采取旋耕和深松两种土壤耕耘部件联合作业,首次应用于水田,不但达到了土壤耕作的农艺要求,同时也解决了农业机械在水田耕作中的困难。如耕深便于控制,拖拉机动力得到了有效的发挥。旋松机的性能完全达到了设计要求。但传动部分较复杂,变速不方便,尚待改进。旋松机在水田作业时,工作幅为1.84米。旱田旋耕时,由于土壤比阻小,工作幅可达到2.1米。土壤坚实度在3.5公斤/厘米~3以下时,旋松机可以正常工作。当坚实度达到4公斤/厘米~3时,东方红-75拖拉机超负荷作业。
It is the first time that paddy field and tillage and soil subsoil components are used in paddy fields to achieve not only the agronomic requirements of soil cultivation but also the difficulties of agricultural machinery in paddy field farming. Such as farming deep easy to control, tractor power has been effectively played. Loosening machine performance fully meet the design requirements. However, the transmission part of the more complex, variable speed inconvenient, yet to be improved. Loosening machine work in the paddy field, the working width of 1.84 meters. Dryland rotary farming, due to the soil resistance than small, working up to 2.1 meters. Soil solidity of 3.5 kg / cm ~ 3 below, the loosening machine can work properly. When the solidity of 4 kg / cm ~ 3, the East Red -75 tractor overload operation.
