Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and equipment, in particular to a rice planting uniform-speed stable seedling transplanting device. Background Art

[0002] A rice transplanter is an agricultural machine that plants rice seedlings in rice fields. When planting, a mechanical claw first takes out several rice seedlings from the seedbed and plants them in the soil in the field. In order to keep the angle between the seedbed and the ground at right angles, the front end of the mechanical claw must adopt an elliptical motion curve when moving.

[0003] Rice is generally planted in paddy fields, which have more soil and therefore are more uneven than ordinary fields. When traditional rice transplanters are inserting seedlings into paddy fields, too much or too little soil in a certain area of ​​the paddy field will make the transplanting quality of traditional rice transplanters unstable, resulting in uneven insertion depths of seedlings, which will cause crooked seedlings, fallen seedlings, or even floating seedlings, which will affect seedling development and reduce production. Utility Model Content
