Technical solution：The sheller unit for corn ear both ends residual particles of the utility model, including base, the bottom Seat is equipped with separating mechanism, driving mechanism, the transmission mechanism between the separating mechanism and driving mechanism, the thresing machine Structure includes the recessed disk of threshing that inside offers tapered channel, and can be turned by the transmission mechanism under the action of driving mechanism It is dynamic, and the recessed disk inner surface of the threshing is vertically equipped with the cone of some sharp portions outwardly.

In order to ensure that the recessed disk of threshing can be rotated under the action of driving mechanism and is fixed on base, outside the recessed disk of threshing Surface is cylindrical, its outer peripheral edge is socketed with clutch shaft bearing, and the clutch shaft bearing outer ring is socketed with bearing block, the bearing block It is connected by first support bar with the base.

In order to ensure that the residual particles at corn ear both ends all come off, it is wide on the tapered channel, under it is narrow, enter mouth width so as to In corn ear being put into the recessed disk of threshing, outlet it is narrow in order to by the residual particles at corn ear both ends all in vertically disposed cone Come off under body effect.

Driving mechanism is rotatably fixed on base in order to realize, the driving mechanism includes intermeshing first Gear and second gear；First gear and the second gear inner ring is socketed with second bearing, and in each second bearing Circle is socketed with second support bar, and is connected by second support bar with base.

To prevent gear or the recessed disk of threshing stuck, the transmission mechanism includes length retractable and flexible connecting rod, described soft Disk recessed with threshing and second gear revolute pair are connected property connecting rod two end respectively；The flexible link includes two connecting rods and connection Elastic component between two connecting rods.

In order to facilitate rotate gear, the first gear is connected with the handle that can rotate it.

Gear accidentally injures user of service in order to prevent, and the driving mechanism is equipped with shell, and the shell passes through screw and base Connection.

For the ease of the corn ear in the pressing recessed disk of threshing, the recessed disk of taper threshing is equipped with matched dust-proof with its shape Lid, while prevent airborne dust.

Beneficial effect：1st, the utility model is simple in structure, practical；2nd, the device simple operation, Threshing are good；3rd, it is applicable in Used in small-scale farmer；4th, manual threshing is avoided, threshing efficiency is high, reduces labor intensity.

Embodiment

Referring to Fig. 1 to Fig. 5, the threshing for corn ear both ends residual particles described in one embodiment of the utility model fills Put, including base 1, separating mechanism 2, driving mechanism 3 and transmission mechanism 4 on base 1.

Separating mechanism 2 includes inside and offers the recessed disk 21 of threshing of tapered channel 211, and can be existed by transmission mechanism 4 Rotated under the action of driving mechanism 3；Equipped with dustproof cover 25 matched with its shape, the inner surface of the recessed disk 21 of threshing is vertically equipped with some The cone 22 of sharp portion outwardly, and tapered channel 211 enter mouth width, outlet it is narrow, outer surface is cylindrical, its outer peripheral edge is socketed with Clutch shaft bearing 23, and 23 outer ring of clutch shaft bearing is socketed with bearing block 24, bearing block 24 is connected by first support bar 5 with base 1.

Driving mechanism 3 includes intermeshing first gear 31 and second gear 32 and the shell 34 being provide with outside it, the One gear 31 is connected with the handle 35 that can rotate it；First gear 31 and 32 inner ring of second gear are socketed with second bearing 33, and 33 inner ring of each second bearing is socketed with second support bar 6, and be connected by second support bar 6 with base 1, shell 34 It is connected by screw 11 with base 1.

Transmission mechanism 4 includes length retractable and flexible connecting rod 41, and flexible link 41 includes two connecting rods 42 and is connected to Elastic component 43 between two connecting rods 42, elastic component 43 are bar-spring, 41 both ends of flexible link disk 21 recessed with threshing and respectively Two gears, 32 revolute pair connects.

The use step of the utility model is as follows：

The corn stick end that both ends are remained to particle enters from the import of the recessed disk 21 of threshing, and first is rotated by handle 35 Gear 31, so as to drive second gear 32 to rotate, and drives the recessed disk 21 of threshing to rotate, corn ear is in threshing by flexible link 41 Lower threshing is acted on by band sharp portion cone 22 in recessed disk 21, niblet is flowed out from the outlet of the recessed disk 21 of threshing, completes corn The threshing of stick end residual particles.
