A positioning rod 8 is threadedly connected to the connecting plate 6 and the end of the positioning rod 8 is inserted into the receiving collection frame 7. The collection frame 7 can be easily installed and removed by removing the positioning rod 8. Sieve holes are evenly opened on the bottom side of the collection frame 7, and the sieve holes are used for further discharge of the coolant. One side of the collection frame 7 is in contact with a pad 11, and a pad 11 is provided to provide support. The pad 11 is fixedly connected to the collection frame 3, and a liquid guide port 12 is fixedly connected to the side of the collection frame 3 away from the collection frame 7, and the liquid guide port 12 is used to discharge powder in the coolant.

[0018] The combing rod 10 is fixedly connected to the support rod 9, and the support rod 9 is fixedly connected in the collecting frame 7. By setting the combing rod 10 and contacting with the conveyor belt 5, the metal debris can be scraped off.
