Multi-crop adaptive seed delivery and uniform seed distribution device

A multi-crop adaptive seed delivery and uniform seed distribution device, comprising:

• a seed storage box, configured to store seeds, a seed metering box being connected in a closed manner below the seed storage box;
• a seed metering mechanism, provided in a connection of the seed metering box and the seed storage box, wherein the seed metering mechanism quantitatively delivers the seeds in the seed storage box to the seed metering box, an inlet end on one side of the seed metering box is connected to an electric fan, and an outlet end on an other side of the seed metering box is connected to a delivery tube;
• a seed distributor lower housing, being a disk-shaped mechanism, wherein a middle portion of the seed distributor lower housing is connected to an other end of the delivery tube;
• a seed distributor upper housing, fixed at an opening in an upper end of the seed distributor lower housing in a snapping manner, wherein a closed accommodating cavity is formed between the seed distributor upper housing and the seed distributor lower housing, and N seed guide tubes are arranged in a circumferential direction, N being a positive integer equal to or greater than 2;
• N blades are rotatably mounted in the accommodating cavity;
• the blades are arranged in a vertical direction;
• a closed independent seed guide cavity is divided in the accommodating cavity by two adjacent blades;
• an upper end of each seed guide tube is connected with a corresponding seed guide cavity;
• a top of the seed distributor upper housing is divided into N fan-shaped areas in the circumferential direction;
• an upper end of each blade is connected to an edge of a corresponding fan-shaped area by means of an elastic piece;
• and a collision sensor is provided in each fan-shaped area;
• and
• a blade driving mechanism, for driving the elastic piece to rotate, so as to change an included angle between two adjacent elastic pieces.
