Description

Combine {COMBINE}

The present invention relates to a combine.

At present, the commercially available self-detachment combine combines with a 6-row cutting device for mowing 6 sets of upright grain stems in one stroke.

However, in recent years, commercialization of a combine for farmers that has expanded the cutting width to 7 trillion or 8 trillion for the purpose of further high efficiency of mowing operations is desired.

As such a combine, for example, there is a combine provided with a mowing device for cutting 8 sets described in Patent Document 1.

[Previous Technical Documents]

[Patent Document 1] Japanese Patent Publication No. 2009-44991

In the case of a mowing device that cuts even heat, like the mowing device described in Patent Literature 1, the center position of the mowing width is supported by the tip of the mowing support frame provided on the base of the combine, so It is possible to maintain the weight balance appropriately.

However, the mowing support frame is provided on the left side of the control unit, and when the center position of the wide mowing device of 8 sets is supported on the tip of the mowing support frame, the left end of the mowing device protrudes greatly to the left outside of the body. It becomes.

For this reason, it is difficult to monitor the left end of the harvesting device in the control unit provided on the right side of the body, and it is easy to match in the harvesting operation (alignment of the arrangement between the leftmost grass dividing body of the harvesting device and the upright grain). There is a problem that the efficiency of mowing operation is deteriorated because it cannot be performed.

If the harvesting width protrudes outwardly from the width of the body, the combine cannot be loaded on the track carrier, and transportation by the track becomes impossible. For this reason, there exists a problem which only moves between packagings frequently, and it takes time for the movement between packagings, and the work efficiency falls. In addition, there is a risk that the harvesting device may collide with an obstacle and be damaged while driving.

Also, typically, one raking wheel is required for each of the grain stem introduction paths in the grain stem introduction paths formed between the respective grass dividing frames of the mowing device. For this reason, as the cutting width is increased, the racing wheel increases, and the electric mechanism for driving each racing wheel becomes complicated, and this electric mechanism hinders the conveyance between the mowing grains, and the efficiency of mowing operation is reduced. There is a problem.

In a normal mowing operation, the combine is mowed so that the four sides of the pavement rotate leftward. For this reason, if the right end part of the harvesting | reaping apparatus protrudes largely outward from the gas width | variety, the rightmost dividing frame will collide with a head, and it will become easy to cause damage or deformation.

In addition, in the case where a portion supported left and right from the center position of the cutting width is supported by the cutting support frame, the larger the cutting width, the greater the moment of warpage acting on the cutting support frame. For this reason, the harvesting device is shaken from side to side, and the cutting positions of the grains on the right and left of the harvesting device do not match, and the length of the grains cut off becomes uneven, which causes the threshing device to generate a threshing residue, or the packing marks are disturbed.
