[0012] Compared with the prior art, the present invention provides a concrete feed opening wall cleaning robot, which has the following beneficial effects:

[0013] 1. The concrete discharge port wall cleaning robot guides water into the water pipe through the spring tube, and then uses the nozzle to spray the wall to moisten and rinse the wall. When the spray pipe is above the inside of the discharge chamber, the spring tube shrinks together. When the spray pipe descends, the spring tube stretches to meet the descent of the spray pipe, and the limit rope on the inside of the spring tube is always in a tightened state in the winding box, so that the limit rope is always in a tight state when the spray pipe rises or falls, thereby limiting the spring tube to prevent the spring tube from deflecting when it shrinks.

[0014] 2. The concrete discharge port wall cleaning robot is fixedly connected to the linkage block through the reciprocating motor output end arranged at the bottom of the mounting plate, so that the linkage block can rotate in the fixed clamp ring. During installation, the linkage opening on one side of the linkage block is made flush with the fixed opening on one side of the fixed clamp ring, and then the cleaning component is passed through the linkage opening and the fixed opening and clamped into the linkage block, which is convenient for the replacement and installation of the cleaning component.

[0015] 3. The concrete discharge port wall cleaning robot automatically cleans the wall through an intelligent control system. First, the cleaning scraper is turned close to the wall. Driven by the driving mechanism, the cleaning scraper moves downward to scrape off the sludge blocks on the wall. While scraping off the sludge blocks, the infrared scanner above the cleaning component scans the wall and records the area with sludge traces. Then the driving mechanism is controlled to rise, and the cleaning brush is turned to face the wall. The recorded sludge traces are scrubbed with the cleaning brush to achieve intelligent cleaning of the wall surface of the concrete discharge port.

[0016] 4. The concrete discharge port wall cleaning robot guides the water left after cleaning the wall through the drain tank, and filters the sediment in the sewage through the filter net. When the wall needs to be cleaned, the protective plate is flipped over. Under the action of the limit block, the protective plate is opened and tilted outward. Then the water generated during cleaning falls into the drain tank. The outward-tilted protective plate prevents the sewage from splashing outside the drain tank. When loading concrete, the protective plate is flipped inward. Under the support of the baffle, the protective plate is above the drain tank and tilted outward to prevent concrete from falling into the drain tank.

[0017] 5. The concrete discharge port wall cleaning robot cooperates with the linkage block by the fixed blocks arranged at both ends of the cleaning connecting plate, so that the two ends of the cleaning connecting plate can be installed in the linkage block, and the fixed block and the linkage block are matched to form a truncated cone structure, so that after the fixed block is installed in the linkage block, it can rotate in the fixed clamp ring to realize the replacement of the cleaning scraper and the cleaning brush, thereby achieving the continuity of automatic cleaning without replacing the cleaning tools, saving cleaning time.

[0028] Furthermore, the driving mechanism 3 also includes a driving motor 31, which is arranged at the top of the unloading chamber 1. Two conveyor belts 32 are arranged at the output end of the driving motor 31. A motor cover 33 is arranged outside the driving motor 31. The other ends of the two conveyor belts 32 are respectively connected to transmission screws 34. The driving motor 31 is used to drive the conveyor belts 32 on both sides at the same time, and then the transmission screws 34 are driven to rotate at the same time through the conveyor belts 32.

[0029] Furthermore, the driving block 4 is threadedly connected to the transmission screw 34, so that the driving block 4 can perform linear motion after the transmission screw 34 rotates. A guide frame 35 is arranged around the transmission screw 34, and the guide frame 35 is arranged at both ends of the back wall of the unloading chamber 1. The transmission screw 34 is rotatably connected to the unloading chamber 1. The driving block 4 is threadedly connected to the transmission screw 34. When the transmission screw 34 rotates, it cooperates with the guide frame 35 to convert the rotational motion of the transmission screw 34 into the linear motion of the driving block 4.

[0030] Further, see Figure 5 The driving block 4 also includes a mounting plate 41, a reciprocating motor 42 is arranged inside the mounting plate 41 below, a fixing ring 43 is arranged on the side of the reciprocating motor 42 on the mounting plate 41, a fixing opening 44 is arranged on one side of the fixing ring 43, a linkage block 45 is arranged inside the fixing ring 43, and a linkage opening 46 is arranged on one side of the linkage block 45, the output end of the reciprocating motor 42 is located inside the fixing ring 43 and is fixedly connected to the linkage block 45, and the cleaning component 5, the infrared scanner 6 and the spray are controlled by the mounting plate 41.

During installation, the linkage opening 46 on one side of the linkage block 45 is flush with the fixed opening 44 on one side of the fixed clamp ring 43, and then the cleaning component 5 is passed through the linkage opening 46 and the fixed opening 44, and is clamped into the linkage block 45.

[0031] Furthermore, the cleaning component 5 also includes a fixed card block 54, which is arranged at both ends of the cleaning connecting plate 53. When the fixed card block 54 and the linkage card block 45 are matched, they form a truncated cone structure. The cleaning connecting plate 53 is used to cooperate with the linkage card block 45 through the fixed card blocks 54 arranged at both ends, so that the two ends of the cleaning connecting plate 53 can be installed in the linkage card block 45, and the fixed card block 54 and the linkage card block 45 are matched to form a truncated cone structure, so that after the fixed card block 54 is installed in the linkage card block 45, it can rotate in the fixed clamp ring 43. When cleaning the sludge blocks on the wall, the cleaning scraper 51 is first turned close to the wall. Under the drive of the driving mechanism 3, the cleaning scraper 51 moves downward to scrape off the sludge blocks on the wall, and then the driving mechanism 3 is controlled to rise, and the cleaning brush 52 is turned to face the wall, and the cleaning brush 52 is used to scrub the sludge traces.

[0032] Further, see Figure 3 The spray pipe 7 includes a water pipe 72, a nozzle 73 is arranged on one side below the water pipe 72, and the nozzle 73 is arranged toward the back wall of the unloading chamber 1. Both ends of the water pipe 72 are connected to the connecting block 71, and a spring tube 74 is arranged above the connecting block 71. A limit rope 75 is arranged on one side inside the spring tube 74, and a winding box 76 is arranged above the limit rope 75. The winding box 76 is located at the top of the unloading chamber 1. The spring tube 74 is used to guide water into the water pipe 72, and then the wall is sprayed through the nozzle 73. , to moisten and rinse the wall surface. When the spray pipe 7 is above the inside of the discharge chamber 1, the spring tube 74 contracts together. When the spray pipe 7 descends, the spring tube 74 stretches to meet the descent of the spray pipe 7, and the limiting rope 75 on the inside of the spring tube 74 is always in a tightened state in the winding box 76, so that the limiting rope 75 is always in a tight state when the spray pipe 7 rises or falls, thereby limiting the spring tube 74 to prevent the spring tube 74 from deflecting when it contracts.

[0033] Further, see Figure 6The drain mechanism 8 includes a drain tank 81, a filter assembly includes a filter screen 82, and the filter screen 82 is arranged above the drain tank 81. The protective assembly includes a protective plate 83, and the protective plate 83 is rotatably connected to one side of the drain tank 81. Baffles 84 are arranged on both sides of the protective plate 83. When the protective plate 83 is rotated to the top of the filter screen 82, the baffle 84 is used for supporting. A limit block 85 is arranged below the protective plate 83 in the middle of the drain tank 81. The limit block 85 makes the protective plate 83 in an inclined state after opening, and the drain tank 81 is used to drain the water left by cleaning the wall. The filter screen 82 is used to filter the sediment in the sewage. When the wall needs to be cleaned, the protective plate 83 is flipped over. Under the action of the limit block 85, the protective plate 83 is opened and tilted outward, and then the water generated during cleaning falls into the drain tank 81. The outward tilted protective plate 83 prevents the sewage from splashing outside the drain tank 81. When loading concrete, the protective plate 83 is flipped inward. Under the support of the baffle plate 84, the protective plate 83 is above the drain tank 81 and tilted outward to prevent the concrete from falling into the drain tank 81.

[0034] Working principle: When in use, when concrete is loaded, the automatic cleaning robot is located at the top of the inner cavity of the unloading chamber 1, and uses the spring tube 74 to guide water into the water pipe 72, and then sprays the wall through the nozzle 73. The wall is first soaked through the spray pipe 7 to prevent concrete debris from splashing onto the wall and drying directly during loading. The spring tube 74 is used to guide water into the water pipe 72, and then sprays the wall through the nozzle 73 to moisten and rinse the wall. When the spray pipe 7 is above the inside of the unloading chamber 1, the spring tube 74 shrinks together. When the spray pipe 7 drops, the spring tube 7 4 is stretched to meet the descent of the spray pipe 7, and the limit rope 75 on the inner side of the spring tube 74 is always in a tightened state in the winding box 76, so that the limit rope 75 is always in a tight state when the spray pipe 7 rises or falls, thereby limiting the spring tube 74 to prevent the spring tube 74 from deflecting when it contracts, and then the protective plate 83 is turned inward. Under the support of the baffle 84, the protective plate 83 is above the drain tank 81 and tilted outward to prevent concrete from falling into the drain tank 81 during loading. The transport vehicle drives into the unloading chamber 1, and the unloading bucket 2 is used to load the concrete into the transport vehicle.

[0035] When the loading is completed, the protective plate 83 is flipped first. Under the action of the limit block 85, the protective plate 83 is opened and tilted outward. The intelligent control system controls the driving mechanism 3 to drive the cleaning component 5, the infrared scanner 6 and the spray pipe 7 to clean the wall surface. The driving motor 31 in the driving mechanism 3 drives the conveyor belts 32 on both sides at the same time, and then drives the transmission screw 34 to rotate through the conveyor belt 32. Under the threaded connection between the driving block 4 and the transmission screw 34, when the transmission screw 34 rotates, it cooperates with the guide frame 35 to convert the rotary motion of the transmission screw 34 into the linear motion of the driving block 4.

[0036] The mounting plate 41 is used to mount the cleaning assembly 5, the infrared scanner 6 and the spray pipe 7, so that the driving block can drive the cleaning assembly 5, the infrared scanner 6 and the spray pipe 7 to clean the wall surface. The output end of the reciprocating motor 42 arranged at the bottom of the mounting plate 41 is fixedly connected with the linkage block 45, so that the linkage block 45 can rotate in the fixed clamp ring 43. During installation, the linkage opening 46 on one side of the linkage block 45 is flush with the fixed opening 44 on one side of the fixed clamp ring 43, and then the cleaning assembly 5 is passed through the linkage opening 46 and the fixed opening 44, and is clamped into the linkage block 45;

[0037] By using the intelligent control system, the wall surface is automatically cleaned. The cleaning connecting plate 53 in the cleaning component 5 cooperates with the linkage block 45 through the fixed blocks 54 arranged at both ends, so that the two ends of the cleaning connecting plate 53 can be installed in the linkage block 45, and the fixed block 54 and the linkage block 45 are matched to form a truncated cone structure, so that after the fixed block 54 is installed in the linkage block 45, it can rotate in the fixed clamp ring 43. When cleaning the sludge blocks on the wall surface, the cleaning scraper 51 is first turned close to the wall surface, and driven by the driving mechanism 3, the cleaning scraper 51 moves downward to scrape off the sludge blocks on the wall surface. While the sludge blocks are being scraped off, the infrared scanner 6 above the cleaning component 5 scans the wall surface and records the area with sludge traces, and then controls the driving mechanism 3 to rise, turns the cleaning brush 52 to face the wall surface, and uses the cleaning brush 52 to scrub the recorded sludge traces.

[0038] During cleaning, the sludge blocks scraped off by the cleaning scraper 51 and the sewage generated by cleaning fall directly into the drain tank 81. The drain tank 81 drains the water left by cleaning the wall and filters the silt in the sewage through the filter net 82. Since the protective plate 83 is flipped on one side of the drain tank 81 and under the action of the limit block 85, the protective plate 83 is in an outwardly inclined state after opening. The water generated during cleaning falls into the drain tank 81, and the outwardly inclined protective plate 83 prevents the sewage from splashing outside the drain tank 81.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
