Description

Grass tumbling device capable of shaking off grass and sweeping off grass

technical field

The invention relates to a forage tumbling device, more particularly to a forage tumbling device with an adjustable turning hook angle.

Background technique

In modern animal husbandry, it is usually necessary to plant a large amount of forage for livestock, and it is necessary to cut down a large amount of forage during the harvest season, expose it to the sun, and collect and store it after drying, so as to feed livestock in winter.

Because the forage of the pasture is usually planted with a high density, after the grass is cut down, the thickness of the forage layer formed by the forage is very thick, which is not convenient for sun exposure. Therefore, in order to make the forage evenly exposed to the sun, increase the drying speed, make the forage more resistant to storage, and improve the quality of the stored forage, it is necessary to repeatedly turn the forage layer for drying.

At present, the forage layer is mainly turned over by hand. The shortcoming of doing like this is obvious, and its tumbling speed is slow, and labor load is big, and the evenness of tumbling is limited.

There are also some mechanized tumbling methods at present, but because the thickness of the forage layer in the pasture will change, it is difficult for the turning machine to make adaptive changes for the forage layer of different thicknesses to properly turn the forage tumbling.
