Abstract

The invention relates to a field trial tilling depth and profile measurement instrument and a measurement method thereof. The problems of complicated structure and poor accuracy of conventional measurement instruments are solved. The field trial tilling depth and profile measurement instrument comprises a frame; the four corners of the frame are provided with lifting mechanisms; the frame is formed from two transverse supports and two longitudinal supports; the transverse support on at least one side is provided with a plate groove vertically; a scale plate is inserted in the plate groove vertically; the front side wall surface of the plate groove is provided with a plurality of arc-shaped probe grooves uniformly in the vertical direction; probes are vertically inserted in the arc-shaped probe grooves. The measurement instrument has the advantages of simple structure, high measurement accuracy, easy operation, damage resistance and multiple detection function.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a field test depth and profile measuring instrument and a measuring method thereof. Background technique [0002] Working depth and flatness are important indicators for evaluating the performance of agricultural machinery, and an important basis for judging the quality of land plowing and agronomic requirements for crop sowing; the terrain profile after plowing the land is an important reference standard for evaluating and optimizing agricultural machinery. [0003] The traditional operation depth measurement methods include the inserting ruler method and the insertion rod method, etc., and the measurement accuracy is low; there are also real-time monitoring devices for the operation depth installed on the operation tools, such as the patent "a micro-tiller plow depth detection device" whose publication number is CN202587799U , but this is to solve the problem of unstable pl...
