Problems solved by technology

However, in the drum sowing process, it is easy to have only one seed or a hole in the missing seeding phenomenon, so the mechanical missing seeding phenomenon of the tray-type seedlings also constrains the development of horticultural mechanization

Embodiment Construction

[0033] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementations.

[0034] like Figures 1~3 Shown is a machine vision-based device for detecting and reseeding missing planting of a plug-type seedling raising machine, comprising a loading table, a drum-type seed metering device and an information collector, which are installed on the loading table and are sequentially arranged along the movement direction of the plug tray. And the missed sowing replanting mechanism, the seed outlet of the drum type seed metering device and the seed outlet of the missed sowing replanting mechanism correspond to the seed holes of the plug tray 10 respectively. The loading table is also equipped with a conveyor chain 18 that drives the movement of the plug tray, and a positioning baffle 11 adapted to the plug tray. The conveyor chain 18 drives the plug tray 10 to move forward at a constant speed, and the positionin...

Abstract

The invention relates to a device and a method for miss-seeding detection and reseeding of a plug-type seedling machine based on machine vision, and the device comprises a loading platform, and a drum-type seed metering device, an information collector and a miss-seeding reseeding mechanism which are sequentially arranged along the moving direction of a plug, a seed outlet of the drum-type seed metering device and a seed outlet of the miss-seeding reseeding mechanism respectively correspond to seed holes of the hole tray, and the information collector is used for collecting position information of the hole tray and miss-seeding information in the seed holes of the hole tray. The miss-seeding information in the hole tray is collected through the information collector, the miss-seeding reseeding mechanism is used for reseeding the miss-seeding seed holes, hole tray conveying, accurate seed metering, miss-seeding identification and accurate reseeding can be completed at a time, the full-seeding planting agronomic requirement of the hole tray type seedling raising machine is met, and the production efficiency is improved. Due to the intensive design, the occupied space and size are greatly reduced, the integrality is high, and mechanical, intelligent and precise reseeding of the plug type seedling raising machine is met.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a machine vision-based device and method for detecting missed seeding and reseeding of a plug-type seedling raising machine. Background technique [0002] The method of plug seedling raising is a new seedling raising technology that appeared and developed abroad in the 1970s. It has the following characteristics: (1) A fixed number of seeds are sown in each hole, and the root system of the seedlings between the seed holes is completely divided; (2) In view of the fact that most vegetables and flower seeds are irregular in shape, the coating method is adopted. The seeds are changed into regular shapes, which are more suitable for mechanized sowing; therefore, for irregular-shaped seeds, large-scale and high-proportion coated seeds are used. (3) The matrix mixture is used to fill the seed holes, and the filling and compacting in the early stage and the handling and ...
