Description

[Detailed Description of the Invention] Conventionally, walking type rice transplanters have been equipped with a wheel swing case on the machine body, with one end pivoted on the left and right sides of the machine body. A float connected to the left and right ends of the supporting operating rod and provided with vertical movement on the underside of the aircraft is used to lower the wheels when the ground pressure of the float 1..] -1- becomes high. If the ground pressure of the notebook becomes low, the wheels will be raised to maintain a constant ground contact of -7r+-1.Fu-1. is connected to the hydraulic bag hat, and the above is connected to the moving member and the operating ladle. In addition to interposing a hydraulic expansion and contraction mechanism in between, the river surface sliding bodies located on the left and right sides of the rear of the aircraft are pivoted to the left and right to move the OJ function, and the rolling attitude of the aircraft is balanced at -. However, it was inferior in its ability to follow the hardness and softness of OJ fields.

This invention connects the 41118 bar installed on the body of the rice transplanter to the linkage mechanism of the float and the hydraulic system via a spring that resists the upward movement of the float, and also connects the bar to the rice transplanter's body to resist the swinging of the rice transplanter. The purpose of the present invention is to provide a swing and rolling adjustment device for a rice transplanter that is connected via a spring that gives Examples of this invention will be described.

When the ground pressure acting on the body becomes higher than a predetermined value, the center float 0 (vertical rotor and horizontal rotor) rotates the actuating arm (3θ forward) and switches the swing valve θΦ. When the ground pressure of the center float (1 (J) reaches a predetermined value, the swing valve (1ψ is It is returned to the neutral position 1ηt.

Automatically controls vertical movement.

In short, this invention connects the wheel swing case, which has one end pivoted to the left and right sides of the fuselage, to the left and right ends of the operating arm that swings back and forth via a vertical axis to the front-back moving member of the hydraulic system installed in the fuselage. In addition, a hydraulic expansion and contraction mechanism is installed between the ground pressure of the float ←→, which is installed on one toe side of the aircraft so that it can move upward, and a Tamen sliding body is pivoted to the aircraft body so that it can swing from side to side. In order to eliminate the low link when the aircraft rolls on the Tamen sliding body, the hydraulic oscillation machine is connected to the hydraulic system so that Shigenobu can be moved up and down by activating ``4''. The connecting mechanism is connected to the float through a spring that resists the two axes, and the river surface slide body resists its swinging! Connected via a rising spring and adjusted 1. When planting rice in soft paddy fields by operating the bar, the vertical movement of the float and the left-right swing of the sliding body are sensitively transmitted to the hydraulic system; The motion is insensitively transmitted to the hydraulic system, allowing safe and stable rice planting without being affected by the hardness or softness of the paddy field.
