1GH-3型行间耕整机设计与试验

Design and Experiment of 1GH-3 Inter-row Tillage Machine

通过刀片在刀辊上的合理排列及拆装,使行间耕整机实现行间浅旋、垄台碎茬及全幅旋耕3种作业,试验表明机具3种状态作业质量均满足农艺要求。通过行间浅旋作业时拖拉机行走轮对土壤压实试验测定结果表明:压实对0～10 cm土层土壤容积密度影响显著,在机组前进速度为0.50、0.65和0.92 m/s情况下,压实比未压实土壤容积密度分别增加8.5%、7.0%和6.2%,而对10～20 cm土层土壤容积密度影响不显著;压实使刀片切土时扭矩也有所增加,但扭矩增加不显著。

An inter-row tillage machine was developed with standing stubble. Tillage operations were performed in the ridges and furrows alternately which can be used for inter-row shallow-tillage, ridge stubble- breaking or full-width tillage operation through the rational arrangement of blades on the rotor and disassembling in the blades, or one machine for three purposes. The experiments showed that this machine met all the agrotechnical requirements in the three operational states. The determination results of soil compaction caused by the tractor tyres in the inter-row shallow-tillage operation showed that soil compaction had a significant effect on the soil bulk density at the depth of 0 - 10 cm. The soil bulk density increased by 8.5%, 7.0% and 6.2% when the machine traveled at speeds of 0.50 m/s, 0.65 m/s and 0.92 m/s, respectively. Soil compaction had little effect on the soil bulk density at the depth of 10 - 20 cm. Soil compaction also caused an increase in the torque of the blade when cutting the soil, but the increase in torque was not significant.
