[0031] The surface of the mixing box 1 is provided with a stirring mechanism 2, and the stirring mechanism 2 includes a bidirectional motor 201, a bottom stirring blade 205 and a connecting rod 209. The bidirectional motor 201 is fixedly installed on the left side of the L-shaped plate 7, and the bottom stirring blade 205 is arranged at the bottom of the inner cavity of the mixing box 1. The bottom of the bottom stirring blade 205 contacts the bottom of the inner cavity of the mixing box 1, and the connecting rod 209 is arranged at the bottom of the mixing box 1. The first stirring blade 210 is fixedly installed on the four sides of the surface of the connecting rod 209, and the second stirring blade 212 is arranged on the four sides of the top of the bottom stirring blade 205. The output end of the top of the bidirectional motor 201 is fixedly connected to the first active synchronous shaft 202, and the middle end of the bottom of the mixing box 1 is movably connected with the shaft sleeve 203. The surface of the shaft sleeve 203 and the first synchronous belt 204 are movably connected with the first synchronous belt 204. The top of the first synchronous belt 204 is fixedly connected to the bottom of the bottom stirring blade 205, and the output end of the bottom of the bidirectional motor 201 is fixedly connected to the second active synchronous shaft The surface of the shaft 206 and the L-shaped plate 7 are movably connected to the driven synchronous shaft 207, and the surfaces of the second active synchronous shaft 206 and the driven synchronous shaft 207 are movably connected to the second synchronous belt 208. The bottom of the connecting rod 209 is fixedly connected to the top of the driven synchronous shaft 207. The size of the connecting rod 209 matches the size of the inner side of the shaft sleeve 203 and the bottom stirring blade 205. The connecting rod 209 passes through the inner side of the shaft sleeve 203 and the bottom stirring blade 205 and extends into the inner cavity of the mixing box 1. The surface of the connecting rod 209 is movably connected to the inner side of the shaft sleeve 203 and the bottom stirring blade 205 through a bearing.

[0032] By setting up the stirring mechanism 2, through the output at the top of the bidirectional motor 201, the first active synchronous shaft 202 and the first synchronous belt 204 cooperate with each other, and drive the sleeve 203 and the bottom stirring blade 205 to rotate. Due to the rotation of the bottom stirring blade 205, the scraper 211 and the second stirring blade 212 rotate synchronously, and the output end at the bottom of the bidirectional motor 201 drives the second active synchronous shaft 206 to rotate.

At the same time, since the bottom of the bottom stirring blade 205 is in contact with the bottom of the inner cavity of the mixing box 1, the bottom stirring blade 205 can synchronously stir the settled cement and coarse and fine aggregates, effectively avoiding the situation where the cement and coarse and fine aggregates are unable to contact the stirring blades when they are precipitated, resulting in the mixed concrete being unable to be uniformly formed, thereby affecting the qualified rate of concrete forming, and facilitating the use of operators. By setting the scraper 211, the concrete on the inner wall of the mixing box 1 can be scraped off when the concrete after mixing is discharged, thereby avoiding the problem that part of the concrete cannot be discharged normally and remains on the inner wall of the mixing box 1, resulting in concrete waste.

[0033] Example 2

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, a base plate 11 is fixedly installed at the bottom of the mixing box 1, and anchor bolts 12 are threadedly connected on all four sides of the top of the base plate 11. Mounting bolts 8 are threadedly connected on all four sides of the top of the box cover 3, and the bottoms of the six mounting bolts 8 are threadedly connected to the inner surface of the mixing box 1. A flange 9 is fixedly installed at the bottom of the discharge pipe 6, and screw grooves 10 are provided on the surface of the flange 9.

[0035] By providing the anchor bolts 12, the overall stability of the equipment can be improved, and the overall equipment can be prevented from tipping over due to accidental collision, thereby preventing the concrete mixing work from being completed. By providing the mounting bolts 8, the box cover 3 can be easily disassembled, and the operator can perform daily repairs and maintenance on the components inside the mixing box 1. By providing the flange 9 and the screw groove 10, the discharge pipe 6 can be conveniently connected to the external device for holding concrete, thereby facilitating the discharge of concrete.

[0036] When the utility model is working: first, cement, coarse and fine aggregates and water are poured into the inner cavity of the mixing box 1 through the feed port 4, and then the first active synchronous shaft 202 is driven to rotate through the output end at the top of the bidirectional motor 201. As the first active synchronous shaft 202 rotates, the first synchronous belt 204 drives the shaft sleeve 203 to rotate synchronously, and causes the bottom stirring blade 205 to rotate. As the bottom stirring blade 205 rotates, the scraper 211 and the second stirring blade 212 rotate synchronously. At the same time, the output end at the bottom of the bidirectional motor 201 drives the second active synchronous shaft 206 to rotate in the opposite direction to the first active synchronous shaft 202, and causes the second synchronous belt 208 to drive the driven synchronous shaft 207 to rotate. As the driven synchronous shaft 207 rotates, the connecting rod 209 drives the first stirring blade 210 to stir, thereby completing the molding work of concrete mixing.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
