Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a building foundation drilling device. Background Art

[0002] With the acceleration of the urbanization process and the continuous advancement of infrastructure construction, the demand for efficient, precise, and safe drilling devices is increasing. In addition, with the improvement of environmental awareness, there is also a high market demand for drilling devices with low noise, low vibration, and low emissions. Therefore, the market for building foundation drilling devices has great potential and development space.

[0003] Existing building foundation drilling usually uses a rotary drilling rig to drill foundation pile holes. When the rotary drilling rig is working, it will bring soil clods and sand and gravel to the ground through the spiral chip removal grooves on the surface. The soil clods and sand and gravel accumulate at the edge of the pile hole. Affected by the weight of the soil clods and sand and gravel, it is easy to cause the collapse of the pile hole opening position. The soil clods and sand and gravel may fall back into the hole again, which is likely to cause the drill bit to become stuck in the pile hole, affecting the subsequent grouting process. Moreover, the falling sand and gravel are likely to damage the surface of the drill bit, and it is necessary for the operator to collect them with a shovel. Since the rotary drilling rig is usually directly connected to the drive shaft and there is no protection measure on the outside, the personal safety of the operator cannot be guaranteed during the shoveling process. At the same time, the dust generated after the sand and gravel are lifted is easy to pollute the construction environment and affect the physical and mental health of the operator. Therefore, the present application provides a building foundation drilling device to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a building foundation drilling device to solve the problems that existing building foundation drilling usually uses a rotary drilling rig to drill foundation pile holes. When the rotary drilling rig is working, it will bring soil clods and sand and gravel to the ground through the spiral chip removal grooves on the surface. The soil clods and sand and gravel accumulate at the edge of the pile hole. Affected by the weight of the soil clods and sand and gravel, it is easy to cause the collapse of the pile hole opening position. The soil clods and sand and gravel may fall back into the hole again, which is likely to cause the drill bit to become stuck in the pile hole, affecting the subsequent grouting process. Moreover, the falling sand and gravel are likely to damage the surface of the drill bit, and it is necessary for the operator to collect them with a shovel. Since the rotary drilling rig is usually directly connected to the drive shaft and there is no protection measure on the outside, the personal safety of the operator cannot be guaranteed during the shoveling process. At the same time, the dust generated after the sand and gravel are lifted is easy to pollute the construction environment and affect the physical and mental health of the operator.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

The drilling assembly includes a rotating disk installed at the output end of the driving motor, and a plurality of telescopic rods are equiangularly distributed at the bottom end of the rotating disk, and a gripper is connected to the bottom end of the rotating disk.

[0007] Optionally, a drill bit is connected to the end of the gripper, a sleeve is connected between the bottoms of the plurality of telescopic rods, the bottom end of the sleeve is connected with a positioning ring, and the sleeve rotates on the top end of the positioning ring.

[0008] Optionally, the fixing assembly includes a connecting frame which is equiangularly distributed at the bottom end of the positioning ring. There are four groups of the connecting frames. The bottom end of each group of connecting frames is connected with a fixing arm, and two support arm seats are symmetrically connected to the outside of each group of connecting frames.

[0009] Optionally, an auxiliary support arm is connected to the inside of each support arm seat through a pin shaft, the tail end of the auxiliary support arm is connected with a mounting frame through a pin shaft, the mounting frame rotates at the tail end of the auxiliary support arm, one end of the mounting frame is connected with an anti-slip plate which rotates at one end of the mounting frame, and a roller is connected to the inside of the mounting frame which rotates on the inside of the mounting frame.

[0010] Optionally, the collecting assembly includes a rotating shaft sleeved on the outside of the sleeve, a guiding groove is arranged on the surface of the rotating shaft, a mounting box is sleeved on the outside of the rotating shaft, the mounting box is installed on the top end of the positioning ring, a dust-proof cover is sleeved on the outside of the mounting box and is located on the outside of the sleeve, and the rotating shaft rotates inside the mounting box.

[0011] Optionally, two sets of sliding grooves are symmetrically arranged on the inner side of the installation box. A connecting plate is installed inside each set of sliding grooves. The connecting plate slides inside the sliding groove. One side of the connecting plate is connected to a guide rod. The guide rod slides inside the guide groove. A spring is sleeved on the outer side of the guide rod. The tail end of the spring is connected to the end of the connecting plate. Two sets of scraping plates are symmetrically connected to the outer side wall of the rotating shaft. A shoveling plate is connected to the bottom end of the scraping plate. An anti-slip wheel is connected to the end of the shoveling plate. Two collection ports are symmetrically arranged on the outer side of the dust-proof cover.

[0012] Optionally, the dust-proof component includes a sleeve. The sleeve is installed on one side of the connecting plate. The sleeve slides inside the installation box. An elastic telescopic rod is connected inside the sleeve. The tail end of the elastic telescopic rod is connected to the inner wall of the installation box.

[0013] Optionally, a fogging nozzle is connected to the top end of the sleeve. A synchronous frame is connected to the outer side of the sleeve. A piston rod is nested inside the synchronous frame. The piston rod penetrates through the top end of the water tank. A piston is connected to the end of the piston rod. A water tank is sleeved on the outer side of the piston.

[0014] Optionally, the piston slides inside the water tank. The water tanks are symmetrically installed on the outer side of the installation box. A one-way valve is connected to one side of the water tank. The one-way valve is connected to the fogging nozzle through a pipeline. A filling port is connected to one side of the water tank.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above solution, by providing a collection component, the two sets of scraping plates on the outer side are driven by the rotating shaft during rotation to scrape and collect the sandy soil generated by drilling at the top of the installation box. The sandy soil is exported from the collection port of the dust-proof cover. The operator connects a sandy soil collection bag to the collection port to collect the sandy soil, which can efficiently collect the drilling chips, will not cause harm to the personal safety of the operator, and at the same time, avoids a large amount of sand chips from accumulating at the position of the pile hole opening, resulting in the collapse of the foundation pile hole, and avoids the drill bit from getting stuck due to untimely chip removal during drilling, improving the work efficiency.

[0017] By providing a dust-proof component, the movement of the piston rod is driven by the sleeve. The piston squeezes water in the water tank to replenish water to the fogging nozzle, so that the atomized water can be sprayed at different heights, increasing the air humidity in the dust-proof cover, reducing the floating amount of dust in the air, avoiding pollution to the surrounding environment during construction, and at the same time, reducing the impact on the physical health of the operator during construction.

[0018] By setting a fixing component, after the fixing arm is inserted into the ground, the force arms of the fixing arm and the auxiliary support arm form a perpendicular state. At the same time, the anti-slip plate closely adheres to the ground to prevent the auxiliary support arm from slipping on the ground, improving stability. While the structure positions the foundation drilling, it provides sufficient support force for the drill bit in the drilling hole, avoiding the drill bit hitting a relatively hard geological structure. Since the driving force application point of the drill bit is too high, it may cause the drill bit to tilt during the drilling operation, resulting in construction errors and reducing the possibility of excessive wear and fracture of the drill bit.

[0041] As Figures 1 to 13 shown, an embodiment of the present invention provides a building foundation drilling device, including a crawler vehicle 1, a tipping platform 2 is provided on the top of the crawler vehicle 1, a slide rail frame 3 is provided on the top of the tipping platform 2, a driving motor 4 is provided on the slide rail frame 3, and further includes a drilling assembly 5, the drilling assembly 5 is installed at the output end of the driving motor 4, the drilling assembly 5 is used for drilling the foundation, a fixing assembly 6, the fixing assembly 6 is installed at the bottom end of the drilling assembly 5, the fixing assembly 6 is used for drilling positioning, a collecting assembly 7, the collecting assembly 7 is installed on the fixing assembly 6, the collecting assembly 7 is used for collecting the soil blocks generated by drilling to a place away from the foundation hole position, and a dust prevention assembly 8, the dust prevention assembly 8 is installed on one side of the collecting assembly 7, the dust prevention assembly 8 is used for dust prevention of the soil blocks generated by drilling by atomizing and spraying water.

[0042] As Figures 1 to 4As shown, the drilling assembly 5 includes a rotating disk 51, which is installed at the output end of the driving motor 4. A plurality of telescopic rods 52 are arranged at equal angles at the bottom end of the rotating disk 51. A gripper 53 is connected to the bottom end of the rotating disk 51, and a drill bit 54 is connected to the end of the gripper 53. A sleeve 55 is connected between the bottoms of the plurality of telescopic rods 52, and a positioning ring 56 is connected to the bottom end of the sleeve 55. The sleeve 55 rotates on the top end of the positioning ring 56. By providing the drilling assembly 5, the operator moves the crawler vehicle 1 to the designated position, flips the turning platform 2 through a control module (not marked in the figure), the slide rail frame 3 is perpendicular to the plane to be drilled, and the control module (not marked in the figure) makes the slide rail frame 3 drive the driving motor 4 to move vertically downward, so that the rotating disk 51 moves downward following the driving motor 4, and the sleeve 55 and the positioning ring 56 connected to the rotating disk 51 through the telescopic rods 52 move downward, thereby driving the drill bit 54 to move toward the drilling ground. During the drilling operation, the driving motor 4 drives the rotating disk 51 and the drill bit 54 to rotate, and the rotating disk 51 drives the sleeve 55 to rotate through the connection of the telescopic rods 52. The telescopic rods 52 can block the drill bit 54 inside to prevent the drill bit 54 from idling and jumping, causing injury to the operator.

[0043] As Figure 1 , Figure 2 and Figure 5As shown, the fixing component 6 includes a connecting frame 61. The connecting frames 61 are arranged at equal angles at the bottom end of the positioning ring 56. There are four groups of connecting frames 61. The bottom end of each group of connecting frames 61 is connected with a fixing arm 62. Two support arm seats 63 are symmetrically connected to the outside of each group of connecting frames 61. An auxiliary support arm 64 is connected to the inside of each support arm seat 63 through a pin shaft. The tail end of the auxiliary support arm 64 is connected with a mounting frame 65 through a pin shaft. The mounting frame 65 rotates at the tail end of the auxiliary support arm 64. One end of the mounting frame 65 is connected with an anti-slip plate 66. The anti-slip plate 66 rotates at one end of the mounting frame 65. A roller 67 is connected to the inside of the mounting frame 65. The roller 67 rotates inside the mounting frame 65. By setting the fixing component 6, the sleeve 55 and the positioning ring 56 connected to the rotary disk 51 through the telescopic rod 52 move downward. The fixing arm 62 is inserted into the ground through the tooth structure at the bottom end for positioning and fixing before drilling. During the downward movement of the fixing arm 62, the roller 67 rolls on the ground, and the auxiliary support arm 64 flips inside the support arm seat 63. When more than half of the fixing arm 62 is inserted into the ground, affected by the weight of the auxiliary support arm 64 and the blocking force of the ground, the expansion of the auxiliary support arm 64 drives the mounting frame 65 to rotate at the end of the auxiliary support arm 64, so that the anti-slip plate 66 contacts the ground through flipping. When the fixing arm 62 is completely inserted into the ground, the force arms of the fixing arm 62 and the auxiliary support arm 64 form a perpendicular state. At the same time, the anti-slip plate 66 closely adheres to the ground to prevent the auxiliary support arm 64 from slipping on the ground, improving stability. While the structure positions the foundation drilling, it provides sufficient support force for the drill bit 54 in the drilling hole, avoiding the drill bit 54 hitting a harder geological structure, resulting in the drill bit 54 tilting during the drilling operation due to the too high driving force application point of the drill bit 54, generating construction errors, and reducing the possibility of excessive wear and fracture of the drill bit 54.

[0044] As Figure 6 、 Figures 8 to 10As shown, the collecting assembly 7 includes a rotating shaft 71, which is sleeved on the outside of the sleeve 55. A guide groove 72 is provided on the surface of the rotating shaft 71. A mounting box 73 is sleeved on the outside of the rotating shaft 71. The mounting box 73 is mounted on the top of the positioning ring 56 by bolts. A dust cover 730 is provided on the outside of the mounting box 73. The dust cover 730 is located on the outside of the sleeve 55. The rotating shaft 71 rotates on the inside of the mounting box 73. Two groups of sliding grooves 74 are symmetrically provided on the inside of the mounting box 73. A connecting plate 75 is installed on the inside of each group of sliding grooves 74. The connecting plate 75 slides on the inside of the sliding groove 74. One side of the connecting plate 75 is connected to A guide rod 76, the guide rod 76 slides on the inner side of the guide groove 72, a spring 77 is sleeved on the outer side of the guide rod 76, the tail end of the spring 77 is connected to the end of the connecting plate 75, two groups of scrapers 78 are symmetrically connected to the outer wall of the rotating shaft 71, the scrapers 78 are set to be arc-shaped, the scrapers 78 are made of polycarbonate plastic material, the bottom end of the scrapers 78 is connected to a shovel plate 780, the cross section of the shovel plate 780 is set to be a right-angled trapezoid, the end of the shovel plate 780 is connected to an anti-skid wheel 781, the anti-skid wheel 781 is made of rubber material, and the surface of the anti-skid wheel 781 is provided with an anti-skid edge block, and two collecting ports 79 are symmetrically provided on the outer side of the dust cover 730;

[0045] By setting the collecting assembly 7, during the drilling operation of the drill bit 54, the sand and soil produced by the drilling will be sprinkled out from the inner side of the sleeve 55 along the spiral blade surface of the drill bit 54, and the dust cover 730 can effectively avoid the smoke and dust produced by the splashing of sand and soil, and at the same time, reduce the safety impact of the splashing of stones in the sand and soil on the surrounding operators. The sand and stones are accumulated on the top of the installation box 73, and the rotating disk 51 drives the sleeve 55 to rotate through the connection of the telescopic rod 52, and the rotating shaft 71 rotates with the sleeve 55, and the guide rod 76 slides on the inner side of the N-shaped guide groove 72. The deformation pressure generated by the spring 77 makes the guide rod 76 always on the inner side of the guide groove 72 and will not be separated from the inner side of the guide groove 72. The guide rod 76 drives the connecting plate 75 connected to the tail end to slide on the inner side of the sliding groove 74, and the rotating shaft 71 drives the two groups of outer The scraper 78 scrapes and collects the sand and soil generated by the drilling at the top of the installation box 73. Since the shovel plate 780 is set to a right-angled trapezoid and has an inclined blade surface, the shovel plate 780 at the bottom of the scraper plate 78 can scrape out wet mud and silt to the outside. The anti-skid wheel 781 assists in rolling on one side of the shovel plate 780, providing sufficient friction for the shovel plate 780 and the scraper plate 78 to avoid slipping during scraping and collection. The sand and soil products are discharged from the collection port 79 of the dust cover 730. The operator can collect the sand and soil by connecting a sand collection bag to the collection port 79, which can efficiently collect the drilling chips without causing harm to the personal safety of the operator. At the same time, it avoids the accumulation of a large amount of sand and gravel chips at the pile hole mouth, causing the foundation pile hole to collapse, and avoids the drill bit 54 from being stuck due to untimely chip removal during drilling, thereby improving work efficiency.

[0046] As Figures 10 to 13 shown, the dust-proof component 8 includes a sleeve 81. The sleeve 81 is installed on one side of the connecting plate 75. The sleeve 81 slides inside the installation box 73. An elastic telescopic rod 82 is connected to the inside of the sleeve 81. The tail end of the elastic telescopic rod 82 is connected to the inner wall of the installation box 73. A mist spray head 83 is connected to the top end of the sleeve 81. A synchronous frame 84 is connected to the outside of the sleeve 81. A piston rod 85 is nested inside the synchronous frame 84. The piston rod 85 penetrates through the top end of the water tank 87. A piston 86 is connected to the end of the piston rod 85. A water tank 87 is sleeved outside the piston 86. The piston 86 slides inside the water tank 87. The water tanks 87 are symmetrically installed on the outside of the installation box 73. A one-way valve 88 is connected to one side of the water tank 87. The one-way valve 88 is connected to the mist spray head 83 through a pipeline. A filling port 870 is connected to one side of the water tank 87;

[0047] By setting the dust-proof component 8, the rotating disk 51 drives the shaft sleeve 55 to rotate through the connection of the telescopic rod 52. The rotating shaft 71 rotates following the shaft sleeve 55. The rotation of the rotating shaft 71 causes the guide rod 76 to slide along the guide groove 72. Due to the deformation pressure generated by the spring 77, the guide rod 76 always closely adheres to the inside of the guide groove 72 and will not disengage from the inside of the guide groove 72. Since the rotating shaft 71 continuously rotates, when the guide rod 76 reaches the lowest point of the N-shaped guide groove 72, the guide rod 76 no longer receives the squeezing force in the vertical direction from the guide groove 72 in the vertical direction. The elastic telescopic rod 82 pushes the sleeve 81 to move upward against gravity, causing the connecting plate 75 to move upward inside the sliding groove 74, thereby driving the guide rod 76 to reach the highest point of the N-shaped guide groove 72, so that the rotating shaft 71 rotates one week. The guide rod 76 moves from the highest point of the N-shaped guide groove 72 along the arc part to the lowest point of the N-shaped guide groove 72. During this process, the guide rod 76 drives the connecting plate 75 connected to the tail end to slide downward inside the sliding groove 74, thereby driving the sleeve 81 to move vertically downward inside the installation box 73. The elastic telescopic rod 82 connected to the bottom end inside the sleeve 81 is compressed under force, achieving the effect that the sleeve 81 makes two reciprocating motions in the vertical direction inside the installation box 73,

[0048] During the movement of the sleeve 81, through the connection of the synchronous frame 84 on the corresponding side, the piston rod 85 and the sleeve 81 can move at the same speed. When the piston rod 85 moves downward, the piston 86 slides downward inside the water tank 87, so that the piston 86 is located below the filling port 870 of the water tank 87. The external water pipe conveys water from the filling port 870 above the piston 86. The piston 86 moves upward, squeezing the water in the chamber above the piston 86, causing the water to enter the one-way valve 88 and enter the atomizing nozzle 83 through the pipeline. After the water is atomized, it is sprayed inside the dust-proof cover 730. When the sleeve 81 moves downward, it drives the piston rod 85 to push the piston 86 downward through the connection of the synchronous frame 84. Through the up and down movement of the sleeve 81, the atomized water can be sprayed at different heights, so as to increase the air humidity in the dust-proof cover 730, reduce the floating amount of dust in the air, avoid polluting the surrounding environment during construction, and at the same time, reduce the impact on the physical health of the operators during construction.

[0049] The working principle of the technical solution provided by the present invention is as follows:

[0050] The operator moves the crawler vehicle 1 to the designated position, flips the flipping table 2 through the control module (not marked in the figure). The slide rail frame 3 is perpendicular to the plane to be drilled. Through the control module (not marked in the figure), the slide rail frame 3 drives the driving motor 4 to move vertically downward, so that the rotating disk 51 follows the driving motor 4 to move downward, and the bushing 55 and the positioning ring 56 connected to the rotating disk 51 through the telescopic rod 52 move downward, thereby driving the drill bit 54 to move closer to the drilling ground. During the drilling operation, the driving motor 4 drives the rotating disk 51 and the drill bit 54 to rotate, and the rotating disk 51 drives the bushing 55 to rotate through the connection of the telescopic rod 52.

[0051] The shaft sleeve 55 and the positioning ring 56 connected to the rotating disk 51 through the telescopic rod 52 move downward, and the fixed arm 62 is inserted into the ground through the toothed structure at the bottom for positioning and fixing before drilling. During the downward movement of the fixed arm 62, the roller 67 rolls on the ground, and the auxiliary support arm 64 turns over on the inner side of the support arm seat 63. When the fixed arm 62 is inserted into the ground more than half, the roller 67 is affected by the weight of the auxiliary support arm 64 and the barrier force of the ground, so that when the auxiliary support arm 64 is unfolded, it drives the mounting frame 65 to rotate at the end of the auxiliary support arm 64, so that the anti-slip The plate 66 contacts the ground by flipping, and when the fixed arm 62 is fully inserted into the ground, the force arm of the fixed arm 62 and the auxiliary support arm 64 forms a vertical state. At the same time, the anti-slip plate 66 is close to the ground to prevent the auxiliary support arm 64 from slipping on the ground, thereby improving stability. While the structure is positioning the foundation drilling hole, it provides sufficient support force for the drill bit 54 in the drilling hole to prevent the drill bit 54 from hitting a harder geological structure. Since the driving force point of the drill bit 54 is too high, the drill bit 54 will tilt during the drilling operation, resulting in construction errors and reducing the possibility of excessive wear and breakage of the drill bit 54.

[0052] When the drill bit 54 is drilling, the sand and soil generated by drilling will be scattered from the inner side of the sleeve 55 along the spiral blade surface of the drill bit 54. The dust cover 730 can effectively prevent the smoke and dust generated by the splashing of sand and soil. At the same time, it reduces the safety impact of the splashing of stones in the sand and soil on the surrounding operators. The sand and stones are accumulated on the top of the installation box 73. The rotating disk 51 drives the sleeve 55 to rotate through the connection of the telescopic rod 52. The rotating shaft 71 rotates with the sleeve 55. The guide rod 76 slides on the inner side of the N-shaped guide groove 72. The deformation pressure generated by the spring 77 ensures that the guide rod 76 is always on the inner side of the guide groove 72 and will not be separated from the inner side of the guide groove 72. The guide rod 76 drives the connecting plate 75 connected to the tail end to slide on the inner side of the sliding groove 74. The rotating shaft 71 drives the two sets of scrapers 78 on the outer side during rotation. The sand and soil generated by the drilling at the top of the installation box 73 is scraped and collected. Since the shovel plate 780 is set to a right-angle trapezoid and has an inclined blade surface, the shovel plate 780 at the bottom of the scraper plate 78 can scrape out wet mud and silt to the outside. The anti-skid wheel 781 assists in rolling on one side of the shovel plate 780 to provide sufficient friction for the shovel plate 780 and the scraper plate 78 to avoid slipping during scraping and collection. The sand and soil products are discharged from the collection port 79 of the dust cover 730. The operator can collect the sand and soil by connecting a sand collection bag to the collection port 79, which can efficiently collect the drilling chips without causing harm to the personal safety of the operator. At the same time, it avoids the accumulation of a large amount of sand and gravel chips at the pile hole mouth, which causes the collapse of the foundation pile hole, and avoids the jamming of the drill bit 54 due to untimely chip removal during drilling, thereby improving work efficiency.

[0053] The rotating disk 51 drives the sleeve 55 to rotate through the connection of the telescopic rod 52. The rotating shaft 71 rotates following the sleeve 55. The rotation of the rotating shaft 71 causes the guide rod 76 to slide along the guide groove 72. Due to the deformation pressure generated by the spring 77, the guide rod 76 always clings to the inner side of the guide groove 72 and will not disengage from the inner side of the guide groove 72. Since the rotating shaft 71 continues to rotate, when the guide rod 76 reaches the lowest point of the N-shaped guide groove 72, the guide rod 76 no longer receives the squeezing pressure in the vertical direction from the guide groove 72 in the vertical direction. This enables the elastic telescopic rod 82 to push the sleeve 81 to move upward against gravity, causing the connecting plate 75 to move upward inside the sliding groove 74, thereby driving the guide rod 76 to reach the highest point of the N-shaped guide groove 72, and thus making the rotating shaft 71 rotate one week. The guide rod 76 moves from the highest point of the N-shaped guide groove 72 along the arc part to the lowest point of the N-shaped guide groove 72. During this process, the guide rod 76 drives the connecting plate 75 connected to the tail end to slide downward inside the sliding groove 74, thereby driving the sleeve 81 to move vertically downward inside the mounting box 73. The elastic telescopic rod 82 connected to the bottom end inside the sleeve 81 is compressed under force. The sleeve 81 achieves the effect of reciprocating vertically twice inside the mounting box 73. During the movement of the sleeve 81, through the connection of the synchronous frame 84 on the corresponding side, the piston rod 85 and the sleeve 81 can move at the same speed. When the piston rod 85 moves downward, the piston 86 slides downward inside the water tank 87, making the piston 86 located below the filling port 870 of the water tank 87. (Since the one-way valve 88 can only flow in one direction from the water tank 87 to the atomizing nozzle 83), at this time, water is gradually conveyed from the filling port 870 to the upper part of the piston 86 through the external water pipe by its own water pressure and gradually fills the upper half of the water tank 87. When the piston rod 85 moves upward, it drives the piston 86 to move upward, squeezing the water in the chamber above the piston 86, causing the water to enter the pipeline through the one-way valve 88 and enter the atomizing nozzle 83. The water is atomized by the atomizing nozzle 83 and sprayed inside the dust-proof cover 730. When the sleeve 81 moves downward, it drives the piston rod 85 to push the piston 86 downward through the connection of the synchronous frame 84. Through the up and down movement of the sleeve 81, the atomized water can be sprayed at different heights to increase the air humidity inside the dust-proof cover 730, reduce the floating amount of dust in the air, avoid polluting the surrounding environment during construction, and at the same time, reduce the impact on the physical health of the operators during construction.
