DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing apparatus for a threshing apparatus, and more particularly, to a second apparatus for returning a second product collected in a second product recovery section of a threshing apparatus to a starting end of a swing sorting apparatus. The present invention relates to a material reduction device, a grain-lifting device that discharges grains collected in a first-item collection unit to a Glen tank, or a grain-lifting device that discharges grains in a Glen tank outside the machine.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Application Laid-Open No. 63-78553, a grain tank frying apparatus is composed of a horizontal screw conveyor and a vertical screw conveyor, and a horizontal screw conveyor and a vertical screw conveyor. The conveyor is interlocked and connected via bevel gears. And
These conveyor cases are constituted by an elbow-type casting case connected to the side wall of the Glen tank, and a pipe case such as a steel pipe fitted and connected to the upper part of the elbow-type casting case.

[0003]

The casting case is heavy in weight, which is one of the factors that increase the weight of the combine body which is desired to be reduced in weight. The elbow type case is formed integrally with a bevel gear bearing that interlocks the end of the horizontal screw conveyor and the start of the vertical screw conveyor, and the pipe case of the vertical screw conveyor is Since the conveyor is fitted and connected to the elbow type casting case, if jamming occurs in the conveyor, the case cannot be disassembled and the jamming removal operation cannot be performed.The jamming removal operation must be performed by reversing the screw conveyor, etc. Therefore, it is difficult to perform the clogging removal operation.

[0004] It is an object of the present invention to reduce the weight and facilitate maintenance of a fryer by devising the structure of a conveyor case.

[0005]

[Action]

The conveyor case is divided into a bearing part and a case part, and the bearing part having the supporting strength of the screw conveyor is made of casting as in the past, and the outer cylinder is made of sheet metal that does not require strength, so that Weight can be reduced. In addition, when clogging occurs by dividing the case into 20% on the left and right sides, maintenance can be performed by removing the case on one side. [Effect] The above configuration results Hakare the weight of the AgeKoku device, weight reduction can be achieved is aircraft weight lighter of Nozomu <br/> or Shiiko Nbain. Also,
Since the conveyor case is 20% left and right, leaving the bearing,
When clogging occurs, the case can be disassembled in a state where the screw is securely supported, and the clogging removal operation can be easily performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to a threshing apparatus mounted on a combine. As shown in FIG. 1, this threshing apparatus 1 performs a threshing process on a grain stalk conveyed by a feed chain 4 by a handling cylinder 2 and a receiving net 3, and removes the processed material leaked from the receiving net 3 into grains. In the swing sorting case 5 that performs specific gravity sorting on the grain and the straw, the upper grain pan 6 and the chaff sheave 7 roughly sort the grain and the straw dust, and the lower grain pan 8 and the grain sieve 9
And the first of the grains leaked from the Glen Sheave 9 is collected in the first thing collection part 12 and discharged out of the machine, and the stabbed rice and the branches discharged from the end of the Glen Sheave 9 are attached. The second product such as paddy is collected in the second product collection unit 13 and returned to the starting end of the swing sorting case 5 through the second product reduction device A as a frying device to be reprocessed. I have.
In the processed material discharged from the dust outlet 3 a at the rear end of the receiving net 3, the straw waste is discharged out of the machine via the first straw rack 10 and the second straw rack 11, and is placed on the swing sorting case 5. Dust such as rice husks and small straw debris floating in
The air is discharged to the outside of the apparatus by a sorting wind generated by the air blower and a suction wind generated by the dust blower 16.

[0007] As shown in FIG.
Is composed of a horizontal screw conveyor 17 disposed in the second product recovery section 13 and a vertical screw conveyor 18 disposed at the end of the horizontal screw conveyor 17. The vertical screw conveyor 18 is provided with a grain scraping feather 17a, and at the upper end of the vertical screw conveyor 18, a grain discharge blade 18a is provided. The horizontal screw conveyor 17 and the vertical screw conveyor 18 are interlocked and connected via bevel gears 19, 20. The bevel gears 19, 20 are mounted on bearings 22, 23 in a bevel case 21 as a bearing formed by casting. It is rotatably supported via.
The conveyor case 24 for the horizontal screw conveyor 17 and the vertical screw conveyor 18 is provided with an orthogonal portion a between the horizontal screw conveyor 17 and the vertical screw conveyor 18.
The entire case including the right and left is formed of a left and right split metal sheet case, has a discharge port 24a at the top, and has a right and left split flange 2 at a contact portion for the threshing device.
4b are fixedly connected to each other, and the left and right split sheet metal cases
5 are connected and integrated. The upper portion of the vertical screw conveyor 18 is rotatably supported via a bearing on a lid 26 which is detachable from the conveyor case 24 via bolts via bolts. Further, the outer side of the orthogonal part a of the conveyor case 24 is obliquely cut away and has an opening 24d.
The bevel case 21 is fixedly connected to the conveyor case 24 via a bolt through the opening 24d.

[Another embodiment] The present invention relates to a grain-lifting apparatus for discharging grains collected in a first-item collecting section to a Glen tank.
Alternatively, it can be applied to a grain tank frying apparatus.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
