BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain culm raising device for combine harvesters, and in a grain culm raising device provided in a reaping device, assists raising of fallen grain culms along the front side of a main grain culm raising case. It can be used for those provided with an auxiliary grain culm raising case.

[0002]

2. Description of the Related Art In a large combine harvester for multi-row cutting, a grain stalk provided on a harvesting device is caused by the grain stalks lying down and the culm being disturbed by the adjacent grain stalk row and the like. Since the raising device hinders the raising work of the overlaid grain culms only with the main grain culm raising cases, in recent years, the main grain culm raising cases have been made to correspond to the main grain culm raising cases along the front side of the main grain culm raising case. By providing an auxiliary grain culm raising case parallel to the traveling direction of the machine, it is possible to unravel the adjacent grain culm row before the main grain culm raising case raises it. The raising work by the raising case can be smoothly performed.

However, in the transmission structure of the auxiliary grain stalk raising case, conventionally, the upper side of each auxiliary grain stalk raising case is connected by a horizontally long transmission case, and only from one end side thereof. Power is supplied, and the auxiliary grain culm raising case at the right end, which is not always necessary in the counterclockwise cutting work, is also integrally connected and transmitted, so the cutting operation is mainly performed counterclockwise. In this case, unnecessary weight and cost are added by the auxiliary grain culm raising case at the right end, and the sight of the operator is obstructed by the transmission case at the right end side, which hinders the operation and transmission. Since it is performed from only one side, there are many factors that are disadvantageous in terms of functionality, economy, operability, and durability, such as load concentration and reduced durability.

In view of the above, the present invention provides, in a grain culm raising device for raising and treating an overlaid grain culm, a transmission structure of an auxiliary grain culm raising case which is arranged corresponding to the main grain culm raising case, which has a functional,
It is intended to be constructed so as to be advantageous in terms of economy, operability, and durability.

SUMMARY OF THE INVENTION The present invention provides auxiliary grain culm raising cases 6 to 9 arranged along the front side of main grain culm raising cases 1 to 5 on which grain culm raising chains are stretched. , Only the auxiliary grain culm raising case 6 in front of the operation seat 10 on the front side of the vehicle body is independently supported, and these auxiliary grain culvert raising cases 7 to 9 are extended to the upper end portions of the auxiliary grain stalk raising cases 7-9. A combine grain cereal raising device is constructed by laterally arranging transmission cases 11 and 12 having a transmission mechanism for transmitting power to the grain stalk raising cases 7 to 9 to the grain stalk raising chains.

[0006]

With the above construction, in the harvesting work of the combine, when raising the grain culm having a large disturbance of the culm by falling down by the grain culm raising device arranged on the front side of the reaping device, first, , An auxiliary grain culvert raising case 6 which is located in front of the operator's seat 10 and is supported independently of the front side of the main grain culm raising case 1 and is independently driven from the right end of the lateral transmission case of the upper part of the cutting device. And relatively driven along the front sides of the main grain culm raising cases 2 to 5 and connected and driven by the transmission cases 11 and 12 from the left end of the lateral transmission case above the cutting device. With each of the auxiliary grain culm raising cases 7 to 9 of the above, the main grain culm raising cases 1 to 5 are unwound by unraveling the adjacent grain culm rows.
The raising work can be performed smoothly.

With such a configuration and operation, the auxiliary grain culm raising case 6 located at the right end of the cutting device and the other auxiliary grain stalk raising cases 7 to 9 located at the left side are separately provided. The auxiliary grain culm raising case 6 can be detached by itself when necessary, and if it is unnecessary, the auxiliary grain culm raising case 6 can be detached from the beginning. And it can reduce cost and improve functionality and economy. In addition, since the transmission case is not required in front of the operator's seat 10 because the transmission is performed from both the left and right ends, the operability can be improved and the lifting load can be improved. Can be dispersed to improve durability.
