目前,我国农村广泛使用的12马力手扶拖拉机因为牵引力小,所以它的配套犁总耕幅不得不小于拖拉机轮距,形成偏置犁耕地机组,作业时操向性很差。为了解决这一类机组在作业中自动跑偏问题,本文以“ILSP—20型偏置水田单铧犁”(系新产品,通过省级鉴定,已投入批量生产,获科技进步奖)为例,提出平衡其偏转力矩的措施、配置参数及试验结果。
At present, the widely used 12-horsepower tractor in rural areas in China has a small tractive force. Therefore, the total plow size of its supporting plow has to be smaller than that of the tractor to form a biased plow-cultivating unit with poor steering during operation. In order to solve this type of unit in the operation of automatic deviation problems, this paper “ILSP-20 offset paddy field single-plow” (Department of new products, through provincial appraisal, has been put into mass production, won the award of progress of science and technology) as an example , Proposed to balance the deflection torque measures, configuration parameters and test results.
