Abstract
The invention discloses a precision planter which comprises a frame assembly, a wheel assembly, a seed circulating assembly as well as an air seed discharging and sowing assembly. During sowing operations, a wheel drives a trigger switch wheel to rotate so that a current loop formed among a storage cell, a switching device and an air gun is frequently closed and instantly communicated; when the switch is not contacted with a protrusion or a non-ferrous metal block, a circuit is switched off and the air gun is under a closed state, then the seeds flow into a seed collection box from a seed box through a seed discharging channel; when the switch is contacted with the projection or the non-ferrous metal block, the circuit is switched on and the air gun works to blow a seed continuously flowing in the seed discharging channel into a sowing tube to realize single-seed precise sowing. The precision planter can be used for precisely sowing seeds of middle and small sized crops like millets, mung beans and vegetables by adjusting the width of the exhaust port of the air gun and the seed discharging channel. The precision planter has a simple structure and is most convenient when a tractor is adopted for power; moreover, other powers can also be used as a power source after the storage cell and an air source are additionally arranged on the planter.
