Description

Rice Seedling Tray Seedling Raising Precision Seeder

technical field

The utility model relates to a seeder, in particular to a precision seeder for rice seedling tray seedling raising.

Background technique

With the continuous development and improvement of rice varieties, rice planting methods have presented various forms. In order to adapt to the new rice planting methods, rice planting mechanization has also developed greatly in our country, among which rice transplanting mechanization is the main one, so the development of rice seedling raising Machinery adapted to the development of rice production. Although the rice seedling-raising techniques of different varieties are basically similar, that is, the operations of laying the bottom soil, sowing, covering soil, cleaning, and watering are used; grains/hole (grid), hybrid rice seedlings usually require 3 to 5 grains/hole (grid), while super rice requires 1 to 2 plants/hole (grid). Therefore, with the continuous development and improvement of rice varieties, the seedling and sowing methods have changed from traditional drill or broadcast to hole sowing and precision sowing. At present, the crops involved in precision seedling cultivation include vegetables, flowers, and Chinese herbal medicines.

Abroad, since the 1970s, Japan and South Korea have started industrialized seedling raising, not only developing relatively complete models in vegetables and flowers, but also developing a complete set of rice seedling raising production lines. For example, Jingguan, Kubota, Mitsubishi and other companies all have their own seedling seeders, which are exquisite in technology and high in automation, but expensive, and most of these production lines are aimed at ordinary rice seedlings, which can achieve 2 to 5 grains/hole (grid) ) of the fine amount of sowing. The principle of the sowing parts they adopt is mainly mechanical (groove and socket). The level of seedling raising technology in South Korea is close to that of Japan, but more seedling raising technologies are used for vegetables and economic crops. So far, foreign countries have not yet seen the practical results of the industrialized seedling raising technology for super rice. Europe and the United States already have a variety of seedling raising and seeding production lines, such as B1ackmore System, Marksman, SpeedlingSystem, etc., with full functions and high degree of automation, but they are mainly used for greenhouse seedling raising and seeding of vegetables, flowers and other plants, and the equipment generally uses suction needles Type, 1 to 5 grains per hole (grid), the work quality is better, but the cost is high and the productivity is low.

Domestically, the mechanized seedling raising equipment has been developed since the 1980s. In the early days, conventional rice generally used the traditional mechanical seeder as the core technology of the rice seedling raising and sowing line, which has the characteristics of simple structure and high efficiency, but it uses a large amount of seeds. The injury is serious. At present, vibrating or pneumatic seeders are mainly used. The vibrating seed metering device has a simple structure and less damage to the seeds, which can meet the precision and small amount of sowing of hybrid rice, but the seeding accuracy is not high, and the existing seed metering devices cannot meet the precision requirements. For sowing requirements, the pneumatic seed metering device has good sowing accuracy, but it has the characteristics of high price, clogged suction holes, and low productivity. In addition, the existing sowing assembly line is generally only suitable for a single type of seedling tray, and the adjustability of the sowing rate is relatively poor, so it is difficult to adapt to the sowing requirements of different types of seedling trays and the sowing accuracy requirements of different rice varieties.
