[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] Currently, accumulated ice and snow on roads severely impact traffic and require timely clearing. With the increasing number of roads built in my country and rising labor costs, automatic snowplows equipped with snowplows are widely used. However, most current snowplow blades are single-piece structures. When the blade width is large, the entire blade cannot be transported as a whole by the snowplow, requiring it to be disassembled and transported separately. This necessitates reassembly during use, which is difficult, unsafe, and relatively expensive.

[0033] Based on this, please refer to Figure 1 , Figure 2 and Figure 3 The snowplow 1000 provided in this embodiment can effectively improve the aforementioned technical problems. After the snowplow 1000 is installed on a snowplow vehicle, only the left blade 120, right blade 130, and blade 140 need to be removed from the main blade 110. The width of the main blade 110 will not exceed the road regulations' limit on the overall width of the vehicle body, meaning the snowplow vehicle can be used for normal road transport. This solves the problems of secondary installation, high installation difficulty, and poor safety, while also reducing transportation costs. The snowplow 1000 is applied to snowplow vehicles, and all devices equipped with the snowplow 1000 have the same functions as described above, which will not be elaborated upon here.

[0034] The snowplow in this embodiment includes a vehicle body and a snowplow 1000. The snowplow 1000 is typically located in the middle of the vehicle body to clear snow from the ground. Of course, the snowplow 1000 can also be located in other positions on the vehicle body, depending on the available space, and is not limited here.

[0035] Most existing snowplows are made of a single blade, with a width of 3000mm or more. When the blade width is 2550mm or more, the blade needs to be removed during shipping and then reinstalled at the customer's location or designated cleaning site. This process is difficult and unsafe.

[0036] Figure 1 This is a structural schematic diagram of the snowplow 1000 provided in this embodiment. Figure 1As shown, the snowplow 1000 in this embodiment includes a main blade 110, a left blade 120, a right blade 130, and a blade 140. The left blade 120 is detachably connected to one side of the main blade 110, and the right blade 130 is detachably connected to the side of the main blade 110 away from the left blade 120. The blade 140 is detachably connected to the main blade 110, the left blade 120, and the right blade 130. The main blade 110 is used to connect to the body of the snowplow, and the width of the main blade 110 does not exceed the width limit for the snowplow to travel on the road normally. By detachably connecting the left shovel 120 and right shovel 130 to the main shovel 110, and by detachably connecting the blade 140 to the main shovel 110, the left shovel 120 and / or right shovel 130, as well as the blade 140, can be removed from the main shovel 110 when transporting a snowplow equipped with the snowplow 1000, thus meeting the requirements for the snowplow to travel on the road. In other words, the shovel in this embodiment adopts a three-section design. During the transportation of the snowplow, only the small shovels on both sides of the main shovel 110 and the blade 140 need to be removed for normal road travel. The shovel does not need to be completely removed, solving the problems of secondary installation, high installation difficulty, and poor safety, while also reducing transportation costs.

[0037] Specifically, in this embodiment, the left shovel plate 120 and the main shovel plate 110 are detachably connected using threaded fasteners; and / or, the right shovel plate 130 and the main shovel plate 110 are detachably connected using threaded fasteners; and / or, the blade 140 is detachably connected to the main shovel plate 110, the left shovel plate 120, and the right shovel plate 130 using threaded fasteners. The threaded fasteners can be bolts, screws, etc., and are not limited here. Using threaded fasteners, through the helical inclined surface structure of the threads, achieves uniform force distribution, resulting in strong tensile and shear resistance, improving connection strength, and ensuring connection reliability. Of course, the left shovel plate 120 and the right shovel plate 130 can also be connected to the main shovel plate 110 using plug-in or snap-fit ​​methods, and are not limited here. The blade 140 can also be connected to the main shovel plate 110 using plug-in, snap-fit, or other methods, and is not limited here.

[0038] Please continue reading. Figure 1To improve the wear resistance and service life of the snowplow 1000, reducing the need for frequent replacements and lowering maintenance costs, the snowplow 1000 in this embodiment also includes at least one wear-resistant block 160, which is disposed on the blade 140. The blade 140 is prone to wear and thinning during long-term snow removal, requiring frequent replacement. The wear-resistant block 160 increases the thickness of the blade 140, and in this embodiment, the wear-resistant block 160 is disposed in the easily worn area of ​​the blade 140 (the position frequently in contact with ice, snow, or the road surface). Multiple wear-resistant blocks 160 are used in this embodiment, spaced apart on the blade 140. This arrangement improves the wear resistance of the blade 140 while also reducing manufacturing costs. Of course, a wear-resistant coating can also be applied to the surface of the blade 140, or other wear-resistant structures can be used; no limitation is made here.

[0039] In addition, to increase the connection strength and firmness between the main shovel plate 110 and the left shovel plate 120 or the right shovel plate 130, please refer to Figure 3 and combined Figure 1 and Figure 2 In this embodiment, the snowplow 1000 further includes at least one connecting plate 150. The main shovel plate 110 and the left shovel plate 120 are detachably connected via the connecting plate 150, and / or the main shovel plate 110 and the right shovel plate 130 are detachably connected via the connecting plate 150. Specifically, the connecting plate 150 in this embodiment is a rectangular plate. The connecting plate 150 is disposed at the junction of the main shovel plate 110 and the left shovel plate 120, or at the junction of the main shovel plate 110 and the right shovel plate 130. The connecting plate 150 simultaneously covers the main shovel plate 110 and the left shovel plate 120, or simultaneously covers the main shovel plate 110 and the right shovel plate 130. The connecting plate 150 has a first mounting hole and a second mounting hole, the left shovel plate 120 or the right shovel plate 130 has a third mounting hole, and the main shovel plate 110 has a fourth mounting hole. Threaded fasteners pass through the first and third mounting holes to connect the connecting plate 150 to the left shovel plate 120 or the right shovel plate 130. Threaded fasteners pass through the second and fourth mounting holes to connect the connecting plate 150 to the main shovel plate 110. The number of mounting holes can be one or more, and is not limited here. In addition, the connecting plate 150 may be provided with a snap-fit ​​structure for detachable connection with the main shovel plate 110, the left shovel plate 120, and the right shovel plate 130, so that the connecting plate 150 can be fixed by the snap-fit ​​structure before the threaded fasteners are connected, so as to better install the threaded fasteners.

[0040] Figure 2 This is a structural schematic diagram of the snowplow 1000 with rotating component 200 and flipping component 300 provided in this embodiment from a first-view perspective. Figure 3 This is a structural schematic diagram of the snowplow 1000 with rotating component 200 and tilting component 300 provided in this embodiment, viewed from a second perspective. For details, please refer to... Figure 2 and Figure 3 In this embodiment, the snowplow 1000 further includes a rotating assembly 200, which includes a tilting bracket 210 and a first driving member 220. The tilting bracket 210 is connected to the first driving member 220 and is connected to the main shovel plate 110. The first driving member 220 drives the tilting bracket 210 to rotate, thereby driving the main shovel plate 110 to rotate. By setting the rotating assembly 200, the main shovel plate 110 can be tilted to the left or right of the road surface, thereby clearing the ice and snow on the road surface to the left or right side. When the main shovel plate 110 is connected to a left shovel plate 120 and a right shovel plate 130, the rotating assembly 200 can tilt the main shovel plate 110, and also tilt the left shovel plate 120 and the right shovel plate 130 to the left or right together.

[0041] To limit the rotation angle of the deflection bracket and snowplow 1000, please refer to [link / reference needed]. Figure 2 and Figure 3 In this embodiment, the first driving component 220 can be any one of a cylinder, a hydraulic cylinder, or an electric push rod. The rotating assembly 200 in this embodiment also includes a turntable 230, on which a limiting groove 231 is formed. The turntable 230 is coaxially rotatably connected to the swing bracket 210. The fixed end of the first driving component 220 is hinged to the turntable 230, and the movable end of the first driving component 220 is hinged to the swing bracket 210. The connection end between the first driving component 220 and the swing bracket 210 is located within the limiting groove 231. The first driving component 220 is used to drive the swing bracket 210 to rotate relative to the turntable 230. The extension or retraction of the piston rod of the first driving component 220 can drive the swing bracket to rotate relative to the turntable 230, thereby driving the main shovel plate 110 to rotate, or driving the main shovel plate 110, the left shovel plate 120, and the right shovel plate 130 to rotate. By setting the connection end of the first driving component 220 and the deflection bracket to be located in the limiting groove 231, that is, the piston rod part is located in the limiting groove 231, and its extension length is limited by the limiting groove 231, thereby limiting the rotation angle of the deflection bracket, and thus limiting the rotation angle of the main shovel plate 110, the left shovel plate 120 and the right shovel plate 130.

[0042] Specifically, the limiting groove 231 in this embodiment is arc-shaped. The left and right swing angle of the swing bracket 210 in this embodiment can reach 45°. Of course, the swing angle of the swing bracket 210 can also be changed by altering the curvature and length of the limiting groove 231. The swing angle is determined according to actual usage requirements and is not limited here. To ensure the stability of the swing bracket's rotation, there are two first driving members 220 in this embodiment, spaced apart. Correspondingly, there are also two limiting grooves 231. The piston rods of the two first driving members 220 are arranged one-to-one with the two limiting grooves 231. The piston rods of the first driving members 220 pass through the limiting grooves 231 and are hinged to the swing bracket 210 via connecting pins. The end of the first driving member 220 away from the piston rod is hinged to the turntable 230. By pushing and pulling the two ends of the swing bracket 210 back and forth with the two first driving members 220, the swing bracket can be driven to rotate, thereby driving the main shovel plate 110 to rotate. Of course, the number of first driving components 220 can also be one, three, four, or more, as long as it can enable the swing bracket 210 to rotate and drive the main shovel plate 110 to rotate. The specific setting position and number are not limited here.

[0043] To improve the stability of the yaw bracket 210 rotating relative to the turntable 230, please refer to... Figure 1 and Figure 2 In this embodiment, the rotating assembly 200 further includes a wear-resistant plate 240 and a pressure plate 250. The wear-resistant plate 240 is connected to the pressure plate 250, and the wear-resistant plate 240 and the pressure plate 250 are stacked. The wear-resistant plate 240 is connected to the swing bracket 210, and the wear-resistant plate 240 abuts against the side wall of the turntable 230. The pressure plate 250 at least partially covers the top surface of the turntable 230. The pressure plate 250 and the wear-resistant plate 240 are used together to clamp the turntable 230. By providing the wear-resistant plate 240, when the swing bracket 210 rotates relative to the turntable 230, the wear-resistant plate 240 also slides along the side wall of the turntable 230. Through the abutment and cooperation between the wear-resistant plate 240 and the side wall of the turntable 230, the stability of the swing bracket 210 rotating relative to the turntable 230 can be improved. Furthermore, by providing the wear-resistant plate 240 in contact with the turntable 230, friction can be reduced and wear resistance can be improved. In addition, by setting a pressure plate 250, the pressure plate 250 and the wear-resistant plate 240 form a slot, and the pressure plate 250 and the wear-resistant plate 240 together clamp the turntable 230. When the swing bracket 210 rotates relative to the turntable 230, it is always restricted by the pressure plate 250 and the wear-resistant plate 240, which can further improve the stability of the swing bracket 210 rotating relative to the turntable 230.

[0044] Furthermore, in this embodiment, both the wear-resistant plate 240 and the pressure plate 250 are detachably connected to the eccentric bracket 210. Specifically, threaded fasteners such as bolts and screws can be used for connection so that the wear-resistant plate 240 and the pressure plate 250 can be replaced after wear occurs.

[0045] Please continue reading. Figure 2 and Figure 3 In this embodiment, the sway bracket 210 is hinged to the main shovel plate 110. The snowplow 1000 also includes a tilting assembly 300, which includes a tilting bracket 310 and a drive assembly 320. The drive assembly 320 is mounted on the tilting bracket 310. The tilting bracket 310 is connected to the sway bracket 210, and the drive assembly 320 is connected to the main shovel plate 110. The drive assembly 320 is used to drive the main shovel plate 110 to rotate relative to the tilting bracket 310. By setting the tilting assembly 300, the main shovel plate 110 can be tilted, thereby driving the left shovel plate 120 and the right shovel plate 130 to tilt, thereby realizing the adjustment of the tilt angles at both ends of the main shovel plate 110, the left shovel plate 120, and the right shovel plate 130, so as to drive the blade 140 to a state that is in contact with the road surface, thereby ensuring the snow removal effect. Of course, when the left shovel plate 120 and the right shovel plate 130 are not installed, the tilting assembly 300 only drives the main shovel plate 110 to tilt.

[0046] Specifically, the snowplow 1000 in this embodiment further includes a first connecting seat 400 and a tilting shaft 500. The first connecting seat 400 is connected to the main shovel plate 110, and the sway bracket 210 is hinged to the first connecting seat 400 via the tilting shaft 500. Furthermore, to improve the stability and robustness of the sway bracket 210 connection, the snowplow 1000 in this embodiment also includes a second connecting seat 600, through which the sway bracket 210 is connected to the main shovel plate 110. Of course, the first connecting seat 400, the tilting shaft 500, and the second connecting seat 600 can be provided simultaneously or separately; this is not limited here.

[0047] To ensure the snowplow 1000 can avoid obstacles in time when encountering them, thus preventing damage to the blade 140, please refer to [the relevant documentation / reference]. Figure 2 and Figure 3 and combined Figure 4 , Figure 4This is a schematic diagram of the drive assembly 320 provided in this embodiment. The drive assembly 320 in this embodiment includes a second drive member 321, a mounting base 322, a spring 323, a limiting ring 324, and a limiting flange 326. The mounting base 322 has a mounting cavity 325; the spring 323 is disposed in the mounting cavity 325; the limiting flange 326 protrudes from the outer wall of the second drive member 321; a portion of the second drive member 321 is located within the mounting cavity 325, and one side of the limiting flange 326 abuts against the spring 323; a detachable limiting ring 324 is provided on the side of the limiting flange 326 away from the spring, one end of the limiting ring 324 abuts against the limiting flange 326, and the other end is detachably connected to the mounting base 322; the end of the second drive member 321 away from the spring 323 is connected to the main shovel plate 110. Specifically, in this embodiment, the mounting base 322 is connected to the oscillation bracket 210 via a rotating shaft and can rotate around the rotating shaft. Spring 323 is sleeved on second drive member 321. A limiting flange 326 is provided on the outer wall of second drive member 321. Second drive member 321 compresses spring 323 within mounting cavity 325 via the limiting flange 326. A limiting ring 324 is provided on the side of mounting base 322 near main shovel plate 110. The side of limiting flange 326 away from spring 323 can abut against limiting ring 324. Limiting ring 324 is connected to mounting base 322 via bolts or other threaded fasteners, thereby pre-tightening limiting flange 326 and connecting second drive member 321 to mounting base 322. When second drive member 321 is not subjected to external force, limiting flange 326 abuts against limiting ring 324 and spring 323, applying a certain pre-tightening force to spring 323 to fix second drive member 321 to mounting base 322. When the second drive component 321 is subjected to an external force, such as when the blade 140 of the snowplow 1000 encounters an obstacle, the force is transmitted to the spring 323 through the second drive component 321. The spring 323 is compressed, and at this time, the limiting flange 326 and the limiting ring 324 are no longer in contact. The characteristics of the spring 323 are used to achieve the function of buffering and obstacle avoidance, so as to avoid damage to the blade 140.

[0048] In addition to installing the spring 323 in the manner described above, the spring 323 can also be installed at the bottom of the mounting cavity 325. One end of the spring 323 is connected to the bottom of the inner wall of the mounting base 322, and the other end of the spring 323 is connected to the second driving member 321, which can also achieve the function of buffering and obstacle avoidance. In this embodiment, the second driving member 321 can be a cylinder or a hydraulic cylinder, etc., and is not limited here.

[0049] Furthermore, when the second driving component 321 is a hydraulic cylinder or a pneumatic cylinder, the tilting assembly 300 in this embodiment may also include a pressure relief assembly (not shown in the figure). The pressure relief assembly is connected to the second driving component 321 and is used to relieve pressure on the second driving component 321 when the hydraulic or pneumatic pressure of the second driving component 321 exceeds a preset safety value. That is, when the main shovel plate 110 squeezes the second driving component 321 to a certain force during the upward obstacle avoidance process, the pressure on the second driving component 321 is relieved to increase the upward obstacle avoidance stroke of the main shovel plate 110. The dual-stage obstacle avoidance structure of spring 323 obstacle avoidance and hydraulic or pneumatic obstacle avoidance enables the main shovel plate 110, as well as the left shovel plate 120 and right shovel plate 130, to flexibly avoid obstacles of different heights, effectively solving the problems of slow response speed, low reliability, and poor safety of hydraulic obstacle avoidance, and ensuring operational safety and reliability.

[0050] The snowplow 1000 in this embodiment may further include a lifting assembly (not shown in the figure), which is drivenly connected to the main shovel plate 110, or the lifting assembly is drivenly connected to the rotating assembly 200. The lifting assembly is used to drive the main shovel plate 110, the left shovel plate 120, and the right shovel plate 130 to achieve up-and-down lifting movements, so as to remove ice and snow of different thicknesses. The snowplow 1000 in this embodiment may further include a tilt adjustment assembly (not shown in the figure), which is connected to the deflection bracket. The tilt adjustment assembly can drive the deflection bracket to move up and down or adjust the tilt angle relative to the horizontal plane along the width of the road surface, so as to adjust the tilt angle and height of the deflection bracket relative to the road surface, thereby adjusting the tilt angle and height of the main shovel plate 110, the left shovel plate 120, and the right shovel plate 130 relative to the road surface. The snowplow 1000 may also be equipped with other structures according to the actual working conditions, which are not limited here.

[0051] In summary, the snowplow 1000 includes a main blade 110, a left blade 120, a right blade 130, and a blade 140. The left blade 120 is detachably connected to one side of the main blade 110, and the right blade 130 is detachably connected to the side of the main blade 110 away from the left blade 120. The blade 140 is detachably connected to the main blade 110, the left blade 120, and the right blade 130. The main blade 110 is used to connect to the body of the snowplow, and the width of the main blade 110 does not exceed the width limit for the snowplow to travel on the road normally. By detachably connecting the left shovel 120 and right shovel 130 to the main shovel 110, and by detachably connecting the blade 140 to the main shovel 110, the left shovel 120 and / or right shovel 130, as well as the blade 140, can be removed from the main shovel 110 when transporting a snowplow equipped with the snowplow 1000, thus meeting the requirements for the snowplow to be used normally on the road. The shovels do not need to be completely removed, solving the problems of secondary installation, high installation difficulty, and poor safety, while also reducing transportation costs.
