Abstract

The utility model discloses a traction coal mining machine capable of climbing a soleplate chain, comprising a machine body and a traction device. The machine body is provided with a bottom bracket, a supporting beam, an electric device, a hydraulic device and a cutting part; the traction device is an external type and arranged at one side outside of the machine body; the traction device comprises a left driving device, a right driving device and a chain; the driving device is fixedly connected with the side of a transmission machine by a connection frame; the driving device is provided with a chain wheel; the chain wheels of the left driving device and the right driving device are connected with each other by the chain; two ends of the chain are connected with the machine body which is a front-convex type; a sliding shoe which is arranged at one side of the machine body is overlapped to the ramp plate of the transmission machine and the other side thereof is overlapped to the guide pipe of the transmission machine; and the bottom of the bottom bracket at one side of the cutting part is provided with the supporting beam. The utility model has low height of the machine body, is suitable for mining the thin coal layers of 0.85-1.3 meters, and the whole machine runs stably and has low failure rate.

Description

Climb the base plate chain hauled shearer

Technical field

The utility model belongs to the coal-winning machine technical field, especially relates to a kind of low seam mining machinery tool under the coal mine that is used for.

Background technology

China's girdle reserves are abundant, account for more than 20% of whole yields, because be subjected to effects limit such as work plane condition, space are narrow and small, girdle belongs to difficult mined bed, existing coal mine section chief's arm fully-mechanized mining equipment, coal-winning machine is positioned on the conveyer, with the conveyer is orbit, and coal-winning machine adopts chainless haulage, and its traction wheel engagement conveyer pin rail advances, the fuselage height is not suitable for thin seam mining; Shortcomings such as the off pan shearer that also has though effectively reduce the fuselage height, exists fluctuation of service, and fault rate is low.

Summary of the invention

The technical problems to be solved in the utility model provides and a kind ofly is applicable to gentle dip girdle mechanization work face, and operates steadily the coal-winning machine that fault rate is low.

For solving the problems of the technologies described above, the utility model comprises body and draw-gear, body is provided with bottom bracket, brace summer, electric installation, hydraulic means and cutting units, its design feature is that draw-gear is an external, be located at a side of engine body exterior, it comprises a left side, right drive unit and chain, drive unit connects with the conveyer sidepiece is fastening by link, drive unit is provided with sprocket wheel, a left side, connect by chain between the sprocket wheel on the right drive unit, the chain two ends are connected with body, body is the lordosis formula, the piston shoes of body one side and conveyer ramp plate overlap joint, opposite side are by connector and conveyor guide pipe overlap joint, and the bottom bracket bottom of cutting units one side is provided with brace summer.

Described drive unit comprises motor, intermediate gearbox, slip electromagnetic clutch, link, hydraulic cylinder and sprocket wheel.

The chain two ends are connected with the chain hook of body.

The beneficial effects of the utility model are: owing to be provided with external chain haulage device, its drive unit and haulage chain are located at body one side, body is the lordosis formula, and the fuselage main body is located at the transporter side, protrudes into the coal seam, the fuselage height has obtained effective reduction, can be suitable for working thickness and be 0.85 to 1.3 meter girdle, two drive units carried out back production by the chain traction body about draw-gear was provided with, complete machine operates steadily, and fault rate is low.
