Example, is still one of indispensable basic energy resource in China, and Coal Mining Equipment Complement technology is to exploit thick and extremely thick coal
One of important mining type of layer.The characteristics of due to caving roof coal hydraulic support itself and the limitation of coal working face environment, after frame
The width of drag conveyor is restricted in design, and Sub-Level Caving is caused to have part coal during practical coal breakage along hydraulic pressure
The rear of drag conveyor after stent tail boom is shed to frame, it is impossible to be transported to outside well with drag conveyor, as Sub-Level Caving works
The continuous propulsion of face winning apparatus, this part coal are just retained in goaf, reduce the rate of recovery of coal mining, cause
The waste of coal resources.In addition, the coal shed in goaf is accumulated for a long time, spontaneous combustion is easily caused, to coal working face
It is unfavorable that safety in production is brought.
Utility model content
Coal mining recycling is improved at the rear of drag conveyor after being shed in dropping process to frame in order to avoid coal breakage
Rate reduces the possibility that the coal accumulation scattered causes spontaneous combustion, and the utility model offer is a kind of to have the function of that collection coal is adjusted
Drag conveyor after caving roof coal hydraulic support frame.
Technical solution：Have the function of it is adjustable collection coal caving roof coal hydraulic support frame after drag conveyor, belong to coal mine and open
Equipment technology field of transport is adopted, by drag conveyor, connect base, swing gate, oscillation adjustment hydraulic cylinder, telescopic baffle and is stretched
Contracting adjusts hydraulic cylinder composition.By bolt-connection, swing gate is vertical with connect base for connect base and drag conveyor chute
Plate upper end is hinged, and the cylinder body and piston rod of oscillation adjustment hydraulic cylinder are hinged respectively with the level board of connect base and swing gate.
There are sliding groove structure in swing gate both sides, and telescopic baffle is mounted in sliding slot, cylinder body and the piston rod difference of telescopic adjustment hydraulic cylinder
It is hinged with swing gate and telescopic baffle.
Connect base, swing gate and the telescopic baffle can be used according to comprehensive mechanized caving coal working face
Rear portion drag conveyor often save the length of chute and be changed to the connect base of corresponding length specification, swing gate and flexible gear
Plate.
The flexible of the piston rod of the oscillation adjustment hydraulic cylinder can change swing gate and the level board of connect base
Between angle, ranging from 0 ° to 45 ° of variable angle.
The telescopic baffle is mounted in the sliding slot of swing gate, and the flexible of telescopic adjustment hydraulic cylinder piston rod can make
Telescopic baffle is slided along the sliding slot of swing gate, realizes the stretching motion of telescopic baffle.
Drag conveyor is simple in structure after the caving roof coal hydraulic support frame for having the function of adjustable collection coal of the utility model,
Easy for installation, structural strength is high.By adjusting the angle of swing gate and the length of telescopic baffle, reduce drag conveyor after frame
Resistance during Forward is effectively prevented from the rear of drag conveyor after coal breakage is shed in dropping process to frame, improves coal
Recovery ratio, while avoid coal breakage and shed and be retained in the generation that goaf causes incidents of spontaneous combustion.

Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Drag conveyor after the caving roof coal hydraulic support frame for having the function of adjustable collection coal of the utility model, belongs to coal mine
Mining Transport equipment technical field, by drag conveyor 1, connect base 2, swing gate 3, oscillation adjustment hydraulic cylinder 4, flexible gear
Plate 5 and telescopic adjustment hydraulic cylinder 6 form.Connect base 2, swing gate 3 and telescopic baffle 5 can be according to comprehensive mechanization cavings
The length that rear portion drag conveyor 1 used in coal working face often saves chute is changed to corresponding length specification.Connect base 2 with
1 chute of drag conveyor is coupled by bolt 8, and swing gate 3 and the vertical panel 2-1 upper ends of connect base 2 are hinged, oscillation adjustment liquid
The cylinder body 4-1 and piston rod 4-2 of cylinder pressure 4 are hinged with the level board 2-2 of connect base 2 and swing gate 3 respectively, are adjusted by swinging
The flexible angle that can change between swing gate 3 and the level board 2-2 of connect base 2 of the piston rod 4-2 of hydraulic cylinder 4 is saved,
Ranging from 0 ° to 45 ° of variable angle.There are 8 structure of sliding slot in 3 both sides of swing gate, and telescopic baffle 5 is mounted in sliding slot 7, is stretched and is adjusted
The cylinder body 6-1 and piston rod 6-2 for saving hydraulic cylinder 6 are hinged with swing gate 3 and telescopic baffle 5 respectively, pass through telescopic adjustment hydraulic pressure
The flexible of the piston rod 6-2 of cylinder 6 can be such that telescopic baffle 5 is slided along the sliding slot 7 of swing gate 3, realize stretching for telescopic baffle 5
Contracting movement.During comprehensive mechanized caving coal working face coal breakage, can swing gate 3 be adjusted according to the thickness of coal breakage 10
Angle and telescopic baffle 5 extension elongation, make coal breakage 10 along telescopic baffle 5 and swing gate 3 be slipped to frame after scraper plate it is defeated
In the chute for sending machine 1, coal is transported into working face by drag conveyor after frame 1.With the propulsion of working face, work as comprehensive mechanization
