Problems solved by technology

[0003] In addition, the existing mining scraper excavator adopts a two-arm hinge mechanism. Due to the limitation of underground space, the joint points of the excavator arm are easy to touch the roof of the roadway or the anchor rod and anchor cable, which reduces the safety factor of mine construction.
During the construction process of the excavator, there are often construction dead spots on both sides of the excavator, which are often repaired by moving or retreating the excavator, or by manually stacking them together. Repeated construction wastes manpower, material and financial resources

Abstract

The invention discloses a mining scraper type electric hydraulic excavator. The excavator comprises a big arm (4) arranged on an upper frame of the excavator, the big arm (4) is connected with an auxiliary arm (2), the auxiliary arm (2) is internally provided with a rotary oil cylinder (3), and the auxiliary arm (2) is connected with a small arm (1); and the excavator is further comprises a scraper conveyer belt (8) arranged in a cavity of a chassis of the excavator in a penetrating mode, and a bucket (14) is arranged at the front end of the scraper conveyer belt (8). According to the excavator, the requirements of flexible, efficient and multi-working-condition operation of the mining excavator are met, no construction dead angle is left, the performance is reliable, the applicability ishigh, the working efficiency and the operation safety of the mining excavator are greatly improved, and the labor intensity is remarkably reduced.

Description

technical field [0001] The invention relates to a hydraulic excavator, in particular to a mining scraper type electric hydraulic excavator. Background technique [0002] The scraper conveyor belt and the fuselage of the existing mining scraper excavator are integral, the scraper conveyor belt is installed on the fuselage, the fuselage and the chassis are relatively fixed, and the workbench cannot rotate independently. The operating arm can only rotate within the range of ±40°~±60° included angle. [0003] In addition, the existing mining scraper excavator uses a two-arm hinge mechanism. Due to the limitation of underground space, the joint points of the excavator arm are easy to touch the roof of the roadway or the anchor rod and anchor cable, which reduces the safety factor of mine construction. During the construction process of the excavator, there are often construction dead spots on both sides of the excavator, which are often repaired by moving or retreating the excav...
