The carrying module is used for fixing the dust collection processing module, and carrying the electric saw and other tools which are not used, so that the use is convenient. Especially for the pruning work needing movable operation, it is very labor-saving and practical.
The dust collection processing module comprises a dust collection cover 5, a cyclone dust collection barrel and a buoyancy collecting barrel which are communicated with a gas path;
the dust hood 5 is of a horn mouth structure and specifically comprises a hood bottom plate 6, the hood bottom plate 6 is used for being installed and fixed on the front machine plate through a bolt piece, and a strip-shaped hole is formed in the hood bottom plate 6 and used for enabling a guide plate and a chain to pass through.
The hood bottom plate 6 is provided with a flare opening on the peripheral side for better sucking a large amount of polluted air near the cutting position of the electric saw.
An air suction opening is formed in the cover bottom plate 6, an air suction pipe 7 is communicated with the air suction opening, the air suction pipe 7 is a flexible pipe, preferably an organ pipe, and the dust hood 5 is communicated with an air passage of the cyclone dust removal barrel through the air suction pipe 7.
The cyclone dust removal barrel comprises a cyclone barrel 8 and a dust collection barrel 9, an air inlet 10 is formed in the side wall of the cyclone barrel 8, an air outlet 11 is formed in the top of the cyclone barrel 8, an air suction joint is arranged on the air inlet 10, and the air suction joint is detachably communicated with one end of the air suction pipe 7.
The top of the cyclone cylinder 8 is provided with a fan 12, the fan 12 is used for pumping air out from the air outlet 11, the pumped air forms spiral rotation in the dust removing cylinder, so that lighter air is pumped out from the air outlet 11, and heavier particles sink and are collected in the dust collecting barrel 9.
The first collection of particles is realized through the cyclone dust removal cylinder. Since during the cutting operation a large amount of dust is generated, including during the strong wind suction, sand, larger branch debris and the like are also sucked in, and these larger, heavier particles are effectively decomposed with the air under the cyclone principle and are collected in the dust collecting bucket 9.
The buoyancy collecting barrel comprises a conical barrel 13, the periphery of the bottom of the conical barrel 13 is of a chamfer structure, and the barrel is a cone with a large-amplitude enlarged bottom small top sectional area.
