Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of road snow removing equipment, in particular to a front and rear protection device of a rotating mechanism. BACKGROUND

[0002] In the ice breaking and snow removing machine, the auger side discharge device mainly consists of auger blades, a transmission shaft, a driving motor (or a hydraulic motor) and a discharge port. The auger blades are a spiral metal structure, usually made of high-strength and corrosion-resistant steel, which rotates around the transmission shaft. The transmission shaft is connected to the driving motor or the hydraulic motor through a shaft coupling, and the auger blades are driven to rotate by the power source. The discharge port is located on one side of the auger and is connected to the spiral channel of the auger blades, which is used to discharge the ice and snow pushed by the auger to the roadside or designated collection area. The ice scraper is behind the auger side discharge device, which can first collect and push part of the snow and ice using the auger side discharge device to reduce the amount of ice and snow on the road surface.

[0003] Chinese invention patent (application number 202411207099.2) discloses a multifunctional ice breaking and snow removing vehicle. The front hanging rack can load a snow shovel or a snow brush to clean the accumulated snow on the road, ensuring smooth traffic. The middle ice breaking device breaks hard ice and snow. The rear ice scraping shovel and the auger side discharge function discharge the broken ice. The rear blowing device cleans the remaining ice and snow again. This invention can choose multifunctional snow removing combination according to different road conditions, greatly improves the snow removing efficiency, and makes up for the shortcomings of single operation of conventional snow removing vehicles.

[0004] In the above scheme, the ice scraping shovel is directly fixed on the rear side of the auger to collect the broken ice residue after ice breaking. However, the ice scraping shovel is directly fixed below the chassis assembly, and the gap between the ice scraping shovel and the ground cannot be adjusted according to the actual situation, which may cause damage to the ice scraping shovel. In addition, foreign matters may enter the high-speed rotating auger during operation, causing damage to the auger.

[0005] The information disclosed in this background section is only intended to increase the understanding of the general background of the present utility model, and should not be considered as acknowledging or implying in any form that the information constitutes prior art known to those skilled in the art. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims to provide a front and rear protection device of a rotating mechanism, which can prevent foreign matters from entering the high-speed rotating side discharge rotating mechanism, avoid damage to the rotating mechanism, reduce maintenance cost, and improve the working life of the equipment.

[0007] To achieve the above objectives, this utility model provides a front and rear protection device for a rotating mechanism, which is installed on the icebreaker frame. The icebreaker frame is equipped with an ice-breaking wheel and a side-row rotating mechanism. The front and rear protection device includes a front protective cover and a rear protective cover for the rotating mechanism, which are respectively disposed on the front and rear sides of the side-row rotating mechanism. The front protective cover is fixed to the icebreaker frame. The rear protective cover is rotatably disposed on the icebreaker frame, with one end rotatably mounted on the icebreaker frame via a pivot shaft, and the other end fixed with a shovel blade. The rear protective cover is rotatably connected to one end of a hydraulic cylinder on its lower side, and the other end of the hydraulic cylinder is rotatably connected to the icebreaker frame.

[0008] In one or more embodiments, the front protective cover of the rotating mechanism can cover at least 50%-80% of the area of ​​the side-mounted rotating mechanism on the projection plane of the icebreaker in the direction of travel.

[0009] In one or more embodiments, the front protective cover of the rotating mechanism has an arc-shaped structure on the side near the side-row rotating mechanism, and its curvature is the same as that of the side-row rotating mechanism.

[0010] In one or more embodiments, the rear protective cover of the rotating mechanism has an arc-shaped structure on the side near the side-row rotating mechanism, and its curvature is the same as that of the side-row rotating mechanism.

[0011] In one or more embodiments, a blade protection mechanism is provided between the blade and the rear protective cover of the rotating mechanism. The blade protection mechanism is an arc-shaped structure, and the blade is fixed inside its arc surface to support the back of the blade.

[0012] In one or more embodiments, there are multiple rear protective covers for the rotating mechanism, which are arranged side by side on the rear side of the side-row rotating mechanism, and each rear protective cover for the rotating mechanism is connected to the icebreaker frame through a separate hydraulic cylinder.

[0013] Compared with existing technologies, the front and rear protection devices of the rotating mechanism according to this utility model not only prevent foreign objects from entering but also facilitate the efficient collection and guidance of snow and ice mixtures, reducing the risk of damage to the rotating mechanism and improving snow removal efficiency. The rear protection covers of the rotating mechanism are arranged side-by-side, each controlled by a separate hydraulic cylinder, allowing for independent angle adjustment. Their curved design can closely conform to different road conditions, greatly enhancing adaptability to complex road surfaces. Furthermore, the blade protection mechanism supports the blade from the back, effectively distributing pressure, reducing wear, extending blade life, lowering maintenance costs, and ensuring long-term stable operation of the equipment.

[0017] The specific implementation of the utility model is described in detail below in combination with the drawings, but it should be understood that the protection scope of the utility model is not limited by the specific implementation.

[0018] Unless otherwise explicitly indicated, in the whole specification and claims, the term "comprises" or its variants such as "contains" or "includes" and the like will be understood as including the stated element or component, without excluding other elements or components.

[0019] As Figure 1 shown, according to the front and back protection devices of a rotating mechanism according to an embodiment of the utility model, it is installed on the ice breaking machine frame body 1, the ice breaking machine frame body 1 is provided with ice breaking wheels and side discharge rotating mechanisms 3, which are respectively used for ice breaking operation on ice and snow road surface and cleaning ice and snow and their mixture to the side of the ice breaking machine, generally the right side. In the driving direction of the ice breaking machine, the ice breaking wheels are installed on the front side of the ice breaking machine frame body 1, and the side discharge rotating mechanisms 3 are installed on the middle position of the ice breaking machine frame body 1. In addition, according to actual needs, support wheels can be arranged on the rear side of the ice breaking machine frame body 1, which support the operation of the ice breaking machine, prevent the ice breaking machine from tilting due to excessive self-weight, and ensure the safe and stable operation of the ice breaking machine.

[0020] The front and back protection devices of a rotating mechanism according to the embodiment, including rotating mechanism front protection cover 2 and rotating mechanism rear protection cover 4, rotating mechanism front protection cover 2 and rotating mechanism rear protection cover 4 are all arranged on the ice breaking machine frame body 1, and are respectively arranged on the front side and the rear side of the side discharge rotating mechanism 3.

[0021] The rotating mechanism front protection cover 2 is fixed on the ice breaking machine frame body 1, preferably fixed by welding. The projection of the rotating mechanism front protection cover 2 on the driving direction of the ice breaking machine can cover at least 50%-80% of the area of the side discharge rotating mechanism 3, that is, the lowermost end of the rotating mechanism front protection cover 2 is located at the position of 50%-80% of the top end to the lowest end of the side discharge rotating mechanism 3. The side of the rotating mechanism front protection cover 2 close to the side discharge rotating mechanism 3 is arc-shaped structure, and the arc is the same as the side discharge rotating mechanism 3, so as not to hinder the operation of the side discharge rotating mechanism 3.

[0022] The main function of the rotating mechanism front protective cover 2 is to collect ice and snow and its mixture, and cooperate with the side discharge rotating mechanism 3 to effectively remove the ice and snow, and prevent foreign matters from entering the high-speed rotating side discharge rotating mechanism 3 to cause damage when the ice breaking machine is working.

[0023] The rotating mechanism rear protective cover 4 is rotatably arranged on the ice breaking machine frame body 1, one end of which is rotatably installed on the ice breaking machine frame body 1 through a pivot shaft, and the other end of which is fixed with a shovel blade. The rotating mechanism rear protective cover 4 is rotatably connected with one end of a hydraulic cylinder 5 at the lower side (at the position close to the shovel blade), and the other end of the hydraulic cylinder 5 is rotatably connected with the ice breaking machine frame body 1.

[0024] Similar to the rotating mechanism front protective cover 2, the side close to the side discharge rotating mechanism 3 of the rotating mechanism rear protective cover 4 is arc-shaped, and the arc is the same as that of the side discharge rotating mechanism 3, so as not to hinder the operation of the side discharge rotating mechanism 3.

[0025] The shovel blade protection mechanism 6 is arranged between the shovel blade and the rotating mechanism rear protective cover 4, and is fixed on the rotating mechanism rear protective cover 4. The shovel blade protection mechanism 6 is arc-shaped, and the arc surface is fixed with the shovel blade to support the back surface of the shovel blade and increase the thickness of the shovel blade. In actual operation, the ordinary shovel blade may be seriously worn in a short time when facing the ice layer containing sharp impurities and the road surface with gaps. However, the rotating mechanism rear protective cover 4 can significantly slow down the wear rate of the shovel blade, reduce the damage of the road surface gap to the shovel blade, reduce the maintenance cost, and prolong the service life of the shovel blade.

[0026] The hydraulic cylinder 5 is connected with the power source on the working vehicle, and can be driven by the hydraulic system to stretch to the working position and can be kept stationary, so that the rotating mechanism rear protective cover 4 cannot freely stretch during working, and the side discharge rotating mechanism 3 is protected.

[0027] The rotating mechanism rear protective cover 4 can be multiple, and is arranged side by side at the rear side of the side discharge rotating mechanism 3. Each rotating mechanism rear protective cover 4 is connected with the ice breaking machine frame body 1 through a separate hydraulic cylinder 5, so as to realize the close collection of ice and snow on the uneven road surface. During working, the hydraulic cylinder applies pressure to the shovel blade, and the shovel blade directly acts on the road surface, so as to achieve the purpose of concentrated collection of ice and snow and secondary crushing of ice and snow. The road surface ice and snow collected by the shovel blade can be discharged to the side through the side discharge rotating mechanism 3, so as to ensure that the ice and snow is quickly discharged to the side of the equipment, and ensure that the equipment continuously works without interruption.

[0028] In the utility model, on mountainous area or country road, the road surface presents complex concave-convex unevenness because of the terrain and icing condition, the protection cover 4 behind the rotating mechanism can collect ice and snow by closely adhering to the road surface according to the road surface condition by adjusting the angle and height of respective hydraulic cylinder.
