Anti-ash-deposition brush for cleaning runner wheel in resistance-type online grain moisture meter

Abstract

The invention discloses an anti-ash-deposition brush for cleaning a runner wheel in a resistance-type online grain moisture meter. The anti-ash-deposition brush comprises a brush structure and a scraper, and the brush structure and the scraper are fixedly installed together through connecting bolts. The brush structure includes a brush holder and brushing hair, one end of the brushing hair is mounted on one surface of the brush holder, and a rectangular groove with openings on three surfaces is formed in the adjacent surface, on the mounting surface of the brushing hair, of a mounting seat. Afirst threaded hole is formed in the bottom surface of the rectangular groove, the two ends of one surface provided with the rectangular groove are provided with trapezoidal tables, and certain distances are reserved between the trapezoid tables and the rectangular groove to form a frame platform. The scraper includes a baffle, frame plates and arc-shaped plates, a second threaded hole is formed in the baffle, the frame plates which are arranged relatively parallel are installed on one end of the baffle, and the two frame plates are provided with the arc-shaped plates. According to the anti-ash-deposition brush for cleaning the runner wheel in a resistance-type online grain moisture meter, large-grain grains and powder grains adhered on the runner wheel can be removed in time, grain powderis prevented from filling tooth grooves on the runner wheel, and the working efficiency of the grain moisture meter and the accuracy of the measurement results are improved effectively.

Description

technical field

[0001] The invention belongs to the field of grain moisture meters, and in particular relates to an anti-dust brush used for cleaning the inner roller of a resistance online grain moisture meter. Background technique

[0002] With the development of scientific research and the progress of production technology, the quantitative analysis of moisture has been listed as one of the basic items of physical and chemical analysis of various substances, and as an important quality index of various substances. The moisture content of grain is an essential part of grain cells. In order to maintain the quality of grain, the moisture content in grain should be kept at an appropriate level. Therefore, when storing large quantities of grain, it is necessary to measure the moisture content in grain. And control the moisture content in the grain at a reasonable level through subsequent processing.

[0003] The currently used dry weighing method will take up a lot of time wh...
