Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized in that a threshing device and a tank for storing future grain are arranged side by side, and the tank is placed at the left and right end of the farthest side from the threshing device. The structure is configured so that it can swing freely left and right outwards around an up-down axis that passes through a point near the front and rear ends of the tank and near one end of the tank, and the stored grain in the tank is placed at a position higher than the tank. This invention relates to a mobile threshing machine in which a thrower for lifting and transporting grains is attached to swing together with a tank.

[Prior Art] In a conventional mobile threshing machine of this type, by removing the thrower tube from the thrower case in which the blades of the thrower are housed, the connection between the thrower tube and the stay that swingably supports the upper part of the tank is established. It was designed to allow the tank to swing outward to the left and right while avoiding this problem (for example, in the 1980s
110555).

[Problem that the invention attempts to solve]

However, when using the conventional mobile threshing machine, the thrower cylinder must be removed each time the tank is swung left and right.
The drawback was that it lacked workability when performing maintenance on the threshing device by opening the sides of the threshing device by swinging the tank left and right outward.

The purpose of the present invention is to eliminate such conventional drawbacks.

[Means for solving problems]

The characteristic configuration of the mobile thresher according to the present invention, which was taken to achieve the above object, is that the stay that swingably supports the upper part of the tank is moved out of the swinging path of the thrower tube in the thrower that swings integrally with the tank. The function and effect are as follows.

[Function] The stay that swingably supports the upper part of the tank is located outside the swinging path of the thrower cylinder to avoid collision between the stay and the thrower cylinder that would occur when the tank swings outward from side to side. Since the tank is allowed to swing outward to the left and right, there is no need to remove the thrower cylinder when swinging the tank outward to the left and right.

[Effect of idea]

As a result, it has become possible to improve the workability of maintenance of the threshing device by swinging the tank left and right outward.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 2, a threshing device 2 and a tank 3 for storing grains to be sent out are mounted side by side on a machine frame equipped with a crawler traveling device 1, and the front part of the machine frame A reaping section 4 is connected to the rear part of the tank 3,
A thrower 5 for lifting and carrying out the grain in the tank 3 is installed so as to be able to swing freely around the axis of the thrower blade, and between the tank 3 and the reaping section 4,
A combine harvester is configured by providing a driver's seat 6.

The thrower cylinder 5A of the thrower 5 has an upper half cylinder portion 5.
a and a lower half cylinder part 5b, and the upper half cylinder part 5a can be freely switched between an upright position connected to the lower half cylinder part 5b and a horizontal position lying down on the tank 3. It is attached to the lower half cylinder portion 5b.

As shown in FIG. 1, the tank 3 is configured to be able to swing outward to the left and right about an up-down axis a passing through a location near the outer end and a location near the rear end. The stay 7, which is fixed at one end to the rear of the threshing device 2 and swingably supports the upper part of the tank 3 at the other end, is located outside the swing path of the thrower cylinder 5A that swings together with the tank 3. It is made up of folds.

A mechanism 8 for fixing the tank 3 in a storage position along the threshing device 2 is arranged so that the swinging free end of the tank 3 and the threshing device 2 are aligned with the same vertical axis when the tank 3 is swung into the storage position. The cylindrical members 9 and 10 located at
Attach it so that the one on the tank 3 side is located on the upper side, and when these cylindrical members 9 and 10 are located on the same vertical axis, insert it downwardly so that it does not come off across both cylindrical members 9 and 10. This is a means for providing a pin 11 to prevent the tank 3 from swinging. A lower opening of the upper cylinder member 9 on the tank 3 side is opened so as to allow the pin 11 to protrude below the upper cylinder member 9 by movement along the tank swing direction. A slide member 13 is attached to the slide member 13, which can be freely changed between a closed position and a closed position to prevent the pin 11 from protruding downwards, and is biased to the closed position via a spring 12. 13 is provided with a hit 14 that moves the slide member 13 to the open position by being pressed by the lower cylindrical member 10 on the side of the thresher 2 as the tank 3 swings to the storage position. There is. In other words, when the tank 3 is swung to the storage position with the slide member 13 in the closed position and the pin 11 inserted and held in the upper cylinder member 9, the slide member 3 moves toward the lower cylinder member 10.
When the pin 11 is inserted into the lower cylindrical member 10, the tank 3 is automatically fixed in the storage position.

Claims (1)

[Scope of utility model registration request] A threshing device 2 and a tank 3 for storing future grain are arranged side by side, and the tank 3 is located near the left and right ends on the side far from the threshing device 2.
In addition, it is configured to be able to swing outward to the left and right around an up-down axis a passing through a point near one front and rear end, and the stored grain in the tank 3 is placed at a position higher than the tank 3 at one front and rear end of the tank 3. In a mobile threshing machine in which a thrower 5 for lifting and carrying out is mounted so as to swing together with the tank 3, a stay 7 that swingably supports the upper part of the tank 3 is attached to the thrower 5 that swings together with the tank 3. The movable thresher is located outside the swinging path of the thrower cylinder 5A in No. 5.
