Portable soil pollution diagnosis equipment

Abstract

The invention provides portable soil pollution diagnosis equipment and belongs to the field of soil diagnosis. The portable soil pollution diagnosis equipment comprises a detection probe and a sampling bucket; a filter plate is horizontally arranged in the sampling bucket, is connected with the sampling bucket through a thread structure and divides an inner cavity of the sampling bucket into an upper cavity and a lower cavity; a hollow rotating shaft is arranged in the upper cavity, the upper end of the rotating shaft extends out of the sampling bucket, the rotating shaft is axially and fixedly connected with the sampling bucket, the lower end face of the rotating shaft is propped against the filter plate, the inner cavity of the rotating shaft is staggered with a filter hole, and an annular stirring blade is sheathed and fixed outside the lower end of the rotating shaft, and a motor capable of driving the rotating shaft to rotate is fixedly arranged on the top wall of the sampling bucket; a holding rod is vertically arranged in the rotating shaft, the upper end of the holding rod extends out of the rotating shaft, and the lower end of the holding rod is fixedly connected with thefilter plate; a through hole is formed in the side wall of the sampling bucket in a penetrating manner in the radial direction of the sampling bucket and is communicated with the upper cavity; the detection probe is rod-shaped, is inserted in the through hole, can slide in the radial direction of the sampling bucket and enables the detection end to be positioned in the upper cavity. The portable soil pollution diagnosis equipment provided by the invention has the advantage of being high in detection accuracy.

Description

technical field [0001] The invention belongs to the field of soil diagnosis, and relates to a soil pollution diagnosis device, in particular to a portable soil pollution diagnosis device. Background technique [0002] The collection of soil samples is the basic stage of the study of soil environmental problems. According to different research needs, sample collection has different requirements. [0003] Existing soil collection and detection equipment, such as a soil pollution detection instrument disclosed in the Chinese Patent Library [Application No.: 201710801430.7; Application Publication No.: CN 107345863A], includes a cylindrical sampling bucket and a top end extending from the sampling bucket. A support shaft and a detection mechanism, the support shaft is threadedly connected to the sampling barrel, the support shaft is provided with a scale line, and the bottom end of the support shaft is fixedly connected with an inverted tapered drill bit, the drill bit The oute...

Problems solved by technology

However, there is still a problem with this instrument: the soil is doped with impurities such as stones, animals and plants, which will not only affect the detection accuracy, but also easily damage the detection probe when it collides with a hard object.
