Japanese Patent Application Laid-open No. Hei 8-189357

In the combine comprised as mentioned above, the warm air after performing the said heat exchange cools an engine as it guides along the external shape of an engine, and the temperature further rises. And the warm air (hot air) spreads in various directions. For example, when warm air is injected into the engine bonnet located above the engine, the engine bonnet becomes warm, and the operator in the driving unit may feel hot. Moreover, especially in the combine which does not have a cabin and the rear of an engine room is open, the warm air after engine cooling will turn to the rear side of an engine room, will flow in from a engine room to a driving part, and a driver may feel hot. There is also concern. This is the same even if it is an air-cooled combiner without a radiator, even if it is an air-cooled combiner without a radiator.

An object of the present invention is to provide a combine of a comfortable driving environment by controlling the wind direction of a blowing fan after cooling such as an engine.

Features of the present invention,

 Driver,

An engine located below the driving unit;

A blowing fan located on a gas transverse outer side of the engine and capable of blowing outside air to the side of the engine;

An engine bonnet configured to divide the driving unit and the engine up and down to form an engine room, and to accommodate the engine and the blowing fan;

The said engine room is located in the back side of the said engine, and the guide member which guides the wind from the said blowing fan toward a downward side is provided.

According to this structure, among the warm air after engine cooling, especially the warm air which entered the back side of the engine, it guides toward the downward side by a guide member. Therefore, it becomes difficult to inject warm air into an engine bonnet, and it can reduce that an engine bonnet becomes warm by warm air. As a result, the driver feels hot, and the combine is a comfortable driving environment.

According to the present invention,

It is suitable that the said guide member is comprised so that the wind from the said blowing fan may block the back side.

In this configuration, since the diffusion to the rear side of the warm air is reduced, a larger amount of warm air is guided downward by the guide member. That is, with this structure, it becomes a guide member which can control the direction of a warm air efficiently.

According to the present invention,

The said guide member is suitable if it is provided in the frame member which supports the said engine bonnet.

According to this structure, since the frame member which supports an engine bonnet is also used for the member which installs a guide member, compared with the case where the exclusive member which mounts a guide member is provided, the number of parts is restrained. That is, with this structure, even if the guide member is provided, the structure in the engine bonnet does not become complicated, so the influence on the arrangement of the other members around the guide member is small, and the manufacturing cost is also kept low.

According to the present invention,

The guide member is preferably provided with an inclined portion having a posture downwardly opposite to the blower fan as it is spaced apart from the blower fan in the gas left and right directions.

According to this structure, since the inclination part becomes downward on the opposite side to a blowing fan as it is spaced apart from a blowing fan in the gas left-right direction, the warm air which touches an inclination part is guided downward along a inclination part. That is, with this structure, a warm structure can be guided to the downward side by the simple structure of providing inclination part.

According to the present invention,

It is suitable that the guide member is provided with a shield having a posture along the gas left and right direction and a posture along the gas up and down direction.

According to this structure, since the shielding part is a posture along the gas left-right direction and the gas up-down direction, the warm air is certainly received by the shielding part, the amount of warm air diffused to the rear side is reduced, and a larger amount of warm air is applied to the guide member. It is guided to the lower side efficiently by this.

According to the present invention,

The guide member is provided with an inclined portion of a posture downwardly opposite to the blower fan in the horizontal direction of the gas as opposed to the blowing fan, and a shielding portion of a posture along the left and right directions of the body and an up and down direction of the body,

The shielding portion is preferably provided adjacent to the rear portion of the inclined portion.

According to this configuration, since the shielding portion is adjacent to the inclined portion, there is no gap in which the warm air is to be diffused therebetween, so that a larger amount of warm air can be efficiently guided downward.

According to the present invention,

The guide member is provided with an inclined portion of a posture downwardly opposite to the blower fan in the horizontal direction of the gas as opposed to the blowing fan, and a shielding portion of a posture along the left and right directions of the body and an up and down direction of the body,

The said guide member is suitable if it is comprised so that the lower end part of the said shield part may be located below the lower end part of the said inclination part.

According to this structure, the lower end of a shield is located below the lower end of a slope. That is, since the shield is configured to be as large as possible, the warm air is widely accepted by the shield. Therefore, diffusion to the rear of the warm air is effectively prevented. As a result, the amount of warm air guided downward is increased, and the engine bonnet is further prevented from becoming hot.

According to the present invention,

A vent hole is provided on the side opposite to the blower fan by inserting the engine,

The guide member is suitable if the wind from the blower fan is guided to the side of the tuyere.

According to this configuration, since the warm air is guided to the side of the tuyere by the guide member, the temperature of the sorting wind from the tuyere is increased. As a result, the sorting wind by the tuyere does not play a role as a dryer, and the grain etc. which are sorting objects are dried, and sorting performance improves. Thus, with this structure, in addition to the improvement of a driving environment, the improvement of the sorting ability of a combine can be implement | achieved by control of the wind direction of a warm wind.

According to the present invention,

The guide member is provided with an inclined portion having a posture downwardly opposite to the blower fan as it is spaced apart from the blower fan in a gas left and right direction,

It is suitable if the vertical part of the posture along a gas up-down direction is provided continuously in the upper end of the said inclination part.

The inclined portion has a wider area with respect to the warm air and receives the warm air widely, and can be guided downward more reliably. And as long as the inclination part is inclined shape, in order to make inclination part large, the space of the gas left-right direction is needed widely. However, in the engine room, an engine auxiliary machine etc. are arrange | positioned other than an engine, and there may be a restriction in the installation space of a slope part.

According to this structure, the warm air which tries to pass upward of the inclined part is guided to the inclined part somewhat by the vertical part, and the amount of the warm air guided downward is increased compared with the case where it is not provided with the vertical part. That is, when configured as in this configuration, since the vertical portion does not require a space in the left and right directions of the gas, even if a large inclined portion is not provided in the engine room, the amount of warm air guided downward by the inclined portion can be increased. Do.

According to the present invention,

The guide member is preferably provided so as to be located on the rear side of the upper portion of the engine.

Since warm air rises, the warm air after cooling of an engine or the like tends to rise. However, according to this structure, since the guide member is arrange | positioned at the rear side of the upper part of an engine, more warm air can be guided below by a guide member.

According to the present invention,

The said guide member is suitable if it is provided so that it may be located in the back side vicinity of the center part in the gas left-right direction of the said engine.

Since the wind speed of the blower fan is weaker as it is separated from the blower fan, if it is not controlled at the earliest possible stage, the wind speed spreads in various directions, and if the wind speed is low, the guide member may not be able to guide downward. have. On the other hand, if the wind by the blower fan is guided downward at a too early stage, there is a fear that the engine cannot be cooled sufficiently.

According to this structure, since the guide member is arrange | positioned in the back side near the center part in the gas left-right direction of an engine, the warm air after completion of cooling of an engine to some extent can be guided to the downward side before a wind speed falls.

According to the present invention,

The driving unit is exposed to the outside,

A grain tank is provided at the rear side of the driving unit and the engine,

The rear side of the engine room is suitable if it is open to the side of the grain tank.

If the combine is configured as described above, if the direction of the warm air is not controlled, the warm air escapes from the engine room to the rear side, rises between the driving unit and the grain tank, and reaches the driving unit. However, even with such a combine, if the guide member is provided, it is difficult for hot air to reach the driving unit, and thus it is possible to keep the driving environment comfortable.
