Problems solved by technology

At present, the Venturi fertilizer applicator popularized and applied at home and abroad is to connect a Venturi tube in parallel to the irrigation pipeline and set a flow-limiting regulating valve on the pipeline. This kind of fertilizer applicator needs a higher rated working pressure, and generally requires If the pressure is above 0.15-0.25MPa (25m water head pressure), it cannot work normally under low pressure

Abstract

A low-pressure uniform-irrigation fertilizer applicator comprises a rack, an embedded negative-pressure uniform fertilizer applicator, a flowmeter with a flow regulating valve, a fertilizer bucket, afertilizer injecting pipe A and a fertilizer injecting pipe B; the embedded negative-pressure uniform fertilizer applicator body is fixed to the bottom of the rack and comprises a fertilizer applicator tube-shell and a fertilizer applicator core, a fertilizer suction port runs through the fertilizer applicator tube-shell, and is connected with one end of the fertilizer injecting pipe B, the fertilizer applicator core comprises a Venturi tube, a stepped trapezoidal jet port and a cyclone generator, one end of the stepped trapezoidal jet port serves as an inlet end of the Venturi tube, and one end of the cyclone generator serves as an output end of the Venturi tub; a liquid outlet of the fertilizer bucket is connected with one end of the fertilizer injecting pipe A, and the flowmeter with aflow regulating valve is mounted between the other end of the fertilizer injecting pipe A and the other end of the fertilizer injecting pipe B. The fertilizer applicator can realize visually and accurately uniform water and fertilizer integrated irrigation, and mixing uniformity of fertilizer in the pipe network is improved.

Description

technical field [0001] The invention belongs to the field of agricultural irrigation and fertilization, in particular to a low-pressure speed uniform irrigation and fertilization machine. Background technique [0002] Fertilizers are important tools and equipment for modern agricultural production. At present, the Venturi fertilizer applicator popularized and applied at home and abroad is to connect a Venturi tube in parallel to the irrigation pipeline and set a flow-limiting regulating valve on the pipeline. This kind of fertilizer applicator needs a higher rated working pressure, and generally requires If the pressure is above 0.15-0.25MPa (25m water head pressure), it cannot work normally under low pressure. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a low-pressure uniform irrigation and fertilizer applicator. Uniformity of fertilizer mixing in the net. [0004]...
