Type is directed to disadvantages described above, connects three spur gear engaged transmissions using three straight-through axles during design, drives three groups of 120 ° of eccentric blocks
Rotate in opposite directions, produce exciting force, spur-geared advantage is to ensure eccentric block synchronous exciter, and exciting force is big, amplitude
Height, spur gear eccentric block structure makes the machine produce preferable straight reciprocating motion, realizes and is horizontally mounted, effectively reduces machine
Group height.The first straight-through axle of the machine drives the second straight-through axle and the 3rd straight by Hooks coupling universal coupling, belt pulley and motor connection
Axis is rotated, and gear compares 1 with motor speed:1, amplitude is up to 12~17mm, and vibration frequency is high, same sieving area, this practicality
The new three-shaft linkage block eccentric straight-line vibratory sieve can more domestic 1.5~2 times of like product raising.
