Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a combine threshing apparatus 1 and a structure around it. The threshing apparatus 1 in this combine handles the spikes with a handle drum 4 that is driven and rotated in a handling chamber 7 while clamping the stem side of the grain stalk by a feed chain 2 and a holding rail 3, thereby forming a circular arc. The treated material that has leaked from the receiving net 56 is subjected to grain and
Sorted into the second product, waste straw waste, etc., the grain is carried out to the outer grain recovery device on the lateral side by the first material collection screw 6, and the second product is stored in the handling room 7 by the second product collection screw 52. And reprocess,
The fine waste dust is discharged outside the machine by a dust blower 8. Further, on the lower side of the threshing device 1, an upper chain type stock feeder mechanism 9 for pinching and feeding the stocker side of the discharge straw, and a spike feeder mechanism 10 for locking and conveying the spike side from above. A transfer device 11 is provided to receive the waste straw sent from the feed chain 2,
It is configured to be transported and supplied to a position above a waste straw cutter (not shown).

As shown in FIG. 2 and FIG. 3, a first transmission shaft 12 for driving the handle drum driven by the prime mover is disposed on the opposite side of the handle 13 and in parallel with the handle cylinder axis P. The first transmission shaft 12 is connected to the input pulley 14 on the upper side of the handling shaft in the grain conveying direction via the belt transmission mechanism 32, and the first transmission shaft 12 is extended to the lower side in the grain conveying direction, and the extending end thereof. The discharge straw transporting device 11 is connected to the apparatus. With this configuration, the problem that the driving force of the waste straw transporting device 11 decreases with an increase in the load on the handling cylinder 4 is eliminated.

As shown in FIGS. 2 to 5, both ends of the arc-shaped receiving net 56 along the lower surface side of the handling cylinder 4 in the front-back direction (direction of the handling cylinder axis P) are provided on the lower case 16 side. The first and second net receiving support portions 57a and 57b of the frame-shaped receiving net guide 57 are separately supported. The first and second receiving net support portions 57a,
The ends of the handle 57b on the side opposite to the handle 13 are frame members 5
Upper case 15 which is connected at 8 and supports the handling cylinder 4
Are supported via front and rear support members 59 and 60 bolted to the frame member 58 so as to be able to open and close and swing around the axis Q of the first transmission shaft 12. That is, the front and rear support members 59 and 60 are provided with through-holes 59a and 60a as bearing portions of the first transmission shaft 12 so as to be located on the shaft core Q, and the first transmission shaft 12 is provided with bearings. The upper case 15 is supported by the first transmission shaft 12 via a pair of front and rear connecting plates 62 provided at the end of the case opposite to the opening 13.

As described above, the front and rear support members 59, 6
0 is fixed to the integral frame member 58 by bolts, the rigidity around the support members 59 and 60 is increased, and even if the upper case 15 is repeatedly opened and closed, both support members 59 and 6 are fixed.
Twisting between 0 is less likely to occur.

The front support member 59 is provided on the first transmission shaft 12.
And a second transmission shaft 61 on the driving part side, which is formed in a transmission case for interlocking connection, thereby achieving a compact structure.

As shown in FIG. 2, the spike transport mechanism 10 is configured by winding a chain 24 with triangular locking claws over a plurality of rings 23, and the transport path of the feed chain 2 in plan view. And almost orthogonally. The drive system of the stock transfer mechanism 9 and the tip transfer mechanism 10 is connected to the extending end of the first transmission shaft 12 for driving the handle cylinder via a bevel gear mechanism 26 so that the ring body of the stock transfer mechanism 9 is 21 are connected in an interlocking manner, and the lower wheel body of the ear tip transfer mechanism 10 is connected in an interlocking manner.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
