By the way, in the conventional work machine as described above, maintenance may be performed with respect to the cooling fan arrange|positioned between an engine and a radiator. In such a case, the radiator is separated from the body for each frame, exposing the cooling fan located on the engine side.

However, in the prior art, since the pipe connecting the intercooler and the engine is supported through the frame, the movement of the frame is regulated by the pipe in the state as it is, and the frame cannot be moved. Therefore, before removing the radiator or the like, it is necessary to separate the pipe. However, whenever maintenance of the cooling fan arrange|positioned between an engine and a radiator is performed, it is troublesome to perform attachment and detachment of piping, and there exists room for improvement in the point of maintainability.

In view of the above situation, it has been desired to provide a working machine capable of easily maintaining the cooling fan disposed between the engine and the radiator.

In addition, with the mowing operation, dust such as fine straw shavings may fall to the lower side of the inlet plate through the gap between the mowing conveyance unit and the threshing apparatus. It may be deposited on the flat surface portion in the lower space. And in this kind of combine, an oil tank etc. may be arrange|positioned, using the space below the inlet plate effectively. In such a configuration, in particular, there is a high risk that straw debris is deposited on the upper surface of the oil tank having a flat and large area.

When straw debris is deposited on the flat surface portion in the space below the inlet plate in this way, the accumulated straw debris is attracted by the wind and scattered to other parts of the aircraft, for example, the boarding operation unit or a belt-type powertrain, causing adverse effects. There was a fear of giving

In order to avoid this disadvantage, it is conceivable to provide a configuration for preventing straw debris from being deposited on the lower side of the inlet plate. However, since the lower side of such an inlet plate is covered by the transfer end part and the inlet plate of the mowing transfer part, the upper side is covered. It needs to be assembled beforehand. Then, when the threshing unit is assembled after attaching the member for preventing the accumulation of straws to the lower portion of the inlet plate, the member for preventing the accumulation of straw and the inlet plate provided in the threshing unit may interfere and be damaged.

Then, while the assembly operation|work of a harvesting|reaping conveyance part and a threshing part can be performed favorably, preventing that straw shavings accumulates in the space below an entrance plate was calculated|required.

The present invention relates to an engine, a radiator disposed outside the body of the engine, a cooling fan disposed between the engine and the radiator, a frame supporting the radiator, and an intercooler supported at a location outside the body in the frame and a pipe connecting the intercooler and the engine, and having flexibility and shape retaining properties disposed so as to penetrate the frame in an inside and outside direction of the body, the frame having a body part supporting the intercooler, and the pipe A supportable support portion is provided, the frame is configured to be oscillating around a pivotal axis, and the support portion is in a support state supported by the main body portion and a support release state in which the support state is released; It is configured to be changeable.

According to the present invention, by setting the support release state in which the support part is not supported by the main body part, the pipe is in a state in which the main body part is not supported, and the main body part and the pipe can move freely with each other. In other words, since the movement of the frame is not regulated by the piping, without separating the piping from the intercooler, bending the piping and swinging the frame around the rotational axis to expose the cooling fan located on the engine side for maintenance. can

Therefore, according to the present invention, it is possible to easily maintain the cooling fan disposed between the engine and the radiator while supporting the intercooler on the frame supporting the radiator and also serving as the supporting member.

According to this configuration, the support portion can be detached from the pipe by a simple operation of separating the first member and the second member from each other. Accordingly, when the frame is oscillated around the rotational axis, the pipe is not caught by the support part, and the pipe can be freely deformed without being restricted by the support part, and it becomes possible to smoothly perform the swinging operation of the frame.

In the present invention, the pipe is provided with an outgoing pipe for introducing compressed air into the intercooler, and a return pipe for deriving the compressed air cooled from the intercooler, wherein the outgoing pipe and the return pipe are arranged in a horizontal arrangement, , it is suitable if the first member and the second member are constituted so as to be vertically divided.

According to this configuration, the first member and the second member covering the periphery of the outgoing pipe and the returning pipe arranged in a lateral arrangement are vertically separable. Accordingly, the first member and the second member make it possible to cover the entire perimeter of the outgoing pipe and the returning pipe without unreasonableness, so that the airtightness of the frame can be secured with a small number of parts.

In this invention, if the said support part is provided in the upper end part of the said frame, it is suitable.

According to this configuration, since the support portion is located at the upper end portion of the frame, the piping capable of supporting the support portion is compactly arranged, and furthermore, access from the upper side to the support portion is facilitated, and the support portion is placed in a supported state and a supported state and in an unsupported state. to make it easier to perform the operation to change the
