The present invention employs the following technical means in order to solve the above-mentioned conventional problems. That is, in a working vehicle in which the control seat 4 is mounted on the traveling vehicle body 2, the air conditioner 5 provided below the step 4a of the control seat 4 is provided with a ventilation duct 7 having a blower grill 6 connected to the end thereof. , The blast grille 6
Is a simplified type air conditioner configured so that the temperature-changed air (hot air / cold air / air blast) blown from the air conditioner 5 is blown out above the control seat 4.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described by taking 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. And the threshing device 1
As is well known in the art, a handling chamber having a handling cylinder mounted on the upper side is arranged and provided on the upper side, and a swing sorting apparatus and a sorting chamber having a pressurized wind are arranged on the lower side. 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.

[0006] As shown in FIGS. 1 to 3, the control seat 4 is located beside the cutting pre-processing device 3 and is provided with a 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 below the step 4a of the control seat 4, and the conditioned air (hot air
(Cool air / blast) is blown out to the ventilation 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.

[0007] As shown in FIGS. 3 and 4, the blast grille 6 is mounted on the upper portion of the air duct 7, and
Opening is provided so as to blow forward from above and behind the operator sitting in the air duct, so that air (hot air, cold air, or air) flowing in the air duct 7 can be blown to the operator side. And In this case, the blast grill 6
As shown in FIG. 3, the right side is blown out to the operator and the left side is blown out to the left side of the operator in the forward direction of the traveling vehicle body 2, so that the culm being transported by the pre-cutting device 3 is The generated dust is arranged to flow away from the control seat 4. When the left blowing grill 6 is used only for dust removal, a blowing configuration in which normal air flows without using adjusted air (hot air / cold air) may be employed.

The sun visor 19, as shown in FIGS. 3 and 4, forms a ceiling by covering the surrounding frame material with cloth, and supports the support rod 20 by tightening screws on both sides of the rear as shown in FIG.
20 ′, and can be freely bent.
The lower part of 0 'is connected to the mounting machine frame 21 by screws 22 so as to be foldable. In this case, the sun visor
19, in addition to the function of blocking the original rain and direct rays,
It also exerts a function of preventing the adjusted air blown out from the blast grille 6 from escaping upward as much as possible.

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 (hot / cold air) maintained 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 control air at the set temperature flows out around the upper part of the control seat 4 so as to cover the upper body of the operator to perform a simple air conditioning operation. 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 embodiment, the air conditioner 5 is provided below the step 4a of the cockpit 4 which is a closed space and is hardly affected by the surroundings. The air can be sucked and used for the air conditioning operation, and the space below the step 4a can be effectively used, so that there is no difference from the combine without the air conditioning equipment 5. Further, the filter 16 for filtering the air to the air conditioner 5 has the dustproof nets 17 and 17 'sandwiched in front and rear in the direction of sucking the outside air, and therefore does not suck the 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 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.

Next, FIGS. 6 and 7 will be described. Instead of the above-mentioned fixed type ventilation duct 7, the ventilation duct 7 is constituted by a bellows type 7a. Therefore, the bellows-type air duct 7a can freely expand and contract and rotate. Further, the lower end of the bellows-type air duct 7a in the air blowing direction is suspended from the sun visor 19 by a hook 7b. A plurality of hooked portions on the other side of the hook 7b are provided arbitrarily throughout the sun visor 19. Therefore, the prepared air can be sent to a position desired by the operator.

Next, FIGS. 8 and 9 will be described. FIG.
Indicates the blowing direction of the prepared air from the blast grille 6 when there is no wind. Of course, the prepared air blows out in the direction of arrow 30 because there is no wind.
However, as shown in FIG. 9, when the cross wind 33 blows to the operator, the prepared air from the blast grill 6 shifts from the operator as indicated by an arrow 31.

Therefore, a wind sensor 32 for detecting the wind force of the cross wind 33 is provided, and from the detection result of the wind sensor 32, the direction in which the prepared air is blown out from the blow grill 6 is calculated.
That is, when the prepared air is affected by the crosswind 33,
The prepared air is directed to the worker. The direction 34 in which the prepared air is blown is such that a variable fin (not shown) provided at the outlet of the blast grille 6 is operated by a motor (not shown). In other words, the resultant force of the cross wind 33 and the direction 34 in which the prepared air is blown out,
It becomes 5.

As a result, even if the cross wind 33 blows, the prepared air blown out from the blast grill 6 is directed in the direction of the operator (arrow 35).
, And the worker can execute the work in a comfortable environment. Next, FIGS. 10 and 11
Will be described. One blower grill 6 is provided at the lower end of one blower duct 7 in the blower direction, and a control seat 4 is provided.
It is a configuration to be installed behind. In addition, a motor 36 is provided at the base of the blower duct 7 so as to freely rotate in the left-right direction. In addition, a wind sensor 32a is installed in front of the control seat 4.

If the detected value of the wind sensor 32a does not detect a cross wind, the air duct 7 is set to 37 as shown in FIG.
Direction (worker direction). In addition, the wind sensor 32
When a detects the cross wind 38, the air duct 7 is directed to the direction 38a. At this time, of course, a calculation is made so that the prepared air from the blast grill 6 goes to the operator, and the motor 36
Is driven. The same applies to the case where the cross wind 39 blows from the opposite direction.

As a result, the cross wind 39, 3
Even if 9 acts, the prepared air blown out from the blow grill 6 of the blow duct 7 always acts in the direction of the worker, so that the worker can work comfortably.

[0019]

As described above, according to the present invention, the air conditioner 5 provided below the step 4a of the control seat 4 is provided with a blower duct 7 having a front end connected to a blower grille 6, and is provided with the blower grille. The air conditioner 6 is configured such that the temperature-changed air (hot air / cold air / air blast) blown from the air conditioner 5 is blown out above the control seat 4.
Is hardly affected by the surroundings and can suck clean air with relatively little dust and can be used for air conditioning. Further, the space below step 4a can be effectively used.
