Description
Technical field
The utility model relates to a kind of tractor lifting mechanism and handles the linkage of exporting with power, belongs to the wheel tractor technical field.
Background technology
Farm machinery for do mechanization operation, normally a hitch is arranged on the rear portion of tractor, hydraulic means is controlled the action of hitch, makes farm machinery be in the job position state of lifting or various different tilling depth, and the tractor outputting power offers farm machinery to complete various operations.
Wheel tractor is rear-mounted farm machinery, because the lifter of hitch is exported without any related with its power, in routine operation, operating personnel are first operated clutch electric-controlled switch knobs, break-make by the clutch electric-controlled switch makes control valve control the oil circuit of hydraulic clutch, make the normal power output of hydraulic clutch or cut off power output, and then handling the lifter control crank on lifter, leaving the farmland after farm machinery are promoted and just can carry out conventional travelling.But in practical operation, due to operating personnel's operate miss, when not controlling the output of hydraulic clutch cut-out power, and the lifter control crank on the manipulation lifter, because farm machinery can work under tractor dynamic power drives, therefore entail dangers to operating personnel and related personnel's safety, has reduced the processing safety of tractor.
Summary of the invention
It is a kind of simple and reasonable for structure that the purpose of this utility model provides, and can control power output when handling the lifter control crank, improves the linkage of tractor lifting mechanism manipulation with the power output of operational security.
the utility model is that the technical scheme that achieves the above object is: a kind of tractor lifting mechanism is handled the linkage with power output, comprise the lifter manipulation holder that the lifter control crank is installed, hydraulic clutch and the power output assembly that is connected with hydraulic clutch, the oil circuit of hydraulic clutch is connected with control valve, it is characterized in that: described lifter is handled on holder position of the switch adjustable plate is installed, the clutch electric-controlled switch is arranged on the adjustable plate of the position of the switch, be hinged with pressing plate on the clutch electric-controlled switch, or be hinged with pressing plate on the adjustable plate of the position of the switch, and the contact on pressing plate and clutch electric-controlled switch joins and controls contact action, cam surface on lifter control crank periphery and pressing plate outer end join, clutch electric-controlled switch and control valve electrical connection.
the utility model is handled on holder at lifter position of the switch adjustable plate is installed, the clutch electric-controlled switch is arranged on the adjustable plate of the position of the switch, move by the pressing plate solenoidoperated cluthes electric-controlled switch upper contact head that is hinged on the pressing plate on the clutch electric-controlled switch or be hinged on the adjustable plate of the position of the switch, because the cam surface on pressing plate one side and lifter control crank periphery joins, therefore the operating personnel is when handling lifter lifting farm machinery, because rotating, the lifter control crank depresses pressing plate by its cam surface, make pressing plate control contact action, break-make by the clutch electric-controlled switch, make the control valve action and whether control hydraulic oil to the hydraulic pressure clutch feed, control the normal power output of hydraulic clutch or cut off power output, guarantee that farm machinery can be not in running order after lifting.The utility model is simple in structure, can automatically cut off power output when promoting farm machinery, injures unexpectedly when effectively reducing work, has improved the job safety raising.
