Intermittent negative-pressure taking type grain moisture detection equipment

Abstract

The invention relates to intermittent negative-pressure taking type grain moisture detection equipment and belongs to the technical field of seed moisture detection. The intermittent negative-pressure taking type grain moisture detection equipment comprises a shell, wherein a material inlet is formed above the shell; a plurality of aggregate bins are arranged on the shell in an alternate way; an air blower is arranged below the material inlet on the side surface of the shell; a moisture detector is arranged on a position close to the lower side of the air blower on the outer side of the shell; the moisture detector comprises a sampling channel, a sampling bin, a rolling wheel pair and a rolled material collection bin in turn according to the advancing direction of the sampled material. According to the technical scheme, through the fit design of the sampling channel and the sampling bin, an aim of independent sampling can be achieved; moreover, in combination with a seed separation function, the sampling of full particles can be ensured; the whole equipment combines the drying, separation and moisture detection of seeds, realizes integrated design and comprehensive functions and has good practicability.

Description

Technical field [0001] The invention relates to a grain moisture detection device, in particular to an intermittent negative pressure reclaiming type grain moisture detection device, which belongs to the technical field of seed moisture detection. Background technique [0002] Grains are easily heated and deteriorated during storage, such as excessive moisture and poor ventilation, and even such losses can occur if they are not properly stored during short-term accumulation. Therefore, the drying of grain is of great significance. Existing drying equipment often requires an additional moisture detector to detect the degree of drying of the grain in real time, while the existing resistive moisture detector is usually embedded in the grain of the dryer and is easily interfered by the external environment. And because the full seeds and the dried seeds are mixed together in the drying process, it is difficult to control the fullness of the seeds to be tested during the moisture dete...

AI Technical Summary

Problems solved by technology

Existing drying equipment often requires an additional moisture detector to detect the drying degree of the grain in real time, while the existing resistive moisture detector is usually buried in the grain of the dryer, which is easily disturbed by the external environment

And because full seeds and shriveled seeds are mixed together in the drying process, it is difficult to control the fullness of the seeds to be tested during the moisture detection process, and the moisture content of seeds with different fullness levels is also different after the same drying process Therefore, this brings great difficulties to the detection of seed moisture
