[0026] like Figs. 1-2 The utility model provides an intelligent pesticide spraying device, comprising:

[0027] Car 1;

[0028] A spraying structure is provided on the trolley 1 and includes a liquid storage tank 3, a liquid spraying pipe 14, a medicine pump 16 and a spray head 18;

[0029] The stirring structure includes a driving motor 5, a stirring shaft and stirring blades. The driving motor 5 is arranged on the upper part of the liquid storage tank 3. The driving motor 5 is a dual-shaft motor. The first output shaft of the driving motor 5 is connected to the stirring shaft, and the stirring shaft and the stirring blades are connected to the stirring shaft.

[0030] The heating structure includes a first heating tube 22, a fixed box 2 and a gas drive assembly. The fixed box 2 is arranged above the liquid storage tank 3. The drive motor 5 is fixedly arranged in the fixed box 2. The fixed box 2 is provided with an air inlet 4 and an air outlet. The second output shaft of the drive motor 5 extends out of the fixed box 2. The second output shaft is connected to the gas drive assembly. The gas drive assembly is respectively connected to the air outlet and the first heating tube 22. The first heating tube 22 is arranged on the inner wall of the liquid storage tank 3. The first heating tube has an S-shaped structure. After the air flow passes through the first heating tube 22, it is discharged to the outside from the end of the first heating tube 22.

[0031] In this technical solution, the vehicle 1 can be an intelligent vehicle 1, which is a conventional product and has both unmanned and remote-controlled functions. The remote-controlled function can be an auxiliary function, allowing for flexible operation during field transfers and warehouse entry. The unmanned function enables autonomous operation, avoiding pesticide poisoning caused by manual operation of the sprayer, completely freeing up human operators and saving manpower. The liquid inlet of the drug pump 16 is connected to the liquid outlet at the bottom of the liquid storage tank 3, and the liquid outlet of the drug pump 16 is connected to the liquid spraying pipe 14. The spray head 18 is disposed on the liquid spraying pipe 14. When the drive motor 5 is in operation, the first output shaft of the drive motor drives the stirring shaft to rotate to uniformly mix the liquid in the liquid storage tank. The second output shaft of the drive motor drives the gas drive assembly to operate, allowing external cold air to enter the fixed box 2. The cold air cools the drive motor 5. The heated cold air enters the first heating pipe 22 to heat the liquid in the liquid storage tank 3, helping to increase the temperature of the liquid in the liquid storage tank 3, preventing the low temperature during spraying in cold weather from making the drug difficult to dissolve, and thus improving the drug solubility. The gas drive assembly may be a gas drive assembly consisting of a gas cylinder and a piston, or a gas drive assembly consisting of a fan and a transmission. When the gas drive assembly is a gas drive assembly consisting of a fan and a transmission, the fan may be disposed at the gas outlet, and the rotating shaft of the fan may be connected to the second output shaft via a worm gear to drive the fan to rotate, thereby driving the airflow in the fixed box into the second connecting pipe.

[0032] The working principle of this technical solution is as follows: water and medicine are added to the liquid storage tank 3, and the drive motor 5 is started. The drive motor 5 drives the stirring shaft 13 to rotate so that the medicine and water are evenly mixed. The drive motor 5 drives the gas drive component to work so that the external cold air flow enters the fixed box 2. After the air flow is heated by the heat generated by the drive motor in the fixed box 2, it is driven into the first heating tube 22 to increase the temperature of the liquid in the liquid storage tank 3. After the air flow passes through the first heating tube 22, it is discharged to the outside from the end of the first heating tube.

[0033] In another technical scheme, the gas driving assembly comprises the gas cylinder 6, the piston 8, the first connecting pipe, the second connecting pipe, the gas rod 7 and the eccentric wheel 9, the gas cylinder 6 is horizontally arranged above the fixed box 2, the gas cylinder 6 is connected with the gas outlet through the first connecting pipe, one end of the second connecting pipe is connected with the gas cylinder 6, the other end of the second connecting pipe is communicated with the first heating pipe 22, the first connecting pipe and the second connecting pipe are both provided with the one-way valve, the eccentric wheel 9 is fixedly connected with the second output shaft, the piston 8 is slidably arranged in the gas cylinder 6, the gas rod 7 is connected with the piston 8, and the gas rod 7 is slidably connected with the eccentric wheel 9. In the technical scheme, the first connecting pipe is provided with the first one-way valve 11, and the second connecting pipe is provided with the second one-way valve 10, wherein when the piston 8 moves to the right, the second one-way valve 10 is closed, and the first one-way valve 11 is opened to make the gas in the fixed box 2 enter the piston 8 gas cylinder 6; when the piston 8 moves to the left, the second one-way valve 10 is opened, and the first one-way valve 11 is closed, the piston 8 drives the gas in the gas cylinder 6 to enter the second connecting pipe, and the gas is discharged through the first heating pipe 22.

[0034] In another technical scheme, the outer periphery of the eccentric wheel 9 is provided with an annular dovetail groove, the gas rod 7 is provided with a connecting block, and the connecting block is slidably matched with the annular dovetail groove. The connecting block is clamped in the annular dovetail groove, and the connecting block is matched with the annular dovetail groove, so as to avoid that the pulling of the gas rod 7 on the connecting block causes the connecting block to be separated from the annular dovetail groove, so that the rotation of the eccentric wheel 9 can drive the gas rod 7 to reciprocate in the gas cylinder 6.

[0035] In another technical solution, a temperature sensor is provided at one end of the spray pipe 14 near the nozzle 18, a second heating pipe 17 is provided in the spray pipe 14, the second connecting pipe is connected to the first interface of the tee 19, the third connecting pipe is connected to the second interface of the tee 19, the third connecting pipe is connected to the first heating pipe 22, a first electrically controlled proportional valve 21 is provided at the second interface, the fourth connecting pipe is connected to the third interface of the tee 19, the fourth connecting pipe is connected to the second heating pipe 17, and a second electrically controlled proportional valve 20 is provided at the third interface of the tee 19; the temperature sensor, the first electrically controlled proportional valve 21, and the second electrically controlled proportional valve 20 are all electrically connected to the control device. When mixing the agent with water, the first electrically controlled proportional valve 21 is opened and the second electrically controlled proportional valve 20 is closed, so that the airflow enters the first heating tube 22 entirely through the third connecting tube. When spraying the agent, the control device adjusts the opening and closing degrees of the first electrically controlled proportional valve 21 and the second electrically controlled proportional valve 20 according to the temperature of the spray tube 14 detected by the temperature sensor, so as to adjust the airflow entering the second heating tube 17 through the fourth connecting tube, thereby adjusting the temperature of the liquid medicine flowing through the spray tube 14. This solves the problem that after the liquid medicine exits the spray tube 14, the temperature is low and the evaporation rate of the liquid medicine is slow, thereby preventing pests from inhaling the toxic gases after the liquid medicine evaporates, thereby reducing the insecticide effect. The airflow is discharged to the outside through the second heating tube 17. When the liquid medicine does not need to be heated, the second connecting tube can be removed from the tee. At this time, the hot airflow is discharged directly through the second connecting tube.

[0036] In another technical solution, the second heating tube 17 is a spiral structure, and the second heating tube 17 is sleeved inside the liquid spraying tube 14. The second heating tube 17 is arranged inside the liquid spraying tube 14, and the contact between the liquid and the second heating tube 17 is more sufficient, thereby improving the heat exchange efficiency.

[0037] In another technical solution, the second heating tube 17 includes multiple heating elements in a tapered spiral structure, which are connected in series to form the second heating tube 17. The tapered spiral structure of the heating elements creates turbulence when the liquid medicine flows in the liquid spray tube 14, resulting in more uniform heating of the liquid medicine.

[0038] In another technical solution, the top of the liquid storage tank 3 is an open structure. A removable tank cover 12 is provided on the top of the liquid storage tank 3, and the fixed box 2 is mounted on the tank cover 12. The tank cover 12 and the liquid storage tank 3 can be fixed by a snap fastener. The removable tank cover 12 facilitates cleaning of the interior of the liquid storage tank 3.

[0039] In another technical solution, a filter basket 15 is installed inside the liquid storage tank 3 and is removably connected to the lower surface of the tank cover 12. The filter basket 15 can be snap-fitted to the bottom of the tank cover 12 or threaded. The stirring blades, stirring shaft, and other components are located inside the filter basket 15. The tank cover 12 is equipped with a feed port to facilitate the addition of water, powdered medicine, or liquid medicine into the liquid storage tank 3. The filter basket 15 filters the mixed liquid medicine, preventing particulate matter from entering the spray gun and clogging the nozzle.

[0040] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
