Description
Technical field
The present invention relates to a kind of tractor lifting mechanism and handle the linkage of exporting with power, belong to wheel tractor technical field.
Background technology
Farm machinery for do mechanization operation, normally a hitch is arranged on to the rear portion of tractor, hydraulic means is controlled the action of hitch, makes the job position state of farm machinery in lifting or various different tilling depth, and 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 associated with its power, in routine operation, operating personnel are first operated clutch electric-controlled switch knobs, break-make by 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, after farm machinery are promoted, leaving farmland 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 lifter control crank on manipulation lifter, because farm machinery can work under tractor dynamic power drives, therefore entail dangers to, 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 object of the present invention provides, and when handling lifter control crank, can control power output, improves the linkage of tractor lifting mechanism manipulation with the power output of operational security.
The present invention is that the technical scheme achieving the above object is: a kind of tractor lifting mechanism is handled the linkage with power output, comprise the lifter manipulation holder that lifter control crank is installed, hydraulic clutch and the power output assembly being 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, clutch electric-controlled switch is arranged on the adjustable plate of the position of the switch, on clutch electric-controlled switch, be hinged with pressing plate, 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 and pressing plate outer end in lifter control crank periphery join, clutch electric-controlled switch and control valve electrical connection.
The present invention handles on holder position of the switch adjustable plate is installed at lifter, clutch electric-controlled switch is arranged on the adjustable plate of the position of the switch, by the pressing plate solenoidoperated cluthes electric-controlled switch upper contact head that is hinged on the pressing plate on clutch electric-controlled switch or be hinged on the adjustable plate of the position of the switch, move, because the cam surface in pressing plate one side and lifter control crank periphery joins, therefore operating personnel is when handling lifter lifting farm machinery, because rotating, lifter control crank depresses pressing plate by its cam surface, make pressing plate control contact action, by the break-make of clutch electric-controlled switch, make control valve action and whether control hydraulic oil to 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 present invention is simple in structure, can automatically cut off power output when promoting farm machinery, while effectively reducing work, injures unexpectedly, and has improved job safety raising.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
Fig. 1 is the structural representation that tractor lifting mechanism of the present invention is handled the linkage of exporting with power.
Fig. 2 is the structural representation that lifter of the present invention is handled holder.
Wherein: 1-lifter control crank, 1-1-cam surface, 2-roller, 3-pressing plate, 4-lifter is handled holder, 5-clutch electric-controlled switch, 5-1-contact, 6-switch fixing casing, 7-position of the switch adjustable plate, 8-control valve, 9-hydraulic clutch, 10-power output assembly.
Embodiment
See Fig. 1, shown in 2, tractor lifting mechanism of the present invention is handled the linkage with power output, comprise the lifter manipulation holder 4 that lifter control crank 1 is installed, hydraulic clutch 9 and the power output assembly 10 being connected with hydraulic clutch 9, the oil circuit of hydraulic clutch 9 is connected with control valve 8, oil pocket on hydraulic clutch 9 is connected with control valve 8 by oil pipe, hydraulic clutch 9 of the present invention and control valve 8 are commercially available prod, by control valve 8, whether control hydraulic oil to hydraulic clutch 9 fuel feeding, by hydraulic oil, make main, driven friction in conjunction with and outputting power, or the master of hydraulic clutch 9, driven friction is separated, make hydraulic clutch 9 cut off power in released state.The present invention adopts conventional power output assembly 10, as shown in Figure 1, the exportable different rotating speeds of this power output assembly 10 is to meet job requirements, this power output assembly 10 adopts gear transmission structure, two groups of gears are installed on its power shaft, two groups of gears with its engagement are installed on output shaft, by being arranged on slip cap on output shaft, realize the speed of different work and export.
See Fig. 1, shown in 2, lifter of the present invention is handled on holder 4 position of the switch adjustable plate 7 is installed, this lifter is handled holder 4 and is arranged in frame, clutch electric-controlled switch 5 is arranged on position of the switch adjustable plate 7, on clutch electric-controlled switch 5, be hinged with pressing plate 3, or on position of the switch adjustable plate 7, be hinged with pressing plate 3, make the pressing plate 3 can be along its hinged center rotating, and pressing plate 3 joins and controls contact 5-1 action with the contact 5-1 on clutch electric-controlled switch 5, lifter control crank 1 is arranged on lifter and handles holder 4, the lifting that realizes farm machinery by rotation lifter control crank 1 is handled, cam surface 1-1 in lifter control crank 1 periphery and pressing plate 3 outer ends join, clutch electric-controlled switch 5 and control valve 8 electrical connections, when operation lifter control crank 1, lifter control crank 1 is rotated, by cam surface 1-1, depress contact 5-1 solenoidoperated cluthes electric-controlled switch 5 break-makes and realize 8 actions of control control valve.
See that, shown in Fig. 1,2, the present invention installs clutch electric-controlled switch 5 for convenience, switch fixing casing 6 is installed on position of the switch adjustable plate 7, clutch electric-controlled switch 5 is arranged on switch fixing casing 6, and now one end of pressing plate 3 is hinged on switch fixing casing 6.The present invention is for making lifter control crank 1 can control reliably pressing plate 3, the outer end of pressing plate 3 is provided with support, roller 2 is rack-mount, this roller adopts bearing, cam surface 1-1 and roller 2 in lifter control crank 1 periphery join, cam surface 1-1 in lifter control crank 1 periphery of the present invention is plane or curved surface, sees shown in Fig. 1,2, changes its diameter depress pressing plate 3 by the plane in lifter control crank 1 periphery when rotating.
