Above four patent documentations all describe the improvement to decentralizing device from different angles, thus realize different object, reach certain Expected Results, but problem easy to wear does not still solve during decentralizing device work, this problem comprises: because bearing pin is stressed circularly, itself and adjustment plate disk hole junction is caused easily to loosen, after loosening, two parts rub easy to wear mutually, wearing and tearing arrive to a certain degree, adjustment plate, bearing pin all will be changed immediately, thus cause the use amount of adjustment plate excessive.
Summary of the invention
The invention provides a kind of eccentric device for plate feeder, solve the problem that when traditional rock feeder decentralizing device works, mechanical wear is excessive.
Technical scheme of the present invention is: a kind of eccentric device for plate feeder, comprises eccentric disk, platen, adjustment plate, drag link sleeve, bearing pin, pull bar; Its feature is that the right flank of eccentric disk is a shallow chamber that can just hold adjustment plate left surface, and adjustment plate is embedded in the shallow chamber of eccentric disk; On the right of adjustment plate, cylindrical is conical, matches with the platen of identical taper inner, and the circumferentially corresponding place of platen and eccentric disk is provided with circular hole, and standing screw passes circular hole and tightens up two dishes; Bearing pin interference fit is placed in disk hole, drag link sleeve and bearing pin free-running fit, and drag link sleeve freely can rotate around bearing pin; Disk hole, newly-increased disk hole one, newly-increased disk hole two, totally 3 disk hole are had in adjustment plate.
Adjustment plate in described a kind of eccentric device for plate feeder, the center of circle of disk hole, newly-increased disk hole one, newly-increased disk hole two is equilateral triangle distribution.Disk hole, newly-increased disk hole one, the newly-increased center of circle of disk hole two and the distance at adjustment plate center are all 58mm.
Traditional adjustment plate is provided with a disk hole in the place of range hadn wheel center 58mm, to connect bearing pin, drives drag link sleeve motion.Along with the wearing and tearing of disk hole in use procedure, the diameter of disk hole by increasing, the adjustment plate that must more renew when its diameter is greater than recommended minimum value time.This adjustment plate changing out is except wearing and tearing disk hole, and its remaining part is enough to design two qualities new disk hole suitable with adjustment plate disk hole.Such adjustment plate there are three disk hole, as long as rotate the angle of adjustment plate, just can realize the old and new's disk hole and substitute, and not affect the normal work of device, simultaneously serviceability and original adjustment plate indistinction.
At place, the adjustment plate original disk hole center of circle circumferentially, add two disk hole, three disk hole are made to be equilateral triangle distribution, when one of them disk hole diameter of adjustment plate be greater than recommended minimum value can not continue use time, another disk hole in available same adjustment plate is taken over it and is worked on, the time that such one piece of adjustment plate normally works is suitable with original three pieces of times that adjustment plate normally works, thus the adjustment plate that need not more renew immediately, thus improve Occupation coefficient and the service life of adjustment plate.

Detailed description of the invention
Below with reference to the accompanying drawings and the invention will be further described in conjunction with detailed description of the invention.
As shown in Figure 1, 2, plate belt feeder is linked in sequence by motor 1, reductor 2, two road axle 3 and decentralizing device 4 and forms, and decentralizing device 4 is connected with ratchet 6, ratchet 7 by pull bar 8.
As shown in Figure 3, decentralizing device structure of the present invention: adjustment plate 11 is embedded in the shallow chamber of eccentric disk 9, is built-in with disk hole 12, and bearing pin 14 is placed in disk hole 12; On the right of adjustment plate 11, cylindrical is conical, matches with the platen 10 of identical taper inner; The circumferentially corresponding place of platen 10 and eccentric disk 9 is provided with circular hole, and standing screw tightens up two dishes through circular hole; Bearing pin 14 interference fit is placed in disk hole 12, and drag link sleeve 13 free-running fit is in bearing pin 14, and drag link sleeve 13 freely can rotate around bearing pin 14.
As shown in Figure 4, traditional decentralizing device adjustment plate only has a disk hole 12.
As shown in Figure 5,6, adjustment plate of the present invention not only had disk hole 12 also to set up newly-increased disk hole 1 and newly-increased disk hole 2 17.
Mode of operation of the present invention is explained below in conjunction with accompanying drawing:
After switching on power, carrier bar is started working to the motor 1 in the system of ore deposit, and motor 1 drives reductor 2 by clutch, and reductor 2 drives two road axles 3 to rotate, and is fixed on decentralizing device 4 on two road axle 3 axle heads just around two road axle 3 center rotatings.The path of motion of the bearing pin 14 on decentralizing device 4 is exactly a circumference, thus the pull bar 8 be connected on the drag link sleeve 13 of bearing pin 14 produces the straight-line motion that moves in circles, thus drive ratchet 7 intermittent rotary by ratchet 6, power is obtained with the sprocket wheel filled on a shaft with ratchet, drive chain, carrier bar 5 move forward, nugget on carrier bar 5 is just pushed in crusher broken continually, and whole system is normally run.
In decentralizing device 4 working process, because bearing pin 14 is subject to the effect of pull bar 8 aspect load, easily loosen with coordinating of disk hole 12 in adjustment plate 11; Both phase mutual friction, wearing and tearing after loosening.When disk hole 12 is greater than technical index minimum requirements with the wear pattern of bearing pin 14, put back to original position after taking-up adjustment plate 11 rotates 120 degree and fix and change bearing pin 14, whole device just can work on.When the wear pattern of disk hole 12 is greater than technical index minimum requirements and bearing pin 14 function is intact, puts back to original position after adjustment plate 11 rotates 120 degree fix as long as take out, just can make System recover work.When only having the wear pattern of the disk hole 12 in adjustment plate 11, newly-increased disk hole 1, newly-increased disk hole 2 17 to be all greater than technical index minimum requirements, the adjustment plate 11 just more renewed.The times that the time that such one piece of adjustment plate 11 normally works normally works with original three pieces of adjustment plates 11 are suitable.
Eccentric device for plate feeder owing to having carried out to the adjustment plate 11 in single-deck hole 12 improvement adding two holes when life size is constant, thus extends service life, reduces productive costs.
