Abstract

The invention discloses a specialized injector for municipal landscaping and an application method thereof. The injector includes a syringe needle. The syringe needle comprises a needle tube and a needle point. The needle point is provided with a plug, one end of the plug is a coupling end capable of being connected with the needle tube and the other end of the plug is a sharp felting needle. A barb in the opposite direction of the felting needle is arranged on the plug. During utilization, through cooperation of plugging between the plug and the syringe needle, the plug can plug up the mouth of the needle tube when a tree is inserted. After the plug arrives at a preset position, the syringe needle is slightly pulled out backwards. Because of the barb, the plug is fixed, and the syringe needle moves backwards. Thus, the plug and the needle tube are separated. Then, injection is carried out, which successfully solves the problem that the syringe needle is plugged up when the tree is inserted and greatly increases work efficiency.

Description

technical field

[0001] The invention relates to municipal landscaping, in particular to a special liquid injector for municipal landscaping and a using method thereof. Background technique

[0002] The method of injecting medicinal liquid to trees to prevent and control diseases and insect pests is a new plant protection technology that has emerged in recent years; not only that, it can increase production in the aspect of nutrient fertilization of fruit trees, and can improve the survival rate in transplanting large trees. It can be used in the aspect of rejuvenation and life extension of ancient trees, and it can also be used in the aspect of anti-insect and anti-corrosion of ancient wooden buildings.

[0003] When injecting trees, the needle of the existing syringe has a straight tube structure. After the needle penetrates into the tree, it is easy to be blocked by the tree, resulting in failure to transport the liquid medicine normally. Therefore, the needle structure of...

Examples

Embodiment 1

[0031] Embodiment 1: as Figure 1 to Figure 3 As shown, a special injector for municipal landscaping includes a needle head 1, the needle head 1 is divided into a needle tube 11 and a needle point 12, a plug 2 is provided at the needle point 12, and one end of the plug 2 is a plug that can be inserted into the needle tube 11 The connecting end 21 and the other end are sharp needles 22 , and the plug 2 is also provided with barbs 23 opposite to the needles 22 . The side wall of the needle point 12 is provided with a waist groove 121, the length direction of the waist groove 121 is consistent with the axial direction of the needle tube 11, the barb 23 is inserted into the waist groove 121 to form a sliding connection with the waist groove 121, and the barb 23 penetrates Pass through the waist groove 121 and protrude from the outer wall of the needle point 12, and set the barb 23 on the plug 2 in the waist groove 121 of the needle point 12, so that after the injection is complete...

Embodiment 2

[0034] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 lies in the waist groove 121, such as Figure 6 shown, combined with figure 2 In Embodiment 2, the width of the waist groove 121 near the needle tip 12 is smaller than the width at the other end, and the barb 23 forms a transition fit or an interference fit with the minimum width of the waist groove 121 . When the needle 1 moves back slightly, the barb 23 is clamped with the narrower end of the waist groove 121, and the plug 2 is more firmly connected to the needle 1 when it is pulled out. In addition, it also provides a supporting force for the needle 1 to prevent The needle is pressed against the plug 2 once and combined with it.
