Vertical shaft planetary vibration type concrete mixer

Abstract

The invention discloses a vertical shaft planetary vibration type concrete mixer. Two mixing driving motors and a vibration driving motor are arranged on a mixing cylinder body, the mixing driving motors and the vibration driving motor are connected with a mixing device and a vibration exciter arranged in the mixing cylinder body through transmission devices respectively, the vibration driving motor is arranged between the two mixing driving motors, the mixing device rotates around the geometric center of the mixing cylinder body in the mixing cylinder body to mix concrete in a revolution rotation mode, the vibration exciter is in meshing connection with a sun wheel arranged on the vibration driving motor through a vibration exciter power transmission planetary wheel, strong vibration energy is transmitted into the concrete during revolution rotation, wear-resistant lining plates are arranged at the inner wall and the bottom of the mixing cylinder body, a discharging device is arrangedat the bottom of the mixing cylinder body, and the discharging device is connected with a hydraulic system and an electric system which are arranged outside the mixing cylinder body. The mixer is simple in structure, a gear ring required by a traditional planetary gear train does not need to be arranged, and a speed reduction mechanism is greatly simplified.

Description

technical field [0001] The invention belongs to the technical field of concrete mixers, in particular to a vertical shaft planetary vibration concrete mixer. Background technique [0002] Mixing is the most basic and necessary preparation method for preparing concrete. The mixer is a mechanical device for mixing, through which raw materials such as water, cement, sand and gravel aggregates and admixtures are evenly mixed into a mixture that meets the quality requirements. In the case of certain components and mix ratios, the performance of concrete directly depends on the mixer used to prepare concrete and its mixing process. Forced mixer is the most widely used concrete mixer type, the mechanical action provided by its mixing mechanism can make the materials quickly and uniformly disperse in the violent relative movement, which significantly improves the mixing efficiency and the performance of concrete. [0003] According to different mixing mechanisms, forced mixers can...

Problems solved by technology

The vibrating stirring method integrating the vibrating and stirring blades can increase the range of vibration and reduce the required vibration acceleration, but this structure is difficult to achieve the dynamic balance of the vibrating drive shaft

Because this integrated vibrator uses the stirring shaft and stirring blades as the vibrating part, several side blades and main blades with different structures and masses are fixed on the stirring shaft at different phase angles, which cannot guarantee the quality of the vibrator shell. It is distributed regularly along the axial and circumferential directions of the stirring shaft, so it is difficult to balance the inertial force and inertial moment generated by the eccentric masses of the vibration transmission shaft at the same time

This not only increases the requirements for vibration reduction, but also brings additional vibration to the transmission system and support system, increases noise, reduces reliability and service life
