Description

[Detailed description of the invention] This invention is a rice planting method that uses a wheel track leveling tool installed behind the running wheels to level out the wheel tracks and prevent seedlings from being disturbed when planting at the rear. Regarding machines.

The purpose of this is to level out wheel marks and prevent disturbances in the planting posture of seedlings, and to ensure that a reliable leveling effect can be obtained regardless of changes in the hardness or softness of the muddy soil. At the same time, it is an object of the present invention to prevent the ground leveling tool from being accidentally damaged when moving backward or over a ridge by making it possible to easily and quickly store the ground leveling tool using extremely simple means.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The mission case 1 for vehicle speed change with the engine ElIc mounted on the front of the aircraft is connected, and the wheel transmission cases 3, 3, in which running wheels 2, 2 are rotatably attached to the left and right sides of the mission case 1, are attached to the horizontal axis. At the rear of the machine, a seedling platform 4, on which mat-shaped seedlings are loaded, is attached to the rear of the machine so that it can be moved back and forth from side to side, and a seedling planting claw 5 is moved back and forth in an oval trajectory. A float 6, which is long in the longitudinal direction of the fuselage, is connected to the fuselage so that the front end can freely swing up and down with the rear end as the center, and the float 6... The seedling planting section 7 is configured to be maintained at a constant height on the mud surface by the buoyancy of the wheels 2, 2 and the ground reaction force of the wheels 2, 2, so that the seedling planting section 7 can be planted while moving the machine using the traveling wheels 2, 2. The rice transplanter is equipped with a walking type rice transplanting machine that uses claws 5 to take out a seedling block from a mat-like seedling and plant it at a constant depth under the mud surface.

At the rear position of the left and right running wheels 2, 2, a ground leveling plate 8 formed of a plate spring is clamped and attached to a bracket 9 by an elastic piece 12a made of a stronger plate spring, and this bracket 9 is attached. Horizontal axis center X relative to the aircraft
This bracket 13 is rotatably attached to the housing and is a locking part fixed to a rear part of the fuselage with the elastic piece 10a and an imaginary vertical line passing through the horizontal axis X as a border. A coil spring 10b is provided between them, and the ground leveling plate 8 is rotated and biased downward to constitute the ground leveling tool 10, and as the aircraft advances, the tracks of the passage grooves of the wheels 2, 2 and the grooves formed therein are removed. The soil is planted by entering the periphery and leveling the groove marks to suppress the flow of mud in the planting section 7 to prevent disturbance of the seedling posture.

The mounting angle t of the handle 11 can be adjusted by using the elongated hole 'llb of the bracket N1a of the steering handle 11.

The flange portion 13a of the bracket 13 has a plurality of locking holes 13b having different distances from the horizontal axis X so as to change the amount of expansion of the coil spring 10b.
. . . is installed so that the biasing force of the ground leveling tool 10 against the mud surface can be changed by changing the position, thereby dealing with the hardness and softness of the mud and effectively leveling the wheel marks. The structure is such that the flow of mud in the seedling planting area T is suppressed to ensure that the seedlings are not tilted during planting.

Further, in addition to the bracket 13, a mudguard cover 14, which is fixed to the transmission case 12 on the front side of the fuselage, is provided with the ground leveling cover 14, which is fixed to the transmission case 12 on the front side of the aircraft, with the imaginary vertical line passing through the horizontal axis X as a border. A locking portion 15 is provided to change the biasing direction of the coil spring 10b so as to pull the lower end of the tool 10 upward and position it above the mud surface, thereby providing a rotational fulcrum for the ground leveling tool 10. Place the ground leveling tool 1 in the upper position.
0 can be flipped up backwards and upwards to be stored, thereby preventing accidental damage to the ground leveling tool 10 when going over a ridge or going backwards.
The structure is designed so as not to damage the field.

As shown in the above embodiments, the characteristic structure of the rice transplanter according to the present invention is that a wheel track leveling machine is installed at the rear of the running wheels and is configured to be able to swing freely around the horizontal axis of the machine body. A ground leveling tool is provided, and a spring is hung between the ground leveling tool and one of the locking parts arranged at three different positions on the machine body side, and one of the locking parts is One of the locking portions is set at a position where the biasing force of the spring is applied in a direction to press and bias the lower end of the ground leveling tool against the mud surface;
The other locking part is set at a position where a biasing force of a spring is applied in a direction to lift the lower end of the ground leveling tool from the mud surface, and the lower end of the ground leveling tool is maintained above the mud surface, By selectively hooking one end of the spring to the locking portion at this circumferential position, the ground leveling tool can be freely switched between a mud leveling action posture and a retracted posture; A plurality of locking holes having different distances from the horizontal axis are provided in one of the locking portions at a position where the lower end is pressed toward the mud surface to take a mud surface leveling action posture. The biasing force of the spring can be changed by changing the engagement of the spring with respect to the stop hole.

First, since the biasing force that biases the ground leveling tool to rotate downward can be changed and adjusted, by adjusting this biasing force,
It is possible to effectively level out the wheel marks by dealing with the hardness and softness of the muddy soil, to reliably prevent the seedlings from becoming misaligned during planting, and to mount the biasing spring to the machine body with ease. By the very simple means of changing the amount, the ground leveling tool can be stored easily and quickly, and it has become possible to prevent the ground leveling tool from being accidentally damaged when going backwards or going over a ridge.
