Description
Technical field：
It is specifically a kind of that there is coarse coal precrushing the present invention relates to underground coal mine fully-mechanized mining working surface conveyer field
The lead-over groove and drag conveyor of function.
Background technology：
In underground coal mine fully-mechanized mining working, by periodic weighting and the combined influence disturbed, working face wall caving coarse coal are exploited
It is periodically caving, can be even caving in flakes when serious.Coarse coal falls into conveyer chute the normal fortune for not only influencing coal stream
It is defeated, and when reaching at conveyer head, it is difficult to be unloaded in conveyer unloading point, even if being unloaded on elevating conveyor, it is also difficult to
Into in the box conveying groove body at elevating conveyor entrance, it be easy to cause conveyer head position Severe blockage or even is forced to stop
Machine.At present, it after working face surface treatment coarse coal is mainly shut down by conveying equipment, manually crushes, clear up coarse coal, frequently
It opens, shut down the continuous exploitation for not only influencing working face, but also increase the labor intensity of worker in ground；Especially under shutdown status,
Transport is largely caving, it is easy to conveyer chute be caused to be crushed to death and can not restart, nothing in halted state if meeting wall caving coal
The workload that working face manually breaks coal and clear coal is increased in shape, the production efficiency of working face is seriously affected, further increases safety
Hidden danger is unfavorable for coal mine and realizes safety, exploits to high-yield and high-efficiency, and it is that fully-mechanized mining working is urgently to be resolved hurrily to solve coarse coal Crushing Problem
A great problem.
Invention content：
The purpose of the present invention is to provide a kind of lead-over grooves with coarse coal precrushing, solve conveyer chain-drive section
The problem of position coarse coal blocks.
Another object of the present invention is to provide a kind of drag conveyor, lead-over groove has the function of coarse coal precrushing,
It is crushed before coarse coal enters head unloading point, coarse coal is avoided to block head position, ensure the normal conveying of coal stream.
The technical solution adopted by the present invention is：A kind of lead-over groove with coarse coal precrushing, including transition groove body
6th, transition baffle 1, broken frame body 3, hydraulic cylinder 4, crushing roller 5, transition groove body 6 are equipped with connection ear C, connection ear D and connection
Plate 2, broken frame body 3 are hinged by pin 7 with the ear C that couples on transition groove body 6, and hinge joint is located at lead-over groove climbing the initial segment A,
4 one end of hydraulic cylinder is hinged with broken frame body 3, and the other end is hinged with the ear D that couples on transition groove body 6, crushing roller 5 and broken frame
Body 3 is welded formula structure.
Further, connection ear C, connection ear D and gusset piece 2 and transition groove body 6 are welded formula structure, and be respectively positioned on
The baffle side of transition groove body 6.
To achieve these goals, the present invention also provides a kind of drag conveyors, have bulk equipped with above-mentioned one kind
The lead-over groove of coal precrushing function.
Lead-over groove of the present invention has the function of coarse coal precrushing, is broken before coarse coal enters head unloading point
It is broken, coarse coal is avoided to block head position, ensure that the unimpeded of conveyer " throat " position, broken frame hinge joint is located at lead-over groove
At the initial segment of climbing A, installation site is relatively low, and worker is easy for installation, while but also crushing roller maximum height S obtains minimum
Value, even if in high working face thick coal-layer mining, crushing roller maximum height S also only has 3 meters or so, and the entirety for not influencing three machines is matched
Set.
The present apparatus is compact-sized, easy to operate, and the breaking size for realizing coal is continuously adjusted, and contributes to fully-mechanized mining working real
Now continuous exploitation, reduces the labor intensity and insecurity of hand breaking coarse coal, effectively meets coal mine fully-mechanized mining working
Soon adopt and push away soon the demand of fast freight.

Specific embodiment：
The specific embodiment that the present invention is carried out below in conjunction with attached drawing is described in detail：
As shown in Figs. 1-3, a kind of lead-over groove with coarse coal precrushing, including transition groove body 6, transition baffle 1,
Broken frame body 3, hydraulic cylinder 4, crushing roller 5, transition groove body 6 are equipped with connection ear C, couple ear D and gusset piece 2, connection ear C,
It is welded formula structure, and be located at the same side with transition baffle 1 to couple ear D and gusset piece (2) with transition groove body (6), is crushed
Frame body 3 is hinged by pin 7 with the ear C that couples on transition groove body 6, and hinge joint is located at lead-over groove climbing the initial segment A, in transition
The relatively low position of slot so that crushing roller maximum height S obtains smaller value, while is easily installed, safeguards, 4 one end of hydraulic cylinder with
Broken frame body 3 is hinged, and the other end is hinged with the ear D that couples on transition groove body 6, and gusset piece 2 is connected with head cable trough, crushes rolling
Cylinder 5 is welded formula structure with broken frame body 3.
Fig. 4 is the fluid power system schematic diagram of the present apparatus, hydraulic cylinder 4 is controlled to stretch out and shrink by operating valve set, real
The adjusting of 5 height of existing crushing roller, is connected to safety valve, when broken coal load has exceeded hydraulic cylinder allowed band in 4 epicoele of hydraulic cylinder
When, hydraulic cylinder drainage ensures that breaker is not destroyed.
The present invention operating method be：When working face coarse coal is caving more, according to working condition to coal cinder size
It is required that the height with working face conveying capacity adjustment crushing roller 5, starts crushing roller motor, coal cinder takes crushing roller to by scraper plate
5 lower sections will be broken after being in contact with it extruding, realize the continuous crushing of coarse coal on lead-over groove；If do not have whithin a period of time
When having the coarse coal to fall, crushing roller 5 can be turned up full blast a little and shut down, electricity is also saved while the transport of coal stream is not being influenced
Energy reduces the wear rate of equipment.
The detailed description carried out above by preferred embodiment to technical solution of the present invention is schematical rather than form
On limitation.Those skilled in the art, can be to the technology recorded in embodiment on the basis of description of the invention is read
Scheme, which is modified, either to be carried out which part technical characteristic equivalent replacement and these modifications or replaces, and is not made corresponding
The essence of technical solution is detached from the range of technical solution of the embodiment of the present invention.
