Description

[Detailed description of the invention] The present invention provides support for the grass divider in the front through the central part between the side-by-side pulling devices installed in parallel at the front of the reaping device and the lateral outer portions of the side-by-side pulling devices. The rod is extended, and a first state located in the center between the parallel pulling devices and a second state located on the lateral outer side of the parallel pulling devices are arranged in front of the parallel pulling devices. This invention relates to a reaping harvester equipped with a forced raking device that can be switched and fixed at will.

In the reaping harvester having such a configuration, conventionally, in order to fix the position of the forced raking device with respect to the divider support rod in the first state and the second state, the lower end connecting member of the forced raking device and the divider Since the device is configured to be fixed in position via multiple bolts and nuts that are inserted through the bracket provided on the support rod, it is necessary to operate the bolts to release and fix the forced raking device and the support rod. Not only does it take a lot of time and effort to do so, but also the bolts,
In particular, it is easy to deform and damage the threaded part, and it is also easy to damage the threaded part when inserting and removing the bolt.As the usage time progresses, it becomes difficult to unfasten and fix the forced rake device and the support rod. A problem arose that became increasingly difficult.

In view of the above-mentioned circumstances, the present invention provides a strong connection strength between the forced raking device and the divider support rod, while also making it possible to quickly and easily unfasten and fix the two. In the above-mentioned device, the forcible raking device is fixed in position relative to the divider support rod in the first state and the second state. The lower end connecting member of the forced raking device is designed to be able to be inserted into and removed from the bracket provided on the divider support rod from the lateral side, and to be fixed in position via a pin-like member that is inserted and removed from above and below in the inserted state. It is characterized by being configured.

That is, among the stresses that act in conjunction with the weeding action and forced raking action of the weed divider, the stress in the vertical and longitudinal directions is absorbed by the lower end connecting member of the forced raking device and the bracket of the divider support rod. Since it can be strongly received by the insertion fitting part, by simply dropping a simple pin-shaped member from above and below between the lower end connecting member and the bracket in the inserted state, both of them can be subjected to stress in the lateral direction. Can be firmly and strongly fixed against resistance.

Therefore, compared to the conventional bolt-and-nut type mounting structure, this not only eliminates the need for special tools such as spanners, but also suppresses breakage and deformation of the pin-shaped member as much as possible, eliminating the need for forced scratching. Although the connection strength between the lifting device and the divider support rod is made strong, the work of unfixing and fixing them can be done quickly and easily.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, in a combine harvester in which a reaping section B is configured to be movable up and down by driving with respect to a main machine A equipped with a threshing device 1, the reaping section B is configured as follows.

At the front of the clipper-type reaping device 2, a pair of left and right side-rotating type pulling devices 3, 3 for pulling up two rows of planted stem culms rearward and upward are installed, with the tips of their pulling claws 3a, 3a touching each other. They are arranged side by side in the left and right direction in a state of facing each other, and the side-by-side pulling devices 3, 3 and the threshing device 1
A vertical conveying device 5 is installed between the reaping culm and the reaping transmission case 6 which gradually changes the reaped stem culm to a sideways posture while conveying it to the threshing feed chain 4. The support rods 8 of the grass dividers 7 extend forward through the central portion between the setting and pulling devices 3 and 3 and the lateral outer portions of the parallel pulling devices 3 and 3, respectively.

A stem culm introduction path 9 to the parallel pulling devices 3, 3 formed between the adjacent weed dividers 7, 7...
Of A and 9B, the width _l1 of the stem culm introduction route 9A located on the control section 10 side is configured to be larger than the width _l2 of the other stem culm introduction route 9B, and the grass divider 7... Between the parallel lifting devices 3, 3,
Vertical rotary forced raking devices 11 and 12 are provided so that the locking claws 11a and 12a are projected and moved from lower front to upper rear along the direction of movement of the aircraft.

Among the forcible raking devices 11 and 12, one of the forced raking devices 11 located on the control section 10 side is
Due to the rotation around the two vertical axes P ₁ and P ₂ , the first state is located in the center between the parallel pulling devices 3 and 3, and the first state is located in the lateral outer side of one of the pulling devices 3. The forced raking device 12 located on the side of the threshing feed chain 4 is attached to the lateral outer side of the other pulling device 3 in a fixed position.

In order to fix the position of the movable side forced raking device 11 with respect to the divider support rods 8, 8 in the first state and the second state, a cross section of approximately the same shape is provided at the lower end of the case 11A of the forced raking device 11. A connecting member 14 having a substantially crank-shaped cross section is fixed via a mounting member 13 shaped like a square, and this connecting member 14 is fixed to the support rods 8, 8 by brackets 15, 15.
The mounting members 13, 1 can be freely inserted and removed only from the lateral side.
3, pin holes 16, 16 formed in the rear divided bracket portions 15B, 15B of the front and rear divided bracket portions 15A, 15B and 15A, 15B constituting the brackets 15, 15.
A pin-shaped member 17 that can be freely inserted and removed from above and below
and a spring 31 for biasing the pin-shaped member 17 to move in the engagement direction.
4 and the divider support rod 8 or the bracket 15 on the 8 side are configured to be fixed in position by inserting the pin-shaped member 17.

The transmission section of the movable forced raking device 11 is constructed as follows.

An input shaft 18 extending rearward from the upper and lower middle portions of the rear surface of the lifting device 3 and an output shaft 19 projecting upward from the reaping transmission case 6 are interlocked with a gear, and the input shaft 18 and the forced raking device 11 input shaft 20, a first transmission vertical shaft 21 extending upward through the back of the pulling device 3, and a transmission shaft extending forward from the upper end of the first transmission vertical shaft 21 through the upper part of the pulling device 3. a horizontal shaft 22 and a second vertical transmission shaft 23 extending downward from the front end of the horizontal transmission shaft 22;
It is linked via. Furthermore, a first transmission case 25 in which the vertical transmission shaft 21 is housed is a fixed transmission case 24 in which the input shaft 18 of the pulling device 3 is housed.
