The operation principle that the present invention monitors suppression power is as follows:
Consult Fig. 1, in an elastic spokes 26 in press wheel, linear displacement transducer 5 is installed, suppression power is 1 o'clock, and No. one spring 9 compression displacement amounts are zero, and linear displacement transducer 5 is original state.In the time that press wheel is advanced, spoke sleeve pipe 10 can move back and forth along support bar 8, now drive the shell of the relative linear displacement transducer 5 of pull bar of linear displacement transducer 5 back and forth to stretch, 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 spring 9 compression displacement amounts are △ L, and No. two spring 11 compression displacement amounts are-△ L.Linear displacement transducer 5 is that △ L is converted into analog signal by spring 9 compression displacement amounts.△ L correspondence press wheel deflection, and the suppression power of deflection and press wheel is proportionate, and by recording in advance multi-group data, the relation between spring 9 compression displacement amount △ L and the suppression power of press wheel is demarcated, and after having demarcated, can come into operation.
Timing signal is measured suppression power by electronic scale, and when measurement, the first horizontal positioned of electronic scale zeroing, be vertically pressed in press wheel on electronic scale, and apply different pressure to press wheel; Be connected digital oscilloscope at signal acquisition with after treatment circuit, digital oscilloscope records signal magnitude corresponding to suppression power simultaneously.When experiment, make suppression power increase to gradually maximum from zero, measure 6 groups of data, record suppression power y and signal data x by electronic scale and digital oscilloscope, and obtain suppressing the functional relation y=f (x) of power y and signal data x by the polyfit function in MATLAB, because deflection and suppression power are proportionate, setting up quadratic function can meet the demands.To obtain suppressing relational expression y=f (x) between y and the corresponding signal x of linear displacement transducer 5 by program downloads to single-chip microcomputer 16, No. one single-chip microcomputer 16 can be exported corresponding suppression power y signal according to the signal that is obtained by linear displacement transducer 5 and change through sensing and processing circuit 15 in the time of work.
Because elastic spokes 26 two ends are connected with elastic steel sheet 27 and bearing block 3 respectively by hinged, in the time that press wheel is worked, when No. one spring 9 compression displacement amount △ L are maximum, might not be the position under central shaft 1, may depart from certain angle.So survey and once suppress power y every 100ms when work, ask the maximum y that once suppresses 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, carries out Real-Time Monitoring to the size of suppression power.
Accurately after Real-time Obtaining suppression power, regulate suppression power according to the large I of suppression power by the press wheel of changing the rubber sleeve of different press wheels or changing different size.Obtaining suitable suppression power can reduce the macrovoid in soil in sowing, and the evaporation that reduces moisture makes preserving soil moisture, can make seed and soil close contact be conducive to seed sprouting and growth.
