Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a combine grain tank.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Laid-Open No. 63-79524, a grain tank is arranged on the side and above the thresher in a carp, and the side tank is arranged on the rear longitudinal axis. It is known that the upper tank is horizontally rotatable, and the upper tank is vertically rotatable about a horizontal axis in the front-rear direction opposite to the side tank.

[0003]

In the above-mentioned conventional apparatus, the tank capacity can be increased by disposing the grain tanks on the side and above the threshing device, and the side tanks can be arranged in the rear vertical axis center. While rotating outward, the upper tank is rotated upward around the horizontal axis on the side opposite to the side tank for maintenance and inspection of the threshing device. When carrying out inspections and cleaning, it is necessary to work in a narrow space created by rotating the side tanks outwards and to work in a place with poor scaffolding. The inspection of the feed chain part and the removal work when the grain culm is clogged have the disadvantage that a large upper tank remains above it, making it extremely difficult. Further, in the above-mentioned conventional one, even if the side tank and the upper tank are integrally rotated outward with respect to the center of the rear longitudinal axis, the upper tank cannot contact the front driving operation part and cannot rotate. If the grain tank and the operation portion are largely separated in the front-rear direction so that they do not come into contact with each other, the entire machine body becomes large. An object of the present invention is to improve the above conventional problems.

[0004]

According to the present invention, a mowing device is provided at the front part of the machine body, and a driving operation part is provided at one side of the rear part thereof.
A threshing device and a grain tank are installed side by side behind the operation operation unit,
In the combine, wherein the grain tank is composed of a side tank located immediately to the side of the thresher immediately after the operation and operation unit and an upper tank located integrally with the side tank and above the thresher, The tank is configured so as to be horizontally rotatable toward the outer side with respect to the rear vertical axis center, and the upper tank is extended above the threshing device and the side tank is retracted to the side tank side to see the side tank in plan view. It is characterized in that it can be switched to a non-working position where it overlaps.

[0005]

When the transmission device 8 located between the threshing device 5 and the side tank 10a is inspected, or when the threshing device 5 is maintained or cleaned, the operator places the upper tank 10b in the side tank 10a.
The side tank 10a is moved to the side and retracted to switch to a non-working position where the side tank 10a overlaps with the side tank 10a in a plan view (c state of FIG. 3), and the side tank 10a is pulled outward with the grip 22.
Is horizontally rotated outward together with the upper tank 10b about the lifting cylinder 15a, that is, the vertical axis. At this time, the upper tank 10b is retracted to the side tank 10a side and is seen in a plan view.
Since it is in the non-working position c where it overlaps with a, the grain tank 10
Even if the upper tank 10b is horizontally rotated, the upper tank 10b does not come into contact with the driving operation unit 4 in front. Then, as described above, the side tank 10a and the upper tank 10b are integrally rotated outward to open the sides and the upper side of the threshing device 5 all at once, and then the worker threshes with the side tank 10a and threshing. The inspection and maintenance of the transmission device 8 between the devices 5 and the cleaning lid 7 are opened to clean the inside of the threshing device 5, and the cylinder cover 6 on the upper part of the threshing device 5 is pivotally opened upward around the fulcrum 5a. Then, the inside of the handling chamber above the threshing device 5 is inspected and cleaned from the outer side position of the threshing feed chain, that is, the place outside the machine body which is large and has a good foothold. Further, maintenance of the threshing feed chain and removal of jammed culms can be performed from the outside position on the threshing feed chain side.

In the above embodiment, the combine harvesting work is carried out with the upper tank 10b in the working position A overhanging above the threshing device 5, and the threshed and sorted grains are fed from the tip of the grain frying barrel 9 to the grain. It is discharged into the grain tank 10. When the grain tank 10 is full, the worker interrupts the harvesting work and operates the operation lever (not shown) to move the grain discharge cylinder 15
Is operated to discharge the grain to the loading platform of a truck on the road. At this time, in the embodiment shown in FIGS. 1 to 4, the operator extends the hydraulic cylinder 12 with the operation lever (not shown) and tilts the upper tank 10b upward to move to the grain discharging position a, whereby the upper tank is discharged. The grain in 10b flows down to the side tank 10a and is discharged by the grain discharge cylinder 15.
In the embodiment shown in FIGS. 5 and 6, when the grains in the side tank 10a are discharged, the grains in the upper tank 10b naturally flow down to the side tank 10a due to the inclination of the bottom plate.

Next, the inspection and cleaning work of the threshing device 5 and the like will be described. When inspecting the power transmission device 8 located between the threshing device 5 and the grain tank 10 and maintaining or cleaning the threshing device 5, the operator first operates the movable barrel 15b of the grain discharge barrel 15 with a lever ( The movable cylinder 15b is rotated upward by a not-shown).
After evacuating the above from the threshing device 5, the upper tank 10
b is moved and retracted to the side tank 10a side, and is switched to a non-working position c where it overlaps with the side tank 10a in plan view. Next, hold the handle 22 and pull the side tank 10a outward,
The lifting tank 1 integrally includes the side tank 10a and the upper tank 10b.
Horizontally rotate outwardly around 5a. At this time, since the upper tank 10b is retracted to the side tank 10a side and is in the non-working position c state where it overlaps with the side tank 10a in a plan view, even if the grain tank 10 is horizontally rotated, the upper tank 10b is moved forward. Therefore, the grain tank and the operation control section can be arranged as close to each other as possible without contacting the operation control section 4. Then, as described above, both tanks 10a and 10b are integrally rotated outward to open the sides and the upper side of the threshing device 5 all at once, and then the operator is placed between the side tank 10a and the threshing device 5. Inspecting and servicing the transmission device 8 and cleaning the inside of the threshing device 5 by opening the cleaning lid 7, and inspecting and cleaning the handling chamber from above the threshing device 5 and arranging the threshing feed chain. When removing the clogging of grain and culm, the cylinder cover 6 on the upper part of the threshing device 5 is further supported by the fulcrum 5
Rotate upward about a and open from the outside position of the machine on the threshing feed chain side. Therefore, the inspection and maintenance work of the handling room and the threshing feed chain portion can be easily performed from a spacious and well-scaffolded place outside the fuselage without being hindered by the upper tank 10b. The culm can be reliably removed.

[0012]

As described above, according to the present invention, the side tank is configured to be horizontally rotatable toward the rear center of the vertical axis toward the outside, and the upper tank is provided with the working position overhanging the threshing device. Since it is configured so that it can be retracted to the side tank side and switched to a non-working position where it overlaps with the side tank in a plan view, the grain capacity can be increased by arranging the grain tanks on the side and above the thresher. Although it can be increased, even if the upper tank is horizontally rotated integrally with the side tank, the upper tank does not come into contact with the driving operation section in front, and therefore the grain tank and the driving operation section are as much as possible. It is possible to make a compact body. Moreover, the two tanks can be integrally pivoted and retreated to the outside of the fuselage so that the sides and the upper side of the threshing device can be opened at once, so that the operator can operate the transmission device between the threshing device and the side tank. Not only can inspection and maintenance of the inside of the threshing device be performed from the cleaning port on the side of the threshing device, but also when performing inspection and cleaning inside the handling chamber from above the threshing device, You can work easily and safely from a spacious and well-scaffolded place outside the machine without being obstructed by the upper tank. Further, maintenance of the threshing feed chain, removal of jammed grain culms, and the like can be reliably performed from the outside position of the threshing feed chain without hindering the upper tank.
