Description of drawings
Now the present invention is further elaborated in conjunction with the accompanying drawings:
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is one of relative position schematic diagram of vibrating shaft of the present invention and transmission system;
The specific embodiment
The present invention as shown in Figure 1, 2, comprise rotating cylinder 1, excitation power source 11, direction of excitation guiding mechanism 12 and retaining mechanism 14, rotating cylinder 1 is bearing on the vibrating wheels 2 by bearing 13, is provided with a pair of vibrating shaft 3,4 in the rotating cylinder 1, respectively is provided with one group of eccentric block 5,6 on the vibrating shaft 3,4; Vibrating shaft 3,4 is symmetrically distributed in the both sides of the axis of rotation O-O of rotating cylinder 1, can rotate relative to frame 22 wraparound shaft axis O-O together under rotating cylinder 1 drives; The left and right sides of vibrating shaft 3,4 is equipped with block bearing 8, vibrating shaft 3,4 links by transmission mechanism 7 and exciting power transmission shaft 9, excitation power source 11 links by shaft coupling 10 with exciting power transmission shaft 9, transmission mechanism 7 is provided with some driving members, for example be provided with 4 travelling gears 71,72,73,74, travelling gear 71,72 connects firmly respectively the axle head of vibrating shaft 3,4 (for example: connect firmly by the key connection); Exciting power passes to vibrating shaft 3,4 from excitation power source 11 by shaft coupling 10, exciting power transmission shaft 9, transmission mechanism 7, thereby the eccentric block 5,6 that drives on the vibrating shaft 3,4 is done with fast backward rotation; The end of rotating cylinder 1 also is provided with the retaining mechanism 14 of direction of excitation guiding mechanism 12 and rotating cylinder 1, when adjusting direction of excitation, rotating cylinder 1 rotates relative to frame 22 wraparound shaft axis O-O, the direction of excitation adjustment finishes, rotating cylinder 1 connects firmly by retaining mechanism 14 and frame 22 and is integral, direction of excitation guiding mechanism 12 is provided with motor 121 and power transmission shaft 122, motor 121 can be oscillating motor or other power source, its output and power transmission shaft 122 link, power transmission shaft 122 links with rotating cylinder 1, retaining mechanism 14 can surge or be electronic, and retaining mechanism 14 processes direction of excitation guiding mechanism 12 adjusted rotating cylinders 1 and frame 22 connect firmly and be integral.
When needs are adjusted direction of excitation, unclamp retaining mechanism 14 earlier, then under the effect of motor 121, drive of the axis of rotation O-O revolution of rotating cylinder 1 relative frame 22 by power transmission shaft 122, until the axes O of crossing vibrating shaft 3,4 around vibrating wheels 2
