Digging device of mine digging type loader

Abstract

The invention discloses a digging device of a mine digging type loader. The digging device comprises a base, a big arm base, a big arm, a big arm oil cylinder, a small arm, a small arm oil cylinder, an excavator bucket, an excavator bucket oil cylinder, a middle arm and a middle arm oil cylinder, wherein the middle arm and the middle arm oil cylinder are arranged between the big arm and the small arm, the rear end of the middle arm oil cylinder is hinged with the front end of the big arm through a pin roll, the front end of the middle arm oil cylinder is hinged with the rear end of the small arm through a pin roll, the middle arm oil cylinder is arranged between the middle arm and the big arm, the small arm oil cylinder is arranged between the middle arm and the small arm, one end of the middle arm oil cylinder is connected with the big arm through a pin roll, the other end of the middle arm oil cylinder is connected with the big arm through a pin roll, one end of the small arm oil cylinder is connected with the middle arm through a pin roll, and the other end of the small arm oil cylinder is connected with the middle arm and the small arm through pin rolls. By adopting the technical scheme provided by the invention, the digging distance of the mine digging type loader is increased, the rotation range is enlarged, the digging height is increased, no dead angle is remained in slagging-off and cleaning work, most of places in a tunnel can be dug, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a mining digging loader. Background technique [0002] With the continuous development of engineering technology, a large number of special equipment suitable for different industrial and mining conditions have emerged. The mining backhoe loader is a high-efficiency mining equipment for continuous production. Commonly used backhoe loaders rely on crawler belts to excavate rocks and send them to the tail of the transport tank by their own conveying mechanism, and then fall into the transport vehicle parked below the tail of the transport tank. The rock at the place can also be cleaned with a bucket. The working mechanism of this mining excavator loader is mainly composed of a rotary cylinder, a boom, a boom cylinder, a small arm, a small arm cylinder, a bucket, a bucket cylinder and other components. Composition, controlling the expansion and contraction of the rot...
