Abstract

Provided are a device and method for cutting straw.A travel switch is arranged on the left side of a notch of an accommodating groove, and a pair of active infrared intrusion detector switches is arranged on the two sides of the position of the notch of an accommodating groove.After a cutter is lowered to the notch of the accommodating groove, the speed is lowered, so that the risk of damaging operators' hands by the cutter is lowered.The rising speed of the cutter is quicker than the descending speed, and the operation time is saved.A pair of second active infrared intrusion detector switches is arranged at an endpoint of a short shaft of a cam and a knife rest.Only when the cutter rises to the highest position can the motor stop rotating, so that it is guaranteed that the cutter returns.
