Description

[Detailed Description of the Invention] The present invention relates to a support device for supporting the rear of a grain tank in a large combine harvester having a grain tank in which a plurality of poppers are arranged in series.

Conventionally, in large combine harvesters that cut four or more rows, workers had to climb on top of the threshing equipment when maintaining, cleaning, or inspecting the rear upper part of the machine, such as the grain tank, which was not only extremely dangerous, but also It was troublesome as it required a platform to climb.

On the other hand, the grain tank requires a space for hanging rice bags, so it is installed at a high position, and the front part is directly supported by the driver's side frame, but the rear part is supported by a pipe. It was supported by the fuselage frame.

Therefore, in the present invention, the rear of the grain tank is supported by two supporting metal fittings erected on the fuselage frame, and
By constructing a large number of horizontal bars at intervals between the book support fittings so that the legs can be raised and lowered in a grain-like manner by alternating, the support metal fittings are reinforced and can also be used as ladders. The object of the present invention is to provide a grain tank support device for a combine harvester which eliminates the above-mentioned drawbacks.

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

As shown in FIGS. 1 and 2, the combine 1 has a body frame 3 supported by crawlers 2,
An engine 5 and a threshing device 6 are mounted on the frame 3, and a driver's seat 1 is provided at the upper part of the front side.

Furthermore, a pre-processing section 8 is supported at the front of the machine frame 3 so as to be able to rise and fall freely, and the pre-processing section 8 includes a cutting blade 10, a pulling device 11, a conveying device 12 for conveying the culm to the threshing device 6, etc. have.

On the other hand, a grain tank 13 is arranged on the side of the threshing device 6 and behind the driver's seat T, and the grain tank 13 has three impers 13a, 13b, and 13c.

There is a space below the discharge port of Homper 131...
Three rice bags 15, .

Further, at the rear upper part of the grain tank 13, a discharge port of a grain lifting cylinder 1T for transporting the grains from the threshing device 6 is provided, and furthermore, at the upper part of the tank 13, the grains can be transported from the rear to the front. A screw 1B is provided.

Further, as shown in FIG. 1, the grain tank 13 has its front part supported by a driver's seat side frame 19 that supports the driver's seat 7, etc., via a bracket 19a, and its rear part supported by a driver's seat side frame 19 that supports the driver's seat 7, etc. As shown in detail in FIGS. 2 and 3, it is supported by two support vibes 20 and 20 erected on the body frame 3.

Between the two support pipes 20 and 20 are a large number of horizontal bars 21 and 20, which can be raised and lowered in a row-like manner by alternating their legs.
... has been constructed, and the horizontal beam 21 is the support pipe 2.
00 prevents buckling and can also be used as a ladder.

Further, as shown in FIG. 3, the upper end of the support pipe 20 is bent and a support plate 22 is welded to it, and a horizontal bar 21' at the upper end is formed in a box shape, and a grain tank is attached to the end of the horizontal bar 21'. 13
The support plate 23 is aligned with the inclined surface 13b of the bomber 13a.
is fixed to the grain tank 13t''! and the support pipe 20 so that the upper surface 13c and the inclined surface 13b of the grain tank 13 are held between the supporting plates 22 and 23.

In addition, 13d in FIG. 1 is a lid provided on the upper part of the grain tank 13 so that it can be opened and closed.

Since the present invention has the above-described configuration, during the combine harvester operation, the husk cut in the pre-processing section 8 is conveyed to the threshing device 6, where it is threshed and sorted, and the sorted grains are The grains are transported to the grain tank 13 by the grain carrier 11.

The grain hash screw 18 in the grain tank 13 sequentially fills the pumpers 13a, 13b, 13, but by opening the discharge ports of the pumpers 13a..., the grains in the pumper are suspended by the loading fittings 16. Pack the paddy into bags 15.

At this time, in order to check the storage condition of grains in the grain tank 13, the driver or other worker should alternately place his or her feet on the horizontal bars 21 of the support pipe 20 at the rear of the machine. ,
Using the horizontal bar 21 as a ladder, put your face and hands above the grain tank 13, and open the lid 13d to see inside the grain tank 13.

In addition, when inspecting, maintaining, or cleaning the upper part of the machine other than inspecting the grain tank 13, the horizontal bar 21 of the support pipe 220
Of course, you can use it as a ladder.

As explained above, according to the present invention, the grain tank 13
There is no need to climb on top of the threshing device 6, etc. when looking into the inside of the machine, or when maintaining, cleaning or inspecting the upper part of the machine.
Since the operator can climb up, there is no need for a stand or the like, and even a large combine harvester with a height of 2 meters or more can be easily climbed, and the upper part of the machine can be easily maintained, cleaned, and inspected.

In addition, the horizontal bar 21 can not only be used as a ladder, but also acts as a reinforcing frame for the support pipe 20, so even in a heavy state full of grains, the grain tank 13 can be protected from vibrations of the aircraft. Be able to endure and support safely.

In the above-described embodiment, a pipe is used for the support fitting 20 in order to reduce the weight, but it is of course possible to use other materials such as a solid round bar.
