A kind of farming fertilization open delivery drill
Technical field
The utility model belongs to agricultural machinery technological field, relates to a kind of farming fertilization open delivery drill.
Background technology
In agricultural production, initial crushed stalk, rotary tillage and sowing etc. all are that single Work machine is finished, the screw sowing machine of integration of operation function had appearred having afterwards, but this screw sowing machine can only carry out operation at pure land or root stub land, can not pulverize at upright maize straw and cover directly sowing of back.Gradually people developed can directly pulverize the high stubble of a upright maize straw or wheat stalk, the one step completed sowers of flow chart such as band farming, fertilizer deep placement, sowing, suppression, for example the stalk cutting and tillaging and planting machine of ZL 99126557.2.But also there are some shortcomings in this stalk cutting and tillaging and planting machine, as shown in Figure 1, 2, the top of its seeding leg is two pipes and unifies the version that the lower end of burying is sowed in lines, the seeding leg seed of this version can only be two lines from the lower end of burying in lines and discharge when discharging, sowing sees soil cross sectional representation Fig. 3 after the operation for details in the subset on two lines.The advantage of this mode is farm works such as traditional tools such as hoe easy to use are intertilled, weeding, but its shortcoming is at a distance of nearer between seed and the seed, the land area that single seed (the single individuality of crop) occupies is less relatively, thereby influences overall yield.In recent years along with the widespread usage of weed killer herbicide etc., mass peasants carry out the field weeding operation with traditional tools such as hoes seldom again in the process of crop growth, and the population yield of field crops is made up of the output of each single individuality, improve population yield, will try every possible means to improve the output of each single individuality.The most direct method that improves single individual output is exactly to improve the floor space of single individuality, so, how to coordinate colony and individual relation, improve population yield and just become a research direction by improving individual output.
The utility model content
The purpose of this utility model provides a kind of farming fertilization open delivery drill that seed is evenly spread out.
The utility model is by the following technical solutions:
A kind of farming fertilization open delivery drill comprises transmission system, cultivating member, fertilizer leg, seeding leg and packer, and described seeding leg comprises body and dustpan-shaped outlet, and the lower end of body is located in dustpan-shaped outlet.
Bottom surface in the described dustpan-shaped outlet is provided with seed body.
Described seed body is cone shape or semicircle cone.
The width of described dustpan-shaped outlet is 13-15cm.
Described body is a pipe.
The utility model is keeping on existing sower (ZL99126557.2) farming, fertilising and the earthing function basis of invariable, original top is the two pipe unifications structure that the lower end sows the seeding leg of version in lines of burying changes a body into, the seed export of seeding leg lower end changes into dustpan-shaped, and is provided with seed body in dustpan-shaped outlet inside.Seed falls the back from body and beats on seed body, thereby seed is evenly spread out, and finally evenly disperses to discharge from dustpan-shaped outlet.Sower after the utility model improves can make seed evenly scatter in the field, can increase the floor space of the single individuality of seed in the field under the prerequisite that does not change seeding quantity, reduces blank ground area, can make crop yield improve about 5%.

Embodiment
Cover open delivery drill, shown in Fig. 4,5,6, comprise transmission system 11, body part 12, cultivating member 13, fertilizer leg 14, seeding leg 10, packer 15 and chemical fertilizer and seeds casing 16, seeding leg 10 comprises tubular body 1 and dustpan-shaped outlet 2, the lower end of body 1 is located in dustpan-shaped outlet 2, bottom surface in the dustpan-shaped outlet 2 is provided with semicircle cone seed body 3, and the width of dustpan-shaped outlet 2 is 13-15cm.
By soil cross sectional representation after Fig. 7 embodiment 2 covering open delivery drill operations as can be seen, the seed of being sowed after the sower operation of the present utility model 41 is evenly distributed substantially, seed 4 after the prior art operation among soil cross sectional representation Fig. 3 then is the form that is two lines, contrast as can be seen, seed 41 uniformities are bigger after the utility model operation, increased the distribution area of seed, reduced blank ground area, to the not influence of distribution of fertilizer 5 in the field.
