Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] As described in the background section, a snow removal roller brush is a mechanical device specifically designed for clearing snow from roads. However, existing snow removal roller brushes suffer from limited installation space and inconvenient installation, resulting in low stability of snow removal work and affecting the snow removal effect.

[0043] Based on this, please refer to Figures 1-6 The present invention provides a snow removal roller brush 100 and a snow removal vehicle 1000, which can effectively improve the aforementioned technical problems. Specifically, they are easy to install, can make full use of installation space, and improve the stability and effectiveness of snow removal work. The snow removal roller brush 100 and the snow removal vehicle 1000 will be described in detail below.

[0044] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of the snowplow 1000 provided in this embodiment, combined with... Figure 1 The snowplow 1000 includes a frame 200 and a snowplow brush 100. The snowplow brush 100 is mounted on the frame 200 and is used to clear snow from the road surface.

[0045] As will be readily apparent to those skilled in the art, the snowplow 1000 also includes other structures such as the vehicle body and wheels, which will not be described in detail in this embodiment.

[0046] Please refer to Figure 2 , Figure 2 This is a partial structural diagram of the snow removal roller brush 100 provided in this embodiment, combined with... Figure 1 and Figure 2The snow removal roller brush 100 includes a roller brush device 30, a lifting drive device 20, and at least two linkage mechanisms 10. The roller brush device 30 is used to rotate and clean the snow on the ground. The at least two linkage mechanisms 10 are spaced apart at both ends of the roller brush device 30. The lifting drive device 20 is connected to one end of the at least two linkage mechanisms 10. The at least two linkage mechanisms 10 are used to drive the roller brush device 30 to move up and down under the drive of the lifting drive device 20.

[0047] In other words, by setting at least two linkage mechanisms 10 on the roller brush device 30, the linkage mechanisms 10 can be conveniently installed at different positions on the frame 200 according to the arrangement of other components on the frame 200, thereby making full use of the installation space of the frame 200 and avoiding restrictions on the installation of the snow removal roller brush 100. Furthermore, under the driving action of the lifting drive device 20, at least two linkage mechanisms 10 can be driven to move simultaneously, realizing the overall lifting movement of the roller brush device 30. This method of setting at least two linkage mechanisms 10 on the roller brush device 30 makes the snow removal operation highly stable, thereby improving the snow removal effect.

[0048] Specifically, at least one linkage mechanism 10 is provided on each of the opposite sides of the frame 200, and the lifting drive device 20 is disposed on the frame 200. It should be noted that in this embodiment, there are two linkage mechanisms 10, each disposed on an opposite side of the frame 200. This saves installation space in the middle of the rear of the frame 200, facilitating the installation of other components in the middle position. Of course, in other embodiments, the number of linkage mechanisms 10 can be three or four, etc.; for example, when there are three, one linkage mechanism 10 is provided on one side of the frame 200, and two linkage mechanisms 10 are provided on the other side. In other words, the number of linkage mechanisms 10 and their specific positions on the frame 200 need to be determined according to the actual design requirements.

[0049] To further maximize the use of installation space, at least two linkage mechanisms 10 are located at the rear of the frame 200. In other words, the snow removal roller brush 100 is rear-mounted, positioned at the rear of the frame 200, which can be understood as being behind the rear wheels of the snowplow 1000. This saves installation space at the front or middle of the frame 200, allowing the snowplow 1000 to accommodate other snow removal devices or equipment at the front or middle, enabling them to work in conjunction with the snow removal roller brush 100. This achieves multi-purpose functionality, increases operational capacity, and further improves snow removal efficiency.

[0050] Please refer to Figure 3 , Figure 3 This is an assembly diagram of the linkage mechanism 10 and the lifting drive device 20 provided in this embodiment, combined with... Figures 1-3At least one of the two linkage mechanisms 10 is a parallelogram mechanism. By setting a parallelogram mechanism, the roller brush device 30 can be raised and lowered smoothly, thereby improving its operational stability and ensuring the snow removal effect.

[0051] Specifically, in this embodiment, the parallelogram mechanism includes a mounting base 11, a first connecting rod 12, a second connecting rod 13, and a swing frame 14. The two ends of the first connecting rod 12 are respectively hinged to the mounting base 11 and the swing frame 14, and the two ends of the second connecting rod 13 are respectively hinged to the mounting base 11 and the swing frame 14. The first connecting rod 12 and the second connecting rod 13 are arranged in parallel. One end of the swing frame 14 is connected to the roller brush device 30, and the lifting drive device 20 is connected to the swing frame 14.

[0052] Please refer to Figure 4 , Figure 4 This is an assembly diagram of the linkage mechanism 10 and the frame 200 provided in this embodiment, combined with... Figures 2-4 To further improve the stability of the roller brush device 30 during lifting and lowering, the swing frame 14 is provided with a guide groove 141. The snow removal roller brush 100 also includes at least two guide wheel assemblies 40, each corresponding to at least two linkage mechanisms 10. The guide wheel assemblies 40 are used to connect to the frame 200 of the snow removal vehicle 1000 (specifically, to the external frame on the frame 200). Each guide wheel assembly 40 includes a guide wheel 41, which is fitted into the guide groove 141. Specifically, during installation, the guide wheel 41 is fixedly connected to the frame 200. When the lifting drive device 20 drives the swing frame 14 to move, the swing frame 14 can move relative to the guide wheel 41. In other words, during lifting and lowering, the guide wheel 41 always slides within the guide groove 141. This arrangement improves the lateral connection rigidity of the swing frame 14, reduces its lateral swaying during movement, and further improves the motion stability of the linkage mechanism 10, ensuring smooth lifting and lowering of the roller brush device 30.

[0053] Furthermore, to improve the installation stability of the guide wheel 41 and the frame 200, the guide wheel assembly 40 also includes a fastener 42, which passes through the guide wheel 41 and is fixedly connected to the frame 200. It should be noted that the fastener 42 in this embodiment is a pin bolt, which is located on the side of the frame 200, passes through the guide wheel 41, and is locked to the side of the guide wheel 41 away from the frame 200 by a nut.

[0054] Please continue to combine Figure 4 The guide wheel assembly 40 also includes a first buffer pad 43, which is fitted onto the fastener 42 and located between the swing frame 14 and the frame 200. By providing the first buffer pad 43, the stiffness of the swing frame 14 in the left-right direction can be increased, ensuring the stability of the structure.

[0055] Specifically in this embodiment, the guide wheel 41 is a stepped bushing with a flange surface, the flange surface of which is connected to the first buffer pad 43. The first buffer pad 43 is fitted onto the fastener 42 and cooperates with the stepped bushing. When the swing frame 14 moves up and down, the guide wheel 41 can rotate around the fastener 42, thereby ensuring the smoothness of the movement process.

[0056] Please continue to combine Figure 1 Specifically, the lifting drive device 20 includes a fixed frame 21 and at least two lifting hydraulic cylinders 22. The at least two lifting hydraulic cylinders 22 are spaced apart from each other on the fixed frame 21, and each of the at least two lifting hydraulic cylinders 22 is connected to at least two linkage mechanisms 10. In this embodiment, the lifting hydraulic cylinders 22 are connected to the swing frame 14, and the fixed frame 21 is mounted on the frame 200. By corresponding the at least two lifting hydraulic cylinders 22 to the at least two linkage mechanisms 10 one-to-one, the lifting drive device 20 can be easily installed, and the movement of the linkage mechanisms 10 can be easily controlled. In addition, when a component malfunctions, it is also convenient to repair or replace the lifting hydraulic cylinders 22 or the linkage mechanisms 10, or other structures.

[0057] It should be noted that in this embodiment, there are two lifting hydraulic cylinders 22, each connected to one of the two linkage mechanisms 10. Of course, in other embodiments, the number may be three or four, etc., depending on the actual design.

[0058] Furthermore, in order to achieve synchronous control of the lifting hydraulic cylinders 22, the lifting drive device 20 also includes a hydraulic synchronization valve 23, which is connected to at least two lifting hydraulic cylinders 22 at the same time, thereby ensuring the synchronous movement of multiple lifting hydraulic cylinders 22 and improving the lifting stability of the swing frame 14 and the roller brush device 30.

[0059] Combination Figure 1 and Figure 2 In this embodiment, the roller brush device 30 includes a brush roller 31, a roller brush frame 32, and two drive mechanisms 33. The roller brush frame 32 is connected to two linkage mechanisms 10, and the brush roller 31 is connected to both ends of the roller brush frame 32. The two drive mechanisms 33 are respectively disposed at both ends of the roller brush frame 32, and both drive mechanisms 33 are connected to the brush roller 31. That is, the lifting drive device 20 drives the brush roller 31 to rise and fall through the linkage mechanism 10 and the roller brush frame 32, so that the brush roller 31 contacts the ground, and then operates the drive mechanism 33 to drive the brush roller 31 to rotate, so as to remove the snow on the ground.

[0060] It should be noted that the roller brush frame 32 and the brush roller 31 are at a fixed angle to the direction of travel of the snowplow 1000, and there is no sway cylinder setting, which makes snow removal operation more convenient.

[0061] Combination Figure 2 Specifically, the drive mechanism 33 includes a hydraulic motor 331 and a transmission component 332. The hydraulic motor 331 is located on the side of the roller brush frame 32 away from the brush roller 31, and the transmission component 332 is located on the roller brush frame 32 and is connected to both the hydraulic motor 331 and the brush roller 31.

[0062] It should be noted that in this embodiment, the two transmission components 332 are respectively connected to the two ends of the brush roller 31, and the brush roller 31 is provided with plastic filaments in the axial direction. The brush roller 31 is driven to rotate at high speed by the hydraulic motor 331 to sweep the snow to the outside of the vehicle, thereby achieving efficient snow removal.

[0063] Combination Figure 1 and Figure 2 The hydraulic motor 331 can be understood as being positioned above the roller brush frame 32 and close to the swing frame 14, that is, positioned inward, so as to avoid the snowplow 1000 being damaged by impacts from the external environment during operation.

[0064] It should be noted that in this embodiment, the transmission component 332 is specifically a sprocket and chain transmission structure. Of course, in other embodiments, the transmission component 332 can also be a belt pulley transmission structure or a gear transmission structure, etc.

[0065] Furthermore, the drive mechanism 33 also includes a pressure sensor (not shown in the figure). The pressure sensor is located in the oil circuit of the hydraulic motor 331. When the brush roller 31 is overloaded and reaches the overflow pressure, an alarm can be triggered through the control box in the cab to remind the driver to pay attention and adjust the operation of the snow removal roller brush 100 to avoid damage to it.

[0066] Please continue to combine Figure 1 and Figure 2 The roller brush device 30 also includes two lifting wheels 34, which are respectively disposed at both ends of the roller brush frame 32. By setting the lifting wheels 34, the brush roller 31 can be supported. When the bristles of the brush roller 31 are worn, the height of the lifting wheels 34 can be adjusted so that the bristles of the brush roller 31 are always in contact with the ground, thereby improving the snow removal efficiency.

[0067] For details, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the lifting and traveling wheel 34 provided in this embodiment. Figure 6 This is a cross-sectional view of the lifting travel wheel 34 provided in this embodiment, combined with... Figure 5 and Figure 6The lifting travel wheel 34 includes a travel wheel 341, axle 342, inner tube support 343, outer tube support 344, lead screw 345, and crank handle 347. The travel wheel 341 is mounted on the axle 342, and the axle 342 is connected to the inner tube support 343. The outer tube support 344 is sleeved on the inner tube support 343. The lead screw 345 is mounted inside the outer tube support 344 and is connected to the inner tube support 343. The crank handle 347 is mounted on the outer tube support 344 and is connected to the lead screw 345.

[0068] It is easy to understand that by operating the crank 347 to rotate the lead screw 345, the inner tube support 343 moves up and down within the outer tube support 344, thereby adjusting the height of the traveling wheel 341.

[0069] Furthermore, in order to improve the rotational stability of the lead screw 345 and to protect the lead screw 345 and the inner tube support 343, the lifting travel wheel 34 also includes a second buffer pad 346. The second buffer pad 346 is disposed inside the outer tube support 344 and is located between the top of the outer tube support 344 and the flange plate of the lead screw 345.

[0070] In addition, in order to limit the crank handle 347, the lifting travel wheel 34 also includes a limiting plate 348, which is disposed on the outer tube support 344 and is used to abut against the crank handle 347.

[0071] In summary, the embodiments of this utility model provide a snow removal roller brush 100 and a snow removal vehicle 1000. The snow removal roller brush 100 includes a roller brush device 30, a lifting drive device 20, and at least two linkage mechanisms 10. The roller brush device 30 is used to rotate and clean the snow on the ground. The at least two linkage mechanisms 10 are spaced apart at both ends of the roller brush device 30. The lifting drive device 20 is connected to one end of the at least two linkage mechanisms 10. The at least two linkage mechanisms 10 are used to drive the roller brush device 30 to move up and down under the drive of the lifting drive device 20. In other words, by setting at least two linkage mechanisms 10 on the roller brush device 30, the linkage mechanisms 10 can be conveniently installed at different positions on the frame 200 according to the arrangement of other components on the frame 200, thereby making full use of the installation space of the frame 200 and avoiding restrictions on the installation of the snow removal roller brush 100. Furthermore, under the driving action of the lifting drive device 20, at least two linkage mechanisms 10 can be driven to move simultaneously, realizing the overall lifting movement of the roller brush device 30. This method of setting at least two linkage mechanisms 10 on the roller brush device 30 makes the snow removal operation highly stable, thereby improving the snow removal effect.

[0072] The snowplow 1000 includes a snowplow brush 100, which has all the functions and benefits of the snowplow brush 100.

[0073] The above description is merely a specific embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
