Detailed Description
To achieve the above objects and advantages, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in the figure, the utility model provides a seeding device of a rice seeding machine, which comprises a seed box 1 and a seed conveying pipe 2 communicated with the seed box, wherein a seed lifting disc 3 is rotatably arranged on one side inside the seed box 1, and the seed lifting disc 3 is connected with a power device of the rice seeding machine; a seed outlet 11 is also arranged on the side surface of the seed box 1, and the seed outlet 11 is positioned right above the rotating shaft 8 of the seed lifting disc 3; the tail end of the seed conveying pipe 2 is rotatably provided with a seed separating roller 6; the seed separating roller 6 is connected with the seed lifting disc 3 through a synchronous belt 4; the diameter of the seed distributing roller 6 is matched with the internal height of the seed conveying pipe 2, and the length of the seed distributing roller 6 is matched with the internal width of the seed conveying pipe 2; the seed separating roller 6 is provided with an arc-shaped seed lifting groove 61.
