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 off 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 and the like 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. It is engaged with a locking portion 7 provided on the clutch 6 and rotated around a pivot 8, and is prevented from moving upward by a locking member 9 on the fuselage 1 side when the tension clutch 6 is operated to the power transmission position. The attachment/detachment device for the culm processing device is provided with a hook member 10 that can be locked.

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 attach the locking members 4, 4 from above to the receiving members 3, 3 on the left and right sides of the machine body 1.
is locked and held, and then a transmission belt 5 is stretched between the machine body 1 and the culm processing device 2, and
Operate the tension latch 6 to press the transmission belt 5. When the tension clutch 6 is operated, the hook member 10 engaged with the locking portion 7 provided on the tension clutch 6 is rotated about the pivot shaft 8.
The discharge culm processing device 2 is locked by the locking member 9 of the machine body 1.
prevent upward movement.

In addition, when removing the culm processing device 2, when the tension clutch 6 is operated in the direction of loosening the transmission belt 5, the hook member 10 is rotated around the pivot 8 and locked with the locking member 9 of the machine body 1. will be canceled. Therefore, the transmission belt 5 is removed and the discharged culm processing device 2 is removed.
Lift up the receiving members 3, 3 and locking members 4, 4.
All you have to do is release the lock.

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, when the tension clutch 6 of the transmission belt 5 is operated in the tensioning direction, the hook member 10, which engages with the locking portion 7 of the tension clutch 6 and rotates around the pivot 8, locks the fuselage 1. Since it is locked to the locking member 9 so as to prevent upward movement, it is extremely easy to attach and detach the culm processing device 2, and the hook can be opened by operating the tension clutch 6 for power transmission. Since the member 10 is locked, it is possible to avoid forgetting to lock the hook member 10, which is located at the bottom of the discharged culm processing device 2 and is difficult to confirm or operate.

Embodiment The illustrated example uses a cutter as the culm processing device 2, and the cutter 2 has both side frames 11 and 11.
and the rear frame 12, and both side frames 1
Shafts 13 and 14 are installed between 1 and 11, and scraping bodies 15 and 15 and rotary receiving blades 16 and 14 are installed on the shaft 13 at predetermined intervals.
16, and a plurality of cutting blades 17, 1 on the rotating shaft 14.
7 is provided and is configured to cut the culm that is threshed and discharged by the combine harvester. Reference numeral 18 represents a discharge chute for the cut culm that is connected to the lower side of the cutter 2, and 19 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.

20 is the output pulley of the machine 1, 21 is the cutter 2
It is an input pulley and is transmitted by a transmission belt 5.

The tension clutch 6 is composed of an arm 23 rotatable about a shaft 22 and a tension roller 24. Reference numeral 25 designates an operating arm that also functions as a tension spring, and is used to operate the tension clutch 6 on and off.

The hook member 10 is rotatably supported at the center by a pivot 8 to the side frame 11 of the cutter 2, and has an engagement recess 26 at one end that can be engaged with the engagement member 9 of the body 1.
The other end side is provided with a long hole 27 that can be engaged with a locking portion 7 provided on the arm 23 of the tension clutch 6.

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 rotate the operating arm 25 in the direction of arrow A. When the transmission belt 5 is moved and fixed, the transmission belt 5 is tensioned and becomes ready for transmission, and the locking portion 7 provided on the arm 23 slides within the elongated hole 27 and moves the hook member 10 around the pivot 8 as shown by the arrow. The engaging recess 26 of the hook member 10 is engaged with the locking member 9 of the machine frame 1. This engagement recess 26 hangs down diagonally from above and is engaged with the engagement member 9 to prevent the cutter 2 from moving backward and upward.

Therefore, the cutter 2 is mounted with its longitudinal and vertical movements restricted by the locking action between the receiving members 3, 3 and the locking members 4, 4, and the locking action between the hook member 10 and the locking member 9. be done.

Further, the hook member 10 is attached to the tension clutch 6
The locking portion 7 and the elongated hole 27 are constantly engaged to restrict the movement of the hook member 10, and the locking action will not come off due to vibrations of the machine body or the like.

When removing the cutter 2, rotate the operating arm 25 in the opposite direction to when it is installed, loosen the tension clutch 6, and connect the hook member 10 and the locking member 9.
After releasing the lock, the cutter 2 may be lifted upward to release the locking action between the receiving members 3, 3 and the locking members 4, 4.
