Description

Technical Field

[0001] The utility model relates to the technical field of snow removal, in particular to a highway snow removal machine. Background Art

[0002] With global climate change, the amount and frequency of snowfall in winter are increasing in some areas. As the main transportation infrastructure, the smoothness of highways is directly related to people's travel safety and the normal operation of the economy. Therefore, how to efficiently and quickly remove snow from highways has become an important issue in winter traffic management. Highway snowplows can be divided into many types according to different working principles and scopes of application. For example, plowboard snowplows are suitable for snow with a small thickness. The plowboard in front of the locomotive is driven by the locomotive to push the snow to the roadside; spiral snowplows are suitable for snow thickness exceeding 20 cm. Special spiral cutters are installed inside to effectively remove thick snow layers; snowplows are used to remove snow layers adhering to the road surface to achieve refined snow removal operations.

[0003] For example, a Chinese utility model patent (CN211973333U) discloses a highway snowplow, which solves the following problems: existing electric snowplows mostly use a snow-throwing operation method, using gears to break up and roll up the snow, and then a high-power blower blows it to both sides. During the removal process, the snow will be splashed everywhere, and the splashed snow must be cleaned, increasing the workload.

[0004] The device includes a snowplow body, a cab, a snow removal component, a snow melting component and a drainage component. The cab is arranged on the snowplow body, a driving wheel is arranged at the lower end of the snowplow body, the snow removal component is arranged at the front end of the snowplow body, the drainage component is arranged at the rear end of the snowplow body, and the snow melting component is arranged in the snowplow body and between the snow removal component and the drainage component. The utility model relates to a highway facility, specifically providing a highway snowplow that integrates a snow removal component, a snow melting component and a drainage component. The device can directly melt the removed snow in the snowplow body and use it to irrigate the green belt without the need for secondary snow transportation, thereby improving work efficiency and saving labor; at the same time, the ice-breaking knife and the snow shovel are matched to achieve the removal of frozen snow on the ground.

[0005] When using the above technology, it was found that the following technical problems exist in the prior art: the ice-breaking structure of the device can only rotate in one direction.

For this reason, we designed a highway snowplow to provide another technical solution to the above technical problems. Utility Model Content

When encountering particularly hard or unevenly thick ice, the two-way rotation can more effectively crush the ice layer, thereby improving the working efficiency of the snowplow.

[0051] The use process of a highway snowplow provided by the utility model is as follows: the user pushes the device to a place where snow needs to be cleared, the user energizes the hydraulic cylinder 2 to propel it, the output end of the hydraulic cylinder 2 drives the crushing roller 21 to rise and fall, and then the crushing roller 21 appears on the ice layer at the bottom of the snow, the user energizes the third motor 24 to rotate, the output end of the third motor 24 drives the worm 25 to rotate, because the bottom of the worm 25 is meshed and connected with a worm wheel 26, the rotation of the worm 25 drives the worm wheel 26 to rotate, and the rotation of the worm wheel 26 drives the rotating rod 27 and the cam 28 to rotate, so that the cam 28 is disengaged from the brake disc The user turns on the motor 15 to rotate, and the output end of the motor 15 drives the first bevel gear 16 to rotate. Since the second bevel gear 17 and the third bevel gear 18 are respectively meshed and connected on both sides of the first bevel gear 16, the rotation of the first bevel gear 16 drives the second bevel gear 17 and the third bevel gear 18 to rotate in the opposite direction, thereby driving the first rotating sleeve 19 and the second rotating sleeve 20 to rotate in the opposite direction. Since the outer sides of the first rotating sleeve 19 and the second rotating sleeve 20 are fixed with crushing rollers 21, the two crushing rollers 21 rotate in the opposite direction, thereby enabling the two crushing rollers 21 to efficiently perform ice breaking operations, thereby The operation of the snowplow is made simpler and more flexible. The driver can quickly adjust the rotation direction and angle of the ice-breaking structure according to actual needs to achieve efficient and accurate ice and snow removal. When position adjustment is required, the user energizes the first motor 8 to rotate, and the output end of the first motor 8 drives the first screw 7 to rotate. Since the outer side of the first screw 7 is threadedly connected with the moving block 9, the rotation of the first screw 7 drives the moving block 9 to slide at both ends of the bottom of the moving plate 4. The user energizes the second motor 12 to rotate, and the output end of the second motor 12 drives the second screw 13 to rotate. Since the outer side of the second screw 13 is also connected to the moving block 9, the rotation of the first screw 7 drives the moving block 9 to slide at both ends of the bottom of the moving plate 4. The moving block 9 is threadedly connected, so that the rotation of the second screw 13 drives the moving block 9 to slide on both sides of the bottom of the moving plate 4, so that the two crushing rollers 21 at the bottom can accurately adjust the position. After the ice layer is crushed, the user energizes the snow suction pump 31, and the input end of the snow suction pump 31 sucks the ice and snow into the snow suction pump 31 through the suction pipe 32, and fills it into the collection bucket 29 through the feed pipe 30 to complete the ice and snow collection.
