[0057] The blocking block 61 abuts against the limiting block 7 . Since the top surface of the limiting block 7 tilts upward from one end close to the transport pipe 32 to the other end, the blocking block 61 becomes tilted, which facilitates the concrete to flow into the transport pipe 32 .

[0058] Reference Figure 1 and Figure 6 The base 1 is fixedly connected with a bracket 13. The base 1 is connected with a water spray assembly 8, and the water spray assembly 8 includes a water tank 81, a water pump 82, a water supply pipe 83, a branch pipe 84 and a nozzle 85. The water tank 81 is fixedly connected with the base 1, and a water inlet hole is provided at the top of the water tank 81. The water pump 82 is fixedly connected with the top of the water tank 81, and the water inlet end of the water pump 82 is connected with the inside of the water tank 81, and the water outlet end is connected with the water supply pipe 83. The water supply pipe 83 is fixedly connected with the bracket 13, and the end of the water supply pipe 83 away from the water pump 82 is located above the tank body 2, and the end of the water supply pipe 83 away from the water pump 82 is closed.

[0059] When the inside of the tank body 2 needs to be cleaned, the water pump 82 is started, and the water pump 82 pumps water out of the water tank 81 and sends it to the water supply pipe 83.

[0060] Reference Figure 7 and Figure 8 A through hole 233 is vertically opened on the top of the tank cover 23, and there are four through holes 233. Four branch pipes 84 are vertically arranged, and the four branch pipes 84 correspond to the four through holes 233 one by one, and the four branch pipes 84 are inserted into the four through holes 233. The top of the branch pipe 84 is connected to the water supply pipe 83. Four nozzles 85 are arranged, and the four nozzles 85 correspond to the four branch pipes 84 one by one. The spray holes of the nozzles 85 face the inside of the tank body 2.

[0061] The water supply pipe 83 delivers water to the branch pipe 84, and the water in the branch pipe 84 is sprayed into the interior of the tank body 2 by the nozzle 85. The water sprayed by multiple nozzles 85 cleans the tank body 2 in all directions, and then the water is released by the unloading component 3, which can also clean the unloading component 3, saving time and effort.

[0062] Reference Figure 8 The tank cover 23 is connected with a shielding device 9, and the shielding device 9 is provided with four groups, and the four groups of shielding devices 9 correspond to the four through holes 233 one by one. The shielding device 9 includes a baffle 91, a threaded rod 92, a gear 93 and a rack 94. The tank cover 23 is horizontally provided with a slide groove 234, and the slide groove 234 matches the baffle 91. There are four slide grooves 234, and the four slide grooves 234 correspond to the four through holes 233 one by one. The slide grooves 234 are connected with the corresponding through holes 233.

[0063] Reference Figure 8 The threaded rod 92 passes through the through hole 233 and the slide groove 234, the length direction of the threaded rod 92 is parallel to the slide groove 234, and the threaded rod 92 is rotatably connected to the tank body 2. The baffle plate 91 is sleeved on the threaded rod 92 and threadedly connected to the threaded rod 92, and the baffle plate 91 is slidably abutted against the tank body 2. When the baffle plate 91 is located in the through hole 233, the baffle plate 91 isolates the nozzle 85 from the inside of the tank body 2.

[0064] Reference Figure 8 A movable groove 235 is provided at the bottom of the tank body 2, the threaded rod 92 passes through the tank body 2 and extends into the movable groove 235, the gear 93 is sleeved on the threaded rod 92 and fixedly connected to the threaded rod 92, one end of the rack 94 is connected to the second tank body 22, and the other end extends into the movable groove 235, and the rack 94 is meshed with the gear 93.

[0065] When the tank body 2 does not need to be cleaned, the baffle 91 blocks the nozzle 85 to reduce the occurrence of concrete in the tank body 2 adhering to the nozzle 85. When the tank body 2 needs to be cleaned, the driving cylinder 231 is started, and the driving cylinder 231 drives the tank cover 23 to move up, and the tank cover 23 drives the threaded rod 92, the gear 93, and the baffle 91 to move up synchronously. Since the rack 94 is meshed with the gear 93, the gear 93 rotates during the upward movement, and the rotation of the gear 93 drives the threaded rod 92 to rotate, and the rotation of the thread drives the baffle 91 to slide, and the baffle 91 slides into the slide groove 234, and the tank cover 23 continues to move up until the nozzle 85 protrudes from the tank cover 23. At this time, the tank cover 23 is still connected to the second tank body 22, and the water pump 82 is started again to make the nozzle 85 spray water to achieve the cleaning of the tank body 2.

[0066] The operating principle of the present application is as follows: when it is necessary to pour concrete in a small area, the staff feeds the concrete into the tank body 2 through the feeding pipe 232 and starts the stirring motor 41 at the same time. The stirring motor 41 drives the driving rod 42 to rotate, and the driving rod 42 drives the stirring blades 44 and the first scraper 432 to rotate. The stirring blades 44 stir the concrete in the tank body 2 to make the concrete evenly mixed and reduce the possibility of concrete coagulation; the first scraper 432 drives the second scraper 433 to move, the first scraper 432 scrapes the inner wall of the second tank body 22, and the second scraper 433 scrapes the inner wall of the first tank body 21, thereby reducing the possibility of concrete adhering to the first tank body 21 and causing increased costs.

[0067] At the same time, the driving rod 42 drives the rotating shaft 45 to move, the rotating shaft 45 drives the fixing frame 46 to rotate, and the rotating shaft 45 drives the spiral blade 5 to rotate. When the blocking block 61 blocks the feed opening of the tank body 2, the spiral blade 5 is located in the tank body 2, and the spiral blade 5 stirs the concrete.

[0068] When it is necessary to connect the feed pipe 31 and the tank body 2, the blocking cylinder 63 is started, the blocking cylinder 63 drives the connecting frame 625 to move downward, the connecting frame 625 drives the shaft 623 to move, the shaft 623 drives the first protrusion 621 and the second protrusion 622 to move downward, the first protrusion 621 and the second protrusion 622 drive the blocking block 61 to move downward until the blocking block 61 abuts against the limit block 7. At this time, the spiral blade 5 is located in the feed pipe 31, and the spiral blade 5 transports the concrete in the tank body 2 to the transport pipe 32, reducing the possibility of concrete blocking in the feed pipe 31. The feed motor 34 is started, and the feed motor 34 drives the auger 35 to rotate, and the auger 35 transports the concrete entering the transport pipe 32 from one end of the feed pipe 31 to one end of the discharge pipe 33, and discharges it from the discharge pipe 33, reducing the possibility of concrete blocking in the transport pipe 32.

[0069] When the tank body 2 does not need to be cleaned, the baffle 91 shields the nozzle 85 to reduce the occurrence of concrete in the tank body 2 adhering to the nozzle 85, thereby reducing the possibility of concrete blocking the nozzle 85. When the inside of the tank body 2 needs to be cleaned, all the concrete in the tank body 2 is released, and the driving cylinder 231 is started. The driving cylinder 231 drives the tank cover 23 to move up, and the tank cover 23 drives the threaded rod 92, the gear 93, and the baffle 91 to move up synchronously. Since the rack 94 is meshed with the gear 93, the gear 93 rotates during the upward movement, the gear 93 drives the threaded rod 92 to rotate, and the threaded rod 92 drives the baffle 91 to slide. The baffle 91 slides completely into the slide groove 234, and the tank cover 23 continues to move up until the nozzle 85 protrudes from the tank cover 23. At this time, the tank cover 23 is still connected to the second tank body 22. Then start the water pump 82, the water pump 82 pumps water from the water tank 81, and then the water is sent to the branch pipe 84 by the water delivery pipe 83, and the water in the branch pipe 84 is sprayed to the inside of the tank body 2 by the nozzle 85, and the water sprayed by the multiple nozzles 85 cleans the tank body 2 in all directions, and then the water is released by the material discharge assembly 3, which can also clean the material discharge assembly 3. After the cleaning is completed, turn off the water pump 82 to reset the tank cover 23.
