[0002] Steel bar rust removal is an important part of construction. Some steel bars that have been installed or piled at the construction site will have rust on their surfaces due to long-term exposure to the air. There are usually two ways to remove rust: chemical rust removal and physical rust removal.

[0025] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] In one embodiment, see Figures 1 - 10 The rust removal box of steel bars comprises a stacking base 1, a blocking plate 2 facing forward and backward is vertically arranged on the right side of the upper surface of the stacking base 1, and a guide platform 5 facing the upper left is arranged on the left side of the stacking base 1. When the transportation equipment pours the steel bars on the guide platform 5, the steel bars will slide along the guide platform 5 in the forward and backward direction to the bottom of the stacking base 1 and be blocked by the blocking plate 2. In order to ensure the stability of the guide platform 5, an auxiliary support plate 6 fixedly connected to the stacking base 1 is arranged below the guide platform 5, and in order to keep the blocking plate 2 in a vertical state, a diagonal reinforcement rib 7 is arranged between the blocking plate 2 and the stacking base 1. Therefore, the stacking effect of steel bars is achieved through the guide platform 5 and the blocking plate 2, and for the overall aesthetics, a shell can also be wrapped around the outside of the entire stacking base 1, so that the entire rust removal device is located inside the box, and also includes a grabbing mechanism 3 and a grinding mechanism 4; The material grabbing mechanism 3 includes a vertically arranged clearance gap 8, which is evenly distributed from front to back along the upper side of the blocking plate 2, and the upper end of the clearance gap 8 is in an open state. A driving roller 9 arranged in a front-to-back direction is rotatably connected to the upper end of the clearance gap 8, and a guide roller 13 arranged in a front-to-back direction is arranged below the clearance gap 8. The outside of the driving roller 9 and the guide roller 13 is wrapped with an annular feeding belt 10, and a grabbing hook 11 is arranged on the outside of the feeding belt 10. The feeding belt 10 passes through the clearance gap 8 and extends to the left side of the blocking plate 2. The feeding belt 10 located on the left side of the blocking plate 2 remains in a vertical state. When the feeding belt 10 rotates clockwise, the grabbing hook 11 can hook the steel bars at the bottom and move upward. When the grabbing hook 11 moves with the feeding belt 10, the steel bars will move to the upper right side of the blocking plate 2, thereby realizing the steel bar picking effect, and only one steel bar is taken out each time; The grinding mechanism 4 includes a material guide plate 36 arranged above the right side surface of the blocking plate 2. The material guide plate 36 is facing the lower right. Vertical plates 38 are vertically arranged on the front and rear sides of the upper end of the blocking plate 2. The upper end of the vertical plate 38 is rotatably connected to the left end of the deflection beam 33, and the right end of the deflection beam 33 is rotatably connected to the left end of the rotating arm 34. A plurality of grinding rollers 35 arranged in a front-to-back direction are evenly distributed on the rotating arm 34 from left to right. Therefore, under the action of gravity, the grinding rollers 35 can fall on the material guide plate 36.

[0027] In one case of this embodiment, a driving shaft 19 arranged in a front-to-back direction is provided at the upper end of the blocking plate 2, and the driving shaft 19 drives the driving roller 9 to rotate, and a first driving motor 16 is provided at the front side of the blocking plate 2, and the output shaft of the first driving motor 16 is fixedly connected to the first bevel gear 17, and the first bevel gear 17 is meshedly connected to the second bevel gear 18 fixedly connected to the end of the driving shaft 19. Therefore, the output shaft of the first driving motor 16 rotates the driving shaft 19 through gear transmission, so that the driving roller 9 can synchronously rotate clockwise. A support seat 27 is slidably connected to the middle of the clearance gap 8, and the support seat 27 can move up and down along the clearance gap 8. A support frame 12 is arranged on the upper surface of the support seat 27, and the upper end of the support frame 12 is rotatably connected to the guide roller 13, so that the up and down movement of the support seat 27 can control the up and down movement of the guide roller 13. When the guide roller 13 moves downward, the feeding belt 10 on the left side will move downward, so that as the guide roller 13 descends, the steel bars in the lower position are taken out, and a lifting component 15 is arranged on the right side of the upper surface of the stacking base 1, and the lifting component 15 can push the support seat 27 to move up and down. At the same time, a tensioning component 14 is arranged at the right end of the stacking base 1, and the tensioning component 14 can keep the feeding belt 10 in a tensioned state.

[0028] In one case of this embodiment, the tensioning assembly 14 includes a tensioning cantilever 20 rotatably connected to the right end of the stacking base 1, the tensioning cantilever 20 is facing the upper right state, and a tensioning bracket 21 is provided at the upper end of the tensioning cantilever 20, and the upper end of the tensioning bracket 21 is rotatably connected to a tensioning roller 22 arranged in a front-to-back direction, and the outside of the tensioning roller 22 is wrapped with the feeding belt 10. Under the action of gravity, the tensioning cantilever 20 will rotate clockwise, and the tensioning roller 22 will pull the feeding belt 10 to the right, so that the feeding belt 1 0 will be in a tensioned state, the upper end of the counterweight rod 24 is rotatably connected to the upper right side of the tensioning cantilever 20, the lower end of the counterweight rod 24 is fixedly connected to the counterweight block 23, and a first limit block 25 is set in the middle of the counterweight rod 24, and a first push rod 26 is rotatably connected to the middle of the tensioning cantilever 20. After the counterweight rod 24 is lifted, the first push rod 26 can support the first limit block 25, so that the counterweight rod 24 is propped up, which increases the driving force for the tensioning cantilever 20 to rotate to the right, so that the tensioning effect of the feeding belt 10 is better.

[0029] In one case of the present embodiment, the lifting assembly 15 includes a bearing seat 28 arranged on the front and rear sides of the right end of the stacking base 1, and the bearing seat 28 is rotatably connected to an adjusting screw rod 29 arranged in a front-to-rear direction, and threads with opposite rotation directions are arranged on the front and rear sides of the adjusting screw rod 29, and push-pull nuts 30 are threadedly connected to the front and rear sides of the adjusting screw rod 29, and the upper surface of the push-pull nut 30 is rotatably connected to the lower end of the top plate 31, and the upper end of the top plate 31 is rotatably connected to the front and rear sides of the lower surface of a support plate 32 arranged in a front-to-rear direction, and the upper surface of the support plate 32 is fixedly connected to the right side of the support seat 27, so when the adjusting screw rod 29 rotates, the two push-pull nuts 30 move closer to each other or move away from each other, and the support plate 32 moves up and down, so that the support seat 27 drives the guide roller 13 to move up and down, thereby realizing the adjustment of the minimum height of the feeding belt 10.

[0030] In one case of the present embodiment, a rotating sleeve 42 arranged in a front-to-back direction is fixedly connected to the right end of the deflection beam 33, and the end of the rotating sleeve 42 is rotatably connected to the left end of the rotating arm 34, so that the rotating arm 34 is rotated around the right end of the deflection beam 33 through the rotating sleeve 42, so that the rotating arm 34 will adaptively deflect, so that the grinding roller 35 can fall on the guide plate 36, and a driving rod 43 arranged in a front-to-back direction is rotatably connected to the middle part of the rotating sleeve 42, and the middle part of the driving rod 43 is fixedly connected to the grinding roller 35, and a second driving motor 39 is arranged on the right side of the deflection beam 33 on the front side, and the output shaft of the second driving motor 39 is fixedly connected to the third bevel gear 40, and the third bevel gear 40 is meshingly connected to the fourth bevel gear 41 fixedly connected to the end of the driving rod 43. The second drive motor 39 rotates the drive rod 43 through gear transmission, thereby rotating the leftmost grinding roller 35, and a synchronous belt can be set at the end of the grinding roller 35, so that the multiple grinding rollers 35 on the rotating arm 34 can rotate synchronously in the same direction, or the grinding roller 35 connected to the drive rod 43 is removed, and the other grinding rollers 35 are rotatably connected to the rotating arm 34, and a damping block is set at the connection position, which can limit the rotation of the grinding roller 35. Therefore, when the steel bar rolls to the right along the upper surface of the guide plate 36, the rotation speed of the grinding roller 35 will be lower, that is, there is a speed difference between these adaptively rotating grinding rollers 35 and the steel bar, so that the steel bar is ground and rusted by the grinding roller 35.

[0031] In one case of this embodiment, the left end of the guide plate 36 is rotatably connected to the right side of the blocking plate 2, and a second stopper 45 is arranged on the lower surface of the guide plate 36, which is rotated to the left end of the second push rod 46 above the right side of the blocking plate 2, so that when the guide plate 36 is lifted, the second push rod 46 can support the second stopper 45, so that the angle of the guide plate 36 is locked, achieving the effect of angle fixing. In addition, the left end of the guide belt 37 is connected to the right end of the guide plate 36, and the right side of the guide belt 37 falls on the ground, so that the steel bar will fall on the guide belt 37 after sliding to the right along the guide plate 36. The belt 37 is a piece of cloth belt, so the steel bar will move to the right along the guide belt 37 again and finally fall to the ground, achieving a buffering effect. At the same time, a winding roller 44 is arranged on the right end of the lower surface of the guide plate 36. When the guide belt 37 is not needed, the guide belt 37 can be wound on the winding roller 44.

[0032] During the implementation of this embodiment, if the long strips of steel bars piled up at the construction site are rusted, the rust removal box can be moved to the construction site by means of transportation equipment.

[0033] To start the process, first lift the guide plate 36 and support the second push rod 46 on the second limit block 45. At this time, the guide platform 5 is lifted and tilted to the lower right, and the guide belt 37 is pulled out from the winding roller 44. The right side of the guide belt 37 falls to the ground under the action of gravity, and the right end of the guide belt 37 can also be fixed to the ground. At this time, the deflection beam 33 is rotated clockwise so that the rotating arm 34 falls on the guide plate 36, and the grinding roller 35 is placed on the guide plate 36 under the action of gravity. The counterweight rod 24 is lifted and the counterweight rod 24 is supported by the first push rod 26. The feeding belt 10 is tightened, and the adjusting screw 29 is rotated to move the support seat 27 upward, so that the guide roller 13 is lifted. At this time, the preparation process is completed, and the steel bars are dumped onto the guide platform 5 through some handling machinery. At this time, the rust removal process can be started.

[0034] After rust removal, the second drive motor 39 is started, the grinding roller 35 starts to rotate, the first drive motor 16 is started, and the feeding belt 10 starts to rotate clockwise. When the grab hook 11 rotates to the lower left side of the feeding belt 10, the grab hook 11 hooks up the top steel bar, and the steel bar moves upward with the grab hook 11. When the steel bar moves to the right side over the blocking plate 2, the steel bar moves to the lower right with the feeding belt 10. The inclination angle of the feeding belt 10 is greater than the guide plate 36 at this time, so the steel bar will eventually fall on the guide plate 36, and the steel bar continues to move to the right along the guide plate 36. When the steel bar moves to the bottom of the grinding roller 35, the rotating grinding roller 35 will grind and remove rust from the surface of the steel bar. After the rust is removed, the steel bar will fall onto the guide belt 37 and finally fall to the ground along the guide belt 37, thereby completing the grinding process of the entire steel bar. As the steel bars on the stacking base 1 are continuously taken away, the adjusting screw 29 is rotated to move the guide roller 13 downward, so that the left side of the feeding belt 10 is continuously lowered, thereby continuously transferring steel bars of different heights, and finally removing rust from the steel bars on the entire stacking base 1.

[0035] The present invention is applicable to a steel bar derusting box, which continuously rotates clockwise by arranging a feeding belt 10 with a grab hook 11, so that the steel bars piled on the pile base are transferred one by one to the guide plate 36, and the steel bars are derusted by the rotating grinding roller 35. During the whole derusting process, there is no need to manually carry the steel bars, which reduces the labor intensity and improves the efficiency of derusting.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
