Before work, the second basket strainer is wound, being provided in the two sides of the second basket strainer makes the second dedusting upwards under the action of shutter
Net keeps the holding tank of vertical state, and then impeller rotates forward, and wind is entered in shell from air inlet and is then discharged by air outlet,
The forward and reverse of impeller at this time elaborate later.During the work time it should be noted that the telescopic shaft of hydraulic cylinder
In contraction state, roller is located at bottom, and wind enters in dust cleaning case from the side far from air inlet, then passes through air inlet
It enters in cabinet, is discharged finally by air outlet, willow catkins flying in the air are blocked in the side of the separate air inlet of the first basket strainer, are flying
After wadding accumulation to a certain extent, first controlling shutter moves down the second basket strainer, and the second basket strainer is made to be in unfolded state,
Then it is inverted by blower, so that air is entered cabinet from air outlet and then is passed through air inlet and enter in dust cleaning case, make first
Willow catkins flying in the air on basket strainer are detached from the first basket strainer, and the willow catkins flying in the air a part being detached from from the first basket strainer enters the second basket strainer
On, then by control hydraulic cylinder works, makes the telescopic shaft of hydraulic cylinder is flexible roller is driven to move up and down in backplate, be set in
Hairbrush outside roller handles the willow catkins flying in the air of the first basket strainer and the second dedusting net surface, and willow catkins flying in the air are fallen on collection device,
The hinge door for being collected to the willow catkins flying in the air in collection is offered at collection device, to the first basket strainer and the second dedusting
After online willow catkins flying in the air are handled, roller is reduced to bottom, and shutter carries out the second basket strainer to roll storage, and motor rotates forward
Carry out exhausting air inducing.
The flabellum of the utility model is set in the surrounding of shaft, and the making material of flabellum is well known PP material or AS material
Inclination angle Deng, each flabellum is apparent to describe the utility model by being consistent clockwise or counterclockwise, by the first limit
Position block is located in the first limiting slot, while the second limited block is located in the 4th limiting slot, and the inclined direction of all flabellums is along up time
Needle is consistent counterclockwise, and the state of impeller is suitble to rotate forward；When the first limited block is located in the second limiting slot, while the second limit
Position block is located in third limiting slot, and the inclined direction edge of all flabellums is consistent clockwise or counterclockwise, at this time the shape of impeller
State is suitble to invert.When needing to be from the suitable state for rotating forward and adjusting to suitable reversion by impeller, the first limited block is limited from first
It is moved in the second limiting slot in the slot of position, the second limited block is moved in third limiting slot out of the 4th limiting slot.Starting to adjust
Before section, it should be noted that third limited block is located in the 5th limiting slot, and connecting shaft keeps opposing stationary with connecting plate, that is, connects
Spindle will not relatively rotate with connecting plate, and the first link block is that gap is connect with the connection of the second link block and connecting plate,
That is the first link block can relatively rotate with the second link block, and the spring in connecting shaft is in compressive state, but spring
It can also be compressed at this time, spring leans on paracentral power to connecting plate one.When starting to adjust: applying one separate turn on flabellum
The power of axis center can manually directly be exerted a force with hand, by spring-compressed, the mobile spacing in the direction of connecting plate to separate spindle central
From making the first limited block be detached from the first limiting slot, the second limited block is detached from the 4th limiting slot and third limited block and is detached from the 5th
Then limiting slot keeps the external force on flabellum constant, rotate flabellum, move down the first limited block by first sliding groove, while the
Two limited blocks move up, and the first limited block reaches the position of the second limiting slot, and the second limited block reaches the position of third limiting slot, removes
The power being applied on flabellum is sold, under the elastic force effect of spring, the first limited block is pushed to enter in the second limiting slot, the second limit
Position block enters in third limiting slot, and third limited block enters in the 5th limiting slot, similarly, by all flabellums through above-mentioned
Impeller can be realized from the suitable transition for just going to and being suitble to invert in operation.
The beneficial effects of the utility model are as follows:
1, dust-extraction unit is able to achieve flexible disassembly, meets use in usual cases, while being also able to satisfy numerous in willow catkins flying in the air
It also can be carried out good work in the environment of weight.
2, the utility model is by adjusting the angle of connecting plate, and then realizes the angular adjustment to flabellum, keeps flabellum positive
It is changed to the back side of flabellum is facing forward forward, forward and reverse can be met simultaneously by realizing same blower, adapt to changeable work
Environment keeps the adaptability of blower wider.
3, cross sectional shape is provided in connecting shaft for the third limited block of regular polygon, in the impeller course of work, by flabellum
A part of power of transmitting is transmitted to third limited block, guarantees that the first limited block will not occur during the work time and be detached from first for flabellum
The case where limiting slot, the second limited block is detached from four limiting slots and the case where cause connecting plate arbitrarily to rotate.
4, the first basket strainer and the second basket strainer can be realized the self-cleaning to willow catkins flying in the air, utilize blower reversion and hydraulic cylinder
Effect realize timely cleaning to the first basket strainer.
