Abstract

The utility model relates to a double-plant corn seeder, which belongs to an agricultural machine. The corn seeder has the following characteristics: a land wheel is arranged between two forks of an H-shaped frame, a seed-discharging roller and a fertilizer-discharging roller which are respectively provided with nine or twelve pits are respectively arranged on the left and right of the center of the land wheel, bearings are arranged on the outer ends of the two rollers, and a shaft passes through the two rollers; both sides of an outer circle of the land wheel are respectively provided with nine or twelve holing tubes, an inner circle is connected with the upper ends of the holing tubes, lower duckbill sections of the holing tubes are extended out of the outer ring, and are arranged in parallel at the left and the right, chins of each pair of duckbill sections are perpendicularly integrated with a soil-pressing plate, and are connected with the duckbill sections through a small shaft, and a tension spring is which can open the soil-pressing plate is arranged at the middle of the small shaft; the two rollers are respectively provided with a seed box and a fertilizer box, soft separating sheets are arranged in front of the box bottoms, discharging tubes are arranged under the soft separating sheets, wherein a seed-removing sheet is arranged in the left discharging tube, the lower end of the left discharging tube is provided with a seed-observing corner, and the upper parts of the two boxes are fixed on the frame by connecting plate. The utility model has the advantages of reliable seeding, accurate plant spacing, quickness and labor saving.

Description

Two strain corn seeding devices

Technical field: the utility model belongs to agricultural machinery technological field, relates in particular to a kind of pair of strain corn seeding device.

Background technology: in the manual sowing apparatus that uses, mainly contain two kinds of dazzling device and rollers at present, though dazzling device sowing effect is good, because the limitation of force method, not only spacing in the rows is difficult to grasp, and labour intensity is big, and speed is slow too; Various rollers, seeding down can not be directly perceived.

Summary of the invention: the purpose of this utility model, be to overcome the shortcoming that has various technology now, a kind of new product is provided, make sowing work convenient power-saving more, accurately and reliably, and improve ventilation and penetrating light, improve lodging tolerance.

Two strain corn seeding devices partly are made up of the wheel, roller segment and relative motionless axle, case, the frame that rotate.Be characterized in: establish a land wheel between H type framework two fork mouths, set up separately about the land wheel center respectively with the seeding roller and the distributing roller of 9 or 12 nest eyes, bearing is established in two roller outer ends, connects with axle; Two sides, land wheel outer ring respectively distributes 9 or 12 and pricks the soil pipe, prick soil pipe upper end and connect inner ring, following duckbilled section is stretched out the outer ring, about side by side, every pair of interior chin of duckbilled becomes factory's font to fuse with the firming plate of front, with little axle and duckbilled polyphone, the tensile spring that can get out the firming plate is established in little axle stage casing around the corner; Set up kind of case and fertile case on two rollers separately, establish soft separate sheet before at the bottom of the case, divide into delivery pipe, establish seed sheet clearly in the wherein left delivery pipe, the lower end is established and is seen the seed angle, and two upper box parts are with connecting plate and frame fixation.

This utility model sowing is reliable, and spacing in the rows is accurate, convenient power-saving.

Description of drawings: the utility model is elaborated below in conjunction with Figure of description: Fig. 1 is a left view, and Fig. 2 is a rearview.In Fig. 1 and Fig. 2: 1, land wheel, 2, the seeding roller, 3, distributing roller, 4, connecting plate, 5, handrail, 6, framework, 7, plant case, 8, fertile case, 9, delivery pipe, 10, inner ring, 11, see the seed angle, 12, duckbilled, 13, tensile spring, 14, the firming plate, 15, the outer ring, 16, chin, 17, soft separate sheet, 18, the nest eye, 19, clear seed sheet, 20, feed outlet, 21, prick the soil pipe, 22, the fork mouth, 23, nut, 24, axle.

Embodiment: press roller before the use earlier, again according to spacing in the rows, plant grain size and fertile measuring, adjust land wheel 1, seeding roller 2 and distributing roller 3, then, load onto seed manure, push away before holding handrail 5, with the delivery pipe 9 of the kind case 7 of framework 6 one and fertile case 8 along inner ring 10 move ahead (the land wheel outside is stretched out at the seed angle 11 of seeing of wherein planting case), seeding roller and distributing roller and prick native duckbilled 12 with turning to down before the land wheel, be subjected to tensile spring 13 effect and the bundle soil duckbilled that buries of remaining silent when forwarding nearly mid point down to, because open firming plate 14 is close to outer ring 15 by the extruding of ridge platform, drives chin 16 and dehisce; Simultaneously, soft separate sheet 17 is let slip seed manure in the nest eye 18, clear seed sheet 19 forces seed to fall immediately, seed is slipped to along left delivery pipe and sees that the seed angle blocked by the land wheel sidewall, provide certain seeing the seed time, when seeing that the seed angle advances to when relative with feed outlet 20, seed is dropped into (the opposite side chemical fertilizer is directly dropped into and pricked the soil pipe) in the bundle soil pipe 21 that has opened duckbilled immediately, finishes seeding and fertilizing.

The well stimulation of two strain corn seeding devices is: the distance that will should broadcast two strains is originally spared into 3 strains, therefore, indent amount must be 3 multiple, and as 9 (3 groups) or 12 (4 groups), every group comprises two strain transplanting stocks and the 1 strain marquis position of filling the gaps with seedlings, as (30+30 changes 20+20+20 into) centimetre, save seed again for the Shi Youmiao that is short of seedling in transplanting stock can move, marquis's nest eye of filling the gaps with seedlings is only offered 1, all the other sealings, as (2+1+2+0+2+0) strain=9 hole rollers, (2+1+2+0+2+0+2+0) strain=12 hole rollers.Add and broadcast 1/6th or 1/8th the marquis seed of filling the gaps with seedlings, reseed and to rob preceding solar term, prevent tender corn, both increased output, improve quality again than looking into seedling.In addition, this pair of strain formula drawn back the distance between per two groups of two strains, is beneficial to ventilation and penetrating light, improves lodging tolerance.

Compare with dazzling device, remain silent equally and bury, dehisce to be unearthed, the sowing effect is identical, but this wheelbar-row type, total weight is born by the earth, only need thrust to get final product, and spacing in the rows is accurate.All will exert oneself when pricking and put on the dazzling device, spacing in the rows is easy " walking kind " also, and not only both shoulders are ached, and efficient is also low relatively.

Expensive seed price forces people to have to broadcast simple grain, and the shortcoming of existing roller is exactly that seeding down can not be directly perceived.Compare with roller, this machine changes the top that is set to axle with the kind case of close proximity to ground, utilizes drop between itself and ground to establish and sees the seed angle, sees that one is broadcast one, kind relieved.
