Abstract
The utility model discloses a grain moisture detector which comprises a housing and a measurement cylinder vertically arranged inside the housing. The measurement cylinder comprises a metal inner cylinder and a metal outer cylinder, which form a capacitance sensor; a temperature sensor is arranged on the metal outer cylinder; a weigh sensor is arranged at the bottom of the metal outer cylinder; a fixed cover is arranged between the housing and the measurement cylinder; a measurement main control circuit is arranged at the bottom of the housing and connected with the metal inner cylinder and the metal outer cylinder respectively; the measurement main control circuit comprises an alarm module; and the alarm module is connected with a loudspeaker. The grain moisture detector is suitable for on-site rapid moisture detection of grains and can give an alarm in case of abnormal moisture, and besides, the grain moisture detector has the advantages of simple structure, reasonable design and good practicability.
Description
Technical field
The utility model relates to a kind of Moisture Meter, is specifically related to a kind of grain moisture content instrument.
Background technology
The moisture of grain is the necessary component of grain cell, and it is necessary still to keep the vital movement of grain cell own and using character, and therefore, Measurement for Grain Moisture Content can not be too high, can not be excessively low, and it is suitable to keep.Moisture is too high, and weight increases the weight of, waste transport power and capacity, and cause that easily grain generate heat, goes mouldy, infested and other biochemical reaction, to such an extent as to grain is gone bad; Moisture is excessively low, can destroy its organic substance, damages dry, reduces weight, so the detection of grain moisture content is the main basis of safe storage.Recent two decades comes, and has researched and produced various moisture tellers both at home and abroad in the hope of replacing expense electricity consuming time, the unsuitable on-the-spot traditional oven method that uses.The restriction of the examined principle of present moisture teller, the limitation of detection is larger, and ubiquity detects the problems such as the large and poor repeatability of error, fails to obtain user's approval and the approval of national departments concerned.Therefore a kind of on-the-spot quick grain moisture content instrument that the moisture of grain is detected that is suitable for need to be arranged.
The utility model content
The purpose of this utility model is to provide a kind of grain moisture content instrument, and described grain moisture content instrument is suitable for on-the-spot quick moisture to grain and detects, and can unusual moisture make warning.
For achieving the above object, the technical solution of the utility model is a kind of grain moisture content instrument of design, comprise housing, be provided with perpendicular measuring cylinder of putting in the housing, measuring cylinder comprises metal inner core and the metal outer cylinder of a formation capacitive transducer, be provided with temperature sensor at metal outer cylinder, be provided with LOAD CELLS in the bottom of metal outer cylinder, be provided with fixed cap between measuring cylinder and the housing; Housing bottom also is provided with respectively the measurement governor circuit that is connected with metal outer cylinder with the metal inner core, measures governor circuit and comprises alarm module, and alarm module is connected with loudspeaker.
Preferably, described housing bottom also is provided with control panel, power interface, USB interface and printer interface.
Preferably, be provided with LCD display and control knob on the described control panel.
Preferably, described measurement governor circuit also comprises temperature measurement circuit, weighing circuit, usb circuit and printer interface circuit.
Preferably, the bottom of described housing also is provided with to place the battery case of dry cell.
During use, with the tested grain blanking barrel of packing into, grain evenly falls between the metal inner core and metal outer cylinder of measuring cylinder, temperature sensor and temperature measurement circuit are measured the temperature of grain, LOAD CELLS and weighing circuit are measured the weight of tested grain at any time, the measurement governor circuit is judged as blanking and finishes after weight is stable, difference along with tested grain moisture content, the capacitance of the capacitive transducer that metal inner core and metal outer cylinder consist of is also along with variation, moisture/freq converting circuit is converted to the capacitance variations of capacitive transducer the variation of frequency, and the frequency that will change exports the measurement governor circuit to, measuring governor circuit processes this frequency, and compare with the moisture curve that is stored in the nonvolatile memory, obtain corresponding moisture, the weight difference before and after the weighing circuit measurement blanking obtains the weight of tested grain, carries out accordingly the weight correction of moisture, carry out again temperature compensation, the radix correction obtains revised moisture value at last.
As unusual moisture value appears, and to measure governor circuit and send signal to alarm module, alarm module drives loudspeaker and sends warning.
Advantage of the present utility model and beneficial effect are: a kind of grain moisture content instrument is provided, described grain moisture content instrument is suitable for on-the-spot quick moisture to grain and detects, and can unusual moisture make warning, and this grain moisture content instrument is simple in structure, reasonable in design, have good practicality.
