The asphalt paving device 100 for road construction includes a body 10, a traveling mechanism 11, a feeding mechanism 12, a feeding mechanism 13, a driving motor (not shown in the figure), an auger 14 and a paving mechanism 16.

[0033] The body 10 is the main frame of the asphalt paving device 100 for road construction, and can be regarded as the main structure of the asphalt paving device 100 for road construction.

[0034] The traveling mechanism 11 is provided on the machine body 10 to drive the machine body 10 to move along a specified direction X. For example, the traveling mechanism 11 can be any type of crawler traveling mechanism or wheel traveling mechanism. It should be noted that the above-mentioned "specified direction X" can be understood as the moving direction of the asphalt paving device 100 for road construction.

[0035] The feeding mechanism 12 is a mechanism of the asphalt paving device 100 for road construction for receiving foreign materials. The feeding mechanism 12 includes a feeding hopper 121 provided on the machine body 10. The feeding hopper 121 is a specific structure for receiving foreign materials.

[0036] The feeding mechanism 13 is a mechanism of the asphalt paving device 100 for road construction used to transport the material in the feeding mechanism 12 to the location of the auger 14. The feeding mechanism 13 includes a discharge hopper 131 provided on the machine body 10. The feeding mechanism 13 is used to transport the material in the feeding hopper 121 to the discharge hopper 131 and discharge it. For example, the feeding mechanism 13 may include a screw conveyor (not shown in the figure), the feeding end of the screw conveyor is located in the feeding hopper 121, and the discharging end is located in the discharge hopper 131. The screw conveyor is used to transport the material in the feeding hopper 121 to the discharge hopper 131, so that the material can be discharged from the discharge hopper 131.

[0037] The driving motor is disposed on the machine body 10 , and specifically, the output shaft of the driving motor is disposed perpendicularly to the designated direction X. The driving motor is used to drive the auger 14 to rotate to realize the transportation of materials.

[0038] The auger 14 is connected to the driving motor, and is used to receive the materials discharged from the discharge hopper 131 and transport the materials to both sides of the machine body 10. It should be noted that the above-mentioned "both sides of the machine body 10" specifically refers to the left and right sides of the machine body 10 relative to its own forward direction (i.e., the specified direction X), and the line connecting the two sides of the machine body 10 is approximately perpendicular to the specified direction X.

[0039] The paving mechanism 16 is disposed on the machine body 10, and is used to spread and flatten the material discharged by the auger 14 to realize the asphalt paving operation of the asphalt paving device 100 for road construction. In some embodiments, the paving mechanism 16 includes a paver and a roller (neither of which is shown in the figure) disposed on the machine body 10, the paver is used to evenly pave the material on the surface of the construction road, and the roller is used to compact the material on the surface of the construction road.

[0040] See also Figure 2-Figure 4 The auger 14 includes a connecting shaft 141, a movable shaft 142, a push-pull assembly 143, an auger blade 144, an auxiliary blade 145, a first connecting member 146 (see Figure 5 and Figure 6 ) and a stop bar 147.

[0041] The connecting shaft 141 is roughly in the shape of a round rod, and is connected to the driving motor. The connecting shaft 141 is coaxially arranged with the output shaft of the driving motor. The auger blade 144 is spirally arranged on the outer peripheral wall of the connecting shaft 141 and extends to the end of the connecting shaft 141. The auger blade 144 can be welded to the connecting shaft 141, or fixedly connected to the connecting shaft 141 by fasteners such as screws and bolts. An accommodating chamber 1414 is provided inside the connecting shaft 141, and the push-pull assembly 143 and the movable shaft 142 are both arranged in the accommodating chamber 1414. The push-pull assembly 143 is connected to the movable shaft 142 to drive the movable shaft 142 to move along the axial direction of the connecting shaft 141. The connecting shaft 141 is also provided with a plurality of sliding grooves 1415 that are connected to the accommodating chamber 1414, and the plurality of sliding grooves 1415 extend along the axial direction of the connecting shaft 141. The blocking rod 147 is generally in the shape of a long strip. The blocking rod 147 is located on the outer side wall of the connecting shaft 141 and blocks the sliding groove 1415. The blocking rod 147 is connected to the first connecting member 146 (see Figure 5 and Figure 6 ) is connected to the movable shaft 142, and the first connecting member 146 is inserted into the sliding groove 1415. The first connecting member 146 can be a fastener such as a screw or a bolt, which is used to achieve a fixed connection between the blocking rod 147 and the movable shaft 142. The auxiliary blade 145 is connected to the blocking rod 147.

[0042] Through the above arrangement, when the asphalt paving device 100 for road construction is working, the material is first placed in the feed hopper 121 for temporary storage, and the feeding structure 13 continuously transports the material in the feed hopper 121 to the discharge hopper 131 and discharges it, and the material discharged from the discharge hopper 131 falls onto the connecting shaft 141 of the auger 14. Since the driving motor drives the connecting shaft 141 to rotate continuously, the connecting shaft 141 drives the auger blades 144 to rotate and transport the materials to the two ends of the connecting shaft 141. At the same time, the push-pull component 143 can drive the movable shaft 142 and the auxiliary blades 145 to move toward the ends of the connecting shaft 141, so that the auxiliary blades 145 can quickly push the materials to the two ends of the connecting shaft 141, so as to achieve the effect of increasing the speed of transporting the materials on the auger 14 to its own two ends; when the movable shaft 142 moves to the extreme position close to the end of the connecting shaft 141, the push-pull component 143 drives the movable shaft 142 to move in the direction away from the end of the connecting shaft 141. The above process is repeated continuously, which can increase the speed of transporting the materials outside the connecting shaft 141 to the two ends of the auger 14. After the auger 14 transports the material to both sides of the machine body 10, since the traveling mechanism 11 drives the machine body 10 to move along the specified direction X, the machine body 10 will drive the paving mechanism 16 to pass through the material discharged by the auger 14, thereby evenly spreading the material discharged by the auger 14 on the surface of the construction road to realize the asphalt paving operation on the construction road.

[0043] To sum up, the auger 14 of the above-mentioned asphalt paving device 100 for road construction can not only transport materials to both sides of the body 10 through the auger blades 144, but also drive the auxiliary blades 145 through the push-pull assembly 143 to push the materials on the connecting shaft 141 to the two ends of the connecting shaft 141, thereby accelerating the rate of transporting the materials to both sides of the body 10. Therefore, the above-mentioned asphalt paving device 100 for road construction has the beneficial effects of high paving efficiency and uniform paving during the process of paving asphalt.

[0044] See also Figure 2-Figure 4In some embodiments, the connecting shaft 141 has a first end 1411, a second end 1412 and a central portion 1413.

It should be noted that the central portion 1413 is at least a part of the structure of the connecting shaft 141 located in the middle position of itself, and the midpoint of the connecting shaft 141 is located within the central portion 1413; “the central portion 1413 is correspondingly arranged with the discharge hopper 131” means that the material discharged from the discharge hopper 131 can fall on the central portion 1413, so that the auger 14 can transport the material discharged from the discharge hopper 131 to both ends of the machine body 10. The auger blade 144 includes a first auger blade 1441 and a second auger blade 1442. One end of the first auger blade 1441 is located at the center 1413, and the other end is located at the first end 1411. One end of the second auger blade 1442 is located at the center 1413, and the other end is located at the second end 1412. The spiral directions of the first auger blade 1441 and the second auger blade 1442 are opposite, so as to achieve the effect of transporting the material located at the center 1413 to the two ends of the auger 14 (both sides of the body 10).

[0045] Through the above arrangement, when the driving motor drives the connecting shaft 141 to rotate, the first auger blade 1441 and the second auger blade 1442 can transport the material located in the center portion 1413 to the first end 1411 and the second end 1412 respectively, thereby transporting the material discharged from the discharge hopper 131 to both sides of the machine body 10.

The push-pull assembly 143 is used to drive the movable shaft 142 to move axially along the connecting shaft 141. Specifically, the first push-pull assembly 1431 is used to drive the first movable shaft 1421 to move axially along the connecting shaft 141, and the second push-pull assembly 1432 is used to drive the second movable shaft 1422 to move axially along the connecting shaft 141. The blocking rod 147 includes a first blocking rod 1471 and a second blocking rod 1472. The first blocking rod 1471 is connected to the first movable shaft 1421 through a first connecting member 146, and the second blocking rod 1472 is connected to the second movable shaft 1422 through the first connecting member 146. The first connecting member 146 is inserted into the sliding groove 1415. The first connecting member 146 can be a fastener such as a screw or a bolt, which is used to realize the fixed connection between the first blocking rod 1471 and the first movable shaft 1421, and also used to realize the fixed connection between the second blocking rod 1472 and the second movable shaft 1422.

The first auxiliary blade 1451 is connected to the first blocking rod 1471, and the second auxiliary blade 1452 is connected to the second blocking rod 1472.

[0047] Through the above arrangement, when the asphalt paving device 100 for road construction is working, the driving motor drives the connecting shaft 141 to rotate continuously, and the first auger blade 1441 and the second auger blade 1442 can transport the material located in the center portion 1413 to the first end 1411 and the second end 1412 respectively, thereby realizing the transportation of the material discharged from the discharge hopper 131 to both sides of the machine body 10. In the above process, the first push-pull component 1431 drives the first movable shaft 1421 to drive the first baffle rod 1471 and the first auxiliary blade 1451 to move toward the direction close to the first end 1411, thereby accelerating the transportation rate of the material on the connecting shaft 141 to the first end 1411. When the first movable shaft 1421 moves to the limit position in the direction close to the first end 1411, the first push-pull component 1431 drives the first movable shaft 1421 to drive the first baffle rod 1471 and the first auxiliary blade 1451 to move toward the position close to the center portion 1413 to the limit position. Then the first push-pull component 1431 drives the first movable shaft 1421 to drive the first baffle rod 1471 and the first auxiliary blade 1451 to move toward the direction close to the first end 1411 to the limit position to transport the material to the first end 1411. The above process is repeated continuously, thereby increasing the transportation rate of the material on the auger 14 from the center portion 1413 to the first end 1411. Rate; similarly, the second push-pull component 1432 drives the second movable shaft 1422 to drive the second baffle rod 1472 and the second auxiliary blade 1452 to move toward the second end 1412, thereby accelerating the transportation rate of the material on the connecting shaft 141 to the second end 1412.

[0050] See also Figure 2-Figure 6In some embodiments, the auger 14 further includes a plurality of first connection blocks 148 and a plurality of second connection members 150. The number of the first connection blocks 148 is the same as the number of the first auxiliary blades 1451. The plurality of first connection blocks 148 are connected to the plurality of first auxiliary blades 1451 in a one-to-one correspondence. The first connection blocks 148 and the first auxiliary blades 1451 can be connected in any manner such as integral molding connection, welding connection or adhesive connection. The first connection block 148 is detachably connected to the first baffle 1471 through the second connection member 150. For example, the second connection member 150 can be a fastener such as a screw or a bolt. Through the above arrangement, the plurality of second connection members 150 realizes the detachable connection of the plurality of first auxiliary blades 1451 and the first baffle 1471 separately. Therefore, when a first auxiliary blade 1451 has a fault such as wear after long-term use, the staff can disassemble and replace the faulty first auxiliary blade 1451 separately, thereby reducing material waste and reducing the use cost. The auger 14 further includes a plurality of second connection blocks 149 and a plurality of third connection members 151. The number of the second connection blocks 149 is the same as the number of the second auxiliary blades 1452, and the plurality of second connection blocks 149 are connected to the plurality of second auxiliary blades 1452 in a one-to-one correspondence.

[0051] See also Figure 1 , Figure 2 , Figure 3 and Figure 7In some embodiments, the first auxiliary blade 1451 is eccentrically arranged on the outer peripheral wall of the connecting shaft 141, so that the first auxiliary blade 1451 will collide with the hopper 131 in the process of following the rotation of the connecting shaft 141. It should be noted that the above-mentioned "the first auxiliary blade 1451 is eccentrically arranged on the outer peripheral wall of the connecting shaft 141" means that there are at least two reference points on the side of the first auxiliary blade 1451 away from the connecting shaft 141, and the distances from these two reference points to the central axis of the connecting shaft 141 are different. Specifically, the above-mentioned two reference points can be the two end points of the side of the first auxiliary blade 1451 away from the connecting shaft 141, and the distance from one end point (end point A) to the central axis of the connecting shaft 141 is smaller than the distance from the other end point (end point B) to the central axis of the connecting shaft 141. The distance from the center axis of the connecting shaft 141 is greater than the distance from the center axis of the discharge hopper 131 to the connecting shaft 141. Therefore, during the rotation of the first auxiliary blade 1451, when the end point B rotates to the position of the discharge hopper 131, it will collide with the discharge hopper 131, while the end point A will not collide with the discharge hopper 131 when it rotates to the position of the discharge hopper 131, so that during the rotation of the auger 14, the first auxiliary blade 1451 will intermittently collide with the discharge hopper 131. The discharge hopper 131 can be a square cylindrical structure made of a plurality of metal sheets enclosed and spliced. When the first auxiliary blade 1451 collides with the discharge hopper 131, the metal sheets constituting the discharge hopper 131 will vibrate, thereby vibrating and shaking out the material blocked in the discharge hopper 131.

[0052] Through the above arrangement, during the rotation of the auger 14, the first auxiliary blade 1451 will rotate and at least part of the structure of the first auxiliary blade 1451 will intermittently collide with the discharge hopper 131, thereby vibrating and shaking out the material blocked in the discharge hopper 131, so as to improve the discharge efficiency of the discharge hopper 131, thereby improving the material transportation efficiency of the auger 14.

It should be noted that the above-mentioned "the second auxiliary blade 1452 is eccentrically arranged on the outer peripheral wall of the connecting shaft 141" means that there are at least two reference points on the side of the second auxiliary blade 1452 away from the connecting shaft 141, and the distances from these two reference points to the central axis of the connecting shaft 141 are different. Specifically, the above-mentioned two reference points can be the two end points of the side of the second auxiliary blade 1452 away from the connecting shaft 141, and the distance from one end point (end point C) to the central axis of the connecting shaft 141 is smaller than the distance from the other end point (end point D) to the central axis of the connecting shaft 141. The distance from the end point D to the central axis of the connecting shaft 141 is greater than the distance from the discharge hopper 131 to the central axis of the connecting shaft 141. Therefore, during the rotation of the second auxiliary blade 1452, when the end point D rotates to the position of the discharge hopper 131, it will collide with the discharge hopper 131, while the end point A will not collide with the discharge hopper 131 when it rotates to the position of the discharge hopper 131, so that during the rotation of the auger 14, the second auxiliary blade 1452 will intermittently collide with the discharge hopper 131. The discharge hopper 131 can be a square cylindrical structure made of a plurality of metal sheets enclosed and spliced. When the second auxiliary blade 1452 collides with the discharge hopper 131, the metal sheets constituting the discharge hopper 131 will vibrate, thereby vibrating and shaking out the material blocked in the discharge hopper 131.
