Intelligent seeder for tray nursing seedlings

Abstract

The invention provides an intelligent seeder for tray nursing seedlings. The seeder comprises a camera, a vision detection system, a seedling tray, a trapeziform seed-filling mechanism, a point-to-point control mechanism and a frame, wherein the camera is arranged on the lower part of the vision detection system; the vision detection system is arranged on the front part of the frame; the point-to-point control mechanism is arranged on the rear part of the frame; the trapeziform seed-filling mechanism is placed under the point-to-point control mechanism, and connected with the frame; the seedling tray passes through the trapeziform seed-filling mechanism, and is arranged under the camera and the point-to-point control mechanism. The planting principle of human is simulated, a monocular zooming camera is used as an eye, the vision detection system is used as a brain, and the point-to-point control mechanism executes planting actions of hands, so that the aim of tray nursing intelligent seedling for paddy, vegetables and the like is realized.

Description

(1) Technical field [0001] The invention relates to a seedling tray seedling seeding device, in particular to an intelligent rice seedling tray seedling seeding device. (2) Background technology [0002] Super hybrid rice is a new type of rice with good quality and high yield. It has been popularized and applied in a large area in my country. The precision seeding of its seedling tray requires 2±1 grains / hole. At present, the performance of the seed metering device can reach 1-3 grains / hole. However, the single seed rate is high (more than 20%), and there are cavities. Because of the influence of germination rate, seedling rate, blanketing property and seedling damage rate, the result cannot reach the planting requirements of 1 to 2 plants / clump. Therefore, according to Zhu Defeng, Xu Yicheng and others of the China Rice Research Institute proposed the seedling raising requirements of "low sowing rate to strengthen seedlings and form blankets". [0003] So far, there have bee...

AI Technical Summary

Problems solved by technology

The mechanical sowing level of super hybrid rice with traditional domestic seed metering devices has reached 2±1 grains / hole (seeding area), but there are still too many single grains, and the blanketing property is very poor, all of which cannot reach 2-3 grains / hole (seeding area) high-level precision sowing target, and the biggest defect is that it is impossible to avoid holes

In terms of new technology research, the "analysis and treatment of seedling tray seeding quality" has not yet been involved, the online control of seed supply and "hole grain number" has not been realized, and the hole problem has not been effectively solved
