4ZBL-2背负式籽瓜联合收获机的设计

Design of 4ZBL-2 Knapsack Combined Harvesters for Seed Watermelon

半机械化收获籽瓜需耗费大量的劳动力,整个生产过程劳动强度大,劳动效率低,收获成本高。为解决这个问题设计了4ZBL-2背负式籽瓜联合收获机,并对样机的工作性能进行了试验验证,结果表明该机可满足设计要求,可在籽瓜自然状态下一次完成籽瓜的集条、捡拾、脱粒及装袋等作业。该项技术填补了国内籽瓜联合收获的空白,并受到当地农户好评。

The semi-mechanized harvesting of seed watermelons is labor-consuming,the whole process is high in labor intensity and harvesting costs but low in efficiency.In order to solve these problems,a 4ZBL-2 knapsack combined harvester was designed for seed watermelons,the working performance of the prototype was experimentally verified,concluding that the machine can achieve the operations of collection,pick-up,threshing and bagging at one time.The machine fills the gap of combined watermelon harvesting in China and is very popular among farmers.
