Abstract

The utility model provides a multi-function seeder which can dig holes by rolling. The bridge frame comprises a seed box cover, a seed box, a seed duct and a fertilizer box cover, a fertilizer box, a fertilizer duct which distribute symmetrically and in a line. The bottom of the frame is provided with a rotating sowing wheel. Two storehouses comprising a seed cover and a fertilizer cover are installed on the both sides of the sowing wheel symmetrically. The middle of the storehouse is provided with a sowing valve and a fertilizing valve. A plurality of seed hoppers and fertilizer hoppers symmetrically radial distributing along the axis are arranged on the both faces of the sowing wheel, distributors are arranged on the edge of the sowing wheel. The shift lever is corresponding to the sowing wheel and forms an intermittent kinematic pair with cam shifting forks. When the distributors on the edge of the sowing wheel are opened one by one, the function of sowing and fertilizing is finished after the output of the seed and the fertilizer. By using the double-storehouse of seed and fertilizer simultaneously combined seeding mechanism, the quantity of seed and fertilizer, the depth of plant and the equidistance of planting are can be controlled. The seed and the fertilizer are put into the planting pit simultaneously, which realizes the simultaneously sowing of seed and fertilizer, guarantees the quality of sowing and improves efficiency of planting.

Description

Roll and prick the cellular type multifunctional seed drill

Technical field

The utility model relates to a kind of no-tillage machine band sower, especially discloses a kind of rolling and has pricked the cellular type multifunctional seed drill, belongs to agricultural machinery technological field.

Background technology

In agricultural production process, often need to apply base fertilizer in the time of planting seed, and market sale small farm seeding machinery can only be sowed the grain kind, seed and base fertilizer can't be sowed simultaneously, function is comparatively single; Particularly when the operation of artificial bundle hole, the sowing distance should not be grasped, and labour intensity is big, and speed of drilling is slow, influences output; Use animal power, machine strip sowing planting with sowing machine, earth backing is thick, destroys former ridge, the loss of moisture of breaking ground, and it is slow to emerge, and can't satisfy the needs that modern agriculture is produced.

Summary of the invention

The utility model provides a kind of rolling to prick the cellular type multifunctional seed drill, have equidistant sowing, seed nutriment in a fertilizer from, do not destroy characteristics such as former ridge type, overcome the shortcoming of existing sower function singleness.

The technical solution adopted in the utility model is as follows: by the seed case lid that is symmetrically distributed side by side, the seed case, seed conduit and fertile case lid, fertile case, fertile conduit constitutes the frame of bridge-type sower, the bottom of frame is a driving shaft, which is provided with rotating seeding wheel, the bilateral symmetry spiral-lock of seeding wheel is put the seed lid and is put fertile lid and constitutes two storage bins, respectively with the seed conduit, fertile conduit is communicated with, be provided with sowing in the middle of each storage bin, the fertilising valve, the both sides wheel face of seeding wheel is radial some seed buckets and the fertile bucket of being symmetrically distributed with along the axle center, be communicated with storage bin respectively, the blowing duckbilled of seed bucket and fertile bucket is located on the wheel rim of seeding wheel, the corresponding driving lever of each blowing duckbilled, driving lever one end and blowing duckbilled constitute interlinked mechanism, the other end constitutes the intermittent movement pair with the cam shift fork that is fixed on the main shaft, blowing duckbilled on the unlatching seeding wheel wheel rim of order, row's seed fertilizer is finished the seeding and fertilizing function.

Seed, fertilizer are poured into respectively in seed box and the fertilizer box, when promoting sower, seeding wheel rotates, and seed, fertilizer are respectively by the rotation of seeding wheel, in the storage bin that evenly bleeds, enter into seed bucket and fertile bucket by sowing, fertilising valve, seeding wheel rotates by shift fork and drives the driving lever action, and driving lever will be planted, fertile blowing duckbilled opens, and makes fixed race seed and fixing fertile amount in seed bucket and the fertile bucket, broadcast simultaneously and to bury, finish one-stop operation.

Good effect of the present utility model is: employing is planted, fertile two storage synchronization combinings are sowed mechanism, be seeded into simultaneously by seeder in the plantation hole of soil, kind, fertile quantity, planting depth, equidistant seed adjustment are controlled, realized that seed fertilizer one sows synchronously, guaranteed the quality of sowing, improve plantation efficient, saved production cost, used a machinery to finish several work.

Embodiment

According to shown in Figure 1, by the seed case lid 1 that is symmetrically distributed side by side, seed case 2, seed conduit 3 and fertile case lid 1 ', fertile case 2 ', fertile conduit 3 ' constitutes the frame of bridge-type sower, the bottom of frame is a driving shaft 8, which is provided with rotating seeding wheel 13, the bilateral symmetry spiral-lock of seeding wheel 13 is put seed lid 4 and is put fertile lid 5 and constitutes two storage bins, respectively with seed conduit 3, fertile conduit 3 ' is communicated with, be provided with sowing in the middle of each storage bin, fertilising valve 14, the both sides wheel face of seeding wheel 13 is radial 12

seed buckets

6 and 12 fertile buckets 7 of being symmetrically distributed with along the axle center, be communicated with (referring to Fig. 2 and Fig. 3) respectively with storage bin, the blowing duckbilled 12 of seed bucket 6 and fertile bucket 7 is located on the wheel rim of seeding wheel 13, as shown in Figure 4, each blowing duckbilled 12 corresponding driving lever 20, driving lever 20 1 ends are provided with driving lever bearing 9 and constitute interlinked mechanism with blowing duckbilled 12, the other end constitutes the intermittent movement pair with the cam shift fork 21 that is fixed on the main shaft 8, blowing duckbilled 12 on unlatching seeding wheel 13 wheel rims of order, row's seed fertilizer is finished the seeding and fertilizing function.Advancing fertile mouthful 15 is to link to each other with fertile lid 5 by fertilizer guiding tube 3 end openings, enters storage bin (Fig. 2) by advancing fertile mouthful 15.Transfer fertile pointer 16 on the fertile lid of projection 5, leaven box plate 11 links to each other under the pointer, have on the pointer and high-volume control washer 23, control the quantity that enters mouth by the pointer control, transfer seed pointer 17 on fertile box plate 11 outer rings on plane, the base plate of going here and there links to each other with seed base plate 10, has control washer 23 on the pointer, seed through pointer control grain number, enters blowing duckbilled 12 by the seed storage warehouse.It is two ends that two braces 18 all are connected driving lever 20 tops, is connected on two blowing duckbilleds 12, and driving lever support 19 constitutes concave groove with main wheel 13, driving lever 20 is put into groove, with forming lever on the pin uranium string.Both sides are divided in driving lever 20 stage casings, hang up driving lever spring 25, spring 25 other ends hang on the main wheel spring(-supported) mount 22, play to push aside and once can regain a work done, driving lever top shift lever axis 9, when main wheel 13 rotates, shift fork 21 is stirred driving lever bearing 9, finishes a work done, and main wheel shelves post 24 is an one with main wheel 13, be that the displacement of restriction driving lever plays the role of positioning, restriction driving lever zone of action.
