Automatic rotary escalator device of harvester
The invention discloses an automatic rotary escalator device of a harvester. The automatic rotary escalator device is composed of a control system, an escalator and an escalator transmission device, wherein the controller controls the whole device to automatically operate; when a vehicle door is opened, a fixed pin is adjusted and a stepping motor gear drives an escalator fixed pin to move upwards to a regulated height; then an escalator rotary direct-current stepping motor drives an escalator rotary speed-reducing gear to open the escalator; then the escalator fixed pin is self-locked and a driver gets off a cab; when the vehicle door is closed, the fixed pin is adjusted and the stepping motor gear drives the escalator fixed pin to transmit and move upwards to the regulated height; then the escalator rotary direct-current stepping motor drives the escalator rotary speed-reducing gear to retract the escalator and the escalator fixed pin is self-locked; and the escalator can be controlled to open and retract by using an escalator unscrewing button and an escalator screwing button, so that the operation of the escalator before and after the driver gets on and off the vehicle is convenient. The automatic rotary escalator device of the harvester is convenient to operate and the time for getting on and off the escalator is shortened; and the working efficiency of the harvester is effectively improved, and danger that the driver falls off from the cab and potential safety hazards of getting on and off the escalator are avoided.
