Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking type rice transplanter equipped with a preliminary seedling placing device and a fertilizer applying device.

[0002]

2. Description of the Related Art A walk-behind rice transplanter equipped with a fertilizer applicator equipped with a spare seedling placing device is, for example, as shown in Japanese Utility Model Laid-Open No. 60-185421, a spare seedling is placed between left and right traveling wheels. In some cases, the placing device is fixedly arranged, and the fertilizer tank of the fertilizer applying device is installed above the traveling wheels.

[0003]

With the above construction, since the weight of the spare seedling and the weight of the fertilizer act near the axle, these weights do not impair the front-rear weight balance of the body, and the stability of the body is improved. However, since the preliminary seedling placing device is fixed, in order to take out the preliminary seedlings from the control position behind the aircraft, it is necessary to reach a large distance forward over the seedling placing table. It was often troublesome. The present invention has been made paying attention to such a point, and facilitates the taking out of seedlings from the preliminary seedling placing device, and reduces the labor at the time of fertilizer replenishment work by utilizing the structure. , With the aim of improving the handleability. Further, since the upper end of the fertilizer tank is at a high position, it was necessary to raise the fertilizer bag or container and support it by hand while supplying fertilizer. In practice, a fertilizer bag or container may be temporarily placed on the edge of the fertilizer tank to reduce the strain on the hand, but since a fertilizer tank is generally made of a lightweight plastic material, There is a risk that the fertilizer tank will be damaged if the load on the rim is applied incorrectly, so it was necessary to carefully perform fertilizer replenishment work.

[0004]

In order to achieve the above object, a walk-behind rice transplanter with a fertilizer application device according to the present invention has a fertilizer tank of the fertilizer application device provided in the front-rear direction in the vicinity of an axle of a traveling wheel and at the top of the machine body. In a walk-behind rice transplanter with a fertilizer application equipped with a preliminary seedling setting device, above the fertilizer tank, the preliminary seedling setting device is provided so as to be movable back and forth via a guide rail, and the guide rail is used for the fertilizer. The structure was set up near the upper end of the tank. Further, in order to achieve the above-mentioned object, the front-back movement range of the preliminary seedling placing device on the guide rail is
The seedling stand support frame located in front of the rear edge of the upper end opening of the fertilizer tank at the position where the preliminary seedling placing device moves to the front side, the auxiliary seedling placing device moves to the rear side along with the movement to the rear side. It is advisable to set it in a range that deviates rearward from the upper end opening position of the fertilizer tank. For the same purpose, a pair of left and right guide rails for guiding the preliminary seedling placing device so as to be movable back and forth,
The fertilizer tank may be disposed above the fertilizer tank, and the front end portions of the left and right guide rails may be connected to each other by a bridge portion.

[0005]

[Advantage] According to the above configuration, the preliminary seedling placing device is located near the fertilizer tank during planting to maintain the front-rear weight balance of the machine body, and when the preliminary seedling is taken out, the preliminary seedling placing device is slid backward to be installed from the rear of the machine body. Facilitates seedling removal. When replenishing fertilizer to the fertilizer tank, move the preliminary seedling placing device backwards to open the guide rail part near the upper end of the fertilizer tank, and place the fertilizer bag or supply container on this empty guide rail part to make it heavy. Supplying fertilizer from the opening at the top of the fertilizer tank without the need to hold the fertilizer bag or supply container while supplying it and the total weight of the fertilizer does not directly affect the top of the fertilizer tank. You can Further, as described in claim 2, the front and rear movement range of the preliminary seedling placing device on the guide rail is defined by the seedling stand supporting frame of the preliminary seedling placing device,
If the range is set to the rear side of the upper end opening position of the fertilizer tank with the movement of the spare seedling placing device to the rear side, the spare seedling placing device is moved backward when the fertilizer is replenished. Since the upper end opening of the fertilizer tank is not obstructed by the placing device portion, the replenishment work can be easily performed at this point. Further, the wheels are located on the side of the guide rail on the side of the fertilizer tank, and the distance from the worker on the side of the wheels to the fertilizer tank or the guide rail tends to be large. As described above, by providing a bridge portion that connects the front end portions of the left and right guide rails, the worker does not stick to the wheel lateral position, but is located in front of the wheel avoiding the wheel position, and the tank, the guide rail, and the bridge are located. Fertilizer replenishment work can be performed while approaching the part. Therefore, it is possible to more easily perform the supply operation with the fertilizer bag or the like placed on the guide rail or the bridge portion at the approaching position. Further, the strength of the guide rails is improved by connecting the left and right guide rails by the bridge portion.

[0006]

As a result, at the time of taking out the preliminary seedlings, the preliminary seedlings can be easily taken out from the rear of the machine body, and the guide rail for supporting the preliminary seedling placing device so as to be movable back and forth can be used as a fertilizer weight supporting member at the time of supplying the fertilizer. The fertilizer can be used and the fertilizer can be replenished with less effort without imposing an excessive load on the fertilizer tank. By adopting the configuration described in claim 2, it is possible to easily perform the fertilizer replenishment work into the fertilizer tank without being hindered by the existence of the preliminary seedling placing device.
By adopting the configuration according to claim 3, since not only the left and right guide rail portions that support the preliminary seedling placing device so as to be able to move back and forth, but also the bridge portion can be used as a fertilizer weight supporting member when replenishing fertilizer, It is possible to expand the range that can support the weight of fertilizer when supplying fertilizer. Therefore, if the front bridge portion of the guide rail is used, fertilizer can be supplied more easily without hindering the existence of the wheels, and the strength of the guide rail can be improved at the bridge portion.
