Abstract
The utility model relates to a cotton water measurement instrument. The water content of cotton under the natural state can not only affect physical and chemical properties and mechanical properties of fibers, but can also affect the weight of the cotton, so the cotton must have the density with a fixed value during the measurement to ensure the accurate measurement of the water content; at present, the similar measurement instrument ensures the density by the compression amount of a spring, but the accuracy thereof is inevitably affected along with the reduction of the coefficient of stiffness of the spring. The technical proposal of the utility model is as follows: a display panel is fixed on a box body, a display screen; a control panel and a circuit board are arranged on the display panel; a fixed polar plate is transversely inserted in the middle of the box body; a base is fixed at the lower part of the box body; a transmission shaft is hinged on the base; a gear is fixed in the middle part of the transmission shaft and meshed with a rack which is arranged in a sleeve; the upper end of the sleeve is connected with a movable polar plate; a humidity sensor is fixed below the circuit board, and a pressure sensor is embedded in the sleeve. The test pressure of the cotton water measurement instrument is constant and accurate and is not affected by the environmental humidity.
Description
Technical field
The utility model relates to a kind of cotton moisture content surveying instrument, particularly has the cotton moisture content analyzer of pressure detection control device and humidity detector, belongs to gauging instrument.
Background technology
Cotton all contains moisture under the natural air state, the physicochemical property and the mechanical mechanics property that how much not only affect cotton fiber of its water cut, particularly directly affect the weight of cotton, and the weight of cotton is the leading indicator of transaction, the standard moisture of national regulation cotton is 8.5%, and the moisture absorption of cotton is diffusing moist very strong, and for guaranteeing the accurate of cotton transaction index, the water cut that accurately measures cotton is vital.The cotton that water cut is different has different electric conductivities, and is moisture many, conducts electricity very well, moisture few, and poor electric conductivity adds certain DC voltage to it, just can detect the water cut of cotton by the resistance of measuring cotton.And to detect cotton moisture content value accurately and reliably, and must guarantee that cotton has the packing of definite value, promptly requiring two-plate is 735N to the level pressure power of cotton, the more stable and easy operation of numerical value that this force value detects.
The similar detecting instrument that generally uses is to have consistent decrement to guarantee in test process by spring for to stablize this certain value pressure of 735N at present, with the calibration of pressure detection instrument.Stamp round dot as calibration position in pointer indication position when the pressure between the two-plate is 735N, promptly the suffered thrust of pole plate is that 735N begins test when pointer points to the round dot position.But this operating process is because the position of pointer need be with estimating, and along with spring pushes increasing of number of times, the coefficient of stiffiness of spring must decrease, though the indication of pressure pointer is on round dot, but actual pressure has influenced precision of test result less than 735N; Secondly, the humidity of test environment is also very big to the measurement result influence, and cotton measured value when ambient humidity is big of same regain is also big, because ambient humidity changes at any time in one day, so directly influenced the accuracy of measuring the cotton water cut.
Summary of the invention
To be that design is a kind of can not influenced by ambient humidity and can keep the stable cotton moisture content analyzer of gaging pressure the purpose of this utility model.
The technical solution of the utility model is:
Fixed display panel on casing, display screen is housed on the display panel, console panel and circuit board, cell apparatus is on the base plate of casing, the horizontal centre that is inserted in casing of fixed polar plate, casing is divided into two parts up and down, base is fixed on the bottom of casing, transmission shaft is hinged on base, gear is fixed on the middle part of transmission shaft, and meshes with the tooth bar that is loaded in the sleeve, and operating grip is contained in outside the casing and with transmission shaft and links to each other, the upper end of sleeve is connected with movable pole plate, space between movable pole plate and the fixed polar plate forms and puts cotton chamber, fixing humidity sensor below circuit board, setting-in pressure transducer in sleeve.
The utility model is not subjected to the influence of ambient humidity, and test pressure is constant accurately, and test process intuitively accurately and reliably.

Description of reference numerals is as follows:
Embodiment
Below in conjunction with the embodiment accompanying drawing the utility model is done and to be described in further detail:
Fixed display panel 2 on casing 1, display screen 14 is housed on the display panel 2, console panel 15 and circuit board 3, battery 5 devices are on the base plate of casing 1, the fixed polar plate 6 horizontal centres that are inserted in casing 1, casing 1 is divided into two parts up and down, base 16 is fixed on the bottom of casing 1, transmission shaft 17 is hinged on base 16, gear 9 is fixed on the middle part of transmission shaft 17, and with tooth bar 10 engagements that are loaded in the sleeve 12, operating grip 13 is contained in outside the casing 1 and with transmission shaft 17 and links to each other, the upper end of sleeve 12 is connected with movable pole plate 8, movable pole plate 8 is put cotton chamber 7 with the space formation between the fixed polar plate 6, fixing humidity sensor (4) below circuit board (3), setting-in pressure transducer (11) in sleeve (12).
When using the utility model, get about 50 gram cottons, evenly put into the cotton chamber of putting between fixed polar plate and the movable pole plate, the rotating operation handle, gear and then rotates and drives the tooth bar reach, movable pole plate is given in pressure transducer power transmission in the compression sleeve, movable pole plate reach compresses cotton, circuit is connected and is begun test when the pressure transducer detected pressures reaches 735N, the instant measures ambient humidity of humidity sensor, and the regain of measuring revised, more revised accurate numerical value being presented on the display panel, test process is finished.
