[0032] The overall operation process of the present invention is as follows: Place the integrated machine on the land to be sown and covered with film, place peanut seeds in the seed box, adjust the position of the film roll, activate the power traction device, and simultaneously turn on the sowing motor in the sowing device to start sowing. When the rotating disc moves the sowing barrel upward, the second bearing flange contacts the seed opening cover, opening it and allowing the seeds to fall into the sowing barrel. When the sowing barrel is lowered into the ground by the disc's rotation, its forward and upward movement opens the sowing cover, allowing the seeds to fall into the pit. Due to the action of the spring, when the seed bucket falls into the pit, the seed opening cover automatically seals the seed opening, completing the seeding process. As the seed bucket moves forward, the cover plate gathers the soil in the middle part, covers the seeds with soil, and flattens the ground. The soil pressing wheel then flattens the soil to facilitate the subsequent film covering process. After sowing is completed and the sown land has been pressed, the land is sprayed with pesticides or nutrient solution through the spraying device in the middle part of the all-in-one machine. The soil crushing knives are located on both sides of the front of the all-in-one machine. The soil crushing knives rotate to break up the soil blocks to be covered with film, so that the excavation device can transport more soil blocks to the top of the film. The rotation of the excavation motor drives the excavation knives on the conveyor belt to dig the soil. The excavation driven wheel excavates and transports the soil in the form of a waterwheel. The excavation driven wheel transfers the soil to the soil transfer box. Due to gravity, the soil flows along the soil transfer box to the top of the film at the rear. The film pressing wheel presses the film to facilitate soil covering. The film pressing wheel is designed with a pneumatic rod, which can better press the ground film. The soil blocks finally fall on the pressed ground film, completing the entire sowing, spraying and covering process.
