[0002] As a key component of agricultural pesticide application machinery, pesticide sprayers are widely used for crop pest control on farms, weeding on livestock farms, and for forestry and agricultural pest control in forests, cattle farms, chicken farms, and pig farms. Traditional pesticide sprayer designs typically consist of an outer frame, a pesticide tank, a water pump, a nozzle, and a nozzle. Their working principle is to activate the water pump to spray the pesticide in the tank along the nozzle and out through the nozzle.

[0003] However, in actual applications, when adding solid drugs (such as powdered or granular drugs) to the medicine box, there is a problem of uneven mixing of the drugs and the solution, which affects the application effect. Therefore, in response to this situation, it is necessary to further design and improve the existing sprayer to improve the mixing uniformity of the drugs and the solution, thereby improving the application effect.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a pesticide sprayer which is easy to operate. Figures 1-4 As shown, it includes a frame 1 and a medicine box 2, and the medicine box 2 is installed at the lower part of the frame 1. A feed port is opened on the top of the medicine box 2, and a screw cover 3 is provided at the feed port. A fixing frame is fixedly installed in the middle of the frame 1, and the fixing frame is located directly above the medicine box 2. A water pump 4 and a bracket 5 are fixedly installed on the top of the fixing frame. The water suction port of the water pump 4 is connected to a water suction pipe, and the water outlet of the water pump 4 is connected to a drain pipe, and the drain pipe leads into the medicine box 2. A support is fixedly installed at the bottom of the frame 1, and a rotating shaft is rotatably connected in the support. The two ends of the rotating shaft are rotatably connected to rollers 20, which roll along the ground through the rollers 20 to facilitate the movement of the entire sprayer.

[0024] See also Figure 1-2 The top of the bracket 5 is rotatably connected to the winding roller 6, and a crank handle 7 is fixedly installed at one end of the front of the winding roller 6. An infusion tube 8 is wrapped around the middle of the winding roller 6. One end of the infusion tube 8 passes into the interior of the medicine box 2 and is connected to the built-in water pump. The other end of the infusion tube 8 is connected to the nozzle. A top cover 21 is provided on the top of the frame 1. The top cover 21 plays a role in sunshade and rain protection, and tries to prevent the mechanical parts of the sprayer from being exposed to the sun and rain and affecting their service life.

[0025] See also Figure 3-4A stirring assembly 9 is provided inside the medicine box 2. The stirring assembly 9 includes a servo motor 10 fixedly mounted on a fixed frame. A pulley 11 is fixedly mounted on one end of the output shaft of the servo motor 10. The bottom side of the fixed frame is rotatably connected to a pulley 2 12. A transmission belt is sleeved on the outer side of the transmission of pulleys 11 and 12. A rotating rod 13 is fixedly mounted on the bottom of pulley 2 12. A stirring rod assembly 14 is provided on the outer side of the rotating rod 13. By starting the servo motor 10, the pulley 11 will be driven to rotate, so the pulley 2 12 will be driven to rotate through the transmission belt, and then the stirring rod assembly 14 will be driven to rotate through the rotating rod 13, so that the medicine inside the medicine box 2 can be stirred and mixed, making the medicine mixture more uniform.

[0026] See also Figure 3-4 The stirring rod assembly 14 includes a fixed ring 15 fixedly mounted on the outside of the rotating rod 13. The fixed ring 15 is provided with three groups on the outside of the rotating rod 13. The outside of the fixed ring 15 is fixedly mounted with a support spring 16. The support spring 16 is arranged in an array of five groups around the fixed ring 15. The end of the support spring 16 is fixedly mounted with a fixed block 17. The fixed block 17 is connected to a counterweight rod 18 on the side away from the support spring 16. The counterweight rod 18 is suspended inside the medicine box 2 by the support spring 16. The outside of the counterweight rod 18 is fixedly mounted with stirring blades 19. Several stirring blades 19 are arranged in an array on the outside of the counterweight rod 18. The rotation of the rotating rod 13 drives the counterweight rod 18 to rotate around it as the axis, thereby stirring the medicine in the medicine box 2. The elasticity of the support spring 16 makes the counterweight rod 18 swing slightly during rotation, further improving the stirring effect. The number of support springs 16 arranged on the fixed ring 15 and its outer wall can be adjusted according to actual needs. When the easy-to-operate pesticide sprayer of the present invention is in use, first the roller 20 is used to conveniently push the pesticide sprayer to move, then one end of the water pump is connected to the water source, and the water pump 4 is started to draw water into the medicine box 2, and then the screw cover 3 is opened to pour medicine into the medicine box 2. After closing the screw cover 3, the servo motor 10 is started to drive the pulley 11 to rotate, and then the transmission belt can drive the rotating rod 13 to rotate, which can drive the support spring 16 and the counterweight rod 18 to rotate, and then the medicine liquid in the medicine box 2 can be mixed and stirred by the counterweight rod 18; at the same time, due to the elasticity of the support spring 16 itself, the counterweight rod 18 will shake slightly during rotation, which can further improve the stirring effect locally, and can also crush lumps or large particles of medicine. After mixing evenly, you can shake the handle 7 to drive the winding roller 6 to rotate, and then release the wound infusion tube 8. Then, hold the nozzle and spray the medicine on the designated location under the action of the built-in water pump in the medicine box 2. After the spraying of the medicine is completed, shake the handle 7 in the opposite direction to rewind the infusion tube 8.

[0027] Finally, it should be noted that the servo motor 10 and the like in this embodiment, and the electronic components in the above-mentioned parts are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected respectively through wires, and the specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.
