A square rotating shaft is arranged on a rack; a square rotating hole cooperating with the rotating shaft is arranged in the middle of a rocker arm; a buffering rubber strip is arranged between the rotating shaft and the rotating hole; an installing hole is arranged in the middle of the rotating shaft; an inner expansion body and an outer expansion body are successively arranged in the installing hole; an anti-falling cover plate is correspondingly arranged on the outer side of the installing hole; holes are arranged in the middle of the anti-falling cover plate and in the middles of the inner and outer expansion bodies; a bolt successively penetrates through the anti-falling cover plate, the outer expansion body and the inner expansion body and is in tight fit with the inner expansion body; and mutually contacted end faces of the inner and the outer expansion bodies are matched cooperative inclined planes. The anti-falling machine is simple in structure and practical, a falling problem of the buffering rubber strip in the vibration conveyer rocker arm can be effectively solved, and accidents caused by falling of the rocker arm is prevented.
Description
Technical field
The utility model relates to a kind of jigging conveyer rocking arm anti-drop device.
Background technology
Jigging conveyer is widely used in the mass transport in redrying, the processing of throwing line segment tobacco, and play simultaneously and vibrate effect loose, screening materials carrying, be that tobacco produces indispensable important auxiliary equipment.Rocking arm plays connection, supports cell body and balanced body in jigging conveyer, and the effect of transmission of drive force, balance vibrations.The swing of rocking arm operation main body swing arm, strut bar play fixed supporting role, and four bumper rubbers play shock absorbing effect.When adhesive tape is aging, wear and tear produces gap between back support rod and swing arm, can cause swing arm or adhesive tape outwards to deviate from.The generation of the fault such as often cause that because adhesive tape is aging rocking bar, adhesive tape mechanicalness are deviate from, dropped in actual use, and cause many faults and potential safety hazard.(1) rocking arm use amount is large, and deviating from, dropping of rocking bar, adhesive tape is irregular, and preventive maintenance difficulty is high, work capacity is large, causes production run fault interrupting; (2) when rocking arm rocking bar, adhesive tape are installed in high-altitude, easily cause the object tramp material material that comes off, cause the generation of pipe tobacco foreign material accident; (3) install and lower visit, when the rocking bar of the rocking arm at maintenance channel position, adhesive tape, return and cause personal safety or damage potential safety hazard.
Utility model content
The utility model provides a kind of jigging conveyer rocking arm anti-drop device, bumper rubber position can be fixed and be unlikely, drop, and the safety of support equipment, reduces safety misadventure hidden danger.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: jigging conveyer rocking arm anti-drop device, frame is provided with square rotating shaft; rocking arm middle part is provided with the square hole that turns coordinating with rotating shaft; in rotating shaft with turn the bumper rubber that is provided with between hole; rotating shaft middle part is provided with mounting hole; in mounting hole, be provided with successively inside and outside expander; outside mounting hole, correspondence is provided with anticreep cover plate; anticreep cover plate and inside and outside expander middle part are provided with hole; bolt shank passes anticreep cover plate, outer expander, interior expander setting successively, and screws and coordinate with interior expander.
The end face that inside and outside expander is in contact with one another is the inclined-plane that matches and coordinate.
Mounting hole is square, and inside and outside expander vertical section is square.
The diameter in the hole that interior expander middle part arranges is suitable with bolt shank diameter, and the diameter in the hole of outer expander middle part setting is greater than the diameter in the hole arranging in the middle part of interior expander.
Slip-off preventing cover plate can play the effect of fixing bumper rubber, ensures that adhesive tape there will not be the phenomenon dropping, and bolt shank coordinates inside and outside expander, and inside and outside expander is fastened in mounting hole.
The utility model is simple in structure, practical function, can actv. solves the problem that comes off of bumper rubber in vibration transmission machine rocking arm.Prevent because of the rocking arm safety misadventure causing that comes off.

Detailed description of the invention
Embodiment: as shown in Figure 1, jigging conveyer rocking arm anti-drop device, frame 3 is provided with square rotating shaft; Rocker arm 4 middle part is provided with the square hole that turns coordinating with rotating shaft; in rotating shaft with turn the bumper rubber that is provided with between hole; rotating shaft middle part is provided with mounting hole; in mounting hole, be provided with successively interior expander 6, outer expander 7; outside mounting hole, correspondence is provided with anticreep cover plate 8; anticreep cover plate 8 and interior expander 6, outer expander 7 middle parts are provided with hole; bolt shank 9 passes successively anticreep cover plate 8, outer expander 7, interior expander 6 and arranges, and screw and coordinate with interior expander 6.The end face that interior expander 6, outer expander 7 are in contact with one another is the inclined-plane that matches and coordinate.Mounting hole is square, and interior expander 6, outer expander 7 vertical sections are square.The diameter in the hole that interior expander 6 middle parts arrange is suitable with bolt shank 9 diameter, and the diameter in the hole of outer expander 7 middle parts settings is greater than the diameter in the hole of interior expander 6 middle parts settings.
Jigging conveyer is mainly made up of cell body 1, balanced body 2, frame 3, Rocker arm 4, transmission component etc.When work, by the classical V-belt on belt pulley, transmission shaft is rotated by electrical motor, then making connecting rod promote balanced body 2 by decentralizing device moves, drive cell body 1 to do and the approximate simple harmonic oscillation of balanced body synchronous backward by balanced body 2 by Rocker arm 4 again, in the time that cell body vibration acceleration reaches a certain value, material is just made continuous sling movement along throughput direction in cell body, thereby material is moved forward, and realizes the object of carrying.In the time that balanced body and cell body are done the approximate simple harmonic oscillation of synchronous backward, by the absorbing sound absorption of mutual balance and bump rubber, rubber bar, substantially eliminate the vibration of frame, thereby made conveyer smooth running in the course of the work.For preventing coming off of rubber bar, installing anti-drop device 5 additional, thereby ensureing that rocking arm normally works.
Inside and outside expander 6,7 and mounting hole are free-running fit, and expander is installed in rotating shaft endoporus, then turn bolt shank 9, and 6,7 of inside and outside expanders relatively move, and realize the object that side set expands.At this moment inside and outside expander 6,7 and mounting hole are interference fit, and bolt shank 9 continues outwards to screw out, and inside and outside expander 6,7 is realized side set and expanded with shaking mounting hole, and friction force continues increase, and inside and outside expander 6,7 is fastened in mounting hole.Due to anticreep cover plate 8 being installed, both positions are limited to its installation site and unlikely deviate from or drop, reach slip-off preventing object.
