Low Emission Gasoline Brush Cutter with Throat Clearance Atomizing Carburetor

Abstract

The invention relates to a low-emission gasoline brush cutter with a throat gap atomization carburetor. The low-emission gasoline brush cutter is provided with a throat, gaps, shaking vibrating pieces, a chopping and mowing steel wire, an internal saw-tooth cutter head, a multi-fork spray nozzle and a grass pressing wheel 74, wherein the steel wire replaces a nylon line to facilitate long-term high-efficiency cutting; the internal saw-tooth cutter head can facilitate cutter relieving; the multi-fork spray nozzle is provided with 3-8 gaps to realize multidirectional dispersive extrusion, and when a plurality of vibrating pieces which shake back and forth and are formed among a plurality of gaps circumferentially arranged on an outlet pipe vibrate, fluid and air flow coming from an air filter are accelerated to be fiercely mixed and atomized to better facilitate oil mixing and dispersion; the grass pressing wheel 74 is used for pressing grass to conserve soil moisture and emboss patterns on a lawn; the internal saw-tooth cutter head changes a cutter relieving state by virtue of internal saw-teeth; since the carburetor of a low-emission gasoline engine is provided with the multi-fork spray nozzle with throat gaps for atomization and is matched with tank base dual-auxiliary air vents, a scavenging duct port for wedge turbulent flow back-channeling and piston dual-auxiliary skirts in use, the quality and the convenience of the low-emission gasoline brush cutter 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...
