Abstract

The utility model discloses a three-disc type colter boot for separate application of seeds and fertilizers, which is arranged on a seed sowing machine and is characterized by comprising a rack, an upright column, a large disc, a medium disc, a small disc, a fertilizer tube and a seed tube. The upright column is arranged on the rack; the large disc, the medium disc and the small disc are respectively arranged on the upright column obliquely through rotating shafts and bearings; the large disc and the small disc form a first included angle; the large disc and the medium disc form a second included angle; and the fertilizer tube and the seed tube are respectively arranged in the first included angle and the second included angle. During the operation, the utility model can open two parallel W-shaped ditches in the soil with one deeper than the other; the fertilizer is applied in the deeper ditch, while the seed is sown in the shallow ditch; the fertilizer is applied more deeply than the seed, thereby realizing the deep application of the fertilizer for sowing in line, and effectively preventing the fertilizer from burning the seed; and with the deep application of the fertilizer, the utility model reduces the loss of nutrients, and improves the utilization rate of the fertilizer.

Description

Three disc type seed manures divide sowing and applying furrow opener

Technical field

The utility model relates to a kind of agricultural machinery, and the three disc type seed manures that the seeding and fertilizing use is installed on particularly a kind of sower divide sowing and applying furrow opener.

Background technology

Most wheat seeders are in order to pass through to adopt the disc type plough well, this plough makes to be broadcast the medium and small wheat seeds of soil and mixes same broadcasting in a ditch with chemical fertilizer, seed manure mixes to be executed planting patterns the kind of chemical fertilizer and quantity is very restricted, close or the directly contact because of the seed chemical fertilizer, plant and take place to burn, cause the wheat disconnected ridge that is short of seedling, finally influence wheat yield; In agricultural production, widely popularize the Precision Seeding agrotechnique, implement the sowing of wheat defective ejaculation amount, the fertilizer deep placement specification requirement, make the wheat individuality that impartial living space and standing area be arranged, existing disk seeding and fertilizing mechanism has not satisfied the enforcement of agriculture accurate technology, can not be completed the specification requirement under the fertilizer deep placement kind.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of large, medium and small three disc type seed manures that are applied on the sower and divides sowing and applying furrow opener, compact conformation, and through performance is good, uses reliable.

To achieve these goals, the utility model provides a kind of three disc type seed manures to divide sowing and applying furrow opener, be installed on the sower, it is characterized in that, comprise: frame, column, big disk, middle disk, roundel, fertilizer guiding tube, grain conductor, described column is installed on the described frame, described big disk, middle disk, roundel tilts to be installed on the described column by rotating shaft and bearing respectively, described big disk and roundel have first angle, described big disk and middle disk have second angle, and described fertilizer guiding tube and grain conductor are separately positioned among described first angle and second angle.

Three above-mentioned disc type seed manures divide sowing and applying furrow opener, and wherein, described column is two of sizes, and described big disk, middle disk are separately positioned on the described big column, and described roundel is arranged on the described post.

Three above-mentioned disc type seed manures divide sowing and applying furrow opener, wherein, described first angle forms first joining, described second angle forms second joining, described first joining is lower than described second joining, described fertilizer guiding tube is arranged among described first angle, and described grain conductor is arranged among described second angle.

Three above-mentioned disc type seed manures divide sowing and applying furrow opener, and wherein, described second angle is greater than described first angle.

Three above-mentioned disc type seed manures divide sowing and applying furrow opener, and wherein, described bearing is installed on the described column by bearing block respectively.

Three above-mentioned disc type seed manures divide sowing and applying furrow opener, and wherein, described first joining is lower than described second joining 3cm～17cm.

Beneficial functional of the present utility model is: compared with prior art, have following good effect:

1, below the crop sowing deep placement chemical fertilizer and seeds below 3 centimetres, solves seed manure and mix kind of the problem of burning of executing;

2, can precisely topdress the wheat crop root and promote plant growth;

3, fertilizer deep placement reduces the loss of running off, and effectively improves chemical fertilizer utilization ratio;

4, novel structure is simple, compact, use is reliable, is grain-production energy savings new tool, and agricultural production is produced huge economic benefit, social benefit and ecological benefits.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

Embodiment

Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are done concrete description:

See also the front view of Fig. 1 the utility model structure chart; Fig. 2 is A-A among Fig. 1, B-B revolved sectional view.

In the embodiment shown in the figure, the three disc type seed manures that the utility model discloses divide sowing and applying furrow opener, comprising: big disk 1, middle disk 8, roundel 14, big column 3, post 15,

bearing block

4,10,13, grain conductor 7, fertilizer guiding tube 2.

As shown in the figure, large, medium and small three disc type seed manures divide sowing and applying furrow opener, mainly be three and face disk 1 directly, 8, bearing block 4 on 14,10,13, respectively by disk rotating shaft 5,11 and roundel axle 12 be installed in the size two columns 3, on 15, on big column 3, fertilizer guiding tube 2 and grain conductor 7 are installed, post is equipped with roundel, it is characterized in that, face disk 1 directly for three, 8,14 diameter difference, roundel 14 and big disk 1, angle between middle disk 8 and the big disk 1 does not wait, have the first angle β 1 between roundel 14 and the big disk 1, have 2, three disk rotating shafts 5 of the second angle β between middle disk 8 and the
