Description

Technical Field

[0001] This utility model relates to the field of rock and soil crushing technology, specifically a rock and soil crushing device for rock and soil engineering mining. Background Technology

[0002] From an engineering and construction perspective, soil and rock are a collective term for any kind of rock and soil that make up the Earth's crust. Soil and rock can be further divided into five categories: hard (hard rock), medium hard (soft rock), weakly connected, loose and unconnected, and those with special composition, structure, state and properties.

[0003] A search revealed that patent application number 202421004839.8 discloses a crushing device for geotechnical engineering with screening function. This utility model provides such a crushing device for geotechnical engineering, comprising a frame, a coarse block frame, a fine crushing frame, a material frame, a motor, and a crushing wheel. The coarse block frame and the fine crushing frame are installed on the left side of the frame, and the material frame is installed on the upper part of the frame. A symmetrically arranged motor is installed on the upper part of the frame, and a crushing wheel for crushing geotechnical materials is connected to the output shaft of the motor via a coupling. The crushing wheel is rotatably connected to the material frame. The device also includes slide rails and a screen. Slide rails are arranged horizontally on the lower part of the frame, and a screen for screening geotechnical materials is slidably connected between two of the slide rails. By setting the screen to screen the crushed geotechnical materials, the device achieves the effect of automatically screening the size of the geotechnical materials.

[0004] The aforementioned application documents demonstrate that the crushing of rock and soil can be achieved through the configuration of various components. However, the crushing efficiency of a single crushing roller is low, and the structure of the bottom screening component is limited, making it difficult to flexibly disassemble. Consequently, the crushing efficiency and subsequent screening effect are limited.

[0005] Therefore, we propose a soil and rock crushing device for geotechnical engineering mining. Utility Model Content
