Dual-purpose tunneling loader for breaking and excavating

Abstract

The invention discloses a dual-purpose tunneling loader for breaking and excavating. The dual-purpose tunneling loader is used for breaking, excavating and loading in mine engineering. The dual-purpose tunneling loader is composed of a telescopic breaking and excavating integrated tunneling mechanism, a conveying and unloading mechanism, a crawler chassis, an electrical control system and a hydraulic control system, wherein the conveying and unloading mechanism is mounted at the upper part of the crawler chassis, the telescopic breaking and excavating integrated tunneling mechanism is assembled at the front end of the conveying and unloading mechanism, a bucket and a connecting rod are hinged to the front end of a forearm of the telescopic breaking and excavating integrated tunneling mechanism, a connecting plate is hinged between the connecting rod and the bucket, guide shafts are installed on the two sides of the upper portion of the forearm, sliding rails are installed in the forearm and tightly matched with the guide shafts through notches in the sliding rails, a hydraulic breaking hammer is clamped between the two sliding rails, a bucket oil cylinder and a breaking hammer oilcylinder are both arranged in the forearm. The dual-purpose tunneling loader has the functions of crushing, excavating, scrabbling and loading, hydraulic actuators are controlled through hydraulic pilots, the functions of complete machine walking, crushing, excavating, pushing, shoveling, collecting, excavating, scrabbling, conveying, loading and the like are achieved, and multiple purposes are achieved through the dual-purpose tunneling loader.

Description

technical field [0001] The invention relates to the technical field of mining engineering machinery, in particular to a dual-purpose tunneling loader suitable for mining and tunneling. Background technique [0002] At present, mining and tunneling mainly use blasting or special crushing equipment for excavation, and then transfer the crushed materials. However, as the country's control over explosives becomes more and more stringent, the cost of using blasting is also getting higher and higher. For construction sites where blasting operations are not allowed, special excavation and transfer equipment is required. For construction sites with relatively small mining or tunneling sections, it is relatively difficult to transfer and switch between equipment, which not only delays time, but also increases the input cost of equipment and labor. Therefore, it is very necessary to develop a device integrating crushing, excavation and loading. Contents of the invention [0003] ...
