Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a giant fungus grass seeding device. Background Art
[0002] Giant fungus grass is native to Africa and belongs to the genus Pennisetum in the family Poaceae, class Monocotyledons, phylum Angiosperms. Giant fungus grass has the characteristics of fast growth, large biomass, high crude protein and sugar content, strong resistance, wide adaptability and no risk of biological invasion. It has been widely cultivated and applied as a high-quality fungus grass, forage and ecological management material. At present, the main planting method of giant fungus grass is short-stem buried planting. Due to the harsh planting environment and high investment cost, giant fungus grass has not been planted on a large scale.
[0003] In the production process of giant grass, sowing is the most basic, most important and most labor-intensive production link. However, the current manual planting has low efficiency, high work intensity and high labor costs, so mechanized planting of giant grass is particularly important. For areas with less arable land and hilly slopes, the pre-cut seed short-stem buried planting method has a high survival rate and yield. This planting method is to arrange the pre-cut seedlings in an orderly and even manner in the seed ditch and cover them with about 5 cm of soil, followed by a series of planting processes such as compaction, film laying, and film pressing. Therefore, the key to the seeding device of the pre-cut seed short-stem buried planting machine is to ensure the stable and even fall of the seedlings. Since there are large individual differences among pre-cut giant fungus grass seedlings, with a length range of 120-150mm, a diameter range of 16-22mm, and the seedlings must retain 1-2 protruding young shoots, seedlings with unequal axial diameters and a certain curvature will cause the seed meter to miss seeds, get stuck seeds, and unevenly discharge seeds during planting, thus affecting the planting of giant fungus grass and seriously hindering the development of mechanized planting of pre-cut giant fungus grass and the promotion of large-scale planting.

The bottom of the housing 1 is opened so that the seed box 2 can form a sliding contact or a gap with the bottom of the lower seed box 3. The seed box 2 is bucket-shaped, and the lower end of the seed box 2 is inclined along the two side walls opposite to the sliding direction of the seed box 2.
