Slanted outlet infusion set for trees

Abstract

The invention discloses a slant-liquid-outlet infusion apparatus for trees. The slant-liquid-outlet infusion apparatus is characterized by comprising a needle head and a pressing plate. A flow passage extending towards the front end is formed in the needle head. The front end of the flow passage is plugged to form a conical head. A slant liquid outlet seam is formed in the side wall of the side, close to the conical head, of the flow passage, wherein a 45-degree included angle is formed between the axis of the flow passage and the slant liquid outlet seam. An annular connector is connected to the back end of the flow passage and internally provided with a platform perpendicular to the flow passage. A hose connector is arranged on the lateral side of the annular connector. The pressing plate is connected to the open side of the annular connector in a sealed mode. Protrusions distributed around a back end opening of the flow passage are arranged on the platform and abut against the inner face of the pressing plate. By means of the slant-liquid-outlet infusion apparatus, fibers of tissues of tree trunks can not be cut off, later-period wound healing and later-period wound growing are facilitated, and a hole can not be plugged; when the slant-liquid-outlet infusion apparatus is used, force can be transmitted to the needle head by pressing the pressing plate through the protrusions, and therefore the needle head can be more easily punctured into the tree trunks.

Description

technical field [0001] The invention relates to an infusion appliance in the field of tree and plant protection, in particular to an infusion appliance with an oblique liquid outlet for 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 ...

AI Technical Summary

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.

The closest prior art patent document (publication number CN202396209U) discloses a new type of tree infusion needle, which consists of a needle tube and a needle head. There are many round infusion holes on the lower part of the needle tube. After the trunk, the tree fibers are easy to stay and block at the round infusion hole, blocking the infusion hole and affecting the infusion. The round infusion hole forms a small recessed gap on the surface of the needle tube, which will also scrape the tree fibers to break and damage them when inserted. Point type Permeation diffusion area is small

The prior art also has a patent document (publication number CN203027784U) disclosing a tree-adjustable infusion needle. The front end of the tree-adjustable infusion needle is circumferentially distributed with strip-shaped liquid outlets whose direction is consistent with the axis of the flow channel. A large liquid outlet area can only extend the liquid outlet. Since the extrusion force of the tree fiber is relatively large when inserted into the tree, if the strip-shaped liquid outlet is made too long, it will be squeezed and deformed by the tree fiber. Such a needle structure is strong. Low, affecting infusion penetration
