Firstly, concrete with the density in a standard value range is injected into the spherical shell 132 through an injection molding nozzle on the spherical shell 132, when cement slurry in a first storage box 2 preliminarily enters the mixing drum 4 through the feeding pipe 7, the cement slurry can firstly fall into the material receiving box 135 and then flows into the U-shaped pipe due to the fact that the material receiving box 135 is located right below the outlet end of the feeding pipe 7, liquid level positions of two ends of the cement slurry entering the U-shaped pipe are mutually leveled according to the principle of a communicating device, the liquid level position of the cement slurry in the left section of the U-shaped pipe can synchronously rise along with the continuous rising of the liquid level position of the cement slurry in the right section of the U-shaped pipe, and the air pressure balance valve unit 139 can guarantee that the air pressure in the drum 131 is balanced with the air pressure outside;

Because the density of the cement slurry before the cement slurry is completely mixed with the foaming agent is greater than that after the cement slurry is completely mixed, the spherical shell 132 and the cement slurry entering the U-shaped pipe generate upward buoyancy under the action of density difference, the spherical shell 132 rises to drive the ejector rod 137 to rise, the ejector rod 137 then drives the second valve plate 134 to rise by pulling the elastic pull rope 138, the second valve plate 134 closes the discharge pipe 11, and the cement slurry entering the right section of the U-shaped pipe can overflow into the stirring cylinder 4 after rising to the right end opening of the U-shaped pipe until the whole stirring cylinder 4 is completely filled;

in the process of stirring and mixing cement slurry and a foaming agent by driving the elastic paddle board 6 to rotate by the driving motor 5, the cement slurry and the foaming agent are gradually mixed, the density of the cement slurry is gradually reduced from thick to thin, after the cement slurry is fully mixed with the foaming agent, the density of the cement slurry is slightly smaller than that of the spherical shell 132, therefore, the spherical shell 132 can descend under the action of density difference, the spherical shell 132 drives the ejector rod 137 to descend, the ejector rod 137 descends to drive the elastic pull rope 138 to recover to a loose state, the second valve plate 134 loses the tension of the elastic pull rope 138 and slides rightwards under the action of gravity due to the inclined state that the left part of the second valve plate is higher than the right part of the second valve plate 134 until the second valve plate 134 completely slides in, at the moment, the circular through hole on the second valve plate 134 is aligned with the inner cavity of the discharge pipe 11, the discharge pipe 11 is in an open state, the cement slurry flows out from the discharge pipe 11 after the mixing is completed, the cement paste within the range of the composite standard value after mixing can be discharged in time.

Referring to fig. 7, in the present embodiment, a siphon 20 is fixedly connected to an end surface of the material receiving box 135 through a cross bar, the siphon 20 is in an inverted U shape, a left end of the siphon 20 extends to a corner of an inner cavity of a right portion of the U-shaped tube, and a right end of the siphon 20 is lower than a left end thereof.

In the process that cement paste is gradually discharged from the discharge pipe 11 after mixing is finished, the liquid level position of the cement paste in the mixing drum 4 slowly descends, the floating ball 901 also descends along with the descending of the liquid level of the cement paste in the mixing drum 4, the floating ball 901 drives the telescopic support rod 902 to slowly rotate anticlockwise, the telescopic support rod 902 is loosened from the press type touch switch, the driving motor 5 and the driving motor 157 stop running, the telescopic support rod 902 then drives the disc 16 to rotate through the turntable and the pulley component 911, the disc 16 then pushes the second sliding rod 908 to move leftwards through the telescopic plate 910, as the first magnetic block 905 and the second magnetic block 906 attract each other after the first valve plate 904 closes the feed pipe 7, at the moment, the second sliding rod 908 moves leftwards, so that the pulling spring 909 is pulled;

when the floating ball 901 contacts the tail end of the bottom of the mixing drum 4 immediately after the cement slurry in the mixing drum 4 is discharged, the pulling spring 909 is pulled to the maximum length, the gravity of the floating ball 901 is greater than the force of mutual attraction of the first magnetic block 905 and the second magnetic block 906, therefore, at this time, the second sliding rod 908 pulls the first sliding rod 907 to move leftwards by pulling the spring 909, the first sliding rod 907 then drives the first valve plate 904 to move leftwards, the first magnetic block 905 and the second magnetic block 906 which are sucked together are forcibly separated from each other, the feeding pipe 7 is opened again, after the cement slurry in the stirring cylinder 4 is completely emptied, since the right end of the siphon tube 20 is lower than the left end thereof, the cement paste in the bent section of the U-shaped tube is pumped out by the siphon tube 20 under the action of siphon, and the cement paste in the feeding tube 7 flows into the stirring cylinder 4 again after the storage box 2 is reopened for mixing treatment.

When the automatic foaming agent pouring device works, firstly cement paste is poured into a first storage box 2, foaming agent is poured into a second storage box 3, the cement paste in the first storage box 2 firstly flows into a second automatic opening and closing mechanism 13 through a feeding pipe 7, the second opening and closing mechanism controls a discharging pipe 11 to be closed, then the cement paste flows into a stirring cylinder 4, the liquid level of the cement paste in the stirring cylinder 4 is gradually increased, the gradually increased cement paste drives a floating ball 901 to rise, when the cement paste in the stirring paddle rises to a specified liquid level, the floating ball 901 also rises to the highest position, at the moment, the first automatic opening and closing mechanism 9 controls the feeding pipe 7 to be closed, meanwhile, a telescopic support rod 902 in the first automatic opening and closing mechanism 9 touches a pressing type touch switch 18 to start a driving motor 5 and a driving motor 157, an intermittent feeding mechanism 15 intermittently feeds the foaming agent into the stirring cylinder 4, the driving motor 5 drives an elastic paddle plate 6 to rotate to stir and mix the cement paste and the foaming agent, the cement slurry is gradually thinned from thick to thin in the mixing process, the density is gradually reduced, the density of the cement slurry is smaller than that of a sample in the spherical shell 132 after the cement slurry is completely mixed with the foaming agent, the spherical shell 132 can descend, the discharge pipe 11 is controlled to be opened by the second automatic opening and closing mechanism 13 at the moment, the cement slurry is discharged after stirring is completed, the floating ball 901 descends along with the descending of the liquid level of the cement slurry in the process of gradually discharging the cement slurry in the stirring cylinder 4, the first automatic opening and closing mechanism 9 is restored to the initial position after the cement slurry in the stirring cylinder 4 is completely discharged, the feed pipe 7 is in the opened state again, the steps are repeated again, and the circulation is repeated, so that the cement slurry and the foaming agent are stirred and mixed for times.
