Abstract

The invention provides an internal spraying type cutting mechanism for a horizontal-axis roadheader, and belongs to the technical field of the cutting mechanism of the horizontal-axis roadheader. Theinternal spraying type cutting mechanism comprises a cutting arm, a horizontal-axis cutting reducer and cutting rollers which are symmetrically arranged on two sides of the horizontal-axis cutting reducer; a cutting motor is arranged in the cutting arm; the horizontal-axis cutting reducer is arranged at the front end of the cutting arm and comprises a reducer shell, a first helical gear, a secondhelical gear, a first bevel gear, a second bevel gear, a first sun gear, a first planet gear, a first inner gear ring, a first planet carrier, a second sun gear, a second planet gear, a second planetcarrier and a second gear ring. The internal spraying type cutting mechanism for the horizontal-axis roadheader can effectively reduce the risk of pressure water leakage to the reducer, and has a larger transmission ratio.

Description

technical field [0001] The invention belongs to the technical field of a cutting mechanism of a horizontal-axis roadheader, and specifically discloses a cutting mechanism of an inner-spray type horizontal-axis roadheader. Background technique [0002] At present, heavy-duty tunneling equipment should generally be equipped with spray devices during underground cutting operations to achieve the functions of cooling, dust removal, and spark prevention. From the external spray to the current internal spray, the internal spray is more efficient than the external spray in practical application, but the fluid transmission path in the internal spray varies with the internal components of the cutting mechanism. The transmission mode of the cutting mechanism is also closely related to the internal structure, and the position of the nozzle on the cutting drum is also very regulated. The high-efficiency internal spray can cool down the pick in time during the cutting operation, effecti...
