Abstract

The invention discloses a foot-stepping-type sampling device for soil pesticide residue detection and belongs to the field of soil pesticide residue detection. The problem that an existing soil sampler is unsuitable for soil pesticide residue detection sampling is solved. According to the foot-stepping-type sampling device, a first T-shaped rod comprises a first long rod and a first short rod, andthe lower end of the first long rod is fixedly arranged on the first short rod. A second T-shaped rod comprises a second long rod and a second short rod, and the lower end of the second long rod is fixedly arranged on the second short rod. A first hand-holding part and a second hand-holding part are arranged at the two ends of a hand-holding rod correspondingly, and a long rod connecting part isarranged at the middle of the hand-holding rod. The upper end of the first long rod and the upper end of the second long rod are fixedly connected with the two ends of the long rod connecting part correspondingly, and the first T-shaped rod and the second T-shaped rod are oppositely and parallelly arranged through the long rod connecting part. Under the external force effect, a foot stepping platecan slide up and down between the first long rod and the second long rod. The upper end of a connecting rod is vertically and fixedly arranged on the bottom face of the foot stepping plate, the lowerend of the connecting rod and the upper end of a sampling cylinder are in threaded connection, and the lower end of the sampling cylinder is in a sawtooth shape.

Description

technical field [0001] The invention relates to a soil pesticide residue detection and sampling device, which belongs to the field of soil pesticide residue detection. Background technique [0002] At present, before testing soil pesticide residues, inspectors mainly collect soil samples through soil samplers. Existing soil samplers can be divided into manual soil samplers and electric soil samplers. When a manual soil sampler is used for soil sample collection, inspectors need to knock the sampling head into the soil layer at a predetermined depth with a sampling hammer. The electric soil sampler rotates the sampling head through a motor, and then drills into the soil layer at a predetermined depth. Due to the characteristics of pesticide residues in the soil, the sampling samples for the detection of pesticide residues in the existing soil are the soil in the shallow soil layer (0-20 cm). However, the existing manual soil samplers and electric soil samplers are designed...
