EXAMPLES Next, examples shown in the drawings will be described.
FIG. 1 shows a side view of the combine, and a threshing part B similar to the conventional structure in which an under-chain type feed chain 6, a handling cylinder 7, a swing sorting body 8 and the like are provided on a machine body supported by both crawlers 5. The reaping section A, which is equipped with, and which is continuously provided in front of the threshing section B, has the sward plates 9a and 9b on both front sides, and the cases 10a and 10b are obliquely installed in the rear thereof, and the shunt case 10a, Both scraping wheels 12, 12 are provided in parallel on the upper side of the cutting blade 11 provided in the lower rear part of 10b, and the culm side of the culm is held and conveyed from the upper rear part to the front of the threshing part B. A head carrier 1 having a stocker carrier chain 2 and a sling rod 2b which can be supplied to the starting end of the feed chain 6 and having a tine 1b for carrying the head side on the upper side thereof.
Further, the guide rod 1c is obliquely provided, and the guide rod 1c and the flap 2b are connected to the inverted U-shaped supporting rod 13 extending integrally with the stock carrier 2 and the tip carrier 1. Constitute.

Further, an operating lever 15, a seat 16 and a side column 17 are provided on the front and rear sides and inside of the step 14 which is erected on the right side of the reaping section A, and formed on the outside of the side column 17. An adjusting lever 19 extending from the support rod 13 side is inserted into the guide groove 18 so that the adjusting lever 19 can be engaged therewith, and an engine section E is provided at the rear portion of the seat 16 and a paddy tank 20 is provided behind it. Set up and configure.

In front of the threshing section B, a transmission mechanism described below is provided laterally. On the front right side of the threshing section B, a transmission case 3 having a drive shaft 21 installed therein is provided laterally, and on the outer side of the vertical case section 3a integrally formed at the left end of the transmission case 3 in front of the threshing section B. Attach the case side plate 22 to several bolts 2
3, an input pulley 25 on which a transmission belt 24 from the engine side is mounted is loosely fitted to the outer end which is the right end of the drive shaft 21, and the drive shaft is elastically pressed by a spring 26. Claw type safety clutch 27 that is splined to 21
Is engaged with the boss 25a of the input pulley 25, and is mounted on the transmission shaft 29 in the transmission cylinder 28 that is raised from the transmission case 3 to the right and extends to the case 10b so as to be transmitted from the drive shaft 21 via both bevel gears 30. The cutting blade 11 is installed in the transmission cylinder 31 extending forward from the left side portion of the transmission case 3.
A transmission shaft 32 that transmits power to the scraping wheel 12 and the left raising case 10a is mounted, and the transmission shaft 32 is mounted so that it can be transmitted from the drive shaft 21 via both bevel gears 33.

The front side of the threshing part B is fixed by welding one end side of the support cylinder 34 extending in the axial direction of the drive shaft 21 on the front side of the threshing part B to the outer surface of the one side of the case side plate 22 by welding. A metal 36, which rotatably fits and supports the intermediate portion of the transmission case 3, is mounted on one of the upper and lower supports 35, 35, which is installed on the upper side of the other support 35. The support cylinder 34 is detachably fitted to the metal 37 to be installed.

On the outer surface of the other side of the case side plate 22, one end side of a cylindrical transmission case portion 4 which is parallel to the front upper side of the support cylinder 34 is integrally fixed by welding, and the transmission case is formed. A sprocket 39 fitted to one end of a transmission shaft 38 mounted on the inside of the portion 4 is provided with a chain 41 around the sprocket 40 of the drive shaft 21 in the vertical case portion 3a. Support tube 4 obliquely installed outside the tip of the
A vertical conveyance drive shaft 45, which is obliquely provided to the transmission shaft 38 and is transmission-coupled via bevel gears 43 and 44, is mounted on the support shaft 2, and a support member 46 is provided integrally with the support cylinder 42 in a continuous manner. Is rotatably fitted to the transmission case portion 4 so as not to be disengaged, and the upper side of the tip carrier 1 and the stock carrier 2 is integrated with the support cylinder 42 and the side of the support 46. Drive shaft 45, which is integrally connected to one end side of the support rod 13 and projects to both ends of the support cylinder 42.
The sprocket 1a, 2a fitted at both ends of the head carrier 1 and the stock carrier 2 are installed so that they can be transmitted respectively.

Therefore, it is input from the input pulley 25 and transmitted from the drive shaft 21 to each part of the mowing section A as shown in the transmission diagram of FIG. In this case, the safety clutch 27 slips, interrupts the transmission, and prevents troubles from occurring, and the input pulley 25 of the safety clutch 27 prevents the seat 16 from slipping.
Therefore, the operator can know the operating noise generated by slipping of the safety clutch 27.

If the grain culm is short culm and the adjustment lever 19 is pushed forward and locked, the front parts of the tip carrier 1 and the stock carrier 2 are lowered as shown in FIG. The entire body rotates around the transmission case portion 4, and the cutting blade 1
Therefore, the short culm cut by 1 can be fed to the threshing part B in a deep handle while being conveyed. If the grain culm is a long culm, as shown in FIG. 4, the adjustment lever 19 is pushed backward to rotate the whole body around the transmission case portion 4 while raising the front portion, so that the threshing portion B is shallow. It will be possible to supply it in a handle form.

By the way, when the case side plate 22 is removed from the vertical case portion 3a by removing the bolts 23, the support cylinder 34 and the transmission case portion 4 are moved from the transmission case portion 4 to the tip end carrier 1 in the direction shown by arrow EE in FIG. And the whole of the stock carrier 2 can be removed from the front of the threshing part B without changing the whole, and the rear part of the mowing part A, which is the front of the threshing part B, is opened as shown in FIG. Therefore, the transmission section, the rear of the reaping section A and the front section of the threshing section B can be inspected and maintained, the jammed culms and the like can be removed, or the threshing section B Therefore, it is possible to perform the work of pulling out the swing selection body 8 in the forward direction. It should be noted that only the portion of the case side body 22 on the side where the transmission case portion 4 is fixed can be attached to and detached from the vertical case portion 3a by the bolts 23 (the support cylinder 34 is not detached from the transmission case portion 4 integrally. ) It can be structured.

[0013]

Since the present invention is constructed as described in the claims, it has the following operational effects. The tip carrier 1 and the stock carrier 2 are connected to a vertical transport drive shaft,
It is transmission-coupled to a horizontal transmission mechanism. Since a slide type attachment / detachment mechanism is provided in the transmission connecting portion, the attachment / detachment of both the carriers 1 and 2 is performed by sliding in the same lateral direction as the horizontally arranged transmission mechanism.

That is, the attachment / detachment work can be carried out by the operator moving toward a wide space in the direction opposite to the side where the transmission mechanism is present, and the two carriers can be separated as a unit including the bevel gear transmission mechanism. , The attachment and detachment work can be easily performed, and a wide space can be secured for the inspection and maintenance work after the removal.
