Measure ruler special for animal shape size measurement

Abstract

The invention discloses a measure ruler special for animal shape size measurement. The measure ruler comprises a graduation ruler and an elastic device used for enabling the graduation ruler to be contracted backwards, the elastic device is mounted on a shell, a ruler head is arranged at one end of the graduation ruler, a connecting segment for connecting the elastic device is arranged at the other end of the graduation ruler, a laser transmitter is arranged on the surface, above the graduation ruler, inside the shell, a laser receiver is arranged at the position, below the graduation ruler, of the shell, a touch button is arranged on the shell, a displayer is arranged on the outer surface of the shell, a sensor used for monitoring the moving direction of the graduation ruler is arranged inside the shell, and the laser transmitter, the laser receiver, the touch button and the sensor are connected to a controller. The size of the graduation ruler can be efficiently and precisely determined in a laser counting mode, and meanwhile the ruler needs to solve the problem that in the data measuring process, due to the measurement requirement, sometimes, the graduation ruler is contracted inwards, and the backward counting of the graduation ruler is required.

Description

technical field [0001] The invention relates to a size measuring tool, in particular to a measuring ruler specially used for measuring the shape and size of animals. Background technique [0002] When measuring the body size (chest girth, abdominal girth, body length, body oblique length, pipe girth, etc.) of animals (cattle, sheep, pigs and other large livestock and poultry), the general soft ruler and tape measure (for measuring clothes) are often used. , construction sites) for measurement. When measuring with a soft ruler, the surveyor needs to read the measurement data with the naked eye. Manually read numbers are subject to human influence (reading errors by the naked eye, environmental interference, etc.). However, animals have a certain wildness, and often cannot stand quietly when measuring. When measuring with a general soft ruler, the measured size data is inaccurate due to the twisting of the torso of the animal. Moreover, large livestock animals such as cows...

Problems solved by technology

The inaccurate measurement data will lead to the fact that the statistical data in the livestock animal breeding work cannot truly reflect the actual production situation, making it difficult for the breeding work to achieve the originally formulated breeding goals
