Description

Technical Field

[0001] The invention relates to a propeller type fan shovel and a road snow-clearing and ice-removing machine, belonging to the technical field of snow-clearing and ice-removing equipment. Background Art

[0002] In low temperature environments, snow may freeze into a hard layer of ice, especially snow that has been compacted or repeatedly frozen. The adhesion of hard snow or ice in the snow is very strong, and the ice-snow mixture is usually formed by snow and ice melting and refreezing. It has a higher density and complex composition structure. Compared with pure ice or snow, the ice-snow mixture is more difficult to remove because of its complex structure, with both the hardness of solid ice and the adhesion of wet snow. At the same time, the thickness, density, and degree of melting of the ice-snow mixture are uneven, making the removal work more difficult. The knives or brushes equipped with existing mechanical snow removal equipment are mainly used to remove loose snow, rather than the above-mentioned hard ice layers, hard snow blocks and ice-snow mixtures, so they cannot effectively handle compacted or frozen snow and ice layers.

[0003] Therefore, it is urgent to propose a novel propeller-type rotary shovel and road snow and ice clearing machine to solve the above-mentioned technical problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that ice, hard snow blocks and ice and snow mixtures are difficult to remove on winter roads.

[0025] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0026] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection is a non-detachable connection including but not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection and welding connection. The detachable connection includes but not limited to conventional detachable methods such as threaded connection, snap connection, pin connection and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can always be found in the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example: a fixed connection is selected as a welding connection, and a detachable connection is selected as a hinge connection.

[0027] Specific implementation method 1: Combination Figure 1-Figure 5 To illustrate the present embodiment, a propeller fan shovel of the present embodiment includes a propeller fan shovel 3 having a blade 31, and is characterized in that the blade 31 of the propeller fan shovel 3 becomes narrower from the outside to the inside, and a serration 32 is provided on the ground contacting side of the blade 31.

[0028] The propeller fan shovel 3 also includes a rotating shaft, which is rotatably mounted on the cross frame 4, the top of the rotating shaft is connected to the propeller fan shovel driving mechanism 5, and the bottom of the rotating shaft is equipped with fan blades 31.

[0029] The blade 31 of the propeller shovel 3 becomes narrower from the outside to the inside, and a serration 32 is provided on the ground contact side of the blade 31. The mass of the blade 31 from the outside is greater than the mass of the inside. The serration 32 becomes smaller from the outside to the inside, and a flat blade 33 is provided on the ground contact side of the blade 31 located inside the serration 32. With such a design, its kinetic energy is also the largest on the outside, so as to maintain sufficient vector force kinetic energy when the outside first contacts the stubborn ice and snow; the serration 32 on the ground contact becomes smaller from the outside to the inside, and is designed as a flat blade when it reaches the inside. When removing stubborn ice and snow, the largest serration 32 on the outside is contacted first. The larger serration 32 can break the ice and snow and penetrate into the bottom. At the same time, the relatively smaller serration 32 and the flat blade 33 on the inside can more thoroughly remove ice and snow debris.

[0030] The propeller blade 3 adopts a forged integrated structure to increase stability and blade body strength, and may also adopt a combined structure to facilitate replacement of damaged blades 31 and other components.

[0031] The fan blades 31 have an inclined slope α, which ranges from 5 to 80°. This will generate a downward vector force, allowing the fan blades 31 to penetrate into the lower part of the stubborn ice and snow to the interface between the ice and snow and the road surface, making the removal more thorough. At the same time, the centrifugal force generated by the rotation of the fan blades 31 will lift the ice and snow debris shoveled by the fan blades 31 backward, upward and outward.

[0032] The working surface of the blade 31 is not straight to the axis, but in the form of a tangent to the center of the circle, and maintains a certain arc backward with the direction of rotation to increase centrifugal force and torque and reduce resistance. Figure 1 As shown, so that there are no gaps on the working surface.

[0033] The rear edge of the fan blade 31 is designed with a vertical surface 34 with a height of about 5 cm, so as to carry the ice and snow debris scooped up by the fan blade 31 to the rear guide scraper, so that it can be discharged from the two sides or the rear of the vehicle in the direction regulated by the guide scraper 7 for collection and cleaning, or directly collected and cleaned using a winch.

[0034] The propeller blades 3 are used in pairs, and each pair of propeller blades 3 rotates inwards and in opposite directions when rotating.

[0035] Specific implementation method 2: Combination Figure 1-Figure 5 To illustrate the present embodiment, a propeller fan shovel road snow and ice clearing machine of the present embodiment is realized by relying on the propeller fan shovel described in the specific embodiment 1, which includes a main vehicle 1, a support arm 2, a propeller fan shovel 3 and a propeller fan shovel driving mechanism 5. The propeller fan shovel 3 is rotatably installed on one side of the main vehicle 1 through the support arm 2, and the propeller fan shovel driving mechanism 5 drives the propeller fan shovel 3 to rotate.

[0036] The main vehicle 1 is a traction mechanism and can be a large engineering vehicle. In other application environments, other travel modes can also be used, such as a small thermal engine and human propulsion. The power provided by the engineering vehicle or various other engines such as thermal engines and motors is used to drive the propeller fan shovel type road snow and ice clearing machine to remove stubborn ice and snow through the fan blades of the fan shovel.

[0037] A guide scraper 7 is provided on the support arm 2 located at the front side or the rear side of the propeller blade 3 .

[0038] There are two supporting arms 2, and the supporting arms 2 and the cross frame 4 are connected by multiple triangular or cross steel structure "ribs" to ensure the stability of the main structure. The propeller fan 3 is rotatably installed on the supporting arm 2 through the cross frame 4. An auxiliary wheel structure 6 is provided at the end of the supporting arm 2 to assist in supporting the supporting arm 2.

[0039] The support arm 2 is detachably fixed to the main vehicle 1 and can be lifted upward by the hydraulic system of the main vehicle to lift the propeller fan shovel off the ground so that the main vehicle can move quickly when no ice and snow clearing operations are being performed.

[0040] The size of the support arm 2 should be compatible with mainstream engineering vehicles on the market to enhance its applicability.

[0041] The installation position of the guide scraper 7 in actual operation can be flexibly designed. For example, it can be positioned farther back than the propeller fan shovel 3, in the shape of a "person", or in the shape of a "left stroke" of the "person" character, arranged from the right front to the left rear, or in the shape of a "right stroke" from the left front to the right rear, so as to guide the ice and snow residue to one side of the forward direction, which is convenient for subsequent cleaning.

[0042] Driven by the propeller fan shovel driving mechanism 5, the propeller fan shovel 3 starts to rotate at a relatively high speed. Under the pressure of its own gravity, the ground where the blades 31 touch the stubborn ice and snow. The blades 31 of the propeller fan shovel 3 use the kinetic energy generated by the rotation of the propeller and use the serrations 32 on the ground where the blades 31 touch the ground and the flat blade 33 to start to shovel away the ice and snow.

[0043] The guide scraper 7 is an arc-shaped plate, which is used in pairs with propeller fan shovels 3. Each pair of arc-shaped plates gradually opens from the center of each pair of propeller fan shovels 3 to the left and right sides. This design is a "dual machine" mode, and the two propeller fan shovels 3 can be used to rotate inward in opposite directions to avoid generating deflection force, which may cause machine instability or deviation in travel direction.

[0044] A more preferred technical solution can set the "single machine" or "multiple machine" modes according to the needs of the situation, that is, the specific number of propeller fan shovels 3, and the setting of the diameter, shape, material, weight, etc. of the fan blades 31. For example, large-scale flat roads such as airports can use large machinery or a "multiple machine" combination. Locations such as street intersections, traffic lights, alleys and doorways are small but always prone to stubborn ice and snow. A "single machine" or a small "double machine" combination can be used. It is suitable for clearing stubborn ice and snow in most cold areas in the north, airports, highways, large drying yards, parking lots, blocks, traffic lights, shopping malls and store entrances and other venues, and can also be exported to high-altitude cold regions abroad.

[0045] The propeller blade driving mechanism 5 can be a pneumatic engine, such as Figure 2As shown, the pneumatic engine is fixedly mounted on the cross frame 4, and its output end is connected to the top of the rotating shaft of the propeller fan shovel 3. The main vehicle 1 is used to generate high-pressure gas, and the high-pressure gas is transported into the pneumatic engine through the high-pressure air pipe. The pneumatic engine drives the propeller fan shovel 3, which is also fixed on the cross frame 4, to start rotating rapidly to remove stubborn ice and snow, and then the guide scraper 7 guides the ice and snow debris to both sides of the vehicle for further cleaning.

[0046] In a more preferred technical solution, the propeller fan drive mechanism 5 can be a belt drive structure, such as Figure 3 As shown, a driving motor is installed on the main vehicle 1, a driving pulley is provided at the output end of the driving motor, a driven pulley is installed on the rotating shaft of the propeller fan shovel 3, the driving pulley and the driven pulley are connected by a transmission belt, the driving motor drives the driven pulley to rotate through the driving pulley, and the driven pulley drives the propeller fan shovel 3 to rotate.

[0047] A more preferred technical solution is as follows: Figure 4 As shown, the propeller fan shovel driving mechanism 5 can be a driving structure combining helical gears and belt transmission, that is, a driving motor is installed on the vehicle 1, and a driving pulley is arranged at the output end of the driving motor. An auxiliary rotating shaft is rotatably installed on the cross frame 4, and a driven pulley is installed on the auxiliary rotating shaft. The driving pulley and the driven pulley are connected by a transmission belt, and driving helical gears are arranged at both ends of the auxiliary rotating shaft. A driven helical gear is arranged on the top of the rotating shaft of the propeller fan shovel 3, and the driving helical gear and the driven helical gear are meshed. The driving motor drives the driven pulley to rotate through the driving pulley, and the driven pulley drives the auxiliary rotating shaft to rotate. The auxiliary rotating shaft drives the driving helical gear to rotate, and the driving helical gear drives the driven helical gear to rotate, and the driven helical gear drives the propeller fan shovel 3 to rotate.

[0048] The auxiliary wheel structure 6 is connected to the support arm 2 by a limiting bolt, and a limit spring with adjustable height is arranged at the connection point. A certain gap is maintained between the two, so that the propeller fan shovel 3 can retain a certain room for up and down movement according to the terrain, preventing hard contact with the road surface, damaging the road surface or seriously wearing the serrated blade surface, damaging the fan blade 31 or even damaging the entire machine.

[0049] It also includes a protective cover 8, the rear end of which is connected to the support arm 2 by a hinge and can be opened from the front end to facilitate inspection, troubleshooting of mechanical failures, replacement of parts, etc.

[0050] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be arranged and combined, and those skilled in the art can exhaust all possibilities based on the mathematical knowledge of arrangement and combination. Therefore, the present invention will no longer describe the technical solutions after arrangement and combination one by one, but it should be understood that the technical solutions after arrangement and combination have been disclosed by the present invention.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
