[0018] (III) Beneficial Effects

[0019] This utility model provides a portable injection tool for forest tree nutrients, which has the following beneficial effects:

[0020] 1. This portable forest nutrient agent injection tool, through the setting of the injection component, allows the required agent to be placed on the inlet, and then the agent enters the syringe through the inlet. Furthermore, the microporous filter membrane body can separate air from the agent, ensuring that the agent entering the injection chamber is free of air, and preventing residual air from forming air embolisms that enter the tree and thus harm the tree's growth.

[0021] 2. This portable forest nutrient injection tool, through the setting of adjustment components, pressure plate, locking block, and locking spring, allows for easy adjustment of the injection dosage by first rotating the knob, which drives the adjustment plate to rotate within the injection cylinder. Simultaneously, the operator observes the scale lines on the injection cylinder and moves the adjustment plate to the desired injection level, thus avoiding over- or under-injection and affecting the effect. After injection, pressing the pressure plate compresses the locking block and locking spring, causing the locking block to retract into the injection needle, allowing the needle to be removed. This facilitates the use of various needle sizes for different types and thicknesses of trees, and the needles are easily replaceable, adapting to diverse injection needs and improving the tool's versatility.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4 The present invention provides a technical solution: a portable forest nutrient agent injection tool, including an injection cylinder 1, characterized in that: an adjustment component 2 is threadedly connected to the inner wall of the injection cylinder 1, and an injection component 3 is fixedly installed at the upper end of the injection cylinder 1;

[0029] Adjustment component 2 includes an adjustment plate 201, a telescopic rod body 202, a knob 203, a limiting rod 204, a piston rod 205, and a piston 206. The adjustment plate 201 is threaded to the inner wall of the syringe 1. The telescopic rod body 202 is fixedly installed at one end of the adjustment plate 201, and the knob 203 is fixedly installed at the other end of the telescopic rod body 202. The limiting rod 204 is slidably connected to the inner wall of the knob 203. Through the arrangement of adjustment component 2, pressure plate 4, locking block 5, and locking spring 6, the knob 203 is rotated first during use, thereby driving the adjustment plate 201. The syringe 1 is rotated while the operator observes the scale lines on the syringe 1 and moves the adjustment plate 201 to the scale where injection is needed. This facilitates the adjustment of the injection dosage and avoids injecting too much or too little, which would affect the effect. After the injection is completed, the pressure plate 4 is pressed, which drives the locking block 5 to compress the locking spring 6. The locking block 5 retracts into the injection needle 7, allowing the injection needle 7 to be removed. This makes it convenient to equip various specifications of needles for different types and thicknesses of trees. The needles are easy to replace, which can meet diverse injection needs and improve the versatility of the tool.

[0030] The injection assembly 3 includes an inlet 301, a microporous filter membrane body 302, a rotating shaft 303, a torsion spring 304, and a sealing plate 305. The inlet 301 is fixedly installed at the upper end of the injection cylinder 1. The microporous filter membrane body 302 is fixedly installed in the middle of the inner wall of the inlet 301, and the rotating shaft 303 is fixedly installed at the lower end of the inlet 301. Through the setting of the injection assembly 3, the required medicine is placed on the inlet 301, and then the medicine enters the injection cylinder 1 through the inlet 301. The microporous filter membrane body 302 can separate air from the medicine, ensuring that the medicine entering the injection chamber does not contain air, and avoiding residual air forming air emboli that enter the tree and thus harm the tree growth.

[0031] A piston rod 205 is fixedly installed at one end of the limiting rod 204, and a piston 206 is fixedly installed at one end of the piston rod 205. The piston 206 facilitates the intake of the liquid medicine into the syringe 1.

[0032] A torsion spring 304 is sleeved on the surface of the rotating shaft 303. A sealing plate 305 is fixedly installed on one end of the torsion spring 304. The sealing plate 305 prevents outside air from entering the syringe 1 after the liquid medicine enters the syringe 1.

[0033] One end of the syringe 1 is movably connected to a pressure plate 4, and the lower end of the pressure plate 4 is movably connected to a locking block 5. The locking block 5 is designed to cooperate with the locking spring 6 to hold the injection needle 7 in place.

[0034] A snap-fit ​​spring 6 is fixedly installed at the lower end of the snap-fit ​​spring 6, and an injection needle 7 is fixedly installed at the lower end of the snap-fit ​​spring 6. The injection needle 7 facilitates the injection of medicine into the trees.

[0035] A handle 8 is fixedly installed at the lower end of the syringe 1. The handle 8 is designed to make it convenient for staff to hold. A limit groove is provided on the inner wall of the knob 203.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: When using it, first turn the knob 203 to drive the adjustment plate 201 to rotate in the syringe 1. At the same time, the staff observes the scale line on the syringe 1 and moves the adjustment plate 201 to the scale where the injection is needed. This makes it easy to adjust the injection dosage and avoids injecting too much or too little, which would affect the effect.

[0038] The second step: Then, the required agent is placed on the inlet 301, and the agent enters the syringe 1 through the inlet 301. The microporous filter membrane body 302 can separate the air from the agent, ensuring that the agent entering the injection chamber does not contain air, and avoiding residual air forming air emboli that enter the tree and thus harm the tree's growth.

[0039] Third step: Finally, after the injection is completed, press down the pressure plate 4 to drive the locking block 5 to compress the locking spring 6. The locking block 5 retracts into the injection needle 7, so that the injection needle 7 can be removed. This makes it convenient to equip various specifications of needles for different types and thicknesses of trees. The needles are easy to replace, which can adapt to diverse injection needs and improve the versatility of the tool.
