Description

Multi-purpose seed planter

The utility model relates to a kind of agricultural machinery, particularly a kind of multi-purpose seed planter that carries out bunch planting, drilling and overlay film.

Wheat plastic-film-covered cultivation new technology is one of country's great promotion project of the enforcement period of the ninth five-year plan, but because the mulch bunch planting that uses at present machinery is as ZBDFX-10A type Mulching and hill-drop sowing machine performance imperfection, make the volume increase advantage of this new technology fully not show, peasant planting enthusiasm baffles, and it is very big to promote resistance.

The main working parts of existing hill-drop planter is exactly 5 seed tubes, and kink is equipped with 13 groups of duckbilleds and 13 groups of rag iron springs on each seed tube circumference on frame.Dress seed in seed tube during work, driven rolling forward by pull bar, bury when interior when duckbilled Jianzha County, spring bearer plate contacts to earth, and the compression spring is opened movable duckbilled, seed in the seed tube just flows out, along with the seed tube rotates forward, the pressing plate built on stilts, spring restores, movable duckbilled is closed again, finishes bunch planting action.Duckbilled whenever opens and once flows out seed and how much depend on the feed outlet size in the seed tube and the pace of tractor, and other accessory has: two furrowers and two disk coverers are installed before and after the frame both sides.During work, mulch film hangs over seed tube front, after mulch film is paved, the seed tube rolls across, duckbilled with seed broadcast as previously mentioned bury in, disk coverer earthing on the ground film edge gets final product, the major defect of this machine is: (1) amount of sowing can not be regulated and control, seeding quality is poor: this machine belongs to the influence that the self-flowing type seeding is subjected to external condition, the seeding quantitative variation is very big, does not guarantee the uniformity of seed discharge capacity, the uniformity of each row discharge capacity and the stability of total displacement, the mu amount of sowing can not be adjusted simultaneously, can not adapt to agriculture requirement.(2) the some acupoints is unreliable, the seed number per uniformity is poor, the leakage sowing rate height: this machine is to utilize face of land compression spring, that equidistant bunch planting is carried out in the folding of control duckbilled since in the actual production field piece flatness and soil hardness inconsistent, the seed tube all changed at any time apart from the height on ground when this machine advanced, thereby the stressed size that spring bearer plate lands also can not be consistent, causes the open angle of duckbilled big more, time is long more, and the quantity of sowing is big more; Otherwise the quantity of then sowing is few more, even causes a large amount of floats and broadcast leakage, and float and leakage sowing rate are even more serious in the twice wheel ditch that tractor with small four wheels two back wheel loads are crossed.(3) mu sowing cave number is few: this machine is subjected to the influence of morphing in the restriction of structure space and the real work, and mu sowing cave number is less.(4) sowing depth is shallow excessively, seed earthing poor performance: a. is because the restriction of structure, in order to guarantee certain cave number, the duckbilled quantity of arranging on seed tube circumference is many and seed tube diameter is little, adding spring bearer plate also is arranged in and has occupied very big position on the same circumference, cause seed tube fulcrum many, pivot distance is near.There are several fulcrums to support during seed socket joint ground simultaneously, cause the duckbilled soil-entering resistance to increase; Produce when b. the seed tube rotates and float: it is the trifilar suspension formula that this machine connects with tractor with small four wheels, and hill-drop planter weight is transferred on one's body the tractor with small four wheels, and the weight ability of having only the seed tube is to the duckbilled formation pressure that buries.In seed tube when work, rotate around the axle center and move forward, and duckbilled pressure and soil support force balance each other, and penetrates in the soil by duckbilled tip acute angle entirely, and the seed tube is subjected to the upwards unsteady pace of effect of the entad component that pulling force produces big more when advancing; This buoyancy is big more, and duckbilled is not easy to bury more.C. because structural limitations, duckbilled can not open seed when the deep-seated that buries is put, be subjected to the influence of pace and field piece flatness in addition, and duckbilled embedded depth difference alters a great deal, and occurs a large amount of floats often; In addition, when this structure such as soil were done, seed still can cover some soil, and was bigger as soil moisture, mobile poor, and bacterium is germinateed, goes out in influence thereby seed just might not cover soil.(5) because the restriction of structure, operating speed can not be accelerated, and has limited the raising of productivity ratio, and hill-drop planter can be broadcast mu number and be about 1/4th of existing 12 row drilling machine every day.(6) overlay film, bunch planting can only be used for, drilling can not be used for, function singleness.
