Start the servo motor 11, the first fan blade 12 will rotate, and the first fan blade 12 will blow the metal dust and debris generated when cutting the steel bars to the first filter 16. At this time, a large amount of air will flow inside the ventilation pipe 13, driving the rotating shaft 17 to rotate slowly. At this time, the bristles 19 and the elastic scraper 10 clean the first filter 16, and sweep the dust and debris attached to the side wall of the first filter 16 into the dust box 15. The dust and debris generated during cutting can be collected by the first filter 16 and the bristles 19, thereby reducing the concentration of surrounding dust when the equipment is working, reducing the probability of dust inhalation by the staff, and facilitating the use of the equipment by the staff. At the same time, a large amount of air flow can reduce the temperature of the cutting tool on the surface of the equipment, thereby reducing the damage of the equipment cutting tool due to excessive temperature during long-term use.

[0029] Further, such as Figure 1 and Figure 4As shown, the top of the outer wall of the ventilation pipe 13 is fixedly connected to the water tank 2; the outer wall of the rotating shaft 17 is fixedly connected to the contact rod 21; the top of the outer wall of the ventilation pipe 13 is fixedly connected to the first support plate 22; the side wall of the first support plate 22 is rotatably connected to a connecting column 23; the outer wall of the connecting column 23 is fixedly connected to a sealing rod 24; the sealing rod 24 is in contact with the water tank 2; the outer wall of the sealing rod 24 is fixedly connected to a fixing column 25; the fixing column 25 is in contact with the contact rod 21; the outer wall of the first filter screen 16 is fixedly connected to a water absorption plate 26.

[0030] Further, such as Figure 1 and Figure 5 As shown, the side wall of the ventilation pipe 13 is fixedly connected to the spring 3; the side wall of the ventilation pipe 13 is in sliding contact with a sliding column 31; the outer side wall of the sliding column 31 is fixedly connected to the first scraper 32; the first scraper 32 is in contact with the elastic scraper 10; the first scraper 32 is in contact with the bristles 19; the first scraper 32 is not in contact with the fixed plate 18; the first scraper 32 is in contact with the first filter 16; the outer side wall of the sliding column 31 is fixedly connected to the fixed plate 33; the outer side wall of the spring 3 is fixedly connected to the fixed plate 33. The fixed plate 33 is pressed to move the sliding column 31, thereby positioning the first scraper 32 below the rotating shaft 17. When the elastic scraper 10 rotates, the first scraper 32 will contact the elastic scraper 10. During the contact, the elastic scraper 10 will be squeezed by the first scraper 32, thereby deforming the elastic scraper 10 itself. The first scraper 32 cleans and scrapes off the mixture attached to the side wall of the elastic scraper 10. By setting the first scraper 32 and the spring 3, the staff can clean the side wall of the elastic scraper 10 according to the actual situation, thereby reducing the effect of the elastic scraper 10 on cleaning the side wall of the first filter 16 due to excessive dust attached to the side wall of the elastic scraper 10 during long-term work, thereby increasing the stability of the equipment.

When the equipment is working, the water in the water tank 2 will store moving water, and the water in the water tank 2 will lift the float 41, thereby changing the height of the extension column 42 leaking out of the water tank 2. Through the provided float 41 and extension column 42, the staff can quickly observe the remaining water in the water tank 2, which is convenient for the staff to replenish the water in the water tank 2 in time, and is convenient for the staff to use and maintain the equipment.

When the device is working, the dust box 15 needs to be inside the dust box 14, and the limit block 51 is pulled to separate the limit block 51 from the support block 5. At this time, the dust box 15 can be separated from the device. When the limit block 51 is installed inside the support block 5, the limit block 51 limits the dust box 15, and the dust box 15 cannot move at this time. By setting the support block 5 and the limit block 51, the dust box 15 can be reduced from being accidentally pulled open when the device is working, and the dust can be reduced from being scattered due to accidentally opening the dust box 15, thereby increasing the stability of the device.

[0033] Further, such as Figure 7 As shown, two pairs of second support plates 6 are fixedly connected to the inner side wall of the dust box 15; a filter plate 61 is arranged on the top of the outer side wall of the second support plate 6; the filter plate 61 can be detached from the dust box 15. When the equipment is working, a mixture of water and dust will fall on the dust box 15, and the water will evaporate naturally.

[0034] Further, such as Figure 1 As shown, an observation plate 7 is provided on the outer wall of the dust box 14; the observation plate 7 is made of a transparent material. The staff can quickly understand the internal situation of the dust box 14 through the observation plate 7, and the observation plate 7 is provided to facilitate the staff to understand the internal situation of the dust box 14, so as to clean the dust box 15 in time.

[0035] Working principle: start the servo motor 11, the first fan blade 12 will rotate, and the first fan blade 12 will blow the metal dust and debris generated when cutting the steel bars to the first filter 16. At this time, a large amount of air will flow inside the ventilation pipe 13, driving the rotating shaft 17 to rotate slowly. At this time, the bristles 19 and the elastic scraper 10 clean the first filter 16, and sweep the dust and debris attached to the side wall of the first filter 16 into the dust collecting box 15. The dust and debris generated during cutting can be collected by the first filter 16 and the bristles 19, thereby reducing the concentration of surrounding dust when the equipment is working and the probability of dust inhalation by the staff, which is convenient for the staff to use the equipment.

In this case, clean water is injected into the water tank 2. When the rotating shaft 17 rotates slowly, the contact rod 21 will rotate accordingly. The contact rod 21 will move the fixing column 25, thereby rotating the sealing rod 24. At this time, the sealing rod 24 loses its seal on the hole at the bottom of the water tank 2. The water inside the water tank 2 drips into the surface of the water absorption plate 26 through the hole at the bottom. The water absorption plate 26 slowly soaks the water stored inside itself into the surface of the first filter screen 16. When the contact rod 21 passes through the fixing column 25, the fixing column 25 will reset due to its own gravity. At this time, the water tank 2 can no longer transport clean water to the inside of the water absorption plate 26. The water absorption plate 26 and the sealing rod 24 are set so that the surface of the first filter screen 16 can be Maintaining a certain degree of moisture increases the degree of dust condensation on the side wall of the first filter 16, making it easier for the elastic scraper 10 to clean the mixture of dust and water into the dust box 15, and reducing the probability of dust repeatedly falling off the side wall of the first filter 16 and being adhered to again due to the low weight of the dust. Pressing the fixed plate 33 moves the slide column 31, so that the first scraper 32 is located below the rotating shaft 17. When the elastic scraper 10 rotates, the first scraper 32 will contact the elastic scraper 10. When in contact, the elastic scraper 10 will be squeezed by the first scraper 32, so that the elastic scraper 10 itself is deformed, and the first scraper 32 cleans and scrapes off the mixture attached to the side wall of the elastic scraper 10. By setting the first scraper 32 and the spring 3, the staff can The side wall of the elastic scraper 10 is cleaned according to actual conditions to reduce excessive dust adhering to the side wall of the elastic scraper 10 during long-term operation, thereby reducing the effect of the elastic scraper 10 on cleaning the side wall of the first filter 16 and increasing the stability of the equipment. When the equipment is working, the water in the water tank 2 will store moving water, and the water in the water tank 2 will lift the float 41, thereby changing the height of the water tank 2 leaking out of the extension column 42. By setting the float 41 and the extension column 42, the staff can quickly observe the remaining water in the water tank 2, which is convenient for the staff to replenish the water in the water tank 2 in time, and is convenient for the staff to use and maintain the equipment. When the equipment is working, the dust box 15 needs to be inside the dust box 14.Pull the limit block 51 to separate the limit block 51 from the support block 5. At this time, the dust box 15 can be separated from the device. When the limit block 51 is installed into the support block 5, the limit block 51 limits the dust box 15. At this time, the dust box 15 cannot move. The support block 5 and the limit block 51 are set to reduce the possibility of the dust box 15 being accidentally pulled open when the device is working, reduce the possibility of dust escaping due to accidental opening of the dust box 15, and increase the stability of the device. When the device is working, a mixture of water and dust will fall into the dust box 15, and the water will evaporate naturally. The second support plate 6 intercepts the mixture to a certain extent, separates part of the water from the dust, and facilitates the dust mixture to agglomerate above the second support plate 6. The second support plate 6 and the filter plate 61 are provided to facilitate the staff to classify the dust mixture, and at the same time increase the area of ​​water in the air, accelerate the evaporation rate of water, and facilitate the collection of dust by the staff. The staff can quickly understand the internal situation of the dust box 14 through the observation plate 7.
