FIELD: scraper conveyors.
SUBSTANCE: drive system comprises a nose gear wheel, a tail gear wheel, a drive mechanism of the nose gear wheel, and a drive mechanism of the tail gear wheel. The drive mechanism of the nose gear wheel is a hydraulic engine I. The drive mechanism of the tail gear wheel is a hydraulic engine II. The hydraulic system that drives the hydraulic engine I and the hydraulic system that drives the hydraulic engine II contain the same hydraulic elements, and both of them contain a three-position four-way solenoid guide valve, a two-position two-way solenoid guide valve, a two-position three-way solenoid guide valve, a battery and an oil supply valve group.
EFFECT: simple design and long service life are ensured.
