Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1, as shown in Figure 1, demonstration apparatus of vibration transmission machine mechanism is made up of vibrating bunker, sensor II and controller III;
Vibrating bunker is made up of hopper 6, hopper seat 9, spring 2, the quiet iron 3 of electromagnet, moving iron 4 and base 5.Spring 2 is fixed on the base 5 by contiguous block, and the other end is installed in the bottom of hopper seat 9, and contiguous block is the mechanism of an adjustable angle, can adjust in the certain angle scope; Base 5 is provided with protractor 8 simultaneously, can read the inclination angle number of degrees of spring.The quiet iron 3 of electromagnet is fixed on the base 5, and moving iron 4 is installed in the bottom of hopper seat 9, and moving iron 3 is relative with quiet iron 4 positions; The quiet iron 3 of electromagnet is fixed on the base 5 by a regulating device, it can the move left and right certain distance, and can regulate a segment distance up and down respectively, this regulating device in the vertical direction adopts screw-nut body, adopt U type groove (during installation can move left and right) on the horizontal direction, just to regulate once the gap of moving iron and quiet iron at spring inclination angle of every adjusting, can make electromagnet reach best operating condition.As shown in Figure 2, hopper 6 one ends are fixed by bolts to an end of hopper seat 9, do a U type groove in the middle of hopper seat 9, make hopper do the low-angle rotation around an end of hopper seat, when regulating the inclination angle of hopper 6, tighten with bolt again, hopper 6 and hopper seat 9 are become one.Index dial 7 is installed, so that read the inclination angle number of degrees of hopper 6 on the hopper base.Base 5 is parallel to each other with hopper seat 9;
