[0030] The technical solutions of the utility model are further illustrated below in combination with the drawings and through specific embodiments.
[0031] With reference to Figs. 1 to 4 The utility model embodiment provides a kind of soil detection sampling device, including fixed seat 10, support frame 20, sampling cylinder 30 and sampling component 40.Fixed seat 10 is circular, and fixed seat 10 is equipped with through hole.Support frame 20 includes the support rod 21 being set on fixed seat 10 and the support ring 22 being set on support rod 21, and the hole axis of support ring 22 center hole and the hole axis of through hole are on same straight line.Support rod 21 surrounds through hole, and it is equidistantly set.Sampling cylinder 30 is slidably connected with support rod 21, and sampling cylinder 30 can be slid between support ring 22 and fixed seat 10.Sampling component 40 includes the rotating shaft 41 being rotatably connected with support ring 22 and the auger blade 42 being set on rotating shaft 41.In the utility model embodiment, rotating shaft 41 is divided into two sections, and auger blade 42 is set on the section of rotating shaft 41 close to fixed seat 10.Connection ring 43 is arranged on support ring 22, and the inner ring surface of connection ring 43 is equipped with internal thread, and the other section of rotating shaft 41 is equipped with the external thread corresponding with internal thread.Connection ring 43 can be fixed on support ring 22.When connection ring 43 is fixed on support ring 22 and rotating rotating shaft 41, under the cooperation of the external thread of rotating shaft 41 and the internal thread of connection ring 43, rotating shaft 41 drives auger blade 42 to move up and down.
[0032] When collecting the soil sample, the fixed seat 10 is fixed on the ground, and then the sampling cylinder 30 is slid to the highest position, at this time, the sampling cylinder 30 is not in contact with the auger blade 42; then the rotating shaft 41 is rotated, the rotating shaft 41 drives the auger blade 42 to move downward and pass through the through hole on the fixed seat 10, and then the auger blade 42 digs the soil downward, while driving the surrounding soil to move upward, so that the soil at different depths is transported to the ground. Since the sampling cylinder 30 is located at the highest position and is not in contact with the auger blade 42, the soil transported to the ground will not fall into the sampling cylinder 30, but will fall outside the auger blade 42. When the required depth is reached, the sampling cylinder 30 is slid to make the sampling cylinder 30 in contact with the auger blade 42, so that the soil on the auger blade 42 falls into the sampling cylinder 30, thereby realizing deep soil sampling and improving the efficiency of collecting deep soil samples.
[0033] Further, the support rod 21 is provided with a sliding groove 23, and the outer circumferential surface of the sampling cylinder 30 is provided with a sliding block 31 corresponding to the sliding groove 23.

The end of the support rod 21 away from the fixed seat 10 is provided with a limiting groove 24, and the limiting groove 24 is in communication with one end of the sliding groove 23. When the sampling cylinder 30 is slid to the top end of the sliding groove 23, the sampling cylinder 30 is rotated to make the sliding block 31 enter the limiting groove 24, so that the sliding block 31 is limited in the limiting groove 24, and at this time, the sampling cylinder 30 is at the highest position.
[0034] Further, the upper surface of the connecting ring 43 is provided with an upper extension edge 44, and the lower surface of the connecting ring 43 is provided with a lower extension edge 45. The distance between the upper extension edge 44 and the lower extension edge 45 is slightly greater than the thickness of the supporting ring 22, that is, the supporting ring 22 is partially clamped into the limiting space formed by the upper extension edge 44 and the lower extension edge 45. The outer side surface of the connecting ring 43 is in abutment with the inner side surface of the supporting ring 22.
[0035] The upper extension edge 44 is provided with a bolt hole 46, and the supporting ring 22 is provided with a plug slot (not shown in the figure) corresponding to the bolt hole 46, and the connecting ring 43 is fixed to the supporting ring 22 by a bolt. During the process of collecting the soil sample, when the auger blade 42 reaches the required depth and there is a lot of broken soil around the auger blade 42, the depth of the soil does not need to be dug further, the bolt can be pulled out, and the connecting ring 43 is rotatably connected with the supporting ring 22. At this time, the rotating shaft 41 is rotated, and the auger blade 42 can drive the broken soil to move upward and fall into the sampling cylinder 30.
