Method and device for automatic seeding of tobacco coated seed

Abstract

The invention discloses a method and a device for automatic seeding of tobacco coated seed. The method seeds automatically, utilizing a transmission machine to carry out nutrient medium panning, compaction, hole rolling, seeding, cracking and medium covering working procedures on a tobacco medium disc (9) by a control system. A nutrient medium panning machine (1) is arranged above the transmission machine at the panning stage; a vibrator (1.4) is arranged on the transmission machine, the terminal of the vibrator is provided with a scaler; a roller-path type indenter (2) is arranged above the transmission machine at the hole rolling stage, and a hole rolling positioner is arranged on the transmission machine; a roller-hole type seeder (3) is arranged above the transmission machine at the seeding stage, and a seeding positioner is arranged on the transmission machine; a water injection device (4) is arranged above the transmission machine at the cracking stage; and a medium covering machine (5) is arranged above the transmission machine at the medium covering stage. The working procedures of tobacco medium disc transmission and tobacco coated seed seedling of the transmission machine can be controlled by handwork or an automatic control system, therefore, the method can better realize centralized plastic-tent and industrialized tobacco seedling.

Description

technical field [0001] The invention relates to the technical field of tobacco sowing machinery, in particular to a method and device for automatic sowing of tobacco coated seeds for tobacco seedling cultivation. Background technique [0002] At present, the sowing method of tobacco seedlings at home and abroad is basically based on hole sowing in tobacco base trays. The basic situation of tobacco planting machinery is mainly due to the fact that there are many types of seeding machines abroad, and the introduction cost is high, and the volume is large and not suitable for China's national conditions. Mainly manual machinery, low labor efficiency, serious damage and waste of seed material, inaccurate and too many holes, which brings a lot of labor to the management of seedlings in the later period, and domestic tobacco seedlings have been concentrated in greenhouses and industrialized seedlings , Tobacco planters are obviously late, and there is an urgent need for a high-eff...
