[0025] Reference Figures 1-8 A laterally movable and telescopic snow removal device, comprising: a walking vehicle body 2, wherein a front snow sweeping roller brush 1, a snow scraper or an icebreaker are attached to the front end of the walking vehicle body, and a telescopic snow sweeper 3 is attached to the rear end of the walking vehicle body.

[0026] The telescopic snow sweeper includes a fixed bracket 3.10 and a lifting roller brush slidably connected to the fixed bracket. The lifting roller brush includes a roller brush lifting gantry 3.9, at least one telescopic beam is connected to the roller brush lifting gantry, a roller brush bracket 3.3 is fixed to the end of the telescopic beam, and a roller brush 3.1 is connected to the roller brush bracket.

[0027] Reference Figure 9 When the telescopic beam is a single section, it extends into a square beam approximately 7 meters long. A roller brush bracket is fixed to the rear end of the square beam, and the roller brush bracket and the roller brush are rotatably connected. In this way, when the snowplow is sweeping snow, the front roller brush sweeps the lane while the rear roller brush can clean the adjacent second lane, increasing the working area and improving work efficiency. At this time, the telescopic beam extends into a fixed beam that is the entire length.

[0028] The left and right sides of the roller brush lifting gantry are connected to roller brush lifting rollers 3.8. The fixed bracket is fixed with roller brush lifting guide column 3.7. The roller brush lifting roller is located inside the roller brush lifting guide column. The roller brush lifting roller can be a guide sleeve. The guide sleeve is located inside the roller brush lifting guide column. The fixed bracket is fixed to one end of the lifting device. The lifting end of the lifting device is fixed to the roller brush lifting gantry. The lifting device is a roller brush lifting cylinder 3.12.

[0029] The roller brush bracket is connected to the top of the roller brush via a rotating shaft. The roller brush bracket is hinged to the cylinder end of the roller brush angle adjusting cylinder 3.2. The push rod end of the roller brush angle adjusting cylinder is hinged to one side of the roller brush 3.1.

[0030] When the telescopic beam has at least two sections, as shown in the figure, there are four telescopic beams in total. These four sections are extended and retracted by three telescopic hydraulic cylinders, including the first telescopic beam 3.11, the second telescopic beam 3.6, the third telescopic beam 3.5, and the fourth telescopic beam 3.4. The first telescopic beam is fixed to the roller brush lifting gantry, and its extension is inward. Therefore, both sides of the first, second, and third telescopic beams have notches to facilitate the extension and retraction of the inner telescopic beams. The cylinder body end of the first telescopic hydraulic cylinder 3.13 is fixed to the roller brush lifting gantry. The extension rod end of the first telescopic hydraulic cylinder is fixed to the first telescopic hydraulic cylinder hinge seat 3.20 fixed on the second telescopic beam. The cylinder body end of the second telescopic hydraulic cylinder is fixed to the second telescopic hydraulic cylinder fixing ear plate 3.17 fixed on the second telescopic beam. The extension rod end of the second telescopic cylinder is fixed to the second telescopic cylinder hinge seat 3.19 fixed on the third telescopic beam. The cylinder body end of the third telescopic cylinder is fixed to the third telescopic cylinder fixing ear plate 3.16 fixed on the third telescopic beam. The extension rod end of the third telescopic cylinder is fixed to the third telescopic cylinder hinge seat 3.18 fixed on the fourth telescopic beam. In this way, when the snow sweeping operation is performed, the roller brush lifting cylinder is activated to lower the roller brush. The first, second, and third telescopic cylinders are activated. The first telescopic cylinder extends to push out the second telescopic beam, the second telescopic cylinder pushes out the third telescopic beam, and the third telescopic cylinder pushes out the fourth telescopic beam. After being pushed out, the roller brush extends to the outside of the machine to achieve the purpose of sweeping the second road. After the operation is completed, it is retracted in one go.

[0031] When the four telescopic beams extend and retract via a telescopic hydraulic cylinder, refer to... Figures 10-12The system includes a first telescopic beam, a second telescopic beam, a third telescopic beam, and a fourth telescopic beam. The first telescopic beam is fixed to the roller brush lifting gantry and its telescopic mechanism is inward telescopic. Therefore, both sides of the first, second, and third telescopic beams have notches to facilitate the extension and retraction of the internal telescopic beams. The cylinder end of the first telescopic cylinder is fixed to the first telescopic beam, and the extension rod end is connected to the hinge seat of the first telescopic cylinder fixed on the second telescopic beam. The extension end of the second telescopic beam is connected to a first pulley 3.21, the extension end of the third telescopic beam is connected to a second pulley 3.22, the end of the third telescopic beam located inside the second telescopic beam is connected to a third pulley 3.23, and the end of the fourth telescopic beam located inside the third telescopic beam is connected to a fourth pulley 3.24. A first connecting rope 3.25 is wound around the first pulley. One end of the first connecting rope is fixed to a fixing block 3.29 of the first telescopic beam. After passing around the first pulley, the first connecting rope passes through the end of the second telescopic beam. The first pulley has a notch fixed to the third telescopic beam. A second connecting rope 3.26 is wound around the second pulley. One end of the second connecting rope is fixed to the fixing block of the second telescopic beam. After passing around the second pulley, it passes through the notch of the third telescopic beam and is fixed to the fourth telescopic beam. A third connecting rope 3.27 is wound around the third pulley. One end of the third connecting rope is fixed to the fixing block inside the first telescopic beam. After passing around the third pulley, it is fixed to the fixing block inside the second telescopic beam. A fourth connecting rope 3.28 is wound around the fourth pulley. One end of the fourth connecting rope is fixed to the fixing block inside the second telescopic beam. The other end passes around the fourth pulley and is fixed to the fixing block inside the third telescopic beam. The connecting rope can be a wire rope or a chain. In the figure, the first and second pulleys are located outside the telescopic beam, and the third and fourth pulleys are located inside the telescopic beam. The third and fourth pulleys can also be set outside the telescopic beam, as long as the telescopic beam has a notch for the connecting rope to pass through.

[0032] The traveling vehicle is a flatbed truck, loader, or grader. This device is simply attached to the traveling vehicle without requiring any modifications. A snow sweeping roller / icebreaker is attached to the front end. Both the snow sweeping roller and the icebreaker are existing technologies. This application simply attaches them to the vehicle to enable one vehicle to clear snow from two lanes simultaneously. The specific structural form and working principle are not described in detail here. This device is simply applied in this context.
