Description

TECHNICAL FIELD

[0001] The application relates to the technical field of road snow removal equipment, in particular to a municipal road snow removal device. BACKGROUND

[0002] In winter, especially in cold regions, the snow accumulation on municipal roads has become a very thorny and urgent problem, which has a profound impact on the city's transportation system, residents' daily travel and the normal operation of the social economy.

[0003] The traditional snow removal method mainly relies on manual snow removal and simple mechanical snow removal. The efficiency of manual snow removal is extremely low, and a large amount of manpower and a long time are needed to complete the snow removal task. The simple mechanical snow removal device alleviates the pressure of manual snow removal to a certain extent, but also has obvious limitations. Common simple snow removal machines are mainly snow shovel structures, which are driven by vehicles or their own power to push the snow shovel on the road to shovel the snow away from the road surface. However, this kind of device has a single function and can only deal with loose snow. It is difficult to effectively remove the compacted snow and ice mixture formed by the compaction of snow and ice mixed with snow and ice. In actual application, a large amount of compacted snow and ice blocks are often left on the road. These residual ice and snow will quickly re-freeze to form a smooth ice surface when the temperature is low, causing vehicles to easily skid and lose control when driving, and pedestrians to risk falling and being injured, seriously threatening traffic safety.

[0004] Therefore, the application provides a municipal road snow removal device to solve the problems in the background art. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the snow removal effect of compacted snow and ice blocks, the application provides a municipal road snow removal device.

[0006] The municipal road snow removal device provided by the application adopts the following technical scheme: a fixed frame is arranged, wherein the bottom of the fixed frame is provided with a snow shovel, a snow removal mechanism for cleaning ice and snow is arranged on the fixed frame, a crushing mechanism for crushing ice and snow is arranged on the front side of the fixed frame, a connecting mechanism is arranged on the fixed frame, and the connecting mechanism is used for connecting the fixed frame with a vehicle body and adjusting the angle of the fixed frame.

[0007] Optionally, the snow removal mechanism includes a rotatable snow removal roller with a rotating scraper that is spirally shaped. Driven pulleys are located at both ends of the snow removal roller, and driving pulleys, corresponding to the driven pulleys, are located at both ends of the fixed frame. The driving pulleys are connected to their corresponding driven pulleys via belt drive. A rotating shaft is mounted on the fixed frame, and a driven gear is mounted on the rotating shaft. A first motor is mounted on the fixed frame, and a driving gear meshing with the driven gear is located at the output end of the first motor.

[0008] Optionally, the crushing mechanism includes a drive shaft rotatably connected to a fixed frame, a plurality of rotating cams are provided on the drive shaft, and a crushing component corresponding to each rotating cam and capable of crushing ice and snow is provided on the fixed frame. A second motor is fixedly provided on the fixed frame, and the output end of the second motor is fixedly connected to the drive shaft.

[0009] Optionally, the crushing assembly includes a U-shaped frame with a slidable sliding rod on it. A first compression spring is fitted onto the sliding rod, and the other end of the first compression spring is fixed to the U-shaped frame. The bottom of the sliding rod passes through the U-shaped frame and has a groove. A second compression spring is installed in the groove, and a slidable crushing rod is installed in the groove. The top of the crushing rod is fixedly connected to the second compression spring, and the bottom of the crushing rod is tapered.

[0010] Optionally, the connecting mechanism includes a mounting frame, on which a first hydraulic rod is mounted. The output end of the hydraulic rod is hinged to a connecting frame. The mounting frame has several hinge rods that are hinged to the connecting frame. When working, the first hydraulic rod can drive the connecting frame to swing up and down. The connecting frame is equipped with a swingable frame, on which a second hydraulic rod is hinged. The output end of the second hydraulic rod is hinged to the connecting frame. The swing frame is fixedly connected to a fixed frame. When working, the second hydraulic rod drives the swing frame to swing.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. This device is equipped with a snow removal roller and a rotating scraper. The rotation of the snow removal roller drives the spiral rotating scraper, which can effectively scrape up the snow on the road and transport it to one side, greatly improving the snow removal efficiency. Compared with traditional manual or simple mechanical snow removal methods, it can clear large areas of snow in a shorter time.

[0013] 2. The rotating cam in the crushing mechanism works in conjunction with the crushing component. When the drive shaft rotates, the rotating cam periodically squeezes the sliding rod in the crushing component, causing the crushing rod to move up and down. Its conical bottom can effectively crush the compacted ice and snow, avoiding the problem of large pieces of ice and snow remaining, which may cause road icing or affect subsequent snow removal operations, thus improving the thoroughness of snow removal.

[0014] 3. The connecting mechanism employs a combination of a first hydraulic rod and a second hydraulic rod. The first hydraulic rod drives the connecting frame to swing up and down, while the second hydraulic rod drives the swing frame to swing, thus achieving multi-degree-of-freedom adjustment when the fixed frame is connected to the vehicle body. This flexible connection method can adapt to different road conditions and vehicle body operation requirements. For example, on uneven roads, the height and angle of the snow removal device can be adjusted to ensure that the snow scraper and snow removal mechanism always maintain good contact with the road surface, improving snow removal efficiency and reducing damage to the road.

[0021] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limiting the present invention.

[0022] Reference Figure 1 One embodiment shown includes a fixed frame 1, a snow scraper 2 fixedly connected to the bottom of the fixed frame 1, a snow removal mechanism 3 for clearing snow, a snow breaking mechanism 4 for crushing snow, and a connecting mechanism 5 for connecting the fixed frame 1 to the vehicle body and adjusting the angle of the fixed frame 1. In this embodiment, the snow scraper 2 is installed at the bottom of the fixed frame 1 and directly contacts the road surface to remove snow during the movement of the device. The snow removal mechanism 3 is installed on the fixed frame 1 and is responsible for removing snow. The snow removal and transfer function prevents snow from accumulating on the road surface, ensuring basic road accessibility. The crushing mechanism 4 can crush relatively hard snow or snow-ice mixtures to prevent large pieces of snow and ice from causing subsequent road icing and other problems, further improving the snow removal effect and quality. The connecting mechanism 5 is the key part for connecting the snow removal device to the vehicle body. Through this mechanism, the snow removal device can move and operate on the road with the help of the vehicle body's power. The connecting mechanism 5 needs to have a certain degree of flexibility and stability to adapt to the needs of different vehicle bodies and road conditions.

[0023] Reference Figure 2 , Figure 3One embodiment shown is as follows: The snow removal mechanism 3 includes a rotatable snow removal roller 6, a rotating scraper 7 fixedly connected to the snow removal roller 6, the rotating scraper 7 having a spiral shape, driven pulleys 8 fixedly connected to both ends of the snow removal roller 6, and driving pulleys 9 corresponding to the driven pulleys 8 rotatably connected to both ends of the fixed frame 1, the driving pulleys 9 and their corresponding driven pulleys 8 being connected via belt drive, a rotating shaft 10 rotatably connected to the fixed frame 1, a driven gear 11 fixedly connected to the rotating shaft 10, a first motor 12 fixedly connected to the fixed frame 1, and a driving gear 13 meshing with the driven gear 11 fixedly connected to the output end of the first motor 12. In this embodiment, the snow removal roller 6 is the core component for snow removal, and its spiral shape... The rotating scraper 7 utilizes a special spiral structure to effectively roll up the snow in front and push it to one side when the snow removal roller 6 rotates, thus achieving snow removal and centralized collection. The driven pulleys 8 at both ends of the snow removal roller 6 are connected to the driving pulleys 9 at both ends of the fixed frame 1 via belt drive. This transmission method can stably transmit power and ensure the normal rotation of the snow removal roller 6. The rotating shaft 10, driven gear 11, first motor 12, and driving gear 13 constitute the power drive system of the snow removal roller 6. The first motor 12 serves as the power source and transmits power to the rotating shaft 10 through gear transmission. The rotating shaft 10 then transmits power to the snow removal roller 6 through belt drive, thereby enabling the snow removal roller 6 to rotate at a predetermined speed and direction to complete the snow removal operation.

[0024] The implementation principle of this application embodiment is as follows: the first motor 12 serves as a power source, and transmits power to the rotating shaft 10 through gear transmission. The rotating shaft 10 then transmits power to the snow removal roller 6 through belt transmission. When the snow removal roller 6 rotates, the spiral rotating scraper 7 on the snow removal roller 6, due to its special spiral structure, can gradually roll in the snow in front and push it to one side along the spiral direction of the scraper, thereby realizing the clearing and centralized collection of snow and improving snow removal efficiency.

[0025] Reference Figure 3 , Figure 4One embodiment shown is as follows: The crushing mechanism 4 includes a drive shaft 14, which is rotatably connected to a fixed frame 1. Several rotating cams 15 are fixedly connected to the drive shaft 14. The fixed frame 1 is equipped with crushing components 16, each corresponding to one of the rotating cams 15 and capable of crushing ice and snow. A second motor 28 is fixedly mounted on the fixed frame 1, and its output end is fixedly connected to the drive shaft 14. In this embodiment, the drive shaft 14 serves as the power transmission component of the crushing mechanism 4. Rotatingly connected to the fixed frame 1, it can stably rotate on the fixed frame 1. The rotating cams 15 on the drive shaft 14 are key components for achieving the crushing function. When the drive shaft 14 rotates, the rotating cams 15 move in a circular motion. The crushing components 16 correspond one-to-one with the rotating cams 15. Under the periodic action of the rotating cams 15, the crushing components 16 can crush the ice and snow, thereby effectively processing compacted snow and ice-snow mixtures.

[0026] Reference Figure 4 , Figure 5 One embodiment shown is as follows: the crushing assembly 16 includes a U-shaped frame 17, on which a sliding rod 18 that can slide up and down is slidably connected. A first compression spring 19 is fixedly fitted onto the sliding rod 18, and the other end of the first compression spring 19 is fixed to the U-shaped frame 17. The bottom of the sliding rod 18 passes through the U-shaped frame 17 and has a groove 20. A second compression spring 21 in the vertical direction is fixedly connected within the groove 20. A slidable crushing rod 22 is slidably connected within the groove 20. The top of the crushing rod 22 is fixedly connected to the second compression spring 21, and the bottom of the crushing rod 22 is tapered. In this embodiment, the U-shaped frame 17 serves as a support structure for the crushing assembly 16, providing a mounting base for other components. The slidable sliding rod 18 is mounted on the U-shaped frame 17 and fitted with the first compression spring 19. The elasticity of the first compression spring 19 allows the sliding rod 18 to return to its initial position when no external force is applied or when the external force disappears. The bottom of the sliding rod 18 passes through the U-shaped frame 17 and is provided with a groove 20. The second compression spring 21 in the groove 20 is connected to the breaking rod 22. When the protruding part of the rotating cam 15 contacts the sliding rod 18, the sliding rod 18 slides upward to compress the first compression spring 19. At the same time, the structure in the groove 20 drives the breaking rod 22 to move upward to compress the second compression spring 21. When the protruding part of the rotating cam 15 leaves the sliding rod 18, the first compression spring 19 and the second compression spring 21 rebound, causing the sliding rod 18 and the breaking rod 22 to move downward. The conical bottom of the breaking rod 22 generates an impact force on the ice and snow, achieving the breaking of the ice and snow. The conical design at the bottom of the breaking rod 22 can more effectively concentrate the force and improve the breaking effect.

[0027] The implementation principle of the above embodiment is as follows: When the drive shaft 14 rotates, the rotating cam 15 on it performs circular motion. When the protruding part of the rotating cam 15 contacts the sliding rod 18 of the crushing assembly 16, an upward thrust is applied to the sliding rod 18. The sliding rod 18 slides upward within the U-shaped frame 17, compressing the first compression spring 19 and driving the crushing rod 22 upward through the structure within the slide groove 20. When the protruding part of the rotating cam 15 leaves the sliding rod 18, the first compression spring 19 rebounds, pushing the sliding rod 18 downward to reset. At the same time, the crushing rod 22 also moves downward under the action of the second compression spring 21, and its conical bottom generates an impact force on the ice and snow, thereby breaking the ice and snow. The cooperation of multiple rotating cams 15 and the crushing assembly 16 enables continuous crushing of ice and snow at different locations on the road.

[0028] Reference Figure 1 , Figure 4 , Figure 5 One embodiment shown is as follows: The connecting mechanism 5 includes a mounting frame 23, on which a first hydraulic rod 24 is hinged. The output end of the hydraulic rod is hinged to a connecting frame 25. Four hinged rods are provided on the mounting frame 23 and are hinged to the connecting frame 25. When working, the first hydraulic rod 24 can drive the connecting frame 25 to swing up and down. A swingable frame 26 is hinged to the connecting frame 25. A second hydraulic rod 27 is hinged to the swing frame 26. The output end of the second hydraulic rod 27 is hinged to the connecting frame 25. The swing frame 26 is fixedly connected to the fixed frame 1. When working, the second hydraulic rod 27 drives the swing frame 26 to swing. In this embodiment, the mounting frame 23 is used to connect the connecting mechanism 5 to the vehicle body and is the starting point of the entire connection. The first hydraulic rod 24 is hinged to the connecting frame 25 through its output end... The hinge rod on the mounting bracket 23 is connected to the connecting bracket 25 at multiple hinge points, forming a height-adjustable connection structure. When the first hydraulic rod 24 extends or retracts, it can change the angle between the connecting bracket 25 and the mounting bracket 23, thereby realizing the height adjustment of the fixed bracket 1 in the vertical direction. This allows the snow removal device to adapt to different road height differences and vehicle suspension systems. The hinged connection between the swing bracket 26 on the connecting bracket 25 and the second hydraulic rod 27, as well as the fixed connection with the fixed bracket 1, forms an angle-adjustable structure. When the second hydraulic rod 27 extends or retracts, the swing bracket 26 swings relative to the connecting bracket 25, thereby driving the fixed bracket 1 to adjust its angle in the horizontal direction. This allows the snow removal device to flexibly adjust the snow removal angle on curves or uneven roads, ensuring good contact between the snow removal device and the road surface, improving the snow removal effect and reducing damage to the road.

[0029] The working principle of this device is as follows: When performing snow removal operations on municipal roads, the mounting frame 23 of the connecting mechanism 5 is first fixed to the vehicle body. The posture of the fixing frame 1 is adjusted by operating the first hydraulic rod 24 and the second hydraulic rod 27 to ensure good contact between the snow scraper 2 and the snow removal mechanism 3 and the road surface. Then, the first motor 12 is started, and the snow removal roller 6 begins to rotate. The rotating scraper 7 scrapes up and transports the snow. At the same time, the transmission shaft 14 drives the rotating cam 15 to rotate, and the crushing component 16 crushes the ice and snow. Throughout the process, the hydraulic rods of the connecting mechanism 5 are adjusted in real time according to the actual road conditions to ensure that the snow removal device operates continuously, efficiently, and stably, and to effectively clean up the snow and ice mixture on municipal roads.

[0030] The working principle of this device has been explained through the above embodiments. These embodiments merely illustrate several implementation methods of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
