Means for Solving the Problems The present invention is mounted on a machine base.
Discharged from the threshing device 2 at the rear of the threshing device 2
A hatch that can be turned horizontally around the tip of the straw
Ter 5 is provided, shredding straw discharge by opening and closing switching changeover plate 8 provided on the upper surface of the cutter 5 provided straw discharge conveyor 4 to Ri Wataru from the exhaust straw outlet of the threshing device 2 at the top of the cutter 5 by a cutter 5 processing or, to process and carried out to the rear than the cutter 5
In such a combine, the holding rail 7 opposed to the transport surface of the transport chain 6 of the straw transport device 4 is constituted by a front fixed rail 7a and a movable rail 7b which moves forward and backward with respect to the fixed rail 7a. And the movable rail 7b
A single operating tool provided in the driving unit via a plurality of links
And the tip of the straw in the vicinity of the cutter 5
The above-mentioned problem has been solved by interlockingly connecting the link located on the direction side and the switching plate 8 via the operation wire 32.

[0005]

[Effect] The straw that has been threshed by a threshing device and discharged from the culm opening is conveyed backward by a straw conveying device, and when the straw is shredded by a cutter, the operating tool is moved to one side. When operated, on the one hand the movable rail is pushed forward via the link and the rear end retracts from above the cutter, and on the other hand the switching plate opens via the operation wire,
The transported straw is shredded by a cutter. In addition, when the conveyed straw is to be processed by a notter or a dropper at the rear thereof without shredding, when the operating tool is operated on the other side, the movable rail is pulled rearward via a link, and the switching plate is moved. The cutter pivots downward through the operation wire to close the supply port of the cutter. Further, when performing maintenance and inspection of the sorting unit of the threshing device, the cutter is horizontally turned sideways around one side thereof. At this time, the cutter performs a turning operation, but since the operation transmitting means of the switching plate is constituted by an operation wire, the cutter is smoothly turned only by being deformed in accordance with the turning.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described. A threshing device 2 is mounted on one side of a machine having a traveling device 1 composed of a crawler, and an operation panel is sequentially provided on the other side from the front. And a driving section including a driver's seat and a lever panel,
A grain tank 3 and an engine are provided, and in front of the threshing device 2, a harvesting device, and a grain culm transport device that transports the harvested grain culm rearward while adjusting the handling depth and supplies the harvested culm to the threshing device 2. Is installed. In addition, one side of the disc-shaped cutter 5 is hinged to the rear part of the threshing device 2 so as to be able to turn horizontally, and the other side is connected so as to be able to be disengaged from the threshing device. Transport chain 6
There is provided a straw transporting device 4 including a holding rail 7 provided on the lower surface thereof.

The holding rail 7 is composed of a fixed rail 7a elastically held on a top plate of a dust separation chamber and a movable rail 7b slidably fitted to a rear portion thereof. plate 8 is fixed separately to the stock based on the switching unit and the ear-side switching unit to pivot shaft 10 which is rotatably supported on the rear portion of the supply port, the ear-side end portion of the pivot shaft 10, the arm 11 Is fixed.

A lever box 13 is provided near the front of the side surface of the grain tank 3 immediately behind the driver's seat, the lever box 13 pivotally supporting the operation lever 12 so that the operation lever 12 can be tilted back and forth, and the operation lever 12 is linked to the movable rail 7b. The link mechanism includes a rod 15 having a turnbuckle 15a and a telescopically adjustable rod 15 and a bracket 16 fixed to a rear portion of the side surface of the grain tank 3.
And a vertical shaft 21 rotatably inserted into a support cylinder 20 which is integrally supported with a bracket 19 extending from an engine cover 18.
A link 22 fixed to the upper end of the shaft , a rod 24 connecting the link 22 to the rear of the link plate 17,
And links 23 fixed to the first lower end grain tank 3 side, immediately
Is located on the tip side of the straw discharged from the threshing device 2
A link plate 26 which is provided in the front-rear direction and is pivotally supported on a top plate; a link 25 having one end of the link plate 26 connected to the link 23; a There strain base side of the straw discharge the arm 27 in tandem to the pin 7c projecting from the rear end lower surface of the movable rail 7b
The link mechanism is generally reversed in plan view as a whole.
They are arranged in an L shape. The arm 27 has an elastic plate 27a and an elongated hole 27b fixed thereto, as shown in FIG.
The long hole 27b is slidably fitted to the pin 7c, and is provided with a pin 7c.
A roller is interposed between c and the long hole 27b so as to be easily slid. When the amount of straw changes and the holding rail 7 moves up and down, the elastic plate 27a is deformed and is When the movable rail 7b is pushed into the lower end of the pin 7c while keeping the linked state, the stopper 2 which comes into contact with the rear wall of the threshing device 2
8 is attached. Reference numeral 29 denotes an elastic plate which, when the movable rail 7b is pulled out, presses the movable rail 7b toward the transport chain 6 to improve the nipping and transporting performance.

An operating system for linking the switching plate 8 to an operating lever 12 is provided in the vicinity of the cutter 5 in the direction of the tip of the straw spike.
An operation wire 32 interlockingly connected to the front end of an L-shaped link 31 pivotally supported by a bracket 30 erected on the cutter 5, the middle part of the link 22 pivotally supported by the support cylinder 20, and the L-shaped link 31 An integral rod 31a and the rod 31
a is formed by a tension spring 35 interlockingly connected to a rod 33 integral with the arm 11 of the rotating shaft 10. 36 is a guide plate, 37 is a holding plate, 38
Is a plate.

The threshing device 2 threshes the cereal culm supplied by the pretreatment device, and the straw discharged from the culm opening is pinched by the straw conveying device 4 onto the cutter 5. Conveyed. When shredding this waste straw, when the operation lever 12 is tilted forward, the rod 15
And 24 move forward, and the links 22 and 23 rotate counterclockwise with the shaft 21 in plan view, whereby the link 2
3 rotates the link plate 26 clockwise via the link 25, so that the arm 27 pulls the movable rail 7b forward and pulls it in. On the other hand, the link 22 moves the operation wire 3
2, the front part of the L-shaped link 31 is pulled up, whereby the rod 31a at the lower end of the L-shaped link 31 rotates the rod 33 and the arm 11 forward through the tension spring 35, so that the switching plate 8 Is lifted and opened,
The conveyed straw is supplied to the cutter 5 and shredded.

In addition, when the waste straw is transported backward without shredding and processed by a knotter or dropper,
When the operating lever 12 is tilted backward, the rods 15 and 24 move backward and the links 22 and 23 rotate clockwise, whereby the link 23 moves the link plate 26 via the link 25 counterclockwise. Arm 27 pulls the movable rail 7b backward and moves it to the vicinity of the rear end of the transport chain 6, while the arm 27 pulls the movable rail 7b backward.
2 rotates backward, the operation wire 32 relaxes,
Since the L-shaped link 31 rotates counterclockwise and the tension spring 35 also loosens, the switching plate 8 rotates downward to close the supply port. In this state, the straw conveying device 4 conveys the straw to the rear portion of the cutter and discharges the same. If a notter is attached to the rear portion, the binding process is performed. Furthermore, when the cutter 5 is turned and retracted for maintenance and inspection of the sorting device of the threshing device 2 or the straw conveying device, the turning operation can be easily performed because the operation wire 32 is freely deformed.
