A two-stage sinusoidal non-circular gear planetary system duckbill seedling planting mechanism with high verticality

Abstract

The invention discloses a high-verticality secondary sine non-circular gear planetary system duck-billed seedling planting mechanism. A seedling planting in the prior art cannot ensure the verticality of pot seedlings. Two sine non-circular gear planetary system transmission devices are symmetrically arranged at two ends of a central axle of the duck-billed seedling planting mechanism, and a duck-billed seeding nozzle is arranged at each of two ends of each sine non-circular gear planetary system transmission device; a planetary carrier moves along a transplanter, and the midpoint of the bottom edge of a main hopper forms a seedling planting track; the seedling planting track comprises a seedling receiving segment, a seedling transporting segment, a seedling segment and a resetting segment; the seedling segment comprises a hole inlet segment and a hole outlet segment; the bottom end of the seedling receiving segment is connected with the top end of the seedling transporting segment, the bottom end of the seedling transporting segment is connected with the top end of the hole inlet segment, the bottom end of the hole inlet segment is connected with the bottom end of the hole outlet segment, and the top end of the hole outlet segment is connected with the bottom end of the resetting segment; the projection of the hole outlet segment along the horizontal direction is 0-4mm, and the projection of the hole outlet segment along the vertical direction is 40-60mm. By adopting the duck-billed seedling planting mechanism, the verticality of transplanted pot seedlings can be ensured and the pot seedlings cannot be taken back or damaged.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a seedling planting mechanism, in particular to a duckbill type seedling planting mechanism with a high uprightness and a secondary sinusoidal non-circular gear planetary system. Background technique [0002] Transplanting is one of the development trends of crop planting. Transplanting has the comprehensive benefits of climate compensation and early growth. It can make full use of light and heat resources, and its economic and social benefits are very considerable. Due to the high cost of manual transplanting, realizing the mechanization of transplanting has become an urgent problem to be solved in my country's agricultural production. [0003] At present, the planting mouth track of the rotary duckbill seedling planting mechanism driven by the planetary gear system is a cycloid track, and the hole formed under the ridge surface is large during operation, so that th...
