DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0020] A concrete mixing device with automatic bag opening, such as Figure 1-Figure 3 As shown, it includes a base 1, a fixing frame 2, a cylinder body 3 and a top cover 4. The upper side of the base 1 is connected to the fixing frame 2, the fixing frame 2 is connected to the cylinder body 3, the upper side of the cylinder body 3 is connected to the top cover 4, and the top cover 4 is provided with a discharge cover to facilitate the discharge of water.

[0021] like Figure 1-Figure 3As shown, it also includes a transfer port 5, a fixed plate 6, a rotating plate 7, a motor 8, a stirring blade 9 and a screen 10. The lower side of the cylinder body 3 is rotatably connected to the transfer port 5, and the transfer port 5 is rotatably connected to the base 1. The upper part of the base 1 is connected to the fixed plate 6, and the upper part of the base 1 is also rotatably connected to the rotating plate 7. The rotating plate 7 is located at the lower side of the fixed plate 6. A rotating rod is provided on the rotating plate 7. Both the fixed plate 6 and the rotating plate 7 are provided with a material discharge groove for aligning and discharging materials. The upper side of the fixed frame 2 is connected to the motor 8, and a stirring rod is provided on the output shaft of the motor 8. Three stirring blades 9 are rotatably connected to the stirring rod. The upper part of the cylinder body 3 is connected to the screen 10, and the screen 10 is rotatably connected to the stirring rod.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a cylinder needle 11, a material plate 12, a spring 13, a return hook 14 and a roller 15. The right part of the top cover 4 is rotatably connected to the front and rear cylinder needles 11, and the left side of the top cover 4 is rotatably connected to the material plate 12. A handle is provided on the material plate 12 for easy holding. The material plate 12 is slidably connected to the return hook 14, and the front and rear springs 13 are connected between the return hook 14 and the material plate 12. A plurality of rollers 15 are connected to the material plate 12.

[0023] When using the utility model, first place the base 1 in the mixing area of ​​the concrete, then rotate the material plate 12 counterclockwise to a vertical state to facilitate the placement of the cement bag, then place the cement bag on the return hook 14, and then rotate the material plate 12 to reset. After the material plate 12 is reset, the cement bag slides to the right on the roller 15 under the action of the gravity of the cement bag and contacts the cylinder needle 11 on the top cover 4, driving the return hook 14 to move to the right, and the spring 13 is stretched, and the cement bag is pierced and opened by squeezing the cylinder needle 11 and the cement bag. When encountering a cement bag that is difficult to pierce, the cylinder needle 11 can be rotated to assist in opening the bag. After the cement bag is pierced, the cement ash falls onto the screen 10 below for filtration, and the agglomerated cement is filtered out to avoid affecting the quality of the concrete. The filtered cement ash falls into the cylinder body 3 below, and the spring 13 rebounds, driving the return hook 14 to reset, driving the remaining cement bags to move to the left for easy collection, and then open the unloading cover on the top cover 4, add water into the cylinder body 3, and after the water and cement fall into the cylinder body 3, start the motor 8 on the fixed frame 2 to rotate the stirring blade 9 to stir the water and cement. When the concrete mixing is completed, the rotating plate 7 is rotated to align with the fixed plate 6 through the rotating rod, so that the concrete falls from the unloading trough on the fixed plate 6 and the rotating plate 7 to the transfer port 5 below. The transfer port 5 is rotated to adjust the concrete so that the concrete can be discharged from different directions, thereby automatically opening the cement bag when the concrete is mixed, reducing the labor intensity of the staff and being more convenient.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
