[0002] The demand for high-performance concrete in the construction industry continues to increase, and the demand for high-quality graphene-modified cement concrete is also growing. When extruding concrete, in order to reduce the sticking and blockage of the discharge port, an appropriate amount of water can be added to moisten the concrete, reduce adhesion, and thus improve the discharge effect.

[0033] 1. A discharging structure is provided. Concrete and graphene are added into the storage box through a feeding pipe. Pressurized water is added into the storage box and the connecting pipe through a water feeding pipe. The stirred and mixed concrete material is transported into the extrusion barrel through a discharging pipe. The motor is started to work. The motor drives the rotating drum to rotate. The rotating drum drives the inner rod to rotate through a limit bar. The inner rod drives the rotating rod to rotate. The rotating rod drives the stirring rod and the spiral extrusion piece to rotate, thereby further stirring and mixing the concrete material. The spiral extrusion piece is used for extrusion operation. The vibration motor assists in mixing the concrete material. The rotating drum also drives the half gear to rotate. The half gear drives the driven gear to rotate. The rotation of the driven gear acts on the torsion spring and drives the linear movement of the threaded sleeve. When the half gear is separated from the driven gear, the torsion spring drives the driven gear to reset. At this time, the threaded sleeve moves and resets, thereby realizing the linear reciprocating movement of the threaded sleeve and the moving plate. The moving plate can drive the fixed ring to move through the U-shaped block and the sliding rod. The fixed ring drives the rotating rod and the inner rod to move. The inner rod can be inserted into the rotating drum, and the limit bar limits the inner rod to maintain the transmission of the rotating drum and the inner rod, so as to facilitate the movement and stirring of the stirring rod; and the moving plate drives the movable rod to move back and forth, and the movable rod drives the piston to move. When the piston stretches the spring, the one-way valve 2 is closed, and the one-way valve 1 is connected. The gas in the air pipe is squeezed into the connecting pipe and the connecting pipe, and then a small amount of pressurized water inside the connecting pipe is sprayed out through the mounting ring and the nozzle head, and the water body has pressure, which prevents the concrete material from entering the nozzle head. When the piston compresses the spring, the one-way valve 1 is closed, and the one-way valve 2 is connected, and air is taken in through the air inlet pipe, so as to facilitate the extrusion of the concrete material. A small amount of water is added to moisten the position of the conical cylinder, which reduces the solidification and blockage of the concrete material at the conical cylinder, improves the discharging effect, and solves the problem that the concrete residue at the discharge port of the extrusion device may be stuck or block the discharge port, affecting the subsequent concrete extrusion and discharging, thereby reducing the working efficiency of the equipment;

[0034] 2. A stirring structure is provided. By starting the second motor, the second motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral blade and the stirring plate to rotate. The stirring plate stirs and mixes the graphene and concrete. The spiral blade is convenient for subsequent discharging. The spiral blade drives the rotating part to rotate through the vertical bar. The rotating part can slide on the outside of the rotating shaft. The stirring plate drives the adjusting rod to rotate at the same time. When the adjusting rod rotates to the low side position of the annular chute, the rotating part and the scraper rise. When the adjusting rod rotates to the high side position of the annular chute, the rotating part and the scraper descend. Therefore, while stirring, the rotating part and the scraper move up and down and rotate to scrape, which reduces the adhesion of concrete materials on the inner wall of the storage box and improves the mixing effect and mixing accuracy.

The spiral blade 73 drives the rotating member 75 to rotate through the vertical bar 711, and the rotating member 75 can slide on the outside of the rotating shaft 72. The stirring plate 74 drives the adjusting rod 78 to rotate at the same time. When the adjusting rod 78 rotates to the low side position of the annular chute 76, the rotating member 75 and the scraper 79 rise. When the adjusting rod 78 rotates to the high side position of the annular chute 76, the rotating member 75 and the scraper 79 descend. Therefore, while stirring, the rotating member 75 and the scraper 79 move up and down and rotate to scrape, thereby reducing the adhesion of concrete material on the inner wall of the storage box 3, and improving the mixing effect and mixing accuracy.

[0069] Working principle: When using the device, first, Figure 1-Figure 11As shown, concrete and graphene are added to the storage box 3 through the feeding pipe 8, and pressurized water is added to the storage box 3 and the connecting pipe 10 through the water feeding pipe 9. By starting the motor 2 71, the stirring plate 74 stirs and mixes the graphene and concrete. The stirring plate 74 drives the adjustment rod 78 to rotate at the same time, and the rotating member 75 and the scraper 79 move up and down and rotate to scrape, thereby reducing the adhesion of concrete material on the inner wall of the storage box 3. The stirred and mixed concrete material is transported to the extrusion barrel 5 through the discharge pipe 11, and the motor 1 62 is started to work, and the rotating rod 66 The stirring rod 67 and the spiral extrusion piece 68 are driven to rotate, thereby further stirring and mixing the concrete material. The rotating drum 63 also drives the half gear 69 to rotate, realizing the linear reciprocating movement of the threaded sleeve 616 and the movable plate 615. The movable plate 615 drives the movable rod 625 to reciprocate, so that a small amount of pressurized water inside the connecting pipe 10 is sprayed out through the mounting ring 630 and the nozzle head 631, so that when the concrete material is extruded, a small amount of water is added to moisten the position of the conical cylinder 12, thereby reducing the solidification and blockage of the concrete material at the conical cylinder 12.
