Abstract

The invention discloses a hook digging rock arm small arm with a material filling mechanism. The hook digging rock arm small arm comprises a left clamping plate, a right clamping plate and a hook digging plate, wherein the left clamping plate and the right clamping plate are arranged side by side; the upper part of the hook digging plate is clamped between the left clamping plate and the right clamping plate; the hook digging plate is detachably connected with the left clamping plate and the right clamping plate; the hook digging plate is of a hollow structure; a filler port is formed in the middle part of one side of the hook digging plate. The problems that the connected structure of an existing hook digging rock arm small arm and a digging hook is complicated and the maintenance cost after the integration of the hook digging rock arm small arm and the digging hook is high are solved, and further, the problem that the weight of the hook digging rock arm small arm is inconvenient to adjust according to the harness condition of rock stratum since the weight of the existing hook digging rock arm small arm is constant is solved, so that the hook digging rock arm small arm has a preferable rock breaking effect.

Description

technical field

[0001] The invention relates to the field of excavating equipment, in particular to a digging hook rock arm forearm with a material filling mechanism. Background technique

[0002] The hook rock arm is usually used for excavating and planing the rock. The forearm of the digging hook rock arm must be connected with the boom and also with the digging hook. Therefore, the structure of the forearm in the prior art is usually more complicated. Although some people try to make the forearm and digging hook into an integrated structure, although this simplifies the structure of the forearm, once the parts responsible for digging and planing are damaged, it needs to be repaired as a whole. Replacement, resulting in high maintenance costs.

[0003] And the weight of the forearm of existing digging hook rock arm is fixed, and like this can not effectively destroy rock face because weight is not enough when facing harder rock face. Contents of the invention [00...
