Background technique

Activating feeder is widely used in thermal power plant coal handling system, is also applied for coal mine, harbour, mine, metallurgy, grain It is the special equipment for dosing in the material-transporting system of the industries such as food, coal chemical industry, harbour, building materials, especially suitable for Be arranged in below power plant coal scuttle, be the other forms such as inclined vibrator, belt feeder, revolving plow reclaimer, ring type coal unloading device to The ideal substitute products of material machine.

Activating feeder is driven using double mass Near resonance oscillating principle, in the start and stop stage because vibration shape wants across resonance band, For limit amplitude up to 4-6 times of normal condition, excessive amplitude has exceeded specification requirement at this time, influences equipment bulk life time.

Typically now amplitude is controlled by way of increasing damper, but this device can reduce the feed energy of equipment Power keeps its useful function impaired, and the damper restricted lifetime under activating feeder operating condition, needs to be replaced frequently.

Summary of the invention

Place, the utility model provide a kind of twin shaft inertia activating feeder in order to overcome the above-mentioned deficiencies of the prior art, The batcher is installed, is easy to use, and structure is simple, and amplitude when being fed function admirable and starting is small, improves equipment operation Stability and service life.

To achieve the above objectives, the present invention adopts the following technical solutions: a kind of twin shaft inertia activating feeder, including Equipment supporter, activating feeder ontology, isolation spring group, exciting vibration spring group, excitor, twin shaft inertial excitation source and adjusting dress It sets, the bottom of the activating feeder ontology is connect by isolation spring group with equipment supporter, and the one of the activating feeder ontology Side is connect with one end of exciting vibration spring group, and the other end of the exciting vibration spring group is connect with excitor, which is equipped with Twin shaft inertial excitation source, twin shaft inertial excitation source are electrically connected with regulating device.

In the above-mentioned technical solutions, twin shaft inertial excitation source include two vibrating motors and two eccentric blocks, every An eccentric block is connected on the output shaft of vibrating motor, and the rotation direction of two vibrating motors is on the contrary, aforementioned two vibrations are electric Machine is symmetrical relative to the mass center of activating feeder ontology.

In the above-mentioned technical solutions, two vibrating motors are in arrangement up and down.

In the above-mentioned technical solutions, two vibrating motors are in horizontally disposed.

The beneficial effects of the utility model are: elliptic of the motion profile of 1, activating feeder by common activating feeder It is reciprocating to become near linear, equipment start-stop stage condition is more stable；2, twin shaft inertial excitation source is turned round by synchronous backward Mode largely eliminate useless vibration using the principle of mass center conservation, remain useful vibration；3, such activation The more common activating feeder operating status of batcher is more stable, and feed adjustable extent is bigger, and the bulk life time period is longer；4, originally Utility model relative standard's activating feeder change it is small, be readily produced, can also to the activating feeder installed at the scene into Row transformation, it is strong that engineering promotes feasibility.

Specific embodiment

With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.

A kind of twin shaft inertia activating feeder, including equipment supporter 1, activating feeder ontology 2, isolation spring group 3, exciting Groups of springs 4, excitor 5, twin shaft inertial excitation source 6 and regulating device 7, the bottom of the activating feeder ontology 2 pass through vibration isolation Groups of springs 3 is connect with equipment supporter 1, and the side of the activating feeder ontology 2 is connect with one end of exciting vibration spring group 4, described to swash The other end of vibration groups of springs 4 is connect with excitor 5, which is equipped with twin shaft inertial excitation source 6, the twin shaft inertia Exciting source 6 is electrically connected with regulating device 7.Twin shaft inertial excitation source 6 passed through exciting groups of springs and transmitted linear vibration power To activating feeder ontology 2, is amplified by the Near resonance oscillating amplification of double mass and feedback vibration, large magnitude exciting force is transmitted to The top material of activating feeder ontology 2, the disturbance ability for vibrating generation make top material activating in fluidised form and fall to lower part Outlet, and the stable vibration track level of approximation straight reciprocating motion of activating feeder ontology 2.

In the above-mentioned technical solutions, twin shaft inertial excitation source 6 include two vibrating motors and two eccentric blocks, every An eccentric block is connected on the output shaft of vibrating motor, and the rotation direction of two vibrating motors is on the contrary, aforementioned two vibrations are electric Machine is symmetrical relative to the mass center of activating feeder ontology 2.Two vibrating motors are connect with regulating device 7 respectively, and regulating device 7 connects It is connected to PLC or control device, realizes the tune of exciting force by changing power frequency and the eccentric block angle of vibrating motor Section.Two vibrating motors select the motor with model, keep the vibration of two vibrating motors essentially identical, to more easily reach whole The dynamic balancing of body, and adjust simpler.
