Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] like Figure 1-5As shown, the utility model provides a road roller with adjustable weight, including a road roller body 1, the road roller body 1 includes a control room 2, a connecting cross plate 3 is arranged on the bottom rear end of the control room 2, a moving wheel 4 is arranged on the bottom front end of the control room 2, a rolling unit is arranged on the inner side of the connecting cross plate 3, and weight adjustment units are arranged on the outer surfaces of both sides of the connecting cross plate 3. The weight adjustment unit includes a connecting block 33 arranged on the outer surfaces of both sides of the connecting cross plate 3, and a counterweight block 34 is detachably installed on the outer surface of the connecting block 33. A through groove 341 is opened inside the counterweight block 34, and positioning holes 342 are opened on the upper and lower ends of the through groove 341. A cavity 331 is opened inside the connecting block 33, and the right inner side of the cavity 331 is provided with a positioning hole 342. A sliding groove 332 is provided on the wall, and a fixed vertical rod 333 is fixedly installed on the upper and lower ends of the inner part of the sliding groove 332, and a positioning block 334 is slidably sleeved on the outer surfaces of the upper and lower ends of the fixed vertical rod 333, and a return spring 335 is movably sleeved on the outer surface of the fixed vertical rod 333 located above and below the positioning block 334, and a resistance block 336 is movably installed on the left side of the positioning block 334, and a resistance rod 337 is fixedly installed on the left outer surface of the resistance block 336, a threaded pipe mouth 338 is fixedly installed on the outer surface of the front end of the connecting block 33, and a fixed sleeve 339 is rotatably sleeved on the left end of the resistance rod 337, an internal thread 3310 is provided on the inner wall of the fixed sleeve 339, and the fixed sleeve 339 is threadedly sleeved on the outer surface of the threaded pipe mouth 338.

[0026] Furthermore, when rolling different road surfaces, the rolling force can be adjusted as needed by engaging the counterweight block 34 of the required weight on the outer surface of the connecting block 33. At this time, the contact rod 337 is pushed inward so that the contact block 336 at the other end of the contact rod 337 is squeezed between the upper and lower groups of positioning blocks 334. The inclined surfaces on both sides fit together, so that the upper and lower groups of positioning blocks 334 continuously move in opposite directions and slide on the outer surface of the fixed vertical rod 333. The two groups of positioning blocks 334 move in opposite directions and can extend out of the upper and lower end outer surfaces of the connecting block 33, and then be inserted into the positioning hole 342 inside the counterweight block 34, so that the installation of the counterweight block 34 is fixed. At this time, the fixing sleeve 339 is rotated, and the internal thread 3310 inside the fixing sleeve 339 is sleeved on the outer surface of the threaded pipe mouth 338, so that the existing position of the internal components is fixed. Example

[0027] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the rolling unit includes a rotating groove 31 arranged on the inner walls on both sides of the connecting cross plate 3, and a rolling roller 32 is rotatably installed inside the rotating groove 31. A buffer groove 35 is opened on the inner side of the rear end of the connecting cross plate 3, and telescopic rods 36 are fixedly installed on both sides of the buffer groove 35. A scraper plate 37 is fixedly installed on the other end of the telescopic rod 36, and the other end of the scraper plate 37 is fitly connected to the outer surface of the rolling roller 32.

[0028] Furthermore, the control room 2 controls the moving wheel 4 to facilitate moving the device to a desired position. When moving to a certain place, the rolling roller 32 is caused to rotate inside the rotating groove 31, thereby rolling and leveling the ground. When the rolling roller 32 rotates, the scraper blade 37 is used to scrape off the mud attached to its outer surface to prevent the adhesion from causing uneven road surface rolling.

[0029] The working principle of the adjustable weight roller is described in detail below.

[0030] like Figure 1-5 As shown, when in use, the control room 2 controls the moving wheel 4 to facilitate moving the device to a desired position. When moving to a certain place, the rolling roller 32 is prompted to rotate inside the rotating groove 31, thereby rolling and leveling the ground. When the rolling roller 32 rotates, the scraper blade 37 is used to scrape off the mud attached to its outer surface to prevent the mud from being unevenly rolled due to adhesion. At the same time, when rolling different road surfaces, the rolling force can be adjusted as needed. By engaging the counterweight block 34 of the required weight on the outer surface of the connecting block 33, the contact rod 337 is pushed inward at this time, so that the other end of the contact rod 337 is The resistance block 336 is squeezed between the upper and lower groups of positioning blocks 334, and the inclined surfaces on both sides fit together, so that the upper and lower groups of positioning blocks 334 continuously move in opposite directions and slide on the outer surface of the fixed vertical rod 333. The two groups of positioning blocks 334 move in opposite directions and can extend out of the upper and lower end outer surfaces of the connecting block 33, and then be inserted into the positioning hole 342 inside the counterweight block 34, so that the installation of the counterweight block 34 is fixed. At this time, the fixing sleeve 339 is rotated, and the internal thread 3310 inside the fixing sleeve 339 is sleeved on the outer surface of the threaded pipe mouth 338, so that the existing position of the internal components is fixed.

[0031] 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 deviate from the spirit of the present invention are within the scope of protection of the present invention.
