Description

Geological field grooving sampling equipment Technical Field The invention relates to the technical field of rock sampling equipment, in particular to geological field grooving sampling equipment. Background The geological field grooving sampling equipment is used for carrying out geological mineral exploration on the surfaces of geological bodies such as field geological outcrops, exploring grooves and tunnels, and is characterized in that key indexes such as chemical components, mineral compositions, grades, resource reserves and the like of the mineral bodies or the geological bodies are determined through laboratory analysis and test, so that real and reliable basic data support is provided for mineral resource exploration evaluation, reserve estimation, exploitation planning and geological scientific research work. For example, patent document CN114544220B discloses a geological tunnel grooving sampling device, which cuts two parallel grooves through the combined structure of two cutting bits and a diamond cutting line, and then cuts the middle rock body by using the diamond cutting line in a reciprocating manner, so that a complete rock spline can be obtained at one time, the problem of breaking and breaking the rock in the traditional sampling is avoided, and the device is beneficial to the subsequent geological investigation. Meanwhile, the sliding support table and the telescopic support rod are arranged, a manual whole-process holding device is not needed, the labor consumption is greatly saved, the geologic bodies with different heights and inclination angles can be adapted by adjusting the length of the telescopic support rod and the cooperation of the arc-shaped sliding sleeve, and the application scene is more flexible. The cutting drill bit is detachably connected with the gear connecting seat through the rectangular inserting shaft, so that the worn parts can be replaced conveniently, and the two sides of the machine body are provided with the operating handles, so that the manual pushing of the adjusting position is facilitated. The sliding support is provided with a protection cutting, can be clung to the rock body to block the cut spline, prevents the spline from falling off and breaking due to vibration or gravity, and further ensures the integrity of the spline. However, in practical use, the device has the defects that 1) the long-distance sampling flexibility is poor, if the length of a mine hole is long, the position of the bracket needs to be disassembled and adjusted for many times due to the fact that the fixed length of the sliding bracket (1.2 m in the embodiment), the operation is complex, the efficiency is low, 2) the secondary cutting operation is complex, if the cutting depth needs to be deepened or the cutting specification needs to be adjusted, the cutting part needs to be disassembled and replaced again or the bracket parameters need to be adjusted again, the secondary cutting cannot be realized quickly, the convenience of adapting to different sampling requirements is not enough, 3) a sundry cleaning mechanism is lacked, broken stones and dust in the mine hole are easily accumulated on the sliding bracket or a track, a special cleaning device is not designed, the sliding precision of a machine body is possibly influenced, and even the device is blocked. 4) The moving and installing convenience is not enough, the combination of the sliding support table and the telescopic support bar can adjust the angle, but the overall disassembly, transportation and installation processes are complicated, and the flexibility is poor especially when moving in a mine tunnel in complex terrains. Disclosure of Invention The invention provides geological field grooving sampling equipment, which aims to solve the technical problems that the grooving sampling equipment in the prior art has poor long-distance adjusting effect, cannot be used for quick secondary cutting and is inconvenient for cleaning sundries. In order to solve the problems, the geological field grooving sampling equipment provided by the invention adopts the following technical scheme: A geological field notch sampling device comprising: A support rail for laying on a sampling surface within the mine cavity for defining a cutting stroke; A mobile cutting assembly, guidingly arranged on said support rail for movement along the support rail within a defined cutting stroke, the mobile cutting assembly comprising cutting elements of at least two dimensions to adapt to different cutting requirements; a discharging assembly arranged on the movable cutting assembly for cleaning sundries located on the supporting guide rail along with the movement of the movable cutting assembly; and the supporting guide rail is also provided with a discharging channel which is used for discharging sundries cleaned by the discharging assembly. The mining device has the advantages that the supporting guide rail can be directly paved on a sampling sur
