一、概述 目前生产的机耕船是水田机械化的一支生力军,但存在着机组纵向稳定性较差,直线行驶性能不好等缺点。只配一种驱动轮,且入土深度不能调节,缩小了机耕船的适应范围。虽作了适当的改进,但改进后的结构却较复杂,重量增大,制造成本较高。 I. Overview The current production of tillage boat is paddy field mechanization of a new force, but there is the unit longitudinal stability is poor, poor linear driving performance and other shortcomings. Only with a drive wheel, and the depth can not be adjusted into the soil, reducing the scope of the machine to adapt to farming. Although made appropriate improvements, but the improved structure is more complex, heavier, higher manufacturing costs.
