TECHNICAL FIELD
[0001] The utility model relates to ploughing equipment technical field, concretely relates to a harrow subassembly for ploughing. BACKGROUND
[0002] The harrow subassembly for ploughing is a key component in agricultural machinery, widely used in soil ploughing and leveling operations. With the development of modern agriculture, the requirements for ploughing efficiency, quality and environmental protection are continuously improving, prompting the continuous progress of harrow subassembly technology. An ideal harrow subassembly should have a high-strength structure to cope with complex and variable soil conditions, while having a flexible adjustment mechanism to adapt to different ploughing needs. However, despite the continuous development of technology, there are still some problems with existing equipment that need to be addressed.
[0003] The existing harrow subassembly for ploughing has obvious limitations in many aspects. First, in terms of cost, the high initial purchase cost and frequent maintenance requirements increase the economic burden of users, especially for small farmers, which constitutes a significant financial pressure. Second, these devices are usually large in size, not only occupying a large amount of storage space, but also being inconvenient to transport and operate, especially in narrow fields, which affects the work efficiency. Finally, convenience is also a major shortcoming of existing technology: the lack of simple and intuitive adjustment mechanism makes it difficult for users to quickly and accurately adjust the device parameters; the carrying and installation process is complex, usually requiring multiple people to work together or using lifting equipment, increasing labor costs and potential safety risks. These problems limit the application range and user experience of existing harrow subassembly, so it is urgent to improve it through technological innovation. SUMMARY
[0004] The purpose of the utility model is to overcome the above problems and provide a harrow subassembly for ploughing. To achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A harrow subassembly for ploughing, comprising a harrow blade, a harrow shaft, a rotating assembly and a bearing assembly; the harrow subassembly is symmetrically arranged left and right; the harrow blade is fixed at both ends of the harrow shaft; the rotating assembly is in sliding fit with the harrow shaft through the bearing assembly; the bearing assembly is fixed inside the harrow blade;
[0006] The harrow subassembly is symmetrically arranged left and right, ensuring balance and stability during operation; the harrow blade is fixed at both ends of the harrow shaft, providing firm structural support and ensuring good contact with the soil and effective ploughing capacity. The rotating assembly is in sliding fit with the harrow shaft through the bearing assembly, allowing the rotating assembly to rotate smoothly around the harrow shaft, enhancing operational flexibility and adaptability. In addition, the design of the bearing assembly fixed inside the harrow blade not only protects the internal mechanical components from external environmental influences, but also ensures smooth operation of the rotating assembly, reducing wear and maintenance requirements.
[0007] As an improvement, the rotating assembly includes a rotating sleeve and a rake bar; the rotating sleeve is hollow and fitted on the outside of the rake shaft; the rake bar is welded in the middle of the rotating sleeve.
[0008] This design allows the rotating sleeve to rotate freely around the rake shaft, providing flexibility and adaptability. The rake bar is welded in the middle of the rotating sleeve, ensuring the stability of the structure and the effective transmission of power. This layout not only enhances the mechanical strength of the entire assembly, but also enables the rake bar to maintain a stable position and direction during operation, thereby improving the efficiency and quality of plowing. In addition, the hollow rotating sleeve design helps to reduce the overall weight while ensuring sufficient rigidity, further enhancing the durability and operational convenience of the equipment.
[0009] As an improvement, the bearing assembly includes bearings and bearing seats; the bearings are embedded in both ends of the rotating sleeve and are in interference fit with the bearing seats fixed on the rake blades. This design ensures that the rotating sleeve can rotate smoothly and without gaps around the rake shaft, while providing high-precision positioning and stable connection through interference fit, effectively reducing vibration and wear during operation. The bearing assembly not only enhances the mechanical stability of the entire rake assembly, but also prolongs its service life, ensuring the reliability and efficiency of long-term operation.
[0010] The rake blades are fixed to the ends of the rake shaft by nuts, ensuring the stability and reliability of the structure.
[0011] It also includes a washer; the washer is fitted on the rake shaft and installed between the nut and the rake blade. The use of the washer not only evenly distributes the tightening force, preventing the nut from loosening during vibration or long-term use, but also protects the surface of the rake blade from damage caused by direct pressure from the nut. This design detail enhances the durability of the entire assembly, while simplifying the maintenance and adjustment process, ensuring the stable performance of the rake assembly under various working conditions.
[0012] The advantages of the present utility model are:
