Portable detection instrument suitable for soil acidity and alkalinity detection

Abstract

The invention provides a portable detection instrument suitable for soil acidity and alkalinity detection, relates to the technical field of soil detection devices, and solves the problem that a worker is easily stabbed or a detection head is in contact with a hard object to cause abrasion, and automatic cleaning of soil on a detection head cannot be automatically achieved after detection is completed, and organic combination of a scraping structure and a protection structure cannot be achieved through structural improvement. The portable detection instrument suitable for soil acidity and alkalinity detection comprises a detection device body, wherein a first damping block is mounted on the detection device main body. Through cooperative arrangement of the charging plug and the elastic telescopic piece, the head end of the elastic telescopic piece is clamped with the clamping groove, the elastic telescopic piece forms a locking structure of the charging plug, and when the charging plugis pulled out, the elastic telescopic piece covers the upper position of the charging jack of the detection device main body. Therefore, on one hand, the elastic telescopic piece can achieve clampingand locking of the charging plug, and on the other hand, dustproof protection of the charging jack can be achieved.

Description

technical field [0001] The invention belongs to the technical field of soil detection devices, and more specifically relates to a portable detection instrument suitable for soil pH detection. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic substances, water, air, microorganisms, etc., and can grow plants. It is composed of organic matter, soil organisms, water, air, and oxidized humus produced by body decomposition. The pH detector is one of the devices used in soil testing. The pH of the soil has a greater impact on crop growth. [0003] For example, the application number: CN201921404368.9, the utility model discloses a piercing soil detector, which includes a horizontal plate, an insertion rod is inserted into the upper surface of the horizontal plate, and the top of the outer wall of the insertion rod is fixedly sleeved with threads The threaded barrel fits with t...
