BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for arranging a tension clutch of a combine.

[0002]

2. Description of the Related Art Conventionally, as one form of a tension clutch disposing structure in a combine, there is one shown in FIG.

[0003] That is, such a structure has a mission section a
The input shaft b and the output shaft d of the engine c are arranged in front and rear parallel to each other, and a traveling drive mechanism e is provided between both shafts b and d.
A clutch pedal g provided in the driving section is interlockedly connected to a tension clutch f provided in the traveling drive mechanism e via an interlocking mechanism h.

[0004]

However, as shown in FIG. 5, the above-mentioned interlocking mechanism h mounts an arm k on a pedal support shaft j for supporting a clutch pedal g, and at the rear of a transmission section a. Since the arm n is attached to the tension arm support shaft m which is laterally suspended, and both arms k and n are interlockingly connected via the connecting rod p on the side opposite to the side where the input shaft b of the transmission portion a projects, the tension is increased. Arm support m
Needs to be formed wider than the left and right widths of the transmission part a. Further, the traveling drive mechanism e is disposed on one side of the transmission part a, and the connecting rod p is disposed on the other side. For this reason, a large space is required around the mission section a, and the combine itself has become large.

[0005] For this reason, there has been a problem that the turning radius of the combine becomes large, steerability is deteriorated, and a large storage space is required.

[0006]

Therefore, according to the present invention, an elevating and mowing portion is attached to the left front of a chassis frame mounted on a crawler type traveling portion, and the chassis is attached to an operating portion provided in a right front half portion. The clutch pedal, which is pivotally supported by the support member attached to the frame, is arranged.The input shaft of the transmission unit and the output shaft of the engine are arranged parallel to each other in front and rear, and a traveling drive mechanism is interposed between both shafts. In addition, in a combine in which the clutch pedal is interlockingly connected to a tension clutch provided in the traveling drive mechanism via an interlocking mechanism, the interlocking mechanism is disposed on a side wall of the transmission unit where the input shaft protrudes. A tension arm support shaft for pivotally supporting the tension arm of the tension clutch is attached to the side wall. Between the output shaft of the transmission unit and the output shaft of the engine and the input shaft of the transmission unit in a side view. The input shaft of the raising / removing unit, which is located between the two shafts and above the two shafts, is arranged in front and rear parallel to each other, and a tension clutch is provided on the reaping transmission mechanism interposed between the two shafts. A tension arm of the combine clutch is pivotally supported on the tension arm support shaft to provide a tension clutch arrangement structure of a combine.

Therefore, the traveling drive mechanism, the interlocking mechanism, and the mowing transmission mechanism are disposed on the input shaft side, which is one side of the transmission section, and a narrow space between the operating section and the raising / cutting section is provided. Can be used effectively, the body width to the raising and cutting section can be reduced and the combine itself can be made compact, the turning radius of the combine can be reduced to improve running performance, and the storage space can be reduced. And the problem of stepping on the culm by the crawler can be eliminated.

[0023]

According to the present invention, the following effects can be obtained.

Since the interlocking mechanism is disposed on the input shaft side, which is one side of the transmission section, the space around the transmission section can be effectively used, and the size of the combine itself can be reduced. The turning radius can be reduced, the steerability can be improved, and the storage space can be reduced.

Since the tension arm support shaft for pivotally supporting the tension arm of the tension clutch is mounted on the side wall of the transmission portion from which the input shaft protrudes, the tension roller mounted on the tension arm and the traveling drive of the traveling drive mechanism are provided. The belt can be placed in close proximity,
The clutch connection operation of pressing and tensioning the traveling drive belt by the tension roller can be reliably performed.

Since the chassis frame is provided with a support member for rotatingly supporting the clutch pedal, even if the cabin surrounding the driving section is of an anti-vibration suspension structure, the clutch is affected by the vibration of the cabin. Vibration of the pedal can be prevented. Therefore, the tension clutch interlockingly connected to the clutch pedal via the interlocking mechanism does not malfunction, and the clutch connection / disconnection operation can always be reliably performed by the clutch pedal.

Since the tension arms of the tension clutches provided in the traveling drive mechanism and the mowing transmission mechanism are pivotally supported on a single tension arm support shaft and share the same tension arm support shaft, the number of parts is reduced. In addition to being able to reduce, the tension roller provided on the tension clutch of the mowing power transmission mechanism and the mowing power transmission belt can be arranged at close positions, and such a tension roller can be reliably connected to the clutch similarly to the tension roller of the traveling drive mechanism. Action can be taken.
