Abstract

The invention relates to a diggingbolt group cutting device, in particular to a speed reducer of the diggingbolt group cutting device to solve the problems of the defects of a cutting speed reducer in an existing cutting device. The speed reducer structurally comprises an upper shell, a lower shell, a left supporting shell, a right supporting shell, an upper gear case, a lower gear case, a left planetary gear case, a right planetary gear case, cutting blocks, a cutting gland, a left supporting shell gland, a right supporting shell gland, a five-level left planet carrier, a five-level right planet carrier and hubs. A left power input bevel gear shaft and a right power input bevel gear shaft are connected with the left planetary gear case and the right planetary gear case through a driven bevel gear, a spline shaft drive helical gear and a transmission shaft respectively. Cutting rollers are connected to the two sides of the left planetary gear case and the right planetary gear case to form double-motor drive, an overall-width cutting mechanism of a diggingbolt group is more stable and reliable in work, the technical support is provided for mining machine serialization development in China, the technical reserve is provided for heavy tunneling devices, and the technological level of the coal mine tunnel tunneling device field in China is improved.

Description

technical field [0001] The invention relates to a cutting device of a bolter digging unit, in particular to a speed reducer of the cutting device of a bolter digging unit. Background technique [0002] In coal mine underground mining equipment, the bolter digging unit relies on the full-width cutting device to realize the tunneling and forming at one time. The cutting device is the most important core working part of the whole machine. Driven by a motor, the cutting width is large, up to 5-6m, the cutting capacity is strong, and the production efficiency is high. It has many advantages over the longitudinal axis cutting device and the short horizontal axis cutting device. [0003] The cutting device of the bolter mining unit mainly includes a cutting reducer, a telescopic drum, and a cutting motor. When the bolter unit is working, the cutting device moves to the designated position, the cutting motor is started, and the cutting drum is extended to the width of the roadway t...
