Paddy-bud seeder

Abstract

The invention provides a paddy-bud seeder. The seeder consists of close slot-type electromagnetic vibration seed metering devices, an electric control type seeding mobile platform, a track frame and a direct-current power supply, wherein each close slot-type electromagnetic vibration seed metering device consists of a hopper type seed box, a seed metering disk, an electromagnet, a spring piece, aspring support, a controller and a control circuit; two close slot-type electromagnetic vibration seed metering devices are arranged on the top surface of the electric control type seeding mobile platform in parallel, and integrally arranged on the track frame; the electric control type seeding mobile platform consists of a platform frame, a front shaft, a rear shaft, a front support arm, a rear support arm, front wheels, rear wheels, a transmission gear, a direct-current gear motor and a controller; and the track frame consists of tracks, beams, support legs and wire holders and is a double track. The paddy-bud seeder has the advantages of uniform seeding, adjustable seeding speed, low seed-damaging rate and suitability for field operation; moreover, the paddy-bud seeder is matched with a slurry-mixing disc-type seedling technology.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a paddy seed seed planter. Background technique [0002] The traditional rice cultivation method in my country is manual transplanting of seedlings. This method has complex procedures, high labor intensity and low production efficiency, which seriously restricts the development of rice cultivation in China. At present, in order to improve this situation, the country has promoted the use of small rice transplanters in the south, which has greatly improved production efficiency. However, small rice transplanters have high requirements on the quality of seedlings, and the seedlings raised by ordinary seedling raising methods cannot meet the requirements. Both the industrialized seedling raising technology and the pulp-mixing disc seedling raising technology can meet the requirements of standardized rice seedling raising, but the former needs to establish a corresponding seedling raising f...

AI Technical Summary

Problems solved by technology

[0003] There are many types of rice seedling tray seeders in China, most of which are only suitable for plug-type seedling raising, and there are few types of seeder used for rice seedling tray sowing, and all of them have the problems of easy seed damage and low sowing uniformity

However, foreign related precision seeding equipment for rice buds is expensive, and it is difficult to promote and use them in my country.

Therefore, the current mixing pad seedling raising technology mainly adopts the method of manual seeding, the seeding quality is low, uneven, the quality of the seedlings is not high, it is difficult to meet the requirements of machine transplanting, which seriously affects the promotion and use of rice transplanters and the improvement of rice production
