The bottom surface of the fixed frame 18 is fixedly connected to the top surface of the chassis 1. The fixed frame 18 is a rectangular frame. Through holes II 1801 are provided on two parallel surfaces of the fixed frame 18. The two through holes II 1801 are coaxial. The driven gear 24 is rotatably connected inside the fixed frame 18. A central hole 2403 is provided in the center of the driven gear 24. The central hole 2403 is coaxial with the two through holes II 1801. The rust removal pipe 25 is fixedly connected inside the central hole 2403. The rust removal pipe 25 includes a straight pipe portion 2501, a flange portion 2502, and rust removal steel wire brush bristles 2503. The flange portion 2502 is fixedly connected to one end of the straight pipe portion 2501. The rust removal steel wire brush bristles 2503 are fixedly connected to the inner wall of the straight pipe portion 2501. The straight pipe portion 2501 is inserted into the central hole 2403. The flange portion 2502 is fixedly connected to the side wall of the driven gear 24 by screws. Holes for the screws to pass through are provided on the flange portion 2502. Screw holes for connecting the screws are provided on the side wall of the gear portion 2401. The inner diameter of the shaft tube portion 2402 is larger than the outer diameter of the flange portion 2502. Support tubes 19 are fixedly connected to the inner sides of the two side walls of the fixed frame 18 where the through holes II 1801 are provided. The inner diameter of the support tubes 19 is larger than the outer diameter of the shaft tube portion 2402. The shaft tube portion 2402 is rotatably connected inside the support tube 19. A bearing is connected between the shaft tube portion 2402 and the support tube 19. Support plates I 20 and support plates II 21 are respectively fixedly connected to the outer walls of the two support tubes 19. The support plate I 20 is arranged away from the motor III 22. The support plate II 21 is arranged close to the motor III 22. A round hole 2001 is provided on the support plate I 20. The round hole 2001 is fixedly connected to the outer wall of the end of the support tube 19 away from the fixed frame 18. The outer wall of the support plate I 20 is fixed to the inner wall of the fixed frame 18. An arc hole 2101 and a rectangular hole 2102 are provided on the support plate II 21. The arc hole 2101 and the rectangular hole 2102 are communicated. The arc hole 2101 is fixedly connected to the outer wall of the end of the support tube 19 away from the fixed frame 18. The motor III 22 is located inside the rectangular hole 2102. The inner diameter of the rectangular hole 2102 is larger than the outer diameter of the motor III 22.The outer wall of the second support plate 21 is fixed to the inner wall of the fixed frame 18.,

[0030] When the utility model is in use, the construction steel bars to be rust-removed are inserted through the through hole II 1801. The construction steel bars will move through the through hole II 1801, the shaft tube part 2402, the rust-removing tube 25, and the shaft tube part 2402 inside the rust-removing assembly 5, and then pass out from another through hole II 1801. The motor III 22 rotates to drive the driving gear 23 to rotate. The driving gear 23 rotates to drive the driven gear 24 to rotate. The driven gear 24 rotates to drive the rust-removing tube 25 to rotate. When the rust-removing tube 25 rotates, the rust-removing steel wire brush bristles 2503 brush and grind on the outer wall of the construction steel bars, so as to achieve the purpose of rust removal. After the whole construction steel bars pass through the rust-removing assembly 5, the rust removal is completed.

[0031] The support tube 19 is provided to rotatably support the shaft tube part 2402, so as to rotatably support the driven gear 24, which not only meets the rotation requirement of the driven gear 24 but also does not affect the passing of the construction steel bars.

[0032] The designs of the first support plate 20 and the second support plate 21 improve the structural stability of the support tube 19, thus ensuring the stability of the driven gear 24. Since the installation position of the second support plate 21 will interfere with the motor III 22, a rectangular hole 2102 needs to be opened on the second support plate 21 to avoid the motor III 22.

[0033] The flange part 2502 is fixedly connected to the side wall of the gear part 2401 by screws, so that the rust-removing tube 25 can be disassembled and replaced after the rust-removing steel wire brush bristles 2503 are worn out after long-term use.

[0034] When the utility model is in use, it should be noted that when the construction steel bars enter the rust-removing assembly 5, the staff needs to hold one end of the construction steel bars and push the construction steel bars into the rust-removing assembly 5. When the other end of the construction steel bars passes out of the rust-removing assembly 5 and the original held end is no longer sufficient to be held, the staff needs to hold the other end of the construction steel bars that have passed out of the rust-removing assembly 5 and continue to pull the construction completely out of the rust-removing assembly 5. When the staff pushes or pulls the construction steel bars, the construction steel bars should not rotate.

[0035] Since the movement track of the construction steel bars in the rust-removing tube 25 is a linear movement, the construction steel bars to be rust-removed using the utility model cannot be bent too much. For the bent construction steel bars, they need to be straightened first before using the utility model for rust removal.

[0036] When the utility model is in use, multiple rust removals can be carried out according to the rust-removing effect of the construction steel bars until the rust-removing effect meets the requirements.

[0037] The casters 3 are provided to facilitate the movement of the utility model. After moving to the designated position, the support legs 2 are adjusted so that the support legs 2 are stably seated on the ground, thus ensuring the normal and stable use of the utility model.

[0038] The use of the utility model eliminates the need for manual grinding and rust removal by staff, reduces the labor intensity of the staff, improves the rust removal work efficiency of construction steel bars, improves the rust removal quality, and at the same time, the utility model also avoids the spread of rust, prevents staff from inhaling rust, and ensures the physical health of the staff.

[0039] The above technical solution requires workers to push or pull construction steel bars. To further reduce the labor intensity of workers and improve the automation of the present utility model, on the basis of the above technical solution, the present utility model further includes a conveying assembly 4.

The two connecting pipes 12 are coaxial. The moving conveying shaft 13 includes a shaft portion Ⅱ1301, a clamping portion Ⅱ1302 and an arc groove Ⅱ1303. The clamping portion Ⅱ1302 is fixedly connected to the middle of the shaft portion Ⅱ1301. The arc groove Ⅱ1303 is provided on the outer wall of the clamping portion Ⅱ1302. The arc groove Ⅱ1303 is located directly above the arc groove Ⅰ803. Both ends of the shaft portion Ⅱ1301 are rotatably connected to the two connecting pipes 12 respectively. A bearing is provided between the shaft portion Ⅱ1301 and the connecting pipe 12. One end of the shaft portion Ⅱ1301 extends out of one connecting pipe 12. The motor Ⅱ10 is fixedly connected to the bottom surface of the end of the moving plate 9 that extends out of the rectangular hole Ⅱ603.

[0040] During use, place the construction steel bar on the arc groove Ⅰ803. The motor Ⅰ7 rotates to drive the conveying shaft 8 to rotate. The conveying shaft 8 rotates to drive the arc groove Ⅰ803 to rotate. The arc groove Ⅰ803 rotates to send the construction steel bar into the through hole Ⅱ1801.

[0041] The arc groove Ⅰ803 and the arc groove Ⅱ1303 clamp the construction steel bar therein. The rotation of the motor Ⅰ7 and the motor Ⅱ10 causes the arc groove Ⅰ803 and the arc groove Ⅱ1303 to drive the construction steel bar to move together, making the conveying effect of the construction steel bar better. The rotation directions of the motor Ⅰ7 and the motor Ⅱ10 are opposite.

[0042] Due to the settings of the moving plate 9, the connecting plate 11 and the connecting pipe 12, the motor Ⅱ10 and the moving conveying shaft 13 can slide up and down in the rectangular hole Ⅱ603, so that the arc groove Ⅰ803 and the arc groove Ⅱ1303 can clamp construction steel bars with different outer diameters.

[0043] When the moving plate 9 needs to move up and down, the adjusting rod 14 is rotated to drive the moving plate 9 to move up and down. The settings of the convex platform 1402, the limiting pipe 15 and the pressing plate 16 enable the connection between the adjusting rod 14 and the moving plate 9 to be rotatable but not separable, so that when the adjusting rod 14 rotates, it can drive the moving plate 9 to move up and down. The setting of the adjusting rod 14 also enables the arc groove Ⅰ803 and the arc groove Ⅱ1303 to exert a certain extrusion on the construction steel bar, to prevent the construction steel bar from sliding and rotating. The clamping part Ⅰ802 and the clamping part Ⅱ1302 can be made of rubber material, so as to further prevent the construction steel bar from sliding and rotating.

[0044] The motor Ⅱ10 and the motor Ⅰ7 are respectively arranged on both sides of the support frame 6, so as to prevent interference between the motor Ⅱ10 and the motor Ⅰ7 when the moving plate 9 moves up and down. The motor Ⅱ10 and the motor Ⅰ7 being respectively arranged on both sides of the support frame 6 also ensures the balance of the forces received on both sides of the support frame 6.

[0045] There are two conveying components 4, and the rust removal component 5 is arranged between the two conveying components 4. One of the two conveying components 4 is an input component and the other is an output component.

[0046] The setting of the two conveying components 4 realizes the pushing and pulling of the construction steel bar. To ensure that when one end of the construction steel bar extending out of the rust removal component 5 enters the conveying component 4 serving as the output component, the other end does not leave the conveying component 4 serving as the input component, the distance between the rust removal component 5 and the two conveying components 4 should not be too large, so as to prevent the construction steel bar from losing the conveying power during rust removal.
