[0016] The following is combined with Figure 1-10 This application is described in further detail.

[0017] The present application embodiment discloses a water conservancy construction rolling device. Figure 1 As shown, the water conservancy construction rolling device includes a cart 1, on which a rolling roller 4, a compacting unit 3 and a leveling unit 2 are arranged in sequence along the moving direction of the cart 1, and the rolling roller 4 is arranged horizontally and is rotatably connected to the cart 1 around its own axis. When the cart 1 moves on the ground, the rolling roller 4 will roll on the material on the ground, thereby rolling the leveled and compacted material.

[0018] like Figure 2 and Figure 3As shown, the leveling unit 2 includes a leveling frame 21 installed on the trolley 1, the projection of the leveling frame 21 on the horizontal plane is arranged in a "U" shape, and the U-shaped opening of the leveling frame 21 faces the front of the trolley 1; the leveling frame 21 is slidably fitted with a scraper plate group 22 in a horizontal direction perpendicular to the moving direction of the trolley 1, and the scraper plate group 22 is threadedly fitted with a reciprocating screw 23, the axial direction of the reciprocating screw 23 is the same as the sliding direction of the scraper plate group 22, and the reciprocating screw 23 is rotatable around its own axis and is connected to the leveling frame 21 and is connected to the rolling roller 4 through a belt drive.

[0019] During the process of the rolling roller 4 rolling the material, the rolling roller 4 will drive the reciprocating screw 23 to rotate through the belt transmission, and the reciprocating screw 23 will drive the scraper plate group 22 to circulate. The scraper plate group 22 will scrape the material back and forth during the movement, so that the material at the protruding parts of the material layer can fill the depressed parts of the material layer, thereby leveling the material; that is, through the movement of the cart 1, the present application can realize the simultaneous leveling process and the rolling process, thereby improving the construction efficiency of the water conservancy construction.

[0020] like Figure 3 and Figure 4 As shown, the scraper plate group 22 includes a sleeve 221 for threaded cooperation with the reciprocating screw rod 23, a sliding frame 222 is installed on the sleeve 221, two limit rods 223 are slidably penetrated on the sliding frame 222, and the limit rods 223 are installed on the leveling frame 21, so that the sliding frame 222 can only slide in a horizontal direction perpendicular to the moving direction of the cart 1; the leveling frame 21 is provided with a slide groove 211 and a limit groove 212, one end of the sliding frame 222 is slidably embedded in the slide groove 211, and the rotating shaft 225 is slidably embedded in the limit groove 212, so as to further improve the stability of the sliding frame 222 during the sliding process.

[0021] like Figure 4 and Figure 5 As shown, a magnetic cylinder 224 extending along the travel direction of the cart 1 is installed on the sliding frame 222, and a rotating shaft 225 is rotatably embedded in the magnetic cylinder 224, and a scraper 226 is installed on the rotating shaft 225. In the process of the reciprocating screw 23 driving the sleeve 221 to circulate, the sleeve 221 will drive the rotating shaft 225 and the scraper 226 to move through the sliding frame 222 and the magnetic cylinder 224, so that the scraper 226 can level the material; the adsorption force of the magnetic cylinder 224 on the rotating shaft 225 will cause the scraper 226 to remain stable during the leveling process; in addition, the rear end of the leveling frame 21 and the magnetic cylinder 224 will be clamped together on the scraper 226, so that the scraper 226 is not easy to shake, further improving the stability of the scraper 226 during the leveling process.

[0022] like Figure 2 and Figure 3As shown, it is worth noting that the lower surface of the scraper 226 is 1-3 cm higher than the lowest point of the rolling roller 4, thereby reserving space for the compaction of the compaction unit 3 and the rolling of the rolling roller 4; the lower surface of the rear end of the leveling frame 21 is flush with the lower surface of the scraper 226, so that the leveling frame 21 will not damage the material leveled by the scraper 226 during the movement, and the material higher than the leveled material layer will be pushed forward by the rear end of the leveling frame 21 to fill the depression in the material layer in front.

[0023] like Figure 4 and Figure 6 As shown, the leveling frame 21 is provided with a flip assembly 24, which includes a first rack 241 and a second rack 242 respectively mounted on the left and right ends of the leveling frame 21, and a first half gear 227 and a second half gear 228 are fixedly sleeved on the rotating shaft 225.

[0024] During the circular motion of the rotating shaft 225, if the rotating shaft 225 moves to the left end of the leveling frame 21, the first half gear 227 can mesh with the first rack 241 and rotate 180 degrees on the first gear. At this time, the rotating shaft 225 has driven the scraper 226 to flip 180 degrees around the axis of the rotating shaft 225. The upper end of the scraper 226 will first flip away from the center of the leveling frame 21 and then flip closer to the center of the leveling frame 21, so that the material pushed to the left end of the leveling frame 21 by the lower end of the scraper 226 is between the scraper 226 and the leveling frame 2 1, to prevent this part of the material from being separated from the inner side of the leveling frame 21, so that this part of the material can fill the concave part of the material layer in front; then the first half gear 227 will be separated from the first rack 241, the rotating shaft 225 and the scraper 226 will no longer turn over, the reciprocating screw 23 will drive the sleeve 221, the sliding frame 222, the rotating shaft 225 and the scraper 226 to move toward the right end of the leveling frame 21, and the scraper 226 will push this part of the material to the right end of the leveling frame 21, so as to fill the concave part of the material layer in front.

[0025] If the rotating shaft 225 moves to the right end of the leveling frame 21, the second half gear 228 can mesh with the second rack 242 and rotate 180 degrees on the second gear. At this time, the rotating shaft 225 has driven the scraper 226 to flip 180 degrees around the axis of the rotating shaft 225. The upper end of the scraper 226 will first flip away from the center of the leveling frame 21 and then flip closer to the center of the leveling frame 21, so that the material pushed to the right end of the leveling frame 21 by the lower end of the scraper 226 is between the scraper 226 and the center of the leveling frame 21, avoiding Prevent this part of the material from escaping from the inner side of the leveling frame 21 so that this part of the material can fill the depression in the material layer in front; then the second half gear 228 will be detached from the second rack 242, the rotating shaft 225 and the scraper 226 will no longer flip, the reciprocating screw 23 will drive the sleeve 221, the sliding frame 222, the rotating shaft 225 and the scraper 226 to move toward the left end of the leveling frame 21, and the scraper 226 will push this part of the material to the left end of the leveling frame 21 to fill the depression in the material layer in front.

[0026] Guide plates 213 for the scraper 226 to turn over and abut against are installed on the inner walls on both sides of the leveling frame 21. During the turning process of the scraper 226, the upper end of the scraper 226 will turn over and abut against the guide plate 213, and the upper end of the scraper 226 will be at the lowest point of the guide plate 213 after turning 180 degrees, ensuring that the scraper 226 can push the materials pushed to the left and right ends of the leveling frame 21 back to the center of the leveling frame 21 as much as possible, so as to fill the concave part of the material layer in front.

[0027] It is worth noting that the guide plate 213 is arranged in an arc shape, and the material pushed onto the guide plate 213 by the scraper 226 will have a tendency to slide downward, so that the material tends to move to the lowest point of the guide plate 213, so that the scraper 226 can push this part of the material to the center of the leveling frame 21 after flipping.

[0028] like Figure 7 and Figure 8As shown, the compacting unit 3 includes two vertically arranged elastic telescopic rods 31 and a horizontally arranged transverse axis 33. The upper ends of the two elastic telescopic rods 31 are installed on the cart 1, and the lower ends of the two elastic telescopic rods 31 are connected to the same group of compacting plate groups 32. When the elastic telescopic rods 31 are in a natural state, the compacting plate group 32 will be higher than the lowest point of the rolling roller 4; the transverse axis 33 is connected to the cart 1 around its own axis and is fixedly sleeved with two cams 34, and the transverse axis 33 is connected to the rolling roller 4 through a belt drive. When the rolling roller 4 rolls forward, During the process, the horizontal shaft 33 will be driven to rotate by the belt drive, and the horizontal shaft 33 will drive the two cams 34 to rotate. The cams 34 will intermittently press down the compacting plate group 32 during the rotation, and the elastic telescopic rod 31 will be deformed in the process of the compacting plate group 32 being pressed down; when the compacting plate group 32 is pressed down to the lowest state, its lower surface is on the same horizontal plane as the lowest point of the rolling roller 4, that is, through the cooperation of the elastic telescopic rod 31 and the cam 34, the compacting plate group 32 can cyclically press down the leveled material layer, thereby realizing the compaction of the material layer.

[0029] The compacting plate group 32 includes a pressing plate 321, the upper surface of which is connected to a lifting plate 323 via two limiting plates 322, and the upper surface of the lifting plate 323 is connected to the lower end of the elastic telescopic rod 31. The cam 34 intermittently presses down the lifting plate 323 during the rotation process, and the lifting plate 323 causes the pressing plate 321 to rise and fall through the limiting plates 322, so as to realize the cyclic compaction of the material layer. like Figures 7 to 9 As shown, a vacuum cleaner 5 is installed on the cart 1, and a first dust hood 51, a second dust hood 52 and a third dust hood 53 are connected to the vacuum cleaner 5. The first dust hood 51 and the second dust hood 52 are respectively located at the front and rear sides of the compaction plate group 32, so that the dust generated during the compaction process can be vacuumed; the third dust hood 53 is located on the side of the rolling roller 4, so that the dust generated during the rolling process can be vacuumed.

[0030] The first dust hood 51 and the second dust hood 52 are both rotatably connected to the cart 1 and can be flipped on the vertical plane. The forward direction of the cart 1 is parallel to the flipping plane of the first dust hood 51 and the second dust hood 52. The first dust hood 51 and the second dust hood 52 are both connected to the cart 1 through a torsion spring 54, and a plurality of dust suction holes 511 are provided on opposite sides of the first dust hood 51 and the second dust hood 52.

[0031] When the convex end of the cam 34 abuts against the lifting plate 323, the pressing plate 321 will not rise to the highest state. At this time, the two limit plates 322 will respectively abut against the first dust hood 51 and the second dust hood 52, the torsion spring 54 will be in a deformed state, and the openings of the first dust hood 51 and the second dust hood 52 will be set downward so that the first dust hood 51 and the second dust hood 52 can absorb the dust generated during the compaction process; and the dust suction hole 511 will be closed by the limit plate 322, thereby ensuring the suction force at the openings of the first dust hood 51 and the second dust hood 52.

[0032] When the convex end of the cam 34 no longer contacts the lifting plate 323, the elastic telescopic rod 31 will cause the pressing plate 321 to rise to the highest state, the limit plate 322 will be separated from the first dust cover 51 and the second dust cover 52, the torsion spring 54 will return to its natural state and make the first dust cover 51 and the second dust cover 52 flip to a horizontal state, the openings of the first dust cover 51 and the second dust cover 52 will be connected, the first dust cover 51 and the second dust cover 52 will be located below the pressing plate 321 and be arranged with a gap with the lower surface of the pressing plate 321, and the dust suction hole 511 will face the lower surface of the pressing plate 321, and the material attached to the lower surface of the pressing plate 321 will enter the first dust cover 51 and the second dust cover 52 through the dust suction hole 511, so as to clean the material attached to the lower surface of the pressing plate 321, thereby ensuring the compaction effect of the pressing plate 321 on the material.

[0033] like Figure 7 and Fig.10 As shown, the third dust hood 53 is located between the pressing plate 321 and the rolling roller 4, and a cleaning plate 55 is installed on the third dust hood 53 to abut against the side wall of the rolling roller 4. The opening of the third dust hood 53 and the cleaning plate 55 are sequentially arranged along the rolling direction of the rolling roller 4. When the rolling roller 4 rolls forward, the cleaning plate 55 will scrape off the material attached to the side wall of the rolling roller 4, and the scraped material will be sucked away by the third dust hood 53, thereby ensuring the rolling effect of the rolling roller 4 on the material.

[0034] The implementation principle of the water conservancy construction rolling device of the embodiment of the present application is as follows: during the water conservancy construction process, after the construction workers spread the materials in the construction area, the construction workers will push the cart 1 forward in the construction area, the rolling roller 4 will roll forward and drive the reciprocating screw 23 and the horizontal shaft 33 to rotate through the belt transmission, the reciprocating screw 23 will drive the sleeve 221 to circulate during the rotation process, the sleeve 221 will drive the rotating shaft 225 and the scraper 226 to circulate through the sliding frame 222 and the processing cylinder, the scraper 226 will scrape the material back and forth, so that the material at the protruding part of the material layer can fill the concave part of the material layer, thereby leveling the material; and the scraper 226 will flip 180 degrees when moving to the left and right ends of the leveling frame 21, so that the material pushed to the left and right ends of the leveling frame 21 is pushed back to the center of the leveling frame 21 to achieve the filling of the concave part of the material layer in front; in addition, the material higher than the leveled material layer will be pushed forward by the rear end of the leveling frame 21 to fill the concave part of the material layer in front.

[0035] In addition, the horizontal shaft 33 will drive the cam 34 to rotate during the rotation process, and the cam 34 will intermittently press down the lifting plate 323 during the rotation process. The lifting plate 323 will drive the pressing plate 321 to press down the flattened material layer through the limit plate 322, thereby compacting the material layer; and when the pressing plate 321 presses down the material layer, the openings of the first dust hood 51 and the second dust hood 52 will be set downward, so that the first dust hood 51 and the second dust hood 52 can collect dust generated during the compaction process; When the convex end of the cam 34 no longer contacts the lifting plate 323, the elastic telescopic rod 31 will cause the pressing plate 321 to rise to the highest state, the torsion spring 54 will return to its natural state and cause the first dust hood 51 and the second dust hood 52 to flip to a horizontal state, and the material attached to the lower surface of the pressing plate 321 will enter the first dust hood 51 and the second dust hood 52 through the dust suction hole 511, so as to clean the material attached to the lower surface of the pressing plate 321, thereby ensuring the compaction effect of the pressing plate 321 on the material.

[0036] At the same time, the rolling roller 4 will roll the leveled and compacted material layer during the forward rolling process, and the cleaning plate 55 will scrape off the material attached to the side wall of the rolling roller 4. The scraped material will be sucked away by the third dust hood 53, ensuring the rolling effect of the rolling roller 4 on the material.

[0037] To sum up, construction workers can achieve simultaneous leveling, compacting and rolling by pushing the cart 1 forward, and construction workers do not need to walk back and forth between the construction starting point and the construction end point, thereby improving the construction efficiency of water conservancy construction; in addition, the present application uses the mutual cooperation of the scraper 226 and the leveling frame 21 to enable materials higher than the leveled material layer to be pushed forward to fill the depressions in the material layer in front. The present application uses the mutual cooperation of the first dust hood 51, the second dust hood 52 and the third dust hood 53 to achieve material cleaning on the lower surface of the pressure plate 321 and the side wall of the rolling roller 4, thereby improving the construction quality of water conservancy construction.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
