Description

Technical Field

[0001] This utility model relates to the field of snowplow blade changing technology, and in particular to a snowplow quick blade changing device. Background Technology

[0002] Snowplows are specialized equipment for winter road maintenance, primarily used to remove snow and ice from road surfaces to ensure the safety of vehicles, aircraft, and pedestrians. This equipment is widely used in snow removal operations on highways, urban roads, and airport runways. A snowplow mainly consists of a frame, snowplow section, snow shredder, and connecting structures. The coordinated action of these parts efficiently removes snow from the road surface. Frame: As the structural foundation of the snowplow, it supports all key components, providing stable support for the entire vehicle and ensuring good stability even in complex snow removal environments. Snowplow section: This is the core component of the snowplow. Its snowplows precisely and powerfully cut the compacted snow on the road surface through reciprocating motion, thus stripping stubborn snow from the road. Hydraulic system: This system controls the movable frame to drive the snowplow assembly in an orderly manner, enabling hydraulic lifting and deflection operations, making operation flexible and loading / unloading convenient. Snow shredder: This section further processes the cut snow, crushing larger snow chunks for subsequent sweeping and transportation. Snow removal blades, the blades of snowplows, are typically made of wear-resistant materials to ensure their durability. In practical applications, wear-resistant blades can last 130 to 150 hours on smooth roads and 100 to 130 hours on rougher roads. Furthermore, snow removal blades generally have an automatic adjustment function to adapt to different road slopes, thus completing snow removal tasks more effectively.

[0003] In current snow removal operations, snow removal blades, as a key component of snowplows, are responsible for directly contacting and clearing snow and ice from the ground. However, due to prolonged use and friction with the ground, snow removal blades inevitably suffer wear. This wear not only affects snow removal efficiency but may also adversely impact the overall performance of the snowplow. Therefore, regularly replacing worn snow removal blades is particularly important.

[0004] Currently, snow removal blades are mostly secured using multi-bolt connections. This method firmly fixes the snow removal blade to the snowplow's blade using multiple bolts, ensuring its stability and reliability during operation. However, disassembly is time-consuming and labor-intensive. Because multiple bolts are used for fixing, operators must remove each bolt individually when replacing the snow removal blade, which not only increases the complexity of the operation but also prolongs the replacement time. In emergency snow removal missions, this time-consuming operation may affect the overall snow removal progress.

[0005] The cumbersome disassembly and installation process makes the entire blade replacement process time-consuming. This not only reduces the operational efficiency of snowplows but may also increase the labor intensity of operators. Especially in the harsh winter, performing such operations outdoors for extended periods poses a challenge to the health of the operators. Utility Model Content

[0006] The main objective of this invention is to provide a quick blade-changing device for snowplows, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A snowplow quick blade changing device includes a snowplow mounting frame, a bracket, an angle adjustment bracket, a docking frame, and a bucket. The bracket and the angle adjustment bracket are respectively installed at both ends of the snowplow mounting frame, and the docking frame is connected to the angle adjustment bracket. The bucket is installed on the end face of the docking frame. The lower end of the bucket is provided with a snow removal blade, and the upper part of both ends of the snow removal blade is provided with an L-shaped bracket. The L-shaped bracket is connected to the bucket through a first connector and a second connector. The second connector has a connecting strip on its side wall, and a limiting hole is provided on the end face of the connecting strip. Rotating the connecting strip changes the position of the limiting hole, and the limiting hole connects the snow removal blade to the bucket through a fastening bolt.

[0008] In a further preferred embodiment, an anti-slip rubber strip is provided between the bucket and the snow removal blade, the bucket has multiple through holes, and the snow removal blade has blind holes that are adapted to the through holes. Bolts are inserted into the through holes and blind holes to install the bucket and the snow removal blade. In a further preferred embodiment, the inner end of the snow removal blade is provided with a protruding tube, which has a through hole facing the end face of the bucket. The inner hole of the protruding tube is a threaded hole. The snow removal blade is connected to the bucket through the protruding tube to limit the movement and prevent excessive shaking. In a further preferred embodiment, the two L-shaped brackets are symmetrically distributed at both ends of the snow removal blade. The L-shaped brackets and the snow removal blade are designed as an integral part. The L-shaped brackets and the snow removal blade are provided with three holes, and the line connecting the three holes forms a triangle. The ends of the L-shaped brackets are arc-shaped, and round holes are provided at both ends and corners of the L-shaped brackets. In a further preferred embodiment, both the first and second connecting parts consist of connecting bolts, connecting nuts, and anti-slip washers. The connecting bolts are inserted into the round holes on the bucket, snow removal blade, and L-shaped bracket, and the connecting nuts and anti-slip washers are fitted on them, thereby fixing the bucket, snow removal blade, and L-shaped bracket. In a further preferred embodiment, the connecting strip and the second connecting member are connected by a limiting ring and a limiting groove. The side wall of the second connecting member has a limiting groove, and the connecting strip is limited and connected to the limiting groove. The width of the limiting waist hole is consistent with the diameter of the fastening bolt. The surface of the connecting strip is connected with an anti-slip plate by an adhesive. The fastening bolt passes through the limiting waist hole, through the bucket and the snow removal blade, and is fixed by a nut and an anti-slip washer.

[0009] Compared with the prior art, the present invention has the following beneficial effects: Snow blades, as components that directly contact the ground for snow removal, are rationally designed and securely fixed, enabling them to efficiently remove accumulated snow and improve snow removal efficiency. Furthermore, as consumable parts, snow blades are easily replaced thanks to a quick-disassembly mechanism, eliminating the need for complicated operations and saving maintenance time and costs.

[0010] The quick-release mechanism makes snow removal blade replacement simpler and faster. By loosening and rotating the connecting bar, the locking constraint of the snow removal blade can be easily released, allowing it to flip or slide outward around the bolt axis of the first connecting piece, thus separating it from the bucket. This design not only improves the efficiency of snow removal blade replacement but also reduces the difficulty of operation, making the replacement work easy even for non-professionals.

[0011] The quick-release mechanism also ensures the stability and safety of the snow removal blade during operation. The design with multiple fixing points and the use of anti-slip rubber strips effectively prevent excessive shaking or lateral displacement of the snow removal blade during operation, thus ensuring both snow removal effectiveness and operational safety.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 - Figure 4 As shown, a snowplow quick blade changing device comprises the following basic support frame: Snowplow mounting bracket 1: serving as the mounting base for the entire device, firmly fixed to the front end of the snowplow. Hanging bracket 2: installed at one end of the mounting bracket, providing the main load-bearing point and connection foundation. Angle adjustment bracket 3: installed at the other end of the mounting bracket (usually opposite to hanging bracket 2), a key component for adjusting the working angle of the bucket 5. Connecting bracket 4: connected to the mounting bracket via the angle adjustment bracket 3, forming a direct mounting platform for the bucket 5. The adjustment function of the angle adjustment bracket 3 allows the connecting bracket 4 and the bucket 5 on it to change their tilt angle relative to the ground or operational requirements.

[0015] Bucket 5 and Snow Removal Blade 6 Assembly: Bucket 5: Directly mounted on the end face of the docking frame 4, it is the main structure for accommodating and pushing snow. Snow Removal Blade 6: As a consumable part, it is fixed to the lower edge of the bucket 5 and directly contacts the ground for snow removal. It has an integrated L-shaped bracket 7 at both ends. L-shaped bracket 7: Symmetrically distributed at both ends of the snow removal blade 6, with an arc-shaped end design and round holes at both ends and corners. The three round holes (at both ends and corners) form a triangular layout to enhance connection strength and stability.

[0016] Quick-connect mechanism: First connector 8: typically refers to the connecting bolt, nut, and anti-slip washer. It passes through the round holes at the corners of the bucket 5, snow removal blade 6, and L-shaped bracket 7, forming one of the main fixing points. Second connector 9: also composed of connecting bolt, nut, and anti-slip washer. It passes through the round holes at a specific end (usually near the inside of the bucket 5) of the bucket 5, snow removal blade 6, and L-shaped bracket 7, forming another main fixing point. A key feature is that its sidewall (usually the bolt head or a special connecting block) has a limiting groove. Connecting strip 10 is rotatably mounted on the limiting groove of the second connector 9 via a limiting ring or similar structure. The end face of connecting strip 10 has a limiting waist hole 11 (i.e., an oblong hole). Fastening bolt 12: used to lock the position of connecting strip 10. Its diameter precisely matches the width of the limiting waist hole 11. Anti-slip plate: adhered to the surface of connecting strip 10 to increase hand friction during operation.

[0017] Auxiliary Connection and Buffering: Bolt Through-Hole Connection: Multiple through holes are made along the mounting edge of the snow removal blade 6 on the bucket 5, and corresponding blind holes are made at the corresponding positions of the snow removal blade 6. By inserting bolts, an auxiliary fixation is formed between the bucket 5 and the snow removal blade 6, distributing the load and increasing overall rigidity. This is another set of installation points besides the L-shaped bracket 7 connection. Anti-Slip Rubber Strip: Placed between the contact surfaces of the bucket 5 and the snow removal blade 6, it serves to buffer and reduce shock, seal gaps (preventing ice and snow debris from seeping into the friction surface), and increase friction to prevent relative micro-movement. Limiting Protrusion: A protrusion is provided on the end face of the snow removal blade 6 facing the bucket 5. This protrusion is directly opposite the through hole on the end face of the bucket 5. The inner hole of the protrusion is a threaded hole. By screwing a bolt through the through hole of the bucket 5 into the threaded hole of the protrusion, precise limiting and radial constraint of the snow removal blade 6 relative to the bucket 5 is achieved, effectively preventing excessive shaking or lateral displacement of the snow removal blade 6 during operation.

[0018] Loosen and remove the through-hole bolts and cam bolts used for auxiliary fixing. Loosen (usually not completely remove) the nut of the first connector 8. Loosen the nut of the fastening bolt 12 so that it can slide within the limiting slot 11. Rotate the connecting strip 10. Since the connecting strip 10 is mounted on the second connector 9 through the limiting slot, rotation will change the position of its end limiting slot 11. Rotate it to a release position (e.g., so that the long axis of the slot is deviated from the constraint direction of the fastening bolt 12). At this point, the connecting bolt of the second connector 9 is released from its locking constraint due to the rotation of the connecting strip 10, and the entire snow removal blade 6 and its L-shaped bracket 7 can be flipped or translated outward about the bolt axis of the first connector 8, thus easily separating from the bucket 5. Completely remove the bolts of the first connector 8 (if necessary) and remove the old snow removal blade 6.

[0019] Align the corner hole of the L-shaped bracket 7 of the new snow removal blade 6 with the corresponding hole on the bucket 5, insert the bolt of the first connector 8 and initially tighten the nut to form a hinge point. Place the snow removal blade 6 against the bucket 5, ensuring the anti-slip rubber strip is in place. Install and tighten the through-hole bolt and the convex tube bolt. Pass the bolt of the second connector 9 through the corresponding holes at the ends of the bucket 5, snow removal blade 6, and L-shaped bracket 7, and initially tighten the nut. Rotate the connecting strip 10 to its designed working (locked) position, at which point the limiting waist hole 11 should fit onto the fastening bolt 12. Insert the fastening bolt 12 through the limiting waist hole 11 and the corresponding holes on the bucket 5 and snow removal blade 6, and tighten the nut (usually with an anti-slip washer). Finally, fully tighten the nuts of the first connector 8 and the second connector 9.
