Anti-blocking device of intelligent online grain moisture meter

Abstract

The invention relates to the technical field of blockage prevention of grain moisture meters, in particular to an anti-blocking device of an intelligent online grain moisture meter, and the device comprises a case, a moisture meter body, a feeding cylinder and a controller; the moisture meter body and the feeding cylinder are fixedly connected to the interior of the case; one end of the feeding cylinder is communicated with the moisture meter body; a rectangular opening is formed in one side wall of the case; the other end of the feeding cylinder extends out of the rectangular opening, a sliding rod is fixedly connected to the inner wall of the feeding cylinder, and an annular plate is slidably connected into the feeding cylinder; the annular plate is in sliding connection with the slidingrod; the annular plate is driven by a motor to scrape the inner wall of the feeding cylinder, and meanwhile, the annular plate is opened and matched with a baffle plate under the action of airflow and materials, so that the cleanness of the inner wall of the feeding cylinder in the moisture meter body is ensured, and the blockage of the feeding cylinder and the influence on the use of the moisture meter body due to adhesion of caked materials to the inner wall of the feeding cylinder are prevented; and the use stability of the moisture meter body is improved.

Description

technical field [0001] The invention relates to the technical field of anti-blocking of grain moisture meters, in particular to an anti-blocking device of an intelligent online grain moisture meter. Background technique [0002] my country is the world's largest producer and consumer of grain. However, in my country, the loss rate reaches 18% after the grain is harvested through threshing, drying, storage, transportation, processing, and consumption, which far exceeds the standard value set by the Food and Agriculture Organization of the United Nations. 5%. Grain moisture is an important factor affecting grain quality, and it is also an important indicator that must be detected in grain storage, purchase, processing, and transportation. If the moisture content of the grain is too high, it will cause the grain to rot and rot during storage or transportation. Drying is the most effective way to reduce the rot and spoilage of the grain due to the high moisture content. Substan...

Problems solved by technology

If the moisture content of the grain is too high, it will cause the grain to rot and rot during storage or transportation. Drying is the most effective way to reduce the rot and spoilage of the grain due to the high moisture content. Substances affect the nutritional content and quality of grains, so it is very important to accurately detect the moisture content of grains; due to the lack of existing technology, after long-term use of moisture detectors, grains, impurities and mud will stick to the surface after agglomeration On the inner wall of the feeding cylinder, which will cause the clogging of the feeding cylinder, which will affect the use of the moisture detector

[0003] In the prior art, there are also some technical solutions about the anti-blocking device of the intelligent online grain moisture meter. For example, a Chinese patent with the application number CN201410332954.2 discloses an online grain moisture meter, which includes a detection circuit, Rotary driving device, the output end of the rotating driving device is connected to the screw shaft, and a screw sleeve is arranged outside the screw shaft; Diameter section, screw section and optical axis section, the screw sleeve is covered outside the screw section and the optical axis section, the inner side of the screw sleeve is insulated and connected with carbon brushes, the upper side of the screw sleeve is provided with a hopper, and the reduced diameter section is inserted into the center of the ring electrode and set In the circular hole, there is an annular discharge channel between the reduced diameter section and the circular hole; the annular electrode and the screw shaft are connected to the detection circuit as two electrodes for measuring resistance; a temperature sensor is provided on the screw sleeve; The technical solution fully squeezes the grain to make it evenly distributed between the electrodes, making the collected measurement signal more scientific and real, and can measure the moisture of the grain quickly, accurately and in real time; , the grains, impurities and mud will stick to the inner wall of the feeding cylinder after agglomeration, which will cause the feeding cylinder to be blocked and affect the use of the moisture detector, thus causing the limitations of the solution
