Middle drive shaft sprocket 15 is mounted on intermediate propeller shaft, and engine rotation drives the rotation of intermediate propeller shaft to make drive shaft sprocket 15
It starts turning, meanwhile, drive shaft sprocket 15 drives chain to be moved, and drives feeding screw feeder sprocket wheel 19 to rotate, while driving and stirring
Imperial cylinder rotates, and has minor sprocket 18 on screw feeder cylinder, drives the big sprocket wheel 16 of top to rotate by chain conveyer, while small synchronous pulley 17
Setting in motion drives the big synchronous pulley 20 installed in front of side wall to rotate, so that winder be driven to carry out by toothed belt transmission
Rotation.
In conjunction with shown in Fig. 1,2, synchronous pulley of the present invention is mounted on an axle, and is transmitted torque with key connection and realized axial direction
Fixed, small synchronous pulley is mounted on the last square shaft of the ceding of Taiwan, and big synchronous pulley links together with rice crop-poking wheel axis, synchronous belt tensioning
Wheel is mounted on pivoted arm 44, and pivoted arm is connected further through bolt with tensioner arm, meanwhile, tensioner arm end is connected with a spring
Hanging plate 45 is connected on reel support with spring 46, realizes auto-tensioning adjustment effect.
In conjunction with shown in Fig. 3,5, winder of the present invention is located above the ceding of Taiwan, including dials standing grain elastic claw, rice-pulling shaft and make its bias
The crank and eccentric adjusting disk of movement, winder both ends are supported with bracket, and winder uses V belt translation, are connected with nothing on the right side of rear end
Grade change pulley 14 adjusts the revolving speed of winder, and stepless change wheel 14 includes that hand handle 1 is embedded in gland 2, turn hand handle 1 for band
Dynamic pressure lid is to drive Moving plate 3 to rotate, to adjust the gap between Moving plate 3 and price fixing 4, to control the contact area of band, thus
The speed of V belt translation is controlled, there is nut on stepless change wheel head, and to stepless change wheel axial restraint, stepless change wheel passes through band
Transmission is directly connect with main transmission, by controlling the revolving speed of connecting shaft, so that left side synchronous pulley revolving speed is controlled, to adjust
Winder revolving speed.Meanwhile stepless change wheel can be by adjusting the width between driving wheel and fixed wheel, to control the effect of V belt translation
Rate, to control the revolving speed of winder.The cylinder body of reel lift oil cylinder is bolted on the rear hydraulic branch of side wall simultaneously
On fagging, push rod is bolted on reel support.
The cut portion is located at ceding of Taiwan bottom, including ledger-plate, cutting blade, guard, knife pressing device, short grass guide board, length
Grass guide board etc. is driven cutting blade bilateral reciprocation, has been cooperated with ledger-plate by rocking bar combination 38 and intermediate transmission axis connection
At harvesting.
As shown in connection with fig. 4, there is one piece of stiffening plate on sidewall paneling 25 below right side wall upper beam 22, for increasing side wall upper beam
Intensity may be coupled to the upper end of side wall front-axle beam on reel support, and side wall front-axle beam lower end is one piece of connecting plate, is used to and divides
Standing grain device is attached；There are two tension pulley supports 21 on the sidewall paneling left side, have sliding slot thereon, tensioning wheel can slide in sliding slot to be come
Position is adjusted, the tensioning to sprocket wheel is met with this；Side wall stiffening plate 26 is mounted on sidewall paneling 25, increases the strong of sidewall paneling

In conclusion the grain harvesting machine ceding of Taiwan of the invention, is on the one hand adjusted the position of transmission device, it will be same
Step belt wheel 17 is directly attached with big sprocket wheel 16, and transmission is got up right side more convenient, and that stepless change wheel 14 is placed on to the ceding of Taiwan
Side is directly connect with main transmission, controls winder speed, while controlling the speed of header transmission system, meanwhile, tensioning wheel
35 are mounted in tensioning wheel supporting block 21, can carry out the adjusting of tensioning wheel position at any time, and synchronous belt tensioner pulley 43 is connected with spring
It connects on reel support, equally can produce a pre-tensioned power.And its is compact-sized, when problem occurs for transmission device
When, it is only necessary to a side protective plate is dismantled, so that it may it tests and repairs, it is more convenient to use.
On the other hand, using toothed belt transmission, band does not produce relative sliding directly with belt wheel, can guarantee accurate transmission
Than, while tool has good wearability and transmission stability again, and does not need oil lubrication, the service life of synchronous belt is also than the band that rubs
Long, the wear problem of the vibration of conveyer belt and band when can effectively reduce field work, the service life of elongated strap reduces maintenance frequency.
