Abstract

The utility model belongs to the technical field of agricultural machines, in particular relating to a dibbling and seeds sowing machine, comprising an outer casing and a core print. The utility model is characterized in that a hole-typed ring is disposed on the periphery of the core print, the outer casing is in fixed arrangement with the side end of the core print, a cavity-shaped seeds separating groove with integral periphery is formed between the outer casing and the hole-typed ring, input openings are disposed inside the seeds separating groove mounted on the left section of the horizontal central line of the seeds sowing machine, and output openings are arranged on the core print positioned on the vertical central line of the seeds sowing machine. The output openings which are vertical in radial direction and inclined in axial direction are in liner connection, and are communicated with the external portion of the outer casing. When the hole-typed ring rotates, the seeds enter hole-typed through-holes in a seed-filling area. In the course of the ascending of the hole-typed through-holes, the seeds of which the gravity does not enter the hole-typed through-holes drop down and return to the original position by the self-gravity of the seeds, enabling the seeds which enter the hole-typed through-holes to be operated to the position corresponding to the output openings to be discharged. Compared with the existing technology, the utility model has the advantages that an original dibbling and seeds sowing machine can be improved to be an accurate dibbling machine without the need of arranging a seed-cleaning device, adding an air apparatus or an electric device, and simultaneously the utility model can solve the problems of the breaking and crushing of the seeds and frictional resistance.

Description

The precise spot-sowing seeding unit

Technical field

The utility model belongs to agricultural machinery technological field, is specifically related to a kind of program request seeding unit.

Background technology

At present, known program request seeding unit is an indent type.Input hole is located in seeding unit overcoat vertical center line epimere ± 30 degree scopes, and delivery outlet is located at the lower end of corresponding overcoat.A rotating core print is arranged in the overcoat, be equipped with the nest eye on the core print, when seed falls into nest intraocular on the core print from input hole, because the rotation of core print, the seed of nest intraocular is promptly along with the nest eye slips in the overcoat, finish moving and from delivery outlet, discharging successively of half circumference, finish seed and from coenosarc, isolate individual operation, ditch then and bury.But seed enters nest at the moment, does not just in time hold one or several seeds in each nest eye, but half seed is often arranged at the nest intraocular, and half outside.Like this, form the shearing-crushing of seed and the frictional resistance of seeding unit between the nest eye rear wall that is moving and the antetheca of input hole with regard to clamping seed.

In order to address this problem, common way is that seed scraping device is installed at overcoat input hole antetheca place, forces to scrape kind, as flexible materials such as hairbrush, rubber.But this material is rubbed with the hands at frequent seed and is forced down, and very easily damage, and the accuracy of scraping kind is not high.External then directly be conceived to extraction to individual seed, promptly utilize the positive negative pressure or the suction of air or blow, utilize electromagnetic principle or suction or put.To increase the outer another set of auxiliary equipment of necessary device but do like this.The result is a complex structure, and cost enlarges, and uses inconvenient maintenance, especially is difficult to be used in mountain region, animal power, coarse cereals district.

Summary of the invention

The utility model has overcome the deficiencies in the prior art, need not to scrape kind of a device, need not gas, electric attachment device, solved the technical problem of program request seeding unit from structure to seed shearing-crushing and frictional resistance.

The utility model is to realize like this, the precise spot-sowing seeding unit comprises overcoat, core print, it is characterized in that on the outer circumference surface of core print the type orifice ring being housed, overcoat and core print side install, be wholecircle week cavity shape branch kind of a groove between overcoat and the type orifice ring, input hole is located in the branch kind groove of seeding unit horizontal center line left side section, and delivery outlet is located on the core print of seeding unit vertical centre line position, linearly connect, radially vertical, axial deflection, and with the overcoat exterior.When the type orifice ring rotates, seed flows into from input hole and divides kind of the district of filling that forms in kind of the groove in the angle of repose, enter again in the through hole of type hole, in running, make center of gravity not enter the seed of type hole through hole when type hole through hole rises, lean on the seed deadweight to fall and separate back original position, the seed that makes center of gravity enter type hole through hole moves to the feed outlet corresponding position and discharges.Have the natural angle of repose characteristic owing to plant stream, seed can remain occupied state in kind of the district of filling of minute kind groove, and the admittance of assurance type hole through hole.Change corresponding type orifice ring according to the geometry of different seeds, promptly satisfy the sowing requirement of various crop.

Overcoat of the present utility model and type orifice ring are that quarter turn cavity shape divides that kind of groove is local to be contained, and with kind of a case disjunctor, two core prints are contained in the support plate both sides of type orifice ring respectively, are movingly with the type orifice ring, two core prints are provided with the delivery outlet of symmetry.

Be provided with three circle type hole through holes on the periphery of type orifice ring of the present utility model side by side, core print is provided with asynchronous three delivery outlets arranged side by side.

The utility model compared with prior art has the following advantages: 1, simple in structure, and need not be provided with and scrape kind of a device, more need not increase gas, electric installation, can solve the seed shearing-crushing and the frictional resistance of seeding unit; 2, can satisfy the mechanization Precision Seeding technological transformation of mountain region, animal power, coarse cereals conventional tillage.

Embodiment

With reference to the accompanying drawings embodiment is further described, embodiment 1 is as Fig. 1, shown in Figure 4, be the basic model of precise spot-sowing seeding unit, overcoat 1 is whole containing the in wholecircle week, between overcoat 1 and type orifice ring 3, be provided with for seed operation and the branch kind groove 7 that separates, input hole 2 is located in the branch kind groove 7 of seeding unit horizontal center line left side section, delivery outlet 6 is located on the core print 5 of seeding unit vertical centre line position, linearly connects, and is radially vertical, axial deflection, and with overcoat 1 exterior.When type orifice ring 3 clockwise directions rotated, seed flowed into from input hole 2 and divides kind of the district of filling that forms in kind of the groove 7 in the angle of repose, in the hole of the inflow type again through hole 4.Make center of gravity not enter the seed 8 of type hole through hole, when type hole through hole 4 rises, lean on the seed deadweight to fall and separate back original position, the seed 8 that makes center of gravity enter type hole through hole 4 moves to the delivery outlet corresponding section and discharges.Present embodiment designs in the minimum position of charging seed of sower, is applicable to the required precision height, and focuses on the sower that solves the thinning problem, as millet.
