The fast development of generation science and technology, the requirement more and more higher to material distributing machine productivity ratio for the above-mentioned field, it is gradually increased 3000 t/h
Even up to 4000t/h above, for adapting to this demand, it is increasing that material distributing machine is also accordingly done, and wherein belt feeder calculates
Tension value increasing, according to《DTII（A）Design of belt conveyor handbook》, strainer is using common spiral tensioning device
Structure, application is very inconvenient.
Utility model content
The technical problems to be solved in the utility model is：Do bigger and bigger with material distributing machine, belt feeder therein calculates
Tension value is also increasing, and using common spiral strainer, application is very inconvenient, for solving the above problems, provides
A kind of reversible ring-like material distributing machine belt stretcher in coal delivery cylinder storehouse.
The purpose of this utility model is realized in the following manner：
A kind of coal delivery cylinder storehouse reversible annular material distributing machine belt stretcher, including being arranged on the snail match on belt tailstock
Bar and worm gear, are provided with attachment means between worm gear and drum shaft, worm gear drives drum shaft to move by attachment means.
Attachment means include the worm gear screw being sleeved in worm gear, and worm gear screw is connected with one end of screw mandrel, screw mandrel another
One end is connected with connector, and connector can drive drum shaft to move in the presence of worm gear and worm screw.
The nut being connected with screw mandrel is fixed with connector, one end that screw mandrel is connected with nut is provided with pin.
The two ends of drum shaft are provided with bearing, and bearing is arranged in stern roll bearing block, and belt tailstock is provided with confession
The guide rail of stern roll bearing block movement, connector is connected with stern roll bearing block by bolt.
With respect to prior art, the utility model adopts Worm Wheel System to drive drum shaft to move by attachment means,
Because the gearratio ratio of worm and gear is larger, on worm screw, the moment of torsion of transmission ratio is just much smaller with the moment of torsion that belt transmits, and grows up
Tensile force pass to reduced at worm gear, thus having reached labour-saving requirement.

Specific embodiment
As Figure 1-Figure 4, the reversible annular in a kind of coal delivery cylinder storehouse material distributing machine belt stretcher, including being arranged on belt tail
The worm screw 1 matched on frame 13 and worm gear 2, are provided with attachment means between worm gear 2 and drum shaft 10, worm gear 2 is filled by connection
Put drive drum shaft 10 mobile.Worm gear 2, worm screw 1 are arranged in the bearing 14 being connected with belt tailstock 13, on the two ends of worm screw 1
It is set with bearing I 17, bearing I 17 is arranged in setting bearing block I 16 on base 14, bearing 14 is provided with installation and fixes
The end cap I 15 of bearing I 17, end cap I 15 passes through bolt I 19 and installs on base 14.
Attachment means include the worm gear screw 3 being sleeved in worm gear 2, and worm gear 2 and worm gear screw 3 are connected by key 18, snail
Wheel screw 3 is connected with one end of screw mandrel 4, and the other end of screw mandrel 4 is connected with connector 5, and connector 5 is in the work of worm gear 2 and worm screw 1
With under drum shaft 10 can be driven mobile.The through hole that screw mandrel 4 passes through is provided with bearing 14, through hole is provided with installation snail
The bearing II 23 of wheel screw 3, bearing II 23 is sleeved in bearing block II 22, and bearing block II 22 is connected to bearing by bolt II 20
On 14, in the outside of bearing 14, through hole correspondence position is provided with end cap II 21, end cap II 21 is provided with what screw mandrel 4 passed through
Through hole, bolt II 20 connects end cap II 21, bearing 14 and bearing block II 22.
The nut 7 being connected with screw mandrel 4 is fixed with connector 5, one end that screw mandrel 4 is connected with nut 7 is provided with pin 8.
The two ends of drum shaft 10 are provided with bearing, and bearing is arranged in stern roll bearing block 9, and belt tailstock 13 is arranged
There is the guide rail 6 for stern roll bearing block 9 movement, guide rail 6 is arranged on the connecting plate of belt tailstock 13 by bolt, connector
5 are connected with stern roll bearing block 9 by bolt.Drum shaft 10 is structure as a whole with cylinder 11, and belt 12 is through on cylinder 11,
