辽宁省复州农业机械厂生产的2BQS型气吸双条播种中耕通用机,在播种作业中安装架损坏的比较多,经过观察分析其损坏原因主要是:在地头播种机升起后回转时,镇压轮离地高度不够,造成镇压轮刮地横推,致使安装架受横向力过大,使安装架产生裂纹,当播种机再落地工作时,由于反复受弯曲力作用而折断。 2BQS type gas suction and double sowing general-purpose machine produced by Liaoning Province Fuzhou Agricultural Machinery Factory has more damage to the mounting frame during sowing operation. The main causes of damage after observation and analysis are as follows: when the sowing machine is revolving, Cracking wheel height from the ground is not enough, causing the repression wheel scraping to push, resulting in the mounting frame by the lateral force is too large, so that the mounting frame cracks, when the seeder and then landing work, due to repeated bending force and broken.
