Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment：With reference to figure 1, a kind of corn drill, including body 1, is fixedly connected with kind of hopper 2, kind material on body 1
Case 2 is used to store corn seed.
With reference to figure 1, the front end of body 1 is rotatably connected to scroll wheel 3, and the lower end of body 1 is fixedly connected with colter 4, colter 4
The rear end of scroll wheel 3 is arranged on, colter 4 is used to plow groove on soil.With reference to figure 5, the lower end of body 1 is equipped with sowing mechanism
5, sowing mechanism 5 includes the fixed cylinder 6 being fixedly connected with 1 lower end of body, the rotary cylinder 7 being rotatablely connected with fixed cylinder 6, rotary cylinder
7 be hollow column casing, and rotary cylinder 7 is coaxially connected with rotation axis 8, and rotation axis 8 is rotatablely connected with body 1.With reference to figure 4, seeder
Linkage mechanism 25 is equipped between structure 5 and scroll wheel 3, linkage mechanism 25 includes and coaxially connected first gear 10 on the axis of rolling 9（Ginseng
Examine Fig. 3）, with rotation axis 8 it is coaxially connected have second gear 11, be arranged with chain between first gear 10 and second gear 11
12, first gear 10 and second gear 11 are realized by 12 bridle joint of chain and linked.
With reference to figure 4, the lower end of kind hopper 2 is equipped with sowing opening 13, and fixed cylinder 6 is set on the barrel of the side of kind hopper 2
There is the entrance 14 connected with sowing opening 13, offer outlet 15 immediately below fixed cylinder 6, the barrel of rotary cylinder 7 is equipped with some leak
16, the leak 16 of rotary cylinder 7 is rotated with the rotation of rotary cylinder 7, the entrance of the leak 16 of rotary cylinder 7 constantly with fixed cylinder 6
14 connect and stagger.As rotary cylinder 7 rotates, the leak 16 on the barrel of rotary cylinder 7 exists with the entrance 14 of fixed cylinder 6 to be overlapped
Area, the reason for so setting is that the leak 16 for preventing rotary cylinder 7 can not connect the situation of entrance 14；Meanwhile rotate
Arc length between 7 adjacent leak 16 of cylinder, the arc length intersected more than entrance 14 with fixed cylinder 6, in addition, the adjacent leak 16 of rotary cylinder 7
Between arc length, be that of avoiding more than the reason for 15 arc length for intersecting with fixed cylinder 6 of outlet, so setting and rotary cylinder 7 occur
Barrel can not shelter from the entrance 14 of fixed cylinder 6 and the situation of outlet 15.Due to the axis of rolling 9（With reference to figure 3）Passed by chain 12
Turn moving axis 8, the gearratio between the axis of rolling 9 and rotation axis 8 is constant, therefore the spacing sowed is identical, improves the uniform of sowing
Degree.
With reference to figure 4, hollow pipe 17 is fixedly connected with the outlet 15 of fixed cylinder 6, hollow pipe 17 is to leaking out from outlet 15
The sliding stroke of seed is oriented to, and is made seed as hollow pipe 17 slides and is dropped into colter 4（With reference to figure 1）The groove outputed
In.
With reference to figure 4 and Fig. 5, plant and adjustment sheet 18 is removably connected with the sowing opening 13 of hopper 2, adjustment sheet 18 is included at least
The rotatable lamella 19 that two panels rotates coaxially, is rotatably connected to rotation axis 26 between rotatable lamella 19, if being equipped with per a piece of rotatable lamella 19
Dry through hole 20, between two rotatable lamellas 19 when rotating any angle, the through hole 20 on two rotatable lamellas 19 all has what is overlapped
The reason for area, so setting is the size for changing the seed fallen from adjustment sheet 19, so as to reach the effect of screening seed.
With reference to figure 1, the lower end of body 1, which is extended with, fills out ditch plate 21, fill out ditch plate 21 be used for will the seed that sow in groove into
Row is buried, and seed is bonded with soil, so as to improve the bud ratio of seed.The rear end that ditch plate 21 is arranged on sowing mechanism 5 is filled out, is joined
The reason for examining Fig. 2, fill out ditch plate 21 and collinearly set along direction of advance with aforementioned hollow pipe 17 and colter 4, so setting is with machine
The advance of body 1, soil can be pushed into the groove that colter 4 is outputed by filling out ditch plate 21, so that soil is bonded with seed.
With reference to figure 1,1 lower end of body is rotatably connected to rammed earth cylinder 24, and rammed earth cylinder 24 is rolled across from groove, and passes through its gravity
Gap between soil and seeds is compressed, so as to improve the bud ratio of seed.
With reference to figure 1, the rear end thereof of body 1 is connected with support wheel 22, and support wheel 22 is used to prop up the rear end of body 1
Support, the rear end of body 1 are equipped with handle 23, and handle 23 facilitates user of service and holds and promote body 1 to advance.
Action process：
User of service holds on handle 23 and promotes body 1 forward, and scroll wheel 3 and support wheel 22 support body 1 respectively
Front-end and back-end, as body 1 advances, the colter 4 of 1 front end of body contradicts ground and carries out ditching operation, and body 1, which drives, to be rolled
Wheel 3 rotates, and with the rotation of scroll wheel 3, the coaxially connected axis of rolling 9 of scroll wheel 3 rotates, and the first gear on the axis of rolling 9 is led to
Cross chain 12 to interlock with the rotation the second gear of axis 8, rotation axis 8 drives the rotary cylinder 7 for being coaxial therewith connection to rotate, on rotary cylinder 7
Leak 16 constantly connected with the rotation of rotary cylinder 7 with the entrance 14 of fixed cylinder 6, at this time plant hopper 2 in seed due to gravity
Effect and the entrance 14 of fixed cylinder 6 is dropped into by sowing opening 13, as rotary cylinder 7 is rotated further, the leak 16 of rotary cylinder 7 with
The entrance 14 of fixed cylinder 6 connects, and seed is dropped down onto since gravity is dropped into rotary cylinder 7 by the leak 16 of rotary cylinder 7
The bottom of rotary cylinder 7.
With being rotated further for rotary cylinder 7, for seed due to the gravity of itself, seed is always positioned at the bottom of rotary cylinder 7
End.When the leak 16 on rotary cylinder 7 turns to the bottom of fixed cylinder 6, and the leak 16 on rotary cylinder 7 and fixed cylinder 6 go out
Mouthfuls 15 when connecting, and seed is dropped into by the leak 16 of rotary cylinder 7 in the outlet 15 of fixed cylinder 6, and from the outlet 15 of fixed cylinder 6
Dropping into the hollow pipe 17 being fixedly connected with the outlet of fixed cylinder 6 15, hollow pipe 17 is oriented to the stroke that falls of seed,
Hollow pipe 17 makes seed drop into the groove that colter 4 is outputed, and completes seeding operation.
User of service rotates the adjustment sheet 18 at sowing opening 13, is changed thereby using personnel on two rotatable lamellas 19
The overlapping area of through hole 20, so that the difficulty or ease journey for the through hole 20 that the seed for changing 18 upper end of adjustment sheet passes through two rotatable lamellas 19
Degree, so as to reach the size for changing the seed fallen from kind of hopper 2, so as to screen out the seed of some variations.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability
Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but
As long as all protected in the right of the utility model be subject to Patent Law.
