The operation principle that the present invention monitors suppression power is as follows:
Consult Fig. 1, an elastic spokes 26 in press wheel installs linear displacement transducer 5, when suppression power is zero, a spring 9 compression displacement amount is zero, and linear displacement transducer 5 is original state.When press wheel is advanced, spoke sleeve pipe 10 can move back and forth along support bar 8, now drive the shell reciprocal telescopic of the pull bar relative linear displacement sensor 5 of linear displacement transducer 5, the stroke of pull bar is consistent with the stroke of a spring 9 and No. two springs 11.A spring 9 and No. two spring 11 alternate compression, remember that a spring 9 compression displacement amount is △ L, No. two spring 11 compression displacement amounts are-△ L.A spring 9 compression displacement amount is that △ L is converted into analog signal by linear displacement transducer 5.△ L correspond to press wheel deflection, and the suppression power of deflection and press wheel is proportionate, and by recording multi-group data in advance, demarcating, can come into operation after having demarcated to the relation between a spring 9 compression displacement amount △ L and the suppression power of press wheel.
Timing signal measures suppression power by electronic scale, and electronic scale first horizontal positioned during measurement also returns to zero, and is vertically pressed on electronic scale by press wheel, and applies different pressure to press wheel; Be connected digital oscilloscope at signal acquisition with after treatment circuit, the signal magnitude that digital oscilloscope record suppression power is corresponding simultaneously.Suppression power is made to increase to gradually from zero during experiment maximum, measure 6 groups of data, power y and signal data x is suppressed by electronic scale and digital oscilloscope record, and functional relation y=f (x) of suppression power y and signal data x is obtained by the polyfit function in MATLAB, because deflection and suppression power are proportionate, setting up quadratic function can meet the demands.By the relational expression y=f (x) that obtains suppressing between the signal x corresponding to y and linear displacement transducer 5 by program downloads in a single-chip microcomputer 16, a single-chip microcomputer 16 operationally can according to being obtained by linear displacement transducer 5 and exporting corresponding suppression power y signal through the signal that sensing and processing circuit 15 is changed.
Because elastic spokes 26 two ends are connected with elastic steel sheet 27 and bearing block 3 respectively by hinged, when press wheel works, might not be the position immediately below central shaft 1 when a spring 9 compression displacement amount △ L is maximum, certain angle may be departed from.Once suppress power y so survey every 100ms during work, ask the maximum y once suppressing power y every 2s
max, ask once maximum suppression power y every 30s
maxmean value
, this mean value is considered as the suppression power of this period of time (30s) interior press wheel to ground.Be transmitted to data receiver and display unit (Figure 10) by wireless transmitter module 17, operating personnel's readable data, Real-Time Monitoring is carried out to the size of suppression power.
After accurate Real-time Obtaining suppression power, regulate suppression power according to suppression power size by the rubber sleeve of changing different press wheel or the press wheel of changing different size.Obtain suitable suppression power and can reduce macrovoid in soil while sowing, the evaporation reducing moisture makes preserving soil moisture, and seed and soil close contact can be made to be conducive to seed sprouting and growth.
