本文介绍了最新研制的新型直压式手动原状土取土钻的设计及应用。该钻由钻头、钻筒、连接座、钻杆组成。钻头非开口，相对于钻筒内外壁的“双凸”构造及在钻筒上裁一与钻头刃口直径相当的平行于轴的口。组合钻杆，继承深度标划。着重分析了该铭的结构性能。二年多的试用试验表明，该钻仅凭一人手动操作可轻松获取整个剖面继承深度原状土样和水稻土剖面原状土样、所获土样可满足野外剖面观察及室内物理、化学分析的需要，并相应提高工时工效５０余倍．该钻的广泛应用将打破土壤调查制图受大工作量、长周期、高费用支出及作物生长季节的限制，给土壤调查带来一场革命，同时也利于新土壤分类系统的快速实施及推广。
This article introduces the design and application of the newly developed straight-type manual soil-boring machine. The drill by the drill, drill pipe, connecting seat, drill pipe composition. The drill is non-open, with a “double-convex” structure relative to the inner and outer walls of the barrel and a hole parallel to the shaft cut to the diameter of the drill edge. Combination drill pipe, inheritance depth planning. Emphasis analysis of the structure of the Ming performance. More than two years of trial tests show that the drill can easily obtain the intact intact soil samples and the undisturbed soil samples of paddy soil profiles by one manual operation. The obtained soil samples can meet the needs of field profile observation and indoor physical and chemical analysis , And a corresponding increase in working hours more than 50 times. The wide application of the drill will break the limitation of the soil survey drawing by the large workload, long cycle, high expense and crop growth season, bring a revolution to the soil survey and be beneficial to the rapid implementation and popularization of the new soil classification system.
