Description

Technical Field

[0001] This utility model belongs to the field of grain unloading technology for harvesters, and specifically relates to an electric grain unloading transmission assembly. Background Technology

[0002] In the existing field of harvester unloading duct drive technology, traditional mechanical drive methods typically rely on precision mechanical structures such as gears and belts for speed regulation. This traditional drive mode not only has a relatively narrow speed range but also low energy conversion efficiency, and is prone to a gradual decline in the overall system performance due to frictional losses between mechanical components.

[0003] On the other hand, while hydraulic drives offer a wider speed range to some extent, they also pose a potential risk of hydraulic oil leakage in practical applications. This risk not only adversely affects the system's pressure stability and driving performance but may also lead to additional energy losses due to fluctuations in hydraulic oil performance with temperature changes.

[0004] More importantly, both mechanical and hydraulic drive systems have relatively complex overall structures, occupying a large space and incurring relatively high installation and maintenance costs. Furthermore, due to the inherent limitations of mechanical and hydraulic components, these two drive methods also exhibit significant shortcomings in adaptability and flexibility, making it difficult to meet the diversified, precise, and efficient demands of modern harvester unloading duct drive technology.

The electric motor 4 is driven and connected to the reducer 3, and the mounting bracket 5 is also fixedly connected to the reducer 3. The reducer 3 is driven and connected to the first auger 12, driving the auger to perform uniform circular motion. This can significantly improve grain unloading efficiency, reduce energy loss, and avoid many drawbacks of mechanical and hydraulic drives, such as mechanical friction loss and hydraulic oil leakage, thereby improving the stability and safety of the system. It can achieve uniform rotation of the unloading auger and rapid response to adapt to the grain silo feed rate, enabling the harvester to quickly and accurately respond and match the speed when unloading grain at different harvesting speeds.

[0028] Specifically, the input shaft and output shaft of the reducer 3 are arranged perpendicularly to each other. The electric motor 4 is coaxially connected to the input shaft of the reducer 3, and the output shaft of the reducer 3 is coaxially connected to the first auger 12. The first auger 12 and the second auger 22 can be connected by a universal coupling or a bevel gear transmission pair, which makes the power transmission more direct and efficient, reduces energy loss in the power conversion process, and improves the overall transmission efficiency.

The structure is stable and can effectively support and fix the electric motor 4 and the reducer 3, ensuring the stable operation of the transmission system, while facilitating installation and maintenance.

[0030] Specifically, the connecting plate 6 includes a first side plate 61 and a second side plate 62 that are fixedly connected to each other. The first side plate 61 and the second side plate 62 are integrally formed and can be generated by bending the plate. The first side plate 61 is in contact with the second mounting plate 53 and is connected by bolts. The second side plate 62 is in contact with the reducer 3 and is connected by bolts, which ensures a firm connection between the reducer 3 and the mounting bracket 5 and avoids loosening or damage caused by vibration or impact.

[0031] Specifically, the first side plate 61 and the second side plate 62 are arranged perpendicularly to each other, and the first side plate 61 and the second side plate 62 are connected by a rib plate 63 in the middle, which makes the connecting plate 6 more stable and able to withstand greater force and torque, thus ensuring the reliability and durability of the transmission system. The first mounting plate 52 is arranged perpendicularly to the U-shaped plate 51, and the second mounting plate 53 is arranged parallel to the first mounting plate 52, making the overall structure of the mounting bracket 5 compact and space-saving, while ensuring the stability and accuracy of the transmission system.

[0032] Specifically, a bend 7 is connected between the first cylinder 11 and the second cylinder 21, making the connection between the first roller 1 and the second roller 2 more flexible and adaptable to different installation angles and layout requirements.

[0033] Specifically, the bend 7 is threadedly connected to the second cylinder 21 and secured to the outer side by clamps 8. The connection method is simple and convenient, easy to disassemble and replace, while ensuring the tightness and reliability of the connection. A second flange 71 is fixedly connected to the bend 7, and a first flange 111 is provided on the first cylinder 11. The second flange 71 and the first flange 111 are connected by bolts, making the connection between the first cylinder 11 and the bend 7 more robust, able to withstand greater pressure and tension, and ensuring the stability and safety of the transmission system.
