Abstract

The invention relates to a rice seedling sowing mechanism matched with a rice seedling sowing machine with stepless and rapidly-adjustable row space. The rice seedling sowing mechanism comprises a seedling collecting bucket, a seedling placing device, a rice nutritional bowl box plate, and a rice seedling grabbing mechanism. The rice nutritional bowl box plate and the rice seedling grabbing mechanism are arranged above the seedling collecting bucket. The seedling placing device is placed inside the seedling collecting bucket, and is provided with a step motor, a synchronous tooth-shaped belt, a synchronous tooth-shaped belt wheel, and two parallel synchronous conveying belts formed by flexible projections, wherein the flexible projections are uniformly arranged and fixed on the synchronous tooth-shaped belt. The rice seedling grabbing mechanism grabs the rice nutritional bowl placed on the rice nutrition bowl box plate, and places the rice nutritional bowl on the seedling collecting bucket between the two parallel synchronous conveying belts. The bottom of the seedling collecting bucket is provided with a seedling discharge port. The two parallel synchronous conveying belts with the flexible projections of the seedling placing device push the rice nutritional bowl on the seedling collecting bucket, such that the rice nutritional bowl glides to the seedling discharge port of the seedling collecting bucket so as to sow the seedling into the field. According to the present invention, the rice seedling sowing mechanism of the present invention has characteristics of stable operation, compact structure, and flexible operation, and is suitable for the rice sowing operation with characteristics of precise sowing and less seed injuring; and the requirements of precise sowing, accurate seed placing, cavity reducing and high efficiency can be met.

Description

technical field

[0001] The invention relates to a pot seedling planting mechanism matched with a pot seedling planting machine with stepless and fast row spacing adjustment, and belongs to the technical field of agricultural machinery. Background technique

[0002] In recent years, although the mechanization of rice planting has made great progress, the rate of mechanical transplanting is still only about 10%, which is still the bottleneck of agricultural mechanization. At present, my country's rice mechanized planting techniques mainly include throwing seedlings, swinging seedlings, dry direct seeding, and transplanting rice seedlings. The first three are all in the experimental demonstration stage, and they are still immature, and some have regional limitations. The technique of transplanting seedlings with seedling trays is a mature technique.

[0003] Blanket-shaped seedlings will damage the roots, but pot-shaped seedlings will basically not damage the roots. Facts have ...
