Low-emission gasoline grass pruning machine with carburetor realizing throat gap atomization

Abstract

The invention relates to a low-emission gasoline grass pruning machine with a carburetor realizing throat gap atomization. According to the invention, gaps and shaking vibrating reeds are added to a throat; a stack-cutting grass pruning steel wire rope replaces a nylon wire for facilitating long-term efficient cutting; a cutting knife disc with inner saw teeth is beneficial to preventing of a cutter back-off phenomenon; 3-8 gaps of a multi-branch nozzle squeeze towards multiple directions in a dispersing way, and by virtue of vibration formed by reciprocating shaking of the multiple vibrating reeds among the multiple gaps distributed on the periphery of an outlet pipe, rapid mixing atomization between liquid and airflow from an air filter can be accelerated, so that poly-oil mixture dispersion is facilitated; and a long grass pressing wheel 74 performs grass pressing for preserving soil moisture and is also applied to knurling on the ground. The cutting knife disc with the inner saw teeth changes the cutter back-off state mainly depending on the inner saw teeth. With a low-emission gasoline engine combining the carburetor with the multiple-branch nozzle with throat gap atomization, double accessory vents and scavenging duct wedge turbulence back flow of a tank block, and double accessory skirts of a piston, the quality and use convenience of the low-emission gasoline grass pruning machine are improved.

Description

technical field [0001] The invention provides a lawn trimmer 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, and belongs 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 logarithm...
