High-efficiency crushing machine

Abstract

The invention discloses a high-efficiency crushing machine. A crushing device is arranged on a rack; a crushing feeding hole and a crushing discharge hole are respectively formed in the upper part and the lower part of the crushing device; a rolling screen which can rotate relative to the rack and is of a cylindrical structure, and a rolling screen driving device for driving the rolling screen to rotate are arranged on the rack; the crushing discharge hole is positioned in the inner side of the rolling screen; crushed garbage falls on the continuously rotating rolling screen through the garbage discharge hole; when the fineness of the crushed garbage meets provided requirements, the garbage can be screened off from the rolling screen, the garbage which does not meet the fineness requirements rotates along with the rolling screen, falls into the crushing feeding hole when rotating to a highest point, and is further crushed. Therefore, the uniform fineness of the garbage screened off from the rolling screen is effectively ensured, the process requirements can be met, and garbage which does not meet the fineness requirements can be automatically crushed for the second time or multiple times, so that the labor operation cost can be lowered, and the crushing efficiency can be improved.

Description

【Technical field】 [0001] The invention relates to an environmental protection machine, in particular to a crusher. 【Background technique】 [0002] At present, the garbage crushers used in the market generally adopt a double-shaft structure, and the garbage is discharged after being crushed once by the crushing box. Since the crusher with this structure only crushes the garbage once, it is inevitable that some garbage will be discharged without being crushed, or it will be crushed. The thickness of the final material is not uniform and cannot reach the required fineness. For this reason, people usually crush the garbage materials that have been crushed once, which increases the cost of garbage crushing and increases the labor intensity of workers, which is time-consuming and laborious. , and is not conducive to environmental protection. [0003] The present invention studies and proposes aiming at the deficiencies in the prior art. [Content of the invention] [0004] The ...
