Abstract

PROBLEM TO BE SOLVED: To provide a bundling string case for discharged straw bundling machine with which waste straw or dust is not piled up on the passage of string, the timing to exhaust the string can be easily estimated and workability and operability can be improved by providing a remaining amount confirming window at the central part of front face of the bundling string case and reducing the vibrations of the bundling string. SOLUTION: The bundling machine is arranged behind the threshing part of a combine, the bundling string case composed of a lower case 60a and an upper case 60b is arranged above the almost center of right and left sides of the bundling machine, and a remaining amount confirming window 61 is provided at the central part of front face of this bundling string case. In this case, it is preferable to arrange a string brake 66, looseness removing rod 67 and string cut sensor 68 on the front face of the lower case 60a housing a string roll 64 around which the bundling string 64a is wound.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a configuration of a binding cord case for accommodating a binding cord of a straw tying machine arranged at a rear portion of a combine.

[0002]

2. Description of the Related Art In the rear part of a combine, there is a case where the threshed straw after threshing is not cut by a cutter device but collected in a straw state and used for other purposes. At this time, a bundling machine may be arranged at the rear part of the cutter device so that the straws can be collected easily, and the straws may be bunched by a certain amount and discharged to the field. In this binding machine, a knot, a discharge arm, and the like are arranged above the straw binding space, and a packer, a needle, a door clutch, a binding cord case, and the like are arranged below the binding space.

[0003]

In the above prior art, since the needle is located below, the binding cord case is necessarily located below the binding space, and the binding cord case is located below the binding space. When it is located below, the binding cord roll cannot be seen directly from the combine driver's seat, so it is not possible to check the remaining amount, and it is necessary to go to the back to check when starting work. If you forget
When the string disappeared in the center of the field, it was necessary to go back to remove the binding string, which was troublesome. Also,
It was also a troublesome task when performing maintenance on the cord brakes, cord guides, etc. of the binding cord.

[0004]

The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described. That is, the binding machine K is arranged behind the threshing section D of the combine, the binding cord case 60 is arranged substantially above the center of the binding machine K on the left and right sides, and the remaining amount confirmation window 61 is provided in the front center portion of the binding cord case 60. Is provided.
