Abstract

A disclosed efficient concrete stirrer comprises more than one stirring assembly, and the installing directions and the rotating directions of the adjacent stirring assemblies are opposite. One end of an outer spiral feeding shaft and one end of a spiral returning shaft in each stirring assembly are respectively connected with the active end and the passive end of a motor, and the other ends are connected with each other via a connection piece. The connection piece is an annular piece, the ends of the outer spiral feeding shafts and the ends of the spiral returning shafts are uniformly distributed on and connected with the annular piece; or an inner spiral feeding shaft is additionally disposed for connection of the active end and the passive end of the motor; or on the basis of additional arrangement of the inner spiral feeding shaft, the annular piece is dismantled into a first connection piece and a second connection piece, wherein the first connection piece is connected with the inner spiral feeding shaft and the outer spiral feeding shaft, and the second connection piece is connected with the inner spiral feeding shaft and the spiral returning shaft. The stirrer of the invention helps to solve the problem in the prior art that operation vibration is large because of large eccentricity, and has stable operation, increased material flow speed, severer stirring, fuller and more uniform mixing, and higher stirring efficiency.

Description

technical field [0001] The invention relates to a spiral mixing device, in particular to a mixing mechanism of a mixer used for mixing concrete. Background technique [0002] The current concrete mixer generally adopts a mixing mechanism running around a horizontal axis, and the mixing device usually adopts a double helical crankshaft structure. Please refer to the Chinese patent document ZL201020614615.0 "a double-helix concrete mixer" published on June 1, 2011. The mixer only consists of a set of stirring devices installed in the mixing drum. Feed crankshaft and inner and outer two return crankshafts are composed, and also include connecting shafts connecting inner and outer feed crankshafts and inner and outer return crankshafts. The device adopts a split connection structure in which the inner feed crankshaft is connected to the outer return crankshaft, and the outer feed crankshaft is connected to the inner return crankshaft. Such a connection structure is easy to pro...
