Abstract
The utility model provides a complex excitation system for a resonance type vibration screen, and particularly relates to a resonance screen excitation system which is composed of an excitation row, an excitation row connecting rack and resonance springs which are arranged at the four corners below the excitation row connecting rack respectively. The resonance screen excitation system is used for solving the problem that an existing complex excitation system for the resonance type vibration screen is poor in reliability and is simple in structure, the springs which are parallel to the vibration direction of a screen machine are used for transmitting excitation force, the problem that the resonance springs are seriously abraded is solved, the fault rate of the complex excitation system can be greatly lowered, and normal operation of the resonance screen is guaranteed. Moreover, if the resonance screen excitation system is used as a supporting net device and a tensioning device, hook plates and fixing bolts used for connecting a screen frame and tensioning the supporting net can be reduced, the mass of vibration of a screen box combination is lightened, the work load of the springs for bearing the screen box combination weight is lowered, the service life of the resonance screen excitation system is prolonged, the fault hidden danger caused by looseness of the fixing bolts due to vibration in the using process can further be fundamentally eradicated, and thus the fault rate of the vibration screen is further lowered.
Description
Technical field
The utility model relates to a kind of resonance screens excitation system, and particularly a kind of complex excitation system of improved, resonant used by oscillating screen, belongs to separation equipment technical field.
Background technology
There is in recent years a kind of novel resonant vibratory sieve, this vibratory sieve, the surrounding of working net is connected with screen frame, below working net and with the working net resonance frame that be arranged in parallel, the outside of resonance frame is connected with the resonant spring that is fixed on screen frame inner side by end axle, in utilizing vibrating motor group to drive screen box to do straight-line oscillation, also utilize the inertia resonance of resonance frame to knock working net, make working net produce complex vibration, owing to taking into account good mass transport and saturating sieve ability and simple in structure, deeply be subject to fine to sieve industry-specific favor, but, owing to making working net produce the resonance frame combination of complex vibration---the design defect of complex excitation system by knocking: inconsistent for transmitting the axis direction of resonant spring and the direction of vibration of screen box of exciting force, cause resonant spring serious wear, spring obscission occurs again and again, have a strong impact on the normal operation of screen(ing) machine, therefore needing the resonance frame of this resonant used by oscillating screen to combine---the structure of complex excitation system is improved.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that overcomes the complex excitation system of above-mentioned existing resonant used by oscillating screen, and provide resonant vibratory sieve a kind of improved complex excitation system, it is a kind of resonance screens excitation system, to reduce the fault rate of resonant vibratory sieve, ensure that screen(ing) machine normally moves.
The technical scheme in the invention for solving the technical problem is:
A kind of complex excitation system of improved, resonant used by oscillating screen, it is a kind of resonance screens excitation system, 1 resonant spring by exciting row, exciting row's link (resonance frame) and four jiaos of each settings below exciting row link form, described resonant spring is column spring, uprightly installs, upper end by exciting arrange that upper spring supporting seat that link arranges and exciting arrange that link is connected below, lower end is fixed on the lower spring supporting seat being fixed on inside screen frame.
Above-mentioned resonance screens excitation system, described exciting package is drawn together and is arranged on respectively the fixing holder net exciting row at exciting row link two ends and is distributed in the supporting bracket net exciting row between two fixing holder net exciting rows, fixing holder net exciting row takes the shape of the letter U, being outside standing shape at the two ends of exciting row link installs, the bottom of outstanding exciting row link has holder net rivet clasp hole, and the supporting bracket net exciting row who is distributed between two fixing holder net exciting rows is a series of brace summers.
The complex excitation system of this resonant used by oscillating screen provided by the utility model, it is simple in structure, utilize the spring parallel with screen(ing) machine direction of vibration to transmit exciting force, solve the serious wear problem of resonant spring, can greatly reduce the fault rate of complex excitation system, ensure the normal operation of resonance screens.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but do not limit protection domain of the present utility model.
With reference to accompanying drawing, the utility model embodiment provides a kind of complex excitation system of improved, resonant used by oscillating screen, it is a kind of resonance screens excitation system, 1 resonant spring 5 by exciting row, exciting row's link 3 and four jiaos of each settings below exciting row link 3 form, described resonant spring 5 is column spring, uprightly installs, and upper end arrange by exciting upper spring supporting seat 4 that link 3 arranges below and arranged with exciting that link 3 is connected, lower end is fixed on the lower spring supporting seat 6 that is fixed on screen frame 9 inner sides; Described exciting package is drawn together and is arranged on respectively the fixing holder net exciting row 1 at exciting row link 3 two ends and is distributed in the supporting bracket net exciting row 2 between two fixing holder net exciting rows 1, fixing holder net exciting row 1 takes the shape of the letter U, being outside standing shape at the two ends of exciting row link 3 installs, the bottom of outstanding exciting row link 3 has holder net rivet clasp hole, and the supporting bracket net exciting row 2 who is distributed between two fixing holder net exciting rows 1 is a series of brace summers.
Adopt the resonant vibratory sieve of technique scheme, the former holder net 8 arranging that is connected with screen frame 9 by surrounding in working net (screen cloth) 10 times, two ends can be fixed on the fixing holder net exciting row 1 who installs at exciting row link 3 two ends with rivet 7, arrange the combination tensioning of arranging link with exciting by exciting.
Adopt the resonant vibratory sieve of above technical scheme, the axis of the resonant spring of complex excitation system is parallel with the straight-line oscillation direction of screen box, not only solve the serious wear problem of resonant spring, also alleviated the wearing and tearing to spring supporting seat, make excitation system work more reliable simultaneously; Owing to having reduced the drag hook plate and the set bolt that use for be connected setting and tensioning holder net with screen frame, not only can alleviate the mass of vibration of screen box combination, reduce the live load of the spring of carrying screen box combination quality, extend its service life, become flexible because vibration causes set bolt the potential faults bringing but also fundamentally got rid of in use procedure, the fault rate of vibratory sieve is further reduced.
