Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter equipped with an auxiliary seedling platform on an extension of the seedling platform.

Generally, when the width of the sliding contact surface of the protrusion of the auxiliary seedling stand is formed to be narrower than the width of the sliding contact surface of the protrusion of the seedling stand, the connecting part of the protrusion sliding surface of the seedling stand The width of the contact surface protrudes from the width of the contact surface of the convex part of the auxiliary seedling platform, which creates resistance, which impedes the flow of the seedlings, and prevents the seedlings from moving down smoothly, resulting in a shortage of seedling supply. There were inconveniences such as missing plants and poor planting.

In view of the above-mentioned points, the present invention provides a seedling platform device for a rice transplanter in which an auxiliary seedling platform is installed in series on the extension line of the upper end of the seedling platform. The width of the sliding contact surface of the convex part of the auxiliary seedling support stand is larger than the sliding contact surface of the convex part of the seedling support stand, and the width of the sliding contact surface of the convex part of the auxiliary seedling support stand is within the range of the width. In addition to arranging the sliding surface of the corresponding convex part of the seedling stand,
The sliding contact surface of the convex part of the auxiliary seedling stand is flush with or higher than the sliding contact surface of the convex part of the seedling stand, and the sliding contact surface of each convex part is extended to the connecting part of each stand. By continuously joining the sliding contact surfaces of each convex part, the downward movement of the seedlings from the auxiliary seedling platform to the seedling platform is smooth without resistance, and the seedlings can be easily moved by the planting claws. It ensures the supply of seedlings to the extraction position and eliminates problems such as missing plants and poor planting.
It is an object of the present invention to provide a seedling stand device for a rice transplanter that improves planting performance and improves efficiency in planting work.
