。With the conventional technology described in 1-1, there is no problem if you purchase four passenger IL aircraft that have an air-conditioned cabin from the beginning. Even if you purchase a passenger agricultural machine and later request to modify the cabin to include an air conditioner, the front and rear struts of the large cabin or safety frame will not allow the passage of high-pressure pipes and low-pressure pipes. Since it had a thick hollow part, it could meet such requests for modification, but there was a problem that the same method could not be used for small cabins or safety frames.
この発明は、上記問題点を解決するためにつぎの技術的

柱の内側に沿わて配管した構成とした。This invention has taken the following technical means to solve the above problems. That is, in the cabin of a riding agricultural machine, which is installed in the vehicle body to ensure an operating space during cold operation, the air conditioner unit is installed in the ceiling frame that connects one end of the front column and one end of the rear column of the cabin. A high-pressure pipe and a low-pressure pipe communicating with the air conditioner unit 1- are installed along the inside of the left rear strut.

ンユニツ１−の上を屋根で被い、改造を完了する。When you are working on a riding agricultural machine and the cabin gets hot and you need cool air, switch the air conditioner switch from the ventilation position to the cooling position, the compressor will operate, and the refrigerant gas will exchange heat with the air conditioner unit via high pressure pipes. The outside air that is sucked in by the air conditioner unit is cooled as it passes through the heat exchanger, and is then blown out into the cabin as cold air. When converting a cabin without a safety frame or air conditioner into a cabin with air conditioner, remove the roof and install the air conditioner unit on the ceiling frame, and also run the high pressure pipes and low pressure pipes of the air conditioner unit 1- along the ceiling frame. At the same time, pipes are installed along the rear column on the left side of the cabin, the other ends of the high-pressure pipe and the low-pressure pipe are connected to the compressor side provided in the vehicle body, and the top of the air conditioner unit 1- is covered with a roof. Complete the remodel.

コン付きのキャビンに容易に改造することができる。This invention provides an air conditioner unit installed in a ceiling frame that connects the upper end of the front strut and the upper end of the rear strut of the cabin of a passenger agricultural machine, which is installed in the vehicle body in order to secure an operating space near the driver's seat door. After installation, the high-pressure pipe and low-pressure pipe that communicate with this air conditioner unit were routed along the inside of the above-mentioned rear column on the left side, so the driver operated the lift lever on the right side to activate the ref l-device. The rear view is not obstructed when moving the riding agricultural machine backwards while raising and lowering the rear working machine, or when checking the status of the working machine.
Also, a cabin without a safety frame or air conditioner can be easily converted into a cabin with air conditioner.

Both left and right ends of the rear wall 14, which is provided between the tank 13 and the fuel tank 13 so that its upper side is higher than the fuel tank 13, are attached to the fenders 11, 11, and a rear window is provided along the "-" side of the rear wall 14. The left and right sides of the frame 15 are attached along the back of the fender 11° 11, and the left and right ends are fixed to the inner lower ends of the rear struts 4, 4, and between the left rear strut 4 and the rear window 7,
The damper 16 that adjusts the opening degree of the rear window 7 is
1- A cover 17 is provided with the lower end pivotally attached, and a cover 17 that protrudes inward by the diameter of the damper 16 is provided on the inside of this left rear column 4 and is then removably attached along the column 4.
The lower part of 7 is detachably attached so that it is once bent forward from the left end of the rear window frame 15 and then communicated with the lower exterior of the lower floor 18. A sloped portion is formed on the surface. The ceiling frame 20 of the ceiling 5 attached to the upper ends of the front columns 3, 3 and the rear columns 4, 4 frames the front frame 21, left and right side frames 22, 22, and rear frame 23 in a rectangular shape, and has a front frame in the middle. 21 and the rear frame 23 are connected by vertical frames 24, 24, and the vertical frames 24, 24 are connected to the horizontal bars 25, 2.
5, and the side frames 22, 22 and vertical frames 24, 24 are connected by horizontal rods 26, 26. A ceiling member 27 is attached to the lower side of this ceiling frame 21 to form a ceiling 5. An air conditioner unit 28 is installed between the vertical frames 24, 24 of the ceiling 5, and a high pressure inlet portion on the right side of this air conditioner unit 28 is installed. 29, a low pressure pipe 32 is connected to the low pressure outlet 31, the high pressure pipe 30 and the low pressure pipe 32 are passed through the cover 17, and the high pressure pipe 30 is passed under the floor 18. is connected to a discharge portion of a compressor 33 installed on the engine (not shown) side. Further, the low pressure pipe 32 is connected in series to the suction portion of the compressor 33 via a filter 34 and a condenser 35 provided near a radiator (not shown). In addition, the air conditioner unit 28 is configured to discharge indoor air to the outside, and inhale outside air to be blown into the cabin 2 through a heat exchanger (not shown). In the cooling position, air flows between the outside and the interior of the cabin 2, and in the cooling position, the compressor 33 is operated to send refrigerant gas to the heat exchanger.6 Furthermore, water droplets generated in the heat exchanger are It is configured to be discharged to the outside via connected drains 36... The compressor 33 is covered by a roof 6 attached to the top of the ceiling frame 20. The ceiling 5 and roof 6 are shared by the cabin without air conditioning and the safety frame. 3
7 is a heating device installed in front of the ceiling frame 20, 38 is a roof 6

却され、キャビンの中い冷気が噴出される。Next, the effect will be explained. When you are working on a farm on a tractor, the inside of the cabin 2 becomes hot and you need cool air. When you switch the air conditioner switch from the ventilation position to the cooling position, the compressor 33 is activated and the refrigerant gas flows through the high-pressure pipe 30. The outside air is then force-fed to the heat exchange section of the air conditioner unit 28 through the air conditioner unit 28, and the outside air sucked in by the air conditioner unit 1-28 is cooled as it passes through the heat exchange section and is blown out into the cabin 2 as cold air. Then, the refrigerant gas that has absorbed heat in the 1-recording heat exchange section passes through the low-pressure pipe 31 and leaks through the filter 34 in the middle, and also flows into the condenser 3.
5, the heat is radiated and returned to the compressor 33. When the air conditioner switch is set to the cooling position as described above, the outside air is cooled by the heat exchange section of the air conditioner unit 28, and the cool air inside the cabin is blown out.

The lower part of the air conditioner unit 28 is attached removably so that the lower part of the air conditioner unit 7 is bent forward from the left end of the rear window frame 15 and communicates with the lower part of the floor 18 below. Since the low-pressure pipe 32 is configured to pass through the cover 17, the width of the cover 17 may be about the diameter of the damper 16 of the rear window 7, and even the cabin 2 of a small tractor can be used for agricultural work. The time is.
