Description

a combined seeder

technical field

The utility model relates to the technical field of seeders.

Background technique

Most of the corn planters currently used are equipment that can simultaneously perform seeding operations and formula fertilizer fertilization operations. After the corn planter's sowing and fertilization operations are completed, the application of organic fertilizers and the spraying of herbicides need to be carried out after the corn planter is finished. It is necessary to use different machines and tools to enter the ground two to three times to complete the entire operation, which is inefficient.

Excessive application of chemical fertilizers and pesticides is common in my country, which causes problems such as environmental pollution and the quality and safety of pesticide products. The main reason is that the amount of fertilization cannot be effectively controlled by agricultural machinery during the fertilization operation.

In areas with two crops a year, the wheat harvest has high stubble and large amount of stalks. Since the corn planter currently used does not have a stubble removal device, it leads to the phenomenon of planter congestion, seed drying, and seed racking, which affects crop yield; The sowing and discharge system has poor adaptability. After sowing, the closed weeding is carried out by spraying medicine. The wheat stubble is high and the spraying amount is large. The effect is not ideal, and the operation cost is increased. The traditional method of tillage and soil preparation consumes too much nutrients and activity of the soil itself, which will damage the organisms and microorganisms in the soil, resulting in the continuous lack of nutrients in the soil, resulting in the gradual loss of soil activity.

In view of the shortcomings of the current equipment, this scheme designs a combined operation machine for stubble cutting, planting, fertilization and spraying, which implements strip cutting, organic fertilizer and formula fertilizer are applied at the same time, and the method of spraying and sealing is carried out at the same time as sowing, which solves the above problems very well. .
