Description
Technical field
The present invention relates to a kind of gearbox of agricultural machinery, especially a kind of gearbox that is used for multiple field management function.
Background technique
The common function of existing miniature farm machinery is comparatively single, except the output of walking power, only is furnished with an output shaft usually in addition; Rotary cultivator for example commonly used; And this output shaft links to each other with the walking pto, and the speed of output shaft receives the restriction of walking power output, can't realize more function.Though existing gearbox technology is comparatively flourishing, considers that its Environmental Conditions of agricultural machinery that is used for field management is comparatively abominable, and the user is comparatively responsive for price usually, and therefore in function, there is bigger technical difficulty in seeking balance between performance and the price.
Summary of the invention
Technical problem to be solved by this invention provides multi-functional garden supervisor, has many independent power output routes, can realize more field management function.
For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: a kind of gearbox that is used for multi-functional garden supervisor; Gearbox is provided with and is used for the input shaft that is connected with drive unit; Also be provided with and be used for the output shaft that is connected with road wheel, gearbox also is provided with first output shaft and second output shaft that is used to connect farm implements, and first output shaft and second output shaft lay respectively at the both sides, front and back of road wheel.
One side of gearbox also is provided with the operating console of stirring shifting slide gear in the gearbox or slippage spline housing with a plurality of shift forks.
Described gearbox is respectively equipped with three drive paths, is respectively traction drive route, the first output shaft drive path and the second output shaft drive path.
It is characterized in that: also be provided with in the described gearbox and reverse gear,, realize reversing gear with the 11 first gear and input shaft second gear meshing through the tenth first gear and input shaft the 3rd gear of slip on it.
Also be provided with the input shaft output disc that is used to connect generator, suction engine or air compressor on the described input shaft.
In the described traction drive route; Power is transferred to road wheel through input shaft, second, the 3rd, the 4th and the 5th; Each is provided with gear, shifting slide gear and/or slippage spline housing, and stirs through the shift fork of operating console, realizes that two fast neutrals, six speed walking retainings and two speed reverse gear.
The described first output shaft drive path is input shaft, the 6th, the 7th, the 9th, the 8th, and gives cardan shaft through the bevel gear set transmission, and first output shaft is given in the cardan shaft transmission;
Each is provided with gear and/or shifting slide gear, through the operating console shift fork, and cooperates the gear on the tenth, realizes each two speed work retaining of clockwise and anticlockwise.
The described second output shaft drive path is input shaft, second, the 3rd, the 11, and gives cardan shaft through the bevel gear set transmission, and second output shaft is given in the cardan shaft transmission;
Each is provided with gear, shifting slide gear and/or slippage spline housing, stirs through the shift fork of operating console, and cooperates the gear on the tenth, realizes each two speed work retaining of clockwise and anticlockwise.
