Description
Technical field
The utility model relates to the thresher of crops corn, is specifically related to a kind of LB hobbing-type husker sheller.
Background technology
Along with socioeconomic development; existing conventional agricultural tool is also towards mechanization, automation development; along with the continuous increase of the corn yield of people; corn threshing just becomes the problem of a pendulum in face of people, and artificial threshing is too slow, wastes time and energy; the appearance of husker sheller; solve the problems referred to above, reduce hand labor intensity, most importantly make operating efficiency high greatly.Existing corn threshing work is generally for shining the corn ear dried, its water content is up to 18%, moisture is high, seed and mandrel bonding strength large, cause threshing Quality Down, threshing percent of loss improves, and considers for the actual conditions of grower, being difficult to set up special drying chamber makes the moisture of corn ear reduce, and then seed breakage rate during reduction fruit ear threshing.Therefore, target is placed on the structure improvement aspect to husker sheller by researcher, to obtaining the less thresher of corn kernel breakage rate.
Utility model content
The purpose of this utility model is to provide a kind of LB hobbing-type husker sheller, when corn ear water content is higher, still can obtain the lower corn kernel of breakage rate.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of LB hobbing-type husker sheller, comprise frame, be fixed on the threshing bin in frame, be located at the feeding hopper on threshing bin input top and be located at the knockout bucket of threshing bin output end, be provided with threshing spindle in described threshing bin and be arranged on the threshing cylinder on threshing spindle, the belt pulley that the output shaft of motor is arranged by belt and threshing spindle one end is connected, on threshing spindle, one end of corresponding feeding hopper is provided with the plate tooth for the corn ear of feeding being advanced to threshing cylinder outer peripheral face, plate tooth is made up of two helical blades of the axial external surface spiral cross-distribution along threshing spindle, two helical blades are arranged around its crosspoint Central Symmetry, the outer peripheral face of described threshing cylinder is provided with the gear hobbing of many rows for threshing along its axial uniform intervals, each row's gear hobbing setting straggly makes its outer peripheral face along threshing cylinder in spiral distribution, described gear hobbing is the integrative-structure connected and composed by halfpace and arc teeth, the two sides be oppositely arranged in arc teeth are respectively inner concave arc surface and outer convex globoidal, the angle of the inner side edge place plane of the inner concave arc surface of arc teeth and the tangent line of halfpace connecting portion and halfpace is 150 ~ 160 °, and the angle formed between halfpace and arc teeth is towards the rotation direction of threshing cylinder.
Described frame be provided with to be positioned at below threshing bin and with the receipts grain device of its inner space, be provided with the vibratory sieve that arrange corresponding to the output of threshing cylinder in described knockout bucket, the below of vibratory sieve is provided with the seed slide plate extending into and receive grain device inside.
Further, annular notch board is provided with between threshing bin and threshing cylinder, the height often arranging each gear hobbing in gear hobbing is identical, corn ear can be squeezed between gear hobbing and annular notch board inwall by threshing by the rational height of gear hobbing, annular notch board is evenly provided with and falls to for sloughing seed the honeycomb hole received in grain device.
Further, threshing bin is provided with air exhauster with the connecting portion receiving grain device, and this air exhauster is used for foreign material such as being divested the maize head that is mingled with in seed to extract out and venting.
The top at described threshing bin two ends is equipped with semicircular baffle plate, the effect of baffle plate: one, the safety of safeguard work personnel, because when the normal threshing of thresher, threshing cylinder High Rotation Speed, if without baffle plate, may cause staff not very by hand or clothes heave in thresher, the accident such as to cause casualties occurs; Two, stop that the corn kernel after threshing splashes, because corn ear is by after threshing, the iblet splashes that the threshing cylinder of High Rotation Speed makes gear hobbing take off, the corn kernel after the setting of baffle plate can avoid threshing can not be all collected in grain device.
Beneficial effect: the gear hobbing 1, connected and composed by halfpace and arc teeth, angle between halfpace and arc teeth arranges and the structure simulation that whole gear hobbing is pecked according to chicken is formed, make gear hobbing when to corn ear threshing, debunching action can be played to corn kernel and corncob, and under the specific rotating speed of threshing cylinder, gear hobbing can not produce damaged effect to corn kernel, more effectively can carry out corn threshing work, reduce corn kernel breakage rate.
2, plate tooth threshing spindle being located at threshing cylinder input end can accelerate the feeding speed of corn ear, and the corn ear being convenient to feed can contact with threshing cylinder quickly, improves threshing efficiency.
