Full-automatic unattended grain assay system

Abstract

The invention discloses a full-automatic unattended grain assay system, comprising a computer, a PLC (programmable logic controller), a sample conveying unit, a sample dividing unit, a sample divisionpackaging unit, a QR (quick response) code management unit, an alarm unit, a volumetric weight and moisture detection unit and an impurity unsound kernel automatic detection and extraction unit. Boththe PLC and the volumetric weight and moisture detection unit are connected with the computer. Butting with a sampling machine, sample mixing and dividing, sample reserving, packaging and marking, volumetric weight assay, moisture assay, impurity array, unsound kernel processing and auto-cleaning are performed in sequence; samples can never be changed, volumetric weight, moisture, impurity and unsound kernel assay results can never be altered; the full-automatic unattended grain assay system can be butted to a sampling machine system and a warehousing system; the full-automatic unattended operation with automatic sampling in grain warehousing and automatic assay result provision is achieved; extensibility is high; relationship grain is avoided; working efficiency is improved; manpower issaved; the national granary is guarded; it is also ensured that the economic income of ordinary grain selling people is never infringed.

Description

technical field [0001] The invention belongs to the field of grain testing, and in particular relates to a fully automatic unattended grain testing system. Background technique [0002] According to national conditions, our country has to make a large amount of grain reserves every year, or buy surplus grain from farmers at high prices to protect the interests of farmers. The manpower and material resources invested by the country every year are quite amazing, and the cycle is relatively long. The quality of grain has a considerable impact on the storage of grain, and may affect the storage of thousands of tons of grain due to a cart of poor-quality grain. It can be seen that in the process of grain purchase, laboratory testing is a very important link. There are many test parameters, but they can be roughly divided into: parameters that affect economic value, such as impurities, moisture, bulk density, imperfect grains, etc.; parameters that do not affect economic value, ...

AI Technical Summary

Problems solved by technology

Existing schemes rely on sensory testing, testing with single-parameter equipment, and testing with two-parameter equipment, but it is always necessary to operate the equipment and fill in the test results manually, which cannot ensure the authenticity and representativeness of the samples taken. Unable to put an end to human food, unable to prevent samples from being replaced; often missing important laboratory parameters that affect grain prices such as bulk density
