Description

Technical Field

[0001] The invention relates to a snow thrower and belongs to the technical field of snow throwers. Background Art

[0002] A snow thrower is a device used to remove snow. It is usually used for large-scale snow removal operations, especially in highways, airports, industrial parks and city streets. It can efficiently clear a large amount of snow. It uses a mechanical device to shovel snow from the ground and blow it to a place far away from the cleaning area through wind power.

[0003] However, in windy weather, the direction and strength of the wind may significantly affect the working effect of the snow thrower. Strong winds may not only blow the cleared snow back to the cleared area, affecting the working efficiency, but also blow the snow to the surrounding areas or passers-by, causing the cleaning work to be repeated or even unable to completely remove the snow, increasing potential safety risks.

[0004] In windy weather, the direction and strength of the wind will significantly affect the working effect of the snow thrower, especially the wind force of the snow thrower may interfere with the natural wind force, resulting in unstable cleaning effect. Strong winds will not only blow the snow that has been cleaned back to the cleaned area, affecting the work efficiency, but may also blow the snow to the surrounding areas or passers-by, causing repeated and incomplete cleaning work, increasing potential dangers. Especially after alternating rain and snow, the snow is often mixed with rainwater to form slippery and icy roads or icy snow. This mixture of ice and snow may be blown away or moved violently under the interference of strong winds. If it is accidentally blown onto passers-by, it is easy to cause safety hazards such as falls or injuries.

[0005] Therefore, the purpose of this study is to design a snow thrower that can be used in windy weather and can be adaptively adjusted according to wind strength and direction. Summary of the invention

The first conductive ring is electrically connected to the control module, and the heating plate is electrically connected to the second conductive ring through a power line inside the rotating shaft.

[0012] As a further improvement, a plurality of groups of teeth are provided on the first blade and the second blade, a connecting portion is provided between two of the teeth, and the thickness of the heating plate corresponding to the teeth is greater than the thickness at the connecting portion.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] Reference Figure 1-6 As shown, a snow thrower comprises: A main support 1, a spiral conveying auger installed below the main support 1, and a first driving component that drives the spiral conveying auger to rotate; A snow throwing drum 2 disposed on one side of the middle of the spiral conveying auger, and a second driving component driving the snow throwing drum 2 to rotate; A third driving assembly is provided for rotating a guide cylinder 3 mounted on the main support 1 and driving the guide cylinder 3 to rotate, wherein an input port below the guide cylinder 3 is connected to an output end of the snow throwing drum 2; Rotate the guide cylinder 31 installed above the guide cylinder 3, and drive the fourth driving component for adjusting the angle of the output port above the guide cylinder 31; A pedestrian monitoring module 5 disposed above the main support 1 and a wind monitoring module 4 disposed above the main support 1; It also includes a control module 6 and a simulation module 7, wherein the control module 6 is electrically connected to the pedestrian monitoring module 5, the wind monitoring module 4, the simulation module 7, the first drive component, the second drive component, the third drive component, and the fourth drive component; Controlling the first driving assembly to drive the spiral conveying auger to convey ice and snow toward the snow throwing drum 2 through the control module 6; The control module 6 controls the second driving assembly to drive the snow throwing drum 2 to throw ice and snow toward the guide cylinder 31; The pedestrian monitoring module 5 monitors the dynamics of pedestrians in real time, and the wind monitoring module 4 monitors the size and direction of wind in real time. The simulation module 7 cooperates with the pedestrian monitoring module 5 to preset the dynamic path of pedestrians, and cooperates with the wind monitoring module 4 to preset the falling point of ice and snow output by the guide cylinder 31; The control module 6 cooperates with the third drive assembly to control the guide cylinder 3 to rotate forward / reverse around the central axis and adjust the output direction of the guide cylinder 31. The control module 6 cooperates with the fourth drive assembly to drive the guide cylinder 31 to rotate around the connection of the guide cylinder 31 to adjust the output angle.

[0033] By monitoring the size and direction of wind in real time, the snow thrower can be adjusted according to the current wind conditions. Prevent the wind from blowing the thrown snow back into the cleaned area, reducing repeated work and incomplete cleaning. By monitoring the location and movement of pedestrians in real time, ensure that the snow thrower will not blow snow onto pedestrians during operation.

[0034] The direction and angle of the guide cylinder 31 are adaptively adjusted. The output direction of the guide cylinder 31 is adjusted by controlling the guide cylinder 3 to rotate forward or reverse around the central axis. According to the wind force and pedestrian dynamics, the output angle is adjusted by driving the guide cylinder 31 to rotate around the connection with the guide cylinder 3. The direction and angle of the guide cylinder 31 are adjusted in real time to ensure that the snow can accurately fall on the predetermined area and reduce the impact on the surrounding environment.

[0035] When in use, after the snow thrower is started, the wind monitoring module 4 and the pedestrian monitoring module 5 begin to monitor the environment in real time. The wind monitoring module 4 detects the current wind force and direction, and transmits the data to the control module 6. The pedestrian monitoring module 5 detects the position and dynamics of pedestrians, and transmits the data to the control module 6.

[0036] The simulation module 7 presets the dynamic path of pedestrians and the snowfall point under wind interference according to the data of the wind monitoring module 4 and the pedestrian monitoring module 5 .

[0037] The control module 6 adjusts the direction and angle of the guide cylinder 31 through the third drive assembly and the fourth drive assembly according to the preset path and landing point to ensure that the thrown snow can accurately fall in the predetermined area to avoid interfering with pedestrians and cleared areas.

[0038] Continuous monitoring and adjustment: the wind monitoring module 4 and the pedestrian monitoring module 5 continuously monitor environmental changes, and the control module 6 makes dynamic adjustments based on real-time data to ensure that the snow thrower is always in the best working condition.

[0039] Compared with the prior art, the operating efficiency is improved, and repeated work is reduced. By adaptively adjusting the direction and angle of the guide cylinder 31, the wind can be effectively prevented from blowing the snow back to the cleaned area, reducing repeated cleaning work and improving the overall operating efficiency.

[0040] Optimized snow throwing paths, preset snow falling points and dynamic paths of pedestrians can ensure that the snow thrower can still work efficiently in complex environments.

[0041] To enhance safety and prevent pedestrian injuries, the pedestrian monitoring module 5 can detect the position and dynamics of pedestrians in real time, ensuring that the snow thrower will not blow snow onto pedestrians, reducing safety hazards.

[0042] Reduce operational risks. In strong wind weather, the machine can automatically adjust working parameters to reduce the operational risks faced by operators due to wind influence.

[0043] The automatic adjustment function reduces the need for the operator to frequently manually adjust the direction and angle of the guide cylinder 31, thereby reducing the complexity of operation and labor intensity. The snow thrower has strong applicability and can adapt to a variety of weather conditions. Whether it is sunny, breezy or windy, the snow thrower can maintain efficient and safe operation through automatic adjustment.

[0044] Through the above-mentioned intelligent and adaptive adjustment functions, the operating efficiency and safety of the snow thrower in windy weather can be significantly improved.

[0045] The main support 1 includes a bucket 11 surrounding the spiral conveying auger, one side of the bucket 11 is an open portion 111, and the other side of the bucket 11 is welded and fixed with a mounting frame 12, which is arranged at a high point on the side of the bucket 11 through the pedestrian monitoring module.

[0046] The open portion 111 is a snow inlet in the direction of travel of the snow thrower.

[0047] The first driving assembly includes a first motor 13, and the first motor 13 is electrically connected to the control module 6; The spiral conveying auger includes a rotating shaft 14 rotatably installed at the output end of a first motor 13, and a group of spiral blades 15 welded on the rotating shaft 14. The two spiral blades 15 are arranged in opposite directions. The rotating shaft 14 is driven by the first motor 13 to drive the two spiral blades 15 to rotate, thereby conveying road ice and snow toward the central area.

[0048] The reverse setting of the spiral blades 15 is designed for bidirectional transportation. The two reversely set spiral blades 15 can transport ice and snow to the central area respectively, forming a symmetrical propulsion force, which helps to quickly gather ice and snow and reduce the lateral deviation of the machine. The reversely set spiral blades 15 can distribute the propulsion force more evenly, ensuring that the ice and snow are efficiently sent to the snow throwing drum 2, thereby improving the working efficiency of the entire snow thrower. The symmetrical propulsion force can reduce the lateral resistance of the machine during operation, making the machine run more smoothly and reducing energy consumption.

[0049] The spiral angle of the spiral twisted blade 15 is usually set between 20° and 30° to ensure that the ice and snow can be smoothly pushed forward under the action of the twisted blade.

[0050] The helical angles of the reversely arranged spiral twisted blades 15 can be the same or slightly different to adapt to different road conditions and cleaning requirements. Generally, selecting the same helical angle (such as 25°) can simplify the design and manufacturing process while maintaining good working results.

[0051] The symmetrical arrangement of the reverse spiral blades 15, the two sets of spiral blades 15 should be symmetrically arranged along the rotating shaft 14, to ensure that they can generate symmetrical propulsion when rotating. The left-handed and right-handed spiral blades 15 are respectively installed on both sides of the rotating shaft 14. The left-handed spiral blades 15 transport the ice and snow to the right central area, and the right-handed spiral blades 15 transport the ice and snow to the left central area. In this way, it can be ensured that the ice and snow are concentrated in the central area, which is convenient for further processing by the snow throwing drum 2.

[0052] In practical applications, the helix angle of the spiral twisted blade 15 can be adjusted according to the specific road width and ice and snow density. For example, if the road is narrow or the ice and snow are thick, a larger helix angle (such as 30°) can be selected to increase the propulsion force; if the road is wide or the ice and snow are thin, a smaller helix angle (such as 20°) can be selected to reduce the propulsion force and energy consumption.

[0053] Through the control module 6 , the road conditions and the machine operation status can be monitored in real time, and the rotation speed and output torque of the first motor 13 can be dynamically adjusted, so as to optimize the propulsion effect of the spiral blade 15 .

[0054] The specific effect is that the two spiral blades 15 arranged in opposite directions can evenly transport ice and snow from both sides to the central area, forming a central collection belt, which is convenient for the snow throwing drum 2 to handle. The symmetrical propulsion force can reduce the lateral deviation of the machine during operation, making the machine run more smoothly.

[0055] The two-way collection design can significantly increase the collection speed of ice and snow and reduce the cleaning time. By centrally transporting ice and snow in the central area, the snow throwing drum 2 can process and throw ice and snow more efficiently, improving the overall cleaning effect. The symmetrical propulsion force can reduce the lateral resistance of the machine, thereby reducing energy consumption. The control module 6 can dynamically adjust the motor speed and output torque according to actual conditions, so that the machine can maintain the best working state under different conditions and further reduce energy consumption.

[0056] In addition, considering the heavy weight of wet snow and ice, strong winds may make these ice and snow masses more difficult to control, increasing the risk to equipment and operators. Therefore, when using a snow blower in strong winds and bad weather, special attention should be paid to the surrounding environment to avoid causing harm to others, and appropriate protective measures should be taken to ensure that the cleanup work is carried out safely.

[0057] After the alternation of rain and snow, the accumulated snow often mixes with rainwater to form slippery and icy roads or ice and snow. This mixture of ice and snow may be blown away or moved violently under the interference of strong winds. If it is blown to passers-by accidentally, it is easy to cause safety hazards such as falls or injuries.

[0058] Therefore, the spiral conveying auger also includes a set of fixed cylinders 16 installed on the side of the bucket 11, and a protective sleeve 17 sleeved on the outer annular surface of the fixed cylinder 16, and the protective sleeve 17 is rotatably connected to the fixed cylinder 16 through a bearing 18; The first motor 13 is fixedly installed inside the fixing tube 16 . The output shaft of the first motor 13 is fixedly connected to the protective sleeve 17 .

[0059] The spiral blade 15 includes a first blade 151, a second blade 152, and a heating plate 153 disposed between the first blade 151 and the second blade 152. The first blade 151 and the second blade 152 are seamlessly welded and fixed on the rotating shaft 14. The conductive component includes a first conductive ring 154 installed on the outer ring surface of the fixed tube 16 and a second conductive ring 155 embedded in the inner ring surface of the protective sleeve 17. The first conductive ring 154 is electrically connected to the control module 6, and the heating plate 153 is electrically connected to the second conductive ring 155 through a power line inside the rotating shaft 14.

[0060] The first conductive ring 154 and the second conductive ring 155 are not in direct contact with each other, and wireless power supply technology is used. That is, without any physical connection, the electric energy can be transmitted to the load without contact at a close distance. The first conductive ring 154 and the second conductive ring 155 can be made of highly conductive materials such as copper and carbon, and conduct electricity through electromagnetic induction coils.

[0061] It should be emphasized that the conductive wires disposed inside the rotating shaft 14 need to be insulated.

[0062] The fixing tube 16 and the protective sleeve 17 are provided firstly to protect the motor. The first motor 13 is installed inside the fixing tube 16, which can effectively protect the motor from the influence of the external environment, such as ice, snow, water, dust and the like.

[0063] The protective sleeve 17 is sleeved on the outer ring surface of the fixed cylinder 16 and is rotatably connected via the bearing 18 to ensure that the spiral strands 15 do not generate direct friction with the external environment during rotation, thereby reducing potential safety hazards.

[0064] The design of the fixing tube 16 and the protective sleeve 17 makes the maintenance of the motor and the spiral strand 15 more convenient, and they can be quickly disassembled and replaced.

[0065] This arrangement can effectively isolate the motor from the external environment by the fixing cylinder 16 and the protective sleeve 17, thereby extending the service life of the motor. The bearing 18 connection can reduce the friction between the protective sleeve 17 and the fixing cylinder 16, reduce mechanical wear, and improve the durability of the overall system. The design of the protective sleeve 17 increases the safety of operation and prevents the operator from being injured during operation of the machine.

[0066] The structural setting of the spiral blade 15 is to enhance the ice-breaking ability. The spiral blade 15 includes a first blade 151 and a second blade 152. The design of these two blades can effectively break ice and snow and prevent large pieces of ice and snow from getting stuck in the machine.

[0067] In addition, a heating sheet 153 is provided between the first blade 151 and the second blade 152, which can effectively prevent ice and snow from condensing on the blade, thereby ensuring efficient operation of the blade.

[0068] By adopting seamless welding, the first blade 151 and the second blade 152 and the rotating shaft 14 are fixed by seamless welding, which ensures the strength and stability of the structure and reduces the failure caused by poor welding.

[0069] The design of the first conductive ring 154 and the second conductive ring 155 ensures that the power transmission of the heating plate 153 is stable and reliable, and the power supply is not affected even when the protective sleeve 17 rotates. The first conductive ring 154 is electrically connected to the control module 6, and the heating plate 153 is electrically connected to the second conductive ring 155 through the power line inside the rotating shaft 14, achieving dual protection of power supply and control signal.

[0070] Through the above arrangement, when the spiral twist blade 15 breaks and twists the ice and snow on the road surface, the first blade 151 and the second blade 152 can be kept in a heated state under the action of the heating plate 153 .

[0071] This arrangement can improve work efficiency. On the one hand, the design of the double-layer blade can efficiently break ice and snow, speeding up the collection and transportation of ice and snow. On the other hand, the heating sheet 153 can prevent ice and snow from condensing on the blade, ensuring the continuous and efficient operation of the blade.

[0072] The running stability is enhanced, and the spiral blades 15 arranged in opposite directions generate symmetrical propulsion force, which reduces the lateral deviation of the machine and makes the running more stable.

[0073] The design of the protective sleeve 17 and the fixing tube 16 increases the safety of operation and prevents the machine from causing harm to the operator and the surrounding environment during operation.

[0074] A plurality of groups of teeth 156 are disposed on the first blade 151 and the second blade 152 . A connecting portion 157 is disposed between two of the teeth 156 . The thickness of the heating plate 153 corresponding to the teeth 156 is greater than the thickness at the connecting portion 157 .

[0075] The first motor 13 is fixedly mounted on the inner side of the bucket 11 , and can be mounted specifically by bolts.

[0076] The snow throwing drum 2 sucks the snow into the machine through the rotating propeller (or drum), and then throws the snow to one side or far away through the ejection tube to achieve the purpose of clearing the snow. The snow throwing drum 2 mainly has the following types: The single-stage snow-throwing drum 2 uses a rotating propeller to directly suck in and throw out the snow. It is suitable for clearing light to moderate snow accumulation, is easy to operate, and is lightweight, making it suitable for home use.

[0077] The Dual-Stage Snow Drum 2 consists of two main parts - a rotating paddle and a snow thrower. First, the rotating paddle draws the snow into the machine, and then the second stage snow thrower powerfully throws the snow a greater distance. The Dual-Stage Snow Drum 2 is suitable for clearing heavy or wet snow, and it can throw the snow farther and work more efficiently, but it is more complex, bulky and expensive than a single-stage model.

[0078] The three-stage snow-throwing drum 2 has an additional acceleration stage in addition to the two stages of the two-stage snow-throwing drum 2, which can throw the snow further and is suitable for snow removal under extreme conditions.

[0079] Snow thrower drums 2 are widely used, especially in areas with frequent snowfall. They are very practical equipment for households, commercial places, municipalities, etc. When choosing a snow thrower drum 2, it is necessary to determine the most suitable type according to actual usage requirements (such as the amount and type of snow accumulation, the area to be cleared, etc.). At the same time, correct operation and maintenance of the snow thrower drum 2 are also very important to ensure its safety and extend its service life.

[0080] In this embodiment, a single-click snow-throwing drum wheel 2 is adopted.

[0081] The third driving assembly includes a second motor 32 fixedly mounted on the main bracket 1, a gear 33 is mounted on the output end of the second motor 32, a gear ring 34 is arranged on the outer ring surface of the guide tube 3, the gear 33 and the gear ring 34 are connected by a chain belt 37 with tooth holes, the gear 33 is driven to rotate forward / reverse by the second motor 32, and the guide tube 3 is controlled to rotate in coordination with the chain belt 37 and the gear ring 34.

[0082] The fourth driving assembly includes a telescopic hydraulic cylinder 35 rotatably mounted on the outside of the guide cylinder 31, and the protruding end of the telescopic hydraulic cylinder 35 is rotatably mounted on the outside of the guide cylinder 31. The telescopic hydraulic cylinder 35 is connected to a hydraulic pump 36 fixedly mounted on the main bracket 1, and the hydraulic pump 36 is electrically connected to the control module 6.

[0083] The control module 6 controls the hydraulic pump 36 , and cooperates with the telescopic hydraulic cylinder 35 to control the guide tube 31 to rotate and adjust the angle.

[0085] Among them, the wind force and direction meter is a device used to detect wind speed and direction in real time. The use of wind force and direction meter can significantly improve the intelligence level and safety of the system. Usually mechanical or electronic sensors are used.

[0086] Mechanical type, common ones are cup type and propeller type. Electronic type, common ones are ultrasonic type and pressure type.

[0087] Wind direction sensor, used to measure wind direction, usually adopts wind vane or electronic sensor.

[0088] The wind vane type indicates the wind direction by the deflection of the wind vane, and the direction identification element is set at the bottom to be electrically connected to the control module 6, so as to accurately identify the wind direction. The common electronic types are ultrasonic type and magnetic resistance type.

[0089] The data processing unit processes the collected wind speed and direction data, converts them into digital signals and transmits them to the control module 6. The communication interface is used to transmit the processed data to the control module 6 of the snow thrower. Common interfaces include wireless communication (such as Bluetooth, Wi-Fi) and wired communication (such as RS-485, CAN bus).

[0090] First, the number of pedestrians on both sides of the road is identified through the pedestrian monitoring module 5, and the pedestrian travel route is simulated in cooperation with the simulation module 7. The pedestrian travel speed is lower than the snow thrower travel speed.

[0091] When there is no wind, the control module 6 cooperates with the third driving assembly to control the guide cylinder 3 to rotate, and the output end of the guide cylinder 31 faces the side with fewer pedestrians; When the wind direction is opposite to the direction in which the guide tube 31 throws snow, when the wind speed is at level 0-3, the guide tube 3 throws snow at a preset angle, wherein the preset working angle of the guide tube 3 is 60°.

[0092] The guide cylinder 31 is rotated downward around the connection of the guide cylinder 31 to adjust the angle range of 3°-27°.

[0093] Among them, when the snow throwing landing point preset by the simulation module 7 intersects with the dynamic path of the pedestrian, the control module 6 cooperates with the fourth drive component to perform an adjustment to drive the guide cylinder 31 to rotate downward around the connection of the guide cylinder 31 by 3-5°. If the preset landing point after adjustment still intersects with the dynamic path of the pedestrian, during the second cycle adjustment, 1° is added to the first adjustment angle. If the first downward adjustment angle is 5°, that is, the second downward adjustment angle is 6°, after the second adjustment, the difference with the initial working angle is 11°.

[0094] When the wind speed is at level 4-5, in the previous adjustment process, when the preset landing point still intersects with the pedestrian dynamic path after 4 cycles, that is, in this section of the pedestrian path, the control module 6 is used to control the snow throwing drum 2 to reduce the throwing power by 10%-15%, and the throwing power is restored when passing through this section of the pedestrian path. In this embodiment, the snow throwing drum 2 reduces the rotation speed by 10%.

[0095] The snow throwing drum speed adjustment range is 10%-30%.

[0096] When the wind speed is at level 6-7, the control module 6 cooperates with the third driving assembly to control the guide cylinder 3 to rotate, so that the throwing direction of the guide cylinder 31 is in the downwind direction.

[0097] When the snow throwing landing point preset by the simulation module 7 intersects with the dynamic path of the pedestrian, the control module 6 cooperates with the fourth drive component to perform an adjustment to drive the guide cylinder 31 to rotate downward around the connection of the guide cylinder 31 by 3-5°. If the preset landing point after adjustment still intersects with the dynamic path of the pedestrian, during the second cycle adjustment, 1° is added to the first adjustment angle. If the first downward adjustment angle is 5°, that is, the second downward adjustment angle is 6°, after the second adjustment, the difference with the initial working angle is 11°.

[0098] In the previous adjustment process, when the preset landing point still intersects with the pedestrian dynamic path after four cycles, that is, in this section of the pedestrian path, the control module 6 controls the snow throwing drum 2 to reduce the throwing power by 15%-30%, and restores the throwing power when passing through this section of the pedestrian path. In this embodiment, the snow throwing drum 2 reduces the speed by 20%.

[0099] When the above adjustments are unavoidable, the power of the snow-throwing drum 2 is turned off in the pedestrian path.

[0100] By installing two sets of wind speed and direction measuring instruments on both sides above the bucket 11, changes in wind force and wind direction can be detected in real time.

[0101] The wind force detection result is electrically connected to the control module 6, and the snow throwing direction and angle of the guide cylinder 31 can be dynamically adjusted to ensure the best snow throwing effect.
