Embodiment 1

[0028] A portable soil crust flexural strength measuring instrument, which includes a funnel-shaped fluid storage tank 1, a through hole 2 is provided at the bottom of the fluid storage tank 1, and a support leg 3 is fixed on the outside of the fluid storage tank 1. There are also two parallel guide rails 4 outside the bottom of the groove 1. The length of the guide rail 4 is shorter than the length of the supporting leg 3 to avoid contact between the guide rail 4 and the soil during measurement, which will affect the measurement result; The inner sides of 4 are respectively provided with sliding grooves 5, and a measuring plate 6 is arranged between the two guide rails 4. The two ends of the measuring plate 6 are respectively placed in the sliding grooves 5, and the measuring plate 6 can slide up and down along the sliding groove 5; A receiving groove 7 is fixed on the top of the plate 6, and a fluid pipe 8 is fixed on the fluid storage tank 1 directly above the receiving groov...

Abstract

The invention discloses a portable instrument for measuring the bending strength of a soil crust. The instrument comprises a fluid storage tank, wherein a through hole is formed in the tank bottom of the fluid storage tank; supporting legs are fixedly arranged on the outer part of the fluid storage tank; two mutually parallel guide rails are further arranged on the outer part of the tank bottom of the fluid storage tank; a measuring plate capable of sliding up and down along the guide rails is arranged between the guide rails; a receiving tank is fixedly arranged on the top of the measuring plate. The portable instrument for measuring the bending strength of the soil crust is simple in structure and ingenious in design; when the portable instrument is used for measuring the bending strength of the soil crust by taking lines as measuring objects, measurement is accurate and reliable; the portable instrument for measuring the bending strength of the soil crust solves the problems that when the conventional measuring device measures certain points on the soil crust, the crust strength sharp difference between the points is sharp and a large number of points are required to be distributed, so that the workload is reduced and the working efficiency is improved. The novel measuring device, provided by the invention, provides quantitative indexes and an important guidance for preventing wind and fixing soil by using the soil crust.

Description

[0001] Technical field: [0002] The invention relates to a measuring instrument, in particular to a portable soil crust flexural strength measuring instrument. [0003] Background technique: [0004] According to the survey, the current soil erosion area in my country is 3.5692 million square kilometers, of which the wind erosion area is 1,957,700 square kilometers. Wind-proof and soil-fixing of soil crust is one of the important measures to prevent wind erosion. Soil crust is a denser soil surface crust formed by the combined action of rainfall, runoff, or organisms on the surface soil. It has a certain hardness and strength, and is generally a few millimeters thick. Soil crusts can resist strong winds carrying soil particles, especially fine particles, into the airflow, reducing local soil wind erosion and the formation of sandstorms. [0005] At present, in the research of soil crust, the strength of soil crust is an important technical index to characterize its anti-corrosion ef...
