Embodiment Construction

[0078] 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.

[0079] According to customer requirements, the brush cutter has a four-stroke engine such as 139FA, and a two-stroke engine such as 1E34F. 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 ...

Abstract

The invention discloses a two-stroke gasoline engine assisting in the aerodynamic analysis and provided with a trimmer valve with a coarse-mesh filter screen and a fine-mesh filter screen. The two-stroke gasoline engine is characterized in that the rotation speed of the two-stroke gasoline engine is 5750-6950 rpm per minute; the filter screen (58) in a scavenging channel is the 60-mesh coarse-mesh filter screen, and the other filter screen (58) arranged under the scavenging channel is the 180-mesh fine-mesh filter screen of the scavenging port trimmer valve. Steam of the engine is dispersedly squeezed out in multiple directions, vibration of reciprocating shake can play the fueling effect on steam flow, and the effects of polymerization oil mixing and divergence mixing can be better achieved when the rapid mixing and atomization of fluid and airflow from an air filter are accelerated, and thus the mixture enters the engine in a more atomized carburetion state. A sickle is provided with a plurality of sawteeth, and the quality of garden machines is improved through the constantly improved and perfected two-stroke gasoline engine.

Description

technical field [0001] The invention provides a shrub cutter belt mower used for cutting shrubs in places such as flower beds, gardens, parks, roads, etc., in the shape of flowers and trees, belonging 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 logarithmic differential...
