现有中耕作物精播机的排种器不适用于小麦,同时,全旋转式双辊排种器在高投种频率下播排小麦时,均匀度下降,甚至造成断条,不能正常作业。本文提出一种新型的静—动式双辊式排种器,可以解决这一问题。经室内试验和初步的田间试验表明,可以满足以5.1公里/小时的速度进行播量为5～11斤/亩小麦精播作业的要求,并可用于稻谷和绿豆单粒点播作业。文中对双辊式排种器工作原理进行了分析,探讨了排种辊上种子的运动规律。
At present, the seed sowing device of the current cultivator precision sowing machine is not suitable for wheat. Meanwhile, when the full-rotating double-roller sowing device sows the wheat under the high planting frequency, the evenness declines and even breaks the bar and can not work normally . This paper presents a new type of static - dynamic two-roll seed metering device that can solve this problem. The indoor experiments and preliminary field experiments showed that the requirement of sowing wheat sowing at a speed of 5.1 km / h for sowing of 5-11 kg / mu of wheat can be met, and it can be used for single-grain sowing of rice and mung bean. In this paper, the working principle of two-roller seed metering device is analyzed, and the movement rule of seeds on the seed-metering roller is discussed.
