How with selection by winnowing and screening machine
The utility model relates to a kind of device that adopts air-flow or method for sieving that solid is separated from solid, especially a kind of many with selection by winnowing and screening machine.
At present, mainly can be divided into selection by winnowing or screen two big classes at the widely used solid separating device in industrial or agricultural field, they establish one's own system often, the independent use, and specific aim is extremely strong, can not take into account and use with.And pneumatic separation device uses morely on agricultural, and screening plant then mainly is used in industrial.In case of all will use the time, then often substep uses separately, so the narrow and small separator of these ranges of application can not adapt to the needs of modern production.Chinese patent CN2276840Y discloses a kind of " the assorted clearly stone unit mahine that goes of raw grain ", and its primary structure feature is sieve structure and following sieve structure to be housed on the frame, to be provided with the single shaft eccentric wheel therebetween.Stone remover, blower fan are equipped with in the bottom, and fan outlet is connected in selection by winnowing charging aperture place with pipeline, and it also is equipped with the charging elevator to feed.Though this unit mahine makes up selection by winnowing and sizing screening, strengthened function of use, but its complex structure, transmission of power distance, link are many, power consumption is higher, especially fixed mode design has brought bigger limitation and restriction to the scope of application and material, still can not satisfy a tractor serves several purposes, one-machine-multi-function, the changeable modern production requirement of combination.In addition, its material flow is long, and installation, maintenance is all inconvenient, more difficult moving, so efficient is lower, result of use is not ideal enough.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art part, propose a kind of simple in structure, body is little light, install and keep in repair easily, parts change flexibly in addition, move and the operation facility, selection by winnowing and screening combination ability are strong, multiple functional and adaptability is good, service efficiency height, good separating effect many with selection by winnowing and screening machine.
The purpose of this utility model reaches by implementing following technical proposal: be respectively equipped with feed hopper and blower fan on the top of support, the oscillatory type multilayer screening plant that tilts towards the discharging opening direction is settled in its underpart, is installed between feed hopper and the oscillatory type multilayer screening plant from the air channel that blower fan is drawn and extends laterally to the opposite side opening.Above-mentioned oscillatory type multilayer screening plant can be located on the bearing that is fixed on the support by the guide rail adjustable shelf of its both sides, is convenient to it and vibrates back and forth and dismantle; The installation of this guide rail is good with the screening plant reversed dip with inclination also, so that produce slight beating in vibration; Described oscillatory type multi-deck screen packing bottom set portion preferably is provided with front and rear baffle, is equipped with eccentric wheel therebetween, by its combination results porpoise; Provide the motor of power preferably to be located at the gap of feed hopper side lower part, and turn round by actuator drives blower fan and eccentric wheel respectively.
Accompanying drawing is the structural representation of the utility model embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.Be separately installed with feed hopper 2 and blower fan 3 on the top of support 1, its underpart is provided with the whole screening of the oscillatory type box 4 that tilts towards the discharging opening direction, top sieve sheet 5 wherein, sieves sheet 6 down and is divided into for respectively carrying left and right and bottom discharging opening three layers.Laterally draw air channel 7 from the air outlet of blower fan 3 and place between above-mentioned feed hopper 2 and the screening box 4 and horizontal expansion, be opened on an other side, wherein be provided with the air regulating board 8 of control air quantity and flow velocity.The both sides of described screening box 4 are fixed with the inclined guide rails opposite with itself incline direction 9, and support 1 corresponding section is fixed with bearing 10, come movable this screening box 4 of installing on the corresponding bearing 10 by guide rail 9 is set up in.The bottom of screening box 4 is welded with front and rear baffle 11, is provided with an eccentric wheel that is mated 12 therebetween, and it is connected on the support 1 by power transmission shaft and annex, and is driven by motor 13.Motor 13 is installed in feed hopper 2 side lower part gaps, and its output shaft is by actuator drives blower fan 3 runnings of band clutch.When practical operation and use the utility model product, can select its independent selection by winnowing according to different solid materials, screening or selection by winnowing and screening combination function also can select the screening box 4 of different apertures specification to be installed on the support 1 separately.Separately during selection by winnowing, only need dismounting screening box 4 to get final product; When screening separately, then only need the transmission clutch disconnection of blower fan 3 is got final product; When being used in combination, solid material be earlier through selection by winnowing after screening, and can control selection by winnowing intensity and select the screening specification, so that alleviate the load of screening.Through solid material that screenings at different levels are come out in the discharging opening category set of each layer, discharge.
The utility model has simple in structurely compared with prior art, and body is little light, install and easy to repair, Parts change flexibly in addition, and mobile and operation facility, strong adaptability, and multiple functional, the service efficiency height separates The characteristics such as effect is good are suitable for classification and the lock out operation of industrial and agricultural products or raw material.
