Description

Side-out top-in infusion insertion head for trees

Technical Field

The invention relates to an infusion device in the field of tree plant protection, in particular to an infusion insertion head for a side-outlet top-entry tree.

Background

The fruit tree planting is wide in the great country of forestry in China, along with the improvement of the planting technology, the trees are often transfused for healthy growth of the trees in the transplanting period or the key growth period of the seedlings or when diseases are generated, necessary water, nutrients or medicines are provided for the trees, so that the survival rate and the growth situation of the trees are greatly improved, the effect of yield improvement and efficiency increase are obvious, and particularly, the infusion maintenance cannot be carried out on the cultivation of some trees with high economic value, so that the infusion technology is particularly important. The existing tree transfusion is similar to human transfusion, nutrient solution or liquid medicine is input into a trunk through a needle inserted into the trunk and then is conveyed to a tree crown through tissues in the trunk, the tree transfusion is favorable for being quickly absorbed by the tree, although the existing tree transfusion means is very common, the transfusion apparatus of the existing tree transfusion apparatus also adopts apparatuses similar to the human or animal transfusion, such as bagged nutrient solution, a dropper and an injection head, the injection head is thick, the injection head is quite laborious when the injection head is inserted due to the fact that the trunk is hard, and the needle is easily blocked by the tissue fibers in the trunk, therefore, people need to drill holes on the trunk before the tree transfusion, then insert the injection needle into the holes, sometimes need to drill a plurality of holes for quick absorption, the holes are helpful for the transfusion, but the holes break and cut off the tissue fibers in the trunk, the subsequent water conveyance from the root to the tree crown is not facilitated, and nodules are easily formed at the, affecting tree growth, which still remains to be solved technically.

Disclosure of Invention

In order to solve the problems, the invention provides a side-outlet top-in type infusion insertion head for trees.

The technical scheme adopted by the invention is as follows: the utility model provides a side goes out liquid top income formula trees and inserts head with infusion, its characterized in that includes the syringe needle and presses the board, be equipped with the runner that extends to the front end in the syringe needle, runner front end shutoff forms a taper head, is equipped with circular liquid outlet on the lateral wall that the runner is close to taper head one side, and the runner rear end is connected with an annular interface, is equipped with one in the annular interface with runner vertically platform, is equipped with the hose interface on the annular interface lateral surface, presses the open side of board sealing connection at annular interface, is equipped with the arch that distributes around port behind the runner on the platform, and protruding top ends is pressing on the board inner face.

Furthermore, the liquid outlets are more than two and are uniformly distributed along the circumferential direction of the flow passage.

Furthermore, the hose connector is connected with a flow control valve.

Further, the axial length of the cone head is 0.5 cm to 1 cm.

Furthermore, the included angle formed between the conical head and the conical bottom is larger than 60 degrees.

The invention has sharp front end, can be squeezed into by tissue fiber in the trunk, but will not cut off the tissue fiber of trunk, help wound healing and growing up later stage, the liquid outlet is set up in the side of the syringe needle, will not stop up the hole, the liquid outlet can also be set up as a plurality of, improve the infusion and cover the area spread, help the liquid medicine or nutrient solution to distribute and transmit evenly, help to absorb fast too, the invention has pressing the board in the rear end of the syringe needle, can press the pressing board and transmit the force to the syringe needle through the protrusion while using, make the syringe needle prick into the trunk more easily.

Detailed Description

The embodiment of the invention is shown in figures 1 to 3, the side liquid outlet jack-in infusion insertion head for trees is provided with a needle head 1 and a pressing plate 2, the needle head is internally provided with a flow passage 3 extending towards the front end, the front end of the flow passage is sealed to form a conical head 4, the side wall of the flow passage close to one side of the conical head is provided with a circular liquid outlet 5, the number of the liquid outlets can be one or more than two, the number of the liquid outlets is ten in the embodiment, the liquid outlets are arranged in a circumferential distribution and axial distribution and are multi-point infusion, the rear end of the flow passage is connected with an annular interface 6, the annular interface is internally provided with a platform 7 vertical to the flow passage, the annular interface is connected with the rear end of the needle head through a connector 10 on the platform 7 and the platform 7, the side surface of the annular interface is provided with a hose interface 8, the side is, the platform is provided with bulges 9 distributed around the rear port of the flow channel, the bulges are propped against the inner surface of the pressing plate, the force applied on the pressing plate can be transmitted to the needle head, and the pressing plate is prevented from being deformed or broken.

The invention has sharp front end, when the invention is inserted, the invention can be squeezed into the tissue fiber in the trunk, and the tissue fiber of the trunk can not be cut off, thus being beneficial to the healing and the growth of the wound at the later stage, the liquid outlet is arranged at the side surface of the needle head, the hole can not be blocked, the multi-point input can be realized, the area of the transfusion covering and the diffusion can be improved, the medicine liquid or the nutrient solution can be evenly distributed and transmitted in the trunk, and the invention also has the pressing plate arranged at the rear end of the needle head, when in use, the pressing plate can be pressed or knocked to transmit the force to the needle head through the bulge, so that the needle head can be more easily prick.
