Application of carbon fiber on the grass-mowing machine

Abstract

The invention discloses an application of carboform line to a lawn mower, wherein the carboform threads are stuck to a bond to form the carboform line. The good wear-resisting property of the carboform thread and high intension in an axial direction prolongs the service life of the carboform as a line of cut of the lawn mower and makes the line changing frequency greatly decreased, thereby simplifying the manipulation; meanwhile, a wire spool for winding the line of cut on a work head can be arranged very little or not arranged, thereby reducing the weight of the lawn mower and lowering the manufacturing cost.

Description

technical field [0001] The invention relates to an application of carbon fiber to a mower, in particular to an application of a carbon fiber thread to a mower. Background technique [0002] With the development of engineering technology and material science, the requirements for material performance are getting higher and higher. Advanced composite materials have become an extremely important engineering material due to their excellent performance. The research, development and application of composite materials have always been a high priority. One of the important contents of science and technology materials technology, and carbon fiber occupies a pivotal position in this field; carbon fiber is a high-performance material produced with the development of the aerospace industry in the 1960s. Carbon fiber is mainly composed of carbon elements. A special fiber whose carbon content varies with different types. Carbon fiber has the characteristics of general carbon materials, s...

Problems solved by technology

[0003] Usually, outdoor gardening cutting tools such as lawn mowers are equipped with cutting knives and saws for trimming branches, leaves, lawns, etc., but the lawn mowers that appear on the market generally use nylon PA66 to make cutting lines to replace conventional metal blades. , in the high-speed rotation state of the mowing head, the cutting wire is used as a knife saw to cut the grass, which not only reduces the weight of the mower itself, makes the operator not easy to fatigue when cutting, but also reduces the cost of the mower However, there are also deficiencies in replacing metal blades with nylon cutting wires. The main reason is that the nylon material itself has poor wear resistance and low strength, which often causes the cutting wires to wear and break during the mowing process. In order to make up for this deficiency, the custom The best way is to set a winding disc with a larger diameter on the mowing head, which is used to wind the cutting line in circles to ensure normal use during the cutting process; in order to ensure the quality and efficiency of mowing grass, during use It is necessary to pay off or change the line in time to supplement the length of the cut grass. The winding reel of the grass head is usually equipped with a pay-off mechanism. , manual pay-off mechanism, etc. During the cutting process, the operator should pay attention to the working status of the cutting line and adjust the cutting line in time. Frequent line change or release during the operation brings a lot of inconvenience to the operation

For some battery-driven lawn trimmers, to drive the winding reel on the working head and the coil on the winding reel, additional driving energy needs to be added, which leads to The cutting time of the lawn mower is shortened. If a backup battery is configured for the mower, the cost of the mower will be increased accordingly.
