Description
The utility model relates to the automatic detection of cotton moisture content in the unginned cotton acquisition system, belongs to unginned cotton automatic purchase equipment technical field.
The purchase of unginned cotton is a complexity and the technical very strong work that is difficult to grasp, the enthusiasm that the index of unginned cotton purchase and purchasing efficiency directly affect the cotton grower, thus also be related to development and national economy.The purchase of unginned cotton detects generally to be had ginning outturn to detect, contain assortedly to detect, grade is determined, length and water content detection.Water content detection wherein is now many, and this instrumentation mode is that hand pointer is determined pressure type with Y412A type cotton moisture content analyzer, and general pressure is 75Kg, and this hand operation must cause its inefficiency, and it is low to detect precision; In addition, Y412A type cotton moisture content analyzer, it must be quantitative requiring tested gined cotton, gets 50g at every turn, this has just limited the automation integrated operation of purchase.Because unginned cotton ginning outturn difference, 1kg unginned cotton can shut out 320g-420g gined cotton, if by the automated system Y412A type ice detector of once gined cotton that shuts out all being packed into, then surpass its 6 times of limiting the quantity of, resistance is difficult to too greatly measure; In addition, because gined cotton amount difference, its resistance is also different, and existing ice detector just can't solve this difficult problem on principle.
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of cotton moisture content automatic tester is provided, and gined cotton can be detected by non-quantitative automatically, the The data MICROCOMPUTER PROCESSING, and rapidly relevant data is shown on screen.
Cotton moisture content automatic tester of the present utility model mainly contained for following four most of compositions:
1. feed cotton pair roller.
2. the positive and negative pole plate of band convex reaches gined cotton case fixed, moving door.
3. the automatic compressing mechanism of forming by guide rail, leading screw, torque motor of gined cotton.
4. the A/D converter that links with gined cotton case positive and negative electrode.
The designed cotton moisture content automatic tester primary structure characteristics of the utility model are as follows:
1. the radians such as positive and negative pole plate on fixed, the moving door protrude to the centre, have shortened the two-plate spacing, have increased gined cotton density.To guarantee accuracy of measurement.
2. employing rolling guide, ball-screw to reduce advance resistance, guarantees moving door flexibly.
3. drive leading screw with torque motor, make it to keep the gined cotton constant density, with the accuracy that guarantees to measure.
4. adopt special pair roller that gined cotton is clamp-oned the gined cotton case, make to reach certain density in the case, reduce the stroke that torque motor drives leading screw, increase work efficiency.
The new principle method that realizes the purpose of this utility model institute foundation is the ginning outturn compensatory approach.At first measure the variation of gined cotton amount and the relation curve of resistance variations, determine the ginning outturn offset data.Concrete grammar is: the ginning outturn with 35% is a standard, the every increase by 1% of ginning outturn, and getting actual measurement moisture increases certain value, every minimizing 1%, moisture deducts certain value.
Fig. 1 is the utility model structural representation.Wherein, 1. gined cotton case, 2. negative pole, 3. negative plate, 4. fixed door, 5. anodal, 6. drain cotton plate is 7. fed cotton pair roller, 8. positive plate, 9. moving door, 10. temperature sensor, 11. rolling bearings, 12. guide rails, 13. leading screw, 14. torque motors, 15. gear pairs, 16. electromagnet, 17. travel switch, 18.A/D converter, 19. pins, 20. support bars, 21. lever, 22. screws, 23. weigh
The utility model is described in further detail below in conjunction with accompanying drawing.
The gined cotton that trial ginning machine shuts out is collected through collecting cotton dust cage, flows into through drain cotton plate 6 and feeds cotton pair roller 7, feeds cotton pair roller 7 gined cotton is fed gined cotton case 1, and this pair roller can all be clamp-oned the gined cotton case with 320g-420g gined cotton, and makes gined cotton reach certain density. After sample gined cotton all feeds, staring torque motor 14, motor 14 drives leading screw by gear pair 15, and leading screw 13 is fixed on the body, leading screw moves forward guide rail 12 by driving screw 26 during motion, with 12 rolling bearings 11 guide rail 12 is located at four direction. One end of guide rail 12 is welded with moving door 9, is fixed with temperature sensor 10, positive pole 5 and positive plate 8 on the moving door 9, and moving guide rail advances Gined cotton in the time compression gined cotton case makes it density and increases gradually. When density reached certain appropriate value, gined cotton equaled the maximum thrust that torque motor produces by leading screw along the expansive force of guide rail direction, and at this moment, torque motor is stall just. Close and open the door 17, the compression gined cotton between positive pole 5 and the negative pole 2 has a little electric current, and A/D converter is calculated to get the gined cotton water content according to the relation of permanent density compression gined cotton contained humidity and gined cotton resistance.
Owing to the compression gined cotton resistance of same moisture again variation with temperature change, so temperature sensor 10 will measure temperature, revise according to existing relation curve.
When the gined cotton ginning outturn changes, guaranteeing under the same compression gined cotton density conditions, owing to the ginning outturn increase and decrease makes two-plate 3 and the to some extent increase and decrease of 8 distances. The direct relation of A/D converter 18 is tried to achieve. Because the variation that the both positive and negative polarity change of distance has a resistance, A/D converter 18 moisture of surveying and actual moisture are slightly variant. This difference is carried out the ginning outturn compensation deals according to gined cotton weight number by existing ginning outturn-sensitivity curve.
Gined cotton case 1 below is provided with a leverage, and pin 19 pins of lever 21 1 ends are on fixed door 4, and the lever other end is electromagnet 16, and lever links by support bar 20 and gined cotton case 1. After A/D converter has been surveyed the resistance of gined cotton, start lever by electromagnet pin is left behind, fixed door 4 is opened, and gined cotton is pushed away to fall into and weighs.
Above-mentioned leading screw is ball-screw, and guide rail is rolling guide. It is identical that the positive/negative plate protrusion opens radian, and convex protrusion partly is positioned in the middle of the pole plate, and opening radian is 100-180 °.
Embodiment:
Accompanying drawing is the utility model most preferred embodiment.Wherein leading screw 13 is ball-screws, and guide rail is a rolling guide.It is 150 ° that positive/negative plate protrudes radian.
