Description

Technical Field

[0001] The invention relates to the technical field of sand-fixing grass burial technology, in particular to a self-propelled sand-fixing grass burial device. Background Art

[0002] In desert areas, in order to prevent wind and fix sand, materials such as wheat straw, rice straw, and reeds are usually used to fill the mobile sand dunes into a grid-shaped windbreak wall to weaken wind erosion. At present, there are some grass burying machines on the market, mainly including a storage tank box, which is used to store grass bales or loose grass stalks. A toothed roller is rotated at the bottom outlet of the storage tank box, and the grass in the grass storage box is pushed back and spread on the sand by the toothed roller, and then pressed into the sand by a grass pressing wheel to complete the grass burying. This type of equipment has the following problems in actual use: 1. The bales or straws in the straw storage box fall on the toothed roller by their own gravity. Therefore, when the bale is light, the bale will idle, the toothed roller will not be able to separate the straw from the bale, or the straw will be arched, making it difficult to ensure the amount of grass pulled out by the toothed roller, affecting the effect of burying grass and fixing sand; 2. The machine needs to be stopped during the grass burying process, and the bales or straws need to be manually moved regularly to avoid the above phenomenon and ensure the grass burying effect, but the shutdown processing efficiency is low, and there will be the phenomenon of not stopping the machine and manually moving, which poses a great safety hazard; 3. This type of equipment is mainly suitable for round bales. When the toothed roller moves the straw, the round bale will rotate to achieve continuous unloading of the circumference of the bale, but it is not suitable for square bales. The faces of the square bale are flat and have edges and corners. Therefore, when the toothed roller moves the square bale, the square bale is not easy to rotate and needs to be adjusted continuously by humans, resulting in uneven grass laying, which seriously affects the effect and efficiency of burying grass.
