    摘要:

    針對原9ST—460型草地振動式間隔松土機在草原試驗中出現(xiàn)的問題,對機具的傳動系統(tǒng),、激振部件以及松土部件進行改進設(shè)計,,并進行了草原試驗。試驗結(jié)果表明,,改進的機具運行平穩(wěn)可靠,、草地作業(yè)效果好,能夠滿足退化草場改良的需要,。作業(yè)后草地的土壤容積密度降低,、含水率增加,作業(yè)后的草地3年內(nèi)平均每公頃年增收155元,。

    Abstract:

    Aimed to the problems revealed in latest grassland tests of the 9ST—460 vibration spacing scarifier, optimizations were carried out on the transmission mode of the parts, vibrating and loosening components. The results of comparing test indicated that the improved device ran steadily and showed good performance. The bulk density of soil decreased but water content increased after scarifying. The yearly average economic benefit increased by 155RMB/hm2 in next 3 years after scarifying, which well fulfilled the requirements of grassland improvement procedure.
