Description

[Detailed description of the invention] The present invention includes a main pulling device that moves the stem culm locking and lifting claw rearward and diagonally upward on one side of the stem culm pulling introduction path, and also An auxiliary lifting device that locks and conveys the culm tip side is provided above the main lifting device, and a claw tip movement trajectory of the lifting claw of the main pulling device is provided on the other side of the culm lifting introduction path. Regarding the structure of the pre-treatment section of the reaper, which has a guide member placed nearby and a dividing rod that divides the non-reapable stem culms outward from the side of the machine, it is possible to achieve good division even with an extremely simple modification. The purpose is to enable weeding and raising, and to reduce costs by reducing the number of parts for this purpose.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

When viewed from the side, a driving wheel 1 is provided at one location in the longitudinal direction, and a sled-like grounding body 2 is provided at the front of the machine.The stem culm locking claw 3...is directed diagonally upward at the rear of the machine. The main lifting device 4 to be moved, and the guide member 5 along the claw tip trajectory of the lifting claw 3...
are arranged in a distributed manner with respect to the stem culm pulling path A, and the tip side of the stem culm to be lifted is locked at the rear half of the lifting path of the main pulling device 4 and at the upper part of the main lifting device 4. An auxiliary pulling device 6 for conveyance is provided, and a weeding rod 7 for weeding the non-reaping target culms outward to the side of the machine is provided near the guide member 5,
Then, a clipper-type reaping device 8 is installed in a state where it crosses the stem culm pulling path A, and a substantially constant amount of the cut stem culms is tied together and transferred to the already mown field opposite to the dividing rod 7. A device 9 for discharging the harvester is provided, and a driving unit 10 and a control unit 11 are arranged at the rear of the machine body to constitute a binder, which is an example of a reaper for reaping and binding planted stem culms.

As shown in FIG. 2, the weeding rod 7 has an inclined portion a that gradually pushes the non-reaping stem culm toward the outside of the machine body in a state of weeding action on the non-reaping stem culm, and a slanted portion a connected to the inclined portion a that gradually pushes the non-reapable stem culm toward the outside of the machine body. It consists of a straight line portion b approximately parallel to the guide member 5, mounting rod portions c, c of the guide member 5 to the support member 12, and a connecting rod portion d spanning the straight line portion b and the rear side mounting rod portion c, and , the mounting rod portion c,
a concentric cylindrical member 13 attached to the support member 12,
13 so as to be rotatable.

A fan-shaped member 14 having radial engagement recesses e formed at appropriate intervals on its circumferential surface is fixed to the upper side of the upper one of the cylindrical members 13, 13,
A locking member 15 that can be selectively engaged and detached from the recess e is attached to the connecting rod portion d while being biased in the engagement direction by a spring 16, and
A grip 17 for disengaging the engaging member 15 against the biasing force of the spring 16 is connected to the engaging member 15, and as shown in FIGS. The dividing rod 7 is configured to be rotatable and fixed around its attachment rod portions c, c.

That is, as shown in Fig. 4A, by locating the straight part b of the dividing rod 7 near the base of the stem culm that is not to be harvested, a mid-split structure can be used to eliminate the trampling of the stem culm. As shown in Figure B, by positioning the divider rod 7 on the outside of the machine body, the stem culm that is leaning toward the main pulling device 4 can be pushed out to the outside of the machine body and harvested. By positioning the dividing rod 7 in an almost upright position, as shown in Figure C, we can perform cutting operations that do not cause shedding of untargeted stem culms, and by positioning the dividing rod 7 in an almost upright position, unnecessary cutting can be performed on stem culms that are almost upright. Perform the mowing work without causing any weed cutting, and then switch the weeding rod 7 to a position where it follows the trajectory of the claw tip of the stem culm locking claw 6a of the auxiliary pulling device 6, as shown in Figure D. This makes it possible to perform a reaping operation that prevents the tip of the stem culm, which is leaning toward the side opposite to the main lifting device 4, from coming off the stem culm locking claw 6a.

In addition, as shown in FIG. 4B, the dividing rod 7 is
It is only necessary to provide it so that it can be freely switched between at least two states: a state in which it protrudes outward to the side of the body, and a state in which it is caused to follow near the movement trajectory of the tip of the stalk culm locking claw of the auxiliary pulling device 6, as shown in FIG. Furthermore, the present invention may be installed in a harvester such as a combine harvester.

In summary, the present invention, in the above-mentioned structure of the pre-processing section of the reaper, has a state in which the weeding rod 7 protrudes outward from the side of the machine body, and a state in which the auxiliary pulling device 6 moves near the tip of the stem culm locking claw. It is characterized in that it is provided so that it can be freely switched between the state in accordance with the

In other words, if the planted stem culm is a little lying down toward the main pulling device 4 side, the tip of the planted stem culm does not come out from the auxiliary lifting device 6, and the stem culm that is not to be harvested is moved to the outside of the machine. It is necessary to weed, and conversely,
If the planted stem culm is slightly lodging on the opposite side from the main pulling device 4, it is not necessary to divide the stem culm that is not to be harvested, and the tip side of the planted stem culm can be removed from the auxiliary lifting device 6. In this point, it is necessary to prevent
In other words, depending on the lodging condition of the planted stem culm, a state that requires weeding action on the planted stem culm and a state that requires raising and preventing the tip of the planted stem culm from coming off may occur, and these conditions may occur at the same time. Focusing on the points that do not
This is a device that can be freely switched to function as a device to prevent the stalk from coming off on the stem, culm, and tip side by pulling up one dividing rod 7. Costs can be reduced by reducing the number of parts by having a structure that also functions as a device to prevent the stem from coming off. I am now able to achieve this.
