Abstract

The invention relates to the field of road sweeping, in particular to a wingspan type road snow remover. The snow remover is characterized in that a bearing at the front end of the snow remover and a hydraulic power telescopic device connect two groups of snow shoveling fins into a large included angle-shaped machine, a snow shoveling protective cap (shovel) is arranged at the front end of the outer side of the included angle of the fins, the two groups of fins incline inwards in a trapezoidal closing-up shape from bottom to top, and the upper parts of the fins are arc-shaped and reversely bent outwards. Each group of fins consists of a plurality of wing sections which can be folded towards the inner side by a hydraulic power telescopic device; and the lower end of the inner side of each fin is provided with a wheel which is used for supporting a wing body and can be lifted and a brush-shaped roller which is used for cleaning accumulated snow. The snow cleaning machine is combined with a power machine through a power conversion device (a brush-shaped roller is arranged on the lower side) in front of the snow cleaning machine, so that a driver can complete various operations on the wingspan type road snow cleaning machine through an operation system on the power machine.

Description

Technical field

[0001] The invention relates to the field of road cleaning, in particular to a wingspan type road snow clearing machine. Background Art

[0002] There are many types of snow removal equipment available, including snowplows, roller-brush snowplows, push-type snow throwers, and railroad snow removal equipment. The snow removal width of these snowplows is often limited by the width of the power machinery they power, making a single pass insufficient for covering a wider area of the road surface. Wing-type road snowplows have yet to be developed. Summary of the Invention

[0003] In order to overcome the deficiencies of existing road snow-clearing machinery, the present invention provides a wing-span road snow-clearing machine. The technical solution adopted by the present invention is: the wing-span road snow-clearing machine is composed of a connecting bearing at the front end of the wing body and a hydraulic power telescopic device to connect the front end of two sets of wings together to form a large angle, and the rear part of the wing is free to open or close without restriction. An angled snow-clearing cap (shovel) or an oblique shovel-shaped snow-clearing cap (shovel) is installed on the outside of the front end of the wing angle to prevent the shoveled snow from entering the connecting bearing or the hydraulic power telescopic device at the connection between the two sets of wings and affecting the free opening and closing operation of the two sets of wings. The two sets of snow-clearing wings are trapezoidally closed from bottom to top and tilted inward to reduce the resistance during the snow-clearing process. The upper part of the wing is curved outward to prevent the shoveled snow from entering the inside of the wing angle. Each set of wings is composed of several sections that can be freely closed inwards, connected by a hydraulically powered telescopic device. The rear outer side of the front wing has a secondary snow-blocking wing that extends beyond the connection with the rear wing to prevent shoveled snow from entering the connection between the two wing sections and affecting the free closing of the rear wing. The lower end of the inner side of each set of wings is equipped with several wheels that support the wings and can be raised and lowered, as well as several brush-like cleaning rollers (to clean up residual snow that the snow-clearing wings did not clear). The brush-like cleaning rollers adjust their angles according to the opening angles of the two sets of wings and always rotate outward and backward to ensure that the cleared snow is ultimately swept to the outside of the rearmost edges of the two sets of wings. The wing-spanning road snow blower is combined with the power machinery that drives it through its front power conversion device. The driver controls the snow blower's various tasks through the control system on the power machinery. When a wing-type snow blower begins operation, the lifting wheels on the inner lower ends of the wings descend to maintain the minimum reasonable distance between the wings and the road being cleared. A hydraulically powered retractable mechanism at the front of the wings extends the two sets of wings to the desired width or their maximum width. The brush rollers adjust their angles with the wings, then rotate outward and rearward to fully contact the ground and begin clearing. The power mechanism propels the snow blower forward. Because the snow blower is angled, with a larger bottom and smaller top, it can clear snow to the outside and behind of the wings while reducing operational resistance. The outward-curving upper wings prevent scooped snow from entering the inner corner of the wings. Any snow not cleared by the wings is gradually swept outward by the brush rollers, thus clearing the entire road in one go. When encountering an obstacle or oncoming vehicle ahead, the wing-type road snow plow will flexibly adjust its angle or allow any section or multiple sections of a wing to close inward to avoid the obstacle. After avoiding the object, the hydraulic power retractable device at the angle of the wing body or the hydraulic power retractable device at a section of the wing body will extend the wing body or wing to continue working. If the road is in an urban road or highway with a central dividing strip, the left wing can be closed and the right wing can be used alone. The snow shovel cap can be replaced with an extended right shovel type. If necessary, the right wing can be lengthened and a retractable support device connected to the power mechanism can be installed at the middle and rear of the wing to increase its stability during operation.Although the wing-type snow blower is relatively large, its flexible closure minimizes traffic disruption. This invention is suitable for clearing snow on roads, plazas, airports, and railways. It efficiently clears a wider area of road surface with limited machinery, saving on machinery and contributing to environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0005] The present invention is further described below in conjunction with the accompanying drawings. The wingspan-type road snow blower is combined with a power machine through a power conversion device 4 at the front. When the snow clearing work starts, the lifting wheels 5 at the lower ends of the two sets of snow-shoveling wings 2 are lowered to keep a reasonable distance between the two sets of wings 2 and the road surface. The brush-like roller 6 is fully in contact with the ground and the angle is adjusted. The wing angle formed by the two sets of wings 2 is extended to a sufficient width by the hydraulic power telescopic device 2-2 at the front end to achieve full coverage of the cleaned road surface as much as possible. Since the two sets of wings 2 are formed at a large angle by the connecting bearing 3 at the front end and the hydraulic power expansion and contraction device 2-2, when the snow is moved forward under the power of the power machine, the snow will be cleared and shoveled along the outer side of the wings 2 to the rear of the outer side of the wings. The two sets of snow-clearing wings 2 form a trapezoidal wing angle with an upward closing shape and the upper part is bent outward, which reduces the resistance of the snow clearing machine to the advance. The snow shoveled will not enter the inner side of the wing angle. The brush roller 6 below the power conversion device 4 and the brush roller 6 at the inner lower end of the wing 2 will further clean the remaining snow and rotate outward and backward along the brush roller 6 to sweep it to the rear outer side of the wing 2, achieving the purpose of one-time full coverage and clearing of the snow on the road. When the wingspan type road snow clearer is working, if there is an obstacle or an oncoming vehicle in front, the main wing or segmented wing 2 will shrink and close inward by the hydraulic power expansion and contraction device 2-2 inside itself, reducing its own width to avoid the obstacle or oncoming vehicle. Because the front end of the wing corner is equipped with a snow-clearing cap 1 and the rear outer side of the front wing of each set of wings 2 is equipped with a snow-proof secondary wing 2-1, the snow picked up by the snow blower during operation will not enter the hydraulic power retractable device 2-2 of the nose, nor will it enter the gap between the two wing sections 2, and will not affect the free closing of the main wing and each wing section 2. When the wing-spanning road snow blower finishes its work, the main wing and each wing section 2 are closed inwardly by the hydraulic power retractable device 2-2 inside, and the lifting support wheel 5 raises the wing 2 and the brush roller 6 off the ground, completing the cleaning work.
