Detailed Embodiments

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the 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 shall fall within the protection scope of the present utility model.

[0015] Detailed Embodiment 1: As Figures 1-5As shown in the figure, this embodiment describes a concrete pavement paving device, including a fixing plate 1; there are two fixing plates 1, and a paving roller 8 is arranged between the two fixing plates 1; a shaft rod is fixedly connected to the side surface of the paving roller 8, and the shaft rod is connected to the fixing plate 1 through a bearing; a motor bracket 3 is fixedly connected to the side surface of the fixing plate 1, a motor 4 is fixedly connected inside the motor bracket 3, and the output shaft of the motor 4 is fixedly connected to the shaft rod; a traveling wheel 2 is arranged at a position near the bottom outside the fixing plate 1; a conical groove 9 with a hollow bottom is arranged above the paving roller 8; a rotating shaft 92 is fixedly connected to the side surface of the conical groove 9, the rotating shaft 92 is connected to the inner wall of the fixing plate 1 through a bearing, and a transmission rod 91 is also fixedly connected to the side surface of the conical groove 9; an arc-shaped groove 10 that slidably cooperates with the transmission rod 91 is arranged on the fixing plate 1; a horizontal sliding groove 11 is arranged on the fixing plate 1; a slider 71 that slidably cooperates with the sliding groove 11 is arranged in the sliding groove 11; one end of the slider 71 between the two fixing plates 1 is fixedly connected to a push plate 7; a connecting plate 5 is also fixedly connected to the outer side surface of the fixing plate 1; the side surface of the connecting plate 5 is fixedly connected to the fixed end of a hydraulic cylinder 6; the free end of the hydraulic cylinder 6 is fixedly connected to the slider 71. The concrete pavement is subjected to a secondary leveling operation during one forward movement through the push plate 7 and the paving roller 8, ensuring that the road surface is flat and smooth.

[0016] When the transmission rod 91 is located at the center of the arc-shaped groove 10, there are gaps between the lower ends of the two side plates of the conical groove 9 in the traveling direction of the paving roller 8 and the paving roller 8. This enables the conical groove 9 to rotate around the rotating shaft 92, and further enables the side plates of the conical groove 9 to contact the outer circular surface of the paving roller 8, forming a cavity for storing concrete.

[0017] When the transmission rod 91 moves to one end of the arc-shaped groove 10, the lower end of one side plate of the conical groove 9 in the traveling direction of the paving roller 8 contacts the outer circular surface of the paving roller 8.

[0018] The bottom end of the side of the push plate 7 close to the paving roller 8 is provided with an inclined surface, and a through hole 72 vertically penetrating the push plate 7 is arranged on the side of the push plate 7 close to the paving roller 8. The concrete adhered to the paving roller 8 is scraped off by the push plate 7 and stored at the lower end of the inclined surface to fill small-volume depressions on the road surface.

[0019] When the hydraulic cylinder 6 extends to the longest, the end of the push plate 7 with the through hole 72 contacts the outer circular surface of the paving roller 8.

[0020] A plurality of the through holes 72 are arranged at intervals.

[0021] The lower end plane of the push plate 7 is on the same horizontal plane as the lowest point of the paving roller 8.

[0022] The working principle of the utility model is as follows: when using this device, place the push plate 7 behind the paving roller 8 in the advancing direction of this device, and then start the hydraulic cylinder 6. The hydraulic cylinder 6 drives the slider 71 to move along the chute 11, thereby adjusting the side of the push plate 7 provided with the perforations 72 to abut against the outer circumferential surface of the paving roller 8, and pushing the transmission rod 91 to one end of the arc-shaped groove 10, so that the side plate of the tapered groove 9 close to the advancing direction of this device abuts tightly against the outer circumferential surface of the paving roller 8, and a gap is left between the other side plate and the paving roller 8 (as shown in the state of Figure 1 ). Then start the motor 4. The motor 4 drives the paving roller 8 to rotate, and drives this device to move through the movement of the traveling wheels 2. During the movement, the paving roller 8 rotates to push the excess concrete forward and level the surface. Part of the concrete adheres to the paving roller 8 and rotates with it. When the adhered concrete contacts the push plate 7, part of the concrete is blocked by the push plate 7 and falls back onto the concrete surface again. The other part passes through the perforations 72 and continues to move with the paving roller 8. After moving through the highest point of the paving roller 8, it contacts the side surface of the tapered groove 9 and is blocked by the side plate of the tapered groove 9, staying in the space enclosed by the tapered groove 9 and the paving roller 8, cleaning and smoothing the outer circumferential surface of the paving roller 8, avoiding the depression of the concrete surface when the paving roller 8 works. As this device moves, the push plate 7 also moves accordingly, performing secondary leveling on the concrete surface. The concrete scraped off by the push plate 7 stays in the inclined plane on the side of the push plate 7 close to the paving roller 8. When passing through the small-volume depression position of the concrete plane, it fills the depression, and then is leveled by the push plate 7, saving the time for transporting concrete to fill the depression;

[0023] When encountering a large-volume depression, move this device in the reverse direction so that the paving roller 8 moves to the rear of the large-volume depression. Then push the transmission rod 91 to the other end, and the tapered groove 9 rotates accordingly, and a gap is left between the side plate of the tapered groove 9 and the paving roller 8 for the concrete inside the tapered groove 9 to slide down. After the concrete slides down onto the plane, move the tapered groove 9 to its original position, and then move this device forward. The paving roller 8 and the push plate 7 push the slid concrete to the depression to fill it;

[0024] During paving, workers can also use tools to scoop up the concrete that is about to overflow the road surface with the tools and put it into the tapered groove 9 for filling depressions or filling it to the end of the concrete road surface to avoid the concrete overflowing to both sides of the road and causing waste.

[0025] If there is still concrete remaining in the tapered groove 9 after moving to the end of the concrete, the transmission rod 91 can be pushed to fill the concrete in the tapered groove 9 at the end of the concrete road surface, which is convenient for using it together with the concrete transported by the next batch of concrete tank trucks, and avoiding the drying and solidification of the concrete in the tapered groove 9, which affects the use of this device.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other forms of devices without departing from the spirit or basic characteristics of the present utility model.
