Combine harvester

Abstract

The invention relates to a united reaping machine which can be excellently operated by fingers of a hand holding an operating bar to, with less error operations, adjust height of a reaping device, height of the machine and gesture of the machine body, and to perform the steering united reap of the machine body, and which can improve the efficient of reaping work via the united reaping machine. A face at front side of a holding part (70) of the operating bar (59) is provided in parallel with an ascending switch (SW1) and a descending switch (SW2) both for ascending and descending operations ofthe reaping device in up and down directions; a position between the ascending switch (SW1) and the descending switch (SW2) is provided with an error operation preventing projection part (71) which projects more than pressing operational surfaces of the switches. In addition, the same projection part (73) is also provided at the position between a machine height ascending switch (SW3) and a machine height descending switch (SW4) which are provided on the surface of left side of the holding part (70).

Description

technical field [0001] The present invention relates to combine harvesters. Background technique [0002] Conventionally, an operation lever that raises the harvesting device by operation in the front-rear direction and turns the vehicle body by operation in the left-right direction is provided on the control unit provided on the vehicle body of the combine harvester. [0003] Various operating switches are provided on the grip portion of the operating lever. As this prior art, as disclosed in Patent Document 1 (Patent Document 1: Japanese Unexamined Patent Application Publication No. 2000-71801), there is provided a forward and backward movement on the grasping portion of the operating lever provided on the operating portion of the construction machine. The switch for shifting, the acceleration switch and deceleration switch for driving shift, and the technology that the switch for siren is installed on the side of the grip part. These switches are arranged within a range...

AI Technical Summary

Problems solved by technology

[0006] However, in the case of such a structure, for example, in the harvesting driving process, when the combine harvester is necessary to operate the steering switch due to deviation from the grain stalk, if the operator makes a mistake and operates the harvesting device lifting switch, the harvesting device will Descending against the operator's will, causing the harvesting device to protrude into the ground

That is, in the above-mentioned prior art, there is a problem that the operability of the combine harvester is very poor and the efficiency of the harvesting work is reduced.
