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 a brush cutter with a single-cylinder half-balance and parabola wing-shaped blade gasoline engine. A balance deflection angle phi is formed between the angle bisector of a central angle formed by the two lateral sides of an opening of a C-shaped ring (56a) for additionally arranging a crankshaft valve (56) on a crankshaft (57) of the brush cutter and the circle center of the crankshaft (57) and the center connecting line of the circle center of the crankshaft (57) and the circle center of the large end of a connecting rod, and the balance deflection angle is practically selected from 2 degrees to 22 degrees and now ranges from 10 degrees to 18 degrees. The half balance method of the single-cylinder engine is characterized in that the exciting force amplitude and the synthesis capsizing moment of a synthesis elliptic equation are reduced; the deflection angle substantially means that the balance gravity center is properly shifted, the condition that single-cylinder half balance can not be achieved is improved, and the mechanism is worthy of further detailed researching of people in the future. An inner metal cover, an outer resin cover and a logarithm runner (F7j3) are arranged in a silencer so that double-layer temperature reduction and noise reduction can be facilitated. Axial moving of the original taper of a magnetic flywheel is avoided. The equation of the arc shape of a blade is determined, the outer end of the blade is a sharp end and is provided with a blade opening, and winding objects can be cut off.

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...
