Description

A kind of miniature seeding machine

Technical field

The present invention relates to a kind of sower, particularly a kind of sower for seeds such as sowing vegetable or flowers.

Background technology

Present miniature seeding machine on the market mainly comprises transmission mechanism and sowing mechanism, wherein sowing mechanism comprises suction kind of a head, mechanical arm, transmission device, seeding through hole and pressure-vaccum mechanism, mechanical arm drives first inhales kind of head to the position of seed pan, produce negative pressure by pressure-vaccum mechanism is air-breathing so that inhale kind of the suction nozzle place of head, so that inhale the suction nozzle that kind of head can be drawn onto vegetable or flower etc. kind from seed pan, then mechanical wall transmission mechanism drive lower swing so that inhale kind of head move to the seeding through hole above, inhale the top that the suction nozzle of planting head just in time is in the seeding through hole this moment, the transmission mechanism that cooperates is transferred to the breeding dish below of seeding through hole, make again pressure-vaccum mechanism become air-breathing into blowing to inhaling kind of the suction nozzle of head, the seed at suction nozzle place just is blown to the seeding through hole and enters on the breeding dish like this, present seeding machinary has labour intensity low, high efficiency, sow the advantages such as accurate, effectively avoid the seed waste, reduce production costs; But the motion that this sower realizes inhaling kind of head owing to the mode that adopts transmission mechanism and mechanical arm to cooperate, complicated structure, speed is relatively slow; Also in the breeding dish, beat when seed is blown to the breeding dish in addition or roll, cause the sowing position even or inaccurate, have influence on the cultivation in later stage.

Summary of the invention

Order of the present invention is the defective for existing sower, a kind of miniature seeding machine is provided, this miniature seeding machine will drive by the mode that cylinder and guide rail cooperate that to inhale kind of head mobile, set up simultaneously the up and down motion lane device of sowing, and have simple in structure, accurate efficient characteristics.

For achieving the above object by the following technical solutions:
