Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a grain collecting device for a combine harvester.
Specifically, the present invention relates to a grain collecting device for a combine harvester in which a grain tank for storing grains from a threshing device lifted and transported by a grain lifting device is configured to be horizontally swingable toward the outside of the machine body.

[Conventional technology]

In the grain collecting device of the combine, the bottoms of the first grain collecting section and the second grain collecting section, and the
It is necessary to periodically clean the grains and dust remaining at the bottom of the connection case that connects the grain collecting section and the grain lifting device that transports the grains from there to the grain tank. Therefore, conventionally, the first item collection section and the second
A lid body that can be opened and closed is provided at each bottom of the grain collection section and the bottom of the connection case, and the lid body is opened using an operating lever provided on the side of the machine to perform the cleaning operation of the grains and dust. I was planning to do it.

By the way, the operation lever of the lid body provided at the bottom of the connection case is directly connected to the side of the grain frying device where the connection case is located, The operating lever of the lid body provided at the bottom was placed on the opposite side of the grain lifting device where the grain tank was placed so as not to interfere with the turning operation of the grain tank.

[Problem that the invention attempts to solve]

However, when using such a conventional grain collecting device, when cleaning the grains and dust remaining at the bottom, first the first part and the second part are cleaned.
In order to open the lids at the bottom of each grain collection section, operate the operating lever on the grain refluxing device side of the machine, clean the grains and dust remaining at the bottom, and then connect the In order to open the lid at the bottom of the case, after operating the control lever on the vertical feeding device side of the machine, it was necessary to clean the grains and dust remaining at the bottom. Therefore, the worker had to work while circling around the machine, which resulted in poor work efficiency.

The present invention aims to solve such problems.

[Means for solving problems]

The grain collecting device for a combine harvester according to the present invention is a grain collecting device having the above-mentioned configuration, and includes a first cleaning port formed at the bottom of the first material collecting portion in the threshing device and a second cleaning port formed at the bottom of the second material collecting portion. A first lid body and a second lid body are respectively provided in a second cleaning opening formed at the bottom so as to be able to swing open and close.
The present invention is characterized in that an operating lever for swinging the lid to open and close is provided in a space between the grain lifting device and the threshing device.

[Effect]

In this proposed device, the operating levers for opening and closing the lids at the bottoms of the first and second product collection sections are provided in the space between the grain hoisting device and the threshing device. , the position of the operating lever and the operating lever for opening and closing the lid at the bottom of the connection case are concentrated on the same side of the machine body.

Therefore, if the grain tank installed outside the grain lifting device is horizontally rotated to enable horizontal rotation and the grain tank is moved to the outside of the aircraft,
The operator can now operate both of the levers described above on the same side of the machine with almost no movement.

[Effect of idea]

Therefore, according to the present device, it is no longer necessary for the operator to go around the machine body in order to clean the grain collection section and the bottom of the connection case, which is the case in the past, and the work efficiency is improved. will be significantly improved.

Note that the operating levers for opening and closing the lids at the bottom of the first and second product collection sections are provided in the space between the grain lifting device and the threshing device, while the grain tank is Since the operating lever is provided outside the grain device, it does not interfere with the turning operation of the grain tank.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

The threshing device 1 is constructed as shown in FIG.

That is, the threshing section 6 is configured such that the harvested grain culm is supplied to the handling chamber 4 by the threshing feed chain 3 and threshed by the rotating handling drum 5, and the threshed grain is supplied falling from the handling chamber 4. A sorting device 7 that sorts the particles while shaking them, a winnower 8 that supplies sorting air, and a rotating fan 9 that sucks in dust and discharges it outside the machine.
A sorting section 10 having a sorting section 10 is provided extending from below to the rear of the threshing section 6. Then, there is a No. 1 object recovery section 11 that carries out the No. 1 processed object from the sorting section 10 to the lateral outside of the machine body, and a No. 2 recovery section 12 that carries out the No. 2 processed object from the sorting section 10 to the lateral outside of the machine body. is provided at the bottom of the sorting section 10, and the first collecting section 11
A screw conveyor type grain lifting device 14 that lifts and supplies the processed material from the grain tank 2 to the grain tank 2, and a thrower type lifting device that lifts and supplies the processed material from the second material collection section 12 to the handling room 4. A device 15 is provided on the outer side of the fuselage.

As shown in FIGS. 1 and 2, a first cleaning port 19 and a second cleaning port 18 are formed at the bottoms of the first and second collection portions 11 and 12, respectively, and
The first lid body 2 opens and closes the cleaning ports 19 and 18.
0 and the second lid body 21 on the horizontal axis along the width direction of the aircraft.
It is provided around P ₁ and P ₂ so that it can swing open and close. Connecting plates 22 and 23 are provided upright on the first lid body 20 and the second lid body 21, respectively, and a first helical spring 26 and a second helical spring 27 are attached to these connecting plates 22 and 23, respectively. and their free ends are pivotally supported at both ends of the rotation link 28.

The rotation link 28 is connected to an operating lever 29.
The operating lever 29 is vertically provided in a space A formed between the threshing device 1 and the grain lifting device 14.

Further, the grain tank 2 is provided outside the grain lifting device 14 so that it can horizontally turn outwards from the machine body around the vertical axis Q along the height direction of the machine body (see the imaginary line in FIG. 5). There is.

Furthermore, the first product collection section 11 and the grain frying device 1
4 is provided with a connecting case 30 that connects the two, and a cleaning opening 31 is formed at the bottom of the connecting case 30 as shown in FIGS. It is provided so as to be able to swing open and close around the horizontal axis R along the width direction. Then, the lid body 3
2 has a rotating link 34 via a helical spring 33.
are connected to each other, and the rotation link 34 can be rotated by an operating lever 35 directly connected thereto.

In the case of such a device, the first object collection section 11
and lids 20 and 21 at the bottom of the second item collecting section 12.
The operating lever 29 for opening and closing the grain frying device 14
Since it is provided in the space A between the operating lever 29 and the threshing device 1, the position of the operating lever 29 and the connecting case 3
The operating lever 35 for opening and closing the lid body 32 at the bottom of the aircraft is concentrated on the same side of the aircraft body.

Therefore, when the grain tank 2, which is provided outside the grain lifting device 14 so as to be able to horizontally turn, is horizontally turned to move the grain tank 2 to the outside of the machine, the operator can move both of the above-mentioned levers. Operations 29 and 35 can be performed on the same side of the aircraft with almost no movement.

Note that the operating lever 35 may be provided on the space A side. In this way, the operating lever 3
5 is provided at a position closer to the operating lever 29, and its working efficiency is further improved.
