Automatic rotary escalator device of harvester
The invention discloses an automatic rotary escalator device of a harvester. The automatic rotary escalator device of the harvester consists of a control system, an escalator and an escalator transmission device; a controller controls automatic running of the whole device; when a vehicle door is opened, an escalator rotary direct-current stepping motor drives an escalator rotary reduction gear to unfold an escalator after a fixing pin adjusting stepping motor gear drives an escalator fixing pin to move upwards and reach a specified height, an escalator fixing pin is locked, and a driver steps down from a cab; and when the vehicle door is closed, the escalator rotary direct-current stepping motor drives the escalator rotary reduction gear to fold the escalator after the fixing pin adjusting stepping motor gear drives the escalator fixing pin to move upwards and reach a specified height, the escalator fixing pin is locked, unfolding and folding of the escalator can also be controlled by an escalator rotating-out button and an escalator rotating-in button, and operation of the escalator is facilitated before the driver gets on the vehicle and after the driver gets off from the vehicle. The automatic rotary escalator device of the harvester is convenient to operate; the time of the driver who goes up the escalator and goes down from the escalator is shortened; operation efficiency of the harvester is improved effectively; and the driver is prevented against falling from a bride, and potential safety hazards existing when the driver goes up or goes down from the escalator are avoided.
