BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to the drawings. 1 is a machine frame of a normal combine machine, 2 is a traveling device provided under the machine frame 1, and 3 is provided on the machine frame 1. The threshing device, 4 is a control unit provided in front of the threshing device 3, and 5 is a cutting unit provided in front of the control unit 4. The reaper 5 has a reel 6 that rotates to a position above its tip.
The cutting blade 7 is provided below the reel 6, and the auger 8 for collecting the cut grain culms is provided behind the cutting blade 7. The auger 8 is mounted on a table 9, and the table 9 surrounds the left and right sides of the auger 8 and the lower part and the rear of the auger 8. The table 9 has a starting end of a carrier device 10 for putting all the cut grain culms into a threshing chamber of the threshing device 3. Parts are attached, and the terminal end of the transport device 10 is connected to the threshing chamber 11 of the threshing device 3.

The threshing chamber 11 of the threshing device 3 is provided with a screw type handling barrel 12 for threshing the introduced grain culms. 1
3 is a handling net, 14 is an oscillating sorting device provided in the wind selection chamber 15, 1
6 is a blast bun, 17 is a first conveyor, 18 is a second conveyor, 19 is a gren tank, 20 is a fried device for fried the grains in the gren tank 19, and 21 is an discharge auger. The transfer device 10 has a well-known configuration, and the endless belt 2 in which a plurality of transfer bodies 24 are provided in a transfer case 23 having a rectangular tube shape.
5 is laid around to construct a so-called ordinary combine that conveys all the cut grain culms and puts them in the threshing chamber of the threshing device 3 to thresh.

Therefore, the carrying device 10 is constructed so as to be rotatable up and down together with the carrying case 23 around the horizontal shaft 26 provided on the front side of the threshing device 3 together with the mowing section 5, and the carrying case 23 is The vertical axis 30 is provided between the side surface 27 on either the left or right side and the front side of the front plate 28 of the threshing device 3 so as to be rotatable outward. for that reason,
The mowing unit 5 and the transport case 23 rotate outward about the vertical axis 30 to expand the space around the mowing unit 5 and the transport case 23, and facilitate maintenance work such as inspection and repair. Further, since the vertical axis 30 is provided between the side of the side surface 27 on either the left or right side of the transport case 23 and the front side of the front plate 28 of the threshing device 3, the turning radius of the mowing unit 5 is set. Make it bigger,
It is suitable because it can be widely opened with a small rotation angle.

Although a concrete supporting structure of the vertical axis 30 is arbitrary, a stay 31 is provided on the side surface 27 of the carrying case 23, and the base of the stay 31 is supported by the vertical axis 30 on the supporting member 3.
2, the support member 32 is attached to the threshing device 3 so that the vertical axis is rotatable.
It is fixedly attached to an arbitrary threshing part front side fixing portion 33 such as the front plate 28 of the above. Similarly, the specific support structure of the horizontal shaft 26 is arbitrary, but the horizontal shaft 26 also serves as the rotation shaft of the upper ring member 35 around which the endless belt 25 is wound, and one end of the horizontal shaft 26 has the tip of the stay 31. When the shaft is mounted on the horizontal shaft 26, the horizontal shaft 26 is supported by the vertical shaft 30 and the support member 32 via the stay 31, and a strong support structure is provided. Further, the horizontal axis 26 and the vertical axis 30 can be supported by the same portion, and the supporting portion can be made compact, which is preferable.

Therefore, the tip (front end) of the lower support 36 is attached at an intermediate position between the start end and the end of the transport case 23, and the base of the lower support 36 is attached to the lower stay 37 by the attachment shaft 38. The lower stay 37 is attached rotatably up and down, and the lower stay 37 is rotatably attached to the lower support member 39 provided below the support member 32 by a lower vertical axis 40.
When 0 is arranged on the same straight line as the vertical axis 30 in a plan view (concentric state), the conveying device 10 and the mowing unit 5 are laterally rotated about the same center, and the lateral direction of the mowing unit 5 is achieved without a complicated structure. The load at the time of rotation can be supported by the rotation support mechanism 41 by the two upper and lower supports (the stay 31 and the lower stay 37 and the support member 32 and the lower support member 39), and the cost is reduced.
Further, when the lower support 36 is configured to be extendable / contractible in the length direction, the mowing unit 5 and the transport device 1 are not detached.
It becomes possible to rotate up and down around 0 as the center of the horizontal axis 26, so that both the lateral rotation work and the vertical rotation of the reaper 5 and the transfer device 10 become easy. Even if the lower support 36 is not configured to be expandable and contractible, it may be detachable and may be attached only when the side support is rotated.

Therefore, the reaper 5 and the transfer device 10
Is moved up and down by a mowing section vertical cylinder 44 provided between the carrier device 10 and a fixed part such as the machine frame 1 or the threshing device 3, and the mowing section upper and lower cylinder 44 is positioned from the left and right center of the carrier case 23 in plan view. Installed at a position close to one side to facilitate maintenance work such as inspection and repair. That is, in the past, the maintenance work was troublesome because it was provided at a position below the left and right center of the transport case 23, but the reaper section vertical cylinder 44 is located on either side of the left and right center of the transport case 23 in plan view. By providing it in a close position, maintenance work is facilitated.

In particular, when it is located on the side of the side surface 27 of the carrying case 23 in plan view, it becomes easier. In the above case, when the tip of the rod 45 of the mowing section vertical cylinder 44 is attached to the transport case 23, and the base of the cylinder section 46 is attached by the attachment shaft 47 arranged concentrically with the vertical axis 30, the mowing section vertical cylinder 44. This is preferable because the carrier device 10 and the reaper 5 can be turned sideways without removing the device, and the side turning work can be facilitated. That is, the reaper section vertical cylinder 4 is simply provided between the carrier device 10 and the machine body frame 1.
4 is provided, the presence of the mowing section vertical cylinder 44 interferes with the lateral rotation of the mowing section 5 and the transport device 10 about the vertical axis 30. When the vertical axis is attached by a mounting shaft 47 arranged concentrically with the vertical axis, the cutting unit 5 and the conveying device 10 can be rotated sideways without removing the cutting unit vertical cylinder 44, and a lateral rotation operation can be performed. The workability can be improved.

The base of the mowing section upper and lower cylinder 44 is rotatably mounted on the vertical axis by a mounting shaft 47 arranged concentrically with the vertical axis 30, and after the lateral cutting of the mowing section 5 and the carrier 10. When the reaper section vertical cylinder 44 is also configured to be extendable and contractible, the reaper section 5 and the transport device 10 are laterally rotated, and in this state, the reaper section vertical cylinder 44 can be contracted and the reaper section 5 can be grounded, It is suitable. In addition, if the mowing unit 5 is grounded after the lateral rotation, the mowing unit 5 and the transfer device 10 are stabilized, maintenance is facilitated, and the configuration of the rotation support mechanism 41 is simplified, which is preferable. In this case, the operability is improved by allowing the reaper 5 to be moved up and down by the reaper up / down lever provided in the control unit 4 while the reaper 5 and the transfer device 10 are laterally rotated and opened. It is suitable.

That is, when the reaping unit 5 and the carrier device 10 are pivoted sideways to open, the reaper up / down lever provided in the control unit 4 lowers and installs the reaping unit 5 for maintenance, etc. Moves the cutting unit 5 upward about the horizontal shaft 26, and then rotates it to return it to the original working position. In the above case, if the reaper section vertical cylinder 44 is configured to also serve as the lower support 36, the number of parts can be reduced, the cost can be reduced, and the weight can be reduced. That is, the base of the reaper section vertical cylinder 44 is attached to the lower stay 37 by the mounting shaft 38.
When the lower stay 37 is attached to the lower support member 39 so as to be rotatable in the vertical axis by the lower vertical axis 40, the lower support 36 is omitted, and the upper and lower parts of the mowing unit 5 and the transfer device 10 are vertically attached. It has a rational structure that can handle both rotation and side rotation.

Thus, the carrying case 23 of the carrying device 10
At the connecting portion between the end and the threshing device 3, the front plate 28 is formed with an insertion port 50 opened so that the end of the transport case 23 fits, and the left and right width of the insertion port 50 is the transport case 23. The end portion 51 of the transport case 23 is formed with an allowance for rotation, and on the opposite side of the insertion port 50 where the vertical axis 30 is provided, the end portion 51 of the transport case 23 is aligned with the movement locus of the end portion 51 after being viewed in a plan view. A plate-shaped closing body 52 is provided so as to be inclined so as to protrude inward as it reaches the side. The closing body 52 is the insertion port 50.
It is formed in the vertical direction to prevent the grains from leaking from the threshing chamber. In the figure, 55 is a crawler of the traveling device 2, 56
Is a transmission case, 57 is a belt for transmitting rotation from the transmission case 56 to the horizontal shaft 26 in synchronism with the traveling speed, and 58 is a clutch 58 for contacting and separating from the belt 57.

With the above structure, the engine is started,
When the machine is run by the traveling device 2, the reel 6 rotates, scrapes the uncut culms, cuts the scraped grain stalks with the cutting blade 7, collects the harvested grain stalks with the rotating auger 8, and conveys the device. Then, the transport device 10 transports the grain culms to the threshing chamber, inputs and feeds them, and the threshing device 3 threshes them.
