Description

[Detailed Description of the Invention] The present invention is a planting device installed in a rice transplanter. Specifically, the invention includes a seedling tray that is movable laterally, and a portion of the seedling tray that is opposite to the seedling loading surface. A transverse feed shaft that can be forcibly reciprocated in the direction and swingable around its axis is connected to the transverse feed shaft in an integrated horizontal movement state through a bracket, and the transverse feed shaft and the placed seedlings are removed from the seedlings. A spring that is interlocked and integrally oscillated with a oscillating shaft on the side of the seedling tray for sending the seedlings to the exit side through a rod at the end of the shaft, and urges the oscillating shaft to swing in a direction opposite to feeding the seedlings. and a mechanism for swinging the transverse feed shaft in the seedling feeding direction each time the transverse feed shaft is located at both ends of a reciprocating path.

In conventional planting devices of this kind, the spring for swinging and biasing the swing shaft in the opposite direction to seedling feeding was composed of a torsion spring fitted onto the swing shaft. When using this method, the torsion spring cannot be fitted onto or removed from the swing shaft unless the pivot connection between the swing shaft and the rod is released, so the torsion spring may be damaged during use. The drawback was that it was extremely time consuming to replace the torsion spring due to wear and tear.

The purpose of the present invention is to overcome these conventional drawbacks.

The characteristic configuration of the planting device according to the present invention, which was taken to achieve the above object, is that the spring is located between the bracket and the rod, the transverse feed shaft, or the swing shaft in a state in which the spring is located laterally inside than the rod. It consists of an interposed coil spring.

The operation of the present invention having the above characteristic configuration is as follows.

Since the spring for urging the swing shaft to swing in the opposite direction is a coil spring, the coil spring can be freely attached and removed without disconnecting the swing shaft and the rod.

Since the above-mentioned coil spring is provided on one side of the seedling stand between the bracket and the rod or the transverse feed shaft or the swing axis, for example, the coil spring is arranged on the bottom surface of the seedling stand. The coil springs can be installed and removed from the outside side of the seedling stand without having to crawl under the seedling stand.

Since the coil spring is disposed on the lateral inner side of the rod, the rod can act as a protector for the coil spring.

Therefore, according to the present invention, even with simple improvements to the spring, the spring can be replaced very easily.
This can be done quickly and has the effect of preventing damage caused by contact between the spring and the object.

Hereinafter, embodiments of the configuration of the present invention will be described based on the drawings.
