[0002] Solid waste refers to solid and semi-solid waste materials generated by human beings in production, consumption, life and other activities (the definition abroad is more extensive, and waste generated by animal activities also belongs to this category). In layman's terms, it is "garbage". It mainly includes solid particles, garbage, slag, sludge, discarded products, broken utensils, defective products, animal carcasses, spoiled food, human and animal feces, etc. Some countries also classify high-concentration liquids such as waste acid, waste alkali, waste oil, and waste organic solvents as solid waste. Solid or semi-solid materials that have no "utilization value" and are abandoned.

[0003] In the prior art, the patent with announcement number CN215277541U discloses an environmentally friendly solid waste treatment equipment, including a box body, a protective cover and a guide hopper, the top surface of the box body is inlaid with a protective cover, the left wall of the protective cover is installed with a guide hopper, the top of the two side walls of the inner cavity of the box body are welded with baffles, a crushing roller is provided on one side of the bottom of the baffle, a motor is provided at the bottom of the box body surface, a first dust suction nozzle is inlaid with the top surface of the protective cover, a grille cover is installed on the top surface of the inner cavity of the protective cover, and a dust collector is installed in the middle of the right side wall of the box body. The utility model can provide adsorption power to the first dust suction nozzle and the second dust suction nozzle respectively through the dust collector, so as to adsorb the dust generated when the material is broken and exported from the box body, so as to reduce the pollution of the dust equipment to the environment, and the mobile mechanism can not only make the equipment have a certain shock absorption effect, but also facilitate the staff to carry the waste treatment equipment;

[0004] However, this patent also has the following disadvantages:

[0005] The crushing rollers in this structure cannot be adjusted. If the gap between the crushing rollers is not adjusted when crushing larger or harder waste, the crushing rollers will be easily damaged.

[0006] This patent only uses two crushing rollers to perform crushing operations, and crushing by crushing rollers alone is prone to incomplete crushing;
