Description

Technical Field

[0001] This invention relates to the field of snowplow equipment technology, and in particular to an impact-resistant external protective component for snowplows. Background Technology

[0002] Snowplows, also known as snow sweepers, are mechanical devices used to remove snow. They mostly come in the form of small vehicles and are commonly used to clear roads, sidewalks, driveways, and other areas that need to be kept snow-free. They are more common in cold northern regions.

[0003] In practical applications, the varying thickness of snow in different regions makes it difficult for the snow-sweeping components at the front of the snowplow to cover all thicknesses of snow, resulting in poor snow-sweeping performance. In addition, the snow at the bottom, under pressure, combines with ice, debris, and other garbage, making it highly adhesive. The snow-sweeping components are not very effective at clearing this type of snow, resulting in a generally slow advancing speed for the snowplow during actual operation.

[0004] Therefore, how to provide an impact-resistant external protective component for snowplows is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One objective of this invention is to provide an impact-resistant external protective component for a snowplow. This invention can effectively sweep snow of different thicknesses simultaneously by driving the snow-sweeping screw to swing up and down, and can also use a snow-sweeping guard plate to protect the screw while shaking and dispersing the snow at the bottom.

[0006] An impact-resistant external protective component for a snowplow according to an embodiment of the present invention includes a snow trolley and a drive motor fixed to the back of the snow trolley. The snow trolley is provided with a belt linkage mechanism, and the output end of the drive motor drives the snow-expelling screw at the front of the snow trolley to rotate through the belt linkage mechanism.

[0007] The belt-connected mechanism includes a swing link, a belt, and a wheel drive assembly. One side of the swing link is fitted inside the belt via an output wheel. The rotation of the output wheel drives the snow-discharging screw to rotate in front of the snow cart. The belt is fitted onto the swing link and the wheel drive assembly. The swing link, belt, and wheel drive assembly are all located inside the snow cart. The wheel drive assembly is directly connected to the output shaft of the drive motor. One side of the wheel drive assembly is connected to an adjustment mechanism. The wheel drive assembly drives the swing link to swing back and forth at the front end of the snow cart through the adjustment mechanism.

[0008] A snowplow guard plate is installed on the side of the snowplow screw away from the snowmobile. The snowplow guard plate is fixed by several sets of partition plates. The bottom of the snowplow guard plate is laterally limited and slid in front of the snowmobile by a clamp-shaped bracket. The middle position of the bottom of the snowplow guard plate is connected to the belt linkage mechanism through a vibrating mechanism. The belt linkage mechanism drives the snowplow guard plate to move back and forth on the side of the snowplow screw through the vibrating mechanism.

[0009] Furthermore, the belt linkage mechanism also includes a corner pulley and a tension pulley. The output pulley and the wheel drive assembly are fitted on the left and right sides of the belt. The tension pulley is located at the bottom of the inner side of the belt via an electric rod that extends and retracts vertically. The corner pulley is located on the outer side of the belt and near the friction wheel.

[0010] Furthermore, the wheel transmission assembly includes a primary pulley and a single tooth. The primary pulley is fixed on one side of the single tooth, and the center of the primary pulley is rotatably mounted inside the snowmobile via a shaft. One side of the single tooth engages with meshing teeth, and one side of the meshing teeth is fixed with a bevel gear set. The bevel gear set consists of two sets of bevel teeth, and each set of bevel teeth is fixed to the output shaft of the drive motor.

[0011] Furthermore, the meshing teeth are fixed to a connecting plate on the side away from the bevel gear group. The side of the connecting plate is rotatably connected to the push rod via a convex shaft. The end of the push rod away from the connecting plate is rotatably connected to the inclined push slide via a shaft pin. The top surface of the inclined push slide and the bottom surface of the vertical wedge are in inclined contact. Both the inclined push slide and the vertical wedge slide on the inner surface of the snow cart via a slider.

[0012] Furthermore, the top of the vertical wedge seat is provided with a movable groove, and a connecting protrusion is slidably connected inside the movable groove. The connecting protrusion is fixed in the middle of the swing link near the output wheel.

[0013] Furthermore, the swing mechanism includes a lever plate and a drive disk, with a first groove and a second groove respectively opened on both sides of the lever plate.

[0014] Furthermore, a convex roller pin is fixed at the outer circle of the top of the drive disc, and the convex roller pin slides in the first groove, limiting the rotation of the drive disc at the bottom of the snow cart.

[0015] Furthermore, worm gears are engaged on both sides of the drive disc, and the worm gears are movably mounted inside the snowmobile via limit seats. A turbine is engaged at the top of the worm gears, and the turbine is fixed to the side of the friction wheel via a rotating coupling.

[0016] Furthermore, the bottom center of the snowplow guard plate is slidably set in the second groove via a bearing, and a pivot hole is opened on the side of the plate surface near the second groove, through which the plate is rotatably set at the bottom of the snow cart.

[0017] Furthermore, a retaining shell is fixedly connected to the top of the swing linkage via a connecting plate. The retaining shell is located on one side of the snow-expelling screw and provides lateral protection for the snow-expelling screw.

[0018] The beneficial effects of this invention are:

[0019] This invention, through the setting of a belt-connecting mechanism, allows the output wheel, friction wheel, tension wheel, and primary pulley to spread the belt. During the process of the drive motor driving the belt through the wheel transmission assembly, the output wheel can drive the snow-removing screw to rotate at the front end of the snow cart, realizing basic snow removal operation. The rotation of the meshing teeth can drive the connecting plate to rotate, and the rotation of the inclined push slide can drive the inclined push slide to slide back and forth inside the snow cart through the push rod, causing the top of the inclined push slide to push and separate from the vertical wedge seat. In this way, the vertical wedge seat can drive the movable slide groove to move upward. The connecting protrusion inside the movable slide groove is fixed to the surface of the swing connecting rod. When the swing connecting rod is subjected to force, it can swing upward with the friction wheel as the center, driving the output wheel and the snow-removing screw to swing at a certain angle to clear the snow accumulated on the top.

[0020] This invention utilizes a corner wheel design. After the swing linkage is driven to swing at a certain angle, the output wheel, friction wheel, and primary pulley are aligned in a straight line. In this state, the corner area of ​​the belt and the friction wheel is flush, preventing the belt from rotating the friction wheel. The friction wheel, through a vibrating mechanism, controls the snow-shoveling guard plate at the front end of the snow-clearing screw. At this point, the snow-shoveling guard plate transitions from a vibrating state to a stationary state, propelled by the snow cart, to insert into the snow accumulation for snow-clearing. Conversely, when the swing linkage swings downward, the belt can effectively drive the friction wheel to rotate under the resistance of the corner wheel. The friction wheel, through the vibrating mechanism, can then drive the snow-shoveling guard plate to move back and forth, dispersing the snow and enabling the snow-clearing screw to perform snow-sweeping operations.

[0021] This invention utilizes a oscillating mechanism. While the snow-sweeping screw is driven to rotate by the connecting mechanism for snow sweeping, the turbine is driven to rotate by the friction wheel, causing the worm gear to rotate. After the worm gear drives the drive disc to rotate, the first sliding groove on one side of the lever plate is resisted by the convex rolling pin on the drive disc surface, causing it to oscillate back and forth around the pivot hole. On the other side, the second sliding groove directly drives the snow-shoveling guard plate to move left and right on the clamp-shaped bracket surface to achieve the snow-dispersing operation. At this time, the snow-sweeping screw is at the bottom front of the snow cart, and the snow-dispersing operation is synchronized with the snow-sweeping screw's snow sweeping. Conversely, when the snow-sweeping screw is at the top front of the snow cart, clearing the upper layer of snow, the snow-shoveling guard plate no longer oscillates but instead achieves snow sweeping through the forward movement of the snow cart. The overall automation adaptability is strong. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0035] refer to Figures 1-8 It includes a snow cart 1 and a drive motor 2 fixed to the back of the snow cart 1. The snow cart 1 is equipped with a belt linkage mechanism 3. The output end of the drive motor 2 drives the snow-expelling screw 4 at the front of the snow cart 1 to rotate through the belt linkage mechanism 3.

[0036] The belt-connecting mechanism 3 includes a swing link 31, a belt 34, and a wheel drive assembly 37. One side of the swing link 31 is fitted inside the belt 34 via an output wheel 32. The rotation of the output wheel 32 drives the snow-expelling screw 4 to rotate in front of the snow cart 1. The belt 34 is fitted on the swing link 31 and the wheel drive assembly 37. The swing link 31, the belt 34, and the wheel drive assembly 37 are all located inside the snow cart 1. The wheel drive assembly 37 is directly connected to the output shaft of the drive motor 2. One side of the wheel drive assembly 37 is connected to the adjustment mechanism 8. The wheel drive assembly 37 drives the swing link 31 to swing back and forth at the front end of the snow cart 1 through the adjustment mechanism 8.

[0037] Snowplow guard plate 7 is installed on the side of snowplow screw 4 away from snow cart 1. Snowplow guard plate 7 is made up of several sets of partition plates. The bottom of snowplow guard plate 7 is laterally limited and slid in front of snow cart 1 by clamp bracket 9. The middle position of the bottom of snowplow guard plate 7 is connected to belt linkage mechanism 3 through vibration mechanism 6. Belt linkage mechanism 3 drives snowplow guard plate 7 to move back and forth on the side of snowplow screw 4 through vibration mechanism 6.

[0038] In this embodiment, after the drive motor 2 starts, it can directly drive the snow-clearing screw 4 at the front of the snow cart 1 to rotate through the belt linkage mechanism 3. The snow-clearing screw 4 thus performs rotational cleaning of the snow. While the wheel transmission assembly 37 is driven by the drive motor 2, one side of it can drive the adjustment mechanism 8 to operate. At this time, the adjustment mechanism 8 can directly drive the swing linkage 31 to swing back and forth at the front of the snow cart 1, thereby driving the snow-clearing screw 4 to swing up and down. This situation occurs when the snow-clearing screw 4 is continuously rotating, so that the snow-clearing screw 4 can effectively clean different positions of the upper and lower layers of snow, effectively improving the snow removal quality and eliminating the need for multiple snow removal operations.

[0039] A snowplow guard plate 7 connected to the snow cart 1 is provided on one side of the snowplow screw 4. The snowplow guard plate 7 is normally stationary. During the snow sweeping process, the snowplow guard plate 7 provides a certain protective effect, preventing large stones or garbage from contacting the surface of the snowplow screw 4. When the snowplow screw 4 is driven to the bottom of the snow cart 1 to sweep the bottom layer of snow, the snowplow guard plate 7 will vibrate left and right under the connection of the vibrating mechanism 6. The snow between the snowplow guard plates 7 is loosened by the vibration. After the snow cart 1 moves forward, the loose snow can be placed under the snowplow screw 4, which facilitates the reciprocating cleaning operation and effectively deals with the bottom layer of snow with high adhesion.

[0040] refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The belt drive mechanism 3 also includes a corner pulley 35 and a tension pulley 36. The output pulley 32 and the wheel drive assembly 37 are fitted on the left and right sides of the belt 34. The tension pulley 36 is located at the bottom of the inner side of the belt 34 via an electric rod. The corner pulley 35 is located on the outer side of the belt 34 and near the friction wheel 33. The wheel drive assembly 37 includes a primary pulley 371 and a single tooth 372. The primary pulley 371 is fixed to one side of the single tooth 372, and the center of the primary pulley 371 is rotatably located inside the snow cart 1 via a shaft. One side of the single tooth 372 is engaged with a meshing tooth 373, and a bevel gear set 374 is fixed to one side of the meshing tooth 373. The bevel gear set 374 consists of two sets of bevel teeth, and each set of bevel teeth is fixed to the output shaft of the drive motor 2.

[0041] In this embodiment, the corner pulley 35 is normally positioned on one side of the friction wheel 33. After passing the corner pulley 35 and the friction wheel 33, the belt 34 forms a certain corner. This corner can effectively enable the belt 34 to drive the friction wheel 33 to rotate. At this time, the snow removal screw 4 is at the bottom front of the snow cart 1 to clear the bottom layer of snow. When the snow removal screw 4 moves to the top front of the snow cart 1, the output wheel 32, the friction wheel 33 and the primary pulley 371 are arranged at a certain angle. In this way, the movement of the belt 34 will slip with the friction wheel 33. The friction wheel 33 will not rotate under the connection of the vibrating mechanism 6 and the snow removal guard plate 7, thus achieving the stationarity of the snow removal guard plate 7. The tension wheel 36 can also adapt to the deformation of the belt 34 by moving up and down through the electric rod, so that no matter how the belt 34 is deformed, it can still achieve a good connection with the output wheel 32 and the primary pulley 371.

[0042] The single tooth 372 fixed on one side of the primary pulley 371 meshes with the meshing tooth 373. The meshing tooth 373 is fixed on one side of the bevel gear group 374, and the other side of the bevel gear group 374 is fixed to the output shaft of the drive motor 2. When the drive motor 2 starts, the bevel gear group 374 directly drives the meshing tooth 373 to rotate inside the snow cart 1, and then drives the primary pulley 371 to rotate through the single tooth 372. Here, the meshing ratio between the single tooth 372 and the meshing tooth 373 can be set to achieve the effect of deceleration or acceleration, thereby achieving the effect of matching the swing speed of the subsequent swing linkage 31 with the rotation speed of the snow removal screw 4.

[0043] refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A connecting plate 81 is fixed to the side of the meshing tooth 373 away from the bevel gear group 374. The side of the connecting plate 81 is rotatably connected to the push rod 82 via a convex shaft. The end of the push rod 82 away from the connecting plate 81 is rotatably connected to the inclined push slide 83 via a shaft pin. The top surface of the inclined push slide 83 and the bottom surface of the vertical wedge seat 84 are in inclined contact. Both the inclined push slide 83 and the vertical wedge seat 84 slide on the inner surface of the snow cart 1 via sliders. A movable groove 85 is provided on the top of the vertical wedge seat 84. A connecting protrusion 86 is slidably connected laterally inside the movable groove 85. The connecting protrusion 86 is fixed in the middle of the swing connecting rod 31 near the output wheel 32.

[0044] In this embodiment, during the rotation of the meshing tooth 373, one side can drive the connecting plate 81 to rotate. The surface of the connecting plate 81 is rotatably connected to one side of the push rod 82 through a convex shaft, while the other side of the push rod 82 is rotatably connected to the inclined push slide 83 through a shaft pin. The convex shaft of the connecting plate 81 is located at the outer circle of the surface of the connecting plate 81. In this way, the rotation of the connecting plate 81 can drive the push rod 82 to reciprocate, thereby realizing the reciprocating lateral movement of the inclined push slide 83 inside the snow cart 1.

[0045] During the movement of the inclined sliding block 83, its top contacts the inclined wedge of the bottom surface of the vertical wedge block 84. After the vertical wedge block 84 is subjected to the resistance force, it slides upward stably inside the snow cart 1. Then, it pushes the connecting protrusion 86 on the side of the swing link 31 near the output wheel 32 through the movable slide groove 85. After the swing link 31 is subjected to the force, it swings around the output wheel 32 as the center, thereby driving the snow removal screw 4 to rise to a certain height and clearing the snow on the top.

[0046] refer to Figure 6The vibrating mechanism 6 includes a lever plate 61 and a drive disc 62. A first groove 65 and a second groove 68 are respectively formed on both sides of the lever plate 61. A convex roller pin 66 is fixed at the outer circumference of the top of the drive disc 62. The convex roller pin 66 slides within the first groove 65, limiting the rotation of the drive disc 62 at the bottom of the snowmobile 1. A worm gear 63 is engaged on both sides of the drive disc 62. The worm gear 63 is movably mounted inside the snowmobile 1 via a limiting seat. A turbine 64 is engaged at the top of the worm gear 63. The turbine 64 is fixed to the side of the friction wheel 33 via a rotating shaft. The snowplow guard plate 7 is slidably mounted in the second groove 68 at the middle of its bottom via a bearing. A pivot hole 67 is formed on the surface of the lever plate 61 near the second groove 68, allowing the lever plate 61 to rotatably mount at the bottom of the snowmobile 1 via the pivot hole 67.

[0047] In this implementation plan, it is important to clarify that the transmission between the friction wheel 33 and the belt 34 is that the belt 34 drives the friction wheel 33 to rotate. The premise for this rotation is that the belt 34 maintains a certain wrap angle with the friction wheel 33 through the wrap angle pulley 35. At this time, the snow removal screw 4, that is, the connection position of the output wheel 32, must be below the horizontal height of the friction wheel 33, and the snow removal screw 4 cleans the bottom layer of snow at the front of the snow cart 1.

[0048] During the rotation of the friction wheel 33, the turbines 64 on both sides rotate. The turbines 64 mesh with the worm gear 63, causing the drive disc 62 at the bottom of the worm gear 63 to rotate. The top of the drive disc 62 slides in the first groove 65 through the convex roller pin 66. At this time, the lever plate 61 is subjected to force and swings around the pivot hole 67. The pivot hole 67 is located close to the side of the second groove 68. In this way, the lever plate 61 can act like a lever and provide a large force to the second groove 68. The bottom middle position of the snow-shoveling guard plate 7 slides in the second groove 68 through the bearing. Under the restriction of the clamp bracket 9, the snow-shoveling guard plate 7 moves back and forth left and right, thereby causing the snow between the snow-shoveling guard plates 7 to be shaken apart, thus facilitating the snow removal work of the snow removal screw 4.

[0049] Conversely, the snow removal screw 4 is located at the top front of the snow cart 1 to clear the upper layer of snow. Due to insufficient wrap angle, the friction wheel 33 and the belt 34 slip, and the snow removal guard plate 7 remains stationary. At this time, in conjunction with the forward movement of the snow cart 1, the snow removal guard plate 7 can be better inserted into the snow chamber in front for subsequent vibration and dispersal operations.

[0050] refer to Figures 1-4 The top of the swing link 31 is fixedly connected to the protective shell 5 by the connecting plate. The protective shell 5 is set on one side of the snow discharge screw 4 and provides lateral protection for the snow discharge screw 4.

[0051] In this embodiment, the presence of the protective shell 5 allows the rotation of the snow-expelling screw 4 to effectively discharge the internal snow to both sides, while also facilitating protection of the rear of the snow-expelling screw 4.

[0052] Working principle: First, start the drive motor 2. The drive motor 2 directly drives the bevel gear group 374 in the wheel transmission assembly 37 to rotate. The bevel gear group 374 drives the single tooth 372 to rotate through the meshing tooth 373 connected on one side. The single tooth 372 drives the primary pulley 371 to rotate. Under the action of the output wheel 32, friction wheel 33, wrapping wheel 35 and tension wheel 36 in the belt linkage mechanism 3, the belt 34 can move, thereby driving the output wheel 32 to rotate. During the rotation of the output wheel 32, it can drive the snow-discharging screw 4 at the front of the snow cart 1 to rotate. Under the protection of the protective shell 5, the snow is swept away.

[0053] While the meshing gear 373 rotates, the connecting plate 81 on one side rotates synchronously. It drives the inclined sliding block 83 to slide laterally back and forth inside the snow cart 1 through the push rod 82. The top of the inclined sliding block 83 contacts the vertical wedge 84 at an angle. The vertical wedge 84 is subjected to force and moves upward. It slides through the movable slide groove 85 and the connecting protrusion 86 on the surface of the swing connecting rod 31. At this time, the swing connecting rod 31 is subjected to force and swings upward with the friction wheel 33 as the center, reducing the wrap angle between the belt 34 and the friction wheel 33. At the same time, the tension wheel 36 is pushed up by the electric rod to ensure the connection between the belt 34 and the output wheel 32 and the primary pulley 371. At this time, the belt 34 normally drives the snow removal screw 4 to rotate. The snow removal screw 4 is subjected to force above the front end of the snow cart 1 to clear the upper layer of snow. Conversely, the swing connecting rod 31 descends. At this time, the friction wheel 33 maintains a good wrap angle connection with the belt 34 through the wrap angle wheel 35, and the friction wheel 33 rotates.

[0054] At this time, the turbines 64 on both sides of the friction wheel 33 are rotated by force, and the worm gear 63 is connected to the drive disk 62 below through the worm gear 63. After the drive disk 62 rotates, the convex roller pin 66 on its top surface can slide inside the first slide groove 65 on one side of the lever plate 61, causing the lever plate 61 to swing around the pivot hole 67 as the center. The other side of the lever plate 61 drives the snow-shoveling guard plate 7 to move stably left and right on the surface of the clamp-shaped bracket 9 through the second slide groove 68, thus shaking off the snow accumulation.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
