Spiral penetrating trees with infusion needles

Abstract

The invention discloses a transfusion needle for spiral tree penetration. The transfusion needle is characterized in that the needle comprises a needle head and a pressing plate. A flowing channel extending to the front end is formed in the needle head; a tapered head is formed at the front end of the flowing channel in a plugging mode; a spiral groove is formed in the side wall of one side, approaching the tapered head, of the flowing channel; and a liquid hole is formed in the spiral groove. An annular interface is connected to the rear end of the flowing channel; a platform perpendicular to the flowing channel is arranged in the annular interface; and a flexible tube interface is arranged at the side of the annular interface. The pressing plate is connected to the open side of the annular interface in a sealing mode. Protrusions that are distributed around the rear port of the flowing channel are arranged on the platform and are arranged on the inner side of the pressing plate in a supporting and stopping mode. According to the invention, the trunk tissue fibers are not cut; the later wound healing and growth can be realized well and no hole is plugged. When the transfusion needle is in use, the pressing plate is pressed and the force is transmitted to the transfusion needle head by the protrusions, so that the needle head can go through the trunk easily.

Description

technical field [0001] The invention relates to a device for infusion in the field of tree and plant protection, in particular to an infusion needle for spirally penetrating trees. Background technique [0002] Our country is a large forestry country, and fruit trees are widely planted. With the improvement of planting technology, when the seedlings are transplanted or in their critical growth period or when diseases occur, in order to make the trees grow healthily, it is often necessary to infuse them to provide them with the necessary water, nutrients or Drugs, thereby greatly improving the survival rate and growth trend of trees, have obvious effects on increasing production and increasing efficiency, especially the cultivation of some trees with high economic value is inseparable from infusion maintenance, so infusion technology is especially important. The existing tree infusion is also like human infusion. The nutrient solution or medicinal liquid is input into the tru...

Problems solved by technology

The existing tree infusion is also like human infusion. The nutrient solution or medicinal liquid is input into the trunk through the needle inserted into the trunk, and then transported from the tissue in the trunk to the crown, which is conducive to the rapid absorption of the tree. Although the existing tree infusion methods are already very common , but its infusion equipment does also use equipment similar to human or animal infusion, such as bagged nutrient solution, dropper and injection head, but the injection head is relatively thick, and it is very laborious to insert the injection needle due to the hard trunk, and the needle It is also easily blocked by the tissue fibers in the trunk. For this reason, people will drill holes on the trunk before giving the tree infusion, and then insert the injection needle in the hole. Sometimes multiple holes will be drilled for fast absorption. Although drilling is helpful It is suitable for infusion, but the damage of drilling cuts off the tissue fibers in the trunk, which is not conducive to the subsequent water transportation from the root to the crown. It is easy to form nodules at the drilling site and affect the growth of trees. This still needs to be solved technically.
