Multi-stage environmentally friendly crushing device for concrete waste

Abstract

The invention relates to the technical field of concrete recycling, and discloses a multi-stage environmentally friendly crushing device for concrete waste. The multi-stage environmentally friendly crushing device comprises a crushing box, wherein the upper surface of the crushing box is provided with a feed inlet on the left side, the top of the crushing box is provided with an electromagnet, theupper parts of the left and right side walls of the crushing box are provided with hydraulic cylinders, piston rods of the hydraulic cylinders are fixedly connected to extrusion plates, the middle parts of the left and right side walls of the crushing box are provided with second rotating seats that are rotatably connected to the upper parts of support plates, the middle parts of the lower surfaces of the support plates are rotatably connected to the piston rods of the cylinders, the lower ends of the cylinders are provided with first rotating seats that are rotatably connected to the lower part of the crushing box, the lower part of the left side wall of the crushing box is provided with a drive motor, and the output shaft of the drive motor is fixedly connected to a first bevel gear. The invention is suitable for a multi-stage environmentally-friendly crushing device for concrete waste. The extrusion plates are arranged on the upper part of the device to first crush large pieces ofconcrete and separate steel bars in the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete recycling, in particular to a multi-stage environment-friendly crushing device for concrete waste. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is composed of cementitious materials, granular aggregates (also known as aggregates), water, and if necessary, admixtures and admixtures prepared in a certain proportion, uniformly stirred, densely formed, cured and hardened. artificial stone. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete...

AI Technical Summary

Problems solved by technology

One side of the crushing block is welded with an upper shearing plate, and the lower shearing plate and the upper shearing plate are engaged with each other. When the crushing is crushed, the lower shearing plate and the upper shearing plate are engaged with each other, and the initially broken construction concrete solid waste, together with the internal The wrapped steel bar is cut to make the two crushing rollers crush the concrete block more thoroughly, avoiding the phenomenon of equipment damage caused by the steel bar winding inside the device, and improving the crushing efficiency. Although the device can cut the steel bar, it does not separate the steel bar from the Concrete separation, subsequent processing is still relatively difficult, so the device needs to be improved
