[0012] In order to make those skilled in the art better understand the technical scheme of the utility model, the preferred embodiment of the utility model is described below in combination with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, and not for limiting the utility model patent claim. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0013] The utility model is further illustrated below in combination with the drawings and preferred embodiments.
[0014] Embodiment 1
[0015] Referring to Figure 1 And Figure 2 It is shown that the concrete mixing device related to the embodiment includes a rack 1, the rack 1 is provided with a stirring container 2 in the shape of rotation, the container mouth of the stirring container 2 faces upwards, the stirring container 2 is rotationally connected with a radial circle 3 outside, the radial circle 3 is provided with a bent arm body 4, the bent arm body 4 includes a bent arm lower section 41 extending along the axial direction of the stirring container, the bent arm lower section 41 is connected with a bent arm upper section 42 extending into the interior of the stirring container, the bent arm upper section 42 is rotationally connected with a shaft 5, one end of the shaft 5 is provided with a stirring paddle 6 following the motion and extending into the interior of the stirring container, the other end is transmissionally connected with a first power assembly 7 for controlling rotation, the first power assembly 7 is arranged on the bent arm upper section 42, the radial circle 3 is provided with an external gear ring 8, the external gear ring 8 is engaged with a gear 9, the gear 9 is transmissionally connected with a second power assembly 10 for controlling rotation, the second power assembly 10 is arranged on the rack 1, the stirring paddle 6 is arranged eccentrically in the interior of the stirring container 2.
[0016] Furthermore, the stirring paddle 6 includes a first rod 61 and a second rod 62 extending along the axial direction of the stirring container 2. A third rod 63 near the top and a fourth rod 64 near the bottom are connected between the second rod 62 and the first rod 61. A fifth rod 65 is also connected between the first rod 61 and the second rod 62 and disposed between the third rod 63 and the fourth rod 64.
[0017] Furthermore, the stirring container 2 is provided with a circular guide rail 11, and the spoke 3 is slidably connected to the circular guide rail 11.
[0018] Furthermore, both the first powertrain 7 and the second powertrain 10 include a motor and a speed reducer.
[0019] Furthermore, the upper section 41 of the curved arm is located inside the mixing container 2 near the container opening.
[0020] In this embodiment, the second power assembly 10 controls the agitator 6 to rotate, and the first power assembly 7 controls the agitator 6 to circumferentially rotate. When the first power assembly 7 is in operation, the gear 9 rotates, which is transmitted through the external gear ring 8. The spoke ring 3 rotates around the axis of the mixing container 2 outside the mixing container 2, driving the connected curved arm body 4 to follow suit.
