Problems solved by technology

[0002] During the use of the current lifting arm, because the weight and quantity of the ore are different, the length of the force arm required is also different. At the same time, if the lifting arm or the mining machine is replaced, it will waste manpower and material resources. For this reason, we disclose a mining machine with lift arm

Embodiment approach

[0025] As another embodiment of the invention, a mounting rod 12 is vertically slidably installed on the side of the mounting plate 1 far away from the first rotating rod 6, and a plurality of first engagement grooves are provided on the mounting rod 12 along the sliding direction of the mounting plate 1, and the installation The plate 1 is provided with a second clamping groove which can communicate with the first clamping groove, and a detent pin can be clamped in the first clamping groove and the second clamping groove. The mounting plate 1 slides vertically on the mounting rod 12, thereby adjusting the height of the entire lifting arm to meet different installation requirements; In the second clamping slot, the position between the mounting plate 1 and the mounting rod 12 is fixed.

[0026] As another embodiment of the invention, the end of the crowbar 3 away from the hydraulic cylinder 9 is provided with a mounting docking block 13 , and a plurality of mounting holes are ...

Abstract

The invention relates to the technical field of lifting arms, and discloses a lifting arm for a mining machine, which comprises a mounting plate, a supporting piece is rotatably mounted at one end of the mounting plate, a sliding block is rotatably connected to the other end of the supporting piece, a pinch bar is slidably mounted outside the sliding block, and a driving piece for driving one end of the pinch bar to move up and down is arranged on the mounting plate. According to the lifting arm for the mining machine, the length of a force arm of the lifting arm can be conveniently adjusted, meanwhile, it is guaranteed that the linear distance from a supporting point to a driving point cannot be changed, position adjustment of a driving piece is reduced, the installation height of the whole lifting arm can be adjusted, and the lifting arm is high in applicability and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of lifting arms, in particular to a lifting arm for a mining machine. Background technique [0002] During the use of the current lifting arm, because the weight and quantity of the ore are different, the length of the force arm required is also different. At the same time, if the lifting arm or the mining machine is replaced, it will waste manpower and material resources. For this reason, we have disclosed a mining machine Use the lift arm. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a lifting arm for a mining machine. [0004] A lifting arm for a mining machine, comprising a mounting plate, one end of the mounting plate is rotatably mounted with a support, the other end of the support is rotatably connected with a slider, and a pry bar is slidably installed outside the slider, the The mounting plate is provided...
