AI Technical Summary

Technical Problem

Existing rice transplanters are only suitable for a single planting scenario, with a limited scope of application, and cannot meet the different requirements for seedling spacing in different planting scenarios.

Method used

Design a rice transplanting device with wide and narrow spacing, including a bracket and wide and narrow spacing planting mechanisms. The bracket is equipped with seven staggered planting mechanisms. Four and three planting mechanisms are driven by the first and second drive mechanisms respectively to realize wide and narrow spacing seedling planting, which is suitable for different planting scenarios.

Benefits of technology

It enables the planting of seedlings with both wide and narrow spacing on the same rice transplanter, expanding its applicability and improving planting flexibility and efficiency.

Abstract

The utility model discloses a kind of wide narrow interval rice transplanter, solve the technical problem that the existing part of transplanter is only applicable to single planting scene, and the scope of application is small. Including bracket connected with outside tractor, and wide narrow interval planting mechanism is located on bracket. Wide narrow interval planting mechanism includes spacing is located on bracket for accommodating seedling's seedling carrying tray A and seedling carrying tray B, and seven staggered distribution is located on bracket for the seedling planting mechanism of seedling carrying tray A and seedling carrying tray B on seedling is inserted into paddy field. The utility model is simple in structure, scientific and reasonable in design, convenient to use, the utility model can carry out wide interval seedling planting, also can carry out narrow interval seedling planting, suitable for seedling wide interval planting scene and seedling narrow interval planting scene, compared with the existing part only applicable to single planting scene transplanter, the utility model is more widely used.
