Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a simplified air conditioner for a working vehicle.

[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.

[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. In addition, when the work vehicle is stored in a small place, the blast grille may be an obstacle.

[0004]

The present invention takes the following technical means in order to solve the above-mentioned conventional problems. That is, in a work vehicle in which the control seat 4 is mounted on the traveling vehicle body 2, the air conditioner 5 installed at an arbitrary position of the work vehicle is provided with a ventilation duct 7 connected to a blowing grill 6 at a tip end thereof. The blast grille 6 is configured so that the temperature-changed air (hot blast, cold blast, blast) blown from the air conditioner 5 is blown out above the control seat 4, and the blast duct 7 is moved forward and backward. A simple air conditioner for a work vehicle, characterized in that the air conditioner is configured to rotate in the direction.

[0005]

According to the present invention, the air (heat / cool air) adjusted by the air conditioner can be sent to the upper part of the control seat through the blower duct 7 and the blower grill 6 because it is configured as described above. . Therefore, the present invention can solve the problems of the conventional type, and can provide a light-weight, small-size (spread-type) combine having a simple air-conditioning effect with reduced manufacturing cost.
Further, since the blast grille 6 rotates in the front-rear direction, it is possible to prevent the work vehicle from being obstructed when the work vehicle is stored in a narrow place.

[0006]

Embodiments of the present invention will be specifically described below. First, the configuration will be described using a combine, which is an agricultural machine, as an example. The combine has a structure in which a threshing device 1 is mounted on a vehicle body 2 having a crawler 8 and a cutting pre-processing device 3 is provided in front of the threshing device 1 for cutting and threshing. 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.

As shown in FIGS. 2 to 4, the control seat 4 is located on the side of the pre-cutting device 3 and 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-conditioning equipment 5 is installed together with the attached device on the machine frame 14 constituting the outer frame of the engine room 13 behind the cockpit 4 and the adjusted air (heat / heat).
(Cold air) is blown out to the air duct 7 and sent upward. A gas pipe and a hot water pipe attached to the air conditioner 5 are laid along the machine body, and the gas pipe is connected to a condenser 15 provided at an upper portion of the threshing apparatus 1, and the hot water pipe is connected to a lower engine side. The former is used for cooling, and the latter is 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. 5, 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.

When the combine is stored in a narrow barn or the like, if the sun visor 19 is provided, the screw 22 is loosened so that the sun visor 19 is tilted forward. Support rods 20, 2
Since 0 ′ passes by the side of the blast grille 6, the sun visor 19 can be folded up to the upper side of the control seat 4. However, the blast grille 6 may interfere. Therefore, the blast grille 6 is configured to be rotatable in the front-rear direction. In FIG. 3, the position moved in the front-back direction is indicated by a two-dot chain line. As described above, in order to rotate the blast grille 6 in the front-rear direction, it is simpler to rotate the blast grille 6 together with the blow duct 7 in terms of configuration. Further, the support arm 18 may be detached and rotated, or an intermediate portion of the support arm 18 may be constituted by a bellows 18a or the like so as to cope with the rotation.

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) maintained at the set temperature into the blower duct 7 and blows out from the blower grill 6 at the tip 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, the air conditioner 5 is installed on the upper part of the machine frame 14 constituting the engine room 13, so that the air conditioner 5 is located at a high position and has relatively little dust and clean air. Can be used for air conditioning. Also, a filter 16 for filtering air to the air conditioner 5
Since the dust-proof nets 17, 17 'are stretched in a sandwich manner before and after in the direction of sucking outside air, dust is not sucked.

When the combine is advanced in the above-described state, the grain culm in the field is cut off by the pre-cutting device 3 and then conveyed upward and backward 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.

When the harvesting and threshing operation is completed and the combine is stored in a barn or the like, the sun visor 19 is folded up to a position above the control seat 4 to store the combine in a narrow space. Then
This time, since the blast grille 6 is in the way,
Is turned forward or backward so that it is folded.
Therefore, the combine can be easily stored in a narrow barn.

Next, FIG. 6 will be described. In the spray grill 6, the left spray grill 6 and the right spray grill 6 are configured to be independently rotatable in the vertical direction.
More specifically, the left and right jet grills 6 are connected to the air duct 7 by bellows 6a. As described above, the spray grill 6 is configured to be fixed to the air duct 7, but there is a problem that it is difficult to cope with the extension of the worker.
Therefore, by independently rotating the left and right spray grilles 6 in the vertical direction, it is possible to blow the conditioned air to an arbitrary position in the vertical direction regardless of the extension of the worker.

Next, FIGS. 7, 8 and 9 will be described. The spray grill 6 is provided on the lower surface side of the sun visor 19. That is, from the air conditioner 5, the air duct 7,
It is configured to be connected to the spray grille 6 via a joint part 23 and left and right bellows 24, 24. The bellows 24 is used because the blast grille 6 is provided in the sun visor 19. Of course, sun visor 1
9 is a fixed type and can be configured so as to extend the air duct 7 as it is and connect it to the injection grill 6 if it is immobile, but the sun visor 19 has the screw 22 as described above. When it is loosened, it turns forward and can be folded above the control seat 4, so that the bellows 24 is used instead of the fixed air duct 7. Thus, even if the sun visor 19 is rotated forward, the bellows 24 can follow the sun visor 19, so that the sun visor 19 can be easily rotated.

In the configuration shown in FIGS. 7 and 8, the blast grill 6
The air-conditioning air blown out from the air-conditioner is installed so as to be directed downward just like the arrow, but as shown in FIG. 9, the air-conditioning air is blown to the worker from diagonally upper right and left sides. You may. In short, when installing the blast grille 6 on the lower surface side of the sun visor 19, any location can be used as long as air-conditioned air can be effectively blown to the operator.
