Abstract: A multi-crop adaptive seed delivery and uniform seed distribution device, including: a seed storage box, a seed metering mechanism, a seed distributor lower housing, a seed distributor upper housing, and a blade driving mechanism. Closed accommodating cavity is formed between the seed distributor upper and lower housing; N seed guide tubes are arranged in circumferential direction, N being positive integer equal to or greater than 2; N blades are rotatably mounted in accommodating cavity; blades are arranged in vertical direction; closed independent seed guide cavity is divided in accommodating cavity by two adjacent blades; upper end of each seed guide tube is connected with corresponding seed guide cavity; top of seed distributor upper housing is divided into N fan-shaped areas in circumferential direction; upper end of each blade is connected to edge of corresponding fan-shaped area by means of elastic piece; and collision sensor is provided in each fan-shaped area.

Abstract: A directional garlic seed throwing mechanism includes a base, a rotating device, a vision sensor, a seed throwing guide plate, a seed guide pipe and a plurality of bulbil adjusting devices. The rotating device includes a rotating motor detachably connected to the base and a turntable connected to an output end of the rotating motor. The seed throwing guide plate is arranged on the turntable to enable garlic seeds of seed containing bowls to fall into the seed guide pipe. The seed guide pipe has an upper port right below the bulbil adjusting devices and arranged on the base. An even number of the bulbil adjusting devices are fixed on the turntable uniformly and symmetrically and include the seed containing bowls and bulbil direction control devices for driving the bowls to rotate 180 degrees.

Abstract: A motor-driven single-seed-ejection sowing device includes a housing, a seed metering roller, a seed brush, a seed metering mechanism and a power mechanism. The housing includes a power compartment and a seed compartment. The surface of the seed metering roller is provided with seed grooves having spaces for accommodating a single seed. The seed metering mechanism includes a spring, a striking tube, a piston and the piston tube. The piston and the piston tube are arranged for axial movement inside the striking tube. The power mechanism includes a control unit and a drive unit. The control unit includes the motor, the drive panel, the Hall sensor and the magnet. The magnet is set on the striking tube. The Hall sensor and the drive panel are connected to the motor, and the motor drives the seed metering roller and seed metering mechanism by the drive unit.
