Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0026] As shown in the figure, the soil collection and acid-base measuring device provided in this embodiment includes

[0027] For the soil collection and acid-base measuring device provided in this embodiment, adjust the scale of the soil-taking rod 4 to the soil depth to be collected, use the collar 3 bolts to penetrate the connecting rod 2, fix the soil-taking rod 4 and the connecting rod 2, and tighten Bolt, thereby avoids soil taking lever 4 to rotate relative to c...

Abstract

The invention relates to the technical field of soil detection and particularly to a simple soil collection and alkalinity or acidity testing device. The handle of the simple soil collection and alkalinity or acidity testing device is arranged at the top end of the connecting rod, the connecting rod is hollow; a soil taking rod is inserted into the connecting rod; a sleeved ring is arranged at thebottom end of the connecting rod; a conical sleeve is arranged at the bottom end of the soil taking rod; a fastening bolt is arranged at the sidewall of the sleeved ring; one end of a thin soft pipeis communicated with a phenolphthalein solution reagent while a conical connector is arranged at the other end of the thin soft pipe; and the conical connector is inserted in the conical sleeve. The simple soil collection and alkalinity or acidity testing device has a simple structure, reasonable design and convenient operation, avoids a phenomenon that testing soil drops in the soil collection process and improves the soil collection efficiency efficiently.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a simple soil collection and acid-base measuring device. Background technique [0002] The collection of soil samples is the prerequisite for the evaluation and analysis of soil nutrients and pollution levels in the field of agricultural resource utilization and environmental science, and is one of the important basic tasks for scientific and technological workers engaged in soil research. In the field of agricultural research, soil collectors are often used to collect soil samples. There are two kinds of existing soil collectors, one is composed of a circular base, the middle of the base is connected with a guide seat to drive a sliding device soil-taking rod, and the lower end of the soil-taking rod is connected with a sampling bucket. Generally, the sliding device adopts a screw helical structure. The soil fetcher is mainly used in the field of geological exploration...
