Drawings

Fig. 1 is the utility model discloses a road maintenance uses pitch agitating unit's schematic structure.

As shown in the figure: 1. the mixer comprises a mixing drum, 2, a feed hopper, 3, a mixing shaft, 4, a driving mechanism, 5, an arc-shaped pipe, 6, blades, 7, convex strips, 8, a driving motor, 9 and a speed reducer.

Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Example, see figure 1:

the utility model provides an asphalt mixing device for road maintenance, includes churn 1, feeder hopper 2, (mixing) shaft 3 and actuating mechanism 4, churn 1 is the tube structure, and both ends have the closure plate about it, and the discharge gate has been seted up to churn 1's bottom, and this discharge gate department closes through the switch door closure, fixed mounting has a plurality of sand grip 7 on churn 1's the inner wall, and the length direction of sand grip 7 is parallel with churn 1's center pin, and sand grip 7 is used for hindering the material to rotate along with the axle when mixing, makes the mixture of materials such as pitch more even, and sand grip 7 can adopt the semi-cylindrical structure, also can adopt prismatic structure, and is further, sand grip 7 is the triangular prism structure, and the welding of triangular prism is on churn 1's a section of thick bamboo.

Feeder hopper 2 fixed mounting be in the top of churn 1, and its discharge gate department extends out two at least arc pipes 5, and arc pipe 5 is four in the drawing, arc pipe 5 communicates around the top of churn 1, the feed inlet of feeder hopper 2 up, and materials such as pitch loop through feeder hopper 2, in entering churn 1 behind the arc pipe 5, and through arc pipe 5, can make in pitch and the more dispersed entering into churn 1 of other materials, guarantee the homogeneous mixing, wherein, for avoiding blocking, further, the diameter of arc pipe 5 via feeder hopper 2 moves towards churn 1 linear increase, smooth and easy passing through of materials such as pitch can be guaranteed to this kind of structure.

The stirring shaft 3 is rotatably installed in the stirring cylinder 1, a plurality of blades 6 are fixedly installed on the outer circumferential surface of the stirring shaft 3 along the axial direction of the stirring shaft, a certain space is formed between each blade 6 and the wall of the stirring cylinder 1, so that mixed materials can fall into the bottom of the stirring cylinder 1 from the space, the blades 6 are not perpendicular to the axial direction of the stirring shaft 3, the central shaft of the stirring shaft 3 is located on the central shaft of the stirring cylinder 1 and is installed in the stirring cylinder 1 through a bearing, the included angle between each blade 6 and the central shaft of the stirring shaft 3 is 45 degrees, one surface of each blade 6 faces obliquely upward, the other surface of each blade 6 faces obliquely downward, the surface facing obliquely downward faces the rotating direction of the stirring shaft 3, the stirring shaft 3 rotates to drive the blades 6 on the stirring shaft to rotate around the central shaft of the stirring shaft 3, so that the materials close to the stirring shaft 3, meanwhile, the blades 6 can push the material to integrally rotate so that the convex strips 7 can play a role.
