Abstract
The utility model discloses a gearbox steering device of a micro-cultivator. The gearbox steering device of the micro-cultivator comprises a power output mechanism and a steering mechanism, the power output mechanism is composed of a first output bevel gear and a second output bevel gear which are connected through an output connecting shaft, the steering mechanism is composed of an output spline shaft, a third output bevel gear, hexagonal axles and spline slide bushes, the third output bevel gear is arranged at the middle of the output spline shaft and engaged to the gear of the second output bevel gear, each of two ends of the output spline shaft is connected with the hexagonal axle, each joint is provided with the spline slide bush, each spline slide bush is provided with a transmission fork, each transmission fork is provided with a steering pull rod, the end of each hexagonal axle connected with the output spline shaft is provided with a spline, a spring sleeve is arranged at the middle of each hexagonal axle, and a reset spring is arranged between each spline bush and the corresponding spring sleeve. According to the gearbox steering device of the micro-cultivator, the steering pull rods pull the transmission forks to drive the spline slide bushes to slide between the output spline shaft and the spline ends of the hexagonal axles so as to realize the purpose that one side wheel has power output while the other side wheel does not have power output, and then the steering function is achieved.
Description
Technical field
The utility model belongs to agricultural machinery technological field, especially a kind of gear box of micro-cultivator the steering gear.
Background technique
The gear box of micro-cultivator using is at present all general old-fashioned gearbox, the output spline two ends of this gearbox are fixedly connected with wheel six square shafts, there is no the steering gear, due to this Gearbox design defect, when microtilling machine is turned under steam, need user of service to enforce operation handlebar twisting upper saw pulley, could realize microtilling machine and turn to, this gearbox is deposited firmly large in use, turns to the defects such as difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of gear box of micro-cultivator the steering gear.
The technical solution adopted in the utility model: a kind of gear box of micro-cultivator the steering gear, comprise power take-off mechanism and steering equipment, by exporting, coupling shaft connects output umbrella tooth one to described power take-off mechanism and output umbrella tooth two forms, described steering equipment is by output spline, output umbrella tooth three, take turns six square shafts, spline sleeve composition, output umbrella tooth three is installed in the middle of described output spline, output umbrella tooth three and the engaged gears of exporting umbrella tooth two, described output spline two ends connecting wheel six square shafts, joint arranges spline sleeve, above described spline sleeve, be provided with shift fork, above shift fork, be provided with steering linkages, described wheel six square shafts be provided with spline with output spline connecting end, the described middle spring housing that arranges of six square shafts of taking turns, between spline sleeve and spring housing, Returnning spring is installed.
When the utility model uses, pull shift fork to stir spline sleeve slide in the splined end of output spline and wheel six square shafts, can easily achieve the dynamic output of a side wheel by steering linkages, another side wheel does not have power output, thereby realizes turning function.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Fig. 1 is the utility model structural representation.
In Fig. 1: 1 output umbrella tooth one, 2 output coupling shaft, 3 output umbrella tooth two, 4 steering linkagess, 5 Returnning springs, 6 shift forks, 7 output splines, 8 output umbrella tooth three, 9 spline sleeves, 10 spring housings, 11 take turns six square shafts.
Embodiment
A kind of gear box of micro-cultivator the steering gear as shown in the figure, comprise power take-off mechanism and steering equipment, by exporting, coupling shaft 2 connects output umbrella tooth 1 to described power take-off mechanism and output umbrella tooth 22 forms, described steering equipment is by output spline 7, output umbrella tooth 38, take turns six square shafts 11, spline sleeve 9 forms, output umbrella tooth 38 is installed in the middle of output spline 7, output umbrella tooth 38 and the engaged gears of exporting umbrella tooth 23, described output spline 7 two ends connecting wheel six square shafts 11, joint arranges spline sleeve 9, described spline sleeve 9 is provided with shift fork 6 above, shift fork 6 is provided with steering linkages 4 above, that takes turns six square shafts 11 is provided with spline with output spline 7 connecting ends, in the middle of taking turns six square shafts 11, spring housing 10 is set, between spline sleeve 9 and spring housing 10, Returnning spring 5 is installed.
When use, pull shift fork 6 to stir spline sleeve 9 slide in the splined end of output spline 7 and wheel six square shafts 11, can easily achieve the dynamic output of a side wheel by steering linkages 4, another side wheel does not have power output, thereby realizes turning function.
