[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention pours the concrete material after mixing into the interior of the curved cylinder, and the concrete material enters the interior of the pouring pipe through the curved cylinder, and the concrete material is poured to the construction site through the pouring pipe. When the concrete material enters the interior of the curved cylinder, it is blocked by the setting of the special-shaped blocking plate, and the flow rate of the concrete material is reduced to prevent the impact force generated when a large amount of concrete material is transported from being too large, which causes the concrete material to splash when it is distributed, thereby improving the stability of material transportation. Under the pressure of the concrete material, the special-shaped blocking plate rotates around the concave shell. During the downward rotation of the special-shaped blocking plate, it contacts the rotating ball and squeezes the rotating ball. Because the sliding frame slides on the inner wall of the curved cylinder, when the rotating ball is squeezed, the rotating ball drives the sliding frame to move. The sliding frame drives the sliding plate to move, and the sliding plate slides on the inner wall of the fixed shell to push the water inside the fixed shell and the annular shell, and the water flows through the annular shell into the interior of the drain pipe, and the water flows through the drain pipe into the interior of the annular water spray box, and the water flows downward on the annular zigzag plate in the annular water spray box, so that the annular zigzag plate moves downward inside the annular water spray box, and when the annular zigzag plate moves to the bottom of the inner cavity of the annular water spray box, one side of the annular zigzag plate no longer blocks the annular water spray box, and the water flows through the annular water spray box to spray water to the connection between the concave shell and the special-shaped baffle plate, so that the bent drum cleans the connection between the concave shell and the special-shaped baffle plate when conveying concrete material, to prevent the connection between the concave shell and the special-shaped baffle plate from being blocked by concrete material, thereby improving the operating stability of the device.

[0017] (2) According to the present invention, when the annular zigzag plate descends, the annular zigzag plate drives the extrusion ring to move downward. During the descending process, the extrusion ring can press down one side of the special-shaped blocking plate, thereby further improving the fitting effect between the special-shaped blocking plate and the inner wall of the curved tube. When the concrete material is no longer transported, the annular zigzag plate is elastically deformed by the tension spring, and the tension spring drives the annular zigzag plate to move upward on the inner wall of the annular water spray box. During the upward movement of the annular zigzag plate, the opening of the annular water spray box can be blocked, thereby preventing the water flow inside the annular shell from entering the interior of the curved tube, thereby reducing the consumption of water resources.

[0018] (3) In the present invention, when the sliding plate moves, the sliding plate drives the flexible rotating rod to move. The flexible rotating rod drives the sliding ring to move vertically downward along the inner wall of the annular shell due to the limitation of the annular shell. The sliding ring drives the connecting frame to descend. The connecting frame drives the toothed plate frame to descend. During the descending process, the toothed plate frame will mesh with the side wall of the first bevel gear, so that the first bevel gear rotates around the cross bar. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the gear ring to rotate. During the rotation of the gear ring, the connecting block is driven to rotate. During the rotation of the connecting block, the connecting block comes into contact with the outer wall of the casting pipe, thereby scraping off the concrete particles adhered to the outer wall of the casting pipe, preventing the concrete particles from adhering to the outer wall of the casting pipe for a long time and causing the concrete to harden, thereby affecting the subsequent scraping work of the casting pipe.

[0019] (4) According to the present invention, when the tooth plate frame is in the process of descending, the tooth plate frame drives the vertical rod to descend, and the vertical rod drives the first ring plate to descend. During the process of the first ring plate descending, the outer wall bottom of the casting pipe can be scraped and cleaned, thereby further improving the working stability of the casting pipe. In addition, the first ring plate drives the round rod frame to descend, and the round rod frame drives the second ring plate to descend. During the process of the second ring plate descending, it will come into contact with the top of the fixed ring, so that the fixed ring is pressed downward, and the fixed ring drives the casting pipe to be pressed downward, thereby causing the casting pipe to stretch downward, thereby preventing the casting pipe from deforming and bending during the process of the cleaning plate scraping the casting pipe, thereby improving the scraping effect of the cleaning plate on the casting pipe.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figure 1 - Fig. 9As shown, the present invention is a concrete distribution and pouring device for building construction engineering, comprising a curved cylinder 1, the bottom end of the curved cylinder 1 is connected to a pouring pipe 2, the bottom end outer wall of the pouring pipe 2 is fixedly connected to a fixing ring 3, the concrete material after mixing is poured into the interior of the curved cylinder 1, the concrete material enters the interior of the pouring pipe 2 through the curved cylinder 1, and the concrete material is distributed and poured to the construction site through the pouring pipe 2, and also includes;

[0035] The material distribution and pouring mechanism 4 includes four concave shells 41 fixedly connected to the inner wall of the curved cylinder 1. One side of the inner wall of the concave shell 41 is rotatably connected with a special-shaped blocking plate 42. When the concrete material enters the curved cylinder 1, it is blocked by the setting of the special-shaped blocking plate 42, and the circulation speed of the concrete material is reduced to prevent the excessive impact force generated when a large amount of concrete material is transported, which causes the concrete material to splash when distributed, thereby improving the stability of material transportation. Four sliding frames 43 are respectively penetrated and slidably connected to the inner wall of the curved cylinder 1 close to the concave shell 41. A rotating ball 44 is rotatably connected to the side wall of one end of the sliding frame 43. The setting of the rotating ball 44 can prevent the special-shaped blocking plate 42 from getting stuck during the downward pressing process. The rotating ball 44 is set inside the curved cylinder 1, and a moving component 45 is set on the outer wall of the curved cylinder 1.

[0036] The moving assembly 45 includes four fixed shells 451 fixedly connected to the outer wall of the bending cylinder 1. The end of the sliding frame 43 away from the rotating ball 44 is fixedly connected to a sliding plate 453. The outer wall of the sliding plate 453 is slidably connected to the inner wall of the fixed shell 451. The end of the fixed shell 451 away from the bending cylinder 1 is connected to an annular shell 452. The annular shell 452 is provided with a spring 454 fixedly connected to one side of the sliding plate 453. One end of the spring 454 is fixedly connected to the outer wall of one side of the bending cylinder 1.

[0037] The outer wall of the annular shell 452 is provided with a stabilizing component 46, which includes four drainage pipes 461 connected around the outer wall of the annular shell 452. The inner wall of the bent cylinder 1 close to the fixed shell 451 is fixedly connected with an annular water spray box 462, and one end of the drainage pipe 461 away from the annular shell 452 is connected to the inner cavity of the annular water spray box 462.

[0038] A tension spring 463 is fixedly connected to the top of the inner cavity of the annular water spray box 462, and one end of the tension spring 463 is fixedly connected to the annular curved plate 464. Under the pressure of the concrete material, the special-shaped blocking plate 42 rotates around the concave shell 41. During the downward rotation of the special-shaped blocking plate 42, it will come into contact with the rotating ball 44 and squeeze the rotating ball 44. Because the sliding frame 43 slides on the inner wall of the curved tube 1, when the rotating ball 44 is squeezed, the rotating ball 44 will drive the sliding frame 43 to move, and the sliding frame 43 will drive the sliding plate 453 to move. The sliding plate 453 slides on the inner wall of the fixed shell 451, pushing the water inside the fixed shell 451 and the annular shell 452, and the water flows into the inside of the drain pipe 461 through the annular shell 452, and the water flows into the inside of the annular water spray box 462 through the drain pipe 461. The water flows downwardly press the annular curved plate 464 in the annular water spray box 462, so that the annular curved plate 464 moves downward inside the annular water spray box 462. When the annular curved plate 464 moves to the bottom of the inner cavity of the annular water spray box 462, one side of the annular curved plate 464 is no longer The annular water spray box 462 is blocked, and water will spray water through the annular water spray box 462 to the connection between the concave shell 41 and the special-shaped blocking plate 42, so that the curved tube 1 can clean the connection between the concave shell 41 and the special-shaped blocking plate 42 when conveying concrete materials. The inner wall of the annular zigzag plate 464 is slidably connected to the inner cavity of the annular water spray box 462. The bottom of the annular zigzag plate 464 away from the tension spring 463 is fixedly connected with an extrusion ring 465. When the annular zigzag plate 464 descends, the annular zigzag plate 464 drives the extrusion ring 465 to descend. During the descent of the extrusion ring 465, one side of the special-shaped blocking plate 42 can be pressed down, further improving the fitting effect between the special-shaped blocking plate 42 and the inner wall of the curved tube 1. When the concrete material is no longer transported, the elastic deformation of the tension spring 463 drives the annular curved plate 464 to move upward at the inner wall of the annular water spray box 462. During the upward movement of the annular curved plate 464, the opening of the annular water spray box 462 can be blocked to prevent the water flow inside the annular shell 452 from entering the interior of the curved tube 1, thereby reducing the consumption of water resources.

[0039] In embodiment 2, an extrusion assembly 47 is provided on the side wall of the sliding plate 453, and the extrusion assembly 47 includes a flexible rotating rod 471 rotatably connected to the side of the sliding plate 453 away from the sliding frame 43. The material of the flexible rotating rod 471 is flexible and can perform slight bending movement to prevent the flexible rotating rod 471 from getting stuck during the movement at the connection between the fixed shell 451 and the annular shell 452. The end of the flexible rotating rod 471 away from the sliding plate 453 is rotatably connected to a sliding ring 472, and the outer wall of the sliding ring 472 is slidably connected to the inner wall of the annular shell 452.

When the tooth plate frame 474 descends, the tooth plate frame 474 drives the vertical rod 475 to descend, and the vertical rod 475 drives the first ring plate 476 to descend. During the descending process of the first ring plate 476, the bottom of the outer wall of the casting pipe 2 can be scraped and cleaned, thereby further improving the working stability of the casting pipe 2.

[0042] A cleaning assembly 48 is provided on the outer wall of the curved cylinder 1, and the cleaning assembly 48 includes a cross bar 481 fixedly connected to one side of the outer wall of the curved cylinder 1 close to the fixed shell 451, and the outer wall of the cross bar 481 is rotatably connected to the first bevel gear 482, and one side of the outer wall of the first bevel gear 482 is meshedly connected to the side wall of the gear plate frame 474.

[0043] The outer wall of the bent cylinder 1 close to the cross bar 481 is fixedly connected with a carrier 483, and a second bevel gear 484 is rotatably connected to one side of the top of the carrier 483, and an outer wall of the second bevel gear 484 is rotatably connected to the side wall of the first bevel gear 482, and a gear ring 485 is rotatably connected to one side of the outer wall of the bottom end of the second bevel gear 484, and the bottom of the gear ring 485 is rotatably connected to the top of the carrier 483, and four connecting blocks 486 are fixedly connected to the inner wall of the gear ring 485 respectively, and a cleaning plate 487 is fixedly connected to the bottom of the connecting block 486, and one side of the cleaning plate 487 contacts one side of the outer wall of the casting pipe 2. When the sliding plate 453 moves, the sliding plate 453 drives the flexible rotating rod 471 to move, and is limited by the annular shell 452, and the flexible rotating rod 471 drives the sliding ring 472 along the annular shell The inner wall of 452 performs a vertical downward movement, the sliding ring 472 drives the connecting frame 473 to descend, the connecting frame 473 drives the toothed plate frame 474 to descend, and the toothed plate frame 474 meshes with the side wall of the first bevel gear 482 during the descent process, so that the first bevel gear 482 rotates around the cross bar 481, the first bevel gear 482 drives the second bevel gear 484 to rotate, the second bevel gear 484 drives the gear ring 485 to rotate, and the gear ring 485 rotates, and the connecting block 486 is driven to rotate during the rotation process, and the connecting block 486 is brought into contact with the outer wall of the casting pipe 2 during the rotation process, so as to scrape off the concrete particles adhered to the outer wall of the casting pipe 2, and prevent the concrete particles from adhering to the outer wall of the casting pipe 2 for a long time, and the concrete material becomes hard, thereby affecting the subsequent scraping work of the casting pipe 2.

[0044] When in use, the mixed concrete material is poured into the interior of the curved cylinder 1, and the concrete material enters the interior of the pouring pipe 2 through the curved cylinder 1, and the concrete material is poured toward the construction site through the pouring pipe 2. When the concrete material enters the interior of the curved cylinder 1, it is blocked by the setting of the special-shaped blocking plate 42, and the circulation speed of the concrete material is reduced to prevent the impact force generated when a large amount of concrete material is transported from being too large, which causes the concrete material to splash when it is distributed, thereby improving the stability of material feeding. Under the pressure of the concrete material, the special-shaped blocking plate 42 rotates around the concave shell 41, and the special-shaped blocking plate 42 will contact the rotating ball 44 during the downward rotation process, squeezing the rotating ball 44. Because the sliding frame 43 slides on the inner wall of the curved cylinder 1, when the rotating ball 44 is squeezed, the rotating ball 44 will drive the sliding frame 43 to move, and the sliding frame 43 drives the sliding plate 453 to move, and the sliding plate 453 The water flows through the annular shell 452 to the inside of the drain pipe 461, and then flows through the drain pipe 461 to the inside of the annular water spray box 462. The water flows downward on the annular curved plate 464 in the annular water spray box 462, causing the annular curved plate 464 to move downward inside the annular water spray box 462. When the annular curved plate 464 moves to the bottom of the inner cavity of the annular water spray box 462, one side of the annular curved plate 464 no longer blocks the annular water spray box 462, and the water flows through the annular water spray box 462 to spray water toward the connection between the concave shell 41 and the special-shaped baffle plate 42, so that the curved cylinder 1 can clean the connection between the concave shell 41 and the special-shaped baffle plate 42 when conveying concrete materials, thereby preventing the connection between the concave shell 41 and the special-shaped baffle plate 42 from being blocked by concrete materials, thereby improving the operating stability of the device.

[0045] When the annular curved plate 464 descends, the annular curved plate 464 drives the extrusion ring 465 to move downward. During the descending process, the extrusion ring 465 can press down one side of the special-shaped blocking plate 42, further improving the fitting effect between the special-shaped blocking plate 42 and the inner wall of the curved tube 1. When the concrete material is no longer transported, the elastic deformation of the tension spring 463 drives the annular curved plate 464 to move upward at the inner wall of the annular water spray box 462. During the upward movement of the annular curved plate 464, the opening of the annular water spray box 462 can be blocked to prevent the water flow inside the annular shell 452 from entering the interior of the curved tube 1, thereby reducing the consumption of water resources.

[0046] When the sliding plate 453 moves, the sliding plate 453 drives the flexible rotating rod 471 to move. The flexible rotating rod 471 is limited by the annular shell 452, and the sliding ring 472 drives the connecting frame 473 to descend. The connecting frame 473 drives the toothed plate frame 474 to descend. During the descent process, the toothed plate frame 474 will mesh with the side wall of the first bevel gear 482, so that the first bevel gear 482 moves around the cross bar 481. The first bevel gear 482 drives the second bevel gear 484 to rotate, and the second bevel gear 484 drives the gear ring 485 to rotate. The gear ring 485 drives the connecting block 486 to rotate during the rotation. The connecting block 486 comes into contact with the outer wall of the casting pipe 2 during the rotation, thereby scraping off the concrete particles adhered to the outer wall of the casting pipe 2, preventing the concrete particles from adhering to the outer wall of the casting pipe 2 for a long time, causing the concrete to harden, thereby affecting the subsequent scraping work of the casting pipe 2.

[0047] When the tooth plate frame 474 descends, the tooth plate frame 474 drives the vertical rod 475 to descend, and the vertical rod 475 drives the first ring plate 476 to descend. During the descending process of the first ring plate 476, the outer wall bottom of the casting pipe 2 can be scraped and cleaned, which further improves the working stability of the casting pipe 2. The first ring plate 476 drives the round rod frame 477 to descend, and the round rod frame 477 drives the second ring plate 478 to descend. During the descending process of the second ring plate 478, it will contact the top of the fixed ring 3, so that the fixed ring 3 is pressed downward, and the fixed ring 3 drives the casting pipe 2 to be pressed downward, prompting the casting pipe 2 to stretch downward, preventing the casting pipe 2 from deforming and twisting during the scraping process of the cleaning plate 487 on the casting pipe 2, thereby improving the scraping effect of the cleaning plate 487 on the casting pipe 2.
