Technical Field

[0001] The utility model relates to a deep sampling device for coal mine geological exploration, specifically a deep sampling device for coal mine geological exploration, belonging to the technical field of deep sampling devices for coal mines. Background Technique

[0002] The deep sampling device for coal mine geological exploration is an important device in the field of geological exploration, specifically used to collect deep samples from coal mine strata for subsequent geological analysis and research.

[0003] The deep sampling device for coal mine geological exploration usually includes multiple components, such as drill tools, sampling cylinders, power systems, etc., which work together to achieve the collection of deep samples.

[0004] In the prior art, a drilling bit is installed at one end of the drill pipe, and a drilling connection seat is connected at the other end. The drill pipe is connected to the drive system through the drilling connection seat. The drive system drives the drill pipe to drill holes. By continuously splicing the drill pipes, the drilling bit drills to a suitable position in the coal mine, and then the sampling device is installed to take samples from the coal mine. However, in the prior art when taking samples, it is necessary to first install a connector to remove the coal in the drill pipe, and then install the sampling device to take samples from the coal mine. It requires multiple tool replacements. At the same time, when taking samples from the coal mine, it is necessary to repeatedly extract during the removal and sampling of the coal mine, resulting in a relatively long sampling time consumption and being not conducive to the deep sampling efficiency. Therefore, we propose a deep sampling device for coal mine geological exploration. Content of the Utility Model

The sealing seat 403 seals the sampling seat 2 and the collecting frame 401. First, the coal mine is drawn through the air inlet to remove the coal mine in the drill pipe 1. After the drawing is completed, the connecting threaded rod 402 is rotated to drive the sealing seat 403 to move away from the sampling rod 3, and then the coal mine can be sampled, so that the coal mine is stored in the collecting frame 401. After the sampling is completed, the collecting frame 401 is sealed by the sealing seat 403, and the storage of the coal mine sample is completed, which is convenient to sample at a designated position and avoids the cumbersome process of sampling the coal mine by replacing multiple instruments.
