DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Please refer to Figures 1-5The utility model provides an embodiment: a kind of mud scraper convenient to maintain, comprising: sludge pool 1, the inner bottom of sludge pool 1 is provided with the pool bottom 102 with inclination angle, the center position of pool bottom 102 is provided with sludge outlet 103, the top of sludge pool 1 is provided with working bridge 101, the middle position of working bridge 101 is installed with drive assembly 2, drive assembly 2 includes the transmission shaft 203 extending to sludge pool 1, the outer wall of transmission shaft 203 is annularly spaced apart and is provided with multiple assembly components 3, assembly component 3 includes support frame 301, assembly groove 302 is opened on the outer wall of support frame 301, and scraper assembly 4 is installed in assembly groove 302, and scraper assembly 4 includes multiple groups of split assembly combined frame 401, and the lower bottom of assembly combined frame 401 is installed with scraper main body 404, and scraper main body 404 is arranged in 45 ° inclination, the outer wall of both sides of assembly groove 302 is provided with a plurality of first docking holes 305 arranged transversely, the outer wall of assembly combined frame 401 is provided with multiple second docking holes 402, and the first docking hole 305 and the second docking hole 402 are combined and installed by bolt;

[0025] By the setting of scraper assembly 4 and assembly component 3, the scraper main body 404 can be detached from the support frame 301, and multiple split scrapers are installed at each support frame 301, so that the user can replace a certain scraper individually when replacing, which is more convenient and lower in cost than the integral scraper.

[0026] Specifically, the second docking hole 402 of the assembly combined frame 401 is aligned with the first docking hole 305 when being installed in the assembly groove 302 of the support frame 301, and the combined fixing of the two is realized by means of fixed bolts, which is convenient for the user to install and disassemble during subsequent maintenance.

[0027] In addition, the upper top of the assembly combined frame 401 is installed with a lifting handle 406, which can be used by the user to pull upward to remove the scraper after disassembling the bolt, and the user can also use the lifting method to hang the lifting hook on the lifting handle 406 after disassembling the bolt below, and then hoist and remove the scraper from the sludge pool 1, which is convenient for the user to maintain.

[0028] Please refer to Figure 4 The two sides of the assembly groove 302 are provided with displacement sliding grooves 303, and the two sides of the lower surface of the assembly combined frame 401 are installed with displacement sliding blocks 403, and the assembly combined frame 401 slides in the displacement sliding grooves 303 through the displacement sliding blocks 403, and the displacement sliding grooves 303 are provided with a displacement channel 304 for the scraper main body 404 to pass through;

[0029] When the assembly combination frame 401 is assembled into the assembly groove 302, the displacement sliding block 403 at the bottom thereof is embedded into the displacement sliding groove 303, so that the assembly combination frame 401 is movable, and the position of the scraper main body 404 can be moved and switched before being fixed. The structure can adaptively adjust the installation position of the scraper based on different sizes of the scraper, which is convenient for users to use. When moving, the scraper main body 404 extends downward through the displacement channel 304, so that the scraper main body 404 can be displaced together.
