Description

Technical Field

[0001] The invention relates to the technical field of road cleaning, in particular to a self-cleaning adjustable road snow-clearing roller brush. Background Art

[0002] Snow accumulation on roads in winter seriously affects traffic safety and efficiency. Traditional snow-clearing roller brushes are the mainstream snow-removal equipment. The existing roller brushes rely on the operator's experience to manually adjust the ground clearance of the roller brush, and lack real-time detection components (such as snow thickness sensors and ground contact detection mechanisms). When encountering new snow, the fixed-height roller brush has too much ground clearance, and the bristles cannot fully cut into the snow layer, resulting in a large amount of snow remaining. When faced with a thin layer of compacted snow or icy roads, if the roller brush is not raised in time, the continuous friction between the bristles and the hard road surface will cause the roots of the bristles to break, and maintenance costs will increase sharply. In addition, the local fluctuations caused by uneven road surfaces (such as cracks in asphalt roads and joints in cement roads) will cause the fixed-height roller brush to produce periodic "suspension-impact" movements, further exacerbating bristle wear and spindle bearing fatigue. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention provides a self-cleaning adjustable road snow-clearing roller brush, which has the advantage of clearing snow of different thicknesses and solves the problems of residual snow caused by excessive gap between the roller brush and the snow, and rapid wear of the bristles caused by excessive contact.

[0014] By means of the above technical solution, the present invention provides a self-cleaning adjustable road snow-clearing roller brush, which has at least the following beneficial effects:

[0015] 1. This self-cleaning adjustable snow-clearing roller brush has an electric telescopic rod with a free end that can adjust the distance between the roller brush and the ground.

[0018] 4. The self-cleaning adjustable road snow-clearing roller brush uses hot air to increase the temperature of the brush bristles and quickly melt the snow and ice.

[0019] 5. This self-cleaning adjustable road snow removal roller brush can adjust the position of the cleaning claws according to actual conditions when cleaning is needed, so that it can better adapt to different cleaning needs. It can perform targeted cleaning according to the actual contamination situation of the roller brush, thereby improving the effectiveness of cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The following describes the self-cleaning adjustable road snow-clearing roller brush provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0036] Example 1:

[0037] Snow accumulation will significantly reduce the friction coefficient of the road surface, causing vehicles to slip and extend the braking distance, which can easily lead to accidents such as rear-end collisions and rollovers. Timely snow removal can greatly improve driving safety and reduce the accident rate. In order to solve the above problems, combined with Figure 1 、 Figure 2 and Figure 5 As shown, the self-cleaning adjustable road snow-clearing roller brush provided by the present invention includes a suspension 100 mounted on a vehicle body, a protective cover 101 mounted on the suspension 100, a roller brush 102 disposed within the protective cover 101, a transmission mechanism 200 for adjusting the distance between the roller brush 102 and the ground provided on the protective cover 101, an adjustment mechanism 300 for adjusting the angle of the roller brush 102, and a cleaning mechanism 400 for cleaning the roller brush 102 provided on the suspension 100. During the rotation of the roller brush 102, entangled snow, ice, and debris (such as branches and plastic bags) are simultaneously cleared without manual intervention, thus avoiding the problem of traditional equipment requiring shutdown and disassembly for cleaning every 1-2 hours of operation.

[0038] The ground clearance cannot be dynamically adjusted according to changes in snow thickness, which reduces snow clearing efficiency and increases equipment wear, making it difficult to achieve adaptive control of snow clearing operations. To solve the above problems, the transmission mechanism 200 includes an electric telescopic rod 202 installed on both sides of the protective cover 101. A main shaft 103 is rotatably installed between the free ends of the two electric telescopic rods 202 through bearings. The roller brush 102 is sleeved on the main shaft 103. The protective cover 101 is provided with a detection component 203 for sensing the thickness of snow. The detection component 203 can detect the thickness of snow. Subsequently, the free end of the electric telescopic rod 202 can be extended and retracted to adjust the distance between the roller brush 102 and the ground, and can adapt to different snow thicknesses (such as a thin snow compaction layer vs. new snow) and road surface flatness (bumpy road surface, icy road surface), thereby avoiding excessive wear or missed brushing of the roller brush 102.

[0039] The detection component 203 includes a transmission frame 2031 at the front of the protective cover 101, and a connecting rod 2034 is slidably connected to the transmission frame 2031. A support seat 2035 is fixed to the bottom of the connecting rod 2034, and a roller 2036 is rotatably installed on the support seat 2035. A sensing rod 2037 is fixed to the top of the connecting rod 2034. A linear displacement sensor 2038 corresponding to the sensing rod 2037 is fixed in the transmission frame 2031. When the roller 2036 floats up and down with the change of snow thickness, the sensing rod 2037 slides synchronously in the transmission frame 2031. The linear displacement sensor 2038 detects the real-time position of the sensing rod 2037 and outputs an electrical signal corresponding to the snow thickness to the equipment controller. The controller drives the electric telescopic rod to adjust the length according to preset parameters, thereby dynamically adjusting the ground clearance of the roller brush 102 to achieve adaptive control of the snow clearing operation.

[0040] Specifically, a partition 2033 is fixedly connected to the transmission frame 2031, and the partition 2033 is slidably connected to the connecting rod 2034. A spring 2032 is fixedly connected between the partition 2033 and the bottom of the transmission frame 2031. When there is no snow or the snow becomes thinner, the elastic force of the spring 2032 pushes the connecting rod 2034 to reset, so that the roller 2036 is always in contact with the ground, ensuring that the detection component 203 can sense the ground undulations and changes in snow thickness in real time, avoiding detection delays or failures caused by rigid connections.

[0041] According to the embodiment, the sensing rod 2037 is linked to the bottom roller 2036 through the connecting rod 2034. When the roller 2036 floats up and down with the change of snow thickness, it drives the sensing rod 2037 to slide. The sensor converts the linear displacement of the sensing rod 2037 into an electrical signal (such as voltage or digital signal) and transmits it to the device controller; the controller processes the received signal, converts it into the actual snow thickness, and compares it with the preset roller brush 102 height parameter (such as the ground clearance corresponding to different snow thicknesses), and outputs a control signal to the electric extension. The drive system of the retractable rod; the drive system adjusts the extension and retraction amount of the electric telescopic rod according to the instructions, thereby dynamically adjusting the distance between the roller brush 102 and the ground (such as shortening the telescopic rod to lower the height of the roller brush 102 when the snow accumulates thicker, and extending the telescopic rod to increase the height of the roller brush 102 when the snow accumulates thinner); during the adjustment process, the sensor continuously collects the position signal of the sensing rod 2037 and feeds it back to the controller, forming a closed-loop control of "detection-processing-execution-feedback", ensuring that the height of the roller brush 102 always matches the real-time snow thickness, realizing adaptive adjustment of the snow clearing operation.

[0042] Example 2:

[0043] If the power source moves up and down with the roller brush 102, the connecting parts of the drive system (such as power lines, control lines, and transmission mechanisms) will be frequently subjected to tensile and bending stresses, which may easily lead to cable breakage, misalignment of transmission parts, or increased wear. In order to solve the above problems, the roller brush 102 is combined with the connecting parts of the drive system to form a roller brush. Figure 2-Figure 4 As shown, on the basis of Example 1, a frame 201 is fixedly connected to one side of the protective cover 101, a motor 204 is fixedly installed on the frame 201, and a sleeve 205 is fixedly connected to the output end of the motor 204, and a load-bearing bar 207 is fixedly connected to the output shaft of one of the electric telescopic rods 202, and a slide bar 206 is rotatably installed on the load-bearing bar 207, and the ends of the main shaft 103 and the slide bar 206 are fixedly connected with a bevel gear 208 for meshing transmission, and the slide bar 206 is slidably connected to the sleeve 205, and the motor 204 drives the sleeve 205 to rotate, and the slide bar 206 rotates with the sleeve 205, and the slide bar 206 drives the main shaft 103 to rotate through the bevel gear 208, and the main shaft 103 drives the roller brush 102 to rotate to clean the snow on the ground. While the slide bar 206 moves up and down, it can also drive the roller brush 102 to rotate normally.

[0044] Specifically, both sides of the slide rod 206 are fixedly connected to the limit blocks 209 , the inner wall of the sliding sleeve 205 is slidably connected to the limit blocks 209 through a sliding groove, and the sliding sleeve 205 drives the slide rod 206 to rotate through the limit blocks 209 .

[0045] According to the embodiment, the vertical rotation of the slide bar 206 is converted into the horizontal rotation of the roller brush 102, which adapts to the spatial layout inside the protective cover 101 and makes the driving structure compact and efficient. Even if the slide bar 206 moves up and down due to height adjustment, the bevel gear 208 always remains in an engaged state, ensuring that the rotation speed of the roller brush 102 is not affected by the height adjustment and maintaining a stable snow clearing efficiency.

[0046] Example 3:

[0047] Combine Figure 6 As shown, based on the first embodiment, the adjustment mechanism 300 includes a second motor 301 fixed on the suspension 100, the output end of the second motor 301 is fixedly connected to the connecting frame 302, the protective cover 101 is fixed to the connecting frame 302, and the second motor 301 starts to drive the connecting frame 302 to deflect, which can adjust the angle of the roller brush 102 to adapt to different scenarios for clearing snow.

[0048] Specifically, both sides of the suspension 100 are hinged with limit bars 303 , and a sliding sleeve hinged to the protective cover 101 is slidably connected to the limit bar 303 .

[0049] According to the embodiment, when working at the edge of the road, on a curve or on a slope, adjusting the angle of the roller brush 102 can keep it in the best fit with the road surface at all times, reduce blind spots for snow removal, and avoid problems such as residual snow or equipment collision with curbstones due to fixed angles.

[0050] Example 4:

[0051] Combine Figure 6-Figure 8 As shown, based on the first embodiment, the cleaning mechanism 400 includes a guide box 402 fixedly connected to the protective cover 101. A plurality of air outlet pipes 403 are connected to the side of the guide box 402 close to the roller brush 102. A hot air blower 401 is fixedly mounted on the suspension 100. The hot air blower 401 is connected to the guide box 402 through a pipe. The hot air generated by the hot air blower 401 is transported to the guide box 402 through the pipe and then blown to the roller brush 102 through the plurality of air outlet pipes 403. During snow clearing operations, the bristles of the roller brush 102 are easily adhered to by accumulated snow and ice. The hot air can increase the temperature of the bristle surface and quickly melt the accumulated snow and ice. Especially in cold weather, this thermal melting effect can effectively prevent the accumulated snow from further freezing and accumulating on the bristles, thereby ensuring the normal working performance of the roller brush 102.

[0052] Specifically, a cleaning claw 405 is hingedly connected to the outside of the protective cover 101. A second electric telescopic rod 404 is mounted on the suspension 100. The cleaning claw 405 is hingedly connected to the free end of the second electric telescopic rod 404. The second electric telescopic rod 404 can control the position and range of motion of the cleaning claw 405. When cleaning is not required, the cleaning claw 405 can be moved away from the roller brush 102 to avoid affecting the normal operation of the roller brush 102. When cleaning is required, the position of the cleaning claw 405 can be adjusted according to the actual situation, making it more suitable for different cleaning needs. It can perform targeted cleaning based on the actual contamination level of the roller brush 102, thereby improving cleaning effectiveness.

[0053] Furthermore, the air outlet pipes 403 are evenly distributed along the axial direction of the roller brush 102 , and the air outlet direction of the air outlet pipes 403 forms an angle of 30°-60° with the tangent of the rotation direction of the roller brush 102 .

[0054] It can be seen from the above embodiments that: after the equipment is started, the roller 2036 of the detection component 203 floats up and down as the thickness of the snow on the road changes, and drives the sensing rod 2037 to slide in the transmission frame 2031 through the connecting rod 2034. The linear displacement sensor 2038 detects the position of the sensing rod 2037 in real time and outputs an electrical signal to the controller. The controller converts the actual snow thickness and compares it with the preset parameters, drives the electric telescopic rod 202 to adjust the length to dynamically adjust the ground clearance of the roller brush 102. At the same time, the roller brush 102 rotates to clean the snow on the ground. When the roller brush 102 rotates, the hot air blower 401 on the suspension 100 transports the hot air through the pipe to the guide box 402 on the protective cover 101, and the hot air is evenly distributed along the axial direction of the roller brush 102 and the air outlet direction is the same as that of the roller brush 102. The air outlet pipe 403 with an angle of 30°-60° on the rotating tangent of the roller brush 102 blows towards the bristles to melt the adhered snow and ice. At the same time, the electric telescopic rod 204 drives the cleaning claw 405 hinged on the outside of the protective cover 101 to adjust its position as needed to remove stubborn debris such as branches and plastic bags entangled on the bristles. During the operation, the detection component 203 continuously feeds back the snow thickness signal, and the controller adjusts the height and angle of the roller brush 102 in real time to ensure that the roller brush 102 always fits the road surface in the best condition and efficiently removes snow of different thicknesses and types. After the operation is completed, the electric telescopic rod 102 extends to raise the roller brush 102, the motor 201 resets the angle of the roller brush 102, the cleaning claw 405 and the hot air system stop working, and the equipment enters standby mode.
