由于小四轮驱动拖拉机具有链轨拖拉机和两轮驱动拖拉机所共有的优点,同时又能克服链轨拖拉机结构复杂、重量大和田头转向不合水田农艺要求,以及两轮驱动拖拉机在水田作业时附着性能差的缺点,所以近年来水田用小四轮驱动拖拉机发展很快。 本文根据水田土壤的机械物理性能和水田主要作物的农艺要求,着重在水田拖拉机的牵引性、操纵性、稳定性以及传动系的寿命等方面,根据实地试验和理论分析,详细地阐明小四轮驱动拖拉机对我国南方水田作业是比较适应的。 Because the small four-wheel-drive tractor has the advantages of both the common rail tractor and the two-wheel drive tractor, at the same time, it can overcome the complicated structure and heavy weight of the tractor with the heavy rail and the unwieldy requirements of the farmland and the adhering performance of the two-wheel drive tractor when working in the paddy field Poor shortcomings, so in recent years paddy fields with small four-wheel drive tractor developed rapidly. Based on the mechanical and physical properties of paddy soils and the agronomic requirements of the main crops in paddy fields, this paper focuses on the tractiveness, maneuverability and stability of the tractor in paddy fields and the life of the driveline. According to field tests and theoretical analysis, Tractor driving the paddy field in southern China is more suitable for homework.
