[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 In the embodiment of the present invention, an adjustable overflow weir of a flotation machine includes a flotation machine housing 1, an overflow weir trough 2 is provided above one end of the flotation machine housing 1, a connecting fixing plate 3 is fixedly connected to the middle of one side of the overflow weir trough 2, an adjusting chute 5 is provided on the front side of the outer surface of one end of the connecting fixing plate 3, a limiting chute 11 is provided at the upper and lower ends of the adjusting chute 5, a connecting positioning plate 12 is slidably connected to the front side of the adjusting chute 5, one end of the connecting positioning plate 12 is rotatably connected to the positioning plate 13, a positioning nut 15 is provided on the top of one end of the positioning plate 13, one end of the positioning plate 13 is fixedly connected to the middle of one end of the overflow plate 6, a contraction plate 17 is slidably connected to the lower inner side of the overflow plate 6, a docking angle rod 18 is rotatably connected to the lower part of the contraction plate 17, and a first rocking hand 14 is fixedly connected to the middle of the front side of the connecting positioning plate 12.

[0023] In this embodiment, when adjusting the angle and position of the overflow plate 6, the first handle 14 is first pushed toward one end to drive the connection positioning plate 12 fixedly connected to one side of the first handle 14 to slide steadily toward the front side of the connection fixing plate 3 by a specified distance under the guidance of the limiting slide groove 11. During the sliding process, the connection positioning plate 12 drives the positioning plate 13 connected to the middle rotation and the overflow plate 6 fixedly connected to one end of the positioning plate 13 to slide toward the front side of the connection fixing plate 3 by a specified distance, so that the front surface above the overflow plate 6 contacts the upper part of the front side of the flotation housing 1 after adjustment, and then the positioning plate 13 is rotated. After the positioning plate 13 drives the overflow plate 6 to rotate to one side by a certain angle, the positioning nut 15 is rotated so that one end of the positioning nut 15 is locked. Go to the connecting positioning plate 12 and fix the adjusted angle of the overflow plate 6. At this time, pull down the contraction plate 17, and the contraction plate 17 drives the docking angle rod 18 connected to the bottom rotation to move toward the inner wall of the bottom inside the overflow weir groove 2. When the bottom of the docking angle rod 18 contacts the bottom of the overflow weir groove 2, the bottom of the overflow weir groove 2 will push the docking angle rod 18 to rotate a certain angle, so that the outer surface of the bottom of the docking angle rod 18 fits into the surface of the bottom of the overflow weir groove 2, and then fix the adjusted position of the contraction plate 17 to the overflow plate 6 through the nut. At this time, the liquid inside the flotation machine will enter the overflow weir groove 2 along the tilt angle of the overflow plate 6, which makes it easy to adjust the tilt angle of the overflow weir groove 2, thereby adjusting the overflow speed of the liquid.

[0024] Please refer to Figure 1 、 Figure 2 and Figure 4 A first fixing nut 7 is provided in the middle of the rear side of one end of the connecting fixing plate 3, and a second suction cup is rotatably provided at one end of the first fixing nut 7. The rear side of the bottom of the overflow weir trough 2 is fixedly connected to the supporting angle plate 4, and a second fixing nut 8 is provided on the front side below the supporting angle plate 4. The rear side of the second fixing nut 8 is rotatably connected to the first positioning suction cup 16, and a group of fixed support rods 21 are provided in the middle of the bottom end of the overflow weir trough 2. The top of the fixed support rod 21 is fixedly connected to the bottom of the overflow weir trough 2, and the inner side of the fixed support rod 21 is slidably connected to the supporting support rod 19. The bottom of the supporting support rod 19 is clamped with a locking arc block 20. One end of the front side of the inside of the overflow weir trough 2 is slidably connected to the cleaning scraper 9, and one end of the cleaning scraper 9 is detachably connected to the adjustable scraper 10 through a nut.

[0025] In this embodiment: during installation, the supporting angle plate 4 is stuck into the V-shaped groove opened in the middle of the front side of the flotation housing 1, so that the outer surface of the supporting angle plate 4 contacts the inner surface of the V-shaped groove, and the second suction cup provided at one end of the synchronously connected fixing plate 3 will slide to the specified position in accordance with the outer surface of the flotation housing 1. At this time, the first fixing nut 7 is rotated to drive the second suction cup connected to one end of the first fixing nut 7 to move toward the outer surface of the flotation housing 1. The suction force generated by the push of the first fixing nut will be adsorbed on the outer surface of the flotation housing 1 to preliminarily fix the overflow weir trough 2. Then, the second fixing nut 8 is rotated to drive the first positioning suction cup 16 to be adsorbed to the specified position on the outer surface of the V-shaped groove to fix the overflow weir trough 2 for the second time. At this time, the length of the support rod 19 that needs to be extended and retracted is determined according to the distance between the conveying pipe provided in the middle of the lower front side of the flotation housing 1 and the support rod 19. At the same time, the cleaning scraper 9 will drive the adjustable scraper 10 connected at one end to slide from one end of the bottom of the overflow weir trough 2 to the other end of the bottom of the overflow weir trough 2 to scrape and clean the dirt connected to the bottom of the overflow weir trough 2.
