Multi-tooth crushing type construction garbage pulverizing device

Abstract

The invention discloses a multi-tooth crushing type construction garbage pulverizing device, which comprises a crushing box. The top of the crushing box is fixedly provided with a cover plate; the topend of the cover plate is fixedly provided with a feeding hopper; the inside of the crushing box is fixedly connected with a horizontally arranged support plate; the support plate is fixedly connected with a fixed block; the upper end of the fixed block is fixedly connected with a fixed jaw; a movable block is arranged on one side of the fixed block; the top end of the movable block is fixedly connected with a movable jaw; first pulverizing teeth are arranged on the fixed jaw and the movable jaw; a driving mechanism is arranged on the side, away from the fixed jaw, of the movable jaw; a feeding mechanism is arranged between the fixed block and the movable block; a screening mechanism is arranged below the feeding mechanism. According to the multi-tooth crushing type construction garbage pulverizing device disclosed by the invention, the fixed jaw and the movable jaw can clamp and pulverize gravels; the screening mechanism can screen the pulverized gravels; furthermore, the gravels inrelatively large volumes are subjected to secondary pulverization through a residue pulverizing device, so as to perfect the pulverizing work and contribute to recycling construction gravels.

Description

technical field [0001] The invention relates to the field of recycling and processing of building materials, in particular to a multi-tooth crushing type construction waste crushing device. Background technique [0002] With the development of the economy and the progress of the society, people's living environment has undergone tremendous changes. Especially in recent years, the urbanization process has accelerated, the construction industry has become increasingly developed, and there are many demolition and reconstruction projects in various places. construction rubbish. [0003] The amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste, and the accumulated construction waste year by year will be a shocking figure. However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is piled in the open air or landfilled, which consumes a lot of con...

Problems solved by technology

However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of construction expenses such as land acquisition fees, garbage removal and transportation fees, and at the same time, during the process of clearing, transporting and stacking Problems such as the scattering of dust and flying dust and sand have caused serious environmental pollution.

[0004] Construction waste is not real waste, but "gold" that has been misplaced. Construction waste can be reused after being sorted, removed or crushed. However, the current recycling rate of construction waste is very low. The number of mechanical equipment for garbage crushing is small, and the cost of such mechanical equipment is high, the structure is complex, and it is inconvenient to use
