Suitable for improving the coal picker of coal separation efficiency, high degree of automation
Technical field
It is particularly a kind of to be suitable for improving coal separation efficiency, high degree of automation the present invention relates to technical field of coal mine equipment
Coal picker.
Background technology
Coal separation is also referred to as coal washing, and the process for the cleaned coal for meeting 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 composition of coal and the number of minerals in coal
Amount, type, property and distribution are all the factors for the washability for influencing 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 also have 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 fully selected to it, may pass through multipass screening with a collection of raw coal in this way could thoroughly distinguish, so as to cause coal separation work
Skill process cost is high, efficiency is low, increases the problem of worker's labour burden.
Invention content
The technical problems to be solved by the invention are to provide a kind of coal picker, can effectively increase raw coal on the vibrating
Residence time carries out full screening differentiation to raw coal, so as to reduce coal separation cost, improves coal separation efficiency, reduces worker's labour
Burden.
In order to realize the purpose for solving above-mentioned technical problem, present invention employs following technical solutions:
A kind of coal picker, for screening cleaned coal from raw coal, it is characterized in that:Including pedestal, fastening bolt, adjust height devices,
Cleaned coal slideway, vibrating screen, vibrating motor, mounting bracket, arresting device and coal discharging apparatuses;
The pedestal is equipped with bolt hole, and fastening bolt passes through bolt hole to fasten pedestal on the ground;
The adjusting height devices are two hydraulic cylinders, and two hydraulic cylinders are vertically set on one end of pedestal;
Described cleaned coal slideway one end connects the piston rod of two hydraulic cylinders, and the other end is hinged with pedestal, and hydraulic cylinder can pass through work
The gradient of the telescopic adjustment cleaned coal slideway of stopper rod;
The vibrating screen is arranged on above cleaned coal slideway, and is connect with cleaned coal slideway by spring;
The vibrating motor is arranged on cleaned coal slideway side by mounting bracket, and vibrating motor is connect with vibrating screen, shakes for driving
Dynamic sieve vibration;
The arresting device includes frame, along shelves, crosspiece, positioning sheath, electric pushrod and connecting plate;It is mutually perpendicular to along shelves and crosspiece
Be arranged in frame, frame is divided into multiple Zhi Mei areas;It is fixedly connected along shelves with frame, crosspiece passes through frame facet and energy
It is enough to be extracted out from frame;Positioning sheath is arranged on the outside of frame to be inserted into after passing through positioning sheath in frame with crosspiece joint, crosspiece;Setting
It is to make crosspiece when being extracted out from frame with electric pushrod to position sheath, will not shake or come off;Connecting plate is located at outside frame
Side protrudes frame part with each crosspiece and connect;Electric pushrod is vertically set on frame lateral surface, and piston rod is fixed with connecting plate
Connection;Electric pushrod can drive connecting plate to move by piston rod, so as to which crosspiece be driven to extract out or be inserted into from frame facet;Electricity
The stroke of dynamic push rod is equal with the width of frame;Arresting device is arranged on above vibrating screen, is fixed by frame and vibrating screen
Connection;
The coal discharging apparatuses include cleaned coal comb and raw coal comb, and raw coal comb is arranged on cleaned coal comb top along vibrating screen direction
End, for discharging the blocky raw coal on vibrating screen;Cleaned coal comb is fixedly connected with cleaned coal slideway, and below vibrating screen, is used
In from the side of coal picker discharge cleaned coal slideway on cleaned coal.
Specifically:Electric pushrod available hydraulic cylinder or cylinder in the arresting device substitute.
Application method:In use, first cleaned coal slideway is adjusted to suitable slope using height devices are adjusted according to raw coal ingredient
Degree is discharged under the premise of making the gradient that can accommodate raw coal more as possible in the stagnant area for making arresting device convenient for the downslide of cleaned coal,
Specifically, if the cleaned coal in raw coal ingredient is more, the gradient for making cleaned coal slideway is larger, if the cleaned coal in raw coal ingredient is less,
The gradient for then making cleaned coal slideway is smaller, this is because cleaned coal slope of ways is big, then cleaned coal gliding speed is fast, convenient for the row of cleaned coal
Go out, the gradient of cleaned coal slideway is small, then more raw coal can be accommodated in the stagnant area of arresting device;Mix up the gradient of cleaned coal slideway
Afterwards, raw coal is trickled down in the arresting device of the coal picker using transmission device, Vibration on Start-up motor drives vibrating screen to shake at this time
Dynamic, then the cleaned coal in raw coal can leak through vibrating screen and fall on cleaned coal slideway, while be snapped down to the least significant end of cleaned coal slideway, by cleaned coal
Comb discharges the coal picker;After vibrating motor runs a period of time, start electric pushrod, then the piston rod of electric pushrod stretches out
Crosspiece is driven to be extracted out from the side of arresting device, the raw coal block in raw coal is made to be slid along vibrating screen to the least significant end of vibrating screen, is fallen
The coal picker is slid out to raw coal comb and along the guiding of raw coal comb, then shrinks the piston rod of electric pushrod and drives crosspiece
Reduction, then carry out next wave raw coal screening;The coal picker upon actuation, need to only control the flexible frequency of stoking frequency and electric pushrod
Rate can make the coal picker continue efficiently to work.
These technical solutions can also be combined with each other including improved technical solution and further improved technical solution
Or combine, so as to reach superior technique effect.
By using above-mentioned technical proposal, the present invention has following advantageous effect:
1st, not only coal separation is efficient for a kind of coal picker of the invention, but also can be suitable for the raw coal of heterogeneity, the scope of application
Extensively, with strong points, coal separation effect is good;
2nd, the coal picker is equipped with arresting device, and stagnant coal effect is strong, and raw coal can be made to carry out full screening differentiation on the vibrating;
3rd, the high degree of automation of the coal picker can make the coal separation by the stretching frequency for controlling stoking frequency and electric pushrod
Machine continues efficiently to work, and conveniently adapts to the development of coal separation modernization, reduces the labour burden of worker.
