Embodiment Construction

[0073] In order to make up for the slight shaking of the main rod caused by the existing mechanism of the brush cutter and grass cutter, an improved long main aluminum rod for the brush cutter provided by the present invention is loaded into the machine as a catenase muffler pipe, and used F41 screws are fastened; the exhaust gas is passed through the muffler assembly and the catalase muffler pipe 69, and then through the long main aluminum rod, and is discharged from the gap near the cutter at the end of the aluminum rod or the small hole gap.

[0074] According to customer requirements, there are four-stroke engines such as 139FA and two-stroke engines such as 1E34F for mowers. Using a two-stroke engine can increase the power per liter by more than 50% compared with a four-stroke engine, but measures must be taken in terms of emissions; the mower is a portable tool, and it is hoped that the power is light and small; if a four-stroke engine is used, the output is less; the ori...

Abstract

The invention discloses a grass trimmer driven by an LPG (Liquefied Petroleum Gas) engine. The grass trimmer is characterized in that a low-emission gasoline engine combined with double auxiliary ventilation openings of left and right improved narrowing box bases, tapered-wedge turbulence channeling sheets at scavenging air duct openings and double auxiliary piston skirts is adopted, the carburetor of the grass trimmer is provided with a four-fork nozzle (70a) which is beneficial to be atomized; the grass trimmer is unexpected in emission-reducing and standard-reaching effect; a cutter includes a grass trimming head (54) with a cutting and grass-trimming steel wire (54b) and a steel wire nylon string both which are beneficial to cut for a long term, and the cutter is provided with an external protecting cover (73) arranged on an internal protecting cover (60) and a long-time grass pressing wheel (74) arranged on the external protecting cover, and the roller length of the long-time grass pressing wheel (74) is equal to the grass trimming diameter, thus the cutter is convenient to press grasses, preserve soil moisture and decorate grasslands. Propane in a micro propane fuel tank reaches 99% and has few impurities. The micro propane fuel tank is made of a high-pressure extrusion die. The grass trimmer is safe, environmentally friendly, easy to exchange and universally applied to multiple countries, thus the grass trimmer is very popular for international markets.

Description

technical field [0001] The invention provides a lawn trimmer and a grass trimmer used for cutting shrubs in places such as flower beds, courtyards, parks and roads, and in the shape of flowers and trees, and belongs to the field of garden machines. Using the innovative method of indirect discharge after passing through the 1.5-meter catalase muffler pipe, in order to expand the use, a mowing head with cutting stacks and mowing steel wires, a cutting disc with internal and external serrations and carburetor are installed on the brush cutter The four-pronged nozzle of the device, and the long grass pressing wheel for easy grass pressing and moisture retention and grass pattern, to form a low-emission gasoline brush cutter. Combustion chamber with function wave and matching with ignition device for internal combustion engine with movable receiving electrode and micro-moving discharging electrode, double auxiliary skirt on piston skirt to reduce hydrocarbon emission, and logarithm...
