Abstract
The fertilizer spraying needle for liquid fertilizer applying machine as one farm machine has a valve seat with upper and lower cavities and communication hole assembled between the needle head and the needle rod to connect the needle head and the needle rod integrally; a valve core, a pressure spring and a pressure regulating nut assembled successively inside the lower cavity. The valve core has upper conic surface contacting to the pressure regulating nut; the pressure regulating nut is screwed to the valve seat; the pressure spring has two ends contacting separately to the valve core and the pressure regulating; and the valve seat has fertilizer spraying hole communicated with the lower cavity and the outside. The fertilizer spraying needle may be used to apply liquid fertilizer into soil near the plant root system, and has the features of simple structure, reliable operation, good fertilizer applying effect and high adaptability.
Description
Technical field
The invention belongs to agricultural machinery, and the liquid fertilizer that relates generally on a kind of liquid fertilizer applying machine applies operation part.
Background technology
At present, its most important condition of the raising of crop yield is the input that depends on fertilizer.Production practices for many years, the use all the year round of solid-state chemical fertilizer makes crop yield obtain certain assurance, but chemical fertilizer ubiquitous to soil environment pollution and the following degradation problems of the hardening of destruction, soil, crop products quality also exposing gradually and manifesting, bring negative effect significantly for the mankind and living environment thereof.Use the problems referred to above that solid-state chemical fertilizer exists for overcoming, the liquid fertilizer of succeeding in developing in recent years is exactly a kind of nuisanceless, wide spectrum, efficient, Multifucntional fertilizer, because liquid fertilizer is solution or the suspension that contains two or more nutritive elements, to quickening plant growth, improve crop quality and added value, enhancing resistance, effectively improving the soil etc. remarkable result is all arranged, be subjected to the peasant and welcome.But,, liquid fertile applying is restricted because the defective of liquid fertile fertilising needle head structure design does not also have a kind of ideal and liquid fertile mechanization reliably to use facility in reality is produced.
Summary of the invention
The purpose of the invention is exactly the needs at the fertile mechanized application operation of liquid state, and design provides a kind of fertilizer spraying needle for liquid fertilizer applying machine, reaches accurate, the fertilising purpose that quality is good, operating efficiency is high of reliable, the fertile amount of liquid fertilizer fertilising operation.
The basic design of the invention is, equipped valve seat fuses syringe needle and shank between syringe needle and shank, and syringe needle and shank lay respectively at valve seat lower chambers and valve seat upper chamber one side, the centre bore of shank and upper chamber's connection; Between upper chamber and lower chambers, be provided with intercommunicating pore; At bottom chamber equipped successively from top to bottom spool, compression spring and look nut, the upper cone dignity of its spool contacts airtight cooperation with intercommunicating pore, look nut is joined the bottom chamber that is installed in valve seat by its external thread buckle and valve seat internal thread spiral-lock, and the upper and lower end face of compression spring contacts with the look nut end face with spool respectively; Be provided with fertilizer spraying needle on the valve seat sidewall bodies, the innner and outer end of this fertilizer spraying needle communicates with the lower chambers and the outside atmosphere of valve seat respectively, so far constitutes fertilizer spraying needle for liquid fertilizer applying machine.
The invention can spray liquid fertilizer near the crops root system the soil horizon easily, and simple in structure, operation is reliable, the fertilising operation effectiveness good,, applied widely, can be fitted on the fertile fertilizing equipment of various liquid state, the operating efficiency height can satisfy different liquid fertile fertilising job requirements.

Accompanying drawing is a fertilizer spraying needle for liquid fertilizer applying machine general structure schematic diagram.
Piece number explanation among the figure:
1, syringe needle, 2, look nut, 3, compression spring, 4, fertilizer spraying needle, 5, spool, 6, valve seat, 7, shank, 8, upper chamber, 9, intercommunicating pore, 10, lower chambers, 11, centre bore.
Embodiment
Below in conjunction with accompanying drawing the invention optimum implementation is described in detail.A kind of fertilizer spraying needle for liquid fertilizer applying machine, equipped valve seat 6 between syringe needle 1 and shank 7 fuses syringe needle 1 and shank 7, and syringe needle 1 and shank 7 lay respectively at valve seat 6 lower chambers 10 and valve seat 6 upper chamber 8 one sides, and the centre bore 11 of shank 7 is connected with upper chamber 8; Between upper chamber 8 and lower chambers 10, be provided with intercommunicating pore 9; Equipped successively from top to bottom spool 5, compression spring 3 and look nut 2 in lower chambers 10, the upper cone dignity of its spool 5 contacts airtight cooperation with intercommunicating pore 9, look nut 2 is joined in the lower chambers 10 that is installed in valve seat 6 by its external thread buckle and valve seat 6 internal thread spiral-locks, and the upper and lower end face of compression spring 3 contacts with look nut 2 end faces with spool 5 respectively; Be provided with fertilizer spraying needle 4 on valve seat 6 sidewall bodies, the innner and outer end of this fertilizer spraying needle 4 communicates with the lower chambers 10 and the outside atmosphere of valve seat 6 respectively.
During use, this fertilizer spraying needle is fitted on the liquid fertilizer applying machine, the centre bore 11 of shank 7 is communicated with pressure solution variable feed system on the facility.During operation, syringe needle 1, valve seat 6 and shank 7 insert in the soil, be positioned at the crop root sidepiece, solution with suitable pressure is transported in the centre bore 11 of shank 7 from pressure solution variable feed system, and enters in valve seat 6 upper chamber 8, and the pressure solution is through intercommunicating pore 9 and spool 5 compression pressure springs 3, spool 5 is broken away to be contacted with the sealing of intercommunicating pore 9, the pressure solution enters in the lower chambers 10 of valve seat 6, enters in the soil from fertilizer spraying needle 4 ejections, sprays near crop root; When pressure solution variable feed system stops to centre bore 11 supply pressure solutions, move intercommunicating pore 9 sealings on compression spring 3 effect bottom spools 5, stop to spray solution, syringe needle 1, valve seat 6 and shank 7 are extracted from soil at this moment, finish once liquid fertilizer and spray operation, so repeat.The upper and lower position of look nut 2 in lower chambers 10 adjusted in rotation, changes the extruding force of 3 pairs of spools 5 of compression spring, can realize the adjusting of liquid fertile fertilising pressure size.
