Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain storage device in a mobile threshing machine.

Conventionally, there are two types of grain storage: the grain tank specification, which is carried out by a single operator, and the grain bagging specification, in which there is a dedicated bag replacement worker in addition to the operator, but each specification is different. It was dedicated to this machine, and it was not possible to switch and use it as needed.

An object of the present invention is to realize a grain storage device in which grain tank specifications can be switched to grain bagging specifications by particularly devising a grain tank.

For this reason, the following technical measures were taken.

That is, in the grain tank 2 configured to receive and store grains from the grain lifting cylinder 9 on the side of the threshing device 1, and to discharge the stored grains through the grain removal spiral 25 at the lower part, the grain tank On the outer wall surface 2a of the grain tank 2, a grain take-out part 4 is opened and provided so that bags can be taken out, and a shutter 13 is provided in the opening of this take-out part 4.
A guide body 5 is provided in the inside for receiving the grains from the grain lifting cylinder 9 and guiding the received grains down to the grain take-out part 4. It is configured to be able to switch freely between a working posture state (A) in which the grains are guided and a non-guidance working posture state (B) in which the grains are dropped into the grain take-out spiral 25 below, and the grain take-out section 4 is provided with a shutter 15 that can be opened and closed. The structure of the grain storage device in a mobile threshing machine is characterized in that a discharge tube 16 is provided in a removably connected manner.

In the illustrated example, A is a combine harvester, which includes a threshing device 1 mounted on a chassis having a traveling device 6, a reaping conveyance section 7 provided in front of the threshing device 1, a grain tank 2 arranged side by side on one side of the threshing device 1, and a driver's seat section 8, which is conventionally known.

Reference numeral 9 denotes a grain lifting cylinder that lifts and transfers the grains from the threshing device 1 to the upper part of the grain tank.

In the grain tank 2, a grain transfer spiral 3 is rotatably suspended horizontally in the upper part, and grain take-out parts 4, 4 are opened on the left and right sides at a predetermined interval on the outer wall surface 2a. Reference numeral 10 denotes a receiving trough extending halfway from the transfer start end of the grain transfer spiral 3, and is constructed by supporting a shaft 12 on a helical case 11 so as to be rotatable to open and close.

Reference numeral 13 denotes a shutter for opening and closing the opening of each of the grain extraction parts 4, 4. The shutters 13a, 13b are divided into upper and lower parts, and each shutter 13a, 13b is pivoted around a shaft 14 so as to be rotatable to open and close, and is always closed by a spring. It is configured with a bullet bias.

Reference numeral 16 denotes a discharge tube with a shutter 15, which is configured to be detachably attached to the openings of the grain removal sections 4, 4. 17 is a set bolt, and 18 is a pair of left and right bag support rods provided to support the grain bag 19 with the bag opening facing the discharge tube 16.
It is configured so that it can be attached and detached freely. Reference numeral 20 denotes a backrest that receives and supports the back of the bagging worker, and is configured to be rotatable and switchable between a working position and a non-working position in which it rotates above the grain tank 2.

21 is a carrier configured to be freely rotatable up and down.

The guide body 5 is arranged side by side on the left and right corresponding to the grain extraction parts 4, 4, and its tip end side 5b is pivotably supported to be vertically movable around a shaft 22 that fixes the base part 5a to the tank 2. The left and right edges 5c, 5d stand upward and are tapered toward the center from the base side 5a to the tip side 5b. When the guide body 5 rotates upward, its tip end side 5b communicates with the opening of the grain removal section 4 and is configured to be in an operating position A that tilts downward, and when it rotates downward, the grain tank 2. It is configured to be in a vertical non-working position along the wall surface (B).

Note that the receiving gutter 10 is connected to the base 5 of one guide body 5.
It extends to within the left and right width of a.

In addition, the receiving gutter 10 has a discharge pipe 1 corresponding to that side.
The receiving gutter 10 rotates to open when the shutter is "open" and rotates to close when the shutter is "closed" through the shutter 15 and wire 23 of No. 6. The backrest 20 and the left and right guide bodies 5 are arranged such that when the backrest 20 is rotated to the working position C, the guide body 5 is rotated upward to the working position A, and when the backrest 20 is rotated to the non-working position D. 2 is an interlocking mechanism 2 constituted by a link such as an arm so that the guide body 5 rotates downward and switches to the non-operating posture state B.
It is configured to be linked via 4.

25 is a grain extraction spiral provided at the bottom of the grain tank.

In addition, the above-mentioned interlocking mechanism 24 and wire 23
is provided outside the grain tank 2, and the wire 23 is configured to be detachable from the receiving gutter 10.

In the configuration of the above example, when performing combine harvester work with the grain tank 2 specification, when the backrest 20 is rotated to the non-working position 2, the guide body 5 is interlocked and rotated downward via the interlocking mechanism 24 to be in the non-working position. Posture state becomes RO. Therefore, the grains from the threshing device 1 are sent to the starting end of the grain transfer spiral 3 via the grain lifting cylinder 9, and are sequentially stored and deposited in the grain tank 2 from the terminal end of the receiving trough 10. . In this case, the guide body 5 is
Since it is evacuated from the falling path of grains, it does not inhibit the falling and sedimentation of grains. Next is Glentank 2
When the grains are filled in the tank 2, the operation is temporarily stopped and the grains are discharged to the outside of the tank 2 through the grain removal spiral 25.

In addition, if you have a dedicated bag replacement worker and you are working on a combine harvester with grain bagging specifications, first
6 to the grain removal part 4 and the upper and lower shutters 13a, 13
After inserting b while pushing and expanding it against the spring,
Fix with set bolt 17.

Next, when the backrest 20 is rotated to the working position C, the guide body 5 is interlocked and rotated upward as much as possible to the working position A via the interlocking mechanism 24. grain bag 19
is supported by the bag support rod 18 and the shutter 15 on the side corresponding to the receiving gutter 10 is opened, the receiving gutter 10 is opened via the wire 23 and the lower part of the spiral 3 is released. When an operator rides on the carrier 21 and performs combine harvesting work, the grains fed to the grain transfer spiral 3 are directly received by the guide body 5 and do not fall to the bottom of the grain tank 2. The grain bag 1 is guided down to the take-out part 4 and is passed through the discharge pipe 16.
It is stored in 9. After filling the grain bag 19, if the shutter 15 is closed, the wire 23
Since the receiving trough 10 is "closed" through the spiral 3 and blocks the lower part of the spiral 3, the grains are transferred and supplied by the spiral 3 to the next guide 5 and then passed through the guide 5 to this side. The grains are guided down to a certain grain removal section 4 and packed into a grain bag 19 via a discharge tube 16. The bag changing operator repeatedly performs the above-mentioned work, but since he is supported by the backrest 20, he can do it easily.

Since this invention has taken the above-mentioned technical means, by switching the guide body 5 to the operating posture state A, it is possible to make the grain tank 2 specification with a large grain storage capacity. A large amount of grain will be stored in the To discharge the grains, they can be discharged out of the tank by means of the lower grain removal spiral 25.

When the guide body 5 is switched to the non-operating position B, while using a part of the inside of the tank as a tank,
The grains in the tank are guided down to the extraction part 4 side, and the discharge tube 1 is opened by opening the shutter 15.
6 into the bag 19.

As described above, it is possible to switch from the grain tank 2 specification, which has a large grain storage capacity, to the bagging specification, depending on the necessity, which is very convenient. Moreover, since this switching is performed by the operation of the guide body 5 provided in the grain tank 2, the structure is simple and the switching operation can be performed quickly.

In addition, if such a bagging specification is not required, the discharge tube 16 with the shutter 15 can be easily attached and detached, so it can be removed from the grain tank and used as is for exclusive use with the grain tank specification. It is possible.
