Description
Technical Field
[0001] The utility model relates to the technical field of lawn mowers, in particular to a highly efficient and durable lawn mower blade and a lawn mower. Background Art
[0002] Lawn machines have many names, also known as lawn mowers, lawn cutters, lawn trimmers and grass trimmers. Most common lawn machines are lawn mowers, which are mainly used for garden decoration pruning, grassland greening pruning, urban streets, green scenic spots and pastoral pruning, especially lawns and grasslands in parks, football fields and other grass fields, private villa gardens, and vegetation in agricultural, forestry and animal husbandry farms. They can also be used in autumn harvest. However, lawn mowers have certain limitations when mowing grass on the edges of fields, ends of fields and mountains in rural areas. The main reasons are the uneven terrain, power supply methods, and the weight and portability of the lawn mowers. Today, the commonly used lawn mowers are gasoline lawn mowers, also known as lawn machines, which have a wide range of uses and are mainly used for lawn mowing and beautification in park lawns, green belts, factory lawns, golf courses, home gardens, meadows, orchards and other places.
[0003] According to the search, Chinese patent literature, announcement number: CN209185043U, discloses a lawn mower that is easy to replace the blade. This solution sets a connecting block, pulls out the fixing plate stuck on the top of the connecting block, then unscrews the fixing nuts at both ends of the stud bolts, and pulls out the stud bolts. Through double-layer fixation, the connecting block is made more stable, and then the connecting block stuck in the cutter disc can be taken out, and then the baffle is rotated to push the blade from the outside to the inside, and finally taken out from the mounting groove. Through such a clamping method, the structure is simple, and it is convenient to disassemble and take out, so as to achieve the purpose of facilitating the replacement of the blade. The lawn mower that is easy to replace the blade is set by setting a fixed tray, and the fixed tray is threadedly connected to the shaft rod, so that the connection between the cutter disc and the shaft rod is stable. Through the guide rail, the connecting block and the blade are conveniently installed. Through the limit ring, a clamping block is installed at one end of the blade located in the cutter disc, and the clamping block is clamped with the limit ring, so that the blade can be fixed to avoid instability of the blade, thereby causing greater wear. However, this lawn mower with easy-to-replace blades still has defects during use. The blade head of the device may cause wear due to long-term rigid contact, thereby reducing the durability of the blade. In addition, the device cannot cut weeds in small sections. The weeds may be too long and entangled with the cutter, thereby affecting work efficiency. Utility Model Content
