Problems solved by technology

[0004] First, the stopper is hinged to the inner wall of the sampling shovel. Since the sampling shovel is usually circular, the free end of the stopper that can be turned over is located at the diameter of the circular sampling shovel. Affected by the limiting effect of the arc-shaped side wall, the stopper actually The slice cannot be turned over to the inside of the sampling shovel;

specific Embodiment 1

[0025] like Figure 1 to Figure 4 Shown is a schematic structural diagram of a cohesive soil sampling device described in this embodiment.

[0026] A kind of non-cohesive soil sampling device described in this embodiment comprises: a cylindrical sampling cylinder, and the sampling cylinder comprises a sampling top 1 and a sampling bottom 2 which are screwed to each other, and the sampling bottom 2 is provided with a fixed Block 4 and movable block 3, the fixed block 4 is fixedly arranged on the inner wall of the sampling bottom 2, the movable block 3 is connected to the fixed block 4 through the central rotating shaft 5, and the movable block The sheet 3 is located below the fixed blocking sheet 4, the central rotating shaft 5 is coaxially arranged with the sampling cylinder, and the top surface of the movable blocking sheet 3 is composed of two fan-shaped plates 31 symmetrical to the central rotating shaft 5 , the radians of the two fan-shaped plates 31 are 90°, the structur...

specific Embodiment 2

[0030] like Figure 5 Shown is a schematic structural diagram of a cohesive soil sampling device described in this embodiment.

[0031] The non-cohesive soil sampling device described in this embodiment has one central sampling part 8, and the rest of the structure is the same as that in Embodiment 1.

[0032] During sampling, at first rotate described movable shutter 3, make described fixed shutter 4 and described movable shutter 3 be in figure 2 Shown state, then by hammering the oblate gasket 62 or pressing down the pressure handle 61 by manpower, the sampling cylinder is penetrated into the sampling depth, and the soil layer sample entering the sampling cylinder lifts up the Said sampling indicating block 7, and said limit guide post 71 is moved upwards, analysis and sampling personnel can observe the sampling depth in real time according to the scale on the surface of said limit guide post 71, and stop pressing down said sampling after reaching the predetermined depth. ...

Abstract

The invention discloses a cohesionless soil sampling apparatus. The apparatus comprises a cylindrical sampling cylinder, the sampling cylinder comprises a sampling top and a sampling bottom which are in threaded connection, the sampling bottom is provided with a fixed separation blade and a movable separation blade, the fixed separation blade is fixedly arranged on the inner wall of the sampling bottom, the movable separation blade is connected with the fixed separation blade through a center rotating shaft, the movable separation blade is positioned below the fixed separation blade, the center rotating shaft and the sampling cylinder are coaxially arranged, the top surface of the fixed separation blade is formed by two sector-shaped plates symmetrical to the center rotating shaft, the radian of each of the sector-shaped plates is 90DEG, the structure of the movable separation plate is same to the top surface of the fixed separation plate, and the top surface of the movable separation blade and the fixed separation blade are respectively vertical to the center rotating shaft. The bottom of the sampling cylinder can be conveniently closed without loss of a sampling amount, so the soil horizon sampling analysis working accuracy is improved.

Description

technical field [0001] The invention relates to a non-cohesive soil sampling device, which belongs to the technical field of soft and low-cohesion soil layer sampling equipment. Background technique [0002] Fly ash and coal gangue solid waste generated during the operation of thermal power plants and coal mines are often used to fill subsidence areas of coal mines, and the surface is covered with soil and then the land is reclaimed. In order to understand the changes in the physical and chemical properties of the filling material and soil layer in the subsidence area, it is necessary to conduct section sampling, and then perform physical and chemical analysis on the samples taken out layer by layer with the sampling shovel. Because the fly ash and coal gangue weathering filling layer is relatively soft and has low cohesiveness, and the existing sampler has a simple structure, most of which are bottom hinge closed structures, during the lifting process, the samples in the sa...
