Embodiment 1

As shown in Figure 1 and Figure 2, a kind of seeder, including rack 1, sowing mechanism 2, furrowing blade 3, traveling wheel 4 and handrail 5, The traveling wheel 4 is rotatably connected in the rack 1, the rack 1 between the furrowing blade 3 and the handrail 5,

As shown in Figure 1 and Figure 2, the sowing mechanism 2 includes the plants case 6 being fixed in rack 1, is provided in the plants case 6 Sowing opening is rotatably connected to the feed shaft 7 for closing the sowing opening in the plants case 6, is further fixed on conveying in the rack 1 The discharging tube 8 for the seed that feed shaft 7 is discharged offers on the feed shaft 7 and accommodates seed and will in sowing shaft rotation process Seed is sent to the groove of discharging tube 8, and the feed shaft 7 is driven by 9 driving wheel 9 of driving wheel being fixed on the handrail 5 to be turned Dynamic, the driving wheel 9 drives feed shaft 7 to rotate by transmission chain 10；

As shown in Figure 1 and Figure 2, the furrowing blade 3 is slidably connected at by montant 11 in the rack 1, in the rack 1 Be provided with the through-hole for passing through montant 11, be arranged on the montant 11 push montant 11 move so that furrowing blade 3 remotely The elastic component 12 in face is provided with the locating piece 13 of positioning elastic part 12 in the one end of the montant 11 far from the furrowing blade 3, fixed Position block 13 can be an integral structure with montant 11, and the elastic component 12 is between the rack 1 and the locating piece 13, institute It states handrail 5 to be rotatably connected in the rack 1 by axis body 14, pressure montant 11 is provided on the handrail 5 so that trench digging Shovel 3 is inserted into the briquetting 15 on ground, and briquetting 15 can be a part for handrail 5, and briquetting 15 can also be welded on handrail 5；

As shown in Figure 1 and Figure 2, the backfill plate 16 of soil that backfill furrowing blade 3 is routed up, the row are provided in the rack 1 Seed is discharged between furrowing blade 3 and backfill plate 16 by kind pipe 8, and the backfill plate 16 is located at the driving wheel 9 and the furrowing blade 3 Between, also, the driving wheel 9 is compacted the soil that the backfill plate 16 backfills.

Plants case 6 can be bolted in rack 1, and backfill plate 16 can be welded in rack 1, can also pass through spiral shell Nail is fixed in rack 1, and the cross-sectional shape for backfilling plate 16 can be V-shape, and the soil that seed furrow both sides are routed up returns It is filled in seed furrow.

There are two states for the tool of handrail 5 in the present embodiment：

As shown in Figure 1, state one, seeder is in working condition, at this point, handrail 5 overcomes elastic component 12 using its dead weight Active force, pressure montant 11 make furrowing blade 3 be inserted into below ground, also, the driving wheel 9 being set on handrail 5 is contacted with ground, Operating personnel move seeder and are moved in field, and furrowing blade 3 excavates seed furrow, and sowing mechanism 2 will under the driving of driving wheel 9 Seed is uniformly sown into seed furrow, also, is backfilled plate 16 and the soil of seed furrow both sides is backfilled to seed furrow, and by driving wheel 9 Sowing is realized in the soil compression that will be backfilled in seed furrow.

As shown in Fig. 2, state two, in mobile status, seeder refers to operating personnel's correction in mobile status and broadcasts seeder Kind device position moves to seeder in field, and at this moment seeder is acted without sowing.In this state, operating personnel will help Hand 5 lifts certain angle, that is to say, that handrail 5 is made to rotate by a certain angle to the direction far from ground, handrail 5 rotates certain angle After degree, driving wheel 9 leaves ground, also, handrail 5 does not apply active force to montant 11, and montant 11 is under the action of elastic component 12 It moves up and lifts furrowing blade 3, in this case, driving wheel 9 and furrowing blade 3 do not contact with ground, operating personnel Easily move seeder.

The elastic acting force of elastic component 12 should be able to also be overcome under the premise of it can lift furrowing blade 3 by the dead weight of handrail 5, In favor of the use of seeder.

The seeder is suitable for small area field, and the seeder is by artificial traction.

Embodiment 2

The present embodiment introduces the type of drive of driving wheel 9.

As shown in Figure 1 and Figure 2, the driving wheel 9 is fixed on by connecting rod 17 on the handrail 5, and connecting rod 17 can weld It is connected on the handrail 5, the driving wheel 9 is rotatably connected on by drive shaft 18 in the connecting rod 17, the drive shaft 18 On be provided with the drive sprocket 19 coordinated with the transmission chain 10, drive sprocket 19 is rotated synchronously with drive shaft 18, drive sprocket 19 can by key connection be fixed in drive shaft 18, be provided on the feed shaft 7 coordinate with the transmission chain 10 it is driven Sprocket wheel 20, feed shaft 7 are rotated synchronously with driven sprocket 20, and driven sprocket 20 can be fixed on by key connection on feed shaft 7.

In a state that handrail 5 is lifted, transmission chain 10 might have certain loosening, and the loosening is mainly due to handrail Distance reduces between drive sprocket 19 and driven sprocket 20 after 5 rotations, still, since the rotation angle of handrail 5 is smaller, the pine It is dynamic to be not sufficient to that transmission chain 10 is made to be detached from drive sprocket 19 or driven sprocket 20, therefore, handrail 5 when lifting, putting down not It needs to ressemble transmission chain 10.

Embodiment 3

The present embodiment is the optimization to seeder.

As shown in Figure 1 and Figure 2, operating personnel are in mobile seeder, it may be necessary to mobile larger distance, during this It is to compare laboriously that operating personnel lift handrail 5 always, and therefore, handrail 5 should can be positioned after lifting, to reduce operator The labor intensity of member.

Riser 21 is fixed in the rack 1, riser 21 can be welded or be fixed by screws in the rack 1, institute State the positioning pin for being provided on riser 21 and the handrail 5 being positioned after handrail 5 lifts, offered on the handrail 5 with it is described fixed The pin hole 22 of position pin cooperation.

It is the positioning for realizing handrail 5 that positioning pin, which is inserted into pin hole 22, and the program reduces the labor intensity of operating personnel.

Embodiment 4

The present embodiment is the optimization to seeder.

Seeder should all be integrally steady in working condition or mobile status, i.e., seeder should be not easy to overturn.

The traveling wheel 4 at least there are three, the traveling wheel 4 is rotatably connected to by shaft 23 in the rack 1, turn Axis 23 can be welded in rack 1, and rolling bearing can be set between traveling wheel 4 and shaft 23.

Preferably, four traveling wheels 4 should be set in rack 1, to improve the stability of seeder.

Embodiment 5

The present embodiment is the optimization to seeder.Seeder handrail 5 in working condition can apply active force to montant 11, At this point, the depth that furrowing blade 3 is inserted into ground may be caused deeper, and it is unfavorable for sowing operation, therefore, reply furrowing blade 3 is inserted into The depth on ground is controlled, for example, in rack 1 set supporting armrests 5 structure, handrail 5 contacted with the structure after by this Structural support handrail 5, so as to which handrail 5 is avoided to continue to apply active force to montant 11.

As shown in Figure 1 and Figure 2, the screw rod 24 that limitation furrowing blade 3 is inserted into ground depth, institute are additionally provided in the rack 1 The screw hole for being provided in rack 1 and coordinating with the screw rod 24 is stated, is provided on the screw rod 24 and is contacted and support with the handrail 5 The supporting block 25 of the handrail 5, supporting block 25 are an integral structure with screw rod 24, and the cross-sectional shape of supporting block 25 can be with For polygon, in favor of operating personnel's rotary screw 24, the supporting block 25 is between the handrail 5 and the screw rod 24.

Embodiment 6

The present embodiment discloses a kind of structure of elastic component 12, but is not to limit, and elastic component 12 can also be produced by other Raw elastically-deformable structure substitutes.

The elastic component 12 is spring.

Spring is cheap, reduces the use cost of seeder.
