Figure 5 As shown, the crawler 111 preferably adopts anti-skid chain links 1111 to cope with the rough and slippery road conditions in the snow removal environment, thereby improving the travel stability of the snowplow. Secondly, the spring steel plate 1112 inside the crawler 111 can automatically adjust the inclination angle of the roller inside the crawler 111 to maintain the stable travel of the snowplow and the stable operation of the snow removal system 2. The chassis 112 is provided with a vehicle body above, and a plurality of telescopic legs are vertically provided at the bottom of the chassis 112. For example, two telescopic legs can be respectively provided at the front and rear ends of the bottom of the chassis 112. Telescopic legs. When the snowplow falls into the trap, the telescopic legs can be controlled to extend to prop up the fallen snowplow, thereby ensuring that the snowplow can escape in time. The telescopic legs are preferably hydraulic rods 121. The hydraulic rods 121 are connected to the hydraulic system of the snowplow. The hydraulic system includes a hydraulic oil tank 1122, a hydraulic oil delivery pipeline 1123 and a hydraulic valve 122 arranged on the chassis 112. When it is necessary to escape from the trap, the hydraulic valve 122 of the hydraulic system is opened to allow the hydraulic oil to enter the hydraulic rod 121, thereby controlling the extension of the hydraulic rod 121.

[0057] The snow removal system 2 includes a front snow removal device 21 disposed at the front of the vehicle body. The front snow removal device 21 is preferably rotatably connected to the vehicle body through a rotating rod to adapt to rugged roads, such as Figure 6 and Figure 7 As shown, the front-end snow removal device 21 includes a shell 211, a front-end snow removal driving component and a double-helical snow removal blade 214.

One end of the pipe shell 311 is connected to the snow collecting inlet 2112, and the other end is connected to the snow collecting box 34. When the snow collecting and conveying motor 35 drives the rotating shaft to rotate, the power is transmitted to the worm gear 32, and then the spiral piece 312 is driven to rotate in the snow conveying pipe 31 to roll the removed snow into the snow collecting box 34. Through the heating of the heater 33, water can be stored in the snow collecting box 34, realizing the recycling of resources and environmental protection. In addition, a water level sensor can be provided in the snow collecting box 34. If the water level reaches the limit position, the spiral blade 312 in the snow conveying pipe 31 stops working, and snow stops entering the snow collecting box 34 from the snow conveying pipe 31. In addition, in order to facilitate water collection, a water pipe 36 is connected to the snow collecting box 34, and a faucet 37 is provided at the outer end of the water pipe 36. In addition, a filtering device can be connected to the water pipe 36 to filter the water in the snow collecting box 34, thereby improving the water quality and ensuring healthy drinking water.

[0059] In one embodiment of the present application, Figure 7As shown, the double spiral snow removal blade 214 includes a large spiral blade 2141, a spiral rod 2142 and a small spiral blade 2143. The outer diameter of the large spiral blade 2141 is larger than the outer diameter of the small spiral blade 2143. The large spiral blade 2141 and the small spiral blade 2143 are arranged on the outer periphery of the spiral rod 2142. The outer periphery of the large spiral blade 2141 is provided with ice-breaking saw teeth 2144, which can break the ice on the road surface to achieve the deicing effect. The spiral directions of the large spiral blade 2141 and the small spiral blade 2143 are opposite, that is, the snow can be discharged from the snow discharge ports on both sides of the housing 211, and part of the snow can be rolled into the snow delivery pipe 31. In addition, the front snow removal drive component includes a front snow removal motor 212 and a bevel gear set 213. The front snow removal motor 212 is fixed on the outer shell 211. The double-helix snow removal blade 214 includes a left and right section structure, and the two sections are connected to the rotating shaft of the front snow removal motor 212 through the bevel gear set 213.

[0060] In one embodiment of the present application, Figure 8 As shown, the snow removal system 2 also includes a rear snow removal device 22 located at the rear of the vehicle body, wherein multiple groups of rear snow removal devices 22 arranged side by side can be arranged at the rear of the vehicle body, and the rear snow removal device 22 can be connected through a buckle 1121 arranged at the rear end of the bottom of the chassis 112. The rear snow removal device 22 includes a rear snow removal drive component, a snow rolling brush 223, a wheel frame 225 and a tire 226. One end of the snow rolling brush 223 is connected to the rear snow removal drive component, and the other end is rotatably connected to the wheel frame 225, for example, through a bearing 224. The tire 226 is rotatably connected to the wheel frame 225, and the rotation axis of the snow rolling brush 223 is perpendicular to the rotation axis of the tire 226. The rear snow removal drive component includes a rear snow removal motor 221, which is installed at the rear end of the vehicle body, and the output shaft of the rear snow removal motor 221 is connected to a universal joint 222, and the other end of the universal joint 222 is connected to the snow rolling brush 223. The rear snow removal driving component can transmit power to the universal joint 222 to rotate, and the universal joint 222 then transmits power to the snow rolling brush 223 to rotate, thereby realizing the rear snow removal function. The tire 226 is rotatably connected to the snow rolling brush 223 through the wheel frame 225, which can ensure the safe operation of the rear snow removal device 22.

[0061] In some embodiments of the present application, Figure 2 As shown, the multifunctional snow removal vehicle also includes a material storage system 4, an auxiliary identification system 5, a central control system 6, and an energy supply system 7.

[0062] The material storage system 4 is located in the vehicle body, such as Fig.12As shown, the material storage system 4 includes a box body, and a box door 41 is provided on one side of the box body. The box door 41 includes a left door 411 and a right door 412. The left door 411 and the right door 412 are provided with a password lock 42, and the box door 41 needs to be opened by the password lock 42.

[0063] The auxiliary recognition system 5 includes a laser radar 51 and a camera 52 located on the top of the vehicle body and a millimeter wave radar 53 located under the chassis 112. Figure 1 , Figure 2 and Fig.13 as well as Fig.14 As shown, the external environment can be obtained by rotating the camera 52, but the camera 52 is easily affected by external factors such as backlight and weather. The laser radar 51 uses reflected light to rotate and scan, and the three-dimensional state of the outside world can be obtained. Therefore, through the joint use of the camera 52 and the laser radar 51, it is possible to accurately detect the external environment in the severe weather environment of severe cold and snowstorms in the border area. Four millimeter wave radars 53 can be set under the chassis 112 to determine the distance of the obstacle by using the time difference of the reflected wave of the obstacle. At the same time, the millimeter wave radar 53 has strong penetration, which makes up for the problem of reduced accuracy of the laser radar 51 and the camera 52 on snowy days, and further improves the recognition performance of the outside world.

[0064] The central control system 6 is respectively connected to the traveling system 1, the snow removal system 2, the snow collection and heating system 3 and the auxiliary identification system 5. The central control system 61 is responsible for collecting data and sending instructions in the snow removal vehicle.

[0065] First, when the front snow removal device 21 fails to clean up the remaining snow, the central control system 61 determines the position of the remaining snow through detection and turns on the snow rolling brush 223 at the corresponding position. When the rear end of the snow removal vehicle reaches the position of the remaining snow, the snow rolling brush 223 sweeps away the remaining snow.

[0066] Secondly, when the snow water in the snow collecting box 34 reaches the limit, the data collected by the water level sensor is sent to the central control system 61, and then the central control system 61 sends an instruction to stop the snow transport work of the snow transport pipeline 31.

[0067] Third, when it is detected that the track 111 has fallen into a pit, a command is sent to the central control system 61, and then the central control system 61 sends a command to the hydraulic valve 122 at the corresponding position to open it. After the hydraulic rod 121 is extended a certain distance, the central control system 61 also sends a command to close the hydraulic valve 122.

[0068] Fourthly, when the auxiliary recognition system 5 detects that there are people around, it sends data to the central control system 61, and then the central control system 61 sends a command to the light strip installed on the vehicle body to turn it on to warn the people around.

[0069] The energy supply system 7 includes a battery 71 and a solar heating panel 72 located on the top of the vehicle body. Figure 15 to Figure 17 As shown, the endurance of the snowplow can be improved and energy cleanliness can be achieved through the solar heating panel 72. The solar heating panel 72 includes a cross-arranged solar panel 721 and a heat panel 722. The heat panel 722 can heat the snow on the top of the vehicle body. The solar panel 721 is connected to the battery 71. The solar panel 721 can convert solar energy into electrical energy and store it in the battery 71. The battery 71 can provide electrical energy for various motors, snow collection and heating system 3, travel system 1 and other systems and devices that require electricity on the snowplow. In order to speed up the removal of snow water on the top of the vehicle body and prevent water accumulation on the top, the solar heating panel 72 is tilted on the top of the vehicle body. The solar heating panel 72 is divided into four parts, one for each front and rear, and two for each left and right between the front and rear. The heat panel 722 is provided with a drainage groove 723, which can further promote the rapid outflow of snow water.

[0070] In summary, the working principle of the multifunctional snow removal vehicle provided in the embodiment of the present application is as follows, please refer to Fig.18 :

[0071] At the beginning, the camera 52 starts detecting. If it detects that there are people around, the light strip flashes to warn; if no people are detected around, the light strip remains off and the camera 52 continues detecting.

[0072] The travel system 1 is started, the track 111 starts running, and the snowplow moves forward. At this time, the front snow removal device 21 starts working to clear the snow in the direction of travel. If an irregular road surface is encountered, the front snow removal device 21 cannot remove all the snow on the road. After detecting and determining the position of the remaining snow, the position of the remaining snow can be detected by the millimeter-wave radar 53 under the chassis, and the snow rolling brush 223 at the rear close to the position of the remaining snow is started to sweep away the remaining snow; if no remaining snow is detected, the rear snow rolling brush 223 remains in the closed state.

[0073] The ice and snow mixture crushed by the front snow removal device 21 will enter the snow collecting box 34 through the snow conveying pipe 31, and then be melted and heated by the heater 33, and the final snow water can be used by people. In order to prevent the influence caused by too much water in the snow collecting box 34, a sensor for detecting the water level is placed in the snow collecting box 34. If the water reaches the limit position, the conveying spiral piece 312 in the snow conveying pipe 31 stops working, and snow can no longer enter the snow collecting box 34 from the snow conveying pipe 31; if the water does not reach the limit position, the conveying spiral piece 312 keeps normal operation.

[0074] Since the device is used on rough roads, during the travel process, the sensor collects and transmits data in real time. When the track 111 falls into a pit, the hydraulic rod 121 at a nearby position extends a certain distance, and then determines whether the pit has been passed through the detection data. If the pit has been passed through, the hydraulic rod 121 is closed; if the pit has not been passed through, the hydraulic rod 121 continues to extend, and then the data is detected again to determine whether the pit has been passed through, until the pit has been passed through, and the hydraulic rod 121 is closed.

[0075] Specifically, Fig.19 As shown, when it is detected that the track 111 has sunk into a pit, the hydraulic valve 122 near the sunken position opens, thereby connecting the hydraulic valve 122 and the hydraulic rod 121, and the hydraulic oil enters the hydraulic rod 121. The hydraulic rod 121 extends a certain distance, and the hydraulic valve 122 is closed. The distance between the chassis 112 and the ground is detected. If it reaches the preset value, the self-rescue is successful; if it does not reach the preset value, the hydraulic valve 122 is opened again, and the process is repeated until the self-rescue is successful.

[0076] Specifically, Fig. 20 As shown, after the snow is sent into the snow collecting box 34, the heater 33 starts to work, melting and heating the snow water. The heated snow water passes through the water pipe 36 and can be used by turning on the faucet 37. If the water in the snow collecting box 34 reaches the limit position, the conveying spiral blade 312 in the snow conveying pipeline 31 stops working, and the snow can no longer enter the snow collecting box 34 from the snow conveying pipeline 31; if the water does not reach the limit position, the snow conveying pipeline 31 keeps operating normally.
