A small snow removal vehicle based on automatic lifting of a rolling brush

Abstract

The present application relates to the field of rolling brush snow removal, and particularly relates to a small snow removal vehicle based on automatic lifting of a rolling brush, which comprises a snow isolation cover, motors arranged on the two side surfaces of the snow isolation cover, rotating cylinders fixedly arranged on the surfaces of the transmission shafts of the motors, notches arranged on the outer side surfaces of the snow isolation cover, swing arms movably sleeved in the notches, impact rods arranged at one end of the swing arms and located in the snow isolation cover, buffer wires fixedly connected to the other ends of the swing arms and located on the two side surfaces, and inner container rods arranged in the impact rods. When the screen bars impact on the surfaces of the impact rods, the screen bars directly impact on the surfaces of the impact blocks. The instantaneous extrusion force caused by the impact makes the impact blocks drive the sliding plates to move and extrude into the depths of the notches. The silicone soft blocks in the notches simply buffer the extrusion force from the outside, so that the silicone soft blocks preliminarily buffer the extrusion of the impact blocks before the buffer wires buffer the swing arms.

Description

Technical Field

[0001] This invention belongs to the field of roller brush snow removal technology, specifically a small snow removal vehicle based on automatic lifting of roller brushes. Background Technology

[0002] Winter service vehicles, also known as snowplows or snow removal machines, are used to clear snow and ice from main roads. Winter service vehicles typically use the chassis of automatic dump trucks as a base, with modifications to equip them with specialized snow removal equipment. Many organizations also use smaller vehicles to clear snow from sidewalks, side roads, and single-vehicle paths.

[0003] Currently, in snowy weather, if snow cannot be cleared from roads in time, it will affect the normal driving of vehicles. Furthermore, the continuous compaction of snow by vehicles will cause it to become increasingly compacted. If the contact force between the high-speed brush and the compacted snow is insufficient, the brush will be unable to effectively remove the snow clumps. Additionally, the compacted snow clumps will gradually stick together at low temperatures, making their surface very smooth. Therefore, it is crucial to clear the snow immediately after snowfall. However, snow in the south has high humidity, high water content, and high viscosity. This causes the resistance to the brush's agitation and throwing of thick, wet snow to increase exponentially. This not only significantly reduces the brush's rotation speed but also increases the amount of snow and water adhering to the brush tip, increasing the weight and affecting the brush's snow-clearing efficiency. It can also lead to the brush detaching and becoming damaged.

[0004] Therefore, the present invention provides a small snowplow based on automatic lifting of a roller brush. Summary of the Invention

[0008] Preferably, the inner wall of the snow cover is provided with a snow scraper, and the snow scraper is positioned on the outer surface of the rotating cylinder.

[0009] Preferably, a second limiting plate is provided at the opening edge of the slot, and the outer surface of the slide plate is movably sleeved on the outer surface of the second limiting plate.

[0010] Preferably, one end of the slide plate is fixedly connected to the outer surface of the silicone block, and both ends of the impact block are movably connected to the outer surface of the impact rod.

[0011] Preferably, the top surface of the snow cover is provided with multiple sets of hydraulic pumps, and the top surface of the hydraulic pumps is fixedly connected with a protective cover.

[0012] Preferably, the bottom surface of the protective cover is provided with a flow guide plate, one side surface of the flow guide plate is located at the bottom edge of the rotating cylinder, and the bottom surface of the protective cover is provided with a caster wheel located at the other edge.

[0013] Preferably, a splash guard is provided on the outer surface of the protective cover and at one edge of the universal wheel, a support frame is fixedly connected to the outer surface of the snow cover, and the outer surface of the motor is provided on the outer surface of the support frame.

[0014] Preferably, the protective cover has symmetrically fixedly connected limit rods on both sides, and the outer surface of the support frame is movably sleeved on the outer surface of the limit rods.

[0015] Preferably, a hydraulic actuator is provided on the top surface of the protective cover, and a small snowplow is provided on the outer surface of the hydraulic actuator and at one edge of the protective cover.

[0016] The beneficial effects of this invention are as follows: 1. The present invention describes a small snowplow based on automatic lifting of a roller brush. When the roller brush strikes a movable hard block with a spring, the impact rod swings to one side under the impact of the screen bar, thereby compressing the buffer wire. During this compression process, the original huge kinetic energy of the roller brush is not released on the contact surface, but is converted into the elastic potential energy of the buffer wire. Moreover, the compressed buffer wire stores the energy of the impact of the screen bar. The compression process of the buffer wire prolongs the contact and deceleration time between the screen bar and the impact rod. The compressed buffer wire expands under the reverse push of its own energy, driving the swing arm and the impact rod to reset. This allows the screen bar to repeatedly contact the impact rod. Under the swing and reset of the buffer wire, the impact rod can swing repeatedly, turning the original sharp and violent rigid impact into a relatively soft elastic collision. This greatly reduces the contact between the screen bar and the outside world while breaking ice on the surface, changing from rigid contact to flexible contact. 2. The small snowplow based on automatic lifting of roller brush described in this invention, when the screen bar hits the surface of the impact rod, the screen bar will directly collide with the surface of the impact block. The instantaneous extrusion force brought about by the impact will first cause the impact block to drive the sliding plate to move deeper into the slot. The silicone soft block inside the slot will provide simple buffering of the external extrusion force. Before the buffer wire buffers the swinging arm, the silicone soft block will provide preliminary buffering of the extrusion of the impact block, so as to avoid the screen bar from expanding and wearing when it comes into direct contact with the impact rod. 3. The present invention describes a small snowplow based on automatic lifting of a roller brush. A hydraulic pump pushes the snow cover, raising the roller brush on the outer surface of the rotating cylinder 10cm off the ground. A motor then rotates the cylinder, causing the roller brush to quickly clear snow from the ground. Since the rotating cylinder moves in the same direction as the snowplow, it pushes the snow towards the front of the vehicle. Heavier snow chunks and wet snow, after being lifted by the brush bristles, fall along a short parabolic trajectory due to gravity, landing directly on the roadside adjacent to the lane, forming a temporary snow strip. Most of the thrown snow initially impacts the bottom surface of the splash guard. The splash guard controls the throwing height of the snow, allowing it to settle quickly upon impact, preventing the spread of snow water mixed with mud and avoiding secondary pollution of the road surface and air.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 2 to 10As shown, an embodiment of the present invention discloses a small snowplow based on automatic lifting of a roller brush, including a snow cover 122 and a motor 125 disposed on both sides of the snow cover 122, and a rotating cylinder 126 fixedly mounted on the drive shaft surface of the motor 125. The outer surface of the snow cover 122 has multiple slots a1, and a swing arm a2 is movably sleeved inside the slots a1. One end of the swing arm a2, located inside the snow cover 122, is provided with an impact rod a6, and the other end of the swing arm a2, located on both sides, is fixedly connected with a buffer wire a5. The impact rod a6 is provided with... An inner rod a7 is provided, and a slot a8 is opened inside the inner rod a7. A silicone soft block a9 is provided inside the slot a8. Multiple sliding plates a11 are movably fitted inside the slot a8. An impact block a12 is fixedly connected to one end of the sliding plate a11. A second limiting plate a10 is provided at the edge of the opening of the slot a8. The outer surface of the sliding plate a11 is movably fitted onto the outer surface of the second limiting plate a10. One end of the sliding plate a11 is fixedly connected to the outer surface of the silicone soft block a9. The two ends of the impact block a12 are respectively movably overlapped on the outer surface of the impact rod a6.

[0022] When the roller brush strikes the spring-loaded movable block, the impact rod a6 swings to one side under the impact of the screen bar, thereby compressing the buffer wire a5. During this compression process, the roller brush's original huge kinetic energy is not released on the contact surface, but is converted into the elastic potential energy of the buffer wire a5. Moreover, the compressed buffer wire a5 stores the energy of the screen bar impact. The compression process of the buffer wire a5 prolongs the contact and deceleration time between the screen bar and the impact rod a6. The compressed buffer wire a5 expands under the reverse push of its own energy, driving the swing arm a2 and the impact rod a6 to reset, so that the subsequent screen bar can repeatedly contact the impact rod a6. Under the swing and reset of the buffer wire a5, the impact rod a6 can swing repeatedly, turning the originally sharp and violent rigid impact into a relatively soft elastic collision, greatly reducing the contact between the screen bar and the outside world while breaking the ice on the surface, changing from rigid contact to flexible contact. When the screen bar impacts the surface of the impact rod a6, the screen bar will directly collide with the surface of the impact block a12. The instantaneous squeezing force brought about by the impact will first cause the impact block a12 to drive the sliding plate a11 to squeeze and move deeper into the slot a8. The silicone soft block a9 inside the slot a8 will provide simple buffering of the external squeezing force. Before the buffer wire a5 buffers the swinging arm a2, the silicone soft block a9 will provide preliminary buffering of the squeezing of the impact block a12, so as to avoid the screen bar from expanding and wearing when it comes into direct contact with the impact rod a6.

[0023] like Figures 1 to 5As shown, the top surface of the snow cover 122 is provided with multiple sets of hydraulic pumps 121. The top surface of the hydraulic pumps 121 is fixedly connected to a protective cover 12. The bottom surface of the protective cover 12 is provided with a diversion plate 123. One side surface of the diversion plate 123 is located at the bottom edge of the rotating cylinder 126. The bottom surface of the protective cover 12 and the other side edge are provided with a caster wheel 129. The outer surface of the protective cover 12 and the edge of the caster wheel 129 are provided with a splash guard 128. The outer surface of the snow cover 122 is fixedly connected to a support frame 124. The outer surface of the motor 125 is located on the outer surface of the support frame 124. Limiting rods 127 are symmetrically fixedly connected to both sides of the protective cover 12. The outer surface of the support frame 124 is movably sleeved on the outer surface of the limiting rods 127. The top surface of the protective cover 12 is provided with a hydraulic actuator 111. The outer surface of the hydraulic actuator 111 and the edge of the protective cover 12 are provided with a small snowplow 11.

[0024] The small snowplow 11 moves the protective cover 12 to the top surface of the snow pile. At this time, the hydraulic actuator 111 rotates the protective cover 12 by 30°. Simultaneously, the hydraulic pump 121 pushes the snow barrier 122, causing the roller brush on the outer surface of the rotating cylinder 126 to be 10cm off the ground. The motor 125 then rotates the rotating cylinder 126, causing the roller brush on its surface to quickly clear the snow from the ground. Since the rotation direction of the rotating cylinder 126 is the same as the movement direction of the small snowplow 11, it will push the snow towards the small snowplow. The snowplow 11 pushes the snow from the front, and most of the heavier snow chunks and wet snow, after being rolled up by the brush bristles, will fall directly onto the roadside adjacent to the lane due to gravity along a short parabolic trajectory, forming a temporary snow strip. At this time, most of the snow thrown will first hit the bottom surface of the splash plate 128. The splash plate 128 is used to control the throwing height of the snow, so that when the snow hits the bottom surface of the splash plate 128, it can quickly settle down, avoiding the situation where snow water mixed with mud spreads over a large area and causes secondary pollution to the road surface and air. The splash plate 128 can limit the snow's trajectory, causing the snow to concentrate around the bottom of the splash plate 128, resulting in a more concentrated snow layer that is easier for a snowplow to collect later. After the rotating drum 126 has finished clearing the surface snow, some of the compacted snow layer formed by repeated vehicle traffic will come into contact with the surface of the guide plate 123. The compacted snow layer will be shoveled up, and then the guide plate 123 will be tilted to one side to push and pull the compacted snow layer away, reducing the accumulation of the compacted snow layer and exposing the road surface directly. This effectively prevents the compacted snow layer from being further compressed and hardened by subsequent vehicle traffic, and to a certain extent blocks the risk of the residual snow layer refreezing into black ice due to the low temperature environment. The exposed road surface can restore the road surface friction coefficient to the greatest extent.

[0025] like Figures 5 to 8 As shown, a limiting plate a3 is fixedly connected to the outer surface of the snow cover 122 and located at the outer edge of the slot a1. The other end of the buffer wire a5 is fixedly connected to the inner wall of the limiting plate a3. A snow scraper a4 is provided on the inner wall of the snow cover 122. The snow scraper a4 is located on the outer surface of the rotating cylinder 126.

[0026] When the rotating drum 126 is continuously driven by the motor 125, the gap between the roller screens on the surface of the rotating drum 126 will slide on the surface of the snow scraper a4. At this time, the protruding position of the corner of the snow scraper a4 will slide in the gap between the two sets of roller screens. Under the obstruction of the snow scraper a4, the snow accumulated on the surface of the rotating drum 126 and between the roller screen gaps will be squeezed and pushed out, reducing the continuous accumulation of snow on the surface of the rotating drum 126. Clearing the snow can effectively reduce the pressure on the bearings and drive shaft and reduce wear. At the same time, when the snowplow stops, there is no need for employees to spend time cleaning the snow inside the roller screen. After freezing overnight, the snow will not freeze on the surface of the rotating drum 126, which will affect the use of the snowplow the next day. In the south, low-temperature wet snow will accumulate and freeze on the surface of the rotary screen. When the rotating drum 126 rotates to remove snow, the screen bars on the surface of the rotary screen will directly hit the surface of the impact rod a6. Under the violent impact, the ice on the surface of the screen bars will be broken. The broken ice will fall down quickly, effectively reducing the accumulation of ice on the surface of the screen bars.

[0027] Working principle: The small snowplow 11 moves the protective cover 12 to the top surface of the snow pile. At this time, the hydraulic actuator 111 rotates the protective cover 12 by 30°. Simultaneously, the hydraulic pump 121 pushes the snow shield 122, causing the roller brush on the outer surface of the rotating cylinder 126 to be 10cm off the ground. The motor 125 then rotates the rotating cylinder 126, causing the roller brush on its surface to quickly clear the snow from the ground. Since the rotation direction of the rotating cylinder 126 is the same as the movement direction of the small snowplow 11, it will remove the snow... The snow is pushed towards the front of the small snowplow 11. Most of the heavier snow and wet snow, after being rolled up by the brush bristles, will fall directly onto the roadside adjacent to the lane due to gravity along a short parabolic trajectory, forming a temporary snow strip. At this time, most of the snow thrown will first hit the bottom surface of the splash plate 128. The splash plate 128 is used to control the throwing height of the snow, so that when the snow hits the bottom surface of the splash plate 128, it can quickly settle down, avoiding the situation where snow water mixed with mud spreads over a large area and causes secondary pollution to the road surface and air. After the rotating drum 126 has finished clearing the surface snow, some of the compacted snow layer formed by repeated vehicle traffic will come into contact with the surface of the guide plate 123. The compacted snow layer will be shoveled up, and then the angle of the guide plate 123 will be used to push and pull the compacted snow layer to one side, reducing the accumulation of the compacted snow layer and exposing the road surface directly. This effectively prevents the compacted snow layer from being further squeezed and hardened by subsequent vehicle traffic, and to a certain extent blocks the risk of the residual snow layer refreezing into black ice due to the low temperature environment. The exposed road surface can restore the road surface friction coefficient to the greatest extent. When the rotating drum 126 is continuously driven by the motor 125, the gap between the roller screens on the surface of the rotating drum 126 will slide on the surface of the snow scraper a4. At this time, the protruding position of the corner of the snow scraper a4 will slide in the gap between the two sets of roller screens. Under the obstruction of the snow scraper a4, the snow accumulated on the surface of the rotating drum 126 and between the roller screen gaps will be squeezed and pushed out, reducing the continuous accumulation of snow on the surface of the rotating drum 126. Clearing the snow can effectively reduce the pressure on the bearings and drive shaft and reduce wear. At the same time, when the snowplow stops, there is no need for employees to spend time cleaning the snow inside the roller screen. After freezing overnight, the snow will not freeze on the surface of the rotating drum 126, which will affect the use of the snowplow the next day. In the south, low-temperature wet snow will accumulate and freeze on the surface of the rotary screen. When the rotating drum 126 rotates to remove snow, the screen bars on the surface of the rotary screen will directly hit the surface of the impact rod a6. Under the violent impact, the ice on the surface of the screen bars will be broken. The broken ice will fall down quickly, effectively reducing the accumulation of ice on the surface of the screen bars. When the screen bar impacts the surface of the impact rod a6, the powerful kinetic energy pushes the surface of the impact rod a6, causing the impact rod a6 to drive the swing arm a2 to rotate inside the slot a1. During rotation, one end of the swing arm a2 compresses and pulls the buffer wire a5 on the surface. The compressed buffer wire a5 directly absorbs the kinetic energy generated by the impact of the screen bar. When the screen bar impacts the surface of the impact rod a6, the screen bar will directly collide with the surface of the impact block a12. The instantaneous squeezing force brought about by the impact will first cause the impact block a12 to drive the sliding plate a11 to squeeze and move deeper into the slot a8. The silicone soft block a9 inside the slot a8 will provide simple buffering of the external squeezing force. Before the buffer wire a5 buffers the swinging arm a2, the silicone soft block a9 will provide preliminary buffering of the squeezing of the impact block a12, so as to avoid the screen bar from expanding and wearing when it comes into direct contact with the impact rod a6.
