Embodiment 1

[0026] Such as figure 1 and figure 2 As shown, the soil pollution detection device is composed of a detection probe 1, a hollow straight rod-shaped retrieving rod 2, an air pump 3, a motor 4, a connecting pipe 5, a stirring blade 6, a transmission mechanism, and a driven gear 7.

[0027] Specifically, the top and bottom of the retrieving rod 2 are closed and open respectively, and the retrieving rod 2 is provided with a filter plate 8 that can slide up and down, and the side wall of the filter plate 8 is offset against the inner side wall of the retrieving rod 2. , The filter plate 8 divides the cavity of the retrieving rod 2 into an upper cavity 2a and a lower cavity 2b, and the upper cavity 2a and the lower cavity 2b are communicated through the filter holes on the filter plate 8 . Wherein, a screw rod 9 is vertically arranged in the upper cavity 2a, and the lower end of the screw rod 9 is fixedly connected with the filter plate 8, and a threaded hole opposite to the screw...

Embodiment 2

[0033] The structure and principle of this second embodiment are basically the same as that of the first embodiment, except that the transmission mechanism includes a main gear 13 and a drive shaft 14, the drive shaft 14 is vertically arranged in the upper cavity 2a, and the main gear 13 is sleeved and It is fixed outside the lower end of the drive shaft 14, and the main gear 13 and the driven gear 7 are meshed. The upper end of the drive shaft 14 stretches out the material rod 2, and the drive shaft 14 is axially fixedly connected with the material rod 2 through the bearing 12. During actual use, manually rotate the drive shaft 14 to drive the stirring blade 6 to stir the soil.

Abstract

The invention provides a soil pollution detection apparatus, which belongs to the field of soil diagnosis, and solves the problems of poor detection precision of the current soil pollution detection apparatuses. The soil pollution detection apparatus comprises a detection probe and a material-taking rod presenting a hollow straight rod state, the top and the bottom of the material-taking rod respectively present an enclosing state and an opening state, a filter board capable of sliding up and down is arranged in the material-taking rod, an inner chamber of the material-taking rod is divided into an upper chamber and a lower chamber by a filter board, the upper chamber and the lower chamber are communicated through a filter aperture at the filter board, a screw is vertically arranged in theupper chamber, the lower end of the screw is fixedly connected with the filter board, a threaded aperture is arranged at the upper wall of the material-taking rod in a penetrating mode, the upper endof the screw passes through the threaded aperture, the screw is subjected to bolt joint with the threaded aperture, an air pump is fixed at one side of the upper end of the material-taking rod, a gasport of the material-taking rod is communicated with the upper chamber, the through hole is arranged at the sidewall of the upper end of the material-taking rod, the detection probe is arranged in athrough hole in a slidable mode, and a detection end of the detection probe is positioned in the upper chamber. The soil pollution detection apparatus has the advantage of high detection precision.

Description

technical field [0001] The invention belongs to the field of soil diagnosis, and relates to a soil detection device, in particular to a soil pollution detection 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 outer surface is proces...
