Vibration mechanism of vibration stirrer

Abstract

The invention discloses a vibration mechanism of a vibration stirrer. The vibration mechanism comprises a non-power end supporting shaft, a power end supporting shaft and a stirring shaft; a vibrationmotor is fixedly arranged in the stirring shaft; one end of the stirring shaft is in power connection with the non-power end supporting shaft through an elastic coupling device; the other end of thestirring shaft is in power connection with the power end supporting shaft through another elastic coupling device; each elastic coupling device comprises an outer sleeve and an inner sleeve in the outer sleeve; a plurality of radially inward protruding inner transmission teeth are annularly distributed on the inner wall surface of each outer sleeve; a plurality of radially outward protruding outertransmission teeth are annularly distributed on the outer wall surface of each inner sleeve; the inner transmission teeth are not in contact with the inner sleeves and the outer transmission teeth, and the outer transmission teeth are not in contact with the outer sleeves and the inner transmission teeth, so that the inner transmission teeth and the outer transmission teeth form a space meshing relationship; and each outer sleeve and the corresponding inner sleeve are connected into a whole through an elastic connecting body formed by firstly hot melting and then solidifying elastic materialsfilling a gap between the outer sleeve and the inner sleeve. The vibration mechanism of the vibration stirrer can carry out full-shaft vibration stirring, and the stirring effect is good.

Description

technical field [0001] The invention relates to a vibration mixer, in particular to a vibration mechanism of the vibration mixer. Background technique [0002] Vibrating mixers are widely used for mixing materials in road construction and construction fields. The vibration mechanism of the existing vibrating mixer includes a stirring shaft and a transmission shaft. The transmission shaft is connected with one end of the stirring shaft through a floating bearing. The transmission shaft and the stirring shaft are arranged eccentrically. Vibrate. The amplitude of the stirring shaft is the largest at the connection end with the transmission shaft, then gradually decreases, and the amplitude drops to zero at the end of the stirring shaft far away from the transmission shaft, so the vibration stirring effect is not good, and the transmission shaft needs to support the stirring shaft during high-speed rotation, resulting in The wear and tear of the bearings that cooperate with th...

Problems solved by technology

The amplitude of the stirring shaft is the largest at the connection end with the transmission shaft, then gradually decreases, and the amplitude drops to zero at the end of the stirring shaft far away from the transmission shaft, so the vibration and stirring effect is not good, and the transmission shaft needs to support the stirring shaft during high-speed rotation, resulting in The wear of the bearings that cooperate with the transmission shaft increases rapidly, and the transmission shaft needs to be driven by the drive motor through the transmission chain, which not only results in complicated connection structures but also increases energy consumption
