Hydrodynamic spiral fertilizer injection pump

Abstract

The invention discloses a hydrodynamic spiral fertilizer injection pump. The pump comprises a hydrodynamic operation zone, a single-way fertilizer injection passage and a liquid fertilizer conveying zone; the hydrodynamic operation zone comprises a machine shell, a water inlet and a water outlet are formed in the surface of the machine shell, and the machine shell is internally provided with a hydrodynamic transmission mechanism; the single-way fertilizer injection passage comprises a shell which is fixedly connected with the machine shell and internally provided with a rotating shaft, the rotating shaft is connected with the hydrodynamic transmission mechanism, internally provided with a passage and sleeved with a tapered piston, and a bearing is connected to the bottom in a detachable mode; the bearing is formed by nesting multiple bearing joints, and helical blades are connected to the bearing in a clamped mode; a shell body is arranged on the periphery of the helical blades, and the shell body is formed by connecting multiple shell joints through threads; one end of the shell body is in threaded connection with the shell, and the other end of the shell body is connected with afertilizer barrel through a pipe fitting and a connecting sleeve; the helical blades, the bearing and the shell body form the liquid fertilizer conveying zone. By means of the fertilizer injection pump, the technical problems that the fertilizer absorbing effect is likely to be affected by the structure size, the manufacturing accuracy and the material formulation can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural implements, and in particular relates to a hydrodynamic screw fertilizer injection pump. Background technique [0002] The integration of micro-irrigation, water and fertilizer is a high-tech that organically combines agricultural irrigation and fertilization. With the help of pressure irrigation system, the fertilization liquid mixed with soluble solid fertilizer or liquid fertilizer is integrated with irrigation water through fertilization equipment. , Accurately, regularly and quantitatively supply crops for absorption. [0003] With the widespread application of pipeline irrigation technologies such as micro-irrigation, sprinkler irrigation, and low-pressure pipeline water delivery, fertilization equipment and technologies have also been rapidly developed and applied. At present, fertilization devices without external power include differential pressure fertilization tanks, Venturi injec...
