Abstract
The present invention is one kind of real-time adjustable eccentric vibrator. The improved eccentric vibrator has two rotating shafts, each of which has two sliding blocks; and two herringbone racks, each of which hinges two sliding blocks in the same rotating shaft to the eccentric block. The relative moving of two sliding blocks in the same rotating shaft makes the height of the herringbone rack, so that the excitation force the eccentric block generates changes correspondingly. The excitation forces the eccentric blocks separately on two rotating shafts are controlled with the lead screw connected integrally, and one rotating device is set to one end of the lead screw for regulating the excitation force of the eccentric vibrator. The present invention is used for vibrating sieve, vibrating road roller, vibrating crusher, etc.
Description
Technical field
The present invention relates to a kind of exciting device, particularly a kind of eccentric vibrator of adjustable eccentric block exciting.
Background technology
Existing eccentric vibrator generally comprises two rotating shafts and is located at the eccentric block of two identical weight in the rotating shaft respectively, and by the synchromesh gear engaged transmission, the axial end of a rotating shaft wherein is provided with by motor-driven belt pulley between two rotating shafts.When belt pulley rotated under the motor effect, two rotating shafts were rotated under the effect of synchromesh gear like this, did the synchronous backward rotation thereby be located at two eccentric blocks in the rotating shaft, and then produced exciting.Adjusting exciting force method commonly used at present is by silver or the dress steel ball of pouring water in eccentric block, changes its exciting force with the quality that changes eccentric block; Also have by hydraulic system or frame for movement and change the centrifugal radius of eccentric block.The weak point of above-mentioned eccentric vibrator is that exciting force only just can be adjusted under the state of shutting down, and adjustment process is more loaded down with trivial details, can not realize adjusting in real time exciting force.
Summary of the invention
