Description

Technical Field

[0001] This application relates to the technical field of pest control, and particularly relates to a pest control device for forestry seedling cultivation. Background Art

[0002] Forestry refers to the production department that protects the ecological environment, maintains ecological balance, cultivates and protects forests to obtain other forest products, and utilizes the natural characteristics of forest trees to play a protective role, and is one of the important components of the national economy.

[0003] During forestry seedling cultivation, pest control for seedlings is very important. It can reduce or prevent pathogenic microorganisms and pests from harming crops. Pest control generally can be divided into chemical control using chemical substances such as insecticides and physical control using physical energy such as light or rays or building barriers.

[0004] In the related art, during seedling cultivation, when spraying insecticidal liquid on the planted seedlings for pest control, usually only the stems and leaves of the seedlings can be sprayed with the insecticidal liquid, and it is not convenient to spray the insecticidal liquid into the soil where the seedlings are planted, resulting in the survival of pests, insect eggs or germs in the underground soil, and the poor ability to control soil pests, and thus the pest control effect on the seedlings is not ideal. Therefore, we propose a pest control device for forestry seedling cultivation to solve the above problems.

[0005] Through prior art retrieval, the following known technical solutions exist:

[0006] Prior Art 1: A forestry seedling pest control device disclosed in the authorized announcement number CN218043419U, including: a bottom plate, an installation plate fixedly connected to the top end of the bottom plate, and two insecticidal lamps arranged at the bottom end of the installation plate; a spraying mechanism for spraying the liquid medicine is arranged at the top end of the installation plate; an adjusting mechanism for adjusting the spraying range of the liquid medicine is arranged at the top end of the spraying mechanism; in this device, the spraying mechanism can use the stirring component to fully mix and stir the liquid medicine inside the tank body, thereby avoiding precipitation of the liquid medicine inside the tank body and ensuring the pest control effect of the liquid medicine. The conveying component can convey the liquid medicine to facilitate the spraying operation, and at the same time spray in multiple directions to improve the spraying effect of the liquid medicine. At the same time, the spraying mechanism and the insecticidal lamp are used in cooperation to effectively increase the pest control effect of the device. However, this prior art does not have the function of spraying insecticidal liquid into the soil where the planted seedlings are located to eliminate pests, insect eggs or germs in the underground soil.

[0007] Prior Art 2: A pest control device for forestry seedling cultivation disclosed in the authorized publication number CN209693844U. This pest control device for forestry seedling cultivation includes a base. The top of the base is fixedly connected to the bottoms of multiple liquid storage tanks. The top of the liquid storage tank is fixedly connected to the bottom of an infusion pipeline. A shut-off valve is fixedly connected to the middle of the infusion pipeline. The top of the infusion pipeline is fixedly connected to the bottom of a liquid pumping device. One end of an infusion hose is fixedly connected to the top of the liquid pumping device, and the other end of the infusion hose is fixedly connected to one side of a nozzle support. This pest control device for forestry seedling cultivation facilitates the use of designated drugs according to the disease conditions of forestry seedlings through multiple liquid storage tanks, and also reduces the time taken by the user to change drugs, facilitating the device to simultaneously treat the disease conditions of different forestry seedlings. The shut-off valve facilitates the adjustment of the spraying speed and also the adjustment of extracting the liquid medicine inside different liquid storage tanks. However, this prior art does not have the function of spraying insecticidal liquid medicine into the soil where the planted seedlings are located to eliminate pests, insect eggs or germs in the underground soil.

[0008] Through the above retrieval, it is found that the above technical solutions do not affect the novelty of the present invention; and the mutual combination of the above prior arts does not destroy the creativity of the present invention. Summary of the Invention

[0047] In this embodiment, it should be supplemented that a battery pack and a control switch are also installed on the vehicle frame 1. The motor 19, the first delivery pump 8, the second delivery pump 34, the battery pack and the control switch are electrically connected through wires. The battery pack is used to supply power to the motor 19, the first delivery pump 8 and the second delivery pump 34 respectively. The control switch is used to control the energized operation of the motor 19, the first delivery pump 8 and the second delivery pump 34 respectively. Their circuit connection mode and control mode belong to the mature technologies in this field, so they will not be elaborated in this article.

[0048] Through the above structure, the working principle of the forestry planting seedling pest control equipment provided by this application is as follows:

[0049] First, pour the insecticidal liquid medicine used for killing insects on the stems and leaves of the seedlings into the first liquid storage cavity 6, and pour the insecticidal liquid medicine used for killing insects in the soil where the seedlings are planted into the second liquid storage cavity 7. After pouring the liquid, screw the two plug cocks tightly into the corresponding liquid adding holes respectively. Then, push the whole seedling pest control equipment to the area where the seedlings need to be insecticide-controlled, and make the vehicle frame 1 of the seedling pest control equipment and the three wheels 2 located between two adjacent rows of planted seedlings, so that the seedlings are located between the two liquid spraying pipes 17, so as to ensure that the three wheels 2 will not press the seedlings when the equipment is pushed forward later;

[0050] Next, control the hydraulic cylinder 28 to extend and operate. The hydraulic cylinder 28 pushes the lifting seat 29, the soil-breaking plow head 30, and the hollow vertical shaft 31 to move vertically downward and gradually insert into the soil. The second shaft seat 40 drives the telescopic rod 38 to slide downward in the storage groove 37. The two limit blocks 39 on the telescopic rod 38 slide downward in the corresponding limit grooves respectively. At this time, the soil-breaking teeth 32 and the second nozzle 33 on the hollow vertical shaft 31 also gradually insert into the soil. According to the requirements of seedling planting, when the soil-breaking plow head 30 and the hollow vertical shaft 31 are inserted into the soil to an appropriate depth, stop the hydraulic cylinder 28 from extending and operating;

[0051] Subsequently, start the motor 19, the first transfer pump 8, and the second transfer pump 34 to operate, and push the entire device to move forward at a uniform speed. At this time, by utilizing the operation of the first transfer pump 8, the insecticidal liquid medicine contained in the first liquid storage chamber 6 can be pumped into the liquid inlet box 11. The insecticidal liquid medicine that enters the liquid inlet box 11 then flows into the hollow rotating shaft 12 through a plurality of liquid through holes 15, and then enters the hollow cross beam 16 and the two liquid spraying pipes 17 in sequence, and finally sprays out from a plurality of first nozzles 18 onto the root and stem surfaces of the plant seedlings for spraying insecticide on the root and stem surfaces of the plant seedlings. By utilizing the operation of the second transfer pump 34, the insecticidal liquid medicine contained in the second liquid storage chamber 7 can be pumped into the hollow vertical shaft 31 through the corrugated pipe 36. The insecticidal liquid medicine that enters the hollow vertical shaft 31 finally sprays out from a plurality of second nozzles 33 into the soil for spraying insecticide on the soil. By utilizing the rotation of the output shaft end of the motor 19 to drive the driving vertical shaft 20 to rotate, the driving vertical shaft 20 drives the main pulley 21, the telescopic rod 38, and the driving gear 41 to rotate. By utilizing the transmission effect of the main pulley 21, the auxiliary pulley 24, and the belt 25, the transmission shaft 23 can be controlled to drive the sector gear 26 to rotate. When the sector gear 26 meshes with the first driven gear 27, the hollow rotating shaft 12 is driven to rotate by a certain angle. Due to the torsion force generated by the torsion spring 14, when the sector gear 26 disengages from the first driven gear 27, the hollow rotating shaft 12 rotates back by a certain angle under the action of the torsion spring 14. In this way, the reciprocating rotation of the hollow rotating shaft 12 is realized, so that the hollow rotating shaft 12 drives the hollow cross beam 16, the two liquid spraying pipes 17, and a plurality of first nozzles 18 on the liquid spraying pipes 17 to perform reciprocating rotation. Furthermore, the insecticidal liquid medicine sprayed in a mist form from a plurality of first nozzles 18 can evenly spray the insecticidal liquid medicine on the seedling stems and leaves in different directions, avoiding uneven spraying or omission of the insecticidal liquid medicine, ensuring the overall uniformity of spraying the insecticidal liquid medicine on the seedling stems and leaves, improving the prevention and control effect of pests and diseases on the seedlings, as well as improving the utilization efficiency of the liquid medicine and reducing the waste of the insecticidal liquid medicine. By utilizing the meshing transmission effect of the driving gear 41 and the second driven gear 42, the hollow vertical shaft 31 can be controlled to drive a plurality of soil-breaking teeth 32 and a plurality of second nozzles 33 to rotate. At this time, by using the plowshare 30 in combination with the hollow vertical shaft 31 and a plurality of soil-breaking teeth 32 to insert into the underground soil, and controlling the hollow vertical shaft 31 to drive a plurality of soil-breaking teeth 32 to rotate, the soil for planting seedlings can be broken and loosened, and the roots of the seedlings will not be damaged. By utilizing the rotation of the hollow vertical shaft 31 to drive a plurality of second nozzles 33 to rotate, during the soil-breaking process, the insecticidal liquid medicine sprayed in a mist form from a plurality of second nozzles 33 can be evenly sprayed on the deep soil and around the soil-breaking teeth, so that the insecticidal liquid medicine penetrates into the soil, better acts on underground pests, insect eggs, or germs, enhances the prevention and control ability of soil pests and diseases, and further improves the prevention and control effect of pests and diseases on the seedlings.

[0052] Embodiment 2

[0053] Such as Figure 9 And Figure 10As shown in the figure, the structure of this embodiment is roughly the same as that of Embodiment 1. This embodiment is further optimized on the basis of Embodiment 1. In this embodiment, a vertical beam 43 is fixedly installed at the bottom of the frame 1. The hollow vertical shaft 31 is located between the vertical beam 43 and the soil-breaking plow head 30. A land leveling harrow 44 is fixedly installed at the bottom end of the vertical beam 43. Both sides of the land leveling harrow 44 are bent structures. The land leveling harrow 44 helps to level the land after spraying insecticidal liquid on the soil during the movement of the equipment, further optimizing the planting environment. Moreover, the bent structures on both sides of the land leveling harrow 44 can enhance its land leveling effect and adaptability to the soil.

[0054] Through the above structure, the working principle of the seedling pest control equipment for forestry planting provided by this application is as follows:

[0055] During the process of pushing the whole equipment forward at a uniform speed to spray insecticidal liquid on the stems and leaves of the seedlings and on the soil where the seedlings are planted, the vertical beam 43 and the land leveling harrow 44 at the bottom of the frame 1 move with the whole equipment. The land leveling harrow 44 can level the land after spraying the insecticidal liquid, and the bent structures on both sides of the land leveling harrow 44 enhance the land leveling effect.

[0056] The above has introduced in detail a seedling pest control equipment for forestry planting provided by this application. Specific embodiments are used in this article to elaborate on the principle and implementation mode of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this application, several improvements and modifications can still be made to this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
