Soil acid and alkali degree intelligent measuring method based on Internet of things and device thereof

Abstract

The invention discloses a soil acid and alkali degree intelligent measuring device based on Internet of things. The device comprises a body, a feeding control mechanism and a movable fast measuring mechanism, wherein the feeding control mechanism is arranged at the upper side inside the device body; the movable fast measuring mechanism is arranged at the lower side inside the device body; the feeding control mechanism comprises a feeding hopper arranged on the top of the device body and a turntable arranged at the inner wall of one side of the device body; the turntable is positioned at the inclined lower side of the feeding hopper; a moving frame in horizontal arrangement is glidingly arranged at the bottom of the feeding hopper; the bottom of one side, near the turntable, of the moving frame is rotationally connected with a middle rotating rod; a driving connecting rod is glidingly connected onto one side of the turntable; one end of an active connecting rod is rotationally connectedwith one end of the middle rotating rod; two flow control plates in vertical arrangement are rotationally connected under the feeding hopper. The device has the advantages that the design is ingenious; the operation is simple and convenient; the cost is low; the device is applicable to the frequent soil acid and alkali degree measurement in experiments; the manual feeding and discharging are notneeded; the quality and the efficiency of the manual acid and alkali degree measurement are improved. The device is suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of soil measurement, in particular to an intelligent measurement method and device for soil acidity and alkalinity based on the Internet of Things. Background technique [0002] Soil acidity includes two aspects of acidity strength and acidity quantity, or active acidity and potential acidity. Acidity refers to the concentration of H in the soil solution in equilibrium with the soil solid phase, expressed in pH. The amount of acidity refers to the total amount of acid and buffer performance, representing the total amount of exchangeable hydrogen and aluminum contained in the soil. It is generally expressed by the amount of exchangeable acid. Soil pH has a great impact on soil fertility and plant growth. Many soils in Northwest and North my country have high pH values, while red soils in southern China have low pH values. Therefore, crops and plants that are compatible with the pH of the soil can be grown....

AI Technical Summary

Problems solved by technology

Soil pH also has a great impact on the availability of nutrients, such as the availability of phosphorus in neutral soils; the availability of trace elements (manganese, copper, zinc, etc.) in alkaline soils is poor

[0003] At present, the measurement method of soil acidity and alkalinity mainly relies on manual measurement using pH testing equipment, which is limited to a small-scale single pH measurement. There are certain limitations in the experimental research process, and the operation is cumbersome, and it is not convenient for multiple studies. It is not hygienic to use and affects the accuracy of the measurement results. Therefore, we propose an intelligent measurement method and device for the soil pH level based on the Internet of Things to solve the above problems
