Device for automatically supplying and strickling seed of rice disk-sowing seedling-raising system

Abstract

The present invention discloses a seed automatic compensating and strickling device of the rice tray-seeding seedling-culture system. A seed tray is round; the bottom of the seed tray is provided with a concave rectangular groove seed collector; the upper surface of the seed collector is leveled to the surface of the seed tray; the bottom of the seed collector is a uniformly-distributed porous structure; a motor is arranged at the lower side at the center of the bottom of the seed tray; an output shaft of the motor passes through the center of the bottom of the seed tray to be rigidly connected with a strickling device arranged on the upper side at the center of the bottom of the seed tray; the strickling device can be rotary inside the seed tray under the driving of the motor; the seed tray, the motor and a seed box are fixed on the stander; a seed box is arranged above the strickling device; a seeding switch is arranged at the lower end of the seed box; the seeding switch is connected with an air cylinder. The present invention not only can provide a leveling and uniform layer of the seed for the rice tray-seeding seedling-culture system to make the planting absorption head easy to absorb the seed, but also can promptly, precisely and automatically compensate the seed to the seed tray; moreover, the seed compensation and the strickling process are automatically controlled; therefore, the efficiency of the system is high.

Description

technical field [0001] The invention relates to an automatic seed supply and scraping device for a rice disc sowing and seedling raising system, which is used to provide a flat and uniform seed thin layer for the seed suction head of the rice disc sowing and seedling raising system, so that the seeding suction head can evenly suck up the seeds, and at the same time Automatically replenish seeds for the seed plate precision. Background technique [0002] At present, rice sowing mainly includes hole sowing and drill sowing. However, the structure of the above-mentioned sowing method is complicated, the seeding rate and seed spacing are not easy to control, the degree of automation and work efficiency of the system are low, and the labor intensity is high. Therefore, it is very necessary to develop a disc sowing seeding system with precise control of seeding rate, precise control of seed spacing, high degree of automation, fast sowing speed and the ability to adapt to the requi...
