Description

Technical Field

[0001] This utility model relates to the field of forest pest control technology, and in particular to a forest trunk borer control device that can be fixed to the tree trunk. Background Technology

[0002] Forest borers are a major threat to forests, as they penetrate deep into trees and feed on them, causing trees to weaken or even die, severely damaging the forest ecosystem. The core purpose of eradicating these pests is to protect forest resources, maintain ecological balance, and ensure the sustainable development of the forestry industry, avoiding economic losses and ecological damage caused by pests. In the eradication process, trunk injection technology is used. The pesticide is injected into the trunk through a special syringe. The pesticide is then transported throughout the tree with the sap, precisely targeting the borers. This method not only effectively kills the pests but also reduces the pollution of the surrounding environment, achieving a green and environmentally friendly control effect and providing an effective guarantee for the healthy growth of forests.

[0003] Currently, trunk injection technology is widely used in the control of forest trunk borers. Most mainstream injection devices are disposable, typically consisting of a storage bag and an injection needle. During use, the needle is inserted into a pre-designed hole in the tree trunk. The height difference between the storage bag and the trunk creates a gravitational difference, allowing the pesticide to flow into the trunk by gravity. After complete injection, the entire device must be removed and recycled according to regulations. It cannot be reassembled or reused, and this method has significant limitations:

[0004] 1. Gravity-fed injection mode has a slow flow rate, and the injection time for a single tree is relatively long, resulting in low overall operation efficiency.

[0005] 2. The device cannot be reused, making it difficult to adjust the injection pressure and dosage according to the different life habits and depth of damage of different borers. This also increases the cost of consumables for each treatment and makes it difficult to meet the diverse needs of forest pest control. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Please refer to Figures 1 to 6 Example 1:

[0033] This utility model proposes a forestry trunk borer extermination device that can be fixed to the tree trunk, including: a fixing strap 2 and an extermination component, the extermination component being composed of a pesticide storage mechanism 3 and a pneumatic mechanism 4;

[0034] The medicine storage mechanism 3 includes a medicine storage box 301, an injection needle 302, and a mounting buckle 303. The injection needle 302 is fixedly installed at the bottom of the medicine storage box 301, and the mounting buckle 303 is fixedly installed on the back side of the medicine storage box 301. After the fixing strap 2 passes through the mounting buckle 303, the medicine storage box 301 is fixed to the tree trunk 1, and the injection needle 302 is inserted into the interior of the tree trunk 1. The air pressure mechanism 4 includes a sealing cap 401 and a control piston 402. The sealing cap 401 is screwed onto the top of the medicine storage box 301, and the control piston 402 is inserted into the top of the sealing cap 401.

[0035] The storage box 301 has a storage cavity 3011 inside, and the top of the injection needle 302 is connected to the storage cavity 3011. In use, after unscrewing the sealing cap 401 from the top of the storage box 301, the pesticide solution required to kill pests can be injected into the storage cavity 3011 inside the storage box 301. It can be reused, reducing the cost of use. The pesticide solution can be injected into the interior of the trunk 1 through the injection needle 302 that pierces the trunk 1, thereby achieving the operation of killing trunk-boring pests. It is convenient and flexible to use. The killing components can be selected in appropriate quantities according to actual needs and fixed in a suitable position on the trunk 1 at one time by the fixing strap 2, which further improves the flexibility and practicality of the device.

[0036] The sealing cap 401 has a functional cavity 4011 inside, and the control piston 402 is inserted into the functional cavity 4011. In use, the appropriate injection mode can be selected according to actual needs to inject pesticides to kill pests. After the sealing cap 401 is removed and reinstalled (relieving the original pressure inside the pesticide storage cavity 3011), the control piston 402 is lifted, and the killing component can be put into gravity injection mode. At this time, the outside gas can enter the inside of the pesticide storage cavity 3011 through the air inlet channel 4013, the functional cavity 4011 and the pressurization channel 4012 in sequence, thus providing a basis for the liquid inside the pesticide storage cavity 3011 to be injected by gravity. That is, at this time, the top of the pesticide storage cavity 3011 is not closed, and the pesticide can be injected into the inside of the tree trunk 1 by gravity through the injection needle 302, which is convenient and flexible to use.

[0037] The functional cavity 4011 has a pressurization channel 4012 located directly below it, with both ends of the pressurization channel 4012 connected to the functional cavity 4011 and the medicine storage box 301, respectively. The bottom side of the functional cavity 4011 has an air inlet channel 4013, with both ends of the air inlet channel 4013 connecting the outside of the sealing cap 401 to the functional cavity 4011. Both the pressurization channel 4012 and the air inlet channel 4013 are equipped with control check valves 414. During use, when pressurized injection is required, the pressurization operation is achieved by cyclically pulling the control piston 402 up and down. When the control piston 402 is pulled upward, external gas can enter the interior of the functional chamber 4011 through the air intake channel 4013. When the control piston 402 is pressed downward, the air inside the functional chamber 4011 can enter the interior of the storage chamber 3011 through the pressurization channel 4012, thereby increasing the pressure inside the storage chamber 3011. The control check valve 414 can strictly limit the gas flow direction during the pressurization process to ensure the stability of the pressurization operation. After that, the liquid medicine can be injected into the trunk 1 under pressure to kill pests. It is convenient and flexible to use.

[0038] The working principle of this embodiment is as follows: After unscrewing the sealing cap 401 from the top of the medicine storage box 301, the pesticide solution required for pest control can be injected into the medicine storage chamber 3011 inside the medicine storage box 301. It can be reused, reducing usage costs. The pesticide solution can be injected into the interior of the tree trunk 1 through the injection needle 302, thereby achieving the operation of killing trunk-boring pests. It is convenient and flexible to use. The appropriate number of pest control components can be selected according to actual needs and fixed to the appropriate position on the tree trunk 1 at one time using the fixing strap 2. A suitable injection mode can be selected according to actual needs for pest control. After removing and reinstalling the sealing cap 401 (relieving the original pressure inside the medicine storage chamber 3011), the control piston 402 is lifted, and the pest control component is in gravity injection mode. At this time, external gas can enter the system sequentially through the air intake channel 4013, the functional chamber 4011, and the pressurization channel 4012. The interior of the storage chamber 3011 provides a basis for gravity-based injection of the liquid inside the storage chamber 3011. That is, at this time, the top of the storage chamber 3011 is not closed, and the liquid can be injected into the trunk 1 by gravity through the injection needle 302. When pressurized injection is required, the pressurization operation is achieved by cyclically pulling up and down the control piston 402. When the control piston 402 is pulled up, external gas can enter the interior of the functional chamber 4011 through the air inlet channel 4013. When the control piston 402 is pressed down, the air inside the functional chamber 4011 can enter the interior of the storage chamber 3011 through the pressurization channel 4012, thereby increasing the pressure inside the storage chamber 3011. The control one-way valve 414 can strictly limit the gas flow direction during the pressurization process to ensure the stability of the pressurization operation. Afterwards, the liquid can be injected into the trunk 1 under pressure to kill pests.
