DETAILED DESCRIPTION

[0014] 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.

[0015] like Figure 1 and Figure 2 As shown, an adjustable center-drive scraper includes a center rotating rod 1, a scraper arm 2 is provided at the bottom of the center rotating rod, and a bracket 3 is provided on the center rotating rod. The bracket is arranged above the scraper arm, and a connecting rod 4 is provided between the end of the bracket and the end of the scraper arm. The connection method can be connected by fasteners such as bolts. The scraper arm is provided with a number of evenly spaced scraper blades 7. The end of the scraper arm facing away from the center rotating rod is provided with a groove on the side of the center rotating rod. An extension arm 5 is slidably connected in the groove, and the sliding direction is the same as the length direction of the scraper arm. A second scraper blade 8 is provided on the extension arm, and a fixed rod 6 is provided on the extension arm. A positioning structure is provided between the fixed rod and the connecting rod. The positioning structure includes a threaded rod 9. The threaded rod passes through the fixed rod and the connecting rod and is screwed with four sets of nuts. The four sets of nuts respectively press against the two sides of the fixed rod and the connecting rod. The arrangement of the positioning structure further increases the stability of the extension arm arrangement.

[0016] Furthermore, the scraper blade and the second scraper blade have the same structure, including a connecting portion 12 and a scraping portion 13. The connecting portion is provided with a through-hole 14, through which a scraper arm passes. The scraper arm has threads on the outside, and a plurality of second nuts are mounted on the threads. Two sets of second nuts cooperate to tighten against the two sides of the scraper blade connecting portion. Furthermore, a connecting portion 15 is provided on the front or rear side of the through-hole, extending through the outside of the connecting portion. This facilitates the deployment of the scraper blades.

[0017] Furthermore, the connecting portion is provided with fixing holes 11. Through the fixing holes of the multiple scraper blades and the second scraper blade, a through rod 10 is inserted. Nuts are provided at both ends of the through rod, which are then threaded onto a third nut. This further ensures the structural stability of the scraper blades during operation. The through rod can also pass through the connecting rod and the fixing rod.

[0018] The working principle of the utility model is as follows: multiple sets of nuts are arranged on the scraper arm, then the scraper blade is arranged, the nuts are rotated to achieve positioning, then the connecting rod is arranged, then the extension arm is selected and arranged according to the size of the sedimentation tank, then the relative fixation between the extension arm and the scraper arm is achieved through the positioning piece, then the second scraper blade is arranged, and finally the through rod is arranged to further achieve the overall stable connection arrangement.
