Abstract

A high-speed asphalt agitator without jam has an agitating tank with antiwear liner on its arc bottom, and two agitating axle with blades. It features that the rotational center of said agitating axleand blades and the circular center of said arc bottom are eccentric, so the distance between the tracing of blades and the antiwear liner is gradually increased, resulting in no jam.

Description

technical field

[0001] The invention belongs to road construction machinery, and relates to the structure of a paddle-type mixing cylinder of asphalt mixing equipment, in particular to an anti-wedge extrusion mixing cylinder. Background technique

[0002] Paddle mixing tank is the main device in the preparation process of asphalt mixture mixing equipment. In the mixing tank, the gravel material, mineral powder and asphalt weighed according to a certain mixing ratio are evenly mixed into the required finished asphalt concrete mixture. The paddle type mixing cylinder mainly includes a cylinder body and a pair of stirring shafts installed side by side in the cylinder body. The paddles for stirring are installed on the stirring shafts, and the arc-shaped bottom surface of the cylinder body is provided with a wear-resistant liner. When the mixing tank is working, the paddles buried in the bottom of the mixing tank in the mixture make the mixture move longitudinally and laterally...

Embodiment Construction

[0011] Such as image 3 , Figure 4 As shown, a stirring shaft 2 is installed in the cylinder body 1 of the anti-wedge extrusion high-speed mixing cylinder, and a paddle 3 is installed on the stirring shaft. Wear-resistant liners are distributed on the arc-shaped bottom surface 4 of the cylinder body, and the stirring shaft and the paddle There is an eccentric distance between the center of rotation of the blade and the center of the arc on the bottom surface of the cylinder, so that the distance between the running track of the end of the blade and the wear-resistant liner increases gradually in the direction of the blade. Such as Figure 4 As shown, the eccentric distance may include a lateral eccentricity x and a vertical eccentricity y.
