Abstract

The invention discloses a detachable coal seam gas coal core sampling machine. The sampling machine comprises a bottom plate, two walking positioning devices and a sampling device; the two walking positioning devices are arranged on the bottom plate; the two walking positioning devices are symmetrically mounted on the left side and the right side of the lower end of the bottom plate; an opening structure is formed in the middle of the right side of the upper end of the bottom plate; the sampling device is mounted on the left side of the upper end of the bottom plate; and the right side of thesampling device is located in the opening structure. According to the sampling machine, the difficult problems that during underground coal seam gas sampling, an existing sampling machine is inconvenient to move, poor in positioning effect, inaccurate in coal seam sampling, complex in sampling, inconvenient in operation, low in automation degree and low in working efficiency, and after sampling, the existing sampling machine cannot quickly take out coal cores in the sampling machine and effectively distinguish the coal cores, and is complex in operation, high in labor intensity and low in efficiency, and the like can be solved, so that the function of automatic quick sampling of underground coal seam can be realized.

Description

technical field

[0001] The invention relates to the field of sampling machine equipment, in particular to a detachable coal bed gas coal core sampling machine. Background technique

[0002] Layered solid combustible minerals transformed from plant remains through complex biochemical and geological processes. It occurs in coal-bearing rock series, located between the roof and floor rocks. The number of layers, thickness, occurrence and burial depth of coal seams are restricted by paleostructure, paleogeography and paleoclimate conditions. The occurrence of coal seams is an important basis for determining the economic value of coal fields and development planning; coal seams need to be sampled before mining.

[0003] The existing sampling machine is inconvenient to move when sampling the underground coal seam, the positioning effect is poor, and the coal seam cannot be sampled accurately. The coal core in the sampling machine is taken out, and the coal core cannot be effect...
