Air-flow type deep-plowing and deep-fertilizing system

Abstract

The invention discloses an air-flow type deep-plowing and deep-fertilizing system. The system comprises a plowing and fertilizing gun inserted into soil and an air-flow type particle fertilizer supply device for conveying the particle fertilizer to a fertilizer inlet of the plowing and fertilizing gun, wherein the air-flow type particle fertilizer supply device comprises an air compressor and a primary material conveying pipe which is connected with an air outlet of the air compressor; the primary material conveying pipe is provided with a material feeder which absorbs materials through a Venturi structure. The system can solve the problems of deep-plowing and deep-fertilizing soil and movably conveying the particle fertilizer for a long distance, and can be suitable for scaled cultivation of a plain and also suitable for scattered parcels such as mountainous areas and hills. The particle fertilizer conveying system is convenient to move, the soil is not compressed, and the conveying amount is large. The deep-plowing and deep-fertilizing system is not high in power requirement, small in volume, light in weight, flexible to move and little in soil compression, can relatively effectively mix the fertilizer particles with soil, and has little damage on growing root systems of plants.

Description

technical field [0001] The invention belongs to the field of modern agricultural power equipment, and in particular relates to an airflow type subsoiling and deep application system. Background technique [0002] In agricultural operations, due to the solid nature of fertilizers, the applicability of liquid transportation is not high. In the prior art, the transportation of powder fertilizers is mainly carried by transport vehicles, such as tractors, tricycles or carts. This transportation method requires high infrastructure and better road traffic. At the same time, it cannot be used for mobile operations, which may cause damage to the cultivated land or cause serious compaction. Moreover, if it is on a hillside or hilly area, it is inconvenient for motor vehicles or rickshaws to walk, and it can only be transported by manpower. Not only is the transportation volume small and the efficiency is low, but it is also impossible to accurately transport the powder fertilizer to t...

Problems solved by technology

[0002] In agricultural operations, due to the solid nature of fertilizers, the applicability of liquid transportation is not high. In the prior art, the transportation of powder fertilizers is mainly carried by transport vehicles, such as tractors, tricycles or carts. This transportation method has high infrastructure requirements and requires better road traffic. At the same time, it cannot be used for mobile operations, which may cause damage to the cultivated land or cause serious compaction.

Moreover, if it is on a hillside or hilly area, it is inconvenient for motor vehicles or rickshaws to walk, and it can only be transported by manpower. Not only is the transportation volume small and the efficiency is low, but it is also impossible to accurately transport the powder fertilizer to the place where it needs to be fertilized; Granular solid fertilizer is troublesome, it cannot realize mechanized automatic loading and unloading, and the work efficiency is low. On the other hand, the existing deep application of powder fertilizer generally spreads the fertilizer powder on the surface by tractors (most of them use manual labor), and then uses rotary tillage Rotary plowing or plowing into the soil by machines or tractors, there is no mobile soil deep loosening and deep application related technology and complete sets of equipment
