The invention provides a handheld pneumatic drill sampling device. The sampling device is a hollow barrel, wherein the outer surface of the hollow barrel is provided with threaded grooves, the front end of the hollow barrel is provided with drill bit cutting teeth along the circumferential direction of the hollow barrel, the rear end of the hollow barrel is closed and is provided with a connecting part, and the connecting part is matched with a handheld pneumatic drill bit joint. By adopting the handheld pneumatic drill sampling device, the problem that the existing sampling device is not ideal in sampling effect and likely to have a measurement error can be solved.
Description
technical field [0001] The invention belongs to the field of samplers, in particular to a hand-held pneumatic drill sampler. Background technique [0002] The excavation face adopts comprehensive mechanized excavation. During the excavation process, due to the high gas content, some areas reach the critical value of the gas threat area, and it is often necessary to measure the gas content. In coal mine gas content measurement work, taking coal samples underground has always been a technical difficulty. The existing equipment is often in the sampling process. Because the sampler and the drill pipe are connected by threads, the drilling rig cannot be reversed when the drill pipe is stuck. Successful sampling will affect the successful completion of the content determination work. Contents of the invention [0003] The invention provides a hand-held pneumatic drill sampler, which solves the problem that the existing sampling equipment cannot be reversed when the drill is stu...
