Because the utility model utilizes the thread of the needle, the needle is capable of being rotated into the tree crop, the clearance and the injection hole on the needle, thus ensuring that the injection channel is not blocked during the process of rotating the needle into the tree crop, so that the utility model has an excellent anti-leakage and anti-blocking function.
Description
Technical field
The utility model relates to and a kind of tree crop is carried out the syringe needle of injection, relates in particular to a kind of tree crop injection needle with anti-leak and anti-clogging function.
Background technology
Along with socioeconomic continuous progress and development, all trades and professions are more and more paid close attention to the availability of resource and are imitated speed, correspondingly, in agriculture field, to aspects such as tree crop fertilising, spray medicine, diseases and pests controlling, plant personnel is to the availability of resources such as medicine, fertilizer and imitate also unusual attention and care of speed; Meanwhile, plant personnel is the importance of concern for the environment protection also, makes that man and nature coordinate, the development of harmony.At present; the way of plant personnel is directly inputted into resources such as the needed medicine of tree crop, fertilizer in the tree crop body by injection device exactly; make tree crop to carry out absorbing fast and fully to resources such as medicine, fertilizer; thereby improve the availability of resource and imitate speed; and reduced the waste of resource, and then protected environment.
Crops need constantly nurse one's health at aspects such as nutrition, damage by disease and insect and protect, and the fertilising application method of traditional tree crops such as fruit tree is to take root district soil to execute and foliage-spray.The trunk injection method can effectively solve tree crop such as fruit tree and absorb the problem that the untimely conventional fertilizer application application method such as unbalanced of difficulty, trace element compensation cann't be solved because of the big generation fertilising of tree height dispenser difficulty, the sick tree of weak tree, to promote and to ensure that tree crop such as fruit tree grows.The trunk injection method is exactly in the boring of the suitable location of trunk, in the medicament hand-hole, the required conditioning liquid of tree crop is sent to the method for tree crop desired area by xylem inner catheter etc.But there is the syringe needle situation such as not in place of often stopping up, infuse in trunk injection method infusion set in operating process, and causes conditioning effect not reach intended purposes.
At present, the syringe needle that is applied on the injection device in the trunk injection method mainly comprises needle body, holding part and external portion, the holding area is between needle body and external portion, and described syringe needle also has the injection canal for the parenteral solution circulation that runs through needle body, holding part and external portion.When tree crop the state of an illness occurs or lacks nutriment, need inject corresponding medicine, fertilizer to tree crop, need push the needle body of syringe needle or beat in the tree crop body this moment by external force, by in the tree crop injection device, carrying medicine, the fertile tree crop of giving, spray medicine, fertile availability and the rate that takes effect raising much than traditional sprayer that passes through to tree crop so then with external catheter that links to each other and be connected of syringe needle with injection canal.But be applied to the following defective of syringe needle ubiquity on the injection device on the market: (1) needle body directly inserts and causes easily in the tree crop that needle body place injection canal stops up, and makes injection be not easy, thereby needs to increase the pressure of injection device; (2) because syringe needle relies on external force to be inserted in the tree crop body, when inject to tree crop, in the tree crop body liquid of injection easily along needle body toward the external leakage of tree crop, thereby the waste resource and influences result of treatment to tree crop.
Therefore, be badly in need of wanting a kind of and have anti-leak and anti-clogging function, and can effectively improve the tree crop injection needle of resource utilization and effect speed.
The utility model content
The purpose of this utility model is to provide a kind of have anti-leak and anti-clogging function, and can effectively improve the tree crop injection needle of resource utilization and effect speed.
To achieve these goals, the utility model provides a kind of tree crop injection needle, be applicable on the carrier pipe that is connected the tree crop injection device, described tree crop injection needle comprises the holding part, external and needle body, the rear end of described needle body is connected with described holding part one end, the described holding part other end is connected with described external one end, described external the other end is connected with carrier pipe, described needle body, holding part and external portion are integral structure, described tree crop injection needle has the described external portion of running through, the injection canal for the parenteral solution circulation of the rear end of holding part and needle body, wherein, described needle body is provided with the needle body screw thread outward, also dig on the described needle body slit is arranged, described slit is communicated with described injection canal, the tapered structure of the front end of described needle body, described pyramidal structure forms needle point, also offers the injection orifice that is communicated with described injection canal on the described needle point.
Preferably, an end of the holding part that is connected with described needle body is truncated cone-shaped; The holding part that is truncated cone-shaped by an end, in the time of in the tree crop injection needle inserts the tree crop body, the slit that can contact with tree crop the needle body of tree crop injection needle seals, prevent that parenteral solutions such as medicine that carrier pipe transports, fertilizer from leaking from the slit, thereby improve the availability of parenteral solutions such as medicine, fertilizer.
Preferably, described holding part is polygon; By described polygonal holding part, be convenient in the needle body insertion tree crop body of operating personnel with the tree crop injection needle.
Preferably, described injection orifice is opened between the adjacent needle body screw thread on the needle point; It is simple to make injection orifice offer technology so on the one hand; On the other hand, because the hole that needle point upper pin screw thread produced when piercing tree crop is bigger than former needle point, thereby make to be opened in when injection orifice is in needle point is rotated into the tree crop body on the needle point not blockedly, guarantee that effectively the tree crop entry needle works first watch reliably.
Preferably, described slit is dug on described needle body along the axial of described needle body; By on described needle body, offering the slit, widened the approach of the injection canal of tree crop injection needle to the tree crop injection, make that the injection of tree crop injection needle is easier, prevent that more effectively the tree crop injection needle from stopping up, guarantee that the tree crop injection needle is safer, work more reliably.
Compared with prior art, because the utility model utilizes the needle body screw thread of described needle body outer surface, make needle body can be rotated in the tree crop body apace, and closely cooperate with tree crop, prevent that parenteral solution is outside needle body leaks into tree crop, described needle body is provided with the slit and described taper needle point is provided with injection orifice at the conical surface at outer surface, injection canal can be not blocked in being rotated into the process of tree crop to have guaranteed needle body, and increased injecting pathway and the injection point of the utility model to tree crop, make tree crop can fully and fast absorb parenteral solution, thereby make the utility model tree crop injection needle have excellent anti-leak and anti-clogging function, and can also effectively improve resource utilization and imitate speed.
