Abstract
The utility model belongs to a block eccentric oscillating screen with higher structural strength and life time in the screening machine. Aiming at the defect that the vibrator position of the vibration screen affects screen machine strength at present, the utility model is designed. The vibrator of the block eccentric oscillating screen is respectively arranged on one side plate of a screen box. A minor eccentric block is added. Simultaneously the beam structure on the lower surface of the screen plate is conducted to adjust. The strength and life time of the screen machine are increased. The height of the screen machine is reduced. The utility model can be used for screening single shaft and double shaft vibration screens for various materials.
Description
The utility model belong to have complete machine structure intensity height in the sieving machine, stress is good, the life-span is long piece eccentric vibrating screen.
Vibratory sieve is to drive a kind of plant equipment that screen box carries out screening operation by vibrator.The vibrator of vibratory sieve application at present mainly contains two kinds, and a kind of is eccentric shaft formula vibrator, and a kind of is box eccentric-type vibrator.The eccentric throw of eccentric shaft formula vibrator is less, and eccentric shaft is longer, should not process, and adjust also difficulty of amplitude; Box eccentric type vibrator is installed in the middle of the mounting rail above the vibratory sieve screen box, by mounting rail vibration force passed to screen box, and it is fragile that mounting rail and side plate junction stress are concentrated.Crossbeam flange under the compass screen surface also is a weak link with the pipe weld in addition, and cracking phenomena easily takes place.So the disadvantage of existing vibratory sieve is exactly stressed bad, should not develop to the maximization vibratory sieve.
The utility model is a kind of structural strength of vibratory sieve and the piece eccentric vibrating screen in service life of improving that designs at the deficiencies in the prior art.
The utility model is realized by following measure.The piece eccentric vibrating screen is made up of underframe, screen box, sieve plate, side plate, screen box crossbeam, vibrator assembly and motor, it is characterized in that: single-shaft vibrating screen has one group of vibrator assembly, two vibrators of vibrator assembly are separately positioned on two of screen box above the side plate, are connected with motor by universal drive shaft.Each vibrator all is made up of main eccentric block and secondary eccentric block, coaxial being installed on the vibrator shaft, and the angle between secondary eccentric block and the main eccentric block can be adjusted.Because the vibrator of this screen(ing) machine is arranged on two side plates of screen box, vibration force acts directly on the side plate of screen box, makes the whole stress of vibratory sieve good.By adjusting the angle of secondary eccentric block and main eccentric block, can adjust the amplitude of screen(ing) machine.
The dual-axis vibration sieve has two groups of vibrator assemblies, and two groups of vibrator assemblies have four vibrators, and two vibrators are installed respectively on each sieve box side plate, are connected with two groups of universal drive shafts by two motors.The compass screen surface of vibratory sieve adopts the splicing of standard module formula sieve plate, and installation and maintenance are convenient; The junction of sieve plate adopts strip flush type compounded rubber pressing plate to compress, and compass screen surface is smooth firmly; The tubular type crossbeam of fixed screen deck is by boss flange and sieve box side plate riveted joint below the sieve plate, and the boss of boss flange and the welding of tubular type crossbeam make weld seam away from area of stress concentration, have increased the bonding strength of screen box.
The utility model has the advantages that: vibrator is arranged on the side plate of screen box, adopt new technologies such as modularization sieve plate, take measures to have improved the structure of vibratory sieve from different perspectives, make the complete machine of vibratory sieve have characteristics such as stress is good, structural strength is high, the life-span is long.Can be widely used in sieving the single shaft and the dual-axis vibration sieve of various materials.
Accompanying drawing 1 is a structural representation of the present utility model, and (1) is the screen box crossbeam among the figure; (2) be sieve plate; (3) be bracing or strutting arrangement; (4) be sieve box side plate; (5) be the vibrator assembly; (6) be short universal drive shaft; (7) be motor; (8) be electric machine support; (9) be underframe; (10) be long universal drive shaft protective cover.
Accompanying drawing 2 is the structural representation of a vibrator in the utility model, and (4) are sieve box side plate among the figure; (10) be long universal drive shaft protective cover; (11) be long universal drive shaft; (12) be secondary eccentric block; (13) be main eccentric block; (14) be vibrator shaft; (15) be bearing block; (16) be bearing; (17) be the vibrator protective cover.
Accompanying drawing 3 is the structural representation of screen box crossbeam in the utility model, and (1) is the screen box crossbeam among the figure; (4) be sieve box side plate; (18) be the boss flange.
Below in conjunction with a description of drawings embodiment of the present utility model.Two piece eccentric type vibrators of vibrator assembly (5) are installed in respectively above the sieve box side plate (4), link together by long universal drive shaft (11), and are connected with motor (7) on the electric machine support (8) through short universal drive shaft (6).Vibrator is made up of main eccentric block (13), secondary eccentric block (12), vibrator shaft (14), bearing (16), bearing block (15) and protective cover (17).Main eccentric block (13) is installed on the vibrator shaft (14), and secondary eccentric block (12) is installed on the shaft shoulder of main eccentric block (13); Angle between secondary eccentric block (12) and the main eccentric block (13) can be adjusted.When motor start-up, drive vibrator assembly (5) by universal drive shaft (6) and (11) and make vibratory sieve work.The vibration force of vibrator assembly (5) acts directly on the side plate (4) of screen box, and machine stress is good.By adjusting the angle of secondary eccentric block (12) and main eccentric block (13), can adjust the amplitude of screen(ing) machine.The compass screen surface of vibratory sieve adopts standard module formula sieve plate (2) splicing, and installation and maintenance are convenient; The junction of sieve plate (2) adopts strip flush type compounded rubber pressing plate to compress, and compass screen surface is smooth firmly; The tubular type crossbeam (1) of fixed screen deck is by boss flange (18) and sieve box side plate (4) riveted joint below the sieve plate, and the boss of boss flange (18) and tubular type crossbeam (1) welding make weld seam away from area of stress concentration, have increased the bonding strength of screen box.
