Description

Wheat precision seeder

Technical Field

The utility model relates to an agricultural machine especially relates to a simple and easy seeder.

Background

At present, the production level of agricultural mechanization is greatly improved, and some agricultural machines which are convenient for production and cultivation are widely popularized, so that the method plays a positive role in reducing the labor shortage in rural areas and the labor intensity. For example, the miniature rotary tillage machine, the miniature simple seeding and fertilizing machine can complete the tillage operation which can be completed by at least two persons, and the machine is convenient to use, greatly improves the labor efficiency and liberates the labor force.

A precision seeder can be used for fertilizing, seeding or fertilizing and seeding simultaneously, and greatly facilitates agricultural production operation. However, in the practical course of production, such problems arise, which plague some agricultural producers: the wheat is accurately sown by weight of each mu, is the same land parcel as what, has the same soil fertility, the same soil moisture content and the same sowing period, uses the same chemical fertilizer variety and quantity, and even uses the same wheat variety purchased in the same place; some seeds are 22-23 jin per mu, some seeds are 45-46 jin per mu, the difference of the seeding amounts is so much, the yield per mu of the wheat in the second year is almost equal, and the wheat is not wasted in so many seeds.

① precision sowing groups are small, the dynamic structure of the groups is reasonable, the bad tillering is little, the earning rate is high, ② root system is developed, the absorbing capacity is good, the vitality is strong, ③ is good in ecological benefit, high in efficiency and low in consumption, ④ structure is more reasonable, the light energy can be fully utilized, the photosynthetic conditions are improved, the photosynthetic products are produced to be multiple, ⑤ is high in tillering and large in panicle, the precision sowing is good naturally under the condition permission of the conditions, specific analysis is needed for how much the sowing amount is calculated, specific situations are needed, and the method is not clear at a glance, and the method is related to factors such as the land capability, the fertility, the soil moisture, the ground temperature, the self-attribute of the seeds (germination rate, emergence rate and tillering capability) and the like.

Taking the plots with slightly different fertility of the soil for farmers as an example, through soil sampling analysis, the sowing amount of the wheat needs to ensure that the wheat has a high yield of more than 500 kilograms per mu, namely 40-50 thousands of ears per mu is guaranteed, namely 10 thousands of basic mu (if 4 ears per wheat can be tilled) is enough, if the thousand seeds of the wheat are 40 grams, the sowing amount of 22-23 jin per mu is enough by considering the germination rate, emergence rate and survival rate of the seeds, the existing comprehensive factors such as soil fertility accumulation and temperature and the like, and the high-yield requirement can be met. And the wheat is not very dense and the yield is not very different under the condition of sowing 45-46 jin.

It is problematic whether the seeder is concerned. We carefully examined an external fluted-wheel type precision seeder for one-time seeding, first a seeder capable of simultaneous seeding of seed and fertilizer, in order to simplify the structure, the seed-discharging leg is fixed behind (one line) the seed-discharging leg, which is 4-5 cm below the seed-discharging leg in the vertical plane, that is: the seeder can sow the fertilizer 4-5 cm below the seed layer and the fertilizer below the seed layer can be absorbed when the root of the seed sprouts grows to 4-5 cm. Theoretically there should be no problem, and in order to find out the true phase of the matter, we come together to the sown plot and pull open the sealed seeds by hand, and as a result, found that: a considerable part of seeds and fertilizers are mixed together to form mixed sowing (the seeds and the fertilizers are not distributed on different three-dimensional layers as imaginable), so that seedlings are burned, and a part of seeds are disabled. The original seed sowing legs are closely attached to the back of the fertilizer sowing legs, after the fertilizer is sowed, the fertilizer sowing legs turn to soil blocks on two sides, and if some seeds cannot be refilled, the seed sowing legs on the back can already sow the seeds, so that part of the seeds leak to the fertilizer layer, and the mixed sowing of the seeds and the fertilizer causes seedling burning. Therefore, the seeds are wasted, and after the problem is found, the idea is necessarily required to be improved to solve the problem.

Disclosure of Invention

The utility model discloses not enough to prior art, on current seeder basis, provided a modified wheat precision planter, change the seed metering leg of seeder into to with the angle of one side crooked 4-5 centimetres (for the leg of fertilizeing), make the three-dimensional interval of kind, fertile, become kind, fertile three-dimensional, horizontal interval, neither change wheat planting ("five, nine" wide narrow row or wait row spacing) agronomy requirement planting pattern, thoroughly avoided kind, fertile mixed seeding fever seedling phenomenon again.

The utility model discloses the technical scheme who adopts:

a wheat precision seeder comprises a seeder body, and a fertilizer discharging leg and a seed discharging pipe leg which are connected with the seeder body, wherein the seed discharging pipe legs are arranged at the back of each fertilizer discharging leg side by side, the plane of the seed outlet pipe of each seed discharging pipe leg and the plane of the fertilizer discharging pipe of the fertilizer discharging leg have an included angle of 30-60 degrees, and the seed outlet pipe of each seed discharging pipe leg bends towards the same side and extends for a distance of 3-5 cm.

The wheat precision planter, each group arranges fertile leg, seed metering piping leg and connects through the connecting seat ear separately, one of them connecting hole is the bar hole (the seed export of adjustable seed metering piping leg and the upper and lower distance that the fertile pipe of row fertilize leg goes out), both pass through bolt-up connection.

The utility model has the advantages that:

1. the utility model discloses wheat precision planter changes the seed metering leg of seeder into to with the angle of 4-5 centimetres of one side bending (for the leg of fertilizeing), makes the three-dimensional interval of kind, fertile, becomes kind, fertile three-dimensional, horizontal interval, neither changes wheat planting ("five, nine" wide and narrow row or wait row spacing) agronomy requirement planting mode, has thoroughly avoided kind, fertile mixed sowing burning seedling phenomenon again. Practice proves that: because the burning of seeds is avoided, the whole function of the seeds is exerted, the seeding can be naturally carried out for a short time, and the effects of saving cost and increasing efficiency and saving cost and income are achieved.

2. The utility model discloses wheat precision planter, reasonable in design, simple structure can not increase structural cost, has nevertheless produced the effect of "saving the cost and increasing the efficiency, saves the cost and increases the income", can practice thrift the seed cost, promotes easily, and application scope is wide, can be used for the seeding and the synchronous use of fertilization of peanut, beans, wheat etc..
