Automatic digging device for young corn embryos

Abstract

The present invention relates to an automatic digging device for immature corn embryos, which belongs to the technical field of agricultural machinery automation, and in particular to a device for automatically digging young embryos of corn with four linkages. The automatic excavation device for young corn embryos includes: corn ears Rotary motor, corn ear rotating shaft, digging mechanism radial moving platform, digging motor, digging mechanism, corn ear, corn ear axial moving platform, axial moving motor, central processing unit, among which the digging mechanism is a plane four-connected Rod mechanism, including crank, connecting rod, rocker. It solves the problems of low efficiency and high intensity of manual extraction of immature corn embryos, realizes the adjustment of the connecting rod movement track and the position of the end of the connecting rod according to different varieties of corn, to replace the artificial embryo extraction method, and improves the adaptability of corn embryo extraction and flexibility, which improves the efficiency of extracting young corn embryos and reduces the work intensity of embryo extraction.

Description

technical field [0001] The invention relates to an automatic digging device for immature corn embryos, which belongs to the technical field of agricultural machinery automation, and in particular to an automatic digging device for young corn embryos with four links. Background technique [0002] Corn is a typical multi-purpose high-yielding crop. Although China is the second largest producer of corn in the world, it lacks high-quality corn seed varieties that are resistant to stress, disease, high combining ability and wide adaptability. Transgenic breeding is one of the important ways to improve maize varieties, and transgenic technology is the core technology of modern seed industry. Embryogenic callus induced by immature maize embryos is a widely used transgenic maize recipient type in the world. For corn immature embryos, 10-15 days after pollination, the immature embryos are located at the base of the corn near the small end, and when the length is 1-2 mm, the regenera...

AI Technical Summary

Problems solved by technology

At present, a medium-sized laboratory needs about 400,000 to 500,000 corn ears for embryo extraction each year. Based on the calculation of 300 kernels per corn ear, the approximate amount of embryos to be extracted is 120 to 150 million per year. However, the extraction of young corn embryos Work is mostly manual

The mainstream manual embryo extraction method is to sterilize the surface of the corn ear with 75% alcohol, peel off the seed coat, and pick out the young embryos. It is necessary to pick out all the embryos in the corn kernels on the entire ear, which greatly reduces the cost of embryo extraction. The efficiency and increase the strength of manual embryo extraction, resulting in a large amount of manpower for manual embryo extraction every year. Therefore, it is of great significance to explore a mechanical operation method to replace manual embryo extraction.
