Machine for working ridges, spreading mulch film and sowing wheat seeds

The utility model relates to a machine for working ridges, spreading mulch film and sowing wheat seeds. The utility model can complete the ridging, the film spreading, the sowing, and the pressing simultaneously, and can realize the sowing for the odd-numbered line of the side of the film. The utility model is characterized in that the upper side of the seed discharging wheels (16a) of a seeding apparatus (15a) is fixedly connected with a driven jaw clutch (19) which can be rotated freely, and the seed discharging wheels (16a) are arranged at both side of the bottom part of a seed box. The upper side of a feed shaft (17) is provided with two driving jaw clutch bodies (20) which can be rotated freely and can be shifted by a clutch operating mechanism which is fixedly connected to the upper side of a seedling quantity adjusting shifting block (24) to slide in an axial way. A colter (12a) which is arranged at one side of the film is composed of a vertical section and a slope section. The utility model can realize the odd-numbered line seeding at the side of the film, and the earth covering of the side of the film can not be scraped by the colter, which ensures the quality of the film spreading.
