Low-emission gasoline brush cutter with lantern ring cutting function

Abstract

The invention provides a low-emission gasoline brush cutter with a lantern ring cutting function, which can save energy, reduce emission, improve cutting, enhance a soil moisture conservation effect and beautify patterns of grasslands, and has improved durability and improved quality. A special cutting device of the low-emission gasoline brush cutter is provided with three lantern rings (75) for cutting, each lantern ring is provided with a cutting edge, one lantern ring (75) is concentric to a grass pruning head (54), a pair of symmetric hitches (76) are arranged on the lantern ring (75) and the grass pruning head (54), and the hitches (76) are provided with the other two lantern rings (75) with cutting edges for throwing cutting. The lantern rings (75) with the cutting edges can perform revolution along with a cutting shaft for cutting and also can perform random autorotation for performing sliding cutting, so that the cutting effect is guaranteed, durability is achieved since an autorotation wheel changes the cutting edges, and the conception is ingenious; an air cylinder is additionally provided with a back-flow plate, a piston is additionally provided with a skirt rim, a steel wire rope is adopted for stack cutting and grass pruning, the low-emission gasoline brush cutter with a carburetor realizing gap atomization at the throat is provided with a cutting knife disc with inner saw teeth, and a long grass pressing wheel (74) is arranged for performing grass pressing for preserving soil moisture and is applied to knurling on the ground; the carburetor is provided with a multiple-branch nozzle, realizes gap atomization at the throat and is matched with various measures, and therefore, the quality and the use convenience of the low-emission gasoline brush cutter are promoted.

Description

technical field [0001] The invention provides a shrub cutter and a grass trimmer used for cutting shrubs in places such as flower beds, courtyards, parks and roads, and 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 disc with internal and external serrations and carburetor 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...
