Description

Technical Field

[0001] The utility model relates to the technical field of snow removal equipment, and more specifically, to a snow scraper. Background Art

[0002] After winter snowfall, road recovery in oilfields is slow. Clearing snow from roads is time-consuming and costly, causing significant inconvenience to production and workers. Common methods for clearing snow from roads include manual shoveling, snowmelt, and mechanized clearing. Snowmelt, a chemical product, is not only expensive but also harms roadside vegetation, making it unsuitable for large-scale use. Manual clearing is inefficient and doesn't meet the requirements for rapid snow removal. Currently, commonly used mechanized clearing equipment is typically large, fully functional equipment with complex structures, high manufacturing costs, and high price. It also requires expensive repair and maintenance.

[0003] Utility model patent publication number CN211498696U discloses a snowplow comprising a first blade, a second blade, a first support member, and an external connector. The first blade and the second blade are disposed opposite each other, with a first end of the first blade connected to a first end of the second blade, and the second end of the first blade remote from the second end of the second blade. The first support member has two ends connected to the second end of the first blade and the second end of the second blade, respectively. The first blade, the second blade, and the first support member, taken in a direction parallel to the ground and passing through the first support member, form an isosceles triangle. The external connector is movably connected to an outer wall of the snowplow and is configured to connect to a power traction device in a direction in which the first ends of the first blade and the second blade face away from their respective second ends. The snowplow has a simple structure and can be connected to the rear side of the power traction device. As the snowplow moves with the power traction device, the sharp corners of the triangle push away accumulated snow and flip it to the sides, quickly clearing the road. However, its disadvantage is that the angle between the first shovel blade and the second shovel blade is fixed, so that the overall width of the snow shovel is also fixed, and it cannot be adjusted according to roads of different widths, which limits its use.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1:

[0028] like Figure 1 、 Figure 2 As shown, the snow scraper in this embodiment includes a first scraper 1 and a second scraper 2, which are connected at one end and separated from each other at the other end. External connectors 3 are provided on the sides of the first scraper 1 and the second scraper 2 that are separated from each other. External connectors 3 are used to connect to external traction equipment. The first scraper 1 and the second scraper 2 are rotationally connected by a rotary connection. An adjustment connection is provided between the sides of the first scraper 1 and the second scraper 2 that are close to each other. The adjustment connection is connected to the first scraper 1 and the second scraper 2 and is used to adjust the angle between the first scraper 1 and the second scraper 2.

[0029] In this embodiment, the adjustment connection device includes an adjustment sleeve 4 and a first adjustment rod 5. Adjustment nuts 6 are rotatably provided at both ends of the adjustment sleeve 4, and the adjustment nuts 6 are coaxially arranged with the adjustment sleeve 4. The first adjustment rod 5 is a screw. One end of the first adjustment rod 5 is inserted into the adjustment sleeve 4 and is threadedly connected to the adjustment nut 6. The other end of the first adjustment rod 5 is rotatably connected to the first scraper 1 or the second scraper 2. Specifically, a first connecting ear plate 19 is installed on the side of the first scraper 1 and the second scraper 2 that is close to each other. A second connecting ear plate 20 is fixed to the end of the first adjustment rod 5 away from the adjustment sleeve 4. The first connecting ear plate 19 and the second connecting ear plate 20 are rotatably connected via a hinge or a pin, so that the first adjustment rod 5 can rotate horizontally with the hinge or pin as the center.

[0030] The snow scraper in this embodiment can adjust the length of the first adjusting rod 5 exposed outside the adjusting sleeve 4 by rotating the adjusting nut 6. Since the adjusting nut 6 is threadedly connected to the first adjusting rod 5, the angle between the first scraper 1 and the second scraper 2 can be changed, and finally the width of the entire snow scraper can be adjusted to adapt to roads of different widths and clear snow on roads of different widths.

[0031] In this embodiment, the rotating connection device includes a second rotating shaft 12 and four rotating connection sleeves 18 movably mounted on the second rotating shaft 12. Baffles (not shown in the figure) are fixedly provided at both ends of the second rotating shaft 12 to prevent the second rotating shaft 12 from escaping from the rotating connection sleeves 18. The four rotating connection sleeves 18 are fixedly connected to the first scraper 1 or the second scraper 2, and the rotating connection sleeves 18 connected to the first scraper 1 and the second scraper 2 are arranged at intervals.

[0032] In this embodiment, the external connecting member 3 is arranged in the middle of the first scraper 1 and the second scraper 2 in the vertical direction. Specifically, the external connecting member 3 can be a hanging ring, a hanging ear, a connecting tube or other structures. A connecting rope 15 is provided on the two external connecting members 3. Specifically, the two ends of the connecting rope 15 are respectively tied to the two external connecting members 3. When in use, the connecting rope 15 is hung on the tail of the external traction device, thereby connecting the snow scraper to the external traction device.

[0033] In this embodiment, balancing correction ropes 14 are symmetrically provided on the top of the first scraper 1 and the second scraper 2, and the balancing correction ropes 14 are located on the outside of the external connecting member 3. When in use, the two balancing correction ropes 14 are symmetrically connected to the two sides of the tail of the external traction device, thereby preventing the snow scrapers from deflecting during the snow clearing process. A reinforcement frame is provided on the sides of the first scraper 1 and the second scraper 2 that are close to each other. The reinforcement frame includes a cross bar 16 located at the upper and lower ends of the first scraper 1 or the second scraper 2 and a plurality of vertical bars 17 arranged between the cross bars 16. The cross bar 16 is fixedly connected to the first scraper 1 or the second scraper 2. The first scraper 1, the second scraper 2 and the reinforcement frame are all made of steel, and the cross bar 16 and the vertical bars 17 are steel pipes. The cross bar 16 is welded to the first scraper 1 or the second scraper 2. A connecting ring is welded to the top of the upper cross bar 16, and the balancing correction rope 14 is tied to the connecting ring.

[0034] By arranging reinforcement frames on the sides of the first scraper 1 and the second scraper 2 that are close to each other, on the one hand, the arrangement of the reinforcement frames can reinforce the first scraper 1 and the second scraper 2, and on the other hand, the arrangement of the reinforcement frames can increase the weight of the first scraper 1 and the second scraper 2, thereby playing a weighting role and preventing the snow scraper from tipping over.

[0035] The working principle of the snow scraper in this embodiment is:

[0036] The first scraper 1 and the second scraper 2 are rotatably connected by a second rotating shaft 12 and four rotating connecting sleeves 18 movably mounted on the second rotating shaft 12, and an adjusting sleeve 4, a first adjusting rod 5 and an adjusting nut 6 are provided between the sides of the first scraper 1 and the second scraper 2 that are close to each other. By rotating the adjusting nut 6, the length of the first adjusting rod 5 exposed outside the adjusting sleeve 4 can be adjusted, thereby changing the angle between the first scraper 1 and the second scraper 2, and finally adjusting the width of the entire snow scraper to adapt to roads of different widths and clear snow on roads of different widths.

[0037] Example 2:

[0038] like Figure 3As shown, the adjustment connection device in this embodiment includes an adjustment sleeve 4 and a first adjustment rod 5. One end of the first adjustment rod 5 is slidably inserted into the adjustment sleeve 4. Locking threaded holes are radially formed at both ends of the adjustment sleeve 4, and locking bolts 7 are provided in the locking threaded holes. When the locking bolts 7 are tightened, the locking bolts 7 abut against the first adjustment rod 5, thereby limiting the telescopic sliding of the first adjustment rod 5 and fixing the length of the first adjustment rod 5 exposed outside the adjustment sleeve 4. When the locking bolts 7 are loosened, the locking bolts 7 are separated from the first adjustment rod 5, and the first adjustment rod 5 can slide axially along the adjustment sleeve 4, thereby adjusting the length of the first adjustment rod 5 exposed outside the adjustment sleeve 4, thereby changing the angle between the first scraper 1 and the second scraper 2, and ultimately adjusting the width of the entire snow scraper to adapt to roads of different widths and clear snow on roads of different widths.

[0039] Example 3:

[0040] like Figure 4 、 Figure 5 As shown, the adjustment connection device in this embodiment includes a second adjustment rod 8 and a support rod 9. The second adjustment rod 8 is arranged on the side where the first scraper 1 and the second scraper 2 are close to each other, and one end of the second adjustment rod 8 is rotatably arranged at the connection between the first scraper 1 and the second scraper 2. An adjustment sleeve 10 is provided on the second adjustment rod 8, and the adjustment sleeve 10 is rotatably and slidingly connected to the second adjustment rod 8. Two support rods 9 are arranged on both sides of the second adjustment rod 8, and one end of the support rod 9 is rotatably connected to the adjustment sleeve 10, and the other end is rotatably connected to the first scraper 1 or the second scraper 2.

[0041] In this embodiment, the second adjustment rod 8 is a screw, and the adjustment sleeve 10 is provided with an internal thread. A first rotation axis 11 is provided at the top or bottom of the adjustment sleeve 10. The end of the support rod 9 near the second adjustment rod 8 is rotatably connected to the rotation axis. A second rotation axis 12 is provided between the first scraper 1 and the second scraper 2. The first and second scraper 1 and 2 are rotatably connected to the second rotation axis 12. A mounting sleeve 13 is fixed in the middle of the second rotation axis 12 and rotatably sleeved on the end of the second adjustment rod 8. The first and second scraper 1 and 2 have an escape groove near the mounting sleeve 13 to enable rotation between the first and second scraper 1 and 2.

[0042] The snow scraper in this embodiment rotates the second adjusting rod 8 so that the adjusting sleeve 10 moves axially along the second adjusting rod 8, thereby changing the angle between the first scraper 1 and the second scraper 2, and finally adjusting the width of the entire snow scraper to adapt to roads of different widths and clear snow on roads of different widths.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
