Sampling device for coal detection

The utility model discloses a sampling device for coal detection, which relates to the technical field of coal sampling and comprises a protective cylinder with a partition plate on the inner wall and a sampling mechanism, and the sampling mechanism is arranged in the protective cylinder and comprises a driving component, a sampling component and a threaded cylinder. According to the sampling device for coal detection, a telescopic air cylinder is driven to drive a pushing rod to move upwards, and under the action of a sliding block and a sliding groove, two moving plates drive two opening and closing plates to get close to each other, so that the bottom of a sampling frame is closed, and the situation that after coal is collected, part of coal falls off from the coal sampling device, and coal sampling is affected can be prevented; according to the sampling device for coal detection, by driving the rotating motor, the rotating shaft and the small gear are rotated, the small gear is meshed with the large gear,
