Abstract

The invention discloses a mechanical drive dual-disc development device for a development machine, which consists of development heads, a development arm and a drive mechanism, wherein the development arm is arranged on a supporting mechanism; one end of the development arm is connected with the development heads by a diverter, and the other end of the development arm is connected with the drive mechanism by a universal coupling; the drive mechanism consists of a motor, a speed reducer and a drive shaft; and a hydraulic cylinder is also arranged on the supporting mechanism, and is connected with the development arm. The dual-disc development device adopts a unique design, realizes the mechanical drive of the development heads, has stable working performance and improves the development efficiency by over 50 percent.

Description

technical field [0001] The invention relates to a tunneling device, in particular to a mechanically driven double-disk tunneling device for a small tunneling machine. Background technique [0002] Small roadheader is an excavation equipment that integrates cutting, loading and transporting gravel. It is widely used in transportation, tunnels, mining and other fields. Compared with large roadheaders, it has the characteristics of small size and light weight. It is suitable for Medium and small coal mine operations, improve the level of mechanization. Existing small-scale roadheaders all adopt the setting method of hydraulically driving a single heading head. This setting method generally has the following disadvantages: First, the work efficiency is relatively low, and the hydraulic oil consumption is relatively large. Continuous operation for a long time will make the hydraulic power Unstable, not conducive to continuous mining mining. Second, the structural setting of the...
