When the grinding equipment shell 1 rotates due to external driving to perform grinding work of cement clinker, the cement clinker in the grinding equipment shell 1 can be uniformly distributed due to the centrifugal force generated by the rotation of the grinding equipment shell 1. When the hatch cover 2 moves to the position corresponding to the material receiving base 3 and material taking work is needed, the first air cylinder 42 operates to push the limiting plate 43 to move upwards to a proper height, and when the roller 411 contacts with the limiting plate 43 and is stressed, the pushing plate 41 can be driven to move upwards to drive the hatch door 21 to move outwards to open, so that cement clinker in the grinding equipment shell 1 falls into the material receiving box 32 through the material receiving base 3 and the material receiving opening 31 in sequence to finish sampling work.
When the material taking work is carried out, the cabin door 21 can be opened to finish sampling under the condition of not stopping the machine, so that the production efficiency of the equipment is not affected. In the sampling process, as the grinding equipment shell 1 is in a non-stop running state, the cement clinker can be uniformly distributed in the grinding equipment shell 1 under the action of centrifugal force generated by the grinding equipment shell 1, so that the obtained sample is more representative and the subsequent detection precision is improved.
