Abstract

A fertilizing and seeding single body on a tillage-free seeding machine which is applied to the corn stalk covered ground belongs to the technical field of agricultural machinery. The fertilizing and seeding single body comprises handles (3) of a colter, the colter, fertilizer dropping pipes and seed dropping pipes, wherein the colter is installed at the lower parts of the handles (3) of the colter. The utility model is characterized in that the seed dropping pipes are two seed dropping pipes which are divided into a left seed dropping pipe (5) and a right dropping pipe (6); the fertilizer dropping pipe (4), the left seed dropping pipe (5) and the right dropping pipe (6) are arranged in a shape like the Chinese character 'yi' from front to back; a pipe opening of the fertilizer dropping pipe (4), a pipe opening of the left seed dropping pipe (5) and a pipe opening of the right seed dropping pipe (6) are totally installed in the colter and arranged triangularly. When the single body is used, two rows of seeds and one row of chemical fertilizer can be seeded and applied at one time. Since the number of the handles of the colter is reduced by a half, the distance between every two neighboring handles of the colter is increased by one time. The ditching resistance of the whole machine is reduced, and the passing performance of the seeding machine is obviously increased. The utility model has the advantages of raw material saving and lower cost.

Description

Corn stalk mulched ground no-tillage fertilizing planter

Technical field

The present invention relates to a kind of ferti-seeding monomer that is applied on the corn stalk mulched ground no-tillage seeding machine, belong to agricultural machinery technological field.

Technical background

Conservation tillage has obtained to a certain degree popularization in China, and has created certain economic benefits and social benefit.But owing to be not particularly suitable for the no-tillage seeding machine of China's national situation; especially in the area of yielding two crops a year; the no-tillage seeding machine of the direct no-tillage seeding wheat of maize straw total crop return can not reach instructions for use always after autumn; make that the further popularization of conservation tillage is hindered, the no-tillage seeding machine of the suitable China's national situation of development is extremely urgent.

The technological difficulties of no-tillage seeding machine are through performances.The key of through performance is distance and the version between the plough, is the limitation of the arrow spade type plough of representative owing to operation principle with the patent No. 91227723.8, is easy to stop up when planting line-spacing less than 20 centimetres of no-tillage seedings; And be the disk coulter of representative with the patent No. 92105515.3, because the normal pressure that needs when cost height and no-tillage seeding makes the application on no-tillage seeding machine be restricted greatly.

Summary of the invention

The purpose of this utility model is that a kind of corn stalk mulched ground no-tillage seeding machine that both had been applicable to will be provided, and is applicable to the corn stalk mulched ground no-tillage fertilizing planter of traditional sower simultaneously again, the blockage problem that very easily takes place when sowing to solve.

Comprise in order to reach the technical scheme that the purpose of this utility model takes: plough handle 3, be installed in the plough of plough handle 3 bottoms, lower fertilizer tube 4, the pipe of sowing, it is characterized in that: the pipe of sowing has two, is divided into lower-left kind pipe 5 and bottom right kind pipe 6, and lower fertilizer tube 4, lower-

left kind pipe

5,6 one-tenth front and back of bottom right kind pipe in-line are arranged, and the mouth of pipe of the mouth of pipe of the mouth of pipe of lower fertilizer tube 4, lower-left kind pipe 5, bottom right kind pipe 6 all is installed in plough inside, and triangularity is arranged.

In the above-mentioned corn stalk mulched ground no-tillage fertilizing planter, the mouth of pipe of the mouth of pipe of lower-left kind pipe 5, bottom right kind pipe 6 is positioned at the top, back both sides of the mouth of pipe of lower fertilizer tube 4 side by side at a distance of 8～12 centimetres.

In the above-mentioned corn stalk mulched ground no-tillage fertilizing planter, plough comprises sword 1, following sword 2, shovel face 8, is dovetail wedge angle spade.

The utility model corn stalk mulched ground no-tillage fertilizing planter has the following advantages: use this monomer 1., once broadcast 2 row seeds, 1 row chemical fertilizer, two kinds of row are at a distance of 8～12 centimetres, and chemical fertilizer is in two row seed middles, carry out wide-narrow row planting, the seed manure spacing meets agriculture requirement.The quantity of plough handle reduces half on the sower, and the distance between the plough handle doubles, and complete machine trench digging resistance reduces, and the sower through performance obviously improves.2. this monomer can be installed on the sower beam easily, both has been applicable to that no-tillage seeding machine also was applicable to traditional sower.3. save raw material, reduced cost, improved economic benefit; This corn stalk mulched ground no-tillage fertilizing planter will promote the further popularization of conservation tillage.

Description of drawings

Fig. 1 is the front view of the utility model corn stalk mulched ground no-tillage fertilizing planter;

Fig. 2 is the vertical view of the utility model corn stalk mulched ground no-tillage fertilizing planter;

Fig. 3 is the left view of the utility model corn stalk mulched ground no-tillage fertilizing planter.

Specific embodiments

Shown in the figure: 1 is sword on the plough, and 2 is sword under the plough, and 3 is the plough handle, and 4 is lower fertilizer tube, and 5 is that lower-left kind pipe, 6 is bottom right kind pipe, and 7 is seed, and 8 are plough shovel face, and 9 is chemical fertilizer.

Below in conjunction with accompanying drawing concrete structure of the present utility model is described:

As Fig. 1, Fig. 2, shown in Figure 3, lower fertilizer tube 4 is fixedlyed connected with plough handle 3, as welding, arranges and is connected with lower-

left kind pipe

5,6 one-tenth front and back of bottom right kind pipe in-line.The mouth of pipe of lower fertilizer tube 4 is below the mouth of pipe front side of the mouth of pipe of lower-left kind pipe 5, bottom right kind pipe 6, and three's triangularity is arranged, and the three is installed in the inside of plough.Plough by last sword 1, down sword 2, shovel face 8 are welded on and form on the plough handle 3, are dovetail wedge angle spade, the plough penetration performance of this spade is good, it is strong to return native ability automatically.The plough handle is arranged on the beam of sower with known method, the different spacing of the wide row of wheat can be by regulating between the plough handle apart from realizing.Regulate sowing and fertilization depth by regulating the upper-lower position of plough handle on beam.

During operation, use this corn stalk mulched ground no-tillage fertilizing planter, once broadcast 2 row seeds, 1 row chemical fertilizer, carry out wide-narrow row planting, 4～6 centimetres of seed levels, 8～10 centimetres of fertilization depths, 8～12 centimetres of width between two kinds of row guarantee that the seed manure spacing meets agriculture requirement.Plough buries and leaves ditch shape, because the plough shape is dovetail wedge angle spade, so do not dig substantially, fertile in the centre, two row are planted above the side of fertilizer, and after fertilizer was executed, fallen to planting, this maintenance of soil matrix original position fell back in kind of a ditch, the fertile ditch naturally, cover kind, on the fertilizer, finish trench digging, fertilising, sowing, the whole process of earthing.

It should be noted that at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
