Embodiment Construction

[0027] Examples see Figure 1-5 As shown, this twin-shaft concrete mixer includes a barrel 4, a stirring shaft 3 inside the barrel, and a stirring blade connected to the stirring shaft. The stirring shaft 3 is connected to the rotary mechanism of the main motor reducer. Unloading container 7. Two stirring shafts 3 are arranged in parallel in the barrel 4, the installation forms of the stirring blades on the two stirring shafts are exactly the same, and the installation directions are opposite; The cross section can be a regular hexagonal prism. The middle part of the stirring shaft 3 is connected with four middle stirring blades 1 , and the two ends of the stirring shaft are connected with two end stirring blades 2 . The knife faces of the middle stirring blade 1 and the end stirring blade 2 form an angle of 45° with the axis of the stirring shaft, and the handles of two adjacent stirring blades differ by 120° along the circumferential direction of the stirring shaft. There...

Abstract

A double-horizontal axle concrete-mixer comprises a material barrel, mixing shafts in the material barrel and mixing blades which are connected with the mixing shaft. The mixing shaft is connected with the revolving mechanism of speed reducer of main motor. Two mixing shafts are installed in parallel in the material barrel. The mixing blades on two mixing shafts have same installation form and opposite installation directions. The mixing blades are distributed with a spiral form along the axial directions of mixing shafts. The middle part of mixing shaft is connected with middle mixing blades. Two ends of mixing shafts are connected with end mixing blades. The blade surface of middle mixing blade has a sickle shape. The blade surface of end mixing blade has a kitchen knife shape. The end of knife handle is provided with screw thread. The knife handle traverses the radial preserved hole passage of mixing shaft. The screw thread at end of knife handle is connected with the nut. The double-horizontal axle concrete-mixer of the invention has advantages of stronger mixing capability, simpler structure of mixing shaft, and easy changing and regulation of mixing blade.

Description

technical field [0001] The invention relates to a concrete mixer. Background technique [0002] The stirring device of the existing single-horizontal shaft concrete test mixer either adopts a spiral stirring blade, or adopts a stirring shovel fixed on the stirring arm. When the spiral stirring blade is used, the contact area between the stirring blade and the material to be mixed is small during the stirring process, the force along the circumferential direction of the barrel and the axial direction of the stirring shaft is small, the stirring time is long, and the stirring efficiency is poor. When using a mixing shovel fixed to the mixing arm, on the one hand, it is necessary to consider the connection between the mixing arm, the stirring shaft and the mixing shovel, and the structure is complex; on the other hand, the area of ​​the mixing shovel is large, the resistance is relatively large when the material is mixed, and the energy consumption of the equipment is high. , ...
