The invention discloses a sampling device for detecting pesticide residues in soil. The sampling device comprises a push-pull mechanism for moving the device, a storage mechanism, support mechanisms and an adjusting mechanism; the storage mechanism is mounted below the push-pull mechanism; and the support mechanisms are arranged on two sides of the storage mechanism. The sampling mechanism is adopted; when a drill bit descends and encounters stone, a spring is compressed, a buffer plate drives a sampling pipe and the drill bit to ascend along a second sliding rail, and therefore, the drill bit and the sampling pipe can be protected, and the situation that sampling equipment is damaged is avoided; and a placement equipment is adopted, a fixing plate and a fixing ring cooperate with each other to seal and fix a collecting cylinder, so that a sample in the collecting cylinder can be effectively prevented from spilling and leaking.
本发明公开了一种用于土壤中农药残留检测的取样装置,包括用于移动装置的推拉机构、储物机构、支撑机构、调节机构,所述推拉机构下方安装有所述储物机构,所述储物机构两侧设置有所述支撑机构。本发明通过设置取样机构,钻头下降遇到石头时,弹簧被压缩,缓冲板带动取样管和钻头沿第二滑轨上升,可以对钻头和取样管进行保护,避免了取样设备损坏的情况发生,通过设置放置机构,固定板和固定环共同协作能够对收集筒进行密封固定,能够有效防止收集筒中的样品洒漏。
