Low-emission gasoline grass mower with collar cutter and long grass pressing wheel

Abstract

The invention relates to a low-emission gasoline grass mower with a collar cutter and a long grass pressing wheel. The low-emission gasoline grass mower has the advantages that the energy can be saved, the emission can be reduced, the cutting is improved, the soil moisture conservation is improved, the lawn patterns are beautified, the durability is improved and the product quality is improved. The special cutter of the low-emission gasoline grass mower with the collar cutter and the long grass pressing wheel is provided with three collars (75) for cutting. A cutting edge is arranged on each collar. One collar (75) is installed at a position which is coaxial with a grass mowing head (54). A pair of symmetrical fasteners (76) is arranged on the collar (75) and the grass mowing head (54). The other two collars (75) with cutting edges are respectively installed on the fasteners (7) and are used for throwing and cutting. The collars (75) with the cutting edges not only revolve with a cutting shaft for chopping and cutting, but also rotate with the mower for sliding and cutting. Not only can the cutting effect be improved, but also the durability is improved by changing the cutting edges by turns through rotation. The concept is unique. Back-channeling pieces are added onto an air cylinder, skirts are added on a piston. A chopping and mowing steel wire, a low-emission gasoline engine with a throat gap atomization carburetor and a cutter head with internal saw-teeth are provided. The long grass pressing wheel 74 is provided for pressing grass, conserving soil moisture and embossing patterns on a lawn. The carburetor is provided with a multi-fork spray nozzle with throat gaps for atomization. Since various measures are taken, the quality and the convenience of the low-emission gasoline grass mower are improved.

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 machine, and the long pressing wheel for pressing grass to keep moisture and grass pattern, to form a low-emission gasoline lawn mower. 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 differential equi...
