and the vertical rod 2 are supported vertically and stably, and the cylinder 1 is pressed down into the soil through the ring knife 11 on the outer ring of the bottom by stepping on the pedal 21, so that the soil sample enters the interior of the cylinder 1. In this process, the insertion rod 3 is inserted into the soil through the cone head 31 at the bottom, and the steel wire 4 is also lowered, and the cylinder 1 is completely pressed down into the soil. Finally, the handle is used to drive the vertical rod 2 to rotate, so that the cylinder 1 also rotates. During the rotation, the steel wire 4 rotates to cut off the soil sample inside the cylinder 1 from the lower position and separate it from the soil. After the cylinder 1 is driven to make a complete rotation, the steel wire 4 is reset to its initial position again. At this time, the cylinder 1 is lifted and the insertion rod 3 is driven to rise. The steel wire 4 rises upward from the incision where it was originally pressed. After that, the clamp can be used to take out and collect the soil sample cut off by the steel wire 4 and the cylinder 1 as a whole.
