[0002] A coal mine is a reasonable space excavated by humans when they dig geological strata rich in coal. It usually includes tunnels, shafts, and mining faces, etc. Coal is the most important solid fuel and a type of combustible organic rock. It is formed by lush plants that grow in a certain geological age. In a suitable geological environment, it gradually accumulates into thick layers and is buried under water or in mud. It is formed by natural coalification over a long geological period.

[0003] Existing conventional sampling devices generally require manual assistance when sampling. The sampling operation is performed after the sampler has descended to a specified depth through manual judgment. When sampling at multiple different depths, manual repeated operations are required, resulting in poor sampling continuity and low sampling efficiency. Summary of the invention

[0014] A threaded hole is provided on the top of the lifting circular plate and is rotatably matched with the thread of the threaded rod.

[0015] The present invention is further configured such that a limiting plate is fixed between the support top plate and the support ring.

[0016] The top of the lifting circular plate is provided with a second rectangular hole which is slidably matched with the limiting plate up and down.

The elastic spring fixedly connected between the sampling shovel and the center column is stretched, and when the sampling shovel passes through the sampling hole until the sampling shovel rotates to the maximum angle, the elastic spring will provide an energy to the sampling shovel. The force of clockwise rotation makes the sampling shovel rotate clockwise on the inner wall of the sampling box with the sampling axis as the center, and the arc-shaped teeth and the sampling axis rotate clockwise until the arc-shaped teeth are meshed with the transmission gear ring again, thereby realizing the counterclockwise-clockwise cyclic rotation movement of the sampling shovel with the sampling axis as the center, and achieving continuous and automatic sampling in the process of the sampling shovel passing through several sampling holes opened on the side surfaces of the sampling box. As the sampling component continuously changes the downward movement depth, rapid and continuous sampling of coal fields at different depths is realized, without the need for manual auxiliary operation, with flexible and convenient use, higher sampling efficiency and more accurate sampling.

[0022] 2. The present invention starts the servo motor fixedly installed on the outer top of the support ring, so that the threaded rod fixedly connected to the output end of the servo motor rotates at the bottom of the support top plate, driving the lifting circular plate that is matched with the rotation of the threads on the peripheral side of the threaded rod to move downward along the direction of the threaded rod between the support ring and the support top plate, driving the sampling assembly to move toward the bottom of the coal field, and causing the drill bit fixedly installed on the outer bottom of the sampling box to move deep into the coal field, which is convenient for subsequent sampling.
