Abstract
The utility model discloses an excavator for coal mines. The excavator is characterized in that a large arm and a small arm of the excavator can be vertically closed, and the outermost size of the closed large arm (1) and the small arm (2) is smaller than that of a crawler protecting plate (3). Accordingly, the excavator can be conveyed in a vertical shaft with a narrow space, effectively excavates and clears up the bottom of the vertical shaft, reduces operation cost and improves work efficiency.
Description
Technical field
The utility model relates to a kind of colliery excavator, belongs to the technical field of engineering machinery.
Background technology
Existing colliery can not vertically close up with big arm of excavator and forearm and cause and can not transport in the narrow and small vertical shaft in space, thereby can not excavate cleaning effectively to silo bottom, has increased cost, has reduced operating efficiency.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of colliery excavator is provided, can solves excavator effectively because big arm and forearm can not vertically close up and can't enter vertical shaft and silo bottom is excavated effectively shortcomings such as cleaning.
The technical solution of the utility model:
Big arm and forearm can vertically close up, and perpendicular to the crawler belt backplate;
Outermost dimension when big arm and forearm vertically close up is less than the crawler belt backplate.
Compared with prior art, the big arm of excavator can vertically close up with forearm thereby can transport in the narrow and small vertical shaft in space, can excavate cleaning effectively to silo bottom, has reduced job costs, has improved operating efficiency.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment of the present utility model: as shown in Figure 1, the big arm 1 of excavator and forearm 2 can vertically close up and big arm 1 and forearm 2 outermost dimension when vertically closing up makes less than crawler belt backplate 3 and excavates function and transport in the narrow and small vertical shaft in space and then silo bottom is excavated cleaning effectively.
Claims (1)
1. colliery excavator, it comprises fuselage (4), it is characterized in that: big arm (1) and forearm (2) can vertically close up, and perpendicular to crawler belt backplate (3).
2, colliery according to claim 1 excavator is characterized in that: big arm (1) and the outermost dimension of forearm (2) when vertically closing up are less than crawler belt backplate (3).
