DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides an embodiment: a concrete mixing device for construction engineering, comprising a mixing tank 1, a motor 2 is fixedly connected to the upper surface of the mixing tank 1, a fixing ring 3 is fixedly connected to the interior of the mixing tank 1, a first rotating shaft 4 is fixedly connected to the output end of the motor 2, and a first stirring rod 5 is fixedly connected to the outer surface of the first rotating shaft 4, so as to facilitate the mixing of concrete.

[0025] The top inner wall of the mixing tank 1 is fixedly connected with a hydraulic device 6, and the bottom end of the hydraulic device 6 is fixedly connected with a limit plate 7. The hydraulic device 6 can limit the limit plate 7 so that it cannot rotate, and will only drive the limit plate 7 and the limit column 8 to rise and fall, so as to drive the first gear 9 to engage with the third gear 14, or the second gear 10 to engage with the fourth gear 16. The lower surface of the limit plate 7 is fixedly connected with the limit column 8, and the interior of the limit column 8 is rotatably connected to the first rotating shaft 4. The outer surface of the limit column 8 is fixedly connected with the first gear 9, and the outer surface of the limit column 8 is fixedly connected with the second gear 10. The second gear 10 is smaller in size, and the first gear 9 is larger than the second gear 10.

[0026] A first limiting ring 11 is fixedly connected to the outer surface of the first rotating shaft 4, a connecting block 12 is fixedly connected to the outer surface of the first limiting ring 11, and a second limiting block 13 is fixedly connected to a side of the connecting block 12 away from the first limiting ring 11. The second limiting block 13 can limit the second rotating shafts 15 on both sides, and drive the second rotating shafts 15 to rotate around the first rotating shaft 4 as the axis.

[0027] The outer surface of the first gear 9 is meshedly connected with the third gear 14. The third gear 14 is provided with two groups and is located on both sides of the first gear 9. The rotation of the first gear 9 can drive the two third gears 14 to rotate. The first gear 9 is larger than the third gear 14, which will drive the third gear 14 to rotate faster, thereby accelerating the mixing speed of the concrete by the second rotating shaft 15 and the second stirring rod 17. The lower surface of the third gear 14 is fixedly connected with the second rotating shaft 15, and the outer surface of the second rotating shaft 15 is fixedly connected with the second stirring rod 17. The third gear 14 can drive the second rotating shaft 15 and the second stirring rod 17 to mix with the concrete. The fourth gear 16 is fixedly connected to the outer surface of the second rotating shaft 15 and is located at the lower side of the third gear 14. The fourth gear 16 is provided with two groups and is located on both sides of the second gear 10. The outer surface of the second rotating shaft 15 is rotatably connected to the second limit block 13, and the outer surface of the fourth gear 16 is meshed with the second gear 10. When the second gear 10 rotates, the fourth gear 16 can be driven to rotate, and the fourth gear 16 is larger than the second gear 10. The rotation of the second gear 10 will slow down the rotation speed of the fourth gear 16 itself, thereby slowing down the concrete mixing speed.

[0028] A sliding column 18 is fixedly connected inside the first rotating shaft 4, which is convenient for increasing the stability of the spring 20 when it is extended and retracted, and is also convenient for limiting the movable rod 19. The outer surface of the sliding column 18 is slidably connected to the movable rod 19, and the upper surface of the movable rod 19 is fixedly connected to the spring 20. The spring 20 is sleeved on the outer surface of the sliding column 18, which is convenient for providing buffering for the stirring work of the scraper 21 on the bottom of the mixing tank 1. The outer surface of the movable rod 19 is slidably connected to the first rotating shaft 4, and the lower surface of the movable rod 19 is fixedly connected to the scraper 21. The outer surface of the scraper 21 is rotatably connected to the mixing tank 1. The rotation of the scraper 21 can stir the concrete settled at the bottom of the mixing tank 1.

[0029] A feed port 22 is fixedly connected to the outer surface of the mixing tank 1 , a discharge port 23 is fixedly connected to the lower surface of the mixing tank 1 , a supporting leg 24 is provided at the bottom end of the mixing tank 1 , and the motor 2 is connected to an external power source.

[0030] When the embodiment of the present application is in use: when stirring, the motor 2 is started to drive the first rotating shaft 4 and the first stirring stick 5 to rotate. When the first rotating shaft 4 rotates, it will drive the first limiting ring 11, the connecting block 12, and the second limiting block 13 to rotate, thereby driving the third gear 14, the second rotating shaft 15, the fourth gear 16, and the second stirring stick 17 on both sides to rotate as a whole with the first rotating shaft 4 as the axis. When the third gear 14 rotates, it will mesh with the first gear 9, and the volume of the third gear 14 is smaller than the first gear 9, so that the rotation of the third gear 14 The speed is accelerated, driving the third gear 14, the second rotating shaft 15, and the second stirring rod 17 to stir the concrete. When the speed needs to be adjusted, the hydraulic device 6 is controlled to drive the limit plate 7, the limit column 8, the first gear 9, and the second gear 10 to descend, so that the second gear 10 is meshed with the fourth gear 16. The volume of the second gear 10 is smaller than that of the fourth gear 16. When the two are meshed, the speed of the fourth gear 16 will slow down, which increases the adjustability of the device. When the first rotating shaft 4 rotates, it will drive the scraper 21 at the bottom to rotate, so as to stir the concrete precipitated at the bottom.
