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, an improved long main aluminum rod for the brush cutter provided by the present invention is loaded into the machine as a catalyst muffler tube, and used F41 Screw fastening; Exhaust gas is passed through the muffler assembly and the catalyst muffler pipe 69, and then through the long main aluminum rod, and discharged from the gap near the cutter at the end of the aluminum rod or the small hole gap.

[0077] Compared with four-stroke engines, two-stroke engines for brush cutters can increase the power per liter by more than 50%, but measures must be taken in terms of emissions; lawn trimmers are portable tools, and the power is expected to be light and small; the original long pole is replaced with multiple honeycombs and catalysts The muffler pipe is discharged from the far end; the benefit is that the exhaust gas directly discharged by the engine close to pe...

Abstract

The invention discloses an LPG engine with a semi-balance drift angle and parabola mean camber line wing-shaped blade. A balance drift angle phi is formed between an angle bisector from the two side edges of an opening of a C-shaped ring (56a), additionally arranged on a crankshaft (57) of the LPG engine, of a crankshaft valve (56) to the circle center angle of the circle center of the crankshaft and a center connecting line from the circle center of the crankshaft to the circle center of a large head of a connecting rod, selecting is actually conducted in the range from 2 degrees to 22 degrees, and the value of 10 degrees is primarily used at present. According to a semi-balance method of a single-cylinder engine, the exciting force amplitude and compound upsetting moment of a resultant force elliptic equation are reduced, drift angle balancing is actually the appropriate offsetting of a balance gravity center, the inappropriate semi-balance of a single cylinder is improved, and the mechanism is worthy of being further explored in detail by people in the future. An inner metal cover, an outer resin cover and a logarithm runner (F7j3) are arranged on a silencer so that double-layer cooling and noise elimination can be facilitated. The problem that the original taper of a magnetic flywheel axially floats is solved. An arc equation of the blade is determined. The outer end of the blade is a sharp end and provided with a cutting edge, and an entanglement can be cut off easily.

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 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 diffe...
