Technical Field

The invention belongs to the technical field of concrete mixer trucks, and particularly relates to a novel steel-ceramic composite mixing tool and a mixer.

Background

With the rapid development of the construction technology of the modern engineering construction site, a concrete pump truck is widely popularized and applied, and a stirrer is a machine which rotates a shaft with blades in a cylinder or a tank to stir and mix a plurality of raw materials to form a mixture or a proper consistency. Note that: the stirrer and the automatic feeder must be cleaned, especially in winter, so that the service life of the stirrer and the automatic feeder can be prolonged. The mixer is a mixer, and is commonly called a stirrer because the mixer generally functions to mix and stir various dry-mixed mortars.

Because the concrete mixing knife works like mixing gravel and cement fully and uniformly, the mixing knife generates friction with the gravel cement under the action of force, thereby generating abrasion.

At present, stirring knives of mixers all over the country adopt a manufacturing process of cast wear-resistant steel, and because material media are hard and particles are large, and mechanical movement is added, the stirring knives are easy to wear, one-time stirring knife replacement can be realized, the shutdown maintenance time is shortened, and the maintenance cost is increased.

In addition, the concrete is often agglomerated inside the existing mixer, which is difficult to treat and insufficient in mixing,

therefore, a pump truck stirring knife is urgently needed to solve the problems in the prior art.

Detailed Description

As used in the specification and in the claims, certain terms are used to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This specification and claims do not intend to distinguish between components that differ in name but not function. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.

The present application will be described in further detail below with reference to the accompanying drawings, but the present application is not limited thereto.

The first embodiment is as follows:

as shown in fig. 1, 2 and 3, the novel steel-ceramic composite stirring knife provided by the invention is characterized by comprising a connecting end 1, a blade 2 and a steel-ceramic composite tool bit 3 which are sequentially arranged from inside to outside, wherein the connecting end 1 is used for connecting the stirring knife to a stirring power device, the tail end of the blade 2 is connected with the steel-ceramic composite tool bit 3, the inner side surface of the steel-ceramic composite tool bit 3 in an L shape is tightly adhered to the blade 2, the tail end of the steel-ceramic composite tool bit 3 is an arc surface, the tail part of the outer side surface is tilted upwards to form a thickened part 4, and the thickened part 4 is in a tail shape.
