Description

Technical Field

[0001] This utility model belongs to the field of snow removal equipment technology, specifically relating to a new type of automatic force-driven snow sweeper. Background Technology

[0002] Most existing snow removal equipment relies on the snowplow's own power for brush drive or employs a non-powered design, resulting in insufficient power and low snow removal efficiency, especially on thick snow or icy surfaces. Furthermore, traditional snowplow brushes often use chain gears or synchronous belts for transmission, which are prone to wear and breakage due to snow impact, leading to frequent and costly maintenance. In addition, existing snowplow brushes suffer from insufficient structural strength, easily deforming under long-term loads; brush roller disassembly requires complex operations, hindering maintenance convenience; and the adjustment mechanism has limited flexibility, making it difficult to adapt to snow removal needs at different road angles and heights, thus restricting the adaptability and stability of snow removal operations.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Please refer to Figure 1-5As shown, an embodiment of this application provides a novel automatic force-driven snow brush, including a brush disc drive device 5, brush disc assemblies 4, brush rollers 54, and a snow sweeping cover 2. Multiple brush disc assemblies 4 are equidistantly fixedly mounted on the surface of the brush rollers 54 along the axial direction. The drive device includes an engine 51, with a commutator 53 fixedly mounted vertically at the bottom of the engine 51. The output shaft of the engine 51 is fixedly mounted to the input end of the commutator 53 via a coupling. A drive shaft 56 is provided at the output end of the bottom of the commutator 53. The brush rollers 54 are arranged in a straight line. Two brush rollers 54 are respectively connected to the two ends of the drive shaft 56. The end of the brush roller 54 away from the commutator 53 is rotatably connected to the bottom of the support arm 52. The snow sweeper hood 2 is fixedly installed between the tops of the two support arms 52. The top of the commutator 53 and the bottom of the engine 51 are both fixedly installed on the top of the snow sweeper hood 2. The engine hood 1 is provided on the outer cover of the engine 51. The engine hood 1 is fixedly installed with the snow sweeper hood 2. A rotating adjustment frame 3 is provided in the center of the back of the snow sweeper hood 2. The rotating adjustment frame 3 is fixedly installed with the snow sweeper.

[0018] Specifically, such as Figure 1-2 As shown, this snow sweeper is driven by its own engine 51. The torque output from the vertical output shaft of the engine 51 is converted into horizontal torque by the commutator 53. The commutator 53 is provided with two synchronously rotating output ends, thereby synchronously driving the two brush rollers 54 to rotate synchronously. Since the power source is independent, this snow sweeper has strong power, thus significantly improving its snow sweeping ability compared to snow sweeper rollers that are driven by the snow sweeper engine 51 or have no power drive. Secondly, since a rigid and robust transmission connection method such as a commutator 53 is chosen between the engine 51 and the brush roller 54, the probability of maintenance and damage is greatly reduced compared to the transmission methods of chain gear transmission or synchronous pulley belt transmission, and it is also superior in terms of power transmission.

[0019] In a preferred embodiment of the present invention, the support arm 52 is further described as a box-type structure, and a bearing seat 521 is fixedly installed at the bottom of one side of the inner wall of the support arm 52. The inner ring of the bearing seat 521 is fixedly connected to one end of the driven shaft 522.

[0020] In a preferred embodiment of the present invention, bushings 55 are fitted inside both ends of the brush roller 54. The bushings 55 are fixedly installed to the brush roller 54 by bolt assembly. An insertion hole 551 is provided in the middle of one end face of the bushing 55. The drive shaft 56 and the driven shaft 522 are both hexagonal shafts and match the shape of the insertion hole 551.

[0021] In a preferred embodiment of the present invention, a snap-on lifting caster 523 is further fixedly installed on the front of the support arm 52 along the vertical direction.

[0022] Specifically, such as Figure 2 As shown, to facilitate quick disassembly, maintenance, or replacement of the brush roller 54, bushings 55 are inserted into both ends of the hollow brush roller 54. The bushings 55 can slide and adjust their position within the brush roller 54, and are then connected and fixed by fasteners such as bolt assemblies and pins. At the same time, insertion holes 551 are opened in the middle of the bushings 55 to match the shape of the drive shaft 56 and the transmission shaft. Since the distance between the drive shaft 56 and the driven shaft 522 is fixed, the length of the two bushings 55 extending out of the brush roller 54 is adjustable. With the help of hexagonal connecting holes and the shape of the shaft body, they can be inserted. Therefore, the drive shaft 56 and the driven shaft 522 do not need to be fastened to the bushings 55. Thus, when disassembling the brush roller 54, only the bushings 55 need to be unlocked and the position adjusted to complete the disassembly of the brush roller 54, which is very convenient and quick. On the other hand, by setting a snap-on lifting caster 523 at the front end of the support arm 52, it is in a retracted state under normal conditions and will not affect the normal operation of the snow sweeper. When maintenance is required, its length can be adjusted to make it fall to the ground, thereby supporting the snow sweeper cover 2 and preventing it from collapsing and injuring people.

[0023] In a preferred embodiment of the present invention, the snow sweeper 2 further includes a cover body 21, a snow baffle 26 is fixedly installed at the front end of the cover body 21, a plurality of reinforcing ribs 24 are fixedly installed at intervals along the length of the top surface of the snow sweeper 2, a load-bearing beam 23 is fixedly installed between the two reinforcing ribs 24 in the middle, a connecting plate 22 is fixedly installed at the top center of the cover body 21, the top end of the commutator 53 is fixedly installed with the connecting plate 22, and the bottom of the engine 51 is fixedly installed on the top of the load-bearing beam 23.

[0024] In a preferred embodiment of this utility model, the left and right sides of the load-bearing beam frame 23 are further fixedly installed with crank-type lifting casters 25 in the vertical direction.

[0025] Specifically, such as Figure 3 As shown, since the incremental engine 51 serves as an automatic power source, the snow sweeper needs to be reinforced. The strength of the overall frame is increased by setting multiple vertical reinforcing ribs 24 at intervals on the top surface of the cover 21, and its load-bearing capacity is further improved by setting a load-bearing beam 23 in the middle. This allows the snow sweeper cover 2 to bear the weight of the engine 51 and cope with harsh working environments. At the same time, the stability of the snow sweeper cover 2 is further increased by setting crank-type lifting casters 25 on the back of the snow sweeper cover 2 near both ends, which facilitates daily operation and maintenance.

[0026] In a preferred embodiment of this utility model, the rotating adjustment frame 3 further includes a telescopic frame 32, the telescopic frame 32 includes a fixed frame 321, the fixed frame 321 is fixedly installed with the snow sweeper, the top and bottom center of the front of the fixed frame 321 are respectively vertically hinged to one end of two connecting frames 322, the other end of the two connecting frames 322 are respectively vertically hinged to the top and bottom of the back of the parallel frame 323, and the front of the parallel frame 323 is horizontally hinged to the back of the load-bearing beam frame 23.

[0027] In a preferred embodiment of this utility model, the left and right sides of the parallel frame 323 are respectively hinged to the cylinder bodies of two horizontal drive hydraulic cylinders 31, the telescopic shaft ends of the horizontal drive hydraulic cylinders 31 are hinged to the back of the load-bearing beam frame 23, the bottom of the front of the fixed frame 321 is hinged to the cylinder body of the vertical drive hydraulic cylinder 33, and the telescopic shaft of the vertical drive hydraulic cylinder 33 is connected to the bottom of the upper connecting frame 322.

[0028] Specifically, such as Figure 5 As shown, a parallelogram linkage mechanism consisting of a fixed frame 321, two connecting frames 322, and a parallel frame 323 enables the parallel frame 323 to move up and down parallel to the fixed frame 321. With the driving force of the vertical drive hydraulic cylinder 33, the up and down adjustment position of the snow sweeper 2 is controlled. The snow sweeper 2 is hinged to the parallel frame 323 in the horizontal direction, and with the drive of the horizontal drive hydraulic cylinder 31, it swings left and right to adjust the angle of its horizontal swing head. The hydraulic pump station is installed on the fixed frame 321 and driven by the engine 51, achieving complete independence from the snow sweeper and realizing self-drive.

[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
