Multifunctional efficient grain moisture online detection device

Abstract

The invention discloses a multifunctional and high-efficiency grain moisture online detection device, which includes a control system and a measurement system; the further improvement lies in that the measurement system includes a measurement mechanism, a base assembly, a driving mechanism, and a feeding device; the base assembly includes an elastic adjustment mechanism, a screw Adjusting mechanism; the driving mechanism includes a deceleration motor, a gear transmission mechanism, a base plate, and a conductive reed. The gear transmission mechanism includes six gears meshing with each other, and the conductive reed is fixed on the base plate; There is a gap △, which is adjusted by the screw adjustment mechanism according to the size of the grain; the collecting and feeding device includes a collecting hopper and a grain feeder; a grain deflector is installed between the bottom of the grain feeder and the two electrode rollers, and the grain collected by the collecting hopper passes through the grain feeder The single grain is conveyed into the grain deflector and falls to the gap △ between the two electrode rollers. The invention has strong feeding capacity, reliable performance, and accurate moisture measurement, which is suitable for different grain moisture drying measurement requirements.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an online grain moisture detection device for a grain dryer. Background technique [0002] At present, the hoist of the low-temperature grain dryer is equipped with an instrument for online measurement of grain moisture, which is used to monitor moisture in real time and transmit data to the computer control panel. In the actual use process, there are the following problems: First, due to the large variety of grains, such as rice, wheat, corn, soybeans, sorghum, rapeseed, etc., the particle size is inconsistent, and the moisture meter in the prior art is due to the gap between the two rollers. The gap between them cannot be adjusted, and it cannot meet the needs of multiple varieties of grains at the same time. If you want to dry different varieties of grains, you must replace the moisture detectors corresponding to the varieties of grains, which increases the cost...

AI Technical Summary

Problems solved by technology

In the actual use process, there are the following problems: First, due to the large variety of grains, such as rice, wheat, corn, soybeans, sorghum, rapeseed, etc., the particle size is inconsistent, and the moisture meter in the prior art is due to the gap between the two rollers. The gap between them cannot be adjusted, and it cannot meet the needs of multiple varieties of grains at the same time. If you want to dry different varieties of grains, you must replace the moisture detectors corresponding to the varieties of grains, which increases the cost of use. Although some moisture meters do replace the rollers. Improvement in controlling the gap between the two rollers, but it is time-consuming and laborious, troublesome to replace, and improper operation directly affects the measurement accuracy

Even the grains of the same variety have different particle sizes. In addition, grains in different regions have large differences in size and hardness. The degree of crushing and crushing of the two metal rollers is different, and the grains are not completely crushed, which leads to the measurement process. It cannot be carried out in a stable and orderly manner, which will eventually lead to errors and inaccuracies in the collected resistance signals, which will have a great impact on the measurement results of the moisture content of the grain, resulting in inaccurate measured moisture data

[0003] The moisture meter in the prior art installs the two electrode rollers directly in the hoist of the dryer. Due to the unevenness of the grain falling in the hoist, sometimes the grain is insufficient or the grain is too concentrated, resulting in uneven rolling. , affects moisture monitoring, and also directly affects measurement accuracy
