Description

Technical Field

[0001] The present application relates to the technical field of snow removal devices, and in particular to an unmanned automatic snow removal device for road surfaces. Background Art

[0002] Due to the heavy snowfall in northern my country in winter and the lower temperature compared to the southern provinces, if the snow on the road is not dealt with in time after snowfall, it is easy for the road surface to freeze into blocks, which greatly weakens the friction between moving vehicles and pedestrians and the road surface, thereby increasing the probability of road traffic accidents.

[0003] In the prior art, snowplows are used to clear snow on roads. Such snowplows can only rely on the snow shovel in front of the vehicle to push the snow on the road forward during the snow removal process. The single snow removal method causes the snow to gradually accumulate in front of the vehicle body, thereby increasing the resistance of the vehicle body to move forward, and thus seriously affecting the snowplow's snow-pushing effect. In order to reduce the forward resistance of the vehicle body, the vehicle body needs to frequently change its forward direction so that the snow shovel pushes the snow in different directions, thereby affecting the snow removal efficiency. Especially for narrow roads, it is inconvenient for snowplows to frequently change their forward direction, which restricts their use effect. Utility Model Content

Figure 1-Figure 5 The embodiment of the present application provides an unmanned automatic snow removal device for a road surface, including a movable device box 100, a snow shoveling base plate 200 and a snow shoveling recovery component 300.

[0035] Among them, a working surface gap 110 for shoveling and collecting snow is opened on one side of the forward direction of the device box 100, and a snow shoveling base plate 200 is provided at the bottom end of the working surface gap 110 of the device box 100. When the device box 100 moves forward, the snow shoveling base plate 200 can shovel snow and allow the shoveled snow to pass through the working surface gap 110 and enter the device box 100. A snow shoveling recovery component 300 is installed in the device box 100 and is located above and behind the snow shoveling base plate 200. The snow shoveling recovery component 300 is connected to the driving component 400 and is driven to rotate by the driving component 400. The snow shoveling recovery component 300 can roll the snow at the working surface gap 110 into the device box 100 when rotating.

[0036] The unmanned road automatic snow removal device provided by the embodiment of the present application includes a movable device box 100, a snow shoveling base plate 200 and a snow shoveling recovery component 300. The embodiment of the present application opens a working surface notch 110 on one side of the forward direction of the device box 100, and the device box 100 is provided with a snow shoveling base plate 200 at the bottom end of the working surface notch 110. When in use, the snow shoveling base plate 200 can not only shovel the snow on the road in front of the working surface notch 110 by relying on the movement of the device box 100, so that the snow on the road is gradually pushed forward, but also can make part of the pushed snow pass through the snow shoveling base plate 200 and enter the device box 10 from the working surface notch 110. 0, thereby slowing down the accumulation of snow in front of the device box 100 and reducing the forward resistance of the device box 100. This avoids the need to frequently change the forward direction due to the gradual accumulation of snow during the pushing process, thereby improving the snow removal efficiency. In addition, the device box 100 is equipped with a snow shoveling and recovery assembly 300 located above and behind the snow shoveling base plate 200. Under the drive of the drive assembly 400, the snow shoveling and recovery assembly 300 rotates and cooperates with the snow shoveling base plate 200 to more quickly reel snow from the working surface gap 110 into the device box 100. This not only reduces the forward resistance of the device box 100, but also facilitates the subsequent processing of the snow recovered in the device box 100. In addition, the unmanned road automatic snow removal device provided in the embodiment of the present application can clear snow on the road when it is turned on, eliminating the need for human staff to be on duty at the snow removal device for continuous monitoring.

[0037] Optionally, the snow shoveling base 200 adopts a structure with an obtuse triangle in longitudinal section, and the front side of the snow shoveling base 200 is an inclined surface inclined forward and downward, so that the snow on the bottom surface can be shoveled more easily, and the rear side of the snow shoveling base 200 is an inclined surface inclined rearward and downward, so that the snow can easily enter the device box 100 along this inclined surface, and the length of the inclined surface of the front part of the snow shoveling base 200 is smaller than the length of the inclined surface of the rear part.

[0038] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 As shown, the snow shoveling and recovery assembly 300 includes a first rotating shaft 310 and a rotating shovel 320. The first rotating shaft 310 is rotatably connected to the left and right sides of the device box 100. The first rotating shaft 310 is fixedly connected to the output end of the drive assembly 400, and the rotating shovel 320 is fixedly connected to the shaft of the first rotating shaft 310. During use, the output end of the drive assembly 400 drives the first rotating shaft 310 to rotate, and the rotating shovel 320 on the first rotating shaft 310 also rotates accordingly. During the rotation of the rotating shovel 320, its own rotation continuously draws in snow, thereby alleviating the accumulation of snow in front of the device box 100.

[0039] In some embodiments, the rotating shovel 320 is composed of 4-6 shovel plates 321 that are evenly distributed in an annular direction on the shaft body of the first rotating shaft 310. One end of the shovel plate 321 is fixedly connected to the first rotating shaft 310, and the other end of the shovel plate 321 is provided with a folding edge 3211. When the rotating shovel 320 rotates, the snow between the shovel plates 321 on the shaft body of the first rotating shaft 310 also rotates and is then brought into the device box 100. The setting of the folding edge 3211 enables the rotating shovel 320 to dig the snow at the notch 110 on the working surface when it rotates, thereby better clearing the accumulated snow.

[0040] In some embodiments, the interior of the device box 100 is also provided with a snow-clearing component 500 for discharging the snow collected inside the device box 100 to the outside of the box. The snow-clearing component 500 is arranged behind the snow shoveling and recovery component 300. The snow-clearing component 500 is connected to the driving component 400. When the driving component 400 is working, it drives the snow-clearing component 500 to operate, so that the snow collected inside the device box 100 is discharged to the outside of the device box 100, thereby better clearing the snow on the road after clearing the snow inside the device box 100.

[0041] Among them, such as Figure 2 and Figure 3 As shown, the snow removal component 500 includes a second rotating shaft 510, a reciprocating screw 520, a slider 530, a fixed rod 540 and a cleaning push plate 550; the second rotating shaft 510 is rotatably connected to the left and right sides of the device box 100 and is arranged parallel to the first rotating shaft 310, the second rotating shaft 510 is connected to the driving component 400 and can rotate under the driving action of the driving component 400, the reciprocating screw 520 is fixedly connected to the shaft body of the second rotating shaft 510, the reciprocating screw 520 is slidably connected to the slider 530 that can move back and forth left and right, the bottom end of the slider 530 is fixedly connected to the fixed rod 540, the fixed rod 540 is connected to the cleaning push plate 550 that can move with the slider 530, and the left and right sides of the device box 100 are respectively provided with discharge ports 700 for discharging snow in the box.

[0042] When in use, when the driving assembly 400 drives the first rotating shaft 310 of the snow shoveling and recycling assembly 300 to rotate, it also drives the second rotating shaft 510 to rotate. When the second rotating shaft 510 rotates, it drives the reciprocating screw rod 520 to rotate together. Since the reciprocating screw rod 520 is used, the slider 530 slidably connected to the reciprocating screw rod 520 can realize reciprocating motion without changing the rotation direction of the second rotating shaft 510. When the slider 530 reciprocates, the fixed rod 540 fixed to the slider 530 and the cleaning push plate 550 connected to the fixed rod 540 also reciprocate together. When the cleaning push plate 550 reciprocates left and right in the device box 100, the snow collected in the device box 100 is continuously pushed to the left and right sides. Then, under the pushing action, the snow can be discharged out of the device box 100 through the discharge port 700. In this way, the snow accumulated in the forward direction of the device box 100 is transferred to the two sides of the road after being cleaned, so that the device box 100 can continue to be used.

[0043] As an optional method of the embodiment of the present application, Figure 1 As shown, the device box 100 is connected to an opening and closing door 710 at two discharge ports 700 through electric valves, so that when the electric valves are opened, the opening and closing doors can be pushed open by the snow in the device box 100, thereby timely cleaning and discharging the snow in the device box 100.

[0044] Optionally, two cleaning push plates 550 are fixedly connected to the fixing rod 540, and the two cleaning push plates 550 can be further fixedly connected together by a connecting rod. The cleaning push plates 550 should be vertically aligned to ensure that the bottom ends of the cleaning push plates 550 can reach the inner bottom surface of the device box 100 as much as possible and maintain an appropriate gap with the inner bottom surface of the device box 100.

[0045] In some embodiments, as Figure 1-Figure 3 As shown, the driving assembly 400 is disposed outside the device box 100 , and the driving assembly 400 includes a motor 410 , a fixing base 420 , a driving pulley 430 , a driven pulley 440 and a belt 450 .

[0046] Among them, a fixing base 420 is fixedly installed on the outside of the device box 100, and a motor 410 is fixedly installed on the fixing base 420. The output shaft of the motor 410 is connected to the first rotating shaft 310 extending out of the device box 100. The first rotating shaft 310 is fixed with a driving wheel 430 on one end outside the device box 100. The driving wheel 430 is connected to the driven wheel 440 on the same side as the driving wheel 430 through a belt 450. One end of the second rotating shaft 510 extends out of the device box 100 and is fixedly connected to the driven wheel 440.

[0047] In this embodiment, the drive assembly 400 uses a driving wheel 430, a driven wheel 440 and a belt 450 to synchronize the rotation of the first rotating shaft 310 and the second rotating shaft 510, thereby achieving the effect of a set of driving equipment driving the two rotating shafts to rotate at the same time, and the drive assembly 400 is located outside the device box 100, which is convenient for maintenance and inspection.

[0048] In some embodiments, the top end of the slider 530 is fixedly connected to the limit block 531, and a limit groove 600 is provided on the rear side surface inside the device box 100 for the limit block 531 to move back and forth left and right. The limit block 531 is slidably connected in the limit groove 600, so that the slider 530 is not only stable when moving back and forth on the reciprocating screw 520, but also enables the cleaning push plate 550 that moves with the slider 530 to move back and forth within an appropriate range.

[0049] In some embodiments, the unmanned automatic road snow removal device of the embodiment of the present application further includes a snow melting and cleaning component 800 for cleaning the residual snow inside the device box 100.

[0050] After the unattended automatic snow removal device for a road surface is used for a long time, snow will remain inside the device box 100. When the snow removal device is maintained and cleaned, the snow melting and cleaning component 800 can be used to clean the remaining snow inside the device box 100.

[0051] In this embodiment, if Figure 1 、 Figure 2 and Figure 5As shown, the snow melting and clearing assembly 800 includes a water tank 810, a water pump 820, and a nozzle 830. The water tank 810 is arranged at the rear side of the device box 100. The water tank 810 contains water. The water tank 810 can be covered with an insulation layer to prevent the water in the water tank 810 from freezing and affecting its use. The water pump 820 is fixedly installed on the water tank 810 and can also be protected by anti-freezing measures. The water inlet of the water pump 820 is connected to the water tank 810 through a connecting pipe. The water outlet of the water pump 820 is connected to the nozzle 830 located in the device box 100 through a connecting pipe. The nozzle 830 is located at the upper part of the device box 100 and has multiple high-pressure nozzles at the bottom end. During use, the water pump 820 is turned on to draw water from the water tank 810 and deliver it to the nozzle 830 via a connecting pipe. The water is then sprayed out through multiple high-pressure nozzles provided at the bottom of the nozzle 830. The sprayed water cleans the interior of the device box 100. Additionally, an appropriate amount of snow removal agent may be added to the water tank 810 to improve the cleaning effect of residual snow within the device box 100. Furthermore, the snow removed from the device box 100, upon encountering the water containing the snow removal agent, can be melted more quickly. The melted snow water can also be reused. Under the reciprocating action of the cleaning push plate 550, the melted snow water is also discharged outside the device box 100, where it comes into contact with the discharged snow, thereby accelerating the melting of the discharged snow and improving the snow removal effect.

[0052] In some embodiments, as Figure 1 As shown, a slope plate 720 is provided below the discharge port 700 so that the snow discharged from the discharge port 700 can fall along the slope plate.

[0053] In some embodiments, a heater for heating water is installed in the water tank 810 (omitted and not shown in the drawings) to ensure that the water in the water tank 810 will not be frozen and affect its use when the temperature is low. Moreover, after the snow removal agent is added to the water tank 810, the water is heated to a suitable temperature, which can further improve the snow removal effect.

[0054] In some embodiments, as Figure 1As shown, an electric roller 900 is installed at the bottom of the device box 100, so that the device box 100 can move forward. In actual applications, the movable device box 100 can use unmanned driving technology to enable the device box 100 to navigate autonomously and move forward according to a predetermined designed path line, so as to remove snow. When applied, it can be used on roads where no one walks or few people walk. Optionally, an industrial computer is set on the outside of the device box 100 for autonomous navigation and path planning. At the same time, a laser radar, a visual camera and a positioning system are installed on the device box 100 to cooperate with the industrial computer for better intelligent application. Since the problem to be solved by the snow removal device provided in this application is not how to achieve unmanned driving, it will not be elaborated on here. However, it can be imagined that with the widespread application of unmanned driving technology, there will definitely be more and more unmanned snowplows.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
