Technical Field
[0001] This utility model relates to a vibrating screen, belonging to the field of solid material screening technology. Background Technology
[0002] Currently, a vibrating screen is a mechanical device that uses vibration to screen, classify, remove impurities, or filter materials. It is widely used in industries such as mining, metallurgy, chemical, building materials, food, and pharmaceuticals. The vibrating screen generates periodic vibrations through a motor-driven vibrator (or vibrating motor), causing the material on the screen surface to stratify and pass through the screen during throwing or horizontal motion.
[0003] However, existing vibrating screen structures are relatively rudimentary. For example, the patent application number 202121497204.2, entitled "A Vibrating Screen Device Provided with Excitation Force by a Vibrating Motor," includes: a screen box, a vibrating motor, a screen mesh, a spring seat, and a spring. The vibrating motor, which provides excitation force, is connected to the tail end of the screen box. The two outer walls of the screen box are connected via the spring seat, and a screen mesh is located at the bottom of the screen box. The screen box is an integrated component consisting of five parts: side panels, a bottom panel, a screen groove plate, a top screw, and a spring pressure seat. The screen mesh consists of a sieve and a screen pressure plate. The spring seat consists of a base and a protective sleeve. However, the disassembly of the screen mesh in this patent is cumbersome, making it inconvenient to clean and collect the separated debris. The generated excitation force is insufficient, resulting in poor debris separation. Utility Model Content
