Background
The existing high-position grain discharging device can not rotate, and the grain discharging position is fixed and unchangeable. Some can rotate, mainly depending on the way that the electric control motor or hydraulic motor pipe drive the horizontal grain discharging pipe to rotate. Generally, the method is divided into a left-handed mode, a right-handed mode, a left-handed mode without limit (potential safety hazard), and a left-handed mode with limit (rotation dead angle).
Some single-direction steering devices have single rotating direction, and when the device needs to return after grain discharging is finished, the required time is long, and the rotating dead angle is large. The main defects of left-right rotation are potential safety hazards, oil pipes of grain discharge pipes are easily caused, and wire harnesses are wound for multiple times to break, so that parts are damaged, people are injured, and other safety accidents are caused. The main defect of limited left and right rotation is that a certain rotating dead angle exists, the angle of the harvester must be adjusted within the dead angle range to put grains, and inconvenience and time waste are caused. In the prior art, the rotation angle of the high-position grain discharge pipe is improved, so that the grain discharge pipe has no dead angle. The high grain discharging pipe which rotates by 360 degrees by an electric control encoder is improved, but the cost of the electric control encoder is higher, and part damage or safety accidents caused by the part damage can be caused due to no limit protection.
