目前,旋耕机械在我国已被广泛使用,正逐步发展成为农业机械的一个重要门类。我国目前的驱动型耕作机械产品有旋耕机及复式作业机、驱动式圆盘犁、耕耙犁、水田驱动耙、立式转齿耙等,但产量比较大的主要为旋耕机。目前,国内大中拖配套旋耕机保有量约15万台,手拖和小四轮配套旋耕机200万台。旋耕机在南方水稻生产机械化应用中已占80%比例,北方的水稻生产、蔬菜种植和旱地灭茬整地也广泛采用了旋耕机械。1旋耕机的特点
At present, rotary tillage machines have been widely used in our country and are gradually developing into an important category of agricultural machinery. At present, China’s driving-type tillage machinery products include rotary tillage machines and double-working machines, driven disc plows, tillage harrow plows, paddy-driven harrows and vertical tine harrows. However, the major ones are rotary tillers. At present, the domestic large and medium-sized drag rotors hold about 150000 units, hand trailers and small four-wheel rotator 2 million units. Rotary cultivators have accounted for 80% of the mechanized application of rice production in the South. Rotary implements are also widely used in rice production, vegetable cultivation and dry-land stubble preparation in northern China. 1 Rotary machine features
