Abstract

PURPOSE:To open a communicating part between a grain tank and helical type upper feeding column during rotation of the grain tank and to facilitate cleaning by installing the grain tank in a specific state rotatably around the center of a vertical shaft in the vicinity of the helical type upper feeding column. CONSTITUTION:A communicating part of a grain tank 3 and a helical type upper feeding column 5 is divided into communicating metals 4a and 4b and made joinable and separable. When the grain tank is changed in position to the outside of a combine, the communicating part is bent in the midst and opened between the communicating metals 4a and 4b.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a grain tank for a combine harvester in which a grain tank for storing grain from the threshing part is arranged in parallel in the lateral vicinity of the threshing part.

[Prior art and problems to be solved by the invention] Conventionally, in the structure where a grain tank is installed parallel to the threshing section,
Due to difficulty in maintenance such as inspection and maintenance of the threshing section,
The grain tank is rotated around the vertical axis toward the outside of the machine body on the side opposite to the threshing section to form a wide open work space on the side of the threshing section.

According to the grain tank having such a structure, the communication part with the helical lifting/unloading tube for lifting and transporting the grains from the tank is configured to be integrally communicated with the grain tank, so it is difficult to clean the communication part. Ta.

The present invention aims to solve the above problems by configuring the communication part to automatically open when the grain tank turns, without providing a special cleaning port. Measures were taken.

[Means to solve the problem]

That is, the characteristic configuration of the present invention is that a grain tank 3 is provided near the lateral side of the threshing section 1 to store grains from the threshing section.
are arranged side by side, and a helical lifting and carrying cylinder 5 for lifting and carrying out the grains from the tank is installed on one side of the front and back of this grain tank.
In the combine harvester in which the grain tank 3 is installed vertically, the grain tank 3 is constructed so as to be able to rotate around the vertical axis 9 provided near the helical lifting and unloading tube 5, and The grain tank 3 is mounted so that its position can be changed to the outside of the fuselage, and when the grain tank 3 is repositioned to the outside of the fuselage, the communication portion 4 between the grain tank 3 and the helical lifting and unloading cylinder 5 is bent from the middle. The point is that it is configured to open.

〔Example〕

An embodiment of the present invention will be described based on the drawings.

A reaping section 1 at the front of the machine, a threshing section 2 at the rear, and a grain tank 3 for storing grains from the threshing section 2. A helical lifting conveyor f, % 5, which lifts and carries out the grains sent through the communication part 4 by a cross-feeding conveyor provided at the bottom of the Glentongue 3, is hydraulically parked at the upper end of the lifting conveyor @5. A combine harvester is equipped with a discharge auger 6 connected via a device or the like so as to be able to swing up and down around a horizontal axis and to swing left and right around a vertical axis.

The grain tank 3 is arranged in parallel to the lateral side of the threshing section 2. The helical lift-out cylinder 5 is erected at the rear of the grain tank 3, and is firmly held on the body side by a support frame 7.

The communication part 4 is composed of a communication metal 4a on the side of the grain tank 3 and a communication metal 4b on the side of the helical lift-off tube S, and is constructed so that it can be divided from the middle and freely joined and separated. Of course, the transverse feed conveyor installed inside is also constructed so that it can be divided in the middle and can be joined and separated.

The Glenton 3 is supported by the holding frame 8 of the helical lifting and unloading cylinder 5 and the body side near the joint between the communicating metal 4a and the communicating metal 4b, and has a vertical shaft that serves as a pivot point for the tank. It is attached and held so that it can rotate freely around the core 9.

Reference numeral 10 denotes a working machine such as a cutter, which is mounted and supported at the rear of the threshing section so as to be able to swing open and close around a vertical axis 11 in the vertical direction. Vertical, which is the rotational fulcrum of this work machine! 11111 holds the bearing of the support frame 7↓. Further, the helical lifting and carrying out cylinder 5 is configured to be able to rotate around the helical axis in the vertical direction with respect to the holding frame 8.

A locking device is provided at the joint between the communicating metals 4a and 4b to integrally maintain this joint state, and the grain tank 3 is rotated around the helical axis 5a of the lifting/unloading cylinder 5 ( The structure is such that it can be switched between the single point chain (a) in FIG. 4 and the state in which the locking device is released and rotated around the upper shaft center 9 (double point chain g in FIG. 4). It is convenient to have it.

In FIGS. 5 and 6 of another embodiment, the helical lifting and unloading tube 5 is
It is rotatable around a helical axis mounted inside, and is interlocked with a pinion gear 13 and a swing gear 14 so as to be driven by a swing motor 12 . Accordingly, by the rotation of the lifting and unloading tube 5, the discharge auger 6 connected to the upper end is pivoted left and right.

The grain tank 3 is configured to be able to freely rotate around the lifting and carrying out cylinder 5p8 via a communicating cylinder 15 and a support metal 16 to the lifting and carrying out s5. 17 is integrally rotatable around the lifting and discharging tRJ5 together with the turning gear 14, and
The latch body is slidable in the axial direction, and when the pawl 17a is engaged with the locking hole 15a provided in the communication tube 15, the swing gear 14 and the communication tube 15 are locked together, The grain tank 3 rotates around the unloading pipe 5 with a rotating motor 12
It is configured so that it can be rotated immediately through the. Unloading cylinder 5
When the pawl 17b of the clutch body 17 is engaged with the locking hole 18a provided in the rotating metal 18 that is integral with the lifting and unloading cylinder 5 itself, it is driven to rotate around the helical axis via the rotating motor 12. It is configured so that (See Figures 5 to 7) Furthermore, the cutter 10 is configured to be able to freely pivot (swing open/close) around the lifting/unloading cylinder 5 via the cutter support metal 19, similar to the aforementioned grain tank 3. There is. Then, the claw 20a of the switching clutch 20 is attached to the cutter support metal 19.
When the cutter 10 is engaged with the locking hole 21 provided in the locking hole 21 provided in the pinion gear 13. It is configured to be driven to rotate via a rotation gear 14. (See Figures 8 and 9)
Note that 22 is a clutch switching lever.

Operation] When performing maintenance and inspection on the lateral side of the threshing section, by rotating the grain tank around the vertical axis toward the outside of the machine on the opposite side to the threshing section, the lateral side of the threshing section can be inspected. It becomes a wide open shape. Therefore, a worker can enter and exit the open space to perform maintenance.

In addition, when the grain tank is moved to the outside of the machine, the communication part between the grain tank and the helical lifting and unloading tube bends and opens from the middle, so the grains staying in the communication part are removed from the opening. can be removed from the area for easy cleaning.

〔Effect of the invention〕

Therefore, according to the present invention, a wide working space can be obtained between the threshing section and the grain tank, and maintenance can be easily performed.

Furthermore, when the grain tank turns, the communication part with the lifting and unloading cylinder is divided into two parts, making it easier to clean the transfer part.
