Moreover, a lot of dust is generated when pouring cement, which is harmful to the health of workers. Relying solely on manual feeding of the mixing hopper cannot guarantee the stability of the cement slurry mix ratio. Therefore, an automated feeding device for high-pressure jet grouting piles is proposed to solve the above problems. Utility Model Content

[0016] 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.

[0017] Reference Figure 1-4The high-pressure jet grouting pile automated feeding device includes a base plate 1, two top plates 2 fixedly installed on the top side of the base plate 1, a conveyor belt 3 between the two top plates 2, a dust cover 4 fixedly connected to the top side of the two top plates 2, a dust suppression component on one side of the dust cover 4, a through hole on one side of the dust cover 4, a fixed column 12 fixedly installed in the through hole, a lever 13 movably sleeved on the outside of the fixed column 12, a fixed frame 14 and a funnel 16 fixedly connected to the bottom side of the lever 13, a counterweight 15 placed in the fixed frame 14, and the funnel 16 located on one side of the conveyor belt 3. A discharge port 17 is provided on the bottom side, and a discharge mixing assembly is installed inside the discharge port 17. A pushing assembly is provided on one side of the bottom plate 1. The discharge mixing assembly includes a motor 18 fixedly installed on the bottom side of a dust cover 4. The output end of the motor 18 rotates through the dust cover 4 and is fixedly connected to a rotating rod 19. Multiple mixing rods 20 are fixedly connected to the outside of the rotating rod 19. A part of the rotating rod 19 is located inside the funnel 16. A spiral blade 22 and a baffle 21 are fixedly sleeved on the top of the rotating rod 19. The bottom side of the baffle 21 is in contact with the inner wall of the bottom side of the funnel 16. The material is placed on the fixed frame 14. Multiple counterweights 15 are placed on the fixed frame 14. The amount of cement to be mixed can be referenced based on the counterweights 15. When a specific weight of cement needs to be mixed, only the counterweights 15 are placed on the fixed frame 14. At this time, the right side of the lever 13 will move downward under the gravity of the counterweights 15, while the left end will tilt upward. As the funnel 16 tilts upward, the discharge port 17 opened on the bottom inner wall of the funnel 16 will fit against the bottom side of the baffle 21. The baffle 21 can block the cement and prevent it from overflowing directly from the discharge port 17, thus affecting the subsequent mixing ratio. As cement is continuously delivered, the weight of the funnel 16 will exceed the weight of the counterweight 15, causing the left end of the lever 13 to move downwards. At this time, the discharge port 17 will be removed from the obstruction of the baffle 21, allowing the cement in the funnel 16 to fall into the bottom of the dust cover 4 through the discharge port 17. Then, the motor 18 is started to drive the multiple stirring rods 20 fixedly connected to the outside of the rotating rod 19 to stir the cement. The outside of the rotating rod 19 is also equipped with a spiral blade 22, which can rotate synchronously with the rotating rod 19, thereby preventing cement from clogging the discharge port 17.

[0018] Specifically, the dust suppression assembly includes a water tank 5 and a water pump 6 fixedly connected to the bottom side of the base plate 1 and the top side of the dust cover 4, respectively. An extraction pipe 25 is fixedly installed on one side of the water pump 6, with the other end extending into the water tank 5. A delivery pipe 7 is fixedly connected to the other side of the water pump 6, with the other end of the delivery pipe 7 fixedly connected to and communicating with a diversion box 8. Multiple round holes are opened on the bottom side of the diversion box 8, and hemp ropes 9 are fixedly connected to each of the round holes. A water collection tray 10 is fixedly connected to one side of the dust cover 4, with the other ends of the multiple hemp ropes 9 fixedly connected to the inner wall of the bottom side of the water collection tray 10. Circulation pipes 11 are fixedly connected to both sides of the water collection tray 10, and both circulation pipes 11 are connected to the water collection tray 10. The other ends of the two circulation pipes 11 extend into the water tank 5. A cutter 30 is fixedly connected to the bottom of the water collection tray 10. A water pump 6 is installed. When the bagged cement enters the dust cover 4, the water pump 6 drives the extraction pipe 25 to extract water from the water tank 5. The water is then transported to the diversion box 8 through the delivery pipe 7. Because multiple hemp ropes 9 are fixedly connected to the bottom of the diversion box 8, the water will flow along the hemp ropes 9, thereby effectively preventing dust from spreading when the bagged cement is broken. The water flowing on the hemp ropes 9 will accumulate in the water collection tray 10, and then flow back into the water tank 5 from the circulation pipes 11 fixedly installed on both sides of the water collection tray 10, thereby realizing the recycling of water resources.

[0019] Specifically, the pushing component includes a side plate 27 fixedly installed on one side of the base plate 1, an electric push rod 28 fixedly installed on one side of the side plate 27, the output end of the electric push rod 28 passing through the side plate 27 and fixedly connected to a push plate 29, the push plate 29 facing the conveyor belt 3. By setting the push plate 29, the electric push rod 28 can be started to push the bagged cement onto the conveyor belt 3 through the push plate 29. Since a cutter 30 is set above the conveyor belt 3, the bagged cement will be cut by the cutter 30 during the movement, so that the cement is transported along the conveyor belt 3 into the funnel 16. This process does not require manual handling and cutting.

[0020] Specifically, a common connecting pipe 23 is fixedly connected between the water tank 5 and the dust cover 4. The two ends of the connecting pipe 23 are connected to the water tank 5 and the dust cover 4 respectively. A flow valve 24 is installed on the outside of the connecting pipe 23. A high-pressure pump 26 is fixedly installed on one side of the dust cover 4. The high-pressure pump 26 is located below the lever 13. Through the connecting pipe 23, when water needs to be added to the dust cover 4 to mix with cement, the flow valve 24 is activated, so that the water in the water tank 5 is transported to the dust cover 4 through the connecting pipe 23, thereby completing the cement mixing process. After the mixing is completed, the cement can be pumped away for use by the high-pressure pump 26.

[0021] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0022] In use: After placing the bagged cement on the side plate 27, start the electric push rod 28. Its output end will drive the push plate 29 to move smoothly, accurately pushing the bagged cement onto the conveyor belt 3. Since a cutter 30 is fixedly installed directly above the conveyor belt 3, when the bagged cement is conveyed forward with the conveyor belt 3, the top of the bag will be cut open by the cutter 30, and the cement will flow out from the opening, sliding down the inclined angle of the conveyor belt 3 into the funnel 16. And through the dust cover 4, when the bagged cement enters the dust cover 4, the water pump 6 starts simultaneously, drawing clean water from the water tank 5 through the extraction pipe 25, and then conveying the clean water to the top of the dust cover 4 through the conveying pipe 7. Inside the diversion box 8, multiple hemp ropes 9 are evenly fixedly connected to the bottom side of the diversion box 8. Clean water will slowly seep along the hemp ropes 9 and flow downwards, forming a water curtain barrier inside the dust cover 4, effectively absorbing the scattered cement dust and preventing it from leaking out and polluting the environment. At the same time, a water collection tray 10 is installed on one side of the dust cover 4. Water that has not been completely evaporated on the hemp ropes 9 will drip into the water collection tray 10, and then flow back to the water tank 5 through the circulation pipes 11 fixedly installed on both sides of the water collection tray 10, realizing the recycling of water resources and reducing water costs. By setting up a fixing frame 14, different numbers of counterweights 15 can be placed on the fixing frame 14, and the operator can adjust the weight of the cement according to the required weight. Select the appropriate counterweight. In the initial state, the weight of the counterweight 15 causes the right side of the lever 13 to sink and the left end to tilt upward. At this time, the funnel 16 tilts upward with the left end of the lever 13, and the discharge port 17 opened on its bottom inner wall is tightly fitted with the bottom side of the baffle 21. The baffle 21 seals the discharge port 17 to prevent cement from leaking prematurely and affecting the mixing accuracy. As cement is continuously delivered into the funnel 16, its weight gradually increases. When the total weight of the funnel 16 and the cement exceeds the weight of the counterweight 15, the left end of the lever 13 sinks, and the discharge port 17 is released from the baffle 21. The cement then falls from the discharge port 17 into the mixing chamber at the bottom of the dust cover 4. At this time, the motor 18 is started. The rotating rod 19 rotates at high speed, and the multiple mixing rods 20 fixed on the outside of the rotating rod 19 will fully mix the cement falling into the mixing chamber. At the same time, the spiral blades 22 set at the bottom of the rotating rod 19 rotate synchronously, which can push the cement that may accumulate at the discharge port 17 downward to avoid blockage. During the mixing process, the flow valve 24 on the connecting pipe 23 automatically adjusts the opening according to the preset ratio, and delivers the clean water in the water tank 5 to the mixing chamber in proportion, which mixes with the cement to form a slurry. After the slurry is evenly mixed, the high-pressure pump 26 starts, and extracts the proportioned cement slurry through the slurry extraction pipe and delivers it to the grouting system of the high-pressure jet grouting pile for subsequent construction.
