Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of road snow removal, and particularly relates to a multifunctional snow removal roller brush. BACKGROUND

[0002] Road snow removal is an important measure to ensure traffic safety and road smoothness, and the main purpose of road snow removal is to remove snow on the road, reduce traffic safety hazards caused by snow, and ensure normal traffic of vehicles and pedestrians. In areas where snow falls frequently or snowfall blocks roads in winter, road snow removal is particularly important. The role of snow removal vehicles in road snow removal mainly focuses on cleaning road snow, improving traffic safety, and cleaning outdoor snow. The snow removal roller brush is a key component of the snow removal vehicle. The snow removal roller brush rotates to push the snow to one side or the back, thereby achieving the purpose of removing road snow.

[0003] In current snow removal operations, the actual problem is that the surface of the snow removal roller brush gradually freezes when it is used to clean road snow, increasing the weight and resistance of the snow removal roller brush, making it difficult to push and rotate, and thus affecting the cleaning of road snow.

[0004] In the prior art, patent application No. 201821695763.2 discloses a snow removal roller brush connecting structure, which mainly includes a snow removal roller brush, a baffle support frame, a steering mechanism, and a universal wheel lifting mechanism. The baffle support frame is connected to the snow removal roller brush to increase the structural strength of the snow removal roller brush baffle, making the overall structure more solid and stable when the roller brush is working, and not easily damaged when encountering obstacles, thereby avoiding the problem of interference between the baffle and the roller brush caused by baffle deformation. Patent application No. 202221159369.3 discloses a new road snow removal roller brush, which uses a motor as a driving force to drive the roller brush to rotate, thereby sweeping the snow on the road into a loading bucket for collection. The utility model drives the stirring wheel to rotate when the roller brush rotates, so that the stirring wheel breaks the frozen snow, facilitating subsequent roller brush cleaning work. Patent application No. 202321158873.6 discloses a snow removal mechanism rod with a liftable snow removal roller brush. The snow removal roller brush universal wheel lifting mechanism can simultaneously control two universal wheels to lift synchronously, thereby optimizing the stability of the universal wheel supporting the equipment. When adjusted to the appropriate height, the screw pin is set to position the screw rod at the appropriate position to prevent it from rotating and increase the stability of the equipment operation, achieving the effect of conveniently and quickly adjusting the height of the roller brush.

[0005] The three existing technologies mentioned above have successively solved the problems of interference, collection and fragmentation, and stability. In response to the existing problems of snow removal rollers freezing, and in line with the development trend of intelligent and automated systems, a multifunctional and efficient snow removal roller is urgently needed in this field.

[0027] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 7As shown in the figure, an embodiment of the present invention provides a multifunctional snow removal roller brush, including a main frame 1, a snow removal roller brush 2 and two connecting columns 3.

The adjustment device 8 is fixedly connected to the front side of the main frame 1.

[0030] The above solution involves setting up an ice-removing device 5 to remove the ice remaining on the road surface after the snow removal roller brush 2 has been cleaned, thus preventing pedestrians or vehicles from slipping due to the ice residue.

[0031] refer to Figure 3 , Figure 6 and Figure 7 The adjusting device 8 includes two limiting blocks 801, a fixing block 802, an electric cylinder 803, and a mounting plate 804. The two limiting blocks 801 are fixedly connected to the front side of the main frame 1 and are located on the left and right sides of the stroke hole 4. The surfaces of the two limiting blocks 801 are provided with grooves 9 at equal intervals. The fixing block 802 is located between the two limiting blocks 801, and the rear side of the fixing block 802 is fixedly connected to the front side of the pressure rod 501. The mounting plate 804 is fixedly connected to the front side of the main frame 1. The electric cylinder 803 is fixedly connected to the bottom of the mounting plate 804. The fixing block 802 has a cavity 10 inside, and a lifting mechanism 11 is provided inside the cavity 10. The output end of the electric cylinder 803 is fixedly connected to the lifting mechanism 11 inside the fixing block 802.

[0032] The above solution is adopted: by setting the adjustment device 8, the lifting mechanism 11 can be moved, thereby adjusting the position of the ice-shoveling device 5.

[0033] refer to Figure 7The lifting mechanism 11 includes a second compression spring 1101, two transmission blocks 1102, two insert plates 1103, two pairs of push columns 1104, two connecting rods 1105, and a pressing rod 1106. The two transmission blocks 1102 are respectively fixedly connected to the left and right ends of the second compression spring 1101, and the two insert plates 1103 are respectively fixedly connected to the sides of the two transmission blocks 1102 that are far apart from each other. The other end of the insert plate 1103 passes through the surface of the fixing block 802 and extends to the limiting block 801. Inside the groove 9 on the surface, inclined grooves 12 are provided on both the front and rear sides of the two transmission blocks 1102. Two pairs of push columns 1104 are respectively set on the inner wall of the inclined grooves 12 on the surface of the two transmission blocks 1102. Two connecting rods 1105 are respectively fixedly connected to the front and rear sides of the two pairs of push columns 1104. The pressing rod 1106 is fixedly connected to the top of the two connecting rods 1105, and the top of the pressing rod 1106 penetrates the surface of the fixing block 802 and is fixedly connected to the output end of the electric cylinder 803.

[0034] By adopting the above solution, the position of the ice-shoveling device 5 can be adjusted by setting up the lifting mechanism 11, thereby enabling better removal of ice from the ice surface.

[0035] refer to Figure 3 , Figure 4 and Figure 5 The snow melting device 7 includes a storage box 701, a feed inlet 702, a discharge outlet 703, and a rotating wheel 704. The storage box 701 is fixedly connected to the top of the main frame 1. The feed inlet 702 is fixedly connected to the top of the storage box 701. The discharge outlet 703 is fixedly connected to the bottom of the storage box 701 and extends through and out of the surface of the main frame 1. The rotating wheel 704 is located inside the discharge outlet 703. A drive device 13 is provided on both the left and right sides of the rotating wheel 704.

[0036] The above solution is adopted: by setting up a snow melting device 7, the snow melting agent can be spread by control after storage, thereby melting the ice on the snow removal roller brush 2 and preventing it from affecting the clearing of snow on the road after freezing.

[0037] refer to Figure 5The drive unit 13 is fixedly connected to the left and right sides of the top of the main frame 1. The drive unit 13 includes a power box 1301, a motor 1302, a drive wheel 1303, a transmission wheel 1304, a driven wheel 1305, and two transmission belts 1306. The power box 1301 is fixedly connected to the top of the main frame 1. The motor 1302 is fixedly connected to the inside of the power box 1301. The drive wheel 1303 is fixedly connected to the output end of the motor 1302. The transmission wheel 1304 is rotatably connected to the surface of the storage box 701, and the drive wheel 1303 and the transmission wheel 1304 are on the same plane. The driven wheel 1305 is rotatably connected to the surface of the discharge port 703, and the transmission wheel 1304 and the driven wheel 1305 are on the same plane. The two transmission belts 1306 are respectively sleeved on the surfaces of the drive wheel 1303 and the driven wheel 1305, as well as the surfaces of the transmission wheel 1304 and the driven wheel 1305. The driven wheel 1305 is fixedly connected to the surface of the rotating wheel 704.

[0038] By adopting the above scheme, by setting up the driving device 13, the de-icing agent stored in the snow melting device 7 can be spread, thereby achieving the purpose of de-icing.

[0039] refer to Figure 1 The bottom of the main frame 1 is fixedly connected to the first ice-breaking plate 14 by bolts. The bottom of the first ice-breaking plate 14 has three extension columns 15, which are two long and one short.

[0040] The above solution is adopted: by setting the first ice-breaking plate 14, it can come into contact with the snow removal roller brush 2 when it rotates, so that the ice that has formed on the snow removal roller brush 2 will break after being impacted.

[0041] refer to Figure 1 The bottom of the main frame 1 is fixedly connected to the second ice-breaking plate 16 by bolts. The bottom of the second ice-breaking plate 16 has three extending columns 15, and their lengths gradually decrease.

[0042] The above solution allows for the further breaking of ice clumps on the snow removal roller brush 2 by setting a second ice-breaking plate 16, thus preventing ice from remaining on its surface.

[0043] refer to Figures 1 to 7 The usage method includes the following steps: Step 1: Install the main frame 1 to the snowplow, and then add de-icing agent to the storage tank 701 through the feed inlet 702; Step 2: The snowplow starts and sweeps the snow off the ground with the snow removal roller brush 2 under the main frame 1. Then, the lifting mechanism 11 is moved by the adjusting device 8 to adjust the position of the ice removal device 5. Step 3: After the position of the ice-removing device 5 is adjusted, the ice remaining on the road surface swept by the snow removal roller brush 2 can be removed. Step 4: When the snow removal roller brush 2 begins to freeze due to the low temperature, the drive device 13 can be activated, which will then drive the snow melting device 7 to spray the snow melting agent stored in it onto the snow removal roller brush 2, thereby melting the frozen snow removal roller brush 2. The sprayed snow melting agent will fall to the ground to prevent the ground from freezing. Step 5: When the snow removal roller brush 2 rotates, it will come into contact with the first ice-breaking plate 14 and the second ice-breaking plate 16, thereby breaking the snow or ice on the snow removal roller brush 2 and preventing the snow removal roller brush 2 from being frozen.

[0044] In use, the main frame 1 is installed with the snowplow, and then de-icing agent is added to the storage tank 701 through the feed inlet 702. The snowplow is then started. As the snowplow moves, the snowplow can sweep the snow on the road surface using the snowplow brush 2. When ice forms under the snow, the electric cylinder 803 can be activated. The electric cylinder 803 drives the pressing rod 1106 to move downward. When the pressing rod 1106 moves, it drives the two connecting rods 1105 and the two pairs of push columns 1104 to move downward. When the push columns 1104 move, they squeeze the inner wall of the inclined groove 12, thereby driving the two transmission blocks 1102 to move closer to each other. When the transmission blocks 1102 move, they squeeze the second compression spring 1101 and drive the insert plate 1103 into the cavity 10. At this time, the electric cylinder 803 continues to press the fixed block 802 downward. When adjusted to the appropriate position, the electric cylinder 803 retracts, and then drives the insert plate 1103 to insert into the groove 9 on the surface of the limit block 801, thereby adjusting the position of the fixing block 802, and then fixing the position of the shovel 503. The shovel 503 can then remove the ice on the road surface. When the snow removal roller brush 2 starts to freeze, the motor 1302 can be started. The motor 1302 drives the drive wheel 1303 to rotate. After the drive wheel 1303 rotates, it drives the transmission wheel 1304 to rotate through the transmission belt 1306. Then, when the transmission wheel 1304 rotates, it drives the driven wheel 1305 to rotate through the transmission belt 1306. When the driven wheel 1305 rotates, it drives the rotating wheel 704 to rotate. In this way, the de-icing agent in the storage box 701 can be sprayed out through the rotating wheel 704, so that the de-icing agent can melt the ice on the snow removal roller brush 2.

[0045] In summary, this road snowplow and snow removal vehicle's snow removal roller brush and its usage method are described by the following components: main frame 1, snow removal roller brush 2, connecting column 3, stroke hole 4, ice removal device 5, pressure rod 501, first pressure spring 502, slanted shovel 503, baffle plate 6, snow melting device 7, storage box 701, inlet 702, outlet 703, rotating wheel 704, adjusting device 8, limit block 801, fixing block 802, electric cylinder 803, mounting plate 804, groove 9, cavity 10, lifting mechanism 11, second pressure spring 1101, transmission block 1102, and insert plate 1103. The coordinated use of the push column 1104, connecting rod 1105, pressing rod 1106, inclined groove 12, drive device 13, power box 1301, motor 1302, drive wheel 1303, transmission wheel 1304, driven wheel 1305, transmission belt 1306, first ice-breaking plate 14, extension column 15 and second ice-breaking plate 16 solves the problem that when the snow removal roller brush is clearing snow from the road, ice will gradually form on its surface, increasing the weight and resistance of the snow removal roller brush, making it difficult to push and rotate, thus affecting the problem of clearing snow from the road.
