Technical Field
[0001] This utility model relates to the field of commercial concrete production, specifically to a commercial concrete mixing device. Background Technology
[0002] Concrete, also known as concrete, is a general term for engineering composite materials in which aggregates are bound together by cementing materials. Generally, concrete refers to concrete made by mixing cement as cementing material, sand and stone as aggregates, and water or other liquids in a certain proportion.
[0003] During concrete mixing, concrete adheres to the inner wall of the mixing device and the mixing blades. If not cleaned in time, the concrete hardens and becomes extremely difficult to clean after solidification. Furthermore, most existing mixing devices stir in one direction, which prevents the raw materials inside the concrete from being distributed quickly and evenly. In summary, existing concrete mixing devices suffer from the following drawbacks: concrete easily adheres to the inner wall of the mixing device and the mixing blades, requiring timely manual cleaning, which is labor-intensive, and the mixing speed is relatively slow, resulting in low practicality. Utility Model Content
[0004] To address the problems of existing concrete mixing devices where concrete easily adheres to the inner wall and mixing blades, requiring timely manual cleaning, which is labor-intensive, and the mixing speed is slow, resulting in low practicality, this utility model provides a commercial concrete mixing device.
[0005] According to an embodiment of this utility model, a commercial concrete mixing device includes a cylindrical body. The bottom of the body is funnel-shaped and has a sealable discharge port at the bottom. A top plate is suspended and fixedly installed above the top of the body. A first motor is installed on one side above the top plate. A mixing assembly and a water spraying assembly are rotatably installed below the top plate and coaxially arranged with the body. The mixing assembly includes a radial support rotatably connected to the bottom of the top plate. A mixing rod is fixedly connected vertically to the bottom of the body on the lower surface of the far end of the support. The mixing rod is provided with a plurality of... The stirring blades are fixedly connected to the center of the support frame, which includes a hollow water spray pipe. One end of the water spray pipe passes vertically through the top plate and the support frame and extends to the bottom area of the cylinder, with the end closed. A driven gear is fixedly mounted on the water spray pipe located between the bottom of the top plate and the top of the support frame. The output end of the first motor passes vertically through the top plate and is connected to the driven gear. The pipe body is rotatably connected to the top plate and fixedly connected to the support frame. Several water spray holes are distributed on the pipe wall located below the bottom of the support frame.
[0006] A toothed ring is also rotatably installed around the top area of the outer wall of the cylinder, and a second motor-driven toothed ring is also provided on the outer wall of the cylinder. The toothed ring protrudes from the top of the cylinder. Several scrapers are also rotatably installed on the inner wall of the cylinder. One end of the scraper protrudes from the top of the cylinder and is fixedly connected to the inner wall of the toothed ring, and the other end extends towards the bottom of the cylinder. One side of the scraper is set against the inner wall of the cylinder.
[0007] The technical principle of this utility model is as follows: a cylindrical body is used as the container for stirring. The bottom is funnel-shaped to facilitate the collection and discharge of materials. A space for feeding raw materials is reserved in the top plate, which is suspended above the top of the body. A first motor is installed on the top plate as the power source. A stirring assembly and a water spraying assembly are rotatably connected below the top plate. The stirring assembly consists of a radial support, a stirring rod vertically connected to the support, and stirring blades on the stirring rod. The water spraying assembly has a water spray pipe that passes through the center of the support and extends to the bottom of the body, with its end closed. A driven gear is installed on the water spray pipe located between the top plate and the support. The first... The motor's output end passes vertically through the top plate and is connected to the driven gear. The water spray pipe is rotatably connected to the top plate and fixedly connected to the bracket. When the first motor drives the driven gear, the water spray pipe starts to rotate, simultaneously driving the stirring assembly to rotate and perform a stirring action. Several water spray holes on the water spray pipe can also spray water to participate in the mixing of raw materials. After the material is stirred and flows out of the cylinder through the discharge port, the water spray holes can continue to spray water to wash the stirring blades, stirring rods, and inner wall of the stirring assembly. At the same time, the stirring assembly and the water spray pipe can also rotate. Under centrifugal action, combined with water flow, the stirring assembly can be better washed.
[0008] Several scrapers are rotatably installed on the inner wall of the cylinder. At the same time, a second motor installed on the outer wall of the cylinder drives a gear ring mounted at the top of the outer wall to rotate. The gear ring drives several scrapers fixedly connected to the gear ring. One side of the scraper is set against the inner wall of the cylinder. When the scraper rotates, it can remove residual material from the inner wall. At the same time, it can also rotate in the opposite direction to the stirring component during the stirring operation, disrupting the stirring pattern of the material and making the material mixing speed faster. In addition, when the water spray pipe cleans the inner wall of the cylinder, it can also rinse the scrapers, achieving the effect of cleaning the entire stirring device. Attached Figure Description

[0013] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1 and Figure 2 as well as Figure 3 As shown, a commercial concrete mixing device includes a cylindrical body 1. The bottom of the body 1 is funnel-shaped and has a sealable discharge port 11 at the bottom. A top plate 12 is suspended and fixedly installed above the top of the body 1. A first motor 14 is installed on one side above the top plate 12. A mixing assembly and a water spraying assembly are rotatably installed below the top plate 12 and coaxially arranged with the body 1. The mixing assembly includes a radial support 15 rotatably connected to the bottom of the top plate 12. A mixing rod 16 is fixedly connected vertically to the bottom of the body 1 on the lower surface of the distal end of the support 15. The device is provided with several stirring blades 17. The center of the support 15 is fixedly connected to the water spray assembly. The water spray assembly includes a hollow water spray pipe 18. One end of the water spray pipe 18 passes vertically through the top plate 12 and the support 15 and extends to the bottom area of the cylinder 1 and is closed at the end. A driven gear 19 is fixedly provided on the water spray pipe 18 located between the bottom of the top plate 12 and the top of the support 15. Since the water spray pipe 18 at this position also undertakes the function of support and connection, the pipe body of the water spray pipe 18 at this position should be thickened so that the inner wall can withstand the transmission pressure.
[0015] The output end of the first motor 14 vertically passes through the top plate 12 and is equipped with a driving gear that meshes with a driven gear 19. The body of the water spray pipe 18 is rotatably connected to the top plate 12 and fixedly connected to the bracket 15. Several water spray holes 21 are distributed on the wall of the water spray pipe 18 located below the bottom of the bracket 15. The water spray holes 21 are as follows: Figure 1 As shown, the water spray pipes 18 are distributed around the bottom of the support 15, so the entire cylinder 1 is sprayed during spraying. When the water spray pipes 18 rotate, the water flow will form a curved and divergent shape, like a vortex spraying outwards in the opposite direction, so that the stirring blades facing the inner wall of the cylinder 1 will also be sprayed.
[0016] The cylindrical body 1 serves as the container for mixing. The bottom is funnel-shaped to facilitate the collection and discharge of concrete materials. A space for adding concrete materials is reserved in the top plate 12, which is suspended above the top of the body 1. A first motor 14 is installed on the top plate 12 as a power source. A mixing assembly and a water spraying assembly are rotatably connected below the top plate 12. The mixing assembly consists of a radial support 15, a mixing rod 16 vertically connected to the support 15, and mixing blades 17 on the mixing rod 16. The bottom of the mixing rod 16 can also be inclined and extended according to the funnel-shaped structure at the bottom of the body 1. At the same time, the mixing blades 17 are also provided on the inclined mixing rod 16, which can also agitate the concrete materials at the bottom of the body 1, making the materials more thoroughly agitated.
[0017] The radial support 15 can be either a cross-shaped support 15 or a herringbone-shaped support 15, such as... Figure 2 The design is cross-shaped. The water spray pipe 18 in the water spray assembly passes through the center of the bracket 15 and extends to the bottom of the cylinder 1, with its end closed. A driven gear 19 is installed on the water spray pipe 18 located between the top plate 12 and the bracket 15. The output end of the first motor 14 vertically passes through the top plate 12 and is geared to the driven gear 19. Figure 1 and Figure 3 As shown, the water spray pipe 18 is rotatably connected to the top plate 12 and fixedly connected to the bracket 15. When the first motor 14 drives the driven gear 19, the water spray pipe 18 starts to rotate, simultaneously driving the stirring assembly to rotate and perform a stirring function. The several water spray holes 21 on the water spray pipe 18 can also spray water to participate in the mixing of raw materials. Figure 1 and Figure 2 As shown, a sand-proof mesh 22 is provided along the inner wall of the water spray pipe 18 located below the bottom of the support 15 to prevent raw materials from entering the water spray pipe 18. Although the water spray pipe 18 and the stirring assembly are coaxially arranged and the water spray pipe 18 body does not participate in the stirring of raw materials, the stirred raw materials will still rush into the water spray hole 21, so the sand-proof mesh 22 is needed. At the same time, since the water inlet pipe can be connected to a high-pressure water pump as needed, even if sand and gravel are embedded in the water spray hole 21, high-pressure water flow can still impact it.
[0018] After the material is mixed and flows out of the cylinder 1 from the discharge port 11, the water spray hole 21 can continue to spray water to wash the mixing blades 17 and mixing rods 16 of the mixing component and the inner wall. At the same time, the mixing component and the water spray pipe 18 can also rotate. When the mixing component rotates, under the centrifugal force, most of the concrete attached to the mixing component will automatically fall off, and the remaining concrete will slide off the mixing component under the spray of water in a spiral diverging pattern.
[0019] Such as 1 and Figure 2As shown, a gear ring 24 is rotatably installed around the top area of the outer wall of the cylinder 1. It can be installed between the inner wall of the gear ring 24 and the outer wall of the cylinder 1 in a structure similar to a bearing, so that the gear ring 24 can rotate freely. A second motor 23 and a gear on the second motor 23 are also provided on the outer wall of the cylinder 1 to gear-connect the gear ring 24 and drive the gear ring 24 to rotate. The gear ring 24 protrudes from the top of the cylinder 1. Several scrapers 26 are rotatably installed on the inner wall of the cylinder 1. One end of the scraper 26 protrudes from the top of the cylinder 1 and is fixedly connected to the inner wall of the protruding part of the gear ring 24. The other end extends towards the bottom of the cylinder 1. One side of the scraper 26 is set against the inner wall of the cylinder 1.
[0020] Several scrapers 26 are rotatably installed on the inner wall of the cylinder 1, the scrapers 26 as follows: Figure 1 As shown and Figure 3 As shown, the scraper 26 is generally rectangular, but narrows at the top and bottom. A second motor 23 mounted on the outer wall of the cylinder 1 drives a gear ring 24 mounted at the top of the outer wall of the cylinder 1 to rotate. Simultaneously, the gear ring 24 drives several scrapers 26 fixedly connected to it. One side of each scraper 26 is recessed into the inner wall of the cylinder 1. When the scraper 26 rotates, it can remove residual material from the inner wall. Furthermore, because the top of the scraper 26 protrudes from the top of the cylinder 1, it can also scrape away material that may be adhering to the top of the inner wall of the cylinder 1. To prevent material from falling into the space between the gear ring 24 and the cylinder 1... To mitigate the impact of bearing structure on rotation, a protective ring can be installed between the gear ring 24 and the cylinder 1. Since the tooth spacing on the corresponding gears at the output end of the gear ring and the second motor 23 driving the gear ring is relatively large, even if concrete material spills onto the gear teeth, it will not significantly affect the rotation of the gear ring, thus acting as a barrier to the material. Simultaneously, during mixing, it can rotate in the opposite direction to the mixing components, disrupting the material's agitation pattern and accelerating the mixing speed. Furthermore, when the water spray pipe 18 cleans the inner wall of the cylinder 1, it can also flush the scraper 26, achieving the effect of cleaning the entire mixing device.
[0021] Furthermore, the top plate 12 is fan-shaped, covering an area as follows: Figure 3 The area shown is less than half the top area of the cylinder 1, and the remaining open area can be used for feeding. An arc-shaped vertical plate 13 is also fixedly provided on the outer wall of the cylinder 1 in the area below the toothed ring 24. The vertical plate 13 is set according to the outer wall of the cylinder 1, and the bottom of the vertical plate 13 is bent and fixedly connected to the outer wall of the cylinder 1. The vertical plate 13 extends to the top of the cylinder 1 and is horizontally and vertically fixedly connected to the arc-shaped side of the top plate 12.
[0022] Furthermore, such as Figure 1 and Figure 3As shown, the water spray assembly also includes an adapter 20 and a water inlet pipe. The adapter 20 includes a fixing part fixed on the top plate 12 and a rotating part fixedly connected to one end of the water spray pipe 18. The water inlet pipe passes through the top plate 12 and is fixedly connected to the fixing part. The adapter 20 allows the water spray pipe 18 to rotate freely without affecting the water inlet.
[0023] Furthermore, such as Figure 1 and Figure 2 As shown, a support bearing is also fixedly installed on the water spray pipe 18 between the bracket 15 and the driven gear 19. A support rod 27 is also provided on the outer wall of the support bearing. The support rod 27 extends to the inner side of the vertical plate 13 and is fixedly connected thereto. Because the entire stirring assembly and water spray assembly have a large self-weight, the support rod 27 is provided for support. Figure 1 and Figure 2 Although only two rods are shown, it does not mean that only two support rods 27 can be used for support. Furthermore, one end of the support rod 27 does not necessarily have to be fixed to the inside of the vertical plate 13, but can also be fixed to the inner wall of the cylinder 1 on the other side.
[0024] Furthermore, such as Figure 1 As shown, the stirring blade 17 is trapezoidal in shape, and its bottom is vertically inclined on the stirring rod 16. Since concrete is different from ordinary mixing materials, the stirring blade 17 is set as a trapezoid, and the longer bottom end is fixedly connected to the stirring rod 16. This setting increases the strength of the stirring blade 17, and the inclined setting can also relieve force during mixing.
[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the scraper 26 is further provided with an upper support ring 28 and a lower support ring 29 at its top and bottom, respectively. A connecting post 25 is also vertically provided on the outer side of the upper support ring 28. The connecting post 25 extends to the inner wall of the toothed ring 24 and fixes the toothed ring 24 to it. The toothed ring 24 and the scraper 26 are vertically connected by the connecting post 25. The scraper 26 is as follows... Figure 1 and Figure 2 As shown, up to 6 scrapers can be set. The scrapers 26 can be parallel to each other, either vertically or at an angle (the attached diagram in the instruction manual does not show the scrapers set at an angle).
[0026] Furthermore, such as Figure 1 As shown, the discharge port 11 is also provided with a sliding door 30 for closing and opening the discharge port 11. The sliding door 30 closes or opens the discharge port 11. Protruding slide bars 31 are provided on both sides of the sliding door 30. Two corresponding opposite slide grooves can be provided inside the area of the discharge port 11. A locking block is provided at the end of the same side of the two slide grooves, so that the sliding door 30 can be slid without sliding too far out of the slide groove. When discharging, the material can be quickly discharged by simply pulling the sliding door 30.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
