一种硬质土壤取土器
本技术涉及一种土壤取样工具,特别是一种硬质土壤取土器。
技术介绍
在对土壤进行室内测试研究时,需要使用土壤取样工具采集土样,之后再对采集的土样进行分析、检测。目前常见的土壤取样工具主要是手持脚踏式取土器,其结构是在杆体前端设置取土筒,使用时手握杆体(或杆体上的手柄),脚踩脚踏向下用力将取土筒插入土中进行取样。该取土工具存在下述缺点,当遇到硬质土壤时,通过用力踩脚踏将取土筒插入土中相当费力,造成取样困难。
技术实现思路
本技术的目的在于,提供一种硬质土壤取土器。本技术具有取土方便,收纳容易和适用性强的特点。本技术的技术方案:一种硬质土壤取土器,包括杆体,杆体头端与取土筒连接,杆体末端与捶打组件螺纹连接;所述的取土筒的开口端设有取土刃,取土筒的侧壁上设有从取土刃起沿取土筒轴向延伸的取土口;所述的杆体头端还设有退土组件;所述的退土组件包括滑动柱,滑动柱与设于杆体头端的中空内筒活动连接,滑动柱端部与推杆连接,推杆端部活动穿过取土筒封闭端与设置于取土筒内的推块连接;所述的退土组件还包括推环,推环内壁与杆体滑动连接,推环内壁上设有连接部件,连接部件穿过设于杆体侧壁的滑动槽与滑动柱连接;所述的捶打组件包括捶打套,捶打套开放端套于杆体末端并与杆体末端螺纹连接,捶打套底部还设有支撑柱,支撑柱插入设于杆体末端端面的支撑孔中;所述的支撑柱长度大于支撑孔深度。前述的硬质土壤取土器中,所述的滑动柱与取土筒封闭端间的推杆上还设有复位弹簧。前述的硬质土壤取土器中,所述捶打套上还设有手柄。前述的硬质土壤取土器中,所述的杆体末端在拆除捶打组件后还能与延长杆体螺纹连接。前述的硬质 ...
