Description

[Detailed description of the invention] The present invention relates to an improvement of the machine frame structure of a threshing device.
Its purpose is to provide a blade mounting frame that is inherently robust in order to securely support the straw cutting blade that protrudes into the handling chamber against the cutting reaction force, and a straw removal conveyor at the rear of the threshing section. By making effective use of the frame-shaped frame, which is inherently strong because it is provided so that the middle part of the frame can be inserted through it, and it also serves as the attachment part for heavy waste straw processing equipment such as waste straw cutters. Although the overall structure is simple, the overall strength of the machine frame can be significantly improved.

First, an embodiment of the machine frame structure of a thresher according to the present invention will be described based on illustrative drawings.

3 in the figure shows a plurality of straw cutting blades 2 in the axial direction of the handling cylinder, which are located protruding into the handling chamber 1 in which the rotating handling cylinder 8 is housed in the shaft frame.
This is a blade mounting frame for fixedly supporting the blades, and is installed across the front and rear side plates 10A, 10A of the handling chamber 1 at a position facing the handling opening 9. 5
The intermediate portion of a device 4 for pinching and conveying the waste straw from the handling chamber 1 diagonally rearward is inserted into the rear of the threshing section, and the device is arranged to allow the conveyance device 4 to pass the waste straw to the rear. This is a frame-like frame that also serves as a mounting frame for the waste straw processing device 11 (cutters, etc.). 6 is a pair of support rods 7 that insert the grain collection bag 12 and suspend and support it;
This is a round pipe-shaped mounting member that supports the blade mounting frame 3 in a cantilever manner, and is arranged to connect the rear end of the blade mounting frame 3 and the frame-like frame 5 with strength. Furthermore, this support rod attachment member 6 for strength connection is not directly connected to the blade attachment frame 3, but is attached to the attachment stay 13 of the No. 1 screw tube 14 fixed to the blade attachment frame 3.
It is connected to.

Further, 15 is a feed chain suspended along the handling port 9, 16 is a sorting section disposed from the lower part of the handling chamber 9 to the lower part of the conveying device 4, and 17 is a feed chain that is hung along the handling port 9; The first item collected at the bottom of the sorting section 16 is transferred to the first item screw cylinder 1.
18 is a screw conveying to the lower part of 4,
A screw conveys the second collected material to the return thrower 19 to the handling room 1, 20 is a winnowing machine for generating sorting air, and 21 is a dust blower.

The threshing device configured as described above is mainly used as a threshing device mounted on a combine harvester or a harvester, but it can also be used as a stationary threshing device.

In summary, the machine frame structure of the threshing device according to the present invention includes a blade mounting frame 3 for fixedly supporting the straw cutting blade 2 protruding into the handling chamber 1, and an intermediate portion of the straw removal conveying device 4 behind the threshing section. The frame-shaped frame 5 is inserted into the frame-shaped frame 5, and the attachment member 6 of the grain collection bag support rod 7 and the blade attachment frame 3 are attached to the frame-shaped frame 5 side.
Mounting stay 13 of the No. 1 screw tube fixed to
They are characterized by being interconnected by connecting them.

That is, in order to connect the blade attachment frame 3 and the frame-like frame 5, the attachment member 6 of the grain collection bag support frame 7 and the attachment stay 13 of the No. 1 screw cylinder 14 are inherently provided in the threshing device. Since these two members, which are both strong and durable, are used and connected to each other, the structure is simple without using any special members, and the strength of the machine frame is improved. There are advantages that can be achieved.
