试验表明,在脱粒-分离装置中采用振动凹板,在很大程度上可以增加谷物收获量,减少或防止凹板栅格孔被潮湿的碎茎叶和泥土堵塞。这样,可以使联合收割机脱粒装置的谷粒损失大大减少。 Experiments have shown that the use of vibrating concave plates in the threshing-separating apparatus can largely increase the amount of grain harvested and reduce or prevent the block grid holes from being blocked by damp broken stems and soil. In this way, the grain loss of the combine harvester can be greatly reduced.
