Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a riding type combine harvester in which a reaping pretreatment device and a control section are arranged side by side at the front of the machine and a threshing device at the rear of the machine.

In combine harvesters, in order to reduce the economic burden on farmers, it is generally desirable to remove the reaping pretreatment device and threshing device from the fixed frame equipped with the traveling device so that the traveling device can be used as a transport vehicle. .

However, as a conventional technology that can meet this demand, for example, the ``combine attachment/detachment device'' proposed in Japanese Utility Model Application Publication No. 159934/1983,
The entire combine is constructed so that it can be divided into a processing section in which a reaping device, a threshing device, etc. are assembled into a unit, and a traveling section in which a driving section and a control section are assembled into a traveling device to form a unit. This type of combine harvester was designed so that only the section moved under its own power and was extracted from the rear of the machine relative to the processing section, so it became a walk-behind combine harvester with a driving section and a control section at the rear of the reaping pre-processing device and threshing device. However, there was a drawback that it could not be applied to the riding-type combine harvester of the above-mentioned configuration, which is the mainstream of today's combine harvesters.

In other words, in the above-mentioned riding type combine harvester, even if the entire combine is configured so that it can be divided into the processing section and the running section, and only the running section is configured to be able to run under its own power, the processing section The lower end of the reaping pre-processing device in is located in front of the traveling device in the traveling section and protrudes close to the lower end of the traveling device, and furthermore, the control section in the traveling section is located in front of the threshing device in the processing section. Therefore, it is impossible to separate the traveling section and the processing section even if the traveling section is made to travel under its own power in either the forward or backward direction.

The present invention has been made in view of the above-mentioned circumstances, and is a riding-type combine harvester, which is configured to be separable into a traveling part and a processing part by the traveling part running under its own power, and has a combine harvester form and a transport vehicle form. The purpose is to make it easy to switch between the two.

The technical means taken by the present invention to achieve the above object is a riding-type combine harvester in which a reaping pre-processing device and a control section are installed side by side in the front part of the machine body, and a threshing device is provided in the rear part of the machine body. , traveling gear and control section,
A removable frame equipped with the reaping pre-processing device and the threshing device is removably mounted and fixed at the rear in the direction of movement of the machine, on the upper part of the fixed frame equipped with a driving section located near the control section. , the reaping pre-processing device is pivotally supported to the removable frame so as to be able to swing about the vertical axis, and is retracted to a position that does not overlap with each of the components provided on the fixed frame when viewed in the direction of travel; It is possible to obtain the following effects.

That is, a reaping pretreatment device and a threshing device are installed on a removable frame that can be attached to and detached from a fixed frame on the side of the traveling device, and the reaping pretreatment device and threshing device are integrated into a unit, which can be used to adjust the cutting height, etc. Since it is planned to be moved, we will take advantage of the characteristics of the reaping pre-processing device, which is configured to be easy to move, such as being connected to the main frame by just one main frame. This problem solves the problem that is unique when switching to a transport vehicle configuration, since each component overlaps in the front and rear directions of the aircraft, making it impossible to separate the traveling part and the processing part by the traveling part running on its own. Since the problem was solved by changing the position of the reaping pre-treatment device, there is an advantage that it is possible to switch the traveling part of a riding combine harvester to a transport vehicle mode by running on its own with a very simple modification.

Furthermore, when changing the position of the reaping pre-processing device, the reaping pre-processing device is not removably attached to the threshing device or moved by sliding, but rather by swinging around the vertical axis. Since the position can be changed easily,
There is also the advantage that when returning the reaping pretreatment device to its original position, it can be easily positioned relative to the threshing device.

Hereinafter, embodiments of the present invention will be described based on the drawings. A riding combine harvester is equipped with a crawler type traveling device 1, and has an engine-related 2 and a transmission case 3 of the traveling device 1 at the front thereof.
