Abstract
The utility model relates to an elevating conveyor aircraft nose uninstallation department secondary breaker. Its characteristics are: including install the belt in telephone -moving tail walking portion (4) and with elevating conveyor aircraft nose (2) but be connected move roller formula breaker (1) as an organic whole. The utility model discloses a secondary breaker is applicable to the colliery, and great mining height, easy wall caving are combined and are adopted, are combined and put the broken operation of the rectangular coal of working face transportation crossheading bold in the pit. It installs easy operation, has overcome the defect of influence production, and is efficient, and safe and reliable has promoted the development of comprehensive mechanization coal mining technique, is applicable to long -term abominable operational environment.
Description
Technical field
This utility model relates to secondary crushing device at a kind of frame head of reloading machine unloading.
Background technology
Along with the continuous lifting of coal production ability, and the sending out of fully mechanized coal winning technology, equipment
Exhibition, work surface corollary equipment the most perfect, work surface mining height by preferable 2～3.5 meters of scopes not
Disconnected increase, high seam working face mining length constantly increases simultaneously, and overlength working face mining increases relatively
Many, thereby result in Face Ground Pressure Behavior and substantially strengthen, wall caving and roof fall tendency aggravation, roof control
The problems such as difficulty increase.At high working face full-seam mining fully-mechanized mining working, structure big for hardness causes
For close, globality is strong, top coal is difficult to the coal seam of inbreak, the increase pressed with coal seam thickness and ore deposit, produce
Raw coarse coal diameter is even more than 1.5m.
For super high seam top coal caving, owing to caving coal height is relatively big, it is more likely formed coarse coal
(rock) inbreak；Coarse coal (rock), when conveyer is transported to coal circulation loading point, falls at elevating conveyor
After location disintegrating machine carries out primary fragmentation, part is suitable less than or equal to the strip coarse coal of disintegrating machine groove width
Coal flow path direction and transport at frame head of reloading machine, bulk strip coal can form coal stream through frame head of reloading machine
Retardance or fall directly into belt self-movable foot end by belt damages, causes the conveying, disintegrating apparatus cannot be just
Often transport, causes system-down, has a strong impact on the normal safe production and efficiency in colliery.At present, greatly
Mining and high comprehensive mining work surface occurs when bulk strip coal is stuck at frame head of reloading machine or strip coal damages belt,
All use after shutting down, crush by means of instruments such as manpower, pneumatic pick, crowbars, there is workman's work
The problems such as intensity is big, production efficiency is low, poor stability.
Utility model content
The purpose of this utility model is to provide secondary crushing device at a kind of frame head of reloading machine unloading, its behaviour
Work is simple, efficiency is high, safe and reliable, it is possible to enter the bulk strip coal at work surface frame head of reloading machine
Row second-time breakage.
Secondary crushing device at a kind of frame head of reloading machine unloading, it is particular in that: include being arranged on
The Mobile roller type connected as one on belt self-movable foot end running part and with frame head of reloading machine crushes
Machine.
Wherein Mobile roller type disintegrating machine includes crusher frame, and this crusher frame is arranged on belt certainly
On the walking track of movable foot end running part, and this crusher frame is also fixedly connected on frame head of reloading machine
On unloading port side；Also including actuating device, this actuating device is arranged on this by electric machine support and breaks
In broken machine frame, and this actuating device is also by drive mechanism and the broken roll shaft in crusher frame
Group is in transmission connection.
Secondary crushing device of the present utility model be applicable to underground coal mine high working face, easy wall caving combine adopt, combine
Put work surface haulage gate bulk strip coal crushing operation.Its installation is simple to operate, overcomes impact raw
The defect produced, efficiency is high, safe and reliable, promotes the development of comprehensive mechanical coal mining technology, is suitable for
In the most severe working environment.
Accompanying drawing explanation
Accompanying drawing 1 is use view of the present utility model；
Accompanying drawing 2 is that the P of Fig. 1 is to schematic diagram.
Detailed description of the invention
As shown in Figure 1, 2, this utility model provides second-time breakage at a kind of frame head of reloading machine unloading
Device, including being arranged on belt self-movable foot end running part 4 and being connected as one with frame head of reloading machine 2
The Mobile roller type disintegrating machine 1 of body.Wherein Mobile roller type disintegrating machine 1 includes crusher frame, should
Crusher frame is arranged on the walking track 3 of belt self-movable foot end running part 4, and this disintegrating machine
Frame is fixedly mounted on the unloading port side on frame head of reloading machine 2；Also include actuating device such as motor
And decelerator, this actuating device is arranged on this crusher frame by electric machine support, and this transmission
Device is in transmission connection also by the broken roll shaft group 6 of drive mechanism with crusher frame.
Using method of the present utility model and operation principle be:
As it is shown in figure 1, this utility model is bulk strip at a kind of work surface frame head of reloading machine 2 unloading
Coal secondary crushing device, including being arranged on belt self-movable foot end running part 4, with frame head of reloading machine 2
The Mobile roller type disintegrating machine 1 connected as one.The crusher frame of this Mobile roller type disintegrating machine 1
On with road wheel, can along belt self-movable foot end walking track 3 move together with frame head of reloading machine 2.
And actuating device is arranged on crusher frame by electric machine support, and it is arranged on crusher frame
On broken roll shaft group 6 and crusher frame collectively constitute this breaker.This breaker entirety is pacified
Being contained on elevating conveyor running part 4, crusher frame is in frame head of reloading machine 2 unloading port front, for work
Make face bulk strip coal and carry out second-time breakage, prevent bulk strip coal to be stuck in frame head of reloading machine 2 unloading port
Or fall directly into belt feeder tail by belt damages, thus cause the blocking of coal stream and shut down.This broken dress
Putting employing motor is power source, exchange general with the motor that colliery commonly uses, and has installation operation letter
Single, the features such as production efficiency is high, safe and reliable.
