Abstract
The utility model discloses a pressing wheel of a no-tillage planter, which is characterized in that: the top surface of the pressing wheel is in an elliptical arc curved structure, and the two ends of an elliptical arc are respectively tangential to an extension line which forms an angle of 27-29 degrees with the side of the pressing wheel; and a major axis and a minor axis of the elliptical arc are respectively 90-120mm and 38-42mm in length. In the manufacture, the curve of the top surface of the pressing wheel is calculated according to the elliptical arc curved structure of the pressing wheel, and then the outline dimension of the pressing wheel is determined in practice. Since the pressing wheel with the elliptical arc curved structure is adopted, the top surface of the pressing wheel can be matched with the surface of a planting furrow, and the planted seeds are in moderately tight combination with covering soil after pressing, thereby improving the rate of emergence and reducing the rate of seeding. Compared with the traditional no-tillage planter, the rate of seeding can decrease by about 10%.
Description
Technical field
The utility model relates to agricultural machinery, relates in particular to no-tillage seeding machinery.
Background technology
No-tillage seeding belongs to the protective farming technique that state key is promoted; this technology is a major transformation of the autumn in several thousand being turned over the conventional tillage technology of spring ploughing; it covers the face of land with no-tillage seeding and stalk stubble is main contents; have the soil wind erosion of alleviating, water erosion; reduce production costs; plurality of advantages such as increase production, increase income; being one improves the ecological environment; realize the scientific agriculture method of agricultural sustainable development, it is to accelerating the modernization of agriculture, promoting growth of agricultural efficiency, increasing peasant income all to have realistic meaning.Development along with no-tillage technology, the no-tillage seeding machinery of multiple version is also come out one after another, at present the no-tillage seeding machinery that China is ripe have that Hebei, Shaanxi, Shanxi etc. economize three, four kind of type, these types have been represented the integral level of China's no-tillage seeding machinery substantially.Generally speaking, these wheat no-tillage planters move to maturity through for many years practice and improvement, and several types of common this substantially can the ordinary production operation in this area.
But these types are in applying for many years, and its promotion rate can't be satisfactory, and except the conventional tillage force of habit, its main cause is that these types also exist some defectives and deficiency on structural design.Because this wheat no-tillage planter press wheel all adopts the steel plate welding fabrication, complex manufacturing technology not only, unreasonable structure, service life is short simultaneously, the more important thing is because the restriction of technology, cause the wheel face and the seed furrow surface of the press wheel of this unreasonable structure not to match, with agriculture requirement a certain distance is arranged, thereby influence the emergence rate of wheat.Be to guarantee emergence rate, thereby have to strengthen seeding quantity,, increase about 15%, wasted the grain kind, increased production cost, reduced the benefit that the peasant plants grain than traditional planting with sowing machine amount through measuring and calculating of actual specific.
The utility model content
The utility model provides a kind of no-tillage seeding machine press wheel with particular curvature, to overcome the prior art drawback.
Be to realize the utility model purpose, this no-tillage seeding machine press wheel is characterized in that the end face of described press wheel is the elliptic arc curved-surface structure, and the two ends of described elliptic arc are respectively with to be 27 °～29 ° extended line tangent with the press wheel side.
The major axis of described elliptic arc and the length of minor axis are respectively 90～120mm and 38～42mm.
In actual fabrication, at first go out the theoretical curve on seed furrow surface according to the data computation of measuring in the field, calculate the curve of press wheel end face then according to the theoretical curve on the requirement of agronomy and seed furrow surface, determine the appearance and size of press wheel again on the basis of practice, the press wheel structure that next requirement according to processing technology will have the steel plate welding now changes cast iron hub-type press wheel structure into.
The technological progress that the utility model is obtained: owing to adopt press wheel with elliptic arc curved-surface structure, the wheel face and the seed furrow surface of press wheel are matched, make broadcast into seed form combining of tight appropriateness with top earthing, thereby improved emergence rate, reduced seeding quantity, compare with existing no-tillage seeding machine, can reduce seeding quantity about 10%.Simultaneously owing to adopt casting, with existing steel plate welding press wheel relatively, reduced processing cost, prolonged product service life, in production test, received good effect, be subjected to peasant user's welcome deeply.

Embodiment
As Fig. 3, Fig. 4, shown in Figure 5, the end face of this no-tillage seeding machine press wheel 5 is the elliptic arc curved-surface structure, and the two ends of described elliptic arc 7 are respectively with to be the extended line 6 at α angle tangent with press wheel 5 sides.This α angle is 27 °～29 °, and the α angle is set at 28 ° in the present embodiment.The major axis of described elliptic arc 7 and the length of minor axis are respectively 90～120mm and 38～42mm, and the length of major axis and minor axis is respectively 110mm and 40mm in the present embodiment; The length h of described extended line 6 is set at 8～12mm, and the length h of this extended line 6 is set at 10mm in the present embodiment.
As shown in Figure 1 and Figure 2, the wheat no-tillage planter operation, be directly to carry out (not needing to plough) in the field that has gathered in the crops corn, the rotary blade that the gearbox 4 that tractor drives drives on the cutter shaft rotates, soil loosens in the ridge that rotary blade will need to sow, kind of the pipe that falls of back is directly broadcast seed in these loosen the soil, and the press wheel by the utility model elliptic arc curved-surface structure 5 rolls reality to soil at last, thereby reaches the effect that not only chesson not only reduces seeding quantity but also improves emergence rate.
The utility model press wheel 5 is unit of wheat seeder, and the sower of different fabric widths is formed in available a plurality of unit, and the utility model Figure 1 shows that the fabric width that 6 unit are formed is the actual use type of 2 meters wheat no-tillage planter.Be positioned at top seed manure case 3 seed and fertilizer are housed, with kind of the pipe that falls seed is broadcast in the soil by broadcasting the seed box; The output shaft of tractor is given rotary tillage assembly 1 by gearbox 4 with transmission of power, drives the rotary blade rotation, and rotary blade is the loosing soil on sowing ridge; The effect of press wheel 5 is that the soil of broadcasting seed is rolled reality; Support assembly 2 organically is connected as one each part of sower.
