[0001] This utility model relates to the field of asphalt construction technology, and in particular to an asphalt paver. Background Technology
[0002] When laying asphalt roads, pavers are generally used to lay the asphalt onto the road surface. Commonly used pavers have the following defects: the asphalt is not insulated during transportation and is not in a fluid state due to mixing alone, which easily leads to solidification and affects the paving of the asphalt.

[0005] Preferably, the machine body is provided with multiple wheels at the bottom.
[0006] Preferably, the machine body is provided with a chute on the top, and the material frame is provided with a slide rod that slides in the chute on the side.
[0007] Preferably, the material frame extends from the side with a limiting block, and the first hydraulic cylinder pushes the bracket, which in turn pushes the limiting block to move the material frame on the machine body.
[0008] Preferably, there are two augers with opposite spiral directions of the blades, and a motor is provided at the end of the material frame to drive the augers to rotate.
[0009] This utility model has a simple and ingenious structure and is easy to use. By setting a heating device inside the auger, it can stir and keep the asphalt warm, preventing the asphalt from solidifying; and it can speed up the asphalt feeding speed during paving, improving construction efficiency.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0015] Depend on Figures 1 to 4 As can be seen, an asphalt paver includes a body 1, a material frame 2 is provided on the top of the body 1, a material outlet 3 is provided at the end of the material frame 2, the material frame 2 can move on the body 1, and the material outlet 3 is blocked after the material frame 2 moves on the body 1, a first hydraulic cylinder 4 is provided on the top of the body 1, a bracket 5 is provided at the end of the telescopic rod of the first hydraulic cylinder 4, a second hydraulic cylinder 6 connected to the material frame 2 is provided on the bracket 5, and an auger 7 is rotatably arranged inside the material frame 2. The auger 7 is a hollow structure and a heating device is provided inside the auger 7.
[0016] In practical use, this utility model
[0017] First, move the material frame 2 to block the discharge port 3, pour the asphalt into the material frame 2, and start the auger 7. The heating device inside the auger 7 heats and keeps the asphalt warm to prevent it from solidifying due to cooling. At the same time, the auger 7 can stir the asphalt, making it flow to complete heat exchange and ensure the overall temperature of the asphalt, thereby preventing solidification.
[0018] During paving, the material frame 2 moves, causing the discharge port 3 to open, and asphalt falls from the discharge port 3 onto the road surface. At this time, the auger 7 can push the asphalt towards the discharge port 3, accelerating the paving speed of the asphalt.
[0019] Multiple wheels 8 are provided under the machine body 1 to facilitate moving the machine body 1 to the paving position.
[0020] The machine body 1 is provided with a slide groove 9 on the top, and the material frame 2 is provided with a slide rod 10 that slides in the slide groove 9 on the side. A limit block 11 extends from the side of the material frame 2. The first hydraulic cylinder 4 pushes the bracket 5, and the bracket 5 pushes the limit block 11 to make the material frame 2 move on the machine body 1.
[0021] When the material frame 2 moves, it is limited by the cooperation of the slide rod 10 and the slide groove 9. When the slide rod 10 is at the extreme positions at both ends of the slide groove 9, the discharge port 3 is in the blocked and open state. When the discharge port 3 is opened to the maximum state, the second hydraulic cylinder 6 extends to make the material frame 2 rotate, and the discharge port 3 is at a low position, which is conducive to the discharge of asphalt.
[0022] The second hydraulic cylinder 6 is rotatably mounted on the bracket 5, so that it is unrestricted when pushing the material frame 2 to rotate.
[0023] The end of the machine body 1 can cooperate with the end of the material frame 2 to ensure complete sealing of the discharge port 3 and prevent asphalt leakage.
[0024] Two augers 7 are provided with their blades spiraling in opposite directions. A motor 12 is provided at the end of the material frame 2 to drive the augers 7 to rotate. When the two augers 7 rotate, the asphalt flows in the material frame 2, allowing more asphalt to come into contact with the augers 7, thereby achieving heating and heat preservation.
[0025] Compared with the prior art, this utility model has the following advantages: a heating device is set inside the auger to heat the asphalt from the inside, and the asphalt is made to flow by stirring, so as to ensure the overall temperature of the asphalt and avoid solidification.
