Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a combine harvester in which a driver's seat is arranged side by side next to a reaping pretreatment device and a cabin is provided to cover the driver's seat.

[Conventional technology]

Conventionally, in this type of combine harvester, the cabin has only been provided with an opening for getting on and off.

[Problem that the invention attempts to solve]

Therefore, it is conceivable that an opening/closing door may be provided for this opening to make the cabin airtight to prevent straw waste generated by the pre-harvesting treatment device from entering the cabin, but in this case. This would require additional equipment such as an air conditioner, which could be expensive.

The purpose of the present invention is to provide an apparatus that uses inexpensive equipment, yet provides functions comparable to conventional configurations, and maintains good operability.

[Means for solving problems]

The features of this invention are that an opening is provided on the side of the cabin opposite to the reaping pre-treatment device, a suction port is provided on the top surface, a suction fan is attached to this suction port, and this suction fan The outside air sucked in from the suction port by the air inlet is discharged through the opening, and the functions and effects are as follows.

[Effect]

From the characteristic configuration, by making the outside air sucked in by the suction fan act on the driver and exhausting it through the opening, the suction fan has a cooling function for the driver, while reducing the cabin internal pressure from the outside air. It is held high to prevent straw debris from entering through the opening. Furthermore, since the intake port for the outside air introduced into the cabin is provided on the top surface of the cabin, relatively clean air from above the combine can be taken in, and less straw waste and the like are brought into the cabin. Moreover, since the suction fan itself is located on the top surface and is configured to exhaust air toward the side opening, it is possible to suppress dust from flying up inside the cabin due to the downward airflow from the suction fan.

[Effect of idea]

As a result, the inside of the cabin can be filled with clean air and the operating environment can be improved, and the structure for this purpose only requires that a suction fan be attached to the intake port on the top side.

〔Example〕

As shown in FIGS. 2 and 4, the pre-harvesting device is equipped with a lifting device 1, a reaping device 2 for reaping the lifted grain culm, and a vertical conveying device 4 for conveying the harvested grain culm toward a rear threshing device 3. A control section B including a driver's seat 5 and a boarding step 6 is arranged on the lateral side of the processing device A to constitute a combine harvester.

A cabin 7 that covers the driver's seat 5 is provided for the driver's seat 5, and the structure of the cabin 7 will be described below. This cabin 7 has three sides made of transparent resin plates, and has an opening 8 for boarding on the side opposite to the side where the reaping pretreatment device A is present.
In addition, the lower ends of the remaining three sides are connected to a front operation box 9 surrounding the driver's seat 5, a side operation box 10, and
It is supported and installed across the engine bonnet 11.

Next, the mounting structure of the cabin 7 will be described in detail. A steel frame 12 such as a flat steel (a vipe may also be used) is embedded in the periphery of the resin-made cabin body extending over both sides and the upper side of the opening 8 to provide a reinforcing structure.
At both lower ends protruding downward from the main body of the second cabin,
Lateral boss 13, 1 along the front and back direction of the cabin 7
3 is fixed. On the other hand, horizontal fixing pins 14, 14 corresponding to the horizontal bosses 13, 13 are fixed to the brackets on the front operation box 9 on the aircraft frame side and the engine bonnet 11, and anti-vibration rubber is installed inside the horizontal bosses 13, 13. Fitting the bosses 13, 13 onto the pins 14, 14 with the sleeve interposed,
Constructed so that it can be freely disconnected using a cotter pin.

Further, a mounting seat 28 that can be attached to the machine frame is provided at the lower end of the side surface of the cabin on the side of the reaping pretreatment device A, and the cabin 7 is fixed to the machine frame using this mounting seat 28.

As shown in FIG. 1, a suction fan 18 for introducing outside air is provided on the front side of the top surface 7A of the cabin 7.
is provided, and by introducing the outside air with less dust from the uncut side above the machine body through the suction port 19 provided near the suction fan 18 and exhausting it from the opening 8, the inside of the cabin 7 is made to have a high pressure. The structure is such that it is held in place to prevent dust from entering.

Next, the structure of the openable window 20 provided on the side of the reaping pretreatment device A of the cabin 7 will be explained. As shown in FIGS. 3 and 4, plate brackets 2 are attached to the upper ends of the window frames 21 and 21 located on both sides.
2 and 22 are erected, and hinges 23 and 23 are connected with pins to the plate-shaped brackets 22 and 22, so that the window 20 is configured to be vertically swingable around the pin axis Y.

The window 20 is made of a transparent resin plate, and is configured to be foldable in two along a fold line parallel to the pin axis Y. Guide mechanisms 25 and 2 are provided on the window frames 21 and 21 to guide the lower end of the window 20 upward.
5 is provided. The guide mechanism 25 is made of channel steel, and a guide roll extending from the lower end of the window 20 can be loosely fitted into the channel steel. The guide mechanisms 25, 25 are provided with a rising portion diagonally upward to protrude outward at the upper end.
A horizontal portion is provided horizontally toward the cabin 7 from the upper end of this rising portion, and this rising portion and the horizontal portion constitute an overhang portion 25A. Therefore, window 2
When the handle 27 provided at the lower end of the window 20 is lifted upward, the lower end (free end) 20a of the window 20 is lifted along the guide mechanism 25, and the window 20 gradually bends in half, as shown in the figure. As shown in FIG.

Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
