[0014] Furthermore, the method of the polystyrene particle lightweight concrete mixing device comprises the following steps: S1: Reciprocating mixing: The internal threaded sleeve will drive the strip-shaped mixing blades to rotate, and the strip-shaped mixing blades will rotate under the resistance of the concrete in the mixing barrel, and the strip-shaped mixing blades will mix the concrete in the mixing barrel. Under the action of the reciprocating screw, the internal threaded sleeve will reciprocate on the reciprocating screw. At this time, the internal threaded sleeve will drive several strip-shaped mixing blades to rotate and reciprocate, and the strip-shaped mixing blades will reciprocate to mix the concrete in the mixing barrel to increase the mixing range. During the rotation of the internal threaded sleeve, the cylinder will be driven to move synchronously, and the cylinder will drive the defoaming blades to rotate synchronously. The defoaming blades will break the bubbles in the concrete during the rotation process, so that the bubbles in the concrete are quickly discharged to prevent the bubbles from affecting the quality of the concrete; S2: Lifting stirring: The oblique internal thread scraper will drive the hollow cylinder to do lifting motion under the action of the reciprocating thread, and the corresponding strip stirring blades and defoaming paddles will rise and fall synchronously.

At this time, the overturning spring will be compressed and deformed. When the annular conical baffle drops to expose the discharge trough, under the centrifugal force of the rotation of the hollow cylinder, the concrete on the top of the annular conical baffle will be thrown out of the hollow cylinder from the discharge trough. At this time, the concrete inside the concrete will cover the polystyrene particles on the liquid surface. During the reciprocating movement of the hollow cylinder, the concrete will be continuously overturned, thereby improving the mixing efficiency of the polystyrene particles and concrete. When the hollow cylinder enters the concrete, the concrete will enter the position between the hollow cylinder and the annular conical baffle from the discharge trough. After the hollow cylinder leaves the liquid surface, the concrete remaining in the gap between the annular conical baffle and the hollow cylinder will be thrown out under the action of gravity and centrifugal force, further improving the mixing efficiency and preventing blockage between the annular conical baffle and the hollow cylinder. S4: Comprehensive stirring: the disc drives the rotating rod to rotate, the rotating rod drives the strip rod to rotate, the strip rod drives the circular sliding block to rotate, the circular sliding block drives the circular sleeve to rotate, the circular sleeve drives several stirring blades to rotate, and the stirring blades rotate under the resistance of the liquid at the same time. The stirring blades will stir the places that the strip stirring blades cannot reach. When the hollow cylinder descends, the strip limit plate will be driven down. The strip limit plate will contact the slope surface during the descent process. Under the action of the slope surface, the L-shaped plate will be driven to move away from the driving shaft. The L-shaped plate drives the circular sliding block to move. At this time, the strip rod is stretched and deformed, and the circular sliding block drives the circular sleeve to move. The circular sleeve drives several stirring blades to move. When the hollow cylinder rises, the strip limit plate will leave the L-shaped plate. At this time, the circular sliding block will recover under the elastic force of the strip rod. In the process of the reciprocating movement of the strip stirring blade, the stirring blade also reciprocates and rotates at the same time, thereby enhancing the stirring effect.

[0015] The present invention has the following beneficial effects: (1) The present invention relates to a polystyrene particle lightweight concrete mixing device. When in use, concrete and an appropriate amount of water are first added to the device for mixing, and then polystyrene particles are added for mixing. The driving motor is started, and the driving motor drives the driving shaft to rotate. The driving shaft drives the hollow cylinder to rotate under the action of the rectangular slide groove, and the hollow cylinder drives a plurality of reciprocating screws to rotate. The reciprocating screw drives the internal threaded sleeve to rotate, and the internal threaded sleeve drives the strip stirring blades to rotate. Under the action of the resistance of the concrete in the mixing barrel, the strip stirring blades are driven to rotate. The strip stirring blades stir the concrete in the mixing barrel. Under the action of the reciprocating screw, the internal threaded sleeve moves back and forth on the reciprocating screw. At this time, the internal threaded sleeve drives a plurality of strip stirring blades to rotate and reciprocate. The strip stirring blades stir the concrete in the mixing barrel back and forth to increase the mixing range. During the rotation of the internal threaded sleeve, the cylinder is driven to move synchronously, and the cylinder drives the defoaming blades to rotate synchronously. During the rotation of the defoaming blades, the bubbles in the concrete are broken, so that the bubbles in the concrete are quickly discharged to prevent the bubbles from affecting the quality of the concrete. (2) The present invention provides a polystyrene particle lightweight concrete mixing device. During the rotation of the hollow cylinder, the Z-shaped rod and the mounting rod are driven to rotate. The Z-shaped rod and the mounting rod are driven to rotate the oblique internal thread scraper. Under the action of the reciprocating thread, the oblique internal thread scraper drives the hollow cylinder to perform lifting motion. The corresponding strip stirring blades and defoaming blades are synchronously lifted and lowered. During the reciprocating movement and rotation of the defoaming blades and the strip stirring blades on the reciprocating screw, reciprocating lifting motions will occur simultaneously. At this time, the strip stirring blades will further expand the stirring range, and the corresponding defoaming blades will further expand the range of bubble elimination. When the strip stirring blades move to the liquid surface of the concrete, the strip stirring blades will bring the polystyrene particles just added to the liquid surface into the concrete. When the strip groove brings the polystyrene particles into the concrete liquid, the air in the strip groove will be discharged from the air vents, which can effectively prevent air from entering the concrete liquid, reduce the workload of the defoaming blades to discharge bubbles, and enable the bubbles to be discharged quickly. (3) The present invention provides a polystyrene particle lightweight concrete mixing device. During the process of the hollow cylinder rising, the concrete liquid is loaded into the upper part of the annular conical baffle in the hollow cylinder. When the hollow cylinder leaves the concrete liquid surface, the annular conical baffle contacts the L-shaped limit plate. The L-shaped limit plate causes the annular conical baffle to move downward. At this time, the material turning spring is compressed and deformed. When the annular conical baffle descends to expose the discharge trough, the concrete on the top of the annular conical baffle is thrown out of the hollow cylinder from the discharge trough under the centrifugal force of the rotation of the hollow cylinder. At this time, the concrete inside the concrete covers the polystyrene particles on the liquid surface. During the reciprocating movement of the hollow cylinder, The concrete will be continuously turned over in the mixing drum, thereby improving the mixing efficiency of the polystyrene particles and the concrete. When the hollow cylinder enters the concrete, the concrete will enter the position between the hollow cylinder and the annular conical baffle from the discharge trough. After the hollow cylinder leaves the liquid surface, the concrete remaining in the gap between the annular conical baffle and the hollow cylinder will be thrown out under the action of gravity and centrifugal force, further improving the mixing efficiency and preventing the annular conical baffle and the hollow cylinder from being blocked, which will affect the descent of the annular conical baffle. During the lifting and lowering process of the oblique internal thread scraper, the oblique internal thread scraper will scrape along the inner wall of the mixing drum, further enhancing the effect of air bubble discharge. (4) The present invention provides a polystyrene particle lightweight concrete mixing device. During the rotation of the driving shaft, the disk is driven to rotate, the disk drives the rotating rod to rotate, the rotating rod drives the bar rod to rotate, the bar rod drives the circular sliding block to rotate, the circular sliding block drives the circular sleeve to rotate, the circular sleeve drives a plurality of stirring blades to rotate, and the stirring blades simultaneously rotate under the resistance of the liquid. The stirring blades stir the places that the bar stirring blades cannot stir. When the hollow cylinder descends, the bar limiting plate is driven to descend, and the bar limiting plate contacts the slope during the descent. The L-shaped plate will move away from the driving shaft under the action of the slope surface, and the L-shaped plate will drive the circular sliding block to move. At this time, the strip rod will be stretched and deformed, and the circular sliding block will drive the circular sleeve to move. The circular sleeve will drive several mixing blades to move. When the hollow cylinder rises, the strip limit plate will leave the L-shaped plate. At this time, the circular sliding block will recover under the elastic force of the strip rod. In the process of the reciprocating movement of the strip mixing blades, the mixing blades also reciprocate and rotate at the same time, thereby enhancing the mixing effect and allowing the concrete in the mixing barrel to be fully mixed.

10. A method for using a polystyrene particle lightweight concrete mixing device, using the polystyrene particle lightweight concrete mixing device as claimed in claim 9, characterized in that: The steps are as follows: S1: reciprocating stirring: the internally threaded sleeve (504) drives the strip-shaped stirring blade (505) to rotate. Under the resistance of the concrete in the mixing barrel (1), the strip-shaped stirring blade (505) is driven to rotate. The strip-shaped stirring blade (505) stirs the concrete in the mixing barrel (1). Under the action of the reciprocating screw (503), the internally threaded sleeve (504) reciprocates on the reciprocating screw (503). At this time, the internally threaded sleeve (504) drives a plurality of strip-shaped stirring blades (505) to rotate. The mixing blade (505) rotates and reciprocates. The strip-shaped mixing blade (505) reciprocates to mix the concrete in the mixing barrel (1) to increase the mixing range. During the rotation of the internal threaded sleeve (504), the cylinder (508) is driven to move synchronously. The cylinder (508) drives the defoaming blade (509) to rotate synchronously. During the rotation of the defoaming blade (509), bubbles in the concrete are broken, so that the bubbles in the concrete are quickly discharged, thereby preventing the bubbles from affecting the quality of the concrete. S2: lifting and lowering stirring: the oblique internal thread scraper (513) drives the hollow cylinder (502) to perform lifting and lowering motion under the action of the reciprocating thread (510), and the corresponding strip-shaped stirring blade (505) and the defoaming blade (509) are lifted and lowered synchronously. During the reciprocating movement and rotation of the defoaming blade (509) and the strip-shaped stirring blade (505) on the reciprocating screw (503), a reciprocating lifting and lowering motion will occur simultaneously. At this time, the strip-shaped stirring blade (505) will further expand the stirring range, and the corresponding defoaming blade (509) will further expand the range of bubble elimination; S3: Overturning and stirring: When the hollow cylinder (502) leaves the concrete liquid surface, the annular conical baffle (704) contacts the L-shaped limit plate (705), and the L-shaped limit plate (705) causes the annular conical baffle (704) to move downward. At this time, the overturning spring (703) undergoes compression deformation. When the annular conical baffle (704) descends to expose the discharge trough (701), under the centrifugal force of the rotation of the hollow cylinder (502), the concrete on the top of the annular conical baffle (704) is thrown out of the hollow cylinder (502) from the discharge trough (701). At this time, the concrete inside the concrete covers the polystyrene particles on the liquid surface. The hollow cylinder (502) continuously overturns the concrete during the reciprocating movement, thereby improving the mixing efficiency of the polystyrene particles and the concrete. When the hollow cylinder (502) enters the concrete, the concrete enters the position between the hollow cylinder (502) and the annular conical baffle (704) from the discharge trough (701). After the hollow cylinder (502) leaves the liquid surface, the concrete remaining in the gap between the annular conical baffle (704) and the hollow cylinder (502) is thrown out under the action of gravity and centrifugal force, thereby further improving the mixing efficiency and preventing the annular conical baffle (704) and the hollow cylinder (502) from being blocked. S4: Comprehensive stirring: the disc (601) drives the rotating rod (602) to rotate, the rotating rod (602) drives the strip rod (603) to rotate, the strip rod (603) drives the circular sliding block (604) to rotate, the circular sliding block (604) drives the circular sleeve (605) to rotate, the circular sleeve (605) drives a plurality of stirring blades (606) to rotate, the stirring blades (606) simultaneously rotate under the resistance of the liquid, the stirring blades (606) stir the places that the strip stirring blades (505) cannot stir, when the hollow cylinder (502) descends, it drives the strip limiting plate (609) to descend, the strip limiting plate (609) contacts the slope surface (608) during the descent, and the slope surface Under the action of (608), the L-shaped plate (607) is driven to move in a direction away from the driving shaft (3), and the L-shaped plate (607) drives the circular sliding block (604) to move. At this time, the strip rod (603) is stretched and deformed, and the circular sliding block (604) drives the circular sleeve (605) to move. The circular sleeve (605) drives a plurality of stirring blades (606) to move. When the hollow cylinder (502) rises, the strip limit plate (609) leaves the L-shaped plate (607). At this time, the circular sliding block (604) is restored under the elastic force of the strip rod (603). During the reciprocating movement of the strip stirring blade (505), the stirring blade (606) also reciprocates and rotates at the same time, thereby enhancing the stirring effect.
