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.
Description
technical field [0001] The invention relates to an agricultural machinery automation device, in particular to an automatic revolving escalator device for a harvester. Background technique [0002] China is a traditional large agricultural country. With the development and progress of agricultural mechanization, the degree of agricultural integration is getting higher and higher. Harvesters are more and more used in agricultural operations. Harvesters are complex in structure and bulky. In order to better drive in the open The field of view of the operator, the cab is set at a higher position, in order to facilitate the driver to go up and down the cab, the harvester needs to be equipped with an up and down escalator, because the width of the harvester is limited, so the escalator cannot be fixed on the outside of the harvester, the existing The technology is to design the escalator as a rotating type, and there is a locking mechanism. When the driver wants to get on the harv...
