The utility model relates to a soil scraping device for a wheel of an unearthing vehicle. The soil scraping device comprises a soil scraping structure, wherein the width of the soil scraping structureis matched with that of the wheel; a grid for scraping muck of the wheel is formed at the top of the soil scraping structure; and the storage structure is detachably arranged at the bottom of the grid of the soil scraping structure and is used for accommodating muck. The soil scraping device for the wheels of the unearthing vehicle is placed at the bottoms of the wheels by adopting a soil scraping structure; when the wheels roll at the top of the soil scraping structure, soil is scraped; the grid of the soil scraping structure moves relative to the wheels; if residue soil is adhered to the wheels; residue soil of the wheels is peeled off through the unsmooth grids and falls into the storage structure, the residue soil peeled off from the wheels is collected, the storage structure is takenout to dump the residue soil in a unified mode after the wheels are full of the residue soil, the ground is prevented from being polluted, the residue soil is conveniently cleaned up, and the problems that in the prior art, manual cleaning is not in place, labor is wasted, and time efficiency is low are solved.
