Description

Technical Field

[0001] The utility model belongs to agricultural machinery, and mainly relates to a machine for fertilizing a 1.1-meter large ridge seed bed for double-row planting of crops. Background Art

[0002] The agronomic technology of planting corn or soybean crops in double rows on 1.1-meter ridges is a new planting technology that has been vigorously promoted and applied on a large scale in northern my country, especially in Heilongjiang Province in recent years. Since this agronomic technology has good drought and waterlogging resistance, it provides better seedbed conditions for the growth and development of crops, which not only increases the yield per unit area of ​​crops, but also improves the quality of crops. At present, fertilization operations need to be carried out simultaneously during the construction and processing of the 1.1-meter ridge seedbed. However, due to the shortcomings and defects in the structural design of fertilizer machines, the existing fertilizer machines can only concentrate all fertilizers in the middle part of the ridge platform to complete single-line fertilization with a single fertilization depth and no stratification. It is difficult for crops to absorb fertilizer nutrients during growth, and the fertilizer utilization rate is low, resulting in fertilizer loss and waste. Summary of the Invention

[0003] The purpose of this utility model is to address the problems existing in the above-mentioned prior art, and in combination with the current needs of the construction and use of 1.1 large ridge double-row seed beds, to develop and design a 1.1-meter large ridge fertilizer applicator, which can achieve the purpose of greatly improving the fertilizer utilization rate, reducing fertilizer loss and waste, and ensuring the reasonable absorption of fertilizer by crop growth and development through scientific and reasonable fertilizer application.

[0004] The basic design of the utility model is: a 1.1-meter large ridge fertilizer spreader, including a frame, a three-point suspension frame and a fertilizer box assembly are respectively installed on the front end and the upper end of the frame, deep fertilizer double disc furrow openers are respectively installed on the lower side of the front end of the frame, located between the large ridge double row seedling belts, and horizontally corresponding to each other; shallow fertilizer double disc furrow openers are respectively installed on the lower side of the rear end of the frame, located on the large ridge platform outside the large ridge double row seedling belts, and horizontally corresponding to each other; a plurality of fertilizer pipes connect the fertilizer box assembly to the deep fertilizer double row seedling belt. The disc furrow opener is connected to the shallow fertilization double disc furrow opener. The deep fertilization double disc furrow opener is used for furrowing and fertilizing on large ridges and platforms of double rows of soybeans with a depth H1 of 12-14 cm, and the shallow fertilization double disc furrow opener is used for furrowing and fertilizing on large ridges and platforms of double rows of soybeans with a depth H2 of 8-10 cm; the deep fertilization double disc furrow opener is used for furrowing and fertilizing on large ridges and platforms of double rows of corn with a depth H1 of 16-18 cm, and the shallow fertilization double disc furrow opener is used for furrowing and fertilizing on large ridges and platforms of double rows of corn with a depth H2 of 10-12 cm.

[0005] The utility model takes the double-row crop seedling belt as the benchmark on a 1.1-meter large ridge platform, and realizes a four-layered fertilization method of two deep and two shallow fertilizers, which can provide fertilizer nutrition supply for the growth of double-row crops for a longer time, and the fertilizer is fully and reasonably utilized, reducing the loss and waste of fertilizer. It has the characteristics of reasonable structure, high fertilizer utilization rate, being beneficial to crop absorption, and promoting the improvement of crop yield and quality per unit area.
