Working machine for laying mulch, dibbling and closing holes for crops

The utility model relates to a machine of mulching-film paving, dibbling and cave sealing for mulching-film crop which consists of a frame, a mulching-film paving mechanism, a dibble over mulching-film and a sealing cave and covering soil device. Its characteristics lie on that a cave sealing film paving device is set between the dibble over mulching-film and the sealing cave and covering soil device, the cave sealing film paving device contains a cave sealing film roller under-back which a pressing film roller is set. The cave sealing mulching-film roller is narrower than the mulching-film roller of the mulching-film paving mechanism. Compared to the current technology, after the utility model seals caves by cave sealing film after sowing, vapor will not escape, excellent effects for preservation of soil moisture will be obtained and germination rate of seeds will be ensured, meanwhile, the operation for opening seedling is simple, just to take off the film, so quick seedling opening can be realized to prevent from seedling burned phenomenon happened owing to untimely seedling opening, labor intensity of seedling opening after opening seedling can be reduced significantly.
