随着水稻收割机械的发展,水田行走机构的研制工作也取得了很大进展(见表1),大部分机具均能在泥脚深度20厘米左右的水田中正常收割。有不少机具已经定型。目前联合收割机上采用的履带行走机构基本有两种型式:即常规的和三角全履带(见图1),但也有的三角履带可 With the development of rice harvesting machinery, great progress has also been made in the development of paddy walking organizations (see Table 1). Most of the implements can be normally harvested in paddy fields with a muddy foot depth of about 20 centimeters. There are many machines have been stereotypes. There are basically two types of track running gear currently used on combine harvesters: conventional and full track (see Figure 1), but some are also available
