Transplanting appts.

Abstract

A transplanting device is provided to transplant seedlings to paddy fields and dry fields in multiple groups by a seedling transplanter attached to the left and right of a rotating body and to achieve lightweight effect and cost reduction due to a decreased number of parts. A seedling transplanter(26) is attached to the left and right of a rotary case(21) rotating around a horizontal rotational center line. A horizontal final axis(25) is freely rotatably disposed at a position deviated relative to the rotational center line in the rotary body rotating around the horizontal rotational central line. The seedling transplanter is attached integral to projecting portions protruded to the left and right from the rotary case on the final axis. Counter gears(37,38) are interposed from an intermediate gear(36) disposed on the rotary case to be electrically driven by a final gear(39) rotating integral with the final axis and rotate the final gear in a reverse direction of the rotary case.

Description

technical field [0001] The invention relates to the technical field of a rice transplanting device. The rice transplanting device is transported to the surface of a field for transplanting rice seedlings in a state of holding seedlings through a rice transplanting tool. Background technique [0002] Conventionally, in a seedling transplanting machine such as a rice transplanter, the drive rotation of a drive shaft protruding from a transmission case in the left and right direction is at a position offset from the rotation center of a rotation case integrally rotating with the drive shaft. , the terminal gear is provided, and the terminal gear is rotated in the opposite direction relative to the rotary box, and simultaneously rotates integrally with the terminal gear, and the rice transplanting device constituted by being provided with a rice transplanting tool is provided. The rice transplanting device moves the rice transplanting tool up and down reciprocatingly through the...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned conventional rice transplanting device is owing to all being provided with rotating box on each rice transplanting lane, so in the seedling transplanting machine that has a plurality of rice planting lanes, the number of rotating box increases, in addition, along with the number of rotating box is many, including intermediate gear, The number of parts of gears such as countershaft gears and final gears has also increased, and the weight has increased, which has become an important cause of cost increases.

[0007] In addition, although it can be considered that on the left and right sides of the rotary box, a transmission shaft that is integrally rotated with the terminal gear is extended, and a plurality of rice transplanting tools are installed on the transmission shaft, side by side, through a single rotary box, multiple lanes of rice transplanting The tool operates, but because it should span the part of the transmission shaft extending from side to side between the rice transplanting lanes, or to make the movement of the rice transplanting tool unstable, or to prevent the transmission shaft from interfering with the surrounding structures, there are other structures The degree of freedom in the design of piping, etc. of objects may be reduced, or the cost may increase

[0008] In addition, if the rice transplanting device considers improving the rotation transmission accuracy of the final gear based on the gears in the rotary box or reducing the looseness of the final gear due to the backlash of the gears, the axial clearance of the mutual gears for transmission is at a certain level. It is necessary to a certain extent, but because the axes of the intermediate gear, the countershaft gear, and the final gear are located on a straight line with each other in a side view, the rotation box increases in the direction of the arrangement of the axes, and there is a limit to the miniaturization of the rotation box
