Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to an auxiliary seedling stand for a multi-row rice transplanter.

(b) Conventional technology Conventionally, as an auxiliary seedling stand for a rice transplanter, a bonnet extending from above the engine at the front of the machine to the inside of the left and right wheels was provided, and an auxiliary seedling stand was directly attached to the upper surface of the rear part of this bonnet to hold auxiliary seedlings. It is already known from Japanese Utility Model Application Publication No. 59-92622 that the stand and bonnet can be tilted up and down as a unit, and it is known from the Japanese Utility Model Publication No. 1987-92622 that the auxiliary seedling stand is fixed and supported on a post installed on the body. 59−
This was already proposed in Publication No. 1447.

In addition, a V-shaped support rod consisting of a single rod is fixed to the side of the machine, the upper part of the support rod is bent laterally, and the rear part of the spare seedling stand for one spare seedling is placed at the rear. There is also one that is rotatably attached to the support rod, and the front part is supported by the bend at the top of the front support rod.
This is already known from the publication No. 57-104814.

(c) Problems to be solved by the invention In the method of attaching the auxiliary seedling stand directly to the bonnet, if the bonnet is made of synthetic resin, six or more auxiliary seedlings can be mounted in a multi-row rice transplanter such as a six-row rice transplanter. If the weight of the auxiliary seedlings becomes large, there is a problem that the bonnet will be damaged.Also, the method of attaching the auxiliary seedling stand to a support set up on the machine requires that there is a gap between the top and bottom of the bonnet between the machine and the auxiliary seedling stand. Since it was necessary to provide a space to allow movement, the auxiliary seedling stand became abnormally high, which caused a problem in that the stability of the aircraft deteriorated.

Furthermore, with the method of supporting the auxiliary seedling stand with a single V-shaped support rod, even if it is installed on both sides of the machine, it can only hold two spare seedlings, and on top of that, only one seedling stand can be placed on the front and back. Because it was supported by support rods, it was extremely unstable in the front, rear, left and right directions, especially in the left and right directions.

(d) Means for solving the problem The present invention mounts the engine at the front of the aircraft, wheels are mounted on both sides of the middle part, and the bonnet extending from the top of the engine to the inside of the wheels is centered at the rear. In a rice transplanter that is installed to move up and down and has an auxiliary seedling stand installed at the upper part of the rear part of the bonnet, the auxiliary seedling stand is used to store a plurality of spare seedlings from the outer side of the upper part of the machine to the outer side of the other side. The front sides of this auxiliary seedling stand are arranged in a series to be placed in parallel, and the front sides of this auxiliary seedling stand are overlapped and removably locked to the upper ends of the pillars set up from the machine, and the rear sides are connected to the upper end of the planting section. An auxiliary seedling stand is attached to the upper ends of a pair of left and right rear columns that are located above and extend from the planting transmission case to both sides and are pivotally supported for forward and backward rotation on a cylindrical pipe in which a planting shaft is installed. The above-mentioned problem has been solved by supporting both rear sides of the bonnet with the cylindrical pipes so that the auxiliary seedling stand can move up and down following the bonnet.

(E) Operation When performing maintenance or inspection on the engine, the hydraulic system installed at the rear of the engine, the see-saw mechanism for the wheels, etc., disconnect the front support from the auxiliary seedling stand and lift the front part of the bonnet. The seedling stand is supported by a pair of right and left columns at the rear, and the entire seedling stand is tilted upward about the cylindrical pipe.

When performing work or storing the bonnet after completing the above maintenance inspection, tilt the bonnet downward.
The bonnet is tilted downward and set at a predetermined position, and the bases of the rear supports of the auxiliary seedling stand are tilted downward around the left and right cylindrical pipes, and when lowered to a predetermined position, they are placed on the front support. Supported.

The auxiliary seedling stands are arranged in a series from the outside of one side of the machine to the outside of the other side, so they can accommodate a large number of spare seedlings, and even in this state, the front part is closer to the rear than the base Since it is supported by strong cylindrical pipes on the left and right through a pair of widely spaced columns on the left and right, it can be stably supported not only in the front-back direction but also in the left-right direction.
