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 was 0.6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.
