At present, road construction dust removal equipment is mainly used to remove dust, but traditional road construction dust removal equipment can only filter larger dust particles through the filter net, and cannot filter smaller dust particles, resulting in poor dust removal effect and inability to effectively remove dust in the air.

As the use time increased, the dust on the filter would increase, causing the filter to be blocked, affecting the filtering effect. Summary of the invention

[0005] The present invention aims to provide a dust removal device for road construction to solve the problem that the filter screen in the existing equipment is easily blocked.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a dust removal device for road construction, comprising a box body, wherein filtering mechanisms are symmetrically arranged on both sides of the box body, the filtering mechanism comprises a filter screen and a partition fixed to the box body, and an air outlet opened on the side wall of the box body, the filter screen is fixed to the partition, the spacing between the two filter screens is greater than the spacing between the two partitions, the filter screen is arc-shaped, and a through hole is arranged on the partition; a diverter plate is arranged between the two partitions, and the diverter plate is in an inverted V shape; an arc block is arranged between the two partitions, and a plurality of bristles for passing through the filter screen are arranged on the arc block; it also includes an introduction mechanism for introducing outside air into the position of the diverter plate in the box body, a power mechanism for driving the arc block to reciprocate in the two through holes, and a water spraying mechanism for spraying water on the two filter screens at the same time.

[0007] The principles and advantages of this solution are:

[0008] 1. This scheme introduces external air into the box through an introduction mechanism. The air acts on the diverter plate and is divided into two parts, which act on two filter nets respectively, so as to filter the dust and play a role in dust removal. The dust-removed air is discharged through the air outlet.

[0009] 2. During the air dust removal process, the power mechanism drives the arc block to reciprocate in the two through holes, and the arc block drives the bristles to move synchronously. The bristles are continuously moved in and out of the filter, so as to clean the filter and avoid clogging of the filter, thereby ensuring the filtering effect of dust, that is, the dust removal effect; and the arc block and the bristles can clean the two filters, which is highly practical.

[0010] 3. This solution can spray water on two filters through a water spray mechanism. The sprayed clean water can act on the air passing through the filter. On the one hand, it can clean the filter to avoid clogging of the filter and ensure the dust filtering effect; on the other hand, it can also perform dust reduction treatment on the air before passing through the filter to enhance the dust removal effect.

[0012] Through the above arrangement, the power unit drives the circular shaft to rotate, the circular shaft drives the cylindrical cam to rotate, the cylindrical cam drives the rack to vertically reciprocate through the curved groove and the auxiliary block, the rack engages with the gear to drive the gear to reciprocate, the gear drives the arc block and the bristles to swing back and forth through the rotating shaft and the swing arm, so that the arc block and the bristles reciprocate in the two through holes.

[0013] Furthermore, fixed plates are provided on the inner walls on both sides of the box body, side holes are provided on the partition plates, movable plates are slidably connected in the side holes, the fixed plates are located on the movement trajectory of the movable plates, and a C-shaped frame is provided between the two movable plates; a cam body is coaxially connected to the circular shaft, the cam body is abutted against both ends of the C-shaped frame, and the cam body can rotate in the C-shaped frame.

[0014] Through the above arrangement, during the rotation of the circular shaft, the circular shaft will also drive the cam body to rotate, and the cam body can drive the two movable plates to move back and forth horizontally through the C-shaped frame; when the two movable plates move to the left, the movable plate on the left is against the fixed plate on the left, and the gap between the movable plate on the right and the fixed plate on the right is the largest; when the two movable plates move to the right, the movable plate on the right is against the fixed plate on the right, and the gap between the movable plate on the left and the fixed plate on the left is the largest.

[0015] When the left movable plate abuts against the left fixed plate, the gap between the right movable plate and the right fixed plate is the largest, and the left movable plate and the left fixed plate are used to block the air, so that the air can enter the right side of the right partition through the gap between the right movable plate and the right fixed plate, and at this time, the arc block drives the bristles to swing to the left, and the bristles are used to clean the filter on the left; since no air enters, the cleaning effect on the filter is better; similarly, when the right movable plate abuts against the right fixed plate, the gap between the left movable plate and the left fixed plate is the largest, and the right movable plate and the right fixed plate are used to block the air, so that the air can enter the left side of the left partition through the gap between the left movable plate and the left fixed plate, and at this time, the arc block drives the bristles to swing to the right, and the bristles are used to clean the filter on the right; since no air enters, the cleaning effect on the filter is better.

[0017] Through the above arrangement, during the vertical reciprocating motion of the rack, the rack drives the piston block to reciprocate in the piston cylinder, so that the clean water in the water tank can be continuously introduced into the water outlet pipe through the water inlet pipe and the piston cylinder.

[0022] Furthermore, the introduction mechanism includes an air suction pump, an input pipe and an output pipe. The air suction pump is fixedly connected to the box body, and is connected to the output pipe and the output pipe respectively. One end of the output pipe away from the air suction pump extends into the box body, and the end of the output pipe away from the air suction pump is arranged toward the direction of the diverter plate.

[0023] Through the above arrangement, the air suction pump is started, and the external air is introduced into the box through the input pipe and the output pipe. After the air enters the box, it acts on the diverter plate.

[0024] Furthermore, discharge ports are provided on both sides of the box body, the discharge port is located below the air outlet, and a sealing block is detachably connected to the discharge port.

[0025] Through the above arrangement, when the dust removal work is carried out, the discharge port is sealed by the sealing block; when the dust removal work is completed, the sealing block is removed from the discharge port to discharge the mixture of water and dust.

[0041] The specific implementation process is as follows:

[0042] When in use, the suction pump 20 is started, and the outside air enters the box body 10 through the input pipe 21 and the output pipe 22. After the air enters the box body 10, it acts on the diverter plate 15, so that the air is divided into two parts and enters the left side of the left partition 12 and the right side of the right partition 12 respectively. The air passes through the filter net 11 to filter the dust, thereby playing a dust removal role. The dust-removed air is discharged through the outlet 13.

[0043] During dust removal, the filter 11 can also be cleaned, specifically: start the motor 31, the output shaft of the motor 31 drives the circular shaft to rotate, the circular shaft drives the cylindrical cam 34 to rotate, the cylindrical cam 34 drives the rack 37 to reciprocate vertically through the curved groove 35 and the auxiliary block 36, the rack 37 is engaged with the gear 33 to drive the gear 33 to reciprocate, the gear 33 drives the arc block 16 and the bristles 17 to swing back and forth through the rotating shaft and the swing arm 32, so that the arc block 16 and the bristles 17 reciprocate in the two through holes 14; during the reciprocating swing of the arc block 16 and the bristles 17, the bristles 17 are used to clean the left and right filter screens 11 to avoid clogging of the filter screen 11 and ensure the filtering effect of dust.

[0044] During the vertical reciprocating motion of the rack 37, the rack 37 drives the piston block 52 to reciprocate in the piston cylinder 51, so that the clean water in the water tank 50 can be continuously introduced into the water outlet pipe 54 through the water inlet pipe 53 and the piston cylinder 51. The clean water in the water outlet pipe 54 is divided into two parts and enters two branch pipes 55 respectively. The clean water in the branch pipe 55 is sprayed out to act on the filter screen 11. On the one hand, the filter screen 11 can be cleaned to avoid clogging of the filter screen 11, thereby ensuring the filtering effect of dust; on the other hand, the air before passing through the filter screen 11 can be subjected to dust reduction treatment to enhance the dust removal effect.

[0045] During the vertical reciprocating motion of the rack 37, the rack 37 will drive the linkage block to move synchronously, and the linkage block will drive the adjustment blocks 65 on the left and right sides to move synchronously; when the rack 37 moves downward, the linkage block will drive the adjustment block 65 to move downward as well, and the adjustment block 65 will also move horizontally along the path of the inclined groove 64 through the side block, so that the adjustment block 65 moves out of the side groove 63, that is, the two adjustment blocks 65 move away from each other; during the movement of the adjustment block 65 out of the side groove 63, the adjustment block 65 will squeeze the extrusion block 61 to move in the direction of the elastic layer 60, The first spring 62 is compressed; the adjustment block 65 continues to move, so that the elastic layer 60 is squeezed by the extrusion block 61 and deformed toward the inside of the shunt pipe 55, that is, the elastic layer 60 is concave, so that the clean water sprayed from the shunt pipe 55 can be pressurized, so that the clean water sprayed from the shunt pipe 55 has a longer range, so that the cleaning area of ​​the filter 11 can be expanded and the cleaning effect can be enhanced; and during the pressurization period, the contact position between the clean water sprayed from the water diversion pipe and the filter 11 is translated, so as to cover the filter 11 and clean the filter 11 more comprehensively. When the rack 37 moves upward, the linkage block drives the adjustment block 65 to move upward as well. The adjustment block 65 moves along the path of the inclined groove 64 through the side block and also moves horizontally, so that the adjustment block 65 moves into the side groove 63, that is, the two adjustment blocks 65 are close to each other, so that the squeezing effect of the adjustment block 65 on the squeezing block 61 disappears, so that the squeezing block 61 moves in the opposite direction under the action of the first spring 62, that is, the squeezing block 61 moves away from the elastic layer 60 and returns to the initial position.

[0046] During the movement of the extrusion block 61 toward the elastic layer 60, the extrusion block 61 drives the first wedge block 80 to move synchronously, so that the first wedge block 80 squeezes the second wedge block 81 to move upward, and the second spring 82 is compressed; during the upward movement of the second wedge block 81, the second wedge block 81 drives the wall block 83 to move upward, so that the wall block 83 blocks part of the port of the shunt pipe 55, so that the clean water sprayed from the shunt pipe 55 can be pressurized, so that the clean water sprayed from the shunt pipe 55 has a longer range, so that the cleaning area of ​​the filter screen 11 can be expanded and the cleaning effect can be enhanced. ; Moreover, during the pressurization period, the contact position between the clean water sprayed from the water distribution pipe and the filter screen 11 is translated, thereby covering the filter screen 11 and cleaning the filter screen 11 more comprehensively; during the movement of the extrusion block 61 in the direction away from the elastic layer 60, the extrusion block 61 drives the first wedge block 80 to move synchronously, so that the extrusion effect of the first wedge block 80 on the second wedge block 81 disappears, and the second wedge block 81 moves in the opposite direction under the action of the second spring 82, and the second wedge block 81 drives the wall block 83 to move synchronously, so that the shielding effect of the wall block 83 on the port of the diversion pipe 55 disappears.

[0047] During the rotation of the circular shaft, the circular shaft will also drive the cam body 43 to rotate, and the cam body 43 can drive the two movable plates 41 to move back and forth horizontally through the C-shaped frame 42; when the two movable plates 41 move to the left, the left movable plate 41 abuts against the left fixed plate 40, and the gap between the right movable plate 41 and the right fixed plate 40 is the largest; when the two movable plates 41 move to the right, the right movable plate 41 abuts against the right fixed plate 40, and the gap between the left movable plate 41 and the left fixed plate 40 is the largest.

[0048] When the left movable plate 41 abuts against the left fixed plate 40, the gap between the right movable plate 41 and the right fixed plate 40 is the largest, and the left movable plate 41 and the left fixed plate 40 are used to block the air, so that the air can enter the right side of the right partition 12 through the gap between the right movable plate 41 and the right fixed plate 40. At this time, the arc block 16 drives the bristles 17 to swing to the left, and the bristles 17 are used to clean the filter screen 11 on the left; since no air enters, the cleaning effect of the filter screen 11 is better; at the same time, In principle, when the movable plate 41 on the right is against the fixed plate 40 on the right, the gap between the movable plate 41 on the left and the fixed plate 40 on the left is the largest, and the movable plate 41 on the right and the fixed plate 40 on the right are used to block the air, so that the air can enter the left side of the left partition 12 through the gap between the movable plate 41 on the left and the fixed plate 40 on the left, and at this time, the arc block 16 drives the bristles 17 to swing to the right, and the bristles 17 are used to clean the filter 11 on the right; since no air enters, the cleaning effect on the filter 11 is better.

[0049] In this embodiment, discharge ports 70 are provided on both sides of the box body 10. The discharge is located below the air outlet 13. The discharge port 70 is close to the bottom of the box body 10. A sealing block 71 is threadedly connected to the discharge port 70. When dust removal is performed, the discharge port 70 is sealed by the sealing block 71. When the dust removal work is completed, the sealing block 71 is removed from the discharge port 70 to discharge the mixture of water and dust.
