Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tools, in particular to a grain planting and sowing device. Background Art

[0002] Cereals encompass a broad range of crops, including rice, wheat, millet, soybeans, and other grains. These crops, primarily consisting of seeds and fruits, are traditional staple foods for many Asian peoples. During the cereal planting process, seed spreading equipment is required.

[0003] Patent document CN212344473U discloses a grain planting and sowing device. A cover is mounted at the bottom end of a discharge pipe via a telescopic mechanism. A first magnetic portion is fixedly mounted on the lower surface of the cover. A side panel is fixedly mounted at each end of a first crossbar. Mounting plates are fixedly mounted on the outer ends of each side panel. A connecting mechanism is fixedly mounted between the two side panels. A cover is fixedly mounted on the connecting mechanism, and the cover is corresponding to a number of discharge pipes. A rotating shaft is rotatably mounted within the cover. A servo motor corresponding to the rotating shaft is fixedly mounted on the outer wall of the cover. The corresponding end of the rotating shaft passes through the cover and is fixedly connected to the output shaft of the servo motor. Connecting posts are fixedly mounted along the length of the rotating shaft, one corresponding to each first magnetic portion. A second magnetic portion is fixedly mounted on the end of each connecting post. This utility model has the advantage of allowing precise control of seed sowing intervals.

[0004] However, the existing seed spreading devices for grain planting are divided into land sowing and aerial sowing. Most of the aerial seed sowing devices are fixed on drones, and the seeds are thrown out by the seed spreading device to achieve a sowing effect over a large range. However, during the sowing process, the seeds themselves are relatively rough and have great friction with each other. The seed spreading device cannot play a dredging role, and when the seeds are loaded into the seed spreading device, they are easily squeezed and blocked in the feed port, thereby affecting the sowing efficiency. For this reason, we propose a grain planting seed spreading device. Utility Model Content
