Description

The present invention relates to a combine equipped with a radiator.

A conventional combine is described in, for example, Patent Document 1. The combine described in the same document includes a radiator frame that supports the radiator, an air-cooled cooling device (“oil cooler” in the same document) located outside the radiator body, and a refrigerant of the cooling device that is connected to the cooling device. A plurality of hoses (“plumbing hoses” in the same document) for transferring the radiators are provided.

Japanese Unexamined Patent Publication No. 2012-13324

However, in the conventional technology, since the hose connected to the cooling device has a structure that can move freely, the hose tends to flutter due to vibration of the traveling machine body during work, for example. As a result, there is a risk that the hose may come into contact with other members and wear, or the hose may move, which may cause inconveniences such as a load being easily applied to the mounting location of the cooling device.

In view of the above circumstances, there has been a demand for a combine capable of holding the hose connected to the cooling device in a suitable position.

The combine of the present invention
With the radiator
A radiator frame that supports the radiator and
An air-cooled cooling device located on the outside of the radiator body,
A plurality of hoses connected to the cooling device to transfer the refrigerant of the cooling device are provided.
The radiator frame is provided with an opening that penetrates the inside and outside of the machine.
A plurality of the hoses are passed through the opening,
A cover having a through hole formed in a shape along the outer shape of the hose and penetrating the hose along the inside and outside of the machine can be attached to the outside of the body of the opening .
An openable and closable dustproof case covering the radiator and the cooling device is provided.
The cover can be attached to the radiator frame.
Wherein in the closed state of the dust-proof case, the cover is shall be sandwiched between the radiator frame and the dust-proof case.

According to the present invention, by providing the radiator frame with a relatively large opening, for example, the radiator frame is provided with an insertion hole having a size substantially the same as that of the hose, and the hose is inserted into the insertion hole. It becomes easier to route the hose connected to the device. Further, by passing the hose through the through hole of the cover and attaching the cover to the outside of the machine body of the opening, the cover can block the extra portion of the opening and the cover can suppress the movement of the hose. As a result, for example, it is possible to prevent the hose from fluttering due to vibration of the traveling machine body during work, and to avoid inconveniences such as wear of the hose and a large load applied to the mounting location of the cooling device.
Therefore, according to the present invention, the hose connected to the cooling device can be preferably held in position.

Further , according to this configuration, the cover is held so as not to move by sandwiching the cover between the dustproof case and the radiator frame by using the dustproof case, so that a special member for attaching the cover to the radiator frame becomes unnecessary. , It has a simple structure.

In the present invention
It is preferable that the radiator frame is provided with a plurality of the openings.

According to this configuration, since multiple hoses are divided into separate openings and passed through, the possibility that the hoses are twisted or accidentally routed while crossing each other is reduced, and the hoses are routed. It will be easier to work.

The hose on one side and the hose on the other side connected to the second cooling device are located.
The hose on one side of the first cooling device and the hose on one side of the second cooling device are passed through the first opening of the plurality of openings.
It is preferable that the hose on the other side of the first cooling device and the hose on the other side of the second cooling device are passed through the second opening of the plurality of openings.

According to this configuration, one hose of the first cooling device and one hose of the second cooling device located close to each other are passed through the same first opening, and the other side of the first cooling device located close to each other. The hose and the hose on the other side of the second cooling device are passed through the same second opening. As a result, mistakes such as erroneously arranging the hose on one side and the hose on the other side intersecting each other or passing the hose through an uncorresponding opening are less likely to occur, and the hose arranging work becomes easier. ..
