Garbage screening machine with flail knife crushing function

Abstract

The invention discloses a garbage screening machine with a flail knife crushing function. The garbage screening machine comprises a rack body, a rotary roller screen and a crushing rotary shaft, wherein supporting wheels are arranged on a bottom side plate of the rack body; the rotary roller screen is placed above the supporting wheels; a working cavity is formed in the middle of the rotary roller screen; the crushing rotary shaft penetrates into the working cavity of the rotary roller screen; the rotation direction of the crushing rotary shaft is opposite to that of the rotary roller screen; a flail knife assembly is arranged on the crushing rotary shaft; crushing blades are arranged on the flail knife assembly; two ends of the crushing rotary shaft are respectively provided with a rotary shaft seat; the rotary shaft seats are assembled on the rack body. The garbage screening machine adopts a dual-action mode of opposite shaft screen rotation, is high in material crushing capacity and good in crushing effect, adopts a flail knife crushing mode and adopts a principle of inertial kinematics in physics; the rotary roller screen is independently adopted, and screen holes in the rotary roller screen can be prevented from being blocked; by arranging a water spraying pipe, double effects of cleaning the wall surface of the rotary roller screen and cleaning materials are achieved; the viscosity of the materials is reduced, and the materials are convenient to crush.

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.
