气吸式播种机是靠风机产生真空采工作的,风机靠动力输出轴传递动力。有些拖拉机动力输出轴是非独立式的,当拖拉机停车或换档时,主离合器一分离,动力输出轴也随着停止转动,致使风机停转而造成漏播。为了解决漏播问题,驾驶员常采用双操向杆起步,即挂档后先同时将两操向杆拉到底,后结合主离合器,等风机达到工作转速后再结合转向离合器。这种操作方法劳动强度大,而且容易跑偏,对拖拉机也不利。因此,应寻求用一种改装方案来避免产生
Air suction seeder is built by the fan to produce vacuum mining work, the fan power output shaft transmission power. Some tractor PTO shafts are non-stand-alone. When the tractor is parked or shifted, the main clutch is disengaged and the PTO shaft stops rotating as well, causing the fan to stall causing leaks. In order to solve the leakage problem, the driver usually adopts double steering rod to start, that is, after the gear is engaged, the two steering rods are pulled to the bottom at the same time, and then combined with the main clutch, and then combined with the steering clutch after the fan reaches the working speed. This method of operation labor-intensive, but also easy to deviation, the tractor is also unfavorable. Therefore, should seek to use a modified program to avoid the production
