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

The invention relates to an on-line grain moisture meter feeding and impurity removal cleaning device. It includes a pair of counter-rotating horizontal power output shafts installed on both sides of the inlet of the moisture meter body. The axial direction of the output shaft is installed with a rotatable cleaning scraper and a screw conveyor roller (commonly known as the conveyor screw conveyor) from the inside to the outside. Roller), the helix of the screw conveying roller has at least one miscellaneous groove, the cleaning scraper has a radial cutting edge, the two spiral conveying rollers mesh with each other at the staggered position corresponding to the miscellaneous groove, and the body of the moisture meter corresponds to the two auger conveying The position above the meshing position of the material roller is installed with a block for removing impurities. The middle part of the block for removing impurities extends toward the axial direction of the output shaft to form a wedge-shaped extension above the mesh of the screw feed roller. The wedge-shaped extensions form a The miscellaneous side inclined surface above the meshing part of the feeding roller can effectively remove all kinds of doped impurities in the material, clean the feed inlet in real time, prevent blockage, avoid abnormal sampling values of the moisture meter, and improve the accuracy of the measured values Spend.
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 ...
