[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] As Figures 1-7 shown, a steel bar rust removal device includes a workbench 1, a cover body 2 is arranged on the upper surface of the workbench 1, a pair of through holes are opened on the cover body 2, a rotary drum 3 is rotatably arranged in the pair of through holes, a plurality of movable slots 3-1 are opened at a position close to the inner side of the rotary drum 3, a plurality of chip discharge slots 3-2 which are staggered with the positions of the movable slots 3-1 are opened on the rotary drum 3, a plurality of telescopic rods 5 are arranged in each movable slot 3-1, a movable rod 4 is connected to the plurality of telescopic rods 5 located in each movable slot 3-1, a spring 6 is sleeved on each telescopic rod 5, an insert slot 4-1 is opened on each movable rod 4, an insert bar 7 is inserted into each insert slot 4-1, the lengths of the movable slot 3-1, the movable rod 4 and the insert bar 7 are the same, a brush bar 8 is arranged on each insert bar 7, an internal thread sleeve 10 is arranged on one side of the rotary drum 3, a sealing cover 11 for limiting the insert bar 7 is threadedly connected to the internal thread sleeve 10, a through slot 11-1 is opened on the sealing cover 11, and a driving component for driving the rotary drum 3 to rotate is arranged on the cover body 2; the driving component includes a motor 12, a gear 13 and an external gear ring 14, the motor 12 is arranged on the cover body 2 and the output end penetrates through the side wall of the cover body 2, the gear 13 is arranged on the output shaft of the motor 12, the external gear ring 14 is arranged on the rotary drum 3, and the gear 13 is meshed with the external gear ring 14; a pair of bearings 9 are arranged between the rotary drum 3 and the cover body 2; a chip discharge port 1-1 is opened on the workbench 1 below the cover body 2.

[0023] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, which are as follows:

[0024] In the present invention, the motor 12 is connected to an external electric control system through a wire. The above devices and connection methods are prior arts and will not be elaborated here.

[0025] According to the appended drawings of the specification Figures 1-7 It can be seen that the movable rod 4 of the present utility model is slidably arranged in the movable groove 3-1. Each telescopic rod 5 is arranged between the movable rod 4 and the rotating cylinder 3. The multiple telescopic rods 5 limit the movement of the movable rod 4. Each spring 6 is sleeved on the telescopic rod 5 and one end is connected to the movable rod 4, and the other end is connected to the rotating cylinder 3. When in use, the rotating cylinder 3 is driven to rotate by the driving assembly. The rotating cylinder 3 drives the multiple telescopic rods 5 in the multiple movable grooves 3-1 to rotate. The multiple telescopic rods 5 drive the multiple springs 6 and the movable rod 4 to rotate. Each movable rod 4 drives the inserting strip 7 to rotate, and the inserting strip 7 drives the brush strip 8 to rotate. Personnel manually or through the feeding device extend the steel bar into the rotating cylinder 3. When the steel bar contacts the brush strip 8, the brush strip 8 will drive the inserting strip 7 to move away from the steel bar, thereby driving the movable rod 4 to move and compressing the spring 6. The spring 6 makes the steel bar in close contact with the multiple brush strips 8. When the rotating cylinder 3 rotates, it drives the brush strip 8 to rotate, so that the rotating brush strip 8 rust-removes the steel bar. The rust removed is discharged from the multiple chip removal grooves 3-2 opened on the rotating cylinder 3; when the brush strip 8 is severely worn and needs to be replaced after being used for a period of time, personnel rotate the cover 11 to remove the cover 11 from the internal thread sleeve 10, and manually extract the inserting strip 7 and the brush strip 8, and then replace the new inserting strip 7 and the brush strip 8. The operation is convenient, and personnel save time and effort.

[0026] There is a possible implementation. When the motor 12 is started, its output shaft drives the gear 13 to rotate. The gear 13 drives the meshing outer gear ring 14 to rotate. The outer gear ring 14 drives the rotating cylinder 3 to rotate, thereby realizing driving the rotating cylinder 3 to rotate by the motor 12.

[0027] There is a possible implementation. A pair of bearings 9 are arranged between the rotating cylinder 3 and the cover body 2 to reduce the friction between the rotating cylinder 3 and the cover body 2 through the bearings 9.

[0028] There is a possible implementation. A chip discharge port 1-1 is opened below the cover body 2 of the workbench, and devices such as an iron chip collection box are arranged at the chip discharge port 1-1 to collect the iron chips.

[0029] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
