Heading machine

Abstract

The invention provides a heading machine, and belongs to the technical field of engineering machinery manufacturing. The heading machine comprises a cutting part, a shovel plate part, a body part anda walking part, wherein the walking part is positioned the bottom of the body part and is connected with the body part; a rotary table is arranged on the body part; the cutting part is connected withthe rotary table and extends in a direction far away from the rotary table; the shovel plate part is connected with the bottom of the body part, and is positioned under the cutting part; the cutting part comprises a driving device, an elastic shaft coupler, a speed reducer and a cutting head; the driving device is in transmission connection with the input end of the speed reducer through the elastic shaft coupler; the output end of the speed reducer is connected with one end of the cutting head; and the driving device is connected with the rotary table and is used for driving the cutting headto do circumferential rotation. The invention aims at providing the heading machine with the advantages that the impact of high-hardness rock on the cutting part in the cutting operation process of the heading machine can be reduced; the damage probability of the cutting part is reduced; and the service life of the heading machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of engineering machinery manufacturing, in particular to a roadheader. Background technique [0002] In the construction of coal mines, road tunnels, metal mines, railway tunnels, subways, etc., roadheaders are widely used because they can cut and transport materials. [0003] However, the cutting ability of the common roadheader is relatively poor at present. When cutting and breaking rocks with relatively high hardness, the cutting part of the roadheader is usually damaged due to relatively large impact force. Therefore, the existing roadheader cannot be applied to water conservancy tunnels and other roadway sections with relatively small sections and relatively high rock hardness. Contents of the invention [0004] The purpose of the present invention is to provide a roadheader, which can reduce the impact of high hardness rock on the cutting part during the cutting operation of the roadheader, reduce ...

Problems solved by technology

[0003] However, the cutting ability of common roadheaders is relatively poor at present. When cutting and breaking rocks with relatively high hardness, due to the relatively large impact force, the cutting part of the roadheader will usually be damaged.

Therefore, the existing roadheaders cannot be used in water conservancy tunnels and other working conditions where the roadway section is small and the rock hardness is high.
