Description

[Detailed description of the invention] A tank section is provided that spans over the threshing section mounted on the machine base and over the grain take-out section attached to the side thereof, and one side of the tank section is pivoted to the grain take-out section. When communicating with both, it is desirable to surround the communication part between the two with an expandable material such as a bellows body or canvas so that the grains do not flow out of the machine from the communication part when the tank part is raised.

However, if the expansion material is simply stretched around the communication part, the expansion material will fold inward when the tank part is brought into close contact with the grain removal part, and the grains will flow down and cause severe wear. The problem is that the grains get caught in the folds and break.

The present invention is a combine harvester equipped with an expansion/contraction material that does not obstruct the extraction of grain, reliably prevents it from flowing out of the machine, and is extremely unlikely to be worn out or damaged. A grain tank is provided, in which a tank part is provided that spans over the threshing part mounted on the machine base and over the grain take-out part attached to the side thereof, and one side of the tank part is used to store the grains. When connected to the upper part of the take-out part, both are pivotally supported so as to be tiltable, and downward-facing storage bodies are provided on both sides of the part of the tank part communicating with the grain take-out part that continues at least to the supported part, and this storage An expanding/contracting material is provided between the body and the grain removal section to surround the communicating portion and the grain lifting tube.

The embodiment shown in the drawings will be described below. Reference numeral 1 denotes a threshing unit mounted on one side of a machine base 3 having a traveling device 2, and a grain lifting cylinder 4 on the other side of the upper part, which protrudes from the machine type. A grain extraction section 7 supported by supported supports 6 and 6' is provided, and a tank section 8 provided over the upper surface of the grain extraction section 7 and the threshing section 1 is connected to a support shaft 10 and a bearing 9. ,9
It is rotatably supported by the supports 6 and 6' via the support members 6 and 6'.

The base of both the grain extraction part 7 and the tank part 8 is a grain cylinder 4.
Since it is supported by the support metal 6 protruding from the threshing device 1 and the support metal 6' protruding from the threshing device 1, and connected by the support shaft 10, the swing thrower 11 attached to the tank part 8 and the helical shaft 11b installed therein can be rotated. The lower end and the upper end of the grain lifting tube 4 and the helical shaft 4a installed therein can be reliably joined without turning.

The upper end of the shredded lifting cylinder 4 reaches the bottom plate 1 of the tank section 8, and the lower end of the rotating thrower 11 rotatably supported by a bowl-shaped support 10' provided on the bottom plate is connected to the lifting cylinder 4. A thrower that fits around the upper end of the grain cylinder 4, has blades 11a, and rotates the upper end.
A helical shaft 11b supported on the top plate of No. 11 via a bearing.
The lower end of the rotary thrower 11 is connected to the upper end of the helical shaft 4a in the grain lifting cylinder 4 with a ferrule. It rotates intermittently through gears.

Furthermore, hanging rods 13 for suspending the paddy bags 12, 12 are provided on the support frame 5 to protrude outward, and the four funnel-shaped take-out lowers a of the grain take-out section 7 are located below them. The paddy bag 12 is suspended from the paddy bag 12, and faces into the opened rice bag 12 through a flexible tube 14.

Reference numeral 15 denotes a hydraulic cylinder whose upper end is movably pivoted to the support frame 5, and its piston rod 15' is connected to the lower surface of the bottom plate of the tank section 8 via a tongue buckle 15.

The bottom plate of the tank portion 8 on the side of the support shaft 10 has an opening 8a for communicating the tank portion 8 with the grain removal portion 7, and a portion surrounding this opening 8a and the grain lifting tube 4 (see Fig. 3). A downward U-shaped storage body 16 is fixed to the portion indicated by reference numeral A in FIG. The upper end edge of the bellows-shaped expansion/contraction material 17 that surrounds the upper end of the grain lifting cylinder 4 is attached to the storage body 1 with a rubber seat 19 by a mount-shaped hook 18.
The auxiliary hopper 20 is attached to the bottom of the grain removal tube 6, and its lower edge surrounds the upper end of the grain removal section 7 and the outer circumference of the upper end of the grain lifting tube 4.
A hook 18 connects the rubber seat 1 to the area that spans the upper end.
It is attached together with 9.

In addition, in the drawing, 21.21a is an overflow opening/closing lid provided on the top plate of the tank part 8, 22 is a shutter, 23 is a bag holder, and 24 is a hook for locking the tank part 8 and the top cover 25. .

In the above-mentioned device, the grain is carried out from the threshing section 1 and transferred to the hoisting cylinder 4.
The grains lifted by the rotary thrower 11 are first thrown toward one side of the grain removal section 7 as shown in FIG. When the grain is deposited on the front surface 1 of the grain and the sensor detects it, the control circuit is turned on, and the rotating thrower 11 rotates by a predetermined angle and stops. When the grains are filled, the rotating thrower 11 sequentially rotates intermittently at a constant angle.

In this way, when the inside of the grain removal section 7 and the tank section 8 are full, if the machine is operated by one person, the machine is stopped, the shutter 22 is closed, and the full paddy bags 12, 12, etc. are emptied. When the shutter 22 is opened and the tank section 8 is pushed up by the hydraulic cylinder 15, the grains in the tank section 8 flow into the paddy bags 12, 12...
The grains falling from the rotating thrower 11 which rises together with the tank portion 8 are received by the auxiliary hopper 20 and flow into the spare paddy bag 12'.

At this time, the grains that are to be scattered outside the machine through the opening 8a and the rotating thrower 11 are not received and guided by the expansion/contraction member 17, and are all collected into the grain removal section 7 and the auxiliary hopper 20.

Once the grains in the tank section 8 have been taken out, the hydraulic oil in the hydraulic cylinder 15 is pushed out by the weight of the tank section 8, and the tank section 8 is lowered. It is folded up and stored in the downward storage portion of the U-shaped storage body 16, and the rotating thrower 11 is connected to the upper end of the grain lifting cylinder 4.

Since the present invention is configured as described above, when the tank portion 8 is tilted upward to take out the grains filled therein, a large amount of grains flowing down will not come into contact with the expansion/contraction material 17, and the expansion/contraction material 17 will be removed. Abrasion can be prevented, and when the tank part 8 is lowered, grains will not be caught in the folds of the expansion material 17, and cracks can be prevented from forming in the expansion material 17. .

Furthermore, when the tank section 8 is lowered and set on the grain removal section 7, the expansion material 17 enters the storage section, so the expansion material 17 may collide with an obstacle and be damaged, or be exposed to rain, reducing its durability. never lose.
