Detailed Description

The embodiment of the utility model provides a sustainable concrete mixer, as shown in fig. 1-4, including motor 1, agitator frame 2, the setting is at 2 inside (mixing) shafts 3 of agitator frame, the setting is at the epaxial stirring rake 4 of (mixing)

shaft

3, 2 tops of agitator frame are opened, the opening 5 that supplies the material outflow is seted up to the bottom, expose in agitator frame 2 on the 3 top of (mixing) shaft, (mixing) shaft 3, its top is connected with gear 6, the axle center of gear 6 passes through the connecting rod and is connected with motor 1's output, gear 6's rotation can drive (mixing) shaft 3 and carry out eccentric rotation, stirring rake 4 is equipped with a plurality ofly, and along (mixing) shaft 3's vertical direction interval distribution, wherein same horizontal position sets up a stirring rake 4, orientation between the different stirring rakes 4 is different.

The stirring shaft 3 is provided with two stirring shafts, the gears 6 which are correspondingly connected are mutually meshed, and the two gears 6 rotate around the axes of the gears.

The cross section of the stirring frame 2 is oval, and the gear 6 is oval or any one of eccentric wheels.

The two stirring shafts 3 are positioned at the outer edge of the bottom of the gear 6, and the adjacent stirring paddles 4 on the two stirring shafts 3 have a height difference in the vertical direction, wherein the height difference ranges from 5 cm to 10cm, so that tangential acting force can be generated between the two stirring paddles.

The adjacent stirring paddles 4 are arranged in an up-and-down staggered manner, certain tangential acting force is generated between each other in the rotating process, and the phenomenon that the material generates centripetal force when doing uniform-speed circular motion can be effectively reduced, so that the full stirring of the material is facilitated.

The stirring shaft 3 is fixedly sleeved with a shaft sleeve 7, the inner side end of the stirring paddle 4 is hinged to one side of the shaft sleeve 7, the stirring paddle 4 is composed of two parts, namely a horizontal outer side part 8 and an inner side part 9 which is close to the stirring shaft 3 and is a broken line or any one of curves.

Through setting up to be eccentric pivoted (mixing) shaft 3 along with gear 6, the inboard is broken line or curvilinear, and the outside is the stirring rake 4 of level form, can effectively produce certain vortex to the material of 4 axle centers departments of stirring rake.

Wherein stirring rake 4 hinges all to be equipped with stopper 11 about the upper and lower of axle sleeve 7 department, and the range of restriction stirring rake 4 upper and lower pendulum that hangs down also can reduce simultaneously and lead to being in the phenomenon of circumference rotation always because of the rotation of (mixing) shaft 3.

If the turbulence blocks 10 are uniformly distributed on the inner wall of the stirring frame 2, the thickness of the turbulence block 10 at the horizontal position of the stirring frame 2 is smaller than that of the turbulence block 10 at the arc position of the stirring frame 2. When the materials do circular motion along with the stirring paddle 4 and collide with the flow disturbing block 10, a certain reverse resistance is generated, and the distance between the materials and the rotating shaft slightly changes along with the inner wall of the stirring frame 2. That is, the relatively insufficiently stirred material on the side away from the rotation axis can be moved toward the center side of the stirring shaft 3 by the flow disturbing block 10, and more sufficiently stirred.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
