Description

Technical Field

[0001] This invention belongs to the technical field of road ice and snow removal equipment, and in particular relates to a roller-type road ice and snow removal device. Background Technology

[0002] Road ice and snow are one of the main factors affecting traffic safety in winter, especially in cold regions where snow and ice form a dense layer after being compacted by vehicles, making it difficult to remove with conventional cleaning equipment. Currently, commonly used road de-icing and snow removal devices mainly include snowplows, ice-breaking rollers, de-icing agent spreading equipment, and combined de-icing vehicles.

[0003] Among them, roller icebreakers are widely used due to their strong continuous operation capability and high working efficiency. Existing roller icebreakers typically employ a structure with blades, toothed plates, or steel brushes rigidly fixed to the surface of the roller. The rotation of the roller drives these rigid components to impact or cut the ice layer, achieving crushing and cleaning. However, such devices still have the following shortcomings in practical use: 1. Poor adaptability and easy to damage the road surface: Rigid fixed blades or toothed plates cannot adapt to road surface undulations and protrusions such as road markings, manhole covers, expansion joints, etc. While breaking ice, they are easy to scratch or damage the road structure, and may even cause the blades to break. 2. Limited adaptability to ice thickness: Existing devices mostly use a single type of crushing component, making it difficult to effectively handle both thick and thin ice layers. Thick ice requires high impact force, while thin ice requires fine crushing. A single component often fails to break thick ice and easily damages the road surface when handling thin ice. 3. The separation of sweeping and crushing results in low work efficiency: Most devices only have the crushing function. The remaining ice on the road surface requires additional sweeping equipment or multiple operations, resulting in high equipment investment, high energy consumption, long working time, and easy to cause road congestion. 4. High maintenance costs: Rigid components are easily damaged under long-term impact, and most of them are integrally welded or bolted structures. Replacement requires disassembling the entire roller body or a large number of parts, resulting in long maintenance cycles and high costs. 5. Large impact reaction force, affecting the overall life of the machine: The transient reaction force generated when the rigid blade hits the ice layer is directly transmitted to the drive shaft and frame, accelerating the fatigue damage of bearings, reducers and transmission systems.

[0004] Therefore, there is a need for a road ice and snow removal device that can efficiently break up ice layers of different thicknesses, adapt to uneven road surfaces, and has a sweeping function while being easy to maintain. Summary of the Invention

[0005] In view of this, the present invention aims to propose a roller-type road ice and snow removal device to solve the problems of poor adaptability, single adaptability to ice thickness, low operating efficiency, high maintenance cost and reduced overall machine life of existing roller-type ice breaking devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a roller-type road ice and snow removal device, comprising a roller body and functional parts. The roller body includes two opposite and spaced-apart end caps, which are connected by multiple connecting rods. The multiple connecting rods are evenly spaced circumferentially between the two end caps. Each connecting rod is provided with a functional part, which includes a first blade part, a second blade part, a steel brush part, and a hammer ball part. The functional parts on the same connecting rod are of the same type. The first blade part includes multiple first blade assemblies evenly spaced along the length of the connecting rod. The second blade part includes multiple second blade assemblies evenly spaced along the length of the connecting rod. The steel brush part includes multiple steel brush assemblies evenly spaced along the length of the connecting rod. The hammer ball part includes multiple hammer ball assemblies evenly spaced along the length of the connecting rod. The first blade assembly, the second blade assembly, the steel brush assembly, and the hammer ball assembly are all rotatably connected to the connecting rod.

[0007] Furthermore, the first blade assembly includes two connecting plates and a plurality of first blades. The two connecting plates are arranged opposite to each other and spaced apart. One end of the two connecting plates is rotatably connected to a connecting rod, and the other ends of the two connecting plates are connected to each other by a connecting shaft. The plurality of first blades are rotatably mounted on the connecting shaft.

[0008] Furthermore, the second blade assembly includes a first connecting rope and a plurality of second blades, one end of the first connecting rope being rotatably connected to a connecting rod, and the plurality of second blades being connected to the other end of the first connecting rope.

[0009] Furthermore, the steel brush assembly includes a second connecting rope and a brush head, one end of the second connecting rope being rotatably connected to a connecting rod, and the other end of the second connecting rope being connected to the brush head.

[0010] Furthermore, the hammer assembly includes a third connecting rope and a plurality of hammers, one end of the third connecting rope being rotatably connected to the connecting rod, and the other end of the third connecting rope being connected to a plurality of hammers.

[0011] Furthermore, the first connecting rope, the second connecting rope, and the third connecting rope are all made of flexible steel rope.

[0012] Furthermore, both ends of the connecting rod are connected to the end caps via nuts.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides a roller-type road ice and snow removal device. The functional parts include a first blade part, a second blade part, a steel brush part, and a hammer ball part. The first blade part is used to break thicker ice layers, the second blade part is used to break thinner ice layers, and the hammer ball part is used to hammer the ice surface, assisting the first and second blade parts to break the ice layer more effectively. The steel brush part is used to sweep and collect the snow layer, ice fragments after the ice layer is broken, and ice-water mixture on the road surface. The four functional parts work together to realize the graded breaking and cleaning of the device, and achieve efficient treatment of ice layers of different thicknesses. 2. The roller body and functional components of the present invention are detachable modular structures, which can be individually disassembled and replaced if damaged, greatly saving the cost of device maintenance and upkeep. 3. The second blade assembly, steel brush assembly and hammer ball assembly in this invention are connected by a flexible steel rope. The flexible rope structure allows the blade, hammer ball and brush head to adaptively adjust their angle and position when encountering road bumps or potholes, reducing rigid impact damage. When the roller body rotates, the flexible steel rope and its end parts are thrown out radially under the action of centrifugal force, obtaining a high linear velocity. The additional kinetic energy provided by centrifugal force effectively improves the crushing and sweeping ability of the functional part. 4. The present invention can select and assemble different types of functional parts according to the actual road conditions. The device is highly flexible. Different types of functional parts are alternately arranged along the circumference of the roller body. The roller can sequentially achieve thick ice breaking, thin ice breaking, hammering assistance and ice sweeping on the road surface in one rotation. No multiple operations or additional equipment are required, which greatly improves the efficiency of de-icing and snow removal. 5. The flexible rope structure in this invention can absorb part of the impact reaction force generated when the blade or hammer ball hits the ice layer, reducing the transient load transmitted to the connecting rod, end cap and drive system, thereby reducing the failure rate of bearings and transmission system and extending the service life of the device.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0017] See Figure 1-5 This embodiment describes a roller-type road ice and snow removal device, which includes a roller body and a functional part. The roller body includes two opposite and spaced-apart end caps 1. The two end caps 1 are connected by a plurality of connecting rods 2. The plurality of connecting rods 2 are evenly spaced circumferentially between the two end caps 1. Both ends of the connecting rods 2 are connected to the end caps 1 by nuts, which facilitates disassembly and assembly.

[0018] In this embodiment, the roller-type road ice and snow removal device is installed on a snow removal vehicle or traction equipment via the roller body, and the roller body is driven by a power source to rotate at high speed around its axis.

[0019] The connecting rod 2 is provided with functional parts, including a first blade part, a second blade part, a steel brush part, and a hammer ball part. The functional parts on the same connecting rod 2 are of the same type. The first blade part includes a plurality of first blade assemblies 3 evenly spaced along the length of the connecting rod 2. The second blade part includes a plurality of second blade assemblies 4 evenly spaced along the length of the connecting rod 2. The steel brush part includes a plurality of steel brush assemblies 5 evenly spaced along the length of the connecting rod 2. The hammer ball part includes a plurality of hammer ball assemblies 6 evenly spaced along the length of the connecting rod 2. The first blade assembly 3, the second blade assembly 4, the steel brush assembly 5, and the hammer ball assembly 6 are all rotatably connected to the connecting rod 2. Different types of functional parts can be installed on different connecting rods 2 along the circumference of the roller body. For example, a first blade assembly 3 can be installed on one connecting rod 2, a second blade assembly 4 can be installed on the adjacent connecting rod 2, a steel brush assembly 5 can be installed on the next adjacent connecting rod 2, and a hammer ball assembly 6 can be installed on the next connecting rod 2, and so on, in an alternating manner.

[0020] This embodiment can select and assemble different types of functional parts according to the actual road conditions. The device is highly flexible. Different types of functional parts are alternately arranged along the circumference of the roller body. The roller can sequentially achieve thick ice breaking, thin ice breaking, hammering assistance and ice sweeping on the road surface in one rotation. No multiple operations or additional equipment are required, which greatly improves the efficiency of snow and ice removal.

[0021] The functional units described in this embodiment include a first blade unit, a second blade unit, a steel brush unit, and a hammer ball unit. The first blade unit is used for breaking thicker ice layers, the second blade unit is used for breaking thinner ice layers, and the hammer ball unit is used to hammer the ice surface, assisting the first and second blade units in breaking the ice layer more effectively. The steel brush unit is used to sweep and collect the snow layer on the road surface, the broken ice fragments, and the ice-water mixture. The four functional units work together to achieve graded breaking and cleaning of the device, realizing efficient processing of ice layers of different thicknesses.

[0022] In this embodiment, the first blade assembly 3 includes two connecting plates 7 and a plurality of first blades 8. The two connecting plates 7 are arranged opposite to each other and spaced apart. One end of the two connecting plates 7 is rotatably connected to the connecting rod 2, and the other ends of the two connecting plates 7 are connected by a connecting shaft. The plurality of first blades 8 are rotatably arranged on the connecting shaft. The first blades 8 can rotate freely around the connecting shaft. The first blade assembly 3 adopts a rigid blade hinge form for powerful crushing of thicker ice layers.

[0023] In this embodiment, the second blade assembly 4 includes a first connecting rope 9 and a plurality of second blades 10. One end of the first connecting rope 9 is rotatably connected to the connecting rod 2, and the plurality of second blades 10 are connected to the other end of the first connecting rope 9. When the roller body rotates, the second blades 10 are thrown outward under the action of centrifugal force to break thinner ice layers.

[0024] In this embodiment, the steel brush assembly 5 includes a second connecting rope 11 and a brush head 12. One end of the second connecting rope 11 is rotatably connected to the connecting rod 2, and the other end of the second connecting rope 11 is connected to the brush head 12. The brush head 12 is in close contact with the road surface under the action of centrifugal force, and is used to sweep and collect the snow layer and ice fragments after the ice layer is broken.

[0025] In this embodiment, the hammer ball assembly 6 includes a third connecting rope 13 and a plurality of hammer balls 14. One end of the third connecting rope 13 is rotatably connected to the connecting rod 2, and the other end of the third connecting rope 13 is connected to a plurality of hammer balls 14. The hammer balls 14 hammer the ice surface under the action of centrifugal force, assisting the first blade part and the second blade part to break the ice layer more effectively.

[0026] In this embodiment, the first connecting rope 9, the second connecting rope 11, and the third connecting rope 13 are all made of flexible steel rope. Flexible steel rope has the characteristics of high strength, wear resistance, and a certain degree of flexibility. The second blade assembly 4, the steel brush assembly 5, and the hammer ball assembly 6 are connected by flexible steel rope. The flexible rope structure allows the blade, hammer ball, and brush head to adaptively adjust their angle and position when encountering road bumps or potholes, reducing rigid impact damage. When the roller body rotates, the flexible steel rope and its end components are thrown radially under the action of centrifugal force, obtaining a high linear velocity. The additional kinetic energy provided by centrifugal force effectively improves the crushing and sweeping capabilities of the functional parts.

[0027] The flexible rope structure in this embodiment can absorb part of the impact reaction force generated when the blade or hammer ball 14 hits the ice layer, reducing the transient load transmitted to the connecting rod, end cap and drive system, thereby reducing the failure rate of bearings and transmission system and extending the service life of the device.

[0028] In this embodiment, the roller body and functional components are detachable modular structures, allowing damaged components to be disassembled and replaced individually, which greatly saves on equipment maintenance and repair costs.

[0029] The working process of this embodiment includes the following steps: Step 1: Preparation stage: Based on the actual road conditions and ice thickness, select the appropriate type and quantity of functional components, rotate and install them on the corresponding connecting rods, fix the connecting rods with different functional components between the two end caps 1 with nuts to form a complete roller body, install the roller body on the snow removal vehicle or traction equipment, and connect it to the power drive system. Step 2: Start-up and rotation: Start the power source to drive the roller body to rotate at the set speed, and the functional components gradually unfold outward under the action of centrifugal force; Step 3: Ice breaking stage: The first blade assembly 3 first contacts the thicker ice layer. The rigid blade cuts into the ice layer with greater kinetic energy, breaking the thick ice into large ice fragments. Subsequently, the second blade assembly 4, under the action of centrifugal force, throws out the second blade to break the remaining thin ice layer a second time, forming small ice fragments. The hammer ball assembly 6 strikes the ice surface synchronously or alternately, loosening the adhesion between the ice layer and the road surface, further improving the breaking effect. Step 4: Sweeping and collecting stage: Under the action of centrifugal force, the steel brush assembly 5 makes the brush head 12 stick to the road surface, sweeping the broken ice and snow along the rotation direction to one side of the roller or into the collection box of the snow removal vehicle, which is convenient for subsequent collection or pushing. Step 5: Maintenance and Replacement: After the operation is completed or if a component is found to be damaged, the nut can be loosened and the corresponding connecting rod 2 can be removed. The damaged blade, brush head 12, hammer ball 14 or flexible rope assembly can be replaced individually without disassembling the entire roller body.

[0030] In this embodiment, if only a thin ice layer is encountered during the ice breaking stage, only the second blade assembly 4 needs to perform the breaking work.

[0031] In this embodiment, when encountering road bumps or hard objects during the ice breaking and cleaning / collection stages, the blades, hammers, or brush heads connected by the flexible rope automatically swing back or deflect to avoid obstacles. After passing through, they return to their working position under centrifugal force, thereby protecting the road surface and the device.

[0032] The embodiments of the present invention disclosed above are merely illustrative of the invention. These embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
