[0029] Example 1

[0030] See also Figure 1-3 As shown, this embodiment is an asphalt paver for road maintenance, comprising:

[0031] The paver assembly 1 includes a paver housing 11;

[0032] The movable assembly 2 comprises a material discharge chute 21 fixedly connected to the central position of the bottom end of the paving machine housing 11, an inclined bucket 22 fixedly connected to the front end position inside the material discharge chute 21, a hollow groove 23 opened at the rear end position inside the material discharge chute 21, a slider 24 placed inside the hollow groove 23, a bucket 25 fixedly connected to the inner side of the slider 24, and an electric push rod 26 fixedly connected to the rear side of the slider 24;

[0033] The feed chute 21 is used to place the asphalt discharged from the barrel 12, the inclined bucket 22 is used to make the asphalt flow downward, the hollow groove 23 is used to place the slider 24, the slider 24 is used to drive the bucket 25 to move inside the feed chute 21, and the electric push rod 26 is used to drive the slider 24 to move;

[0034] The paving machine assembly 1 further includes a material bucket 12 fixedly connected to the upper end of the paving machine housing 11, a handle 13 fixedly connected to the upper end of the rear side of the paving machine housing 11, a pressure roller 14 rotatably connected to the rear side of the inside of the paving machine housing 11, a rear wheel 15 rotatably connected to the rear end of the outside of the paving machine housing 11, and a front wheel 16 rotatably connected to the front side of the bottom end of the paving machine housing 11;

[0035] The material barrel 12 is used to place asphalt and keep it warm, the handle 13 is used to push the paver housing 11, the pressure roller 14 is used to flatten the spread asphalt, and the rear wheel 15 and the front wheel 16 are used to drive the paver housing 11 to move;

[0036] The lower chute 21 is connected to the inside of the barrel 12, and the bottom end of the inclined bucket 22 is flush with the bottom end of the bucket 25;

[0037] When the bucket 25 moves forward, the asphalt can be driven forward. When the front end of the bucket 25 is flush with the front end of the inclined bucket 22, the bottom end of the feed chute 21 can be closed.

[0038] The electric push rod 26 is located inside the hollow groove 23, and the hollow groove 23 is opened relative to the slider 24;

[0039] When the electric push rod 26 extends forward, it can drive the slider 24 to move forward inside the hollow groove 23;

[0040] Working principle: When paving asphalt, the front wheel 16 and the rear wheel 15 are moved by pushing the handle 13, so that the paver housing 11 is moved to the road where asphalt needs to be paved, and the electric push rod 26 is started to shorten the electric push rod 26 backward. The shortening of the electric push rod 26 drives the slider 24 to move backward inside the hollow groove 23, so that the slider 24 drives the bucket 25 to move backward, so that the bottom end of the discharge chute 21 is opened, and the asphalt enters the discharge chute 21 from the inside of the barrel 12 and flows onto the road. When the asphalt is paved, the electric push rod 26 is started again to extend the electric push rod 26 forward. The extension of the electric push rod 26 forward drives the slider 24 to move forward inside the hollow groove 23, so that the slider 24 drives the bucket 25 to move forward, and the bucket 25 shovels the excess asphalt forward. When the front end of the bucket 25 moves to contact the rear end of the inclined bucket 22, the excess asphalt can be shoveled into the inside of the discharge chute 21.

[0041] Example 2

[0042] See also Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0043] A fixing assembly 3, fixedly connected to the front side of the bottom end of the paving machine housing 11;

[0044] The fixing assembly 3 includes a first support block 31 fixedly connected to both sides of the bottom end of the paving machine housing 11, a second support block 32 fixedly connected to the center of the front end of the paving machine housing 11, and a baffle 33 fixedly connected to the outer sides of the first support block 31 and the second support block 32;

[0045] The first support block 31 is used to support the inner side of the rear end of the baffle 33, and the second support block 32 is used to support the inner side of the front end of the baffle 33. The bottom end of the baffle 33 is in contact with the road.

[0046] The baffle 33 is located at the front end of the front wheel 16, and the baffle 33 is in a “>” shape;

[0047] When the paver housing 11 moves forward, the baffle 33 can be driven to move forward;

[0048] Working principle: When the paver shell 11 is moved on the road, the baffle 33 is always located at the front end of the front wheel 16. When the paver shell 11 is moved, the baffle 33 moves with the paver shell 11, so that impurities on the road at the front end of the paver shell 11 slide along the baffle 33 to both sides.
