Abstract

The invention discloses a heading machine suitable for a small-section tunnel. A conveyor is arranged on the side portion of a machine body, and star wheel assemblies are arranged on a shovel plate, so that materials on the shovel plate can be pushed by the star wheel assemblies to move from the side portion of the shovel plate into a feeding port of the conveyor, the materials are discharged from one side of the shovel plate, and then the materials are discharged through the conveyor located on the side portion of the machine body. Therefore, according to the heading machine, through the design of the star wheel assemblies located on the shovel plate and the conveyor located on the side portion of the machine body, the mode that an existing heading machine discharges materials through two star wheel assemblies can be replaced, the overall structure of the heading machine is compact, the width of the whole heading machine is reduced, and the heading machine is suitable for cutting hard rock in a small section.

Description

technical field [0001] The invention belongs to the technical field of roadheaders, and in particular relates to a roadheader suitable for small-section tunnels. Background technique [0002] The excavation process of small-section tunnels in the prior art generally adopts excavation by blasting, excavator or roadheader. Among them, blasting is high in risk and low in efficiency; the efficiency of excavator is extremely low and cannot meet the requirements of work efficiency; The construction work efficiency is high, safe and reliable, but due to the size of the body, the existing roadheader cannot operate on small sections such as water conservancy and power tunnel construction below 2.5 meters (width), so it is difficult for the roadheader to operate on small sections High, even can not work in a small section; and because the general power tunnels pass through cities, highways and other important public buildings underground, therefore, it is impossible to implement blast...
