目前,常用的取土钻全部为铁制,重7.5斤,长1.4米,价值百元左右,携带和使用不便,特别是水田取土非常费力.为此,我们设计了一种结构简单、携带轻便的简易取土钻.这种取土钻,分为铁质钻头和木质“T”字形杆柄两部分.其大小、长短以及粗细可根据使用对象,采土点与采土量而定.采土点少而采土量大,钻头铁管可粗些,反之则细些;旱地“T”字形柄可短些,水田地则可长些.钻头为一般铁管或钢管.其钻头铁管长27厘米,直径3厘米,容土部分长20厘米(为一般耕作层土壤厚
At present, all commonly used earth-boring drills are made of iron with a weight of 7.5 kg and a length of 1.4 m, worth about RMB100, which is inconvenient to carry and use, and especially the paddy soil is very laborious. Therefore, we designed a simple structure Easy earth boring machine This earth boring drill is divided into two parts: iron drill bit and wood T-shaped shaft.Its size, length and thickness can be determined according to the object of use, soil pick-up point and the amount of earth mined. Less soil pick-up area and large amount of earth, drill pipe can be more coarse, and vice versa; dry “T” shaped handle can be shorter, paddy fields can be longer. Drill for the general iron pipe or steel pipe. Tube length 27 cm, diameter 3 cm, part of the soil is 20 cm long (for the general farming layer soil thickness
