Embodiment Construction

[0076] 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.

[0077] Compared with the four-stroke engine, the two-stroke engine for the brush cutter can increase the liter power by more than 50%, but measures must be taken in terms of emissions; the lawn mower is a portable tool, and the power is expected to be light and small; The muffler pipe of the enzyme is discharged from the far end; the benefit is that the exhaust gas directly emitted by the engine close to the human is changed to wander ar...

Abstract

A two-stroke LPG engine with an inner metal cover and an outer resin cover for dual-layer cooling and noise control comprises a muffler assembly (F7) having a catalytic hush tube (69); the muffler assembly (F7) is arranged on the two-stroke LPG engine through a muffler pad (F8); the outlet of the muffler assembly (F7) is provided with an inner outlet (F7C2) of the inner metal cover (F7C1), and an outer outlet (F7j2) of the outer resin cover (F7j1) and a transition corner (F7j3) are arranged further outer side, thus realizing dual-layer cooling and noise control. The two-stroke LPG engine with the inner metal cover and the outer resin cover for dual-layer cooling and noise is used for driving a garden machine; the front portion of an LPG miniature propane fuel tank is provided with pipe threads; the fuel enters the engine through a pipe joint and a gas-mix controller; the front portion of the fuel tank is also provided with a safety valve; the tank diameter of the fuel tank is smaller than 100mm, and 465 grams of propane fuel are contained so as to be conveniently replaced by standards; a scavenging path is provided with a filter net, and a filter net is arranged below the scavenging path, thus providing filtering and regulation effect; a catalytic agent is also provided.

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 head with internal and external serrations and a control system are installed on the brush cutter. The four-pronged nozzle of the device, and the long grass pressing wheel that is convenient for pressing grass to keep moisture and grass pattern, to form a low-emission LPG 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 di...
