Abstract
The utility model discloses a harmful insect stem borer-preventing injector, which is composed of a non-return valve [1], a needle tube [2], a needle core [5], a spring [4], and a spring shield [3]. The harmful insect stem borer-preventing injector is made to improve the prevention and cure efficiency, save the physic liquor, and reduce the environmental pollution.
Description
The utility model belongs to the forest protection apparatus, particularly kills the syringe of trunk borer.
To the control of trunk borer, generally adopt No. 7 type sprayers of workers and peasants of backpack or motor-driven high-pressure sprayer that trunk spray medicine is prevented and treated at present.Because the larva and the worm's ovum of trunk borer are hidden under xylem or cortex, it is deadly with stomach toxicity to be difficult for being tagged by soup.Therefore, control efficiency is poor.In addition, liquid waste was serious when control was done in spray, and contaminated area is big, influence ecological environment.
The purpose of this utility model is a kind of control efficiency height of design, has both saved soup, reduces the syringe of killing trunk borer of environmental pollution again.
This syringe is made of reverse stop valve, needle tubing, nook closing member, spring and spring shield.
Describe in detail below in conjunction with accompanying drawing.
End at needle tubing (2) connects reverse stop valve (1), and reverse stop valve (1) can be made up of valve seat with centre bore and globe disk.A side that faces toward needle tubing (2) chamber at valve seat is equipped with alignment pin, prevents that globe disk from falling in the needle lumen.Be processed with the circular hole littler at the tip of needle tubing (2) than lumen diameter.The nook closing member of tubulose (5) passes from circular hole.The end face sealing of the end of nook closing member (5), the side is porose, and there is straight hole at its tip.There is flange at middle part at nook closing member, is overlapping spring (4) on the nook closing member (5) between the tip of flange and needle tubing (2).Tip at needle tubing (2) is processed with external screw thread, connects spring shield (3) on it.The other end of spring shield (3) has circular hole, and nook closing member (5) can therefrom pass, but the flange on the nook closing member (5) can not pass from the circular hole of spring shield (3), like this, can guarantee that nook closing member (5) is unlikely from needle tubing (2) to come off.
During use, this syringe is docked with workers and peasants' 7 type sprayer woven hoses with woven hose (plastic tube, copper pipe, sebific duct).After the soup in the sprayer is subjected to the certain pressure effect, enter in needle tubing (2) chamber by woven hose, reverse stop valve (1), when the trunk cortex is thrust at the tip of nook closing member (5), when promoting needle tubing (2), nook closing member (5) begins to compress spring, and in needle tubing (2) chamber, slide, when the terminal side opening of nook closing member (5) enters in needle tubing (2) chamber when contacting with soup, the pressure of needle tubing (2) chamber inner liquid medicine increases, reverse stop valve is closed, and stops soup to reflux, so, soup is by the side opening of nook closing member (5), and nook closing member hollow channel and most advanced and sophisticated straight hole spray.After stopping the pushing to needle tubing (2), nook closing member (5) moves to the terminal side opening of normal position nook closing member (5) and is sealed by the most advanced and sophisticated circular-hole internal-wall of needle tubing (2) under the effect of spring (4), and soup stops to spray.Simultaneously, because the pressure of sprayer inner liquid medicine is greater than the pressure needle tubing (2) chamber in, so, reverse stop valve (1) unlatching, soup adds to again in the needle tubing (2).
In order to prevent the tip bending of nook closing member (5), be processed with screw thread at its tip, in addition, a syringe needle (7) that has a flange is connected the tip of nook closing member (5) by normal female pin cap (6), the end of syringe needle (7) has straight hole, communicates with nook closing member (5), most advanced and sophisticated end face sealing, the side perforate is in case the needle point hole is stopped up by foreign material such as barks.
In order to prevent that soup from from gap overflow between the most advanced and sophisticated circular hole of needle tubing (2) and the nook closing member (5), can add a sealing ring at the tip of needle tubing (2).
This syringe can be with metal material or plastics manufacturing.
When using this syringe to preventing and treating trunk borer, owing to adopt long woven hose to be connected with workers and peasants' 7 type sprayers, so can facing the insect of 5～6 meters high trunks with standing in, the control personnel carries out the injection control, like this, the hardship and the workman that move terraced orange forced labour when not only having exempted artificial slotting stifled worm channel control climb the trunk unsafe factor, and, the prevention effect height Save soup, environmental contamination reduction.
Claims (3)
1, a kind of syringe of killing trunk borer is characterized in that it comprises reverse stop valve [1], needle tubing [2], nook closing member [5], spring [4], spring shield [3].
2,, it is characterized in that it also comprises syringe needle (7), pin cap (6) according to the said syringe of claim 1.
3,, it is characterized in that between the circular hole at the tip of needle tubing (2) and nook closing member (5), sealing ring being arranged according to the said syringe of claim 1.
