摘  要：
针对4HBL-2型花生联合收获机果土分离及输送中花生果实的漏果、掉果问题,设计了花生联合收获机复收装置。在花生联合收获时,对土壤中遗漏的果实和夹持输送过程中掉落的果实进行复收、清选、集果等作业。并对复收装置进行了设计与试验研究,确定了该装置的最优结构参数和工作参数:复收装置安装角度为20°,复收链输送速度1.2 m/s,复收链杆条间隙10 mm。在机组前进速度为0.6 m/s时,实现收获花生平均净果率为90.16%,平均漏果率为0.12%,提高了花生的收获质量,减少了花生二次复收的劳动强度和作业成本。

摘  要：
In order to solve the existing problems of the leakage and dropping of fruit in the process of peanut harvest using machine, this paper designed the twice-receiving device on 4HBL-2 peanut combine. The device is mainly composed of twice-receiving shovel,conveying device,fixed frame and transmission chain,etc. It can finish the process of twice-receiving,cleaning and gripping fruit when harvesting. Besides,this paper designed and did analysis on twice-receiving device and determined the optimal structural parameters and working parameters: the twice-receiving installation angle was 20°,the twice-receiving chain conveyor speed was 1. 2 m/s,the bar was 10 mm. When the unit speed was0. 6 m/s,the peanuts average net fruit rate was 90. 16%,the average leakage rate was 0. 12%,improving the quality of peanut harvester,reducing the labor intensity of the peanut twice-receiving and operating costs. This equipment will give theory and technical support for the design of twice-receiving multi-function peanut combine. Others,the technical level of peanut combine in China has been greatly improved,and has developed many machines,such as: 4HB-2A,4HBL-2 and 4HL-2,etc. Those machines can complete the work of mining, picking, soil-clearing, fruit-picking, cleaning, and collecting,etc. But the problems of leakage off of peanut fruit in the process of peanut harvesting,there is an average of 5% ~ 8% of the losing. Besides,the cost of twice-receiving of artificial is high and there is no research of twice-receiving on peanut combine in China or at abroad. The main reasons of the existing peanut combine on leakage and off are: first,because of the high maturity of peanuts,the peanut roots and fruit node relay can't meet the requirements of harvesting; second,some peanuts in the process of soil-clearing fell-off on the ground. So the research of this twice-receiving device of peanut combine has important significance.
