The cross section of the strip through-hole 507 is arc, and strip through-hole 507 separates arc steel plate and lower separation for making
Radian increases when arc steel plate 505 stretches out；It is logical through bar shaped in upper separation arc steel plate and lower separation arc steel plate 505 when work
When hole 507 is stretched out, the inner wall phase at the top and 507 top of strip through-hole of upper separation arc steel plate and lower separation arc steel plate 505
Fitting, at this point, upper separation arc steel plate and lower separation arc steel plate 505 have curved trend downwards, in upper separation arc
When steel disc and lower separation arc steel plate 505 continue to stretch out, upper separation arc steel plate and lower separation arc steel plate 505 are pushed away far from arc
One end of plate 501 is bent downwardly, to may make that the bottom of lower separation arc steel plate 505 can be to the side close to the big spoil of diameter
To movement, the big spoil of diameter is separated with unbroken lump coal, upper separation arc steel plate separates the lump coal at the top of spoil
At multi-section point, the lump coal above spoil is avoided to fall together when spoil is fallen, so that it is unbroken to what is fallen to reduce the later period
Lump coal carry out broken workload.
The lower connected curved metal item 506 in the one end of separation arc steel plate 505 far from arc push plate；The curved metal
The curved direction of item 506 is with the lower bending direction for separating arc steel plate 505 on the contrary, the hardness of curved metal item 506 is less than lower point
Hardness from arc steel plate 505；When work, arc steel plate 505 is separated instantly and touches diameter big cash during stretching
The radian of Shi Shi, 506 bottom of curved metal item are big, at this point, the cambered surface of curved metal item 506 is capable of the top of diametrically big spoil
Portion is mobile, and the hardness of curved metal item 506 is lower than lower separation arc steel plate 505, at this point, curved metal item 506 it is easily-deformable with
Quickly the gap between the big spoil of unbroken lump coal and diameter is moved, and improves the work of lower separation arc steel plate 505
Efficiency reduces the amount of falling of unbroken lump coal when the big spoil of diameter is fallen.
When work, before start-up operation, oil cylinder 111 will be adjusted and be connected to an external hydraulic system, by No.1 hydraulic cylinder group
502 and No. two hydraulic cylinder groups 503 be connected to another external hydraulic system, pass through controller adjustment and adjust the flexible of oil cylinder 111
Length makes entirely to be crushed 105 surface of hinge and 118 surface of fixed jaw and reaches suitable angle, and motor 110 drives belt pulley
101 rotations, drive shaft 108 are followed by belt pulley 101 while rotating, and lump coal is entered in cabinet 115 by feed inlet, the drive of rotation
Moving gear 113 drives the entirely broken rotation of hinge 105, and 105 pairs of broken hinge enters lump coal and squeezed, rived, fractureed, ground
Four kinds of forms it is broken, reach the granularity of user's requirement.The big cash of hardness can be effectively avoided by hinge flexible connection
Stone damages crushing plant；When encountering the bigger spoil of diameter and can not be crushed, broken hinge 105 is caused by squeezing
Pressure rise adjusts pressure in 111 cylinder of oil cylinder and persistently increases, and when pressure reaches setting value in cylinder, safety valve is unloaded, and is adjusted
Fuel-economizing cylinder 111 is shunk, and increases broken the distance between hinge 105 and fixed jaw 118, spoil is fallen from discharge port, is played
Carry protection effect, can adjust oil cylinder 111 on sensor is set, for incuding the folding condition of safety valve, safety valve into
While row unloading, the signal sensed is transferred to controller by sensor, and controller controls No.1 hydraulic cylinder group 502 and No. two
Hydraulic cylinder group 503 works, and the speed of 502 output end of No.1 hydraulic cylinder group work is greater than No. two 503 output ends of hydraulic cylinder group
Operating rate, so that 501 top and bottom of arc push plate are in contact with the inner sidewall of fixed jaw 118 simultaneously, at this point, upper separation
Unit 504 and lower separation arc steel plate 505 are to the unbroken lump coal and diameter between fixed jaw 118 and broken hinge 105
Big spoil is separated into multiple portions, and the spoil that lower separation arc steel plate 505 can be big to diameter, is individually isolated, together
When, one end of upper separation arc steel plate and lower separation arc steel plate 505 can be mutually clamped with the crushing teeth on crushing shell 119, broken
Broken hinge 105 can release the big spoil of diameter when rotating, and broken hinge 105 be avoided to damage, upper separation arc steel plate with
When lower separation arc steel plate 505 is stretched out through strip through-hole 507, the top of upper separation arc steel plate and lower separation arc steel plate 505
It fits with the inner wall at 507 top of strip through-hole, at this point, upper separation arc steel plate and lower separation arc steel plate 505 have downwards
The curved trend in side, when upper separation arc steel plate and lower separation arc steel plate 505 continue to stretch out, upper separation arc steel plate is under
Separation arc steel plate 505 is bent downwardly far from one end of arc push plate 501, to may make the bottom of lower separation arc steel plate 505
Portion can separate the big spoil of diameter with unbroken lump coal, upper separation arc to close to the movement of the direction of the big spoil of diameter
Lump coal at the top of spoil is separated into multi-section point by shape steel disc, and the lump coal above spoil is avoided to fall together when spoil is fallen, when
When lower separation arc steel plate 505 touches diameter big spoil during stretching, the radian of 506 bottom of curved metal item
Greatly, at this point, the cambered surface of curved metal item 506 top of being capable of diametrically big spoil is mobile, and the hardness of curved metal item 506
It is lower than lower separation arc steel plate 505, at this point, curved metal item 506 is easily-deformable with quickly big along unbroken lump coal and diameter
Spoil between gap it is mobile, while material can be effectively avoided under gravity in the crushing device arranged vertically
Discharge port is blocked, after the big spoil of diameter is separated with broken hinge 105, controller controls to adjust oil cylinder 111 and resets, same to time control
Device control No.1 hydraulic cylinder group 502 and No. two hydraulic cylinder groups 503 processed reset, and hinge type crusher 1 continues work；
It is fallen on belt conveyor 3 by broken coal by discharge port, belt conveyor 3 transports to coal parallel
On 4 compass screen surface of vibrating screen, under the action of vibration excitor, vibrating screen can be rotated along X, Y, Z-direction vibration and around X-direction, on compass screen surface
Coal constantly from feeding end to discharging end motion, varigrained coal penetrates compass screen surface by corresponding sieve pore, to reach pair
The purpose that varigrained coal is sieved changes the inclination angle of compass screen surface, makes to shine by adjusting the collapsing length of electronic tie rod 408
The coal in face is evenly distributed, while four branch bearing capacitys in parallel are strong, and the adjustable control of the amplitude of vibration improves vibration
The effect of screening.
