Problems solved by technology

When the integral vibrating vibrating screen is working, the screen box and the screen surface vibrate together. The screen box has a huge structure, high energy consumption, and a large vibration force on the foundation. In addition, due to the high rigidity of the screen box, it also hinders the enlargement of the vibrating screen; When the screen vibrating vibrating screen is working, the screen is fixed on the screen box, usually by tapping or pulling the screen to vibrate part of the screen, resulting in low utilization of the screen and uneven vibration, and rapid wear of the screen

Abstract

The invention discloses a vibrating screen with a vibrating screen surface and static screen box and aims to provide a vibrating screen which is low in energy consumption and foundation vibrating force and can be made in large size easily. The vibrating screen comprises a machine frame, a screen surface, a vibrating device and a transmission mechanism, wherein the transmission mechanism comprises a transmission rod, vibrating rods, rotating shafts, rotating shaft seats and a vibrating arm, wherein the vibrating device is connected with the transmission rods; the transmission rod is hinged with the vibrating rod, the vibrating rod is sleeved on the ends of the rotating shafts; the rotating shafts are arranged in the rotating shaft seats; at least two rotating shaft seats are arranged on each rotating shaft; the vibrating arms are arranged on the rotating shafts; the rotating shaft seats and the vibrating device are arranged on the machine frame; and the screen surface is fastened on the vibrating arms by bolts. The vibrating screen can be widely used in energy resource, metallurgical, ceramic, building material, chemical industries and other industries and mainly used for material grading and dehydration.

Description

technical field [0001] The invention relates to a vibrating separation device, in particular to a vibrating screen whose screen surface vibrates but the screen box does not vibrate. Background technique [0002] At present, vibrating screens are widely used in energy, metallurgy, ceramics, building materials, chemical industries and other industries. They are mainly used for material classification and dehydration. Vibrating screens mainly have two forms: integral vibration type and screen vibration type. When the integral vibrating vibrating screen is working, the screen box and the screen surface vibrate together. The screen box has a huge structure, high energy consumption, and a large vibration force on the foundation. In addition, due to the high rigidity of the screen box, it also hinders the enlargement of the vibrating screen; When the screen vibrating vibrating screen is working, the screen is fixed on the screen box. Generally, part of the screen is vibrated by tap...
