Description

[Detailed description of the invention] The present invention has a plurality of weeding tool support rods arranged side by side in the horizontal direction to form a stem rod introduction path between the adjacent weeding tool support rods, and This invention relates to a reaping frame structure of a reaper in which a reaping device is installed over a grass tool support rod, and a pair of left and right star wheels are provided to merge the stem rods introduced into the adjacent stem rod introducing path into the center and convey them rearward. .

In the conventional reaping frame structure of a reaper, the rear ends of the weed trimmer support rods are connected by a laterally long large case, and a support shaft that forms the rotation axis of the star wheel is provided upright on this case. The problem that the present invention aims to solve is that the conventional structure is heavy in terms of weight, and the mud and straw debris attached to the base of the reaping stem are on the conveyance path of the star foil. The problem is that it is easy to accumulate, which disturbs the conveyance posture of the stem rods and causes conveyance resistance.The aim is therefore to use a simple structure to reduce the weight while also improving the combined conveyance of the stem rods.

The structural features of the idea devised to solve the problem are that, in the reaping frame structure of the reaper, there is a main frame in a horizontal position, and a horizontal main frame installed in parallel at the front of the main frame to attach the reaping device. The mounting frame in the suspended position is connected to the left and right support frames that respectively support the spindle that forms the rotation axis of the star wheel, and the weeding tool support is located in the center of the adjacent stem rod introducing path. The rear ends of the rods are connected to the mounting frame, and the rear ends of the other weeding implement support rods are bridged over and connected to the mounting frame and the main frame.

With the above characteristic configuration, the present invention provides the following effects. That is, since the weeding implement support rod, the main frame, the reaping device attachment frame, and the support frame were assembled in a grid pattern as a whole, a lightweight yet strong reaping frame was obtained.

In particular, as is clear from FIGS. 3 and 5 of the embodiment drawings, which will be described later, in the configuration of the present invention, a weeding tool support rod is provided below the stem-rod confluence formed by a pair of left and right star foils. Therefore, mud and straw debris carried by the base of the reaping stalk can be discharged downward, and unnecessary resistance is not exerted on the conveying stalk. Moreover, because a part of the weeding tool support rod is short, it is even lighter, and the overall strength is maintained sufficiently by rationally using the originally necessary support frame of the star foil. There is.

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

Fig. 1 shows a side view of the front part of a combine as an example of a reaping machine, and Fig. 2 shows its schematic plane. 3A, 3B, and a stem and rod conveying section 3C is supported via a swinging frame 4 which also serves as a transmission case and is capable of vertically swinging around the horizontal axis X at the rear end. There is.

The stem and culm conveying section 3C, as described later, joins the stems of rice, wheat, etc. that have been separately harvested by the pair of left and right reaping sections 3A and 3B, and conveys them to the feed chain 5 of the threshing device 2. Corresponding to the left reaping section 3A, a device 6 for clamping and conveying the base of the stem stem toward the confluence section A and a device 7 for locking and conveying the tip of the stem culm are provided; Corresponding to the reaping section 3B, a stem culm stock clamping and conveying device 8 and a stem culm tip locking and conveying device 9 are provided.
In order to convey the stalks from the grain to the threshing device 2, the left and right stalk tip locking and conveying devices 9 are extended rearward, and a stock clamping and conveying device 10 is provided, and,
An auxiliary clamping and conveying device 11 is provided for transferring stock from this conveying device 10 to the starting end of the feed chain 5. The stock holding and conveying device 10 is configured to be able to swing around a fulcrum P at its starting end so as to be displaced downwardly toward the outside in order to adjust the handling depth.

The left and right reaping processing units 3A and 3B are configured in the same way, and only the left one 3A will be described below. Three weeding tools 12a, 12b, 12c are arranged side by side at appropriate intervals in the lateral direction; A clipper-type reaping device 13 in a horizontal position that cuts the base of stems introduced into the pair of left and right stem introduction paths Da and Db formed between these weeding tools 12a...
Star wheels 14a and 14b are provided as a pair of left and right raking devices for raking the reaped stalks from the left and right paths Da and Db rearward and inwardly, respectively, to merge them. In the figure, 15a and 15b are a pair of left and right stem and rod lifting devices.

Further, the reaping section 3A equipped with these various devices is located behind the reaping section 3A, and is connected and supported to a main frame 16 in a horizontal posture attached to the free end of the swing frame 4. The frame structure will be explained below based on FIGS. 3 and 4. From the main frame 16 toward the front, the pair of star foils 14a, 1
A pair of left and right frames 17a, 1 supporting each of 4b.
7b is extended, and a frame 18 in a horizontal position supporting the reaping device 13 is attached to each of the extending ends of these frames 17a, 17b, and one of the three weeding tools 12a... Those at both side ends 12
Weeding tool support rods 19a and 19b extending in the front-rear direction and supporting the weeding tools 19a and 12c are attached to the main frame 16 and the horizontal frame body 18 and extend forward, and the horizontal intermediate part 12b is The weeding tool support rod 19b along the front-rear direction to support the horizontal frame 1
8 and extends forward.

Incidentally, although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
