DETAILED DESCRIPTION

[0036] The specific embodiments of the present application will be further described below with reference to the accompanying drawings, and it should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application.

[0037] In addition, the technical features involved in each of the embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0038] Please refer to the accompanying Figure 1 - the accompanying Figure 15 The present application is a slope adaptive asphalt spraying device, which comprises a base 1, and the side of the base 1 is provided with an adaptive assembly 2 and a spraying assembly 3.

[0039] In embodiment one, the adaptive assembly 2 comprises a gas delivery pipe 22, a rotating box 23, a dust suction pipe 24, a piston sleeve 25, a piston rod 26, and a connecting frame 27. The surface of the piston rod 26 is in sliding connection with the inner wall of the piston sleeve 25. The interior of the dust suction pipe 24 is in communication with the interior of the rotating box 23. The side surface of the connecting frame 27 is in rotational connection with the side surface of the rotating box 23. The gas delivery pipe 22 is in communication with the piston sleeve 25 through a hose. The inner wall of the base 1 is connected with a protective cover 21. One end of the gas delivery pipe 22 is connected with the side surface of the protective cover 21. The other end of the gas delivery pipe 22 is connected with the inner wall of the shunt pipe 34. One end of the piston sleeve 25 is in rotational connection with the inner wall of the protective cover 21. One end of the piston rod 26 is connected with the side surface of the connecting frame 27. The other end of the piston rod 26 is connected with a spring 29. One end of the spring 29 is connected with the inner wall of the piston sleeve 25. The side surface of the dust suction pipe 24 is in rotational connection with the side surface of the rotating box 23. The side surface of the connecting frame 27 is connected with the side surface of the dust suction pipe 24. The inner wall of the dust suction pipe 24 is rotatably connected with a roller 28.

[0040] Specifically, the roller 28 at the bottom of the dust suction pipe 24 directly contacts the road surface. When the device travels to a slope, the change in road surface slope will force the roller 28 to have a height difference. For example, when climbing uphill, the road surface height gradually rises, the roller 28 is pushed upward, driving the dust suction pipe 24 to deflect upward around the rotating shaft of the rotating box 23. When descending, the dust suction pipe 24 deflects downward.

[0041] When the dust suction pipe 24 deflects, the connecting frame 27 pushes the piston rod 26 to slide axially in the piston sleeve 25. The spring 29 connected to the other end of the piston rod 26 will elastically deform with the sliding distance. When climbing uphill, the piston rod 26 compresses the spring 29, and the spring 29 generates a downward counterforce to offset part of the road surface impact, so that the roller 28 closely adheres to the road surface. When descending, the spring 29 is stretched to generate an upward pulling force, which also ensures the stability of adhesion. This mechanical feedback realizes real-time self-adaptation to the change in slope.

[0042] When the piston rod 26 slides in the piston sleeve 25, the volume of the piston sleeve 25 changes. When climbing uphill, the piston rod 26 compresses the spring 29, and the volume of the piston sleeve 25 decreases, and the internal gas pressure increases. When descending, the volume increases, and the gas pressure decreases. This change in gas pressure is transmitted to the gas delivery pipe 22 through the hose, providing accurate physical signals for flow regulation of the spraying assembly.

[0043] The embodiment two, the spraying assembly 3 includes the shunt pipe 34, the positioning pipe 35, the spray pipe 36, the piston pipe 37, the air inlet pipe 38, the first spiral blade 39 and the second spiral blade 310, the inside of the shunt pipe 34 is connected with the inside of the positioning pipe 35, one end of the piston pipe 37 is connected with the side of the spray pipe 36, the side of the second spiral blade 310 is slidably connected with the inner wall of the first spiral blade 39, the side of the first spiral blade 39 is connected with the side of the air inlet pipe 38, the inner wall of the base 1 is connected with the fixed box 31, the side of the positioning pipe 35 is connected with the inner wall of the fixed box 31, the side of the air inlet pipe 38 is connected with the inner wall of the positioning pipe 35, the side of the shunt pipe 34 is connected with the side of the positioning pipe 35, the inner wall of the spray pipe 36 is slidably connected with the side of the positioning pipe 35, the inner wall of the piston pipe 37 is slidably connected with the side of the gas conveying pipe 22, the side of the second spiral blade 310 is rotatably connected with the inner wall of the spray pipe 36, the first spiral blade 39 and the second spiral blade 310 are provided with the air injection hole at the lower end of the blade, the side of the shunt pipe 34 is connected with the liquid conveying branch pipe 33, one end of the liquid conveying branch pipe 33 is connected with the liquid conveying main pipe 32, the inside of the liquid conveying branch pipe 33, the liquid conveying main pipe 32 and the shunt pipe 34 is connected;

[0044] Specifically, the asphalt enters from the liquid conveying main pipe 32, is shunted to each shunt pipe 34 through the liquid conveying branch pipe 33, and is conveyed to the spray pipe 36 through the positioning pipe 35, and the communication design of the shunt pipe 34 and the positioning pipe 35 ensures that the asphalt is evenly distributed to each spray pipe 36, laying a foundation for spraying uniformity;

[0045] The inner wall of the spray pipe 36 is slidably connected with the side of the positioning pipe 35, the spray pipe 36 can be slightly deflected along the axial direction and the radial direction of the positioning pipe 35, when the slope signal is transmitted by the assembly 2, the spray pipe 36 is linked with the gas conveying pipe 22 through the piston pipe 37 (for example, the gas pressure drives the piston pipe 37 to drive the spray pipe 36 to deflect), the spray pipe 36 is slightly adjusted downward when climbing, so that the asphalt is not moved backward due to gravity, and the spraying is insufficient, and the spray pipe 36 is slightly adjusted upward when descending, so that the spraying is excessive;

[0046] The first spiral blade 39 and the second spiral blade 310 are slidably connected in a nested mode, the blades of the two blades are staggered to form a variable channel, when the gas pressure signal is transmitted by the gas conveying pipe 22, the gas pressure drives the piston pipe 37 to drive the second spiral blade 310 to slide along the inner wall of the first spiral blade 39, when climbing, the gas pressure is increased, the second spiral blade 310 is contracted, the cross-sectional area of the channel is reduced, and the asphalt flow is reduced, when descending, the gas pressure is reduced, the second spiral blade 310 is stretched, the cross-sectional area of the channel is increased, and the flow is increased;

[0047] The first spiral blade 39 and the second spiral blade 310 drive the asphalt and the airflow to form a high-speed rotational flow, under the action of centrifugal force, large particles such as impurities or unmelted asphalt blocks in the asphalt are thrown to the inner wall of the spray pipe 36, and small and uniform asphalt particles are sprayed out through the air injection hole, effectively avoiding the problems of spraying blockage and uneven spraying.

[0048] The side of the base 1 is further provided with a dust removal assembly 4, which comprises a treatment box 41, a dust removal pipe 42, a wind box 43, a distribution pipe 44, an air inlet manifold 45, a spiral groove 46, an air outlet hole 47 and a filter screen 48. The interior of the rotating box 23 is in communication with the interior of the air inlet manifold 45. One end of the dust removal pipe 42 penetrates the inner wall of the base 1 and is in communication with the interior of the air inlet manifold 45. The other end of the dust removal pipe 42 is in communication with the interior of the spiral groove 46. The filter screen 48 is installed at the position where the spiral groove 46 is connected with the treatment box 41. The air outlet hole 47 is arranged at the position where the wind box 43 is connected with the treatment box 41. The interior of the distribution pipe 44 is in communication with the interior of the air inlet pipe 38. The side of the treatment box 41 is connected with the side of the base 1. The inner wall of the rotating box 23 is rotationally connected with the side of the air inlet manifold 45. The two ends of the air inlet manifold 45 are connected with the inner wall of the base 1. The spiral groove 46 is arranged in the inner wall of the treatment box 41. The air inlet end of the wind box 43 is in communication with the interior of the treatment box 41. The air outlet end of the wind box 43 is in communication with the interior of the distribution pipe 44.

[0049] Specifically, the wind box 43 provides negative pressure power. The road dust is sucked into through the dust suction pipe 24, sequentially passes through the rotating box 23, the air inlet manifold 45 and the dust removal pipe 42 and enters the treatment box 41. The rotational communication design of the rotating box 23 and the air inlet manifold 45 ensures that the dust suction airflow is always smooth when the dust suction pipe 24 is deflected.

[0050] The spiral groove 46 in the inner wall of the treatment box 41 makes the airflow produce rotational motion and forms a centrifugal field. The large-particle dust (such as sand and soil) in the airflow is thrown to the groove wall under the action of the centrifugal force and falls to the collection area along the spiral groove 46. The fine dust continues to move with the airflow and is intercepted and filtered through the filter screen 48. Finally, the clean air enters the wind box 43 through the air outlet hole 47.

[0051] The wind box 43 pressurizes the purified clean airflow and sends it into the distribution pipe 44, which is then transmitted to the first spiral blade 39 and the second spiral blade 310 of the spraying assembly 3 through the air inlet pipe 38. This design utilizes the airflow after dust removal as spraying power for the second time, reduces energy waste and improves the energy efficiency of the device.

[0052] Working principle:

[0053] Firstly, the adaptive assembly 2 perceives the slope in real time and dynamically adjusts, through mechanical structure and air pressure feedback linkage, to ensure that the device conforms to the change of road slope, the rollers 28 at the bottom of the dust suction pipe 24 directly contact the road surface, when the road surface has a slope, the rollers 28 drive the dust suction pipe 24 to rotate around the rotating box 23, the dust suction pipe 24 pushes the piston rod 26 to slide in the piston sleeve 25 through the connecting frame 27, the spring 29 at the other end of the piston rod 26 generates a reverse elastic force according to the change of slope, forming a buffer and self-adaptive adjustment, the rotating box 23 is rotationally connected with the air inlet manifold 45, ensuring that the dust suction pipe 24 does not affect the air flow passage when rotating with the slope, the piston rod 26 changes the internal volume of the piston sleeve 25 when sliding, the air pressure change is transmitted to the air conveying pipe 22 through the hose, providing a signal for the flow adjustment of the spraying assembly 3;

[0054] The dust removal assembly 4 removes dust from the road surface before asphalt spraying, and at the same time uses the purified air flow to power the spraying assembly 3, realizing efficient use of energy, the inside of the rotating box 23 is in communication with the air inlet manifold 45, when the dust suction pipe 24 conforms to the road surface with the slope, the road dust is sucked into the air inlet manifold 45 through the rotating box 23, the dust enters the spiral groove 46 on the inner wall of the treatment box 41 through the dust removal pipe 42, the spiral structure makes the air flow rotate to generate centrifugal force, separating large particles of dust, the air flow carrying fine dust is filtered through the filter screen 48, the purified air enters the bellows 43 through the air outlet hole 47, the bellows 43 sends the clean air flow into the distribution pipe 44, and then the clean air flow is transmitted to the spraying assembly 3 through the air inlet pipe 38, providing power for asphalt spraying.

[0055] The spraying assembly 3 dynamically adjusts the asphalt spraying angle and flow according to the air pressure signal transmitted by the adaptive assembly 2, ensuring uniform spraying on the slope, the asphalt is divided into the liquid conveying branch pipe 33 through the liquid conveying main pipe 32, then enters the shunt pipe 34, and finally is conveyed to the spray pipe 36 through the positioning pipe 35, the positioning pipe 35 is fixed in the fixed box 31 to provide sliding support for the spray pipe 36, ensuring the stability of spraying, the clean air flow of the dust removal assembly 4 is introduced into the air inlet pipe 38, the air flow is sprayed out through the air injection holes of the first spiral blade 39 and the second spiral blade 310, the air pressure generated by the high flow rate can drive the asphalt to be sprayed through the spray pipe 36, and the rotational flow generated by the air flow driven by the first spiral blade 39 and the second spiral blade 310 separates large particles in the asphalt, improving the uniformity of spraying, the spraying assembly 3 receives the air pressure signal and air flow power, adjusts the distance through the telescopic adjustment of the spray pipe 36, adjusts the flow through the length change between the first spiral blade 39 and the second spiral blade 310, and finally realizes uniform asphalt spraying on the slope, thus the whole working process is completed.
