High-efficiency scrap metal crushing roller

Abstract

The invention relates to the technical field of crushers, and discloses a high-efficiency scrap metal crushing roller, which comprises a first crushing roller body, a second crushing roller body and a fixed tool bit, a sliding groove is formed in the position, located on the side edge of the fixed tool bit, of the interior of the second crushing roller body, and a containing cavity is formed in the position, located on the lower side of the sliding groove, of the interior of the second crushing roller body. By designing the sliding tool bit, the sliding groove, a connecting rod, an first air bag, a second air bag and an ejector rod, the fixed tool bit on the first crushing roller makes contact with the sliding tool bit on the second crushing roller, the sliding tool bit moves towards the interior of the sliding groove, and meanwhile the connecting rod and the push plate are driven to extrude the first air bag; air in the first air bag enters the second air bag through the air hole, the ejector rod is driven by expansion of the second air bag to move upwards along the through groove to extend out of the surface of the fixed tool bit, waste metal sheets or metal blocks attached to the fixed tool bit are ejected down, and the waste metal sheets or the metal blocks are crushed through the sliding tool bit and the fixed tool bit, and the condition that waste metal sheets or metal blocks are attached to the fixed cutter bit, so that the equipment efficiency is low can be avoided.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a high-efficiency scrap metal crushing roller. Background technique [0002] With the introduction of ecological environmental protection, in order to reduce the exploitation of natural mineral resources, people gradually focus on the recycling and reuse of scrap metal resources, especially at the moment when natural mineral resources are extremely depleted and increasingly scarce, scrap metal Resources play a dominant role in the world economy and sustainable development strategy, and the recycling of scrap metal has the advantages of high yield, stable chemical composition, short smelting cycle, and less air pollution. [0003] However, in order to facilitate the recasting of scrap metal in the later stage, it is often necessary to crush the scrap metal after recycling. The scrap metal is crushed by a roller crusher, but the roller crusher mainly uses the relative rotation bet...

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing roller pulverizers proposed in the background technology, the present invention provides a high-efficiency scrap metal crushing roller, which can prevent scrap metal sheets from adhering to the fixed cutter head, and avoid crushing after crushing. The advantage of the excessive volume of scrap metal sheets solves the technical problems raised in the above-mentioned background technology
