Relaxation sieve lever transmission system

Abstract

The invention discloses a relaxation sieve lever transmission system which comprises a first sieve machine outer sieve box, a second sieve machine outer sieve box, a sieve piece, a first push-pull spring seat and a second push-pull spring seat. The first push-pull spring seat and the second push-pull spring seat are connected with an inner sieve box; a left supporting plate and a right supporting plate are arranged on the left and right sides of the inner sieve box correspondingly; a long shaft of a first lever and a long shaft of a second lever are connected with a first eccentric sleeve and a second eccentric sleeve correspondingly, wherein a first driven shaft and a second driven shaft are sleeved with the first eccentric sleeve and the second eccentric sleeve correspondingly; the first driven shaft is connected with a first driven bevel gear and a first flywheel, and the second driven shaft is connected with a second driven bevel gear and a second flywheel; and the first driven bevel gear and the second driven bevel gear are connected with a first active bevel gear and a second active bevel gear which are fixed on an active shaft correspondingly in an engaged mode. The mutual movement of the sieve machine inner sieve box and the sieve machine outer sieve boxes is completed through the levers, the efficiency of force conduction is improved, equipment internal force is reduced, the driving torque is reduced, equipment power consumption is reduced, and the purchasing cost of production enterprises is reduced.

Description

technical field [0001] The invention relates to the technical field of relaxation screens, in particular to a lever transmission system of a relaxation screen. Background technique [0002] There are two types of transmission systems for the relaxation screen: the exciter drive system and the eccentric shaft drive system; among them, the vibration exciter drive system of the relaxation screen drives the main screen box to vibrate through the circular vibration of the exciter; further connection with the main screen The screen mesh between the box and the floating screen frame drives the floating screen frame to vibrate circularly, and the screen mesh does a relaxation movement at the same time; compared with the eccentric shaft drive system, the vibration exciter drive system is characterized by a single drive, as shown in the attached figure 1 The eccentric shaft drive system of the relaxation screen drives the inner and outer screen boxes to make opposite linear motions th...

AI Technical Summary

Problems solved by technology

However, because the exciter-driven screen machine is directly driven by the vibrator, the drive system needs to be very large, and the motor and bearing design need to be anti-seismic, which will increase the cost; the screen machine driven by the eccentric shaft is due to the Direct drive, so the main shaft needs to be relatively large, and the matching bearing also needs to be designed relatively large, and the cost will be high. In addition, this model is mostly imported equipment, so it has the disadvantage of being expensive
