Abstract
Caving roof coal hydraulic support rear portion drag conveyor collection device for coal, belongs to coal mining equipment technology field of transport.The device includes connect base, swing gate, oscillation adjustment hydraulic cylinder, telescopic baffle and telescopic adjustment hydraulic cylinder.Swing gate is hinged with connect base, and the cylinder body and piston rod of oscillation adjustment hydraulic cylinder are hinged with connect base and swing gate respectively.Swing gate both sides have sliding groove structure, and telescopic baffle is arranged in the chute of swing gate, and telescopic adjustment hydraulic cylinder piston rod is hinged with telescopic baffle, and telescopic adjustment hydraulic cylinder body is hinged with swing gate.The collection device for coal is coupled by bolt with drag conveyor.By adjusting the angle of swing gate and the length of telescopic baffle, coal breakage is shed in dropping process to the rear of rear portion drag conveyor during being effectively prevented from Coal Mining Equipment Complement, coal mining rate is improved, while avoids and scatters the generation that the coal for being retained in goaf causes incidents of spontaneous combustion.
Description
Technical field
The present invention relates to a kind of coal mining transporting equipment, and in particular to a kind of caving roof coal hydraulic support rear portion scraper plate conveys
Machine collection device for coal.
Background technology
Coal is the important foundation energy in China, and various industrial departments will consume substantial amounts of coal every year.Although coal
Consumption ratio, which was focused in the coming years, have been declined, but consumption of coal primary energy consumption in still in occupation of huge ratio
Example, is still one of indispensable basic energy resource in China.Coal Mining Equipment Complement is exploitation thickness and pole high seam
One of important mining type, the mining type have stronger adaptability to coal seam and geological conditions, can carry out and adopt, are laid flat capable work
Industry, the mining rate in coal seam is added, simplify production link and greatly reduce tunnelling and maintenance workload, realize
The high concentration metaplasia production of mine, has significant economic benefit.But the mining type has coal mining rate relatively low, work
It is big to make flour dirt, the shortcomings of spontaneous fire and larger methane accumulation hidden danger.During Coal Mining Equipment Complement, due to
Caving roof coal hydraulic support rear portion drag conveyor limited width, during coal is put, substantial amounts of coal scatters to be scraped top coal at rear portion
The rear of plate conveyer, cause the waste of coal resources.In addition, with the continuous propulsion of comprehensive mechanization Sub-Level Caving equipment,
The coal for being retained in rear portion drag conveyor rear is retained in goaf, the major safety risks that spontaneous fire be present, to coal
It is unfavorable that the safety in production of ore deposit coal-face is brought.
The content of the invention
In order to improve the raw coal recovery ratio of Coal Mining Equipment Complement working face, top coal is avoided to be spread during coal is put
Fall the hidden danger of the waste at the rear of rear portion drag conveyor, causing coal resources and spontaneous combustion in goaf, the present invention carries
For a kind of caving roof coal hydraulic support rear portion drag conveyor collection device for coal, the device is provided with swing gate and telescopic baffle, can be with
Effectively the coal breakage to be fallen in recovery process is guided into the chute of rear portion drag conveyor, avoids top coal caving process
The coal breakage of middle whereabouts is shed to the rear of rear portion drag conveyor.
Technical scheme：Caving roof coal hydraulic support rear portion drag conveyor collection device for coal, belongs to coal mining transporting equipment skill
Art field.The device includes connect base, swing gate, oscillation adjustment hydraulic cylinder, telescopic baffle and telescopic adjustment hydraulic cylinder.Pendulum
Dynamic baffle plate is hinged with connect base, and the cylinder body and piston rod of oscillation adjustment hydraulic cylinder are cut with scissors with connect base and swing gate respectively
Connect.Swing gate both sides have sliding groove structure, and telescopic baffle is arranged in the chute of swing gate, telescopic adjustment hydraulic cylinder piston
Bar is hinged with telescopic baffle, and telescopic adjustment hydraulic cylinder body is hinged with swing gate.The collection device for coal is defeated with scraper plate by bolt
Machine is sent to couple.
The width of described collection device for coal is consistent with the length of drag conveyor chute, is conveyed according to used scraper plate
The length of machine chute, the collection device for coal of different in width specification can be installed.
The flexible of the piston rod of described oscillation adjustment hydraulic cylinder can change between swing gate and connect base plane
Angle, variable angle scope be 0 ° to 45 °.
Described telescopic baffle is arranged in the chute of swing gate, and the flexible of telescopic adjustment hydraulic cylinder piston rod can make
Slide of the telescopic baffle along swing gate, realize the stretching motion of telescopic baffle.
The caving roof coal hydraulic support rear portion drag conveyor collection device for coal of the present invention is simple in construction, easy for installation.The device
Provided with swing gate and telescopic baffle, by adjusting the angle of swing gate and the length of telescopic baffle, will effectively exploit
The coal breakage to be fallen in journey is guided into the chute of rear portion drag conveyor, is avoided the coal breakage to be fallen during top coal caving and is thrown
Spread to the rear of rear portion drag conveyor, improve coal mining rate, while avoid and scatter the coal for being retained in goaf and draw
Play the generation of incidents of spontaneous combustion.
Brief description of the drawings
Fig. 1 is the caving roof coal hydraulic support rear portion drag conveyor collection device for coal structural representation of the present invention.
Fig. 2 is swing gate, telescopic baffle and sliding groove structure schematic diagram.
Fig. 3 is the caving roof coal hydraulic support rear portion drag conveyor collection device for coal scheme of installation of the present invention.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
The caving roof coal hydraulic support rear portion drag conveyor collection device for coal of the present invention, belongs to coal mining transporting equipment technology
Field.The device includes connect base 1, swing gate 2, oscillation adjustment hydraulic cylinder 3, telescopic baffle 4 and telescopic adjustment hydraulic cylinder
5.Swing gate 2 and connect base 1 are be hinged, the cylinder body 3-1 and piston rod 3-2 of oscillation adjustment hydraulic cylinder 3 respectively with connect base 1
It is be hinged with swing gate 2.The both sides of swing gate 2 have the structure of chute 6, and telescopic baffle 4 is arranged in the chute 6 of swing gate 2,
The piston rod 5-2 of telescopic adjustment hydraulic cylinder 5 is be hinged with telescopic baffle 4, and the cylinder body 5-1 of telescopic adjustment hydraulic cylinder 5 is cut with scissors with swing gate 2
Connect.The collection device for coal 8 is coupled by bolt 9 with drag conveyor 10.
During Coal Mining Equipment Complement operation, according to the thickness in the dropping process of coal breakage 7, the collection device for coal 8 is adjusted
