Description

Technical Field

[0001] The patent of the present invention relates to the technical field of agricultural machinery, and in particular to an integrated device for laying and rolling up a cold-proof blanket for grapes over the winter, which is pulled by a tractor. Background Art

[0002] China has a long history of grape cultivation, and its grape planting area and total output are among the highest in the world, occupying an important position among many grape producing countries in the world. China's grape cultivation is mainly concentrated in the north, where the winter is cold, dry and windy, which can easily cause frost damage and wind drying of grape vines. In order to ensure the safety of the grape vines over the winter, they need to be covered with cold-proof blankets in winter and rolled up in spring. Compared with the traditional buried cold-proof mode, the cold-proof blanket mode is easier to lay and roll up, causes less damage to grape vines, and can increase the temperature and humidity of the surface soil, so it is gradually being promoted. In recent years, some areas in Hebei, Xinjiang, Gansu and other places have gradually replaced the traditional buried cold-proof mode with the cold-proof blanket mode.

[0003] Winter blankets are laid on the trellises tied with grape vines. When they are rolled up manually, they must be dragged between the rows and rolled up manually. Since the blankets are heavy, they are slow to roll up manually and require a lot of manpower. Currently, there are no agricultural machines on the market for rolling up and laying out blankets.

[0004] In view of the current mechanization problem of laying and rolling up cold-proof blankets, the patent of this invention designs an integrated device for laying and rolling up cold-proof blankets for grapes overwintering, which is pulled by a tractor.
