Environmental protection trunk liquid-injection guiding device

Abstract

The invention discloses a trunk liquid injector, which aims to provide a trunk liquid injector capable of avoiding the chemical injury during the drug application and being recycled and reutilized with environmental protection. The trunk liquid injector has a long conical drug injection nozzle; the bottom of the drug injection nozzle is connected with a drug liquid introduction seat; an internal thread structure for connecting and fixing a drug storage bottle is arranged on the inner wall of the drug liquid introduction seat; self tapping threads are arranged on the circumference of the drug injection nozzle; a film pricking device is arranged inside the drug liquid introduction seat and is formed by a plurality of flaps which has enough hardness and enclose into a cone; and the conic vertex of the film pricking device is positioned on the central axis of the space inside the drug liquid injection introduction seat. The trunk liquid injector is mainly used for the injection and introduction of the drug liquid for preventing and controlling tree diseases and insect pests, as well as injecting and importing drug liquid when fertilizer and element are deficient.

Description

Technical field: [0001] The invention belongs to the field of biological control, and in particular relates to a tree trunk liquid injection introducer. Background technique: [0002] The trunk liquid injection introducer is used for the prevention and control of tree diseases and insect pests and the injection and introduction of medicinal liquid when there is a shortage of fertilizer and nutrients. It is generally used in conjunction with the storage bottle. Sexual juice-sucking pests, borer pests, vascular bundle diseases and gall-forming pests, etc., are difficult to be effectively controlled by conventional methods. Especially for piercing and sucking mouthparts pests, such as scale insects, aphids, red spiders, and hidden pests such as weevils, longhorns, etc., conventional spraying is not easy to spray or it is impossible to have effective contact with pests. Play a better control effect. [0003] The existing trunk liquid injection introducer disclosed is basically...

Problems solved by technology

Although the above-mentioned liquid injection introducers can meet the requirements of the trunk to introduce liquid injection, the above-mentioned liquid injection introducers have some disadvantages: such as the introducers are mostly disposable products, even if the medicine is used on the same tree next time, it must be re-drilled. hole, re-use a new injector, which not only causes a lot of waste of labor and materials, but also increases the cost, and because repeated drilling causes more wounds on the tree body, the damage to the tree is relatively large; The injection nozzle (injection introducer) of some tree trunk injectors is basically a tube with a smooth surface, which is not in close contact with the tree body. Therefore, during the process of spraying or long-term injection, especially When the transpiration of the tree stops or is very weak (such as night, rainy day), the speed of the medicinal liquid entering the tree is relatively slow, and the gap between the tree body and the injector is gradually increased under the corrosion of the medicinal liquid, thereby Leakage of the medicinal solution occurs. During this process, the tree tissue around the injection hole will be completely immersed in the medicinal solution. When the medicinal solution soaks into the cambium tissue, it will cause damage to the cambium tissue, thereby seriously affecting Growth of trees, resulting in phytotoxicity around injection holes
