Description
Technical field
The present invention relates to technical field of coal mine equipment, especially a kind of coal picker vibrating screen.
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 of coal form 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, to cause coal separation work
Skill process cost is high, efficiency is low, increases the problem of worker's labour burden.
Invention content
Technical problem to be solved by the invention is to provide a kind of coal picker vibrating screens, can improve coal separation efficiency, drop
Low worker, which works, to bear.
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 in the coal picker being obliquely installed for vibrating screen, screens cleaned coal from raw coal, special
Sign is：Arresting device is set on the vibrating, ensures that raw coal is stranded on vibrating screen for a long time, to fully be screened to raw coal；
The arresting device includes frame, along shelves, crosspiece, electric pushrod, positioning sheath and connecting plate；It is mutual along shelves and crosspiece
Vertical is arranged in frame, and frame is divided into multiple areas Zhi Mei；It is fixedly connected with frame along shelves, crosspiece passes through frame facet
And it can be extracted out from frame；Sheath setting is positioned to be inserted into frame after passing through positioning sheath with crosspiece joint, crosspiece on the outside of frame；
Setting positioning sheath will not be shaken or fall off to make crosspiece when being extracted out from frame with electric pushrod；Connecting plate is located at frame
On the outside of frame, protrudes frame part with each crosspiece and connect；Electric pushrod is vertically set on frame lateral surface, piston rod and connecting plate
It is fixedly connected；Electric pushrod can drive connecting plate movement by piston rod, to drive crosspiece to extract out or insert from frame facet
Enter；The stroke of electric pushrod is equal with the width of frame；Arresting device setting is square on the vibrating, passes through frame and vibrating screen
It is fixedly connected.
Specifically：Electric pushrod in the arresting device can be substituted with hydraulic cylinder or cylinder.
Application method：In use, trickling down raw coal in the areas 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 piston rod stretch out band
Dynamic crosspiece is extracted out from the side of arresting device, and the raw coal block in raw coal is made to be slid to the least significant end of vibrating screen, in turn along vibrating screen
It is discharged outside vibrating screen, then shrinks the piston rod of electric pushrod and drive crosspiece reduction, then carry out next wave raw coal screening；It utilizes
This is equipped with the vibrating screen of arresting device, in practical operation, need to only control the stretching frequency of stoking frequency and electric pushrod
The coal picker is set to continue 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 advantageous effect below：
A kind of coal picker vibrating screen of the present invention, not only stagnant coal effect is strong, raw coal can be made to be filled on the vibrating
Point screening distinguish, and high degree of automation, be easy to compared with coal picker cooperation, need to only pass through and control stoking frequency and electricity
The stretching frequency of dynamic push rod can make coal picker continue efficiently to work, and conveniently adapt to the development of coal separation modernization, reduce worker
Labour burden.

Specific implementation mode
This patent is further explained below in conjunction with the accompanying drawings.But the protection domain of this patent is not limited to specifically implement
Mode.
Embodiment 1
As shown in the picture, a kind of coal separation vibrating screen of this patent, in the coal picker being obliquely installed for vibrating screen, from raw coal
Middle screening cleaned coal, it is characterized in that：Arresting device is set on the vibrating, ensures that raw coal is stranded on vibrating screen for a long time, to
Raw coal is fully screened.
Arresting device includes frame 6, along shelves 5, crosspiece 2, electric pushrod 3, positioning sheath 4 and connecting plate 1；Along shelves 5 and crosspiece 2
