Cereal on-line moisture automatic tester

Abstract

A cereal on-line moisture automatic tester contains a sampling mechanism-connected electrical control device installed inside a housing. A sampling mechanism comprises a device seat. A motor is installed at one side of the device seat. The motor drives a driving shaft by a speed change gear. The driving shaft drives a driven shaft by a gear. The driving shaft and the driven shaft are positioned inside a device chamber at another side of the device seat. The driving shaft is provided with a first pinch roller, a storage separator plate and a dredge impeller. The driven shaft is provided with a second pinch roller, a flaring feed inlet of the device chamber and a separator plate swinging groove. The storage separator plate drives the driving shaft to carry out reciprocating swing inside the separator plate swinging groove. The dredge impeller rotates with the driving shaft. The outer walls of the first pinch roller and the second pinch roller are respectively provided with rough particles and grooves. There exists a gap between the first pinch roller and the second pinch roller. During the relative rotation process of the first and second pinch rollers, cereal passes through the gap. The driving shaft and the driven shaft are respectively provided with a moisture receiver electrode slice which is connected with a socket. The socket is connected with the electrical control device through a lead.

Description

technical field [0001] The invention relates to an automatic on-line moisture tester for grain, which belongs to grain testing instruments. Background technique [0002] Grains (including rice, wheat, corn, sorghum, etc.) often need to be tested for moisture content when drying, purchasing and warehousing, so as to avoid mildew due to high moisture content. In the original technology, the methods for detecting the moisture content of grains are electric heating box drying method, capacitance method, probing type, etc. The drying method is to dry the grain after sampling, and use the weight lost by the grain after drying to compare with the drying method. The ratio of the weight of the sample before drying is used to determine the moisture contained in the grain; the capacitance method is to measure the grain as the medium of the capacitor, which takes a long time and the operation is complicated; the penetrating grain moisture analyzer adopts the method of separating the ele...
