Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine cabin provided to surround a driver's seat, an operation box on the front side of the driver's seat, and the like.

[0002]

[Prior art]

 Conventionally, as a cabin for this kind of combine, for example, in the microfilm of Japanese Utility Model Application No. 53-10269 (Japanese Utility Model Application Laid-Open No. 54-114212), the front side portion is left in one side portion of the cabin and only the rear side portion is opened and closed. There is disclosed a combine cabin that is capable of opening and closing an openable door.

The microfilm of Japanese Utility Model Application No. 52-176988 (Japanese Utility Model Application Laid-Open No. 54-102811) has an opening / closing door in which the front side portion is left on one outer side of the cabin and only the rear side portion can be opened / closed. There is disclosed a combine cabin in which a − is arranged on the side of the seat and is openably and closably provided around a longitudinal axis.

[0004]

[Problems to be solved by the device]

 According to such a conventional technique, even if the opening / closing door is opened, the area of the entrance / exit obtained by this is small, and the position of the entrance / exit is shifted in the front-rear direction with respect to the position of the seat, so that the passenger can get on / off the cabin smoothly. There was a problem that I could not do it. For example, a combine cabin disclosed in Microfilm of Japanese Utility Model Application No. 53-10269 (Japanese Utility Model Application Laid-Open No. 54-114212) has a trapezoidal front side portion along a front wall in a forward tilted posture at one outer side portion of the cabin. Is left as a fixed side wall, and only a rectangular rear side portion located behind this is provided as an opening / closing door so that it can be opened and closed.

Therefore, when the opening / closing door is opened, only the rectangular rear side portion is opened, and the area of the entrance / exit becomes small. Therefore, it is not possible to get on and off the cabin smoothly. The combine cabin disclosed in the microfilm of Japanese Utility Model Application No. 52-176988 (Japanese Utility Model Application No. 54-102811) has a triangular front side portion along the front wall in a rearwardly tilted posture at one outer side portion of the cabin. Is left as a fixed side wall, and only a rectangular rear side portion located behind this is provided as an opening / closing door so that it can be opened and closed. Further, the opening / closing door is configured so as to be openable and closable in a front opening around the longitudinal axis arranged on the side of the seat.

Therefore, when the opening / closing door is opened, only the rectangular rear side portion is opened, and the area of the entrance / exit becomes small. Further, since the vertical axis which is the opening / closing fulcrum of the opening / closing door is arranged on the side of the seat, even if the opening / closing door is fully opened to open the front side, the portion directly to the seat is not opened. Therefore, it is not possible to get on and off the cabin smoothly.

[0007]

[Means for Solving the Problems]

 The present invention has taken the following technical means in order to solve the above problems. That is, the reaper 3 is arranged in front of the machine base 2 equipped with the traveling crawler 1, and the driver's seat 6 and the operation box 9 installed in front of the seat 6 are surrounded in front of the machine base 2. In order to ensure that the cabin 10 is provided, an opening / closing door 16 that can open and close substantially the entire outer side portion of the cabin 10 is provided around the vertical axis P arranged behind the seat 6. This is the structure of the combine cabin.

[0008]

[Action]

 When the opening / closing door-16 is opened during driving, the opening / closing door-16 opens frontward about the vertical axis P behind the seat 6. Then, the opening / closing door 16 is closed. When the driver finishes driving and goes out of the cabin 10, the opening / closing door-16 is opened. At this time, the opening / closing door-16 opens forward around the vertical axis P.

[0009]

[Effect of device]

 Since the opening / closing door 16 of the cabin 10 can open and close the outer side portion of the cabin 10 over substantially the entire surface, when the opening / closing door 16 is opened, the outer side surface of the cabin 10 is substantially closed. The entire area is open and the entrance / exit area can be very large. Further, since the vertical axis P, which is the opening / closing fulcrum of the opening / closing door-16, is arranged behind the seat 6, when the opening / closing door-16 is opened to the front opening, all positions up to the side directly to the seat 6 are opened. It will be released. Therefore, getting on and off the cabin 10 can be carried out very smoothly.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. On a machine base 2 equipped with a traveling crawler 1, a reaping section 3 is arranged in the front, and a threshing section 4 is arranged in the rear, and a threshing section 4 is provided. There is a paddy treatment section 5 on the lateral side of the same, a driver seat 6 in front of the paddy treatment section 5 and on the rear lateral outer side of the reaping section 3, and a space below the seat 6. An engine 8 with a radiator 7 which is arranged outward in the above, and an operation box 9 which is erected upright on the front side of the seat 6 are arranged.

Reference numeral 10 denotes a cabin that is frame-structured to surround the driver's seat 6, the engine 8 with the radiator 7, the operation box 9, and the like, and includes a pair of left and right front columns 11 and a rear column 12. A pair of left and right of the above is erected from the machine base 2 side, and another member 13 is connected between the upper ends of these columns to form a cabin frame, and the front surface thereof is provided with the windshield 14 and both sides. The side is covered with a window glass 15, and the upper surface and the rear surface are covered with a sheet or the like.

[0012] The cabin front wall 10A, which includes the front support column 11 and the windshield 14, extends forwardly and upwardly from the front end of the deck 2A portion in the operator's cab so that the upper end side is located forwardly of the lower end side. It is configured in a substantially forward leaning posture. Reference numeral 16 denotes an opening / closing door, which is constructed so that the entire surface between the front and rear struts 11 and 12 can be opened and closed, and is opened to the outside outward about the longitudinal axis P near the rear side of the engine 8. It is configured. In other words, the opening / closing door 16 opens and closes with the hinge 17 pivotally supported by the rear support column 12 as a fulcrum, and when opened to the outside, the outside surface side of the engine 8, seat 6, operation box 9, etc. is greatly expanded. It is open to the public.

Reference numeral 18 denotes a dust-proof net which is provided on the opposite side of the radiator 7 and communicates with a cooling chamber 21 of the radiator 7 via an intake chamber 19, and the dust-proof net 18 is provided. The intake chamber wall 20 including it is configured to be separable and connectable to the chamber wall 22 of the cooling chamber 21 via the seal rubber 23, and the dustproof net 18 is configured integrally with the opening / closing door-16. By doing so, it is possible to open and close around the same axis P.

In the embodiment shown in FIG. 3, the upper front portion of the cabin 10 is formed to bulge forward of the operation box 9, and the driver is able to stand up during standing work in the bulged portion 10a. It is configured so that work can be performed while checking the state of the protruding and raising of weeds from above.
