Background

The real-time and accurate identification of the diseases and insect pests of the forest is an important prerequisite for effectively carrying out the prevention and treatment work of the disease conditions and the insect conditions. At present, the diagnosis method of forestry diseases and pests in China mainly depends on manual identification, and has large subjective factors and poor real-time performance. Some pests are hidden in the trees during the juvenile period and gnaw the interior of the trees.

The traditional detection mode is that the trunk of the tree is observed by naked eyes, and whether insects are parasitized on the trunk of the tree is judged by subjective experience of people. A person needs to walk around the trunk and visually see whether there are wormholes at the bark of the tree. And the higher trunk is influenced by the sight line and is not beneficial to observation, and the condition of misjudgment often occurs. And the detection efficiency is very slow.

When wormholes are observed on the trunk of the tree. The trees need to be deinsectized.

The traditional deinsectization mode is divided into two modes, one mode is to spray insecticide on trees and spray the insecticide on trunks to kill insects. However, the above method has poor effect and low insecticidal efficiency. Another way is to open the slot on the bark and clamp the insects in the wormholes with tweezers. But this way causes some damage to the tree itself. And insects can continuously gnaw the interior of the tree, so that the wormholes are very deep and long sometimes. And some wormholes are old and may not have worms inside. Therefore, the number of the slotted barks cannot be too large, and the insects in the trees cannot be accurately found.

Therefore, the traditional deinsectization mode is complex and low in efficiency.

The screw rods 22 are connected with the rear ends of the two clamping pieces 1 in a threaded manner, and the screw rods 22 penetrate through the rear ends of the two clamping pieces 1. Thereby securing the two clips 1 together to form a ring. The two clamping pieces 1 are used for tightly holding the trunk of a tree, an electric push rod I7 is welded at the bottom of each clamping piece 1, and a clamping plate 8 is welded at the lower end of each electric push rod I7.

The inside spout 81 of having seted up of splint 8, spout 81 both sides and external intercommunication, sliding fit has slider 11 in the spout 81. One end of the sliding block 11 extends outwards towards the outer side of the clamping plate 8, and the other end of the sliding block 11 extends outwards towards the inner side of the clamping plate 8. The slider 11 is welded with laser transceiver 12 towards the inboard one end of splint 8, and laser transceiver 12 comprises laser emitter and laser receiver. The laser transmitter emits laser towards the pits on the surface of the tree, and the laser generates diffuse reflection to be received by the laser receiver. When no wormholes exist at the irradiation position after the laser is emitted, the laser is detected by the laser receiver through diffuse reflection. If wormholes exist after irradiation, part of light enters the wormholes, and part of the emitted light cannot be received by the laser receiver, the wormholes which go deep into the trees exist in the pits.

The laser transceiver is a conventional means, and thus the specific structure, circuit arrangement, model, and the like are the same as those of the prior art, and thus will not be described in detail.

The sliding groove 81 is arc-shaped, the sliding block 11 moves along the sliding groove 81 to enable the laser transceiver 12 to rotate around the tree, and the bottom of the clamping plate 8 is welded with a connecting part which is a chemical injection box 16.

Since there may be a certain bent passage inside the wormhole, the concave block 171, the connecting block 172, and the nozzle head 173 can be rotated, so that the entire medicine injection nozzle 17 can be deflected to the left and right. So that the injection nozzle 17 can be extended into the wormhole as much as possible.

The deflection is such that the thick iron wire 161 pushes the concave block 171 and the nozzle 173 at the front end touches the inner wall of the wormhole, so that the nozzle 173 is deflected to the untouched side. As the thick iron wire 161 continues to extend into the wormhole, the injection nozzle 17 is bent.

In order to prevent the medicine injection nozzle 17 from being stuck after entering the wormhole, the thick iron wire I161 cannot extend into the wormhole due to resistance. The continued insertion of the nozzle 17 is stopped. And the whole injection nozzle 17 has small size, 2cm long, 1cm wide and 1cm high, and the specific shape and size can be designed according to the actual situation.

When the tree pest control device works, the probe 21 is stretched into a tree pest hole, the lead 201 is pinched by hands and sent into the pest hole, and the lead 201 pushes the probe 21 to stretch into the pest hole. Ultrasonic waves are emitted by the ultrasonic transmitter 211 and then are detected by the ultrasonic receiver 212, so that the interior of the tree wormhole is detected. Confirming the specific conditions inside the wormholes as follows: where the worm is.

The image generated after the ultrasonic detection is displayed on the screen, and since this is the prior art, the specific devices, structures, circuit arrangements, connection modes, etc. are the same as the conventional techniques, and will not be described in detail and will not be shown in detail in the drawings.

Replace traditional mode to observe with the naked eye for detection efficiency.

And, through thick two 18 and the cooperation of tip cone 19 of iron wire, stretch into the wormhole with tip cone 19 in, expand the wormhole internal diameter slightly, the injection mouth 17 of being convenient for gets into the wormhole, rethread notes medical kit 16 and the cooperation of injection mouth 17, reach the effect of deinsectization in injecting the wormhole with the medicament, improve the contact rate of medicament and worm, further improved deinsectization efficiency.

Moreover, the probe 21 is extended into the wormhole by utilizing the mutual matching of the ultrasonic generator 20 and the probe 21, so that people can visually see the specific situation in the tree wormhole, people can know whether the wormhole is filled with the insects conveniently, the insect killing measure for the interior of the wormhole without the insects is avoided, and then the insects with the small depth in the wormhole are hooked out by means of the matching of the miniature electric push rod 214, the contact pin 215 and the barb 216.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
