Rubbish screening machine with flail knife crushing function

Abstract

The invention discloses a rubbish screening machine with a flail knife crushing function. The rubbish screening machine comprises a machine frame body, a rotating roller screen and a crushing rotary shaft, wherein supporting wheels are arranged on a bottom side plate of the machine frame body, and the rotating roller screen is arranged above the supporting wheels; the middle of the rotating rollerscreen is a working cavity, the crushing rotary shaft is arranged in the working cavity of the rotating roller screen in a penetrating manner, and the rotating direction of a rotating shaft for crushing and the rotating direction of the rotating roller screen are opposite; and the rotating shaft is provided with a flail knife assembly, crushing blades are arranged on the flail knife assembly in amatched manner, rotating shaft bases are arranged at the two ends of the rotating shaft for crushing, and the rotating shaft bases are assembled on the machine frame body. A double-action mode of opposite rotation of a shaft screen is high in the material crushing capacity, and the flail knife crushing mode adopts the principle of inertia operation in physics, so that the crushing effect is good;the rotating roller screen is independently arranged, and screen holes in the rotating roller screen can be prevented from being blocked; a water spraying pipe is arranged, and has a double effects of cleaning a wall surface of the rotating roller screen and cleaning materials, so that the viscosity of the materials is reduced, and the crushing is facilitated.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a garbage screening machine equipped with a throwing knife crushing function. Background technique [0002] Garbage is commonly referred to as waste. When it comes to garbage, it is always considered to be a harmful substance. In fact, garbage is also divided into types, including garbage rich in organic substances. This type of garbage can be recycled as a resource; of course, it is waste. , resource recycling and sundries must be mixed together, how to effectively separate recycled materials, there are many existing technologies, such as the Chinese utility model patent "Roller for Disposal of Garbage" with patent number CN201020242385.X Screening machine" (announcement number is CN201799393U); a drum screening machine for processing garbage, including a base, supporting rollers, a drum, a driving device, a protective cover, the supporting rollers are arranged on the ...

AI Technical Summary

Problems solved by technology

The design adopts the drum screen mode. Conventional fine materials can be sorted through the drum screen, but there are some tough objects in the general materials. If they are not fully broken, such tough objects cannot be separated. Separated, and usually such tough objects are also organic substances, such a structural design will inevitably lead to the outflow or waste of recyclable resources, which does not conform to the principle of maximizing resource utilization, so there are still many defects in this design, and the technology has not yet been developed.
