Rock arm for rock crushing

Abstract

The invention discloses a rock arm for rock crushing. The rock arm comprises an excavator body, a big arm, a small arm, a big arm oil cylinder, a small arm oil cylinder and a digging bucket of the excavator body are taken down and not used, the rock arm further comprises a supporting big arm oil cylinder, a rock crushing front arm oil cylinder, a supporting big arm, a rock crushing front arm and adiamond cutter head, wherein the supporting big arm oil cylinder, the rock crushing front arm oil cylinder, the supporting big arm and the rock crushing front arm are connected through pin shafts, and the diamond cutter head is mounted at the lower end of the rock crushing front arm. According to the rock arm for rock crushing, an existing excavator is adopted as a carrier, investment is low, working is reliable, and using is convenient. When the rock arm is used, an operator controls the diamond cutter head at the lower end of the rock crushing front arm to quickly fall from the high position to act on rock, and then the rock crushing effect can be achieved; and because the weight of the rock crushing front arm is large, during operation, under action of the weight of the rock crushing front arm, downward-moving potential energy of the rock crushing front arm and double acting force of the diamond cutter head, the rock can be effectively disintegrated and crushed. Base on the above,The rock arm for rock crushing has good application prospects.

Description

technical field [0001] The invention relates to the field of construction machinery equipment, in particular to a rock arm for rock breaking. Background technique [0002] Rock crushing is a process that often needs to be carried out in engineering construction and mining operations; relevant equipment is required during construction to separate part of the rock mass from the parent body and break it to facilitate loading and unloading of the project, loading and unloading of transfer equipment (including transfer vehicles and loading and unloading vehicles). In the prior art, explosive blasting and mechanical crushing are often used to crush large-volume rocks. Among them, although explosive blasting has high rock crushing efficiency, the partial crushing effect is not complete, and secondary crushing is required for large rocks after blasting. More importantly, due to the large impact of blasting on the surrounding environment, it may damage buildings, people and animals. ...

Problems solved by technology

Among them, although explosive blasting has high rock crushing efficiency, the partial crushing effect is not complete, and secondary crushing is required for large rocks after blasting. More importantly, due to the large impact of blasting on the surrounding environment, it may damage buildings, people and animals. It is forbidden to use in areas that bring potential safety hazards and areas with high geological structure requirements, and the scope of application is small.

Mechanical crushing is widely used because of its high safety characteristics; the existing mechanical rock crushing methods mainly rely on hydraulic breakers and high-frequency breakers carried by excavators to break rocks. In the actual rock breaking process, Due to the lack of gravity of the hydraulic breaker and high-frequency breaker, the force acting on the rock is small, so the rock breaking speed is slow, resulting in low work efficiency and affecting the construction progress
