Water power extrusion fertilizer applicator

Abstract

The invention discloses a water power extrusion fertilizer applicator, comprising a water wheel drive assembly, an extrusion fertilizing assembly and a connecting transmission shaft. The water wheel drive assembly consists of an impeller and a housing, and the impeller is arranged at the front end of the transmission shaft. The extrusion fertilizing assembly consists of a housing, an elastic hose, a rotor and an extrusion wheel, and the extrusion wheel is arranged on the rotor which is arranged at the back end of the transmission shaft. The pressure water flow in a pipeline drives a water wheel to rotate, which drives the rotor to rotate through the transmission shaft, the extrusion wheel on the rotor alternately extrudes and releases the elastic hose, so that alternating pressure and vacuum occur in the hose to realize the extrusion and suction of the fertilizer liquid, thus accomplishing the process of fertilizer injection and fertilizer suction. The invention needs no added outside power, is convenient in installation and usage, and can be used in parallel on an irritation pipeline; the structure is simple, the manufacturing and using cost is low, the resistance to corrosion of the fertilizer liquid is strong, and the fertilizer liquid is unlikely to leak. The invention is suitable for the irritation fertilizing requirements of micro-irrigation, sprinkler irrigation, low pressure pipelines and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, and relates to farmland irrigation equipment, in particular to a hydraulic extrusion fertilizer matched with pipeline irrigation. Background technique [0002] With the widespread application of pipeline irrigation technologies such as micro-irrigation, sprinkler irrigation, and low-pressure pipeline water delivery, the corresponding irrigation and fertilization equipment and technologies have also been rapidly developed and applied. At present, irrigation and fertilization equipment without external power mainly include differential pressure fertilization tanks, Venturi fertilizer suction devices, piston and diaphragm fertilizer injection pumps, etc. Pressure differential fertilization tanks are simple to manufacture, low in cost, and do not require additional power equipment, but the concentration of fertilizer solution varies greatly, the number of times of adding fertilizer is...

AI Technical Summary

Problems solved by technology

Pressure differential fertilization tanks are simple to manufacture, low in cost, and do not require additional power equipment, but the concentration of fertilizer solution varies greatly, the frequency of adding fertilizer is frequent, and the water delivery network has a certain head loss

The Venturi fertilizer suction device is simple in structure, easy to use, and low in cost, but the water head loss is relatively large

Piston and diaphragm fertilizer injection pumps are small in size, easy to use, and easy to control the fertilization concentration, fertilization amount and fertilization time, but its mechanical sealing and manufacturing precision require high reliability, and it requires high reliability of vulnerable parts such as springs and reversing mechanisms. and durability, equipment investment is relatively high
