Description

Technical Field

[0001] This utility model relates to the field of snow removal equipment technology, specifically to a small snow removal robot. Background Technology

[0002] Winter snowfall causes significant inconvenience to people's travel, and timely snow removal is a crucial measure to ensure traffic safety. Currently, large snow removal equipment (such as snowplows and spreaders) is mainly used on urban main roads and highways, but its large size and high cost make it unsuitable for narrow areas such as sidewalks, community gardens, and courtyards. Snow removal in these areas relies primarily on manual labor, which is inefficient and labor-intensive. Therefore, some smaller snow removal devices have emerged in the existing technology. For example, Chinese utility model patent CN211815953U discloses a small household snowplow, including a frame body with a snowplow blade fixedly connected to the front end and wheels movably fitted to the bottom of the rear end. This small household snowplow not only completely removes and cleans the snow but also reduces resistance, making it easier and faster to operate and remove outdoor snow.

[0003] However, the existing snow removal equipment has limited functionality, lacks intelligent control, cannot achieve continuous operation for extended periods, and has a narrow range of applications. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a small snow removal robot that enables flexible switching between two snow removal modes through connecting components and a drive unit; combines automation and manual supervision through detection components and remote control; and ensures an ultra-long operating range and good snow removal effect through the combination of battery and generator.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a small snow removal robot, including a frame, a walking component disposed on the bottom side of the frame, a detection component disposed on the top side of the frame, and a connecting component disposed on the front side of the frame. A snowplow and a snow-throwing component are detachably connected to the connecting component. A drive unit for driving the connecting component is disposed on the frame. A controller connected to the drive unit is disposed inside the frame. The controller is connected to a rechargeable battery. The walking component, the detection component, the snow-throwing component, and the drive unit are all electrically connected to the controller.

[0006] A generator is installed inside the vehicle frame. The generator is electrically connected to the rechargeable battery through the controller. The controller is equipped with a remote wireless communication module that connects to a mobile terminal.

[0007] The connecting assembly includes two support arms mounted on the frame, a first connecting rod rotatably mounted on the support arms, connecting arms rotatably mounted on both ends of the first connecting rod, and a second connecting rod connected to both ends of the connecting arms. The two ends of the second connecting rod are rotatably connected to the connecting arms. The drive unit is connected to the second connecting rod. The connecting arms are detachably connected to the snowplow and the snow-throwing assembly.

[0008] The drive unit includes a motor I with its housing hinged to the frame, a lead screw connected to the output shaft of the motor I, and an internal threaded sleeve on the side of the connecting rod II, with the lead screw threadedly connected to the internal threaded sleeve.

[0009] The walking assembly includes a driving track wheel and a driven track wheel that are rotatably mounted on both sides of the frame, a track plate sleeved on the outside of the driving track wheel and the driven track wheel, and a second motor connected to the driving track wheel on the frame. The second motor is electrically connected to the controller.

[0010] The detection component includes a support frame mounted on the top of the vehicle frame, a front camera and a rear camera mounted on the support frame, and a front searchlight and a rear searchlight mounted on the top side of the vehicle frame.

[0011] The snow-throwing assembly includes a snow-gathering trough detachably connected to the connecting arm, a snow-collecting cutter rotatably disposed within the snow-gathering trough, and a third motor connected to the snow-collecting cutter. The third motor is disposed on the outside of the snow-gathering trough and is detachably connected to the controller via a cable. A snow-collecting chamber is provided on the side of the snow-gathering trough, and a snow-throwing tube for throwing snow is provided on the side of the snow-collecting chamber. A conveying unit for conveying snow from the snow-gathering trough to the snow-throwing tube is provided inside the snow-collecting chamber.

[0012] The conveying unit includes a connecting plate coaxially connected to the motor and snow collecting blades arrayed on the connecting plate, with the snow collecting blades facing the snow collecting cutter.

[0013] The snow-collecting shovel includes a connecting shaft, spiral blades arrayed on the side of the connecting shaft, a worm wheel disposed on the side of the connecting shaft, and a worm meshing with the worm wheel. The worm is connected to the output shaft of the motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] With easily interchangeable snowplows and snow-throwing components, a single machine can perform both snow-pushing and snow-throwing operations, adapting to different snow conditions and operational needs. Equipped with front and rear cameras and a remote wireless communication module, operators can remotely monitor and control the machine via mobile terminals, resulting in a high degree of automation and reduced labor intensity. Utilizing a tracked walking mechanism, it features low ground pressure and high traction, providing excellent mobility and stability on snow-covered and slippery surfaces. Long-lasting and highly efficient, the built-in generator continuously charges the rechargeable battery, significantly extending continuous operating time, making it suitable for large-area snow removal tasks. Its rational structure and reliable performance are further enhanced by a four-bar linkage connecting component, a lead screw drive for the drive unit, and a snow-throwing component combining a worm gear and centrifugal blade design, resulting in a stable structure, high transmission efficiency, and excellent snow removal effect.

The worm 624 is connected to the output shaft of the motor 63.

[0035] The specific working process of this utility model:

[0036] The following five processes are the detailed workflow from initiation to completion of the snow removal task. Specifically:

[0037] First Process: Initiation and Task Planning

[0038] System startup and self-test: The user sends a startup command to the robot's remote wireless communication module via a mobile terminal (such as a mobile APP). After receiving the command, the controller wakes up the system and first performs a self-test on the rechargeable battery power, walking component 2, detection component 3, drive unit 7, and snow-throwing component 6, and then feeds back the status information to the mobile terminal.

[0039] Task setting and environmental scanning: The user sets the snow removal area boundary or selects the working mode (such as "full coverage cleaning" or "path cleaning") on the mobile terminal. The robot activates the detection component 3 on top, and the front camera 311 and rear camera 312 begin to collect high-definition video streams of the surrounding environment and transmit them back to the user terminal in real time, providing a first-person perspective view. At the same time, the front spotlight 32 and rear spotlight 33 automatically turn on when the light is insufficient, ensuring visibility at night or in inclement weather.

[0040] Path planning: The controller integrates camera visual information and preset tasks, and plans the optimal snow removal path through a built-in algorithm.

[0041] Second process: Movement and snow positioning

[0042] Autonomous movement: The controller sends commands to motor 24 of the walking component 2, driving the active track wheel 21 to rotate. Due to the use of track plates 23, the robot can obtain good traction and passability on complex road surfaces such as snow and ice, and move steadily along the planned path.

[0043] Snow detection and confirmation: During travel, the front camera 311 continuously scans the road ahead. When a snow-covered area is detected ahead, the controller can reduce the travel speed to prepare for snow removal operations.

[0044] The third step: Snow removal operations (snow shoveling and snow throwing)

[0045] Snowplow 5 operating modes:

[0046] When it is necessary to clear loose snow from flat surfaces (such as sidewalks and plazas), the robot uses snowplows 5. The controller starts motor 71 of drive unit 7, causing the output shaft of motor 71 to drive screw 72 to rotate. Since screw 72 is threadedly connected to the internal threaded sleeve 441 on connecting rod 44, the rotating screw 72 will push or pull connecting rod 44 to move. The movement of connecting rod 44 is transmitted through the linkage mechanism composed of connecting arm 43 and connecting rod 42, thereby affecting the angle and height of snowplow 5 connected to connecting arm 43, so that it cuts into the snow at the optimal angle of attack (usually an inclination angle).

[0047] Snow removal: The robot continues to move forward, with snowplow 5 scooping up and collecting the snow in front of it. Continuous propulsion pushes the snow forward to the designated area or one side of the path.

[0048] Snow Throwing Component 6 Operation Mode:

[0049] Mode switching: When encountering heavy snow or needing to throw snow a greater distance (such as beyond roadside green belts), after installing the snow-throwing component 6 onto the connecting arm 43, switch to snow-throwing mode via terminal command. The robot will then move to the designated position and adjust the connecting arm 43 via the drive unit 7 to lower the snow-throwing component 6 to the working position.

[0050] Snow collection and transport: The bottom of the snow collection trough 61 is brought into contact with the snow surface to collect the snow.

[0051] Crushing and Collection: The controller starts motor 3 63, which drives worm gear 624 to rotate. Worm gear 624 meshes with worm wheel 623 on snow collecting cutter 62, driving connecting shaft 621 and its spiral blades 622 to rotate at high speed. The rotating cutter crushes the snow and spins it into the snow collection chamber 611 inside the snow collection trough 61.

[0052] Snow Throwing: Motor 3 63 drives the snow collecting blades 652 to rotate synchronously at high speed via connecting plate 651. The snow collecting blades 652 form a centrifugal fan, which sucks in snow debris from the snow collecting chamber 611 at high speed; the sucked-in snow debris is violently thrown out in the direction of the snow throwing tube 64 under the action of centrifugal force. The user can control the direction and distance of snow throwing by manually adjusting the outlet orientation of the snow throwing tube 64.

[0053] Fourth process: Energy management, monitoring and anomaly handling

[0054] Continuous power supply: Throughout operation, the rechargeable battery provides power to all motors and controllers. To extend battery life, the built-in generator 8 can be driven by a combustion engine, automatically starting when the battery level drops below a threshold and charging the battery via the controller, enabling long-term uninterrupted operation.

[0055] Full monitoring: Users can always view the real-time images transmitted by the front and rear cameras 312 through their mobile terminals, monitor the robot's working status, the surrounding environment, and the snow removal effect, and can make manual interventions at any time.

[0056] Task Completion and Return: When the robot has completed snow removal in all planned areas or is about to run out of battery power, the controller will send a notification to the user. The user can then instruct the robot to return along the same route or proceed to a designated charging point; the robot will then automatically navigate back.

[0057] Fifth process: Maintenance and storage

[0058] Component Separation: After the task is completed, the user can detach the snowplow blade 5 or the snow-throwing assembly 6 from the connecting arm 43 for easy storage and maintenance. The cable between the motor 63 of the snow-throwing assembly 6 and the controller is also a detachable plug, further simplifying the disassembly process.

[0059] Cleaning and charging: After a simple cleaning of the robot, connect it to a power source to recharge the rechargeable battery and prepare it for the next task.

[0060] With its interchangeable snowplow blades 5 and snow-throwing assembly 6, a single machine can perform both snow-pushing and snow-throwing operations, adapting to different snow conditions and operational needs. Equipped with front and rear cameras 312 and a remote wireless communication module, operators can remotely monitor and control the machine via a mobile terminal, resulting in a high degree of automation and reduced labor intensity. Its tracked walking mechanism features low ground pressure and high traction, providing excellent mobility and stability on snow-covered and slippery surfaces. Long-lasting and highly efficient, the built-in generator 8 can charge the rechargeable battery in real time, significantly extending continuous operating time and making it suitable for large-area snow removal tasks. Its reasonable structure and reliable performance are further enhanced by the four-bar linkage 4, the lead screw drive 7, and the snow-throwing assembly 6's combination of a worm gear 623, a worm 624, and centrifugal blades, resulting in a stable structure, high transmission efficiency, and excellent snow removal effect.

[0061] The connection component 4 and the drive unit 7 enable flexible switching between two snow removal modes; the detection component 3 and remote control enable a combination of automation and manual supervision; and the combination of battery and generator 8 ensures an ultra-long operating range, enabling switching between multiple snow removal modes, remote monitoring, and long-endurance operation.

[0062] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
