针对单体打捆机捡拾联合收获后田间滞留的水稻"站秆"及"残茬"收净率较低,以及圆捆打捆机绕线卸捆时需停机导致作业效率低等问题,该文将现有水稻联合收获机的脱粒清选和粮箱等装置与圆捆打捆装置置换,在输送槽出口与打捆装置集料口处设置集料装置作为缓存区,采用自动控制技术控制各功能部件连续作业,最终研发出集切割、捡拾、收集、打捆、集捆等功能于一体的田间水稻秸秆收集与连续打捆复式作业机。田间性能试验表明:在作业档的工况条件下,作业速度越快,成捆效率越高,但圆柱规范度程度越差;经测定,整机以中速档(1.1 m/s)连续作业3.4 h后,其成捆率为98%,生产率为0.4 hm^2/h,秸秆收净率为95%。该研...

A large number of rice "standing-stalk" and "stubble" will remain in the paddy field after the rice is harvested by a combined harvester. At present, the harvest rate of rice "standing-stalk" and "stubble" remained in the paddy field after joint harvest using single baling machine is low. The single baling machine is usually pulled by a tractor which causes intermittent collection and baling of stubble in paddy field. The working efficiency of traditional baling machine is low due to the halt of the baling machine when unloading the baling wire...
