Problems solved by technology
[0002] The rock mass sample size grinder is an instrument used to grind rock mass sample particles in rock mass analysis experiments, but because the existing rock mass sample size grinder cannot accurately screen when grinding rock mass samples, the particle size has passed through After the grinding meets the requirements, it cannot be sorted out in time and continues to participate in the grinding. The high temperature generated during the grinding process will destroy the organic matter in the rock mass sample, which will affect the experimental structure and waste manpower and time.

Embodiment Construction
[0018] In the accompanying drawings, a rock mass sample grinding device includes a housing 4 and an upper cover 2 fitted with the housing 4, and also includes a grinding mechanism located in the housing 4, a driving device for driving the grinding mechanism, and a device. A screening device outside the grinding mechanism; the screening device includes a mesh screen cover 3 , the bottom end of which is connected to a mesh screen seat 7 , and the mesh screen seat 7 is movably connected to the bottom opening of the housing 4 .
[0019] The bottom opening of the mesh screen seat 7 corresponding to the mesh screen cover 3 is a sealed structure.
[0020] When the screening device is connected with the housing 4 , the top of the screen cover 3 is tightly against the upper cover 2 .
[0021] The mesh sizes on the mesh screen cover 3 and the mesh screen seat 7 are the same.
[0022] The grinding mechanism includes a cutter 8 installed on a cutter shaft 5 ;
[0023] The driving device...

The invention relates to a rock body sample grinding device. The rock body sample grinding device comprises a shell and an upper cover assembled on the shell, a grinding mechanism arranged in the shell, a driving device for driving the grinding mechanism to operate as well as a screening device arranged outside the grinding mechanism, wherein the screening device comprises a mesh screen cover; the bottom end of the mesh screen cover is connected with a mesh screen base, and the mesh screen base is movably connected with a bottom port of the shell. The device provided by the invention has the advantages that exact screening is realized, a condition that a rock body sample can be sorted out in time after the particle size reaches the requirement is guaranteed, damage to an organic matter in the rock body sample caused by the operation of continuing to grind is prevented, the precision of an experimental result is not influenced, and the manpower and materiel resource are saved.
Description
technical field [0001] The invention relates to an instrument for precisely grinding rock mass samples in rock mass analysis experiments, in particular to a rock mass sample grinding device, which belongs to the field of experimental instruments. Background technique [0002] The rock mass sample size grinder is an instrument used to grind rock mass sample particles in rock mass analysis experiments, but because the existing rock mass sample size grinder cannot accurately screen when grinding rock mass samples, the particle size has passed through The high temperature generated during the grinding process will destroy the organic matter in the rock mass sample, which will affect the experimental structure and waste manpower and time. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a rock mass sample grinding device, which can realize more accurate screening, ensure that the rock mass sample particles can be sorted out...
