Abstract

PURPOSE:To support a longitudinally extending grass-dividing apparatus in sufficiently high strength without using lateral reinforcing member by attaching a reel frame and a grass-dividing apparatus to a reaping part in a specific state. CONSTITUTION:A rotary rake-in reel 2 is attached to a reaping frame 7 of a reaping part A through right and left reel frames 2a. A grass-dividing apparatus l extending in longitudinal direction is supported by a supporting frame 11. The frame 11 is supported on a reel frame in a state to allow the relative vertical motion while restricting the relative lateral motion. The supporting strength in lateral direction can be increased by this structure.

In the structure in which the whole stems are sent from the plant base to the threshing device as in the above-mentioned prior art, it is not necessary to align the stems in a predetermined posture in the mowing part like a self-removing combine. Instead, simply cut and send to the thresher. In other words, it is relatively rough in terms of pretreatment in the mowing section, and a fixed type of weeding device that separates the culm to be cut and the uncut culm was sufficient. However, due to the speeding up in recent years due to improvement in work efficiency, the weeding action may not be sufficient in some cases, such as when harvesting lodging stem culms or at high-speed harvesting work. Like the all culm throw-in type combine combine shown in Japanese Utility Model Laid-Open No. 3-54131 that follows the partial structure, the vertical type vegetation such as a vertical turning structure that drives the claws protruding toward the front upward It has come to be considered to attach a device. An object of the present invention is to support the above-mentioned vertically long type weeding device in a cutting reel mounting type reaping unit with sufficient strength so that it can be reasonably attached.

In the take-up reel mounting type cutting unit, since the cutting unit main body supporting the cutting device, the lateral feeding auger and the like is at a relatively low position when viewed as a cutting unit, the cutting unit main body is separated from the weeding frame. Due to the support structure such as projecting, the lower part of the vertically long type weeding device can be easily supported, but regarding the upper part of the weeding device support, there is a reel frame corresponding to the member on the cutting unit body side nearby. is doing. Therefore,
As shown in FIG. 1, the weeding device 1 is supported by the upper and lower connecting members 9 and 10 to obtain the supporting strength in the front-rear direction, and the supporting strength in the left-right direction is obtained using the reel frame 2a. . However, the reel frame 2a normally swings up and down around the fulcrum Z at the rear part thereof to move the take-up reel 2 up and down, and cannot be simply supported. Therefore, the left and right side walls 20a and 20b of the frame body 20 attached to the rear part of the weeding device 1 and the reel frame 2a
With the structure in which the bearing 22 at the tip is fitted, relative vertical movement is permitted, and relative horizontal movement is regulated, the weeding device 1 can be moved in the horizontal direction while the vertical movement of the take-in reel 2 can be performed without hindrance. It will be able to support enough strength.
