Problems solved by technology

However, it is inconvenient to replace the belt, and the processing technology of the transmission shaft is complicated and the cost is high
The screen frame is hinged on the frame, and the deflection movement is easy to occur due to the assembly error of the frame, which affects the running stability of the relaxation screen
[0009] The patent number is 201220585644.8, which is named "a relaxation screen with guide rails". The screen box is arranged in the form of guide rails and runs smoothly. inertial force of motion

Abstract

The invention discloses a distributed driven type rocking sieve comprising a base, a motor, a driving shaft, a first crank-link mechanism, a second crank-link mechanism, an inner sieve box, an outer sieve box, a first suspension rod, a second suspension rod and a rack. The two sieve boxes are suspended on two four-link mechanisms by adopting the driving shaft provided with four eccentric sections and combining the two crank-link mechanisms with the two suspension rods, an elastic sieve screen composed of multiple small rectangular sieve plates is combined, and elastic flexure movement on the elastic sieve screen is caused to realize material sieve penetration while the two sieve boxes move relatively. The distributed driven type rocking sieve is high in complete reliability, good in combination property, smooth in movement, convenient to mount and position, simple in complete structure, convenient to maintain, energy saving, low in dynamic stress of a sieving machine and applicable to the fields of coal, metallurgy, chemical engineering, environmental protection and the like.

Description

technical field [0001] The invention relates to a distribution-driven oscillating screen, which is suitable for dry deep screening of moist fine-grained coal in a coal preparation plant, and also suitable for dry deep screening of other types of materials. Background technique [0002] The use of vibrating screens to separate coal has become an essential process in coal preparation plants, but vibrating screens are fragile, and deep screening often causes hole blocking. There are many kinds of vibrating screens currently in use, and the disadvantages of the various existing vibrating screens will be described below. [0003] The patent number is 97107249, and the patent named "multi-degree-of-freedom elastic collision screen and its screening method" provides an elastic rod multi-degree-of-freedom collision screen suitable for dry screening of fine-grained materials and its The screening method consists of a plurality of screen wires arranged on the screen frame to form a s...
