Abstract

The utility model discloses an automatic injecting needle for fruit trees, the needle case of which is similar to the general medical injecting needle head; a special needle core is arranged in the needle case; the needle core acts the function of the capillary pipe; after the needle core is contacted with the xylem of the fruit trees, the medicine agent in a medicine bottle can be absorbed by the fruit trees; the fruit trees can be rapidly supplied the lacking micronutrient element, etc., and the supply of the micronutrient element is free from the limits of the factors, such as the soil, etc. The plant growth regulating agent can be also supplied, and simultaneously, the fruit trees can be injected the internal absorbing agricultural chemical for the prevention and cure of the pest and disease damage, and the automatic injecting needle for the fruit trees can not pollute the environment.

Description

Automatic injecting needle for fruit tree

The utility model relates to a kind of entry needle, particularly a kind of automatic injecting needle that can be applicable to the fruit tree trunk.

Also there is not at present a kind of energy to give the entry needle of fruit tree microelement-supplementing etc. simple and effectively.In China North China Plain and limy soil area, northwest, commodity trees such as fruit tree are often for want of micro-, physiological disturbance occurs and the underproduction, and the effect that trace element fertilizer is used in the orchard is often not lasting.As yellowtop of apple etc., and use the very big restriction that trace element fertilizer yet is subjected to soil environment, even by the little fertilizer of plant foliage-spray, under the situation of southern tropical area of heavy rainfull of China and the cured matter trees of blade, the effect that sprays little fertilizer is also bad.If can pass through the trace element of injecting method supply fruit tree some etc. in above-mentioned area, the fruit tree of developing the economy there is huge practice significance, and the gravity injection of common use, even perhaps adopt the method for high-pressure injection, its effect is also very undesirable.

Task of the present utility model be to design a kind of simple in structure, profile is small and exquisite, easy to use, the fruit tree automatic injecting needle that can reuse in time replenish required trace element for fruit tree or carry out the extermination of disease and insect pest so that use injection to fruit tree injection growth regulator and interior suction agricultural chemicals.

The utility model is finished in the following way: at first produce the pin shell, the pin shell is made up of needle body and pin base, and the profile of pin shell and structure can similar common syringe needles or directly used commercially available syringe needle.In the inside of needle body nook closing member is set then, nook closing member can suitably stretch out needle body makes it have certain length to expose in the needle body part.The most handy stainless steel of pin shell is made, and also can use the plastics die cast.Nook closing member can be one or several capillary, preferably adopts the capillary of semipermeable membrane, also can replace with stainless steel wire.For improving automatic injection effect, should bore gas port in the pin base portion position of pin shell, the controllable diameter of gas port can be inserted the wireway that one section external diameter and gas port diameter match in gas port built in about 1mm.

The accompanying drawing given below by embodiment is described in further detail.

Fig. 1 is the schematic diagram of a kind of concrete structure of the utility model.

With reference to Fig. 1, the pin shell is made up of needle body (1) and pin base (2), in fact this pin shell is exactly commercially available syringe needle, needle body (1) is a thin and long body, in order to insert in the plant corpus, pin base (2) is used for connecting with flask for medicinal preparations (6), needle body (1) inside is provided with the nook closing member of being made up of the capillary of semipermeable membrane (3), the internal diameter capillaceous of this semipermeable membrane is about 200 μ m, wall thickness is about 10 μ m, be drilled with a gas port (4) at pin base (2) near the position of needle body (1), insert one section wireway (5) in the gas port (4), said wireway (5) adopts the polytetrafluoroethylene (PTFE) of hydrophobic to make.Above-mentioned pin shell and the available plastics of flask for medicinal preparations (6) are cast into one.

Medicament bottleneck at the contain medicament is installed a fruit tree automatic injecting needle, and when needle body inserted the xylem of fruit tree, capillary just contacted with xylem, and the medicament in the flask for medicinal preparations just can constantly automatic supply fruit tree like this.

Press needle method: make a call to earlier an aperture with the same thickness of needle body on the fruit tree stem, be deep to the xylem of trunk, aperture should have certain angle, is as the criterion so that flask for medicinal preparations can slightly be upturned.As at branch or in the root injection, should make flask for medicinal preparations and ground keep vertical as far as possible, the direction of aperture should be pointed to the center of stem.The needle body of fruit tree automatic injecting needle is inserted among the aperture of accomplishing fluently, when occurring in the flask for medicinal preparations turning on the minute bubbles, illustrate that fruit tree is at the absorption medicament.Executing pin period is good with the fine day that plant is in vegetative period because big in transpiration fine, plant, so can absorb quickly in the flask for medicinal preparations for the injection agent.

The utility model is simple in structure, easy to use, can be promptly replenish the trace element that lacks etc. to fruit tree, and not limited by the environmental factors such as soil, it can also be injected to fruit tree and inhale agricultural chemicals in some simultaneously, the anti-worm of curing the disease is to the harm of fruit tree, and tool soup utilization rate height, the advantage such as free from environmental pollution.
