The utility model in order to overcome the problems referred above, provides a kind of hand-driven maize sheller, simple in structure, can pass through hand
Flowing mode carries out threshing to corn, meets the threshing demand of small yield corn.
The hand-driven maize sheller of the utility model, technical solution used for the above purpose are：Including setting
In sheller unit, positioning device and undertaking case on desktop, the sheller unit includes bearing inner race and bearing outer ring, the axis
The inner surface for holding inner ring is equipped with threshing nail and goes out a slot, and bearing inner race drop-over at outer ledge has the crank of Z-shaped, the axis
The connecting rod sliding that bearing outer-ring is equipped with by its bottom end is set on desktop；The positioning device includes positioning jackscrew, upper locating piece
And lower locating piece, the bottom surface of the upper locating piece offer semicircular upper locating slot, the top surface of the lower locating piece offers
Semicircular lower locating slot, the upper locating slot and lower locating slot are corresponding up and down, and shape after upper locating slot and lower locating slot closure
At annulus it is corresponding with bearing inner race level, upper locating piece is fixed on by spring on top plate, position jackscrew bottom end pass through top
The top surface of locating piece is withstood on after plate, the top plate is fixed on by column on desktop, and discharge port, institute are offered on the desktop
It states and accepts the lower section that case is positioned over discharge port.
The threshing oncomelania rotation is arranged in bearing inner race as a further improvement of the utility model,.So set, can
The threshing efficiency of threshing nail is effectively improved, while can prevent niblet from blocking.
The desktop is equipped with sliding rail as a further improvement of the utility model, and the bottom end of the connecting rod passes through cunning
Block is set on sliding rail.So set, sheller unit is made to move to make in corn insertion bearing inner race on desktop along sliding rail.
The utility model has the beneficial effects that：The utility model is arranged by bearing outer ring, bearing inner race and bearing inner race
The sheller unit for constituting corn is followed closely in threshing, and the positioning device of corn is constituted by positioning jackscrew, upper locating piece and lower locating piece,
Sheller unit sliding is set on desktop, makes sheller unit that can be moved to by the fixed corn of positioning device, to make corn insert
Enter in bearing inner race, then so that the nail of the threshing in bearing inner race is carried out threshing operations, the corn taken off to corn by rotating crank
It falls on to accept under grain is final automatic and carries out unified collection in case, to realize the purpose for carrying out manual threshing to corn, behaviour
Make simple and efficient, and convenient for carrying out unified collection to niblet, alleviates the amount of labour of peasant, it is time saving and energy saving.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of positioning device.
Specific implementation mode：
Referring to Figures 1 and 2, the hand-driven maize sheller of the utility model, include sheller unit 6 on desktop 19,
Positioning device and undertaking case 10, the sheller unit includes bearing inner race 4 and bearing outer ring 5, the inner surface of the bearing inner race 5
Equipped with threshing nail 3 and go out a slot 2, the drop-over at outer ledge of bearing inner race 5 has the crank 1 of Z-shaped, the bearing outer ring 5 logical
It crosses its bottom end and is equipped with connecting rod 7, the bottom end of the connecting rod 7 is set to by sliding block 8 on sliding rail 11.；The positioning device includes
Positioning jackscrew 14, upper locating piece 15 and lower locating piece 16, the bottom surface of the upper locating piece 15 offer semicircular upper locating slot
