Description

No-tillage fertilization and sowing monomer in corn stalk mulched land

technical field

The invention relates to a fertilizing and sowing unit applied to a no-tillage seeder for corn stalk-covered land, which belongs 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. 91227723.8, it is easy to be blocked when the planting row spacing is less than 20 cm and no-tillage planting ; And the disc opener represented by the patent No. 92105515.3 is restricted in application on the no-tillage seeder due to the high positive pressure required when the cost is high and no-tillage sowing.

Contents of the invention

The purpose of this utility model is to provide a no-tillage seeder suitable for corn stalk-covered land, and at the same time suitable for no-tillage fertilization and sowing monomers for corn stalk-covered land of traditional seeders, so as to solve the problem of blockage problem.

The technical scheme adopted in order to achieve the purpose of the utility model comprises: ditch opener handle 3, the ditch opener that is installed in the ditch opener handle 3 bottoms, lower fertilizer pipe 4, lower seeding pipe, it is characterized in that: lower seeding pipe has Two, divided into the lower left seed tube 5 and the lower right seed tube 6, the lower fertilizer tube 4, the lower left seed tube 5, and the lower right seed tube 6 are arranged in a straight line. The mouth of pipe, the mouth of mouth of planting pipe 6 on the right side are all installed in the ditch opener inside, arranged in a triangle.

In the above-mentioned no-tillage fertilization and sowing unit covered with corn stalks, the mouth of the lower left seed pipe 5 and the mouth of the lower right seed pipe 6 are 8 to 12 cm apart, and are located side by side on the rear sides of the mouth of the lower fertilizer pipe 4 above.

In the above-mentioned no-tillage fertilization and sowing unit for corn stalk-covered land, the ditch opener includes an upper blade 1, a lower blade 2, and a shovel surface 8, which are in the shape of a dovetail-pointed shovel.

The utility model corn stalk-covered no-tillage fertilization sowing unit has the following advantages: 1. Using this unit, 2 rows of seeds and 1 row of chemical fertilizer can be sowed at a time, the distance between the two rows is 8-12 cm, and the chemical fertilizer is in the middle of the two rows of seeds , planting in wide and narrow rows, and the spacing between seed and fertilizer meets the agronomic requirements. The number of opener handles on the seeder is reduced by half, the distance between the opener handles is doubled, the ditching resistance of the whole machine is reduced, and the passability of the seeder is significantly improved. 2. This unit can be easily installed on the beam of the planter, which is suitable for both no-tillage planter and traditional planter. 3. The raw material is saved, the cost is reduced, and the economic benefit is improved; the no-tillage fertilization and sowing unit in the corn stalk-covered land will promote the further promotion of conservation tillage.

specific implementation plan

As shown in the figure: 1 is the upper edge of the opener, 2 is the lower edge of the opener, 3 is the handle of the opener, 4 is the lower fertilizer tube, 5 is the lower left seed tube, 6 is the lower right seed tube, and 7 is the seed , 8 is the shovel surface of the ditch opener, and 9 is the chemical fertilizer.

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

As shown in Fig. 1, Fig. 2 and Fig. 3, the lower fertilizer pipe 4 is fixedly connected with the ditch opener handle 3, such as welding, and is arranged in a line before and after the left lower seed pipe 5 and the right lower seed pipe 6 to connect. The mouth of mouth of lower fertilizer pipe 4 is below the mouth of mouth of lower left seed pipe 5 and the mouth of mouth of lower right seed pipe 6. The three are arranged in a triangle, and the three are all installed in the inside of the ditch opener. The ditch opener is formed by welding the upper blade 1, the lower blade 2, and the shovel surface 8 to the ditch opener handle 3. It is in the shape of a dovetail pointed shovel. This shovel-shaped ditch opener has good soil entry performance and strong automatic soil returning ability. 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 operation, use this corn stalk-covered land for no-tillage fertilization and sowing monomers, sow 2 rows of seeds and 1 row of chemical fertilizer at a time, plant in wide and narrow rows, sow at a depth of 4-6 cm, and fertilize at a depth of 8-10 cm. The width of the plant is 8 to 12 cm to ensure that the spacing of the fertilizers meets the agronomic requirements. The opener enters the soil to open a ditch shape. Because the shape of the opener is in the shape of a dovetail pointed shovel, the soil is basically not turned over. The fertilizer is in the middle, and the two rows are planted on the side of the fertilizer. After the fertilizer is applied and the seeds are dropped, the soil is basically maintained. The original position naturally falls back into the seed ditch and fertilizer ditch, covering the seed and fertilizer, and completes the whole process of ditching, fertilizing, sowing, and soil covering.

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