Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an attachment/detachment device for waste culm processing equipment such as a cutter for cutting the waste culm discharged from the threshing section of a combine harvester and a knotter for binding the waste culm.

Conventionally, when installing a waste culm processing device on a combine harvester, the locking member of the waste culm processing device is locked to the receiving member on the upper part of the combine body, and the lower part is fixed with bolts etc. A transmission belt was suspended between the machine body and the waste culm processing device, and the transmission was made possible by operating a tension clutch.

Problems to be solved by the invention As mentioned above, in the conventional technology, not only is the means for attaching and detaching the waste culm processing device complicated, but also the bolts, etc., are located below the waste culm processing device and are difficult to check. It was often the case that the device was forgotten to be tightened. This invention attempts to eliminate the above-mentioned drawbacks.

Means for solving the problem When the culm processing device 2 is removably attached to the rear of the fuselage 1 of the combine, the receiving members 3, 3 on the left and right sides of the fuselage 1 are
The locking members 4, 4 provided on the upper part of the waste culm processing device 2 are locked, and the tension of the transmission belt 5, which is hung between the machine body 1 and the waste culm processing device 2, is installed at the bottom of the waste culm processing device 2. The attachment/detachment device for the waste culm processing device is configured such that a clutch 6 is provided, and the operating arm 7 of the tension clutch 6 and the locking member 8 on the body 1 side can be engaged with each other.

Effect of the invention When attaching the waste culm processing device 2 to the combine harvester body 1, first lift the waste culm processing device 2 and
The locking members 4, 4 are locked to the left and right receiving members 3, 3 from above, and then the transmission belt 5 is hung between the machine body 1 and the waste culm processing device 2, and the operating arm 7
Operate the tension clutch 6 to connect the transmission belt 5.
Rotate it to the pressing side. This operating arm 7 is provided in the waste culm processing device 2, and when the tension clutch 6 is operated in the power transmission direction, the operating arm 7 is locked to a locking member 8 provided on the machine body 1, and the machine body 1 and the waste culm are connected to each other. The connection with the processing device 2 is fixed.

Effects of the invention Since this invention is configured as described above, when the culm processing device 2 is mounted on the body 1 of the combine, the locking parts 4, 4 are engaged with the receiving members 3, 3 of the body 1 of the combine. After that, the tension clutch 6 of the transmission belt 5 is operated in the tensioning direction by the operating arm 7, and the operating arm 7 is engaged with the locking member 5 of the machine body 1, so that the waste culm processing device 2 is moved to the machine body 1. It has an extremely simple structure and is easy to operate. Furthermore, since the lower part of the culm processing device 2 can be fixed by operating the tension clutch 6, there is no danger of forgetting to operate it.

Embodiment The illustrated example uses a cutter as the culm processing device 2, and the cutter 2 is surrounded by both side frames 9, 9 and a rear frame 10, and a shaft 11, 12, the shaft 11 is provided with scraping bodies 13, 13 and rotating receiving blades 14, 14 at predetermined intervals, and the rotating shaft 12 is provided with a plurality of cutting blades 15, 15,
It is configured to cut off the culm that is threshed and discharged by the combine. Reference numeral 16 represents a discharge chute for the cutting culm that is connected to the lower side of the cutter 2, and 17 represents a dropper device that is attached to the rear of the cutter 2.

Vertical cylindrical receiving members 4 are provided on one side of the body 1 at the top and bottom, and locking members 4, 4 each consisting of an upper and lower vertical shaft provided on one side of the cutter 2 can be inserted from above.

Further, a receiving member 3 extending rearward is provided at the upper part of the other side of the body 1, and a locking member 4 consisting of a horizontal pin is configured to be able to be locked from above at the upper part of one side of the cutter 2.

An output pulley 18 of the machine body 1 is an input pulley of the cutter 2 and is transmitted by a transmission belt 5.

The tension clutch 6 is composed of an arm 21 rotatable about a shaft 20 and a tension roller 22.

The operating arm 7 is formed by extending the tension spring 23 of the tension clutch 6, and is configured such that its free end side can be locked to the locking member 8 of the body 1. The locking member 8 has a groove 24 formed in the end surface of the shaft that projects laterally from the body 1, and the operating arm 7 is fitted into the groove 24. Further, the operating arm 7 is formed with a bending portion 25 for preventing removal and a curved gripping portion 26. Further, 27 is a locking member of the operating arm 7 at the tension clutch 6 disengaged position, and 28 is a handle.

When attaching the cutter 2 to the combine harvester body 1, first lock the locking members 4, 4 of the cutter 2 to the receiving members 3, 3 of the machine body 1, and then connect the output pulley 18 and input pulley 19. When the transmission belt 5 is hung between them and the operating arm 7 of the tension clutch 6 provided on the side frame 9 of the cutter 2 is rotated in the direction of arrow A, the clutch 6 is rotated about the shaft 20 and the tension The transmission belt 5 is moved by the roller 22.
Press to enter the transmission state.

At this position, the operating arm 7 is fitted into the groove 24 of the locking member 8 provided on the body 1.

Therefore, the cutter 2 can lock the receiving members 3, 3 and the locking members 4, 4, and the operation arm 7 and the locking member 8.
It is fixed by restricting back and forth and up and down movement by engagement with the holder.

When removing cutter 2, reverse the installation process.
Remove the operating arm 7 from the engagement part 8, loosen the tension clutch 6, remove the transmission belt 5, lift the cutter 2 upwards, and release the engagement between the receiving members 3, 3 and the locking members 4, 4. good.
