Furthermore, the included angle between the anti-vortex stirring paddle and the driven stirring shaft is 60-90 degrees.

Further, the vortex-proof stirring paddle is perpendicular to the driven stirring shaft.

Furthermore, the anti-vortex stirring paddles on the same driven stirring shaft are arranged in a mutually staggered mode along the vertical direction.

Furthermore, a plurality of the vertical direction arrangement of the vortex-proof stirring paddles is two rows, the two rows of the vortex-proof stirring paddles are arranged in a staggered mode in the vertical direction, and each row of the vortex-proof stirring paddles is connected with one vertically arranged vertical stirring paddle.

Furthermore, the upper part of the driving stirring shaft is also provided with a plurality of auxiliary stirring paddles which are arranged in a mutually staggered mode.

The utility model discloses a concrete mixer of stirring's beneficial effect is:

1. through driving two driven gear rotations at the driving gear, and then drive driven (mixing) shaft and rotate, make the rotation direction of initiative (mixing) shaft opposite with driven (mixing) shaft's rotation direction to disturb because the vortex that the initiative (mixing) shaft stirred always and caused, thereby faster stir and the stirring.

2. The stirring shaft is provided with a plurality of stirring paddles which are arranged in a staggered mode, eddy currents are scattered in different levels and different heights, concrete is mixed, and mixing is accelerated.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic structural diagram of embodiment 1 of the present invention;

FIG. 2 is a schematic structural diagram of embodiment 2 of the present invention;

FIG. 3 is a schematic structural diagram of embodiment 3 of the present invention;

fig. 4 is a schematic structural diagram of embodiment 4 of the present invention.

In the figure, the stirring device comprises a stirring drum 1, a stirring cylinder 2, a mounting bracket 3, a stirring motor 4, a driving stirring shaft 5, a driving gear 6, a driven gear 7, a fixed shaft 8, a driven stirring shaft 9, an anti-vortex stirring paddle 10, a main stirring paddle 11, a vertical stirring paddle 12 and an auxiliary stirring paddle.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Example 1

The concrete mixer of fig. 1 includes a mixing drum 1, a mounting bracket 2 fixed on the upper end of the mixing drum 1, a mixing motor 3 mounted on the mounting bracket 2, a driving mixing shaft 4 coaxially connected with the mixing motor 3, a driving gear 5 fixedly mounted on the upper portion of the driving mixing shaft 4, two fixed shafts 7 symmetrically arranged on both sides of the driving mixing shaft 4 and fixed on the mounting bracket 2, a driven gear 6 mounted on the fixed shaft 7 through a bearing, and a driven mixing shaft 8 fixedly mounted on the lower side of the driven gear 6; the driven gear 6 is matched and meshed with the driving gear 5; the bottom end of the driving stirring shaft 4 is provided with a main stirring paddle 10, and the main stirring paddle 10 is generally a spiral stirring paddle; the driven stirring shaft 8 is provided with a plurality of anti-vortex stirring paddles 9. The vortex-proof stirring paddle 9 is a straight blade paddle, and the included angle between the general vortex-proof stirring paddle 9 and the driven stirring shaft 8 is 60-90 degrees. In the embodiment, the vortex-preventing stirring paddle 9 is perpendicular to the driven stirring shaft 8. The vortex-proof stirring paddles 9 on the same driven stirring shaft 8 are arranged in a mutually staggered mode along the vertical direction.
