    摘要:

    針對4HBL-2型花生聯合收獲機果土分離及輸送中花生果實的漏果、掉果問題,,設計了花生聯合收獲機復收裝置,。在花生聯合收獲時,對土壤中遺漏的果實和夾持輸送過程中掉落的果實進行復收,、清選,、集果等作業(yè),。并對復收裝置進行了設計與試驗研究,,確定了該裝置的最優(yōu)結構參數和工作參數:復收裝置安裝角度為20°,復收鏈輸送速度1.2m/s,,復收鏈桿條間隙10mm,。在機組前進速度為0.6m/s時,實現收獲花生平均凈果率為90.16%,,平均漏果率為0.12%,,提高了花生的收獲質量,減少了花生二次復收的勞動強度和作業(yè)成本,。

    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 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.
