Preferred: described in the bar that contacts to earth from top to bottom be integrally connected formed by upper arm, inclination linking arm and the level arm that contacts to earth.
Preferred: the described first tactile combination switch and second touches combination switch axial symmetry and is arranged on cutting height by-pass cock arm.Setting like this, controls more accurate.
Preferred: described power supply is accumulator.
The present invention compared with prior art has following effect:
Harvester header automatic lifting system of the present invention contacts to earth bar and earth surface or leave ground, and combination switch is touched in the bar upper arm that contacts to earth touching, and touch combination switch by power line connecting fluid pressure electromagnetic valve, described hydraulic buttery valve connects taiwan cut off and landing oil cylinder by fluid pressure line.Under any condition, the cutter of grain header can keep contour with ground, makes to cut stubble and is consistent, can also preset cutting height, improves results quality, alleviates driver's labour intensity.
Accompanying drawing explanation
Fig. 1 is the structure chart of harvester header automatic lifting system;
Fig. 2 is the A place enlarged drawing of Fig. 1.
Embodiment
Elaborate the preferred embodiment of the present invention with reference to the accompanying drawings below.
Embodiment: the harvester header automatic lifting system of present embodiment comprises push-rod electric machine 2, the bar 3 that contacts to earth, cutting height by-pass cock arm 5, first touch combination switch 6, second and touch combination switch 7, hydraulic buttery valve 8, cut batch gauge tap 9, power supply 11 and taiwan cut off and landing oil cylinder 19, described push-rod electric machine 2 is arranged in the ceding of Taiwan 1, the push rod of push-rod electric machine 2 is connected with the upper end of cutting height by-pass cock arm 5, first tactile combination switch 6 and the second tactile combination switch 7 are arranged on cutting height by-pass cock arm 5, the upper arm 4 of bar 3 of contacting to earth is inserted by the lower end of cutting height by-pass cock arm 5, and the upper extreme point height of the bar 3 that contacts to earth touches the setting height(from bottom) of combination switch 6 and the second tactile combination switch 7 higher than first, described push-rod electric machine 2 by power line with cut batch gauge tap 9 and be connected, taiwan cut off and landing oil cylinder 19 is arranged on grain header, the pull bar of taiwan cut off and landing oil cylinder 19 is connected with the ceding of Taiwan 1, taiwan cut off and landing oil cylinder 19 is connected with hydraulic buttery valve 8 by fluid pressure line, hydraulic buttery valve 8 touches combination switch 6 respectively with first by power line and the second tactile combination switch 7 is connected, power supply 11 is for cutting batch gauge tap 9, first tactile combination switch 6 and the second tactile combination switch 7 are powered.
Further: described in the bar 3 that contacts to earth from top to bottom be integrally connected formed by upper arm 4, inclination linking arm 10 and the level arm 12 that contacts to earth.
Further: the described first tactile combination switch 6 and the second tactile combination switch 7 axial symmetry are arranged on cutting height by-pass cock arm 5.Setting like this, controls more accurate.
Further: described power supply 11 is accumulator.
Harvester header automatic lifting system of the present invention pulls and promotes to regulate by push-rod electric machine 2 height of bar 3 and cutter of contacting to earth, thus realizes the electrodeless adjustment of cutting height, and push-rod electric machine 2 is controlled by power line by cutting batch gauge tap 9.When contact to earth bar 3 kiss the earth time the contact to earth upper arm 4 of bar press to tactile combination switch 6, touch combination switch 6 closed by power line connecting fluid pressure electromagnetic valve 8, hydraulic buttery valve 8 makes the ceding of Taiwan 1 promote by fluid pressure line to taiwan cut off and landing oil cylinder 19 fuel feeding, otherwise the upper arm 4 of the bar that contacts to earth when the bar 3 that contacts to earth leaves ground presses to tactile combination switch 7, touch combination switch 7 closed by power line connecting fluid pressure electromagnetic valve 8, hydraulic buttery valve 8 makes the ceding of Taiwan 1 decline by fluid pressure line to taiwan cut off and landing oil cylinder 19 draining, when contact to earth bar 3 just kiss the earth time the contact to earth upper arm 4 of bar do not touch tactile combination switch 6 and tactile combination switch 7, the ceding of Taiwan 1 is remained neutral.Power supply 11 is multiple power sources (accumulator) of grain header, is connected cut batch gauge tap 9 by power line.
