Description

Technical Field

[0001] This utility model relates to the field of plant protection technology, specifically to a device for killing insects in tree holes of ancient trees. Background Technology

[0002] Tree cavities in ancient trees are formed over the years due to insect infestation or mechanical damage. Ants and insects like to settle in tree cavities and will gnaw on the tree. The location of the tree cavity is the most vulnerable part of the ancient tree. If it is not treated in time, it will endanger the life of the tree.

[0003] Currently, most pest control operations for tree cavities in ancient trees are still done manually. People use pesticide-assisted tools to dig out and remove ants and insects from the tree cavities, or spray pesticides into the tree cavities to achieve the desired effect. However, the distribution of tree cavities on ancient trees is irregular. Some tree cavities are located at the bottom of the trunk, where people can directly spray pesticides into the tree cavities with a pesticide spray gun. However, when the tree cavities are located in the middle or top of the trunk, it is necessary to build a ladder and climb to a higher position to spray pesticides into the tree cavities. Such pest control operations are not convenient for tree cavities located at higher positions on the trunk.

[0004] Therefore, a device for killing insects in tree holes of ancient trees is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an insecticidal device for tree holes in ancient trees. It guides the insecticide by setting up two relatively sliding support rods and a booster pump to pump the insecticide. When the tree hole is located at a high position, the height of the second support rod is adjusted to adapt to the height of the tree hole, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for killing insects in the cavities of ancient trees includes a first support rod, a second support rod, and a booster pump. Both the first and second support rods are hollow inside. A mounting plate is fixedly installed at the bottom of the first support rod, and the booster pump is fixedly installed at the bottom of the mounting plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides an insect-killing device for tree holes in ancient trees, the technical solution of which is as follows:

[0022] A device for killing insects in the hollows of ancient trees includes a first support rod 1, a second support rod 2, and a booster pump 4. Both the first support rod 1 and the second support rod 2 are hollow inside. A mounting plate 7 is fixedly installed at the bottom of the first support rod 1, and the booster pump 4 is fixedly installed at the bottom of the mounting plate 7. The output end of the booster pump 4 is connected to the inside of the first support rod 1. The second support rod 2 is slidably sleeved on the outer wall of the first support rod 1. A bent pipe 3 is threaded 13 at the top of the second support rod 2. A nozzle 12 is threaded 13 at one end of the bent pipe 3. The nozzle 12 has a circular nozzle opening.

[0023] The booster pump 4 is provided with a drug inlet pipe on its side. The drug inlet pipe is connected to an external drug loading box through a soft water pipe. The booster pump 4 draws out the drug from the drug loading box and pumps it into the support rod 1 and support rod 2. The drug rises to a high position through the support rod 1 and support rod 2 and is then sprayed out through the nozzle 12.

[0024] Support rod 2 can slide along the outer wall of support rod 1. When the tree hole is at a high position, support rod 2 can be pushed to move towards the top of support rod 1. The outer wall of the top of support rod 1 is provided with a left-hand thread 13, and the inner wall of the bottom of support rod 2 is also provided with a left-hand thread 13 that mates with the left-hand thread 13.
