Corn seed grain directional positioning placement device and method for directional sowing

Abstract

The invention belongs to the technicalfield of machine vision. According to a corn seed grain directional positioning placement device and a method for directional sowing, through a feeding device and a conveying device, seed grains to be measured are fed periodically and are distributed on a conveyor belt at intervals; through a structural design of a direction-adjusted and faceted placement device, corn seed grains with different embryo surface directions can be respectively placed, and directions of tip ends of the corn seed grains are corrected, so that directional positioning placement is realized. Meanwhile, the external physical characteristics of the corn seed grains are detected and calculated, so that the accuracy of the directions of the tip ends can be greatly improved, conditions are provided for arrangement packaging and directional sowing of the corn seed grains in the later period, and a solution way is provided for realizing mechanically and automatically directional sowing of corns.

Description

technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a device and method for directional positioning and placement of corn seeds for directional sowing. Background technique [0002] Directional sowing of corn refers to controlling the spatial posture of the seed grains in the soil so that the germ faces are in the same direction, so that the leaves of the plants can be stretched in an orderly manner, and the effect of light and ventilation can be improved, which is of great significance for increasing the yield of corn per unit area. [0003] To achieve directional sowing of corn, the artificial seeding method was initially adopted, which was laborious and laborious, and the seeds were prone to move when covering the soil. Later, some scholars invented the artificial seed belt method. The seeds were pasted on the carrier in advance to form a seed belt, and then the seed belt was spread into the ditch to facilita...

AI Technical Summary

Problems solved by technology

At first, the production of the seed belt was done manually, and the initial labor investment was still relatively large

Some scholars in Sichuan invented a corn directional seeder by using the principle of hole-shaped seeding. This seeder has strict requirements on the sowing environment and the seeding efficiency is not high, but it has taken a qualitative step in the transformation from manual directional sowing to mechanization.

Looking at the research status at home and abroad, at present, the directional and orderly arrangement of corn seeds mainly depends on purely mechanical means to achieve positioning and orientation, and the requirements for the external dimensions of the seeds, mechanical structural parameters and the adaptability between the two are relatively high. But the pass rate is not high
