The advantage of above-mentioned scheme lies in, because the cephalad portion has great thickness, consequently can promote the raw materials and roll at the in-process of stirring to obtain better stirring effect. Moreover, even if the head end portion has a large thickness, the cutting effect of the stirring blade on the raw material is not affected, and therefore the stirring effect is not deteriorated. Furthermore, the structure of the head end part is very simple, so that the production cost is not greatly increased, and the head end part can be conveniently applied to various mixers.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as being fixedly connected, integrally connected, or detachably connected; may be communication within two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art will understand the specific meaning of the above terms in the present invention in specific situations.

A preferred embodiment of the composite stirring blade is shown in fig. 1 to 5, and includes a stirring blade 2 and a head end portion 1, the upper side of the stirring blade 2 is an end portion 201, the lower side is a root portion 202, the head end portion 1 is fixedly disposed on the end portion 201, and the thickness of the head end portion 1 is greater than that of the stirring blade 2. When the stirring device works, the head end part 1 can play a role in pushing raw materials to roll, and the stirring knife 2 plays a role in cutting and pushing the raw materials, so that a better stirring effect can be obtained. As shown in fig. 1, the left side of the head end portion 1 is a force application side 11, and the right side is a back side 12, and during the stirring process, the force application side 11 applies a pushing force to the raw material to push the raw material to tumble. The force application side 11 is provided with a head end force application surface 111, the head end force application surface 111 is a plane, the width of the head end force application surface is smaller than the thickness of the head end part 1, a head end transition surface 112 is arranged between the head end force application surface 111 and the front side surface and the rear side surface of the head end part, and the head end transition surface 112 is also a plane or an arc surface. In this design, after the head end transition surface 111 presses the raw material, the raw material can roll along the head end transition surface 112, so that the head end portion 1 can effectively push the raw material to roll.

The rear side 12 is provided with a reinforcement rib 23, and the reinforcement rib 23 is used for enhancing the connection strength between the head end portion 1 and the stirring blade 2.
