Abstract
Description
Technical Field
[0001] The utility model relates to the field of soil survey and sampling, and more particularly to a survey and sampling device. Background Art
[0002] Soil exploration sampling, referred to as sampling, refers to the process of taking a representative portion of soil from the field, field, culture or cultivation unit; the soil sample obtained by sampling is prepared into an analytical sample after appropriate treatment. When performing soil sampling, a sampler is required, and the staff needs to manually operate the sampler to obtain soil. However, the outer wall of the existing sampler is prone to soil adhesion during sampling, which brings trouble to subsequent cleaning, and is easy to bring out soil below the ground, affecting the flatness of the soil surface. Utility Model Content
[0003] The utility model provides an exploration sampling device, which can prevent soil from adhering to the outer wall during sampling and prevent soil below the ground from being brought out.

[0005] Threaded holes are provided on the sampling cover A and the sampling cover B, and the sampling cover A and the sampling cover B can be fixed by bolts.
[0006] One end of the slot rod is fixedly connected with a handle.

[0015] See Figure 1 、 Figure 2 and Figure 3 ,
[0016] A survey and sampling device includes a base 101, a circular through hole is provided on the base 101, a rubber ring is bonded to the inner wall of the circular through hole, a slot rod 103 is rotatably connected to the base 101, a slide groove 104 is provided on the slot rod 103, a slide rod 201 is slidably connected in the slide groove 104, a sampling cover A202 is fixedly connected to the lower end of the slide rod 201, a sampling cover B203 is rotatably connected to the sampling cover A202, and the sampling cover A202 and the sampling cover B203 are buckled together to form a cylindrical tube with an opening at the lower end.
[0017] When using the survey and sampling device, the staff places the base 101 on the ground, then steps on the base 101 with both feet to fix it, and at the same time lifts up the slot rod 103 with his hands. The slot rod 103 drives the cylindrical tube formed by the sampling cover A202 and the sampling cover B203 to move downward, so that the cylindrical tube passes through, and the circular through hole on the base 101 contacts the soil. At this time, continue to lift up the slot rod 103, and the slot rod 103 slides on the slide rod 201, so that the cylindrical tube moves downward and then inserts into the soil. After the soil enters the cylindrical tube, the function of soil survey and sampling is realized.
[0018] During the movement of the cylindrical tube, the outer wall of the cylindrical tube contacts the rubber ring bonded in the circular through hole, and the rubber ring and the outer wall of the cylindrical tube generate friction. Then, when the cylindrical tube moves upward and leaves the soil, the rubber ring scrapes off the soil adhering to the outer wall of the cylindrical tube, thereby avoiding the trouble of the soil adhering to the outer wall when taking out the cylindrical tube, and under the shielding effect of the base 101, it can avoid bringing out the soil below the bottom surface, ensuring that the soil surface is flat.
[0019] See Figure 5 ,
[0020] Threaded holes 204 are provided on the sampling cover A202 and the sampling cover B203, and the sampling cover A202 and the sampling cover B203 can be fixed by bolts.
[0021] When taking soil samples, the sampling cover A202 and the sampling cover B203 are fixed with bolts, thereby preventing the sampling cover A202 and the sampling cover B203 from moving freely during sampling, thereby avoiding affecting the sampling effect. After sampling, the bolts are removed, and then the sampling cover B203 is rotated to open the cylindrical tube to take out the sampled soil.
[0022] See Figure 5 ,
[0023] One end of the slot rod 103 is fixedly connected to a handle 105 , which facilitates manual operation of the slot rod 103 by a worker.
[0024] See Figure 4 ,
[0025] The surface of the handle 105 is covered with a rubber sleeve, which acts as a buffer and can improve the comfort of the staff.
[0026] See Figure 5 ,
[0027] The lower ends of the sampling cover A202 and the sampling cover B203 are provided with sharp chamfers, which facilitate the insertion of the cylindrical tube formed by snapping the sampling cover A202 and the sampling cover B203 into the soil.
[0028] See Figure 3 ,
[0029] The upper end of the base 101 is fixedly connected to a limit ring 102 , and the limit ring 102 has the same diameter as the circular through hole.
[0030] The limiting ring 102 serves to limit the cylindrical barrel, ensuring that the cylindrical barrel can move vertically downward.
[0031] See Figure 5 ,
[0032] The sampling cover A202 and the sampling cover B203 are both made of stainless steel. The cylindrical tube formed by buckling the stainless steel sampling cover A202 and the sampling cover B203 has good rust resistance and strength.
[0033] See Figure 3 ,
[0034] A pedal for placing feet is provided on each of the left and right sides of the base 101. The pedals are convenient for workers to step on the base 101 with their feet, so as to facilitate fixing the base 101.
[0035] See Figure 3 ,
[0036] The limiting ring 102 is made of stainless steel, and the limiting ring 102 made of stainless steel has good wear resistance.
[0037] See Figure 3 ,
[0038] The handle 105 is made of wood, which can improve the comfort of use for staff.
