Embodiment
As shown in Figure 1, the combine man is made up of manual change-over switch 1, handle 2, clamp nut 3, movable stand 4, pull bar 5, driver, piston rod 7, bolt assembly (constituting 11 by bolt 8, friction plate 9, pad 10, nut), anchorage bar 12, driving pendulum rod 13, connecting rod 14, limit switch 17, bearing 16 from integrated speed governing actuating unit.
Manual change-over switch 1 mainly is made up of press button and status indicator lamp, and when not pressing the button, status indicator lamp does not work, and combined harvester is in manual operation state; When pressing the button, status indicator lamp shows, shows that combined harvester is in automatic mode of operation.Automatically control section mainly is made up of driver, piston rod 7, limit switch 17; When the combined harvester pace is in automatic control state; Stretching out and retraction of driver drives piston rod 7; Move forward and backward thereby drive combined harvester, in this process, judge through former and later two limit switches of handle whether handle arrives the extreme position of operation.
As shown in Figure 1; The combine man forms from manual governing clamp mechanism and automatic speed regulation clamp mechanism that one hydraulic stepless speed regulating executing agency is based on hydraulic continuously variable transmission, and the manual governing clamp mechanism comprises manual switch 1, handle 2, clamp nut 3, movable stand 4, pull bar 5, bolt 8, friction plate 9, pad 10, nut 11, anchorage bar 12; The automatic speed regulation clamp mechanism comprises driver 6, piston rod 7, driving pendulum rod 13, connecting rod 14 and limit switch 17.Automatic/hand switch 1 is installed on the handle 2; Handle 2 is hinged with movable stand 4, and movable stand 4 is connected with bearing 16 through bolt 8, friction plate 9, pad 10, nut 11, and pull bar 5 is connected with driving pendulum rod 13 1 ends with movable stand 4 respectively and connects; Driving pendulum rod 13 other ends are connected with connecting rod 14; Driving pendulum rod 13 is hinged on the anchorage bar 12, and anchorage bar 12 is welded on the bearing 16, and an end and the handle 2 of piston rod 7 weld together simultaneously; The other end is connected with driver 6, and driver 6 is fixed on the bearing 16.
As shown in Figure 2, bearing 16 is installed on the combined harvester, and handle 2 passes the slotted eye on the bearing 16, and can in the hole, move forward and backward,, limit switch 17 is installed in the extreme position A161 and the extreme position B162 place of bearing 16.
When the tractor driver operates the combining machine operation; Through pulling handle 2; Movable stand 4 is rotated around the hinged center of itself and bearing; Through pull bar 5 pulling driving pendulum rod 13 around axis swing, thereby drive the executing agency 15 of combined harvesters through connecting rod 14, realize the manual adjustment of combined harvester pace.
When combined harvester is in automatic control state; Thereby stretching motion through control driver 6 piston rod 7; And then reaching moving forward and backward of joystick 2, the motion of handle 2 drives movable stand 4 and rotates around its hinged center with bearing, spurs driving pendulum rod 13 around axis swing through pull bar 5; Thereby the executing agency 15 through connecting rod 14 drive combined harvesters realizes the automatic control of combined harvester pace.
The tractor driver through press the manual change-over switch 1 on fixed handle 2 tops, is switched on or switched off the power supply of driver 6 in handling the combined harvester operation process, and make the work of automatic speed regulation clamp mechanism or stop, thus the switching of realization manual state and auto state.
