Description

Technical Field

[0001] This utility model belongs to the field of tobacco control technology, specifically relating to a precision delivery device for tobacco control agents. Background Technology

[0002] Tobacco control generally includes agricultural control, biological and physical control, and chemical control. The main contents of chemical control are: precision application strategy: spraying highly effective systemic agents (such as compound sodium chloride powder) as "transplanting agents" during the seedling stage to control cutworms; alternating the use of agents with different mechanisms of action (such as deltamethrin and dimethomorph) during the field stage to delay the development of resistance; key period control: in areas with high incidence of viral diseases, strictly disinfect seedling tools during the seedling stage, test tobacco seedlings for viruses before transplanting, and discard infected seedlings; when removing seedlings under film, manually kill or use poison bait to kill cutworm larvae.

[0003] Currently, when using chemical methods to control tobacco pests and diseases, tobacco plants grow to different heights at different stages of their growth cycle. Existing pesticide dispensers generally have a fixed dispensing height, which leads to pesticide drift when sprayed at a higher height. This results in pesticides not being applied accurately to the tobacco plants, causing a waste of resources. Based on this, a precision pesticide dispenser for tobacco control is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed precision dispenser for tobacco control agents in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A precision dispenser for tobacco control pesticides includes a placement plate and a battery mounted on top of the placement plate. A mixing tank is fixedly connected to the top of the placement plate, and a lid is threaded onto the top of the mixing tank. A filter mechanism is installed inside the mixing tank, and a water pump is fixedly connected to the bottom of the mixing tank. The discharge end of the water pump is fixedly connected to a spraying frame via an injection pipe. The bottom of the spraying frame has spray holes, and an adjustment mechanism for adjusting the height of the spraying frame is fixedly connected to the placement plate.

[0007] As a further optimization of this utility model, the adjustment mechanism includes a fixed chamber fixedly connected to the top of the placement plate, a sliding plate slidably connected to the inner surface of the fixed chamber, a lifting motor installed on the top of the fixed chamber, a lifting screw fixedly connected to the output end of the lifting motor, the lifting screw passing through the sliding plate and connected to the sliding plate by threads, and the spraying frame being snapped into the end of the sliding plate.

[0008] As a further optimization of this utility model, the middle part of the sprayer is square, and the outer surface of the square part is in contact with the end of the slide plate.

[0009] As a further optimization of this utility model, a stirring motor is installed at the bottom of the mixing tank, and a stirring shaft is fixedly connected to the output end of the stirring motor. A slot is provided at the top of the stirring shaft, and the slot is set in the shape of a hexagonal prism.

[0010] As a further optimization of this utility model, the filtration mechanism includes a rod inserted into a slot, a cleaning rod fixedly connected to the top of the rod, a screen attached to the bottom of the cleaning rod, the rod passing through the screen and rotatably connected to the screen, a hanging ear fixedly connected to the top of the outer surface of the screen, and a hanging groove adapted to the hanging ear on the top of the mixing tank.

[0011] As a further optimization of this utility model, an air pump is fixedly connected to the top of the mixing tank, and an air injection pipe is fixedly connected to the exhaust end of the air pump. An air injection hole is opened at the bottom of the air injection pipe, and the air injection pipe is located inside the mixing tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the combined use of a lifting motor, lifting screw, fixed compartment, and sliding plate, can adjust the height of the spraying frame from the tobacco according to the growth of the tobacco when controlling pests and diseases. This reduces the problem of pesticide waste caused by excessive pesticide drift due to the high height of the spraying frame and pesticide, thereby achieving precise application of pesticides to tobacco and ensuring the quality of tobacco pest and disease control.

[0014] 2. This utility model achieves the filtration of water entering the mixing tank by using a filtration mechanism, a stirring motor, a stirring shaft, and a slot, thus preventing impurities in the water from clogging the spray nozzles. Furthermore, the stirring shaft can mix pesticides and water, improving the uniformity of pesticides in the water, thereby ensuring the uniformity of pesticide spraying.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a precision dispenser for tobacco control agents includes a placement plate 1 and a battery 2 installed on top of the placement plate 1. The battery 2 is replaceable to ensure that the agent can be applied at any time. A mixing tank 3 is fixedly connected to the top of the placement plate 1, and a lid 4 is threadedly connected to the top of the mixing tank 3. A filtering mechanism is installed inside the mixing tank 3. The filtering mechanism includes an insertion rod 19, a cleaning rod 18 is fixedly connected to the top of the insertion rod 19, and a handle is provided on the top of the cleaning rod 18. A screen 15 is attached to the bottom of the cleaning rod 18. The insertion rod 19 passes through the screen 15 and is rotatably connected to the screen 15. A hanging ear 16 is fixedly connected to the top of the outer surface of the screen 15. A hanging groove 17 adapted to the hanging ear 16 is opened on the top of the mixing tank 3. A water pump 5 is fixedly connected to the bottom of the mixing tank 3. The water pump 5 is electrically connected to the battery 2. The water pump 5 discharges... The liquid end is fixedly connected to the spray rack 7 through the injection pipe 6. The injection pipe 6 is in the form of a flexible tube. The bottom of the spray rack 7 has spray holes 8, which are arranged in an equidistant array at the bottom of the spray rack 7. An adjustment mechanism for adjusting the height of the spray rack 7 is fixedly connected to the placement plate 1. The adjustment mechanism includes a fixed chamber 9 fixedly connected to the top of the placement plate 1. A slide plate 10 is slidably connected to the inner surface of the fixed chamber 9. A lifting motor 11 is installed on the top of the fixed chamber 9. The lifting motor 11 is electrically connected to the battery 2. A lifting screw 12 is fixedly connected to the output end of the lifting motor 11. The lifting screw 12 passes through the slide plate 10 and is connected to the slide plate 10 by a thread. The spray rack 7 is snapped into the end of the slide plate 10. The middle part of the spray rack 7 is square, and the outer surface of the square part is in contact with the end of the slide plate 10.

[0024] When in use, the dispenser is installed in the tobacco field, with the sprayer 7 positioned directly above the tobacco. The lid 4 is opened, and a certain proportion of pesticide and water are added to the mixing tank 3. Water is filtered through a screen 15 while adding the water until the mixing tank 3 is full. During pest control, the height of the sprayer 7 is first adjusted according to the tobacco's growth. The lifting motor 11 is then activated, causing the lifting screw 12 to rotate, which in turn causes the sliding plate 10 to slide up and down within the fixed chamber 9. The sliding plate 10 will move the sprayer 7 up and down until its height is slightly higher than the tobacco. Then, the water pump 5 is activated, injecting the pesticide solution from the mixing tank 3 into the sprayer 7 through the injection pipe 6. Finally, the solution is sprayed onto the tobacco through the spray nozzle 8. This allows for adjustment of the sprayer 7's height relative to the tobacco based on its growth, reducing pesticide waste caused by excessive drift due to the higher height of the sprayer 7 and pesticide. This achieves precise pesticide application to the tobacco, ensuring the quality of pest and disease control.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a stirring motor 13 is installed at the bottom of the mixing tank 3. The output end of the stirring motor 13 is fixedly connected to a stirring shaft 14. A slot 20 is opened at the top of the stirring shaft 14, and a rod 19 is inserted into the slot 20. The slot 20 is set as a hexagonal prism. An air pump 21 is fixedly connected to the top of the mixing tank 3. An air injection pipe 22 is fixedly connected to the exhaust end of the air pump 21. An air injection hole 23 is opened at the bottom of the air injection pipe 22. The air injection holes 23 are arranged in an equidistant ring array along the bottom of the air injection pipe 22. The air injection holes 23 set at the bottom of the air injection pipe 22 can prevent pesticides from settling at the bottom of the mixing tank 3. The air injection pipe 22 is located inside the mixing tank 3.

[0026] When pesticides and water are added to the mixing tank 3 to prepare the pesticide solution, the stirring motor 13 and the air pump 21 are started, so that the stirring motor 13 drives the stirring shaft 14 to rotate, so that the stirring shaft 14 mixes the pesticides and water, improves the uniformity of the pesticides in the water, and thus ensures the uniformity of the pesticides sprayed. In addition, the stirring shaft 14 also drives the cleaning rod 18 to rotate along the inner bottom of the screen 15 through the slot 20 and the insert rod 19, so as to avoid the screen 15 from being blocked and causing water overflow, and ensures the smooth addition of water.

[0027] The operation of the air pump 21 will draw outside air into the air injection pipe 22, and then inject it downward into the liquid pesticide through the air jet hole 23. This can disrupt the surface tension of the liquid pesticide, allowing the pesticide and water to mix thoroughly, avoiding stratification or sedimentation, thereby ensuring a consistent concentration of the liquid pesticide during spraying, and also reducing the probability of clogging of the spray hole 8.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
