Embodiment Construction
[0077] In order to make up for the slight shaking of the main rod caused by the existing mechanism of the brush cutter and grass cutter, an improved long main aluminum rod for the brush cutter provided by the present invention is loaded into the machine as a catenase muffler pipe, and used F41 screws are fastened; the exhaust gas is passed through the muffler assembly and the catalase muffler pipe 69, and then through the long main aluminum rod, and is discharged from the gap near the cutter at the end of the aluminum rod or the small hole gap.
[0078] According to customer requirements, the brush cutter has a four-stroke engine such as 139FA, and a two-stroke engine such as 1E34F. Using a two-stroke engine can increase the power per liter by more than 50% compared with a four-stroke engine, but measures must be taken in terms of emissions; the mower is a portable tool, and it is hoped that the power is light and small; if a four-stroke engine is used, the output is less; the ...

The invention discloses a two-stroke liquefied petroleum gas (LPG) engine capable of achieving buffer scavenging by combining coarse filtration with fine filtration based on auxiliary power analysis. The LPG engine is used for driving garden machines. A gas fuel tank is filled with LPG and comprises a micro propane fuel tank body. The front portion of the micro propane fuel tank body (t20) is provided with a pipe thread. Fuel enters the engine from a pipe joint through a gas mixing controller for working. The front portion of the micro propane fuel tank body is further provided with a safety valve, so that the fuel is prevented from overflowing when exceeding the limit value, and thus the safety effect is achieved. The rear portion of the micro propane fuel tank body is provided with a tank bottom base plate (t20c), and a plurality of base holes (t20d) which are uniformly distributed are formed in the tank bottom base plate (t20c), so that the micro propane fuel tank body is convenient to carry. The tank diameter of the micro propane fuel tank body is smaller than 100 millimeters, and the micro propane fuel tank body is filled with 465 grams of propane fuel so that the micro propane fuel tank body can be replaced conveniently according to the standard. A filter screen in a scavenging channel of the micro propane fuel tank body is a 40-mesh coarse filter screen. A 140-mesh fine filter screen and a scavenging port buffer valve are further arranged below the scavenging channel. A cutter is provided with a plurality of saw teeth. The quality of the garden machines is improved by continuously improving the two-stroke LPG engine.
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 that is convenient for pressing grass to keep moisture and grass pattern, to form a low-emission LPG 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 di...
