Abstract

The utility model relates to a liquid fertilizer applicator which can apply liquid fertilizer or the aqueous solution of easily soluble solid fertilizer to the soil of the roots of the crops and is particularly suitable for the economic crops covered by mulching films. The device solves the defects of the crop fertilizer application in the prior art, and in particular solves the defects of the fertilizer application for the crops covered with mulching films. The device needs to be matched with a sprayer to be used. A main body (2) is arranged on the spraying tube (13) of the sprayer by a connector (1), a conic hole (4) is formed on the lower part of the main body (2), a rubber ball (3) is arranged in the conic hole (4), the rubber ball (3) is connected with a conic body (5), and a circular surface (12) of the conic body (5) is provided with four rib sheets (8) and four liquid discharge grooves (11).

Description

Distributing device for fertilising liquid

The utility model is the root soil to the crops in vegetative period, particularly to the crop of covering with plastic film, imposes liquid fertilizer, or the device of the aqueous solution of easily molten solid fertilizer.

This device is to economic crops such as watermelon, vegetables, fruit trees, and the crop in the greenhouse, protection ground, booth is the most suitable.Because plant all covering with plastic film of these crop majorities, and the place of planting these crops all has the water source mostly, and water intaking is convenient for easily molten solid fertilizer.

When the crops of giving vegetative period were topdressed, commonly used had three kinds of modes: the hole that, digs with a pick earlier, fertilizer then, earthing; Shortcoming is that labour intensity is big, and efficient is low.Two, directly fertile toward crop root point, with ploughing time, carry out earthing then; Shortcoming is that fertilization depth is not enough, and by lacking that crop absorbs, utilization rate of fertilizer is low.Three, to the crop of covering with plastic film,, be that an end of wooden stick is whittled into taper shape in order to protect mulch film, on the mulch film in soil jack, click and enter earthing behind the fertilizer; Its shortcoming also is that labour intensity is big, and efficient is low.

At these problems, the semi-automatic manpower fertilizer placement drill of excitation formula that Longjiang, Harbin farm implements factory produces solves these problems basically.But unsatisfactory on the effect, and, can not topdress with it to the crop of covering with plastic film.Because its can cause to a certain degree mechanical damage to mulch film, make mulch film can not give full play to coverage effect.

The purpose of this utility model is to provide a kind of, can reduce labor intensity, and raises labour efficiency; Can topdress to the crop of covering with plastic film again, and can further improve the liquid fertilizer placement drill of utilization rate of fertilizer.

What the purpose of this utility model was achieved in that on agricultural widespread usage is 16 type knapsack sprayers, shower nozzle on the sprayer jet pipe is backed out, this device and sprayer connection change the outfit, during fertilising, this device is inserted in the soil, and cone leaves conical bore to ball jack-up, outlet liquid is opened, and solution injects soil from liquid outlet groove; When extracting, under the action of gravity of the pressure of solution and cone, ball itself, ball is sealed the pass liquid outlet automatically, the control solution.

The utility model compared with prior art has five advantages: one, volume is little, convenience is suitable: overall long 12.6 centimetres of this device, the main body external diameter has only 1 centimetre, is installed on the sprayer to use.Two, can topdress to the crop of covering with plastic film: because the main body external diameter has only 1 centimetre, on mulch film, prick out such aperture, the overlay film effect is had no impact.Three, improve fertilizer utilization ratio, increase crop yield: what this device was used is the aqueous solution of fertilizer, is easy to crop after applying and absorbs; Therefore, improve fertilizer utilization ratio, also just improved crop yield.Four, raise labour efficiency; As applying fertilizer with action fast, can apply fertilizer twice each second.Five, can carry out subsoil application: because main body is thinner, external diameter slightly has only 1 centimetre, and it is little that Xiang Tuzhong inserts resistance; So can make this device of main body lengthening, to deep rooting plants such as fruit trees, can insert to deep layer, carry out subsoil application.

The concrete structure of this device is provided by Figure of description, below accompanying drawing is explained.

Fig. 1 is the profile of this device.For the type of attachment of ball and cone is expressed clearly, ball is also by dissecing drafting.Fig. 2 is a cone A-A mark to, the cutaway view that amplifies with 2:1.Fig. 3 B that to be cone amplify with 2:1 is to view.Fig. 4 is the partial enlarged drawing that amplifies with 2:1.

This device mainly is made of connector (1), main body (2), ball (3), cone (5).

Connector (1): internal thread is arranged, this device is installed on the jet pipe of sprayer (all not drawing in the installation drawing on the sprayer) with it.

Main body (2): top links to each other with connector (1), and conical bore (4) is formed at the bottom, and the bottom in hole is liquid outlet (9).

Ball (3): in conical bore (4), link to each other with cone (5).Ball among the figure (3) is in the position of closing liquid outlet (9).

Cone (5): four muscle sheets (8) and four liquid outlet grooves (11) are arranged on its disc (12), and muscle sheet (8) is gone up also has a round end (10) to insert in the ball (3), is attached thereto.

Realize that the best way of this device is performed such: the shower nozzle on the sprayer jet pipe is backed out, loaded onto this device, and tighten.Just can use in the bucket of liquid fertilizer adding sprayer.The solid fertilizer of Yi Rong is poured fertilizer in the bucket into earlier, adds water then, and is several down with the wooden stick stirring, and fertilizer is fully dissolved.The back sprayer, left hand presses depression bar, makes and pumps certain solution in the surge drum; Switch opens on the right handgrip handle, solution just in jet pipe pours this device main body (2), are pushed down ball (3) envelope and have been closed liquid outlet (9).Along direction shown in the arrow (6), this device is inserted in the soil (7) downwards, cone (5) is just ball (3) jack-up, leave conical bore (4), liquid outlet (9) is opened, and solution is between four muscle sheets (8), through liquid outlet (9),, inject soil (7) by liquid outlet groove (11).When extracting from soil (7), under the effect of the gravity of the pressure of solution and cone (5), ball (3) itself, ball (3) falls back in the conical bore (4), and envelope is closed liquid outlet (9) automatically.The external diameter of main body (2) was difficult for thick, was preferably 1 centimetre, to alleviate to the destruction of mulch film with to the influence of overlay film effect.
