Description

Technical Field

[0001] This utility model belongs to the technical field of jaw crushers, specifically relating to a splash prevention device for the feed inlet of a jaw crusher. Background Technology

[0002] Jaw crushers, also known as jaw breakers or tiger's mouth crushers, consist of a crushing chamber formed by two jaw plates: a movable jaw and a fixed jaw. They mimic the jaw movements of an animal to crush materials. Widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries for crushing various ores and large materials. The maximum compressive strength of the material to be crushed is 320 MPa. While jaw crushers may vary in structure, their working principles are essentially similar, differing only in the trajectory of the movable jaw. In short, when the movable jaw plate reciprocates periodically around the suspension shaft relative to the fixed jaw plate, sometimes approaching and sometimes moving away, the ore between the two jaw plates is crushed by a combination of compression, splitting, and bending when the movable jaw plate approaches the fixed jaw plate. When the movable jaw plate moves away from the fixed jaw plate, the crushed ore is discharged through the crusher's discharge port under gravity.

[0003] Currently, when jaw crushers are crushing materials, the force generated by their crushing action causes debris to fly out, which can easily injure operators. Therefore, a splash prevention device is needed at the feed inlet of jaw crushers. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a splash prevention device for the feed inlet of a jaw crusher, which solves the problem that when materials are crushed, the force generated by the crushing causes debris to fly out, easily injuring operators.
