Description

[Detailed description of the invention] In the present invention, a threshing section and a threshed grain tank are arranged side by side in the width direction of the machine body, and a waste straw shredding and discharging device is connected to the rear side of the threshing section. A shredding discharge device is installed so as to protrude from one side of the threshing section toward the threshed grain tank, and a space is provided between the front surface of the protruding waste straw shredded discharge device and the rear surface of the threshed grain tank. , and a grain thrower for taking out grain from the threshing grain tank is provided within this interval, and the grain thrower is further provided with an opening facing the rear side of the machine body and a lid body that covers this opening,
and the lid body is provided with an air intake port,
A dustproof wall is erected between the waste straw shredding discharge device and the fried grain thrower, and the swallow is opened to facilitate cleaning and inspection, and the fried grain is smoothly blown by air from the thrower. The present invention also relates to a combine harvester configured to be able to perform the operation while suppressing grain damage, and to suppress dust suction by the thrower.

In the combine harvester mentioned above, conventionally, in order to prevent dust such as waste straw released in large quantities from the waste straw shredding discharge device from being sucked into the grain thrower, the dust-proof wall is installed to the extent that it does not affect the suction of the thrower. Since it is installed upright close to the thrower, when inspecting or cleaning the thrower, you have to insert your hand from the outside side of the machine into the narrow gap between the thrower and the dust-proof wall.
At the same time as attaching and detaching the lid, the inside of the thrower had to be worked on, which made it difficult to reach the part of the thrower located inside the machine body, making the work time consuming and difficult.

Also, by widening the distance between the thrower and the dustproof wall,
If it was made easier to reach the inner part of the thrower, dust would be more likely to be sucked into the thrower through the wider gap, resulting in a lower dustproofing effect.

The purpose of the present invention is to enable work on the thrower to be performed easily and quickly without reducing the tank capacity or reducing the dust absorption prevention effect.

A characteristic configuration of the present invention is that, in the above-described combine harvester, the dustproof wall at a position facing the opening of the grain thrower is provided with an opening cut out so that the grain thrower faces outward from the machine body; This opening is provided with a lid that can be opened and closed freely.

That is, by providing the opening in the dust-proof wall, it is possible to easily reach a portion of the thrower located inside the fuselage from outside the fuselage through the opening. Therefore, the attachment and detachment of the lid at the thrower opening and the work performed by inserting tools and cleaning tools into the thrower can be performed easily and quickly, and inspection and cleaning work can be performed efficiently.

Moreover, unlike conventional methods, there is no need to widen the gap between the thrower and the dust-proof wall; instead, the distance can be narrowed to the extent that the thrower does not restrict air intake, improving the dust-proofing effect.Furthermore, the opening in the dust-proof wall can be opened and closed. By providing a freely movable lid, the opening can be closed to prevent dust, especially dust from the waste straw shredding device, from entering the thrower side under normal conditions. Could be obtained as well as a dust wall.

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

As shown in Fig. 1, a reaping section 1 that raises the planted grain culm, reaps it, and conveys the reaped grain culm to the rear.
is connected to a crawler-type traveling machine body having a driving part 2, a driving part 3, a threshing part 4, a device 5 for shredding and discharging threshed waste straw, a threshed grain tank 6, etc., to constitute a combine harvester.

The threshed grain tank 6 (hereinafter referred to as tank 6)
Inside the tank 6 is an internal grain delivery screw 7, and a frying thrower 8 for the grains from the screw 7 and a thrower cylinder 9 for guiding the grains from the thrower 8 to a predetermined take-out location. It is located at the rear.

Furthermore, to describe in detail the arrangement of the threshing section 4, waste straw shredding device 5, tank 6, and grain thrower 8 (hereinafter referred to as thrower 8), the threshing section 4 and tank 6 are arranged in the width direction of the machine body. A waste straw shredding discharge device 5 is arranged in parallel to the rear side of the threshing section 4, and the waste straw shredding discharge device is installed so as to protrude from one side of the threshing section 4 to the tank 6 side. ,
A space is provided between the front surface of the waste straw shredding discharge device 5 in a protruding state and the rear surface of the tank 6, and a thrower 8 for taking out grains from the tank 6 is provided within this space. .

To configure the drive system of the take-out screw 7 and the thrower 8, the rotating body 8a of the thrower 8 is attached to the take-out screw 7 so as to be able to rotate integrally with the take-out screw 7, and as shown in FIG. The transmission 11 for the traveling device 10 and the threshing section 4 are interlocked with the engine 12 in parallel with each other, and between the unloading screw 7 and the engine 12, between the threshing section 4 and the engine 12, and
A belt-type clutch 13 is provided between the reaping traveling transmission 11 and the engine 12, or a transmission 14 is provided in which the carrying-out screw 7 and the threshing section 4 are linked in parallel, as shown in FIG.
and the reaping traveling transmission 11 are connected to the engine 12 in parallel, and the unloading screw 7
between the threshing section 4 and the transmission 14, and the reaping traveling transmission 11.
belt type clutch 1 between the engine 12 and the engine 12.
3 is provided so that grain can be taken out from the tank 6 even when the threshing section 4, the reaping section 1 and the traveling device 10 are all stopped.

As shown in FIGS. 2 and 3, the thrower 8 has an opening 15 facing the rear side of the aircraft, and this opening 1
A removable lid 16 for the thrower 8 is provided, and the lid 16 is provided with an intake port 17 with a dustproof mesh, and a dustproof wall 1 for suppressing dust intake from the thrower 8 is provided.
8 is attached to the tank 6 and the strut 19 of the waste straw shredding discharge device 5, and is erected between the waste straw shredding discharge device 5 located on the rear side of the thrower 8 and the thrower 8. In addition, the dustproof wall 18 at a position facing the opening 15 of the thrower 8 has an opening 20 cut out so that the thrower 8 faces outward from the aircraft body, and a rubber plate that allows the opening 20 to be opened and closed freely. Further, the rubber plate lid 21 is fixed only on the upper end side of the opening 20 so as to close the opening 21 in a natural state, and the rubber plate lid 21 is turned over. When raised, the opening 20 opens and the thrower 8 is exposed to the outside, and the grain frying by the thrower 8 is performed by both the throwing and blowing of air by the rotating body 8a. Compose and thrower 8
