Falling hopper for Grain Bulk Density Meter

Abstract

The invention discloses a blanking hopper for a grain bulk density measuring instrument. The bottom of the bottom is flush with the discharge port of the inner cylinder. The first blanking cylinder includes the first cylinder body. The material channel in the first cylinder is an inverted trapezoid. The blanking hopper is placed on the bulk density tester. The moving handle moves along the bar-shaped groove, driving the baffle to rotate until the baffle block matches the limit block, the discharge port of the inner cylinder is closed, put the crops in the inner cylinder, press the button, the baffle block and the limit block The positioning block is disengaged, and under the action of the spring, the discharge port of the inner cylinder is opened, and the crops will fall into the bulk density cylinder, and then proceed according to the operation steps of measuring the bulk density, because the uniformity and uniformity of the crops falling are good , the accuracy of the measured bulk density is high, the bulk density index is accurate, and the repeatability of the results is good.

Description

technical field [0001] The invention relates to a grain bulk density measuring instrument, in particular to a dropping hopper for a grain bulk density measuring instrument, which belongs to the technical field of analytical instruments. Background technique [0002] Bulk density is the mass of grain grains per unit volume, expressed in grams per liter (g / L). Grain bulk density is a comprehensive index that reflects the quality of grain size, shape, uniformity, uniformity, quality, depth of ventral groove, and endosperm texture. In the grain quality standards of many developed countries in the world, the test weight is listed as an important indicator. my country's grain sector also regards test weight as an important parameter for evaluating grain quality. At present, when measuring the bulk density of grain, the grain to be tested is usually dumped directly into the bulk density tester with a blanking device. Since the scattering of grain particles is different each time,...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is to provide a kind of blanking hopper for the grain bulk density measuring instrument for the above defects, which overcomes the poor accuracy of the bulk density and the inaccurate bulk density index caused by the blanking device of the existing grain bulk density measuring instrument. The defect of poor repeatability, after adopting the falling hopper of the present invention, the regularity and uniformity of the grain particles in the bulk density measuring instrument are good, the accuracy of the measured bulk density is high, the bulk density index is accurate, and the repeatability of the results is good.
