Precision sowing device for rice pot seedling raising

A precision sowing device for rice pot seedling raising, comprising:

• a rack used to be arranged above a transmission device;
• a seed storage mechanism, fixedly arranged on the rack, wherein the seed storage mechanism is provided with a seed storage trough;
• a seed suction mechanism, comprising a seed suction cylinder, and a circulation assembly, wherein the seed suction cylinder is rotatably connected to the rack, and provided with a plurality of suction nozzles communicating with an inside of the seed suction cylinder, the circulation assembly runs through the seed suction cylinder in an axial direction and communicates with each suction nozzle, the circulation assembly is provided with an air inlet and an air outlet, the air inlet is used for introducing a gas to make an air pressure in the circulation assembly lower than that outside the seed suction cylinder, such that each suction nozzle is able to adsorb seeds, and rice awns are able to be sucked into the circulation assembly and then discharged through the air outlet;
• a sowing mechanism, comprising a sowing cylinder rotatably arranged on the rack, wherein the sowing cylinder is arranged on one side of the seed suction cylinder and axially parallel, and an outer wall of the sowing cylinder is provided with a plurality of sowing troughs, and the sowing troughs are in a one-to-one correspondence to the plurality of suction nozzles;
• and
• a driving mechanism, arranged on the rack, and connected to the seed suction cylinder and the sowing cylinder, wherein the driving mechanism is used to drive the seed suction cylinder and the sowing cylinder to rotate in the same direction clockwise or counterclockwise around axes thereof, enabling an inner wall of the sowing trough to scrape seeds on the suction nozzle into the sowing trough.
