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.

[0033] As recorded in the background art, the integrally designed blade commonly used in traditional graders has exposed some problems in practical applications. Due to the complex and changeable construction site environment, the blade is prone to wear, impact, and even breakage during long-term and high-intensity use. Especially when dealing with hard or filler containing a large amount of impurities, this situation is particularly prominent; the blade part of the existing paving device mostly adopts an integral design. When a part of the blade is damaged, it often requires the replacement of the whole, increasing the maintenance cost.

[0034] To solve this technical problem, the present utility model provides a road surface paving device.

[0035] Specifically, please refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6 , the road surface paving device specifically includes:

[0036] A shovel plate 1, on the back of the shovel plate 1, an installation frame 101 is installed. On the front of the installation frame 101, a plurality of blade bodies 2 are provided. Between the shovel plate 1 and the plurality of blade bodies 2, a fixing member is provided. The fixing member includes a plurality of second through holes 206 opened on the installation frame 101 and a plurality of first through holes 202 opened on the blade body 2. The inner wall of each first through hole 202 is inserted and connected with a limiting shaft 204. A limiting plate 203 is fixedly connected between the plurality of limiting shafts 204. One end of the limiting shaft 204 away from the limiting plate 203 passes through the second through hole 206, and a locking member is provided between the installation frame 101 and the limiting shaft 204.

[0037] In the road surface paving device provided by the present utility model, by providing a plurality of blade bodies 2, the blade adopts a segmented design. When one of the blade bodies 2 is damaged, only the damaged blade body 2 needs to be replaced, rather than the whole blade, significantly reducing the spare parts consumption and replacement cost, which is beneficial to use.

[0038] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings.

[0039] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments of the present utility model can be combined with each other.

[0040] It should be noted that like reference numerals and letters indicate like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0041] Example 1, please refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6 , a pavement paving device, including a shovel plate 1. An installation frame 101 is installed on the back of the shovel plate 1. A plurality of shovel blade bodies 2 are arranged on the front of the installation frame 101. A fixing member is arranged between the shovel plate 1 and the plurality of shovel blade bodies 2. The fixing member includes a plurality of second through holes 206 opened on the installation frame 101 and a plurality of first through holes 202 opened on the shovel blade bodies 2. A limiting shaft 204 is inserted through the inner wall of each first through hole 202. A limiting plate 203 is fixedly connected between the plurality of limiting shafts 204. One end of the limiting shaft 204 away from the limiting plate 203 passes through the second through hole 206, and a locking member is arranged between the installation frame 101 and the limiting shaft 204. By providing the plurality of shovel blade bodies 2 in this application, the shovel blade adopts a segmented design. When one of the shovel blade bodies 2 is damaged, only the damaged shovel blade body 2 needs to be replaced, rather than replacing the entire shovel blade, which significantly reduces the spare parts consumption and replacement cost and is beneficial to use.

[0042] Furthermore, as Figure 4 shown, a groove 201 is opened on the side of the shovel blade body 2 away from the installation frame 101. The limiting plate 203 is inserted into the inner wall of the groove 201. The setting of the groove 201 can prevent the limiting plate 203 from protruding.

[0043] Example 2, further optimize the pavement paving device provided in Example 1. Specifically, as Figure 2 、 Figure 4 and Figure 5 shown, the locking member includes a slot 205 opened on each limiting shaft 204. A limiting rod 207 is inserted through the inner walls of all the slots 205. The limiting rod 207 contacts the surface of the installation frame 101 away from the limiting plate 203. By inserting the limiting rod 207 into the slot 205, the limiting shaft 204 can be limited, and further the limiting plate 203 can be limited, so that the limiting plate 203 can limit the shovel blade body 2.

[0044] Furthermore, as Figure 2As shown, threads are provided at both ends of the limit rod 207, and fixing nuts 208 are threadedly connected to both ends of the limit rod 207. The fixing nuts 208 are in contact with the side surface of the shovel plate 1. The fixing nuts 208 can limit the limit rod 207. After removing the fixing nuts 208, pulling the limit rod 207 causes the limit rod 207 to separate from the slot 205, so that the limit shaft 204 can be separated from the second through hole 206 and the first through hole 202, and the corresponding shovel blade body 2 can be replaced.

[0045] Furthermore, two connecting members are installed on the back surface of the shovel plate 1, and a support member is arranged between the two connecting members.

[0046] Furthermore, as Figures 1 - 3 shown, the connecting members include two guide rails 310 installed on the back surface of the shovel plate 1. The outer surfaces of the two guide rails 310 are both slidably engaged with sliding seat holders 311. A support frame 309 is connected between the two sliding seat holders 311 by bolts. The support frame 309 limits the sliding seat holders 311, enabling the sliding seat holders 311 to be engaged with the guide rails 310, and the guide rails 310 and the sliding seat holders 311 can move relative to each other.

[0047] Furthermore, as Figures 1 - 3 shown, a connecting shaft 308 is provided on the support frame 309, and a support arm 307 is sleeved on the outer surface of the connecting shaft 308; a second hydraulic cylinder 5 is hinged between the support arm 307 and the support frame 309. A first hydraulic cylinder 4 is installed on the back surface of the shovel plate 1 and is located between the two guide rails 310. The first hydraulic cylinder 4 is connected to the support arm 307. Driving the shovel plate 1 to move by the first hydraulic cylinder 4 can adjust the horizontal position of the shovel plate 1, and driving the support frame 309 to rotate around the connecting shaft 308 by the second hydraulic cylinder 5 can adjust the angle of the shovel plate 1.

[0048] Embodiment 3 further optimizes the road surface paving device provided in Embodiment 1 or 2. Specifically, as Figures 1 - 2 shown, the support member includes a turntable 304. The support arm 307 is fixedly connected to the bottom of the turntable 304. The support arm 307 can support the support frame 309 through the connecting shaft 308.

[0049] Furthermore, as Figures 1 - 2 shown, a toothed ring 303 is fixedly installed on the turntable 304. The outer surface of the toothed ring 303 is slidably connected to a plurality of U-shaped seat holders 302. A support disk 301 is connected between the plurality of U-shaped seat holders 302. A fixed arm 3 is installed on the top of the support disk 301. The first through hole 202 is used to connect the support disk 301 and the turntable 304 together.

[0050] Furthermore, as Figure 1As shown, a motor 305 is installed on the top of the support disk 301. The output shaft of the motor 305 is fixedly connected to a gear 306. The gear 306 meshes with the toothed ring 303. The motor 305 can drive the turntable 304 to rotate through the gear 306 and the toothed ring 303, thereby adjusting the horizontal angle of the shovel plate 1.
