Description
Technical field
The present invention relates to technical field of coal mine equipment, especially a kind of coal picker vibration for being able to extend the stagnant coal time
Sieve.
Background technique
Coal separation is also referred to as coal washing, and the process for meeting the cleaned coal of user quality requirement is sub-elected from raw coal.Coal for coking is to ash
Divide, sulphur content there are certain requirements, it is necessary to use the cleaned coal used Jing Guo washing.The lithofacies of coal form and the number of minerals in coal
Amount, type, property and distribution are all the factors for influencing the washability of coal.For the complexity of raw coal washability, coal separation
The common technique of factory has jigging, dense medium cyclone, dense-medium shallow-tank, vibro-assisted jigging, flotation etc..Other coal preparation methods there are also selection by winnowing,
Spiral separating etc..
However, existing coal picker, in coal separation, since raw coal directly slides from vibrating screen, the residence time is short, can not
Screening is sufficiently selected to it, could may thoroughly be distinguished by multipass screening with a collection of raw coal in this way, to cause coal separation work
Skill process cost height, increases the problem of worker's labor burden at low efficiency.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of coal picker vibrating screen for being able to extend the stagnant coal time, energy
It is enough effectively to increase the residence time of raw coal on the vibrating, full screening differentiation is carried out to raw coal, so that coal separation cost is reduced,
Coal separation efficiency is improved, worker's labor burden is reduced.
In order to realize the purpose for solving above-mentioned technical problem, present invention employs following technical solutions:
A kind of coal picker vibrating screen being able to extend the stagnant coal time, in the coal picker being obliquely installed for vibrating screen, from
Cleaned coal is screened in raw coal, it is characterized in that: arresting device is arranged on the vibrating, guarantees that raw coal is stranded on vibrating screen for a long time,
To sufficiently be screened to raw coal；
The arresting device includes frame, along shelves, crosspiece, rocker arm, pivoted arm and power device；It is mutually perpendicular to along shelves and crosspiece
Be arranged in frame, frame is divided into multiple areas Zhi Mei；Crosspiece is turnover panel of the more piece by axis connection, is equipped with phase along shelves
The axis hole answered；It is fixedly connected along shelves with frame, crosspiece can be overturn along shelves and relative to along shelves by axis connection；Crosspiece side is set
There is extension shaft, which passes through frame and extend out to outside frame；Pivoted arm is vertically set on extension shaft, which is equipped with item
Shape hole；One end of rocker arm is equipped with cylindrical section, which is arranged in the strip-shaped hole of pivoted arm, the other end and power device of rocker arm
Thrust axis be fixedly connected；Power device includes thrust axis, fixed plate, connector and electric pushrod, and electric pushrod passes through fixed plate
It is arranged in frame facet；Electric pushrod is removably fixedly connected with thrust axis by connector, and is able to drive thrust axis in water
It square moves reciprocatingly upwards；Arresting device setting is square on the vibrating, is fixedly connected by frame with vibrating screen.
Specific: the electric pushrod can be replaced with cylinder or hydraulic cylinder.
Application method: in use, trickling down raw coal in the area Zhi Mei of arresting device using transmission device, start coal picker
Make shaker vibration coal separation, when shaker vibration for a period of time after, start electric pushrod, then electric pushrod drive thrust axis receive
Contracting, thrust axis drive rocker arm to act backward, and the cylindrical section on rocker arm slides in the strip-shaped hole on pivoted arm, while forcing pivoted arm inverse
Hour hands rotation will drive crosspiece to rotate counterclockwise, at this time since pivoted arm is fixedly connected with the extension shaft of crosspiece while pivoted arm rotates
Turnover panel on crosspiece turns over, and slides the raw coal block in raw coal to the least significant end of vibrating screen along vibrating screen, drops down onto raw coal comb simultaneously
The coal picker is slid out along the guiding of raw coal comb, electric pushrod is then controlled and drives thrust axis stretching, extension, then thrust axis is by shaking
Arm and pivoted arm drive the turnover panel reduction on crosspiece, then carry out next wave raw coal screening；Using the vibrating screen, in actual operation,
The frequency that stoking frequency and electric pushrod drive thrust axis to move reciprocatingly in the horizontal direction, which need to only be controlled, can make the coal separation
Machine continues efficiently to work.
These technical solutions, including improved technical solution and further improved technical solution can also be combined with each other
Or combine, to reach superior technique effect.
By using above-mentioned technical proposal, the present invention has the following beneficial effects:
1, a kind of coal picker vibrating screen for being able to extend the stagnant coal time, not only stagnant coal effect is strong, and raw coal can be made to shake
Full screening differentiation, and high degree of automation are carried out on dynamic sieve, be easy to compared with coal picker cooperation, need to only pass through control
The stretching frequency of stoking frequency and electric pushrod can make coal picker continue efficiently to work, and conveniently adapt to the hair of coal separation modernization
Exhibition, reduces the labor burden of worker.
2, the electric pushrod of vibrating screen setting can be used in that crosspiece is driven to rotate counterclockwise, this is because on the one hand inclining
In the vibrating screen being tiltedly arranged, due to gravity, raw coal can be deposited in fastly above crosspiece, if rotating clockwise raw coal block will increase
The burden of electric pushrod, and crosspiece can be made to scoop up raw coal block, it is unfavorable for the downslide of raw coal block；And on the other hand, keep crosspiece inverse
Hour hands overturn the burden that can not only mitigate electric pushrod in the stress of crosspiece by the fast self-acting of raw coal, and then reduce function
Consumption moreover, the crosspiece turned counterclockwise does not influence the downslide of raw coal block not only, while can be also covered on above the raw coal block of downslide,
Stop the diffusion of dust, to assist reducing dust pollution caused by when raw coal block glides.
