Description

Technical Field

[0001] This utility model belongs to the technical field of steel fiber reinforced concrete, specifically relating to a dispersing and distributing device for end-hook type steel fiber reinforced concrete. Background Technology

[0002] Steel fiber reinforced concrete is a novel multiphase composite material formed by incorporating randomly distributed short steel fibers into ordinary concrete. These randomly distributed steel fibers can effectively inhibit the propagation of microcracks and the formation of macrocracks inside the concrete, significantly improving the tensile, flexural, impact and fatigue properties of concrete, and exhibiting good ductility.

[0003] In the process of mixing and dispersing hooked steel fibers with concrete, a dedicated dispersing and distributing device is usually required. However, existing devices of this type generally suffer from poor uniformity of distribution in practical applications. Since hooked steel fibers are mostly fed manually, fiber clumping and uneven distribution are prone to occur, which seriously affects the final performance of concrete. Therefore, developing a dedicated dispersing and distributing device for hooked steel fiber concrete that can effectively improve fiber dispersion and mixing uniformity not only has significant engineering application value but also meets the urgent needs of the current market.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This embodiment of the present invention provides a dispersing and placing device for end-hook type steel fiber reinforced concrete, comprising: The mixing mechanism 100 includes a mixing box 110. Support legs 120 are fixed at the four corners of the bottom of the mixing box 110. A discharge pipe 130 is connected to the center of the bottom of the mixing box 110. A discharge valve 140 is connected to the inner cavity of the discharge pipe 130. Support plates 150 are fixed to the front and back of the mixing box 110. A material box 160 is fixed to the top of the support plate 150. The front-to-back moving mixing mechanism 200 includes a housing 210, the inner side of which is fixed to the bottom of the outer side of the material box 160. A reciprocating drive assembly 220 is provided in the inner cavity of the housing 210, and a reciprocating moving stirring mechanism 230 is provided on the outer side of the reciprocating drive assembly 220. The vibration dispersion mechanism 300 includes a top rod protrusion 310, the bottom of which is fixed to the top of the reciprocating stirring mechanism 230, and a vibration dispersion cloth assembly 320 is provided at the bottom of the inner cavity of the material box 160.

[0019] The reciprocating drive assembly 220 includes a first motor 221, a drive wheel 222 fixed at the output end of the first motor 221, a driven wheel 224 connected to the surface of the drive wheel 222 via a transmission belt 223, a rotating shaft 225 fixed to the inner side of the driven wheel 224, a bearing seat 226 sleeved on the inner end of the rotating shaft 225, and a sliding rod 227 fixed to the outer side of the transmission belt 223.

[0020] Specifically, the inner side of the first motor 221 is fixed to the inner wall of the housing 210, and the inner side of the bearing seat 226 is fixed to the inner wall of the housing 210. By setting the reciprocating drive assembly 220, it can conveniently drive the reciprocating stirring mechanism 230 to move back and forth, and can evenly mix the materials in the inner cavity of the mixing box 110.

[0021] Furthermore, the reciprocating stirring mechanism 230 includes a moving plate 231. The inner cavity of the moving plate 231 is provided with a sliding groove 232 that is slidably connected to the surface of the sliding rod 227. The front end and rear end of the outer side of the moving plate 231 are both fixed with connecting plates 233, and the outer end of the connecting plate 233 is fixed with a fixing plate 234.

[0022] Preferably, a reciprocating movable plate 235 is fixed to the bottom end of the fixed plate 234, the bottom of the top rod protrusion 310 is fixed to the top of the reciprocating movable plate 235, and a second motor 236 is fixed to both sides of the top of the reciprocating movable plate 235. A stirring rod 237 is fixed to the output end of the second motor 236. The bottom end of the stirring rod 237 extends into the inner cavity of the mixing box 110, and a stirring blade 238 is fixed to the surface of the stirring rod 237. By setting the reciprocating moving stirring mechanism 230, it can move back and forth to uniformly mix the material in the inner cavity of the mixing box 110, so that the end hook steel fiber can be evenly distributed in the concrete.

[0023] It should be noted that the vibration dispersion fabric assembly 320 includes a guide sleeve 321, a guide rod 322 is slidably connected to the inner cavity of the guide sleeve 321, a dispersion plate 323 is fixed to the top of the guide rod 322, a powerful reset spring 324 is sleeved on the surface of the guide rod 322, and the inner cavity of the dispersion plate 323 is provided with uniformly distributed material distribution holes 325.

[0024] The outer side of the guide sleeve 321 is fixed to the bottom of the inner side of the material box 160. The two ends of the high-strength return spring 324 are fixed to the top of the guide sleeve 321 and the bottom of the dispersion plate 323, respectively. By setting the top rod protrusion 310 and the vibration dispersion and distribution assembly 320, the end hook type steel fiber can be vibrated, so that it can fall into the inner cavity of the mixing box 110 evenly and continuously through the material distribution hole 325, thus realizing the uniform addition of end hook type steel fiber in concrete.

[0025] In operation, the second motor 236 in the back-and-forth moving mixing mechanism 200 starts, driving the stirring rod 237 and stirring blade 238 to rotate and uniformly mix the materials in the mixing box 110. Simultaneously, the first motor 221 starts, driving the drive wheel 222 to rotate, which in turn drives the driven wheel 224 to rotate via the transmission belt 223. The driven wheel 224 rotates, causing the rotating shaft 225 to rotate within the bearing seat 226. The transmission belt 223 rotates, causing the sliding rod 227 to move at the rear end of the sliding groove 232, and simultaneously pulling the moving plate 231 to move. The movement of the moving plate 231 drives the connecting plate 233 and the fixed plate 234 to move, and the movement of the fixed plate 234 drives the reciprocating moving plate 235 and the second motor 236 to move. 6. The stirring rod 237 and stirring blade 238 move back and forth to stir and mix the material in the inner cavity of the mixing box 110. At the same time, the reciprocating movable plate 235 moves back and forth, driving the top rod protrusion 310 to move. The movement of the top rod protrusion 310 pushes the guide rod 322 upward. The upward movement of the guide rod 322 drives the dispersing plate 323 to move upward. When the top rod protrusion 310 exceeds the guide rod 322, the elasticity of the strong reset spring 324 causes the dispersing plate 323 to vibrate, thereby causing the hook-shaped steel fiber to fall evenly and continuously into the inner cavity of the mixing box 110 through the material distribution hole 325. This achieves the uniform addition of the hook-shaped steel fiber in the concrete, effectively promotes the uniform dispersion of the hook-shaped steel fiber in the concrete, and avoids fiber clumping.

[0026] In summary, the forward and backward moving mixing mechanism 200 enables thorough and uniform mixing of the hook-shaped steel fiber concrete within the mixing chamber 110. This structure effectively promotes the uniform dispersion of the hook-shaped steel fibers in the concrete, prevents fiber clumping, and significantly improves the overall performance of the hook-shaped steel fiber concrete. Furthermore, the vibration dispersing mechanism 300 applies vibration to the hook-shaped steel fibers, allowing them to fall evenly and continuously into the mixing chamber 110 through the dispensing holes 325. This mechanism achieves uniform addition of the hook-shaped steel fibers to the concrete, effectively preventing fiber clumping and thus significantly improving the overall performance of the hook-shaped steel fiber concrete.
