Background technique

Wheat is an important economic crop in my country, and the increase of wheat production and income is closely related to the national economy. Wheat single-grain precision sowing technology has attracted much attention recently. Compared with the existing sowing mode, it can reduce mutual shading, facilitate ventilation, and improve photosynthesis, and the roots of wheat grains are evenly spread out on the plane, which improves the water and fertilizer utilization rate and reduces the seed gap. Competition for nutrients between plants, and the root system develops robustly. It is beneficial to promote strong individual development, early tillering, more development of sheath tillers, increase the number of ears of wheat, and obtain a strong single plant with full ears, large ears and many grains, so as to increase the yield and income of wheat. Wheat single-seed sowing in the current price segment is mainly used for plot breeding, and there are not yet mature equipment for single-seed sowing operations, and it mainly relies on manual on-demand sowing, which has many problems such as low efficiency, high labor intensity, and poor operation quality. Single-seed wheat sowing can reduce the amount of seeds used and increase the yield per mu, which is the development direction of wheat planting in the future. Therefore, it is of great significance to study wheat single-seed precision seeders.

In the prior art, there are few single-seed planting machines, which are mainly aimed at plot operations and have poor practicability.

Therefore, it is an urgent problem to be solved at present to develop a seedling-belt type wheat rotary tillage and fertilization single-grain precision seeder suitable for plots and field operations.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, and provide a seedling-belt type wheat rotary tillage and fertilization single-grain precision seeder. The planter of the utility model can complete seedling belt rotary tillage, fertilization and wheat single-grain precision sowing operations at one time, so as to reduce the seeding amount per mu, reduce labor intensity, and improve operation efficiency and yield per mu.

The utility model adopts the following technical solutions:

A seedling-belt type wheat rotary tillage and fertilization single-grain precision seeder, including a frame, on which a three-point suspension mechanism, a transmission mechanism, a fertilizer discharge mechanism, a single-grain sowing mechanism and a pressing wheel are sequentially arranged from left to right; The transmission mechanism includes a gearbox on which a transmission shaft for transmitting tractor power to the gearbox is installed. The output shaft of the gearbox is connected to the rotary blade shaft, and the rotary blade is installed on the rotary blade shaft; the single-grain The sowing mechanism includes a seed box, on which a sowing opener, a sowing wheel and a soil-covering plate are respectively arranged, and a plurality of seed holes are alternately distributed on the sowing wheel.

Preferably, the fertilizer discharge mechanism includes a fertilizer tank, a fertilizer discharge device is installed in the fertilizer tank, and the fertilizer discharge device communicates with the fertilization opener installed under the frame through a hose.

Preferably, a guard plate is provided on the left side of the fertilizing ditch to prevent soil clods thrown by the rotary tiller from damaging the fertilizing ditch.

Preferably, the rotary cultivating knives are arranged at equal intervals.

The utility model has the beneficial effects of integrating the functions of rotary tillage and fertilization with single-grain precision sowing, has a simple structure and is convenient to install, can realize single-grain precision sowing operations in large fields, and increase the yield per mu.
