Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing apparatus provided in a combine or the like. 2. Description of the Related Art Conventionally, in a threshing apparatus provided in a combine or the like, there has been a demand for a technique for facilitating maintenance of a threshing chamber and a straw transporting apparatus. There is known a technology in which a handling cylinder mounted between a side moving side plate and a thrusting operation position can be raised from a threshing operation position to a maintenance position, and a lock device that holds the handling cylinder at the threshing operation position is provided. There is also known a technique in which a transport chain of a straw transport device can be raised from a straw transport operation position to a maintenance position. In Japanese Utility Model Application No. 1-117524 (see Japanese Utility Model Application Laid-Open No. 3-56331), which is a prior application of the present invention, a shaft is mounted between a supply side moving side plate and a discharge side moving side plate of a threshing room. And a locking device for holding the handling cylinder at the threshing operation position is provided between the handling cylinder cover and the body-side frame. A technique is described in which a transport chain of a straw transport device provided behind a threshing room can be held at a straw transport operation position via the lock device. When the handling cylinder is moved to the non-threshing position,
The axis of the torso moves upward while maintaining the horizontal state.
It is good. Also, Japanese Utility Model Publication No. 56-55339 discloses that
A threshing room having a handling cylinder suspended by a horizontal axis, and a grain stalk feeding device for nipping and transporting the grain stalks from the front left and right one supply side of the threshing chamber to the front left and right other discharge side. In the threshing apparatus, there is described a threshing machine in which the supply device is opened upward together with a cover plate of the threshing chamber to which the supply device is fixed so that maintenance can be performed. A locking device for holding the handling cylinder at the threshing operation position and a locking device for holding the transport chain of the straw transporting device at the straw transporting position, respectively. If provided independently, during threshing work after maintenance, each locking device must be individually operated to lock, which is inferior in operability in the maintenance,
There is a disadvantage that the work efficiency is reduced. In addition, the handling cylinder is non-threshing
When moved to the working position, the axis of the handling cylinder remains horizontal
It moves upward in the state where
The gap can not be opened greatly, making maintenance easy.
There is a disadvantage that there is no. In addition, 56-55339
In the publication, maintenance of the threshing room is possible because the grain stalk supply device moves up together with the lid plate as the upper cover, but maintenance is impossible because the wind selection room is not opened. In addition, there is also a problem that the handling cylinder may be distorted due to the structure, and when the handling cylinder is configured to move upward, the work is more difficult. The present invention employs the following technical means in order to solve the above-mentioned problems. That is, the threshing room 4 having the handling drum 5 supported by the horizontal shaft 20 and the culm from the supply side 2 on the left and right one side on the front side of the threshing chamber 4 to the discharge side 3 on the other side on the front left and right sides. In a threshing device having a grain culm supply device 37 for pinching and conveying, the supply device 37 includes a chain cover 45 provided on the front side of the supply device 37, a part of the front side of the threshing chamber 4 and the wind selection chamber 1.
1, a front plate 44 forming a part of the front side is attached, and the supply device 37, the chain cover 45, and the front plate 44 are integrally movable. Axle mounting is provided between the moving side plate 21 and the discharge side moving side plate 22 and configured to be movable from a threshing work position to a non-threshing work position,
A lock device 28 for holding the handling cylinder 5 at the threshing operation position
Is provided between the discharge-side movable side plate 22 and the discharge-side fixed side plate 25, and the lock device 28 moves the handling cylinder 5 to the threshing operation position.
After being placed and held, the transfer chain 8 of the
2 so that it can be held at the straw transport work position,
The supply-side movable side plate 21 has a rear edge on the supply-side fixed side.
A structure that is rotatably attached to a plate 23 by a shaft fitting 24.
The discharge side movable side plate 22 is connected to the discharge side fixed side plate 25.
To the axis of the shaft fitting 24
Is inclined so that the front side is low and the rear side is high
When the handle cylinder 5 is rotated, the rotating end of the handle cylinder 5 is rotated.
Is a threshing apparatus characterized in that it is configured to be higher as it is rotated . After the handling cylinder 5 and the transfer chain 82 of the straw transfer device 81 are moved from the working position to perform maintenance, the discharge side moving side plate 22 and the discharge side fixed side plate 25 are prepared for threshing work. The lock device 28 provided between them is locked. Thus, the supply side moving side plate 2 of the threshing room 4
The handling cylinder 5 which is mounted between the first and discharge side moving side plates 22 is
The position is held at the threshing work position. At the same time, the transport chain 82 of the straw conveying device 81 provided at the rear side of the threshing chamber 4 can be held at the straw conveying work position. Further, when the supply device 37, the chain cover 45, and the front plate 44 are integrally moved,
A part of the front side of the threshing room 4 and a part of the front side of the wind selection chamber 11 are opened. Further, the handling cylinder 5 is set to the shaft fitting 24 as an axis.
When it is raised to the non-threshing position, the rotating end of the handling cylinder 5
The higher you move it. As described above, according to the present invention, the supply side movement of the threshing chamber 4 is performed by the locking operation of the lock device 28 provided between the discharge side movable side plate 22 and the discharge side fixed side plate 25. The handling drum 5 mounted between the side plate 21 and the discharge side moving side plate 22 can be held at the threshing operation position, and at the same time, the transport chain 82 of the straw transport device 81 provided at the rear side of the threshing chamber 4.
Will also be able to hold the position at the straw transport work position,
The operability in maintenance can be improved, and the work efficiency can be improved. Furthermore, since the chain cover 45 and the front plate 44 also move simply by moving the supply device 37, the front sides of the threshing room 4 and the wind selection room 11 are opened, and maintenance of the threshing room 4 and the wind selection room 11 is facilitated. Since the stalk supply device 37 moves, the maintenance of the stalk supply device 37 is facilitated. Further, the handle cylinder 5 is not detached around the shaft fitting 24 as an axis.
When raised to the grain working position, the rotating end of the handling cylinder 5 is rotated.
The transfer part with the straw conveying device 81
Is greatly opened, making maintenance easier.
