[0029] Specifically, the lubrication assembly 78 includes an L-shaped bracket 781, a liquid storage tank 782, an infusion pump 783, an infusion tube 784, a first lubrication tube 785, and a second lubrication tube 786.

[0040] Example 2

[0041] The difference between this embodiment and embodiment 1 is that, specifically, the connecting component 8 includes a connecting seat 81, a connecting block 82, a positioning block 83, a fixing seat 84, a fixing rod 85, a pressing block 86, and a fixing spring 87. The two ends of the scraper drive component 4 are symmetrically and fixedly connected to the connecting seat 81. A connecting block 82 is tightly inserted into one side of the connecting seat 81. Positioning blocks 83 are fixedly connected to both sides of the connecting block 82, and the positioning blocks 83 and the connecting seat 81 are tightly inserted. A fixing seat 84 is installed at one end of the connecting seat 81. A fixing rod 85 is slidably connected to the middle of the fixing seat 84, and the fixing rod 85 and the connecting seat 81 are slidably connected.

A fixing spring 87 is fixedly connected above the pressing block 86, and the upper part of the fixing spring 87 is fixedly connected to the fixing seat 84.

[0042] By adopting the above technical solution, by pulling the fixing rod 85, the fixing rod 85 drives the squeezing block 86 to move and compress the fixing spring 87, so that the fixing rod 85 disengages from the fixing hole above the connecting block 82. Then, by separating the connecting block 82 and the positioning block 83 from the connecting seat 81, the first scraper 5 or the second scraper 6 fixed below the connecting block 82 can be removed for cleaning or replacement.

[0043] Specifically, mounting blocks 88 are fixedly connected to both sides of the fixed base 84, and mounting screws 89 are installed in the middle of the mounting blocks 88. The mounting screws 89 are threadedly connected to the connecting base 81.

[0044] By adopting the above technical solution, the mounting block 88 and mounting screw 89 cooperate to facilitate the assembly between the fixing seat 84 and the connecting seat 81.

[0045] Specifically, a fixing hole is provided at one end of the connecting block 82 to be tightly inserted into the fixing rod 85.

[0046] By adopting the above technical solution, the fixing hole facilitates the insertion of the fixing rod 85 to fix the connecting block 82.

[0047] In this embodiment, when in use: by pulling the fixing rod 85, the fixing rod 85 drives the pressing block 86 to move and compress the fixing spring 87, so that the fixing rod 85 disengages from the fixing hole above the connecting block 82. Then, by separating the connecting block 82 and the positioning block 83 from the connecting seat 81, the first scraper 5 or the second scraper 6 fixed below the connecting block 82 can be removed for cleaning or replacement. The mounting block 88 and the mounting screw 89 cooperate to facilitate the assembly between the fixing seat 84 and the connecting seat 81, so that the first scraper 5 or the second scraper 6 can be easily disassembled and installed for cleaning or replacement during use.

[0048] The infusion pump 783 in this utility model is a previously disclosed technology, and the selected model is AM3050GYW.

[0049] The structure and operating principle of the wastewater treatment tank 1, support frame 2, lifting frame 3, scraper drive assembly 4, first scraper 5, and second scraper 6 in this utility model have been disclosed in a scraper machine for catering wastewater treatment disclosed in Chinese patent application number 202121824515.5. Its working principle is as follows: the scraper drive assembly 4 includes a guide rod, a first connecting frame, a screw, a second connecting frame, a scraper fixing rod, and a motor. In use, by controlling the scraper drive assembly 4, the first scraper 5, and the second scraper 6 to move below the water surface, when there are many floating impurities that need to be scraped off, the motor simply drives the screw to rotate clockwise. When the screw rotates clockwise, it drives the first and second connecting frames to slide synchronously towards the center position. This allows scraper 5 and scraper 6 to gradually approach each other. During this approach, the protrusion on the left side of the bottom horizontal plate of scraper 6 will embed into the groove on the right side of the bottom horizontal plate of scraper 5, thus connecting scraper 5 and scraper 6 together through an interference fit. At this time, the impurities will be located above the bottom horizontal plates of scraper 5 and scraper 6, and the water will flow out through the narrow grooves on scraper 5 and scraper 6. At the same time, one side of the two sets of side baffles will also fit tightly, thus preventing impurities from leaking out. Then, scraper 5 and scraper 6 are raised back to the highest position, and the connected scraper 5 and scraper 6 are pulled out as a whole and removed, and then the internal impurities can be cleaned.

[0050] The working principle and usage process of this utility model are as follows: In use, the device is installed on the sewage treatment tank 1. Then, the lifting assembly 7 drives the scraper drive assembly 4, scraper 5 (first scraper), and scraper 6 (second scraper) into the water. The scraper drive assembly 4 causes scraper 5 and scraper 6 to gradually approach each other. During this approach, the protrusion on the left side of the bottom horizontal plate of scraper 6 embeds into the groove on the right side of the bottom horizontal plate of scraper 5, thus connecting scraper 5 and scraper 6 together through an interference fit. At this point, impurities are located above the bottom horizontal plates of scraper 5 and scraper 6, and water flows through the first scraper. The narrow grooves on scraper 5 and scraper 6 allow impurities to flow out, and simultaneously, one side of each of the two sets of side baffles will fit tightly together, thus preventing impurities from leaking out. Then, scraper 5 and scraper 6 are raised back to their highest position. Finally, the connected scraper 5 and scraper 6 are removed as a whole via connecting assembly 8, allowing for the cleaning of internal impurities. When using lifting assembly 7, the drive motor 77 is activated, causing gear 2 76 to rotate. Gear 2 76's rotation drives gear 1 75, which in turn rotates the lifting seat 71. The lifting seat 71 then rotates, guiding... Under the action of the slide bar 74, the lifting trapezoidal screw 72 moves up and down, thereby driving the connecting frame 73 to move up and down. This, in turn, causes the lifting frame 3 to drive the scraper drive assembly 4 to rise and fall. By activating the infusion pump 783, the pump extracts lubricating fluid from the storage tank 782 and delivers it through the infusion pipe 784 to lubrication pipes 785 and 786. Lubrication pipe 785 lubricates the lifting trapezoidal screw 72, and lubrication pipe 786 lubricates the meshing joint of gears 75 and 76. This allows the device to easily drive the scraper drive assembly 4 to rise and fall during use. The structure is practical and the connection is seamless. When component 8 is in use, by pulling the fixing rod 85, the fixing rod 85 moves the pressing block 86 to compress the fixing spring 87, so that the fixing rod 85 disengages from the fixing hole above the connecting block 82. Then, by separating the connecting block 82 and the positioning block 83 from the connecting seat 81, the first scraper 5 or the second scraper 6 fixed below the connecting block 82 can be removed for cleaning or replacement. The mounting block 88 and the mounting screw 89 facilitate the assembly between the fixing seat 84 and the connecting seat 81, so that the first scraper 5 or the second scraper 6 can be easily disassembled and installed for cleaning or replacement when the device is in use.
