As seen from Figure 1, Figure 2, the mechanical part of this automatic guiding device for tilless seeder of corn ridge comprises frame 6, leading truck 14 two parts.Leading truck 14 is connected with frame 6 by axle 11, and can under the effect of hydraulic pressure, rotate around axle 11, rely on the lead of revising the facility lower link that relatively rotates of the two in the operation process, and then revise direction of advance, the revolving force of leading truck 14 comes from hydraulic cylinder 3.Hydraulic cylinder 3 and hydraulic stem 2 thereof are two covers, be provided with about leading truck 14 respectively, and leading truck 14 and frame 6 are coupled together.Hydraulic stem 2 is connected with frame 6 by connector 8, and hydraulic cylinder 3 is connected with leading truck 14 by circular shaft 15; In actual production, also can adopt this connected mode: hydraulic cylinder 3 is connected with frame 6 by connector 8, and hydraulic stem 2 is connected with leading truck 14 by circular shaft 15.
This automatic guiding device for tilless seeder of corn ridge, before leading truck 14, be equipped with and visit fork 19 and the contactless angular displacement sensor 20 of WYH-AT-1, and composition with TMS320F2812DSP type control module 4 and hydraulic valve 7, wherein hydraulic valve 7 is by 4WRA6E10-10B24Z type electromagnetic proportional valve 22, S6P120 type check valve 23, DBW10-2-30-315 type electromagnetic relief valve 24 compositions such as grade, wherein check valve 23 is connected with fuel tank respectively with electromagnetic proportional valve 22, branch is connected an electromagnetic relief valve 24 between electromagnetic proportional valve 22 and the fuel tank, and electromagnetic proportional valve 22 is connected with hydraulic cylinder 3.
In the present embodiment, mainly with Ridge-till and No-till Corn Planter as embodiment, in the actual production, this auto-guider can be applied to other need facility to row in, the weeder in the corn field etc. for example.
As shown in Figure 3, program is at first carried out system initialization, comprises clock setting, and the interrupt vector parameter is provided with, and the universal I/O port parameter is provided with, and EVA task manager parameter is provided with.Carry out angular displacement sensor then line parameter is set, setting and visiting fork value of angular displacement sensor when the corn stubble interline is deg, and sets this value for judging whether sensor is in the fiducial value to the row state.Read the output digital quantity angle of angular displacement sensor then, angle value and deg value are compared judgement, if two-value equates then to be judged to be to the row state, electromagnetic proportional valve is put the meta off-load, and the facility lead is constant; If the angle value is greater than the deg value, then electromagnetic proportional valve 22 is put right position, the facility lead is adjusted, otherwise electromagnetic proportional valve 22 is put position, a left side, revises the lead of facility.
Figure 4 shows that the oil circuit control schematic diagram of this device, in fact also is the description to hydraulic valve 7.The hydraulic oil of being exported by oil pump by fuel tank flow to hydraulic cylinder through electromagnetic proportional valve, and electromagnetic proportional valve is used to control the direction and the flow of fluid.When electromagnetic proportional valve was put position, a left side, the piston rod of hydraulic cylinder A moved to right, and the piston rod of hydraulic cylinder B moves to left, thereby driving leading truck 14 rotates around axle 11, revises the facility direction of advance.In like manner, when electromagnetic proportional valve was put right, fluid was oppositely supplied with, and the piston rod of hydraulic cylinder A moves to left, and the piston rod of hydraulic cylinder B moves to right, and revises the lead of facility.When electromagnetic proportional valve is put meta, adopt electromagnetic relief valve 24 to carry out off-load.The facility lead is constant.For preventing that fluid from oppositely flowing backwards, used check valve in the hydraulic circuit.
Be illustrated in figure 5 as the workflow of this device, at first by visiting fork 19 induction angular deflections, measure its deviation angle value by angular displacement sensor 20 then, this signal is transferred to control module 4, carry out computational analysis by 4 pairs of these signals of control module, compare judgement with setting value then, and make instruction control hydraulic valve 7, and then the force direction of control hydraulic cylinder 3, the lead of change leading truck 14.
During operation, visiting fork passes between Liang Long, when facility departed from, visiting fork will deflect under the active force of corn stubble, and remains consistent with the bearing of trend on ridge, visiting fork surveys by angular displacement sensor with the deflection angle of facility, be transferred to the big or small angle that control module calculates deflection angle by signal input line, and compare, if two-value equates then to be judged to be to the row state with setting value deg, electromagnetic proportional valve is put the meta off-load, and the facility lead is constant; If the angle value is greater than the deg value, then electromagnetic proportional valve is put right position, the facility lead is adjusted, otherwise electromagnetic proportional valve is put position, a left side, revises the lead of facility.Facts have proved, the offset direction of the differentiation facility that this system can be correct, and provide correct instruction, and revise the direction of advance of facility, guarantee facility operation on the ridge.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
