Description

[Detailed Description of the Invention] The present invention relates to a threshing device for mounting on a combine harvester, for self-propelled self-unloading, or for stationary use.

In the threshing device, the handling cylinder rotates inside, and the grain culm is fed through the feed chain from the handling port, so the handling teeth of the handling cylinder engage the grain culm inside, causing the handling chamber to expand outward. Power is at work.

In addition, since the handling opening is opened in an arc shape to match the length of the grain culm, it is not possible to reinforce and connect the handling trunk cover and handling trunk side plate on the feed chain side, so the side plate mentioned above in the handling room becomes weak. In particular, in top handling type threshing equipment, the handling chamber is located above the handling barrel, so the strength of the upper part of the handling chamber is further weakened.

In this invention, in order to increase the strength of the U-shaped part of the front or rear board of the handling chamber that surrounds the handling opening, the upper frame of the handling chamber is reinforced by constructing a frame made of pipe or the like. The lower part is connected to the input shaft casing and bearing body for driving the handling barrel, and the upper frame of the handling chamber and the handling barrel drive case are integrated as a whole.

This increases the rigidity of the entire frame structure by connecting the upper frame of the handling chamber and the handling barrel drive case.

The purpose of the present invention is as described above, and the structure of the present invention will be explained based on the structure of the embodiment shown in the attached drawings.

FIG. 1 is a perspective view of the rear plate of the handling chamber of the threshing device. FIG. 2 is a perspective view with the handling cylinder drive case 2 removed.
Figure 3 shows the upper frame of the handling room and the rear panel of the handling room removed. Figure 4 is a drawing of the front panel of the handling room. FIG. 5 is an exploded perspective view of the handling chamber side plate.

The handling chamber of the threshing device is made up of the front and rear plates 14, 14a of the handling chamber and the rear plate 6 of the handling chamber, the right side of the handling chamber 27, the left side of the handling chamber 21a, 21b, etc. on the left and right, and the upper surface is a handling chamber cover. It is closed with a sorting device etc. on the bottom side, and a bottom plate on the bottom side.

The threshing device has a top-handling device that threshes the grain on the top surface of a handling drum,
Although there is a lower threshing device in which the grain is threshed on the lower surface of the handling barrel, this embodiment particularly shows an upper threshing device.

In addition, there are cases in which the drive case 2 of the handling cylinder is provided on the front plate 14 of the handling chamber, and cases in which it is provided on the rear plate 6 of the handling chamber.
In this embodiment, a case will be described in which a handling barrel drive case is fixedly installed on the handling chamber rear plate 6.

However, a lower handling type may be used, or a case where the handling cylinder drive case may be fixed to the front plate of the handling chamber may be used.

First, the handling chamber front plate is made up of an integral handling chamber front plate (upper) 14 and a handling chamber front plate (lower) 14a which is the front plate of the sorting device section.

A U-shaped frame made up of a handling room upper frame 15 and a reinforcing frame 20 is fixedly installed from the right end of this handling room front plate (upper) 14 to form the upper part of the handling room.

In addition, a shellfish grain collecting plate 11 is projected rearward from the lower part of the rear plate 6 of the handling chamber, and the shellfish grains falling from the waste straw are returned to the sorting room. Further, from the right end, a U-shaped frame integrally comprising a handling chamber upper frame 8 and a reinforcing frame 19 is fixedly installed to constitute the upper part of the handling chamber.

A handling chamber cover is placed between the front and rear handling chamber upper frames 15 and 8 from above.

9 and 17 are attached to the left end of the upper frame of the handling room. This is a fixing device for the handling room cover.

Further, 18 in FIG. 4 is a rubber sag that covers the handling opening. Left and right side plates are attached to these handling chamber front plate 14 and rear plate 6. Handling room right side panel 27 in Figure 5
The front and rear reinforcement frames 20, 19 and the front panel of the handling room 1
4. It is fixed as a single plate to the right end of the rear plate 6.

On the other hand, the left side board of the handling room is the left side board of the handling room (top) 2.
It is divided into 1a and (bottom) 21b, and (top) 21
21b (bottom) constitutes the side plate of the sorting chamber.

A cutting blade 2 is provided on the left side panel (upper) 21a of the handling chamber.
An insertion plate 22 into which the cutting blade 1 is inserted is provided, and the cutting blade is configured to be fixed with a fixing plate 28 after insertion.

Further, dust feeding valves 25, 25 are pivotally supported on the right side panel 27 of the handling chamber, and the dust feeding valve 2 is operated by a dust feeding valve lever 26.
By adjusting 5 and 25, the amount of dust sent can be adjusted. 23 and 24 are crimp net mounting frames, and 30 is a crimp net.

In this overall configuration, the present invention has the following features:
This relates to the configuration of the handling chamber upper frame 8 of the handling chamber rear plate 6 and the handling chamber drive case 2.

A V-pulley is fixed to the right side of the handling cylinder drive shaft 5, and power is transmitted from the engine to the pulley.

7 is a bearing body of the handling cylinder drive shaft 5;
A casing 16 is interposed between the casing 16 and the handling barrel drive case 2, and an L-shaped mounting plate 31 is mounted between the casing 16 and the mounting plate 10 of the reinforcing frame 19.

The upper frame 8 of the handling chamber is bent into a shape, extends below the handling opening, and is integrated with the handling barrel drive case. 6a is a passage hole for the handling barrel shaft.

The bevel gear in the handling cylinder drive case 2 rotates the handling cylinder shaft 1, the pinion on the handling cylinder shaft 1 and the rack of the feed chain shaft 3 are rotated, and the sprocket 4 is rotated.
is driving.

Reference numeral 2a denotes a mounting portion of the handling barrel drive case 2, which is fixed to the handling chamber rear plate 6. 12 is the second reduction port.

Since the present invention is constructed as described above, the insufficient strength of the upper part of the handling port is reinforced by extending the handling chamber upper frame 8 from the handling barrel drive case part, thereby increasing the strength.

In addition, the handling chamber rear plate 6 made of a pressed iron plate is reinforced with a U-shaped frame that integrates the handling chamber upper frame and the handling barrel drive case 2, thereby improving the mounting strength of the handling barrel drive case. However, sufficient strength can be provided even if the handling cylinder drive case is bent due to overload of the handling cylinder.
