Portable multipurpose livestock body circumference measuring tool

Abstract

A portable multipurpose livestock body circumference measuring tool belongs to the measurement tool technology field, and is characterized in that the left end of a main rod I is fixedly connected with the right end of a supporting plate, a pin shaft hole I of a main rod II is connected with a pin shaft hole II of a connecting plate movably, and a master sliding block is connected with the inner wall of the main rod II slidably; a slave sliding block is connected with the two top chutes of the two main rods slidably, the left end of a measuring rope I is fixedly connected with the center of a wire wheel via a through hole of the master sliding block, and the right end of a measuring rope II is fixedly connected with the top end of a semi-circular measurement head II in a lasso via a connecting head I and a semi-circular measurement head I; the left end of the connecting head I is fixedly connected with the right end of the main rod II via a screw, and the left end of a connecting head II is fixedly connected with the right end of a main rod V via a screw; an instrument box is fixedly connected with the left part of the main rod I, a range finder is placed in the instrument box, the orientation of the measuring head of the range finder is consistent with the direction of the end not having a baffle of the instrument box, and the included angle of the measuring head and a baffle in a sliding baffle right ahead the measuring head is 90 degrees. The portable multipurpose livestock body circumference measuring tool of the present invention adopts the wireless range finding for the first time, is high in measurement safety and low in labor intensity, is rapid and accurate, and is convenient to carry.

Description

Technical field [0001] The invention belongs to the technical field of measuring tools, and specifically relates to a measuring tool for the body circumference of livestock. Background technique [0002] With social progress and the continuous improvement of people’s living standards, the demand for large-scale livestock (cattle, horses, deer, etc.) products is increasing, which creates a vast market space for the livestock breeding industry, but also brings severe challenges. Only by achieving leapfrog improvement in quantity and quality, can we meet the growing needs of people and be in a favorable position in the fierce market competition. [0003] Improved breeds are the foundation of industrial development, population selection is a fundamental measure to improve population genetic level and production performance, and performance measurement is a prerequisite for improving population selection and breeding. The performance measurement is a complete performance recording syst...

Problems solved by technology

At this stage, the general tool for measuring livestock pipe circumference, chest circumference, abdominal circumference and testicular circumference is a soft ruler, which has poor safety and incidents of wounding people often occur. In addition, due to concerns about safety issues, the measurer cannot carefully observe the measurement data, which makes the measurement time becomes longer, the measurement error becomes larger
