Description

Technical Field

[0001] This utility model relates to a snow removal device, specifically a snow removal roller brush and a road snow removal vehicle using this snow removal roller brush, belonging to the field of sanitation machinery and equipment technology. Background Technology

[0002] Currently available snowplows with roller brushes work by using rolling brushes to sweep up snow from the road surface and then throwing the swept snow outwards in the direction of the brushes' rotation, thus accumulating it on the side of the road. However, on wide roads with multiple lanes, these snowplows often don't throw enough snow off the road, leaving it to accumulate in adjacent lanes. Subsequent snow removal of adjacent lanes is hampered by the excessive snow accumulation, hindering the snowplow's normal operation. Therefore, for multi-lane roads, these snowplows often only clear one lane for vehicles, impacting traffic efficiency.

[0003] To address this issue, the applicant has developed a novel snow-sweeping roller brush and a road snowplow using this brush. The roller brush picks up snow from the road and feeds it into a vehicle-mounted conveyor channel, which then transports the snow to a cargo box located above and behind the vehicle. When using this snowplow to clear snow from multi-lane roads, the snow does not accumulate in adjacent lanes, allowing for convenient clearing of multiple lanes one by one, thus freeing up multiple lanes for traffic and improving traffic efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a snow sweeping roller brush and a road snow sweeper that uses this snow sweeping roller brush, so as to solve the problem that existing roller brush snow sweepers are not convenient to sweep multiple lanes for vehicles to pass when sweeping snow on multi-lane roads.

[0005] The specific technical solution of this utility model is as follows:

[0006] A snow sweeping roller brush has a roller brush body, which is assembled from three main components: a support frame, a chain-type roller brush, and an inclined support plate.

[0007] The support frame is supported by a set of horizontal and longitudinal sprocket shafts mounted on bearings. Each sprocket shaft has a brush sprocket fixedly connected to its front and rear ends. The two sets of brush sprockets at the front and rear ends jointly support the chain-type rolling brush. The support frame contains a brush drive motor, which drives all sprocket shafts and brush sprockets to rotate synchronously via a chain transmission mechanism. The support frame has two adjustable support feet on each of its front and rear sides, with universal support wheels at the bottom. The four feet provide support for the height of the support frame. The lower part of the support frame has a horizontal L-shaped bracket on each of its front and rear sides, with the two L-shaped brackets facing each other.

[0008] The chain-type rolling brush has two vertical chain rings, one at the front and one at the back. These two chain rings encircle the two sets of roller brush sprockets at the front and rear ends, respectively, and mesh with each other. The lower section of each vertical chain ring is a horizontal chain segment, with one side of the horizontal chain segment connected to an upward-sloping chain segment. A set of brush modules, evenly spaced along the outer edge of each vertical chain ring, spans between the two vertical chain rings. Driven by the roller brush drive motor, the two vertical chain rings rotate in the direction from the horizontal chain segment to the inclined chain segment, and each brush module moves synchronously with the vertical chain rings. Each brush module has a strip-shaped base plate. A snow-sweeping strip brush with bristles extending outward from the vertical chain ring is fixedly installed in the middle of the base plate. Guide wheel brackets are installed at both ends of the base plate, and horizontal guide wheels and vertical guide wheels are mounted on the guide wheel brackets. When the brushing module follows the vertical chain ring to the horizontal chain section at the lower part of the vertical chain ring, the horizontal guide wheels and vertical guide wheels on the guide wheel brackets at both ends of the brushing module roll against the two inner sides of the L-shaped brackets on the front and rear sides. The two L-shaped brackets limit and support the brushing module, so that the brushing module maintains the same distance when it travels to the horizontal chain section of the vertical chain ring to brush the ground.

[0009] The inclined support plate is fixedly connected to the support frame and is erected parallel to the outside of the inclined chain section of the vertical chain ring of the chain-type rolling brush. The inclined support plate has baffles on both sides and a wear-resistant rubber plate at the lower end of the inclined support plate as the end to rest against the ground. When the brushing module moves to the inclined chain section of the vertical chain ring, it maintains the same distance to brush the inclined support plate. The upper edge of the inclined support plate is the discharge port.

[0010] Furthermore, the snow sweeping brush is equipped with a horizontally installed hanger above the brush body. The hanger suspends the brush body via a rope wound around a pulley assembly. The pulley assembly has corresponding pulleys on both the hanger and the support frame of the brush body. A winch on the hanger controls the raising and lowering of the rope. The front and rear ends of the hanger are respectively equipped with double-row roller chains that can bend up and down but cannot swing back and forth, connecting to the front and rear sides of the support frame of the brush body to limit the back and forth swing of the brush body.

[0011] A road snowplow using the aforementioned snow-sweeping roller brush has a tipping unloading compartment located behind the cab. Two parallel, non-interfering snow-sweeping roller brushes are mounted on the lower front of the cab. The hangers of the two roller brushes are fixedly connected to the front end of the front crossbeam of the frame. The main bodies of the two roller brushes are symmetrically arranged with their inclined support plates located on the outer sides. The chain-type roller brush of the left roller brush rotates clockwise when viewed from front to back, while the chain-type roller brush of the right roller brush rotates counterclockwise when viewed from front to back. Material conveying channels extending from the outer side of the discharge port of the inclined support plate of the corresponding snow-sweeping roller brush to the top of the compartment are also provided on the left and right sides of the vehicle body.

[0012] When the two snow-sweeping rollers of this road snowplow sweep the snow to the left and right sides of the ground respectively, there is a blind spot between the two roller brush bodies, where snow accumulates. To solve this problem, a belt roller brush supported by a front bracket is installed at the front end of the gap between the two roller brush bodies. The belt roller brush has a wide conveyor belt ring supported by two rollers on the left and right sides. The lower section of the conveyor belt ring is a horizontal conveyor belt section. Snow-sweeping brushes are installed at the center front and back of the outer edge of the conveyor belt ring. The front bracket is fixedly connected to the support frame of the left roller brush body, and the left roller extends forward from the sprocket shaft at the rightmost end of the left roller brush body to serve as the drive shaft. The belt-type rolling brush rotates in the same direction as the chain-type rolling brush of the left rolling brush body. When the snow-sweeping brush follows the belt ring to the horizontal conveyor belt section, it can sweep the ground. The front support also has two longitudinally extending guide wheels with anti-reverse flanges at the rear of the lower section of the corresponding conveyor belt ring. The two anti-reverse guide wheels are staggered left and right, and their surfaces press against the upper and lower surfaces of the lower section of the conveyor belt ring respectively. A gap is left between the front end of the lower anti-reverse guide wheel and the snow-sweeping brush to avoid motion interference. The anti-reverse flanges of the two guide wheels press against the rear edge of the conveyor belt ring, thus preventing the conveyor belt ring from rolling backward and causing operational failure when following the snowplow. The belt-type rolling brush can first sweep the snow in the cleaning dead corner between the two rolling brush bodies to one side, and then the rolling brush body on that side can clean it, thus avoiding the accumulation of snow in the cleaning dead corner between the two rolling brush bodies.

[0013] When this snow-sweeping roller brush is in operation, the brushing module of the chain-type roller brush travels to the horizontal chain section below the vertical chain ring, where it brushes the snow on the ground towards the inclined plate and feeds it into the lower end of the inclined plate. Then, the brushing module, traveling to the inclined chain section of the vertical chain ring, sends the snow from the lower end of the inclined plate upwards along the inclined plate to the upper edge of the inclined plate for output. Road snowplows using this snow-sweeping roller brush are equipped with two parallel snow-sweeping roller brushes at the front and material conveying channels on both sides of the vehicle body. The snow output by the snow-sweeping roller brush is transported through the material conveying channels to the truck bed for storage until the truck bed is full, and then transported to a designated location for unloading. Therefore, when road snowplows using this snow-sweeping roller brush clear snow from multi-lane roads, the swept snow will not accumulate on adjacent lanes, allowing for convenient clearing of multiple lanes one by one, thus clearing multiple lanes for vehicles to pass and improving traffic efficiency.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings. In the description of the present invention, the directional terms "front," "rear," "left," "right," "up," and "down" are based on the accompanying drawings. Figure 1 and Figure 9 The orientation or positional relationship shown is defined only for the convenience of describing this utility model, and does not refer to a specific orientation that the device or component must have, and should not be regarded as a limitation of this utility model.

[0031] like Figures 1-8 As shown, this snow sweeping roller brush has a roller brush body, which is assembled from three main components: a support frame 1, a chain roller brush 2, and an inclined support plate 3.

[0032] The support frame 1 is supported by a set of horizontal longitudinal sprocket shafts 4 via bearings. Each sprocket shaft 4 has a roller brush sprocket 5 fixedly connected to its front and rear ends. The two sets of roller brush sprockets 5 at the front and rear ends support the chain-type roller brush 2. The support frame 1 is equipped with a roller brush drive motor 6, which drives all the sprocket shafts 4 and roller brush sprockets 5 to rotate synchronously via a chain transmission mechanism. The support frame 1 has two adjustable support feet 7 on each of its front and rear sides, with universal support wheels at the bottom. The four support feet 7 provide support for the support frame 1. The support frame 1 has a horizontal L-shaped bracket 8 on each of its front and rear sides at the bottom. The two L-shaped brackets 8 are arranged in a front-to-back orientation.

[0033] The chain-type rolling brush 2 has two vertical chain rings 9, which are respectively wrapped around the two sets of roller brush sprockets 5 at the front and rear ends and mesh with each other. The lower section of the vertical chain ring 9 is a horizontal chain segment, and one side of the horizontal chain segment is connected to an inclined chain segment that slopes upward. A set of brush sweeping modules 10 are strung between the two vertical chain rings 9 and are evenly distributed along the outer edge of the vertical chain rings 9. Driven by the roller brush drive motor 6, the two vertical chain rings 9 rotate in the direction of travel from the horizontal chain segment to the inclined chain segment, and each brush sweeping module 10 moves synchronously with the vertical chain ring 9. The brush sweeping module 10 has a strip-shaped base plate 10.1, and a brush is fixedly installed in the middle of the base plate 10.1. The snow sweeping brush 10.2 extends outward from the vertical chain ring 9. Guide wheel brackets 10.3 are installed at both ends of the base plate 10.1. Horizontal guide wheels 10.4 and vertical guide wheels 10.5 are mounted on the guide wheel brackets. When the sweeping module 10 follows the vertical chain ring 9 to the horizontal chain section below the vertical chain ring 9, the horizontal guide wheels 10.4 and vertical guide wheels 10.5 on the guide wheel brackets 10.3 at both ends of the sweeping module 10 roll against the two inner sides of the L-shaped brackets 8 on the front and rear sides. The two L-shaped brackets 8 limit and support the sweeping module 10, so that the sweeping module 10 maintains the same distance when it travels to the horizontal chain section of the vertical chain ring 9 to sweep the ground.

[0034] The inclined support plate 3 is fixedly connected to the support frame 1 and is erected parallel to the outside of the inclined chain section of the vertical chain ring 9 of the chain-type rolling brush 2. The inclined support plate 3 has baffles on both sides and a wear-resistant rubber plate 3.1 at the lower end of the inclined support plate 3 as the end to rest against the ground. When the brushing module 10 moves to the inclined chain section of the vertical chain ring 9, it maintains the same distance to brush the inclined support plate 3. The upper edge of the inclined support plate 3 is the discharge port.

[0035] Furthermore, the snow sweeping brush is equipped with a horizontally installed hanger 11 above the brush body. The hanger 11 suspends the brush body through a rope 13 that is wound around a pulley assembly 12. The pulley assembly 12 is equipped with corresponding pulleys on both the hanger 11 and the support frame 1 of the brush body. A winch 14 is installed on the hanger 11 to control the winding and unwinding of the rope 13. The front and rear ends of the hanger 11 are respectively equipped with double-row roller chains 15 that can be bent up and down but cannot swing back and forth, which are connected to the front and rear sides of the support frame 1 of the brush body to limit the back and forth swing of the brush body.

[0036] Furthermore, tensioning sprockets 16 are respectively mounted on the upper part of the support frame 1 at the front and rear sides on the same vertical plane as the roller brush sprocket 5. The tensioning sprockets 16 engage and tension the upper section of the two vertical chain rings 9 of the chain roller brush 2 from the inside.

[0037] Furthermore, the snow sweeping strip brush 10.2 of the brush sweeping module 10 is a strip brush made of a mixture of steel wire and plastic wire.

[0038] This snow sweeping roller brush is used to sweep uncompacted snow on roads. During operation, the winch 14 controls the hoisting rope 13 to lower the main body of the roller brush. Under the action of the roller brush's own weight, the universal support wheels of the support frame 1's legs 7 pass through the snow and touch the ground. The brush sweeping module 10 of the horizontal chain section below the chain-type roller brush 2 and the lower end of the inclined support plate 3 extend into the snow. After the roller brush drive motor 6 starts, the brush sweeping module 10 of the horizontal chain section moves towards the inclined chain section, which can sweep the snow on the ground along the inclined support plate 3 and feed it into the lower end of the inclined support plate 3. Then, the brush sweeping module 10, which has moved to the inclined chain section, sends the snow at the lower end of the inclined support plate 3 upward along the inclined support plate 3 to the discharge port on the upper edge of the inclined support plate 3 for external output.

[0039] like Figures 9-15 As shown, a road snowplow using the aforementioned snow-sweeping roller brush has a tipping unloading compartment 17 located behind the cab. Two parallel snow-sweeping roller brushes, arranged independently, are mounted on the lower front of the cab. The hangers 11 of the two snow-sweeping roller brushes are fixedly connected to the front end of the front crossbeam of the frame. The main bodies of the two snow-sweeping roller brushes are arranged symmetrically, with the inclined support plates 3 located on the outer side. The chain roller brush 2 of the left roller brush rotates clockwise when viewed from front to back, and the chain roller brush 2 of the right roller brush rotates counterclockwise when viewed from front to back. Material conveying channels are also provided on the left and right sides of the vehicle body, extending from the outer side of the discharge port of the inclined support plate 3 of the corresponding snow-sweeping roller brush to the top of the compartment 17.

[0040] Furthermore, the material conveying channel is provided with a primary spiral conveying pipe 18 extending from the outside of the discharge port of the snow sweeper roller brush inclined support plate 3 towards the lower part of the middle of the carriage 17 and a secondary spiral conveying pipe 19 extending from the lower part of the middle of the carriage 17 towards the upper part of the middle of the carriage 17. The inlet at the front end of the primary spiral conveying pipe 18 forms a material receiving port with the discharge port of the snow sweeper roller brush inclined support plate 3. The discharge port at the rear end of the primary spiral conveying pipe 18 is connected to the inlet at the lower end of the secondary spiral conveying pipe 19 via an intermediate pipe joint 20. The discharge port at the upper end of the secondary spiral conveying pipe 19 is connected to a discharge pipe 21 for discharging material into the carriage 17.

[0041] Furthermore, the front end of the primary spiral conveying pipe 18 is fixedly connected to the support frame 1 of the snow sweeping roller brush on the same side. The rear end of the primary spiral conveying pipe 18 is supported on the frame by a universal support 22. The intermediate pipe joint 20 between the primary spiral conveying pipe 18 and the secondary spiral conveying pipe 19 adopts a retractable and torsionable corrugated pipe joint. The universal support 22 is provided with a clamp 22.1 to hold the pipe body of the primary spiral conveying pipe 18 tightly. A downwardly extending vertical shaft 22.2 is fixedly connected below the clamp 22.1. A transverse rotating shaft 22.4 is mounted on the frame below the clamp 22.1 by a pair of roller bearings 22.3. The middle part of the transverse rotating shaft 22.4 is cross-connected with the vertical shaft 22.2 below the clamp 22.1 by a fisheye spherical bearing 22.5. With the above design, when the snow sweeping roller brush sways due to uneven ground during snow sweeping operations, the primary spiral conveying pipe 18 can follow the snow sweeping roller brush to a certain extent.

[0042] Furthermore, the discharge pipe 21 is provided with a pipe seat 21.1 fixedly connected to the discharge port of the secondary spiral conveying pipe 19. A rotatable pipe head 21.2 is connected to the pipe seat 21.1. The pipe body of the rotatable pipe head 21.2 is formed by bending and connecting a connecting section pipe body and a pipe mouth section pipe body. The port of the connecting section pipe body is rotatably snapped onto the pipe seat 21.1 through an annular groove. A large gear 21.3 is fixedly fitted around the connecting section pipe body. A small gear 21.5 that meshes with the large gear 21.3 and is driven by a control motor 21.4 is installed around the pipe seat 21.1. The control motor 21.4 controls the orientation of the pipe mouth section pipe body of the rotatable pipe head 21.2. When the rotatable pipe head 21.2 discharges material into the carriage 17, the control motor 21.4 controls the pipe opening section of the rotatable pipe head 21.2 to face the inside of the carriage 17; when the carriage 17 is tipping over to unload material, the control motor 21.4 controls the pipe opening section of the rotatable pipe head 21.2 to face the outside of the carriage 17, so as to avoid positional interference between the rotatable pipe head 21.2 and the carriage 17 tipping over to unload material.

[0043] When the two snow sweeping brushes of this road snowplow sweep the ground to the left and right, there is a blind spot between the two brush bodies, where snow accumulates. To solve this problem, a belt-type brush 24 supported by a front bracket 23 is installed at the front end of the gap between the two brush bodies. The belt-type brush 24 has a wide conveyor belt ring 26 tensioned and supported by two rollers 25. The lower section of the conveyor belt ring 26 is a horizontal conveyor belt section. Snow sweeping brushes 27 are provided at the center front and back of the outer edge of the conveyor belt ring 26. The front bracket 23 is fixedly connected to the support frame 1 of one of the brush bodies and extends forward from the sprocket shaft 4 closest to the belt-type brush 24 on that side of the brush body, serving as the drive shaft for the roller 25 on the corresponding side of the belt-type brush 24, so that the belt-type brush 24 and the chain-type brush 2 of the brush body on that side move in the same direction. When the snow sweeping brush 27 follows the conveyor belt ring 26 to the horizontal conveyor belt section, it sweeps the ground. The front support 23 also has two longitudinally extending guide wheels 28 with anti-reverse flanges at the rear of the lower section of the conveyor belt ring 26. The two guide wheels 28 are staggered left and right, and their surfaces press against the upper and lower surfaces of the lower section of the conveyor belt ring 26. A gap is left between the front end of the lower guide wheel 28 and the snow sweeping brush 27 to avoid interference. The anti-reverse flanges of the two guide wheels 28 press against the rear edge of the conveyor belt ring 26, thus preventing the conveyor belt ring 26 from rolling backward and causing operational failure when following the snow sweeper. By setting up a belt-type rolling brush 24, the snow in the cleaning dead corner between the two rolling brush bodies can be swept to one side first, and then cleaned by the rolling brush body on that side, thus avoiding snow accumulation in the cleaning dead corner between the two rolling brush bodies.

[0044] When this snowplow is in operation, the vehicle moves slowly forward on uncompacted snow-covered roads. First, the belt-type rolling brush 24 at the front of the vehicle sweeps the snow from the dead corner between the two main rolling brushes to one side. Then, the rolling brushes of the left and right snow-sweeping rollers at the front of the vehicle sweep the snow on the left and right sides respectively, and send it upwards along the inclined support plates 3 on both sides. The snow output from the discharge ports of the inclined support plates 3 on both sides of the vehicle is fed into the inlet of the primary spiral conveyor pipe 18, and then sequentially transported along the primary spiral conveyor pipe 18, the intermediate pipe joint 20, and the secondary spiral conveyor pipe 19. Finally, it is discharged into the truck bed 17 through the discharge pipe 21. Once the truck bed 17 is full of snow, it is transported to a designated location for unloading. When using this snowplow to clear snow on multi-lane roads, the swept snow will not accumulate on adjacent lanes, allowing for convenient clearing of multiple lanes one by one, thus freeing up multiple lanes for vehicles to pass and improving traffic efficiency.

[0045] The above illustrations are merely typical embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

The intermediate pipe joint between the primary spiral conveying pipe and the secondary spiral conveying pipe adopts a retractable and torsionable corrugated pipe joint. The universal bracket is equipped with a clamp to hold the pipe body of the primary spiral conveying pipe tightly. A downwardly extending vertical shaft is fixedly connected below the clamp. A transverse rotating shaft is mounted on the frame below the clamp by a pair of roller bearings. The middle part of the transverse rotating shaft is connected to the vertical shaft below the clamp in a cross shape by a spherical bearing.

8. The snowplow according to claim 6, characterized in that: The discharge pipe is equipped with a pipe seat that is fixedly connected to the discharge port of the secondary spiral conveyor pipe. A rotatable pipe head is connected to the pipe seat. The pipe body of the rotatable pipe head is formed by bending and connecting a connecting section pipe body and a pipe mouth section pipe body. The port of the connecting section pipe body is rotatably snapped onto the pipe seat through an annular groove. A large gear is fixedly fitted around the periphery of the connecting section pipe body. A small gear that meshes with the large gear and is driven by a control motor is installed around the periphery of the pipe seat. The orientation of the rotatable pipe head pipe mouth section pipe body is controlled by the control motor.

9. The snowplow according to claim 5, characterized in that: At the front end of the gap between the two main rolling brushes, a belt-type rolling brush supported by a front bracket is also provided. The belt-type rolling brush has a wide conveyor belt ring tensioned and supported by two rollers on the left and right. The lower section of the conveyor belt ring is a horizontal conveyor belt section. Snow-sweeping brushes are provided at the center front and back of the outer belt ring. The front bracket is fixedly connected to the support frame of one of the main rolling brushes and extends forward from the sprocket closest to the belt-type rolling brush on that side, serving as the drive shaft for the corresponding side roller of the belt-type rolling brush, so that the belt-type rolling brush and the roller on that side... The chain-type rolling brush of the brush body rotates in the same direction. When the snow sweeping brush follows the conveyor belt ring to the horizontal conveyor belt section, it sweeps the ground. The front bracket is also equipped with two longitudinally extending guide wheels with anti-backflow edges at the rear of the middle of the lower section of the corresponding conveyor belt ring. The two anti-backflow guide wheels are staggered from each other in the left and right positions. The wheel surfaces of the two anti-backflow guide wheels press against the upper and lower belt surfaces of the lower section of the conveyor belt ring, and there is a gap between the front end of the lower anti-backflow guide wheel and the snow sweeping brush. The anti-backflow edges of the two anti-backflow guide wheels press against the rear edge of the conveyor belt ring.
