Gasoline engine of semibalance parabola-shaped mean camber line wing blade with single cylinder

Abstract

The invention discloses a gasoline engine of a semibalance parabola-shaped mean camber line wing blade with a single cylinder. A silencer assembly (F7) of a catalyst-contained silencing pipe (69) is installed on the two-stroke gasoline engine through a silencer pad (F8). An internal outlet (F7C2) of an internal metal cover (F7C1) is formed in an outlet of the silencer assembly (F7). An external outlet (F7j2) of an external resin cover (F7j1) and a logarithm flow channel (F7j3) are arranged in the outer position, so that double-layer cooling and silencing are facilitated. By the adoption of the gasoline engine, the problem of a magnetic fly wheel that the original taper floats axially is solved. An equation of the arc of the blade is determined; the bending angle is set to be 18 degrees, the chord length b is 20, and a / b=0.45; a is the maximum deflection point of the bow. A middle-rank technician can make a die module of the contour line of the wing-shaped section. The outer end of the blade is a point and is provided with a cutting edge so that entanglements can be cut easily. A balance deflection angle (phi) is formed between the angle bisector from the two side edges of an opening of a C-shaped ring (56a) to the central angle of the circle center of a crankshaft and a central connection line of the circle center of the larger end of a connecting rod, wherein the C-shaped ring of a crankshaft valve (56) is added on the crankshaft (57); the balance deflection angle (phi) ranges from 2 degrees to 22 degrees, and semibalance of the single cylinder is improved.

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...
