Description

Electromagnetic vibration feeding machine with double tank-self balance function

The invention belongs to electric and magnetic oscillation feed machinery, can be widely used in the quantitative feed of bulk solid in the every profession and trade, powder and block material.

The electromagnetism feeding machine that prior art provided is widely used, but exists vice proper, promptly supporting base part or frame is had bigger obstacle of vibration.At present, all eliminate the method for this obstacle of vibration both at home and abroad in research.U.S. Pat 4405043 has adopted the method for bob-weight to eliminate external vibration.German patent DE3231947A1 has adopted the method for additional mass to keep the balance of electric oscillation feeding machine self.These methods can reach the self-balancing purpose, but all will consume invalid energy, can not improve feed efficient.And balance piece is a unmodified during owing to work, if inlet amount changes, then the self-balancing effect is influenced.In addition, vibrating direction angle can not change, and Applicable scope is restricted.

The objective of the invention is to design a kind of novel electricity feeding machine that shakes, both eliminated external obstacle of vibration, improve feed efficient again at above-mentioned defective; During work, the self-balancing effect stability; Vibrating direction angle is adjustable, and Applicable scope is wider.

Technical essential of the present invention is: the compound hopper that adopts center hopper in the same horizontal surface and binary hopper to constitute, two cell bodies are working material balance plastid each other again.Vibration excitor adopts no armature catamaran type structure, and two monomers are gone up hitch by two and linked with two cell bodies respectively.Go up the upper end that hitch is fastened on each autonomous vibration plate spring respectively for two.When passing to the periodicity exciting current in the vibration excitor, two cell bodies are made vibrate in opposite phase under the combined action of electromagnetic force and elastic force, the mutual balance of force of inertia.In addition, all adopt the adjustable angle structure between hopper and the last hitch and between lower link frame and the base, to adapt to different vibrating direction angle requirements.

Embodiment of the present invention as shown in drawings.Fig. 1 is multiple groove self-balancing electric and magnetic oscillation feeding machine A-A complete section front view, and Fig. 2 is a left view.Its chief component and principle of work are as follows: (11), (12) are respectively center hopper and binary hopper, do not contact mutually between them, constitute the similar single-groove multiple groove structure of profile.Two cell bodies weld with center brace panel (6) and binary brace panel (16) respectively.Two brace panels respectively with the center on hitch (1) and the binary hitch (2) link with screw is fastening.All having hole and garden arc groove with last hitch connection place on the brace panel, so that regulate the angle between them.Hitch is fastening with screw with the upper end of center master's vibration plate spring (13) and both sides master's vibration plate springs (14), (15) respectively on two.The lower end of each main vibration plate spring is anchored on shared lower link frame (9) again.Lower link frame (9) then is anchored on base (10).On the base and lower link frame connection place have hole and garden arc groove so that regulate angle between them.Base (10) links to each other with supporting mass by isolation spring (17).Electromagnetic exciter is no armature couple structure, and two monomers (3), (4) are anchored on hitch (1) on hitch on the binary (2) and the center respectively.The position of back vibration excitor (4) can be adjusted by double end adjusting screw(rod) (7), so that obtain suitable magnetic pole air gap.Binary hopper assembly (comprise brace panel, go up hitch) is discontiguous to be passed center hopper assembly and fuses.Quality adjustment piece (8) is equipped with at the rear portion of hitch on the center (1), changes the size of (8), the mass ratio of scalable two hopper assemblies.When the vibration excitor coil passes to exciting current, produce excitatory power, make main vibration plate spring distortion, two cell body assembly relative motions; When exciting current disappeared, the elastic restoring force of main vibration plate spring made two hopper assembly counter motions again.Like this, under the combined action of excitatory power and elastic force, two hopper assemblies just produce vibrate in opposite phase, finish the feed function.Because it is the same that the quality of two hopper assemblies is adjusted, their the center plane of symmetry overlaps again, thus the mutual balance of its force of inertia during work, externally friction interference.When changing electrical quantity, the amplitude of changeable trough or frequency are with the control feeding speed.Because two hoppers are at same horizontal surface and Way out unanimity (see Fig. 1, by right-hand charging, left discharging), thus can be to same hopper feed, and it is convenient as single groove to use.Because two hopper charging position unanimities, during charging, two hopper mass change are in the same way, so do not influence the self-balancing effect.In the time of need changing vibrating direction angle as different material, as long as unscrew between brace panel and the last hitch and the tightening screw between base and the second line of a couplet fishplate bar, promptly adjustable-angle is very convenient.

Compared with prior art, the present invention has following features:

1, adopts multiple groove self-balance method, both can eliminate external vibration interference, significantly improve again feed efficient, also avoided excess energy consumption (cancellation balance weight part);

2, because center hopper and binary hopper in same horizontal surface, and are imported and exported the position unanimity, thus both can be to same hopper feed, when making in the work charging again, two vibrate the hopper mass change in the same way, and the self-balancing effect is more stable;

3, owing to adopted no armature binary vibration excitor, disturbance force improves, volume-diminished, and structure is more reasonable;

4, visual material properties is different and change vibrating direction angle, has enlarged the machine applicable area;

5, owing to cancelled additional balance piece, weight alleviates greatly.
