Description

[Detailed description of the invention] The present invention has a pair of left and right horizontally rotating pulling devices installed in parallel at the front of the reaping device, and a vertically rotating forced raking device in front of the parallel pulling devices. The purpose of the installed reaping and harvesting machine is to use the above-mentioned forced raking device to exhibit appropriate and good effects depending on various conditions such as the reaping work form, the degree of lodging of the planted stem culm, and the direction of lodging. The purpose of the present invention is to make it possible to change the state of use to the desired state, and to make the changeover quick and easy.

That is, in the reaping and harvesting machine according to the present invention, the forcible raking device is placed in three positions: at the center between the parallel pulling devices and at both lateral outer sides of the parallel pulling devices. Since it is characterized by being configured to be able to swing and fix freely, for example, when mowing under conditions where the planted stem culm is lying down, the forcible raking device can be installed in parallel. By switching the pulling device to the lateral outer side of the uncut field side, it is possible to smoothly separate the reaped stem culm group and the uncut stem culm group from side to side, and when mowing in the same rotation. However, if the planted stem culm is in a pilose state, the forcible raking device can be switched to a state where it is located on the lateral outer side of the mown field side of the parallel pulling device. Damage to the stem culm due to excessive raking action can be avoided, and furthermore, when mowing in opposite directions, by switching the forced raking device to a state in which it is located in the center between the parallel pulling devices, the above-mentioned Stem culm caused by separating the trailing stalk culm leaning forward from the leading stalk culm that is raised by the setting and pulling device, and causing the leading stalk culm and the trailing stalk culm to be raised simultaneously. As mentioned above, one forced raking device can be used to avoid uprooting and breaking of culms.
The device can be switched to use in response to various work conditions in order to perform an appropriate and good operation in any case, and the forcible raking device is configured to be switched to the three positions mentioned above by swinging. By doing so, compared to a device in which the position of the forced raking device is changed by attaching and detaching it, it is possible to quickly and easily change the use in response to the conditions mentioned above, which is very convenient from a practical point of view. .

Hereinafter, an embodiment of the present invention will be described based on the drawings. In a combine harvester in which a reaping section B is configured to be movable up and down by driving for the main machine A equipped with a threshing device 1, the reaping section B is as follows. Configure.

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. A grass divider 7B is inserted forward through the center portion between the setting and pulling devices 3 and 3 and the lateral outer portion of the parallelly installed pulling devices 3 and 3, respectively.
Support rods 8B, 8A, and 8C of 7A and 7C are extended.

the adjacent grass dividers 7A, 7B and 7B;
Among the stem culm introduction paths 9A and 9B to the parallel pulling devices 3 and 3 formed between 7C, the width l ₁ of the stem culm introduction path 9A located on the control section 10 side is set to the other stem culm. The width is larger than the width _l2 of the introduction path 9B, and a locking claw 11 is provided between the grass dividers 7A, 7B, 7C and the parallel pulling devices 3, 3.
A vertically rotary forced raking device 11 is provided, which is configured to project and move the vehicle a from the lower front to the upper rear along the direction of movement of the aircraft.

Thus, at the upper part of the back side of the parallel pulling devices 3, 3 and at the upper end of the vertical transmission case 12, which is parallel to the reaping transmission case 6, a transverse direction with respect to the parallel pulling devices 3, 3 is provided. The transmission case 13 is fixedly connected, and a transmission case 14 is constructed between the sideways transmission case 13 and the forced raking device 11 so as to bypass the upper part of the parallel pulling devices 3, 3. This transmission case 14 is fixedly connected to the horizontal transmission case 13 and has a first case part 14A in a vertical position, and an L-shaped second case part 14A that is rotatable around a vertical axis _P1 with respect to the first case part 14A. 2
A case part 14B, an L-shaped third case part 14C that can be expanded and contracted and fixed to the horizontal case part of the second case part 14B, and this third case part 14C.
is divided into a fourth case part 14D which is rotatable about another vertical axis _P2 with respect to the vertical case part and is fixedly connected to the forced raking device 11, and The lower end of the device 11 is configured to be replaceable and fixed to the divider support rods 8A, 8B, 8C, and the forced raking device 11 is connected to both upper and lower axes P ₁ of the transmission case 14. , _P2 , the central part between the parallel lifting devices 3, 3 and the parallel lifting devices 3,
It is configured so that it can be freely switched and fixed in three positions with respect to both lateral outer portions of No. 3.
