Description
Technical Field
[0001] The utility model belongs to the technical field of concrete feeding, in particular to a feeding device for concrete production. Background Art
[0002] Concrete is an engineering composite material that uses cementitious materials to bind aggregates together. When we talk about concrete, we usually mean cement as a cementitious material, sand and stone as aggregates, and possibly water (as well as possible admixtures and additives), mixed, stirred, molded and cured in a specific proportion to obtain cement concrete, which is also often called ordinary concrete. This material is widely used in civil engineering. Concrete is popular because of its abundant raw materials, low price and relatively simple production process.
[0003] However, in the current concrete production process, there is a problem that cannot be ignored: when concrete is added to the production equipment, it tends to accumulate below the feeding nozzle and on the inner wall of the production equipment. As the feeding process continues, the pile height of the concrete will gradually increase, showing a rock climbing-like upward trend. This not only seriously affects the uniformity of the feeding, but in extreme cases, it may also cause the feeding nozzle to be blocked, causing great inconvenience to the production process.
[0004] Therefore, it is very necessary to invent a kind of concrete production feeding device. Utility Model Content

[0009] Preferably, the spacing between a plurality of the dividing plates evenly and respectively installed on the dividing cone is a retention area; the dividing plates are located above the dividing bottom plates, and the cross-section of the dividing bottom plates is a triangle.
[0010] Preferably, the one-way bearing mounted on the sleeve comprises a plurality of rollers, needle rollers or ball rollers, and the shape of the rolling seat is designed so that it can only roll in one direction, but will generate great resistance in the other direction.

[0021] As attached Figure 1 To Attachment Figure 3 As shown:
[0022] The utility model provides a feeding device for concrete production, comprising a concrete dispersing mechanism 1, a concrete converging mechanism 2, a feeding pipe 3 and a feeding tank 4, wherein the concrete dispersing mechanism 1 and the concrete converging mechanism 2 are installed in concrete production equipment; the concrete dispersing mechanism 1 is connected with the feeding tank 4 through the feeding pipe 3, and the feeding tank 4 is installed on the outside of the concrete production equipment.
[0023] The concrete dispersing mechanism 1 comprises a dispersing cover 11, a feed pipe opening 12, a sleeve 13, a one-way bearing 14, a dispersing cone 15 and a dispersing plate 16. The feed pipe opening 12 installed on the dispersing cover 11 is connected to the feeding pipe 3, and the dispersing cover 11 is fixedly installed in the concrete production equipment; the sleeve 13 is rotatably installed on the dispersing cover 11, and the sleeve 13 is connected to the mixing shaft of the concrete production equipment through the one-way bearing 14. The lower end of the sleeve 13 is rotatably connected to the concrete converging mechanism 2, and the one-way bearing 14 is fixedly connected to the dispersing cone 15. A plurality of dispersing plates 16 are installed on the dispersing cone 15. The concrete dispersing mechanism 1 uses the power of the production equipment and drives the entering concrete to rotate, ensuring that it falls evenly around the inner wall of the production equipment.
[0024] The concrete convergence mechanism 2 comprises a sealing cover 21, a material distribution bottom plate 22, a connection plate 23 and a convergence body 24. The sealing cover 21 is fixedly connected to the material distribution cover 11 and the concrete production equipment; a plurality of material distribution bottom plates 22 and a convergence body 24 are fixedly mounted on the sealing cover 21, and the material distribution bottom plate 22 is fixed to the connection plate 23; the connection plate 23 is rotatably connected to the shaft sleeve 13 through a bearing. The concrete convergence mechanism 2 converges part of the falling concrete to the middle of the production equipment.
[0025] Embodiment 1:
[0026] Specifically, the feed pipe opening 12 is installed on the distribution cover 11 and is located on one side above the distribution cone 15, ensuring that the concrete is first guided by the distribution cover 11 when entering the concrete dispersing mechanism 1. The distribution cone 15 is located inside the distribution cover 11 and is designed as a conical boss structure. This conical boss structure can effectively disperse the concrete entering through the feed pipe opening 12, guide the concrete to flow along the inclined surface of the distribution cone 15, and thus avoid the concrete from being concentrated in a certain area at the initial stage of feeding.
[0027] Specifically, the spacing between the plurality of dividing plates 16 evenly installed on the dividing cone 15 is a retention area; when the concrete flows through the dividing cone 15, it can be temporarily retained between the dividing plates 16, thereby achieving initial dispersion and uniform distribution of the concrete. The dividing plates 16 are located above the dividing bottom plate 22, and the cross-section of the dividing bottom plate 22 is designed to be triangular. This triangular design further enhances the fluidity of the concrete during the feeding process, allowing the concrete to flow more smoothly downward along the surface of the dividing cone 15 and achieve uniform distribution under the guidance of the dividing plates 16.
[0028] Specifically, the one-way bearing 14 installed on the sleeve 13 includes multiple rollers, needle rollers or ball rollers. The shape of the rolling seat hole is designed so that it can only roll in one direction, and will generate great resistance in the other direction. It can rotate freely in one direction, but will be locked in the other direction. While relying on the power of the stirring shaft of the production equipment, it does not affect the normal stirring work of the stirring shaft.
[0029] Furthermore, during the process of adding concrete, the one-way bearing 14 is locked, the agitator shaft drives the sleeve 13, and the dividing cone 15 rotates, so as to achieve the dispersed discharge of concrete. After the addition is completed, the agitator shaft rotates in the opposite direction, the one-way bearing 14 is unlocked, and the agitator shaft will not drive the sleeve 13 to rotate, so that the concrete is mixed in production.
[0030] Specifically, the converging body 24 is a conical geometric body, which shrinks inward and has an inclined surface. This allows the concrete to gradually converge toward the center along the inclined surface when flowing through. At the same time, gaps are reserved between the converging bodies 24 to allow the concrete to pass through. The existence of these gaps not only ensures that the concrete can pass smoothly, but also can redisperse the concrete to a certain extent to prevent it from being over-concentrated. The converging body 24 is located below the material distribution bottom plate 22, and together with the material distribution cone 15 and the material distribution plate 16 and other components, it constitutes a complete concrete feeding system.
[0031] Furthermore, after the concrete enters the distribution cover 11 from the feed pipe port 12, it is first dispersed by the distribution cone 15 and the distribution plate 16, and then part of the concrete enters the area where the convergence body 24 is located under the guidance of the distribution bottom plate 22, and the rest of the concrete falls through the gaps between the convergence bodies 24. The part of the concrete located at the convergence body 24 is gradually gathered to the center of the production equipment under the action of the inclined surface, ensuring that the concrete is evenly distributed inside the entire production equipment.
[0032] Embodiment 2:
[0033] When concrete flows from the feeding tank 4 through the feeding pipe 3 into the distribution cover 11, it first contacts the distribution cone 15. The conical boss structure of the distribution cone 15 ingeniously guides the concrete to its inclined surface, so that it is initially dispersed, effectively avoiding the problem of the concrete being concentrated in a certain area at the initial stage of feeding.
[0034] In order to further enhance the dispersing effect of concrete, a plurality of dispersing plates 16 are evenly distributed on the dispersing cone 15. The spacing between these dispersing plates 16 constitutes a retention area, so that the concrete can be temporarily retained when flowing through these areas, thereby achieving further uniform dispersion of the concrete.
[0035] The shaft sleeve 13 is a key component connecting the concrete dispersing mechanism 1 and the agitator shaft of the production equipment, and is connected to the agitator shaft through a one-way bearing 14. When the agitator shaft rotates, the one-way bearing 14 is locked, and the agitator shaft drives the material distribution cone 15 to rotate through the shaft sleeve 13. This rotation can drive the concrete to fall evenly around the inner wall of the production equipment, ensuring the uniform distribution of the concrete during the feeding process. When the agitator shaft rotates in the opposite direction, the one-way bearing 14 is unlocked, and the shaft sleeve 13 stops rotating, so as not to affect the mixing work of the agitator shaft.
[0036] The concrete convergence mechanism 2 is responsible for converging part of the falling concrete to the middle of the production equipment. The convergence body 24 is designed as a conical geometric body, which shrinks inward and has an inclined surface. When the concrete enters the convergence body 21 area through the material distribution bottom plate 22, part of the concrete is gradually guided to the center of the production equipment under the action of the inclined surface. At the same time, gaps are reserved between the convergence bodies to allow concrete to pass through. These gaps not only ensure the smooth passage of concrete, but also can redisperse the concrete to a certain extent to prevent it from being over-concentrated.
[0037] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
