    摘要:

    針對(duì)4HBL-2型花生聯(lián)合收獲機(jī)果土分離及輸送中花生果實(shí)的漏果、掉果問(wèn)題,設(shè)計(jì)了花生聯(lián)合收獲機(jī)復(fù)收裝置。在花生聯(lián)合收獲時(shí),對(duì)土壤中遺漏的果實(shí)和夾持輸送過(guò)程中掉落的果實(shí)進(jìn)行復(fù)收、清選、集果等作業(yè)。并對(duì)復(fù)收裝置進(jìn)行了設(shè)計(jì)與試驗(yàn)研究,確定了該裝置的最優(yōu)結(jié)構(gòu)參數(shù)和工作參數(shù):復(fù)收裝置安裝角度為20°,復(fù)收鏈輸送速度1.2m/s,復(fù)收鏈桿條間隙10mm。在機(jī)組前進(jìn)速度為0.6m/s時(shí),實(shí)現(xiàn)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(zhì)量,減少了花生二次復(fù)收的勞動(dòng)強(qiáng)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.
