Method of automatically adjusting a body of a tractor to a horizontal position and apparatus for performing the same
First Claim
1. A method of adjusting a body of a tractor to a horizontal position, the method comprising the steps of:
- (1) determining whether the tractor is in an automatic mode or in a manual mode;
(2) operating the tractor with the manual mode if the tractor is in the manual mode in step (1);
(3) determining whether the tractor is in a flat land or in a slope land if the tractor is in the automatic mode in step (1);
(4) adjusting a height of the body of the tractor with respect to the ground by operating a height button according to a ground condition if the tractor is in the flat land in step (3);
(5) determining a driving direction of the tractor if the tractor drives in the slope land in step (3);
(6) adjusting the body to the horizontal position by controlling the body in left and right directions thereof if the tractor is driving in a contour direction in step (5);
(7) adjusting the body to the horizontal position by controlling the body in front and rear directions thereof if the tractor is driving in a latitudinal direction in step (5); and
(8) adjusting the body to the horizontal position by controlling the body in left, right, front and rear directions thereof if the tractor is driving in an oblique direction in step (5).

Abstract
Disclosed is a method of adjusting a tractor to a horizontal position and an apparatus for performing the same. The method comprises the steps of determining whether or not the tractor is in an automatic mode, determining whether the tractor is in a flat land or in a slope land if the tractor is in the automatic mode, adjusting a height of the body with respect to a ground if the tractor is in the flat land, determining a driving direction of the tractor if the tractor is in the slope land, adjusting the body to the horizontal position by controlling the body in left and right directions thereof if the tractor is driving in a contour direction, adjusting the body to the horizontal position by controlling the body in front and rear directions thereof if the tractor is driving in a latitudinal direction, and adjusting the body to the horizontal position by controlling the body in front, rear, left and right directions thereof if the tractor is driving in an oblique direction. The body of the tractor can be maintained to the horizontal position while the tractor is driving and the height of the body with respect to the ground can be adjusted, so the crops can be prevented from being damaged. The apparatus can rapidly adjust the body of the tractor to the horizontal position.

5. An apparatus for adjusting a body of a tractor to a horizontal position, the apparatus comprising:
-
a driving circuit generating an electric signal for operating the body and a steering cylinder; a first hydraulic pressure supplying section connected to the driving circuit for controlling the body of the tractor; a second hydraulic pressure supplying section connected to the driving circuit for controlling a driving direction of the tractor; a front cylinder section including a first front wheel cylinder and a second front wheel cylinder, the front cylinder section being connected to the first hydraulic pressure supplying section, the first front wheel cylinder being disposed between a first idle gear portion which is rotatably coupled to a first end of a front wheel axle and a first end of a first bracket horizontally installed on a front portion of the body, the second front wheel cylinder being disposed between a second idle gear portion which is rotatably coupled to a second end of the front wheel axle and a second end of the first bracket; a rear cylinder section including a first rear wheel cylinder and a second rear wheel cylinder, the rear cylinder section being connected to the first hydraulic pressure supplying section, the first rear wheel cylinder being disposed between a third idle gear portion which is rotatably coupled to a first end of a rear wheel axle and a first end of a second bracket horizontally installed on a rear portion of the body, the second rear wheel cylinder being disposed between a fourth idle gear portion which is rotatably coupled to a second end of the rear wheel axle and a second end of the second bracket; a steering cylinder which is connected to second hydraulic pressure supplying section and is installed on a front portion of the front wheel axle; a slope detecting sensor provided at the body, the slope detecting sensor detecting an incline of the body according to a ground condition; cylinder displacement detecting sensors installed at both front and rear cylinder sections for detecting displacements thereof; and a microcomputer which is installed in the body and is connected to the cylinder displacement detecting sensors and the slope detecting sensor for controlling the operations of the steering cylinder and the front and rear cylinder sections. - View Dependent Claims (11, 12, 13, 14)
