Description
Technical field
The present invention relates to Scraper Conveyor in Mining Face and transportation lane elevating conveyor, the overlapping side dump structure in especially a kind of Novel thin coal seam.
Background technology
At present, the shared ratio of the thin and ultra-thin coal seam in domestic particularly old mining area gets more and more.For avoiding the wasting of resources, realize resources balance exploitation.Each mining area has been strengthened thin and exploitation dynamics ultra-thin coal seam.For meeting the exploitation needs in each mining area, coal machine profession, for the particularly exploitation manufacture of the following ultra-thin coal seam fully-mechanized mining equipment of 1m of girdle, developed very swift and violent in recent years.
Existing thin coal seam scraper blade conveyor head unloading manner is all that end unloads form, because adopting end, handpiece of scraper conveyer unloads mode, cause conveyer head driving section on existing matching equipment, to exist many problems fully not solve, be mainly manifested in the following aspects: 1, power part adopts old man's side to be arranged vertically, cause face end support in crossheading to lag behind excessive to old man's side, cause this place to ventilate not smooth, supporting difficulty between termination frame and middle frame frame, easily causes danger.2, power part adopts rib side to be arranged vertically, and because thin seam working surface base plate and transportation lane base plate exist larger drop, coal-winning machine is in the time of head coal cutting, the fragile head power part of the coal that is scattered, and the coal of cutting off does not enter elevating conveyor, need artificial clear coal, labor strength is large.3, power part adopts and is arranged in parallel, and due to reducer profile impact, causes head, tail discharge height excessive.Conveyer head has taken the space of work plane top, in the time that face height changes, need cut at the end by force at head, the tail of conveyer, and workload is large.
Summary of the invention
The object of this invention is to provide the overlapping side dump structure in a kind of Novel thin coal seam, can realize the synchronizing moving of handpiece of scraper conveyer and elevating conveyor, and improved handpiece of scraper conveyer, transfer conveyor tail and hydraulic support arrangement space, thereby reduction head roadway support difficulty safety and the coal mining efficiency of work plane are improved.
The overlapping side dump structure in a kind of Novel thin coal seam, comprises conveyer and elevating conveyor, and its special feature is: at described transfer conveyor tail, unloading link slot is installed, the head of described conveyer is fixed on the unloading link slot of this transfer conveyor tail.
The wherein other coal-ploughing board that arc is installed of the conveyer head above unloading link slot, thus can make the transfer conveyor tail that turns to and then fall into below near the coal of conveyer head then be continued to carry by elevating conveyor.
Wherein conveyer head comprises headstock, sprocket shaft group is installed on this headstock, also comprise the power part being in transmission connection with this sprocket shaft group, this power part is arranged on the elevating conveyor middle trough baffle outside in rib direction, and this power part is parallel with this elevating conveyor middle trough baffle.
Wherein sprocket shaft group is arranged on elevating conveyor middle trough baffle outside.
Wherein also comprise hydraulic pressure height-regulating device, this hydraulic pressure height-regulating device is connected with the headstock of conveyer head and the unloading link slot of transfer conveyor tail simultaneously, thereby energy regulating frame head frame is with respect to the height of unloading link slot.
Technical scheme of the present invention, solve the unreasonable problem in power part installation site that the existing end mode of unloading causes, the hydraulic support hysteresis problems of too of avoiding end hydraulic support and work plane to arrange, the smooth problem of hydraulic support ventilation of avoiding end hydraulic support and work plane to arrange.Technical scheme of the present invention, by change head unloading manner, change handpiece structure, change the installation site of power part, improve conveyer head, transfer conveyor tail and hydraulic support arrangement space, reduced head roadway support difficulty, improved safety and the coal mining efficiency of work plane.

The specific embodiment
As shown in Figure 1,2,3, 4, the present invention is the overlapping side dump structure in a kind of Novel thin coal seam, comprise conveyer 8 and elevating conveyor 9, at described elevating conveyor 9 tails, unloading link slot 5 is installed, the head of described conveyer 8 is fixed on the unloading link slot 5 of these elevating conveyor 9 tails.The other coal-ploughing board 7 that arc is installed of conveyer 8 heads above unloading link slot 5, thus can make elevating conveyor 9 tails that turn to and then fall into below near the coal of conveyer 8 heads then be continued to carry by elevating conveyor 9.
Wherein conveyer 8 heads comprise headstock 1, on this headstock 1, sprocket shaft group 2 is installed, also comprise the power part 3 being in transmission connection with this sprocket shaft group 2, this power part 3 is arranged on the elevating conveyor 9 middle trough baffle outsides in rib direction, and this power part 3 is parallel with these elevating conveyor 9 middle trough baffles.Sprocket shaft group 2 is arranged on elevating conveyor 9 middle trough baffle outsides.Also comprise in addition hydraulic pressure height-regulating device 4, this hydraulic pressure height-regulating device 4 is connected with the headstock 1 of conveyer 8 heads and the unloading link slot 5 of elevating conveyor 9 tails simultaneously, thus energy regulating frame head frame 1 height with respect to unloading link slot 5.
Using method of the present invention is:
When use, coal stream moves to headstock 1 direction from the tail of conveyer 8, reach elevating conveyor 9 and unload the headstock 1 of link slot 5 top conveyer 8 heads when other when coal flows to, under the guide effect of coal-ploughing board 7, coal circulates to an angle of 90 degrees, directly drop to the tail of the elevating conveyor 9 that is located at headstock 1 below, thereby continued to carry by elevating conveyor 9.
The present invention is by changing the conveyer head principle of unloading coal, design the headstock of overlapping side dumping form, whole power part 3 is arranged on to the elevating conveyor 9 middle trough baffle outsides of rib direction, and compared with this overlapping side dumping structure unloads structure with former end, can share the parts such as the motor, reducer, sprocket shaft group 2 of same model, thereby reduce the kind of same model product.
As shown in Figure 1, 2, the present invention realizes first the overlapping side dumping of thin coal bed fully-mechanized mining working face conveyor and arranges, headstock 1 is designed to overlapping side dumping structure, in the time that coal stream material runs to above the unloading link slot 5 of elevating conveyor 9, change the traffic direction of material by the coal-ploughing board 7 on conveyer 8, thereby further material is unloaded on the unloading link slot 5 of elevating conveyor 9.By this change, can be by the Position Design of sprocket shaft group 2 rear at unloading port, thereby make the installation site of conveyer power part 3 that variation also occur.
As shown in Figure 3, below headstock 1, be designed with hydraulic pressure height-regulating device 4, by this device, headstock 1 and the unloading link slot 5 of elevating conveyor 9 linked into an integrated entity, realize the synchronizing moving of conveyer 8 and elevating conveyor 9, realize the adjustment of headstock 1 discharge height simultaneously.
As shown in Figure 4, the present invention is by changing the conveyer 8 heads principle of unloading coal, and the change of the installation site by power part 3 is arranged in conveyer 8 drive divisions the middle trough baffle side of the elevating conveyor 9 of rib direction, no longer takies the space of face end support.Also improve the arrangement space of conveyer 8 heads, elevating conveyor 9 tails and hydraulic support, face end support and work plane intermediate support 10 can be arranged in parallel, improve the ventilation situation of conveyer 8 heads and elevating conveyor 9 tails, reduce head roadway support difficulty, improve safety and the coal mining efficiency of work plane.
