Japanese Patent Application Laid-Open No. 2010-223325 Japanese Patent Application Laid-Open No. 2010-166865

In the combine having the cabin, a condenser for radiating the coolant of the air conditioner for air conditioning and an oil cooler for cooling the hydraulic oil of the hydraulic system are disposed in the vicinity of the radiator, so that the air sucked through the dust- .

In consideration of the cooling performance of the radiator, it is not desirable to arrange the condenser at a position covering the entire surface of the heat exchange surface of the radiator, and it is desired to arrange the condenser in a reasonable manner.

An object of the present invention is to provide a combine for cooling a condenser without lowering the cooling performance of the radiator.

In the above-described configuration, the air supply output from the air conditioner is jetted from the jet port into the cabin, so that the inside of the cabin can be kept in a comfortable state and a good harvesting operation can be performed. As the air supply output from the air conditioner, for example, in summer, air having a lower temperature than the outside air is blown into the cabin.

However, in the above-described conventional structure, the air outlet of the air supply formed at the front side portion is located near the central portion in the lateral direction of the vehicle, and the air supply is discharged toward the downside of the rear portion. Further, The air conditioner is installed at a position lower or rear than the air conditioner, so that the air conditioner is installed at a position nearer to the driver. As a result, there is a possibility that the air supply jetted out from the air outlet is blurred toward the driver, which may cause the driver to feel uncomfortable.

SUMMARY OF THE INVENTION An object of the present invention is to provide a combine capable of making it possible to perform a harvesting operation in a comfortable state with less possibility of a driver feeling discomfort in a cabin.

A feature of the present invention is a combine comprising a radiator fan and a radiator disposed outside a base of an engine provided in a traveling vehicle and a vibration damping network of a dustproof case for supplying cooling air to the radiator at a position outside the base of the radiator,

And the air conditioning condenser is arranged in a position in parallel with the upper part of the outside of the radiator in the gas width direction inside the dustproof case.

According to this configuration, since the condenser is disposed in the upper part of the outer side of the radiator so as to be parallel to the gas width direction, the air heated by the condenser is sent to the upper part of the radiator, The problem of being sent to the entire surface is suppressed. Further, in the combine, since the air conditioner device is disposed above the dustproof case such as the cabin, the piping for circulating the heating medium between the air conditioner and the condenser can be shortened.

Therefore, a combine capable of cooling the condenser is formed without lowering the cooling performance of the radiator.

In the present invention, an oil cooler may be disposed on the outer side of the radiator within the dustproof case and below the condenser.

For example, in a configuration in which the condenser and the oil cooler are disposed in a positional relationship in which the oil cooler is entirely overlapped, the cooling air supplied to the radiator passes through the condenser and the oil cooler to obstruct the flow of the cooling air. It is possible to directly supply the cooling air that has passed through the condenser to the radiator and also supply the cooling air that has passed through the oil cooler directly to the radiator so that the cooling air is flowed well to prevent cooling of the radiator .

The present invention may include an electric fan between the radiator and the condenser.

According to this, even when the electric fan is driven in the intake direction, even if the electric fan is driven in the exhaust direction, air is supplied to the condenser to achieve good heat exchange. Particularly, when the electric fan is driven in the exhaust direction, it becomes possible to blow straw or dust attached to the vibration damping net of the dustproof case by wind pressure.

In the present invention, the dustproof case may be configured to be openable and closable, and the electric fan may be supported by the dustproof case.

According to this, when the dustproof case is opened, the electric fan is moved together with the dustproof case, and the vicinity of the radiator is largely opened, so that the maintenance of the radiator, the electric fan, and the like can be easily performed.

The present invention may be provided with fan control means for driving the electric fan in a direction for discharging the air inside the dustproof casing to the outside of the casing at the time of operation of the unloader provided in the running vehicle.

According to this, when the unloader is operated, the fan control means drives the electric fan in the direction of discharging the air inside the dustproof case to the outside of the casing, and the dust of the straw or the like attached to the outer surface of the vibration- To keep the cooling performance high.

The combine according to the present invention is characterized in that the air conditioner is provided in a front portion of a ceiling portion of a cabin that covers an operation portion and a jet port for jetting an air supply supplied from the air conditioning device through the duct into the cabin, And the first feature of the present invention is that the front side air outlet formed at the front side portion is formed in a state of being positioned outside the gas width direction of the air conditioner .

According to the first aspect of the present invention, the front side air outlet is formed in a state of being located on the outside in the gas width direction of the air conditioner. The air conditioner is provided in the front portion of the ceiling portion of the cabin. Further, since the air conditioner is a large apparatus, it occupies a predetermined width along the width direction of the base. In other words, the front side air outlet located at the outside of the air conditioner in the air conditioner in the air conditioner is located at a position close to the gas widthwise direction end portion of the ceiling portion, in other words, from the driving seat located at the center of the cabin in the vehicle width direction, As shown in FIG.

Further, since the front side air outlet is formed in a state of being positioned outside the gas width direction of the air conditioner, it is possible to narrow the duct arrangement area at the rear side portion of the air conditioner along the gas front and rear direction, It is possible to enlarge the inner space on the upper side of the front side.

Therefore, the air supply output from the air conditioner and supplied through the duct and ejected from the front-side air outlet becomes less likely to be sprayed toward the driver, and furthermore, the inner space above the driver can be widened, It is possible to provide a combine capable of making a harvest operation in a pleasant state with less concern that the driver who is driving in the farm is less likely to feel discomfort.

A second aspect of the present invention resides in that a duct for supplying an air supply discharged from the air supply outlet of the air conditioning apparatus toward the rear of the gas supply is provided in a state of extending toward the gas widthwise direction.

According to the second aspect of the invention, the air supply is discharged from the air supply outlet of the air conditioner toward the rear of the air supply unit. However, the air supply unit is arranged such that the air supply unit directs the air supply discharged from the air conditioning unit to the front side air outlet The supply air is suddenly discharged from the air supply outlet of the air conditioner and the air supply is once taken from the inner wall surface on the gas rear side of the duct and the flow rate is lowered even if the flow rate near the air supply outlet is large, The flow rate is lowered in the vicinity of the jet port on the front side.

Therefore, when the air is discharged from the front side air outlet, the flow rate of the air supply becomes low and it is possible to avoid the air supply being blown toward the driver in a burst.

The duct according to the third aspect of the present invention is characterized in that the duct includes a front side duct portion for supplying the air supply to the front side air outlet and a rear side air duct portion for supplying the air supply to the lateral air outlet formed at the lateral side portion, It is in point that it is.

According to the third aspect, the supply air discharged from the air supply outlet of the air conditioner is supplied to the front side air outlet through the front side duct portion of the duct and supplied to the lateral air outlet through the rear side duct portion of the duct . Since the duct is branched into the front duct portion and the rear duct portion as described above, it is possible to separately provide the ducts on the front side and the rear side for supplying the air to the front side air outlet and the lateral air outlet, respectively The installation space can be reduced and the configuration can be simplified.

The fourth feature of the present invention resides in that the front-side air outlet is formed in a state in which the air outlet is located closer to the gas front side than the gas rear side end of the air conditioner.

According to the fourth aspect of the present invention, it is possible to effectively use the portion located on the gas front side of the air conditioner than the gas rear side end portion of the air conditioner and on the outside side in the gas width direction of the air conditioner, It is not necessary to form a space for arranging the ducts in the front-back direction on the back side of the base.

In other words, since the duct space for arranging the ducts in the forward and backward directions is unnecessary at the rear side of the air conditioner than in the air conditioner, the internal space above the driver can be widened and the driver can enjoy a more comfortable state The harvesting operation can be performed.

A radiator fan 53 driven by an endless belt to which the driving force of the engine E is transmitted is disposed between the radiator 52 and the engine E. The radiator fan 53 is disposed at a position surrounding the outer periphery of the radiator fan 53 and the shroud 54 And the shroud 54 is supported by a radiator 52. The shroud 54 is supported by a radiator 52, A condenser 55 is arranged in parallel with the upper portion of the radiator in the gas width direction at an upper position on the outer side of the base with reference to the radiator 52. Between the condenser 55 and the radiator 52, The electric fan 56 is rotated by the driving force of the electric motor 56M.

An oil cooler 57 is disposed below the condenser 55 in parallel with the lower portion of the radiator 52 in the gas width direction. The oil cooler 57 is disposed closer to the radiator 52 than the condenser 55 Position. The condenser 55 and the oil cooler 57 are substantially equal in size to each other in the vertical direction and the condenser 55 is arranged in parallel in the region of approximately half the upper side of the radiator 52 when viewed from the side, The cooler 57 is arranged in parallel and a part of the lower part of the condenser 55 and the upper part of the oil cooler 57 are disposed at the overlapping positions when viewed from the side.

Particularly, by arranging the oil cooler 57 in a space below the condenser 55, it is possible to arrange the oil cooler 57 at a position where the condenser 55 and the oil cooler 57 overlap each other in a plan view. The protruding amount of the condenser 55 and the oil cooler 57 to the outside of the casing can be made small and the dustproof casing 13 can be made compact.

The condenser 55 is connected to the air conditioning system 29 by the heating medium pipe 58 so as to radiate heat of the heating medium supplied from the air conditioning apparatus 29. The oil cooler 57 is connected to the above- And is connected to the flow path system by an oil pipe 59 so as to cool the used oil.

The condenser 55 is supported on the inner surface of the dustproof casing 13 by the upper bracket 55A and the electric fan 56 is supported by the dustproof casing 13 And the oil cooler 57 is supported on the inner surface of the dustproof casing 13 by the lower bracket 57A.

The control system is set so that electric power is supplied to the electric motor 56M of the electric fan 56 when the control device 62 determines that the discharge clutch lever 21 has been operated to the on position . The vibration suppression control system is provided with a sensor for detecting the operation of the unloader 6 such as a rotation sensor for determining that the bottom screw 5S has rotated and detecting the operation of the unloader 6 by the sensor In this case, the electric fan 56 may be driven.

The radiator fan 53 is set in such a manner that the operating direction is set such that it always rotates in the direction of sucking the cooling air during the operation of the engine E (see Fig. 5), and the electric fan 56 is not driven The upper cooling air sucked into the dustproof casing 13 through the dustproof net 14 passes through the condenser 55 and the electric fan 56 and is supplied to the upper portion of the radiator 52. [ The lower cooling air sucked into the dustproof case 13 passes through the oil cooler 57 and is supplied to the lower portion of the radiator 52. [ Thereby, the cooling wind is supplied to the condenser 55, the oil cooler 57, and the radiator 52, and these cooling can be satisfactorily performed.

When the discharge clutch lever 21 is operated to the ON position and the unloader 6 is operated, this operation is detected by the discharge lever sensor 61 and the control device 62 operates the electric fan 56 The air inside the dustproof casing 13 is sent to the outside of the casing against the flow of the air by the intake air of the radiator fan 53. [ As a result, the air to be sent to the outside of the casing passes through the condenser 55 and is sent to the outside of the casing from the casing 14 to blow the dust of the straw or the like attached to the outer surface of the casing 14 with wind pressure, 14). When the unloader 6 operates to operate the electric fan 56 at the time of operation of the unloader 6, a large amount of dust is generated. When the unloader 6 is operated, It is possible to satisfactorily suppress the problem that the generated dust adheres to the dust-proofing net 14.

Particularly, since the condenser 55 is arranged in parallel on the outer side of the radiator 52, the problem that the air heated by the condenser 55 is sent to the entire surface of the cooling surface of the radiator 52 is prevented. Since the air conditioner 29 is disposed on the upper portion of the cabin C as compared with the case where the condenser 55 is disposed below the radiator 52, the air conditioner 29 is disposed between the air conditioner 29 and the condenser 55 The length of the heat medium pipe 58 is also reduced.

In this combine, since the hydraulic device for sending the oil to the oil cooler 57 is disposed below the traveling base 2, for example, compared with the arrangement of the oil cooler 57 on the upper portion of the radiator 52 The reduction of the length of the oil piping 59 is also realized.
