Explosive and powder reaction kettle sampling observation device

The utility model relates to the field of sampling devices, in particular to an explosive and powder reaction kettle sampling observation device which comprises a box body, a first air cylinder vertically arranged on the box body, a second air cylinder horizontally arranged on the box body and a cover body. The sampler rotates under the action of components such as a second cylinder, a hollow gear and a rack, a cover body is arranged at the sampling port through a flange plate, so that the inside of the reaction kettle is isolated from the outside, and a spoon part of the sampler extends into the reaction kettle from the lower part of the cover body to realize online closed sampling; the sampler moves upwards to drive the cover body to be separated from the flange plate, and samples on the sampler are observed by adjusting rotation, zooming and the like of the anti-explosion zoom camera, so that man-machine isolation of granularity observation is realized. According to the utility model, personnel can be free
