[0037] Example 2

[0038] like Figure 2 , Figure 3 , Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a card slot 11 is symmetrically opened on one side of the bottom plate 1, the inner cavity of the card slot 11 is slidably connected to the bottom plate 2 13, and the side of the bottom plate 2 13 close to the card slot 11 is threadedly connected with a bolt 12, and the bolt 12 is threadedly connected to the bottom plate 1;

[0039] The limiting structure 3 includes a connecting disk 31, and a turntable 32 is rotatably connected to the side of the connecting disk 31 away from the stone roller 4. The inner cavity of the turntable 32 on the same side is threadedly connected to the outer surface of the rotating shaft 2 on the same side. A circular array is fixedly connected to a plurality of clamping columns 33 on the side of the connecting disk 31 close to the stone roller 4. A plurality of clamping grooves 41 are opened in the circular array in the middle of the stone roller 4, and the plurality of clamping grooves 41 are used in conjunction with a plurality of clamping columns 33.

[0040] In this embodiment, as can be seen from the above, when the device needs to be adjusted according to the width of the road surface, the bolt 12 is first rotated to separate the bolt 12 from the bottom plate 1, thereby releasing the position limit of the bottom plate 2 13, and then the bottom plate 2 13 is slid and removed from the inner cavity of the slot 11, and then the turntable 32 is rotated to rotate with the shaft 2, and then the turntable 32 is used to drive the connecting plate 31 and the plurality of clamping columns 33 to move, so that the limiting structure 3 is removed from the outside of the shaft 2.

[0041] Example 3

[0042] like Figure 6 and Figure 7 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the water tank 51 includes a box body 511, the lower end of the box body 511 is fixedly connected to the upper end of the bottom plate 1, the upper end of the box body 511 is provided with a water inlet groove 513 that penetrates the end surface of the box body 511 and extends to the inner cavity of the box body 511, and an observation window 512 is provided on one side of the box body 511.

[0043] In this embodiment, as can be seen from the above, when water needs to be poured into the device, the staff pours the water into the inner cavity of the funnel 71, and then the water resources will flow into the inner cavity of the fixed block 72 through the inner cavity of the funnel 71. When the water resources pass through the inner cavity of the fixed block 72, the filter plate 74 can be used to filter the water resources, and some impurities with larger particles are intercepted on the filter screen on the bottom wall of the inner cavity of the filter plate 74, thereby preventing these impurities from entering the inner cavity of the water tank 51, thereby causing damage to the water pump 52 and affecting the service life of the water pump 52. When the impurities in the inner cavity of the filter plate 74 are collected to a certain amount, the filter plate 74 can be slid and removed from the inner cavity of the slide 73, and then the impurities collected by the filter plate 74 can be processed.

[0044] Example 4

[0045] like Figure 5As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the sprinkler structure 5 includes a water tank 51, a water pump 52 is fixedly connected to the bottom wall of the inner cavity of the water tank 51, a water pipe 53 is fixedly connected to the output end of the water pump 52, the input end of the water pipe 53 passes through the inner cavity of the water tank 51 and extends to the outer surface of the water tank 51, and the output end of the water pipe 53 passes through the outer surface of the water tank 51 and extends to the inner cavity of the water tank 51, a plurality of nozzles 54 are fixedly connected to one side of the water pipe 53, and the inner cavities of the plurality of nozzles 54 are communicated with the inner cavity of the water pipe 53.

[0046] In this embodiment, as can be seen from the above, when it is necessary to sprinkle water on the road surface, while water is transported into the inner cavity of the box 511 through the water inlet trough 513, the staff can observe the water level in the inner cavity of the box 511 through the observation window 512. When the water level in the inner cavity of the box 511 reaches a certain position, pouring water into the inner cavity of the funnel 71 can be stopped. During the operation of the device, the water pump 52 can be used to transport the water in the inner cavity of the box 511 to the inner cavity of the water pipe 53, and then through the cooperation of the water pipe 53 and a plurality of nozzles 54, the water resources can be sprayed onto the road surface, so that the road surface can maintain a certain humidity, which is convenient for the stone roller 4 to roll and level the road surface.

[0047] The following is a detailed description of the working principle of the road leveling equipment used in road construction.

[0048] like Figure 1-7 As shown, when the device needs to be adjusted according to the width of the road surface, first rotate the bolt 12 to separate the bolt 12 from the bottom plate 1, thereby releasing the position limit of the bottom plate 2 13, and then slide the bottom plate 2 13 out of the inner cavity of the card slot 11, and then rotate the turntable 32 to rotate the turntable 32 and the shaft 2, and then use the turntable 32 to drive the connecting plate 31 and the plurality of clamping columns 33 to move, so that the limiting structure 3 is removed from the outer surface of the shaft 2, and the position limit of the stone roller 4 is released, and then according to the width of the road surface, the number of stone rollers 4 on the outer surface of the shaft 2 is adjusted. After the stone rollers 4 on the outer surface of the shaft 2 are adjusted to a suitable number, the turntable 32 is then rotated through the outer surface of the shaft 2, and the turntable 32 is used to drive the connecting plate 31 and the plurality of clamping columns 33 to reset, so that the outer surface of the clamping column 33 is slid and pushed into the inner cavity of the card slot 2 41 with the same center, and the position of the plurality of stone rollers 4 is limited by the limiting structure 3;

[0049] Then the staff pours water into the inner cavity of the funnel 71, and then the water resources will flow into the inner cavity of the fixed block 72 through the inner cavity of the funnel 71. When the water resources pass through the inner cavity of the fixed block 72, the filter plate 74 can be used to filter the water resources, and some impurities with larger particles are intercepted on the filter screen on the bottom wall of the inner cavity of the filter plate 74, thereby preventing these impurities from entering the inner cavity of the water tank 51, thereby causing damage to the water pump 52 and affecting the service life of the water pump 52. When the impurities in the inner cavity of the filter plate 74 are collected to a certain amount, the filter plate 74 can be slid and removed from the inner cavity of the chute 73, and then the impurities collected by the filter plate 74 can be processed;

[0050] While water is being transported into the inner cavity of the box 511 through the water inlet trough 513, the staff can observe the water level in the inner cavity of the box 511 through the observation window 512. When the water level in the inner cavity of the box 511 reaches a certain position, pouring water into the inner cavity of the funnel 71 can be stopped. During the operation of the device, the water in the inner cavity of the box 511 can be transported to the inner cavity of the water pipe 53 by using the water pump 52, and then the water resources can be sprayed onto the road surface through the cooperation of the water pipe 53 and a plurality of nozzles 54, so that the road surface can maintain a certain humidity, thereby facilitating the rolling and leveling of the road surface by the stone roller 4.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
