Longitudinal and transverse two-way crusher

Abstract

The invention discloses a longitudinal and transverse two-way crusher. A feed hopper is arranged at the top of a machine body; a transverse crushing mechanism is arranged below the feed hopper, and comprises a pair of crushing rollers; one ends of the crushing roller pair are engaged through gears; a lower port of the feed hopper is aligned to the middle of the crushing roller pair; a longitudinal crushing mechanism is arranged below the transverse crushing mechanism; a movable jaw plate and a fixed jaw plate are vertically arranged, and jaw teeth are also vertical; a gap between the movable jaw plate and the fixed jaw plate is aligned to a gap of the crushing roller pair; the upper part of the movable jaw plate is rotationally fixed on the machine body through a bearing; the back surface of the lower part of the movable jaw plate is connected with a first push rod by a hinge; the other end of the first push rod is connected with a second push rod and a third push rod by hinges; the other end of the second push rod is rotationally fixed on the machine body through a rotating shaft; an eccentric shaft is arranged above the second push rod; two ends of the eccentric shaft are rotationally fixed on the machine body; the other end of the third push rod is fixed on the eccentric shaft; and a discharge port is formed below the movable jaw plate and the fixed jaw plate. The longitudinal and transverse two-way crusher is reasonable and reliable in structure, and realizes automatic crushing of a nodulizing agent.

Description

[0001] Technical field: [0002] The invention relates to the technical field of crushers, in particular to a vertical and horizontal bidirectional crusher for crushing cast plate-shaped nodularizers. [0003] Background technique: [0004] Ductile cast iron is spheroidal graphite obtained through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, so as to obtain higher strength than carbon steel. The nodulizer plays a vital role in the smelting of nodular cast iron. The production of nodulizers at home and abroad mainly adopts cast iron ingot molds and cast iron ingot molds with covers. In this way, nodulizers are poured, and the condensation speed of nodulizers Slower, the temperature rises rapidly during the cycle of ingot molds, and defects such as cracks and pits are more likely to occur during production, resulting in short service life, frequent replacement of glands and l...

AI Technical Summary

Problems solved by technology

[0005] Regardless of whether it is a water-cooled cycle mold or a cast iron ingot mold, the poured nodulizer is usually in the form of a large plate with a thickness of 2 to 3.5 cm, which is broken into smaller pieces before packaging and shipping. The hardness is low and brittle, so the method of manual crushing is generally adopted, and the steel drill is used for hammering, which is inefficient and labor-intensive
