Description

TECHNICAL FIELD

[0001] The present application relates to a material distribution device, in particular to a concrete mixing and distribution device. BACKGROUND

[0002] Concrete mixing and distribution refers to the whole process of uniformly and continuously pouring mixed concrete to the formwork or construction working surface through a device integrating mixing and distribution functions. Concrete mixing and distribution is essentially a dynamic construction process that ensures the quality of concrete. It emphasizes not only simple "transportation", but also maintaining the workability of concrete through mixing and achieving precise construction pouring through distribution. In modern construction engineering, the pouring and distribution of concrete is a key step that affects the construction quality, efficiency and safety. Currently, on-site concrete distribution is mainly based on the cooperation of concrete pump trucks and fixed distribution rods.

[0003] This way is prone to segregation during transportation or standing, and the uniformity of the concrete will further deteriorate during feeding to the distribution system, resulting in uneven quality of the poured body and affecting the structural strength.

[0041] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0042] This application provides a concrete mixing and spreading device.

[0043] Example 1, as Figures 1-6 As shown.

[0044] A concrete mixing and placing device includes a base plate 1. This device can be used independently in a designated location or placed on a transport truck. If placed on a transport truck, the base plate 1 is simply fixed to the truck.

[0045] A concrete mixing and placing device further includes an external swing support device 2, installed at the top corner of the base plate 1. This stabilizes the entire device and increases its stability during the placing process.

[0046] The external swing support device 2 includes a rotating support column 21, an external swing rod 22, a hydraulic support rod 23, and a support base 24. Rotating support columns 21 are installed at each corner of the top surface of the base plate 1. An external swing rod 22 is installed at the upper rotating end of each rotating support column 21, and a hydraulic support rod 23 is installed at the other end of the external swing rod 22. The support base 24 is installed at the bottom end of the hydraulic support rod 23. The rotating support column 21 consists of an upper column and a lower column. The upper column is rotatably connected to the top surface of the lower column. A power source inside the rotating support column 21 drives the upper column to rotate, thereby causing the hydraulic support rod 23 to extend outward via the external swing rod 22, supporting the equipment. In use, the hydraulic support rod 23 extends, causing the support base 24 to press against the ground. The external swing rod 22 can significantly increase the span between support points, making the support more stable.

[0047] The support base 24 includes an upper base 241, a rotating ball 242, and a support plate 243. The upper base 241 is mounted on the bottom surface of the hydraulic support rod 23. The bottom of the upper base 241 has an inner groove adapted to the rotating ball 242. The middle of the bottom surface of the support plate 243 is fixedly connected to the rotating ball 242, and the rotating ball 242 is connected to the inner groove via a ball hinge. The support base 24 achieves self-adaptive support, allowing the equipment to adapt to various uneven and inclined ground surfaces during support. In use, the hydraulic support rod 23 extends, pressing the support base 24 against the ground. At this time, the support plate 243 contacts the ground. When the ground is inclined, the rotating ball 242 rotates within the inner groove of the upper base 241, thereby achieving leveling.

[0048] A concrete mixing and placing device further includes a vertical mixing unit 3, which is installed on the top of the base plate 1 to mix the concrete and avoid "segregation" and "initial setting" during the placing process, which would lead to uneven quality of the poured body and affect the structural strength.

[0049] The vertical mixing device 3 includes a mixing tank 31, a feeding pipe 32, a mixing motor 33, a central shaft 34, a dispersing disc 35, a mixing assembly 36, a bottom collecting hopper 37, and a mixing partition plate 38.

[0050] A mixing tank 31 is vertically installed on one side of the top surface of the base plate 1. The mixing tank 31 is a hollow cylindrical box structure. A feed pipe 32 is installed through the top wall of the mixing tank 31. A mixing partition plate 38 is installed at the bottom of the mixing tank 31, dividing its internal cavity into an upper mixing chamber and a lower electrical chamber. A mixing motor 33 is installed on the top surface of the electrical chamber. The output shaft of the mixing motor 33 extends into the mixing chamber and is fixedly connected to the bottom surface of the central shaft 34. The bottom end of the central shaft 34 is rotatably connected to the center of the bottom surface of the mixing chamber. The mixing motor 33 drives the central shaft 34 to rotate. A dispersion disc 35 is provided at the top of the central shaft 34. The dispersion disc 35 is located directly below the feed pipe 32. The dispersion disc 35 has an umbrella-shaped structure and evenly disperses the concrete introduced by the feed pipe 32, facilitating subsequent mixing. Several mixing components 36 are provided in the middle of the central shaft 34, and a bottom collection hopper 37 is provided at the bottom of the mixing chamber. After being mixed by the mixing assembly 36, the concrete is collected in the bottom hopper 37 at the bottom.

[0051] The stirring assembly 36 includes a guide ring 361 and a multi-stage stirring shaft 362. The stirring chamber is provided with a plurality of guide rings 361 at equal intervals from top to bottom. The guide rings 361 have an inwardly concave structure, with the inner diameter decreasing from bottom to bottom. The multi-stage stirring shafts 362 are provided on the outer side of the central shaft 34 at the same height as each guide ring 361. The multi-stage stirring shafts 362 cooperate with the guide rings 361.

[0052] The multi-stage stirring shaft 362 includes an upper stirring shaft, a middle stirring shaft, and a lower stirring shaft, arranged sequentially from top to bottom outside the central shaft 34. The length of the middle stirring shaft is shorter than that of the upper stirring shaft, and the length of the lower stirring shaft is shorter than that of the middle stirring shaft. The reduction in length is adapted to the reduction in the inner diameter of the guide ring 361. The upper stirring shaft, the middle stirring shaft, and the lower stirring shaft are arranged alternately.

[0053] Concrete falls from the top feed pipe 32 into the rotating dispersion disc 35, where it is centrifugally dispersed into a uniform curtain of material. Subsequently, the concrete undergoes the following process: falling to the first guide ring 361—being guided to the center—being cut and thrown outwards by the first multi-stage mixing shaft 362—falling to the second guide ring 361—being guided to the center—being cut and thrown outwards by the second multi-stage mixing shaft 362. This "rotary cutting-collision" process is repeated three times until the material falls into the bottom collection hopper 37, completing efficient and forced convection mixing.

[0054] This technical solution has a high mixing intensity, and the zigzag falling path creates excellent mixing conditions.

[0055] Meanwhile, the multi-stage mixing shaft 362 includes a three-layer mixing structure, which is equivalent to three mixing collisions occurring within a single layer of concrete, greatly improving the mixing effect.

[0056] A connecting ring 39 is provided between adjacent guide rings 361. The connecting ring 39 fills the gap below the guide ring 361 to prevent concrete from sticking there.

[0057] A mixing and cooling device 4 is installed on the outside of the mixing tank 31. The circulating coolant removes the frictional heat generated during mixing, effectively delaying the initial setting of the concrete.

[0058] The stirring and cooling device 4 includes a storage tank 41 and a circulation pump 42. The guide ring 361 has a hollow structure. The storage tank 41 stores coolant inside, and the circulation pump 42 is installed outside the storage tank 41. The circulation pump 42 is connected to the storage tank 41 and the inner cavity of the guide ring 361 through pipes. The guide ring 361 is also connected to the storage tank 41 through a pipe. The circulation pump 42 pumps the coolant inside the storage tank 41 into the guide ring 361. Excess coolant in the guide ring 361 flows back to the storage tank 41 through the pipes, realizing the circulation of coolant and dissipating the friction heat generated by stirring.

[0059] A concrete mixing and distributing device further includes a screw discharge device 5, which is installed at the bottom of the vertical mixing device 3 to discharge the mixed concrete.

[0060] The spiral discharge device 5 includes a discharge motor 51, a discharge shaft 52, and a discharge pipe 53. The bottom hopper 37 is a hollow structure, and two discharge motors 51 are installed inside the bottom hopper 37. The output shafts of the discharge motors 51 extend to the outside of the bottom hopper 37 and are fixedly connected to one end of the discharge shaft 52. The discharge shaft 52 is an auger structure, and the two discharge shafts 52 are located on both sides of the central shaft 34. A discharge pipe 53 is provided through one side of the mixing chamber, and the two discharge shafts 52 face the discharge pipe 53. The mixed concrete is conveyed to the discharge pipe 53 by the discharge motors 51, which drive the discharge shafts 52, for subsequent concrete distribution.

[0061] A concrete mixing and spreading device further includes a multi-angle spreading device 6; installed on the top surface of the base plate 1, it spreads the discharged concrete.

[0062] The multi-angle concrete placement device 6 includes a vertical lifting device 61 and a rotation control device 62. The vertical lifting device 61 is installed on one side of the top surface of the base plate 1, and the rotation control device 62 is installed on the top of the vertical lifting device 61. Concrete is discharged from the discharge pipe 53 into the vertical lifting device 61, and then the rotation control device 62 precisely pours the concrete to the designated position, while also preventing the placement pipe 629 from shaking, making the pouring positioning more accurate.

[0063] The vertical lifting device 61 includes a lifting support 611, a lifting box 612, a lifting motor 613, a lifting partition plate 614, and a lifting auger 615. The lifting support 611 and the lifting box 612 are vertically mounted on the top surface of the base plate 1. The lifting box 612 is located inside the lifting support 611, and its inner cavity is connected to the discharge pipe 53. A partition plate is provided at the bottom of the inner cavity of the lifting box 612, and the lifting motor 613 is mounted on the bottom surface of the partition plate. The output shaft of the lifting motor 613 extends to the upper part of the partition plate and is fixedly connected to the bottom end of the lifting auger 615. The bottom end of the lifting auger 615 is rotatably connected to the lifting partition plate 614. Concrete discharged from the discharge pipe 53 enters the lifting box 612, and then the lifting motor 613 drives the lifting auger 615 to lift the concrete to a certain height, facilitating subsequent targeted pouring.

[0064] The slewing control device 62 includes a slewing chassis 621, a slewing motor 622, a slewing gear 623, a slewing outer frame 624, a slewing inner frame 625, a track 626, a moving push rod 627, a moving base plate 628, and a material distribution tube 629. The top of the lifting bracket 611 is slidably connected to the bottom surface of the slewing chassis 621. The inner side of the slewing chassis 621 is provided with meshing teeth. The slewing motor 622 is mounted on the upper part of the lifting bracket 611. A slewing gear 623 is mounted on the output shaft of the slewing motor 622. The slewing gear 623 meshes with the meshing teeth on the inner side of the slewing chassis 621. The top of the slewing chassis 621... A rotating outer frame 624 is provided, and a track 626 is installed inside the rotating outer frame 624. A rotating inner frame 625 is slidably connected to the top surface of the track 626. A movable base plate 628 is provided on one side of the rotating inner frame 625. A movable push rod 627 is installed on the side of the movable base plate 628 facing the rotating outer frame 624. The output end of the movable push rod 627 is fixedly connected to one end of the rotating outer frame 624. One end of the concrete placing pipe 629 is connected to the top of the lifting box 612, and the other end of the concrete placing pipe 629 passes through the rotating outer frame 624 and the rotating inner frame 625, and exits from the bottom of the other end of the rotating inner frame 625. In use, the rotating motor 622 meshes with the inner side of the rotating chassis 621 through the rotating gear 623, driving the rotating chassis 621 to rotate. This, in turn, drives the rotating outer frame 624 to rotate, realizing the adjustment of the concrete pouring angle. The rotary motor 622 can rotate in both directions, which facilitates 360-degree directional adjustment of the fabric tube 629.

[0065] Then, the movable push rod 627 extends and retracts, thereby driving the rotating inner frame 625 to extend and retract on the track 626, thereby adjusting the distance for concrete pouring.

[0066] The slewing control device 62 further includes a slewing support plate 631, sliding rods 632, an end motor 633, an end gear 634, a rotating gear ring 635, a six-legged parallel platform 636, a pitch adjustment support plate 637, a pitch adjustment push rod 638, and a fabric control ring 639. The slewing support plate 631 is installed at the bottom of the outer end of the inner slewing frame 625. Several sliding rods 632 are slidably connected to the inner side of the slewing support plate 631. A six-legged parallel platform is provided at the bottom end of the sliding rods 632. 636, an end motor 633 is mounted on the bottom surface of the rotary support plate 631, and an end gear 634 is mounted on the output shaft of the end motor 633. The end gear 634 meshes with the rotating gear ring 635 for transmission. A pitch adjustment support plate 637 is provided on one side of the bottom surface of the six-legged parallel platform 636, and a pitch adjustment push rod 638 is rotatably connected to the other side. The other ends of the pitch adjustment support plate 637 and the pitch adjustment push rod 638 are rotatably connected to the top surface of the fabric control ring 639.

[0067] In use, the end motor 633 starts, and drives the rotating gear ring 635 to rotate through the end gear 634, which in turn drives the six-legged parallel platform 636 below to rotate through the sliding rod 632 fixedly connected to it.

[0068] The six-legged parallel platform 636 includes an upper ring plate 6361, a lower ring plate 6362, a telescopic push rod 6363, and a ball joint base 6364. Several sets of ball joint bases 6364 are provided on the top surface of the lower ring plate 6362, one above the other, in a one-to-one correspondence. A telescopic push rod 6363 is installed between two corresponding ball joint bases 6364. Both the upper and lower ends of the telescopic push rod 6363 are ball joint connected to the ball joint base 6364.

[0069] The six-legged parallel platform 636 can arbitrarily change the orientation of its bottom end by extending and retracting different telescopic push rods 6363. Simultaneously, the six-legged parallel platform 636 is equipped with several distance sensors, vibration sensors, displacement sensors, etc., which can detect the swaying of the six-legged parallel platform 636 and the fabric passing through it in real time, and then actively extend and retract to counteract the swaying of the fabric tube 629.

[0070] The fabric control ring 639 is controlled by the pitch adjustment push rod 638. When the pitch adjustment push rod 638 extends or retracts, it drives the fabric control ring 639 to adjust the pitch angle around the rotational connection with the pitch adjustment support plate 637. This achieves the final angle adjustment of the end of the fabric tube 629.

[0071] The inner rotating frame 625, the six-legged parallel platform 636, and the fabric control ring 639 are all equipped with clamps on their inner sides. The fabric tube 629 passes through several clamps and extends from the bottom end of the fabric control ring 639.

[0072] The rotary support plate 631, the six-legged parallel platform 636, and the concrete placement control ring 639, with their three-level adjustments at the end of the concrete placement tube 629, enable concrete pouring at any angle and within any range, greatly improving the flexibility of concrete pouring. This allows the concrete placement tube 629 to enter the designated pouring position from any desired angle. These three structures constitute a complete spherical coordinate precision robot. This improves the positioning accuracy of the end of the concrete placement tube 629 from the traditional ±30 cm to within ±10 cm, or even at the millimeter level, and achieves "instant stop and stability," increasing concrete placement efficiency by more than 30%.

[0073] The push rod structures used in the above technical solutions are all electric push rods, which can be selected by those skilled in the art based on the moving length and installation conditions.

[0074] When using this invention:

[0075] Phase 1: Equipment Deployment and Self-Preparation.

[0076] Move the equipment to the designated location on the construction site, and then activate the external swing support device. The rotating support column drives the hydraulic support rod through the external swing rod to press the support base against the ground for support.

[0077] Phase 2: Concrete receiving and homogenization.

[0078] Concrete raw materials (or ready-mixed concrete) are fed into the equipment through the top discharge pipe. After being initially dispersed by the dispersion disc, the concrete material enters the vertical tower-type convection mixing system. Forced and efficient mixing is achieved in the zigzag convection path formed by the guide ring and the multi-stage mixing shaft, thoroughly preventing segregation and ensuring the homogeneity of the concrete.

[0079] Phase 3: Intelligent and precise material placement and pouring.

[0080] The mixed concrete falls into the bottom hopper, and the distribution pipe outlet is moved to a designated position by a rotary control device. Finally, the concrete is fed into the vertical lifting device through the screw conveyor, which lifts the concrete and then pours it at the designated position through the distribution pipe.
