Attitude control device for combine harvester and work machine

Abstract

The invention provides a combined harvester, in which a grain delivery cylinder freely moving along the vertical and horizontal direction can be operated under the horizontal position and the operation structure can be simplified. A swinging range of the grain delivery cylinder (70) in the vertical direction is such arranged that the shaft center of the grain delivery cylinder (70) can alter fromthe downward state to the upward state, and the rotating range of the grain delivery cylinder (70) in the horizontal direction comprises a rotating angle range of a region on an automatically advancing body.; The combined harvester has a guide body (45) moving above the automatically advancing body (1) with the grain delivery cylinder (70) in the rotating angle range corresponding to the region onthe automatically advancing body (1) in the rotating range of the grain delivery cylinder (70) around the horizontal direction of the top and bottom shaft center to guide to lift the grain delivery cylinder (70) in the downward state upwards.

Description

[0001] This application is a divisional application of the earlier application (application date: April 30, 2009, application number: 200910137942.3, invention name: combine harvester). technical field [0002] The present invention relates to a combine harvester comprising a grain tank on one lateral side on the rear side of a self-propelled body, and the grains taken out from the lower end side of the grain tank are lifted upward and vertically and horizontally. The grain is discharged from the front end of the freely movable grain delivery cylinder. Background technique [0003] In the combine harvester of the structure which discharges the grain in a grain tank from the front-end|tip of a grain delivery cylinder as mentioned above, it is generally comprised so that a grain delivery cylinder may move up and down and rotate horizontally above a horizontal position, but In this case, since it is inconvenient to carry out the work which puts a grain into a rice bag on the gr...

Problems solved by technology

[0006] However, in the structure of this conventional structure, it is necessary to detect the angle sensor of the rotation angle on the horizontal direction of the above-mentioned grain delivery cylinder and the swing angle on the up-down direction respectively, and it is necessary to use the detection value based on this angle sensor to accurately An actuator for operating the grain delivery cylinder, a control device for switching these actuators to a state where the operation is restricted and a state where the operation is not restricted based on the detection value of the above-mentioned angle sensor, and a display mechanism for indicating the restricted state etc., with a more complex structure
