Abstract: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 twicereceiving device on 4HBL-2 peanut combine. The device is mainly composed of twicereceiving shovel, conveying device, fixed frame and transmission chain, etc. It can finish the process of twicereceiving, cleaning and gripping fruit when harvesting. Besides, this paper designed and did analysis on twicereceiving device and determined the optimal structural parameters and working parameters: the twicereceiving installation angle was 20°, the twicereceiving chain conveyor speed was 12m/s, the bar was 10mm. When the unit speed was 0.6m/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 twicereceiving and operating costs. This equipment will give theory and technical support for the design of twicereceiving multifunction 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, soilclearing, fruitpicking, 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 twicereceiving of artificial is high and there is no research of twicereceiving 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 cant meet the requirements of harvesting; second, some peanuts in the process of soilclearing felloff on the ground. So the research of this twicereceiving device of peanut combine has important significance.
