Abstract

The utility model relates to an additional liquid fertilizer device, which is composed of a pressure rod, a coupled rod, a needle tube and a compression assembly, wherein, the pressure rod is connected with the upper part of the compression assembly, and can rotate; the coupled rod is connected with the pressure rod and the compression assembly, the needle tube is composed of a needle head with a plurality of holes and a needle head seat provided with a by-pass cavity, wherein, the needle head seat is fixed on a cap at the lower end of the compressing assembly, and a liquid overflowing interface of the cap at the lower end of the compression assembly is connected with a by-pass joint of the needle head seat by a connecting tube. The utility model has the advantages that the traditional additional fertilizer mode is altered, the defects that root is damaged in fertilization, loss of fertilizer is serious, fertilization is not suitable for carrying out in dry day, etc., are avoided, the fertilizer is saved, investment is reduced, the utilization of the fertilizer is enhanced, and the precocity of plants is promoted; the utility model has the drought resisting effect.

Description

A kind of liquid fertilizer placement drill

The utility model relates to a kind of liquid fertilizer placement drill, belongs to a kind of in the small farm utensil.

At present, the widely used traditional topdressing method of peasant is the spray-type fertilising or the filling type fertilising of digging pit, the sprinkling chemical fertilizer often causes the waste of fertilizer, and the filling type fertilising of digging pit easily causes the root of hindering of crops, this is because the back of topdressing is if meet not rainfall in several days, and the fertilizer that appends not only is difficult for being absorbed effectively by plant, and the fertilizer that appends produces plant roots and burns, in addition, dig pit filling type fertilising also expends more man power and material.

The purpose of this utility model provides a kind of liquid fertilizer placement drill, to solve the shortcoming that crops are sprayed insecticide and dig pit and exist in the fertilising, so that save fertilizer and make fertilizer effectively by crop absorption, has the effect of saving water conservancy, water filling drought resisting simultaneously.

The technical solution of the utility model is to be made of depression bar, trace, needle tubing and capsule-type compression assembly, the upper end cap of compression assembly has bypass cavity and feed liquor interface, lower endcaps has bypass cavity and goes out liquid interface, place in the cavity of upper end cap, lower endcaps by wearing the one-way sealing valve that pin, spring, sealing-plug serial connection constitute, in the capsule-type two ends of cover, overcoat respectively with upper end cap, lower endcaps socket, the junction seals with sealing ring; Needle tubing is made of porous syringe needle and the needle holder that has bypass cavity and joint, and syringe needle is installed on the needle holder, and needle holder is threaded with the lower endcaps of compression assembly; Tube connector one end links to each other with the liquid interface that goes out of compression assembly lower endcaps, the other end links to each other with the bypass cavity joint of needle holder: in the both sides of compression assembly, symmetry is installed the force application part of being made up of depression bar, trace, concrete structure is: pivot pin is connected the lower end of depression bar on the needle holder, depression bar can rotate around pivot pin, depression bar top is connected with pivot pin with an end of trace, and the other end of trace is connected with the upper end cap of pivot pin with the compression assembly, and trace can rotate around pivot pin.

The utility model has the advantages that and change traditional fertilizing type, avoid shortcomings such as traditional fertilization is slandered root, fertilizer loss is serious, should not apply fertilizer dry days, spray-type fertilising waste fertilizer, time saving and energy saving, available agricultural machinery is done power, save fertilizer, reduce investment, can improve the direct absorption of plant, promote the precocity of plant fertilizer, concurrently injected water can prevent the plant arid, and it is fertile to utilize motor vehicle or animal-drawn vehicle to draw water to annotate in fertilising.

Below in conjunction with Fig. 1, Fig. 2, Fig. 3 the utility model is described in detail:

The technical solution of the utility model is to be made of depression bar 15, trace 16, needle tubing and capsule-type compression assembly 1, the upper end cap 2 of compression assembly 1 has bypass cavity and feed liquor interface 7, lower endcaps 3 has bypass cavity and goes out liquid interface 8, place in the cavity of upper end cap 2, lower endcaps 3 by wearing the one-way sealing valve that pin 9, spring 10, sealing-plug 11 serial connections constitute, in the capsule-type two ends of cover 12, overcoat 13 respectively with upper end cap 2, lower endcaps 3 sockets, the junction seals with sealing ring; Needle tubing is made of porous syringe needle 5 and the needle holder 6 that has bypass cavity and joint, and syringe needle 5 is installed on the needle holder 6, and needle holder 6 is threaded with the lower endcaps 3 of compression assembly 1; Tube connector 4 one ends link to each other with the liquid interface that goes out of the lower endcaps 3 of compression assembly 1, and the other end links to each other with the bypass cavity joint of needle holder 6; Both sides at compression assembly 1, symmetry is installed the force application part of being made up of depression bar 15, trace 16, concrete structure is: pivot pin 19 is connected the lower end of depression bar 15 on the needle holder 6, depression bar 15 can rotate around pivot pin 19, depression bar 15 tops are connected with pivot pin 17 with an end of trace 16, the other end of trace 16 is connected with the upper end cap 2 of pivot pin 18 with compression assembly 1, and trace 16 can rotate around

pivot pin

17,18.

When the depression bar 15 that is positioned at compression assembly 1 both sides inwardly promotes, because the distance that two depression bars are 15 shortens, make two traces 16 oblique mobile down, thereby extruding capsule-type compression assembly 1, the liquid fertilizer injection that capsule-type compresses in the assembly 1 is underground, and when unclamping depression bar 15, the one-way sealing valves in the lower endcaps 3 of compression assembly 1 seal the lower end, under the effect of suction, liquid fertilizer is sucked from inlet 7.

But pallet 20 of lower end one injection moulding of above-mentioned needle holder 6 can limit the device that topdresses and insert the underground degree of depth, and is dark excessively when the device of avoiding topdressing inserts earth.
