[0022] Specifically, by providing a mixing component 3, a fluidized bed 4 and an injection component 5, the concrete is always kept in a fluidized state, which significantly improves the discharge speed and efficiency. Compared with the traditional air pressure push type discharge device, the scheme requires lower compressed air pressure, less energy consumption, and greatly reduces the operating cost. The dust and noise generated during the discharge process are significantly reduced, which improves the working environment and protects the health of workers.

The bottom end of the vertical rod 32 is rotatably connected to the inside of the tank body 1, and two stirring rods 33 of different lengths and staggered arrangement are connected to the side wall of the vertical rod 32.
[0024] Specifically, concrete enters the mixing chamber 2 through the feed hopper 11, and the motor 31 drives the vertical rod 32 to rotate, so that the vertical rod 32 drives the two stirring rods 33 on the rod to rotate. The diameter of one stirring rod 33 is set to 800 mm, and the diameter of the other stirring rod 33 is set to 600 mm. The two stirring rods 33 are staggered and used in conjunction with each other to increase the stirring effect.

[0026] Specifically, the rotation of the vertical rod 32 drives the two scrapers 34 to rotate synchronously, so that the scrapers 34 rotate in contact with the inner wall of the mixing chamber 2, thereby scraping off the concrete adhering to the inner wall of the mixing chamber 2, reducing the adhesion of the concrete and further speeding up the discharge of the concrete.
[0027] Please refer to Figure 2 , Figure 3 , Figure 4 , the fluidized bed 4 includes an annular plate 41, a breathable net 42 and a slide bar 43; A plurality of slide bars 43 are equidistantly installed on the inner wall of the tank body 1 in the circumferential direction, and an annular plate 41 is slidably connected to the outer walls of the plurality of slide bars 43 , and three air-permeable nets 42 are equidistantly connected to the inner wall of the annular plate 41 .

[0031] The air inlet pipe 52 is externally connected to an air compressor for supplying air to the inside of the air inlet pipe 52 . Meanwhile, a flow meter is installed at the port of the air inlet pipe 52 for monitoring the flow of compressed air to ensure the stability and safety of the discharge process.
[0032] Specifically, air is taken in through the air inlet pipe 52 into the air inlet groove 53 opened in the upright rod 32, and the gas is ejected through the air supply branch pipe 54. The gas enters the concrete through the air permeable mesh 42 to form tiny bubbles. These bubbles play a stirring role in the concrete, which helps to break up the agglomeration of particles in the concrete and make it more evenly dispersed. The rising and bursting process of the bubbles will also drive the movement of the concrete particles, further improving the fluidity of the concrete. The setting of the one-way valve can effectively prevent the concrete from entering the air supply branch pipe 54.
[0033] Please refer to Figure 2 , Figure 3 , Figure 5 , the reciprocating mechanism 6 includes a crossbar 61, a bevel gear assembly 62, a cam 63, a movable wheel 64, a movable rod 65, a notch 66 and a connecting plate 67; A cross bar 61 is rotatably connected inside the tank body 1, and a bevel gear assembly 62 is installed on the side wall of the lower end of the vertical rod 32.

Each movable rod 65 is slidably connected to the outer wall of the tank body 1. Two notches 66 are symmetrically opened inside the tank body 1. A connecting plate 67 is slidably connected inside each notch 66. The side wall of each connecting plate 67 is connected to the outer wall of the annular plate 41. The bottom end of each connecting plate 67 is connected to the top of the movable rod 65.
[0034] The bevel gear assembly 62 includes a first bevel gear and a second bevel gear. The first bevel gear is connected to the lower end of the vertical rod 32 . The side wall of the first bevel gear is meshed with the second bevel gear. The second bevel gear is connected to the outer wall of the crossbar 61 .
[0035] Specifically, the vertical rod 32 drives the first bevel gear to rotate, and the second bevel gear is driven to rotate through the first bevel gear, so that the second bevel gear drives the cross bar 61 to rotate, and the cam 63 is driven to rotate through the cross bar 61, so that the cam 63 squeezes the movable wheel 64, and the movable wheel 64 drives the movable rod 65 to slide on the tank body 1, and the movable wheel 64 is always in contact with the outer wall of the cam 63. The movable wheel 64 can achieve reciprocating movement under the action of the cam 63, and the movable rod 65 is lifted and lowered while driving the connecting plate 67 to slide in the groove 66. The connecting plate 67 drives the annular plate 41 to slide on the slide rod 43 while sliding, thereby driving the concrete on the air permeable net 42 to reciprocate up and down, thereby having a vibrating and screening effect on the concrete, accelerating the elimination of bubbles inside the concrete, further improving the fluidity of the concrete, and improving the subsequent discharging efficiency.
[0036] Please refer to Figure 2 , Figure 5 , Figure 6The water spray mechanism 8 includes a water inlet tank 81, an atomizing nozzle 82 and a water inlet assembly 83; Two water inlet grooves 81 are provided inside the tank body 1 , and an atomizing nozzle 82 is installed at one end of each water inlet groove 81 facing the discharge port 12 .
[0037] Specifically, the water in the water storage chamber 7 is sent into the water inlet tank 81 through the water inlet assembly 83, and the water is finally sprayed out through the atomizing nozzle 82. The temperature and viscosity of the concrete are reduced by spraying water, and the discharge speed is further increased.
[0038] Please refer to Figure 2 , Figure 6 The water inlet assembly 83 includes a water inlet tank 831, a filling port 832, a lower pressure plate 833 and a connecting rod 834; Two water inlet tanks 831 are installed inside the water storage chamber 7, and two filling ports 832 are symmetrically installed inside each water inlet tank 831. A one-way valve is connected inside each filling port 832. Any filling port 832 is connected to one end close to the water inlet groove 81. A lower pressure plate 833 is slidably connected inside each water inlet tank 831, and a connecting rod 834 is connected to the top of each lower pressure plate 833. The top of each connecting rod 834 is connected to the bottom of the connecting plate 67, and the rod part of each connecting rod 834 is slidably connected inside the water storage chamber 7.
[0039] Please refer to Figure 6 The one-way valve near one end of the water inlet tank 81 only supplies water into the water inlet tank 81, and the other one-way valve only supplies water into the water inlet tank 831.
[0040] Specifically, when the connecting plate 67 moves downward, it will drive the lower pressure plate 833 connected to the bottom end of the connecting rod 834 to move downward synchronously, so that the water inside the water inlet tank 831 can be pushed into the filling port 832 near one end of the water inlet tank 81. At this time, the inside of the water inlet tank 831 is in a negative pressure state due to the discharge of air and liquid. When the connecting plate 67 moves upward, it will drive the lower pressure plate 833 connected to the bottom end of the connecting rod 834 to move upward synchronously, and the water inside the water storage chamber 7 will flow into the water inlet tank 831 through the other filling port 832, thereby completing the water adding work to the inside of the water inlet tank 81.
[0041] Please refer to Figure 1 A water inlet and a water outlet are arranged on the upper and lower sides of the water storage chamber 7, and control valves are arranged inside the water inlet and the water outlet.
[0042] Specifically, by providing a water inlet and a water outlet on the water storage chamber 7 , it is convenient for the staff to add and discharge water inside the water storage chamber 7 .
[0043] Working principle: Concrete enters the mixing chamber 2 through the feed hopper 11, and the motor 31 drives the vertical rod 32 to rotate, so that the vertical rod 32 drives the two stirring rods 33 on the rod to rotate. The diameter of one stirring rod 33 is set to 800mm, and the diameter of the other stirring rod 33 is set to 600mm. The two stirring rods 33 are staggered and used in conjunction with each other to increase the mixing effect. When the vertical rod 32 rotates, the two scrapers 34 are driven to rotate synchronously, so that the scrapers 34 rotate in contact with the inner wall of the mixing chamber 2, so that the concrete adhering to the inner wall of the mixing chamber 2 can be scraped off, the adhesion of the concrete is reduced, and the discharge of the concrete is further accelerated; After being stirred by the mixing assembly 3, the concrete falls onto the fluidized bed 4. A gap of 5 cm is left between each layer of the air permeable mesh 42, and the air permeable mesh is made of stainless steel, which ensures good air permeability and durability. The pressure sensor can monitor the air pressure change in the fluidized bed 4 in real time. The air inlet pipe 52 is used to inlet air into the air inlet groove 53 provided in the upright rod 32, so that the gas is ejected through the air supply branch pipe 54. The gas enters the concrete through the air permeable mesh 42 to form tiny bubbles. These bubbles play a stirring role in the concrete, which helps to break the agglomeration of particles in the concrete and make it more evenly dispersed. The rising and rupture process of the bubbles will also drive the movement of the concrete particles, further improving the fluidity of the concrete. The setting of the one-way valve can effectively prevent the concrete from entering the air supply branch pipe 54. The vertical rod 32 drives the first bevel gear to rotate, and the second bevel gear is driven to rotate through the first bevel gear, so that the second bevel gear drives the cross bar 61 to rotate, and the cam 63 is driven to rotate through the cross bar 61, so that the cam 63 squeezes the movable wheel 64, and the movable wheel 64 drives the movable rod 65 to slide on the tank body 1, and the movable wheel 64 is always in contact with the outer wall of the cam 63. The movable wheel 64 can achieve reciprocating movement under the action of the cam 63. The movable rod 65 is lifted and lowered while driving the connecting plate 67 to slide in the notch 66. The connecting plate 67 drives the annular plate 41 to slide on the slide rod 43 while sliding, thereby driving the concrete on the air permeable net 42 to reciprocate up and down, thereby achieving a vibrating and screening effect on the concrete, accelerating the elimination of bubbles inside the concrete, further improving the fluidity of the concrete, and improving the subsequent discharging efficiency; When the connecting plate 67 moves downward, it will drive the lower pressure plate 833 connected to the bottom end of the connecting rod 834 to move downward synchronously, so that the water inside the water inlet tank 831 can be pushed into the filling port 832 near one end of the water inlet trough 81. At this time, the inside of the water inlet tank 831 is in a negative pressure state due to the discharge of air and liquid. When the connecting plate 67 moves upward, it will drive the lower pressure plate 833 connected to the bottom end of the connecting rod 834 to move upward synchronously, and the water inside the water storage chamber 7 will flow into the water inlet tank 831 through another filling port 832, thereby completing the water filling work inside the water inlet trough 81, and the water inside the water storage chamber 7 is sent into the water inlet trough 81 through the water inlet assembly 83. The water is finally sprayed out through the atomizing nozzle 82, and the temperature and viscosity of the concrete are reduced by spraying water, thereby further increasing the discharge speed.
