Description
Technical Field
[0001] This utility model relates to the field of concrete mixing technology, specifically a concrete mixing device for municipal construction. Background Technology
[0002] Concrete is an indispensable basic material in the construction of municipal roads, bridges, and pipelines. Its mixing quality and efficiency directly affect the project progress and structural strength. As a core piece of construction machinery, concrete mixing equipment is required to mix raw materials such as cement, sand, gravel, and water in proportion to form a homogeneous concrete mixture.
[0003] According to patent document CN220198076U, a high-efficiency concrete mixing device is disclosed, relating to the technical field of high-efficiency concrete mixing stationary equipment. This high-efficiency concrete mixing device includes a box body with a feed inlet on one side of the top and a water inlet on the other side. A mixing device is installed inside the box body, including a motor whose surface penetrates and is fixedly connected to the surface of the box body. A rotating rod is rotatably connected to the inner wall of the box body. Two cylinders are rotatably connected to the two ends of a stop block on the side away from the rotating rod, and mixing blocks are fixedly connected to the surface of the cylinders.
[0004] However, existing concrete mixing equipment for municipal construction has significant shortcomings in the cement feeding and unloading process: First, cement feeding relies on manual handling, requiring operators to carry bagged cement from the ground to the feed inlet of the mixing equipment. This is not only labor-intensive and inefficient, but also prone to damage to the cement bags due to bumps and knocks during handling, causing dust pollution in the early stages. Second, during the unloading process, when cement is poured from the bag to the feed inlet, dry cement powder will be thrown into the air due to gravity and air disturbance, causing dust pollution in the construction environment, harming the respiratory health of operators, and also resulting in cement waste. Utility Model Content

A shelf 207 is fixedly connected to the frame 216. A water tank 208 is fixedly connected to the rear side of the frame 216. A water pump 209 is connected to the bottom left side of the water tank 208. A corrugated pipe 210 is connected to one side of the water pump 209. An atomizing nozzle 211 is connected to one side of the corrugated pipe 210. A collection box 212 is fixedly connected to the top right side of the frame 216. A filter plate 213 is sealed and inserted into the front of the collection box 212. A fan 214 is connected to the right side of the collection box 212. A vacuum head 215 is connected to the left side of the collection box 212. By setting the auxiliary mechanism 2, cement is placed on top of the shelf 207. Then, the drive motor 20 is started by the controller 4. 1. In operation, the drive motor 201 drives the first synchronous pulley 202 to rotate, which, in conjunction with the second synchronous pulley 204, drives the connecting rod 206 to move. The connecting rod 206 then moves the placement plate 207, causing the material to rise. Once the material is above the top of the housing 1, the cement bag opening is opened with a knife, and the cement is poured into the inner cavity of the housing 1. Simultaneously, the controller 4 starts the water pump 209 to extract water from the inner cavity of the water tank 208. The water is then sprayed out through the corrugated pipe 210 and the atomizing nozzle 211, allowing the water mist to contact the cement, thus preventing cement dust. Furthermore, the controller 4 starts the fan 214, which... The suction head 215 sucks in the overflowing material and filters it down through the filter plate 213 for collection. The inner cavity of the second synchronous wheel 204 is fixedly connected to the connecting shaft 205. The front and back of the connecting shaft 205 are movably connected to the frame 216 through bearings. By setting the connecting shaft 205 and bearings, the operation of the second synchronous wheel 204 is stabilized and the second synchronous wheel 204 is limited. The inner cavity of the connecting rod 206 and the shelf 207 is slidably connected to the sliding rod. The top and bottom of the sliding rod are fixedly connected to the frame 216. By setting the sliding rod, the operation of the connecting rod 206 and the shelf 207 is stabilized, thereby facilitating the adjustment of the material height.
[0023] Please see Figure 1 , Figure 3 and Figure 4On the other side of the housing 1, a mixing mechanism 3 is provided. The mixing mechanism 3 includes a dual-shaft motor 301. A stirring roller 302 is fixedly connected to the right output end of the dual-shaft motor 301. A bracket 303 is fixedly connected to the top of the left side of the housing 1. A reciprocating screw 304 is provided on the top of the bracket 303. An adjusting frame 307 is threadedly connected to the surface of the reciprocating screw 304. The bottom of the adjusting frame 307 is fixedly connected to the atomizing nozzle 211. By setting up the mixing mechanism 3, after the material is poured in, the dual-shaft motor 301 is started by the controller 4. The dual-shaft motor 301 drives the stirring roller 302 to rotate, stirring the material. At the same time, it drives the reciprocating screw 304 to rotate. The reciprocating screw 304 drives the adjusting frame 307 to move, which in turn drives the atomizing nozzle 211 to move, thereby achieving the dust reduction effect and avoiding serious dust pollution. The top of the left side of the bracket 303 and the top of the frame 216 are also mentioned. One side of each part is fixedly connected to a fixed seat, and one side of the fixed seat is movably connected to the reciprocating screw 304 through a bearing. By setting the fixed seat and bearing, the operation of the reciprocating screw 304 is stabilized and the reciprocating screw 304 is limited. The left output end of the dual-axis motor 301 and the left side of the reciprocating screw 304 are both fixedly connected to pulleys 305. The surface of the pulleys 305 is fitted with belts 306. By setting pulleys 305 and belts 306, it is convenient for the dual-axis motor 301 to drive the reciprocating screw 304 to rotate, thereby facilitating the movement of the atomizing nozzle 211. The front of the frame 216 and the bottom located at the central axis are fixedly connected to a controller 4. The inner cavity of the adjusting frame 307 is slidably connected to a crossbar, and both sides of the crossbar are fixedly connected to the fixed seat. By setting the crossbar, the operation of the adjusting frame 307 is stabilized and the adjusting frame 307 is balanced and supported.
[0024] Working principle: By setting auxiliary mechanism 2, cement is placed on top of the placement plate 207. Then, the controller 4 starts the drive motor 201. The drive motor 201 drives the first synchronous wheel 202 to rotate. With the cooperation of the second synchronous wheel 204, the connecting rod 206 moves. The connecting rod 206 moves the placement plate 207, which in turn lifts the material. After the material is higher than the top of the shell 1, the cement bag is opened with a knife and the cement is poured into the inner cavity of the shell 1. At the same time, the controller 4 starts the water pump 209 to draw water out of the inner cavity of the water tank 208. The water is sprayed out through the corrugated pipe 210 and the atomizing nozzle 211, so that the water mist comes into contact with the cement, which can play the function of preventing cement dust. In addition, the controller 4 starts the fan 214, which sucks in the overflowing material through the dust suction head 215 and filters it down and collects it through the filter plate 213.
[0025] By setting up the mixing mechanism 3, after the material is poured in, the controller 4 starts the dual-shaft motor 301 to work. The dual-shaft motor 301 drives the mixing roller 302 to rotate, which agitates the material. At the same time, it drives the reciprocating screw 304 to rotate. The reciprocating screw 304 drives the adjusting frame 307 to move, which in turn drives the atomizing nozzle 211 to move, thus achieving the dust reduction effect and avoiding serious dust pollution.
