The present disclosure generally relates to the technical field including a snowplow apparatus applicable to engineering machinery and, more particularly, relates to a side snowplow including a land leveler.
Land levelers, when used as snowplow tools, may have the following features: being widely applicable, requiring relatively low working space, having relatively high working speed, having relatively strong adaptability. However, the snow plowing efficiency of a land leveler is lower than the snow plowing efficiency of a professional snowplow. A large professional snowplow is often expensive and is left unused for a long period of time during a year. Owning a professional snowplow can cause a waste of resources.
In recent years, land levelers are used more and more to remove snow. In some applications, a professional snow plowing device is used with a land leveler to remove snow. In some other applications, the blade of a snowplow is used directly to remove snow. Currently, various different snow plowing devices can be mounted on land levelers to remove snow. A snow plowing device may have a bar shape or a āVā shape. For example, a Chinese patent with the publication number CN103061299A discloses that, a snow plowing device is mounted on the front rack of a land leveler. As a result, a large overlapping area is formed between the snow-removing region and the blade. The actual plowing width of the land leveler is not expanded.
When removing accumulated snow, it is desired that the distance between the blade and the road surface is sufficiently close to ensure snow is properly removed. However, hard protrusions, e.g., cracking areas on the road surface, and protruded areas formed after road repair, can exist on the road surface, and those hard protrusions can cause significant damages to the blades. Such snow plowing method can also cause significant damages to the road surface.
It has been well known that, land levelers are mainly driven by a rear-wheel drive system. Because a land leveler often has a long body, 70% of its total weight is applied on the rear wheels of the land leveler. Such structure, which is light on the front portion and heavy on the rear portion of the body, can enable the land leveler to be more stable on wet roads. If a snow plowing device is mounted at the front portion of the land leveler, the center of gravity of the land leveler can shift closer to the front portion of the land leveler. Because of the wet icy roads, the land leveler is more susceptible to skidding and being unstable. Further, the snow plowing device mounted at the front portion of a land leveler may also block the driver's field of view.
To solve the above technical problems in the conventional technology, the present disclosure provides a side snowplow including a land level. In a snow plowing process, the plowing width can be expanded for a single trip, and snow plowing process may be more efficient. Further, the disclosed side snowplow may be less susceptible to skidding on an icy road. The body of the disclosed side snowplow may be less susceptible to swaying. The driver's field of view would not be blocked such that it is easier for the driver to steer the side snowplow and avoid barriers on the road.
The present disclosure provides a side snowplow including a land leveler, including: a rear mounted seat, a hydraulic cylinder I, a pull rod, a snow-pushing board, an oscillating rod, a hydraulic cylinder II, and a front mounted seat. The rear mounted seat is fixed on a rear portion of a rear rack of the land leveler, the rear mounted seat being hingedly connected to a hinge plate I through pins. One end of the pull rod is hingedly connected to the hinge plate I through pins, and another end of the pull rod is hingedly connected to a hinge plate II through fixed pins. One end of the hydraulic cylinder I is hingedly connected to the rear mounted seat, and another end of the hydraulic cylinder I is hingedly connected to the pull rod. The front mounted seat is fixed on a front portion of the rear rack of the land leveler. One end of the oscillating rod is hingedly connected to the front mounted seat, and another end of the oscillating rod is hingedly connected to a hinge plate III through the pins. One end of the hydraulic cylinder II is hingedly connected to the front mounted seat, and another end of the hydraulic cylinder II is hingedly connected to the oscillating rod. The snow-pushing board is positioned at a left side or a right side of the land leveler and inclines toward a direction that the land leveler moves, a rear end of the snow-pushing board being connected to the hinge plate II, and a front end of the snow-pushing board being connected to the hinge plate III.
The present disclosure includes several advantages.
Firstly, in conventional technology, the snow-pushing board is mounted on the front portion of a snowplow. Because the width of the front portion of the snowplow is limited, the width of the snow-pushing board is limited. In the present disclosure, the snow-pushing board may be mounted on the left side or the right side of a land leveler. The width of the snow-pushing board can be greatly increased. The snow-pushing board may incline to a front portion of the land leveler. During a snow plowing process, the plowing width can be expanded in a single trip, which allows the disclosed side snowplow to be used in various high-grade highways, airports, and urban and rural roads.
Secondly, the pull rod of the disclosed side snowplow may be contracted. During a snow plowing process, the land leveler may move forward. When the blade scratches a protruded stiff object on the road surface, the pull rod may retract such that the snow-pushing board may be raised up to cross the protruded portion. Thus, the pull rod may buffer the scratching, and reduce the damages on the blade and the road surface. The pull rod may also be used to avoid barrier objects.
Thirdly, the present disclosure may be entirely positioned at the left side or the right side of a land leveler such that the driver's field of view may not be blocked. The disclosed side snowplow may be mounted on the rear rack of the land leveler so that the center of gravity of the disclosed snowplow may not shift forward. The disclosed side snowplow may be less susceptible to skidding on an icy road. The body of the disclosed side snowplow may be less susceptible to swaying.
Fourthly, the lifting mechanism of the snow-pushing board in the disclosed side snowplow may have a compact, simple, and practical structure. A small moving distance of the cylinder may result in a relatively high lifting of the snow-pushing board. The blade may effectively avoid a barrier object.

Further, the sliding rod 19 may include a spring 18. The spring 18 may be compressed between the steel tube 13 and the sliding rod 19. When the snow-pushing board 7 scratches a protruded stiff object on the road surface, the sliding rod 19 may slide in the steel tube 13, and the spring 18 may be compressed. The spring 18 may buffer the scratching between the snow-pushing board 7 and the road surface.

Further, the hinge plate II 6 may be configured with two fixed pins 5 to prevent the snow-pushing board 7 from swaying.
