DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a simplified air conditioner for a combine.

[0002]

2. Description of the Related Art Conventionally, moving vehicles such as agricultural work machines, civil engineering works, and construction work machines are equipped with a cabin on which a pilot sits on a vehicle body. The configuration has been devised to raise The air conditioner is installed on the ceiling of the cabin, and a grill that blows air (heat / cold air) from the air conditioner into the cabin room is opened above the pilot's head. The drain hose of the drainage generated by condensing the water inside is constructed by piping from the ceiling to the rear of the cabin. Further, the air conditioner was configured to be provided near the engine room.

[0003]

The above-mentioned conventional structure is provided with a full-scale cabin-type combine equipped with an air conditioner, and the cabin is kept at a comfortable temperature by being shut off from the outside. Work efficiency. However, this conventional type inevitably has a problem that the traveling body becomes large, the manufacturing cost is increased, and it is not suitable for a lightweight, compact and widespread combine. Further, since the air conditioner was provided near the engine room, the air conditioner was contaminated with dust and the like, so that the maintenance management had to be constantly performed.

[0004]

The present invention takes the following technical means in order to solve the above-mentioned conventional problems. That is, in a combine where the steering seat 4 is mounted on the traveling vehicle body 2 and the Glen tank 23 is provided behind the steering seat 4, the air conditioner 5
The blast grille 6 is provided so as to blow out the temperature-changed air (hot air / cold air / air blast) blown from the air conditioner 5 above the control seat 4. And air conditioning equipment 5
Is a simplified air conditioner of a combine which is configured to be provided on the Glen tank 23.

[0005]

Since the present invention is constructed as described above, the air (heat / cold air) adjusted by the air conditioner 5 is sent to the upper part of the control seat 4 through the blower duct 7 and the blower grill 6. Can be. Therefore, the present invention solves the problems of the conventional type, and is lightweight and small (spread type) with reduced manufacturing cost.
A combine having a simple air-conditioning effect can be provided. Further, since the air conditioner 5 is provided above the Glen tank 23, it is relatively rarely exposed to dust and the like, and therefore, the maintenance management cycle is shortened, and the burden on the operator can be reduced.

[0006]

Embodiments of the present invention will be specifically described below. The combine has a threshing device 1 mounted on a vehicle body 2 having a crawler 8 and a cutting pretreatment device 3 in front of the threshing device.
Is provided to enable mowing and threshing work. As is conventionally known, the threshing apparatus 1 is provided with a handling chamber with a handling cylinder mounted on the upper side and provided on the upper side, and a rocking sorting apparatus and a sorting chamber having a pressurized karamin on the lower side. It is composed. The pre-cutting device 3 is provided with a weeding rod 9 at the front low position, a grain stem raising device 10 at the rear thereof, a cutting device 11 at a low position behind the same, and threshing the harvested grain culm. A cereal culm conveying device 12 for conveying to the device 1 is provided and configured.

[0007] As shown in FIGS. 2 and 3, the cockpit 4 is provided at the side of the pre-cutting device 3 with the threshing device 1.
And an operation lever and operation panels (operation switches) for operating the traveling vehicle body 2 and each work machine (threshing machine 1 and pre-cutting device 3) are provided in a concentrated manner. Next, the air conditioner 5 is installed above the Glen tank 23, and is configured to blow out the adjusted air (heat / cold air) to the air duct 7 and send it upward. Further, the air conditioner 5 is not disposed on the machine frame 14 that forms the outer frame of the engine room 13. A gas pipe and a hot water pipe attached to the air conditioner 5 are piped along the Glen tank 23 and the machine body, and the gas pipe is connected to a condenser 15 mounted on the upper part of the threshing apparatus 1, and the hot water pipe is connected to the lower part. The structure communicates with the engine side, with the former used for cooling and the latter used for heating.

The blast grille 6 is mounted on the upper part of the air duct 7 as shown in FIGS.
An opening is provided so as to blow forward from above and behind the operator sitting in the air duct, so that air (hot / cold air) flowing in the blower duct 7 can be blown to the operator side. . In this case, the blast grille 6 blows the right side to the operator and the left side to the left side of the operator in the forward direction of the traveling vehicle body 2 as shown in FIG. The dust generated from the grain stalks during transportation of the vehicle is arranged to flow away from the control seat 4.
In addition, when the blast grille 6 on the left side is used only for dust removal, do not use the adjusted air (heat / cold air).
It is configured so that it can be configured to blow normal air (blowing).

Next, as shown in FIG. 4, the filter 16 of the air conditioner 5 has dustproof nets 17, 1 on the outside and the inside.
7 'is stretched and sandwiched between them to form a triple structure. The outer dustproof net 17 is formed on the same plane as the side of the machine frame 14. Reference numeral 18 denotes a support arm. Sun visor-19 covering the upper part of the worker
As shown in FIGS. 1 and 2, a cloth is stretched around the surrounding frame material to form a ceiling portion, and both sides of the rear portion are freely bent to support rods 20 and 20 'by tightening screws as shown in FIG. The lower part of the supporting rods 20 and 20 ′ is attached to an attaching machine frame 21 by screws 22 so as to be foldable.
In this case, the sun visor 19 exerts not only the function of blocking the original rain and the direct rays, but also the function of keeping the adjusted air blown out from the blast grille 6 as far as possible upward. The sun visor 19 may or may not be installed according to the preference of the operator.

Next, the operation will be described. First, in the combine work, the operator sits on the cockpit 4 and starts the engine to prepare for the harvesting and threshing work.
At the same time, the user operates the dial on the operation panel to set the temperature of the air conditioner 5 and then starts the operation. Then, the air conditioner 5 starts the air conditioning operation based on the equipped control mechanism, and uses the chlorofluorocarbon gas and the hot water circulated through the gas pipe and the hot water pipe to perform the air conditioning action by cooling and heating. It starts.

As described above, the air conditioner 5 blows out the air (heat / cold air) kept at the set temperature into the blower duct 7 and blows out from the blower grill 6 at the distal end toward the operator. Therefore, the air around the upper part of the control seat 4 is subjected to a simple air-conditioning operation by adjusting air having a set temperature flowing out so as to cover the upper body of the operator. At that time, the sun visor 19 plays a role of protecting the operator by blocking the direct rays of light, and furthermore, preventing the conditioned air blown out from escaping upward as described above as much as possible, thereby enhancing the air conditioning effect.

In the case of the embodiment, since the air conditioner 5 is mounted on the upper portion of the Glen tank 23, the air conditioner 5 is located at a high position, sucks clean air with relatively little dust, and uses the air for air conditioning. Can be. Further, the filter 16 for filtering air to the air conditioner 5 has dustproof nets 17 and 17 'stretched in a sandwich shape before and after in the direction of sucking outside air, and therefore does not suck dust.

When the combine is advanced in the above-described state, the culm in the field is cut off by the pre-cutting device 3 and then transported rearward and upward to be supplied to the threshing machine 1 for threshing. The operator is protected by a simple air-conditioning device 5 in which the air is sent by the simple air conditioner 5 even in the hot summer season and, conversely, in the cold autumn season, so that the harvesting and threshing operation can be performed relatively easily.

Next, FIGS. 5 and 6 will be described. In the above-described configuration, the air conditioner 5 is provided above the Glen tank 23. However, the air conditioner 5 may be provided above the threshing machine 1 similarly to the condenser 15 because of its relatively high position. In this case, as shown in FIG. 6, since the positional relationship between the air conditioner 5 and the blast grille 6 is shifted in the lateral direction of the combine, the blower duct 7 is inclined, but there is no problem in performance. When the blower duct 7 is formed of a bellows or the like, assembly and maintenance can be easily performed.

Next, FIG. 7 will be described. Air conditioning equipment 5
In providing the inner space 24a of the operation post 24,
It is set to be installed in Conventionally, nothing is provided in this place, so that the internal space 24a is used effectively. Further, since the internal space 24a is a closed space despite being below the combine, there is relatively little dust. Therefore, there is no problem even if the air conditioner 5 is installed. Further, in the case of a large combine, it is required that the amount of dust is small and the maintenance and management are easy. Therefore, the internal space 24a is an appropriate place.

Next, FIG. 8 will be described. Air conditioning equipment 5
Although there are various places as described above, in a combine where the sun visor 19 is provided, the combine visor is provided in the sun visor 19. Specifically, the sun visor 19 is projected upward to form the projection 19a,
The air conditioner 5 is installed in the convex portion 19a, and the blow grill 6 is provided directly on the air conditioner 5.

This eliminates the need for the air duct 7 between the blast grille 6 and the air conditioner 5, so that cost and weight can be reduced. Further, by providing a switch group such as a switch for turning on / off the conditioned air from the blast grille 6, an air volume adjustment switch, and a switch for switching between cold air, hot air, and air, directly to the air conditioning equipment 5, wiring from the operation post 24 is unnecessary. Becomes Therefore, maintenance and the like can be easily performed. In particular, the air conditioner 5, the blast grille 6, the various switch groups, and the like can be easily attached and detached by simply assembling the pipe to the condenser 15 mounted on the threshing apparatus 1. Further, even if the sun visor 19 itself is removed, the air conditioner 5 can be attached and detached together with the sun visor 19, so that maintenance management becomes easy.

Further, by installing the air conditioner 5 in the sun visor 19, it becomes the highest position among the constituent members of the combine, and the influence of dust can be minimized. Of course, since the air conditioner 5 is provided below the sun visor 19, the influence of rain or the like can be prevented.
