Abstract
The utility model discloses a novel liquid fertilizer applying and spraying needle, and belongs to agricultural machinery. A spring base, a tension spring and a valve core are sequentially arranged inside a needle body cavity from top to bottom; the spring base is fixedly arranged inside the needle body cavity; the valve core can be assembled inside the needle body cavity in a manner of moving up and down; the upper end and the lower end of the tension spring are respectively connected with the spring base and the valve core; a fertilizer inlet is formed in the spring base; a communicating hole is formed in the valve core; an O-shaped seal ring is assembled between the upper end face of a circular bead at the lower end of the valve core and the lower end face inside the needle body cavity; a fertilizer discharge hole is formed in the lateral wall of the lower side part of the needle body; a syringe needle is assembled on the upper end part of the needle body; a sealing gasket is assembled between the syringe needle and the needle body. The novel liquid fertilizer applying and spraying needle is simple and reasonable in structure, good in sealing property, low in manufacturing technology difficulty, easy to process, low in manufacturing cost, high in deep fertilization operation accuracy, reliable to use, and fewer in faults.
Description
Technical field
The utility model belongs to agricultural machinery, relates generally to a kind of novel liquid fertilizing fertilizer spraying needle.
Background technology
The operation of liquid chemical fertilizer deep placement is a kind of chemical fertilizer application new technology that starts in recent years application, compared with solid-state chemical fertilizer application traditionally, liquid fertilizer processing of having because of it is cheap, can give full play to while using chemical fertilizer fertilizer efficiency, reduce loss of chemical fertilizer loss, improve chemical fertilizer utilization ratio, reduce and use the cost of chemical fertilizer, the various features such as free from environmental pollution, liquid fertilizer mechanization is used research and is mentioned in research and development schedule.At present, a kind of liquid fertilizer fertilizer spraying needle that is similar to diesel injector structure is applied on liquid fertilizer deep placement work tool, has realized the operation of liquid chemical fertilizer pin deep placement.But such fertilizer spraying needle requirement on machining accuracy is high, manufacturing technology difficulty is large, and complex manufacturing, cost are high.
Summary of the invention
The purpose of this utility model is exactly the problem existing for above-mentioned prior art, in conjunction with the actual needs of liquid fertilizer deep placement operation, research and develop a kind of novel liquid fertilizing fertilizer spraying needle, reach the object that reduces mechanical processing difficulty and manufacturing cost, simplified manufacturing technique process, ensures fertilising operation quality.
Basic Design of the present utility model is, in needle body chamber, configure successively from top to bottom spring base, tension spring and spool, described spring base is packed in needle body chamber, and spool can be fitted in needle body chamber up or down, and the upper and lower end of described tension spring is connected with spring base and spool respectively; Fertilizer inlet is set on spring base, on spool, offers intercommunicating pore, equipped O RunddichtringO between lower surface in the upper surface of spool lower end shoulder and needle body chamber, fertilizer hole is opened on the sidewall of needle body following side; Syringe needle is fitted on needle body bottom, and between described syringe needle and needle body, equipped gasket seal, so far forms a kind of novel liquid fertilizing fertilizer spraying needle.
The utility model is simple and reasonable, good seal performance, and manufacturing technology difficulty is low, and handling ease is cheap for manufacturing cost, and deep fertilizer spraying homework precision is high, uses reliably, and fault is few.
Brief description of the drawings
Accompanying drawing is a kind of novel liquid fertilizing fertilizer spraying needle general structure schematic diagram.
Piece number explanation in figure:
1, needle body, 2, spring base, 3, fertilizer inlet, 4, tension spring, 5, spool, 6, intercommunicating pore, 7, O RunddichtringO, 8, fertilizer hole, 9, gasket seal, 10, syringe needle.
Embodiment
Below in conjunction with accompanying drawing, the utility model optimum implementation is described in detail.A kind of novel liquid fertilizing fertilizer spraying needle, in needle body 1 chamber, configure successively from top to bottom spring base 2, tension spring 4 and spool 5, described spring base 2 is packed in needle body 1 chamber, spool 5 can be fitted in needle body 1 chamber up or down, and the upper and lower end of described tension spring 4 is connected with spring base 2 and spool 5 respectively; Fertilizer inlet 3 is set on spring base 2, on spool 5, offers intercommunicating pore 6, equipped O RunddichtringO 7 between lower surface in the upper surface of spool 5 lower end shoulders and needle body 1 chamber, fertilizer hole 8 is opened on needle body 1 following side sidewall; Syringe needle 10 is fitted on needle body 1 bottom, equipped gasket seal 9 between described syringe needle 10 and needle body 1.
When deep placement liquid fertilizer uses, by liquid fertilizer, the fertilizer inlet 3 on spring base 2 enters in needle body 1 chamber fertilizer pump, now insert in soil syringe needle 10 and needle body 1 following side, the intercommunicating pore 6 of the liquid fertilizer with certain pressure on spool 5 also overcomes the pulling force of tension spring 4, spool 5 is promoted to move downwards in needle body 1 chamber, the fertilizer hole 8 of liquid fertilizer from needle body 1 injected in soil, completed once quantitatively liquid fertilizer fertilising operation.Under tension spring 4 effects, spool 5 rising return sealings, do and note fertile operation preparation, circulation according to this next time.
