Description

Technical Field

[0001] The invention relates to the technical field of dust removal in road construction, and in particular to a dust removal device for road construction and a use method thereof. Background Art

[0002] Dust removal in road construction is an important part of ensuring construction quality and environmental quality. During the road construction process, a large amount of dust will be generated, which not only affects the air quality, but may also pose a threat to human health. Therefore, it is very important to take effective dust removal measures. Common dust removal methods include using sprinkler trucks to regularly spray water to reduce dust, setting up dust-proof nets to intercept floating dust, and using fog cannons and other equipment to spray dust. These measures can significantly reduce the dust concentration at the construction site, improve air quality, and protect the health of construction workers. At the same time, it also helps to improve the overall image of the project.

[0003] When removing dust during road construction, water spraying is usually used to form water mist to reduce dust.

[0004] The existing patent (publication number: CN202222705169.X) discloses a municipal road dust removal device, including a dust box, a dust storage box is fixedly installed at the bottom of the dust box, and a suction fan for dust collection is fixedly installed on one side of the dust box, and a filter for filtering dust is installed inside the dust box; a drive motor is fixedly installed inside the dust box, a threaded rod is fixedly connected to the bottom end of the rotating shaft of the drive motor, and a mobile box is threadedly connected to the outer wall of the threaded rod, and a micro motor is fixedly installed on the top of one side of the mobile box. During the use of the above equipment, since the road construction is usually carried out outdoors, although there are fences on both sides, it will still be affected by the natural environment such as wind speed. When the wind is too strong, the road dust will be rolled up and scattered in the air to increase the spread range. At this time, the dust removal equipment has a poor dust reduction effect on a large range of dust, resulting in poor dust removal effect.

[0015] A method for using a dust removal device for road construction comprises the following steps:

[0016] S1. The mounting base is clamped on the enclosure to be installed through the enclosure slot, and the fixing bolts are tightened to tighten the connection to keep it fixed. Water is input into the nozzle connection tube through the input pipe and dispersed to multiple spray pipes for atomization and output of water mist;

[0017] S2. When wind blows on both sides of the device, the side of the rotating blade extending out of the windshield will be affected by the wind and rotate, driving the fan shaft at the bottom to rotate and drive the follower mechanism to work;

[0018] S3, the rotating blade drives the input crank to rotate, and the input crank drives the driving gear through the toggle column at one end, passes the dead point and makes the input crank and the driving gear turn in the same direction in the first half of the circle. When the other end of the input crank is in the first half of the circle, it approaches and pushes the output crank through the linkage rod to drive the driving gear to rotate, and does not pass the dead point position during rotation. When the input crank rotates in the second half of the circle, it moves away from the output crank through the linkage rod to pull it back. At this time, the driving gear reverses and drives the output shaft to reverse forward and reverse by meshing with the driven gear. When the device is affected by the wind on the side, it will drive the angle mechanism to swing back and forth on the side where the wind blows, so that the water mist generated by the nozzle is aimed at the direction of the wind, thereby reducing the dust blown up by the wind;

[0019] S4. The output shaft drives the swinging mounting shell to swing back and forth on the sliding groove. When the path is arc-shaped and on both sides, the fixed pipe sleeve and the articulated pipe sleeve can be raised around the hinge to increase the spray range of the spray pipe. Since the moving cam can slide back and forth on the mounting sleeve, it will be constrained by the pulling rope to move backward on the mounting sleeve when swinging to both sides. The rotating contact column contacts the rotating cam groove on the mounting sleeve. The moving cam will also rotate when moving. The linear block is pushed outward by the linear cam groove when the moving cam rotates, and the internal spray pipe is pulled by the articulated rod to tilt the spray pipe. At this time, the spray range will be larger. When the mounting sleeve swings back to the middle position, the moving cam is no longer affected by the pulling rope and moves forward on the mounting sleeve under the action of centrifugal force. When the side of the device is affected by wind, the nozzle will be swung to the windward side and the spray range will be increased to enhance the dust reduction effect.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, through the joint action of the wind-catching mechanism and the follow-up mechanism, when wind blows on both sides of the device, the wind force will drive the rotating blades to rotate and drive the follow-up mechanism at the bottom to work, and the follow-up mechanism converts the rotation into reciprocating swinging, and the swinging direction is toward the direction of the wind, so that when the device is affected by the wind on the side, it will drive the nozzle to swing back and forth on the side where the wind blows, so that the water mist generated by the nozzle is aimed in the direction of the wind, thereby reducing the dust blown up by the wind.

[0022] In the present invention, through the arrangement of the follower mechanism and the angle mechanism, the output shaft drives the swing mounting housing to swing back and forth on the sliding groove. When the path is arc-shaped and on both sides, the fixed pipe sleeve and the hinged pipe sleeve can be raised around the hinge to increase the spray range of the spray pipe.

[0023] In the present invention, through the arrangement of the angle mechanism and the range mechanism, since the movable cam can slide back and forth on the mounting sleeve, it will be constrained by the pulling rope to move backward on the mounting sleeve when swinging to both sides, and the linear block is pushed outward in the linear cam groove to pull the internal spray pipe, so that the spray pipe is tilted. At this time, the spray range will be larger, and when the side of the device is affected by the wind, the nozzle will be swung to the windward side and the spray range will be increased to enhance the dust reduction effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 11 The present invention provides a technical solution: a dust removal device for road construction and a method of using the same, comprising a mounting base 1, an outer surface of the mounting base 1 is provided with an enclosure slot 11, an inner surface of the enclosure slot 11 is threadedly connected with a fastening bolt 12, an outer surface of the mounting base 1 is provided with an input pipe 2, one end of the input pipe 2 is fixedly connected with a nozzle connecting tube 23, one end of the nozzle connecting tube 23 is fixedly connected with a nozzle receiving tube 24, a top surface of the mounting base 1 is fixedly connected with a top mounting box 3, a top surface of the top mounting box 3 is provided with a wind catching mechanism 4, an inner surface of the top mounting box 3 is provided with a follower mechanism 5, a bottom surface of the top mounting box 3 is provided with an angle mechanism 6, and a range mechanism 7 is provided at one end of the angle mechanism 6, the mounting base 1 is clamped on the enclosure to be installed through the enclosure slot 11, the connection is tightened by the fastening bolt 12 to maintain a fixed state, water is received through the input pipe 2 and input into the nozzle connecting tube 23 and dispersed to multiple spray pipes 77 for atomizing and outputting water mist.

[0038] The wind catching mechanism 4 includes a wind shield plate 41, which is fixedly connected to the top surface of the top mounting box 3, and the top surface of the top mounting box 3 is rotatably connected to a rotating blade 42, and the bottom surface of the rotating blade 42 is fixedly connected to a fan blade shaft 421. When wind blows on both sides of the device, a large amount of dust will be lifted up. At this time, the side of the rotating blade 42 extending out of the wind shield plate 41 will be affected by the wind and rotate, and drive the fan blade shaft 421 at the bottom to rotate and drive the follower mechanism 5 to work.

[0039] The fan blade rotating shaft 421 penetrates the inner surface of the top installation box 3 and is rotationally connected to the inner wall thereof, and the follower mechanism 5 inside the top installation box 3 is driven to work by the fan blade rotating shaft 421 .

[0040] The follower mechanism 5 includes an input crank 51, the inner surface of the top mounting box 3 is rotatably connected with the input crank 51, one end of the input crank 51 is fixedly connected with a toggle column 511, the inner surface of the top mounting box 3 is provided with a toggle displacement groove 5111, the inner surface of the top mounting box 3 is provided with a gear mounting groove 5112, the end of the input crank 51 away from the toggle column 511 is rotatably connected with a linkage rod 52, the other end of the linkage rod 52 is rotatably connected with an output crank 53, the bottom surface of the output crank 53 is fixedly connected with a driving gear 54, the inner surface of the gear mounting groove 5112 is rotatably connected with a driven gear 55, and the bottom of the driven gear 55 The output shaft 551 is fixedly connected to the surface. Through the setting of the follower mechanism 5, during use, the rotating blade 42 drives the input crank 51 to rotate. In the initial state, the toggle column 511 is close to one side of the driving gear 54, and the input crank 51 and the linkage rod 52 are in line. When the input crank 51 starts to rotate, one end of the input crank 51 toggles the driving gear 54 through the toggle column 511, passes the dead point and makes the input crank 51 and the driving gear 54 turn in the same direction. At this time, the input crank 51, the linkage rod 52 and the output crank 53 are equivalent to a parallel double rocker mechanism. The input crank 51 pushes the linkage rod 52 to make the output crank 53 drive the driving gear 54. The input crank 51 rotates synchronously and has the same direction in the first half circle. After the input crank 51 rotates the first half circle, the input crank 51 and the linkage rod 52 are in the same line, but the linkage rod 52 and the output crank 53 are not in the same line. The input crank 51 continues to rotate and the linkage rod 52 moves away from the output crank 53 and pulls it back. At this time, the driving gear 54 reverses, realizing the effect of converting the transport rotation of the input crank 51 into the periodic forward and reverse rotation of the driving gear 54. The driving gear 54 is meshed with the driven gear 55. The driving gear 54 and the driven gear 55 have opposite directions and the transmission ratio is two to one. The periodic forward and reverse rotation of the driving gear 54 by half a circle drives the driven gear 55 to periodically reverse by a quarter of a circle. In one circle, the direction of the input crank 51 is determined by the wind blowing the rotating blade 42. After the driving gear 54 is meshed with the driven gear 55, the input crank 51 and the driven gear 55 turn in opposite directions. When the input crank 51 rotates in the first half circle, the driven gear 55 rotates in the direction of the wind, and in the second half circle, it reverses and resets to the initial position. The driven gear 55 drives the angle mechanism 6 to swing through the output shaft 551, so that when the device is affected by the wind on the side, it will drive the angle mechanism 6 to swing back and forth on the side where the wind blows, so that the water mist generated by the nozzle is aimed in the direction of the wind, thereby reducing the dust blown up by the wind.

[0041] The toggle column 511 is slidingly connected to the inner surface of the toggle displacement groove 5111, the input crank 51 is fixedly connected to the bottom surface of the fan blade shaft 421, the driving gear 54 is rotationally connected to the inner surface of the gear mounting groove 5112, the driving gear 54 is meshed with the driven gear 55, and the gear number ratio of the driving gear 54 and the driven gear 55 is one to two. The output shaft 551 penetrates the bottom surface of the top mounting box 3 and is rotationally connected to its inner wall. The toggle column 511 drives the driven gear 55 and only displaces in the toggle displacement groove 5111 without affecting other components. The gear mounting groove 5112 is used to install the driving gear 54 and the driven gear 55 and provide a rotation space. The driving gear 54 and the driven gear 55 will reverse the direction and use the transmission ratio to convert a half-turn swing into a quarter-turn swing.

[0042] The angle mechanism 6 includes a fixed bottom cylinder 61, which is fixedly connected to the bottom surface of the top mounting box 3, a sliding groove 611 is provided on the outer surface of the fixed bottom cylinder 61, and a swing mounting shell 62 is rotatably connected to the inner surface of the fixed bottom cylinder 61, and a fixed pipe sleeve 63 is fixedly connected to the outer surface of the swing mounting shell 62, and a fixed pipe groove 631 is provided on the inner surface of the fixed pipe sleeve 63, and a hinged pipe sleeve 64 is hingedly connected to the outer surface of the fixed pipe sleeve 63, and a hinged pipe groove 641 is provided on the inner surface of the hinged pipe sleeve 64. Through the setting of the angle mechanism 6, during use, the output shaft 551 drives the swingable mounting shell 62 to swing back and forth, and the swingable mounting shell 62 slides on the sliding groove 611. The sliding groove 611 is arc-shaped, with high sides and low middle. In this way, when the swingable mounting shell 62 swings to both sides, since the fixed pipe sleeve 63 and the articulated pipe sleeve 64 can rotate around the hinge, the articulated pipe sleeve 64 will be lifted to increase the spray range of the spray pipe 77. The fixed pipe sleeve 63 and the articulated pipe sleeve 64 are both provided with grooves for the pipe to pass through. The input pipe 2 enters the inside of the swingable mounting shell 62 from the input port 21, and is further output to the spray pipe 77 after passing through the fixed pipe sleeve 63 and the articulated pipe sleeve 64.

Through the setting of the range mechanism 7, during use, the mounting sleeve 71 will swing back and forth with the swing mounting shell 62 due to its connection with the hinged tube sleeve 64, and the moving cam 73 can slide back and forth on the mounting sleeve 71, but is constrained by the pulling mounting seat 74 through the pulling rope 741. When in the middle position, the two pulling ropes 741 are both in a taut state. When swinging to both sides, one side of the pulling rope 741 is pulled and the other side is compressed. The pulled side will The movable cam 73 is pulled to move backward on the mounting sleeve 71. Since the rotating contact column 731 on the mounting sleeve 71 contacts the rotating cam groove 712 on the mounting sleeve 71, the movable cam 73 will also rotate when moving, and the direct-acting block 75 can move in the groove of the limit bracket 711, and the outer side is sleeved on the direct-acting cam groove 732 of the movable cam 73. When the movable cam 73 rotates, the direct-acting cam groove 732 will drive the direct-acting block 75 to move. In this way, when the mounting sleeve 71 is at both sides, the direct-acting block 75 will move outward and pull the internal spray pipe 77 through the hinge rod 76, so that the spray pipe 77 is tilted, and the bottom of the spray pipe 77 is The nozzle connecting tube 23 is connected to the rotating seat 771, and the universal rotating seat 771 is fixedly connected to the top surface of the nozzle connecting tube 23, so that the spray pipe 77 can be rotated and tilted, and the water in the input pipe 2 will be input into the spray pipe 77 through the nozzle connecting tube 23 and sprayed out in atomization. When the spray pipe 77 is pulled by the direct-acting block 75, it will tilt, and the spray range will be larger at this time.

When the movable cam 73 rotates, the direct-acting cam groove 732 will push the direct-acting block 75, and the direct-acting block 75 will move outward and pull the internal spray pipe 77 through the hinge rod 76, so that the spray pipe 77 is tilted on the universal rotating seat 771, and the spray range will be larger at this time.

[0053] A method for using a dust removal device for road construction comprises the following steps:

[0054] S1. The mounting base 1 is clamped on the enclosure to be installed through the enclosure clamping slot 11, and the fastening bolts 12 are tightened to tighten the connection and keep it fixed. Water is input into the nozzle connection tube 23 through the input pipe 2 and dispersed to multiple spray pipes 77 for atomization and output of water mist;

[0055] S2. When wind blows on both sides of the device, the side of the rotating blade 42 extending out of the wind shield 41 will be affected by the wind and rotate, and drive the fan blade shaft 421 at the bottom to rotate and drive the follower mechanism 5 to work;

[0056] S3, the rotating blade 42 drives the input crank 51 to rotate, and the input crank 51 drives the driving gear 54 through the toggle column 511 at one end, passes the dead point and makes the input crank 51 and the driving gear 54 have the same direction in the first half circle. When the other end of the input crank 51 rotates in the first half circle, it approaches and pushes the output crank 53 through the linkage rod 52 to drive the driving gear 54 to rotate, and does not pass the dead point position during rotation. When the input crank 51 rotates in the second half circle, it moves away from the output crank 53 through the linkage rod 52 to pull back. At this time, the driving gear 54 reverses and drives the output shaft 551 to rotate forward and reversely by meshing with the driven gear 55. When the device is affected by the wind on the side, it will drive the angle mechanism 6 to swing back and forth on the side where the wind blows, so that the water mist generated by the nozzle is aimed at the direction of the wind, thereby reducing the dust blown up by the wind;

[0057] S4, the output shaft 551 drives the swing mounting housing 62 to swing back and forth on the sliding groove 611, and the path is arc-shaped and on both sides, the fixed pipe sleeve 63 and the hinged pipe sleeve 64 can be raised around the hinge to increase the spray range of the spray pipe 77, because the movable cam 73 can slide back and forth on the mounting sleeve 71, when it swings to both sides, it will be constrained by the pulling rope 741 to move backward on the mounting sleeve 71, and the rotating contact column 731 contacts the rotating cam groove 712 on the mounting sleeve 71, and the movable cam 73 moves at the same time. When the movable cam 73 rotates, the direct-acting block 75 is pushed outward by the direct-acting cam groove 732 and pulls the internal spray pipe 77 through the hinge rod 76, so that the spray pipe 77 is tilted. At this time, the spray range will be larger. When the mounting sleeve 71 swings back to the middle position, the movable cam 73 is no longer affected by the pulling rope 741 and moves forward on the mounting sleeve 71 under the action of centrifugal force. When the side of the device is affected by the wind, the nozzle will be swung to the windward side and the spray range will be increased to enhance the dust reduction effect.
