Crawler-type wind prevention and sand fixation device

The invention relates to the field of wind prevention and sand fixation mechanical engineering, and discloses a crawler-type wind prevention and sand fixation device which comprises a moving device, and a ditching mechanism, a sand blocking mechanism, a forage feeding mechanism, a forage conveying mechanism and a forage pressing mechanism which are connected with the moving device. The device can conduct ditching, groove protection, storage and conveying of forage, pressing of straw mats, laying of the straw mats and pressing of the straw mats into the grooves at the same time, the laying efficiency of the straw checks is greatly improved, a series of work of straw checks desertification control can be systematically completed, the desertification control efficiency is effectively improved, in addition, a crawler-type driving device is adopted, and the labor intensity of workers is reduced. The crawler-type wheels increase the contact area and the grasping force between the vehicle and the ground, ensure the
