High-efficiency crushing device for construction waste recovery

Abstract

The invention discloses a high-efficiency crushing device for recycling construction waste, which includes a machine body, a first motor, a first connecting rod, a second connecting rod and a movable jaw plate are symmetrically arranged on the top of the body, and the first motor is driven to connect the first connecting rod. The other end of the first connecting rod is hinged with the second connecting rod, and the other end of the second connecting rod is hinged with a movable jaw plate. The bottom of the movable jaw plate is connected to the top of the body through a hinge. An inclined plate is fixed in the lower part of the body, a conveying device is arranged under the inclined plate, an iron removal device is arranged above the conveying device, an arc-shaped plate is fixed under the left end of the conveying device, and a secondary crushing device is arranged under the right end of the arc-shaped plate. The invention is provided with a first motor, a first connecting rod, a second connecting rod and a movable jaw plate, which can pre-shred the construction waste, and is provided with an iron removal device to remove metals such as steel bars and steel bars in the construction waste to avoid Damage the device and affect the service life of the device.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a high-efficiency crushing device for recycling construction waste. Background technique [0002] With the development of social economy, our country continues to deepen urbanization construction, coupled with the improvement of consumption level, there are more and more construction waste in cities, and most of the construction waste is arbitrarily landfilled and piled up by construction units without any treatment. It not only affects the environment, but also wastes renewable energy. At present, the construction waste crushing devices used by enterprises generally use crushing rollers directly for crushing, and construction waste often contains steel bars, steel bars and other metals, which are directly crushed by crushing rollers, which is easy to use The crushing roller is damaged, and the device is stuck, which seriously affects the service life of the device...

[0002] With the development of social economy, our country continues to deepen urbanization construction, coupled with the improvement of consumption level, there are more and more construction waste in cities, and most of the construction waste is arbitrarily landfilled and piled up by construction units without any treatment. It not only affects the environment, but also wastes renewable energy. At present, the construction waste crushing devices used by enterprises generally use crushing rollers directly for crushing, and construction waste often contains steel bars, steel bars and other metals, which are directly crushed by crushing rollers, which is easy to use The crushing roller is damaged, and the device is stuck, which seriously affects the service life of the device, and even safety accidents occur, which is insufficient; and due to the source of construction waste, some wood chips and plastic bags may be mixed in, and this type of material is not suitable It is conducive to the production and utilization of construction waste in the later stage, which will reduce the viscosity of the construction waste itself, which will reduce the quality. At the same time, it is difficult for this kind of material to be crushed well when it enters the crusher, which is not conducive to processing and production.
