Abstract
The utility model relates to a plug seedling precision seeder for oilseed rape, which aims to effectively improve the seeding efficiency and the seeding quality. The plug seedling precision seeder for oilseed rape comprises a seeding head (2), a seed disc (13) and a reciprocating device which drives the seeding head (2) to be changed in position between a seeding station and a seed absorbing station above the seed disc (13). The seeder further comprises a stepping conveying device below the seeding station. The stepping conveying device consists of a baffle conveyer belt (1) and a stepping motor (9) installed on a roller set. The stepping motor (9) drives a driving roller in the roller set through a tooth-shaped synchronous belt.
Description
Technical field
The utility model relates to agricultural machinery, particularly a kind of rape plug-seedling precision seed planter.
Background technology
Compare with traditional seedling raising manners, point disk seedling growing has the advantage of following several aspects, and sowing quantity is few, and floor space is little, and can guarantee varietal purity; While growing seedlings, matrix used is without pathogen and insect etc.; Can guarantee to emerge rapidly, healthy and strong growth; Full root field planting, without slow seedling.Point disk seedling growing is widely applied in agricultural production.
Rape plug-seedling precision seed planter is broadly divided into two classes, i.e. single needle tubing (or sucker) formula sower and whole disc type pneumatic seeder.Single needle tubing (or sucker) formula sower can only be broadcast a row at every turn, has the inefficient deficiency of sowing.And the seeding head of existing whole disc type pneumatic seeder and the handover of seedling culture hole plate are all by completing manually, there is operation labour intensity greatly and the low deficiency of production efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rape plug-seedling precision seed planter, effectively to improve sowing efficiency and seeding quality.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Rape plug-seedling precision seed planter of the present utility model, comprise seeding head, seed dish and drive seed dish at the reciprocating moving device of inhaling dislocation between kind of station above sowing station and seed dish, it is characterized in that: it also has the step delivering device that is arranged at sowing station below, this step delivering device is made up of the baffle conveyer belt and the stepper motor that are installed in cylinder group, and stepper motor is by the drive roll in flute profile Timing Belt groups of drive rolls.
The beneficial effects of the utility model are, once complete many caves of whole dish seed and play, and sowing efficiency is higher, 7～8 dishes of broadcasting per minute; Cave dish drives baffle conveyer belt automatically to complete in a stepwise manner to completing station by stepper motor from station to be broadcast to sowing station again, and automaticity is high, reliable operation.
Accompanying drawing explanation
This specification comprises following three width accompanying drawings:
Fig. 1 is the left view of the utility model rape plug-seedling precision seed planter;
Fig. 2 is the local enlarged diagram of the seeding head in the utility model rape plug-seedling precision seed planter;
Fig. 3 is the front view of the utility model rape plug-seedling precision seed planter
The title of parts shown in figure and corresponding mark: baffle conveyer belt 1, seeding head 2, eccentric disc 3, reducing motor 4, first connecting rod 5a, second connecting rod 5b, rocking arm 6, gas distributing chamber 7, suction nozzle 8, stepper motor 9, air pump 10, electric-air valve 11, shock electric machine 12, seed dish 13.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1 and Fig. 3, rape plug-seedling precision seed planter of the present utility model, comprise seeding head 2, seed dish 13 and drive seed dish 13 at the reciprocating moving device of inhaling dislocation between kind of station above sowing station and seed dish 13, it also has the step delivering device that is arranged at sowing station below, this step delivering device is made up of the baffle conveyer belt 1 and the stepper motor 9 that are installed in cylinder group, and stepper motor 9 is in transmission connection by the drive roll in transmission mechanism and cylinder group.Cave dish drives baffle conveyer belt automatically to complete in a stepwise manner to completing station by stepper motor from station to be broadcast to sowing station again, and automaticity is high, reliable operation.
See figures.1.and.2, described seeding head 2 bottom surfaces dispose the suction nozzle 8 corresponding with the upper breeding of dish acupuncture point, cave, once complete many caves of whole dish seed and play, and sowing efficiency is higher, 7～8 dishes of broadcasting per minute.In seeding head 2, be provided with gas distributing chamber 7, gas distributing chamber's 7 inlet ends are connected with air pump 10 by tracheae 14, electric-air valve 11.Suction kind, the broadcasting kind of seeding head 2 are opened and closed and are realized by the electric-air valve 11 in air pump suction line, move accurately and reliably.By optimizing air passage structure, make the every cave of seeding head 2 only broadcast one, realize precision drilling, whole dish simple grain rate is more than 97%, and leakage sowing rate is less than 3%.
With reference to Fig. 1, described reciprocating moving device comprises the crank and rocker mechanism being made up of eccentric disc 3, first connecting rod 5a, rocking arm 6 and second connecting rod 5b, and the reducing motor 4 that drives eccentric disc 3 to rotate, and the lower end of second connecting rod 5b and seeding head 2 are in transmission connection.Seeding head 2 suctions are planted, two stations of sowing are completed automatically by this mechanism, and mechanization degree is high.
With reference to Fig. 1, described seed dish 13 is installed in frame by elastic base, and its bottom is provided with shock electric machine 12.Seed dish 13, under the effect of shock electric machine 12, vibrates in suspended state seed, is convenient to seeding head 2 and inhales and plant rapidly, has shortened and has inhaled kind of a time, has improved production efficiency.
Reciprocating moving device in the utility model, the action of step delivering device, the vibration of seed dish 13 is fed and is planted, and seeding head 2 suctions are planted, sowing action can be all by Programmable Logic Controller (PLC) programme-control, and intelligent degree is high.
Some principles of the above the utility model rape plug-seedling precision seed planter that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
