Problems solved by technology
[0005] In order to make up for the shortcomings of the existing technology, the replacement steps of the rolling wheel are complicated, waste of manpower and material resources, and the vibration of the adjustable rolling wheel in the process of crushing the grain after the adjustment is completed. The low precision of grain crushing and poor crushing uniformity lead to moisture detection accuracy. Low problem, a kind of high-precision resistive grain intelligent moisture detector proposed by the present invention

The invention belongs to the technical field of moisture detectors, and particularly relates to a high-precision resistance type intelligent moisture detector for the grain. The high-precision resistance type intelligent moisture detector for the grain comprises a detector, an adjusting device and a controller, wherein the adjusting device comprises a first adjusting box, a second adjusting box, afirst rotating roller, a second rotating roller, an electric push rod, a motor and a worm; first sleeve rings are rotatably connected to the surfaces of the first rotating roller and the second rotating roller in a sleeving way; a rubber layer is fixedly connected to the side wall of a groove of an inserting rod; and an air passage is arranged in the rubber layer. According to the high-precisionresistance type intelligent moisture detector for the grain provided by the invention, the gap between smashing rollers is intelligently adjusted, different smashing degrees of the grain are adjustedappropriately, the adjusting accuracy is high, the mechanization of the adjusting process is realized, the problems that the step of manually replacing a smashing roller to drive is complicated and manpower and material resources are wasted are solved, meanwhile, the vibration frequency and the vibration amplitude of the smashing rollers can be reduced, and the grain smashing precision and the detection precision of the moisture detector are improved.
Description
technical field [0001] The invention belongs to the technical field of moisture detectors, in particular to a high-precision resistance type intelligent moisture detector for grain. Background technique [0002] Grain moisture detection technology is generally divided into direct method and indirect method. The direct method is to directly remove the moisture in the grain by drying or chemical methods, and detect the absolute moisture content of the sample. The direct method of moisture detection has high detection accuracy and is suitable for laboratory detection. The disadvantage is that the detection time is relatively long, and fast and online monitoring cannot be realized, so it is difficult to meet the speed and continuous requirements of modern production. The indirect method is through the detection of physical quantities related to moisture, mainly including resistance moisture determination, nuclear magnetic resonance method, capacitive moisture determination, and...
