[0024] The top of the rotating disk 6 is rotatably connected to a connecting rod 7, and the connecting rod 7 can be moved by the rotation of the rotating disk 6. The other end of the connecting rod 7 is rotatably connected to a rack plate 8, and the movement of the connecting rod 7 can push and pull the rack plate 8 to move. The top left end of the support plate 4 is rotatably connected to a gear 9, and the rack plate 8 and the gear 9 are meshingly connected. The gear 9 can be rotated by the rotation of the rack plate 8. The bottom of the gear 9 is fixedly connected to a transmission rod 10, and the rotation of the gear 9 causes the transmission rod 10 to rotate. The bottom of the transmission rod 10 is detachably connected to a fixed plate 11, and the bottom of the fixed plate 11 is fixedly connected to a plurality of rust removal brushes 12, and the rust removal brushes 12 are used to clean the steel bars. The top right end of the bottom plate 1 is fixedly connected to an infusion assembly.

[0025] The infusion assembly includes a box body 13, the bottom of which is fixedly connected to the top right end of the base plate 1, and a water pump 14 is fixedly connected to the bottom of the left end of the box body 13. The rust removal liquid inside the box body 13 can be sucked through the water pump 14. The bottom of the water pump 14 is fixedly connected to the top of the base plate 1, and the output end of the water pump 14 is fixedly connected to a water pipe 15. The other end of the water pipe 15 is fixedly connected to the outside of the transmission rod 10. When the water pump 14 is started, the rust removal liquid inside the box body 13 can enter the water pipe 15 and then enter the transmission rod 10 to be transmitted downward in sequence. Both sides of the transmission rod 10 are slidably connected with disassembly assemblies.

[0026] The disassembly assembly includes two control rods 16, which are respectively slidably connected to the outer sides of the transmission rod 10. The disassembly of the fixed plate 11 can be controlled by the control rods 16. The adjacent sides of the two control rods 16 are fixedly connected with a push plate 17, and the push plate 17 can be moved when the control rods 16 are moved. The adjacent sides of the two push plates 17 are rotatably connected with a rotating rod 18, and the rotating rod 18 can be rotated when the push plate 17 is moved. The outer part of the rotating rod 18 is engaged with the inner wall of the fixed plate 11, so that the fixed plate 11 is fixed.

The four corners of the base plate 1 are provided with moving wheels, which are convenient for moving on the construction site.

[0028] Working principle: First, when in use, the hydraulic cylinder 3 is started. At this time, the support plate 4 can be moved with the start of the hydraulic cylinder 3, so that the fixed plate 11 can be pushed by the transmission rod 10 under the movement of the support plate 4 to make the rust removal brush 12 descend. At this time, the rust removal brush 12 contacts the outer surface of the steel bar for cleaning. When cleaning, the motor 5 and the water pump 14 need to be started. The start of the motor 5 can drive the rotating disk 6 to rotate, and the rotation of the rotating disk 6 can rotate the connecting rod 7, and the connecting rod 7 can make the rack plate 8 reciprocate when rotating. The rack plate 8 is moved, and the gear 9 can be rotated by the movement of the rack plate 8. At this time, the transmission rod 10 can be rotated under the rotation of the gear 9. The rotation of the transmission rod 10 makes the fixed plate 11 reciprocate with the rust removal brush 12. The steel bars are cleaned by the rotation of the rust removal brush 12, thereby achieving the rust removal effect. By starting the water pump 14, the water pump 14 draws the rust removal liquid inside the box body 13 into the water pipe 15, and then enters the slot 19 through the water pipe 15. The rust removal liquid enters the rust removal brush 12 through the slot 19, thereby being able to more effectively clean the steel bars.

[0029] When the rust removing brush 12 is used for a long time, it will cause wear and tear and needs to be replaced. At this time, by pressing the two control rods 16, the push plate 17 can be moved when the control rod 16 is pressed. The movement of the push plate 17 can drive the rotating rod 18 to rotate. When the rotating rod 18 rotates, the engagement with the inner wall of the fixed plate 11 is cancelled, thereby achieving the effect of disassembling the rust removing brush 12 and replacing the rust removing brush 12 to ensure the effect of rust removal on the steel bars.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
