Description

Technical Field

[0001] This utility model relates to the technical field of concrete production equipment, and in particular to a dust-free mixing equipment for concrete production. Background Technology

[0002] Concrete, as one of the most important civil engineering materials in modern society, is widely used in many industries and fields due to its excellent compressive strength, outstanding durability and wide range of strength grades. Whether it is the construction of high-rise buildings or the construction of bridges and roads, concrete plays an irreplaceable role.

[0003] A search revealed Chinese Patent Publication No. CN221872526U, which discloses a dust-free concrete production device, belonging to the technical field of concrete production devices. This device solves the technical problem of existing concrete production devices easily causing blockages and generating large amounts of dust during raw material addition. The device includes a frame with a feeding section and a mixing section. The feeding section includes a feeding box with a partition connecting it, dividing the feeding box into a first feeding chamber and a second feeding chamber. The feeding box is also connected to a first feeding hopper and a second feeding hopper, each containing a feeding assembly. A transmission assembly is also connected to the feeding box. A first rotating plate and a second rotating plate are rotatably connected to the bottom of the first and second feeding hoppers. A first motor and a second motor are also connected to the feeding box. Weight sensors are connected to both the first and second rotating plates. A water storage chamber is also provided inside the feeding box, with several nozzles connected to its exterior. The water storage chamber is also connected to a water inlet pipe. However, in actual use, the above-mentioned device has the following problems: in order to ensure convenient transportation of lime powder, it is usually packaged in bags. The lime powder is poured into the mixing tank by opening the bag. However, this will cause a large amount of dust to float in the air when the lime powder is poured in, which will eventually affect the health of workers and pollute the surrounding environment. Therefore, a dust-free mixing equipment for concrete production is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dust-free mixing equipment for concrete production, which aims to improve the problem in the prior art where a large amount of dust floats in the air when lime powder is poured into the mixing tank, directly affecting the health of workers and polluting the surrounding environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust-free concrete mixing device, comprising a feeding box, a mixing drum, and a sealing cover. A fixing plate is fixedly connected to the top right side of the feeding box, and a sealing plate is rotatably connected to the left side of the fixing plate. Inclined plates are fixedly connected to both the left and right sides inside the feeding box, and barbs are fixedly connected to the top of the inclined plates. A limiting rod is fixedly connected to the inside of the feeding box, and a sliding plate is slidably connected to the outer wall of the limiting rod. A cutting blade is fixedly connected to the right side of the sliding plate. An electric push rod is fixedly connected to the front side of the feeding box, and one end of the electric push rod passes through the front side of the feeding box and is fixedly connected to the front side of the sliding plate. A collecting plate is fixedly connected to the inside of the feeding box. A screw feeding device is installed on the right side of the feeding box. A mixing assembly is provided inside the mixing drum, and a cleaning mechanism is provided inside the mixing drum.

[0006] The above technical solution involves placing packaged lime in the feeding hopper and closing the sealing plate to ensure a sealed space. At this time, the barbs on the inclined plate will puncture the packaging bag. Simultaneously, the electric push rod is activated to drive the sliding plate to slide back and forth, causing the cutting blade to cut open the bottom of the packaging bag. The vibration motor is then activated to allow the lime inside to flow rapidly into the bottom of the feeding hopper. Finally, the lime is transferred to the mixing tank by the screw feeder, completing the dust-free feeding process throughout.

[0007] As a further description of the above technical solution: The cleaning mechanism includes a first connecting plate, which is fixedly connected to the front side of the outer wall of the mixing tank. A folding inner cylinder plate is slidably connected to the inner side of the mixing tank. A limit plate is fixedly connected to the top of the folding inner cylinder plate. A second connecting plate is fixedly connected to the front side of the outer wall of the folding inner cylinder plate. A connecting bolt is threaded to the top of each of the two second connecting plates. The inner wall of the folding inner cylinder plate is coated with polytetrafluoroethylene.

[0008] Through the above technical solution: the folding inner cylinder plates can be folded together to form a cylindrical shape. The flipping between them allows the inner corners to fit together, preventing material leakage. The folded inner cylinder plates are installed in the mixing tank, and the connecting plates are reinforced with connecting bolts. After the concrete is processed, the folding inner cylinder plates are removed and unfolded. At this time, the surface concrete will slide off the surface, and the polytetrafluoroethylene coating on the surface can better prevent concrete adhesion and improve internal cleanliness.

[0009] As a further description of the above technical solution: The stirring assembly includes a servo motor, which is fixedly connected to the top of the sealing cover. The output end of the servo motor passes through the top of the sealing cover and is fixedly connected to a stirring rod.

[0010] The above technical solution enables the servo motor to drive the mixing rod to rotate at high speed. The shape design of the mixing rod allows for thorough mixing of the internal concrete.

[0011] As a further description of the above technical solution: The outer wall of the mixing tank is fixedly connected with fasteners, and the outer wall of the sealing cover is fixedly connected with buckles.

[0012] The above technical solution, through the cooperation of the buckle and the fastener, ensures the tightness between the sealing cover and the mixing tank, thus preventing material leakage.

[0013] As a further description of the above technical solution: The bottom of the mixing tank is fixedly connected to a support frame, and the bottom end of the support frame is fixedly connected to a rubber pad.

[0014] Through the above technical solution, the support frame provides good support for the entire device and a stable platform.

[0015] As a further description of the above technical solution: The bottom of the mixing tank is connected to a discharge valve, and a collection box is slidably connected inside the support frame.

[0016] Through the above technical solution, the discharge valve can control the discharge of internal materials, and the discharged materials can be stored in a collection box for subsequent use.

[0017] As a further description of the above technical solution: A controller is fixedly connected to the front of the feed box. The controller is electrically connected to the electric push rod, the screw feeder, the servo motor and the discharge valve.

[0018] The above technical solution allows for convenient and simple operation and control of the operating equipment throughout the entire device via a controller.

[0019] As a further description of the above technical solution: A reinforcing plate is fixedly connected to the bottom of the controller, and the rear side of the reinforcing plate is fixedly connected to the front side of the feed box.

[0020] The above technical solution ensures the controller's stability during vibration operation by supporting and fixing it with a reinforcing plate.

[0021] This utility model has the following beneficial effects: 1. In this utility model, after the packaged lime is placed on the inclined plate through the feeding box, the sealing plate is closed, the packaged lime will be punctured by barbs and stop at the designated position. The sliding plate is driven by the start of the electric push rod to slide. At the same time, the cutting blade will cut the bottom of the packaging bag, allowing the material to flow out. The falling material is collected by the collecting plate and flows to the right. With the cooperation of the screw feeding device, the material is conveyed into the mixing tank in a dust-free manner, and the dust-free feeding process is completed throughout the process.

[0022] 2. In this utility model, the folded inner cylinder plates are bent inwards to form a circular inner barrel. The limiting plate fixes the folded inner cylinder plates in the accurate position inside the mixing tank. When the internal concrete hardens after processing or when cleaning is required, the folded inner cylinder plates can be directly removed and unfolded. This can remove the cracked concrete. At the same time, the polytetrafluoroethylene coating on the inner wall of the folded inner cylinder plates can effectively prevent the adhesion of substances and improve cleaning efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a dust-free concrete mixing device, comprising a feeding box 1, a mixing tank 3, and a sealing cover 4. A fixing plate 5 is fixedly connected to the top right side of the feeding box 1, and a sealing plate 6 is rotatably connected to the left side of the fixing plate 5. The fixing plate 5 and the sealing plate 6 can form a sealed space inside the feeding box 1 to prevent dust leakage. Inclined plates 7 are fixedly connected to both the left and right sides inside the feeding box 1. Barbs 8 are fixedly connected to the top of the inclined plates 7. The inclined surface design of the inclined plates 7 allows the packaged lime to accurately stop between them. A feeding gap is reserved between the inclined plates 7. When the packaged lime is placed on the inclined plates 7, the packaged lime will be punctured by the barbs 8 and stop at the designated position, improving stability and subsequent bag retrieval. A limiting rod 9 is fixedly connected inside the feeding box 1. A sliding plate 10 is slidably connected to the outer wall of the limiting rod 9. A cutting blade 11 is fixedly connected to the right side of the sliding plate 10. An electric push rod 12 is fixedly connected to the front side of the feeding box 1, and one end of the electric push rod 12 passes through the feeding box. The front side of the box 1 is fixedly connected to the front side of the sliding plate 10. By starting the electric push rod 12, the sliding plate 10 can be driven to slide back and forth on the outer wall of the limit rod 9. While sliding, the bottom of the packaging bag is cut by the cutting blade 11, so that the material flows out. If you want to improve the feeding effect, a vibration motor can be installed on the outside of the feeding box 1 to increase the feeding speed. The inner side of the feeding box 1 is fixedly connected to the collecting plate 13. The right side of the feeding box 1 is equipped with a screw feeding device 14. The mixing tank 3 is equipped with a mixing component. The falling material flows to the right through the collecting plate 13. With the cooperation of the screw feeding device 14, the material is transported into the mixing tank 3 without dust. The mixing tank 3 is equipped with a cleaning mechanism 2. The mixing component includes a servo motor 15. The servo motor 15 is fixedly connected to the top of the sealing cover 4. The output end of the servo motor 15 passes through the top of the sealing cover 4 and is fixedly connected to the mixing rod 16. Finally, by starting the servo motor 15, the mixing rod 16 is driven to fully mix the concrete. Specifically, the feeding box 1, mixing tank 3, and sealing cover 4 form a sealed space, effectively preventing dust leakage. To further ensure accurate material feeding, inclined plates 7 are fixed on both the left and right sides inside the feeding box 1. Barbs 8 are fixedly connected to the top of the inclined plates 7. This inclined design allows the packaged lime to accurately stop between the two plates. A feeding gap is reserved between the inclined plates 7. When packaged lime is placed on the inclined plates 7, it will be punctured by the barbs 8 and stop at the designated position. This not only improves stability and the convenience of subsequent bag retrieval, but also, to further control material feeding, a limit rod 9 is fixed inside the feeding box 1. A sliding plate 10 slides on the outer wall of the limiting rod 9. A cutting blade 11 is fixed on the right side of the sliding plate 10 to cut the bottom of the packaging bag and allow the material to flow out. If the feeding effect needs to be improved, a vibration motor needs to be installed on the outside of the feeding box 1 to increase the feeding speed. In addition, a collecting plate 13 is fixed on the inner side of the feeding box 1, and a screw conveyor 14 is installed on the right side of the feeding box 1. The falling material flows to the right through the collecting plate 13. With the cooperation of the screw conveyor 14, the material is conveyed into the mixing tank 3 without dust. Finally, the servo motor 15 is started to drive the mixing rod 16 to fully mix the concrete, thereby ensuring the quality of the concrete and the production efficiency.

[0027] Reference Figure 1 , Figure 4 and Figure 5 The cleaning mechanism 2 includes a connecting plate 201, which is fixedly connected to the front side of the outer wall of the mixing tank 3. The connecting plate 201 is welded to the front side of the mixing tank 3. A folding inner cylinder plate 202 is slidably connected to the inner side of the mixing tank 3. The folding inner cylinder plate 202 is made of multiple arc-shaped plates and hinges connected to each other. When the folding inner cylinder plate 202 bends inward, it forms a circular inner cylinder for mixing the internal concrete and protecting the inner wall of the mixing tank 3. A limiting plate 203 is fixedly connected to the top of the folding inner cylinder plate 202. The limiting plate 203 can fix the folding inner cylinder plate 202 in an accurate position inside the mixing tank 3. Connecting plates 204 are fixedly connected to the front side of the outer wall of the folding inner cylinder plate 202. The top of 204 is threaded with connecting bolts 205, and the connecting plate 201 and the connecting plate 204 are reinforced by the connecting bolts 205. The inner wall of the folding inner cylinder plate 202 is coated with polytetrafluoroethylene 206. When the internal concrete hardens after processing or when cleaning is required, the folding inner cylinder plate 202 can be directly removed and unfolded to remove the cracked concrete. At the same time, the inner wall of the folding inner cylinder plate 202 is coated with polytetrafluoroethylene 206, which can effectively prevent the adhesion of substances and improve cleaning efficiency. The outer wall of the mixing tank 3 is fixedly connected with fasteners 17, and the outer wall of the sealing cover 4 is fixedly connected with buckles 18. Specifically, the connecting plate 201 is tightly welded to the front of the mixing drum 3. A folding inner cylinder plate 202 is slidably installed inside the mixing drum 3. This folding inner cylinder plate 202 is composed of multiple curved plates cleverly connected by hinges. When these folding inner cylinder plates 202 bend inwards, they form a circular inner drum shape. This shape is crucial for mixing the concrete inside, as it not only effectively mixes the concrete but also forms a protective layer on the inner wall of the mixing drum 3. To ensure the accurate position of the folding inner cylinder plate 202 inside the mixing drum 3, a limiting plate 203 is fixedly connected to its top. The function of the limiting plate 203 is to ensure the stability of the folding inner cylinder plate 202 inside the mixing drum 3. For precise positioning, the connecting plate 204 is connected to the top by a connecting bolt 205 via a thread. The connecting bolt 205 further reinforces the connection between the connecting plate 1 201 and the connecting plate 204, enhancing the structural stability of the entire cleaning mechanism 2. To further improve the performance of the mixing tank 3, the inner wall of the folding inner cylinder plate 202 is specially coated with a polytetrafluoroethylene coating 206. This coating has excellent anti-adhesion properties. When the internal concrete hardens or needs to be cleaned immediately, the folding inner cylinder plate 202 can be directly removed from the mixing tank 3 and unfolded, which can easily remove the cracked concrete. The presence of the polytetrafluoroethylene coating 206 not only improves the cleaning efficiency but also reduces the problem of material adhesion during the cleaning process.

[0028] Reference Figure 1 and Figure 2 A support frame 19 is fixedly connected to the bottom of the mixing tank 3. Rubber pads 20 are fixedly connected to the bottom of the support frame 19. A discharge valve 21 is connected to the bottom of the mixing tank 3. A collection box 22 is slidably connected inside the support frame 19. A controller 23 is fixedly connected to the front of the feed box 1. The controller 23 is electrically connected to the electric push rod 12, the screw feeder 14, the servo motor 15 and the discharge valve 21 respectively. The controller 23 facilitates simple operation and control of the operating equipment on the entire device. A reinforcing plate 24 is fixedly connected to the bottom of the controller 23. The rear side of the reinforcing plate 24 is fixedly connected to the front side of the feed box 1. The controller 23 is reinforced by the reinforcing plate 24 to ensure the firmness of the controller 23. Specifically, the bottom of the mixing tank 3 is supported by the support frame 19 to ensure the stability of the mixing tank 3 during operation. The bottom of the mixing tank 3 is also connected to the discharge valve 21 for discharging materials after mixing. The support frame 19 is designed with a collection box 22 to facilitate the collection of any overflow materials generated during the mixing process. The front side of the feed box 1 is fixed with a controller 23. Through the controller 23, the operator can easily perform simple operation control, making the entire workflow more efficient and convenient.

[0029] Working principle: First, the packaged lime is placed on the inclined plate 7 through the feed box 1, and then the sealing plate 6 is closed. The fixing plate 5 and the sealing plate 6 can form a sealed space inside the feed box 1. At the same time, the packaged lime will be punctured by the barbs 8 and stay in the designated position. After the material is discharged, it is easy to pick up the packaged bag. The sliding plate 10 is driven to slide on the outer wall of the limit rod 9 by starting the electric push rod 12. While sliding, the bottom of the packaged bag is cut by the cutting blade 11 to allow the material to flow out. If you want to improve the feeding effect, a vibration motor can be installed on the outside of the feed box 1 to increase the feeding speed. The falling material is concentrated and flows to the right by the collecting plate 13. With the cooperation of the screw feeder 14, the material is transported into the mixing tank 3 without dust. Finally, the mixing rod 16 is driven by starting the servo motor 15 to fully mix the concrete. Furthermore, by bending the inner folding plates 202 inwards, a circular inner barrel is formed, which is used to mix the concrete inside and protect the inner wall of the mixing tank 3. The limiting plate 203 is engaged with the top of the mixing tank 3, so that the inner folding plates 202 are fixed in the accurate position inside the mixing tank 3. When the concrete inside hardens after processing or when cleaning is required, the inner folding plates 202 can be directly removed and unfolded. This can remove the cracked concrete. At the same time, the polytetrafluoroethylene coating 206 on the inner wall of the inner folding plates 202 can effectively prevent the adhesion of substances and improve the cleaning efficiency.
