Abstract

The invention discloses a cutting head for a heading machine and the heading machine. The cutting head comprises a cutting head body, wherein a plurality of cutting blades are fixedly mounted on the surface of the cutting head body; a limiting pipe is arranged on one side of the cutting head body; limiting plates are fixedly mounted at the upper and lower ends and the front and rear ends of one side of the cutting head body; one side of each limiting plate penetrates through the limiting pipe and extends to an inner cavity of the limiting pipe; a supporting plate is fixedly mounted in the inner cavity of the limiting pipe and is positioned on the outer side of the limiting plate; a supporting plate is fixedly mounted in the inner cavity of the limiting pipe and is positioned on the inner side of the limiting plate; when the cutting blades are greatly abraded and need to be replaced, a motor is started, an output shaft of the motor drives a first gear to rotate, the first gear drives a second gear to rotate, the second gear drives a threaded rod to rotate, and the threaded rod drives a moving rod to move; and when the moving rod is separated from a clamping state with the limiting plate, the motor is stopped, the cutting head is taken out and replaced with a new cutting head, and the replacement efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of roadheaders, and in particular relates to a cutting head for a roadheader and a roadheader. Background technique [0002] The roadheader is a machine used to excavate roadways on flat ground. There are many types of roadheaders: ordinary machines and tunnel boring machines according to the operating objects; open type roadheaders and shield type roadheaders according to the operation method. The working method: It is mainly composed of a traveling mechanism, a working mechanism, a loading mechanism and a reloading mechanism. As the traveling mechanism advances, the cutting head in the working mechanism continuously breaks rocks and transports the broken rock away, which has the advantages of safety, high efficiency and good roadway quality. Advantages, but the cost is high, the structure is complicated, and the loss is also large. [0003] However, in existing coal mine roadheaders, the cutting head is n...
