我省都江机械厂生产的耕幅为1.1米的旋耕机,同丰收-27拖拉机配套,采用三点悬挂,万向节传动。由于丰收-27拖拉机液压悬挂机构没有位调节,而且液压油泵和动力输出轴是由同一手柄控制离合,要求万向节传动轴倾角不得大于30°。因此,旋耕机组试耕时很困难,提升时怕高了损坏机具,下降时稍不留意就使旋耕机刀轴陷死,造成拖拉机熄火。为了解决旋耕机提升时万向节轴倾角不超过30°的问题,在拖拉机左右提升杆的下端坛接加长杆6(见图),当提升臂处于最高位置
Our province Dujiang Machinery Factory production of 1.1-meter cultivator rotary cultivator, with the harvest -27 tractor supporting, the use of three-point suspension, universal joint drive. As the harvest -27 tractor hydraulic suspension mechanism without bit adjustment, and the hydraulic pump and power output shaft is controlled by the same clutch clutch, universal joint drive shaft tilt angle of not more than 30 °. Therefore, rotary tillage unit is very difficult when trying out the tillage, when raising it, it is afraid to damage the utensil. When it descends a little, the tillage shaft of the rotary tillage machine will be trapped, causing the tractor to stall. In order to solve the problem that the angle of the universal joint shaft does not exceed 30 ° when the rotary tiller is raised, an extension rod 6 (see the figure) is connected to the lower end of the tractor about the lifting rod and when the lifting arm is in the highest position
