Description

External self-synchronous jigging feeder

The utility model relates to a kind of under feed bin, the novel big ability feeding device of even feeding on the continuous conveyor.

At present both at home and abroad under feed bin, the kind of even feeding equipment is a lot of on the continuous conveyor, as belt, board-like, vane type, garden disc type, reciprocating type, electric and magnetic oscillation and motor oscillating feeder etc.Using extensivelyr at China reciprocating feeder, is the technology that the fifties is introduced from the Soviet Union, divides coventional type and explosion proof type two classes, maximum feed ability be 600 cubic meters/hour.Along with the progress of world technology and the development of Chinese national economy, large-scale mine and equipment emerge in large numbers rapidly, and it is outmoded that the oldfashioned reciprocating feeder has shown, and the feed ability does not satisfy the requirement of large-scale corollary equipment yet.The motor oscillating feeder is the energy-saving feeding device that grows up according to foreign technology in recent years.It is to adopt special vibrating motor, and promptly motor two ends shaft adds eccentric block and produces disturbance force at the shaft place, and the domestic and international manufacturer of this kind equipment is more.State-of-the-art in the world at present is West Germany, its maximum feed ability have only 800 cubic meters/hour, China has introduced one.But the feed ability does not still satisfy needs, and does not have explosion proof type, has limited its range of use.

For addressing this problem, common way is to strengthen the disturbance force and the power of vibrating motor, manufactures experimently new and explosion proof type vibrating motor.But the disturbance force of expanded motor and power, for guaranteeing the service life of motor, must strengthen bearing designation, increase and shaft diameter, must reduce the basal area of rotor field for this reason, satisfy the required parameter value of motor, will increase the oad and the deadweight of motor, promptly increased the mass of vibration of equipment, made it reach big feed ability and have very big difficulty.

The purpose of this utility model is that a kind of later-model big ability feeding device will be provided, and will satisfy the requirement of coventional type and explosion proof type simultaneously.

The purpose of this utility model is achieved in that employing external electromagnetic shaker, and its eccentric oscillating component separates with motor, and the centre connects with coupling with rubber type element.Eccentric oscillating component and motor are contained in respectively on vibrating bunker and the fixed chute that separates with vibrating bunker, motor is not joined shake.When need strengthen disturbance force, only need to strengthen eccentric block quality and bearing designation, it is limited that mass of vibration is increased, and improves the feed ability and be easier to.Simultaneously, owing to need not manufacture experimently special vibrating motor,, just can satisfy the requirement of coventional type or explosion proof type as long as load onto national energy-saving Y or YB series asynchronous motor by power requirement.

The utility model separates oscillating component and motor because only need vibration source is made external, and the centre connects with coupling with rubber type element, just can separately its oscillating component be contained on the vibrating bunker, motor is not joined shake, and reduces its mass of vibration, improves the feed ability.Simultaneously, also can select national Y or YB serial motors for use, need not manufacture experimently special vibrating motor, just can realize improving the feed ability and form coventional type or explosion-proof type equipment.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is according to the external self-synchronization vibration feeder sketch that the utility model proposes.

Describe details and service condition in detail below in conjunction with Fig. 1 according to the concrete equipment that the utility model proposes.

This equipment comprises fixed chute (1), isolation mounting (2), vibrating bunker (3), external electromagnetic shaker (4) and damping arrangement (5) totally five parts.

Material gets off through fixed chute (1) to vibrating bunker (3) from feed bin, because two external electromagnetic shakers (4) are done the reverse sync running, the drive eccentric block rotates, vibrating bunker (3) is produced the disturbance force of vertical stack, transverse force is cancelled each other, and realizes the self timing operation, forces vibrating bunker (3) to produce simple harmonic oscillation under super resonance condition, material on the material on the vibrating bunker (3) is dished out along parabola, finish the feed action.Isolation mounting (2) is to make vibrating bunker (3) under the effect of external electromagnetic shaker (4) disturbance force, obtains certain amplitude and Equipment Foundations are played the vibration isolation effect.Damping arrangement (5) is when device start or when stopping resonance range, plays shock damping action, makes it smoothly by resonance range, in case equipment and foundation failure.

Claims

1, under feed bin on the continuous conveyor external self-synchronization vibration feeder of feed, it is characterized in that this equipment has a fixed chute (1), four isolation mountings (2), a vibrating bunker (3), two external electromagnetic shakers (4), four damping arrangements (5).

2, according to claim one, it is characterized in that having the propulsion source of two external electromagnetic shakers (4) as this equipment, its eccentric oscillating component separates with motor, the centre is connected by coupling with rubber type element, eccentric oscillating component is contained on the vibrating bunker (3), motor then is contained on the fixed chute (1) that separates with vibrating bunker (3), motor is not joined shake, so can improve the feed ability.

3, according to claim one or two, not needing it is characterized in that special vibrating motor, adopt the external electromagnetic shaker, oscillating component and motor are separated, therefore, only need load onto Y or YB serial motors, just can be made into coventional type or explosion-proof type equipment.

4, according to claim one, it is characterized in that isolation mounting (2) has adopted the rubber isolation spring, its vibration isolating effect is good, and noise is low.

5, according to claim one, it is characterized in that damping arrangement (5) makes equipment play shock damping action when starting and stopping resonance range, guarantees that this equipment can pass through resonance range reposefully.
