This utility model provides a potato film-planting machine. It features a suspension assembly for connection to a tractor; a quantitative seed dispensing mechanism and a hole-planting mechanism for quantitatively dispensing potato seeds into planting holes; and a soil-shoveling assembly for excavating soil from furrows and transporting it to a soil-covering assembly. The soil then falls over the planting holes, covering the potatoes, thus enabling early film-planting of potatoes. This method achieves film breaking, quantitative seed dispensing, and fixed-hole soil covering, reducing manual labor, increasing planting speed, minimizing soil moisture loss, and improving potato germination rate.

This invention discloses an unmanned tracked robot for agricultural sowing, relating to the field of agricultural machinery technology. It includes an unmanned tracked sowing vehicle with a trapezoidal block fixedly connected to its top. A fixed horizontal plate is fixedly connected to the side wall of the trapezoidal block, and a centrifugal sowing component is mounted on the top of the fixed horizontal plate. The centrifugal sowing component includes a stepper motor fixedly connected to the side wall of the trapezoidal block. The centrifugal sowing component utilizes centrifugal force to throw seeds from the sowing device, causing the seeds to disperse evenly within a certain range. This avoids excessive concentration or uneven distribution of seeds, ensuring uniform seed distribution in the field and promoting uniform crop growth. The centrifugal sowing device can perform sowing operations at a high speed, significantly improving sowing speed compared to traditional manual sowing or some low-speed sowing methods. It can complete large-area sowing tasks in a short time, making it particularly suitable for large-scale agricultural production and effectively shortening the sowing cycle.

This utility model discloses a vacuum adsorption type seedling tray seeder, including a frame, a pressing roller, a sowing roller, and a seed bin. The pressing roller is equipped with pressing teeth, and the sowing roller is hollow under negative pressure. The sowing roller has several seed adsorption nozzles, and its shaft is a hollow rotating shaft. One end of the hollow rotating shaft connecting to the transmission component is closed, and the other end is connected to a vacuum pump. An opening is provided in the middle of the hollow rotating shaft. The seed bin is located behind the sowing roller, and a seed bin baffle is located at the bottom of the seed bin. A soft seed-dispensing baffle is provided at the front end of the seed bin baffle. This utility model device can easily adsorb any point of irregularly shaped crop seeds, with a seed adsorption rate approaching 100%. Seeds will not fall during movement, significantly improving sowing quality. It also retains the roller structure, resulting in fast sowing speed, simple structure, and low cost. A substrate cleaning device is also installed at the front of the frame to clean the substrate.
