When the first double-acting cylinder 4 is started, the first double-acting cylinder 4 drives the first support frame 10 to move up and down along one side of the first fixing frame 2.

[0043] A support assembly 7 for placing the scrap steel is provided on the top of the bottom plate 11 on one side of the first support frame 10. The support assembly 7 includes a second support frame 703 fixed to the top of the bottom plate 11 by bolts, a support plate 701 is slidably connected to the top of the second support frame 703 through a sliding table, a through-threaded groove is formed in the top of the second support frame 703, a lead screw 702 whose one end contacts and forms an extrusion state with the support plate 701 is threadedly connected in the threaded groove. The scrap steel is placed on the top of the support plate 701, the lead screw 702 is rotated to disengage the lead screw 702 from the support plate 701, then the scrap steel is held by hand and the support plate 701 is pushed at the same time. The support plate 701 drives the scrap steel to move between the first clamping plate 801 and the second clamping plate 802, and then the lead screw 702 is rotated to make the lead screw 702 contact and form an extrusion state with the support plate 701. The scrap steel is clamped by the first clamping plate 801 and the second clamping plate 802, so that it is not necessary for the staff to always hold the scrap steel by hand and then clamp it, which not only reduces the operation difficulty, but also greatly reduces the working intensity of the staff.

[0044] On one side inner wall of the first support frame 10, there is a flipping and clamping assembly 8 for rotating and fixing the scrap steel. On the bottom inner wall of the first support frame 10, there is an inclined plane 12 that slopes downward from top to bottom. On one side of the first fixing frame 2, there is a through-type material discharging opening 13. At the top of the bottom plate 11 at the position of the material discharging opening 13, there is a material collecting assembly 3 for collecting the scrap steel after rust removal. The material collecting assembly 3 includes a collecting box 306 placed on the top of the bottom plate 11, and the collecting box 306 is in contact with the inner wall of the first fixing frame 2. On the top of the bottom plate 11, there is a locking mechanism for fixing the collecting box 306. The locking mechanism includes two connecting frames 304 symmetrically arranged and fixed to the top of the bottom plate 11 by bolts. On one side of each of the two connecting frames 304, there are two guide rods 305 fixed by bolts. On the outer circumferences of the two guide rods 305, there are first sliding frames 303 slidably connected. At one end of the two first sliding frames 303, there is an L-shaped plate 301 whose inner wall is in contact with the collecting box 306. At the end of the guide rod 305 opposite to the connecting frame 304, there is a magnet 302 fixed by bolts. By sliding the first sliding frame 303 along the guide rod 305, the inner wall of the L-shaped plate 301 is in contact with the collecting box 306, and at the same time, the magnet 302 adsorbs to the first sliding frame 303, thereby realizing the fixation of the collecting box 306 and preventing the collecting box 306 from shifting during use. The collecting box 306 facilitates the collection of the scrap steel after rust removal. Place the scrap steel on the top of the support assembly 7, push the support assembly 7 to push the scrap steel to the position of the flipping and clamping assembly 8, so that it is not necessary for the staff to always hold the scrap steel by hand for clamping, greatly reducing the work intensity of the staff. Then start the flipping and clamping assembly 8, the flipping and clamping assembly 8 clamps the scrap steel, start the driving assembly, the driving assembly drives the first support frame 10 to move upward, so that the first support frame 10 contacts the protective shell 1 and forms a closed state, thereby realizing the protection during the rust removal process. The flipping and clamping assembly 8 flips the scrap steel, facilitating the rust removal component 6 to rust other surfaces of the scrap steel. The scrap steel after rust removal slides down the inclined plane 12 through the material discharging opening 13 and falls into the material collecting assembly 3, thereby automatically collecting the scrap steel after rust removal.

[0045] Particularly in the present invention, the flipping and clamping assembly 8 includes a first clamping plate 801 rotatably connected to the inner wall of one side of the first support frame 10 through a bearing. On the inner wall of the other side of the first support frame 10, there is a rotating shaft 806 rotatably connected. Inside the rotating shaft 806, there is a threaded rod 804 rotatably connected to the first support frame 10 through a bearing. On one side of the rotating shaft 806, there are two telescopic rods 805 fixed by bolts. At the other ends of the two telescopic rods 805, there is a second sliding frame 803 threadedly connected to the threaded rod 804. On the side of the second sliding frame 803 opposite to the telescopic rod 805, there is a second clamping plate 802 fixed by bolts. Between the inner walls of the two sides of the first support frame 10, there is a flipping assembly 9 for driving the first clamping plate 801 and the rotating shaft 806 to rotate.

[0046] The flipping assembly 9 includes a connecting shaft 901 rotatably connected between the inner walls on both sides of the first support frame 10 through bearings. On the outer circumference of both ends of the connecting shaft 901, second gears 902 are connected by keys. On the outer circumference of the first clamping plate 801 and the rotating shaft 806, third gears 903 meshing with the second gears 902 are connected by keys. On one side of the first support frame 10, a self-locking motor for driving the connecting shaft 901 to rotate along the axis is fixed by bolts. When the self-locking motor is started, the self-locking motor drives the connecting shaft 901 to rotate. The connecting shaft 901 drives the two second gears 902 to rotate simultaneously. The two second gears 902 drive the two third gears 903 to rotate simultaneously. The two third gears 903 drive the first clamping plate 801 and the rotating shaft 806 to rotate respectively. The rotating shaft 806 drives the second clamping plate 802 to rotate through the second carriage 803, thereby realizing the flipping of the scrap steel clamped by the first clamping plate 801 and the second clamping plate 802, facilitating the rust removal of other surfaces of the scrap steel, and eliminating the need for manual frequent flipping of the scrap steel by workers, thus greatly reducing the consumption of time and manpower.

[0047] On one side of the protective shell 1, there is a rotating assembly 5 for rotating the threaded rod 804. The rotating assembly 5 includes a second double-acting cylinder 501 fixed to one side of the protective shell 1 by bolts. On the two piston ends of the second double-acting cylinder 501, racks 502 are fixed by bolts. On the outer circumference of the threaded rod 804 on the outer wall of one side of the first support frame 10, a first gear 503 is connected by a key. After the rust removal is completed, the second double-acting cylinder 501 is started. The second double-acting cylinder 501 drives the rack 502 to engage with the first gear 503. The first double-acting cylinder 4 drives the first support frame 10 to move downward. The first support frame 10 drives the threaded rod 804 and the first gear 503 to move downward. At the same time, the rack 502 drives the first gear 503 to rotate. The first gear 503 drives the threaded rod 804 to rotate clockwise. The rotation of the threaded rod 804 drives the second carriage 803 and the second clamping plate 802 to move away from the first clamping plate 801, so that the rust-removed scrap steel is released from the fixation, eliminating the need for manual operation by workers, not only greatly improving the work efficiency, but also reducing the labor intensity of workers. By manually rotating the threaded rod 804 counterclockwise, the threaded rod 804 drives the second carriage 803 to slide along the extending direction of the telescopic rod 805. By the mutual approach of the first clamping plate 801 and the second clamping plate 802, the scrap steel is quickly clamped.

[0048] It should be noted that the laser rust remover 603 is a prior art, which consists of a laser, a rust removal head, a laser controller, a focusing system, etc. Those skilled in the art can set it according to actual needs and will not be elaborated here.

[0049] When the present invention is used, it is divided into the following steps:

[0050] S1: Place the scrap steel on top of the support plate 701. Rotate the lead screw 702 so that the lead screw 702 is disengaged from the support plate 701. Then, while holding the scrap steel by hand, push the support plate 701. The support plate 701 drives the scrap steel to move between the first clamping plate 801 and the second clamping plate 802. Then rotate the lead screw 702 so that the lead screw 702 contacts the support plate 701 and forms a squeezing state.

[0051] S2: Then manually rotate the threaded rod 804 counterclockwise. The threaded rod 804 drives the second carriage 803 to slide along the direction of the telescopic rod 805. The scrap steel is quickly clamped by the cooperation of the first clamping plate 801 and the second clamping plate 802.

[0052] S3: Then rotate the lead screw 702 so that the lead screw 702 is disengaged from the support plate 701. Pull the support plate 701 to reset the support plate 701. Then rotate the lead screw 702 so that the lead screw 702 contacts the support plate 701 and forms a squeezing state.

[0053] S4: Then start the first double-acting cylinder 4. The first double-acting cylinder 4 drives the first support frame 10 to move upward along one side of the first fixed frame 2. The first support frame 10 drives the flipping and clamping assembly 8 and the clamped scrap steel to move upward. The first support frame 10 contacts the protective shell 1 and forms a closed state.

[0054] S5: Then start the linear motor 602. The linear motor 602 drives the laser rust remover 603 to move left and right to remove rust from the scrap steel. After the top surface rust removal is completed, start the self-locking motor. The self-locking motor drives the connecting shaft 901 to rotate. The connecting shaft 901 drives the two second gears 902 to rotate simultaneously. The two second gears 902 drive the two third gears 903 to rotate simultaneously. The two third gears 903 drive the first clamping plate 801 and the rotating shaft 806 to rotate respectively. The rotating shaft 806 drives the second clamping plate 802 to rotate through the second carriage 803, turning over the scrap steel clamped by the first clamping plate 801 and the second clamping plate 802. Then continue to remove rust from the scrap steel with the laser rust remover 603, and so on.

[0055] S6: Then after the rust removal is completed, start the second double-acting cylinder 501. The second double-acting cylinder 501 drives the rack 502 to engage with the first gear 503. The first double-acting cylinder 4 drives the first support frame 10 to move downward. The first support frame 10 drives the threaded rod 804 and the first gear 503 to move downward. At the same time, the rack 502 drives the first gear 503 to rotate. The first gear 503 drives the threaded rod 804 to rotate clockwise. The threaded rod 804 drives the second clamping plate 802 to move backward through the second carriage 803, so that the rust-removed scrap steel is released from the fixation.

[0056] S7: Finally, the rust-removed scrap steel slides down along the inclined plane 12 and falls into the collection box 306 through the discharge port 13.

[0057] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0058] The above-described embodiments only express several implementation manners of the present invention, and the description is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
