Description
Technical field
This utility model relates to agricultural machinery technological field, is specially a kind of corn threshing device.
Background technology
At present for manual corn threshing, mostly using hand rubbing or the method for plank drag, not only waste time and energy, efficiency is low, destroys corn cob, the integrity of niblet, and the injury to staff is bigger.Although the machinery of existing corn threshing on market, but its structure mostly build is big, structure is complicated, complex operation, need professional to use, expensive, it is adaptable to the occasion of a large amount of corn threshings, and inapplicable for common peasant；How Semen Maydis after drying carries out quick threshing process is the most all a problem during rural area produces, traditional method needs to fully rely on manual operations, utilize simple instrument to be separated from corncob by dry niblet, and be processed further after niblet collection；The shortcoming of this method maximum is exactly that work efficiency is very low, and serious have impact on other normal agricultures of people business work.Along with the development of science and technology, in order to solve this problem, people have invented maize sheller.
Maize sheller is a kind of agricultural machinery equipment; it is mainly used to separate the niblet dried with corn cob; but existing maize sheller also has many Semen Maydiss ashes, skin of Semen Maydis and corn straw after there is corn threshing; all do not carry out impurity cleaning after threshing just to process; so that niblet exists the impurity of many, reduce the quality of niblet.
Utility model content
This utility model reduces the problem of niblet quality to there is much impurity after solving existing maize sheller threshing, and the purpose of this utility model is to provide a kind of corn threshing device that niblet after threshing can carry out impurity cleaning.
nullThis utility model offer base case is: corn threshing device，Including frame、Motor、Separating mechanism and pneumatic separator，Wherein，Described separating mechanism includes feed hopper、Threshing box and discharge pipe，Described threshing box is provided with charging aperture and discharging opening，Described feed hopper is positioned at above described threshing box，Described feed hopper is connected with described charging aperture，Described discharge pipe is positioned at below described threshing box，Described threshing box is provided with rotating shaft，The two ends of described rotating shaft are hinged on the inwall of described threshing box，Connect in described rotating shaft and have helical blade，Described helical blade is provided with threshing rod，The lower section of described rotating shaft is provided with waffle slab，One end of described waffle slab is connected on described threshing box inwall，Described threshing box is provided with outlet，The other end of described waffle slab is positioned at outside described threshing box through described outlet，Described motor is positioned at the side of described rotating shaft，The output shaft of described motor connects driving gear，One end of described rotating shaft connects the driven gear engaged with described driving gear，Described pneumatic separator includes blower fan and screening pipeline，Described blower fan is connected in described frame，Described blower fan is positioned at the side of described discharging opening，One end of described screening pipeline is connected with described discharging opening and the other end is connected with described discharge pipe，The sidewall of described screening pipeline is provided with sieve aperture.
nullThe operation principle of base case: start motor，Electric machine rotation，The output shaft rotation of motor，Driving gear rotates，The driven gear engaged with driving gear is driven to rotate，After axis of rotation，Pour the Semen Maydis treating threshing into feed hopper，Semen Maydis drops on waffle slab in charging aperture enters into threshing box，After rotating shaft rotates，Threshing rod motion on helical blade，Thus the Semen Maydis entered on waffle slab is clashed into，Niblet is separated with corncob，The niblet of threshing is gathered in discharge outlet and enters in screening pipeline drop to the bottom surface of threshing box from waffle slab after，Screening pipeline is blown by the blower fan of discharging opening side，Owing in Semen Maydis, the weight ratio niblet of impurity is little，Impurity in niblet stands after wind blows，From screening pipeline, drop away in the side away from blower fan，Remaining niblet continues to fall to discharge pipe，Thus complete the thrashing screen selection operation of Semen Maydis，Simultaneously，Corncob after threshing moves the last outlet from threshing box side along waffle slab under the effect of helical blade and sends.
Base case provides the benefit that: by arranging pneumatic separator below threshing box, screen the niblet after threshing, thus the impurity dispatch in niblet is gone out, and completes the screening to niblet, it is ensured that the quality of niblet after threshing.
Preferred version one: based on scheme preferred, described charging aperture is hinged with baffle plate, and described baffle plate is connected with the hinged place of described charging aperture sidewall and has elastic component；Beneficial effect: by arranging baffle plate at charging aperture, it is ensured that the one-way conduction at charging aperture, thus the niblet come off in avoiding threshing box splashes and hurts sb.'s feelings.
Preferred version two: preferably one preferred, described flexible member is spring；Beneficial effect: after spring is elected to be flexible member, has saved the cost of flexible member.
Preferred version three: preferably two preferred, the outside of described motor is provided with motor housing；Beneficial effect: after motor is arranged shell, it is to avoid motor is clashed into by the niblet that comes off in threshing box.
Excellent alternative four: preferably three preferred, the hinged place of described rotating shaft and described threshing box is provided with bearing；Beneficial effect: by arranging bearing in hinged place, reduces the abrasion that rotating shaft is subject to when rotating, thus extends the service life of rotating shaft.
