Description

Technical Field

[0001] This invention relates to the field of foamed concrete pouring on construction sites, and particularly to a mobile foamed concrete molding and pouring system for construction sites. Background Technology

[0002] Foamed concrete is a new type of lightweight, heat-insulating, sound-insulating, and fire-resistant building material. It is made by mixing a foaming agent with cement, water, sand, and other materials, fully foaming the foaming agent through a foaming machine's foaming system, uniformly mixing the foam with cement slurry, and then pumping it on-site or molding it into molds. Finally, it is formed into a porous material containing a large number of closed pores under natural curing.

[0003] Currently, before pouring foamed concrete on a construction site, the raw materials for foamed concrete need to be mixed and stirred before being pumped and poured. However, the existing mixing equipment for manufacturing foamed concrete is too large and can only prepare and pour foamed concrete at fixed points. The application scenarios are limited and fixed. The amount of foamed concrete mixed each time is too large and the accuracy is not high. In addition, too much foamed concrete prepared at one time will cause material waste, while too little foamed concrete needs to be prepared again, which will affect the overall pouring efficiency and is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile foamed concrete molding and pouring system for construction sites. It has an ingenious structure and can be adapted to various construction sites and usage scenarios through a mobile carrier. It can also prepare foamed concrete and control the amount of foamed concrete during the movement process, making it convenient and practical.

[0005] The technical solution for achieving the objective of this invention is as follows: This invention has a mobile carrier with an inner chamber. The mobile carrier has side doors that are rotatably connected to it under the drive of a motor. Each side door controls the opening and closing of the inner chamber through rotation. The inner chamber contains a hopper for holding powder and multiple mixing drums located below the hoppers and equipped with pouring pipes. A material distribution mechanism is provided between the hoppers and the mixing drums to inject the powder from the hoppers into the mixing drums. The material distribution mechanism includes a frame located within the inner chamber, a first motor fixed to the frame, a first movable frame slidably mounted on the frame under the drive of the first motor, and a second motor fixed to the first movable frame. A second movable frame, slidably mounted on a first movable frame under the drive of a second motor; a mounting frame mounted on the second movable frame; and a receiving assembly mounted on the mounting frame. The receiving assembly includes an upper cylinder group and a lower cylinder group mounted on the mounting frame; a receiving box, lifted and lowered on the mounting frame under the combined drive of the upper and lower cylinder groups; a feed pipe located at the upper end of the receiving box and communicating with it; a discharge pipe located at the lower end of the receiving box and communicating with it; and a first control valve located on the discharge pipe and controlling the flow of material discharge. The bottom of the hopper is provided with a discharge pipe communicating with the hopper and capable of discharging powder from the hopper. A sealing plug is provided inside the discharge pipe. The moving direction of the movable frame and the moving direction of the second movable frame are perpendicular. The upper cylinder group includes multiple first cylinders distributed circumferentially along the axis of the feed pipe on the mounting frame and capable of driving the receiving box to rise. The lower cylinder group includes multiple second cylinders distributed circumferentially along the axis of the discharge pipe on the mounting frame and capable of driving the receiving box to fall. The two ends of each first cylinder are rotatably connected to the mounting frame and the feed pipe, respectively. The two ends of each second cylinder are rotatably connected to the mounting frame and the discharge pipe, respectively. The upper end of the feed pipe is provided with an upper connecting sleeve integrally formed with and communicating with the feed pipe. The upper connecting sleeve is provided with a push rod that can push the sealing plug in the discharge pipe upward. The upper connecting sleeve is driven by each of the first cylinders. The drive sleeve of the receiving box is connected to the outer wall of the discharge pipe. The feed pipe is connected to the discharge pipe through the upper connecting sleeve and after the top rod pushes the sealing plug upward, it is connected to the discharge pipe of the hopper. After the receiving box finishes receiving the material, it is disengaged from the discharge pipe by the drive of the second cylinder. After the discharge pipe receives the material in the receiving box and is disengaged from the discharge pipe, it is extended into the corresponding mixing tank by the drive of the second cylinder. After the first control valve is opened, the powder in the receiving box is introduced into the mixing tank. The mixing tank is introduced into the mixing tank through the external pipe, and the powder in the receiving box is introduced into the mixing tank for mixing. The pouring pipe on the mixing tank is introduced into the external pipe with foaming agent and mixed with concrete. The formed foamed concrete is then discharged and poured.

[0006] Furthermore, the inner wall of the aforementioned feeding pipe is provided with feeding grooves coaxially arranged with the feeding pipe. One end of each feeding groove is located on the inner wall of the feeding pipe, and the other end of each feeding groove extends along the axial direction of the feeding pipe to communicate with the hopper. The side of the sealing plug is provided with feeding slides adapted to each feeding groove. One end of each feeding slide is located on the side of the sealing plug, and the other end of each feeding slide extends along the axial direction of the feeding pipe away from the hopper to below the sealing plug. When each feeding slide slide slides to the bottom of the feeding groove, the sealing plug closes the feeding pipe. During the upward sliding process of each feeding slide, the sealing plug disengages from the feeding pipe and opens the feeding pipe to allow feeding. The lower end of the slider is provided with a discharge ramp to remove residual powder in the discharge chute. The discharge ramp extends obliquely from the surface of the discharge slider away from the sealing plug to the surface of the discharge slider connected to the sealing plug. During the downward movement of the sealing plug, the discharge ramp discharges the powder in the discharge chute into the discharge pipe. The bottom of the sealing plug is provided with a positioning bottom hole into which a push rod can be inserted. A magnetic block is fixed in the positioning bottom hole. An electromagnet is fixed at the upper end of the push rod. The push rod pushes open the sealing plug by driving the feed pipe with each first cylinder. After receiving the material, the sealing plug is pressed down by the cooperation of the electromagnet and the magnet, as well as the cooperation of the discharge slider and the discharge chute, and the discharge pipe is closed.

[0007] Furthermore, the aforementioned inner chamber contains multiple hoppers for holding different powders. A lifting cylinder is fixedly mounted on the second movable frame. A rotary motor is mounted on the extension end of the lifting cylinder. The mounting frame is located at the output end of the rotary motor. The mounting frame has two oppositely arranged receiving components. Each feed pipe is equipped with a feed control valve. A mixing box is located below the mounting frame. The discharge pipes on each receiving component are oppositely arranged and converge on the mixing box. A guide pipe communicating with the mixing box is located below the mixing box. A second control valve is mounted on the guide pipe. A mixing motor is fixedly mounted on the mixing box. The mixing box contains a mixing shaft that can be rotated and positioned within the mixing box under the drive of the mixing motor, and multiple hoppers circumferentially distributed along the axis of the mixing shaft. The mixing blades on the material shaft, the mixing box and the mounting frame are provided with multiple bottom telescopic rods, the fixed end of each bottom telescopic rod is set on the mounting rod, and the telescopic end of each bottom telescopic rod is set on the mixing box. Each receiving box is provided with a scale groove, and a transparent scale plate is installed in the scale groove to measure the powder in the receiving box. Each receiving box is extended into the corresponding hopper to receive material by the drive of the mounting frame by the rotary motor and the drive of the feed pipe by the first cylinder. The powder in each receiving box is introduced into the mixing box through the discharge pipe. Each mixing blade is driven by the mixing motor to the mixing shaft to disperse and mix the powder. After the lifting cylinder drives the guide pipe to extend into the mixing tank, the second control valve is opened to introduce the proportionally mixed powder into the mixing tank.

[0008] Furthermore, the aforementioned inner chamber is equipped with two rows of mixing tanks and a built-in foamer. Each row of mixing tanks corresponds to a side door. The outside of each mixing tank is equipped with a mixing bracket to support it. Each mixing tank is equipped with a mixing motor, and each mixing tank is equipped with a mixing shaft. The mixing shaft is rotated inside the mixing tank by the driving of the mixing motor. The mixing shaft is equipped with mixing blades. A material pump is installed on the mixing tank, and the pouring pipe is installed at the output end of the material pump. The built-in foamer is equipped with a foaming pump. The built-in foamer introduces foaming agent into the mixing tank through a pipe. One end of the pipe is connected to the output end of the foaming pump, and the other end of the pipe extends into the mixing tank and communicates with it. The mixing blades, driven by the mixing motor to the mixing shaft, mix the powder, foaming agent, and mixing liquid in the mixing tank, and then pour the mixture through the pouring pipe driven by the material pump.

[0009] Furthermore, each mixing tank has an adjustment assembly on its outer wall for winding and unwinding the pouring pipe. The adjustment assembly includes a positioning shaft fixed to the outer wall of the mixing tank, a connecting sleeve rotatably sleeved on the positioning shaft, and a torsion spring disposed between the positioning shaft and the connecting sleeve. The two ends of the torsion spring act on the positioning shaft and the connecting sleeve, respectively. A limiting baffle is provided at the end of the connecting sleeve away from the mixing tank. The pouring pipe is wound around the connecting sleeve, with one end connected to a material pump and the other end fixedly equipped with a pouring pipe connector. Multiple circumferential rings along the axis of the connecting sleeve are provided on the outer wall of the connecting sleeve. A first hook is distributed on the outer wall of the connecting sleeve and is arranged in a hook shape. A second hook that can be adapted to the first hook is rotatably connected to the outer wall of the mixing tank. A connecting plate is fixedly provided on the outer wall of the mixing tank. A pressure rod is slidably provided on the connecting plate. A pressure block is fixedly provided on one end of the pressure rod near the second hook. A compression spring is provided between the pressure block and the connecting plate. The compression spring is sleeved on the pressure rod, and the two ends of the compression spring act on the pressure block and the connecting plate respectively. The pressure block is pressed against the second hook by the continuous force of the compression spring. After the casting pipe is pulled out, it is positioned by the continuous force of the torsion spring and the pressure of the first hook and the second hook.

[0010] Furthermore, each mixing tank is equipped with a top cover, and the top cover has a feed hole through which the feed pipe can pass. A sealing rubber sheet is fixedly installed on the feed hole, and the sealing rubber sheet has a cross opening. The feed pipe is driven by a lifting cylinder to pass through the cross opening on the sealing rubber sheet and extend into the mixing tank for feeding.

[0011] Furthermore, the aforementioned stirring shaft is provided with cleaning rods arranged opposite each other. The extension direction of the cleaning rods is perpendicular to the axis of the stirring shaft. Each cleaning rod has a brush head at the end away from the stirring shaft. Each brush head scrapes the powder remaining on the inner wall of the stirring tank by driving the stirring shaft through the stirring motor.

[0012] Furthermore, the inner chamber is equipped with multiple rotating platforms corresponding to each mixing tank and capable of rotating under the drive of a motor. The mixing support is mounted on the rotating platform, and the mixing support has opposing rotating rods. Each rotating rod has a support groove, one end of which is mounted on the corresponding rotating rod, and the other end of which extends along the extension direction of the rotating rod to the lower end of the rotating rod. Each mixing tank has a shaft block at both ends that can be embedded into the corresponding support groove. Each mixing tank is rotatably connected to the opposing rotating rod through the cooperation of the shaft block and the corresponding support groove. Each support groove has a stop block to prevent the shaft block from falling out of the support groove. Each stop block is fixed in the support groove by a locking device. The mixing support is equipped with a third cylinder corresponding to each rotating rod. The two ends of each third cylinder are rotatably connected to the mixing support and the rotating rod, respectively. After the mixing tank is opened from the side, it is transferred to the outside of the inner chamber by the driving of the mixing support by the rotating platform and the driving of each rotating rod by the third cylinder.

[0013] Furthermore, the aforementioned mobile vehicle also includes a rear compartment. The rear end of the mobile vehicle has a rear door panel that rotates on the vehicle via a motor. The rear compartment has a horizontally arranged partition, dividing it into a storage compartment for tools or parts and a spare compartment. The spare compartment contains a construction vehicle. The rear door panel rotates under the drive of the motor until it rests against the ground, forming a ramp for the construction vehicle to move. The construction vehicle has an inner cavity for holding foamed concrete. The construction vehicle is equipped with a mixing motor. The inner cavity contains a mixing shaft fixed to the mixing motor and mixing blades mounted on the mixing shaft. The construction vehicle also has a material pump and a pouring pipe connected to the material pump.

The spare compartment has a charging interface that connects to the charging connector to charge the mobile power supply. The mobile vehicle has a built-in power supply, and the charging interface is electrically connected to the mobile vehicle's built-in power supply.

[0014] Furthermore, each side door is equipped with multiple solar panels, each of which is electrically connected to the mobile vehicle's built-in power supply. Each solar panel is charged when each side door is opened.

[0015] The present invention has the following positive effects: (1) The present invention sets up a material distribution mechanism between the silo and each mixing tank. The material receiving component on the mounting frame is transferred to the bottom of the silo by the drive of the first moving frame and the second moving frame. The feeding pipe can be extended into the silo by the drive of each first cylinder to receive the material. Then, the material receiving box is transferred to the top of the corresponding mixing tank by the drive of the first moving frame and the second moving frame. The discharge pipe below the material receiving box is extended into the mixing tank by the drive of the second cylinder and introduces the powder into the mixing tank for mixing after the first control valve is opened. By setting up multiple first cylinders and second cylinders, the stability of the feeding pipe and the discharge pipe during the lifting or lowering process can be ensured. By setting up the material receiving component and cooperating with the first moving frame and the second moving frame, the material receiving component can be used to ensure the stability of the material receiving pipe during the lifting or lowering process. Select the appropriate mixing drum for material distribution according to the on-site pouring requirements. The mobile carrier can be adapted to various usage scenarios. By controlling the number of mixing drums, the amount of foamed concrete poured can be effectively controlled. By setting an upper connecting sleeve on the feed pipe, the powder spillage during the feeding process can be avoided. At the same time, as the connecting sleeve is raised, the top rod gradually discharges the sealing plug, ensuring convenient and smooth powder discharge. This effectively solves the problem of existing foamed concrete devices being too large and having a relatively limited range of applications. Multiple mixing drums are set up, and the material distribution mechanism feeds each mixing drum. The number of mixing drums can be selected according to the needs of the usage scenario. The structure is ingenious, convenient and practical.

[0016] (2) By setting a feeding chute on the feeding pipe and connecting the feeding chute to the hopper, the sealing plug can be prevented from slipping. By setting a feeding slider and feeding chute on the side of the sealing plug, the sliding direction of the sealing plug can be limited. At the same time, the pressure between the upper sleeve and the feeding pipe can also limit the lifting stroke of the push rod, preventing the push rod from pushing the lower slider to separate from the feeding chute. The setting of the discharge slope can discharge the powder accumulated in the feeding chute during the resetting of the sealing plug, thereby preventing the sealing plug from failing to completely seal the feeding pipe. By setting a positioning bottom hole at the bottom of the sealing plug and setting a magnetic block in the positioning bottom hole, the cooperation between the push rod and the positioning bottom hole can limit the upward movement direction of the push rod. At the same time, the magnetic attraction between the electromagnet and the magnet on the push rod can help the sealing plug to accurately reset, further ensuring the complete sealing of the hopper by the sealing plug.

[0017] (3) This invention sets two receiving components on the mounting frame. The discharge pipe below each receiving component is connected to the mixing box. When the concrete powder needs to be mixed in proportion, the powder can be fed through different feeding pipes and the feeding control valve can be used to control the feeding of the powder. At the same time, the operator can also control the amount of feeding through the scale plate on the receiving box, thereby achieving precise control of the amount of powder and accurate proportion. The mixing motor, mixing shaft and mixing blade can break up the powder clumps in the powder and mix different powders. The bottom telescopic rod ensures the stability of the mixing box during the process of raising and lowering the feeding pipe. It can also further limit the raising of the feeding pipe and the lowering of the discharge pipe, making it stable and practical.

[0018] (4) By setting two rows of mixing tanks in the inner chamber, the operator can choose to open the side doors on both sides according to the needs of the usage scenario, thereby adapting to the usage scenario. By setting the built-in foamer in the inner chamber, the on-site operator can add foaming agent according to the amount of concrete in the mixing tank to mix and stir, thereby preparing foamed concrete, which has good adjustability and applicability.

[0019] (5) The present invention provides an adjustment component on the outer wall of the adjustment component that can retract the pouring pipe. The pressure block is pressed against the second stop hook by the continuous force of the pressure spring. After the pouring pipe is pulled out, it is positioned by the continuous force of the torsion spring and the pressure of the first and second stop hooks. This ensures the smoothness of the pouring pipe during the process of being pulled out and used. At the same time, it can also prevent the pouring pipe from reversing and prevent the pouring pipe from retracting during use. When the pouring pipe is retracted, the operator can press the pressure block to disengage the first and second stop hooks and achieve the retraction of the pouring pipe under the action of the torsion spring. It is convenient and practical.

[0020] (6) The present invention provides a sealing rubber sheet on the top cover and a cross opening on the sealing rubber sheet. On the one hand, it can seal the mixing tank, and on the other hand, the cross opening can facilitate the smooth insertion of the discharge pipe or guide pipe into the mixing tank, which is efficient and convenient.

[0021] (7) The present invention provides a cleaning rod on the stirring shaft and a brush head on the cleaning rod. The brush head can scrape off the powder residue on the wall of the mixing tank, thereby ensuring the cleanliness of the mixing tank.

[0022] (8) This invention sets a rotating rod inside the inner chamber and rotates the mixing drum on the rotating rod. When the mobile vehicle moves uphill or downhill, or starts or brakes suddenly, the inertia generated is adjusted. When the mobile vehicle reaches the usage scenario, the mixing drum can be rotated by the rotating platform and the mixing drum can be extended by rotating the rotating rod through the third cylinder. This avoids the problem of limited inner chamber space and inconvenience for operators to take out the pouring pipe. At the same time, a stop block is set on the rotating rod. The stop block is detachably fixed in the support groove by the locking part. When there is too much residual material in the mixing drum or other powders need to be remixed, the operator can remove the stop block and take off the mixing drum to clean the inside of the mixing drum. This is efficient and convenient.

[0023] (9) The present invention sets up a rear compartment on the mobile vehicle to place a storage compartment, which stores some tools needed during the pouring process. The spare compartment is equipped with a construction vehicle. When the space of the usage environment is limited and the mobile vehicle cannot enter, the operator can take out the construction vehicle and inject the foamed concrete in the mixing bucket in the inner compartment into the construction vehicle for mixing. Then, the pouring can be carried out in the limited space of the usage environment through the pouring pipe on the construction vehicle, which is convenient and practical.

[0024] (10) This invention sets up multiple solar panels on the side door. The solar panels can charge the built-in power supply of the mobile vehicle. After the construction vehicle is recovered, the charging plug and charging port on the construction vehicle can be used to charge the construction vehicle in a timely manner. It is efficient and practical. Attached Figure Description

The pouring pipe 62 on the mixing tank 6 is fed with foaming agent through an external pipe and mixed with concrete. The formed foamed concrete is then discharged and poured.

[0054] When the receiving box 71 is not receiving or discharging material, each of the first cylinders 72 and the second cylinders 73 is not horizontal and is set at an acute angle to the mounting frame 56. When the receiving box 71 needs to be fed, each of the first cylinders 72 is inflated and started, and each of the second cylinders 73 does not work and rotates as the receiving box 71 is raised. When the upper connecting sleeve 76 on the feeding pipe 74 is pressed against the discharging pipe 42, the second cylinder 73 is still set at an acute angle to the mounting frame 56. The pressing of the upper connecting sleeve 76 and the discharging pipe 42 can also play the role of upward movement limit. Similarly, when the discharge pipe 75 moves down into the mixing tank 6, each of the second cylinders 73 is started, and each of the first cylinders 72 does not work and rotates as the receiving box 71 moves down.

[0055] The diameter of the upper connecting sleeve 76 is larger than the diameter of the feed pipe 42 and the feed pipe 74. A guide slope 761 is provided between the inner wall of the upper connecting sleeve 76 and the inner wall of the feed pipe 74. On the one hand, it can limit and press the connection between the upper connecting sleeve 76 and the feed pipe 42. On the other hand, it can also prevent the powder falling from the feed pipe 42 from remaining in the upper connecting sleeve 76.

[0056] The second movable frame 55 is equipped with an air pump, which is connected to the feed pipe 74 through a hose. On the one hand, it can assist the powder feeding when the receiving box 71 feeds the mixing tank 6. On the other hand, it can also completely blow out the residual powder in the feed pipe 74, the receiving box 71, and the discharge pipe 75.

[0057] The inner wall of the feeding pipe 42 is provided with a feeding groove 421 coaxially arranged with the feeding pipe 42. One end of each feeding groove 421 is located on the inner wall of the feeding pipe 42, and the other end of each feeding groove 421 extends along the axis of the feeding pipe 42 to communicate with the hopper 41. The side of the sealing plug 44 is provided with a feeding slider 441 adapted to each feeding groove 421. One end of each feeding slider 441 is located on the side of the sealing plug 44, and the other end of each feeding slider 441 extends along the axis of the feeding pipe 42 away from the hopper 41 to below the sealing plug 44. When each feeding slider 441 slides to the bottom of the feeding groove 421, the sealing plug 44 closes the feeding pipe 42. During the upward sliding process of each feeding slider 441, the sealing plug 44 disengages from the feeding pipe 42 and opens the feeding pipe 42 for feeding. The lower end of each feeding slider 441 A discharge ramp 444 is provided to remove residual powder in the discharge chute 421. The discharge ramp 444 extends obliquely from the surface of the discharge slider 441 away from the sealing plug 44 to the surface of the discharge slider 441 connected to the sealing plug 44. The discharge ramp 444 discharges the powder in the discharge chute 421 into the discharge pipe 42 as the sealing plug 44 slides down. The bottom of the sealing plug 44 is provided with a positioning bottom hole 442 into which the push rod 77 can extend. A magnetic block 443 is fixed in the positioning bottom hole 442. An electromagnet 771 is fixed at the upper end of the push rod 77. The push rod 77 pushes the sealing plug 44 open by the drive of each first cylinder 72 to the feed pipe 74. After receiving the material, the electromagnet 771 and the magnet cooperate, as well as the cooperation of the discharge slider 441 and the discharge chute 421, to press down the sealing plug 44 and close the discharge pipe 42.

[0058] The inner chamber 4 contains multiple hoppers 41 for holding different powders. A lifting cylinder 57 is fixedly mounted on the second movable frame 55. A rotary motor 58 is mounted on the telescopic end of the lifting cylinder 57. The mounting frame 56 is located at the output end of the rotary motor 58. Multiple connecting telescopic rods 551 are provided between the mounting frame 56 and the second movable frame 55. One end of each connecting telescopic rod 551 is fixed to the second movable frame 55. The mounting frame 56 has an annular groove perpendicular to the rotation axis of the mounting frame 56. The other end of each connecting telescopic rod 551 is provided with a slider, and each slider is slidably connected. The connecting telescopic rod 551, located within the annular groove, has one end slidably mounted on the mounting frame 56 via a slider and the annular groove. The mounting frame 56 has two opposing receiving assemblies 7, and each feed pipe 74 is equipped with a feed control valve 741. A mixing box 78 is located below the mounting frame 56. The discharge pipes 75 on each receiving assembly 7 are oppositely positioned and converge on both sides of the mixing box 78. A guide pipe 79, communicating with the mixing box 78, is located below the mixing box 78. A second control valve 791 is installed on the guide pipe 79. A mixing motor 781 is fixedly mounted on the mixing box 78. Inside the mixing box 78 is a mixing shaft 782 that can be rotated and positioned within the mixing box 78 under the drive of the mixing motor 781, and multiple mixing blades 783 circumferentially distributed along the axis of the mixing shaft 782. Multiple bottom telescopic rods 561 are provided between the mixing box 78 and the mounting frame 56. The fixed end of each bottom telescopic rod 561 is mounted on the mounting rod, and the telescopic end of each bottom telescopic rod 561 is mounted on the mixing box 78. Each receiving box 71 is provided with a graduated groove, and a receiving device is installed in the graduated groove. A transparent graduated plate 711 measures the powder in box 71. Each receiving box 71 extends into the corresponding hopper 41 to receive powder through the drive of the mounting frame 56 by the rotary motor 58 and the drive of the feed pipe 74 by the first cylinder 72. The powder in each receiving box 71 is fed into the mixing box 78 through the discharge pipe 75. Each mixing blade 783 disperses and mixes the powder through the drive of the mixing shaft 782 by the mixing motor 781. After the lifting cylinder 57 drives the guide pipe 79 to extend into the mixing tank 6, the second control valve 791 is opened to introduce the proportionally mixed powder into the mixing tank 6.

[0059] By setting two receiving components 7 on the mounting frame 56, the two receiving components 7 can receive and mix materials according to the usage requirements and mixing ratio of the application scenario. When feeding, the feeding pipes 74 on the two receiving components 7 can simultaneously enter different material bins 41 to pick up materials under the drive of each first motor 52, and control the feeding of the feeding control valve 741 according to the mixing ratio. The operator can confirm the feeding amount by observing the scale plate 711 on each receiving box 71. After all the receiving boxes 71 have been fed, both feeding control valves 741 are closed. Then the feeding pipe 74 is disconnected from the discharge pipe 42 of the material bin 41, the first control valve 751 on each discharge pipe 75 is opened, and the powder in each receiving box 71 falls into the mixing box 78. The powder in the mixing box 78 is dispersed and mixed by the mixing motor 781 driving the mixing shaft 782 and the mixing blades 783 on the mixing shaft 782.

[0060] If only one material receiving component 7 needs to be fed into the hopper 41, one of the receiving components 7 can be moved to the lower part of the hopper 41 by rotating the motor 58, and the other receiving component 7 can be moved to a position away from the hopper 41. This avoids the feeding pipe 74 located below the hopper 41 from colliding with the hopper 41 during the lifting and receiving process. Alternatively, both receiving components 7 can be moved to the lower part of the hopper 41. After each feeding pipe 74 extends into the discharge pipe 42 of the hopper 41, the feeding control valve 741 on the feeding pipe 74 that needs to be fed is opened to feed the material, and the feeding control valve 741 on the feeding pipe 74 that does not need to be fed is closed.

[0066] Each mixing drum 6 is suspended and rotated on each rotating rod 191 through the cooperation of each shaft block 63 and support groove 192. This is to accommodate the influence of the inertia generated by the mobile vehicle 1 when going uphill or downhill, or when the mobile vehicle 1 starts or brakes suddenly, on the mixing drum 6, and to prevent the mixing drum 6 from overturning during the movement of the mobile vehicle 1. After the mobile vehicle 1 moves to the designated construction site, the side door 2 on the mobile vehicle 1 opens, and each third cylinder 181 drives each rotating rod 191 to extend, which in turn drives each mixing drum 6 to extend. The operators at the construction site can pull the pouring pipe 62 on the corresponding mixing drum 6 to pour on the construction site. At the same time, after each mixing drum 6 is completed, if there is too much residual mixing material in the mixing drum 6 or new material needs to be mixed, the operators can remove the mixing drum 6 by disassembling the stop block 193, clean the mixing drum 6, and then reinstall it on the rotating rod 191 through the stop block 193.

[0068] Each side door 2 is equipped with multiple solar panels 21, and each solar panel 21 is electrically connected to the built-in power supply of the mobile vehicle 1. Each solar panel 21 is charged after each side door 2 is opened.

[0069] The working principle of the present invention is as follows: The controller on the mobile carrier 1 is electrically connected to each of the following components within the mobile carrier 1: feed control valve 741, first control valve 751, second control valve 791, first cylinder 72, second cylinder 73, third cylinder 181, first motor 52, second motor 54, rotary motor 58, stirring motor 64, mixing motor 781, material pump, defoaming pump, and electromagnet 771.

[0070] In the process of using this invention, each mixing tank 6 is first installed on each mixing support 19. The shaft blocks 63 at both ends of each mixing tank 6 are inserted into the corresponding support grooves 192. Each stop block 193 is inserted into the support groove 192 after the shaft block 63 enters the support groove 192 and is fixed in the support groove 192 by locking parts to prevent the shaft block 63 from coming out of the rotating rod 191. Then, the mixing tank 6 is reset by driving the rotating rod 191 through each third cylinder 181. The mixing tank 6 is suspended and rotated on the opposite rotating rod 191. Before the mobile carrier 1 needs to be transferred to the construction site to be poured, the mixing liquid can be injected into each mixing tank 6. Then, during the movement of the mobile carrier 1, the foam concrete is pre-mixed and pre-stirred according to the proportion and amount of foam concrete required by the construction site.

[0071] When concrete powder does not require proportioning, during the feeding process, the first motor 52 drives the first moving frame 53, and the second motor 54 drives the second moving frame 55, transferring the receiving assembly 7 on the mounting frame 56 to directly below the hopper 41. Then, the controller controls the first cylinder 72 to start, while the second cylinder 73 does not start. The first cylinder 72 drives the feeding pipe 74 to rise. During the rising process of the feeding pipe 74, as the upper connecting sleeve 76 presses against the lower material pipe 42, the push rod 77 extends into the positioning bottom hole 442 on the sealing plug 44. The controller controls... When electromagnet 771 is energized, the electromagnet 771 on the push rod 77 magnetically engages with the magnetic block 443 inside the positioning hole 442. After the upper connecting sleeve 76 presses against the feeding pipe 42, the push rod 77 pushes out the sealing plug 44. Then, the feeding pipe 42 connects with the feeding pipe 74, and the powder in the hopper 41 falls into the receiving box 71. After receiving, the controller starts the first cylinder 72 to reset the feeding pipe 74. During the reset process, the sealing plug 44 is pushed back in through the cooperation of the magnetic block 443 and the electromagnet 771 on the push rod 77. During the process, the discharge ramp 444 on the discharge slider 441 pushes the powder accumulated in the discharge chute 421 into the discharge pipe 42 as it slides down. After the sealing plug 44 seals the discharge pipe 42, the controller de-energizes the electromagnet 771, and the push rod 77 and the upper connecting sleeve 76 disengage from the discharge pipe 42. After the feed pipe 74 resets, the controller controls the first moving frame 53 and the second moving frame 55 to move, and transfers the receiving box 71 and the discharge pipe 75 below the receiving box 71 to the top of the corresponding mixing tank 6. The controller then activates the second cylinder 73. The discharge pipe 75 is driven into the mixing tank 6. During the process of the discharge pipe 75 entering the mixing tank 6, the discharge pipe 42 passes through the cross opening 615 of the sealing rubber sheet 614 on the upper cover 61 and enters the mixing tank 6. Then, the first control valve 751 on the discharge pipe 75 is opened to introduce the powder in the receiving box 71 into the mixing tank 6. The stirring motor 64 in the mixing tank 6 drives the stirring shaft 65 and the stirring blade 66 to stir the stirring liquid and powder in the mixing tank 6. After the discharge is completed, the discharge pipe 75 is reset by the drive of the second cylinder 73 and the first control valve 751 is closed.

[0072] When concrete powder requires the mixing of multiple powders before stirring, two mixing components are installed on the mounting frame 56. The discharge pipes 75 below the two mixing components converge on the mixing box 78. During the feeding process, the first motor 52 drives the first moving frame 53, and the second motor 54 drives the second moving frame 55, moving the two receiving components 7 on the mounting frame 56 directly below the two hoppers 41. The controller lifts each feeding pipe 74 and opens each feeding control valve 741, allowing the powder in each hopper 41 to fall into the corresponding receiving box 71. Inside, each feed pipe 74 is reset, the feed control valve 741 is closed, the controller controls the first moving frame 53 and the second moving frame 55 to move the guide pipe 79 to the top of the corresponding mixing tank 6, each first control valve 751 and the mixing motor 781 are opened, the powder in each receiving box 71 falls into the mixing box 78, and the powder is dispersed and stirred by the mixing shaft 782 driven by the mixing motor 781. Then, after the guide pipe 79 extends into the mixing tank 6, the second control is opened to introduce the mixed powder into the mixing tank 6 for stirring. The guide pipe 79 is reset after the feeding is completed.

[0073] When the mobile vehicle 1 arrives at the designated usage scenario, the side door 2 on the mobile vehicle 1 opens, and each rotating platform 18 drives each mixing bracket 19 to rotate. Then, according to the usage requirements of the construction site, the number of mixing drums 6 is selected, and each third cylinder 181 drives each rotating rod 191 to rotate and extend the corresponding mixing drum 6. The operator can then introduce foaming agent into each mixing drum 6 through the pipe and continue mixing. After that, the operator can pull out the pouring pipe 62 and pour on site.

[0074] This invention effectively solves the problem of limited and fixed application scenarios in existing technologies. At the same time, the setting of multiple mixing tanks 6 also solves the problem of uncontrollable preparation volume in existing technologies. By setting up a mobile carrier 1, it can be applied to various different pouring scenarios. At the same time, by setting up multiple mixing tanks 6, an appropriate amount of foamed concrete can be prepared according to the needs of on-site pouring. It has good adjustability and strong applicability, and its structure is ingenious, convenient and practical.

[0075] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention.
