Description

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

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

JP 2012-130324 A

  However, in the conventional technology, the hose connected to the cooling device has a structure that can freely move. Therefore, for example, the hose is likely to flutter due to vibration of the traveling machine body during work. As a result, the hose may come into contact with other members and wear, or the hose may cause a disadvantage that a load is easily applied to the mounting portion of the cooling device.

  In view of the above circumstances, there has been a demand for a combine that can suitably hold the hose connected to the cooling device.

The combine of the present invention is
With radiator,
A radiator frame for supporting the radiator;
An air-cooled cooling device located outside the radiator body;
A plurality of hoses connected to the cooling device and transferring refrigerant of the cooling device, and
The radiator frame is provided with an opening penetrating along the direction outside the body,
A plurality of the hoses are passed through the openings;
A cover having a through hole that is formed in a shape along the outer shape of the hose and penetrates the hose along the outside of the body is attachable to the outside of the body of the opening.

According to the present invention, by providing a relatively large opening in the radiator frame, for example, compared to a case in which an insertion hole of approximately the same size as the hose is provided in the radiator frame and the hose is inserted into the insertion hole. It becomes easy to route the hose connected to the device. Furthermore, by passing the hose through the through-hole of the cover and attaching the cover to the outside of the body of the opening, the cover can block the excess portion of the opening, and the movement of the hose can be suppressed by the cover. As a result, for example, the hose is prevented from fluttering due to vibration of the traveling machine during work, and inconveniences such as wear of the hose and a large load applied to the mounting portion of the cooling device can be avoided.
Therefore, according to the present invention, the hose connected to the cooling device can be suitably held in position.

In the present invention,
A dustproof case that can be opened and closed to cover the radiator and the cooling device is provided,
The cover is attachable to the radiator frame,
It is preferable that the cover is sandwiched between the dust-proof case and the radiator frame with the dust-proof case closed.

  According to this configuration, since the cover is held so as not to move by sandwiching the cover between the dust-proof case and the radiator frame using the dust-proof case, a dedicated member for attaching the cover to the radiator frame is not required, and it is simple. Structure.

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

  According to this configuration, since a plurality of hoses are passed through separate openings, the possibility that the hoses are twisted or mistakenly routed while crossing each other is reduced. It becomes easy to work.

In the present invention,
A plurality of the cooling devices are provided in different sizes,
The plurality of cooling devices are arranged closer to the opening as the cooling device is smaller in size,
Between the one hose connected to the first cooling device of the plurality of cooling devices and the hose on the other side, the size is smaller than the first cooling device of the plurality of cooling devices. The one hose and the other hose connected to the second cooling device are located,
The one side hose of the first cooling device and the one side hose of the second cooling device are passed through the first opening of the plurality of openings,
It is preferable that the other hose of the first cooling device and the other hose of the second cooling device are passed through the second opening of the plurality of openings.

  According to this configuration, the hose on one side of the first cooling device and the hose on one side of the second cooling device that are close to each other are passed through the same first opening, and the other side of the first cooling device that is close to each other. This hose and the other hose of the second cooling device are passed through the same second opening. This makes it difficult to make mistakes such as mis-routing with the hose on the one side and the hose on the other side crossing each other or passing the hose through a non-corresponding opening, making it easier to route the hose. .
