Embodiment Construction
[0025] Below in conjunction with accompanying drawing, the present invention will be further described:
[0026] combine Figure 1-Figure 9 As shown, this fast detection device for grain moisture based on a gravity sensor is controlled by a single-chip microcomputer to control the shifting of the stepping transmission mechanism to realize the cyclic switching of the feeding station 9, the detection station 10, and the removal station 19 without interruption. The testing work is carried out continuously, and the feeding station 9, the testing station 10, and the removing station 19 do not affect each other. Therefore, the present invention can accommodate three kinds of samples at the same time and automatically test the moisture value of the material in sequence. Feeding station 9, detection station 10, and material removal station 19 are all arranged in the frame, and the detection mechanism is provided with a heating mechanism, a support frame 2, a single-chip microcomputer ...

The invention relates to a quick detection device for grain moisture based on a gravity sensor, which is controlled by a single-chip microcomputer to shift the position of a stepping transmission mechanism to realize the cyclic switching of three stations: the feeding station, the detecting station and the removing station. The material station, detection station, and material removal station are all set in the frame. The detection mechanism is equipped with a heating mechanism and a support frame, and the gravity sensor is installed under the support frame; the material removal station is equipped with a cam track and a material removal plate; the moving glass When the cover mechanism and the moving tray mechanism move to the material removal station, they move up along the cam track, and the material removal plate scrapes off the materials on the moving tray; when the moving glass cover mechanism and the moving tray mechanism move to the detection station, the heating mechanism Located directly above the glass barrel, the third roller just corresponds to the support frame; the gravity sensor is connected to the single-chip microcomputer, and the heating mechanism is connected to the single-chip microcomputer. The invention realizes the cyclic switching of the three stations of material feeding, heating measurement and material removal, can continuously test without interruption, and satisfies the requirements of accurate and rapid measurement.
Description
technical field [0001] The invention relates to the technical field of grain drying equipment, in particular to a quick detection device for grain moisture based on a gravity sensor. Background technique [0002] The detection of grain moisture is an indispensable and important link in the links of purchase, storage, transportation, processing, trade, etc. Its accurate measurement plays a decisive role in grain quality grading and grain processing. The national standard method for grain moisture detection is the oven method. This method is accurate, but time-consuming and power-consuming. The average test time for each sample is 2-3 hours or even longer. It is only suitable for professional laboratories and cannot satisfy Rapid on-site moisture detection is required; the actual performance of the existing online moisture measuring instrument is not ideal, the accuracy is low, and it is easily affected by environmental factors, grain types, and physical parameters, making the...
