[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-6, the present invention provides a technical solution: including a mixing tank body 1, the mixing tank body 1 is an existing technology, and a mixing device is rotatably connected inside to mix the stored concrete. A base 2 is fixedly connected to the bottom of the mixing tank body 1. The base 2 is composed of two support plates and several support columns. The two ends of the support columns are respectively fixedly connected to the two support plates. The base 2 is arranged on the ground to support the mixing tank body 1. A telescopic plate 4 is slidably connected to the upper surface of the base 2 through four guide rods 6. The guide rods 6 are angle steels. The telescopic plate 4 is arranged between the four guide rods 6. The telescopic plate 4 is composed of two connecting plates. One of the connecting plates extends into the other connecting plate and is slidably connected thereto. A storage tank 5 is rotatably connected to the upper surface of the telescopic plate 4. When the storage tank 5 is tilted, the telescopic plate 4 can extend accordingly. The upper surface of the end of the telescopic plate 4 away from the mixing tank body 1 is connected to the storage tank 5, so that when the storage tank 5 is tilted, the telescopic plate 4 realizes telescoping. A telescopic device 3 is arranged between the telescopic plate 4 and the base 2. The telescopic device 3 includes a reciprocating lead screw 31. The reciprocating lead screw 31 is an existing technology. When the reciprocating lead screw 31 works, it drives the storage tank 5 to move upward. The reciprocating lead screw 31 includes a lifting rod 311 and a fixed rod 312 that are threadedly connected to each other. The inner wall of the fixed rod 312 is provided with a double-thread. One end of the lifting rod 311 extends into the interior of the fixed rod 312 and is threadedly connected thereto through the double-thread. When the fixed rod 312 rotates, it drives the lifting rod 311 to reciprocate up and down on the fixed rod 312, so that the storage tank 5 rises and after pouring out the internally filled concrete expansion agent, it drives the storage tank 5 to move downward, realizing the reciprocating use of the storage tank 5. A claw 32 is slidably connected to the periphery of the reciprocating lead screw 31. A transmission shaft 71 that cooperates with the claw 32 is rotatably connected to the bottom end of the reciprocating lead screw 31. The claw 32 clasps the transmission shaft 71 to fix the fixed rod 312 and the transmission shaft 71 together. When the transmission shaft 71 rotates, it drives the fixed rod 312 to rotate, so that the storage tank 5 realizes lifting and moving. When the claw 32 releases the transmission shaft 71, the transmission shaft 71 idles and the reciprocating lead screw 31 stops working. A guide plate 11 is fixedly connected to the upper surface of the base 2. One side of the guide plate 11 is fixedly connected to the mixing tank body 1. The other side of the guide plate 11 is provided with a guide groove 111 that cooperates with the storage tank 5. When the storage tank 5 moves upward, the periphery of the top end abuts against the guide groove 111, so that the storage tank 5 can realize vertical upward movement. When the top end of the storage tank 5 moves out of the guide groove 111, the storage tank 5 continues to move upward, so that while the storage tank 5 gradually tilts, the tilted end extends directly above the mixing tank body 1, so that the concrete expansion agent in the storage tank 5 is poured into the mixing tank body 1. A transmission device 7 is arranged inside the base 2. The transmission device 7 includes a gear set and a motor 72. The motor 72 is an existing technology, and the model can be selected as Y80M2-2. The motor 72 provides power for the rotation of the gear set. The motor 72 is fixedly connected to the base 2. The gear set includes a first gear 73, a third gear 75, and a second gear 74 that are sequentially meshed with each other. The first gear 73, the third gear 75, and the second gear 74 are all rotatably connected to the base 2.The output shaft of the motor 72 is fixedly connected to the third gear 75. The third gear 75 drives the first gear 73 and the second gear 74 to rotate. The bottom end of the transmission shaft 71 extends into the interior of the base 2 and is fixedly connected to the first gear 73. The first gear 73 drives the transmission shaft 71 to rotate. The second gear is connected to the stirring device in the stirring tank body 1 and drives the stirring device to work. Two T-shaped blocks 41 are rotatably connected to both sides of the telescopic plate 4. T-shaped sliding grooves matching with the T-shaped blocks 41 are formed on one side of the four guide rods 6. The telescopic plate 4 slides on the guide rods 6 through the cooperation of the T-shaped blocks 41 and the T-shaped sliding grooves. The telescopic plate 4 is rotatably connected to the reciprocating lead screw 31, avoiding the T-shaped blocks 41 interfering with the inclination of the telescopic plate 4 through the T-shaped sliding grooves when the telescopic plate 4 inclines. Two third bosses 42 are fixedly connected to the lower surface of the side of the telescopic plate 4 away from the stirring tank body 1. The circumference of the lifting rod 311 is rotatably connected to the two third bosses 42 through a rotating shaft, so that when the reciprocating lead screw 31 rises and the storage tank 5 inclines, the storage tank 5 can be tilted towards the direction of the stirring tank body 1. The claw 32 includes a moving shaft 321. The moving shaft 321 is sleeved on the circumference of the fixed rod 312 and is slidably connected thereto. Baffles 322 are fixedly connected to both the upper and lower ends of the moving shaft 321. A plurality of connecting rods 324 are rotatably connected to the lower surface of the baffle 322 at the bottom end of the moving shaft 321 through a plurality of second bosses 323. The end of the connecting rod 324 away from the second boss 323 is rotatably connected to an arc-shaped claw 325. A plurality of first bosses 313 are fixedly connected to the circumference of the fixed rod 312. A limiting groove 3131 is formed at the end of the first boss 313 away from the fixed rod 312. Both sides of the arc-shaped claw 325 are rotatably connected to the limiting groove 3131 through a rotating shaft. When the moving shaft 321 moves upward, the arc-shaped claw 325 is driven by the connecting rod 324 to rotate on the first boss 313 to grip the transmission shaft 71. A lever 33 is arranged on the circumference of the moving shaft 321. The lever 33 includes a cross bar 331 and a bushing 332 which are rotatably connected to each other. The bushing 332 is sleeved on the circumference of the moving shaft 321 and is rotatably connected thereto. A thrust ball bearing is arranged between the bushing 332 and the baffle 322 at the top end of the moving shaft 321 to reduce the friction between the bushing 332 and the baffle 322. A support rod 8 fixedly connected to the base 2 is arranged on the lower surface of the cross bar 331. Both sides of the cross bar 331 are rotatably connected to the support rod 8 through a rotating shaft. When the end of the cross bar 331 away from the reciprocating lead screw 31 is pressed downward, the moving shaft 321 is driven to move upward through the bushing 332. A spring 34 is arranged on the circumference of the fixed rod 312. When the spring 34 is in its normal state, the claw 32 releases the transmission shaft 71. The two ends of the spring 34 are respectively fixedly connected to the first boss 313 and the baffle 322. When the cross bar 331 is moved upward and the bushing 332 is separated from the baffle 322, the spring 34 drives the moving shaft 321 to move downward to reset, thereby driving the arc-shaped claw 325 to release the transmission shaft 71.,

[0023] In use, simply start the motor 72. The motor 72 drives the first gear 73 and the second gear 74 to rotate through the third gear 75. The second gear 74 drives the stirring device in the stirring tank body 1 to operate. Subsequently, pour the concrete expansion agent to be used into the storage tank 5 according to the required dosage. Press down the end of the cross bar 331, so that the other end of the cross bar 331 tilts up to drive the bushing 332 to move upward. The baffle 322 at the top of the moving shaft 321 is used for limiting to drive the moving shaft 321 to move upward, so that the baffle 322 at the bottom end of the moving shaft 321 moves upward. The arc claw 325 is driven by the connecting rod 324 to rotate on the first boss 313 to tightly grip the transmission shaft 71. The first gear 73 drives the transmission shaft 71 to rotate. The fixed rod 312 is driven to rotate by the clamped claw 32, so as to drive the lifting rod 311 to rise. The storage tank 5 is driven to move upward by the telescopic plate 4. When the top end of the storage tank 5 moves out of the guide plate 11, it tilts, so that the internal concrete expansion agent is poured into the stirring tank body 1. The fixed rod 312 continues to rotate, and the lifting rod 311 is driven to move downward through the internal reciprocating thread until the lifting rod 311 descends to the lowest position, then lift the cross bar 331, and the spring 34 drives the arc claw 325 to release the transmission shaft 71.
