Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a material feeding device for a seepage-proof wall. Background Technology

[0002] A cutoff wall is a continuous wall built in a loose permeable layer or an earth-rock dam to prevent seepage. During the construction of the cutoff wall, concrete pouring is required. A pouring hopper is used to pour the concrete into the hopper, and the hopper is then lifted by hoisting equipment to the pouring position. The concrete in the hopper is then transported to the pouring position through the discharge pipe, thus forming the cutoff wall.

[0003] In the prior art, application number 202320119885.1 proposes a feeding device for concrete anti-seepage walls, in which a drive motor can drive the feeding propeller to rotate during feeding, which can improve the uniformity of feeding and avoid clogging of the feeding nozzle during feeding.

[0004] However, during the use of the above-mentioned patent, due to the viscosity of concrete, some concrete will adhere to the inner wall of the pouring hopper when it discharges concrete from its interior, which will cause errors in the concrete discharge from the pouring hopper. Moreover, the concrete solidifies in the pouring hopper, which will reduce the volume of the pouring hopper. Based on the above problems, this application proposes a discharge device for a seepage-proof wall. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a material feeding device for a seepage-proof wall, which solves the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A material feeding device for an anti-seepage wall includes a casting hopper, a discharge pipe fixedly installed at the bottom of the casting hopper, an installation plate fixedly installed inside the casting hopper, a rotary scraper assembly installed on the surface of the installation plate, a spiral feeding assembly installed at the discharge end of the discharge pipe, a fixing plate fixedly installed on the surface of the casting hopper, and a lifting lug fixedly installed on the top of the fixing plate.

[0007] Preferably, the rotary scraper assembly includes a mounting bracket fixedly mounted on the top of a mounting plate. A drive motor is fixedly mounted on the top of the mounting bracket.

The spring is fixedly connected to the hollow sleeve. The connecting rod is slidably connected to the hollow sleeve. A connecting plate is fixedly mounted on the end of the connecting rod located outside the sliding plate. A scraper is fixedly mounted on the side of the connecting plate away from the connecting rod. The scraper is in contact with the pouring hopper.

[0008] Preferably, a rotating rod is fixedly provided at the bottom of the rotating shaft, and a dispersing rod is fixedly provided on the surface of the rotating rod. Both the rotating rod and the dispersing rod are located inside the discharge pipe, and the dispersing rod does not contact the discharge pipe.

[0009] Preferably, the spiral feeding assembly includes a conveying bin fixedly installed at the discharge end of the discharge pipe, a fixed bracket fixedly installed at the rear side of the conveying bin, a rotary motor fixedly installed at the rear side of the fixed bracket, a coupling fixedly installed at the output end of the rotary motor, a feeding auger installed at the output end of the rotary motor through the coupling, the feeding auger being located inside the conveying bin, and a discharge pipe fixedly installed at the bottom of the conveying bin.

[0010] Preferably, there are four fixing plates and four lifting lugs, and the four fixing plates and four lifting lugs are arranged in a circular array.

[0011] Preferably, the scraper consists of a vertical scraper section and an inclined scraper section, wherein the vertical scraper section contacts the vertical inner wall of the casting hopper, and the inclined scraper section contacts the inclined inner wall of the casting hopper.

[0012] Preferably, the top of the conveying bin is provided with a feed inlet for feeding materials, and the bottom of the conveying bin is provided with a discharge outlet for discharging materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the material feeding device of the seepage prevention wall scrapes off the concrete adhering to the inner wall of the pouring hopper by rotating the scraper assembly, so that the concrete adhering to the pouring hopper can also be discharged. Moreover, when the scraper assembly rotates, it can drive the rotating rod to rotate, so that the rotating rod drives the dispersing rod to disperse the concrete accumulated in the discharge pipe, thus avoiding the situation where some concrete adheres to the inner wall of the pouring hopper, causing errors in the concrete feeding in the pouring hopper. It also avoids the situation where the concrete solidifies in the pouring hopper, resulting in a reduction in the volume of the pouring hopper. Attached Figure Description

[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] Example: Refer to Figure 1-4A material feeding device for a seepage-proof wall includes a casting hopper 1, a discharge pipe 2 fixedly installed at the bottom of the casting hopper 1, an installation plate 3 fixedly installed inside the casting hopper 1, a rotary scraper assembly installed on the surface of the installation plate 3, a spiral feeding assembly installed at the discharge end of the discharge pipe 2, a fixing plate 19 fixedly installed on the surface of the casting hopper 1, and a lifting lug 20 fixedly installed on the top of the fixing plate 19. There are four fixing plates 19 and four lifting lugs 20, and the four fixing plates 19 and four lifting lugs 20 are arranged in a circular array. The fixed plate 19 and four lifting lugs 20 provide more stress points for the pouring hopper 1 during hoisting, making it more stable. The rotary scraper assembly includes a mounting bracket 4 fixedly installed on the top of the mounting plate 3. A drive motor 5 is fixedly installed on the top of the mounting bracket 4. A coupling is fixedly installed at the output end of the drive motor 5. A rotating shaft 6 is installed at the output end of the drive motor 5 through the coupling. A mounting block 7 is fixedly installed on the surface of the rotating shaft 6. A hollow sleeve 8 is fixedly installed on the side of the mounting block 7. A sliding plate 9 is internally mounted on the hollow sleeve 8. A spring 10 is fixedly mounted on one side of the sliding plate 9, and a connecting rod 11 is fixedly mounted on the other side of the sliding plate 9. The spring 10 is fixedly connected to the hollow sleeve 8, and the connecting rod 11 is slidably connected to the hollow sleeve 8. A connecting plate 12 is fixedly mounted on the end of the connecting rod 11 located outside the sliding plate 9. A scraper 13 is fixedly mounted on the side of the connecting plate 12 away from the connecting rod 11. The scraper 13 consists of a vertical scraper section and an inclined scraper section. The vertical scraper section is connected to the casting hopper 1. The vertical inner wall of the hopper 1 is in contact with the inclined section of the scraper, which in turn contacts the inclined inner wall of the hopper 1. This allows for comprehensive scraping of the inner wall of the hopper 1, avoiding dead corners during the scraping process. The scraper 13 contacts the hopper 1 and drives the coupling through the drive motor 5 to rotate the rotating shaft 6. The rotating shaft 6 drives the connecting rod 11 to rotate through the mounting block 7. The connecting rod 11 drives the scraper 13 to make a circular motion through the connecting plate 12, so that the scraper 13 scrapes off the concrete adhering to the inner wall of the hopper 1.

[0018] Specifically, a rotating rod 21 is fixedly installed at the bottom of the rotating shaft 6, and a dispersing rod 22 is fixedly installed on the surface of the rotating rod 21. Both the rotating rod 21 and the dispersing rod 22 are located inside the discharge pipe 2, and the dispersing rod 22 does not contact the discharge pipe 2. During the rotation of the rotating shaft 6, the rotating shaft 6 will drive the rotating rod 21 to rotate, and the rotating rod 21 will drive the dispersing rod 22 to rotate, so that the dispersing rod 22 will disperse the concrete blocked in the discharge pipe 2, thus preventing the discharge pipe 2 from being blocked and causing the concrete to be unable to be discharged.

[0019] Specifically, the spiral feeding assembly includes a conveying chamber 14 fixedly installed at the discharge end of the discharge pipe 2. The top of the conveying chamber 14 has a feed inlet for feeding, and the bottom of the conveying chamber 14 has a discharge outlet for discharging. A fixed bracket 15 is fixedly installed at the rear of the conveying chamber 14, and a rotary motor 16 is fixedly installed at the rear of the fixed bracket 15. A coupling is fixedly installed at the output end of the rotary motor 16, and a feeding auger 17 is installed at the output end of the rotary motor 16 via the coupling. The feeding auger 17 is located inside the conveying chamber 14, and a discharge pipe 18 is fixedly installed at the bottom of the conveying chamber 14 to discharge the required material. Concrete is placed into the pouring hopper 1. External hoisting equipment lifts the pouring hopper 1 using the fixed plate 19 and lifting lugs 20. After the pouring hopper 1 is lifted to the discharge position, the rotating motor 16 drives the coupling to rotate the feeding auger 17, causing the feeding auger 17 to move the incoming concrete. When the concrete moves to the bottom discharge port of the conveying silo 14, it enters the discharge pipe 18 through the discharge port and enters the casting position through the discharge pipe 18. Meanwhile, the concrete in the pouring hopper 1 continuously enters the conveying silo 14 through the discharge pipe 2 and the inlet, thus completing the material feeding process of the anti-seepage wall.

[0020] In use: The drive motor 5 drives the coupling to rotate the rotating shaft 6, which in turn drives the mounting block 7 to rotate. This causes the mounting block 7 to rotate the connecting rod 11, which in turn drives the connecting plate 12 to rotate. The connecting plate 12 then drives the scraper 13 to rotate, causing the scraper 13 to scrape off the concrete adhering to the inner wall of the pouring hopper 1. Since the spring 10 is in a compressed state, it provides a thrust to the connecting rod 11 through the sliding plate 9. This, in turn, provides a thrust to the scraper 13 through the connecting plate 12, ensuring that the scraper 13 is in complete contact with the inner wall of the pouring hopper 1.
