Abstract

The utility model provides an automatic drip irrigator for plant for injecting liquid fertilizer into roots of plants, comprising a container, a flexible tube, a valve gate and a drip tube which can be conveniently inserted into soil. Besides, the automatic drip irrigator for plant also comprises a flow divider for enlarging the drip irrigation surface and a sensor which is capable of automatically controlling the opening and closing of the drip tube according to the growth requirement of plants or the dryness and wetness degree of soil.

Description

Automatic drip irrigator for plant

The utility model be a kind of be used for liquid fertilizer inject plant root from the animals and plants drip irrigation emitter, be fit to especially irrigation and the cultivation of family potted flower of general crops.

Usually the irrigation method of plant has three kinds: the one, and the manual watering; The one, the irrigation canals and ditches gravity irrigation; Also having a kind of then is to spray by aqueduct.Yet manual watering's labour intensity is big, irrigation canals and ditches are irrigated then must have abundant water source, and the construction cost of sprinkling irrigation is too high, and above-mentioned three kinds of modes all have the big shortcoming of water resource waste amount, and most of water has all gone down along soil gap seepage, and what in fact absorbed by crop root only is seldom a part, if use liquid fertilizer then lose bigger, and when using the fertilizer of the system of macerating, have one unpleasant foul smell in air, to distribute serious environment pollution.So people have expected this new mode of drip irrigation, for example the portable adjustable siphon drip irrigation appliance introduced of patent documentation CN86202137 is exactly wherein a kind of, thereby the shortcoming that the coring part of using it liquid fertilizer directly can be injected plant has avoided above-mentioned other irrigation method to keep away, yet this kind device can not multi-use promptly can not be irrigated the above several strain plants of two strains simultaneously, therefore will increase equipment investment, can not execute filling automatically again, must expend more manpower, and to not defence of air pollution.

The purpose of this utility model provides a kind of drip irrigation emitter that can realize automatic irrigation according to the plant growth needs, and this drip irrigation emitter decapacitation is directly watered water or liquid fertilizer and is filled in plant roots, thereby reduces outside the seepage, can also realize that dropper opens and closes automatically.

Solution of the present utility model is: have one can hang over the container that is higher than plant root, fills water or liquid fertilizer, be mounted with flexible flexible pipe in its bottom, be connected to a current divider on the flexible pipe, but by the some tributaries of current divider scion grafting flexible pipe, be equipped with a valve of regulating discharge on each root flexible pipe, tube end is equipped with a sensor, and the sensor lower end is equipped with the hard dropper of a band pore again.The crotch of being convenient to hang also is housed on the said vesse, and is furnished with lid with good seal performance, container is made of plastic, and slightly larger Plastic Drum, wooden barrel, metal drum, thick plastic bag etc. are also alternative, but in its bottom a hole of mating with hose coupling must be set.Because the utility model has been installed sensor on dropper, so can be by the drip irrigation of ground moistening degree realization according to the plant growth needs.Again owing to adopted current divider and hook and seal cover, but multi-use is not only saved equipment investment, and this drip irrigation emitter also has in the use and carries and hang conveniently, and no stink from leakage does not promptly have environment and air-polluting characteristics.

The contrast accompanying drawing is described in detail a kind of embodiment of the utility model from the structure of animals and plants drip irrigation emitter below.

Fig. 1 is a schematic diagram of the present utility model, and wherein (1) is that container, (2) are dropper for elastic film pipe, (11) for rigidity joint, (12) for gauge head, (10) for sensor box, (9) for valve, (8) for current divider, (7) for flexible pipe, (6) for joint, (5) for lid, (4) for hook, (3).

The utlity model has the water container of (3) with cover, lid (3) has excellent sealing performance, the bottom of container (1) is equipped with a joint (4) and is connected a flexible pipe (5) thus, at the other end of this root pipe each root that a current divider (6) telling being housed then divides a valve (7) is housed again on the pipe, end at minute pipe connects the dropper (12) that can conveniently insert soil, divide the junction of pipe and dropper (12) that one section elastic film pipe (10) is housed again, on film tube (10), be with a sensor box (8), in box (8), the gauge head of being made by the porous cork (9) is housed around being in charge of of flexible pipe (5) with dropper (12) junction, on the flexible pipe (5) between gauge head (9) and the above-mentioned junction, being positioned at the film tube centre has a rigidity joint (11).For the ease of carrying and hanging, container (1) also has a hook (2).

When the utility model is used for that plant carried out drip irrigation, at first with hook container is hung over the place that is higher than the plant root, filled with water in container can be dissolved in the required agricultural chemicals of plant, chemical fertilizer etc. in the water then, also can directly macerate to be shaped on the machine liquid fertilizer in container.Open valve (7), water or liquid fertilizer will flow out from dropper (12) the plant root is carried out drip irrigation, when soil abundant when gentle, the porous cork gauge head (9) of sensor is also by gentle and expand, but owing to be subjected to the restriction of sensor box (8), rigidity joint (11) in the inside compressed film pipe of cork gauge head (10) that expands and this pipe, the gap of reserving between rigidity joint (11) and the film tube (10) is stopped up, continued drop of liquid down thereby stop dropper (12).When the soil desiccation is a plant when needing moisture content, porous cork gauge head returns to reset condition again, and film tube is opened and reworked.

This drip irrigation emitter can connect many branch pipes as required, also can change the current divider of more pipes, and fixing large-scale container is set, and large-area plant is carried out drip irrigation.
