Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, specifically to a concrete mixing and conveying device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to prevent and control water disasters and to develop and utilize water resources. They mainly include water-related projects in projects such as flood control, drainage, irrigation, water supply, hydropower generation, navigation, water resource protection, soil and water conservation, as well as aquaculture, tourism and ecological environment improvement.

[0003] Currently, in the dam construction of water conservancy projects, it is necessary to first set up a concrete mixing plant at a certain distance from the construction site, and then transport the mixed concrete to the construction site by concrete mixer trucks for dam construction. This will delay the construction progress and reduce the efficiency of the operation. In order to solve the above problems, a concrete mixing and conveying device for water conservancy projects is proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a concrete mixing and conveying device for water conservancy projects, which realizes efficient, continuous and high-quality concrete conveying, and is particularly suitable for dam pouring operations in water conservancy projects.

[0005] To achieve the above objectives, this application provides the following technical solution: a concrete mixing and conveying device for water conservancy projects, comprising a ground surface, a conveying component, a concrete mixing mechanism, a concrete storage mechanism, a tower crane body, and a hoisting hopper. The concrete mixing mechanism includes a concrete mixing tower fixedly connected to the upper surface of the ground surface, a mixing box fixedly connected to the inner wall of the concrete mixing tower, and the concrete storage mechanism being located below the concrete mixing tower.

[0006] The concrete storage mechanism includes a base fixedly connected to the ground surface, a storage box fixedly connected to the upper surface of the base, four second servo motors fixedly connected to the upper surface of the storage box, a second rotating rod fixedly connected to the output end of each second servo motor, a second stirring rod fixedly connected to the outer surface of each second rotating rod, a discharge channel connected to the bottom end of the storage box, a third servo motor fixedly connected to the outer surface of the discharge channel, and a discharge auger fixedly connected to the output end of the third servo motor, the discharge auger being located inside the discharge channel.

[0007] The above scheme utilizes a conveying assembly to transport concrete to a concrete mixing plant for mixing. The mixed concrete is then conveyed to a concrete storage unit. A discharge channel, a third servo motor, and a discharge auger work together to transfer the mixed concrete to a hopper. Finally, a tower crane transports the concrete to the construction site. The concrete storage unit ensures the continuity of concrete mixing, allowing the mixing plant to operate continuously. During the tower crane's transport of concrete to the construction site, if a batch of concrete has been mixed, it can be temporarily stored in the storage unit. The second servo motor is activated to rotate the second rotor and the second mixing rod, continuously agitating the concrete inside the storage tank to prevent quality degradation due to prolonged waiting time. Meanwhile, the mixing plant can continue mixing the next batch of concrete, making the system more practical.

[0008] Furthermore, both the conveying assembly and the tower crane body are installed on the upper surface of the ground, the hoisting hopper is adapted to the tower crane body, and the hoisting hopper is placed below the output end of the discharge channel.

[0009] The above scheme defines the relationship between the tower crane body and the hoisting hopper, so that the tower crane body can use the hoisting hopper to lift the concrete transported through the discharge channel to the construction site for dam pouring operations.

[0010] Furthermore, a feeding port is provided at the top of the mixing box, and the position of the feeding port corresponds to the position of the top of the conveying component. A first servo motor is fixedly connected to the upper surface of the mixing box, and a first rotating rod is fixedly connected to the output end of the first servo motor.

[0011] With the above scheme, the concrete raw materials conveyed by the conveying component can fall directly into the mixing box through the feeding port, and when the first servo motor is started, it can drive the first rotating rod to rotate.

[0012] Furthermore, a plurality of first stirring rods are fixedly connected to the outer surface of the first rotating rod, and three mixing rods are fixedly connected to the top of the first rotating rod.

[0013] With the above scheme, when the first rotating rod rotates, the first stirring rod and the mixing rod can rotate, thereby enabling the concrete inside the mixing box to be mixed evenly.

[0014] Furthermore, the bottom of the mixing tank is connected to a discharge port, and a valve is installed inside the discharge port.

[0015] With the above method, when the valve is opened, the concrete inside the mixing tank will fall into the storage tank through the discharge port.

[0016] Furthermore, the top of the mixing tank is connected to two external pipes.

[0017] The above-mentioned solution allows the external pipelines to be connected to external water sources and other equipment, enabling the direct delivery of water and other raw materials to the mixing tank, which is beneficial to the concrete mixing process.

[0018] Furthermore, a first rain shelter is fixedly connected to the top of the concrete mixing plant, the mixing box is located below the first rain shelter, a second rain shelter is fixedly connected to the upper surface of the ground, the conveying assembly is located below the second rain shelter, and the top of the second rain shelter is fixedly connected to the outer surface of the first rain shelter.

[0019] The above scheme, with the first and second rain shelters working together, can provide rain protection and allow concrete mixing to be carried out even on rainy days.

[0020] Furthermore, two reinforcing plates are fixedly connected to the outer surface of the concrete mixing plant, and the other ends of the two reinforcing plates are respectively fixedly connected to both sides of the outer surface of the conveying component.

[0021] The above-mentioned solution can improve the stability of the conveying assembly, thereby enabling the conveying assembly to transport the concrete for mixing more stably.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This is a concrete mixing and conveying device for water conservancy projects. A conveying assembly transports concrete to a concrete mixing unit for mixing. The mixed concrete is then conveyed to a concrete storage unit. A discharge channel, a third servo motor, and a discharge auger work together to transfer the mixed concrete to a hopper. A tower crane then transports the concrete to the construction site. The concrete storage unit ensures the continuity of concrete mixing, allowing the mixing unit to operate continuously. During the tower crane's transport of concrete to the construction site, if a batch of concrete has been mixed, it can be temporarily stored in the storage unit. The second servo motor is activated to rotate the second rotating rod and the second mixing rod, continuously agitating the concrete inside the storage tank to prevent quality degradation due to prolonged waiting time. The mixing unit can then continue mixing the next batch of concrete, making it more practical. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 4This embodiment of a concrete mixing and conveying device for hydraulic engineering includes a ground surface 1, a conveying assembly 2, a concrete mixing mechanism 3, a concrete storage mechanism 4, a tower crane body 5, and a hoisting hopper 6. The concrete mixing mechanism 3 includes a concrete mixing tower 301 fixedly connected to the upper surface of the ground surface 1. A mixing tank 302 is fixedly connected to the inner wall of the concrete mixing tower 301. A feeding port 303 is opened at the top of the mixing tank 302, and the position of the feeding port 303 corresponds to the position of the top of the conveying assembly 2. The concrete raw materials conveyed by the conveying assembly 2 can fall directly into the mixing tank 302 through the feeding port 303. A first servo motor 304 is fixedly connected to the upper surface of the mixing tank 302. The output end is fixedly connected to a first rotating rod 305. When the first servo motor 304 starts, it can drive the first rotating rod 305 to rotate. Multiple first stirring rods 306 are fixedly connected to the outer surface of the first rotating rod 305. Three mixing rods 307 are fixedly connected to the top of the first rotating rod 305. When the first rotating rod 305 rotates, it can make the first stirring rods 306 and mixing rods 307 rotate, thereby enabling the concrete inside the mixing box 302 to be mixed evenly. The top of the mixing box 302 is connected to two external pipes 310. Through the external pipes 310, it can be connected to external water sources and other equipment, and water and other raw materials can be directly transported into the mixing box 302, which is beneficial to the concrete mixing work.

[0033] Please see Figure 1 , Figure 4 and Figure 5The concrete storage mechanism 4 is located below the concrete mixing plant 301. The concrete storage mechanism 4 includes a base 401 fixedly connected to the upper surface of the ground 1. A storage tank 402 is fixedly connected to the upper surface of the base 401. The bottom end of the mixing plant 302 is connected to a discharge port 308. A valve 309 is installed inside the discharge port 308. When the valve 309 is opened, the concrete inside the mixing plant 302 falls into the storage tank 402 through the discharge port 308. Therefore, the storage tank 402 can serve as a temporary transfer point for concrete. Four second servo motors 403 are fixedly connected to the upper surface of the storage tank 402. A second rotating rod 404 is fixedly connected to the output end of each second servo motor 403. A second mixing rod 405 is fixedly connected to the outer surface of each second rotating rod 404. When the second servo motor 403 is started, it can pass through the second rotating rod... 404 drives the second stirring rod 405 to rotate. The rotation of the second stirring rod 405 can agitate the concrete inside the storage tank 402 again, avoiding problems such as segregation and initial setting of the concrete stored in the storage tank 402, thus ensuring the storage quality of the concrete. The bottom end of the storage tank 402 is connected to the discharge channel 406. The outer surface of the discharge channel 406 is fixedly connected to the third servo motor 407. The output end of the third servo motor 407 is fixedly connected to the discharge auger 408. The discharge auger 408 is located inside the discharge channel 406. When the third servo motor 407 is started, it can drive the discharge auger 408 to rotate. When the discharge auger 408 rotates, it can transport the concrete inside the storage tank 402 through the discharge channel 406. Finally, the concrete is input into the hanging tank hopper 6 through the output end of the discharge channel 406 for use.

[0034] It should be noted that the concrete storage mechanism 4 can temporarily store the mixed concrete, ensuring that the concrete mixing mechanism 3 can produce continuously without waiting for the conveying component 2 to complete the transportation task before mixing the next batch of concrete.

[0035] Please see Figure 1 , Figure 2 and Figure 3The conveying assembly 2 and the tower crane body 5 are both installed on the upper surface of the ground 1. The hoisting hopper 6 is adapted to the tower crane body 5 and is placed below the output end of the discharge channel 406, defining the relationship between the tower crane body 5 and the hoisting hopper 6. In this way, the tower crane body 5 can use the hoisting hopper 6 to lift the concrete conveyed through the discharge channel 406 to the construction site for dam pouring operations. The top of the concrete mixing plant 301 is fixedly connected to a first rain shelter 7, and the mixing box 302 is located below the first rain shelter 7. The upper surface of the ground 1 is fixedly connected to a second rain shelter 8. 2 is located below the second rain shelter 8, and the top of the second rain shelter 8 is fixedly connected to the outer surface of the first rain shelter 7. The first rain shelter 7 and the second rain shelter 8 work together to achieve the effect of rain protection, so that concrete mixing can be carried out in rainy weather. Two reinforcing plates 9 are fixedly connected to the outer surface of the concrete mixing tower 301. The other ends of the two reinforcing plates 9 are fixedly connected to both sides of the outer surface of the conveying component 2. The reinforcing plates 9 can improve the stability of the conveying component 2, so that the conveying component 2 can convey the concrete for mixing more stably.

[0036] In this embodiment, a concrete mixing and conveying device for water conservancy projects can transport concrete to a concrete mixing unit 3 for mixing via a conveying component 2. The concrete mixed by the concrete mixing unit 3 can be conveyed to a concrete storage unit 4. The mixed concrete can be transferred to a hoisting hopper 6 through the cooperation of a discharge channel 406, a third servo motor 407, and a discharge auger 408. Then, the concrete is transported to the construction site by a tower crane body 5. The concrete storage unit 4 can also ensure the continuity of concrete mixing by the concrete mixing unit 3, ensuring that the concrete mixing unit 3 can work continuously. During the process of the tower crane body 5 transporting concrete to the construction site, if the concrete mixing unit 3 has mixed a batch of concrete, it can be temporarily stored in the concrete storage unit 4. The second servo motor 403 is started to rotate the second rotating rod 404 and the second stirring rod 405 to continuously stir the concrete inside the storage tank 402, preventing the concrete from deteriorating in quality due to long waiting time. The concrete mixing unit 3 can continue to mix the next batch of concrete, making it more practical.

[0037] It should be noted that the conveying component 2 and the concrete mixing unit 3 can be set up near the construction site to be responsible for mixing and producing concrete for dam pouring operations. This reduces the transportation distance of concrete and avoids the time delays caused by long-distance transportation by traditional mixer trucks. The working range of the tower crane body 5 can cover the concrete mixing unit 3 and the dam pouring construction site. The tower crane body 5 can lift the concrete conveyed by the discharge channel 406 to the construction site for dam pouring operations through the hoisting hopper 6. The combination of the tower crane body 5 and the hoisting hopper 6 can quickly transport concrete from the discharge channel 406 to the pouring site, reducing the waiting time in the intermediate links.

[0038] The working principle of the above embodiment is as follows: Concrete can be conveyed to the top of the mixing tank 302 through the conveying component 2, and then fall into the mixing tank 302 through the feeding port 303. At the same time, the liquid materials required for mixing can be added to the mixing tank 302 through the external pipe 310. Then, the first servo motor 304 can be started to rotate the first stirring rod 306 and the mixing rod 307 to mix the raw materials inside the mixing tank 302. After the concrete mixing is completed, the valve 309 can be opened to allow the concrete inside the mixing tank 302 to be conveyed to the storage tank 402 through the discharge port 308. Then, the third servo motor 407 is started to rotate the discharge auger 408, so that the concrete inside the storage tank 402 can be pushed by the rotation of the discharge auger 408, and the concrete can be conveyed along the discharge channel 406. The concrete is fed into the hoisting hopper 6, and then the tower crane body 5 can lift the hoisting hopper 6 to the construction site for dam pouring. Then, the above steps are repeated. If the concrete in the mixing tank 302 has been mixed, but the tower crane body 5 and the hoisting hopper 6 are still pouring, then the four second servo motors 403 can be started and the third servo motor 407 can be stopped. When the four second servo motors 403 are started, the second rotating rod 404 and the second mixing rod 405 can be rotated. The rotation of the second mixing rod 405 can agitate the concrete inside the storage tank 402, preventing the concrete from deteriorating in quality due to long waiting time. At this time, the concrete storage mechanism 4 can serve as a temporary storage unit, while the concrete mixing mechanism 3 can continue to mix the next batch of concrete, making it more practical.
