Stirring knife for stabilized soil mixing plant

Abstract

The invention discloses a stirring knife for a stabilized soil mixing plant. The stirring knife comprises a knife blade body which is provided with mounting holes fixed with a stirring arm; the stirring knife also comprises bosses arranged on the knife blade body, and a knife blade end arranged at one side of the knife blade body; each boss is located at one side of one mounting hole; the knife blade end is connected with the knife blade body in a circular arc transition manner; the knife blade end is provided with a jagged concave-convex cavity which comprises convex parts and concave parts that are alternately arranged; and a cutting angle beta is formed between the knife blade end and a horizontal plane. The stirring knife provided by the invention has simple structure; the surface of the knife blade end is designed to have a cutting angle with similar to a cutting tool and the jagged concave-convex cavity is arranged at the same time, so a discharge groove is formed during blending, and thus, the direct collision force between the surface of the knife blade end and a material is retarded during stirring, vibration and noise during stirring operation are reduced, and energy consumption is decreased.

Description

technical field [0001] The invention relates to a component used in a mixer of stabilized soil mixing equipment, in particular to a mixing knife for stabilized soil mixing equipment. Background technique [0002] The mixer is the core component of the stabilized soil plant mixing equipment, and it undertakes the function of mixing various stones, sand, stone powder and other aggregates for the stabilized soil plant mixing equipment. The main part of the mixer includes the main body of the mixer, the bearing seat, the shaft end plate, the mixing shaft, the mixing knife, the bearing, the motor, the reducer, the gear and other parts. Most of the mixing knives are made of metal, and the stabilized soil factory mixing Equipment mixing knife mixing is similar to the principle of tool cutting, so the mixing knife must also have appropriate geometric parameters such as cutting angle. [0003] The end face of the existing mixing knife has no inclination angle, no jagged concave-conv...

AI Technical Summary

Problems solved by technology

[0003] The end face of the existing mixing knife has no inclination angle, no jagged concave-convex cavity, and due to the collision between the stirring and the material, the impact force on the end face of the blade during stirring is large, and the material is pressed harder and harder, and the blade wears seriously. Abnormal vibration and noise, the stirring efficiency is greatly reduced, which brings great problems to the use
