Description
Technical Field
[0001] The utility model relates to the technical field of concrete production, in particular to a sand and gravel concrete mixing device provided with a noise reduction and dust removal structure. Background Art
[0002] Concrete is a composite material widely used in construction projects. It is primarily composed of cement, sand, gravel, and water. Concrete production requires a mixing device, which is a device used to mix the various concrete components in a specific ratio. Its purpose is to ensure the uniformity and quality of the concrete.
[0003] At present, there are still some deficiencies in the sand and gravel concrete mixing device, such as the inability to handle the dust raised during the feeding process:
[0004] To overcome the raised dust, a Chinese patent in the prior art (publication number: CN218138992U) discloses a concrete production premixing device. By providing a mixed material discharge assembly, the device can quickly and conveniently mix the screened sand and gravel, improving the convenience of sand and gravel mixing, ensuring work quality, and improving production efficiency. At the same time, the guide plate can be opened to remove the material, ensuring the convenience of removing the material, saving human resources, improving work quality, and reducing labor costs. By providing a feeding dust reduction assembly, the dust can be sucked into the collection box for treatment through an exhaust fan during feeding, ensuring the health of workers.
[0005] However, the concrete mixing devices currently used still have certain shortcomings. The above-mentioned document achieves the purpose of dust reduction by extracting dust, but the workload of concrete is relatively large, and the amount of dust that needs to be absorbed is also relatively large. It should be suppressed and the dust should be mixed with concrete to reduce material costs. Secondly, concrete production will generate noise and affect the surrounding environment, so the existing structure needs to be improved. Utility Model Content

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Example 1:
[0031] like Figures 1-6 The technical solution shown in the figure, the utility model provides the following technical solution: In order to solve the problem that the mixing device generates noise during the stirring process and affects the surrounding environment, a noise reduction mechanism is disclosed:
[0032] The base 1 includes a base 1, an output device 2 is connected to the inner side of the base 1, a material box 3 is connected to the inner side of the base 1 away from the output device 2, a stirrer 4 is rotatably connected inside the material box 3, and the stirrer 4 is fixed to the side of the output device 2. The first sound absorbing plate 301 and the second sound absorbing plate 302 are connected to the two sides of the material box 3 respectively. The first sound absorbing plate 301 and the second sound absorbing plate 302 are both provided with a through groove 303 on the side. There are four through grooves 303 on the side of the first sound absorbing plate 301 and the second sound absorbing plate 302 respectively. Fixed blocks 304 are fixed on both sides of the material box 3. The fixed blocks 304 slide through the through grooves 303. A mixing reduction device is provided inside the fixed blocks 304. Noise reduction mechanism, a second external block 314 is symmetrically fixed to the side of the second sound-absorbing plate 302, an atomizer 315 is rotatably connected inside the second external block 314, and a spray mechanism for reducing loading dust is also provided on the side of the material box 3. The noise reduction mechanism includes a telescopic slot 305, which is opened through the upper surface of the fixed block 304, a spring 306 is connected inside the telescopic slot 305, and a telescopic block 307 is connected to the top of the spring 306, and the telescopic block 307 slides through the telescopic slot 305. An extrusion block 308 slides through the inner side of the telescopic slot 305 away from the material box 3, and an extrusion slot 309 is provided on the side of the telescopic block 307 close to the extrusion block 308;
[0033] When the mixing device is in use, the materials needed for concrete are placed inside the material box 3, and then the output device 2 is started to drive the stirrer 4 inside the material box 3 to rotate. When the stirrer 4 rotates, the materials inside the material box 3 can be mixed and stirred. When the concrete is stirred, friction will occur between the material itself and the material and the inner wall of the material box 3. The friction caused by stirring will generate noise. The first sound absorbing panel 301 and the second sound absorbing panel 302 can be moved to the side of the material box 3 respectively for fitting. When the first sound absorbing panel 301 and the second sound absorbing panel 302 are fitted, they can drive the through groove 303 to move. When the through groove 303 moves to the side of the fixed block 304, it can be inserted. By inserting the first sound absorbing panel 301 and the second sound absorbing panel 302, they can be fitted against each other. On the side of the material box 3, the first sound-absorbing panel 301 and the second sound-absorbing panel 302 are abutted against each other, and the extrusion block 308 inside the fixed block 304 is pulled. When the extrusion block 308 is pulled, it can leave the extrusion groove 309. After the extrusion block 308 leaves, the telescopic block 307 has no resistance. At this time, the spring 306 can push the telescopic block 307 upward by its own elastic force. When the telescopic block 307 moves, it can slide through the telescopic groove 305. The telescopic block 307 can slide to the back of the first sound-absorbing panel 301 and the second sound-absorbing panel 302 for positioning. After the first sound-absorbing panel 301 and the second sound-absorbing panel 302 are positioned, their own materials can absorb the stirring noise inside the base 1, thereby reducing the noise caused by the operation of the mixing device.
[0034] Example 2:
[0035] like Figure 3 and Figure 4 The technical solution shown in the figure, the utility model provides the following technical solution: In order to solve the problem that the feeding port of the mixing device is prone to loud noise, based on the embodiment 1, a closing mechanism is disclosed:
[0036] A closing mechanism for reducing the noise of material stirring is also provided on the side of the material box 3. The closing mechanism includes a first external block 310, which is fixed to the side of the first sound-absorbing plate 301. The first external block 310 is fixed with three groups. The first external block 310 is internally connected to a rotating block 311 for rotation. A third sound-absorbing plate 312 is fixed to the side of the rotating block 311. During the operation of the mixing device, pushing the third sound-absorbing plate 312 can drive the rotating block 311 to rotate. When the rotating block 311 rotates, it can rotate through the first external block 310. When the third sound-absorbing plate 312 rotates to the top of the material box 3, the opening can be closed. The noise emitted at the opening of the material box 3 can be absorbed by the third sound-absorbing plate 312, further reducing the noise pollution of the mixing device and improving the user experience of the device.
[0037] Example 3:
[0038] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7 The technical solution shown in the figure, the utility model provides the following technical solution: In order to solve the problem that the mixing device generates dust when loading, which affects the health of the operator, a spray mechanism is disclosed:
[0039] The spray mechanism includes a first rotating rod 313, which is fixed to the side of the rotating block 311. The first rotating rod 313 rotates through the first external block 310. A second rotating rod 316 is fixed to the side of the atomizer 315. The second rotating rod 316 rotates through the second external block 314. Pulleys 317 are fixed to the ends of the second rotating rod 316 and the first rotating rod 313. A transmission belt 318 is connected between the pulleys 317. The back of the atomizer 315 rotates. The bottom of the mixing device is connected to a connecting pipe 319, and the bottom of the connecting pipe 319 is connected to a water pump. The water pump is installed on the inside of the base 1. The water inlet of the water pump is connected to a water suction pipe 320. The end of the water suction pipe 320 will be connected to the water pool. Before using the mixing device, it is necessary to load the material from the opening of the material box 3. Before loading, it is necessary to rotate the third sound-absorbing plate 312 to open the feed port of the material box 3. When the third sound-absorbing plate 312 rotates, it can drive the rotating block 311 to rotate through the first external block 310. The rotating block 311 rotates When the first rotating rod 313 rotates, the first rotating rod 313 can drive the pulley 317 to rotate. When the pulley 317 rotates, it can drive another pulley 317 to rotate through the transmission belt 318. When the other pulley 317 rotates, it can drive the second rotating rod 316 to rotate. When the second rotating rod 316 rotates, it can rotate through the second external block 314. When the second rotating rod 316 rotates, it can drive the atomizer 315 to rotate. When the third sound-absorbing panel 312 rotates from the feeding port of the material box 3 to the side of the first sound-absorbing panel 301, the atomizer 315 can rotate from the side of the second sound-absorbing panel 302 to the top. At this time, the water pump is started. The water inlet of the water pump can draw water from the water pool through the suction pipe 320. The water pump then transports the water to the inside of the atomizer 315 through the connecting pipe 319. The atomizer 315 breaks up the water and sprays it in the form of mist. When the water is sprayed, the dust generated by the loading can be suppressed, thereby achieving the dust removal effect of the mixing device.
