During the intake of cooling air by the fan, the intake pressure
Dust adsorbs on the perforated plate of the intake port formed in the zinc cover
As a result, the cooling air intake efficiency is reduced and
There is a disadvantage that the gin tends to overheat.

[0009]

According to the present invention, there is provided the present invention as described above.
Take the following technical measures to resolve the issues:
You. That is, the engine E and the engine E mounted on one front side of the vehicle body 1
An intake port 15 is installed in the engine cover 2 that covers the radiator and radiator.
Only, on the engine cover -2 air cleaner 3 of the engine E, the oil tank 4 of the hydraulic stepless transmission, and by arranging the air-conditioning unit 5, the provided unit cover 6 covering these, the unit cover 6 on the front side of the indoor air inlet 9 provided on the cockpit 8 rear portion of the cabin 7, also in the upper portion of the unit cover 6 is provided with a duct 10 for air supply to the ceiling portion of the cabin 7, and, The unit cover-6
Also, an intake port 16 is provided so that when the engine E is driven,
The outside air is united by the
It is sucked into the cover 6 and further passes through the unit cover 6.
It is configured to flow through the air port 25 and into the engine cover-2.
The driving portion of the cabin with a combine you, characterized in that the form was
Ru der those with the structure.

When the engine E is driven, the intake air is sent from the air cleaner 3 to the carburetor of the engine E in the unit cover 6 on the engine cover 2 .
When the vehicle is driven by the hydraulic continuously variable transmission, the oil for hydraulic pressure is supplied from the oil tank 4 and the oil to be heated is cooled.

In the unit cover 6, a heat exchanger, a blower, and the like serving as the air conditioning unit 5 operate to draw indoor air from the cabin 7 through an indoor air inlet 9 at a rear portion of the cockpit 8, and to perform a duct operation. Circulation is supplied from the ceiling to the room through 10. As described above, since the indoor intake port 9 to be sucked into the air conditioning unit 5 is provided on the rear side of the cockpit 8 of the cabin 7, the air flow around the cockpit 8 is good, and the air conditioning is further improved. Unit 5 is provided in the unit cover 6 together with the air cleaner 3 and the oil tank 4 and the like, and the duct 10 of the cabin 7 can be connected to the air conditioning unit 5. When the unit 5 and the like are attached and detached, the air conditioning unit 5 can be attached and detached between the cockpit 8 and the engine cover 2 or the unit cover 6. 7 side and not good if connected.

When the engine E is driven, the radiator
The outside air is drawn into the unit
Inhaled into bar 6 and further ventilated from inside unit cover 6
It flows through the mouth 25 into the engine cover-2. others
The oil tank 4 in the unit cover 6 and the air conditioning unit
In addition to promoting heat dissipation from the knit 5, the engine cover

can do.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION The combine vehicle body 1 has a pair of left and right crawlers 11 at the bottom, and a cockpit 8 and a cockpit are provided on the front right side in the traveling direction, and the cabin 7 is covered so as to cover these. Mount. The engine E covered by the engine cover 2 is mounted below the cockpit 8 and the Glen tank 12 is mounted on the rear side to accommodate grains to be threshed. 13
Is a grain discharging auger, which can take out and transport grains stored in the Glen tank 12 in any direction.

A reaper 14 is provided at the front of the vehicle body 1,
On the left side of the vehicle body 1, a threshing device is mounted,
After the culm is transported by the feed chain, the spikes are supplied to the threshing chamber and threshed while being transported by the feed chain. The engine cover 2 has an intake port 15 formed by a perforated plate or the like on the right side surface, and a driver's seat 8 is located in the front half of the engine cover 2. Also, a unit cover 6 is provided in the rear half. The unit cover 6 has, on the left side thereof, an intake cover (intake port) 16 made of a metal plate or the like which can be opened and closed, and has an indoor intake port 9 on the front side facing the back of the cockpit, and an upper side on the upper side. It has a duct port 17. The air inlet 9 has an air filter.

An air cleaner 3 for supplying air to the carburetor of the engine E is provided below the unit cover 6, and an oil tank 4 for a hydraulic continuously variable transmission mainly for driving and transmitting the traveling crawler 11 is provided. I have. Reference numeral 18 denotes a lubrication port of the oil tank 4, which can be lubricated by opening the intake cover 16. Reference numeral 19 denotes a liquefied gas tank for dehumidifying an air conditioner.

An air conditioner unit such as a heat exchanger 21, an air blower 22, and an air filter 27 for an air conditioner is formed at the upper portion of the unit room, which is partitioned by a perforated plate 20 or a blind plate. 5 for pipe communication with a compressor or the like driven by the engine E in the lower engine cover 2 or the like.

The cabin 7 is provided with an openable / closable door 23 mainly made of glass on the left side, and the right side and the front and rear sides can be seen through as glass windows. The bottom of this cabin 7 is open, and by mounting it on the vehicle body 1 of the combine,
Since the bottom is surrounded by the front part of the unit cover 6, the seat floor part such as the front part from the top surface of the engine cover 2, the step floor part, the flight deck part, etc. It is made airtight by a sealing material or the like.

A duct 10 is provided on the ceiling of the cabin 7 so that air can be supplied into the cabin 7. This duct 10
The rear end can be connected to the duct port 17 via the connection duct 26 located above the unit cover 6 in the mounting posture of the cabin 7, and from the heat exchanger 21 of the air conditioner through the duct 10 through the duct 10. Can be sent to The rear ceiling of the cabin 7 has a rear window 24 that can be opened and closed upward.

A vent 25 is provided between the engine cover 2 and the upper unit cover 6. The air-conditioning unit 5 has an outer periphery covered by a case 33, a bracket 29 having pins 28 attached to both left and right sides thereof, and a hook 28 provided on a ceiling portion of the unit cover 6.
Can be detachably hung by engaging. Reference numeral 31 denotes a fixing stay, which can fix a part of the suspended air conditioning unit 5 to a part of the unit cover 6 by tightening a bolt 32. A filter 27 is provided on one side of the case 33 on the side of the intake cover 16 at an extension of the perforated plate 20, and the outside air sucked from the intake cover 16 into the unit cover 6 is supplied to the air filter 27. Is sucked into the blower 22 through the In addition, the indoor air sucked from the air inlet 9 passes directly between the outer periphery of the case 33 and the perforated plate 20 into the blower 22. Reference numeral 34 denotes an intake cover provided on the rear side surface of the unit cover 6. A duct cover 35 covers the connection duct 26.

When the engine E is driven, the radiator and the engine E are cooled by the intake air of the radiator fan and the outside air taken in from the intake port 15. At this time, a part of the outside air is sucked from the intake cover 16 of the upper unit cover 6 and flows into the engine cover 2 from the inside of the unit cover 6 through the vent 25. For this reason, the intake area of the radiator is large due to the upper and lower intake covers 16 and the intake ports 15 and the like, and the intake pressure at these intake ports is reduced to reduce the intake and adsorption of dust. Can be.

When the air conditioner is operated, the air is sucked from the air inlet cover 16 and the indoor air inlet 9 by the drive of the blower 22, once passes through the filter 27 and enters the air conditioning unit 5, and is adjusted by the heat exchanger 21. Air flows into duct port 17
From the cabin 7 through the connecting duct 26 and the duct 10
Sent inside. The inside air in the cabin 7 is again sucked into the indoor intake port 9 behind the cockpit 8 and circulated.
