Description

Technical Field

[0001] The invention relates to the field of breaking hammers, and in particular to a rapid dust reduction device for breaking hammers. Background Art

[0002] A breaker is a kind of engineering machinery, mainly used to break hard materials such as rocks and concrete. It is driven by a hydraulic system, using the reciprocating motion of the piston to generate impact force, so that the end of the drill rod of the breaker produces high-frequency impact, thereby breaking objects. Breakers are widely used in mining, road construction, building demolition and other fields. They can efficiently complete the crushing operation, improve work efficiency and reduce manual labor intensity.

[0003] A breaker hammer breaks objects through mechanical vibration. This process will release the dust inside the object. Due to the effect of vibration, the dust will fly into the air and form dust. The dust will reduce the visibility of the breaker hammer and affect the operator's judgment, thereby reducing work efficiency. In addition, the dust will reduce the crushing efficiency of the breaker hammer, because the breaker hammer needs to consume more energy to break objects covered with dust. The dust may also increase the wear of mechanical parts and reduce the service life of the equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a rapid dust reduction device for a breaker hammer.

[0005] The present invention provides a rapid dust reduction device for a breaker hammer, comprising a breaker hammer, the top of which is mounted on a vehicle body through a mounting frame, and further comprising:

[0006] A water tank is fixedly mounted on the vehicle body, and the bottom of the side wall of the water tank is fixedly connected to an exhaust port;

[0007] A fixing frame, fixed to the bottom of the mounting frame;

[0008] A threaded sleeve, which is arranged on the outer ring of the fixing frame;

[0009] A dust cover is installed on the outer ring of the threaded sleeve and is used to isolate the working area of ​​the breaker to reduce the spread of dust;

[0010] A dust suppression assembly is installed between the mounting frame and the dust cover, and is used to discharge the dust inside the dust cover through airflow, and discharge the airflow after separating the dust from the water inside the water tank;

[0011] When the breaker is working, the dust cover covers the working area of ​​the breaker. The dust generated by the Shudie breaker can be isolated in the covering space formed by the dust cover, so that the dust is controlled in the local space, which is helpful to avoid the situation where the dust spreads in large quantities and causes obstruction.

[0012] The water tank stores water inside, which is pumped out under the action of the dust suppression component, and the dust inside the space covered by the dust cover is separated and processed in cooperation with the action of the airflow, so that the airflow is then discharged normally, and the dust remains in the water tank and is collected. On the one hand, it avoids the situation where the dust is difficult to be controlled in the local space after being generated in large quantities inside the dust cover, thus causing overflow. On the other hand, by collecting the dust inside the water tank, it is beneficial to avoid the situation where the dust settles on the ground and then dries and is then raised again with the operation of the breaker, which is beneficial to achieve rapid dust reduction around the breaker, and the dust inside the dust cover is pumped out by the dust suppression component for dust suppression treatment, which can quickly discharge the dust inside the dust cover, so that the field of view inside the transparent dust cover has a certain clarity, thereby facilitating the operation of the staff.

[0013] Preferably, the dust cover comprises:

[0014] The spiral rack is arranged in a spiral shape, and the outer rings fall down in sequence;

[0015] The isolation cloth is fixed between each circle of the spiral frame, and covers the outer circle of the spiral frame to form a protective space after it falls down;

[0016] The setting of the spiral frame facilitates the storage of the dust cover as a whole. When the bottom of the spiral frame loses support, the bottom of the spiral frame hangs down to form a covering space. The isolation cloth is made of transparent material, so that the outside world can view the position of the internal breaker, which is convenient for operation. The covering space formed by the isolation cloth and the spiral frame is a space with adaptable shape, which is conducive to avoiding the dust cover from being damaged by the breaker during vibration operation.

[0017] Preferably, the dust cover further comprises:

[0018] The spiral frame is composed of a plurality of curved short rods connected in sequence, and adjacent curved short rods are hinged to each other;

[0019] A spiral frame is formed by a number of curved short rods hinged to each other in sequence. When a certain position at the bottom is obstructed by broken stones or concrete blocks, the curved short rod corresponding to this position can be lifted upward, and the two adjacent curved short rods can continue to hang downward through the hinged connection, which helps to avoid the situation where one corner of the dust cover is lifted upward when there is obstruction from broken stones or concrete blocks, causing dust to seep out and affecting the dust covering effect.

[0020] Preferably, the dust cover further comprises:

[0021] A plurality of magnets are respectively fixed on the outer wall of the spiral frame of each circle, and the magnets of each circle are divided into a plurality of groups aligned and matched with each other, and the matched magnets have different magnetic poles that repel each other;

[0022] The mutual repulsion between adjacent magnets can push the outer spiral frame to fall downward in sequence, so that the spiral frame can be promoted to form a nearly spherical covering space through the promotion of magnetic force, so as to facilitate the deployment of the dust cover. The magnet here can be an electromagnet, which is energized to generate magnetism to promote the deployment of the dust cover when in use, and the circuit is disconnected when storing so that the dust cover can be freely stored to reduce the occupied space.

[0023] Preferably, the dust suppression assembly comprises:

[0024] A dust suppression box is fixed on the side wall of the mounting frame;

[0025] An installation cylinder fixedly connected to the top of the dust suppression box;

[0026] A driving fan is arranged inside the mounting tube;

[0027] An output hose is fixedly connected between the dust suppression box and the water tank, and one end connected to the water tank is located below the water surface;

[0028] A spray assembly, installed inside the dust reduction box, used to spray the water inside the water tank into the dust reduction box, and located below the driving fan;

[0029] A dust collecting pipe connected between the dust reduction box and the dust cover, and one end connected to the dust reduction box is located above the driving fan;

[0030] A driving assembly, mounted on the top of the dust reduction box, for driving the driving fan to rotate;

[0031] After the driving component is started, the driving fan is driven to rotate rapidly. After the driving fan rotates, it drives the airflow to flow, so that the airflow flows along the outside to the inside of the dust cover, and then flows along the trajectory of the dust cover and the dust collecting pipe, the installation tube, the dust reduction box, the output hose, and the water tank, thereby driving the dust into the dust reduction box. When the dust enters the dust reduction box, it is sprayed by the spray component, so that the dust driven by the airflow settles to the inside of the dust reduction box. Then the airflow enters the inside of the dust reduction box and is discharged from the exhaust port, so that a large amount of fine water mist passes through the small dust reduction box space, which is conducive to concentrated dust sedimentation, so that there is no need to spray water mist on a large scale around the breaker, which is conducive to reducing the waste of water resources, and spraying water mist in the dust reduction box to settle the dust, so that the settled dust falls into the inside of the dust reduction box, and then when the water level inside the dust reduction box rises to the height of the output hose, it flows to the inside of the water tank along with the output hose, which is conducive to avoiding the situation where when the dust settles on the road surface, it is quickly dried in hot and windy weather and is raised again, resulting in low dust reduction efficiency.

[0032] Preferably, the drive assembly comprises:

[0033] A connecting box is fixed above the dust reduction box and is connected to the dust reduction box;

[0034] A motor, fixed to the top of the connecting box;

[0035] A telescopic rod is rotatably mounted inside the dust reduction box, a telescopic end of which is fixedly connected to the output shaft of the motor, and a fixed end of which is connected to the driving fan;

[0036] After the motor is started, the output shaft drives the telescopic rod connected thereto to rotate, and the rotation of the telescopic rod drives the driving fan to rotate, thereby realizing the rotation driving of the driving fan.

[0037] Preferably, the dust suppression assembly further comprises:

[0038] A cylinder, fixed to the top of the connecting box;

[0039] A sealing cylinder is fixedly connected to the top of the installation cylinder, and the top is connected to the connecting box, and the dust collecting pipe is connected to the connecting box;

[0040] A sealing plate is slidably mounted between the connecting box and the interior of the sealing cylinder, the end of the telescopic rod of the cylinder is connected to the sealing plate, and the sealing plate is fixedly connected to the fixed end of the telescopic rod;

[0041] When the sealing plate moves downward to the interior of the sealing cylinder, the sealing plate isolates the sealing cylinder from the dust collecting pipe;

[0042] After the cylinder is started, the sealing plate is driven to move through the telescopic rod. When the sealing plate moves to the inside of the connecting box, it is located above the dust collecting pipe. The dust collecting pipe connected to the connecting box will not be blocked, so that the airflow can flow smoothly through the dust collecting pipe, the connecting box and the sealing cylinder. When the sealing plate moves to the inside of the sealing cylinder, it blocks the sealing cylinder and the connecting box, so that the airflow cannot flow to the inside of the sealing cylinder to seal the sealing cylinder. At this time, the sealing plate drives the driving fan to be immersed below the water surface through the telescopic rod. At this time, the driving assembly drives the driving fan to rotate slowly, so as to clean the dust on the driving fan. After cleaning, the driving fan is driven to reset and resume work, which is beneficial to avoid the accumulation of dust on the driving fan, causing blockage and affecting the flow of air.

[0043] Preferably, the dust suppression assembly further comprises:

[0044] The cylinder, the sealing cylinder, the sealing plate, the mounting cylinder, the driving fan, and the driving assembly are all provided with two and symmetrically arranged, and the two driving fans are alternately moved downward for cleaning;

[0045] The cylinder and the sealing cylinder, the sealing plate, the mounting cylinder, the drive fan, and the drive assembly are each provided with two and are symmetrically arranged, so that when one sealing cylinder is blocked to clean the drive fan, the other drive fan can work normally, which is beneficial to maintain continuous drive of the airflow to continuously separate and clean the dust, thereby helping to avoid the interruption of dust treatment caused by cleaning of the drive fan.

[0046] Preferably, the spray assembly comprises:

[0047] A circular box is fixed on the side wall of the dust reduction box and extends through the inside of the dust reduction box;

[0048] A plurality of atomizing nozzles are respectively fixedly mounted on the side walls of the circular box;

[0049] A water delivery pipe, fixedly connected between the circular box and the water tank;

[0050] A water pump, fixed inside the water tank, with an output end connected to the water pipe;

[0051] A filter plate, fixed inside the water tank and located above the water pump;

[0052] After the water pump is started, it drives the water flow, and the water flows along the water pipe into the circular box, and then is sprayed out by the atomizing nozzle, so that the water mist settles the dust in the air flow. The setting of the filter plate allows the separated dust to accumulate in the space above the filter plate, preventing the dust from entering the interior of the water pump and causing damage.

[0053] Preferably, the dust suppression assembly further comprises:

[0054] A V-shaped filter frame fixed inside the water tank;

[0055] A plurality of arc-shaped porous plates are fixed in sequence between the V-shaped filter frame and the filter plate;

[0056] The V-shaped filter frame is set so that after the airflow is output from the output hose into the water, it can prolong the time in the water under the blocking effect of the V-shaped filter frame, so as to increase the amount of dust incorporated into the water, and when a large amount of dust accumulates in the water, the airflow can flow along the trajectory of the V-shaped filter frame to the sharp corner position for discharge, and it can also avoid the situation that the airflow is blocked at the position below the V-shaped filter frame and the internal air pressure is too high;

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] The present invention controls the dust within a local space by arranging a dust suppression component and a dust cover, thereby helping to avoid the obstruction caused by the large-scale diffusion of dust. The dust inside the dust cover is extracted by the dust suppression component for dust suppression treatment, and the dust inside the dust cover can be quickly discharged, so that the field of view inside the transparent dust cover has a certain clarity, thereby facilitating the operation of the staff.

DETAILED DESCRIPTION

[0067] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0068] like Figures 1 to 7 The rapid dust reduction device for a breaker hammer shown in the figure comprises a breaker hammer 1, the top of which is mounted on a vehicle body through a mounting frame 101, and further comprises:

[0069] The water tank 102 is fixedly mounted on the vehicle body, and the bottom of the side wall of the water tank 102 is fixedly connected to an exhaust port 105;

[0070] A fixing frame 103, fixed to the bottom of the mounting frame 101;

[0071] A threaded sleeve 104, which is disposed on the outer ring of the fixing frame 103;

[0072] A dust cover is installed on the outer ring of the threaded sleeve 104 and is used to isolate the working area of ​​the breaker 1 to reduce the spread of dust;

[0073] The dust suppression assembly is installed between the mounting frame 101 and the dust cover, and is used to discharge the dust inside the dust cover through the airflow, and discharge the airflow after separating the dust from the water 405 inside the water tank 102;

[0074] The breaker hammer breaks objects through mechanical vibration. This process will release the dust inside the object. Due to the vibration, the dust will fly into the air and form dust. The dust will reduce the visibility of the breaker hammer and affect the judgment of the operator, thereby reducing work efficiency. In addition, the dust will reduce the crushing efficiency of the breaker hammer because the breaker hammer needs to consume more energy to break the objects covered by dust. The dust may also increase the wear of mechanical parts and reduce the service life of the equipment.

[0075] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: during the operation of the breaker 1, the working area of ​​the breaker 1 is covered by a dust cover, and the dust generated by the Shudie breaker 1 during operation can be isolated in the covering space formed by the dust cover, so that the dust is controlled in the local space, which is conducive to avoiding the occurrence of obstruction caused by the large-scale diffusion of dust;

[0076] Water 405 is stored inside the water tank 102. The water 405 is pumped out under the action of the dust suppression component, and the dust inside the space covered by the dust cover is separated and processed in cooperation with the action of the airflow, so that the airflow is then discharged normally, and the dust remains in the water tank 102 and is collected. On the one hand, it can prevent the dust from being difficult to control in the local space after being generated in large quantities inside the dust cover, thereby causing overflow. On the other hand, by collecting the dust inside the water tank 102, it is beneficial to prevent the dust from settling on the ground and then drying and then being raised again with the operation of the breaker 1, which is beneficial to achieve rapid dust reduction around the breaker 1, and the dust inside the dust cover is pumped out by the dust suppression component for dust suppression treatment, which can quickly discharge the dust inside the dust cover, so that the field of view inside the transparent dust cover has a certain clarity, thereby facilitating the operation of the staff.

[0077] As an optional embodiment, the dust cover includes:

[0078] The spiral frame 2 is arranged in a spiral shape, and the outer rings fall downward in sequence;

[0079] The isolation cloth 201 is fixed between each circle of the spiral frame 2, and covers the outer circle of the spiral frame 2 to form a protective space;

[0080] The setting of the spiral frame 2 facilitates the storage of the dust cover as a whole. When the bottom of the spiral frame 2 loses support, the bottom of the spiral frame 2 hangs down to form a covering space. The isolation cloth 201 is made of transparent material, so that the outside world can view the position of the breaker 1 inside, which is convenient for operation. The covering space formed by the isolation cloth 201 and the spiral frame 2 is a space with an adaptable shape, which is beneficial to avoid the dust cover being damaged by the impact during the vibration operation of the breaker 1.

[0081] As an optional embodiment, the dust cover further includes:

[0082] The spiral frame 2 is composed of a number of curved short rods connected in sequence, and adjacent curved short rods are hinged to each other;

[0083] The spiral frame 2 formed by a plurality of curved short rods hinged to each other in sequence can lift up when a certain position at the bottom is blocked by broken stones or concrete blocks, while the two adjacent curved short rods can continue to hang down through the hinged connection, thereby helping to avoid the situation where one corner of the dust cover is lifted up when there is obstruction from broken stones or concrete blocks, causing dust to seep out and affecting the dust covering effect.

[0084] As an optional embodiment, the dust cover further includes:

[0085] A plurality of magnets 3 are fixed on the outer wall of each circle of the spiral frame 2, and the magnets 3 of each circle are divided into a plurality of groups aligned and matched with each other, and the matched magnets 3 have different magnetic poles that repel each other;

[0086] The mutual repulsion between adjacent magnets 3 can push the outer spiral frame 2 to fall downward in sequence, so that the spiral frame 2 can be promoted to form a nearly spherical covering space through the promotion of magnetic force, so as to facilitate the deployment of the dust cover. The magnet 3 here can be an electromagnet, which is energized to generate magnetism to promote the deployment of the dust cover when in use, and the circuit is disconnected when stored so that the dust cover can be freely stored to reduce the occupied space.

[0087] As an optional embodiment, the dust suppression assembly includes:

[0088] The dust suppression box 4 is fixed on the side wall of the mounting frame 101;

[0089] The installation tube 401 is fixedly connected to the top of the dust suppression box 4;

[0090] The driving fan 402 is arranged inside the mounting tube 401;

[0091] The output hose 403 is fixedly connected between the dust suppression box 4 and the water tank 102, and one end connected to the water tank 102 is located below the surface of the water 405;

[0092] A spray assembly is installed inside the dust reduction box 4, used to spray the water 405 inside the water tank 102 into the dust reduction box 4, and is located below the driving fan 402;

[0093] The dust collecting pipe 406 is connected between the dust reduction box 4 and the dust cover, and one end connected to the dust reduction box 4 is located above the driving fan 402;

[0094] A driving assembly, mounted on the top of the dust reduction box 4, for driving the driving fan 402 to rotate;

[0095] After the driving component is started, the driving fan 402 is driven to rotate rapidly. After the driving fan 402 rotates, it drives the air flow to flow, so that the air flow follows the outside to the inside of the dust cover, and then flows along the trajectory of the dust cover and the dust collecting pipe 406, the installation cylinder 401, the dust reduction box 4, the output hose 403, and the water tank 102, thereby driving the dust into the inside of the dust reduction box 4. When the dust enters the inside of the dust reduction box 4, it is sprayed by the spray component, so that the dust driven by the air flow settles to the inside of the dust reduction box 4. Then the air flow enters the inside of the dust reduction box 4 and is discharged from the exhaust port 105, thereby passing through the small dust reduction box 4. A large amount of fine water mist is used inside the space to concentrate the dust sedimentation, so there is no need to spray water mist in a large range around the breaker 1, which is helpful to reduce the waste of water resources. In addition, water mist is sprayed in the dust reduction box 4 to settle the dust, so that the settled dust falls into the dust reduction box 4. Then, when the water level inside the dust reduction box 4 rises to the height of the output hose 403, it flows to the inside of the water tank 102 along with the output hose 403, which is helpful to avoid the dust settling on the road surface and quickly drying up in hot and windy weather, causing it to be lifted up again, resulting in low dust reduction efficiency.

[0096] As an optional embodiment, the driving component includes:

[0097] The connecting box 5 is fixed above the dust reduction box 4 and is connected with the dust reduction box 4;

[0098] The motor 501 is fixed on the top of the connecting box 5;

[0099] The telescopic rod 502 is rotatably mounted inside the dust suppression box 4, the telescopic end is fixedly connected to the output shaft of the motor 501, and the fixed end is connected to the driving fan 402;

[0100] After the motor 501 is started, the output shaft drives the telescopic rod 502 connected thereto to rotate. After the telescopic rod 502 rotates, the driving fan 402 is driven to rotate, thereby realizing the rotation drive of the driving fan 402.

[0101] As an optional embodiment, the dust suppression assembly further includes:

[0102] The cylinder 6 is fixed to the top of the connecting box 5;

[0103] The sealing cylinder 602 is fixedly connected to the top of the installation cylinder 401, and the top is connected to the connecting box 5, and the dust collecting pipe 406 is connected to the connecting box 5;

[0104] The sealing plate 601 is slidably installed between the connecting box 5 and the inside of the sealing cylinder 602. The end of the telescopic rod of the cylinder 6 is connected to the sealing plate 601, and the sealing plate 601 is fixedly connected to the fixed end of the telescopic rod 502;

[0105] When the sealing plate 601 moves downward to the inside of the sealing cylinder 602, the sealing plate 601 isolates the sealing cylinder 602 from the dust collecting pipe 406;

[0106] After the cylinder 6 is started, the sealing plate 601 is driven to move through the telescopic rod. When the sealing plate 601 moves to the inside of the connecting box 5, it is located above the dust collecting pipe 406. The dust collecting pipe 406 connected to the connecting box 5 will not be blocked, so that the airflow can flow smoothly through the dust collecting pipe 406, the connecting box 5, and the sealing cylinder 602. When the sealing plate 601 moves to the inside of the sealing cylinder 602, the sealing cylinder 602 and the connecting box 5 are blocked, so that the airflow cannot flow to the inside of the sealing cylinder 602 to seal the sealing cylinder 602. At this time, the sealing plate 601 drives the driving fan 402 to be immersed below the water surface through the telescopic rod 502. At this time, the driving assembly drives the driving fan 402 to rotate slowly, so as to clean the dust on the driving fan 402. After cleaning, the driving fan 402 is driven to reset and resume work, which is conducive to avoiding the accumulation of a large amount of dust on the driving fan 402 to cause blockage and affect the flow of air.

[0107] As an optional embodiment, the dust suppression assembly further includes:

[0108] The cylinder 6, the sealing cylinder 602, the sealing plate 601, the mounting cylinder 401, the driving fan 402, and the driving assembly are all provided with two and symmetrically arranged, and the two driving fans 402 are alternately moved downward for cleaning;

[0109] The cylinder 6 and the sealing cylinder 602, the sealing plate 601, the mounting cylinder 401, the driving fan 402, and the driving assembly are all provided with two and are symmetrically arranged, so that when one sealing cylinder 602 is blocked to clean the driving fan 402, the other driving fan 402 can work normally, which is beneficial to maintain continuous drive of the airflow to continuously separate and clean the dust, thereby helping to avoid the interruption of dust treatment caused by the cleaning of the driving fan 402.

[0110] As an optional embodiment, the spray assembly includes:

[0111] The circular box 7 is fixed on the side wall of the dust reduction box 4 and extends through the inside of the dust reduction box 4;

[0112] A plurality of atomizing nozzles 701 are respectively fixedly mounted on the side walls of the circular box 7;

[0113] The water delivery pipe 702 is fixedly connected between the circular box 7 and the water tank 102;

[0114] The water pump 703 is fixed inside the water tank 102, and the output end is connected to the water pipe 702;

[0115] The filter plate 704 is fixed inside the water tank 102 and is located above the water pump 703;

[0116] After the water pump 703 is started, it drives the water flow, and the water flow enters the circular box 7 along the water pipe 702, and is then sprayed out by the atomizing nozzle 701, so that the water mist settles the dust in the air flow by atomizing and spraying the water flow. The setting of the filter plate 704 allows the separated dust to accumulate in the space above the filter plate 704, thereby preventing the dust from entering the interior of the water pump 703 and causing damage.

[0117] As an optional embodiment, the dust suppression assembly further includes:

[0118] V-shaped filter frame 404, fixed inside the water tank 102;

[0119] A plurality of arc-shaped porous plates 8 are fixed in sequence between the V-shaped filter frame 404 and the filter plate 704;

[0120] The V-shaped filter frame 404 is provided so that after the airflow is output from the output hose 403 to the water 405, the time in the water 405 can be prolonged under the blocking effect of the V-shaped filter frame 404, so as to increase the amount of dust incorporated into the water 405. When a large amount of dust accumulates in the water 405, the airflow can flow along the trajectory of the V-shaped filter frame 404 to the sharp corner position for discharge, and the airflow can be prevented from being blocked at a position below the V-shaped filter frame 404, causing the internal air pressure to be too high.

[0121] The arrangement of multiple groups of arc-shaped porous plates 8 can disperse the exhausted airflow multiple times. The arc-shaped porous plates 8 are porous plates with circular holes of larger diameter. The airflow is dispersed multiple times by the arrangement of multiple arc-shaped porous plates 8, which helps to disperse the airflow into a number of small bubbles, thereby increasing the contact between dust in the airflow and water 405, and helps to promote the small particles of dust remaining in the airflow to be integrated into the water 405 for separation.

[0122] Working principle of the present invention: During the operation of the breaker 1, the working area of ​​the breaker 1 is covered by the dust cover, and the dust generated by the Shudie breaker 1 during operation can be isolated in the covering space formed by the dust cover, so that the dust is controlled in the local space, which is conducive to avoiding the occurrence of obstruction caused by the large-scale diffusion of dust;

[0123] Water 405 is stored inside the water tank 102. The water 405 is pumped out under the action of the dust suppression component, and the dust inside the space covered by the dust cover is separated and processed in cooperation with the action of the airflow, so that the airflow is then discharged normally, and the dust remains in the water tank 102 and is collected. On the one hand, it can prevent the dust from being difficult to control in the local space after being generated in large quantities inside the dust cover, thereby causing overflow. On the other hand, by collecting the dust inside the water tank 102, it is beneficial to prevent the dust from settling on the ground and then drying and then being raised again with the operation of the breaker 1, which is beneficial to achieve rapid dust reduction around the breaker 1, and the dust inside the dust cover is pumped out by the dust suppression component for dust suppression treatment, which can quickly discharge the dust inside the dust cover, so that the field of view inside the transparent dust cover has a certain clarity, thereby facilitating the operation of the staff.
