Description

One ditch double row wheat no-till sowing unit

technical field

The invention relates to a one-ditch double-row wheat no-tillage sowing unit applied to a seeder, belonging to the technical field of agricultural machinery.

technical background

Conservation tillage has been promoted to a certain extent in our country and has created certain economic and social benefits. However, since there is no no-tillage seeder that is particularly suitable for my country's national conditions, especially in areas with two crops a year, the no-tillage seeder that returns all corn stalks to the field after autumn and directly sows wheat with no-tillage has not been able to meet the requirements for use. Further promotion is hindered, and it is imminent to develop a no-tillage planter suitable for my country's national conditions.

The technical difficulty of the no-tillage planter is through performance. The key to the passing performance is the distance between the openers and the structural form. Due to the limitation of the working principle of the arrow shovel opener represented by the patent No. Blockage; and the disc opener represented by the patent No. 92105515.3 is limited in application on no-tillage seeders due to the high positive pressure required when the cost is high and no-tillage sowing.

Contents of the invention

The object of the present invention is to provide a wheat no-till sowing unit with one ditch and two rows, which is suitable for both no-tillage seeders and traditional sowers, and the sower using the unit has better passing performance.

The technical solutions adopted to achieve this goal include:

Opener handle 6, the main opener installed in the lower part of the opener handle 6, the fertilizer opener 7, the planting pipe and the fertilizer pipe connected with the opener handle 6, it is characterized in that, in the main opener There are two kinds of openers installed inside the ditch, divided into right ditch 8 and left ditch 10, right ditch 8, left ditch 10 and fat ditch 7 are arranged in a triangle , and all three are set inside the main opener.

In the above-mentioned one-ditch double-row wheat no-tillage sowing unit, the lower seeding pipe is divided into the lower left seeding pipe 1 and the lower right seeding pipe 3, and the fertilizer lowering pipe 2, the lower left seeding pipe 1 and the lower right seeding pipe 3 closely follow the opener Arrange in a word behind handle 6.

In the above-mentioned one-ditch double-row wheat no-tillage sowing unit, the right kind of ditch opener 8 and the left kind of ditch opener 10 are above the rear two sides of the fertilizer ditch opener 7 .

In the above-mentioned no-tillage sowing unit of wheat with two rows in one ditch, the lower left seeding tube 1 and the lower right seeding tube 3 have a distance of 8 to 12 centimeters between the openings of the two.

This one-ditch double-row wheat no-till sowing unit has the following advantages:

1. When sowing the same number of rows of wheat, the number of opener handles on the planter using this single unit is reduced by half, the distance between the opener handles is doubled, and the passability of the seeder is significantly improved.

2. This one-ditch double-row wheat no-till sowing unit sows 2 rows of seeds and 1 row of chemical fertilizer at a time. The distance between the two tube openings of the lower left seed tube and the lower right seed tube is 8 to 12 cm. The fertilizer is placed in the middle of the two rows of seeds, and the width Row planting, the number of planting rows remains unchanged, and the spacing between seed and fertilizer is guaranteed to meet the agronomic requirements.

3. The sowing unit can be conveniently installed on the sower beam, which is suitable for both no-tillage and traditional sowers.

4. Saving raw materials and reducing costs; this one-ditch double-row wheat no-till sowing unit will promote the further promotion of conservation tillage.

specific implementation plan

The concrete structure of the present invention is described below in conjunction with accompanying drawing:

Among Fig. 1 and Fig. 2: 1 is the lower left seed pipe (in Fig. 1, its lower part is cut off), 2 is the lower fertilizer pipe, 3 is the lower right seed pipe, 4 is the seed, 5 is the chemical fertilizer, and 6 is the ditch opener Handle, 7 is fertilizer ditch opener, and 8 is right kind of ditch opener, and 9 is main ditch opener (in Fig. 1, its left wing is cut off), and 10 is left kind of ditch opener. In this embodiment, the front ends of the fertilizer opener 7 and the main opener 9 are welded together.

As shown in Figure 1 and Figure 2, the fertilizer opener 7, the right opener 8, and the left opener 10 are connected to the main opener, and the three are arranged in a triangle, and the fertilizer opener 7 is opened on the right. Ditcher 8 and left kind of ditcher 10 front side below, and all three are installed in main ditcher 9 inside. The lower fertilizer pipe, the lower left seed pipe 1 and the lower right seed pipe 3 are respectively attached to the back of the fertilizer opener, the left seed opener 10, and the right seed opener 8, and the lower fertilizer pipe, the left lower seed pipe 1 and the right lower The seed pipe 3 is arranged in a line following the opener handle 6, which is conducive to reducing the passage resistance.

In actual production, the upper part of the lower left seed pipe 1 and the lower right seed pipe 3 can be integrated, and then separated left and right at the bottom, and connected with corresponding openers. Different spacing of the wide rows of wheat can be achieved by adjusting the distance between the opener shanks by arranging the opener shanks on the beam of the planter in a known manner. Adjust seeding and fertilization depth by adjusting the opener handle up and down on the beam.

During the operation, the fertilizer ditch is opened by the fertilizer opener, and the seed ditch is opened by the seed ditch. The fertilizer ditch is below the side of the seed ditch. A part of the soil will also be turned into the fertilizer ditch when the ditch is opened. The seeds fall into the seed ditch, and the soil turned by the seed opener will naturally fall back into the seed ditch. The main opener also ditches at the same time to protect the seed ditch and fertilizer ditch. The original position falls back, and after the seed and fertilizer openers ditch and return to the soil, they cover the seed ditch and fertilizer ditch, completing the whole process of ditching, fertilizing, sowing, and covering soil. The depth of sowing is 4-6 cm, the depth of fertilization is 8-10 cm, the width between the two rows is 8-12 cm, and the fertilizer is placed in the middle of the two rows of seeds. Agronomic requirements.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be Modifications or equivalent replacements without departing from the spirit and scope of the technical solutions of the present invention shall be covered by the claims of the present invention.
