4HBL-4型二垄四行半喂入自走式花生联合收获机

论述了4HBL-4型二垄四行半喂入自走式花生联合收获机结构和工作原理,该机一次对二垄四行花生完成挖掘、去土、输送、摘果、分离、清选和集箱等作业。悬浮式仿形机构,使机器具有更好的地面仿形效果;花生收获双层集果清选装置,实现了对花生果进行两次清选。经山东省农业机械试验鉴定站田间检测：摘果率为98.9%,总损失率为3.3%,破损率为0.2%,含杂率为3.1%,纯作业生产率为0.16 hm2/h,达到了设计和相关标准要求。

Type-4HBL-4 Two-ridges and Four-lines Semi-feeding Self-propelled Peanut Combine Harvester

The structure and working principle of two-ridges and four-lines semi-feeding self-propelled peanut type-4HBL-4 combine harvester was introduced. It could completely harvest two-ridges and four-lines peanuts in one time and accomplish digging, excavation to soil, transportation, picking, separation, cleaning, collection boxes and other operations. The suspension type with square institution which had better ground-profiling effect was adopted. Collecting-fruit equipment was used to clean twice. Throughout the test in the field, it met the requirements of design and relevant standards with the picking rate of 98.9%, the total loss rate of 3.3%, breakage rate of 0.2%, impurity rate of 3.1%, and net operating-hour productive efficiency of 0.16 hm2/h, which met the design requirements and related standards.
