Abstract

The utility model relates to a seeder for seeding against stubble, which is used in the wheat field. The utility model is composed of an outer grooved wheel type fertilizing device hung on a machine frame, an inner-charging type vertical disc seeding device and a shovel blade type narrow furrow opener, wherein, the midsection of a main beam of the machine frame is only provided with an anti-slip land wheel, the fertilizer and the seeds are discharged by driving chains, and a stubble breaking fertilizing furrow opener and a seeding furrow opener form a lateral deviation from 1 cm to 3 cm. The furrow opener has the advantages of good earth breaking-into performance, narrow furrow, reliable seed discharging and high single seed rate. Thus, the utility model has the advantages of seed saving, good emergence of seedlings, reasonable structure, high intensity and light weight.

Description

Seeder for seeding against stubble

The utility model relates to the farmland seeding machinery, particularly a kind of combined seed and fertilizer drill.

Along with Agricultural Development, new requirement has also been proposed seeding machinery.In the toothing wheat field, pasting stubble sowing corn is a kind of operating type of striving farming season, obtaining high yield.But existing with 12 to 20 horsepowers of supporting seeding machineries owing to exist plough bad at hard stub land penetration performance, deep mixed the causing of ditch, the too wide easy evaporation of water in soil of kind ditch, influence is emerged; Kind, fertilizer are gone into the soil phase and are mixed with burning kind of a phenomenon; Problems such as the seeding unit parts are easy to wear, and the design of the low and complete machine structure of single seed rate is unreasonable still can not satisfy the agricultural production requirement.

Purpose of the present invention is exactly the requirement that will adapt to agricultural production, provides a kind of and 12 to 20 horsepowers of ferti-seeding machineries that the seeding quality that small tractor is supporting is good, province plants, emerges complete, rational in infrastructure.

For reaching the combined seed and fertilizer drill that goal of the invention designs, form by hanging frame and the fertilizer apparatus on it and dispenser and plough, the suspension type frame only the stage casing of main beam be provided with an anti-skidding land wheel, the fertilizer apparatus of combined seed and fertilizer drill is the fertilizing box of band outer groove wheel defertilizing wheel, seeding apparatus is the seeding box of the vertical seeding of band internal filling type garden dish, plough under fertilizing box and the seeding box is that spear is following, oblique perching knife formula plough in a narrow margin on the blade, only 2 to 3 centimetres of plough width, applicator boot is positioned at before the seed opener, 1 to 3 centimetre of lateral deviation, applicator boot spear setting height(from bottom) is low 1 to 2 centimetre than the seed opener spear, there is V-arrangement two-wheel press wheel the seed opener back, and the anti-skidding land wheel of combined seed and fertilizer drill links to each other with seed wheel with defertilizing wheel with driving-chain through intermediate chain wheel.

The plough that the utility model pastes the stubble combined seed and fertilizer drill all can bury on toothing hard place and saline land smoothly, resistance is little, only 2-3 centimetres of trench digging width, preserve soil moisture, earth backing is tight, and institute can not contact, can not burn kind to fertilize with the seed kind of burying, there is not kind of a brush in the seeder, service free, seeding is reliable, the single seed rate height; Complete machine is reasonable in design, intensity good, in light weight, stable drive is reliable.

As embodiment of the present utility model, three groups or four groups of the fertilizing and seeding apparatus on its frame, line-spacing is adjusted arbitrarily.Except that broadcasting corn, also can broadcast the lint cottonseed behind the replacing seeding unit.

Further describe the utility model below in conjunction with accompanying drawing.

Fig. 1 pastes stubble combined seed and fertilizer drill schematic diagram for the utility model.

Fig. 2 is the state diagram of overlooking of this machine.

Fig. 3 is the vertical garden of this a machine internal filling type dish seeding unit schematic diagram.

Fig. 4 is this mechanical shovel cutter formula plough schematic diagram in a narrow margin.

Fig. 5 is 4 vertical view.

As shown in Figure 1 and Figure 2, the main beam 10 of this machine is a solid drawn tube, on integral device 13 is arranged, an anti-skidding land wheel 5 is only installed by cantilever 7 in main beam 10 center.Chemical fertilizer case 16 times is by outer groove wheel defertilizing wheel 15, defertilizing tube 12 and by breaking perching knife 2 and side plate 1 and the fertile pipe 3 breaking ploughs of forming 4 that fall.Be that the vertical seeding unit 18 of internal filling type reaches by kind of a ditch perching knife 26, side plate 27 and kind of pipe 23 seed openers of forming 22 that fall below the seeding box 17.Breaking plough 4 and seed opener 22 front and back not point-blank, 1 to 3 centimetre of lateral deviation.Seed opener 22 back are by the V-arrangement two-wheel packer of being made up of press wheel 25 24.Regulate the embedded depth of torque arm 8 and pull bar 20 controlled seed openers 22.Anti-skidding land wheel 5 drives intermediate chain wheel shaft 21 through driving-chain 6, drives outer groove wheel defertilizing wheel 15 through driving-chain 14 again, and drives the vertical garden of internal filling type dish seeding unit 18 through driving-chain 19.

As shown in Figure 3, seeding box has the exocoel 34 of the vertical garden of bottom outlet 35 logical internal filling types dish seeding unit 18 for 17 times, the seed kind enters inner chamber 32 from the side window of inner chamber 34 on inwall 33 again, insert vertical garden and coil nest hole 29 on 29 outer rims, along with the rotation of vertical garden dish 29, the simple grain seed kind in the nest hole 29 is protected down the row of being sent to seed position 29 at the retaining of garden arc

seed retaining plate

30,28 enter kind of a pipe 23 through the hole, and vertical garden dish 29 is driven by sprocket wheel 31.

As Fig. 4, shown in Figure 5, perching knife formula plough 4 in a narrow margin both can be made the breaking plough, can make seed opener again, and it is made up of perching knife 2, side plate 1, fertile pipe (or kind of the pipe that falls) 3 that fall, and width is 2 to 3 centimetres between the side plate 1, in slide plate 36 is arranged.

Claims

1, a kind of combined seed and fertilizer drill, form by the fertilizer apparatus on suspension type frame and its and seeding apparatus and plough, there is an anti-skidding land wheel in the main beam stage casing that it is characterized in that said suspension type frame, said fertilizer apparatus is the fertilizing box of band outer groove wheel defertilizing wheel, said seeding apparatus is the seeding box of the vertical seeding of band internal filling type garden dish, plough under fertilizing box and the seeding box is that spear is following, oblique perching knife formula plough in a narrow margin on the blade, applicator boot is positioned at before the seed opener, 1 to 3 centimetre of lateral deviation, applicator boot spear setting height(from bottom) is low 1 to 2 centimetre than the seed opener spear, there is V-arrangement two-wheel press wheel the seed opener back, and anti-skidding land wheel links to each other wheel with row with driving-chain through intermediate chain wheel with seed wheel.
