Description

Technical Field

[0001] This utility model relates to the field of snow blower impellers, and in particular to a snow blower impeller that prevents clogging. Background Technology

[0002] A snow blower, also known as a snow-spraying machine, is a specialized piece of equipment primarily used to clear snow from highways and urban roads. This equipment efficiently collects and disperses snow, ensuring unobstructed traffic and improving driving safety. Based on their working principle, snow blowers are mainly divided into two categories: spiral type and blade type. They are compatible with various models of loaders or vehicle chassis and can operate independently or in conjunction with snowplows, making them particularly suitable for clearing compacted snow and large areas of accumulated snow.

[0003] As a key component of the snow blower, the impeller (propeller) features a replaceable blade design to adapt to different operating environments and snow conditions. The impeller employs a heavy-duty spoked structure, with its outer shell constructed of steel plates to ensure structural strength and durability. During operation, the operator uses a multi-functional joystick control system located in the cab to precisely control various functions of the snow blower, including snow collection and throwing. Furthermore, the snow-throwing tube of the snow blower has rotation and adjustment functions to meet the needs of different snow-throwing directions and distances.

[0004] In practical applications, if the snow blower impeller operates for extended periods without proper maintenance, there is a risk of caking and blockage, which will negatively impact the overall performance and effectiveness of the equipment. Specifically, after prolonged use, the impeller may accumulate snow, impurities, or ice, forming caking. These caking particles gradually enlarge, occupying the impeller's flow channel space and causing blockage. Once the flow channel is blocked, the impeller's efficiency will significantly decrease, affecting the snow blower's snow-throwing capacity and snow-lifting height. Furthermore, a blocked impeller will increase the equipment's energy consumption and reduce its operational efficiency.

[0005] More seriously, if impeller blockage is not addressed promptly, it can lead to malfunctions in the snow blower, such as motor overload or overheating, and in severe cases, even damage to the equipment. This not only increases maintenance costs but may also affect the lifespan of the snow blower. Utility Model Content

[0006] The main objective of this invention is to provide an anti-clogging snowplow impeller, 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 impeller designed to prevent clogging includes a shroud, side plates, bearing assemblies, a drive roller, and an auger assembly. Two of the side plates are mounted on the side walls of the shroud, the bearing assemblies are bolted to the side plates, a drive roller is mounted between the two bearing assemblies, and the auger assembly is connected to the drive roller. The transmission roller is provided with a transmission gearbox in the middle section and a drive shaft at the tail of the transmission gearbox. The transmission roller is rotated through the drive shaft and the transmission gearbox, thereby driving the auger assembly to rotate. A drive impeller is connected to the drive shaft via an assembly head. A protective cover is provided at the middle of the rear end of the machine cover. The drive impeller is located inside the protective cover. A discharge port is provided at the lower end of the protective cover, and a channel is formed inside the discharge port. A plug is connected to the lower opening of the channel, and the side wall of the plug is provided with multiple layers of sealing rings. Opening the discharge port creates an internal and external pressure difference inside the protective cover, and the rapid rotation of the drive impeller achieves anti-clogging operation.

[0008] In a further preferred embodiment of this application, the bearing assembly includes a bearing housing, a bearing, and a bearing cover. The bearing is installed in the bearing housing, and the bearing cover covers the bearing housing. The round hole on the bearing cover is aligned with the screw hole of the bearing housing. Bolts are inserted into the round hole and the screw hole to fix it to the side plate. The rotating shafts at both ends of the transmission roller are inserted into the bearing. In a further preferred embodiment of this application, the auger assembly is spirally designed, and a support ring is provided inside the auger assembly. The support ring is sleeved on the transmission roller, and the support ring and the transmission roller are fixed together by bolts. A helical gear assembly is provided inside the transmission gear box. The helical gear assembly is installed on the transmission roller and the drive shaft, and the drive shaft drives the auger assembly to rotate through the helical gear assembly. In a further preferred embodiment of this application, the assembly head is mounted on the drive shaft by bolts, the assembly head contacts the drive impeller, and is fixed to the drive impeller by bolts, and a sealing gasket is provided at the connection between the assembly head and the drive impeller; In a further preferred embodiment of this application, the discharge port and the machine cover are welded and fixed, the connection between the discharge port and the machine cover is arc-shaped, the discharge port and the plug are connected by threads, and the cross-section of the plug is T-shaped. In a further preferred embodiment of this application, the multiple layers of sealing rings are equidistantly distributed on the plug, and the sealing rings achieve sealing at the plug and the discharge port. The outer end of the protective cover is provided with a connecting flange.

[0009] Compared with the prior art, the present invention has the following beneficial effects: Power is transmitted to the transmission gearbox via the drive shaft, which in turn drives the transmission rollers and auger assembly to rotate, achieving efficient snow-throwing operations. Simultaneously, the design of the discharge port, combined with the rapid rotation of the drive impeller, creates an internal and external pressure difference during the discharge process, effectively preventing snow accumulation and blockage, and ensuring the smooth operation of the snow blower.

[0010] The discharge port and plug are connected by threads, and the plug has a "T"-shaped cross-section, making operation and maintenance more convenient. Meanwhile, the protective cover design facilitates connection with other components, improving the overall performance of the snow blower. If blockage occurs during the discharge process, the problem can be resolved by adjusting the drive impeller speed or manually clearing the blockage, demonstrating the equipment's strong adaptability and flexibility.

[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, an anti-clogging snow blower impeller includes a housing 1, side plates 2, bearing assemblies 3, drive rollers 4, and an auger assembly 5. Two side plates 2 are mounted on each of the two side walls of the housing 1, and the bearing assemblies 3 are bolted to the side plates 2. A drive roller 4 is installed between the two bearing assemblies 3, and the auger assembly 5 is connected to the drive roller 4 to achieve snow blowing operations.

[0015] The middle section of the drive roller 4 is equipped with a transmission gearbox 8, and the tail of the transmission gearbox 8 is equipped with a drive shaft 6. Through the coordinated work of the drive shaft 6 and the transmission gearbox 8, the drive roller 4 is rotated, which in turn drives the auger assembly 5 to rotate, thereby completing the snow-throwing task. The drive shaft 6 is connected to the drive impeller 7 through the assembly head 9 to ensure the efficient operation of the snow blower.

[0016] A protective cover 14 is located at the center of the rear end of the machine cover 1. The drive impeller 7 is located inside the protective cover 14 to protect the impeller from damage. A discharge port 10 is located at the lower end of the protective cover 14. A channel 11 is formed inside the discharge port 10, and a plug 12 is connected to the lower opening of the channel 11. The sidewall of the plug 12 is provided with multiple layers of sealing rings 13 to ensure a tight seal. When the discharge port 10 is opened, a pressure difference is created inside and outside the protective cover 14. This pressure difference, combined with the rapid rotation of the drive impeller 7, prevents clogging and ensures smooth operation of the snow blower.

[0017] The bearing assembly 3 consists of a bearing housing, a bearing, and a bearing cover. The bearing is installed in the bearing housing, and the bearing cover covers the bearing housing. The round hole on the bearing cover aligns with the screw hole on the bearing housing, and bolts are inserted into the round hole and screw hole to fix it to the side plate 2. The rotating shafts at both ends of the drive roller 4 are inserted into the bearings to ensure the stable operation of the drive roller 4.

[0018] The auger assembly 5 has a spiral design and an internal support ring that is fitted onto the drive roller 4. The support ring and the drive roller 4 are fixed together by bolts. The transmission gearbox 8 contains a helical gear assembly, which is mounted on the drive roller 4 and the drive shaft 6. The drive shaft 6 drives the auger assembly 5 to rotate through the helical gear assembly to improve snow-throwing efficiency.

[0019] The assembly head 9 is bolted to the drive shaft 6. The assembly head 9 contacts the drive impeller 7 and is fixed to the drive impeller 7 by bolts. A sealing gasket is provided at the connection between the assembly head 9 and the drive impeller 7 to prevent oil leakage and ensure stable operation of the equipment.

[0020] The discharge port 10 and the machine cover 1 are fixed by welding. The connection between the discharge port 10 and the machine cover 1 is arc-shaped to reduce stress concentration. The discharge port 10 and the plug 12 are connected by threads. The cross-section of the plug 12 is T-shaped to facilitate operation and maintenance.

[0021] Multi-layered sealing rings 13 are equidistantly distributed on the plug 12, sealing the plug 12 and the discharge port 10 to prevent snow leakage. The outer end of the protective cover 14 is equipped with a connecting flange for easy connection to other components, improving the overall performance of the snow blower. Starting the snow blower's drive unit transmits power to the transmission gearbox 8 via the drive shaft 6. The helical gear assembly inside the transmission gearbox 8 begins to operate, driving the transmission roller 4 to rotate. The rotation of the transmission roller 4 further drives the auger assembly 5 to rotate; the spiral design of the auger assembly 5 enables it to effectively throw the accumulated snow. Simultaneously, the drive impeller 7 rotates at high speed under the drive shaft 6, providing ample power for the snow-throwing operation.

[0022] During snow throwing, the snow is drawn in by the auger assembly 5 and propelled forward along a spiral path, eventually being thrown to the designated location. The design of the shroud 1 effectively protects the internal components from external environmental interference while ensuring the safety of the snow throwing operation. After the snow throwing operation is completed, or when it is necessary to clear the snow inside the snow thrower, the plug 12 on the discharge port 10 can be opened. At this time, a pressure difference is formed inside and outside the protective cover 14, and the airflow generated by the rapid rotation of the impeller 7 helps to discharge the remaining snow from the discharge port 10.

[0023] The multi-layer sealing ring 13 design ensures a tight seal between the plug 12 and the discharge port 10, preventing snow leakage. Simultaneously, the arc-shaped design of the discharge port 10 and the machine cover 1 reduces stress concentration and improves structural stability. If blockage occurs during the discharge process, the problem can be resolved by adjusting the speed of the drive impeller 7 or by manual assistance. The airflow generated by the high-speed rotation of the drive impeller 7 effectively flushes away blockages, ensuring smooth operation of the snow blower. This snow blower impeller with anti-clogging function, through its unique design, achieves efficient and safe snow throwing operations and effectively prevents blockages during the discharge process.
