[0015] Preferably, stirring blades are fixedly provided on both sides of the rod wall of the top rod.

[0016] Compared with the prior art, the utility model provides a concrete mixing arm with a vibration function, which has the following beneficial effects:

[0017] 1. The concrete mixing arm with vibration function is provided with a movable sleeve, a fixed block, a connecting rod and a push rod. During the rotation of the mixing shaft, the push rod is driven to rotate together, so that the lower end of the push rod is in contact with the lifting mechanism at the bottom. At this time, multiple movable sleeves and the mixing arms on the movable sleeves can be pushed upward. When the lower end of the push rod is not lifted upward, the movable sleeve and the mixing arm fall due to gravity, so that the mixing arm can have the function of vibrating up and down, which can not only prevent the outer wall of the mixing arm from sticking to the concrete raw materials, but also improve the mixing quality of the concrete raw materials.

[0018] 2. The concrete mixing arm with vibration function is provided with a lifting ring and a lifting protrusion.

[0019] 3. The concrete mixing arm with vibration function is provided with a fixed ring, a spring and a movable ring. When the multiple movable sleeves move upward, the top movable sleeve presses the movable ring upward, and at the same time, the spring is squeezed between the movable ring and the fixed ring, so that the multiple movable sleeves have a tendency to move downward elastically, and the multiple mixing arms can be quickly reset downward.

[0020] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model has the function of up and down vibration, which can not only prevent the outer wall of the stirring arm from sticking to the concrete raw materials, but also improve the mixing quality of the concrete raw materials.
