Description
Affiliated technical field
The utility model relates to a kind of and the matching used rotovator gearbox of wheel tractor, and particularly a kind of energy realizes just changeing the rotovator gearbox of rotary tillage, counter-rotating stubble-cleaning function for one the case.
Background technology
Along with wideling popularize with the innovation of farm machinery of agricultural mechanization production regenerated, the farm machinery of function singleness have not satisfied existing agriculture requirement and agricultural production demand.Traditional and the matching used rotovator gearbox of wheel tractor, the power outbound course is single, promptly can only just change maybe and can only reverse, and must change device or parts and could realize rotary tillage operation or stubble-cleaning operation on a machine.Our technical staff finds that when investigation general operative employee can not reach correct assembling requirement, thereby influence the transaction capabilities and the service life of facility when dismounting and assemble products from parts.The operation function that facility are single and loaded down with trivial details charge and discharge operations have also influenced the enthusiasm that the vast farmers friend purchases machine.
Summary of the invention
It is matching used with wheel tractor that the purpose of this utility model is to provide, diverse in function, and can avoid in the use a kind of rotovator gearbox of loading and unloading parts troublesome operation with rotating function.
Technical solution of the present utility model is: a kind of rotovator with rotating function comprises casing with gearbox, be erected at power shaft, transition axis, power transmission shaft on the casing, stir device, and be arranged on bevel gear wheel, bevel pinion and two duplicate gears on the axle; Power shaft one end and tractor propeller shaft couplings, the other end is provided with duplicate gear I, duplicate gear II is located on the transition axis, the bevel gear wheel of being located on the power transmission shaft often meshes with the bevel pinion of being located on the transition axis, it is characterized in that: the utility model also comprises a stub that is erected on the casing, stub is provided with mesomerism gear, the front end of stirring device is plugged in the annular groove of duplicate gear I or II, plug the duplicate gear of stirring device and can do moving of adjacent two positions vertically, position two duplicate gears directly mesh therein, and the mesomerism gear transmission of passing through of another location two duplicate gears is meshed.
Not only can realize just changeing rotary tillage, two kinds of functions of counter-rotating stubble-cleaning by a machine in order to make gearbox, can also in rotary tillage or stubble-cleaning, export drilling power, the utility model also comprises a worm-wheel shaft that is set up on the casing, establishes worm screw on the stub, and worm screw often meshes with the worm gear of being located on the worm-wheel shaft.The power output of worm-wheel shaft is used for drilling.
The utility model owing to set up a stub in gearbox, and is direct engagements by stirring two duplicate gears of device control, and still by mesomerism gear transmission engagement, so the power of gearbox output has positive and negative two adjustable turning to and rotating speed.Because stub is provided with worm and worm gear, worm-wheel shaft produces an outputting power again, and therefore, gearbox can also provide power for drilling when providing power for rotary tillage, stubble-cleaning.The utility model changes the present situation of existing farm machinery function singleness, has avoided a series of troublesome operation of loading and unloading parts in the use, and one case many usefulness is purchased the machine cost for the peasant has saved.
