Crushing and excavation integral type backhoe loader

Abstract

The invention discloses a crushing and excavation integral type backhoe loader, which comprises a main machine of the backhoe loader, wherein the main machine of the backhoe loader is provided with a rotating device, the rotating device is connected with the main machine of the backhoe loader through a gantry frame, one end, away from the main machine of the backhoe loader, of the rotating device is further connected with a telescopic device, one end, away from the rotating device, of the telescopic device is further provided with a crushing hammer, the crushing hammer is further movably connected with an excavation bucket, the rotating device comprises a rotary arm, a large arm seat and a slewing bearing, the rotary arm is connected with the gantry frame, the large arm seat is connected with the telescopic device, and the slewing bearing is connected with the large arm seat and the rotary arm, and is used for driving the large arm seat to rotate by 360 degrees relative to the gantry frame. The backhoe loader has the advantages that a tunnel can be crushed, excavated and loaded at one time, and the open crushing and loading can be completed at one time; explosives are not needed, the number of professional persons is reduced, and the occupation diseases are reduced; in addition, the one-time investment is saved, and the use cost is reduced.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and relates to a digging-breaking integrated digging loader. Background technique [0002] In the existing tunnel construction methods for mining, water conservancy, and hydropower, the drilling and blasting method and the tunnel boring machine method are mostly used. Due to the requirements for the management of explosives in recent years, the increase in labor costs, and the frequent occurrence of occupational diseases, the drilling and blasting method has a great impact on construction. Due to the requirement of standardized management by the unit, many units have not obtained the approval of explosives, and it is difficult to allocate professional construction personnel, which affects the progress of the project, and eventually leads to the shutdown of the project, causing huge losses to individuals, units and the country; the roadheader method is better than one-time The investment is ...
