Description

Technical Field

[0001] The present invention relates to the technical field of insect pest prevention spraying, and in particular to a forest insect pest prevention spraying device based on the protection of forest and grass resources. Background Art

[0002] In the field of forest and grassland resource protection, forest pest control is a key link in maintaining ecological balance and ensuring the healthy development of forestry. At present, forest pest control generally adopts the method of blanket spraying, that is, pests are controlled by spraying pesticides over a large area. However, this traditional spraying method has many disadvantages. On the one hand, due to the lack of accurate identification and positioning of pests, during the spraying process, the pesticides indiscriminately cover the entire area, which will not only cause harm to beneficial insects in the forest or cause their death, destroying the biodiversity of the forest ecosystem, but also cause waste of pesticide resources. On the other hand, for pests hiding in hidden locations such as under leaves, blanket spraying makes it difficult to ensure sufficient contact with the pesticides, resulting in the pests cannot be effectively eliminated, reducing the control effect.

[0003] In addition, the existing forest pest control technology has shortcomings in the treatment of the edge areas of pesticide spraying. After the pesticide is sprayed, the edge areas on both sides are often not eliminated due to the reduced concentration of the pesticide or incomplete coverage. The existing technology lacks effective marking and targeted treatment methods for these residual pests. It is difficult for staff to accurately determine the key areas for the next prevention and control, and they can only carry out repeated large-scale spraying, which further aggravates the waste of resources and the adverse impact on the ecological environment. Summary of the invention

[0012] Preferably, the suction pump sucks the fluorescent agent from the fluorescent barrel through the long pipe, transports it through the telescopic pipe to the nozzle, and performs fluorescence labeling on the pests that have not been eliminated at the edge of the insecticide.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The device adopts a dual liquid medicine barrel design. One liquid medicine barrel loads the pest attractant, and the other loads the insecticide; first, the attractant is sprayed through the atomizing nozzle to concentrate the pests in a preset area, avoiding the indiscriminate harm to beneficial insects in the forest caused by traditional covering spraying; after the pests are concentrated, switch to spraying the insecticide to achieve precise elimination of the target pests, significantly improving the insecticidal efficiency, and at the same time minimizing the harm to beneficial insects and maintaining the biodiversity of the forest ecosystem; the first driving component (including a DC motor, a first gear, a cross gear, and a first rack) drives the sliding plate to move in the sliding groove to realize the automatic docking and switching of the two liquid medicine barrels and the liquid medicine pump; this design does not require manual intervention, ensuring the automatic connection of the spraying processes of the attractant and the insecticide and improving the operation continuity.

[0014] 2. The infrared sensors on the carrier device can accurately identify the two side edge areas where the pesticide is sprayed by the atomizing nozzle. When detecting weakened pesticide efficacy or pests that have not been eliminated, the first braking motor is triggered to drive the second gear to rotate, driving the second rack to extend and retract, so that the nozzle of the marking device accurately aligns with the edge of the pesticide. The second braking motor can flexibly adjust the nozzle angle according to the inclination angle of the pesticide edge to ensure that the fluorescent agent is sprayed along the edge, fluorescently marking the pests that have not been eliminated. After the marked pests naturally gather, the staff can quickly lock the key area for the next prevention and control based on the range of the fluorescent mark, avoiding repeated large-area spraying of pesticides, reducing the amount of pesticide used, and reducing resource waste and ecological environmental pollution.

[0015] 3. The support plate is paired with four-corner support rods to form a stable base. The support block and the fixed rod cooperate to carry the spraying device to ensure the stable operation of the device on complex terrains. The infrared sensors are integrated on the carrier plate to monitor the spraying edge in real time, providing accurate signals for the marking operation. The second rack extends and retracts guided by the limit rod to avoid deviation. The telescopic pipeline extends adaptively as the nozzle moves to ensure smooth delivery of the fluorescent agent. The combined design of the fluorescent barrel and the suction pump realizes the continuous supply of the fluorescent agent, ensuring the continuity of the marking operation.

[0016] 4. Traditional covering spraying has problems such as great harm to beneficial insects, poor control effect in the hiding areas of pests, and lack of treatment in the edge areas, resulting in resource waste and ecological damage. Through the integrated process of "inducing - eliminating - marking", this invention combines precise prevention and control with ecological protection, not only improving the pest control efficiency, but also reducing the amount of pesticide used. At the same time, it provides a quantifiable marking basis for the scientific prevention and control of forest pests and diseases, promoting the intelligent upgrading of the technology for protecting forest and grass resources.

[0026] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process. The specific work is as follows. In forest pest control, pesticides are generally sprayed comprehensively on pests. The blanket spraying of pesticides on pests will cause certain harm or death to the beneficial insects in the forest. To protect the beneficial insects, this device is placed in the designated area. A liquid medicine bucket 28 with a pest attractant is sprayed through a liquid medicine pump 22 and an atomizing nozzle 21, so as to concentrate the pests and prevent harm to the beneficial insects. After staying still for a period of time, the pests fall within the range of the attractant. The direct current motor 212 drives the first gear 211 to align another liquid medicine bucket 28 filled with insecticide with the suction end of the liquid medicine pump 22. Similarly, the insecticide is sprayed through the liquid medicine pump 22 and the atomizing nozzle 21 to eliminate the pests. At the two side edges of the atomizing nozzle 21 when spraying the insecticide, the effect of the liquid medicine will definitely weaken or the pests at the edges may not be sprayed. At the same time, the infrared sensor 16 is used to identify the two side edges of the atomizing nozzle 21 when spraying the insecticide, and the signal is transmitted to the first braking motor 312 to drive the second gear 31 to rotate and drive two second racks 32, and two nozzles 36 are aligned with the two side edges of the insecticide to spray fluorescent agent to mark the pests that have not been eliminated. When there is a certain inclination angle at the two sides of the atomizing nozzle 21 when spraying the insecticide, two second braking motors 37 drive to adjust the angles of the two nozzles 36 to fit the two side edges of the insecticide, and the sprayed fluorescent agent marks the pests that have not been eliminated. And the pests that have not been eliminated will gather. According to the fluorescence indication, the next time the staff will centrally clean up the pests in the area with fluorescent marks. Moreover, this device improves the working quality of pest elimination and at the same time enhances the protection of beneficial insects in the forest.
