Description

Technical Field

[0001] This utility model is a small asphalt paving device, belonging to the field of road construction equipment. Background Technology

[0002] An asphalt paving device is a piece of equipment used in road construction, primarily for evenly spreading hot asphalt mixture onto the road surface to form a smooth road surface layer. Small asphalt paving devices are manually pushed and used to spread asphalt over small areas of the road surface, thus achieving road repair.

[0003] In the existing technology, hot asphalt mixture is transported to the construction site by transport vehicles and then poured into the hopper of the paver. An electrically driven auger spreader is installed at the discharge port of the hopper. The auger spreader consists of auger blades and an electric rotating shaft, which means that the device can only be used for asphalt paving under the support of electricity, thereby reducing the fault tolerance of the device and narrowing the scope of application of the device.

[0004] In summary, this utility model provides a small asphalt paving device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a small asphalt paving device to solve the problem mentioned in the background art that the device needs to be electrically driven for material feeding, which leads to a narrow range of device applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a small asphalt paving device, comprising an installation plate and a hopper, wherein wheels are fixedly installed around the bottom of the installation plate, the hopper extends between the top and bottom of the installation plate, and a discharge bin is connected to the bottom of the hopper. A rotating shaft extends through the front of the discharge bin, and two limiting rods extend through the other side of the top of the installation plate. A fixing frame is installed between the bottom ends of the two limiting rods, and an installation shaft is rotatably connected between the two sides of the inner wall of the fixing frame. A pressure roller is sleeved on the shaft surface of the installation shaft, one end of the installation shaft extends through the fixing frame and to the front of the fixing frame, and transmission gears are fixedly installed at the front ends of the installation shaft and the rotating shaft, respectively. A toothed chain meshes between the surfaces of the two transmission gears.

[0007] Furthermore, one end of the rotating shaft extends to the back of the inner wall of the discharge hopper, the rotating shaft is rotatably connected to the discharge hopper through a bearing, and a spiral blade is fixedly installed on the axial surface of the rotating shaft inside the discharge hopper, and the bottom of the discharge hopper is open.

[0008] Further, a fixed seat is fixedly installed on one side of the discharge bin. A push plate is fixedly connected to the bottom of the fixed seat in an inclined manner. The bottom of the push plate extends below the discharge bin. A right-angle frame is fixedly installed between one side of the push plate and the bottom of the fixed seat.

[0009] Further, both sides and the bottom of the fixed frame are in an open shape. The bottom of the surface of the pressure roller extends below the fixed frame.

[0010] Further, on both sides of the top of the inner wall of the fixed frame and at the top of the surface of the pressure roller, scraping plates are fixedly installed. And the two scraping plates are mirror-symmetric. The bottoms of the two scraping plates are in an "eight" shape and expand outwards.

[0011] Further, a limiting plate is commonly installed between the tops of the two limiting rods. The limiting rods are in contact with the mounting plate.

[0012] Further, two connecting rods are fixedly installed on one side of the top of the mounting plate. A push rod is fixedly installed between the tops of the two connecting rods.

[0013] The beneficial effects of the present utility model:

[0014] By rolling the pressure roller on the road surface, the rotation of the spiral blade can be driven through the transmission connection relationship among the tooth chain, the two transmission gears, the mounting shaft and the rotating shaft. When the device does not move, the rotation of the spiral blade can be stopped, and then during the process of laying asphalt material, when the device stops, the asphalt laying can be stopped. There is no need to start by electricity, so that the device can also carry out asphalt laying in an environment without power support, improving the fault tolerance rate of the device and expanding the application range of the device.

[0015] By rolling the pressure roller on the road surface, one transmission gear can be driven to rotate through the mounting shaft. One transmission gear drives another transmission gear to rotate through the tooth chain. The transmission gear drives the rotating shaft to rotate, and the rotating shaft drives the spiral blade to rotate. The spiral blade can block the bottom of the discharge bin. When the spiral blade rotates, the asphalt inside the discharge bin can be slowly taken out downwards. During the process of the device moving forward, the asphalt can be scattered and laid, avoiding the concentrated accumulation of asphalt on the road surface to be laid, reducing the resistance during the process of the push plate pushing the asphalt flat from left to right, making the device move more labor-saving, and effectively improving the use convenience of the small asphalt material paving device.

[0016] The bottoms of the two scraping plates are in an "eight" shape and expand outwards. When the pressure roller rotates clockwise or counterclockwise, the asphalt adhered to the surface of the pressure roller can be quickly scraped off by the scraping plates, ensuring the flatness when the pressure roller compresses the repaired position of the road surface.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-5This utility model provides a technical solution: a small asphalt paving device, including a mounting plate 1 and a hopper 3. Wheels 2 are fixedly installed around the bottom of the mounting plate 1. The hopper 3 passes between the top and bottom of the mounting plate 1, and a discharge bin 4 is connected to the bottom of the hopper 3. A rotating shaft 5 passes through the front of the discharge bin 4. Two limiting rods 6 pass through the other side of the top of the mounting plate 1. A fixing frame 7 is installed between the bottom ends of the two limiting rods 6. A mounting shaft 8 is rotatably connected between the two sides of the inner wall of the fixing frame 7. A pressure roller 9 is sleeved on the shaft surface of the mounting shaft 8. One end of the mounting shaft 8 passes through the fixing frame 7 and extends to the front of the fixing frame 7. Transmission gears 11 are fixedly installed at the front ends of both the mounting shaft 8 and the rotating shaft 5. A toothed chain 12 meshes between the surfaces of the two transmission gears 11. Both limiting rods 6 are in contact with the mounting plate 1. When the bottom of the pressure roller 9 passes over a steep slope, it can be flexibly adjusted up and down with the limiting rods 6 to ensure the pressure roller... The 9 rollers are always in contact with the road surface. One end of the rotating shaft 5 extends to the back of the inner wall of the discharge bin 4. The rotating shaft 5 is rotatably connected to the discharge bin 4 through a bearing. The rotating shaft 5 is fixedly installed with a spiral blade 19 inside the discharge bin 4. The spiral blade 19 can shield the bottom of the discharge bin 4. When the spiral blade 19 rotates, the asphalt inside the discharge bin 4 can be carried downward. The bottom of the discharge bin 4 is open. A fixed seat 13 is fixedly installed on one side of the discharge bin 4. A push plate 15 is fixedly connected to the bottom of the fixed seat 13 at an incline. The bottom of the push plate 15 extends to the bottom of the discharge bin 4. A right-angle frame 14 is fixedly installed between one side of the push plate 15 and the bottom of the fixed seat 13. When the whole device moves from left to right, the asphalt can be pushed flat from left to right by the push plate 15. The right-angle frame 14 can improve the installation stability of the push plate 15. The sides and bottom of the fixed frame 7 are open. The bottom of the roller surface of the pressure roller 9 extends to the bottom of the fixed frame 7.

[0026] Please see Figure 2-5 Scraper blades 10 are fixedly installed on both sides of the top of the inner wall of the fixed frame 7 and on the top of the roller surface of the pressure roller 9. The two scraper blades 10 are mirror symmetrical and the bottom of the two scraper blades 10 are shaped like an "eight" flaring outward. When the pressure roller 9 rotates clockwise or counterclockwise, the asphalt adhering to the surface of the pressure roller 9 can be quickly scraped off by the scraper blades 10 to ensure the flatness of the road surface repair position when the pressure roller 9 rolls the road. A limiting plate 16 is installed between the top ends of the two limiting rods 6. The limiting rods 6 are in contact with the mounting plate 1. The limiting plate 16 has a limiting function on the two limiting rods 6 to prevent the limiting rods 6 from detaching from the mounting plate 1. Two connecting rods 17 are fixedly installed on one side of the top of the mounting plate 1. A push rod 18 is fixedly installed between the top ends of the two connecting rods 17.

[0027] Specific implementation method: The whole device is pushed from left to right by the push rod 18, and the device is moved to the vicinity of the road surface to be paved. The asphalt material is introduced into the interior of the hopper 3 from top to bottom, and the asphalt material flows into the interior of the discharge bin 4. At the same time, the roller surface of the pressing roller 9 contacts the road surface. When the whole device is pushed from left to right, the pressing roller 9 rolls on the road surface, so that a transmission gear 11 can be driven to rotate by the mounting shaft 8. One transmission gear 11 drives another transmission gear 11 to rotate through the toothed chain 12. The transmission gear 11 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the spiral blade 19 to rotate. The spiral blade 19 can block the bottom of the discharge bin 4. When the spiral blade 19 rotates, the asphalt inside the discharge bin 4 can be slowly taken out downward. During the process of the device moving forward, the asphalt can be scattered and paved, avoiding the concentrated accumulation of asphalt on the road surface to be paved, reducing the resistance during the process of the push plate 15 pushing the asphalt flat from left to right, making the device move more labor-saving, and effectively improving the use convenience of the small asphalt material paving device.

[0028] When the device is moving, it can drive the pressing roller 9 to roll on the road surface. Then, through the transmission connection relationship among the toothed chain 12, the two transmission gears 11, the mounting shaft 8 and the rotating shaft 5, the spiral blade 19 can be driven to rotate for feeding. When the device is not moving, the spiral blade 19 can be made to stop rotating. Then, during the process of paving the asphalt material, when the device stops, the asphalt paving stops. There is no need to start by electricity, so that the device can also carry out asphalt paving in an environment without power support, improving the use fault tolerance rate of the device and expanding the use range of the device.

[0029] The bottoms of the two scraping plates 10 are in an outward-expanded shape like the Chinese character "八". When the pressing roller 9 rotates clockwise or counterclockwise, the asphalt adhered to the surface of the pressing roller 9 can be quickly scraped off by the scraping plates 10, ensuring the flatness when the pressing roller 9 compresses the repaired position of the road surface.

[0030] In addition, it should be understood that although this specification is described according to the implementation modes, not each implementation mode only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
