Embodiment Construction

[0008] Refer to the accompanying drawings as follows: the vibrating screen includes a power part, a skeleton part of the screen body, a screen bar and a suspension part. Power part is made up of excitation motor 21 and excitation motor frame. The excitation motor frame is made of a support 19 and a beam welded by channel steel. Two supports 19 are welded respectively on the two side beams 22 of the upper screen frame, the crossbeam transverse bolts are fixed on the two supports 19, and the excitation motor 21 is bolted on the excitation motor crossbeam. The skeleton of the screen body is composed of front and rear end beams, side beams and connecting columns. The end beams 9, 11, 16, 18 are made of two channel steel buckle welds, and the side beams 12, 22 are respectively welded to the two ends of the end beams to form a rectangular screen frame. The manufacturing process of the upper and lower screen frames is the same, and four pairs of connecting columns 10, 13, 14, 17 ar...

Abstract

The invention relates to a vibrating screen and belongs to raw coal screening equipment. The vibrating screen consists of a power part, a screen body framework part, screening bars and a suspension part, and is characterized in that: a bracket is fixedly welded on two side beams of an upper screen frame; a transverse bolt of a crossbeam is fixed on the bracket; a vibration motor is fixed on the crossbeam; the side beams are respectively welded at two ends of an end beam to be respectively welded among a front end beam, the side beams and a rear end beam on upper and lower screen frames through four pairs of connecting posts; and the long annular screening bars are suspended on screening bar posts and screening bar hooks of the upper and lower screen frames. The vibrating screen has low amplitude and low noise, the requirement on screen intensity is low, transverse screening bars are absent, and the screen surface is not blocked.

Description

technical field [0001] The invention relates to a vibrating screen, more specifically a raw coal screening equipment. Background technique [0002] At present, due to the continuous improvement of coal mining mechanization in coal mines, the water content of the selected raw coal increases, so that the viscosity of the coal increases, and the sliding speed of the coal on the sieve bottom mesh slows down during screening. It is easy to stick to the sieve bottom mesh and is not easy to clean. Most of the vibrating screens on the market use sieve sheets and steel wire woven mesh, and there are horizontal sieve bars, which increase the resistance of the raw coal to slide down, and the small opening ratio reduces the raw coal processing capacity and is easy to block the bottom mesh of the screen. Contents of the invention [0003] The present invention proposes a semi-enclosed frame-type light-duty fine-grained vibrating screen to solve the existing problems in the prior art, s...
