[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 In this embodiment of the present invention, a mixing device for municipal construction includes a mixing tank 1. A downwardly protruding limiting post 4 is integrally formed at the center of the bottom end of the mixing tank 1. An outwardly protruding fixing shaft 12 is integrally formed at both ends of the outer periphery of the mixing tank 1. A fixing rod 5 is rotatably installed on the outer periphery of the fixing shaft 12. A base 6 is fixedly installed at the bottom end of the fixing rod 5. A limiting mechanism extending into the interior of the mixing tank 1 and penetrating to the top of the mixing tank 1 is installed on the outer side of the base 6. The limiting mechanism is used to limit the limiting post 4 in a vertical state. A driving mechanism connected to a fixing shaft 12 is installed on the outer side of one fixing rod 5. A mounting frame 2 is fixedly installed on the upper outer periphery of the mixing tank 1. An agitator 3 extending into the interior of the mixing tank 1 is installed on the top plate of the mounting frame 2.

[0020] In this embodiment: First, when the mixing tank 1 is in a vertical position, all the raw materials for mortar are added to the mixing tank 1. Then, the agitator 3 is started, and the agitator 3 fully mixes the added raw materials. After the mixing is completed, the limiting mechanism is released from the limiting column 4, and then the driving mechanism is started. The driving mechanism drives the mixing tank 1 to rotate. During the rotation, the mixing tank 1 rotates from a vertical position to a horizontal position. During the rotation, the mortar that has been mixed in the mixing tank 1 is poured out, and a container is used to collect the poured mortar.

[0021] Please refer to this carefully. Figure 1 and Figure 2 The drive mechanism includes a worm gear 14 mounted on the outside of a fixed rod 5 via a bracket. The worm gear 14 is rotatably connected to the bracket via a rotating shaft and bearings. A forward and reverse motor 15 is mounted on the outside of the bracket. The output shaft end of the forward and reverse motor 15 is fixedly connected to the center of one end of the worm gear 14. A worm wheel 13 meshes with the outer periphery of the worm gear 14. The worm wheel 13 is fixedly mounted on one end of a fixed shaft 12.

[0022] In this embodiment: after the limiting mechanism is released, the forward and reverse motor 15 drives the worm gear 14 to rotate, and the rotating worm gear 14 drives the worm wheel 13 to rotate. The worm wheel 13 drives the mixing tank 1 to rotate through the fixed shaft 12 connected to it. The fixed shaft 12 and the fixed rod 5 are rotatably connected through the bearing, so as to realize the pouring of the mixed mortar.

[0023] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4 The limiting mechanism includes a fixed limiting plate 7 integrally formed with the top of the base 6 and a sliding limiting plate 8 that is slidably connected to the base 6. The docking points of the base 6 and the sliding limiting plate 8 are formed with docking grooves. The inner wall of the circle formed by the two docking grooves matches the outer wall of the limiting post 4. The limiting mechanism also includes a sliding plate 17 integrally formed with the bottom of the sliding limiting plate 8. The base 6 has an internal receiving groove 16 for the sliding plate 17 to slide up and down. A return spring 18 is fixedly installed between the bottom of the sliding plate 17 and the bottom of the inner wall of the receiving groove 16. A connecting rod 10 protruding outward is welded to the outer wall of the sliding limiting plate 8. The base 6 has an internal sliding groove 9 for the connecting rod 10 to slide. A foot pedal 11 is fixedly installed at the end of the connecting rod 10 located outside the base 6.

[0024] In this embodiment: Before starting the drive mechanism, the foot pedal 11 is stepped on. The foot pedal 11 is forcefully driven to slide the connecting rod 10 downward along the sliding groove 9. The connecting rod 10 then drives the sliding limit plate 8 and the sliding plate 17 connected to it to move downward. The sliding plate 17 moves along the receiving groove 16. At this time, the return spring 18 is compressed until the sliding limit plate 8 and the limit post 4 are misaligned. At this time, the limiting mechanism no longer restricts the limit post 4, so the mixing tank 1 can rotate.

[0025] After the mortar is poured, when the mixing tank 1 is driven to rotate to a vertical position by the drive mechanism, the limiting column 4 comes into contact with the inner wall of the fixed limiting plate 7. At this time, the mixing tank 1 can no longer continue to the vertical position, thus realizing the precise reset of the mixing tank 1.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
