Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmission coupling device for a reaper that is attached to a multi-purpose combine harvester that can be used for various crops such as rice, wheat, and beans.

Conventionally, a threshing machine has been equipped with a proprietary type reaper that can be selectively installed and an ordinary reaper (reduced slider), and when the former is installed, threshing is carried out while transporting the husk with a foot chain. The K17'c multi-purpose combine harvester has been put into practical use so that when the latter is installed, the entire culm is fed to the threshing machine for threshing. It is desirable that the reaper used in this type of multi-purpose combine harvester be easy to attach and detach from the threshing machine, but in conventional ordinary reapers, the reaper is divided into a forest, a reaping device, and a lifting device. The reaping device was installed on the body, and the reaping device was configured to be transmission connected to the lifting device via a universal joint. Therefore, the KVi must be used to attach the reaping device to the lifting device, and after the installation, a universal fitting operation must be carried out, making attachment and detachment extremely complicated.

This invention was devised in view of the above, and its purpose is to connect the plowing and reaping device to the lifting device through a gear, thereby making it possible to attach and detach the plowing and reaping device. It is an object of the present invention to provide a transmission coupling device for a reaper.

In order to achieve the above object, this FIA expansion and reaping device 7 and a lifting device 11 equipped with a conveyor 9 are detachably provided, and a counter shaft 1 of the reaping device 7 is provided.
A gear 15 fixed to the lower end shaft 17 of the lifting device 11 is detachably connected to a gear 19 fixed to the lower end shaft 17 of the lifting device 11.

Hereinafter, one embodiment of the present invention will be explained in detail using the drawings.

In FIGS. 1 and 2, the traveling device 23 of combine harvester A
is equipped with a pair of left and right running rollers 25, and on a body frame 27 that connects these running rollers 25,
A threshing machine 35 is equipped with a handling barrel 29 for threshing, a sorting device 31, a foot chain 33 for a threshed husk culm conveyance train, and the like.

The combine A is equipped with a normal type reaper 37 and a self-removal type reaper (not shown) that can be selectively attached to and detached from the threshing machine 35. The machine 374; J is divided into a reaping device 7 and a lifting device 11, and both devices 7 and 11 are detachably connected by a suitable connection mechanism. At the lower end of the reaping device 7, a clipper-shaped cutting blade 3 is located behind the weeding body 39 and is supported by a support rod 41 in close proximity to the ground. A spiral blade 43 for collecting culms protruding from the curved surface of the cylinder, and a plurality of crank fingers 45 for collecting culms that rotate while moving back and forth with respect to the circumferential surface of the cylinder by an eccentric mechanism provided inside the cylinder. A scraping auger 5 equipped with an auger shaft 47 is mounted on the auger shaft 47. Further, diagonally above the scraping auger 5, there is a pulling reel 1 which is connected by a crank and is equipped with a single ring 49 and a large number of tines 51 which are arranged in parallel in the axial direction at six locations on the outer periphery of the single ring 49 and are suspended from each other. but,
The tip of a swingable arm 53 is supported by a reel shaft 55, and the height of the pulling reel 1 is adjustable by a drive device 57 such as a hydraulic cylinder.

On the other hand, the lifting device 11 includes a sprocket 6 of the upper end shaft 59.
1, a sprocket 63 on the lower end shaft 17, and a wide chain conveyor 65 stretched in contact with these.

At the upper end of the reaping device f&i7, a pair of left and right engaging portions 69 are provided which are detachably engaged with both ends of a support pipe 670 provided at the lower end of the lifting device 11.

Further, at the upper end of the conveying device 11, a beater shaft 73 of a beater 71 for scraping the culm provided at the front end of the threshing machine 35 is provided.
An engaging portion 75 is provided which is detachably engaged with.

The threshing machine 35 and the reaping device 7 are connected by a link 77, and a drive device 79, such as a hydraulic cylinder, is attached to the machine frame 27. The cutting height is configured to be adjustable.

FIG. 3 shows a power transmission path diagram of the reaping device 7 and the lifting device 11, which are constructed as follows.

That is, the output shaft 83 of the prime mover 81. J: pulley 8
5 and the pulley 89 on the counter shaft 87 and the belt 91
The belt 97 is then passed between another pulley 93 provided on the counter shaft 87 and a pulley 95 fixed to one end of the beater shaft 73.
A belt 103 is passed between a pulley 99 fixed to the other end of the shaft 73 and a pulley 101 fixed to one end of the lower end shaft 17, so that they are interlocked to drive the conveyor 9.

Further, a gear 19 fixed to the other end of the lower shaft 17 as shown in FIG.
A gear 15 fixed to one end of a counter shaft 13 pivotally supported by a counter shaft 13 is removably engaged via a counter gear 21. Counter gear 21i, lifting device 11
It is rotatably supported on the side frame. Boos IJ-105, 107 of different diameters fixed to the other end of the counter shaft 13
17) The belt 113 is passed between one of the pulleys 105 and one of the pulleys 109 and 111 of different diameters fixed to one end of the auger shaft 47, and the belt 113 is passed around the other pulley 109 of the counter shaft 13. - A belt 119 is passed between the reel 107 and the pulley 117 on the cutting blade drive shaft 115, and furthermore, pulleys 123 and 125 of different diameters are fixed to the other pulley 111 of the auger shaft 47 and one end of the reel counter shaft 121. One of the pulleys 1
23 and pass the belt 127 to the other pool.
The belt 131 is passed between the IJ-125 and the pulley 129 fixed to one end of the reel shaft 55, and the reel 1. Cutting blade 3. and are interlocked to drive the scraping auger 5.

In addition, in the figure, 133 is a straw removal chino, and 135 is a straw removal cutter.

In the above configuration, when the ordinary type reaping machine 37 is used for harvesting of wheat, beans, etc., by engaging the engagement part 75 of the lifting device 11 with the beater shaft 73 of the threshing machine 35, the raising The feeding device 11 is attached to the threshing machine 35, and the belt 103 is passed over the pulley 99 on the second beater shaft 73 and the pulley 101 on the lower end shaft 17 of the lifting device 13 for interlocking connection.

Therefore, by engaging the engaging portion 69 of the reaping device 7 with the support pipe 67 of the lifting device 11, the reaping device 7 is attached to the lifting device 11, and the gear 15 on the counter shaft 13
is engaged with the gear 19 on the lower end shaft 17 via the counter gear 21 for interlocking connection, and then one end of the link 77 is connected to the reaping device 7 side.

When the machine is run after being prepared in this way, the culms in the field are swept away by the weed cutting body 39, and the fallen culms are raised by the rotation of the tines 51 of the rotating lifting reel 1. After the root portion of the raised culm is cut off by the cutting blade 3, the culm is gathered to one side by the spiral blade 43 of the raking auger 5, and is raked into the conveyor 9 by the crank finger 45 and lifted up and transported. Ru. When the conveyance terminal end is reached, the entire culm is scraped into the threshing machine 35 by the beater 71 and threshed by the handling cylinder 29.

When the work is finished and the machine is stored, or when replacing the normal type reaper 37 with a self-removal type reaper, the normal type reaper 37 is replaced with the threshing machine 35 by the reverse operation of the device.
to separate from

In this invention, a reaping device and a lifting device equipped with a transport conveyor are detachably provided separately, and a gear fixed to a counter shaft of the reaping device is connected to the lifting device. This transmission coupling device for a reaping machine is characterized in that it is configured to be releasably connected via a counter gear to a gear fixed to the lower end shaft of the device, so all you have to do is attach the reaping device to the lifting device.
