Embodiment Construction

[0078] In order to compensate for the slight shaking of the main rod caused by the existing mechanism of the brush cutter, the improved long main aluminum rod for the brush cutter provided by the present invention is installed in the machine as a catalase muffler tube and used F41 screws are fastened; the exhaust gas passes through the muffler assembly and the catalase muffler tube 69, and then through the long main aluminum rod, and is discharged from the gap or small hole at the end of the aluminum rod near the cutter.

[0079] According to customer requirements, brush cutters are available with four-stroke engines such as 139FA and two-stroke engines such as 1E34F. Compared with the four-stroke engine, the two-stroke engine can increase the power by more than 50%, but measures must be taken in terms of emissions; the lawn mower is a portable tool, and it is hoped that the power is small; if the four-stroke engine is used, the output is less; the original long rod Changed to a ...

Abstract

The present invention relates to a catalyst scavenging petroleum brush cutter. In a scavenging channel of the catalyst scavenging petroleum brush cutter, a two-stroke petroleum engine of a catalyst roll is added, so that the up-to-standard effect of emission reduction is achieved. The catalyst roll (59) for emission reduction is arranged in the scavenging channel near a process sheet (55) in the scavenging channel; and catalyst roll containing platinum, prhodium, pindium and iridium has a catalyst effect and a noise control filtration regulation function on flowed gas, and has certain time delay difference and a noise abatement function as well as a block regulating function, so that air flow noise and HC emission are ingeniously reduced. A cutting disc (64) with an inward sawtooth (642) is beneficial for the prevention of cutter back-off; a four-branched nozzle (70a) facilitating atomization is arranged on a carburetor of an engine; a cutter is provided with an outer protective cover (73) mounted on an inner protective cover (60); and the cutter is provided with a plurality of outer sawteeth and inner sawteeth, so that the condition that the brush cutter cannot cut the brushes is improved. The emission of the brush cutter is little, and an emission port is away from operators, so that the quality and convenience of the brush cutter are improved through various measures.

Description

Technical field [0001] The invention provides a brush cutter with a lawn mower used for cutting shrubs in flower beds, gardens, parks, roadsides and other places, and belongs to the field of gardening machines. Using the innovative method of indirect discharge after passing through the 1.5-meter catalase muffler tube, in order to expand the use, the brush cutter is equipped with a cutting head with a cutting wire for cutting grass, a cutting disc with internal and external serrations, and petrol. The four-pointed nozzle of the device, and the long grass roller that is convenient for pressing the grass to maintain moisture and the grass pattern, to form a low-emission gasoline brush cutter. Combustion chamber with function wave and ignition device for internal combustion engine with movable receiving electrode and micro-moving discharge electrode. There are double auxiliary skirts on the piston skirt to reduce hydrocarbon emissions, and the logarithmic differential of the piston ...
