Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a mowing section on the front side of a machine having a traveling device, a cabin for enclosing an operating device and a seat is provided at the front of the machine behind the mowing section, and a cabin of the cabin is provided. The present invention relates to a riding combine of a type in which a grain tank for temporarily storing harvested grains and a threshing unit for threshing cut culms are arranged in parallel on the rear side.

[0002]

2. Description of the Related Art The riding combine of the above-described type has a mowing section provided on the front side of a machine having a traveling device of a crawler so as to be able to move up and down. A cabin for enclosing the operating device for operation, seats, etc. is provided, and on the rear side of the cabin, a grain tank for temporarily storing the harvested grains and a threshing section for threshing the harvested culms are juxtaposed. Are configured.

Further, the grain tank is provided with a grain discharging device for appropriately discharging the grains stored therein. In the grain discharging device, the base end of the discharge cylinder is connected and communicated with the upper end of the fried food cylinder standing upright near the Glen tank, and the discharge cylinder is swung and raised and lowered by a driving device such as a hydraulic cylinder. It is configured to be possible. The drive device such as the hydraulic cylinder is connected so as to be operated by the operation of an operation device arranged near the seat in the cabin.

The cabin has a transparent window on each of the front side and the side of the body.

[0005]

In a passenger combine harvester, when an operator seated in a cabin intends to turn and lift the discharge cylinder, the operator operates the discharge cylinder while accurately confirming the position of the discharge cylinder. This is important not only in terms of work efficiency but also in terms of safety. However, in the above-described conventional technique, there is a limit to the range in which the position of the discharge tube can be monitored from the windows on the front side and the side sides of the cabin of the cabin, and the blind spot largely remains behind the cabin.

Further, the operating device for the discharge cylinder is merely arranged near the seat, and is not convenient for the operation while monitoring the discharge cylinder from the window of the cabin.
Further, since the operating device for the discharge cylinder is arranged near the seat, the operator carelessly touches the operating device, causing an erroneous operation, which may cause an accident or damage to the device.

[0007]

The present invention takes the following technical means in order to solve the above problems. That is, the reaping unit 2 is provided on the front side of the machine body 1 having the traveling devices 10 and 10, and the cabin 5 for enclosing the operation devices 50 and 50a and the seat 51 is provided in the front part of the machine body 1 behind the reaping unit 2. In a riding combine, which is configured by arranging a grain tank 7 for temporarily storing harvested grains and a threshing section 4 for threshing cut culms on the rear side of the cabin 5, The base end portion of the discharge cylinder 81 is connected and communicated with the upper end portion of the cylinder 80, and the discharge cylinder 8 is connected.
1 is configured so that it can be swung and raised and lowered, and a window 52 is formed on the rear surface side of the cabin 5 and the seat 5
1 The operating device 50a for the discharge cylinder 81 is arranged laterally on the rear side, and the base end of the discharge cylinder 81 and the window 52 on the rear surface side of the cabin 5 are arranged at substantially the same height. This is a riding type combine harvester.

[0008]

The technical means of the present invention thus constructed operates as follows. First, since the base end portion of the discharge cylinder 81 and the window 52 on the rear surface side of the cabin 5 are arranged at substantially the same height, the operator in the cabin 5 turns or discharges the discharge cylinder 81. When attempting to do so, at least the proximal end portion of the discharge cylinder 81 can be monitored from the window 52 on the rear surface side of the cabin 5.

Further, the operating device 50a for the discharge cylinder 81 is
Since it is located on the rear side of the seat 51,
The operating device 50a can be easily operated in a posture in which the base end portion of the discharge cylinder 81 is monitored through the window 52 on the rear surface side of the cabin 5. Further, since the operation device 50a is arranged on the rear side of the seat 51, the operator sitting on the seat 51 naturally positions the operation device 50a on the rear side. This prevents the operator from inadvertently touching the operating device 50a.

[0010]

With the above operation, the technical means of the present invention has the following effects. First, the pilot is in the cabin 5
By being able to monitor the base end of the discharge cylinder 81 from inside, for example,
Even if the whole or the tip of the discharge cylinder 81 becomes invisible, the posture of the discharge cylinder 81 can be grasped from the turning state and the undulating and rotating state of the base end portion, and an accurate operation is performed based on this. be able to.

Further, the operator can operate the operation device 50a easily (in a comfortable posture) while monitoring the base end portion of the discharge cylinder 81, and the operability is improved. Further, since the erroneous operation of the operating device 50a is suppressed, it is possible to prevent the discharge cylinder 81 from inadvertently turning and undulating, and prevent accidents and damage to the device. As described above, the rational arrangement of the window 52 on the rear surface side of the cabin 5, the base end portion of the discharge cylinder 81, and the operating device 50a enables highly efficient work to be performed safely.
