Description

Technical Field

[0001] This utility model belongs to the technical field of harvester accessories, specifically relating to an electric disengagement drum assembly for a harvester. Background Technology

[0002] Traditional harvester detachment drums primarily rely on mechanical or hydraulic drives, but both have significant drawbacks. Mechanical drives, due to their reliance on gears, belts, and other mechanical structures for speed regulation, suffer from limited speed range, large size and weight, low energy efficiency, and complex and costly maintenance. While hydraulic drives offer more flexible speed regulation, they are prone to leaks, causing environmental pollution and safety hazards, and are sensitive to temperature, affecting system stability and response speed. Furthermore, hydraulic systems are expensive, require professional personnel for installation and commissioning, and with the development of AI and automation technologies, hydraulic transmissions are becoming insufficient in terms of precision, automated control, and mass production. Existing electric detachment drum assemblies for harvesters also face problems such as low working efficiency, insufficient structural strength, and complex installation and maintenance, failing to meet the high-efficiency and rapid production demands of modern agriculture.

[0024] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0025] like Figure 1-5 As shown, an electric detachment drum assembly for a harvester includes a detachment drum 1, a mounting frame 2, and a fixing frame 5. The detachment drum 1 includes a cylinder 11 and a shaft 12. The shaft 12 is rotatably connected to the mounting frame 2 via a rotating bracket. The cylinder 11 is mounted on the shaft 12 via a connector 6. A reducer 3 is mounted on the mounting frame 2, and a motor 4 is mounted on the fixing frame 5. The fixing frame 5 is fixedly connected to the mounting frame 2. The motor 4 is driven by the reducer 3, and the reducer 3 is driven by the shaft 12. This assembly effectively improves the working efficiency of the harvester. By driving the reducer 3 through the motor 4, the detachment drum 1 is rotated, achieving efficient detachment of crops. It is low-cost, highly efficient, reduces manual labor intensity, and has a compact structure that is easy to maintain.

[0026] Furthermore, the mounting bracket 5 is plate-shaped and has a U-shaped bend to form a mounting groove. The motor 4 is installed in the mounting groove, providing a stable mounting platform for the motor 4, effectively reducing the vibration and noise of the motor 4 during operation, and improving the overall operational stability.

[0027] Furthermore, the two ends of the fixing frame 5 extend backward to form a connecting part. The fixing frame 5 is connected to the mounting frame 2 through the connecting part and bolts, making the installation of the fixing frame 5 simpler and faster. At the same time, ribs are connected between the connecting part and the side wall of the fixing frame 5. Lifting holes are provided on both side walls of the fixing frame 5 to ensure the firmness and stability of the connection and facilitate future maintenance and replacement.

[0028] Furthermore, the connector 6 includes a mounting plate 61 and a tapered connecting cylinder 62. The mounting plate 61 is fixedly connected to the shaft 12. The large-diameter end of the tapered connecting cylinder 62 is fixedly connected to the end of the cylinder 11, and the small-diameter end of the tapered connecting cylinder 62 extends into the cylinder 11 and is connected to the mounting plate 61. This enhances the connection strength between the cylinder 11 and the shaft 12, ensuring the stability and reliability of the detached roller 1 when rotating at high speed, while also facilitating installation and disassembly.

[0029] Furthermore, the rotating bracket includes a tapered mounting cylinder 7 and a bearing mounted on the tapered mounting cylinder 7. The shaft 12 is connected to the bearing, and the rotating bracket is fixedly connected to the mounting frame 2, so that the shaft 12 can rotate smoothly, reduce friction and wear, extend service life, and ensure efficient operation when detached from the roller 1.

[0030] Furthermore, the reducer 3 is integrally formed and has four mounting ears 31 spaced apart. Each mounting ear 31 has an elongated hole 311. The mounting ears 31 are connected to the mounting bracket 2 by bolts passing through the elongated holes 311. This makes installation convenient, simplifies the installation process, improves the stability and reliability of the reducer 3, and ensures efficient power transmission.

[0031] Furthermore, the mounting ear 31 is located on the outer middle of the reducer 3. One end of the reducer 3 extends into the fixed frame 5, and the other end extends into the inner side of the rotating bracket, making the entire transmission system more compact and reasonable, reducing space occupation, while ensuring smooth power transmission and improving the overall performance of the harvester.

[0032] Furthermore, the cylinder 11 includes a detachment section and a separation section. The detachment section includes a conical drum 111 and blades, a front detachment tooth 115, and a middle detachment tooth 116 disposed on the conical drum 111. The blades include a spirally arranged front blade 113 and a rear blade 114, which helps to evenly distribute the grain in the cylinder 11 and gradually thresh it, reducing clogging and improving threshing quality. The separation section includes a separation drum 112 and rear detachment teeth 117 and separation teeth 118 disposed on the separation drum 112. When used together, they can more effectively separate the grain from impurities, ensuring the purity of the finally harvested grain and improving the overall operating effect. One end of the separating drum 112 is connected to the mounting frame 2, and the other end is welded to the conical drum 111. The front blade 113, the rear blade 114, the front detachment tooth 115, the middle detachment tooth 116, the rear detachment tooth 117, and the separating tooth 118 are arranged sequentially from the conical drum 111 to the separating drum 112. This orderly arrangement ensures the smooth flow of grains in the drum body 11 for threshing and separation, greatly improving work efficiency.
