Along with the continuous development of cities, the population of towns is continuously increased, and the generated household garbage is also continuously increased. The random stacking of household garbage also becomes an increasingly serious social problem. The existing household garbage is mostly accumulated in an open or semi-open type collection mode such as an open garbage platform, a garbage can and the like, and then is transported to a garbage landfill site for landfill by a semi-open type vehicle. These places are easily affected by weather and are the breeding places of mosquitoes and mice. The scattered garbage is bulky, large in size, heavy in cleaning task, large in input manpower, material resources and financial resources and extremely low in efficiency, and meanwhile, precious land resources of a garbage landfill are wasted;
