    摘要:

    針對傳統(tǒng)花生聯(lián)合收獲機剛性夾持鏈夾持損失率偏高的問題，提出了三夾持帶柔性夾持技術(shù)，并設(shè)計了三夾持帶夾持輸送裝置。通過試驗臺試驗確定了帶型、帶距、帶速等參數(shù)，并通過與剛性夾持鏈的田間對比試驗，對拉斷落果率、夾持喂入率、夾斷率、去土率、掉株率、掉果率等試驗指標(biāo)進行了綜合評價。試驗結(jié)果表明，三夾持帶柔性夾持輸送方式損失率較低。

    Abstract:

    In traditional peanut combine harvest, loss rate of peanut in the process of chain rigidity clamping is rather high. Thus, three-belt clamping technology was proposed. Making use of general three-belt flexible clamping cushion to peanut, general three-belt clamping feeding device was developed. Belt type, belt distance, belt speed and so on were determined through bench tests. And according to the field comparative tests to chain rigidity clamping feeding mode, comprehensive evaluation was done on testing index, such as pulling-down peanut drop rate, clamping feeding rate, clamping breaking rate, soil removing rate, straw falling rate, peanut falling rate and so on. The results showed that loss rate of the general three-belt clamping feeding mode was rather low and more suitable for current Chinese peanut harvest situation.
