Detailed Description

The principles and features of the present invention will be described with reference to the accompanying fig. 1 to 4, wherein the examples are provided only for explaining the present invention and are not intended to limit the scope of the present invention.

A seed discharging assembly of a seeder comprises a feed box 1, a first distributing wheel 4, a discharging box 5 and a discharging pipe 7. Workbin 1 is by iron plate welded fastening, workbin 1 is formed with first cavity 2 and second cavity 3 that communicate each other, just first cavity 2 sets up in the top of second cavity 3, the top of first cavity 2 covers to establish and is connected with case lid 15. The first distributing wheel 4 is rotatably connected between the first chamber 2 and the second chamber 3, the first chamber 2 and the second chamber 3 are separated from each other through the first distributing wheel 4, and distributing grooves are formed in the first distributing wheel 4 in a circumferential array mode. The rotation of the first distribution wheel 4 enables the seeds placed in the first chamber 2 to be discharged progressively into the second chamber 3, thus preventing the hardening of the stack due to the excess of seeds. The discharging box 5 is communicated with the bottom of the second cavity 3, a second distributing wheel 6 is connected in the discharging box 5 in a rotating mode, and distributing grooves are formed in the second distributing wheel 6 in a circumferential array mode. One end of the discharging pipe 7 is communicated with the discharging box 5, and the other end of the discharging pipe extends to the ground. The rotation of the second distribution wheel 6 enables the seeds to be discharged from the second chamber 3 into the discharge pipe 7 and finally through the discharge pipe 7 into the groove in the ground.
