[0020] In the conventional cutting machine, the dust removal method mostly adopts fixedly installed air exhaust equipment. However, since the cutting operation is often not carried out in a fixed position, the cutting path and range of the cutting assembly will change constantly according to the shape of the workpiece, processing requirements and other factors, and the fixed air exhaust equipment is difficult to fully cover the cutting area, and the area far away from the cutting position becomes a dust removal dead angle, and the dust cannot be effectively exhausted in time.

[0021] Therefore, the present application provides a mobile dust removal device, which refers to Figures 1-5 It comprises a bed body 100, a dust collection chamber 200, a first driving device 300, a cross beam 400, an air exhaust assembly 500, a cutting assembly 600 and two first guide rails 700, the two first guide rails 700 are arranged in parallel on both sides of the top of the bed body 100, the dust collection chamber 200 is slidably connected with the first guide rail 700, the bottom of the dust collection chamber 200 is open and forms a cutting space, the first driving device 300 is arranged on the dust collection chamber 200, the first driving device 300 drives the dust collection chamber 200 to move along the first guide rail 700, the cross beam 400 is arranged in the cutting space and is arranged perpendicularly to the first guide rail 700, the two ends of the cross beam 400 are fixedly connected with the two side inner walls of the dust collection chamber 200 respectively, the cutting assembly 600 is arranged on the top of the cross beam 400, and the air exhaust assembly 500 is arranged at the bottom of the cross beam 400, so as to move synchronously with the cross beam 400 and follow the cutting area to perform air exhaust and dust removal.

[0022] The bed body 100 provides a support platform; the cutting space is enclosed by the bottom opening of the dust collection chamber 200, which facilitates the collection of dust generated by cutting; the dust collection chamber 200 is driven by the first driving device 300 to move on the first guide rail 700, so as to drive the beam 400 and the cutting assembly 600 and the air extraction assembly 500 installed on the beam 400 to follow the change of the cutting position, thereby ensuring the synchronization of cutting and dust removal. By setting the dust collection chamber 200 that can move along the guide rail, and installing the air extraction assembly 500 at the bottom of the beam 400 that moves synchronously with the cutting assembly 600, the air extraction and dust removal of the cutting area can be realized, the dust generated by cutting can be captured in time and accurately, the dead angle of dust removal can be reduced, the dust removal efficiency can be improved, and the air quality of the working environment can be effectively improved; the cutting and dust removal functions are reasonably integrated in space, the structure is compact, the overall equipment occupies less space, and the arrangement and use in different scale working sites are facilitated.

[0023] During the cutting process, the cutting space enclosed by the bottom opening of the dust collection chamber 200 helps to gather dust, so that the dust cannot easily spread to the outside; the cutting assembly 600 cuts the workpiece on the beam 400 according to the processing requirements and generates dust; at the same time, the beam 400 with the air extraction assembly 500 moves along the first guide rail 700 synchronously with the movement of the cutting assembly 600, and the air extraction assembly 500 continuously extracts the dust generated by cutting, and always maintains effective coverage of the cutting area until the entire cutting operation is completed; when the air extraction assembly 500 operates, the dust generated in the cutting area is sucked away by the suction force generated by the air extraction assembly 500, thereby achieving the effect of following air extraction and dust removal and reducing dust pollution. The cutting assembly 600 is a prior art, and its specific structure and working principle will not be described again.

[0024] In one embodiment, the first driving device 300 includes a rack 310, a gear and a motor 320, the rack 310 is arranged on the bed body 100 and arranged in parallel with the first guide rail 700, the motor 320 is fixedly arranged on the dust collection chamber 200, the gear is coaxially arranged with the output end of the motor 320, and the gear is engaged with the rack 310. The motor 320 drives the gear to roll along the rack 310, thereby driving the dust collection chamber 200 to move along the first guide rail 700, controlling the moving direction and position of the dust collection chamber 200, ensuring that the cutting area is always effectively covered during the cutting process, and improving the comprehensiveness of dust removal.

[0025] During the moving process, the dust collection chamber 200 may shake or tilt due to uneven center of gravity or uneven force. Thus, in an embodiment, the mobile dust removal device further comprises a support seat 800 and a sliding block 810, the support seat 800 is arranged at the bottom of the dust collection chamber 200, the sliding block 810 is arranged at the bottom of the support seat 800, and the sliding block 810 is in sliding connection with the first guide rail 700. By arranging the support seat 800 at the bottom of the dust collection chamber 200 and configuring the sliding block 810 at the bottom of the support seat 800, the dust collection chamber 200 is subjected to force at multiple points and the force is more uniform when moving along the first guide rail 700, which can effectively avoid the shaking, deviation and other unstable conditions of the dust collection chamber 200 during the moving process, ensure that the dust collection chamber 200 can move smoothly and accurately, and ensure the smooth progress of the dust removal work.

[0026] During a long period of use, especially under the influence of vibration, impact force and other factors generated by frequent movement and cutting operation, the connection between the cross beam 400 and the dust collection chamber 200 may loosen. Thus, in an embodiment, the mobile dust removal device further comprises a support frame, one end of the support frame is fixedly connected with the cross beam 400, and the other end of the support frame is fixedly connected with the inner side wall of the dust collection chamber 200; at least two support frames are arranged along the length direction of the cross beam 400. By arranging at least two support frames, the cross beam 400 is stably connected with the inner side wall of the dust collection chamber 200, so that the cross beam 400 can better resist various external forces, such as vibration generated during cutting, inertial force during moving, etc., when carrying the cutting assembly 600 and the air suction assembly 500 and moving with the dust collection chamber 200 and carrying out cutting operation, avoiding loosening and deformation between the cross beam 400 and the dust collection chamber 200, ensuring the stability of the structure of the entire mobile dust removal device, and ensuring the continuous and stable development of the dust removal work.

[0027] When the dust collection chamber 200 moves, the cable can be pulled and broken, causing the electrical connection to be interrupted and the cutting assembly 600 to malfunction. Therefore, in an embodiment, a side wall of the dust collection chamber 200 is provided with a drag chain outlet 210, and the mobile dust removal device further comprises a drag chain rack, which comprises a support 830 and a plurality of groups of rollers 840. The support 830 is fixedly arranged on one side of the bed body 100 and extends along the length direction of the first guide rail 700. All the rollers 840 are arranged on the top of the support 830 and can rotate relative to the support 830 along the length direction of the first guide rail 700. The drag chain is used to connect the external equipment and the cutting assembly 600 in the dust collection chamber 200, to ensure stable power supply and accurate control signal. The plurality of groups of rollers 840 on the drag chain rack are arranged along the length direction of the first guide rail 700 and can rotate relative to the support 830, which supports and guides the drag chain, reduces the friction and pulling between the drag chain and other components, and maintains the neatness and stability of the entire device during operation.

[0028] The air suction coverage can be limited and can not effectively cover the entire cutting area. Therefore, in an embodiment, the air suction assembly 500 comprises a first air suction pipe 510, a second air suction pipe 520, an air suction box 530, and a fan. The first air suction pipe 510 is arranged on the bottom of the cross beam 400 along the length direction of the cross beam 400. The first air suction pipe 510 is provided with a plurality of air suction openings communicating with the cutting space. The second air suction pipe 520 is arranged on the bed body 100 and is arranged in parallel with the first guide rail 700. The air suction box 530 is arranged on the cross beam 400. The side surface of the air suction box 530 communicates with the end of the first air suction pipe 510. The bottom surface of the air suction box 530 is in sliding connection with the second air suction pipe 520 and communicates therewith. The fan is fixedly arranged on the bed body 100. The air inlet end of the fan communicates with the end of the second air suction pipe 520. The fan provides stable power for the air suction process, ensuring that the air suction work is stable and continuous. The first air suction pipe 510 is arranged along the length direction of the cross beam 400 and has a plurality of air suction openings communicating with the cutting space, which can cover a large area of the cutting area and reduce the dust removal dead angle. The air suction box 530 connects the first air suction pipe 510 and the second air suction pipe 520 and can slide and communicate with the second air suction pipe 520, ensuring that the communication between the parts is not affected when the air suction assembly 500 moves with the cutting assembly 600, and adapting to different positions of the air suction demand.

[0029] In the process of moving the suction box 530 with the cutting assembly 600, the second suction pipe 520 and the suction box 530 can be interrupted in communication, causing the dust generated in the cutting area to not be timely sucked away. Thus, in an embodiment, the suction box 530 includes a box body 531, a pressing belt 532, two upper rollers 533, and two lower rollers 534. The box body 531 is provided with a first opening in communication with the first suction pipe 510 on the side surface, and a second opening on the bottom surface. The top of the second suction pipe 520 is provided with a third opening, and the two ends of the pressing belt 532 are fixedly connected to the two ends of the second suction pipe 520 and cover the third opening. The two upper rollers 533 are arranged at the two ends of the inner top of the box body 531, and the two lower rollers 534 are arranged at the two ends of the inner bottom of the box body 531. The pressing belt 532 passes the lower rollers 534 and the upper rollers 533 in sequence, so that the second opening and the third opening remain in a state of communication during movement. Through the arrangement of the pressing belt 532, the upper rollers 533, and the lower rollers 534, the second opening of the suction box 530 and the third opening of the second suction pipe 520 can remain in a state of communication during movement with the beam 400, even if there is relative displacement or the like. Dust can continuously and smoothly flow from the first suction pipe 510 to the second suction pipe 520 through the suction box 530, avoiding the influence of communication interruption on dust removal effect and ensuring stable dust removal work.

[0030] The pressing belt 532 can not be tightly attached between the pressing belt 532 and the second suction pipe 520 during movement, causing the sealing effect to decrease, and dust can leak from the gap. Thus, in an embodiment, the suction box 530 further includes at least two groups of pulleys 535. The two groups of pulleys 535 are arranged on the front side wall and the rear side wall of the box body 531 in the moving direction of the first guide rail 700, respectively. The wheel surface of the pulley 535 abuts against the outer surface of the pressing belt 532, so that the pressing belt 532 is tightly pressed on the top surface of the second suction pipe 520. By arranging the pulleys 535 on the front and rear side walls of the suction box 530, and abutting the wheel surface of the pulley 535 against the outer surface of the pressing belt 532, the pressing belt 532 can be more tightly pressed on the top surface of the second suction pipe 520, and the sealing effect is strengthened. The pulleys 535 assist in supporting and restraining the pressing belt 532, so that the pressing belt 532 can maintain appropriate tension and form during movement.

[0031] When the device has a long stroke, the operator cannot observe the problem in real time when the cutting is processed. Therefore, in an embodiment, the mobile dust removal device further comprises an operation platform, a fence and an observation window, the operation platform is fixed on one side of the dust collection chamber 200, the fence is arranged around the periphery of the operation platform; the observation window is arranged on the side wall of the dust collection chamber 200 close to the operation platform. By arranging the operation platform and the observation window, the operator can intuitively observe the working scene in the dust collection chamber 200, which is convenient for the operator to perform operations such as starting and stopping the cutting device, adjusting related parameters, etc., and bears the weight of the operator and places some necessary operating tools, etc.; the fence plays a role in protection and isolation, and guarantees the personal safety of the operator.

[0032] The gap between the bottom of the dust collection chamber 200 and the bed body 100 will become a channel for dust to escape. Therefore, in an embodiment, the dust collection chamber 200 further comprises a dust curtain 220, which is arranged at the bottom of the dust collection chamber 200 and circumferentially around the edge of the bottom of the dust collection chamber 200, and the lower end of the dust curtain 220 is in contact with the top surface of the bed body 100 to completely cover the cutting space, preventing dust from escaping from the bottom of the dust collection chamber 200. The dust curtain 220 can effectively fill the gap between the bottom of the dust collection chamber 200 and the bed body 100, completely wrap the cutting space, reduce the possibility of dust escaping from the bottom of the dust collection chamber 200, enable the air suction assembly to more efficiently suck away the dust generated by cutting, improve the overall dust removal effect, and maintain the cleanliness of the working environment. Specifically, the dust curtain and the dust collection chamber are detachably connected by magic tape or bolts.
