Embodiment
To describe the technology contents of the utility model, the objects and the effects in detail, below in conjunction with embodiment and match somebody with somebody
Attached drawing is closed to be explained.
The design of the utility model most critical is:The monoseeding of seed is realized using ratchet mechanism principle, to improve
Efficiency is sowed, saves manpower labour.
The utility model provides a kind of single seed seeder, including housing and ratchet mechanism；
The housing includes sequentially connected storage silo housing, middle casing and grain export housing；The storage silo housing,
Middle casing and grain export housing form interconnected cavity；The ratchet mechanism is installed in the middle casing；
The ratchet mechanism includes ratchet mechanism axis, spring, ratchet circle, ratchet spacing collar, thumb wheel and button；The ratchet
Mechanism shaft includes base and the hollow shaft being vertically fixed on the base, and the base is embedded in the middle casing side, institute
Spring, ratchet circle, ratchet spacing collar, thumb wheel and button is stated to be sequentially sleeved in the hollow shaft；
The upper surface of the base is close in the bottom of the spring, and the ratchet circle is close in the upper end of the spring
The ratchet spacing collar is close in lower surface, the upper surface of the ratchet circle, and the ratchet spacing collar is fixed on the hollow shaft
On, the thumb wheel is set on the ratchet circle；The outer wall of the thumb wheel is equipped with limit grain groove；
The button includes shell and the axis extended from cavity pocket of outer cover；The button is inserted in institute by the axis
State in hollow shaft；For the opening edge of the shell along " W " type wave tooth is equipped with, the upper surface of the ratchet circle is equipped with the first sawtooth,
" W " the type wave tooth is clamped with first sawtooth；The axis side is equipped with the first convex bank, the hollow shaft be equipped with
The first groove that the first convex bank is adapted；
The radius of the base is more than the spring ring outside diameter of the spring and the internal diameter of the thumb wheel, the ratchet circle it is outer
Footpath is more than the outside diameter of the ratchet spacing collar and the outside diameter of the button, the spring ring internal diameter of the spring and the ratchet circle
The outside diameter of the hollow shaft is equal to the internal diameter of ratchet spacing collar.
As can be seen from the above description, the beneficial effects of the utility model are：
Convex bank on button axis coordinates with the first groove on ratchet mechanism axis, limits the circular motion of button, makes
Obtaining button can only move up and down along ratchet mechanism axis；After pressing button, " W " type wave tooth promotes ratchet circle to transport downwards on button
Dynamic, since " W " type wave tooth is clamped with the first sawtooth on ratchet circle on button, thus ratchet circle is during moving downward
The active force that " W " type wave tooth can be subject on button to apply, the component of the active force along ratchet circle circumferencial direction have ratchet circle
There is the trend to rotate in a circumferential direction；After release button, under the action of springback power, ratchet circle promoting button is up moved, until
First sawtooth of ratchet circle is contacted with ratchet spacing collar, and " W " type wave tooth no longer acts power to ratchet circle on button, at this time
Ratchet circle, which is taken advantage of a situation, drives thumb wheel to have rotated a sawtooth cycle, and in the process, peanut grain enters the limit grain of impeller from storage warehouse
Groove, is discharged in input kind hole by the multiple grain export that rotates into, and from grain export.The seeder is realized using ratchet mechanism
The intermittent movement of thumb wheel, so that seed one one is put into the kind hole of field, greatly improves sowing efficiency, saves people
Power labour.
Further, the outer wall of the hollow shaft is equipped with up-small and down-big triangle limit fastener, and the ratchet is spacing
The inner wall of circle is equipped with the limit card slot being adapted with the limit fastener.
As can be seen from the above description, ratchet spacing collar is fixed on ratchet mechanism axis by the cooperation of limit fastener and limit card slot
On, limit fastener is designed to triangle so that ratchet spacing collar easily assembles not easy to remove, which avoids due to spring
Bounce-back and ratchet circle and ratchet spacing collar are ejected into ratchet mechanism axis.
Further, the ratchet spacing collar lower surface is equipped with the second sawtooth, second sawtooth and first sawtooth
Engagement.
As can be seen from the above description, the second sawtooth on ratchet spacing collar is engaged with the first sawtooth on ratchet circle, preferably
Ratchet circle is carried out spacing.
Further, the second groove is arranged with the outer wall of the ratchet circle, the inner wall of the thumb wheel is equipped with and institute
State the second convex bank that the second groove is adapted.
As can be seen from the above description, the cooperation of the second groove and the second convex bank is passed through so that when ratchet circle rotates, thumb wheel is the
Also and then rotated under the drive of two grooves, so that seed is transmitted to grain export from storage silo.
Further, the number of the limit grain groove is identical with the number of first sawtooth；The one of the limit grain channel opening
Side is fillet, and another side is wedge angle, and rotation direction of the wedge angle on the thumb wheel is with first sawtooth on ratchet
Rotation direction is identical.
As can be seen from the above description, when limiting the structure of grain groove and make it that ratchet circle drives thumb wheel rotation, only single seed every time
Enter from storage silo in limit grain groove；The number for limiting grain groove is identical with the number of the first sawtooth and rotation direction on ratchet circle so that often presses
Button next time, has a seed to enter grain export from limit grain groove, realizes efficient sowing.
Further, the single seed seeder further includes case lid, and the case lid is covered in the storage silo shell
