我国现有的11Kw轮式拖拉机是旱地犁耕的巨大农用动力资源。从旱作农业对实施机械化深耕的要求看,其深耕的主要限制因素是该拖拉机深耕附着性能恶化所致。分析性能恶化的主要原因是机体横向倾斜和配套犁的耕作阻力的综合作用结果。从深耕、土壤比阻与拖拉机附着性能的关系分析,改善该拖拉机的深耕附着性能,保持25cm耕深,提高耕地生产率,降低油耗等,是可以实现的。近期可以采用附着配重以改善附着性能。今后应通过研究新型的适应旱地深耕的行走装置,以从根本上改善该种拖拉机深耕附着性能。
The existing 11Kw wheeled tractor in our country is a huge agricultural power resource for dryland plowing. From the requirements of dry farming for implementing mechanized deep plowing, the main limiting factor of deep plowing is the deterioration of deep plowing and adhesion of the tractor. Analysis of the main reasons for the deterioration of the performance of the body is tilted and supporting plowing plowing the combined effect of the results. From deep plowing, soil specific resistance and tractor attachment performance analysis, to improve the tractor plowing attachment performance, maintain 25cm plow depth, increase productivity and reduce fuel consumption, etc., is to be achieved. Recently, attachment weights can be used to improve adhesion. In the future, we should fundamentally improve the deep-tillage attachment performance of this tractor by studying a new type of walking device that adapts to deep plowing in drylands.
