Technical Field

[0001] This invention relates to the field of snowplow technology, and more particularly to a snowplow. Background Technology

[0002] Existing snowplows are mostly used for pushing and shoveling snow. In particular, large snowplows have difficulty clearing the snow around the curb during the snow removal process. It is necessary to manually shovel the snow at the base of the curb to the middle of the road, which results in low work efficiency and high labor intensity for workers. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a snowplow. The snowplow provided by this invention has a simple structure and can effectively clear snow accumulated at the base of curbs with high efficiency.

[0004] The technical means employed in this invention are as follows:

[0005] A snowplow includes: a sweeper, wherein a left brush turntable and a right brush turntable are arranged on both sides of the front end of the chassis of the sweeper, and a snow guiding device is arranged between the two brush turntables and the chassis. The snow guiding device includes a lifting frame, a left snowplow and a right snowplow on both sides of the front end of the lifting frame, and a guide block arranged between the left snowplow and the right snowplow. The lifting frame is vertically mounted below the chassis, the two snowplows are located corresponding to the rear sides of the two brush turntables, and the guide block is horizontally swaying. At the front center of the lifting frame, the guide block includes a left guide surface and a right guide surface arranged adjacent to each other. The ends of the left and right guide surfaces that are far apart from each other are provided with rear side surfaces. The rear end of the guide block is hinged to the lifting frame. When the guide block swings to the right, the left guide surface aligns with the left snowplow, and the right edge of the left guide surface contacts the brush on the right brush turntable. When the guide block swings to the left, the right guide surface aligns with the right snowplow, and the left edge of the right guide surface contacts the brush on the left brush turntable.

[0006] Furthermore, the lifting frame is mounted on the chassis via a lifting cylinder.

[0007] Furthermore, the brush turntable is driven by a hydraulic motor.

[0008] Furthermore, both the left and right snowplows are tilted towards the rear of the chassis.

One end of the connecting plate is fixed to the lifting frame, and the other end of the connecting plate extends into the cavity and is hinged to one end of the compression spring. The other end of the compression spring is hinged to the top wall of the cavity.

[0011] Furthermore, the rear side of the guide block is provided with adjacent left and right limiting surfaces. When the left guide surface aligns with the left snowplow, the left limiting surface abuts against the lifting frame. When the right guide surface aligns with the right snowplow, the right limiting surface abuts against the lifting frame.

[0012] Furthermore, adjusting bolts are respectively provided on the vertical support plate at the front end of the lifting frame at the positions corresponding to the left and right limiting surfaces on the guide block. The adjusting bolts are threadedly connected to the vertical support plate and are used to adjust the contact angle between the left and right guide surfaces of the guide block and their corresponding brushes.

[0013] Furthermore, it also includes a blower pipe, which is mounted on the chassis and located between the left brush turntable and the right brush turntable. The air inlet of the blower pipe is connected to the exhaust port of the vacuum cleaner of the sweeper, and the air outlet of the blower pipe can be selectively directed towards the left guide surface or the right guide surface.

[0014] Furthermore, it also includes a side guide plate, which is obliquely disposed on the right front side of the right snowplow, with the lower end of the side guide plate close to the road surface and approaching the right brush turntable side, and the upper end of the side guide plate extending out of the curb.

[0015] Furthermore, both the lifting cylinder and the hydraulic motor are connected to the sweeper's hydraulic system.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-8 As shown, a snowplow includes: a snowplow 1, with a left brush turntable 2 and a right brush turntable 3 arranged on both sides of the front end of the chassis of the snowplow 1. A snow guiding device is arranged between the two brush turntables and the chassis. The snow guiding device includes a lifting frame 4, a left snowplow 5 and a right snowplow 6 arranged on both sides of the front end of the lifting frame 4, and a guide block 7 arranged between the left snowplow 5 and the right snowplow 6. In this embodiment, the lifting frame includes a horizontal support plate 4.1 parallel to the chassis and a vertical support plate 4.2 fixedly arranged on the front end of the horizontal support plate 4.1. The left snowplow 5 and the right snowplow 6 are welded and fixed to both sides of the vertical support plate 4.2. It should be noted that the snowplow and the brush turntable in this embodiment are prior art.

[0030] In this embodiment, the lifting frame 4 is mounted vertically and flexibly under the sweeper chassis via four evenly distributed lifting cylinders 17. Specifically, one end of the lifting cylinder 17 is connected to the chassis, and the other end is connected to the horizontal support plate of the lifting frame 4. The lifting cylinders 17 extend and retract to drive the lifting frame 4 to descend and rise vertically. Its structure is relatively reasonable and easy to operate.

[0031] like Figure 1-6As shown, in this embodiment, the two snowplows are located on the rear side of the two brush turntables. The guide block 7 is installed in the middle of the front end of the lifting frame 4, which can swing left and right. Specifically, the guide block 7 includes a left guide surface 7.1 and a right guide surface 7.2 arranged adjacent to each other. The ends of the left guide surface 7.1 and the right guide surface 7.2 that are far apart from each other are provided with a rear side. The rear end of the guide block 7 is hinged to the lifting frame 4, thereby realizing the left and right swing of the guide block 7.

[0032] Specifically, the guide block 7 is hinged to the lifting frame 4 via the hinge pin 8 and the ear plate 9. The ear plate 9 is fixed on the lifting frame 4, and the hinge pin 8 is vertically inserted between the guide block 7 and the ear plate 9.

[0033] When in use, to clear snow near the curb on the right side of the snowplow, the guide block 7 swings to the right, and the left guide surface 7.1 aligns with the left snowplow 5, facilitating snow removal towards the center of the road. The right edge of the left guide surface 7.1 contacts the brush on the right brush disc 3, and the right guide surface 7.2 abuts against the right snowplow 6, facilitating snow pushing. At this time, the right brush disc 3 (i.e., the brush disc near the curb on the right side of the snowplow) rotates counterclockwise, and the left brush disc 2 rotates clockwise.

[0034] When clearing snow from the curb near the left side of the snowplow, guide block 7 swings to the left, and right guide surface 7.2 aligns with right snowplow 6 to facilitate snow removal towards the center of the road. The left edge of right guide surface 7.2 contacts brush 15 on left brush turntable 2, and right guide surface 7.2 abuts against right snowplow 6 to facilitate snow pushing. Left brush turntable 2 (i.e., the brush turntable near the curb near the left side of the snowplow) rotates clockwise, and right brush turntable 3 rotates counterclockwise.

[0035] To facilitate snow removal to the middle of the road, both the left snowplow 5 and the right snowplow 6 are tilted towards the rear of the chassis.

[0036] It should be noted that the snowplow in this embodiment can effectively clear snow near the base of the curb through the cooperation of the guide block 7 and the snowplow blade. It has a simple structure and high efficiency.

[0037] like Figure 6 As shown, to facilitate the positioning of the guide block 7, a cavity is formed on the bottom surface of the guide block 7. A spring limiting assembly is installed inside the cavity. The spring limiting assembly includes a compression spring 10 and a connecting plate 11. One end of the connecting plate 11 is fixed to the vertical support plate 4.2 at the front end of the lifting frame 4, and the other end of the connecting plate 11 extends into the cavity and is hinged to one end of the compression spring 10. The other end of the compression spring 10 is hinged to the top wall of the cavity. A strip-shaped hole matching the connecting plate is formed on the rear side of the guide block. In use, when the guide block 7 swings to the left or right, the compression spring 10 is in a contracted and reset state. It should be noted that the spring limiting assembly in this embodiment has a simple and reasonable structure, facilitating the positioning of the guide block after swinging.

[0038] To improve the precise positioning of the guide block 7, adjacent left limiting surfaces 7.3 and right limiting surfaces 7.4 are provided on the rear side of the guide block 7. When the left guide surface 7.1 aligns with the left snowplow 5, the left limiting surface 7.3 abuts against the lifting frame, and the compression spring 10 retracts and resets; when the right guide surface 7.2 aligns with the right snowplow 6, the right limiting surface 7.4 abuts against the lifting frame, and the compression spring 10 retracts and resets.

[0039] In this embodiment, during use, the brush bristles of the rotary brush may wear down and shorten. This can lead to excessive spacing between the left and right guide surfaces on the guide block and the brush, preventing the brush from contacting the guide surfaces. Consequently, the snow swept by the brush cannot be discharged through the guide surfaces to the corresponding snowplow, resulting in incomplete cleaning. To solve the above problem, such as... Figure 8 As shown, in this embodiment, adjusting bolts 18 are respectively provided on the vertical support plate 4.2 at the front end of the lifting frame, corresponding to the left limiting surface 7.3 and the right limiting surface 7.4 on the guide block. The vertical support plate 4.2 has threaded holes adapted to the adjusting bolts 18. The adjusting bolts 18 are threadedly connected to the threaded holes on the vertical support plate 4.2. The adjusting bolts 18 are used to adjust the contact angle between the left and right guide surfaces of the guide block and their corresponding brushes. In use, the adjusting bolts 18 are screwed on so that the front end of the adjusting bolts 18 extends out of the vertical support plate 4.2 and abuts against its corresponding limiting surface (left limiting surface 7.3 or right limiting surface 7.4), thereby adjusting the interval between the corresponding guide surface (left guide surface 7.1 or right guide surface 7.2) and the brush, ensuring that the brush contacts the guide surface on the guide block, and ultimately ensuring smooth snow removal.

[0040] During the use of this embodiment, the applicant found that during snow removal, the snow in the middle of the guide road easily piled up, forming a snow slab significantly higher than the road surface, affecting subsequent salting and snow removal, and also affecting vehicle traffic. To avoid the formation of snow slabs, such as... Figure 3 , Figure 6 The embodiment also includes a blower pipe 12, which is mounted on the chassis and located between the left brush turntable 2 and the right brush turntable 3. The air inlet of the blower pipe 12 is connected to the exhaust port of the vacuum cleaner of the sweeper vehicle 1, and the exhaust port of the blower pipe 12 can selectively blow towards the left guide surface 7.1 or the right guide surface 7.2. Specifically, when clearing snow near the curb on the right side of the snowplow vehicle to the middle of the road, the exhaust port of the blower pipe 12 blows towards the left snowplow 5 side; when clearing snow near the curb on the left side of the snowplow vehicle to the middle of the road, the exhaust port of the blower pipe 12 blows towards the right snowplow 6 side. It should be noted that this embodiment, by setting up the blower pipe, can evenly spread snow to one side of the middle of the road, avoiding the formation of snow clumps, and also improving snow removal efficiency.

[0041] In addition, during the snow removal process, in order to utilize the snow near the base of the curb and drain it into the green belt outside the curb, such as... Figure 7 As shown, this embodiment also includes a side guide plate 13, which is obliquely disposed on the right front side of the right snowplow 6. The lower end of the side guide plate 13 is close to the road surface and approaches the right brush turntable 3, while the upper end of the side guide plate 13 extends beyond the curb and reaches the green belt outside the curb. At this time, the exhaust port of the blower pipe 12 blows towards the side guide plate 13. It should be noted that in this embodiment, the combination of the blower pipe 12 and the side guide plate 13 can discharge the snow accumulated at the base of the curb to the green belt outside the curb, utilizing the snow and promoting the growth of vegetation in the green belt. It should also be noted that this embodiment improves snow removal efficiency by using the combination of the blower pipe and the side guide plate.

[0042] It should be noted that the brush turntable in this embodiment includes a turntable 14, a brush 15, and a hydraulic motor 16. The turntable is driven by the hydraulic motor 16. Both the lifting cylinder 17 and the hydraulic motor 16 are connected to the hydraulic system of the sweeper 1.
