Abstract

The invention discloses an ejector for soil deep placement. The ejector comprises an airflow conveyer for conveying high-pressure jet airflow, wherein an airflow channel and a fertilizer channel for feeding a fertilizer are arranged in the airflow conveyer; the airflow channel is in a venturi structure; a fertilizer outlet of the fertilizer channel is communicated with a shrinkage area of the airflow channel; and the airflow conveyer is used for conveying the high-pressure jet airflow. The airflow channel is in the venturi structure, and can play an accelerating role in the flowing airflow; meanwhile, the fertilizer channel and the fertilizer outlet of the fertilizer channel are communicated with the shrinkage area of the airflow channel; and negative-pressure material suction is formed on a powder fertilizer by the high-pressure jet airflow flowing through the airflow channel, so that the powder fertilizer is mixed with the high-pressure je airflow in the airflow channel to enter soil along with the high-pressure je airflow, and thus the target of the deep placement is reached.

Description

technical field [0001] The invention relates to the field of deep loosening of soil, in particular to a sprayer for deep application of soil. Background technique [0002] Existing soil mechanized subsoiling technology is to use high-horsepower tractors to drive the plowshares to move laterally to loosen the soil, break the bottom of the plow, and deepen the plowing layer, while the deep application of silty fertilizers is to spread the fertilizer granules on On the ground surface, use a rotary tiller or tractor to rotate or plow into the soil. There is no mobile soil deep loosening and deep application related technology and its complete set of equipment. [0003] There are some technical deficiencies in the above subsoiling and deep fertilization methods. First, the technology is single and cannot be carried out in a complete set. Fertilization, soil loosening, and mobile silt fertilizer transportation are carried out separately, and integration has not been realized; seco...
