[0022] The adjusting mechanism 7 includes a moving block 71, a threaded rod 72, a gear set 73, a motor 74, a top block 75 and an adjusting groove 76. A groove is formed on the bottom surface inside the mounting base 4, the threaded rod 72 is installed on the side wall of the groove on the bottom surface of the mounting base 4, the moving block 71 is installed on the threaded rod 72 through threads, the motor 74 is installed on the protrusion on the bottom surface of the mounting base 4, the threaded rod 72 and the motor 74 are connected through the gear set 73, the top block 75 is installed on the support rod on the top surface of the moving block 71, an adjusting groove 76 is provided at the bottom of the mounting frame 41, and protrusions matching with the top block 75 are provided on the side wall of the adjusting groove 76.

[0023] The sedimentation tank 1 is used to sediment impurities in the sewage. The driving mechanism 2 provides power for the movement of the transmission chain 3. Several mounting seats 4 are installed on the transmission chain 3 through the connecting mechanism 6. The scraper 5 is installed on the connecting mechanism 6. During the movement of the transmission chain 3, the scraper 5 will be driven to move, thereby realizing the collection of the sedimented impurities. The scraper 5 is installed on the mounting frame 41 through the cooperation of the fixing groove 43 and the fixing rod 44. A through groove matching with the bottom protrusion of the fixing rod 44 is provided on the top surface of the fixing groove 43, ensuring that the user can install the fixing rod 44 into the fixing groove 43. When the user rotates the fixing rod 44, the bottom protrusion of the fixing rod 44 contacts the top wall of the fixing groove 43. At this time, the fixing rod 44 is fixed, ensuring the stability of the scraper 5 after installation. The top protrusion of the fixing rod 44 penetrates the side wall of the scraper 5, facilitating the user to rotate the fixing rod 44. A groove matching with the top protrusion of the fixing rod 44 is provided on the side wall of the scraper 5. The side wall groove of the scraper 5 is used to accommodate the top protrusion of the rotated fixing rod 44. The scraper 5 will be worn during use.

The first spring 42 ensures the stability of the scraper 5 after the position adjustment;

[0024] The motor 74 provides power for the rotation of the threaded rod 72. The power of the motor 74 is transmitted to the threaded rod 72 through the gear set 73. During the rotation of the threaded rod 72, the moving block 71 starts to move under the action of the thread. The moving block 71 is installed in the groove on the inner bottom surface of the mounting seat 4. The top block 75 is located inside the adjustment groove 76, ensuring the stability of the moving block 71 during movement. When the moving block 71 moves, the top block 75 starts to move. A protrusion matching with the top block 75 is provided on the side wall of the adjustment groove 76. The width of the side wall protrusion of the adjustment groove 76 ensures that the top block 75 can completely enter the adjustment groove 76. When the top block 75 moves, the inclined surface of the top block 75 contacts the inclined surface of the side wall protrusion of the adjustment groove 76, realizing the movement of the mounting frame 41. During the movement of the mounting frame 41, the first spring 42 is slowly released. The mounting frame 41 moves outward under the action of the first spring 42, realizing the adjustment of the position of the scraper 5 installed on the mounting frame 41. The width of the adjustment groove 76 ensures that the top block 75 can smoothly enter the adjustment groove 76, ensuring the working effect of the adjusting mechanism 7. After the scraper 5 is installed on the mounting frame 41, move the top block 75. The mounting frame 41 moves into the interior of the mounting seat 4 through the cooperation of the top block 75 and the adjustment groove 76. When the top side wall of the top block 75 contacts the top side wall of the adjustment groove 76, the mounting frame 41 moves to the limit position, and at this time, the installation of the scraper 5 is completed.

[0025] Specifically, planes are provided at both ends of the inclined surface of the side wall protrusion of the adjustment groove 76 that cooperates with the top block 75.

[0026] The two flat ends of the inclined surface of the side wall protrusion of the adjustment groove 76 are used to place the top block 75. The flat surface at the top of the inclined surface of the adjustment groove 76 is used to place the top block 75 when the mounting bracket 41 moves to the limit position. The flat surface at the bottom of the inclined surface of the adjustment groove 76 can prevent the top block 75 from disengaging from the adjustment groove 76, ensuring the stability of the cooperation between the top block 75 and the adjustment groove 76.

[0027] Specifically, the connecting mechanism 6 includes a mounting plate 61, a rotating cylinder 62, a mounting block 63, a first fixing pin 64, a second fixing pin 65 and a second spring 66. The mounting plate 61 is mounted on the side wall of the mounting seat 4. Several mounting blocks 63 are mounted on the transmission chain 3. The rotating cylinder 62 passes through the mounting block 63 and is rotatably mounted on the side wall of the top surface groove of the mounting block 63. The second fixing pin 65 passes through the side wall protrusion of the mounting block 63. The second fixing pin 65 is mounted on the through groove of the side wall protrusion of the mounting block 63 through the second spring 66. Grooves matching with the second fixing pin 65 are symmetrically arranged at the center of the side wall of the rotating cylinder 62. The first fixing pin 64 is mounted on the rotating cylinder 62 through the second spring 66. A through groove matching with the first fixing pin 64 is provided on the bottom protrusion of the mounting plate 61.

[0028] The mounting plate 61 is fixed on the top surface groove of the mounting block 63 through the cooperation of the through groove of the bottom protrusion and the first fixing pin 64, ensuring the stability of the mounting plate 61 after being mounted on the mounting block 63. The cross-sectional shape of the first fixing pin 64 is trapezoidal. When the mounting plate 61 is pressed down, the first fixing pin 64 is pushed into the rotating cylinder 62 by the bottom protrusion of the mounting plate 61, facilitating the user to mount the mounting plate 61 on the mounting block 63. The second spring 66 ensures that the pushed first fixing pin 64 can quickly return to its original position, ensuring the working effect of the first fixing pin 64. The rotating cylinder 62 is rotatably mounted on the mounting block 63. By rotating the mounting block 63, the orientation of the inclined surface of the first fixing pin 64 can be changed, facilitating the user to remove the mounting plate 61 from the mounting block 63. The mounting block 63 is fixed through the cooperation of the second fixing pin 65 and the side wall groove of the mounting block 63, ensuring the stability of the mounting block 63 during the use of the device. The position of the side wall groove of the mounting block 63 ensures that when the mounting block 63 is fixed, the inclined surface of the first fixing pin 64 faces or backs the mounting plate 61. The second fixing pin 65 is mounted on the side wall protrusion of the mounting block 63 through the second spring 66. The moved second fixing pin 65 can quickly return to its original position under the second spring 66, ensuring the working effect of the second fixing pin 65. The second fixing pin 65 passes through the side wall protrusion of the mounting block 63, facilitating the user to release the cooperation between the second fixing pin 65 and the side wall groove of the first fixing pin 64.

[0029] Specifically, the cross-sectional shape of the through groove of the bottom protrusion of the mounting plate 61 is circular.

[0030] The shape of the through groove protruding from the bottom of the mounting plate 61 ensures that the mounting block 63 will not be obstructed during rotation, facilitating the user to remove the mounting plate 61 from the mounting block 63.

[0031] Specifically, two sections of scales are provided on the side wall of the scraper 5. After the scraper 5 is installed on the mounting seat 4, the top of the lower scale is on the same horizontal plane as the top surface of the mounting seat 4, and the top of the upper scale is on the same horizontal plane as the top surface of the scraper 5.

[0032] The top of the upper scale is on the same horizontal plane as the top surface of the scraper 5. When the scraper 5 wears, the top number of the upper scale changes. When the position of the scraper 5 is adjusted by the adjusting mechanism 7, the number where the lower scale overlaps with the top surface of the mounting frame 41 changes, enabling the user to accurately adjust the position of the scraper 5 and ensuring the working effect of the scraper 5.

[0033] Specifically, the side wall of the scraper 5 where the fixing rod 44 is installed faces away from the moving direction of the driving mechanism 2, and the fixing rod 44 is installed at both ends of the scraper 5.

[0034] The installation position of the fixing rod 44 can prevent impurities from accumulating in the side wall groove of the scraper 5. The fixing rods 44 installed at both ends of the scraper 5 ensure the stability of the installation of the scraper 5 and at the same time facilitate the user to release the cooperation between the fixing rod 44 and the fixing groove 43, improving the efficiency of the user in replacing the scraper 5.

[0035] Specifically, several support rods are provided on the bottom surface of the mounting frame 41, and grooves matching the support rods of the mounting frame 41 are provided on the mounting seat 4. The position where the first spring 42 is installed is outside the support rods on the bottom surface of the mounting frame 41.

[0036] The cooperation between the support rods of the mounting frame 41 and the grooves of the mounting seat 4 ensures the stability of the mounting frame 41 during movement. The installation position of the first spring 42 ensures the stability of the first spring 42 during the compression process, preventing the connection between the first spring 42 and the mounting frame 41 and the mounting seat 4 from failing due to the deviation of the first spring 42 during the compression process, and ensuring the working effect of the first spring 42.

[0037] Working principle and usage process of the utility model: Install the scraping plate 5 on the mounting frame 41. As the scraping plate 5 moves, the fixing rod 44 enters the fixing groove 43. Rotate the fixing rod 44, and the scraping plate 5 is fixed on the mounting frame 41 through the cooperation of the fixing groove 43 and the fixing rod 44. Start the motor 74. The threaded rod 72 is driven by the motor 74 to rotate under the action of the gear set 73. When the threaded rod 72 rotates, the moving block 71 moves. The moving moving block 71 drives the top block 75 to move. When the top block 75 moves, the mounting frame 41 moves into the interior of the mounting seat 4 through the cooperation of the top block 75 and the side wall protrusion of the adjustment groove 76. When the top block 75 moves to the limit position, turn off the motor 74. Install the mounting plate 61 on the mounting block 63. As the mounting plate 61 moves, the first fixing pin 64 is pushed into the rotating cylinder 62. After the mounting plate 61 completely enters the mounting block 63, the first fixing pin 64 returns to its original position under the action of the second spring 66. When disassembling the mounting seat 4, pull out the second fixing pin 65 and rotate the rotating cylinder 62. When the inclined surface of the first fixing pin 64 faces away from the mounting plate 61, release the second fixing pin 65. The second fixing pin 65 returns to its original position under the action of the second spring 66. The mounting block 63 is fixed through the cooperation of the side wall groove and the second fixing pin 65. Move the mounting seat 4 upward, and the first fixing pin 64 is pushed into the rotating cylinder 62 by the moving mounting plate 61, completing the disassembly of the mounting seat 4. When adjusting the position of the scraping plate 5, reverse-start the motor 74, and the top block 75 starts to move. The mounting frame 41 moves outward of the mounting seat 4 under the action of the first spring 42, realizing the adjustment of the position of the scraping plate 5.
