The utility model has the advantages of small size, high strength, small noise, less power consumption, good material flow, uneasy bin blocking, and explosion-proof property.

Description

Inertial oscillation feeder

The utility model belongs to a kind of charging gear, particularly a kind of inertia resonance vibrating vibrating feeder.

At present, in some production process of industries such as colliery, metallurgy, need raw material be fed or provide by technological requirement, this work is finished by feeding device, this kind equipment has use morning and commonplace common gate, structure and in-use performance are all relatively backward, and reciprocating type feeder, its shortcoming is that consumption of power is big, mechanical component are easy to wear, therefore maintenance capacity is big, and feeding coal can not be adjusted simultaneously, and equipment occupation space is big; To have a parts depreciation few for Fa Zhan electro-vibrating feeder afterwards, the advantage that power consumption is few, and to exchange noise big but exist, and big shortcoming takes up room; Development now with the internal-vibration type vibrating feeder of vibrating motor as vibration source, volume is little, and is in light weight, but service life is short, can not transfer to shake frequently and explosion-proof.

The purpose of this utility model is at the problems referred to above, and a kind of improved resonant vibrating feeder is provided, the advantage that it has adjustable frequency, noise is little, consumption of power is little, volume is little, mechanical component wear and tear less, long service life also can be explosion-proof.

The purpose of this utility model is achieved in that according to theory of oscillation, takes two particles resonant, and both motor separated the soruce of vibration of (disalignment) with oscillator, and the oscillator motion does not influence power of motor consumption; With the rubber spring spring that shakes of deciding, frequency ratio is 0.9, and near the work of resonance transformation point, amplitude can reach the 14mm(double-amplitude), reduced noise.Its structure: the bottom land bottom by the conveying cell body of shock absorber suspention is fixedly connected with forward and backward adapter plate, between forward and backward adapter plate, be fixedly connected with vibration excitor by rubber spring, activity is assembled with vibrating shaft on the vibration excitor, is assembled with the eccentric projection of fixing circumferential position and the adjustable complete cycle eccentric projection to the position on the vibrating shaft.Vibrating shaft is by the fire proof motor driven rotary that is fixedly connected on the vibration excitor shell.The vibration of vibration excitor generation drives the vibration of conveying cell body by rubber spring, and the amplitude of its vibration is realized by the circumferential position of adjustment adjustable eccentric projection and external motor control assembly with the frequency that shakes.

For improving the working strength of carrying cell body, be welded with the reinforcement arrangement of reinforcement in the lateral wall outside and the bottom of cell body; Be welded with the reinforcement arrangement of reinforcement on the forward and backward adapter plate equally; Be fixed with abrasion-proof backing block at the groove inside face; According to using needs, carry the bottom of cell body can make circular-arc or flat shape; Suspention carries the shock absorber of cell body for hanging blue shape, has been assembled with the rubber spring or the metal spring of damping of vibrations in it, carries cell body to be connected on rubber spring or the metal spring by hook.

Principle of work: machine operation, drive the vibrating shaft rotation of vibration excitor, vibration excitor produces vibration, and carries the cell body vibration by the rubber spring drive, and the material in the cell body, is evenly sent into material or is sent to front slide along the domatic bottom land.

Advantage of the present utility model: volume is little, and consumption of power is little, and noise is little, and oscillation frequency is adjustable, is difficult for stifled storehouse because the big streams of amplitude is had friendly relations, structure design intensity height simultaneously, and mechanical component are not easy to wear, long service life and have explosion-proof characteristics.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Fig. 2 is the right elevation of Fig. 1.

Fig. 3 is a structural representation of carrying cell body.

Fig. 4 is the birds-eye view of Fig. 3.

Fig. 5 is the structural representation of vibration excitor.

Referring to Fig. 1～5, with the conveying cell body 12 of metal sheet welding, its groove inside face is fixed with 19, three lateral wall outside weldings of abrasion-resistant metal liner plate the arrangement of reinforcement 13 of reinforcement, and its trench bottom is welded with the reinforcement arrangement of reinforcement 15 that interweaves in length and breadth; On the conveying cell body of bottom land bottom, be welded with band and strengthen the front mounting plate 4 and the back adapter plate 11 of arrangement of reinforcement 3.Vibration excitor 18 mainly comprises housing 21, vibrating shaft 1 and eccentric projection 22,23, vibrating shaft 1 is connected on the housing 21 by bearing, two eccentric projection 22 suits are fixed on the vibrating shaft 1, eccentric projection 23 suits are connected on the vibrating shaft 1, can and fix along circumferential adjustment position, thereby reach the purpose of adjusting amplitude.Fire proof motor 5 is fixedly connected on the housing 21, by drive belt 2 motor 5 and vibrating shaft 1 is in transmission connection; Rubber spring 20 is formed with folded mutually at interval bonding of metal sheet 16 or sulfuration by at least four layers rubber plate 17, and two rubber springs 20 are fixedly connected on vibration excitor 18 on front mounting plate 4 and the back adapter plate 11 by bolt.Carry cell body 12 to be suspended on the construction bracket, four safety ropes 9 are housed simultaneously by four bumper 10 domatics.Bumper 10 is to hang blue shape, its crossbeam 7 is suspended on the construction bracket, the rubber spring 6 that fold mutually more than three, cylindric, that the center is porose is housed in the bumper 10, the upper end of hook 8 is connected on the rubber spring 6, the lower end is connected carries on the cell body 12, carries the vibration of cell body 12 to carry out vibration damping by rubber spring 6.The rubber spring of bumper 10 also can be selected metal spring for use.For grasping the oscillation frequency situation of carrying cell body 12, frequency record instrument 14 is housed on cell body.

The oscillating feeder of this structure is convenient to automatic management and remote operation, can produce plurality of specifications as required. But 2000 tons of its medium-and-large-sized per hour feeds can satisfy instructions for use and functional, and cost is also on the low side.
