Pressing feeding device for waste steel crusher

Abstract

The invention provides a pressing feeding device for a waste steel crusher. The pressing feeding device for the waste steel crusher comprises a frame, wherein the frame is placed at a feeding end of the crusher; a chute is placed on the upper part of the frame; a first rotating shaft of an upper pressing roller angular arm and a second rotating shaft of a pre-pressing roller lifting arm are placed on the upper part of the feeding end of the frame; the upper end of a pre-pressing roller oil cylinder is hinged to the middle of a pre-pressing roller lifting arm; the lower part of the pre-pressing roller oil cylinder is hinged to the middle of the frame; a pre-pressing roller is fixed on the lower part of the pre-pressing roller lifting arm; an upper pressing roller is fixed on the lower part of the upper pressing roller angular arm and the lower part of a pre-pressing roller; a lower pressing roller is fixed on the lower part of a discharging end of the frame; an upper pressing roller oil cylinder is placed on the lower part of the frame. The pressing feeding device for the waste steel crusher has the beneficial effects that the three pressing rollers are arranged on the pressing feeding device, thin shells with large boundary dimensions and light metal components can be crushed, the material processing range of the crusher is expanded, and the production efficiency of the crusher is improved. Therefore, the pressing feeding device for the waste steel crusher can pre-compress materials and limit the charging amount during charging of the materials.

Description

technical field [0001] The invention relates to the field of steel scrap crushing, in particular to a pressing material feeding device for a scrap steel crusher. Background technique [0002] At present, there are two main types of scrap steel processing equipment: one is packing and briquetting equipment, which is mainly used to process light and thin materials such as thin plates, construction scrap steel and metal cutting, so as to increase the stacking specific gravity and facilitate transportation. The second is the shearing equipment, which is mainly used to process heavy steel scrap and large components, which is convenient for entering the furnace. The above two types of scrap steel processing equipment all have the following deficiencies: the processing range is small, the debris in the scrap steel cannot be removed, and the quality of the scrap steel after processing is not good. It can only handle light and thin materials such as thin plates and metal cutting, as...
