Description

Towed grass square laying machine

Technical Field

The utility model relates to a towed grass book square laying machine belongs to the agricultural machine class, especially relates to desert, half desert and desert area prevent wind sand fixation mechanized device.

Background

Grass grid sand fixation is a special artificial sand fixation mode in desert areas. The specific implementation mode is that a bundle of waste wheat straws is paved on sand in a square grid shape, then a spade is used for rolling the bundle into the sand, 1/3 or half of the remaining wheat straws naturally stand on the four sides, and then the sand in the center of the square grid is pulled to the roots of the wheat straws on the four sides, so that the wheat straws firmly stand on the sand. On the arranged grass square sand barrier, when airflow or wind sand flows through the sand barrier, vortex is generated and the phenomenon of sand accumulation is accompanied. After sufficient erosion and accumulation, a smooth concave curved surface (depression surface with balanced erosion and accumulation) is formed finally, the sand barriers in the square sand barrier sand area are collectively called as wind walls by people, and the grass square sand barrier is a wind blocking wall which is made of wheat straws, rice straws, reeds and other materials and is tied on a flowing sand dune into a square grid shape so as to weaken the erosion of wind power and is an important wind prevention and sand fixation mode. However, the manual work has high labor intensity and low efficiency, and the grass grid sand fixing machine is still low in efficiency due to the lack of material storage, automatic blanking and grass distributing mechanisms, so that the work speed is influenced by different degrees, the sand fixing cost cannot be reduced, and the application and popularization are difficult.
