Description

Technical Field

[0001] This utility model relates to the field of autoclaved aerated concrete block technology, and in particular to a scraping device for autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are porous concrete products made from fly ash, lime, cement, gypsum, slag, and other main raw materials, with the addition of appropriate amounts of foaming agents, regulators, and bubble stabilizers, through processes such as batching, mixing, pouring, static curing, cutting, and high-pressure autoclaving.

[0003] The scraping process of autoclaved aerated concrete (AAC) blocks refers to the process of removing residual waste from the transport vehicle and mold after the AAC block blanks are cut using a special scraping device. After the blanks are cut horizontally, vertically, and milled by the cutting machine, the transport vehicle and mold surfaces are often covered with scraps and debris generated during the cutting process.

[0004] In existing technologies, scrapers are used to clean the scraps and waste adhering to the surface of transport vehicles. However, during the scraper cleaning process, excessive accumulation of waste on the scraper can reduce the cleaning effect. Furthermore, the waste varies in size, and some larger waste is difficult for the scraper to clean completely, resulting in low cleaning quality. Therefore, we urgently need a scraping device for autoclaved aerated concrete blocks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor cleaning effect and waste residue on the scraper in the prior art, and to propose a scraping device for autoclaved aerated concrete blocks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A scraping device for autoclaved aerated concrete blocks includes a bracket and a scraper hinged to the bracket. Hydraulic cylinders are symmetrically mounted on the bracket, and the output ends of the hydraulic cylinders are fixedly mounted to the scraper via extension rods. The device also includes a linear guide rail fixedly mounted on the scraper. Connecting plates are fixedly mounted on both output ends of the linear guide rail, and cleaning components are fixedly mounted on the connecting plates. The cleaning components are in contact with the surface of the scraper. When the two output ends on the linear guide rail are running, the two sets of connecting plates move closer and further apart, rotating a wire brush roller connected to the scraper. The wire brush roller is located on the front side of the scraping edge of the scraper.

[0008] To clean impurities from the scraper, preferably, the cleaning component includes a scraper mounted on a connecting plate, the scraper being in contact with the surface of the scraper, and a horizontal plate being fixedly connected to the connecting plate, with at least two sets of springs on the horizontal plate, the two ends of the springs being connected to the scraper and the horizontal plate respectively.

[0009] To reduce waste material adhering to the scraper, the scraper is further provided with a guide groove, the guide groove having a J-shaped cross-section.

[0010] To further prevent waste from accumulating on the scraper, the guide groove is mainly composed of a vertical section and a hook section, which together form a flow guiding structure.

[0011] To clean the scraper surface, preferably, the cleaning component also includes a cleaning brush fixedly mounted on the connecting plate, which moves linearly across the scraper surface when the connecting plate moves.

[0012] In order to connect with the wire brush roller, preferably, a fixing frame is fixedly installed on the extension rod, and a support rod is hinged on the fixing frame, and the wire brush roller is rotatably connected to the support rod (14).

[0013] Compared with the prior art, the present invention provides a scraping device for autoclaved aerated concrete blocks, which has the following beneficial effects:

[0014] 1. The scraping device for autoclaved aerated concrete blocks, through the design of the cleaning components scraper, horizontal plate, spring and cleaning brush, combined with the drive of the linear guide output end, can reciprocate on the scraper to clean the waste on the scraper surface, effectively improving the cleaning effect of the waste adhering to the scraper and reducing the reduction of cleaning quality due to waste sticking to the scraper surface.

[0015] 2. The scraping device for autoclaved aerated concrete blocks, through the coordinated design of the fixed frame, support rod and wire brush roller, uses the angle adjustment of the support rod to make the wire brush roller fit against the surface of the transport trolley, and uses the force provided by the transport trolley to rotate. The steel wire on the wire brush roller can crush large pieces of waste material, making it easier to shovel up the waste material with a scraper later, further improving the cleaning effect of waste material on the transport trolley.

[0016] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention improves the cleaning effect on waste on transport vehicles and reduces the impact of waste adhering to the scraper, effectively improving cleaning efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-6 A scraping device for autoclaved aerated concrete blocks includes a bracket 1 mounted on an equipment mounting frame or a robotic arm. A scraper 2 is hinged to the lower surface of the bracket 1. Hydraulic cylinders 3 are symmetrically mounted on the bracket 1. The output end of the hydraulic cylinder 3 is fixedly connected to an extension rod 4 on the scraper 2. Here, the output end of the hydraulic cylinder 3 is used to drive the scraper 2 to adjust its angle, so that the scraper 2 can better contact the surface of the transport vehicle and improve the cleaning effect.

[0028] A linear guide rail 5 is fixedly installed on the scraper 2. Here, the linear guide rail 5 is electrically driven and adopts the HIWIN LMC series model, which supports the independent operation of multiple movers. A connecting plate 6 is fixedly installed on the two output ends of the linear guide rail 5. A cleaning component is fixedly installed on the connecting plate 6. The cleaning component is in contact with the surface of the scraper 2. When the two output ends on the linear guide rail 5 are running, the two sets of connecting plates 6 move closer and further away from each other. Here, the design of the cleaning component effectively improves the cleaning effect of the waste adhering to the scraper 2 and reduces the reduction of cleaning quality due to the waste adhering to the surface of the scraper 2.

[0029] The cleaning components include a scraper 8 mounted on a connecting plate 6 and a cleaning brush 12 fixedly mounted on the connecting plate 6. When the connecting plate 6 moves, the cleaning brush 12 moves linearly on the surface of the scraper 2. A horizontal plate 9 is also fixedly connected to the connecting plate 6, and at least two sets of springs 10 are provided on the horizontal plate 9. The two ends of the springs 10 abut against the scraper 8 and the horizontal plate 9, respectively. A guide groove 11 is provided on the scraper 8. The cross-sectional shape of the guide groove 11 is J-shaped. The guide groove 11 is mainly composed of a vertical section and a hook section. The vertical section and the hook section form a flow guiding structure. Here, when the scraper 2 moves linearly along the surface of the transport trolley, the linear guide rail 5 drives the two connecting plates 6 to move in opposite directions, thereby causing the scraper 2 to stop. Dust on scraper 2 enters the guide groove 11 under the scraping of scraper 8, and continuously pushes the waste in the running direction in the closed-loop flow guide space. It should be noted that when scraper 8 moves, it will squeeze spring 10. When scraper 8 moves out of the surface of scraper 2, spring 10 will release its elasticity, causing the dust on scraper 8 to be ejected outward. Then, linear guide 5 drives connecting plate 6 to move in opposite directions. Cleaning brush 12 cleans the waste on scraper 2. This effectively realizes the collection and treatment of waste on scraper 2 during the scraping of waste from the surface of the transport vehicle by scraper 8, further improving the cleaning effect of waste and reducing the waste residue on scraper 2.

[0030] A wire brush roller 7 is rotatably connected to the scraper 2. The wire brush roller 7 is located on the front side of the scraping blade of the scraper 2. A fixing frame 13 is fixedly installed on the extension rod 4, and a support rod 14 is hinged on the fixing frame 13. The wire brush roller 7 is rotatably connected to the support rod 14. Here, the support rod 14 can provide a small angle adjustment. The hinge is connected with damping to prevent the position after angle adjustment from shifting. When the wire brush roller 7 contacts the surface of the transport vehicle, it will rotate and use the wire to crush larger pieces of waste, making it easier to shovel up the waste with the scraper 2 later, further improving the cleaning effect of waste on the transport vehicle.

[0031] In this invention, the bracket 1 is installed on the corresponding connecting frame or at the output end of the robotic arm. When the transport trolley moves below the scraper 2, the output end of the hydraulic cylinder 3 drives the scraper 2 to contact the surface of the transport trolley. As the transport trolley moves, the scraper 2 scrapes away the waste on the surface of the transport trolley. The front wire brush roller 7 crushes the larger waste on the transport trolley, and works in conjunction with the subsequent scraper 2 to clean it. While the scraper 2 is cleaning the waste, as more waste is removed, it accumulates on the scraper 2. The output end of the linear guide rail 5 is activated and drives... The two sets of connecting plates 6 move, and the scraper 8 cleans the accumulated waste along the surface of the scraper 2. The waste will roll continuously in the guide groove 11 until it moves out of the scraper 2. When the scraper 8 is separated from the scraper 2, the spring 10 will cause the scraper 8 to vibrate, shaking off the waste stuck to the scraper 8. At this time, the two sets of connecting plates 6 move closer to each other and work with the cleaning brush 12 to clean the waste again, thereby effectively improving the cleaning effect of the waste on the transport trolley and the waste accumulated on the scraper 2, and further improving the cleaning efficiency.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
