Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabin device used for combine harvesters.

[0002]

2. Description of the Related Art Conventional techniques, for example, Shoukai 60-19
The cab moving device in the moving crane disclosed in Japanese Patent No. 3873 is configured to be movable up and down while being moved back and forth by a parallel link mechanism and a drive cylinder. However, there is no combination of agricultural machines that moves the cab (cabin) up and down.

[0003]

In this kind of combine, it is required to confirm the position of the grass body with respect to the grain culm row in the lower front part during the work. In particular, when reaching the edge of the field and turning the combine to adjust to the next row of grain culms, the driver should ensure that the tip of the grass body is between the grain culm rows and the grain culm rows. It is required to peep.

In the normal combine construction, since the front part of the cutting and conveying device is high, it is difficult for the driver to visually recognize the tip of the front side grass from the cabin device. Also, the driver needs to check whether the chassis is moving forward along the grain culm row without leaving the planting row of the grain culm even during the mowing threshing operation. There is also a need for equipment inspection.

[0005]

The present invention has taken the following technical means in order to solve the above-mentioned problems. That is, in the chassis 3, the thresher 2 is provided on one side in the traveling direction.
Is provided with a grain tank 8 mounted on the other side, and a cabin 5 having a control seat 4 installed therein is disposed in front of the grain tank 8, and a grain communicating with the grain tank 8 is provided on the side of the cabin 5. A discharge pipe 9 is provided, and a mowing and conveying frame 7 is provided in front of the cabin 5 and the thresher 2 so as to be vertically movable. The cabin 5 is provided with a mowing and conveying frame 7 located at the front side and a Glen tank 8 at the rear side. The lift device 14 is supported so that it can move in the vertical direction without colliding with the grain discharge cylinder 9 on one side.
The combined cabin device is provided between the rear surface of the cabin 5 and the front surface of the Glen tank 8.

[0006]

EXAMPLE First, the structure will be described. Chassis 3
The crawler 10 is provided so that it can travel in a field such as a wet field or a dry field. The threshing machine 2 is, as is conventionally known,
It is composed of a threshing chamber and a sorting chamber, and is mounted on one side of the chassis 3 with the grain culm supply port facing forward. The grain tank 8 is configured to temporarily store the grains that have been threshed by the thresher 2, selected and taken out, and the cabin 5 mounted on the other side of the chassis 3 is provided with the control seat 4 and A control device attached to this is internally mounted and positioned and mounted in front of the Glen tank 8 in the front portion of the chassis 3.

The cabin 5 is attached to a hydraulic lift device 14 which can be moved up and down by hydraulic pressure so that it can be moved up and down. The hydraulic lift device 14
Can be operated from inside the cabin. The reaping transport frame 7 has grain stalks and grass rods arranged at the front end for each row of reaping rows, and a reaping device 1 is provided behind the lower part thereof.
The grain culm conveying frame 7 is provided between the threshing machines 2.

The grain discharge cylinder 9 is constructed so as to rotate freely by connecting the starting end to the lower part of the Glen tank 8 and opening the discharging end at the outside of the machine. Next, the operation will be described. First, the chassis 3 is moved forward to start the mowing and threshing work while starting the prime mover and driving the rotating parts of the machine body.

At this time, the driver operates the hydraulic lift device 14 on the control seat 4 in the cabin to move the cabin 5 upward to a height at which the front end of the grain-separating rod can be visually confirmed. Move to. In this case, the cabin 5 is moved substantially straight up without being largely moved back and forth, left and right by the hydraulic lift device 14, so that there are almost no obstacles such as collision with the front and side reaping transport frames 7 and the like. It is safe and can be climbed without fail.

The work is continued in this way.
Further, when the driver raises the cabin 5 to a high position, the combine harvester reaches the end of the field and turns, and also when the combine rushes into the next harvested grain culm row, the tip portion of the grain culm rod. It is very easy to start the work while aligning the lines between the grain and culm rows.

[0011]

As described above, according to the present invention, the cabin 5 in the combine can be lifted by the lift device 14 and, at the same time, it collides with the reaping / conveying frame 7 and the grain tank 8 located at the front and back when the combiner 5 is lifted or lowered. Since it is a structure that raises almost straight so as not to do so, if the cabin 5 is raised during the mowing threshing work, the tip of the grain culm and weeding rods can be visually checked to make sure that the culm is aligned with the row. There is a feature that can be done.

Therefore, there is a feature that the driver can work along the row of cut culms while surely confirming the front even if the automatic direction control device is not used. Moreover, since the cabin 5 of the present invention hardly moves back and forth or left and right when moving up and down, and can be performed substantially straightly, it is a large-sized one with the control seat 4 and the like built-in, but the reaping and conveying frame on the front side. It has an excellent effect that it can operate safely without colliding with the grain culm raising device 7 and the rear side grain tank 8 and grain discharge cylinder 9. Also,
Since the lift device 14 is provided between the rear surface of the cabin 15 and the front surface of the Glen tank 8 in the traveling direction of the machine body, it is close to the control seat on the side opposite to the threshing machine 2, so the lift device 14 can be quickly inspected. You can start working.
