最近日本市场上出售了一种旋耕机,它带有日本芝浦会社的耕深自动调节装置,以电子仪器测检耕深,根据电子回路(调节器)的电信号使电磁阀动作,达到耕深自动控制. 这种旋耕机的拖板上方装有深度传感器,可测检拖板角度的变化.由于拖板接地处是耕耘过的地表,因此拖板的角度随地面上下而变化(图1).在拖拉机驾驶座旁安装有控制箱,内有调节器和耕深设定器.在控制箱操纵板上有操纵旋钮(图2),升降旋耕机工作部件或到地头起落机具用最上边的手柄.最下边是调节方式选择旋钮.中间的是耕深设定器旋钮.
Recently, a rotary tillage machine was sold in the Japanese market, with a deep tillage automatic adjustment device of Japan Shibaura Co., Ltd. to test the tillage depth by means of electronic instruments, actuate the solenoid valve according to the electric signal of the electronic circuit (regulator) Deep automatic control .This rotary tiller has a depth sensor installed above the pallet can detect changes in the angle of the carriage .Because the carriage is grounded at the ground surface, so the angle of the carriage changes with the ground up and down (Figure 1) .In the tractor driver’s seat is installed a control box, there are regulators and depth setter in the control box control panel has a manipulation knob (Figure 2), lift the working parts of the rotary cultivator or to the ground landing gear The top of the handle. The bottom is the adjustment mode selection knob. In the middle is the depth setter knob.
