A vertical deep rotary tillage combined operation device for fertilization and seeding

Abstract

The invention discloses a vertical deep rotary tillage, fertilization and seeding combined operation device, which relates to the field of agricultural machinery. A seed guide pipe and a fertilization pipe are arranged in the cutter shaft of the rotary tiller, wherein the upper end of the seed guide pipe communicates with the seeding pipe through a connecting nut The lower end of the seed introduction pipe spreads the seeds into the land through the seed discharge port; the fertilizer in the fertilization pipe is discharged through the fertilizer discharge slot. The speed sensor and single-chip microcomputer are used as the main control, and the infrared detection device is used to ensure the accurate switching action of the valve. Finally, the even and deep plowing of the land is realized, and the fertilizer layer is laid to provide a good germination environment for the seeds. At the same time, the seeds are evenly and accurately The next row, to ensure no missed broadcast. The complexity of the agricultural machinery and the volume of the agricultural machinery are greatly reduced.

Description

technical field [0001] The invention belongs to the field of agricultural engineering and relates to a combined operation device for vertical deep rotary tillage, fertilization and seeding. Background technique [0002] With the development of science and technology, the level of agricultural mechanization in my country has been greatly improved, but at the same time, the multiple cropping index of land and the amount of fertilizer used are also rising, so the land situation in recent years is worrying. A series of problems of soil compaction and unbalanced physical and chemical properties have emerged. The traditional horizontal rotary tiller has the advantages of high work efficiency, larger farming area and good adaptability, but recently with the emergence of soil problems, people began to look for other rotary tillage methods, and then appeared vertical rotary tiller and As opposed to rotary tillage, they still have their own limitations. The existing fertilization an...

AI Technical Summary

Problems solved by technology

The existing fertilization and seeding technology has basically taken shape, but the leakage rate and germination rate are still the most important issues that people care about and restrict the increase of grain production

At the same time, cumbersome agricultural machinery procedures and bulky agricultural machinery play a certain role in restricting the improvement of agricultural productivity and the degree of agricultural mechanization.

[0003] The existing rotary tillage fertilization and seeding devices have the following disadvantages: the depth of rotary tillage is not enough, the disturbance to the soil is too large, the soil compaction and water loss are serious, and the balance of the physical and chemical properties of the soil itself is affected at the same time, and the seeds do not have a good germination environment; The adjustability and uniformity of sowing depth, the rate of missing seeding and germination rate still need to be improved, and the uniformity of fertilizer and the controllability of the distance from seeds need to be developed urgently, which is crucial to the improvement of the level of agricultural mechanization in my country; and other cumbersome agricultural machinery procedures, so that the efficiency of agricultural mechanization operations needs to be improved urgently

The structure of agricultural machinery is complex and the economy is low
