Description

Technical Field

[0001] The utility model relates to the technical field of asphalt paving equipment, and specifically, to a paving equipment for high-viscosity emulsified asphalt mixture. Background Art

[0002] Asphalt paving is the process of evenly paving asphalt mixture on the road base and performing preliminary compaction and leveling. Asphalt paving equipment is generally divided into two types: crawler type and tire type, and consists of two parts: traction, paving, compaction, and screeding.

[0003] The utility model with the publication number of CN215758374U discloses a paving equipment for high-viscosity emulsified asphalt mixture, including: a paving mechanism, a bracket, a separation tank, a dust suction mechanism, an air inlet pipe, a suction fan, an exhaust pipe, and a blowing mechanism. The paving mechanism is the working end of the paver, and a pressure roller and a paving screw are arranged on the paving mechanism. The separation tank is fixedly connected to the upper end of the paving mechanism through the bracket. The dust suction mechanism is arranged on the front side of the paving mechanism. In the above application document, negative pressure is generated at the dust suction pipe of the dust suction mechanism to suck in smaller dust. One aspect of the brush on the dust suction pipe can sweep the dust on the ground, but the relatively static brush has a poor effect on sweeping the dust on the ground, and there may still be some dust adhering to the ground, affecting the subsequent paving work. Summary of the Utility Model

[0004] The utility model provides a paving equipment for high-viscosity emulsified asphalt mixture, which solves the problems of a paving equipment for high-viscosity emulsified asphalt mixture in the related art.

[0005] The technical solution of the present utility model is as follows: A paving device for high-viscosity emulsified asphalt mixture, including a carrier. A steering wheel is provided at the bottom of the carrier. A rotating shaft is rotatably connected inside the carrier. A rotating wheel is fixedly connected to the surface of the rotating shaft. A collection box and an asphalt barrel are fixedly connected to the top of the carrier. An air suction pump is provided at the top of the collection box. A dust suction pipe is provided at the front end of the air suction pump. An extraction pump is provided at the top of the asphalt barrel. A spray pipe is provided at the front end of the extraction pump. A connecting frame is fixedly connected to the front end of the carrier. A flattening roller is rotatably connected inside the connecting frame. A cleaning mechanism and a knocking mechanism are provided at the front end of the carrier. The cleaning mechanism includes a rotating gear, a hydraulic chamber and a bracket. The rotating gear is fixedly connected to the surface of the rotating shaft. The hydraulic chamber penetrates and is fixedly connected to the front end of the carrier. A piston rod is slidably connected to the inner part of one end of the hydraulic chamber. A toothed rod is fixedly connected to the bottom of the piston rod. A push rod is slidably connected to the inner part of the other end of the hydraulic chamber. The bracket is fixedly connected to the front end of the carrier. A sliding rod is fixedly connected inside the bracket. A return spring is provided on the surface of the sliding rod. A cleaning brush is slidably connected to the surface of the sliding rod through the return spring. The end of the push rod away from the hydraulic chamber is fixedly connected to the cleaning brush.

[0006] Further, the bottom of the rotating wheel and the bottom of the steering wheel are initially on the same horizontal plane. The steering wheel is used for the steering of the carrier. When the carrier moves, the rotating wheel will rotate.

[0007] Further, the end of the spray pipe away from the extraction pump is close to the flattening roller. A dust suction hood is provided at the end of the dust suction pipe away from the air suction pump. The asphalt sprayed by the spray pipe will fall to the rear end of the flattening roller. When the flattening roller passes by, it will flatten the asphalt. When the dust suction pipe sucks air, it will suck the dust on the ground through the dust suction hood.

[0008] Further, the rotating gear is an incomplete gear, and the teeth on the rotating gear are adapted to the teeth on the toothed rod. When the rotating gear rotates and meshes with the toothed rod, it will drive the toothed rod to move upward.

The pneumatic chamber penetrates and is fixedly connected to the front end of the carrier. An airbag is provided at one end of the pneumatic chamber. A striking rod is slidably connected to the inner part of the other end of the pneumatic chamber.

[0010] Further, the length of the collision block is greater than the distance from the surface of the rotating shaft to the airbag. The airbag is in an inflated state initially. When the rotating shaft rotates, it will drive the collision block to repeatedly squeeze the airbag. When the airbag is squeezed, the air pressure inside it will enter the pneumatic chamber and push the striking rod to move forward.

[0011] Further, the end of the impact rod away from the air pressure chamber is close to the cleaning brush, and a rubber pad is provided at the end of the impact rod away from the air pressure chamber. When the impact rod moves forward, it will hit the cleaning brush, and the rubber pad at the front end of the impact rod can prevent damage to the cleaning brush.

[0012] The working principle and beneficial effects of the present utility model are as follows:

[0013] 1. By providing a cleaning mechanism in the present utility model, when the carrier is connected to the vehicle body at the rear end of the carrier and the vehicle body drives the carrier to move, the rotating wheel will rotate when it contacts the ground. The rotation of the rotating wheel drives the rotation of the rotating shaft, and the rotation of the rotating shaft will drive the cleaning brush to move back and forth through the cooperation of components such as the rotating gear, the toothed rod, and the hydraulic chamber, improving the cleaning effect on the ground.

[0014] 2. By providing a knocking mechanism in the present utility model, when the rotating shaft rotates, it will also drive the impact rod to repeatedly hit the cleaning brush through the cooperation of components such as the collision block, the airbag, and the air pressure chamber, causing the cleaning brush to vibrate and shaking off the dust on the cleaning brush, preventing too much dust from adhering to the cleaning brush and affecting the subsequent cleaning effect.

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1 to 3 shown, this embodiment proposes a paving device for high-viscosity emulsified asphalt mixture, including a carrier 1. Steering wheels 2 are provided at the bottom of the carrier 1. A rotating shaft 3 is rotatably connected inside the carrier 1. A rotating wheel 4 is fixedly connected to the surface of the rotating shaft 3. The bottom of the rotating wheel 4 and the bottom of the steering wheel 2 are in the same horizontal plane in the initial state. The steering wheel 2 is used for the steering of the carrier. When the carrier 1 moves, the rotating wheel 4 will rotate. A collection box 5 and an asphalt barrel 8 are fixedly connected to the top of the carrier 1. An air suction pump 6 is provided at the top of the collection box 5. A dust suction pipe 7 is provided at the front end of the air suction pump 6. An extraction pump 9 is provided at the top of the asphalt barrel 8. A spray pipe 10 is provided at the front end of the extraction pump 9. A connecting frame 13 is fixedly connected to the front end of the carrier 1. A flattening roller 14 is rotatably connected inside the connecting frame 13. One end of the spray pipe 10 away from the extraction pump 9 is close to the flattening roller 14. The asphalt sprayed by the spray pipe 10 will fall to the rear end of the flattening roller 14. When the flattening roller 14 passes by, it will flatten the asphalt. When the dust suction pipe 7 sucks air, it will suck the dust on the ground through the dust suction hood. A cleaning mechanism 11 and a knocking mechanism 12 are provided at the front end of the carrier 1. The cleaning mechanism 11 includes a rotating gear 111, a hydraulic chamber 112 and a bracket 116. The rotating gear 111 is fixedly connected to the surface of the rotating shaft 3. The hydraulic chamber 112 penetrates and is fixedly connected to the front end of the carrier 1. A pressure rod 113 is slidably connected to the piston inside one end of the hydraulic chamber 112. A toothed rod 114 is fixedly connected to the bottom of the pressure rod 113. The rotating gear 111 is an incomplete gear, and the teeth on the rotating gear 111 are adapted to the teeth on the toothed rod 114. When the rotating gear 111 rotates and meshes with the toothed rod 114, it will drive the toothed rod 114 to move upward. A push rod 115 is slidably connected to the piston inside the other end of the hydraulic chamber 112. The bracket 116 is fixedly connected to the front end of the carrier 1. A sliding rod 117 is fixedly connected to the inside of the bracket 116. A return spring 118 is provided on the surface of the sliding rod 117. A cleaning brush 119 is slidably connected to the surface of the sliding rod 117 through the return spring 118. One end of the push rod 115 away from the hydraulic chamber 112 is fixedly connected to the cleaning brush 119.

[0025] In this embodiment, when asphalt needs to be paved on the ground, the rear end of the carrier 1 is connected to the vehicle body, and the vehicle body drives the carrier 1 to move in the direction away from the flattening roller 14. The steering wheel 2 is used for the steering of the carrier 1. When the rotating wheel 4 rotates due to friction with the ground, the rotating wheel 4 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the rotating gear 111 to rotate. At the beginning, when the rotating gear 111 rotates and meshes with the toothed rod 114, it drives the toothed rod 114 to move upward. The upward movement of the toothed rod 114 drives the pressure rod 113 to move upward. The upward movement of the pressure rod 113 drives the push rod 115 to move out of the hydraulic chamber 112 through the hydraulic pressure in the hydraulic chamber 112. The movement of the push rod 115 drives the cleaning brush 119 to move. When the rotating gear 111 rotates to the part without teeth and disengages from the toothed rod 114, the return spring 118 drives the cleaning brush 119 to move in the reverse direction to restore, the push rod 115 moves back into the hydraulic chamber 112 to restore, and the hydraulic pressure in the hydraulic chamber 112 drives the pressure rod 113 and the toothed rod 114 to move downward to restore, thus forming a cycle. The cleaning brush 119 moves back and forth to clean the passing road surface to prevent dust adhesion. The suction pump 6 sucks the dust on the cleaned road surface through the suction pipe 7, and the dust is stored in the collection box 5 to further improve the cleaning effect. Subsequently, the extraction pump 9 can be turned on to extract the asphalt in the asphalt barrel 8 and spray it onto the ground through the spray pipe 10. When the flattening roller 14 passes, it flattens the asphalt.

[0026] Embodiment 2

[0027] As Figures 1 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes a knocking mechanism 12, including a collision block 121 and a pneumatic chamber 122. The collision block 121 is fixedly connected to the surface of the rotating shaft 3. The pneumatic chamber 122 penetrates and is fixedly connected to the front end of the carrier 1. One end of the pneumatic chamber 122 is provided with an airbag 123. The other end of the pneumatic chamber 122 is internally slidably connected with an impact rod 124. The length of the collision block 121 is greater than the distance from the surface of the rotating shaft 3 to the airbag 123. The airbag 123 is in an inflated state in the initial state. When the rotating shaft 3 rotates, it drives the collision block 121 to repeatedly squeeze the airbag 123. The internal air pressure of the airbag 123 enters the pneumatic chamber 122 and pushes the impact rod 124 to move forward. The end of the impact rod 124 away from the pneumatic chamber 122 is close to the cleaning brush 119, and a rubber pad is provided at the end of the impact rod 124 away from the pneumatic chamber 122. The forward movement of the impact rod 124 will hit the cleaning brush 119, and the rubber pad at the front end of the impact rod 124 can prevent damage to the cleaning brush 119.

[0028] In this embodiment, based on the above-mentioned Embodiment 1, when the rotating shaft 3 rotates, it will also drive the collision block 121 to repeatedly squeeze the airbag 123. When the airbag 123 is squeezed, the air pressure inside it will enter the air pressure chamber 122 and push the impact rod 124 to move forward. When the impact rod 124 moves forward, it will hit the cleaning brush 119. When the collision block 121 leaves the airbag 123, the airbag 123 rebounds and the air pressure returns to the airbag 123, and the impact rod 124 moves backward to restore. By repeatedly hitting the cleaning brush 119 with the impact rod 124, the cleaning brush 119 is caused to vibrate, shaking off the dust on the cleaning brush 119, preventing too much dust from adhering to the cleaning brush 119 and affecting the subsequent cleaning effect, and the shaken-off dust will be sucked into the collection box 5 by the dust suction pipe 7.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
