Description

Technical Field

[0001] The utility model relates to the technical field of forage grass planting, in particular to a grass sowing device for cattle and sheep breeding. Background Art

[0002] Forage grass is the basis for the development of livestock and poultry production, especially the production of herbivorous livestock. Forage grass not only contains various nutrients necessary for livestock, but also contains crude fiber that is particularly important for maintaining the health of ruminant livestock, which is irreplaceable by grain and other feeds. The planting of forage grass often brings certain high returns and high profits. Many forage grasses are promoted to be innovative, and this industry is also developing continuously. At present, forage grass alfalfa is often planted using a multifunctional forage grass alfalfa precision planter with a model of HR-BZJ. As is known to all, a distributing roller is rotatably installed at the discharge port below the seeding box of the multifunctional forage grass alfalfa precision planter (no-tillage planter), and the distributing roller can close and block the discharge port below the seeding box. A plurality of distributing grooves are evenly arranged on the periphery of the distributing roller. The distributing roller is coaxially fixedly installed inside and fixedly connected with the main shaft of the multifunctional forage grass alfalfa precision planter. When the multifunctional forage grass alfalfa precision planter is sowing, the main shaft is in a rotating state, and the distributing roller is driven by the main shaft to rotate synchronously, so that the forage grass seeds in the distributing groove above the distributing roller are turned down and discharged.

[0003] However, the inner size of the discharge port of the seeding box decreases gradually from top to bottom. If the forage seeds change too quickly, it is easy for the forage seeds in the seeding box to mesh with each other to reach a force balance state to form a material arch, or to form a bridge due to compaction due to pressure, or to form a material arch due to the adhesion between the forage seeds and the inner wall of the seeding box enhanced by water, moisture absorption or static electricity; that is, a bridge may form in the seeding box, making it difficult to feed the grass.
