Description

A kind of cereal collects the screen device of machine
Technical field
Material collection, the equipment of packaging are carried out the present invention relates to a kind of utilization pneumatic means, a kind of paddy is specifically related to
Thing collects the screen device of machine.
Background technology
Publication No. CN204453878U patent document discloses a kind of harvester, including frame, engine, air blower, connecting tube, engine is connected with air blower, blower, it is characterized in that, materail tube is installed, one end of materail tube is connected by flexible pipe with inhaling valley head, and the other end of materail tube is connected by connecting tube with air blower in frame；The middle part bottom surface opening of materail tube is connected with material-falling hopper, the rear end of opening sets filter screen, the outlet of material-falling hopper is installed by changeover valve, power transmission shaft, roller and stirring vane are provided with changeover valve, stirring vane is fixed together with roller, and on power transmission shaft, power transmission shaft is connected by transmission belt with engine.Harvester in the technical scheme, engine blower, paddy is from valley head suction materail tube is inhaled, intercepted by filter screen, paddy falls into material-falling hopper and entered in changeover valve, under the promotion of stirring vane, exports and packs in changeover valve, the labor intensity of people can be substantially reduced, operating efficiency is significantly improved.But, the technical scheme remain main deficiency be carry out cereal collect operation when, the slightly long impurity being mingled with cereal, the thick piece impurity of such as bar stem, grass cuttings, pod shell, because can not constantly adsorb accumulation in filter screen side by screen meshes with air-flow, impurity can block sieve aperture increase air draught resistance, and air-flow weakens, cereal collection efficiency is reduced, living load increase；Disconnected whole gas channel can be blocked up in the case that impurity is slightly more so that cereal, which collects operation, can not proceed and stop.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides the screen device that a kind of cereal collects machine, can clear up screen compass screen surface impurity during operation repeatedly automatically, sieve aperture is not blocked, and good permeability, air-flow insertion is smooth, helps to reduce equipment power dissipation, improves cereal collection efficiency.
The technical solution adopted by the present invention is：A kind of cereal collects the screen device of machine, including the arc screen being installed in grain collecting barrel inner chamber, grain collecting barrel inner chamber is separated into negative pressure cavity and collection paddy chamber by screen, air suction mechanism connects negative pressure cavity, and negative-pressure air-suction is carried out to collection paddy chamber through screen, screen prevents cereal in collection paddy chamber from entering negative pressure cavity with air-flow, and reciprocal wiper back and forth is carried out to compass screen surface in arc screen by power-actuated wiper mechanism.
The grain collecting barrel, it is the part that cereal collects that progress air-flow is separated with cereal in machine, the cereal sucked at suction paddy mouth with air-flow enters in the collection paddy chamber of grain collecting barrel, screen prevents cereal in collection paddy chamber from entering negative pressure cavity with air-flow, and air-flow insertion screen sieve aperture enters negative pressure cavity, thus carry out air-flow and separated with cereal.Shred impurity in cereal can with air-flow through screen sieve aperture by air suction mechanism discharge machine outside, thick piece impurity can not be attracted to screen compass screen surface through screen sieve aperture, reciprocal wiper back and forth is carried out to compass screen surface in arc screen by power-actuated wiper mechanism, thick piece impurity is scraped off from screen compass screen surface, ensure that screen sieve aperture is not blocked, air-flow insertion screen remains smooth, it is ensured that the air draught lasts that front end is inhaled at paddy mouth are stable, help to reduce equipment power dissipation, improve cereal collection efficiency.
Above-mentioned wiper mechanism includes the brushing piece being arranged in rotating shaft, and rotating shaft end head installs swing arm, and swing arm is connected by connecting rod with by power-actuated eccentric stiffener.Described eccentric stiffener refers to common eccentric wheel, eccentric shaft；When eccentric stiffener is run, swing arm, rotating shaft is driven together to make reciprocal arc swing by connecting rod, the swing angle of brushing piece is general 180oWithin, brushing piece can carry out reciprocal wiper back and forth to the arc screen compass screen surface for swinging angular range, and cleaning impurity prevents sieve pore blockade.It is described swing angle refer to the corresponding central angle in arc swing path, be also two limit positionses radius between angle.
Above-mentioned wiper mechanism includes the brushing piece being arranged in rotating shaft, rotating shaft end head is installed by wheels, by wheels by the bigger transmission wheel drive of diameter, and drive is arranged on transmission shaft end head, swing arm is also installed, swing arm is connected by connecting rod with by power-actuated eccentric stiffener on power transmission shaft.Described eccentric stiffener refers to common eccentric wheel, eccentric shaft；When eccentric stiffener is run, swing arm, power transmission shaft, drive is driven together to make reciprocal arc swing by connecting rod, the angle of swing is general 180oWithin, drive is driven by belt or chain or the directly mode such as engagement and swung by wheels, in the case where drive is with diameter greater than stress wheel diameter, the swing angle of drive can be more than by being swung angle by wheels, through rotating shaft brushing piece is passed to by the swing of wheels, brushing piece equally swings the reciprocal arc swing of angle in company with stress crop rotation, and reciprocal wiper back and forth is carried out to the sieve bend compass screen surface for swinging angular range, and cleaning impurity prevents sieve pore blockade.Further technical scheme is that brushing piece makees circular arc reciprocally swinging, and it swings angle and is more than 180o, drive is set and by suitable diameter ratio between wheels, the swing angle of stress wheel can be made to be more than 180o, even up to 360o, brushing piece equally swings the reciprocal arc swing of angle in company with stress crop rotation, reciprocal wiper back and forth carried out to the sieve bend compass screen surface for swinging angular range, and cleaning impurity prevents sieve pore blockade.
The beneficial effect that the present invention is produced has：One is by setting arc screen in grain collecting barrel, screen compass screen surface is back and forth cleared up by power-actuated wiper mechanism, so that screen sieve aperture will not be blocked by impurity, sieve aperture good permeability, air-flow insertion is smooth, it ensure that paddy lasts stabilization is inhaled in front end, help to reduce equipment power dissipation, improve cereal collection efficiency；Two be that the circular arc reciprocally swinging angle being typically translated into is less than 180 when breaching in wiper mechanism using eccentric stiffener as power sourceoLimitation, by setting drive and by suitable diameter ratio between wheels, brushing piece make circular arc reciprocally swinging swing angle can be more than 180oAllow the radian of arc screen bigger than in conventional techniques, arc screen has more sieve apertures and bigger ventilative area, the resistance that air-flow insertion screen sieve aperture is subject to is less, and in the case of air suction mechanism air draught ability is constant, arc screen has more sieve apertures and bigger ventilative area, flow velocity during air-flow insertion screen sieve aperture can be made lower, rolling action to cereal is weaker, contribute to the cereal carried secretly in air-flow quickly to fall and be collected to Ji Gu bottom of chamber portion, cereal is fast with air-flow separating rate, can significantly improve cereal collection efficiency.
