Therefore, the thickness of the seed furrow earthing is relatively appropriate by arranging the tension springs 3-7, and the condition that the earthing thickness is too thick or too thin is effectively avoided.
The working process of the invention is as follows:
the miniature potato is contained in the seed box 7-1, the driving device 10 drives the travelling shafts of the travelling wheels 2 to rotate, the travelling shafts drive the two travelling wheels 2 to rotate, the whole miniature potato planter walks in the field under the auxiliary action of the rear wheels 4, the ditching plowshare 8-3 of the ditching device 8 is inserted into soil and moves forwards along with the whole miniature potato planter, a ditch is formed in the soil, soil turned up by the ditching plowshare 8-3 separates the soil to two sides of the ditch formed by the ditching plowshare 8-3 under the action of the ditching plates 8-11 and the ditching opening plate 8-4, and then a seed ditch with a certain depth and a certain width is formed. The walking shaft of the walking wheel 2 drives the speed regulator 6 to work through the chain wheel transmission mechanism, the speed regulator 6 adjusts the speed transmitted by the walking shaft and then drives the seed sowing shaft 7-3 to rotate through the chain wheel transmission mechanism, so that the seed sowing shaft 7-3 drives the movement speed of the chain spoon type seed sowing device 7-4 to be adjusted under the condition that the advancing speed of the miniature potato sowing machine is not changed, and the adjustment of the column pitch of the miniature potato sowing can be realized. The seed discharging shaft 7-3 drives the chain spoon type seed discharging device 7-4 to work in the rotating process, the seed spoon on the chain spoon type seed discharging device 7-4 is driven to rotate along with the chain discharging shaft in the seed discharging chain transmission process, the seed spoon takes seeds and then drives the seed discharging chain transmission, after the miniature potatoes are played in the seed ditch after the ditching device 8 is opened, the soil on the two sides of the seed ditch can be raked towards the seed ditch by the two soil covering discs 3-1 of the soil covering device 3, and the soil covers the miniature potatoes in the seed ditch; the miniature potato planter completes the whole processes of ditching, seeding and soil covering.
The miniature potato seeder adopts mechanical automatic seeding, ensures the seeding efficiency of miniature potatoes, and realizes no-missing seeding by a seeding mode of 'one ridge and one row'; meanwhile, the damage to the miniature potatoes in the sowing process is avoided, the damage rate of the miniature potatoes is reduced, the labor force is saved, and the economic loss of miniature potato farmers is reduced.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
