The fertile precision planter of multilayer deep placement
Technical field
The utility model relates to a kind of agricultural machinery, a kind of specifically fertile precision planter of multilayer deep placement that is used for dry land grain, beans plantation.
Background technology
China " three Norths " agricultural district, 10 years nine spring drought.According to agriculture requirement, which floor fertilizer preferably divides come deep placement.Like this, can save fertilizer amount, can guarantee crop again in process of growth, obtain enough nutrition.On the existing single body seeder, a fertilizer apparatus that all adopts a power transmission shaft to drive on the fertilizing box carries out work, and its shortcoming is because fertilising does not have the layering deep placement, has caused the waste of a large amount of fertilizer.
The external at present fertilizing method that adopts usually is to apply comprehensively, the whole layer placement of fertilizer method, and this is because its weather is more moistening, and the reason that fertilizer price is relatively cheap, the shortcoming of this kind method are that fertilizer application amount is big, and environment is had pollution, is not suitable for China rural area and uses.External sower, its sowing and fertilising part connect mutually with frame respectively, form an overall structure, because scale of operation is bigger, generally be to adopt big-powered tractor, drive multirow monoblock type sower and carry out operation, and China " three Norths " dry land area, production scale is less, power also has a small part animal power to drive operation again based on medium and small tractor, and external like this sower is not suitable for China " three Norths " dry land area and uses.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, volume is little, function is complete, can be neatly with the different dynamic combination, in sowing, also can realize the fertile precision planter of multilayer deep placement of the fertile function of multilayer deep placement.
The purpose of this utility model is to realize like this, this combined seed and fertilizer drill comprises front rack, four-bar mechanism, fertilizer distributor, whole frame, dispenser, grass stick, the multilayer deep-fertilizing furrow opener, the seeding and fertilizing plough, driving wheel, the soil covering implement that has position-limit mechanism, play mamoty, its four-bar mechanism is arranged on an end of whole frame, front rack is connected the front end of four-bar mechanism, grass stick is installed on the front rack, fertilizer distributor and dispenser be separately positioned on whole frame above, fertilizer distributor is provided with fertilizer apparatus, dispenser is provided with seeding unit, the multilayer deep-fertilizing furrow opener that has had mamoty and fertilizer outlet is arranged on the front lower place of whole frame, the seeding and fertilizing plough be arranged on seeding unit below, driving wheel and the soil covering implement that has a long ring jackscrew mechanism be arranged on whole frame the rear end.
Be provided with fertilizer apparatus below the described fertilizer distributor, fertilizer apparatus is the fertilizer apparatus of coarse thread scroll casing shape inwall, and its fertilizer valve is the step-less adjustment formula.
Two fertilizer apparatuss are set on the power transmission shaft below the described fertilizer distributor.
Be provided with seeding unit below the described dispenser, the seed wheel in the seeding unit is provided with the seed-filling hole of taper type at the bottom of the bead, and seeding unit is provided with the cantilevered feed shaft by single bearings.
Described multilayer deep-fertilizing furrow opener and seeding and fertilizing plough are the structure of double inclined plane formula, and the two position of staggering mutually is not provided with on same straight line.
The following rear portion of described multilayer deep-fertilizing furrow opener has the fertilizer outlet of several stepped settings, and the bottom also can install mamoty additional.
The position-limit mechanism that is provided with on the described soil covering implement is to adopt the long jackscrew mechanism that encircles.
The utility model is owing to adopt said structure to have the following advantages:
1, the utility model has been owing to adopted inwall to be the fertilizer apparatus of " spiral case " shape structure, makes the passage of fertilizer smooth, unobstructed, and the frictional resistance of fertilizer and defertilizing box wall is little; Its fertilizer valve by handle control, can infinitely change the size of defertilizing opening, and it is big to have the fertilizing amount excursion, and working resistance is little, following fertile advantage of uniform.
2, the utility model adopts two fertilizer apparatuss that driven on the fertilizing box by a power transmission shaft to carry out work, rely on two governor motions respectively the fertilizing amount of two fertilizer apparatuss infinitely to be regulated, be used for finishing the work of executing two kinds of fertilizer, it is simple in structure, and result of use is good.Carry out the drawback that work can not realize the layering deep placement at a fertilizer apparatus that drives on the fertilizing box with a power transmission shaft on the single body seeder before having overcome.
3, the utility model is a kind of monomer-type sower, so its structure is little, function is complete, can combine with different dynamic neatly, form single, double, four, six .... the row form carry out operation.Be fit to China " three Norths " dry land area, production scale is less, and power is based on the production actual conditions of medium and small tractor.
4, the utility model initiative is carried out multilayer deep placement fertilizer in sowing, on the multilayer deep-fertilizing furrow opener, leaves the fertilizer outlet of several stepped distributions, finishes the fertile work of multilayer " base fertilizer " deep placement; Use the seeding and fertilizing plough, only execute one deck " seed manure ".
