AI Technical Summary
The mixing efficiency of existing concrete spraying devices is low, resulting in insufficient concrete mixing and affecting the spraying effect.
The mixing drum and a stirring paddle are used to place an obliquely positioned mixing drum and the stirring paddle are arranged on the side close to the first inclined plate. The motor drives the stirring paddle to rotate to ensure that the stirring paddle enters the mixing drum as much as possible and achieves efficient stirring.
Through the combination design of the oblique mixing barrel and the stirring paddle, more high-ductility concrete can be flowed out of the mixing barrel, reducing the margin, achieving more complete mixing and improving the mixing efficiency.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0023] like Figure 1-Figure 4 As shown, the utility model discloses a high ductility concrete spraying device, comprising a flatbed truck 1, a mixing structure 2 and a spraying structure 3. A handrail is fixedly arranged on the top of the flatbed truck 1, and four universal wheels are arranged on the bottom of the flatbed truck 1. The flatbed truck 1 is a conventional structure and will not be described in detail here.
[0024] The mixing structure 2 is arranged on the top of the flatbed car 1, and includes a support frame 21, a mixing barrel 22, a barrel cover 23, a stirring paddle 24 and a motor 25. The support frame 21 is fixed to the top of the flatbed car 1, and the support frame 21 includes a support leg 211, a first inclined plate 212 and a second inclined plate 213. The support leg 211 is fixed to the top of the flatbed car 1, and the top of the support leg 211 is fixedly connected to the first inclined plate 212 and the second inclined plate 213. The connection between the first inclined plate 212 and the second inclined plate 213 is connected by welding, and the first inclined plate 212 and the second inclined plate 213 are vertically distributed. The barrel wall of the mixing barrel 22 abuts against the first inclined plate 212, and the barrel bottom of the mixing barrel 22 abuts against the second inclined plate 213. In order to prevent the mixing barrel 22 from rolling off the support frame 21, the first inclined plate 212 is also fixed with two symmetrically distributed card plates 214, and the card plates 214 abut against the side walls of the mixing barrel 22.
[0025] The mixing barrel 22 is provided with an extension plate 221 at the barrel opening, and the barrel opening is covered with a barrel cover 23, which is also provided with an extension plate 221. The two extension plates 221 are connected by bolts, so as to realize a detachable connection between the barrel cover 23 and the mixing barrel 22. Figure 2 As shown, a through hole is opened at the lower center of the barrel cover 23, and a stirring paddle 24 is inserted into the through hole. One end of the stirring paddle 24 extends to the bottom of the mixing barrel 22, and the other end of the stirring paddle 24 is connected to the output shaft of the motor 25. The motor 25 is fixedly or detachably connected to the barrel cover 23 through a motor frame, and the motor 25 is arranged outside the mixing barrel 22. Figure 3 As shown, the barrel cover 23 is also provided with a feed port 231 .
[0026] The spraying structure 3 includes a discharge pipe 31, a nozzle 32 and an air compressor 33. The head end of the discharge pipe 31 passes through the second inclined plate 213 and is connected to the discharge port of the mixing barrel 22. The discharge port is arranged on the bottom wall of the mixing barrel 22, and the discharge port is as close to the flatbed truck 1 as possible. The tube body of the discharge pipe 31 is placed on the flatbed truck 1, and the tail end of the discharge pipe 31 is fixed on the inclined surface of the fixing frame 4, so that the tail end of the discharge pipe 31 has a certain inclination, which is convenient for spraying. Obviously, the fixing frame 4 can also be replaced with other lifting structures to facilitate the adjustment of the spraying angle, but this part is not the content to be protected by the utility model, so it will not be repeated. The tail end of the discharge pipe 31 is sealed with a nozzle 32, and the side wall of the discharge pipe 31 is also sealed with the air compressor 33, so that high ductility concrete can be sprayed out from the nozzle 32. The discharge pipe 31 and the discharge port of the mixing barrel 22 are provided with valve bodies, and the opening and closing of the valve bodies can be controlled to control the concrete to flow into the discharge pipe and then be sprayed out through the nozzle.
[0027] When in use, high ductility concrete is poured into the mixing barrel 22 from the feed port 231, and the motor 25 is started, and the motor 25 drives the stirring paddle 24 to rotate, so that the high ductility concrete is fully stirred. Then, the high ductility concrete enters the discharge pipe 31, and then is sprayed out from the nozzle 32, and the spraying is completed.
[0028] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of 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.
