Abstract
A kind of grain moisture content fast detecting instrument of energy fast detecting grain moisture content, it is made up of computer technology, microwave technology, weight sensing technology, solved can not the fast detecting grain moisture content a difficult problem, the measuring error that detects wheat, soybean, paddy rice is≤± 0.2%, and corn is≤± 0.5%.Designed microwave detecting device, the microwave emitter of being made up of microwave oscillator and microwave antenna, microwave channel, sample box, microwave receiver, the weight transmitter be made up of microwave detector and microwave antenna are formed.The method that has adopted the emission of microwave variable, microwave quantitatively to receive is measured sample under the microwave receiving state of the best.Utilize scale conveyors to measure the unit weight of same sample simultaneously at the detection grain moisture content, by the different problems that cause the error of sample contained humidity of unit weight, realized a tractor serves several purposes by the computing machine correction.This device volume is little, in light weight, is easy to carry.
Description
Affiliated technical field
The utility model relates to a kind of grain moisture content detection device, especially can fast detecting go out various grains different phase moisture and can directly detect the device that grain unit weight detects.
Background technology
At present, the grain moisture content detection method is used gravimetric method usually, and gravimetric method also claims seasoning, and under certain test conditions, the combination of moisture and volatility breaks away from the sample body and the mistake of escaping in the sample, loses thing weight and promptly measures the amount of the amount of alleviating of front and back sample as moisture.
Though gravimetric method is a kind of classical standard method, and is widely used, and when using this method sample is had certain requirement, the sample survey cycle, long (generally needing more than two hours) can not fast detecting.The method of energy fast detecting grain moisture content is an electrical measuring method.At present, comparatively common have two kinds of resistance-type and condenser types.
The resistance-type analytic approach: this method is to measure moisture by the corresponding resistance change of the variation of working sample composition especially water cut.
The condenser type analytic approach: this method is can represent moisture in the sample by working sample electric capacity (amount of expression specific inductive capacity), and these two kinds of methods can not accurately detect high moisture grain.
Summary of the invention:
Bigger than normal and can not detect this difficult problem of the Northeast's high moisture grain (as corn) in order to overcome quick measurement grain moisture content measuring error; the utility model provides a kind of grain moisture content fast detecting instrument; this method can not only be measured grain moisture content (comprising high-moisture corn) fast can make paddy rice, wheat, soybean detect error≤± 0.2% under home, and corn detects error and is≤and ± 0.5%.
The technical scheme that the novel technical solution problem of present technique is adopted is: detect grain moisture content with the Microwave Measurement method, realize intelligent with computer technology, the weight that records grain in the sample box with scale conveyors is the machine volume of box per sample as calculated again, calculates the unit weight of sample.Computing machine is by the error of Intelligent treatment correction owing to the different caused sample moisture of sample unit weight.
Realize Microwave Measurement to design one can the fast detecting grain moisture content microwave detecting device, the microwave emitter that this device is made up of microwave oscillator and microwave antenna, microwave channel, sample box, microwave receiver, weight transmitter and the housing be made up of microwave detector and microwave antenna are formed.
Microwave channel is not only fixedly microwave emitter, the device of microwave receiver and insertion sample box, and determined distance between microwave emitter and the microwave receiver by it, this distance must guarantee to be the relation of three multiples of microwave wavelength (depart from these three multiples and concern that error can appear in Microwave Measurement), and satisfy what needs of detected sample, microwave channel is designed to 80 (length) * 80 (wide) * 115 (height) mm rectangle band substrate boxes, leave 40 * 60mm oblong aperture in the corresponding both sides of box body, little device that is launched sends microwave and is received by microwave receiver by little sample that is passed in the sample box by the passage slot, and it be quantitatively reception that this programme adopts microwave receiver.When microwave that microwave emitter sends by microwave channel in sample in the sample box decay, this decay and sample moisture have certain corresponding relation.Computing machine satisfies microwave receiver definite value power requirement according to the emissive power of the size adjustment microwave emitter of sample microwave numerical value decay in this programme, how much is come to determine the moisture value of sample by the emissive power of adjusting microwave emitter.
Fix a scale conveyors in housing base plate central authorities, again microwave channel is fixed on the scale conveyors, when will be less than microwave channel xsect 80 * 80mm, being designed to 78 * 78 * 125mm greater than rectangle sample box this programme of the height of microwave channel height inserts in the microwave channel, this device is available Microwave Measurement grain moisture content, can record the weight of the sample in the sample box again, more as calculated machine per sample the weight of the volume of box and sample calculate the unit weight of sample.
Because the difference of grain variety, particle shape is widely different.The packing of pouring the grain in the sample box into has a significant impact detecting the grain moisture content error, go out the unit weight of sample by COMPUTER CALCULATION, margin of error by computing machine correction sample contained humidity, sample has not only solved the measuring error problem by the different caused contained humidities of unit weight, this measurement data of unit weight of institute's test sample product also is provided for the user simultaneously, has realized the demand that multi-functional machine detects.
The beneficial effects of the utility model are, this device can the moisture 8%-40% of fast detecting various grains, especially the detection error to high-moisture corn reach≤0.5%, the detection error of soybean, wheat, paddy rice is≤0.2%, this device has had both the function that detects grain unit weight, network enabled simultaneously.
