Abstract

The utility model discloses a mower with dust adsorption function, which comprises a shell with an engine and a rotary blade on the rotation shaft of the engine, wherein the bottom of the shell is provided with a cavity with a screw track on medial wall, the screw track is provided with an aggregate port communicated with a discharge opening at the tail of the shell via an air track in the shell, the rotary blade is arranged in the cavity, while the rotation shaft of the engine above the rotary blade is provided with a blade wheel. The utility model is characterized in that the cavity mouth of the cavity is covered by an air cavity cover with an air cavity hole, while the cover can improve the adsorption of the mower. The utility model can clean skull, leaf, and dust or the like, and effectively prevent large and rigid foreign materials from being absorbed, to protect internal elements.

Description

Mower with dust-absorbing function

Technical field

The utility model relates to a kind of mower with dust-absorbing function, specifically is to be provided with the cyclone collecting mechanism in a kind of casing, and the rotary cutter type mowers of using of strong adsorption capacity are arranged more.

Background technology

At present, common rotary cutter type mower structure comprises the casing that engine is set and is contained in the cutter that revolves on the engine shaft, described bottom of shell is the cavity that has the snail road on the madial wall, and snail has the mouth that gathers materials on the road, through the inner cyclone channel connection of casing casing afterbody discharge gate; Revolve cutter in cavity, also be provided with impeller on the engine shaft of its top.

The discharge gate that impeller on the engine shaft, madial wall have gas channel in gathering materials mouthful on the cavity, snail road in snail road, the casing and a casing afterbody constitutes cyclone of the present utility model mechanism simultaneously; Impeller on engine shaft when revolving cutter and rotate synchronously, blade in the impeller forces gas rotation in the cavity, gas is done work, its energy is increased, gas is under action of centrifugal force, around impeller, throw away, can convert speed to the pressure energy by vortex street, after the gas in the impeller is discharged, pressure in the impeller is lower than the cavity internal pressure, new gas is intake impeller under action of pressure, forms cyclone, and the weeds of being cut off mainly are to gather materials mouthful and discharged by casing afterbody discharge gate in company with cyclone centrifugal high speed rotating and entering in cavity snail road.

Though this type of mower has certain centrifugal adsorption capacity, bottom of shell cavity opening is bigger, cause less with the pressure reduction of impeller internal pressure herein, absorption affinity a little less than, only for being used for to cutting off the collection of weeds; Also do not see lawn or pavement garbages such as using it for absorption pericarp, leaf, dust at present, people can only clear up above-mentioned ground refuse with other device after mowing, very inconvenient; Also be because the bottom of shell cavity opening of this type of mower is too big in addition,, tend to suck some big and hard foreign material and collide with and revolve cutter, cause and revolve the cutter damage even block the mouth that gathers materials, bring great inconvenience to use if clear up ground refuse with it.

Summary of the invention

The utility model purpose is: a kind of mower with dust-absorbing function is provided, possesses stronger adsorption capacity, be suitable for clearing up ground refuses such as melon skin, leaf, dust, and can effectively prevent to suck some big and hard foreign material and cause part injury in the machine, enriched the mower purposes.

The technical solution of the utility model is: a kind of mower with dust-absorbing function, comprise the casing that engine is set and be contained in the cutter that revolves on the engine shaft, described bottom of shell is the cavity that has the snail road on the madial wall, snail has the mouth that gathers materials on the road, through casing internal gas flow channel connection casing afterbody discharge gate; Revolve cutter in cavity, also be provided with impeller on the engine shaft of its top; It is characterized in that being stamped on the accent of described bottom of shell cavity the air cavity lid of offering the air cavity hole.

Described air cavity covers and is provided with the bayonet fittings that trip is provided with bottom of shell cavity periphery, and perhaps the air cavity lid is threaded with bottom of shell, can certainly be other movable connection method.

The air cavity hole number that the utility model air cavity covers can be any, but even in order to guarantee air inlet, and suction is stable, must be identical about air cavity lid center symmetry and shape.

Some other technical characterictic on the utility model casing is the same with prior art, for example is fixed with hand-pushing handle on casing, and hand-pushing handle is provided with joystick; The casing afterbody is socketed with collecting bag, and discharge gate is communicated with the collection sack; Casing is provided with four wheels.

The utility model advantage is:

Air-breathing principle with centrifugal fan: after the openings get smaller of air inlet duct, cause supercharging air herein, strengthened pressure differential, thereby strengthened blower fan suction with the impeller internal pressure; Because the air cavity that the utility model covers covers and has less air cavity hole, compare with original bigger snail road cavity opening, obviously help improving absorption affinity, thereby can use it for ground refuses such as cleaning melon skin, leaf, dust; Simultaneously less air cavity hole can stop effectively that also these foreign material enter damage and revolve cutter or the obstruction mouth that gathers materials, the working life that helps to prolong it.Therefore the utility model has well enriched the purposes of common rotary cutter type mower.

Below in conjunction with drawings and Examples the utility model is further described:
