Abstract

PURPOSE:To improve the diffusion and distribution of grains in a grain tank of a combine harvester and reinforce the grain tank by providing an integral structure of a bucket elevator in an inside corner part of the grain tank. CONSTITUTION:The objective grain tank has a construction equipped with a bucket elevator 3 for lifting grains integrally installed in a wall plate in an inside corner part 2 of a grain tank 1 in a square shape when viewed in a plane. Diffusion blades 5 for diffusing grains discharged from a discharge port 4 at the upper end of the bucket elevator 3 are provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain tank for accommodating threshing grains of combine, and is intended to uniformly disperse the grain-raising grains supplied by a bucket elevator into the grain tank.

[0002]

2. Description of the Related Art When storing grains to be sublimated in a bucket elevator in a grain tank, it is difficult to store them in a uniform manner. It is likely to occur, and is easily restricted when the capacity of the Glen tank is small or the lift of the bucket elevator is high.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a bucket elevator 3 for grain raising is integrally provided on a wall plate of an inner corner 2 of a Glen tank 1 having a rectangular shape in a plan view, This bucket elevator 3 outlet 4 at the upper end
The grain tank of the combine is provided with the diffusion blades 5 for diffusing the grains discharged from the grain.

[0004]

[Operation and effect of the invention] Grains threshed by the threshing unit are lifted by the bucket elevator 3, guided from the discharge port 4 to the diffusion blades 5 and dropped and accumulated while being diffused in the grain tank 1. It At this time, since the bucket elevator 3 is located at the inner corner of the grain tank 1, the blind vane of grain diffusion by the diffusion blades 5 that perform the diffusion action under the outlet 4 of the bucket elevator 3 is narrow. In addition, the capacity of the grain tank 1 can be increased, and the capacity can be diffused as uniformly as possible to increase the accommodation amount. This can be done by the diffusion blades 5 near the outlet 4 of the bucket elevator. And the height of the discharge port 4 and the like can be made as low as possible, and the case portion of the bucket elevator 3 constitutes or reinforces the corner portion of the grain tank 1 to enhance vibration resistance.
The weight can be reduced and the rigidity can be increased.

EXAMPLE A combine is a harvester 1 having a cabin 8 having a pair of left and right crawlers 6, a cabin 8 for covering a cockpit section, a cutting blade device, a reel 9 and the like in addition to the Glen tank 1.
0, a threshing device 11 for threshing a grain culm conveyed by the reaping device 10, an engine E for driving these parts, and the like are mounted.

The grain tank 1 has a rectangular box shape in plan view on the side of the threshing device 11, and an elevator case 12 having a rectangular cross section is integrally formed in a corner 2 at the rear end near the threshing device 11. Set up in. In this elevator case 12, a bucket conveyor 13 is stretched inside, but a part of the wall surface of the corner portion 2 of the Glen tank 1 facing a wall board of a part of the Glen tank 1 is rectangular as shown in FIG. It may be configured to be entirely located inside, or may be exposed or projected to the outside as shown in FIG. Further, the wall plate itself of the Glen tank 1 may constitute a part of the elevator case 12.

The lower end of the bucket elevator 3 is connected to the lateral end of the first gutter 14 for extracting threshing-selected grains of the threshing device 11, and the harvested grains taken out from the first gutter 14 are transferred to the bucket conveyor 13. And is made to flow down into the Glen tank 1 from the upper end discharge port 4 of the elevator case 12. The diffusion blade 5 is located directly below the discharge port 4 and stores the flowing-down grain while diffusing it to the surroundings by rotation. The diffusion blade 5 is rotated around the blade shaft 15 in the vertical direction, and is rotationally driven by an independent transmission mechanism, a dedicated motor, or the like.

When the Glen tank 1 has a rectangular shape in a plan view, the rotating shaft 16 of the bucket conveyor 13 is arranged along the short side direction, and the diffusion blades 5, the discharge port 4, etc. are arranged in the longitudinal center of the Glen tank. By locating on the side
Even if the diffusion zone is widened and the diffusion blades 5 are provided near the discharge port 4, the range A which is the blind spot due to the elevator case 12 of the bucket elevator 3 is narrowed. In particular, as shown in FIG. 2, when the side of the bucket elevator 12 opposite to the discharge port 4 is projected outward from the wall plate of the corner 2 of the Glen tank 1, the dead angle range can be further narrowed. .

In the illustrated example, the elevator case 1
The inner case 17 of the portion in the Glen tank 1 of No. 2
Is a structure that can be opened and closed by rotating it around a vertical hinge 18 of the rear side wall part, and this opening and closing end part can be opened and closed so that it can be fastened and fixed to the inner surface of the side wall plate of the Glen tank 1 with a bolt 19. Reference numeral 20 denotes a transmission belt, which is stretched over between the adjusting shaft 16 at the upper end of the bucket elevator 3 and the transmission shaft 21 of the diffusion blade 5 mounted at the discharge port 4 of the bucket elevator 3, Spiral shaft in gutter 14, bucket conveyor 13, wheel control shaft 16, transmission belt 2
0, the transmission shaft 21, and the rotating shaft 15 are transmitted in this order to rotate the diffusion blade 5.

A spiral shaft 22 is provided at the bottom of the grain tank 1 in the front-rear direction so that the grains to be stored can be discharged and transferred. A discharge auger 2 is provided at the rear end of the spiral shaft 22.
3, 24 are arranged in series, and the discharge auger 23 turns, and
By vertically moving the discharge auger 24 or the like, the discharge direction is selected and the grain is discharged to a predetermined position. Reference numerals 25 and 26 are the control cylinders.
