Problems solved by technology

On the one hand, these impurities are easy to entangle and block the feeding and sampling mechanism of the moisture meter, causing damage to the moisture meter; The dielectric constant sampled by the moisture meter causes the basic data required to calculate the grain moisture to be abnormal, making the moisture value output by the moisture meter inaccurate

Abstract

The invention relates to a conveying and impurity-removing device of an on-line grain moisture meter. The conveying and impurity-removing device comprises a pair of horizontal power output shafts, wherein the horizontal power output shafts are arranged on two sides of a feed opening of a moisture meter body and rotate in opposite directions; rotatable impurity-removing scrapers and screw conveying rollers are mounted from inside to outside in the axial directions of the horizontal power output shafts; at least one impurity-removing groove is formed in the screw of each screw conveying roller; the impurity-removing scrapers have radial cutting edges; the two screw conveying rollers are meshed with each other in such a way that the corresponding impurity-removing grooves are staggered; an impurity-removing stop block is mounted on the moisture meter body in a position above the meshing point of the two screw conveying rollers; the middle of the impurity-removing stop block extends axially to the horizontal power output shafts to form a wedge-shaped extension end above the meshing point of the screw conveying rollers; and inclined impurity-separating side surfaces, which are located above the meshing point of the screw conveying rollers respectively, are formed on the wedge-shaped extension end. According to the conveying and impurity-removing device, various impurities doped in a material can be removed effectively, the feed opening is cleaned in time, blockage is prevented, the grain moisture meter is free of an abnormal sampling value, and the precision of a measured value is improved.

Description

technical field [0001] The invention relates to an impurity removal and cleaning device, in particular to an online grain moisture meter feeding impurity removal and cleaning device, which belongs to the technical field of agricultural machinery. Background technique [0002] Grain drying is an important link in the processing of agricultural products. The automatic control of the grain drying process is of great significance to ensure the quality of grain after drying, reduce the cost of drying operations and improve productivity. Fast and accurate online measurement of grain moisture is the key to automatic control of the grain drying process [0003] As far as the applicant knows, the existing online moisture meters are divided into two types: resistive type and capacitive type, but no impurity removal and cleaning device is added to the two types of moisture meters. When in use, the materials in the drying equipment are mixed with a large amount of dust, straw and awns ...
