Description

Technical Field

[0001] This utility model belongs to the technical field of snow sweeper equipment, specifically relating to a quick-release auger drive assembly for a snow sweeper. Background Technology

[0002] During winter snowfall, snow accumulation often causes road congestion on highways, urban roads, rural roads, and around houses, causing considerable inconvenience to drivers and pedestrians. To ensure unobstructed traffic and minimize or avoid traffic accidents, timely snow removal is essential.

[0003] Existing snow removal mechanisms typically use traditional methods such as gears, belts, or multi-stage sprockets for power distribution and steering, resulting in bulky structures and significant energy losses. Their transmission paths may not be perpendicular or orthogonal, making it difficult to achieve efficient 90° power conversion in a compact space. This makes the entire transmission system layout inflexible and space-consuming. Furthermore, existing augers and drive shafts use welded or integral structures. Once the auger blades wear out or the shaft is damaged, the entire unit needs to be replaced or complex on-site cutting and welding operations need to be performed, resulting in high maintenance costs and long downtime. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a quick-release auger drive assembly for a snow sweeper.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a quick-release auger drive assembly for a snow sweeper, including a power unit and two auger assemblies. The power unit includes a housing, which includes a longitudinal mounting cavity and a transverse mounting cavity. The longitudinal mounting cavity and the transverse mounting cavity are arranged perpendicularly to each other. A worm is installed in the longitudinal mounting cavity, and a worm wheel shaft is provided in the transverse mounting cavity. A worm wheel is fixedly connected to the worm wheel shaft, and the worm and the worm wheel are meshed with each other. Bearing mounting positions are provided at both ends of the longitudinal mounting cavity and at both ends of the transverse mounting cavity. Bearings are provided in each of the bearing mounting positions. The two ends of the worm are connected to two corresponding bearings, and the two ends of the worm wheel shaft are connected to two corresponding bearings. The worm and the worm wheel shaft are rotatably connected to the housing through the bearings. A universal coupling is connected to the outer end of the worm, and an input shaft is connected to the universal coupling. The two auger assemblies are connected to the two ends of the worm wheel shaft.

[0006] Preferably, the end of the worm gear shaft is smaller than the diameter of the body.

[0007] Preferably, the auger assembly includes an auger shaft and blades, the blades being connected to the auger shaft, and a locking screw being provided at the end of the auger shaft connected to the worm gear shaft.

[0008] Preferably, the end of the auger shaft is fitted onto the end of the worm gear shaft and the connection is locked in place by a locking screw.

[0009] Preferably, the top of the housing is provided with a connecting plate for connection.

[0010] The beneficial effects of this utility model are:

[0011] Innovatively adopting an integrated housing design, the mutually perpendicular longitudinal and transverse mounting cavities are integrated into one, forming a robust transmission space. Through the built-in worm gear mechanism, a 90° efficient and high-torque conversion of power from longitudinal input to transverse output is achieved. This structure is extremely compact, significantly reducing the space occupied by traditional multi-stage transmissions and improving transmission efficiency and stability.

[0012] Precision bearing mounting positions are provided at the ends of both chambers of the housing, providing multi-point, highly concentric support for the worm and worm wheel shafts, which greatly enhances the rigidity and rotational accuracy of the transmission shaft and effectively suppresses vibration and noise.

[0013] The diameter of the worm gear shaft end is reduced, allowing the auger shaft end to be directly fitted in and secured with locking screws. This modular design makes disassembly and replacement of a single auger assembly very simple and quick, without disassembling the entire transmission mechanism or using large tools, significantly reducing maintenance costs and time and improving equipment availability.

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Example: A quick-release auger drive assembly for a snowplow, such as... Figures 1-2As shown, the device includes a power unit and two sets of auger assemblies. The power unit includes a housing, which comprises a longitudinal mounting cavity and a transverse mounting cavity, arranged perpendicularly to each other. A worm gear is installed in the longitudinal mounting cavity, and a worm wheel shaft is provided in the transverse mounting cavity. A worm wheel is fixedly connected to the worm wheel shaft, and the worm gear and worm wheel are meshed together. Bearing mounting positions are provided at both ends of the longitudinal mounting cavity and at both ends of the transverse mounting cavity, and bearings are provided in each bearing mounting position. The two ends of the worm gear are connected to two corresponding bearings, and the two ends of the worm wheel shaft are connected to two corresponding bearings. The worm gear and worm wheel shaft are rotatably connected to the housing through the bearings. A universal coupling is connected to the outer end of the worm gear, and an input shaft is connected to the universal coupling. The two sets of auger assemblies are connected to the two ends of the worm wheel shaft.

[0019] The end of the worm gear shaft is smaller than the diameter of the body.

[0020] The auger assembly includes an auger shaft and blades. The blades are connected to the auger shaft, and a locking screw is provided at the end of the auger shaft that is connected to the worm gear shaft.

[0021] The end of the auger shaft is fitted onto the end of the worm gear shaft and the connection is locked in place by a locking screw.

[0022] The top of the housing is provided with a connecting plate for connection.

[0023] First, the entire hinge assembly is hoisted and securely fixed to the predetermined installation position of the main equipment by means of the connecting plate on the top of the housing, which ensures the stability of the entire power transmission foundation;

[0024] The output shaft of the drive source (such as an electric motor or hydraulic motor) is connected to the input shaft, which is then connected to the outer end of the worm gear via a universal coupling. The design of the universal coupling allows for a certain angular and positional deviation between the drive source and the worm gear, reducing the accuracy requirements for installation alignment and facilitating on-site debugging.

[0025] Install the two sets of augers from both ends of the worm gear shaft respectively; fit the hole at the end of the auger shaft directly onto the end of the worm gear shaft with a smaller diameter, and then tighten the pre-set locking screw on the auger shaft. Use the pre-tightening force of the screw to firmly lock the auger shaft onto the worm gear shaft, thereby realizing the reliable transmission of power from the worm gear shaft to the auger shaft.

[0026] Power is output from the drive source and transmitted to the worm through the input shaft and universal coupling. The worm rotates, driving the worm wheel that meshes with it to rotate, thereby changing the power direction from longitudinal (worm direction) to transverse (worm wheel shaft direction).

[0027] The rotation of the worm gear drives the worm gear shaft to rotate. Since the two ends of the worm gear shaft are stably supported on the housing by bearings, the torque can be smoothly transmitted to the two auger shafts connected to its left and right ends at the same time.

[0028] The two auger shafts rotate synchronously in the same direction under the drive of the worm gear shaft, and the blades installed on the auger shafts rotate accordingly.

[0029] Worm gear drives offer a high reduction ratio and torque, making them suitable for heavy-duty operations. The enclosed housing protects the transmission components and ensures lubrication.

[0030] The overall rigid structure and multi-point bearing support enable the mechanism to withstand the uneven loads and impacts that may be generated during the operation of the auger.

[0031] When the auger blades on one side are worn or damaged, the auger assembly can be removed and replaced or repaired by simply loosening the locking screws on that side, without having to disassemble the entire transmission assembly or the auger on the other side, which greatly simplifies the maintenance process.

[0032] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
