  The present invention relates to a pressure-type tree trunk injector.

  Recent developments in various industries are striking, and due to pollution and various pests, trees get sick, and various pollutants that inhibit tree growth due to soil contamination are present in the soil. There is a problem that the trees are easily debilitated by the contained pollutants.

  It is necessary to appropriately inject a chemical solution such as a suitable therapeutic agent or nutrient to prevent the damage caused by the disease and damage of the tree and the death of the tree.

  The methods for injecting chemicals to trees include foliar spraying methods that spray chemicals on the leaves of trees, irrigation methods that dilute over-chemicals in water and spray them immediately on the soil, and injecting chemicals through the perforation of trees. The trunk control method is widely used. However, it is environmentally friendly, and a reliable effect can be obtained more quickly. Therefore, the trunk control method is widely used.

  In order to inject a chemical solution into a tree using the tree trunk control method, the injection hole has a gradient of about 45 ° with respect to the surface of the tree from the surface of the tree to the inside of a predetermined depth using a drill. Form. Then, when an injection tube connected to the chemical solution container is inserted into the injection hole, the chemical solution in the chemical solution container is supplied to the tree along the injection tube, and the supplied chemical solution circulates and recirculates to the tree through the water pipe of the wood part of the tree. Absorbed.

  However, such a chemical solution injection method has a disadvantage that the injection rate of the chemical solution is slow because it depends on the suction force of the trees. In addition, there is a drawback that it is difficult to inject a chemical into a tree species such as a conifer that produces a large amount of sap.

  For these reasons, recently, a technique for supplying a drug to a tree using pressure inside a container has been proposed (for example, see Patent Documents 1 and 2 below).

  As shown in FIG. 1, the pressure-type tree trunk injector 1 according to the present invention is configured so that the chemical liquid inserted and accommodated in the perforated portion D of the tree is smoothly and quickly injected into the tree by the pressure generated inside. A pressure part 10 for generating pressure in the trunk injector 1; an upper cover 20 formed on the pressure part 10 for sealing the upper part of the pressure part 10; and formed on a lower part of the pressure part 10 for the pressure. The lower part of the part 10 is sealed, and the injection | pouring part 30 which inject | pours the chemical | medical solution discharged | emitted by pressure into a tree is provided.

  More specifically, the pressure part 10 is formed at the central part of the trunk injector 1, and is composed of a bellows tube 100 which is hollow and contains a chemical solution inside, and a plurality of bellows formed on the outer surface. When the bellows tube 100 is urged and contracted in the longitudinal direction, the pressure inside the pressure part 10 is compressed while the air pressure inside the pressure part 10 is compressed, and the chemical solution is quickly discharged by the pressure. Is done.

  At this time, the bellows tube 100 of the pressure unit 10 is easily biased and contracted. However, in order to make it difficult for the drug solution to flow backward while expanding, the bellows 100 of the bellows tube 100 as shown in FIG. -1, 100-2 to 100-n have a shape in which the upper surface and the lower surface are rounded toward the upper portion, and the height A of the upper surface is formed higher than the height B of the lower surface.

  Since each of the bellows tubes 100-1, 100-2 to 100-n of the bellows tube 100 has the above-described configuration, when the bellows tube 100 is urged and contracted, the bellows tube 100 is easily folded. -1 and 100-2 to 100-n are folded while engaging in an arc shape, and are not expanded unless the user pulls them with force, so that the pressure generated in the pressure part 10 flows backward. However, the bellows tube 100 is prevented from being arbitrarily expanded and expanded.

  The upper cover 20 surrounds the upper surface and the upper outer surface portion of the pressure portion 10 to seal the upper portion of the pressure portion 10, protects the bellows tube 100, and easily attaches the pressure portion 10. It is configured to force.

  The injection part 30 is formed at the lower part of the pressure part 10 to seal the lower part of the pressure part 10 and has a shape whose width becomes narrower as the whole progresses from the upper part to the lower part, and the pressure generated in the pressure part 10 Thus, the chemical solution accommodated inside is configured to be smoothly injected into the tree.

  The structure of the injection part 30 will be described more specifically. The injection part 30 is formed with a lower cover 32 that surrounds the outside of the lower part of the pressure part 10 and protects the lower side of the bellows tube 100. A guide tube 33 is formed at the lower end of the lower cover 32. The guide tube 33 has a shape that becomes narrower as it goes to the tip in order to facilitate the flow of the chemical solution.

  An injection tube 34 is formed at the lower end of the guide tube 33. The injection tube 34 extends in the longitudinal direction and decreases in width toward the distal end. A lid 35 is formed in the opening 340 that is the distal end of the injection tube 34. Although formed, the lid 35 is heat-sealed to the opening 340 and closes the opening 340. Therefore, the opening 340 is cut out with a knife or a scissors in use.

  The injection tube 34 is formed with a fitting guide 342 that protrudes spirally along the outer peripheral edge. When the injection tube 34 is fitted into a tree, the tree is previously drilled by the insertion guide 342 that protrudes spirally. Even if the perforation portion D is small, it is not necessary to perforate again, and no additional tool is required for fitting, and it can be turned by hand. In conventional tree trunk injectors (Patent Documents 1 and 2), when an impact is applied from the outside, the main body of the tree trunk injector is easily removed from the injection tube, and in addition, to fit the tree trunk injector into the hole of the tree A tool for applying a separate force such as a hammer was required. On the other hand, according to the pressure-type tree trunk injector 1 according to the present embodiment, when the pressure-type tree trunk injector 1 is used, it can be easily fitted into the perforated part of the tree without using a separate assembly tool. In addition, since the spiral insertion guide is used, a child or a general person cannot easily remove the pressure-type tree trunk injector 1 from the tree except for the user. .
