Description

Double-section arm frame and dredging device for mine Technical Field The utility model relates to the field of mining apparatuses, in particular to a double-section arm frame and a mine dredging device. Background The mine is a roadway which is downwards slipped by the dead weight of the ore, and the operation of a mine field is seriously affected when the mine is blocked. The current methods for treating the blockage of the mine mainly comprise a mechanical prying method, a drilling blasting method, a bamboo pole overhanging explosive blasting method, a hydrogen balloon hanging explosive blasting method, a mine rocket projectile and the like. For the bamboo pole overhanging explosive charge blasting method, an unmanned carrier vehicle with a mechanical gripper mechanism is often adopted to transport the explosive to a proper blasting position, for example, an explosion mine safety dredging moving device disclosed in application number 202510866337.9 is adopted, after the unmanned carrier vehicle arrives at the position, the telescopic rod is clamped by the gripper mechanism, the explosive is fixed at the top of the telescopic rod, so that the explosive is moved to the blasting position for blasting, and the gripper mechanism of the dredging device lacks a flexible multi-angle mechanical arm, so that the dredging device is difficult to adapt to complex throwing angles when the explosive is thrown. Disclosure of utility model The utility model aims to provide a double-section arm frame and a dredging device for a mine, which solve the problem that the conventional dredging device lacks a multi-angle flexible mechanical arm. The utility model realizes the above purpose through the following technical scheme: The double-section arm frame comprises a large arm assembly, a small arm assembly and a handle mechanism, wherein the small arm assembly is arranged at the end part of the large arm assembly, and the large arm assembly and the small arm assembly are respectively provided with a pitching adjusting structure rotating along a horizontal shaft and a turning adjusting structure rotating along a vertical shaft; the pitching adjusting structure of the small arm assembly comprises a first overturning platform arranged on the large arm assembly, the rotation adjusting structure of the small arm assembly comprises a second rotating platform arranged on the first overturning platform, the small arm assembly is arranged on the second rotating platform, the small arm assembly is controlled to pitch and rotate through the first overturning platform and the second rotating platform, and the second rotating platform enables the small arm assembly to rotate above the large arm assembly when the small arm assembly is not used, so that occupied space in the length direction can be reduced. As a preferable scheme of the utility model, the rotation adjusting structure of the large arm assembly comprises a first rotation platform, the pitching adjusting structure comprises a hydraulic cylinder, one end of the large arm assembly is hinged with the first rotation platform, one end of the hydraulic cylinder is hinged on the first rotation platform, and the other end of the hydraulic cylinder is hinged on the large arm assembly.
