[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a liquid pesticide preparation and spraying device for agricultural planting, comprising a water tank 1 and a medicine box 2 fixedly connected to the top of the water tank 1, the water tank 1 is pushed by a pushing handle 12, and a plurality of sets of casters 11 fixedly connected to the bottom of the water tank 1 are convenient for the overall movement, and a booster pump 13 fixedly connected to the surface of the water tank 1 sprays the agricultural solution configured in the inner cavity of the water tank 1 through a connecting pipe 14 through a spraying pipe 15 fixedly connected to the other end of the connecting pipe 14 to spray the pesticide.

[0022] For details, please refer to Figure 1-4 After the pesticide solution in the inner cavity of the water tank 1 is sprayed, pesticide is added to the inner cavity of the storage barrel 3 through the electronic valve 9, and water is added to the inner cavity of the water tank 1. As the horizontal surface of the inner cavity of the water tank 1 rises, the buoyancy ball 8 is affected by the buoyancy to move upward, and the buoyancy ball 8 pushes the control valve ball 6 to move upward at the same time through the linkage rod 7. Two groups of limiting grooves are opened on the inner wall of the storage barrel 3, and two groups of limiting rods 10 adapted to the limiting grooves are fixedly connected to the surface of the control valve ball 6 to ensure that the control valve ball 6 is displaced vertically. The buoyancy ball 8 moves upward and pushes the control valve ball 6 to move upward through the linkage rod 7. At this time, the control valve ball 6 is at the bottom of the storage barrel 3, and the inflow hole 17 opened at the bottom of the storage barrel 3 is fully opened. The pesticide added inside the storage barrel 3 flows into the inner cavity of the water tank 1 through the inflow hole 17, completing the automatic addition of pesticides.

[0023] For details, please refer to Figure 1-4 When the pesticide is added, the motor 4 arranged in the inner cavity of the water tank 1 is started, and the output end of the motor 4 drives the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives multiple groups of stirring rods 18 fixedly connected on the surface to stir the solution in the inner cavity of the water tank 1 to ensure that the injected pesticide and water are evenly mixed.

[0024] For details, please refer to Figure 1-4 With the spraying of pesticides, when the inner cavity of the water tank 1 drops again, the buoyancy ball 8 drops again with the drop of the water body, and the buoyancy ball 8 drives the control valve ball 6 to block and close the inflow hole 17 through the linkage rod 7. At this time, the sensor 16 senses that there is no liquid in the inner cavity of the storage barrel 3, and sends a signal to the electronic valve 9, so that the pesticide in the inner cavity of the medicine box 2 is filled into the inner cavity of the storage barrel 3 again through the electronic valve 9.

[0025] Working principle: Use the push handle 12 to push the water tank 1. The multiple sets of casters 11 fixedly connected to the bottom of the water tank 1 facilitate the overall movement. The booster pump 13 fixedly connected to the surface of the water tank 1 uses the connecting pipe 14 to spray the agricultural solution configured in the inner cavity of the water tank 1 through the spraying pipe 15 fixedly connected to the other end of the connecting pipe 14. When the pesticide solution in the inner cavity of the water tank 1 is sprayed, the pesticide is added to the inner cavity of the storage barrel 3 through the electronic valve 9, and water is added to the inner cavity of the water tank 1. As the inner cavity level of the water tank 1 rises, the buoyancy ball 8 Affected by the buoyancy, the control valve ball 6 is displaced upward. The buoyancy ball 8 pushes the control valve ball 6 to move upward at the same time through the linkage rod 7. Two sets of limiting grooves are opened on the inner wall of the storage barrel 3. Two sets of limiting rods 10 adapted to the limiting grooves are fixedly connected to the surface of the control valve ball 6 to ensure that the control valve ball 6 is displaced vertically. The buoyancy ball 8 moves upward and pushes the control valve ball 6 to move upward through the linkage rod 7. At this time, the control valve ball 6 is close to the bottom of the storage barrel 3. The inflow hole 17 opened at the bottom of the storage barrel 3 is fully opened, and the inside of the storage barrel 3 The added pesticide flows into the inner cavity of the water tank 1 through the inflow hole 17, completing the automatic addition of the pesticide. When the pesticide is added, the motor 4 set in the inner cavity of the water tank 1 is started, and the output end of the motor 4 drives the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the multiple groups of stirring rods 18 fixedly connected on the surface to stir the solution in the inner cavity of the water tank 1 to ensure that the injected pesticide and the water body are mixed evenly. With the spraying of the pesticide, when the inner cavity of the water tank 1 drops again, the buoyancy ball 8 drops again with the drop of the water body, and the buoyancy ball 8 is connected to the inner cavity of the water tank 1 through the linkage rod 7. The control valve ball 6 is driven to block and close the inflow hole 17. At this time, the sensor 16 senses that there is no liquid in the inner cavity of the storage barrel 3, and sends a signal to the electronic valve 9. The pesticide in the inner cavity of the medicine box 2 is filled into the inner cavity of the storage barrel 3 again through the electronic valve 9, and the pesticide is automatically added and stirred in a fixed amount, which solves the problem that the existing pesticide spraying device needs to manually add and stir the pesticide again after the pesticide solution is sprayed, the manual solution configuration ratio is inaccurate, and the manual addition efficiency is low, which affects the efficiency of pesticide spraying.
