Device for control cutting portion of full feed type combine

摘要

The present invention proposes a preload control device for controlling so that soil is not introduced during harvest. According to the present invention, there is provided a driving apparatus for a vehicle, comprising: a main frame for supporting a driving source; a running portion provided on a bottom surface of the main frame; a horizontal sensor for measuring a tilt in the left-A main body horizontal control device composed of a plurality of hydraulic cylinders for adjusting the level of the main body frame, a normal type combine having a height adjustable through a preliminary lifting device at the front of the main frame, It is a mounting control device. The preloading control device of the present invention is provided with a preload detecting means installed on the bottom surface of the preloading portion and capable of detecting the inclination in the left and right direction and the inclination of the forward ascending direction of the preloading portion itself; And a control unit for controlling the horizontal adjustment of the body frame and the height adjustment of the preloading unit based on the sensing value of the sensing unit. Here, the control unit controls the body horizontal control apparatus so that the body frame also has the same inclination with respect to the right and left inclination of the preliminary mounting unit, and controls the cutting unit such that the prevailing frame inclination of the preliminary mounting unit is raised.
