A construction waste crushing device based on the principle of crank rocker

Abstract

The invention relates to the technical field of construction waste, and discloses a construction waste crushing device based on the principle of a crank rocker, including a pre-crushing chamber, the outside of the pre-crushing chamber is fixedly connected with a feeding port, and the inside of the pre-crushing chamber A crank rocker is movably connected, and a pre-crushing motor is fixedly connected to the outside of the crank rocker, and a connecting rod is movably connected to the outside of the crank rocker, and an impact rod is hingedly connected to the outside of the connecting rod, and the impact rod The bottom of the hammer is fixedly connected with an impact hammer. Through the combined use of the pre-crushing motor and the impact hammer, the impact hammer is used to impact and crush the construction waste to achieve the effect of pre-crushing the construction waste. The bulk construction waste is processed into small fragments, thereby ensuring the use effect of the subsequent crushing rollers, and preventing large blocks of construction waste from damaging the crushing rollers, thereby increasing the service life of the crushing device.

Description

technical field [0001] The invention relates to the technical field of construction waste, in particular to a construction waste crushing and processing device based on the crank rocker principle. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. As people pay more attention to the environment and the recycling of resources, they also pay more and more attention to the recycling of construction waste. Construction waste can use waste construction concrete and waste bricks to produce coarse and fine aggregates, which can be used to produce concrete with corresponding strength levels. , Mortar or preparation of building materials such as blocks, wall panels, floor tiles and other products. [0003] In the recycling process of construction waste, it is nec...

AI Technical Summary

Problems solved by technology

[0003] In the recycling process of construction waste, it is necessary to crush the construction waste. However, the existing construction waste crushing devices often only use crushing rollers for one crushing process, and it is difficult to completely crush the construction waste. When crushing the block, it is likely to cause damage to the crushing roller and reduce the service life of the equipment; the crushed construction waste contains a large amount of dust, which will pollute the air; the feeding speed cannot be effectively controlled during crushing, and the If the material speed is too slow, the crushing device will not be fully used and work efficiency will be reduced. If the feeding speed is too fast, the crushing will be incomplete and the crushing effect will be poor; after crushing, the metal doped in the fine building fragments cannot be processed Separation not only affects the quality of fine building debris recycling processing, but also causes waste of metal materials
