Abstract
The utility model relates to a coal washery is with dividing screen machine specifically is a classifying screen pan feeding pendulum-type coal distributor. The technical problem of uneven feeding in the process that the scraper conveyor transports coal to the classifying screen is solved. The structure comprises a swing rod and a power device which are arranged on one side of the scraper conveyer, wherein the power device is connected with a rocker arm which is connected with the swing rod; a rotating shaft is arranged at the inlet of the screening machine below a coal leakage port of the scraper conveyor, a coal separating plate is arranged on the rotating shaft, a driving rocker arm is arranged at one end of the rotating shaft, and the driving rocker arm is connected with a swing rod through a driving connecting rod. The utility model discloses simple structure is practical, and the installation maintenance is easy, can effectively improve the pan feeding effect of classifying screen after using, guarantees that the cloth of sifting surface is even, improves screening efficiency, guarantees the good operation of screening equipment, is applicable to and improves the pendulum-type coal-splitting device of scraper conveyor to raw coal (or cleaned coal, waste rock etc.) classifying screen pan feeding in the washing processing field, guarantees that even stable pan feeding and screening machine sifting surface cloth are even.
Description
Technical field
The utility model relates to a kind of coal washery and uses screen-dividing machine, specifically is that a kind of classifying screen pan feeding pendulum-type is divided the coal device.
Background technology
Classifying screen is that general dressing of coal by washing equipment is used in the coal washery, and is common by behind the material inlet above drag conveyor conveying pan feeding coal to branch and the sieve, gets into classifying screen via slide coal tube and carries out the classification of raw coal or product in fact.Because coal stream is generally done parabolic motion, and classifying screen and the vertical layout of the normal work of scraper plate machine, whole compass screen surface cloth was extremely unbalanced after pan feeding arrived compass screen surface; The pan feeding coal accumulates in compass screen surface one side in a large number; Then along the compass screen surface width constantly successively decrease and, then cloth is few even do not have until opposite side, directly causes having coal one side to be difficult to ensure because of the excessive screening effect of coal amount; Screening machine has become " slide coal tube ", does not have coal one side and then does invalid screening running.And macrocyclic bad running also causes the sieve plate serious wear through regular meeting, and the equipment life cycle shortens.
Summary of the invention
The utility model provides a kind of classifying screen pan feeding pendulum-type to divide the coal device in order to solve scratch board conveyor fortune coal uneven technical problem of charging in the process of classifying screen.
The utility model is realized that by following technical scheme a kind of classifying screen pan feeding pendulum-type is divided the coal device, and structure comprises fork, the power set that are installed in scratch board conveyor one side, is connected with rocking arm on the power set, and rocking arm connects fork; Screen-dividing machine porch below the leakage coal mouth of scratch board conveyor is provided with rotating shaft, and rotating shaft is provided with coal separating plate, and an end of rotating shaft is provided with the driving rocking arm, drives rocking arm and is connected with fork through drive link.
The course of work of the utility model does, starts power set, and power set drive fork through rocking arm and seesaw with certain amplitude; The motion of fork simultaneously drives drive link and drives the rocking arm motion; Drive rocking arm and drive rotating shaft at last with coal separating plate swings back and forth, the coal of the parabolic motion track that falls from drag conveyor like this flows to be moved back and forth by coal separating plate to be broken up, and will become even dispersion coal supply; Effectively improved the uneven phenomenon of pan feeding, guaranteed that the cloth of compass screen surface is even.
The utility model is simple and practical; Installation and maintenance are easy, can effectively improve the pan feeding effect of classifying screen after the application, guarantee that the cloth of compass screen surface is even; Improve screening efficiency; Guarantee the good operation of screening plant, be applicable in the dressing of coal by washing field and improve the pendulum-type coal distributing device of drag conveyor, guarantee that uniform and stable pan feeding and screening machine compass screen surface cloth are even raw coal (or cleaned coal, spoil etc.) classifying screen pan feeding.
