Description
TECHNICAL FIELD
[0001] The utility model relates to a grass cutter with switching working state function. BACKGROUND
[0002] In agricultural production and animal husbandry, the grass cutter is a common device, mainly used for cutting long grass or straw, so as to facilitate feed processing or other purposes. The traditional grass cutter usually adopts a fixed mounting structure, that is, the grass cutter body and the rack are directly fixed together by welding or bolts. Although this design can provide better stability, it has certain limitations. For example, under different working requirements, it may be necessary to adjust the working state of the grass cutter, such as switching to the grass crushing mode or the whole grass mode. However, many grass cutters in the prior art do not design a convenient state switching mechanism, resulting in poor adaptability of the device and difficulty in meeting the needs of various use scenarios.
[0003] Most of the grass cutters on the market currently adopt a fixed connection method. This structure is often inconvenient when maintenance or replacement of parts is needed. For example, if welding is used for fixation, cutting and re-welding are needed when disassembling or replacing parts, which is complex to operate and has high maintenance cost. If bolt connection method is used, tools are still needed for disassembly when adjusting or replacing, which is low in work efficiency. In addition, the traditional fixed connection method may be loose due to vibration or external force during equipment operation, thereby affecting the stability and safety of the equipment.
[0004] In addition, although some grass cutters have certain state switching function, their switching method is usually complex, such as needing to manually adjust multiple fixed points or relying on additional support structure for adjustment, resulting in cumbersome operation process and poor user experience. At the same time, some devices have the problem of unstable structure during switching, such as loose connection parts or inaccurate positioning, which may affect the normal use of the device and even cause safety hazards. Therefore, how to design a grass cutter that can quickly switch working state while ensuring the stability and reliability of the device has become a problem that technicians in the field need to solve.
