BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a seedling table in a transplanter that supports the seedling table above a main frame of a seedling planting section.

[0002]

2. Description of the Related Art In general, in a transplanting machine such as a riding rice transplanter, a planter which supports a seedling mounting table which is laterally fed above and below a main frame of a seedling planting section and which operates to plant the plant when the machine is running has a seedling. 2. Description of the Related Art There is known a method in which a seedling placed on a mounting table is scraped and planted in a field.

Conventionally, in such a transplanter, the seedling table is supported from below by a support frame erected at the seedling mounting section. However, if the supporting state of the seedling table is unstable, the seedling mounting accuracy is low. Therefore, it is necessary to strengthen the support frame to stably support the seedling mounting table. However, if the supporting frame is formed of a thick member in order to maintain the strength of the supporting frame, there is a problem that the weight of the entire seedling planting portion increases.

The support frame of the seedling mounting table is erected and fixed on the front, and a reinforcing member is formed between the support frame and the main frame so as to be inclined to form a triangular reinforcing portion in a side view. It is characterized in that the supporting frame can be supported in a stable state by increasing the strength of the support frame without being formed of a particularly thick member, and the seedling mounting table is provided above the main frame of the seedling planting section. In the supported transplanter, the main frame is formed of a square pipe, a support frame of a seedling mounting stand is erected and fixed on the front surface of the main frame, and a reinforcing portion is provided between the support frame and the main frame. By obliquely forming the reinforcing portion having a triangular shape in a side view, and by forming the reinforcing member with a thin plate having elasticity, even if an excessive force acts on the reinforced support frame, The present invention is characterized in that the stress can be buffered by the elasticity of the reinforcing member, and that the reinforcing portion having a triangular shape can also be used for mounting components.
