[0012] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0013] Figure 1 This is a cross-sectional structural diagram of the present invention; Figure 2 This is a three-dimensional structural diagram of the present invention; Figure 3 for Figure 1 A frontal view diagram.

[0014] In the diagram: 100, frame; 1, drive shaft; 2, brake coil; 3, armature and drive shaft sleeve; 4, anti-rotation rod; 5, clutch rotor; 6, clutch coil; 7, output sprocket; 8, dust cover; 9, fixing bolt; 10, hexagonal nut. Detailed Implementation

[0015] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a cross-sectional structural diagram of the present invention; Figure 2 This is a three-dimensional structural diagram of the present invention; Figure 3 for Figure 1 A front view schematic diagram. The lightweight, portable clutch and brake for agricultural machinery packaging includes: a frame 100, wherein the frame 100 is provided with through holes; The drive shaft 1 passes through and is adapted to the through hole on the frame 100; Brake coil 2 is sleeved and installed on drive shaft 1, and brake coil 2 and drive shaft 1 are connected and fixed by fixing bolt 9; The armature and drive shaft sleeve 3 are sleeved and installed on the drive shaft 1 and in contact with the brake coil 2.

[0016] A clutch rotor 5 is mounted on the drive shaft 1, and a clutch coil 6 is mounted on the clutch rotor 5. The clutch coil 6 is adapted to the clutch rotor 5.

[0017] A hexagonal nut 10 is installed on the drive shaft 1, and the hexagonal nut 10 is screwed into the drive shaft 1. An output sprocket 7 is sleeved on the clutch rotor 5.

[0018] The output sprocket 7 is equipped with a dust cover 8, and the output sprocket 7 and the dust cover 8 are connected and installed by fastening bolts.

[0019] The dust cover 8 is adapted to the output sprocket 7, and the dust cover 8 is used to cover the drive shaft 1 and the hexagonal nut 10.

[0020] The brake coil 2 and clutch coil 6 are connected and limited by the anti-rotation rod 4.

[0021] The electromagnetic force generated when the clutch coil 6 is energized will attract the armature and the transmission shaft sleeve 3, thereby driving the output sprocket 7 to transmit the load.

[0022] The clutch rotor 5 and the anti-rotation rod 4 work together to effectively solve the problem of wire entanglement. When the drive shaft 1 engages the brake, the clutch coil 6 must be de-energized.

[0023] The electromagnetic force generated by the energized brake coil 2 will attract the armature and the transmission shaft sleeve 3. Since the brake coil 2 is locked to the frame 100, the drive shaft 1 will be braked.

[0024] The dust cover 8 can effectively protect the internal bearings from sand, water, impurities and foreign objects, thus preventing them from shortening their lifespan.

[0025] The coil and armature components are made of high-performance electrical pure iron to ensure their flexibility in engagement and disengagement, as well as their transmission and braking torque.

[0026] The transmission and braking components are made of high-strength steel and nitriding process to ensure durability.

[0027] Adopting a modular pre-installed design, it is lightweight and can be installed by one person, eliminating the tedious installation and debugging process. The brake coil module 2 can be directly installed on the frame 100 and the clutch module can be inserted into the drive shaft 1. The wiring terminals use waterproof and dustproof quick-connect connectors, which are convenient to use.

[0028] The structural upgrade eliminates the rotating brush, resulting in a compact size that allows for continued use in limited spaces while reducing the failure rate.

[0029] After installation, with neither the brake nor the clutch solenoid coil energized, the drive shaft 1 idles. When it is necessary to drive the output sprocket 7 for transport, the brake coil 2 must be de-energized, and the clutch coil 6 must be energized. The electromagnetic force generated by the clutch coil 6 will attract the armature and the drive shaft sleeve 3, thereby driving the output sprocket 7 to transmit the load. The combination structure of the clutch rotor 5 and the anti-rotation rod 4 can not only effectively solve the problem of wire entanglement, but also solve the problems of easy wear and tear, complex installation and space occupation compared with the traditional rotating brush structure.

[0030] When the drive shaft 1 needs to be braked, the clutch coil 6 must be de-energized, and the brake coil 2 energized. The electromagnetic force generated by the brake coil 2 will attract the armature and the drive shaft sleeve 3. Since the brake coil 2 is locked to the frame 100, the drive shaft 1 will be braked. The dust cover 8 can effectively protect the internal bearings from sand, water and other foreign objects that may shorten their lifespan. The brake coil 2, clutch coil 6 and armature and transmission shaft sleeve 3 are pre-assembled separately, making the clutch module lightweight and easy to install by one person.

[0031] All standard parts used can be purchased from the market, and can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology, and the structure and principle of the components known to those skilled in the art can be known by those skilled in the art through technical manuals or conventional experimental methods.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
