Description

[Detailed description of the invention] The present invention provides a threshing section above the sorting section with its feed chain attachment section being an over-knob, and a rotating shaft of the sorting section that protrudes toward the feed chain side. The present invention relates to a transmission structure of a threshing sorting device in which grains and a feed chain are interlocked and connected by a winding transmission device.

In the above structure, conventionally, as shown in FIG. 6, a transmission case 34 to the feed chain 3 is attached to the feed chain attachment part of the threshing part that overhangs the sorting part, and the transmission case 34 is connected to the feed chain 3. It was configured to transmit driving force by wrapping a transmission belt around the input wheel 28 to the feed chain projecting laterally outwardly and the wheel of the rotating shaft 26 projecting from the threshing section. Therefore, the rotating shaft 26 from the threshing section has to protrude further outward than the part that overlaps the sorting section, which requires considerable shaft strength and is not economically viable. It was a disadvantage.

In view of these circumstances, the present invention aims to shorten the protruding length of the rotary shaft from the threshing section through simple improvements.

Embodiments of the present invention will be described in detail below with reference to the drawings.

A reaping section 2 is provided at the front of the machine body equipped with a crawler-type traveling device 1 to raise, reap and transport the planted husks, and in the center of the machine body, in cooperation with a feed chain 3, the threshing process is performed. The combine harvester is equipped with a threshing sorting device 4 for sorting threshed grains and conveying them to a bagging section 5, and a shredding device 7 for shredding the threshing section straw at the rear of the machine body.

As shown in FIG. 2, the threshing and sorting device 4 is located below the threshing section 5, which consists of a handling chamber in which a handling cylinder 8 having handling teeth is installed and a processing chamber in which a processing cylinder 9 is installed. A sorting section 6 is provided which is composed of a movable swinging sorting plate 10 and a wind sorting device 11, and further below there is a screw conveyor 12 for discharging the first threshing material and a screw for discharging the second material such as paddy with branches. A conveyor 13 is provided, which is configured to shake and sort the threshed material from the threshing section 5 and perform wind sorting, and discharges and conveys the sorted paddy as threshing and flavorings to the outside of the threshing sorting section 4,
This is configured to be transported to the bagging section by a lifting screw conveyor 14.

The second threshing material is carried out by a screw conveyor 13 for discharging second threshing products, and the second threshing material is transported to a processing chamber by a thrower 15 driven by this conveyor shaft for reprocessing. .

Next, the driving force transmission structure of the threshing sorting section 4 will be explained.

Driving force is to be transmitted from a rotating shaft 1γ driven by an engine 16 to a shaft 18 of the handling cylinder 8 and a shaft 19 of the processing cylinder 9 through a first transmission belt 20 via a bevel gear mechanism.

The rotating shaft 17 and the driving shaft 21 of the swinging sorting plate 10 are interlocked by a second transmission belt 22, and the swinging sorting plate drive shaft 21, the winnowing drive shaft 23 of the wind selection device 11, and the The drive shafts 24 of the material lifting screw conveyor 14 are interlocked and connected by a third transmission belt 25 wound over these three parts, and the oscillating sorting plate drive shaft 21 and the first material discharging screw conveyor 12 are connected together. The drive shaft 26, the screw conveyor 13 (7) for discharging and transporting the two aromatic substances, the drive shaft 27, and the drive shaft 28 of the feed chain 3 are interlocked and connected by a fourth transmission belt 29 wound over these four parts, One tension pulley 30 is attached to each of the second to fourth transmission belts 22, 25, 29.

Furthermore, the feed chain drive shaft 28 and the drive shaft 31 of the threshing section straw shredding device 7 are connected to one tension pulley 32.
They are interlocked and connected by a fifth transmission belt 33 provided with.

The structure for transmitting the driving force to the feed chain drive shaft 28 will be explained.

As shown in FIG. 5, the threshing and sorting section 4 has an over-knob structure in which the threshing section 5 projects further toward the feed chain 3 than the sorting section 6 when viewed from the front.

A transmission case 34 containing a built-in speed reducer is attached to this overbung location, and an idler wheel 35 for winding the feed chain, a chain guide, etc. are attached, and the feed chain 3 is attached.

As shown in the drawing, the transmission case 34 is extended below the overhanging part, and the feed chain drive shaft 28 is pivotally supported at this extension part, and the transmission case 34 is extended below the overhanging part. , an input wheel body 36 is attached to the drive shaft 28 portion on the inner surface of the transmission case between the transmission case 34 and the side wall of the threshing section 5, and the driving force is transmitted from the fourth transmission bell 29+C as described above. It is structured as best as possible.

By providing the input wheel 36 below the overlapping part, the shaft 21 protrudes from the sorting section 6.
, 26, 27 and the rotating shaft 17 from the bearing portion are shortened to increase the strength of these shafts.

Incidentally, the winding power transmission device 29 may be a chain instead of a belt.

The above are examples of the present invention.

As shown in this example, the structural features of the present invention are:
In the transmission structure of the threshing and sorting device described at the beginning of the detailed description, the transmission case 3 is connected to the feed chain 3.
4 is attached to the overhanging mounting part and extends downward, and the winding member 36 for winding the transmission tool 29 is attached to the transmission case 34 below the mounting part. It is pivotally supported on the inner surface of the transmission case 34, which is between the side wall of the threshing section 5 and the side wall of the threshing section 5.

Effects due to the configuration of this invention.

By attaching the wheel 36 for the feed chain to the inner surface of the transmission case 34 below the feed chain attachment part, the rotating shaft 26, which is linked via the wheel 36 and the winding transmission 29, can be used for threshing sorting. The length of the protrusion from the device 4 can be shortened, and the required strength of the rotating shaft 26 can be reduced, resulting in an inexpensive configuration.
