In the prior art, usually a pouring chamber and a mixing chamber are arranged at the upper end of the chassis, and a mixing mechanism is arranged inside the mixing chamber to mix and stir the concrete. However, in this way, the mixing mechanism is a one-way mixing, which cannot meet the requirement of simultaneously mixing the concrete in both forward and reverse directions, and may lead to uneven mixing of the concrete, resulting in slurry stratification in the concrete or insufficient mixing of solid particles, affecting the quality of the concrete.

[0003] For example, the utility model with the publication number CN219710273U discloses a concrete pouring equipment for the construction of a water conservancy dam project. In the technical solution of this patent, a pouring chamber is assembled at the bottom end of the mixing chamber, and both the mixing chamber and the pouring chamber are fixedly installed at the upper end of the chassis. The bottom end of the pouring chamber is sleeved with a pouring port extending below the chassis, and a mixing mechanism is assembled in the mixing chamber to stir the concrete. However, in this way, the mixing mechanism is a one-way mixing, which cannot meet the requirement of simultaneously mixing the concrete in both forward and reverse directions. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a concrete pouring equipment for construction, which can not only achieve stable flow during the concrete pouring process by setting an output impeller, but also can stir the concrete in both forward and reverse directions by setting a first stirring shaft and a second stirring shaft, so as to more effectively make each component of the concrete fully mixed, reduce the stirring dead angle, make the concrete mixture more uniform, and is beneficial to improving the overall quality of the concrete.

However, the protection scope of the present utility model is not limited to the following embodiments. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0023] As shown in Figure 1 、 2 、3, a concrete pouring device for construction includes a chassis 101. A pouring box 102 is arranged at the upper end of the chassis 101. A mixing box 103 is arranged at the upper end of the pouring box 102. A pouring port 108 extending below the chassis 101 is arranged at the bottom end of the pouring box 102. A first stirring mechanism is arranged inside the pouring box 102. A second stirring mechanism is arranged inside the mixing box 103. A feeding port 104 for feeding is arranged at the upper end of the mixing box 103.

[0024] As shown in Figure 1 、 2As shown in the figure, the first stirring mechanism includes a stirring column 105 rotatably arranged in the middle of the pouring box 102. An output impeller 106 is arranged on the outer arc surface of the stirring column 105. A first motor 107 is arranged on the outer side surface of the pouring box 102. The output end of the first motor 107 is connected to the stirring column 105 through a coupling. Starting the first motor 107 can make the stirring column 105 rotate, and then make the output impeller 106 rotate. By precisely controlling the rotation speed and working state of the output impeller 106, the flow rate stability during the concrete pouring process can be achieved, which helps to reduce problems such as faults and cold joints during the construction process.

[0025] As Figure 1 , 3 shown in the figure, the second stirring mechanism includes a rotating column 201 arranged in the middle of the stirring box 103. A first stirring shaft 202 is arranged at the lower end of the rotating column 201. A sleeve 204 is sleeved on the upper end of the rotating column 201 through a bearing. A second stirring shaft 205 is arranged at the lower end of the sleeve 204. A number of stirring rollers 203 are evenly arranged on the second stirring shaft 205. A driving mechanism for driving the sleeve 204 is arranged at the upper end of the rotating column 201. The driving mechanism includes an upper arc tooth surface gear 206 arranged at the upper end of the rotating column 201. An installation frame 207 is arranged at the upper end of the stirring box 103. The top of the rotating column 201 is rotatably connected to the upper side wall of the installation frame 207. An arc bevel gear 208 meshing with the upper arc tooth surface gear 206 is rotatably arranged inside the installation frame 207. A lower arc surface gear 209 meshing with the arc bevel gear 208 is arranged at the upper end of the sleeve 204. A second motor 210 is arranged inside the installation frame 207. The output end of the second motor 210 is connected to the arc bevel gear 208 through a coupling. Starting the second motor 210 can make the arc bevel gear 208 rotate, and then make the upper arc tooth surface gear 206 and the lower arc surface gear rotate in opposite directions. The rotation of the upper arc tooth surface gear 206 makes the first stirring shaft 202 rotate to stir the concrete forward, and the reverse rotation of the lower arc surface gear can make the second stirring shaft 205 rotate, and then drive the stirring rollers 203 to rotate in the opposite direction to further stir the concrete in the reverse direction. The forward and reverse rotation stirring can more effectively make the components of the concrete fully mixed, reduce the stirring dead angle, make the concrete mixture more uniform, and is beneficial to improving the overall quality of the concrete.

[0026] As Figure 1 , 4 shown in the figure, a number of universal wheels 301 are evenly arranged at the lower end of the chassis 101. A brake pad 302 is arranged on each universal wheel 301. The universal wheels 301 allow the equipment to move flexibly in all directions at the construction site. Whether it is going straight, turning or adjusting the position in place, it can be easily achieved, which greatly facilitates the transfer and positioning of the equipment between different pouring areas. The brake pads 302 equipped on the universal wheels 301 can stop the equipment in time when the equipment stops pouring operations or needs to fix the position, preventing the equipment from accidentally sliding or moving.

[0027] Working principle: When using this device, first inject the concrete raw materials into the mixing tank 103 through the feeding port 104, and then start the second motor 210 to make the arc bevel gear 208 rotate, thereby making the upper arc tooth surface gear 206 and the lower arc tooth surface gear rotate in opposite directions. The rotation of the upper arc tooth surface gear 206 makes the first mixing shaft 202 rotate to mix the concrete in the forward direction. The reverse rotation of the lower arc tooth surface gear can make the second mixing shaft 205 rotate, thereby driving the mixing roller 203 to rotate in the reverse direction to further mix the concrete in the reverse direction. The forward and reverse mixing can more effectively make the components of the concrete fully mixed, reduce the dead corners of mixing, make the concrete mixture more uniform, and is beneficial to improving the overall quality of the concrete. The mixed concrete enters the pouring box 102. At the same time, starting the first motor 107 can make the mixing column 105 rotate, thereby making the output impeller 106 rotate. By precisely controlling the rotation speed and working state of the output impeller 106, the flow rate stability during the concrete pouring process can be achieved, which helps to reduce problems such as faults and cold joints during the construction process, so as to better discharge the concrete through the pouring port 108.

[0028] According to another embodiment of the present invention, as Figure 1 , 4 shown, a handle 303 is provided at the right end of the chassis 101, which provides a direct holding point, and the operator can more conveniently control and push the equipment.
