Abstract
The utility model discloses a sliding type belt pulley transmission mechanism in header parts of a lawn mower. The engine of the belt pulley transmission mechanism is fixed on a rack, a header is connected to the rack and can move up and down relatively to the rack, a bracket is fixed on the header, and a header transmission belt is fixedly sleeved on the output shaft of the engine; an external spline shaft is also fixed on the output shaft of the engine, an internal spline belt pulley is installed on the external spline shaft, the header transmission belt is installed on the internal spline belt pulley, the lower end of the internal spline belt pulley is connected with a shock-absorbing sleeve, a bearing and a bearing seat base plate, and the bearing seat base plate is connected to the bracket. The belt pulley on the engine can slide up and down on the output shaft of the engine along with the raising height of the header through the spline mechanism, therefore, the header transmission belt is in one plane and is driven in one plane, and the service life of the belt is prolonged.
Description
Technical field
The utility model relates to a kind of hay mower, relates in particular to the pulley transmission mechanism in the hay mower ceding of Taiwan parts.
Background technology
The hay mower of floating header is by adjusting the height of the ceding of Taiwan with respect to frame, realizing the adjustment highly of mowing, and is one of the most frequently used mechanism of hay mower.Its structure is: engine is fixed on the frame, by being fixed on belt pulley, the belt pulley transferring power of ceding of Taiwan driving belt in the ceding of Taiwan on the engine, because the ceding of Taiwan can be adjusted variation with respect to the height of frame, so the belt pulley that is fixed in the ceding of Taiwan changes with respect to the height that is fixed on the belt pulley on the engine, often tilt so connect the driving belt of two belt pulleys.And the belt that tilts can make the wearing and tearing of belt strengthen, and belt life shortens greatly.
For solving above technical problem, the lawn machine that has is at present heightened the angle of inclination that scope reduces belt, life-span of improving belt by reducing the ceding of Taiwan.But the applicability of complete machine can reduce along with the scope of the height of mowing and reduce.The lawn machine that also has designs two belt pulleys under engine, the ceding of Taiwan height that top belt pulley is corresponding higher, and the ceding of Taiwan height that following belt pulley correspondence is lower reduces the purpose that belt tilts thereby reach.But the hay mower complicated operation of this mechanism and forget operation easily changes belt pulley in case the user forgets, it is bigger that belt is tilted, and belt life is shorter.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, the slidingtype pulley transmission mechanism in a kind of hay mower ceding of Taiwan parts is provided, having solved fixed belt pulley and heightened the problem that causes belt to tilt because of the ceding of Taiwan.
The technical solution adopted in the utility model is: the engine of pulley transmission mechanism is fixed on the frame, and the ceding of Taiwan is connected on the frame and can moves up and down with respect to frame, and carriage is fixed in the ceding of Taiwan, overlaps ceding of Taiwan driving belt on the output shaft of engine admittedly; Fixing male splined shaft also on the output shaft of engine, the internal spline belt pulley is installed on the male splined shaft, ceding of Taiwan driving belt is installed on the internal spline belt pulley, and the lower end of internal spline belt pulley and shock-absorbing sleeve, bearing and pedestal base link together, and pedestal base is connected on the carriage.
The utility model can slide up and down the belt pulley on the engine along with heightening of the ceding of Taiwan by spline mechanism on engine output shaft, thereby ceding of Taiwan driving belt is remained in the plane, the transmission in same plane of ceding of Taiwan power belt has prolonged belt life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a main cutaway view of the present utility model;
Fig. 2 is that partial sectional view is looked on the right side of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1 engine, 2. flap bar, 3. male splined shaft, 4. ceding of Taiwan driving belt, 5. internal spline belt pulley, 6. pedestal base, 7. bearing, 8. carriage, the 9. ceding of Taiwan, 10. shock-absorbing sleeve, 11. spacer pins.
Embodiment
Shown in Fig. 1～3, the engine 1 of the pulley transmission mechanism in the hay mower ceding of Taiwan parts is fixed on the frame, and the ceding of Taiwan 9 is connected on the frame and can moves up and down with respect to frame.Admittedly overlap ceding of Taiwan driving belt 4 on the output shaft of engine 1, also overlap male splined shaft 3 on the output shaft of engine 1, male splined shaft 3 is fastened on the engine 1.Internal spline belt pulley 5 is installed on the male splined shaft 3, and internal spline belt pulley 5 is enclosed within on the male splined shaft 3 and can slides up and down.Ceding of Taiwan driving belt 4 is installed on the internal spline belt pulley 5.Shock-absorbing sleeve 10, internal spline belt pulley 5, bearing 7 and pedestal base 6 link together.Internal spline belt pulley 5 is connected with the inner ring of bearing 7, and pedestal base 6 is connected with the outer ring of bearing 7.Shock-absorbing sleeve 10 is fixed in two holes at pedestal base 6 two ends.Pedestal base 6 is connected on the carriage 8 by the bottom of two flap bars 2, and carriage 8 is connected in the ceding of Taiwan 9, and flap bar 2 passes to be installed spacer pin 11 behind two holes at pedestal base 6 two ends at an upper portion thereof and block and prevent to come off.So just form an integral body, when the ceding of Taiwan 9 is heightened, drive internal spline belt pulley 5 and slide up and down along male splined shaft 3 by carriage 8, pedestal base 6.And the power of engine 1 also can be delivered in the ceding of Taiwan 9 by spline pair and ceding of Taiwan driving belt.
