Mixing mechanism and self-compacting concrete mixer for rail transit precast slab rail structure

Abstract

The invention relates to a mixing mechanism and a self-compacting concrete mixer for a rail transit precast slab rail structure. The mixing mechanism is used for being arranged in a hopper in a rotating mode so as to mix self-compacting concrete in the hopper. The mixing mechanism comprises a shaft sleeve and multiple blade assemblies, the shaft sleeve is used for sleeving a driving rotating shaftand is in transmission connection with the driving rotating shaft, the multiple blade assemblies are arranged in the circumferential direction of the shaft sleeve at intervals, each blade assembly comprises a transverse mixing part and a vertical mixing part, one ends of the transverse mixing parts are arranged on the shaft sleeve, the other ends of the transverse mixing parts are connected to one ends of the vertical mixing parts, an included angle is formed between the lengthwise direction of each vertical mixing part and the lengthwise direction of the corresponding transverse mixing part,and the sides, deviating from the vertical mixing parts, of the transverse mixing parts are used for making contact with the bottom wall of the hopper in a sliding mode. According to the mixing mechanism and the self-compacting concrete mixer for the rail transit precast slab rail structure, due to the arrangement of the mixing mechanism, the mixing effect of the self-compacting concrete mixer for the rail transit precast slab rail structure is better.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a mixing mechanism and a self-compacting concrete mixer for rail transit prefabricated slab track structure. Background technique [0002] Cement mortar mixer, as a kind of construction equipment, is mainly used for mixing cement, sandstone, various dry powder mortar and other building materials. It is a mixing mechanism with blades that rotates in a cylinder or tank to mix various raw materials. Stir to combine to make a mixture or machine to the desired consistency. [0003] In order to reduce the resistance in the stirring process, the blades in the traditional stirring mechanism are mostly relatively small. However, such a stirring mechanism composed of relatively small blades usually has the problem of poor stirring effect. Contents of the invention [0004] Based on this, it is necessary to provide a mixing mechanism with a better mixing effect a...
