Description

Technical Field

[0001] The invention relates to the field of PPP, in particular to a spraying device for controlling harmful organisms. Background Art

[0002] Pest control refers to the use of various means to control, reduce or eliminate organisms that cause harm to human health, agricultural production and the ecological environment; these pests include pests, weeds, pathogens, nematodes, etc.; common pest control methods include chemical control, physical control and biological control; chemical control uses pesticides, insecticides and other chemical substances to kill or drive away pests, which is quick to take effect but prone to drug resistance and environmental pollution; physical control uses physical means such as capture, isolation, heat treatment, etc. to control pests, which is environmentally friendly but has a limited scope of application; biological control uses biological resources such as natural enemies, microorganisms, plant resistance, etc. to control pests, which is environmentally friendly and sustainable but has a slower effect; integrated control combines the above methods to achieve the best control effect; pest control requires selecting appropriate methods according to specific circumstances, and paying attention to environmental protection and sustainable development.

[0003] When controlling pests, it is necessary to spray pesticides, which are generally carried out by backpack sprayers. However, backpack sprayers have limited power when in use, so there is a time limit for use, which limits the device. At the same time, no matter what location or area, they need to be carried by humans, resulting in higher labor intensity. In addition, when using, the pesticides need to be poured manually. It is difficult to accurately control the amount of pesticides poured manually. If more is used, the pesticide is wasted, and if less is used, the pest control effect cannot be achieved. Therefore, a device is urgently needed to solve the above problems. Summary of the invention

9. A method for using a pesticide spraying device for pest control, characterized in that: The specific methods include the following: First, when in use, if the terrain is relatively flat and the height of the plant to be sprayed is lower than the spray head (3), the backpack (4) is fixed to the vehicle body (1), and then the sleeve rod (18) is sleeved on the movable rod (10), and then the vehicle body (1) is pushed to move. At this time, the movement wheel (5) rotates to drive the first sprocket (6) to rotate, and the second sprocket (9) is driven to rotate through the transmission chain (7), and then the movable rod (10) is pulled through the extension shaft (9), thereby driving the movable shaft (15) to move, so that the pressing block (24) moves up and down under the pressure of the movable shaft (15). When the pressing block (24) moves downward, the first piston block (26) moves along the first hollow block (2 5) Move downward, so that the air inside the first hollow block (25) is discharged through the second pipe (12), and then when the pressing block (24) moves upward, the first piston block (26) forms a negative pressure inside the first hollow block (25), and the negative pressure sucks the liquid medicine inside the backpack (4) into the first hollow block (25) through the first pipe (28), until the pressing block (24) moves downward again, injects the liquid medicine into the second pipe (12), and sprays it out through the nozzle (3), and the spraying operation is repeated in this way. At this time, the spraying does not consume energy, and the vehicle body (1) can be moved manually without having to carry the backpack (4), thereby reducing labor intensity; Secondly, when it is necessary to carry the backpack for use, the sleeve rod (18) is moved so that the spring (17) is squeezed and compressed, and then the movable shaft (15) is rotated so that the sleeve rod (19) moves to the position of the extension rod (14), and then the sleeve rod (18) is released. At this time, the spring (17) is reset, so that the sleeve rod (18) is sleeved on the outside of the extension rod (14), and then the fixing mechanism is released, and the backpack box (4) is carried on the back to take a new rod-shaped spray head and fix it on one side of the second pipe (12), and the electric push rod (13) is started to drive the pressing block (24) to move up and down, so that the liquid medicine is injected into the second pipe (12) and sprayed out from the end, so that the backpack box (4) can be carried on the back for use, and it is suitable for different locations and terrains, thereby improving the applicability of the device; Furthermore, when in use, the liquid medicine is poured into the storage tube (34), which is then sealed by the sealing cover (40), and then the hollow screw (35) is rotated to move the second piston block (37) downward inside the metering cylinder (36) until the remaining volume inside the metering cylinder (36) reaches the volume of the medicine to be added, and then the first solenoid valve (38) is opened, and the liquid medicine inside the storage tank (34) flows into the metering cylinder (36) to fill it, and then the first solenoid valve (38) is closed, and the second solenoid valve (39) is opened, and the quantitative liquid medicine flows into the backpack box (4), thereby completing the quantitative addition of the liquid medicine without manual work, thereby preventing waste and insufficient use of medicine.
