Abstract

A polygonal self-balancing type vibration exciter for concrete mixing equipment comprises one or two power devices and a polygonal vibration shaft; the one or two power devices are arranged at one ortwo ends of the polygonal vibration shaft and drive the polygonal vibration shaft to rotate; the polygonal vibration shaft is a polygonal shaft with the cross section having N smooth bulges, and N islarger than or equal to 1; and the smooth bulges are arranged spirally in the axial direction of the polygonal vibration shaft. The polygonal vibration shaft is a solid shaft or a hollow shaft, and the mass center of the polygonal vibration shaft is overlapped with the rotating center of the polygonal vibration shaft; the vibration excitation frequency of the vibration exciter is in linear positive correlation with the number N of the bulges and can be increased through increase of N or the rotating speed; the amplitude of the vibration excitation force can be adjusted through change of the bulge height, the material movement direction can be changed through change of the lead angle of the polygonal vibration shaft, and different vibration excitation effects can be realized. The vibrationexciter overcomes the defects of an eccentric vibration exciter, vibration mixing is realized under the combined action of the vibration exciter and the mixing equipment, and improvement of the mixingquality and efficiency is facilitated.

Description

Technical field [0001] The invention belongs to the technical field of vibration excitation equipment, and relates to a polygonal self-balancing type vibration exciter for concrete mixing equipment. Background technique [0002] Compared with traditional compulsory mixer, vibration mixing is more and more widely used in engineering applications because of its higher mixing efficiency and good mixing quality. Concrete vibration mixing is to mix the materials through the high frequency vibration generated by the vibration exciter and the mixing device to improve the mixing quality and efficiency. The exciter of the existing vibration mixer adopts the principle of eccentricity to generate vibration, the sealing effect of the shaft end is not good, and the bearing force is not good; it is very easy to heat under high-frequency vibration, and the bearing life is not long; at the same time, the force is complicated when stirring , The force of the vibrator is not easy to balance, the v...
