Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical spraying technology, and in particular to a pharmaceutical spraying device. Background Technology

[0002] In pesticide spraying devices for removing golden apple snails, the control of spray volume mostly relies on fixed-aperture nozzles and simple valves, which are difficult to adjust flexibly according to the density, resistance, and environmental conditions of the golden apple snails. This can easily lead to pesticide waste and poor control effects. Although adjustable valves exist, they still lack precise locking functions. During operation, vibration and accidental touches can easily cause flow deviations, affecting operational stability. A purely mechanical linkage adjustment and locking system is suitable for humid farmland environments, reduces equipment costs and maintenance difficulty, and significantly improves the accuracy and economy of golden apple snail control.

[0003] In agricultural and aquatic ecological management, pesticide spraying is a key means of controlling the invasive species Pomacea canaliculata. Existing pesticide spraying devices for removing Pomacea canaliculata mostly adopt backpack fixed nozzles and automated spray bar systems. During operation, manual pressing of the handle and starting of the motor are required, and the spray volume is roughly controlled by adjusting the pressure valve. The device has a high rate of pesticide waste due to flow control failure, and the control effect of Pomacea canaliculata fluctuates greatly, which seriously restricts the sustainability of ecological management.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see the appendix Figure 1 Appendix Figure 6 and attached Figure 7This utility model provides an embodiment of a pesticide spraying device, comprising a barrel shell 1, a flexible hose 8 fixedly connected to the bottom right side of the barrel shell 1, a connecting pipe 9 fixedly connected to the upper end of the flexible hose 8, a hollow tube 10 fixedly connected to the upper end of the connecting pipe 9, a connecting block 22 communicating with the upper end of the hollow tube 10, a plurality of limiting blocks 23 fixedly connected to the rear side of the connecting block 22, a stud 24 threadedly connected to the middle of the limiting block 23, a knob 35 fixedly connected to the top of the stud 24, a baffle 26 slidably connected to the inner wall of the connecting block 22, a rotating shaft 25 rotatably connected to the middle of the baffle 26, a rotating shaft 27 rotatably connected to the bottom surface of the baffle 26, and a rotating shaft 27 rotating on the outer wall of the rotating shaft 27.

[0036] Specifically, the stirring and cleaning mechanism 2 is ingeniously designed and functionally practical.

[0037] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 4 A controller 3 is fixedly connected to the left side of the barrel shell 1. A drain plug 7 is slidably connected to the bottom surface of the barrel shell 1. A water pump 19 is fixedly connected to the inner wall of the barrel shell 1.

[0038] Specifically, the controller 3 is fixed on the left side of the barrel shell 1 for easy operation of the device, the drain plug 7 is slidably connected to the bottom to facilitate the discharge of residual liquid in the barrel, the water pump 19 on the inner wall provides power for liquid transportation, the handle 4 on the top edge is equipped with an anti-slip sleeve 15, the barrel lid 6 is rotatably connected to the right side of the top surface, and the bottom has a rubber pad 20 and a filter screen 21, which can seal against leakage and filter impurities.

[0039] Please see the appendix Figure 1 Appendix Figure 2 Multiple grooves 16 are provided on the rear side of the barrel shell 1. The inner wall of the groove 16 is slidably connected to the protrusion 18. The outer wall of the protrusion 18 is fixedly connected to the shoulder strap 17. The top of the connecting block 22 is fixedly connected to the telescopic tube 11. The top of the telescopic tube 11 is fixedly connected to the bent tube 12. The top of the bent tube 12 is rotatably connected to the nozzle 13. The inner wall of the nozzle 13 is fixedly connected to the filter screen 14.

[0040] Specifically, the rear side of the barrel shell 1 has multiple grooves 16 that slide with the protrusions 18 on the shoulder strap 17 for easy carrying. The top of the connecting block 22 is connected to the telescopic tube 11 and the curved tube 12 in sequence, which can flexibly adjust the spray position. The nozzle 13 at the top of the curved tube 12 can rotate to meet the spray requirements at different angles, and the filter screen 14 on the inner wall can filter impurities.

[0041] Working principle: When adjusting the flow rate of the pesticide spray, manually press the pressure block 31 to make it slide the slider 30, and then lock it with the stud 24. It is not necessary to continuously press the pressure block 31 to control the flow rate of the pesticide. Pressing the pressure block 31 causes the baffle 26 to rotate around the rotating shaft 25 through the rotating shaft 27, so that the pesticide flows out through the inner wall of the connecting block 22. Releasing the hand spring 32 separates the connecting block 22 and the pressure block 31, and the baffle 26 rotates back to achieve the purpose of interception. The gasket 29 abuts against the rear side of the pressure block 31 to prevent the pesticide from flowing out and causing harm to personnel. The locking mechanism greatly promotes the accuracy and convenience of the work.

[0042] When mixing the reagents, turning the handle 202 causes the connected drive bevel gear 203 to rotate the driven bevel gear 205 below. The driven bevel gear 205 has a transmission pipe 206 connected through its middle. The transmission pipe 206 drives the stirring fan blades 207 and stirring rod 208 inside the tank to rotate, so as to facilitate the thorough mixing of the liquid. After the reagents are used up, connect the water pipe above the connector 204. The water flows through the transmission pipe 206 into the cross pipe 209. Alternatively, turning the handle 202 can rotate the cross pipe 209 around the transmission pipe 206, and the water flows out from the cross pipe 209 to rinse the tank wall from above, achieving the effect of cleaning after use. This provides convenience for personnel to clean after use, extends the service life of the equipment, and reduces maintenance costs.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
