Problems solved by technology

Currently 1m 3 The vibrating mixer has been used in actual production, but its structure is complicated, and two motors are used to complete the drive and vibration. During the stirring process, the vibration frequency is generated by the rotation of the eccentric block on the shaft, and the frequency is fixed.
Moreover, the vibration transmitted to the mixing drum during the mixing process is too large
During the mixing process, the vibration force is too large and the vibration noise is too large. Large-scale vibrating mixers have not been used in practice.

Abstract

The invention relates to a small cement concrete oscillation mixer. A mixing shaft penetrating through a mixing drum is arranged in the mixing drum, and the two ends of the mixing shaft are nested in oscillators; the oscillators are nested in the side wall of the mixing drum, and one end of the mixing shaft is connected with a motor through a steel wire soft shaft; the two ends of the steel wire soft shaft are fixedly provided with couplings, and a plurality of mixing blades are fixedly arranged on the mixing shaft. The two ends of the mixing shaft are provided with the oscillators, so that the device changes with a certain frequency and a certain amplitude band, and the frequency and the amplitude constantly change; the mixing shaft slightly swings left and right due to uneven force of the blades, and the noise is reduced; a mixed material is evenly mixed, concrete is fully and quickly mixed and the content of gas of the concrete is increased, and the quickly mixed material is evenly mixed. The motor is used, so that energy is saved. The device is suitable for large-area popularization and use.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a small cement concrete vibrating mixer. Background technique [0002] Cement concrete is widely used in construction engineering, and some indicators such as quality uniformity and air content have high requirements. Currently 1m 3 The vibrating mixer has been used in actual production, but its structure is complicated, and two motors are used to complete the drive and vibration. During the stirring process, the vibration frequency is generated by the rotation of the eccentric block on the shaft, and the frequency is fixed. Moreover, the vibration transmitted to the mixing drum during the stirring process is too large. During the mixing process, the vibration force is too large and the vibration noise is too large. Large-scale vibrating mixers have not been used in practice. Contents of the invention [0003] The object of the present invention is ...
