Description

Caliper for measuring diameter of sunflower disk

Technical Field

The utility model belongs to the technical field of agricultural crop examines kind, specifically is a sunflower disc diameter measurement slide caliper rule.

Background

Sunflower (Helianthus annuus L.) is one of the important oil crops. Sunflower is a capitate inflorescence, growing on the top of the stem, commonly known as the flower disc. The size of the sunflower disc is directly related to the yield, and an index is required to be determined in the sunflower germplasm resource investigation or the genetic improvement of yield-related traits, but no instrument and equipment for simple and rapid determination exists at present, people often use a common tape measure and a caliper for determination, so that the accuracy is insufficient, and the determination for each sunflower disc is performed for 3 to 4 times, so that the time consumption is long.

Therefore, how to provide a caliper for measuring the diameter of the sunflower disc, which can be applied in fields or indoors, directly measure the diameter of the disc from different angles and obtain accurate area of the disc by calculation, is a problem to be solved by the technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sunflower disc diameter measurement slide caliper rule through pricking sunflower disc center at chi frame center, can directly survey the flower disc diameter from different angles, utilizes to calculate and obtains accurate flower disc area, provides the scientific foundation for sunflower germplasm innovation.

For reaching the above-mentioned purpose, the utility model provides a sunflower disc diameter measurement slide caliper rule, including slide caliper rule base, fixed branch, main scale, slip vernier and fixed awl, the main scale both ends are fixed on the slide caliper rule base, the main scale is provided with the vernier spout, the setting of slip vernier is in the vernier spout, slip vernier and main scale sliding connection, the below of slide caliper rule base is provided with fixed branch, the fixed branch both ends are fixed on the slide caliper rule base, fixed branch's center is provided with fixed awl, fixed awl runs through the center of main scale.

Furthermore, the main scale sets up the fixed cone position as the benchmark, the scale of main scale uses the fixed cone to set up as symmetry point symmetry, the scale of fixed cone position is 0, and the main scale is kept away from the fixed cone scale and is increased in proper order.

Furthermore, the measuring range of the main scale is 0-600mm, and the precision of the main scale is 1 mm.

The utility model discloses simple structure, fixed awl, the main scale jointly uses sunflower quick flower disc diameter that can standardize fast with the slip vernier, through prick sunflower flower disc on the fixed awl at the main scale center, rotate the sunflower can follow different angle survey flower disc diameters, reduce the error that the people was caused, do benefit to the accuracy, the size of rapid survey sunflower flower disc diameter, the standardization of sunflower flower disc diameter measurement has been improved, measurement of efficiency and experimental accuracy have been improved, and the cost is low, and the carrying convenience is used, more is favorable to field work's advantage.
