Efficient crushing device with double-speed rebound plate

Abstract

The invention discloses an efficient crushing device with a double-speed rebound plate, and relates to the technical field of solid-waste crushing devices. The crushing device comprises a crushing device housing, a charge hole, a discharge hole, a primary crushing mechanism and a secondary crushing mechanism, wherein a square bounding plate, a square supporting steel plate and a telescopic air cylinder for driving the square supporting steel plate to move back and forth are sequentially connected in the bottom of the crushing device housing from top to bottom; the bottom of the telescopic air cylinder is fixedly arranged in the bottom of the crushing device housing; the lower end of the square bounding plate is equipped with buckles I; buckles II which correspond to the buckles I are arranged on the square supporting steel plate; a spring pulling hook is connected between the buckles I and the corresponding buckles II; the primary crushing mechanism comprises a rotary shaft I, as well as spiral crushing tools, cylindrical-tooth tools and a motor I which are alternatively and uniformly distributed on the rotary shaft I according to the periphery; and the secondary crushing mechanism comprises a rotary shaft II as well as crushing tools and a motor II which are uniformly distributed on the rotary shaft II according to the periphery. By combining a rebound device, crushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of solid waste shredding devices, and more specifically relates to a high-efficiency shredding device with a double-speed rebound plate. Background technique [0002] For the treatment of solid waste, large-scale crushing devices are usually used to crush the waste. The crushing of solid waste is the process of changing solid waste from large to small. External force is used to overcome the cohesive force between the solid waste material points to split large solid waste into small pieces. the process of. [0003] Existing solid waste shredders are usually equipped with one or more rotating shafts driven by motors inside the shredding device, and multiple groups of shredding knives with different structures and functions are arranged on the shafts. When the solid waste falls freely due to its own gravitational potential energy, it is in constant contact with the crushing tool. The crushing tool rotates rapi...
