The upper arc plate 5 is fixedly connected to the connecting piece 4. The upper arc plate 5 is adapted to the lower arc plate 3. Through the coordinated design of the motor 11, the bevel gear 10, the bevel gear 19, the round tube 20, the threaded rod 18, the scraper 7 and the collecting box 19, when the debris is pushed to the position of the through hole, the debris falls into the collecting box 19 through the through hole 18, thereby achieving the effect of automatically cleaning and collecting the debris.

[0032] In this embodiment, arc-shaped magnet plates 6 are fixedly mounted on the upper arc plate 5 and the lower arc plate 3, and rubber plates 17 are fixedly mounted at both ends of the upper arc plate 5 and the lower arc plate 3. The magnetic force of the two arc-shaped magnet plates 6 can further prevent debris from splashing.

[0033] In this embodiment, the cleaning mechanism includes a scraper 7, a threaded rod 8, a round tube 20, a bevel gear 9, a bevel gear 10 and a motor 11. A scraper 7 is provided between the upper arc plate 5 and the lower arc plate 3. A threaded rod 8 is fixedly connected to the scraper 7. A round tube 20 is threadedly connected to the threaded rod 8. The round tube 20 is rotatably connected to one of the two fixed plates. The drive of the motor 11 can achieve the effect of automatically cleaning the debris between the upper arc plate 5 and the lower arc plate 3.

[0034] In this embodiment, the motor 11 is fixedly installed on the workbench 1, and the output end of the motor 11 is fixedly connected to the bevel gear 2 10, and the bevel gear 10 is meshed with the bevel gear 1 9, and the bevel gear 1 9 is fixedly connected to one end of the circular tube 20 for transmission and is a detachable connection.

[0035] In this embodiment, one end of the threaded rod 8 passes through the bevel gear 9, and the round tube 20 is provided with an internal thread to facilitate transmission between the round tube 20 and the threaded rod 8.

[0036] In this embodiment, the detection mechanism includes a cylinder 12, a U-shaped plate 13, a threaded rod 14 and a clamp 15. The cylinder 12 is fixedly installed on the two fixed plates.

[0037] In this embodiment, through holes 18 are provided on the lower arc plate 3 , the workbench 1 and the corresponding rubber plate 17 , so as to facilitate the debris to fall into the collection box 19 .

[0038] In this embodiment, a collecting box 19 is fixedly installed at the bottom of the workbench 1. The collecting box 19 corresponds to the through hole 18 and is used to collect debris.

[0039] Working principle: When in use, first open the upper arc plate 5, then place the two ends of the building steel bar 16 between the two U-shaped plates 13 and the clamping plate 15 respectively, and rotate the two threaded rods 14 so that the two clamping plates 15 clamp and fix the two ends of the building steel bar 16.

At the same time, the bevel gear 1 9 drives the round tube 20 to rotate on the corresponding fixed plate 1. At the same time, the round tube 20 and the threaded rod 1 8 are threadedly transmitted, so that the threaded rod 1 8 pushes the scraper 7 to move to the left between the upper arc plate 5 and the lower arc plate 3, and the scraper 7 scrapes off the debris adsorbed on the two arc magnet plates 6 and pushes the debris to the left. When the debris gradually separates from the two arc magnet plates 6, the debris continuously slides onto the lower arc plate 3. Afterwards, when the debris is pushed to the position of the through hole 18, the debris falls into the collection box 19 through the action of the through hole 18, thereby achieving the effect of automatically cleaning and collecting the debris.

[0043] The technical progress achieved by the utility model compared with the prior art is that through the cooperation of various components, it can not only achieve the purpose of preventing the flying debris from the collapse and improving safety, but also realize the purpose of automatically cleaning and collecting the debris and improving convenience. In addition, it has a simple structure and is more practical.
