Non-ridge combined tilling and seeding machine achieving equal-depth soil covering for wheat

The invention belongs to the technical field of tilling and seeding machines and discloses a non-ridge combined tilling and seeding machine achieving equal-depth soil covering for wheat. The non-ridge combined tilling and seeding machine achieving equal-depth soil covering for wheat is mainly and technically characterized by comprising a machine frame, wherein a fertilizer box with a fertilizer tube and a seed box with a seed box are arranged on the machine frame, the lower end of the fertilizer tube is inserted into a fertilizer tube fixing tube on the machine frame, a rotary tillage device and a land roller are arranged below the machine frame, a seed equalization device is arranged on the machine frame, a seed delivery tube is arranged at the upper portion of the seed equalization device, the lower end of the seed tube is inserted into the seed delivery tube at the upper portion of the seed equalization device, a soil throwing roll is arranged between the rotary tillage device and the seed delivery tube, arc-shaped soil throwing sheets are evenly arranged on the outer wall of the soil throwing roll, the rotary tillage device rotates anticlockwise, the soil throwing roll rotates clockwise, the seed equalization device is arranged at the lower end of the seed delivery tube, the top of the seed equalization device also serves as a soil covering plate matched with the soil throwing roll, and a first-level seed equalization plate, a second-level seed equalization plate and a third-level seed equalization plate are arranged in the seed equalization device in a staggered mode. According to the non-ridge combined tilling and seeding machine achieving equal-depth soil covering for wheat, seeds are evenly scattered to the ground, non-ridge planting is achieved, the soil covering plate makes seeds be covered with soil with the same depth, and emergence of orderly seedlings is guaranteed.
