Abstract

PROBLEM TO BE SOLVED: To provide a combine in which structure is simplified, the front part of a machine body and the machine body side of a feeder house can be opened without detaching the feeder house and operability is improved by supporting one side of a bearings through a vertical spindle to the machine body so as to be freely rotated. SOLUTION: A feeder house 6 is freely attachably and detachably fitted through a pair of left and right bearings 20 and 21 to the front part of the machine body, and one of bearings 20 and 21 is supported through a vertical spindle 22 to the machine body so as to be freely rotated. In this case, these bearings 20 and 21 are arranged inside and outside the machine body, and the outside bearings 21 is freely rotated toward the machine body. Besides, it id preferable for this freely rotary bearing 21 to provide an axial supporting part 30, which is turned with the vertical spindle 22 as a center, at the lower part and to freely attachable and detachable fit the upper part through a fitting thread 14 to the machine body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for threshing rice culms such as rice, and more particularly to a combine in which a feeder house is detachably attached to the front part of a machine body.

[0002]

2. Description of the Related Art Conventionally, a feeder house in a combine is formed into a substantially rectangular tube shape with its front and rear parts opened, and is internally composed of an endless belt hung between a front rotary wheel and a rear rotary wheel. The conveyor is built in, and each end of the drive shaft in this conveyor is projected to the left and right sides, and these ends can be attached to and detached from both sides of the front part of the machine with the upper mounting screw and the lower mounting screw. The feeder house is supported by a pair of left and right mounted bearings, and the left and right bearings are removed by loosening the mounting screws to remove the feeder house from the machine body.

[0003]

However, the feeder house is formed of a metal plate in a substantially rectangular tube shape, and the inside thereof is provided with a conveyer conveyor extending from the front end portion to the rear end portion. Since the total weight is large, for example, when you want to open the front part of the machine by repairing the power transmission system part facing the front part of the machine, or when the grain culms are accumulated inside the feeder house, When removing the feeder house from the machine, such as when opening the feeder house side, it is necessary to remove all the mounting screws that attach the left and right bearings to the machine, which makes the removal work cumbersome. When the screw was removed, the load of the feeder house acted on the mounting screw being removed, which made it difficult to remove.

The present invention is mainly intended to utilize an existing support structure of a feeder house so that the front part of the machine and the machine side of the feeder house can be opened without removing the feeder house. To do.

[0005]

In order to achieve the above object, the present invention provides a feeder house 6 at the front of the machine body 1 through a pair of left and right bearings 20 and 21. In the combine which is detachably attached, one of the bearings 20 and 21 is rotatably supported with respect to the machine body 1 via a vertical support shaft 22.

According to the second aspect of the invention, even when the feeder house and the driver's seat are arranged in parallel on the left and right in the front part of the machine body, the front part of the machine body and the machine side of the feeder house can be opened. Therefore, the outer bearing 21 disposed outside the machine body 1 is made rotatable with respect to the machine body 1.

According to the third aspect of the present invention, the feeder house can be rotated with respect to the machine body, but in order to prevent rattling of the left and right bearings with respect to the machine body, a vertical support is provided below the rotatable bearing 21. A shaft support 30 that rotates about the shaft 22 is provided, and the upper part is attached to the mounting screw 14.
It was detachably attached to the machine body 1 via.

According to a fourth aspect of the present invention, the rotatable bearing 21 is provided in order to increase the withstand strength of the rotatable side bearing when the feeder house is rotated with respect to the machine body.
Shaft supporting portions 30, 30 that rotate about the vertical supporting shaft 22 are provided on the upper and lower portions of the shaft.

[0009]

According to the invention of claim 1, the bearing 2
Since one of 0 and 21 is rotatably supported to the machine body 1 via the vertical support shaft 22, even if all the bearings are not removed,
By removing the other side of the bearing, the feeder house 6
The vertical support shaft 22 of one of the bearings can be rotated as a fulcrum, and this rotation can open the front portion of the machine body 1 and the machine body 1 side of the feeder house 6. Therefore, the front part of the machine body and the machine body 1 side of the feeder house 6 can be opened by a simple operation of removing the other one of the bearings and rotating it with the vertical support shaft 22 of the one bearing as a fulcrum. Moreover, since the bearing that supports the feeder house 6 is used, the structure can be configured by only improving one bearing portion, and the cost can be reduced.

According to the second aspect of the present invention, by removing the inner bearing 20, the outer bearing 21 can be used without being disturbed by parts such as the driver's seat 10 disposed adjacent to the feeder house 6 on the left and right. Since the feeder house 6 can be rotated outward, even when the feeder house 6 and the driver's seat 10 are arranged side by side in the front part of the machine body 1, the front part of the machine body 1 and the feeder house It is possible to easily open the side of the machine body 1 of 6.

According to the third aspect of the present invention, since the upper portion of the rotatable bearing 21 is attached to the machine body 1 via the mounting screw 14, the left and right bearings 20 and 21 can be attached to the machine body 1 without play. The front part of the machine body 1 and the machine body 1 side of the feeder house 6 can be easily opened by a simple operation of loosening the upper mounting screw 14 and rotating the feeder house 6.

According to the fourth aspect of the invention, the rotatable bearing 21 is not fixed to the machine body 1 by the mounting screw 14 or the like,
Since the feeder house 6 can be attached to the machine body 1, only by removing the other bearing and rotating the feeder house 6, the front part of the machine body 1 and the machine body 1 of the feeder house 6
The side can be easily opened, and the strength of the rotatable bearing when the feeder house 6 is rotated with respect to the machine body 1 can be increased.
