Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-throwing thresher which is mainly mounted on a combine.

[0002]

2. Description of the Related Art Conventionally, Japanese Utility Model Laid-Open No. 1-167839.
Japanese Utility Model Publication No. Sho 55-162533 or Japanese Unexamined Patent Publication No. Sho 63-
There was a thresher found in Japanese Patent No. 84419. However, all of these prior arts have a structure in which the chain frame in which Fidothien is incorporated is rotated back and forth or up and down with respect to the handle of the thresher.

[0003]

In the prior art,
In both cases, when the threshing culm is packed in the handling room during threshing and the grain stalks being transferred are taken out in order to move the chain frame in the direction intersecting the running direction of the feed chain, the grain culm is removed from the handling room. There is a problem that the opening of the handle cannot be made smooth due to the pulling action.

[0004]

According to the present invention, a gripping rod 8 is provided above the outside of the handle opening 7 so as to rotate upward together with a part of the outer wall of the handling chamber 2. It is possible to move the chain frame body 10 in which a feed chain 11 for sandwiching and transferring the root side of a grain cullet that engages with the pinching rods 8 is sandwiched below the outside of the mouth side, along the handle side. The threshing machine is characterized in that the handle 7 is provided so that it can be opened and closed.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front sectional view of a thresher, in which 1 is a handling barrel, 2 is a handling chamber, 3 is a handling net, 4 is a first handling chamber frame that forms a part of the handling chamber, and 5 is described later. It is the second handling room frame to which the clamping rod of is attached. The second handling chamber frame 5 is pivotally attached 6 to the first handling chamber frame 4 and is attached so as to be rotatable upward. Reference numeral 7 indicates a handle. Reference numeral 8 denotes a sandwiching rod, which is attached to the second handling chamber frame 2 via a bracket. Reference numeral 9 denotes a spring that lowers the pinching rod 8.

Reference numeral 10 is a chain frame body in which a feed chain 11 is wound and supported via a sprocket, and also serves as a chain cover. Reference numeral 12 denotes a drive shaft, which is provided on the main body side of the thresher and is appropriately rotated by transmission. Reference numeral 13 is a drive gear. Reference numeral 14 is a chain transmission shaft on the side of the chain frame, which is provided with a driven gear 15 which meshes with the drive gear 13.

Numerals 16 and 17 are rails which are provided on the outside of the handling mouth on the side of the threshing machine main body in the direction along the handling mouth. 18 and 19 are rotatably supported by the chain frame body 10 and are supported by the rails 16 and 17 so that the chain frame body 10 can be rolled. Two
Reference numeral 0 denotes a sorting chamber, and reference numerals 21 and 22 denote knobs integrated with the set bolt of the chain frame body 10. According to the above embodiment, when the handling net 3 is attached or detached or the inside of the handling room 2 is cleaned,
The second handling chamber frame 5 is swung upward and swung up, the knobs 21 and 22 are turned to remove the set bolt, and the chain frame 10 is moved along the rails 16 and 17 in a manner of moving the sliding door. It is advisable to open the handle 7 by moving the handle 7 in the direction of the arrow (a).

At this time, since the chain frame 10 is moved in the traveling direction of the Fidochien 11, even if it is stopped during the threshing work to open the handle 7, it is possible to unexpectedly drop the grain culm. The situation is unlikely to occur, and the chain frame body 10 can be smoothly moved at the time of opening. When the chain frame 10 is moved, the power of the hood 11 is simultaneously transmitted by automatic engagement and disengagement of the gears 13, 15.

As shown in FIGS. 3 and 4, as a technical means for moving the chain frame 10 downward, it is supported by cross type link rods 23 and 24, and one of the link rods 2 is supported.
If 4 is supported by the fluid pressure cylinder 25, the chain frame 10 can be easily moved up and down by switching the fluid operation in the cylinder, and the opening of the handle 7 can be facilitated. Symbols 26 and 27 in the figure are elongated holes in which the link pin is freely moved.

In the conventional technical means of rotating the feed chain frame 10 via the vertical support shaft, except for the case where the feed chain frame 10 is opened by rotating it up to a right angle position with respect to the thresher frame. There is a problem in that the chain frame can be opened only in a wedge shape in plan view, and the chain frame 10 becomes an obstacle. To improve this, the structure shown in FIG. 5 may be used. This FIG. 5 shows a plan view of the main part, in which the machine frame on the main body side of the threshing machine is provided with the first support shaft 28 in the vertical direction, and the tip side of the arm 29 rotatably attached thereto. When the side of the chain frame body 10 is pivotally mounted on the second support shaft 30 to open the handle 7, the chain frame body 10 can be rotated at both fulcrums of the support shafts 28 and 30. If the whole of the chain frame 10 is separated from the handle 7 by the rotation range of the arm 29, the rotation of the prior art is further added to further widen the handle portion. It can be opened.

With the technical means for rotating the feeder chain 11 side or moving it in the front-rear direction to clean the inside of the handling chamber 2, it may be difficult to perform reliable cleaning. Therefore, as seen in Japanese Utility Model Laid-Open No. 2-46527, there is a technical means for opening the handling chamber by rotating both the upper frame portion of the handling barrel chamber and the handling barrel upward. However, with the opening technology using a simple turning means, the side opposite to the handle cannot be opened sufficiently,
There was a problem that it could not be cleaned sufficiently. Therefore,
In order to eliminate this, as shown in FIG. 6, the upper and lower link rods 3 having the base side pivotally attached to the main body frame 34 of the thresher.
The upper frame 33 of the handling chamber 2 in which the support shaft 1a of the handling barrel 1 is integrally provided with 1, 32 is attached, and the link rod is moved up and down by a lifting mechanism 35 such as a hydraulic device. In addition, the portion that pivotally supports the upper frame body 33 is interlocked with a support shaft moving mechanism such as a long hole 36 so that the substantial link dimension is shortened when the upper frame body 33 is raised. It is configured to rotate to the side.

[0012]

As described above, according to the present invention, the chain frame 10 carrying the feed chain 11 is moved back and forth in a sliding door-like manner in the direction along the handle 7 to open the handle. Therefore, it is possible to smoothly and easily open and close the handle, and even if the grain culm is stopped between the feed chain 11 and the pinching rod 8 during threshing work. It can be moved, and there is little need to drop the grain culm out of the plane.
