Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general-purpose combiner in which a screw type rotor is arranged at right angles to a traveling direction.

[0002]

2. Description of the Related Art Generally, a general-purpose combiner projects a cutting section forward from a traveling device, conveys grain stalks cut by the cutting section rearward and supplies it to a threshing section. In the direction, threshing by rotating the rotor, the culm after threshing is released to the field scene behind the fuselage, and the grains, straw chips, garbage, etc. leaking from the receiving net are arranged below the threshing section. The waste was separated by a sorting device, and straw debris and garbage were discharged from the rear of the machine, and the fines were stored in a Glen tank disposed on the side of the threshing unit. Then, when the Glen tank is full, it is configured to be able to be discharged to a truck bed or the like by a discharge auger arranged so as to be capable of turning and raising and lowering above the Glen tank.

[0003]

However, the conventional general-purpose combiner takes in a grain stalk by a reaping device, cuts the stem, and conveys the culm to the rear, and supplies it from the rear of the conveying device to the front end of the rotor of the threshing unit. And, taking in the grain culm at the front end of this rotor, the intake blade for sending to the threshing section was provided, and the conveying direction in which the grain culm is supplied,
Since the direction of the rotation axis of the take-in blade is substantially linear, the take-in / transport efficiency is reduced at the transfer portion, and as a result, the take-up blade is easily clogged.

Further, since the rotor is disposed long in the front-rear direction of the machine, and the Glen tank is disposed on the side thereof, the right and left weight balance is deteriorated. That is, when the work is started, the weight is biased toward the side where the threshing device and the sorting device are arranged because the Glen tank is empty.
On the other hand, as the harvesting operation progresses, grains are stored in the Glen tank, and when the grain is full, the center of gravity shifts to the Glen tank side. Therefore, at the start of the work and after the work has progressed, the left and right weight balance is different, so the steering feeling feels bad, and when the field scene is soft, the aircraft leans to the left and right and the cutting height may differ between the left and right. There was.

In order to discharge the grains in the Glen tank, the grains are discharged by a discharge auger. However, since the discharge auger is disposed horizontally above the Glen tank, it is discharged from a discharge conveyor below the Glen tank. The transport structure to the auger becomes complicated, and the support structure for turning the discharge auger needs to have an increased strength, which also causes an increase in weight.

[0006]

The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described. That is, in a general-purpose combine provided with a screw-type rotor at the rear of the mowing unit, the screw-type rotor is disposed in a direction perpendicular to the traveling direction and a plurality of the rotors are disposed in parallel in the front-rear direction. Is larger than the diameter of the rear rotor.

A Glen tank is arranged above the rotor, and a discharge auger is arranged on a side of the Glen tank.
The base of the discharge auger communicates with a discharge conveyor provided in a Glen tank, and the discharge auger protrudes forward. In addition, an engine is disposed at the rear of the rotor, a transmission case is disposed below the engine, and an output shaft of the engine protrudes to one side on the left and right sides, and the transmission case, the rotor, the sorting device, and the reaping device are cut from one side. -The transport device is driven.

The rear end of the feeder house 10 is communicated with a threshing inlet 12, and the rear portion of the feeder house 10 is
Is supported so as to be able to move up and down freely. A hydraulic cylinder 14 is interposed between the lower surface of the feeder house 10 and the machine frame 13 of the machine, so that the mowing device 8 can be moved up and down. A driver's seat 15 is located above the feeder house 10.
And a cabin 17 that accommodates the steering handle 16 and the like. The cabin 17 is arranged at an upper position in front of the right, left, and center of the fuselage to improve visibility, facilitate checking of a mowing position, and improve steering operability. ing.

A threshing unit 18 is provided at the upper front of the fuselage. As shown in FIGS. 4 and 5, the threshing unit 18 includes a plurality of rotors (first rotor 21 and second rotor 22) and a receiving net. 20 and the like, and the first rotor 21 and the second rotor 22 are formed in a screw type having screw blades 21a and 22a provided on the outer periphery of a cylinder, and their axes are directed in the left-right horizontal direction and are arranged in front and rear parallel. The diameter of the first rotor 21 is larger than the diameter of the second rotor 22. In this embodiment, two rotors are arranged, but three or more rotors may be arranged to extend the threshing distance. In this embodiment, a feeder house 10 and a threshing inlet 12 are provided on the left side in the traveling direction of the aircraft, and the threshing inlet 12 is provided.
Are arranged at the left front of the first rotor 21 so that the grain stem is conveyed to the right by the rotation of the first rotor 21.
A partition plate 23 is provided between the first rotor 21 and the second rotor 22, and a rear plate 24 is provided at a rear portion of the second rotor 22 in a left-right direction, and a communication hole is provided on a right side of the partition plate 23. 23a is opened, and a discharge hole 24a is opened on the left side of the rear plate 24.

In such a configuration, when the harvested culm is sent from the feeder house 10 to the threshing inlet 12, the rotation of the first rotor 21 causes the harvested culm to be transported rightward and threshed. Then, when reaching the right end of the first rotor 21, it is sent from the communication hole 23 a to the threshing space of the second rotor 22, is threshed while being conveyed to the left by the rotation of the second rotor 22, and When sent, the culm falls from the discharge hole 24a onto the rear part of the sorting device 19 and is discharged onto the field.

By arranging the first rotor 21 and the second rotor 22 in a direction perpendicular to the traveling direction, the length of the body in the front-rear direction can be reduced, and the supply direction of the grain stalk and the first rotor 21 and the second rotor 22 can be reduced. The direction of the rotation axis of the rotor 21 is a right angle direction, and the first rotor 21 can be conveyed rightward by the screw blade 21a without providing the intake blade.
The culm is reciprocated in the left and right direction by the first rotor 21 and the second rotor 22 to increase the processing length,
The processing distance required for threshing is obtained.
Furthermore, by making the diameters of the first rotor 21 and the second rotor 22 different, the large-diameter first rotor 21 makes it easier to take in the grain culm, so that transport and threshing can be simultaneously processed in large quantities. . Then, since the untreated portion such as stabbing grains remains in the grain culm after the grain has been roughly shed, the remaining paddy is finely shed by the small-diameter second rotor 22.
